Description

A temporary hanging point fixing device for live replacement of V-shaped insulators on transmission lines

technical field

The utility model relates to an electric power operation tool, in particular to a temporary hanging point fixing device for live replacement of V-shaped insulators on transmission lines.

Background technique

Now in the process of replacing the insulator string or hanging point of the transmission line, it is often necessary to use a lifting device. The lifting device is set with a temporary hanging point. Use the lifting device to temporarily hook the insulator string on one side to the hanging point. After the replacement or maintenance is completed , use the thread structure of the lifting device to pull up the wire and then fix the wire on the insulator string. The commonly used lifting device is connected to the cross arm of the transmission tower through bolts. Since most of the cross arm is made of angle steel as a support frame, the wire The gravity is relatively large, it is easy to cause the lifting device to not form a vertical line well, often due to the gravity lifting process of the wire, it is easy to cause the lifting device to slip and the wire to jump.

Contents of the invention

In order to solve the problem of slippage and jumping of wires when electric maintenance personnel replace the V-shaped insulator string lifting device, the utility model discloses a temporary hanging point fixing device for live replacement of V-shaped insulators on transmission lines. The specific technical scheme is as follows:

A temporary hanging point fixing device for live replacement of V-shaped insulators on transmission lines, including a main body, characterized in that: the main body is provided with a hooking part, a load-bearing part and a fixing bolt, the hooking part is provided with an internal thread, and the fixing An external thread matching the internal thread is provided on the bolt, and the hooking portion is threadedly connected with the fixing bolt; the load-bearing portion includes two load-bearing arms, and grooves are provided on the load-bearing arms, and the grooves There are fixed plates on both sides;

Preferably, the fixing bolt is butterfly-shaped;

Preferably, the fixing plate is fixedly connected to the main body via bolts;

Preferably, the number of said fixing bolts is multiple;

Preferably, the main body is a T-shaped piece, and there are multiple load-bearing parts.

Compared with the prior art, the useful effect of the V-shaped insulator temporary hanging point fixing device for live replacement of the transmission line disclosed in the utility model is: the hooking part of the temporary hanging point device can be directly hooked on the angle steel of the crosspiece, because The hooking part is equivalent to a groove close to the thickness of the angle steel, and the hooking part has a certain width, which can make the hooking part closely connected with the angle steel. The fixed relationship of the cross-arm is more firm; the load-bearing part is provided with two load-bearing arms, and the load-bearing arm is provided with a groove, the operating rod of the lifting device is directly inserted into the groove, and fixed plates are set on both sides of the groove to effectively prevent the lifting device from sliding and The problem of wire jumping is solved, and the smooth lifting of the wire is realized. In addition, the main body of the utility model is not further processed, and the rigid structure features are more stable. Compared with the bolt connection between the cross arm and the lifting device in the prior art, it has a simple structure and convenient operation.

The main body is a T-shaped piece, and there are multiple load-bearing parts. The hooking part is set at one end of the upper arm of the T-shaped piece, and a load-bearing part is distributed between the other end and the lower arm, so as to meet the different installation methods of the angle steel on the cross arm. Realize one thing with multiple functions; the fixing bolts are butterfly-shaped, which is easier to disassemble, and no other tools are allowed to be used directly, which brings great convenience to workers working at heights; the fixing plate is fixedly connected with the load-bearing arm bolts to ensure the convenient disassembly of the fixing block; There are multiple fixing bolts, which can effectively increase the stability of the hook portion and the cross-arm angle steel.

To sum up, the utility model has the advantages of simple structure, convenient operation and reliable performance, and is more suitable for existing equipment.
