Electric tool for cable laying

Abstract

The invention discloses an electric tool for cable laying. The tool comprises a bottom frame which is provided with a walking mechanism; a vertical lifting mechanism which is installed on the bottom frame and comprises a lifting motor, a lifting lead screw, a lifting nut and a limiting guide rail, wherein the output end of the lifting motor is connected with the lifting lead screw to drive the lifting lead screw to rotate, the lifting lead screw is in transmission fit with the lifting nut, and the lifting nut is installed in the limiting guide rail to limit vertical movement; and a horizontal telescopic mechanism which is fixedly connected with the lifting nut and comprises a telescopic motor and a telescopic supporting arm, wherein the output end of the telescopic motor is connected with the telescopic supporting arm to drive the telescopic supporting arm to stretch out and draw back, and the telescopic supporting arm is used for bearing a cable and moving the cable to an installation position. The walking mechanism is arranged on the bottom frame, self-walking in the tunnel can be achieved, the vertical lifting mechanism lifts the cable to the designated height through lead screw transmission, the cable is pushed in the horizontal direction in combination with the horizontal telescopic mechanism, operation is convenient, time and labor are saved, and use is stable and safe.

Description

technical field [0001] The invention relates to the field of cable auxiliary installation equipment, in particular to an electric tool for cable laying. Background technique [0002] In recent years, with the continuous increase of the power load of the urban power grid and the increasingly tense line corridors, cable tunnels are widely used in large and medium-sized cities for power transmission, and the length of cables and cable tunnels continues to increase. under tremendous pressure. Research and construction of large-capacity cable lines has become an important issue that my country's large-scale urban power grids must face. Due to the high voltage level and large transmission capacity, there are higher requirements for the laying quality of ultra-high voltage cable tunnels, which have a great impact on the safe and stable operation of the system. Technical problems need to be solved urgently. At present, in the long section of high-voltage cable laying projects in tu...

AI Technical Summary

Problems solved by technology

Due to the high voltage level and large transmission capacity, there are higher requirements for the laying quality of ultra-high voltage cable tunnels, which have a great impact on the safe and stable operation of the system. Technical problems need to be solved urgently. At present, in the long section of high-voltage cable laying projects in tunnels in my country, the current scheme for cable racking is relatively simple, and most of them are carried out by manual moving and racking, which requires a lot of manpower and material resources.
