Electric cable collecting and releasing device with braking function

Abstract

The invention discloses an electric cable collecting and releasing device with a braking function. The device comprises a left bracket, a right bracket, a base and a wire winding cylinder; the left bracket and the right bracket are fixed on the left and right sides of the base; the wire winding cylinder is arranged between the left bracket and the right bracket; wire baffle plates are fixed at theleft and right ends of the wire winding cylinder; a rotating shaft is fixed at the middle part of the wire baffle plate at the left end of the wire winding cylinder; the left end of the rotating shaft is connected with a transmission; the transmission is connected with a driving motor; a rotating tube is fixed at the middle part of the wire baffle plate at the right end of the wire winding cylinder; an electric extension cylinder is arranged on the right side of the right bracket; a pressing plate is arranged at the end part of a piston rod of the electric extension cylinder in the wire winding cylinder; a second braking pad is arranged on the left side of the pressing plate; fixed plates are arranged on the left and right sides in the wire winding cylinder; and first braking pads corresponding to the second braking pads are arranged on the right side of the fixed plate on the right side in the wire winding cylinder. The device is high in flexibility and stability, excellent in cablecollecting and releasing effect, capable of quickly braking and high in practicability.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a power cable retracting device with a braking function. Background technique [0002] With the development of the power system, some power lines will need to increase the voltage level and expand capacity, and the recycling and laying of power cables is a frequent work. Power cables are used to transmit and distribute electric energy. They are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. The existing cable retracting device is flexible and has poor stability. The cables are mostly concentrated in the middle of the winding drum during work, which affects the uniformity of cable winding. When the cable is wound, several people are required to work ...

AI Technical Summary

Problems solved by technology

The existing cable retracting device is flexible and has poor stability. The cables are mostly concentrated in the middle of the winding drum during work, which affects the uniformity of cable winding. When the cable is wound, several people are required to work together. It is not convenient for people in the distance to watch the speed of the winding and unwinding, which affects the coordination of the work and delays the progress of the work. In addition, the existing cable retracting device needs to be connected to the mains. Power supply, not convenient for outdoor work
