Manual traction aid for cable pay-off

Abstract

The invention provides a cable laying manual traction auxiliary tool comprising a handle, a support transverse plate, an upper compacting device, and a lower support device. The handle is hinged to one end portion of the support transverse plate. A threaded through hole is disposed on the center of the support transverse plate. A threaded rod in the upper compacting device is sleeved by the threaded through hole. An inverted-T-shaped connection rod in the lower support device is disposed on one end of the support transverse plate and is located under the handle. The cable laying manual traction auxiliary tool is simple in structure and easy to carry. The upper compacting device and the lower support device may not only clamp a cable firmly in a used process, but also fundamentally eliminate a torsion problem in a manual cable laying process.

Description

technical field [0001] The invention relates to the field of power supply construction, in particular to a manual traction auxiliary tool for cable pay-off. Background technique [0002] With the continuous development of my country's economy, the application range of power equipment is becoming wider and wider. Cable laying work is an indispensable part of power transmission. In the construction of some large-scale power facilities, the use of cables and laying work are very large. . At present, when laying cables in the power system, there are mainly two methods, one is to use a crane to pay off the wires, and the other is to rely on the cable pay-off frame to place the cable reel on a rotatable pay-off frame, and manually realize the release. Wire. Using a crane to lay out the wires, due to the environmental constraints of the laying ground, in some places it is impossible to implement the crane to lay out the wires, and only manual wires can be used. In the actual opera...

This payoff eliminates the twisting force phenomenon of the cable to a certain extent, but when the connecting rod and the cable form an angle of 90°, the rotating shaft cannot be rotated, so that the twisting force generated by the rotation of the cable itself cannot be eliminated. The handle in the wire harness is inconvenient to use when laying cables, because the handle is a straight rod. When laying, there needs to be enough friction between the palm and the handle to pull the cable. For some users with small arm strength , unable to hold the handle to pull the cable
