Description

Tooling for emergency maintenance of power transmission lines

technical field

The invention relates to the technical field of electric power maintenance, in particular to an emergency maintenance tool for power transmission lines.

Background technique

Elevated cables (also known as overhead cables) are special forms of transmission lines that are supported by electric poles and erected in the air above the driving track of electric-driven vehicles, and are used to directly supply power to them when they are in contact with them. In use, there may be breakage. After the cable is broken, workers usually need to go up to the high-altitude cable for docking. Not only is the wind speed high in the high altitude, but the contact point between the worker and the cable is relatively small, and it is easy to slip, making the worker Dangerous.

At present, the existing emergency maintenance device for power transmission lines (such as patent publication number: CN113659495A) discloses a device for butt jointing of high-altitude high-voltage cables, which includes a housing. A control terminal is fixed inside one side of the housing. There is a docking cavity and a sleeve groove whose opening is away from the shell, a fixing mechanism is provided in the docking cavity and the side of the shell away from the docking cavity, a sleeve mechanism is installed in the sleeve groove, and a squeezing mechanism is installed in the sleeve mechanism. The man-machine drives the device above the power-off cable, the inner sleeve fixing ring drives the fixed protective sleeve to cover the cable core, and the guide plate rides on the other half of the cable core to guide the cable core to prevent the cable from being connected during the docking process. Deviation occurs, so that the cable core is not connected to the fixed protective sleeve.

However, during the implementation of the above-mentioned technical solutions, it was found that at least the following technical problems existed:

1. The operation is cumbersome: when the existing emergency maintenance device for power transmission lines is in use, it is necessary to control the movement and docking of the UAV-driven device, but this process not only requires precise control of the movement of the UAV (that is, it takes a lot of time) and energy), and at the same time prevent other cables (or objects, weather, etc.) It cannot be promoted quickly and effectively, seriously affecting the efficiency and convenience of cable docking;

2. The structure is complicated and the stability is poor: when the existing emergency maintenance devices for power transmission lines are in use, due to their many structures and the close cooperation between each structure, it is necessary to ensure the safety of each structure whether it is production or use. Stability (the staff cannot quickly install and check), so the overall effect of the device is not good. For this reason, we propose an emergency maintenance tool for power transmission lines.

One end of the traction rope 2 is connected to the connecting shaft 14 of one of the locking components 1, and the other end passes through the transmission wheel 13 of the other locking component 1 and extends to the ground, so the user only needs to pull the interface of the traction rope 2 to make the two Pull the two cable ends together to facilitate the subsequent docking, as shown in Figure 2, at this time the two ends of the cable are close to each other, and finally butt together to complete the cable docking.

In some examples, the clamping ring includes a first clamping ring 11 and a second clamping ring 12 corresponding to each other, and the ends of the first clamping ring 11 and the second clamping ring 12 are connected by bolts, so the two clamping rings can be rotated The bolts between the rings reduce the gap between the two clamping rings, so that they are clamped on the outside of the cable, and the locking assembly 1 and the cable are fixedly connected together;

Wherein, both ends of the first clamp ring 11 are connected with a second ear plate 18, and the second ear plate 18 corresponds to the first ear plate 17 at the end of the second clamp ring 12;

Bolts are connected between the first lugs 17 and the second lugs 18 corresponding to each other, as shown in Figure 5, during the rotation of the bolts, the two lugs are kept away from each other. The cables between the two clamping rings are clamped, so that the locking assembly 1 and the cables are connected together, and at the same time, cables with different diameters can be uniformly clamped, thereby improving the scope of application of the device.

Wherein, the inner walls of the first clamping ring 11 and the second clamping ring 12 are bonded with insulating pads, thereby achieving the effect of insulation, and the inner walls of the insulating pads are provided with anti-slip threads, which can increase the distance between the locking assembly 1 and the cable. Friction, improve the stability of the connection.

In the specific implementation process, the cable to be fixed is first inserted into the gap between the two clamp rings, and then the bolts between the clamp rings are rotated so that the two ear plates at the ends of the clamp rings are far away from each other. The ends of the rings cross each other, so when the two lugs move away from each other, the gap between the clamp rings is continuously reduced, so that the cable inserted between the clamp rings is clamped, so that the cable and the locking assembly 1 are connected in the Together, at this time, the two locking assemblies 1 are respectively connected to the two cable ends to form a shape as shown in FIG. 2 .

After the cable end is fixed, pull the traction rope 2 on one side of the locking assembly 1, so that the traction rope 2 moves outward along the transmission wheel 13, that is, the traction rope 2 connected between the two locking assemblies 1 is continuously pulled Pull it out, thereby shortening the traction rope 2 between the two locking components 1, so that the ends of the cables are close to each other, and stop when the ends of the cables are close to the specified distance. At this time, the ends of the two cables are attached to each other, and the Normal power-on is convenient for subsequent use. Secondly, the cable ends can be approached first, and then the staff can connect and fix the cable ends, thereby reducing the staff's working time at heights.

Example 2

Based on Embodiment 1, the embodiment of this application effectively solves the technical problem of the stability of the cable connection when the existing power transmission line emergency maintenance device is in use. The general idea is as follows:

The outside of the transmission wheel 13 is connected to the limit cylinder 5, and the limit cylinder 5 is used to limit the moving direction of the traction rope 2, so that the traction rope 2 can only move outwards, but cannot move inward (that is, to the two locking components). 1), the traction rope 2 between the transmission wheel 13 and the connecting shaft 14 passes through the limit cylinder 5, thereby locking the traction rope 2 passing through it;

Wherein, the limit cylinder 5 includes a sleeve 51, and a corresponding ring 54 is installed inside the sleeve 51, the corresponding ring 54 corresponds to the limit pin 52 sleeved outside the traction rope 2, and the inner wall of the corresponding ring 54 and the limit pin The outer walls of 52 are all conical, so when the traction rope 2 drives the stop pin 52 to move towards the corresponding ring 54, the stop pin 52 connected with the cable cannot pass through due to the shrinking inner wall, so it can only move in the other direction. move.

In some examples, the limit pin 52 includes a plurality of clamping blocks, and the shape of the multiple clamping blocks is conical after they are attached to each other, which is convenient for use with the corresponding ring 54;

Among them, two adjacent blocks are connected by an elastic rope (like a bracelet), so that the blocks are connected together, and the scattered distribution of the blocks is avoided. Secondly, during installation, it is only necessary to stretch the blocks at the end of the cable. The head is inserted, and the block is released, so that the block is set on the outside of the traction rope 2 under the action of the elastic rope. In addition, when the traction rope 2 moves outward, the direction slides relative to the surface of the cable.

In some examples, the inner wall of the sleeve 51 is threadedly connected with a retaining ring 53, and the retaining ring 53 is located at the rear end of the limit pin 52, thereby preventing the limit pin 52 from moving out of the sleeve 51, thus limiting the movement of the limit pin 52. Location;

Wherein, the limit pin 52 is located in the gap between the retaining ring 53 and the corresponding ring 54 , thereby limiting the range of movement of the limit pin 52 and preventing the limit pin 52 from moving out of the sleeve 51 .

In some examples, an extension rod 6 is connected between the transmission wheel 13 and the limit cylinder 5, and the transmission wheel 13 and the limit cylinder 5 are connected through the extension rod 6, so that the limit cylinder 5 and the transmission wheel 13 are connected Together, they can move relative to each other at the same time;

Wherein, one end of the extension rod 6 is movably connected with the center of the transmission wheel 13 , and the other end of the extension rod 6 is movably connected with the outside of the limiting cylinder 5 .

In the specific implementation process, first put the limit pin 52 on the outside of the cable, then push the limit pin 52 into the sleeve 51, and screw the stop ring 53 into the sleeve 51, and connect with the back of the sleeve 51. At this time, the limit pin 52 is located in the gap between the retaining ring 53 and the corresponding ring 54, so when the traction rope 2 is pulled outward (that is, moves in a direction other than the two locking assemblies 1), this , the traction rope 2 moves towards the stop ring 53, and the stop pin 52 blocks the movement of the stop ring 53, so that the stop pin 52 cannot move outward from the stop ring 53, and because the stop pin 52 at this time is not affected by the corresponding ring. 54 can be freely expanded, so the relative movement between the limit pin 52 and the traction rope 2 can occur, so that the limit pin 52 is always limited between the stop ring 53 and the corresponding ring 54.

And when the traction rope 2 moved to the direction of the corresponding ring 54, because the outer wall of the stop pin 52 and the inner wall of the corresponding ring 54 were all tapered, and the stop pin 52 was made up of a plurality of scattered blocks, so when the stop pin 52 52 moves to the direction of the corresponding ring 54, the limit pin 52 is subjected to the resistance of the corresponding ring 54, making it tightened. The pin 52 is separated, so the traction rope 2 can no longer move towards the direction of the corresponding ring 54, thus causing the traction rope 2 to move in one direction.

At this time, the two cable ends communicate with the copper seat 4 through the copper pin 3 , to complete the connection of the cable, in addition, any connection method that can meet the needs can also be used.

Finally, it should be noted that obviously, the above-mentioned embodiments are only examples for clearly illustrating the present invention, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description.
