Working principle and process

The structure of a propeller excavator consists of two parts. The first part is the body part: the body part is composed of a flat hollow hull structure and excavator turntable, operating room, manipulator arm, tail support rod, etc.; the body adopts a flat structure to increase the contact area with the water surface and improve the operation of the manipulator arm. stability. The turntable and the mechanical arm are arranged in the front of the machine body, one is to increase the working area; the other is to provide auxiliary functions during the mechanical walking. Two hydraulically controlled tail support rods are provided at the rear of the body, which can not only meet walking assistance, but also serve as outriggers during operation. The second part is the screw propeller: the propeller is composed of 4 independent spiral cylinders, which are connected to the body by means of outriggers, and the angle is adjusted by a hydraulic rod. The spiral cylinder adopts a hollow design, which reduces the total amount of the whole machine while increasing the buoyancy and the stability of the whole machine during underwater operations. The hydraulic lever can adapt to different environments by adjusting the angle between the outrigger and the body. The independent setting of the rollers can better adapt to complex environments, such as sloped work surfaces or uneven geographic environments. The propeller selects four hydraulic motors to drive each screw barrel to provide the power for the whole machine to move forward. Since the propeller can provide forward power in the water, the propeller can be omitted or used as a spare option.

Refer to Figures 4 and 5 for details. The excavator adopts double helix propulsion for walking and sailing, and the steering function can be realized by the speed difference between the spiral drums on both sides. By adjusting the rotation direction of the drum, functions such as in-situ turning, multi-angle oblique movement, vertical and horizontal translation can be realized.

The rotation directions of the spiral fins of the four rollers on the same side and the front and rear rollers of the propeller are opposite, and the rotation directions of the spiral fins of the left and right rollers at the same end (front end or rear end) are opposite. The four propeller rollers are independently designed, and the steering and speed can be adjusted and controlled independently. Spiral drum can provide forward power on land, soft beach and water area. The angle between the spiral ribs of the drum and the axis of the drum can be matched according to the power output and the weight of the whole machine. The angle can be selected in the range of 15°-40°. The four rollers of the screw propeller are connected to the body with two legs and hinges respectively, and the angle between the legs and the body is adjusted and controlled by a hydraulic rod. The angle between the outriggers and the body is adjusted between 0°-90°, and the height of the body is propped up between 0-1 meters. It can meet the needs of normal walking, getting on and off, floating and sailing. The four groups of outriggers are set independently, so that the whole machine can be kept level when there is a slope or there are partial dents or protrusions under a certain group of outriggers. The hollow design of the four rollers of the propeller can provide the floating buoyancy of the entire body. By adjusting the angle between the drum leg and the machine body, the draft of the machine body can be adjusted. It can improve the stability of the whole machine during operation.

The propeller power motor is a two-way hydraulic drive motor. There are four hydraulic motors, each of which controls a spiral roller. The power of the propeller selected at the rear of the body is hydraulic drive motor, and the direction of the propeller is controlled by hydraulic rod.

Refer to Figure 6 for details, the number of tail support rods is two. The tail support rod is connected with the body through a hinge, and the angle is adjusted by a hydraulic rod. The hydraulic rod is divided into a fixed sleeve and a sliding rod. The fixed sleeve and the sliding rod are connected by a sliding pin, and the relative position is controlled by the hydraulic rod to realize the length adjustment of the support rod. The support rod can be used as a hydraulic leg to prop up the machine body, and can also be used as an anchor point in the working state to be inserted into the soil to stabilize the machine. The invention can be integrated with advanced detectors and electronic operating systems. The control panel selects iCP41 control panel, GNSS positioning receiver, rotation sensor, MSS301 stick sensor with laser receiver, MSS306 tilt bucket sensor, MSS300 boom sensor, etc. Enable the excavator to perform intelligent operations according to preset procedures.

Compared with other forms of dredging equipment, this machine can achieve amphibious operations. Driven by the screw propeller, this machine is very suitable for driving in snow, swamp, beach, jungle and other places. Under bad roads, it can show better adaptability and mobility. The four independent outrigger rollers can be adjusted individually to adapt to the uneven ground environment. Using rollers and tail support rods to assist the body, it can stably float on the water for operations. Normally it can adapt to 0-6m water depth area operations. By adding additional rods to increase the length of the tail support rod and change the working tentacles of the robotic arm, it can adapt to deeper waters and other work content.

Implementation of getting on, off and transportation: Driven by the screw propeller, the present invention is very suitable for driving in snow, swamp, beach, jungle and other places. However, when long-distance transportation or need to move on the road, choose the transport truck for consignment. The four outriggers (together with the hydraulic rod, the spiral roller, and the roller drive motor) can be separated and transported from the machine body. When disassembling, only the bolts of the machine body connecting bracket 16 and the oil pipe of the hydraulic rod 6 are released. During the dismantling process, the mechanical arm can be used as a lifting machine to assist dismantling without using other machinery. When the angle between the legs 5 on both sides and the body 1 is 90°, the distance between the rollers on both sides is not enough for the transport truck to drive downward. At this time, the angle between the outriggers and the machine body is adjusted by the hydraulic lever, so that the distance between the left and right spiral rollers meets the conditions for driving in. After the truck enters, continue to use the hydraulic lever to condition the angle between the outriggers and the body, so that the weight of the whole machine falls on the transport truck. Afterwards, remove the outriggers to complete boarding. When getting off the bus, the order is reversed, so I won’t repeat it.

Implementation of power transmission: each of the four spiral rollers is driven by a hydraulic motor. At this time, the power transmission between the spiral propulsion system and the body can be realized only through a few hydraulic oil pipelines. The outrigger angle adjustment hydraulic rod, the tail support rod angle adjustment hydraulic rod, and the length adjustment hydraulic rod all pass through the oil pipeline and can complete power transmission. In this way, the body reduces the relatively heavy transmission shafts, gears, chains and other components, and reduces the weight of the whole machine, so that it has a small volume to float on the water surface for implementation. The power machinery is driven by an internal combustion diesel engine to drive the hydraulic oil pump to provide the working power of the whole machine.

Implementation of normal driving and steering: When the present invention is driving normally, the four spiral drums 4 rotate at the same time. The rotation directions of the spiral fins of the four rollers on the same side and the front and rear rollers of the propeller are opposite, and the rotation directions of the spiral fins of the left and right rollers at the same end (front or rear) are opposite. When moving forward, the rotation directions of the four rollers (observed from the front of the station) are: front left clockwise, left rear counterclockwise, right front counterclockwise, and right rear clockwise; when moving backward, the above is the opposite. When turning to the left, the rotation of the two rollers on the left side decreases or stops, and the power on the right side is obviously stronger than that on the left side, and it can complete the left turning. At this time, the left roller rotates in the opposite direction, and the machine body can be turned to the left. If the four rollers are adjusted to rotate in the same direction, the lateral movement of the body can be realized. If the two rollers on the front side rotate in the same direction at a high speed and the two rollers on the rear side rotate in the same direction at a low speed, transverse fan travel can be realized to meet the operating requirements of special areas.

Adaptability to sloped terrain and local concave (convex) environment: The angle between the outriggers and the body can be adjusted by hydraulic levers to achieve height adjustment between the body and the ground. When the outriggers are perpendicular to the body, it is a typical state of walking on land, and when the outriggers are parallel to the body, it is a typical state of traveling on the water. The angle of the outriggers can be adjusted according to different environments. Adjusting the two sets of outriggers at the front or rear can realize operations along the slope, and adjusting the two sets of outriggers on the left or right can realize operations perpendicular to the slope. When there are pits or bumps under a certain group of legs, a certain leg can be adjusted individually to make the whole machine more stable.

Implementation of surface operations: the body is hollow design, with reinforced ribs inside to ensure the overall strength requirements. In order to reduce the volume and weight of the whole machine, the displacement of the main body does not need to meet the weight of the whole machine, but can be larger than the weight except the propeller system. It can ensure the independent operation on the water surface after the system of the propeller connecting the leg and the drum is removed. At this time, only need to add a small auxiliary propeller. The interior of the four spiral drums is hollow, which reduces the overall mass while providing floating power to make the whole machine work more stable. The displacement of the four drums is greater than the weight of the whole machine, which can provide the floating force of the whole machine without relying on the buoyancy of the machine body. By adjusting the angle of the outriggers, the draft of the drum during horizontal driving (operation) can be controlled, so that the draft of the body can be adjusted, and the body can be lifted completely to get the body out of the water. During operation, the outriggers are fully extended, and the five contact points with the water surface greatly increase the stability of the body. The screw-propelled excavator is capable of amphibious operations and can drive directly from the shallows into the river. Four drums can be rotated to provide the navigation power of the whole machine.

Implementation of the support rod: The tail support rod can realize the support function of the support rod at different angles and different depths through the angle adjustment hydraulic rod and the length adjustment hydraulic rod. It can push the body forward and upward, which can also assist walking. During operation, the support rod can be used as an anchor point to insert the support rod into the soft soil to fix the machine body and improve the stability during work. When working in deeper waters, an auxiliary extension rod can be added to the lower end of the support rod to ensure that the support rod can penetrate deep into the river bottom. The design strength of the support rod can meet the requirements of supporting the whole machine with the excavator arm or propeller leg. Support rods, robotic arms, and propeller legs cooperate with each other to basically satisfy all-terrain walking.

Implementation of intelligent operation: The GNSS positioning device of the present invention can accurately find the operation site through coordinates without obvious reference objects. Trial excavation before operation can detect the depth of dredging. At the same time, the computer system equipped on the excavator records the sensor data of each mechanical component movement, that is, records the movement range of the turntable, bucket, robotic arm and other components. After the exploration is completed, the program can be input in the computer, and the subsequent automatic operation can be completed. The input program includes position range information and various sensor data to control the motion range of the robot arm and turntable to complete the automatic operation.

Implementation of other operations: In addition to simple excavation operations, the auger excavator can achieve other functions through simple modification. For example, replacing the mechanical arm bucket with a hinged suction head can achieve hinged suction dredging; replacing the bucket heel with a pressure grouting head, which can become a riverbed (beach) reinforcement machine. The flat hull structure of the screw-propelled excavator and the combination of the screw propeller can become the carrier of a variety of machinery. After disassociating the excavator from the turntable and the body, it can be combined to install a concrete pump device to become a screw-propelled concrete pump truck; after the combined installation of piling equipment, it becomes a pile driver and so on.

The detailed description of this fast-reaction screw-propelled excavator with reference to the above examples is illustrative rather than restrictive. Several examples can be listed according to the limited scope, so without departing from the general concept of the present invention The following changes and modifications should fall within the protection scope of the present invention.
