Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Example 1

Please refer to Fig. 1, the oil cup 1 of the present embodiment is used for lubricating the elevator guide rail (not shown). A chute 9 matched with the elevator guide rail is set on the cup wall of the oil cup 1, and several electromagnetic valves 2 are arranged in the oil cup 1.

The chute 9 can be integrally formed on the oil cup 1, and is a channel formed by inward depression of the cup wall of the oil cup 1. At least one felt 3 is arranged on the groove wall of the chute 9, and each felt 3 corresponds to at least one solenoid valve 2, and the felt 3 is used to be attached on the elevator guide rail and when the chute 9 slides along the elevator guide rail, the The lubricating oil in the oil cup 1 is drawn out to lubricate the elevator guide rail. In this embodiment, the groove wall of the chute 9 has two opposite side groove walls and a connecting groove wall connecting the two side groove walls, and a felt 3 can be arranged on the two side groove walls and the connecting groove wall. And in this embodiment, three solenoid valves 2 corresponding to three felts 3 can be provided.

The spring in the electromagnetic valve 2 is connected with a tongue 8, and one end of the tongue 8 passes through the cup wall of the oil cup 1 and is connected with the corresponding felt 3. When the solenoid valve 2 is energized, the spring shrinks toward the solenoid valve 2 due to the electromagnetic force of the solenoid valve 2 and thus drives the tongue 8 to retract to pull the felt 3 away from the elevator guide rail. When the solenoid valve 2 is de-energized, the spring Because the solenoid valve 2 loses the electromagnetic force, it resets and thus pushes the corresponding tongue 8 out to push the corresponding felt 3 to stick on the elevator guide rail. The tongue 8 can be a cylindrical structure, so that the tongue 8 can pass through the cup wall of the oil cup 1 better. The tongue 8 is driven by the spring in the solenoid valve, so that the felt 3 can be well attached to the elevator guide rail.

The oil cup 1 of this embodiment, through the solenoid valve 2 arranged in the oil cup 1, let the solenoid valve 2 drive a tongue 8, and when the solenoid valve 2 loses power, the felt 3 loses the electromagnetic force due to the solenoid valve 2, The spring is reset, and the spring promotes the tongue 8 to make the felt 3 attach to the guide rail of the elevator. After the felt 3 is close to the guide rail, the whole elevator guide rail can be lubricated when sliding along the guide rail of the elevator through the chute 9. When the solenoid valve 2 is energized, the oil cup 1 receives electromagnetic force from the solenoid valve 2, and the spring is attracted by the solenoid valve 2 to shrink and deform. The contraction of the spring pulls the tongue 8 to retract and reset the felt 3, so that the felt 3 is separated from the After the elevator guide rail, the felt 3 is separated from the elevator guide rail, the oil cup 1 stops lubricating the elevator guide rail. Therefore, the oil cup 1 of the present invention is easy to use, can ensure the long-term stable operation of the elevator, and prolong the service life of the elevator.

In addition, the oil consumption of guide rail lubricating oil is seasonal, and the thinness of the oil is one of the main reasons for the oil consumption. When the temperature is high in summer, the temperature of the oil also rises accordingly, so the viscosity of the lubricating oil is lower than that in winter, and the linoleum in the oil cup 1 absorbs a lot of oil, so the oil consumption in summer is large. In winter, the temperature is low, and the temperature of the oil is also low, so the oil has a high viscosity and low fuel consumption. At the same time, the viscosity of lubricating oil is high in winter, and the oil temperature is low. When the elevator is running, the friction between the guide shoe and the guide rail may be increased due to the oil sticking, making the elevator run noisy and the comfort is poor. In summer, the oil is relatively thin and the oil temperature is high. When the felt 3 contacts the guide rail, the lubricating oil is more likely to be lost, and the oil consumption is particularly large. Therefore, lubricating oil with high viscosity at room temperature is used in summer, and lubricating oil with low viscosity at room temperature is used in winter.

Example 2

Referring to Fig. 2 and Fig. 3, the difference between the oil cup 1 of this embodiment and the oil cup 1 of embodiment 1 is that: the oil cup 1 is also provided with a control mechanism. The control mechanism includes a top trigger circuit, a bottom trigger circuit and a controller.

The top trigger circuit includes a magnetic strip one 5 and a proximity switch one 4 . Magnetic strip one 5 is arranged on the top of the elevator shaft (not shown) wall where the elevator (not shown) is installed. The proximity switch one 4 is arranged on the elevator and when the elevator runs to the top floor along the elevator guide rail 10, it is triggered by the magnetic strip one 5 and closed to send a trigger signal one. The installation positions of the magnetic strip-5 and the proximity switch-4 are not particularly required, as long as the following conditions can be met: when the elevator moves to the top floor along the elevator guide rail 10, the magnetic strip-5 is located at the side of the elevator shaft wall. Above, the proximity switch one 4 is positioned at the top of the car, and the proximity switch one 4 is triggered by the magnetic strip one 5 and closed to send the trigger signal one.

For example, the magnetic strip one 5 is located on the elevator shaft wall when the elevator runs to the top floor along the elevator guide rail 10, and correspondingly, the proximity switch one 4 is arranged on the top of the car of the elevator, so that the elevator When running to the top floor along the elevator guide rail 10, the magnetic strip one 5 is located above the elevator shaft wall, and the proximity switch one 4 can be triggered by the magnetic strip one 5 to close and send a trigger signal one. Specifically, the magnetic strip-5 can be installed on the top wall of the elevator shaft, and the proximity switch-4 can be installed on the top of the car of the elevator.

For another example, the magnetic strip one 5 is located above the elevator shaft wall when the elevator runs to the top floor along the elevator guide rail 10, and correspondingly, the proximity switch one 4 is arranged on the side of the elevator facing the magnetic strip one 5 When the elevator runs to the top floor along the elevator guide rail 10, the proximity switch-4 is located on the top of the elevator car, and the proximity switch-4 can be triggered by the magnetic strip-5 to close and send a trigger signal one. Specifically, the magnetic strip one 5 can be installed on the top of the elevator shaft wall, and the proximity switch one 4 can be installed on the car top corresponding to the magnetic strip one 5 of the elevator.

The bottom trigger circuit includes a magnetic strip two 7 and a proximity switch two 6 . Magnetic stripe two 7 is arranged on the below of the elevator shaft wall where elevator is installed. The proximity switch 2 6 is arranged on the elevator and when the elevator runs to the lowest floor along the elevator guide rail 10, it is triggered by the magnetic strip 2 7 to close and send a trigger signal 2. The second magnetic strip 7 is located below the elevator shaft wall when the elevator runs along the elevator guide rail 10 to the lowest floor. Proximity switch two 6 is arranged on the bottom of described elevator.

The controller counts to increase the number of times the elevator reaches the top floor according to the first trigger signal, and counts to increase the number of times the elevator reaches the bottom floor according to the second trigger signal. The controller also judges whether the total number of times the elevator reaches the top floor is not less than a preset value one, and if so, drives the solenoid valve 2 to be energized, otherwise continues to judge whether the total number of times the elevator reaches the bottom floor is not less than a preset value two, If yes, the solenoid valve 2 is driven to be energized, otherwise continue counting and then judge again. After the solenoid valve 2 is de-energized, the count of the controller can be reset to zero, and then the controller is made to repeat the entire lubricating process.

Please refer to FIG. 4 , the oil cup 1 of this embodiment, and its corresponding intelligent lubrication method for the elevator guide rail 10 may include the following steps.

Step S11 , when the elevator runs to the topmost floor along the elevator guide rail 10 , a trigger signal one is sent. In this embodiment, the proximity switch one 4 is triggered by the magnetic strip one 5 and is closed to send out a trigger signal one.

Step S12, according to the trigger signal one, counting and incrementing the number of times the elevator reaches the top floor. In this embodiment, this step is performed by the controller.

Step S13, when the elevator runs along the elevator guide rail 10 to the lowest floor, a trigger signal 2 is sent. In this embodiment, the trigger signal 2 is sent out when the proximity switch 2 6 is triggered by the magnetic strip 2 7 and closed.

Step S14, according to the trigger signal two, counting and increasing the number of times the elevator reaches the bottom floor. In this embodiment, this step is performed by the controller.

Step S15, judging whether the total number of times the elevator reaches the top floor is not less than a preset value one. In this embodiment, this step is performed by the controller.

When the total number of times the elevator reaches the top floor is not less than a preset value one, step S16 is executed to drive the solenoid valve 2 to be energized. In this step, the controller drives the electromagnetic valve 2 to be energized. After the electromagnetic valve 2 is energized, the felt 3 is separated from the elevator guide rail 10, and the lubrication of the elevator guide rail 10 is stopped.

Since then, the primary lubrication of the elevator guide rail 10 by the oil cup 1 has ended. The automatic circulation lubrication of the oil cup 1 to the elevator guide rail 10 can be designed by setting the controller. For example, when the solenoid valve 2 is energized, step S18 is executed to start timing until the time reaches a preset time. This step is performed by the controller. When the counted time reaches the preset time, step S19 is executed, the solenoid valve 2 is de-energized, all counts are reset, and the process returns to step S11. In this step, the controller drives the solenoid valve 2 to lose power. After the solenoid valve 2 loses power, the felt 3 is attached to the elevator guide rail 10, and the controller resets all counts, and the elevator guide rail 10 starts a new lubrication process again.

When the total number of times the elevator reaches the top floor is less than a preset value one, step S17 is executed to determine whether the total number of times the elevator reaches the bottom floor is not less than a preset value two. This step is performed by the controller.

When the total number of times the elevator reaches the bottom floor is not less than a preset value two, step S16 is executed. This step is performed by the controller.

When the total number of times the elevator reaches the bottom floor is less than a preset value two, step S11 is executed. This step is performed by the controller.

The oil cup 1 of this embodiment can realize periodic lubrication of the elevator guide rail 10 . Thereby, the utilization efficiency of lubricating oil can be increased.

In other embodiments, the contents of step S15 and step S17 may be replaced with each other. That is to say, the controller first judges whether the total number of times the elevator reaches the top floor is not less than a preset value two, and if so, drives the solenoid valve 2 to be energized; otherwise, continues to judge whether the total number of times the elevator reaches the bottom floor is not less than a preset value. If the value is set to one, if it is, the solenoid valve 2 is driven to be energized, otherwise continue to count and then judge again.

Example 3

The difference between the oil cup 1 of this embodiment and the oil cup 1 of Embodiment 2 lies in that the function of the controller has been adjusted.

In this embodiment, the controller is no longer: judging whether the total number of times the elevator reaches the top floor is not less than a preset value 1, and if so, drives the solenoid valve 2 to be energized; otherwise, continues to judge whether the elevator has reached the bottom floor Whether the total number of times is not less than a preset value two, if yes, drive the solenoid valve 2 to be energized, otherwise continue to count and then judge again; but: judge whether the total number of times that the elevator reaches the top floor is not less than a preset value one, yes Then continue to judge whether the total number of times that the elevator reaches the bottom floor is not less than a preset value two, and if so, drive the solenoid valve 2 to be energized.

The intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 in this embodiment is also different from the intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 in Embodiment 2. Please refer to FIG. 5 , the intelligent lubrication method for the elevator guide rail 10 of the oil cup 1 in this embodiment includes the following steps.

Step S21, when the elevator runs to the top floor along the elevator guide rail 10, a trigger signal one is sent. In this embodiment, the proximity switch one 4 is triggered by the magnetic strip one 5 and is closed to send out a trigger signal one.

Step S22, according to the trigger signal one, count and increment the number of times the elevator reaches the top floor. In this embodiment, this step is performed by the controller.

Step S23, when the elevator runs to the lowest floor along the elevator guide rail 10, a trigger signal 2 is sent. In this embodiment, the trigger signal 2 is sent out when the proximity switch 2 6 is triggered by the magnetic strip 2 7 and closed.

Step S24, according to the trigger signal two, count and increment the number of times the elevator reaches the bottom floor. In this embodiment, this step is performed by the controller.

Step S25, judging whether the total number of times the elevator reaches the top floor is not less than a preset value one. In this embodiment, this step is performed by the controller.

When the total number of times the elevator reaches the top floor is not less than a preset value one, step S26 is executed to determine whether the total number of times the elevator reaches the bottom floor is not less than a preset value two. This step is performed by the controller.

When the total number of times the elevator reaches the bottom floor is not less than a preset value two, step S27 is executed to drive the solenoid valve 2 to be energized. In this step, the controller drives the electromagnetic valve 2 to be energized. After the electromagnetic valve 2 is energized, the felt 3 is separated from the elevator guide rail 10, and the lubrication of the elevator guide rail 10 is stopped.

Since then, the primary lubrication of the elevator guide rail 10 by the oil cup 1 has ended. The automatic circulation lubrication of the oil cup 1 to the elevator guide rail 10 can be designed by setting the controller. For example, when the solenoid valve 2 is energized, step S28 is executed to start timing until the time reaches a preset time. This step is performed by the controller. When the counted time reaches the preset time, step S29 is executed, the solenoid valve 2 is powered off, all counts are reset, and the process returns to step S21. In this step, the controller drives the solenoid valve 2 to lose power. After the solenoid valve 2 loses power, the felt 3 is attached to the elevator guide rail 10, and the controller resets all counts, and the elevator guide rail 10 starts a new lubrication process again.

When the total number of times the elevator reaches the top floor is less than a preset value one, step S21 is executed.

When the total number of times the elevator reaches the bottom floor is less than a preset value two, step S21 is executed.

The oil cup 1 of this embodiment can realize periodic lubrication of the elevator guide rail 10 . Thereby, the utilization efficiency of lubricating oil can be increased.

In other embodiments, the contents of step S25 and step S26 may be replaced with each other. That is to say, the controller first judges whether the total number of times the elevator reaches the bottom floor is not less than a preset value two, and if so, continues to judge whether the total number of times the elevator reaches the top floor is not less than a preset value one, otherwise continues counting Judge again. And when it is judged whether the total number of times that the elevator reaches the top floor is not less than a preset value one, then the driving solenoid valve 2 is energized, otherwise continue to count and then judge again.

Example 4

Please refer to Fig. 6, the difference between the oil cup 1 of this embodiment and the oil cup 1 of Embodiment 2 is that the control mechanism of this embodiment only includes the trigger circuit at the top layer, and does not include the trigger circuit at the bottom layer, so the controller is also adjusted accordingly.

In this embodiment, the controller is no longer: judging whether the total number of times the elevator reaches the top floor is not less than a preset value 1, and if so, drives the solenoid valve 2 to be energized; otherwise, continues to judge whether the elevator has reached the bottom floor Whether the total number of times is not less than a preset value two, if yes, drive the solenoid valve 2 to be energized, otherwise continue to count and then judge again; but: judge whether the total number of times that the elevator reaches the top floor is not less than a preset value one, yes Then drive the solenoid valve 2 to be energized, otherwise continue to count and then judge again.

The intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 in this embodiment is also different from the intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 in Embodiment 2. Please refer to FIG. 7 , the intelligent lubrication method for the elevator guide rail 10 of the oil cup 1 in this embodiment includes the following steps.

Step S31 , when the elevator runs to the topmost floor along the elevator guide rail 10 , a trigger signal one is sent. In this embodiment, the proximity switch one 4 is triggered by the magnetic strip one 5 and is closed to send out a trigger signal one.

Step S32, according to the trigger signal one, counting and incrementing the number of times the elevator reaches the top floor. In this embodiment, this step is performed by the controller.

Step S33, judging whether the total number of times the elevator reaches the top floor is not less than a preset value one. In this embodiment, this step is performed by the controller.

When the total number of times the elevator reaches the top floor is not less than a preset value one, step S34 is executed to drive the solenoid valve 2 to be energized. In this step, the controller drives the electromagnetic valve 2 to be energized. After the electromagnetic valve 2 is energized, the felt 3 is separated from the guide rail 10, and the lubrication to the guide rail 10 is stopped.

Since then, the primary lubrication of the elevator guide rail 10 by the oil cup 1 has ended. The oil cup 1 can be designed to automatically circulate and lubricate the elevator guide rail 10 through the setting of the controller. For example, when the solenoid valve 2 is energized, step S35 is executed, and the timer is turned on until the time reaches a preset time. This step is performed by the controller. When the time of the timer reaches the preset time, step S36 is executed, the solenoid valve 2 is de-energized, all counts are reset, and the process returns to step S31. In this step, the controller drives the solenoid valve 2 to lose power. After the solenoid valve 2 loses power, the felt 3 is attached to the elevator guide rail 10, and the controller resets all counts, and the elevator guide rail 10 starts a new lubrication process.

When the total number of times the elevator reaches the top floor is less than a preset value one, step S31 is executed. This step is performed by the controller.

The oil cup 1 of this embodiment does not need to be provided with a trigger circuit at the bottom layer, which reduces the installation cost. Periodic lubrication can also be performed on the elevator guide rail 10, and the utilization efficiency of lubricating oil is high.

Example 5

Please refer to FIG. 8 , the difference between the oil cup 1 of this embodiment and the oil cup 1 of Embodiment 2 is that the control mechanism of the embodiment only includes the trigger circuit at the bottom layer, and does not include the trigger circuit at the top layer, so the controller is also adjusted accordingly.

In this embodiment, the controller is no longer: judging whether the total number of times the elevator reaches the top floor is not less than a preset value 1, and if so, drives the solenoid valve 2 to be energized; otherwise, continues to judge whether the elevator has reached the bottom floor Whether the total number of times is not less than a preset value two, if yes, drive the solenoid valve 2 to be energized, otherwise continue to count and then judge again; but: judge whether the total number of times that the elevator arrives at the bottom is not less than a preset value two, yes Then drive the solenoid valve 2 to be energized, otherwise continue to count and then judge again.

The intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 in this embodiment is also different from the intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 in Embodiment 2. Please refer to FIG. 9 , the intelligent lubrication method for the elevator guide rail 10 of the oil cup 1 of this embodiment includes the following steps.

Step S41, when the elevator runs to the topmost floor along the elevator guide rail 10, a trigger signal 2 is sent. In this embodiment, the trigger signal 2 is sent out when the proximity switch 2 6 is triggered by the magnetic strip 2 7 and closed.

Step S42, according to the trigger signal two, counting and increasing the number of times the elevator reaches the top floor. In this embodiment, this step is performed by the controller.

Step S43, judging whether the total number of times the elevator reaches the bottom floor is not less than a preset value two. In this embodiment, this step is performed by the controller.

When the total number of times the elevator reaches the bottom floor is not less than a preset value two, step S44 is executed to drive the solenoid valve 2 to be energized. In this step, the controller drives the electromagnetic valve 2 to be energized. After the electromagnetic valve 2 is energized, the felt 3 is separated from the elevator guide rail 10, and the lubrication of the elevator guide rail 10 is stopped.

Since then, the lubrication of the elevator guide rail 10 by the oil cup 1 has ended. The automatic circulation lubrication of the oil cup 1 to the elevator guide rail 10 can be designed by setting the controller. For example, when the solenoid valve 2 is energized, step S45 is executed to start timing until the time reaches a preset time. This step is performed by the controller. When the counted time reaches the preset time, step S46 is executed, the driving solenoid valve 2 is de-energized, all counts are reset, and the process returns to step S41. In this step, the controller drives the solenoid valve 2 to lose power. After the solenoid valve 2 loses power, the felt 3 is attached to the elevator guide rail 10, and all counts of the controller are reset, and the elevator guide rail 10 starts a new lubrication process.

When the total number of times the elevator reaches the bottom floor is less than a preset value two, step S41 is executed, and this step is executed by the controller.

The oil cup 1 of this embodiment does not need to be provided with a trigger circuit on the top layer, which reduces the installation cost. Periodic lubrication can also be performed on the elevator guide rail 10, and the utilization efficiency of lubricating oil is high.
