Problems solved by technology

Since there is no dedicated fast power cable pay-off device, it is not only troublesome to operate, time-consuming and labor-intensive, but also the hard cable pulled out is not straight, and it is not easy to use because it is not known how long the cable is actually released. The existing pay-off device needs to cut off the cable with the help of another pliers or cutting knife after the cable is unwound to the required length. Cutting after the cable is tensioned is not only laborious but also slow in cutting speed

Abstract

The invention discloses a power cable pay-off device, comprising a frame, a first support rack, a second support rack, a third support rack, a cable drum, a tensioning wheel set, a wire passing shaftand a walking wheel; the first support rack, the second support rack and the third support rack are orderly fixed on the frame; the cable drum is connected onto the first support rack in a rotating manner through a rotating shaft, the tensioning wheel set is connected onto the second support rack in a rotating manner, the wire passing shaft is connected to the third support rack in a rotating manner, and the walking wheel is arranged below the frame; the third support rack includes a supporting plate fixed on the frame, two side plates fixed on the supporting board, a central shaft fixedly connected between the two side plates, sensor probes arranged inside the side plates, and a counter disposed on the frame and connected with the sensor probes. The power cable pay-off device is characterized by simple structure, convenient operation and reliable operation; the power cable pay-off device can be widely applied in power cable laying operation, cable pay-off construction can be greatly facilitated, construction efficiency can be effectively improved, and labor intensity of construction workers can be lowered.

Description

technical field [0001] The invention relates to a power cable releaser. Background technique [0002] With the development of the power grid, the amount of cables in various distribution networks continues to increase, but the quality and efficiency of cable laying and laying have not been effectively resolved. Finally, it is necessary to use a crane to lift it for laying. This operation method not only requires great physical strength of the construction personnel, but also easily increases the torque of the cable itself or damages the cable insulation layer, thereby bringing hidden dangers to the safety of power supply in the future. The power supply line is mainly composed of various power control devices connected by various power supply cables. Among them, various power supply cables are also erected in the power control equipment, and such power supply cables can be roughly divided into hard cables and flexible cables in terms of material hardness. Soft cable means t...
