Description

A rolling rack for tensioning wires of transmission lines

technical field

The utility model relates to a rolling frame for a tensioning line of a power transmission line, which belongs to an auxiliary device used for a tensioning line of a power transmission line.

Background technique

During the installation of power transmission lines, it happens from time to time that conductors cross railways, highways, power lines, communication lines and various buildings. A lot of inconvenience. The traditional solution is to build a steel pipe spanning frame or fir pole frame, place the wires on the spanning frame, and use a tractor to pull the wires. This method solves the above problems to a certain extent. However, because the spanning frame is a fixed structure, the resistance is relatively large. On the one hand, the wires are prone to getting stuck in the process of advancing, which has potential safety hazards. It is also easy to wear the wires, making the smooth wires rough or even burrs, which reduces the transmission capacity of electric energy. , easy to cause corona accidents; on the other hand, the larger resistance also increases the mechanical load of the tractor, increasing the maintenance cost, energy consumption and labor intensity of the tractor.

Contents of the invention

The purpose of the utility model is to solve the technical problems of the existing spanning frame that are easy to hang and wear wires, large traction resistance and high maintenance cost, and provide a power transmission system that does not get stuck, does not wear wires, has small traction resistance and low maintenance cost. The line is tightened with a roller frame.

The technical scheme that the utility model takes for solving the problems of the technologies described above is:

A rolling frame for tensioning wires of transmission lines, including a main frame and a supporting frame installed in the middle of the main frame, wherein: it also includes a supporting roller and two vertical retaining rollers, and the supporting roller is installed in the middle of the supporting frame; the two vertical retaining The lower end of the roller is mounted on the main frame and located on both sides of the supporting roller.

The upper end of the vertical stop roller is equipped with a cross bar to prevent the wire from falling off.

The supporting roller and the vertical retaining roller are made of nylon insulating material.

Because the utility model adopts the above-mentioned technical scheme, rotatable supporting rollers and vertical retaining rollers are installed on the roller frame, and the supporting rollers and vertical retaining rollers are made of nylon insulating material with a smooth surface, which prevents the It reduces the traction resistance, prevents the wire from being worn by the spanning frame, improves the transmission capacity of the wire, and reduces the occurrence of corona accidents; at the same time, the rotatable supporting roller also reduces the load on the tractor and reduces the Maintenance costs are reduced, energy is saved, and the labor intensity of workers is reduced. If working in mountainous areas, a cross bar can also be installed on the upper end of the vertical roll to prevent the wire from detaching from the roll frame and improve the safety of work. Therefore, compared with the prior art, the utility model has the advantages of no hooking, no abrasion of wires, high wire transmission capacity, small tractor load, low maintenance cost, energy saving and low labor intensity of workers.
