Problems solved by technology

[0003] The existing high-voltage circuit insulation is erected on the tower by setting up the hook point and pulling the cable on the ground. This method is subject to great limitations. For example, the space for pulling the wire is very large, so it can only be erected in a straight line, and it needs to be erected in sections when turning, etc.

Embodiment Construction

[0014] Decentralized power transmission line sheaves, such as figure 1 As shown, it includes a bracket 1 and a sheave 2 arranged on the bracket 1; a motor 3 is fixed on the bracket 1, and the output shaft of the motor 3 provides power to the sheave 2, and a partition 4 is arranged between the sheaves 2.

[0015] For the decentralized power transmission line sheave of aerial operation, promptly hang power sheave, its support 1 upper end establishes hanging plate 5.

[0016] For the decentralized power transmission line sheave on the ground, that is, the supporting power sheave, the lower end of the support 1 is provided with a foundation tower.

[0017] In this way, a decentralized power transmission line sheave is set on the tower, a supporting power sheave is set on the ground between the towers, the cable is placed on the hanging power sheave and the supporting power sheave, and the motor is started to make the sheave move towards the sheave at the same time. Power is provi...

Abstract

The invention discloses a power-dispersed cable erecting method and a power-dispersed power transmission cable sheave. The power-dispersed cable erecting method and the power-dispersed power transmission cable sheave have the advantages that the increasing of friction force of conveying process caused by the cable rolling on the crossing frame and being tangled with the crossing frame can be prevented, the conducting wire transmitting speed is increased, and the labor intensity is decreased in the cable erecting process; a motor is fixedly arranged on a bracket, the sheave is used as a driving wheel in the cable erecting process, and the movement power of the cable is dispersed just like each carriage of a rail car provides the power, so the labor is saved in the erecting process of the power transmission cable, and the cable erecting speed is increased.

Description

technical field [0001] The invention relates to a spanning frame for erecting transmission lines. Background technique [0002] Since the quality of the transmission wire, especially the high-voltage transmission wire itself, is large, and the two adjacent iron towers used to support the transmission wire have a large span, and there are charged objects, crops, trees, etc. between the two adjacent iron towers. Obstacles such as rivers, roads, buildings and structures are crossed, so erecting or dismantling transmission lines is a complex and difficult project. [0003] The existing high-voltage circuit insulation is erected in the way of erecting the mounting point on the tower and pulling the cable on the ground. This method is subject to great limitations. For example, the pulling site requires a large space, and it can only be erected in a straight line, and it needs to be erected in sections when turning. Contents of the invention [0004] Aiming at the deficiencies i...
