Description

Overhead Ground Wire Riser

technical field

The utility model relates to a lifting device, in particular to an overhead ground wire lifter used when erecting ground wires.

Background technique

Most of the transmission lines are erected outdoors. When the wind blows, the lines will swing with the wind. They are in a state of micro-vibration for a long time, which may easily cause the overhead ground wires in the suspension clamps to break. In the past, during maintenance, the operator carried the wire to be replaced to the top of the pole, and then set up the wire. Since the replacement of high-altitude lines requires multiple people to cooperate, and the space on the top of the pole is small, the operating space is also small, so the old-fashioned way of changing lines is extremely dangerous to operators.

In order to solve the problem of high-altitude stringing, there are some lifting devices in the prior art that use pulleys and guy wires at high altitudes, and the new wires to be erected are lifted by the lifting of the guy wires. When it is connected with the pole, only the hoop is suitable for socketing, but the installation of the hoop requires positioning of its fastening bolts, and the hoop needs to be disassembled after application, which is cumbersome, especially when working at heights, and it is inconvenient to erect , not easy to operate. And if the bolt is loose when the hoop is installed, the hoop can easily slide down along the electric pole, causing an accident.

Contents of the invention

The purpose of the utility model is to propose an overhead ground wire lifter which can be stably erected on the top of the electric pole, is convenient for installation, and can quickly lift the ground wire to be erected.

The purpose of this utility model is achieved in that the overhead ground wire lifter is composed of a hoop, a crossbeam installed on the hoop, a suspension point arranged on the crossbeam, and a fixed pulley articulated on the suspension point. , the rear end of the beam is flexibly connected with the hoop, the middle part is placed on the hoop, and the front part protrudes from the hoop. Suspension points are arranged on the protruding part of the beam. One of the suspension points is connected with the fixed pulley. On the fixed pulley Wrapped with a safety cord. the

Due to the implementation of the above technical scheme, the utility model has a simple structure, which can be firmly placed on the top of the electric pole, and an anti-falling safety rope is provided to prevent the ground personnel from being injured by falling. The safety rope is also used to lift the ground wire to be erected. During use, ground wire aerial work can be carried out at any height. The application is easy to operate, can effectively reduce the number of workers working at heights, reserve enough work space for workers, and improve the safety factor of working at heights.

Description of drawings: the concrete structure of the present utility model is provided by following accompanying drawing and embodiment:

Figure 1 is a schematic diagram of the structure of the overhead ground wire lifter.

Legend: 1. Right support board, 2. Left support board, 3. Reserved suspension ring, 4. Positioning rope, 5. Front support board, 6. Rear support board, 7. Safety rope, 8. Fixed pulley, 9. Suspension ring, 10, support plate, 11, beam, 12, hoop.

Detailed ways:

The utility model is not limited by the following examples, and the specific implementation manner can be determined according to the technical scheme of the utility model and actual conditions.

Embodiment: As shown in Figure 1, the overhead ground wire lifter is composed of a hoop 12, a crossbeam 11 installed on the hoop 12, a suspension point arranged on the crossbeam 11, and a suspension hooked on the suspension point. Fixed pulley 8 forms. The rear end of the crossbeam 11 is flexibly connected with the hoop 12, the middle part is placed on the hoop 12, the front part stretches out from the hoop 12, and a suspension point is arranged on the extension of the crossbeam 11. One of the suspension points links to each other with fixed pulley 8, and safety rope 7 is wound on fixed pulley 8. A support plate 10 is provided at the lower end of the crossbeam 11 overlapping with the hoop 12 , and the support plate 10 is clipped to the outer circumference of the hoop 12 when the hoop 12 is closed.

The suspension points are respectively arranged at the front end of the crossbeam 11, the left and right sides of the front end and the middle part. The corresponding four suspension points include front, rear, left and right support plates 5, 6, 2, 1, and the reserved suspension ring 3 fixed at the upper ends of the front and rear support plates 5, 6, and the left and right support plates 2,1 the suspension ring 9 that upper end is fixed.

The beam 11 between the front and rear support plates 5 and 6 is tied with a positioning rope 4, and the positioning rope 4 is used for binding overhead ground wires when working at heights. Also the overhead ground wire can be directly carried between the front and rear support plates 5,6 or the left and right support plates 2,1.

In order to prevent the accidental crossbeam 11 from turning over at a high altitude, a locking device can be provided at the overlap between the crossbeam 11 and the hoop 12, for example: a screw hole is opened at the crossbeam 11, and a nut is fixed on the inner or outer wall of the hoop 12, and the bolt The crossbeam 11 and the hoop 12 can be completely fixed by screwing with the nut.

When in use, the circumference of the hoop 12 is roughly adjusted on the ground according to the circumference of the pole, and the operator carries the application to the upper end of the pole, and then puts the hoop 12 on the top of the pole until the crossbeam 11 touches the upper end of the pole, and the hoop 12 position. Then the fixed pulley 8 is suspended on any suspension point on the crossbeam 11, and the overhead ground wire is suspended by the positioning rope 4. At this time, the positioning rope 4 is subjected to a downward pull, and the crossbeam 11 is simultaneously subjected to a downward pull. Connected to the electric pole, so the application as a whole is not easy to loosen from the electric pole under the stressed state. Then check whether the overhead ground wire in the suspension clamp is broken, and the operator overhauls the overhead ground wire according to the actual situation. The safety rope 7 not only prevents the application from falling from a high altitude, but also can be used as a new line for conveying and waiting for a frame. Tie the new line to be erected on the safety rope 7, and the ground personnel will gradually pull the new thread to be erected to a high altitude by pulling the safety rope 7. After being pulled to the specified position, it is bound and positioned by the positioning rope 4 by the personnel working at heights for other use.

The above technical features constitute the best embodiment of the utility model, which has strong adaptability and best implementation effect, and non-essential technical features can be increased or decreased according to actual needs to meet the needs of different situations.
