Power cable bending machine

Abstract

The invention discloses a power cable bending machine, which comprises a gear box and an operation handle. The gear box comprises a main box body, a bottom cover, a rear cover, a movable stress bar, amain gear, a transmission shaft, an auxiliary gear and a linkage shaft, the main box body is detachably connected with the bottom cover and the rear cover, a rectangular vertical through hole II is formed in the center of the front wall of the main box body, fixed stress bars are symmetrically arranged on the left and right sides of the through hole II, the auxiliary gear is fixed to the linkageshaft, one end of the linkage shaft passes through the main box body, and the other end of the linkage shaft is connected with the bottom cover; one end of the movable stress bar is arranged in the main box body and connected with the linkage shaft in a threaded mode, and the other end of the movable stress bar passes through the through hole II; the main gear is fixed to the transmission shaft, one end of the transmission shaft passes through the rear cover, the main gear and the auxiliary gear are engaged vertically, and the operation handle is connected with the linkage shaft or the transmission shaft. According to the power cable bending machine, the structure is simple, force applying is light and convenient, the power cable bending machine can be probed into a connecting box for use,and is suitable for various internal space operation.

Description

technical field [0001] The invention relates to the field of power supply engineering, in particular to a power cable bender. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. In various engineering constructions, the laying and wiring of power cables are completed by professionals as key projects, and the wiring of cable terminals is a technical problem. . The wiring of power cable terminals is often carried out in the junction box, so the working space is small, the bending is difficult, and it is easy to cause damage to the cable core. At present, the operators usually put the cables into the junction box through the wire inlet, and then drag the cables out through the wiring operation port, and use the F-type wrench or other cable bending tools to complete the bending of the cables outside the junction box, and then Pull back the cable to complete the wiring of the cable cores in the junction box. During the period, ...

The wiring of power cable terminals is often carried out in the junction box, the working space is small, the bending is difficult, and it is easy to cause damage to the cable core

At present, the operators usually put the cables into the junction box through the wire inlet, and then drag the cables out through the wiring operation port, and use the F-type wrench or other cable bending tools to complete the bending of the cables outside the junction box, and then Pull back the cable to complete the wiring of the cable cores in the junction box. During the period, it is necessary to adjust the curvature many times due to inaccurate bending. The above steps are time-consuming and laborious, especially in the junction box with high explosion-proof requirements. The space is too small. The advanced cable bending tool cannot be used at all. During the internal implementation process, the operator will easily cause mechanical scratches when applying force, and will also damage the insulation layer of the cable core, reducing the insulation effect and causing accidents.
