Description

Two-way cable pulley

technical field

The utility model belongs to the international patent classification H02G cable or electric wire or the installation technology or device of the combination of optical cable and cable or electric wire, in particular to a two-way cable pulley. the

Background technique

In the known technology, the 10kv transmission lines drawn from the substation are mainly cable outlets. Since many substation cable trenches have small space, and with the increase of lines laid into the cable trench, the wire diameter expands at the same time, and the weight of the cable increases. It is difficult to move the cable in the middle, and in many places, it can only be pulled by manpower, and it often requires the cooperation of multiple people to move, and the cable may cause wear and tear when dragged on the ground. the

Contents of the invention

The purpose of the utility model is to provide a two-way cable pulley, which is installed in the cable trench to facilitate cable laying. the

The measures to realize the purpose of the invention of the present utility model are: a pulley is installed on the support, and the support is composed of a vertical bar and a cross bar, the vertical bar is hinged to fix the pulley, and the end of the cross bar protrudes; the support is fixed on the cable trench wall by the protruding end of the cross bar superior. the

The utility model has the advantages of adopting the bracket pulley cooperation method to solve the problem of lifting and supporting the cable, the device is simple and practical, the friction force is small, the movement is convenient and quick, the labor intensity of cable laying is significantly reduced, the construction time is saved, the work efficiency is improved, and the Reduce cable wear and meet production safety needs. the

Description of drawings

Fig. 1 is a structural representation of the utility model

Reference signs include: cable trench wall 1, cable 2, bracket 3, pulley 4. the

Detailed ways

Below in conjunction with specific embodiment, illustrate:

Pulley 4 is installed on the support 3. the

Hinged pulley 4 above support 3. the

Support 3 is made of vertical bar and cross bar, and its vertical bar is hinged fixed pulley 4, and cross bar end protrudes, and support 3 is fixed on the cable trench wall 1 by its cross bar protruding end. the

The pulley 4 is hingedly suspended below the support 3 . the

The diameter of the pulley 4 is smaller than the two ends along the axial direction. the

When the utility model is installed and used, the bracket 3 is first installed on the cable trench wall 1 according to the construction design, then the pulley 4 is installed on the bracket 3, and finally the cable 2 is temporarily erected above the pulley 4, and the pulley 4 is lifted and supported from below. Pull the cable 2 from both ends of the cable 2. Under the action of friction, the pulley 4 rotates to move the cable 2 in both directions. When the cable 2 moves in place in the cable trench, move the cable 2 from the top of the pulley 4 and complete the positioning. Erection. the

The utility model is suitable for distributing and pulling power cables in the cable trench. The pulley has strong load-bearing capacity, fast construction and laying speed, convenient loading and unloading maintenance, low installation cost, and has the advantages of saving labor, reducing labor intensity, and being fast and safe. the

In the above embodiments, the security and installation technologies not described, as well as other necessary technologies related to the implementation, are based on existing technologies, and will not be listed in detail in sequence. the
