Description

Technical Field

[0001] The invention belongs to the field of cable bending, and in particular relates to a portable overhead lead bending tool. Background Art

[0002] At present, in the non-stop connection operation of 10kV overhead lines, it is necessary to connect a certain length of overhead lead wire (10kV steel core aluminum stranded wire) to the conductor through a parallel groove clamp. The parallel groove clamp is a connection hardware that cannot bear force. It is necessary to use external force to bend one end of the overhead lead wire into a certain arc so that the direction of the overhead lead wire can be effectively changed. This is called overhead lead wire bending.

[0003] As people's requirements for power supply reliability become higher and higher, non-stop operations are becoming more and more popular, and the corresponding help in "bending" overhead wires has naturally increased.

[0004] As the capacity of distribution networks continues to increase, the wire diameter of 10kV overhead lines is getting larger and larger, up to 240MM at most, making manual bending more difficult. Coupled with the influence of factors such as the small working space, the seemingly simple operation of "bending leads" often requires too much physical strength from the operators, and may not necessarily produce the desired curvature.

[0005] In traditional overhead wire bending, the operator often estimates the bending length and curve in advance, and uses both hands and other parts of the body, or two or more people to bend the overhead wire into a certain curvature, and then use an aerial work vehicle to complete the subsequent work. This is very labor-intensive, labor-intensive, and inefficient, and cannot meet the needs of overhead wire construction.

[0006] Therefore, we propose a portable overhead lead bending tool to solve the above problems. Summary of the invention

[0007] Aiming at the problem that manual bending of overhead lead wires is time-consuming and labor-intensive, and the bending effect is unsatisfactory, the present invention provides a portable overhead lead wire bending tool.

[0008] The solution adopted by the present invention to solve the technical problem is: a portable overhead lead bending tool, comprising a base, an electric cylinder, a support part, a bending mechanism, a conical stopper, a guide rod and a fixing part, wherein the electric cylinder is located on the top of the base, the fixing part is sleeved on the outside of the electric cylinder and is detachably connected to the base to fix the electric cylinder on the base; The bending mechanism includes a fixed block and two bending heads. The fixed block is fixedly mounted on the telescopic end of the electric cylinder. Adjusting pieces are respectively arranged at the opposite ends of the two bending heads. The adjusting pieces are connected to the fixed block and can adjust the distance between the two bending heads. The support part is welded and fixed on the right end of the base, the guide rod is welded and fixed on the top of the support part, and the conical stopper is sleeved on the guide rod and can move up and down along the guide rod.

[0009] Preferably, a lifting portion for supporting the cable is provided at the end of the bending head.

[0010] Preferably, the support portion includes a support seat and a connecting seat, the connecting seat is welded and fixed to the right end of the base, the support seat is welded and fixed to the bottom of the connecting seat, and its right end extends to the bottom of the conical stopper.

[0011] Preferably, ribs are respectively provided on the front and rear sides of the connecting seat, and the ribs are welded and fixed between the base and the connecting seat.

[0012] Preferably, the fixing member is a U-shaped screw, and both ends of the U-shaped screw respectively pass through through holes reserved on the base and are respectively threadedly connected to two nuts.

[0013] Preferably, a handle is welded and fixed to the top of the U-shaped screw.

[0014] Preferably, two slots are provided in the fixing block, and the two slots are arranged one above and one below. A threaded hole one is provided on the top of the fixing block, and the threaded hole one is connected to the two slots above and below.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1.

The two ends of the U-shaped screws 21 respectively pass through the through holes reserved on the base 1 and are respectively threadedly connected with two nuts 22 to fix the electric cylinder 3 on the base 1. Conversely, by unscrewing the nuts 22, the U-shaped screws 21 can be removed to repair or replace the electric cylinder 3.

[0024] A handle 4 is welded and fixed to the top of the U-shaped screw 21, so that the user can hold the handle 4 to carry and use the device.

[0025] The bending mechanism includes a fixed block 71 and two bending heads 72. The fixed block 71 is fixedly installed on the telescopic end of the electric cylinder 3. Two slots 77 are provided in the fixed block 71. The two slots 77 are arranged one above and one below.
