Portable electric operation tool for high-voltage switch cabinet handcart

Abstract

A portable electric operation tool for a high-voltage switch cabinet handcart comprises a shell of a symmetrical double-handle structure, an energy storage battery, a motor, a speed reducer and an output shaft are installed in the shell, and the motor drives the output shaft to rotate through the speed reducer under the energy supply of the energy storage battery; the speed reducer consists of three stages of speed reducing mechanisms which are connected in series, namely a fixed shaft gear speed reducing mechanism, a harmonic gear speed reducing mechanism and a planetary gear speed reducing mechanism in sequence, wherein the input end of the fixed shaft gear speed reducing mechanism is connected with the motor, and the output end of the planetary gear speed reducing mechanism is connectedwith the output shaft. According to the invention, the high-voltage switch cabinet handcart can move rapidly, rapid insertion and separation of the moving contact and the static contact are realized,and the moving contact and the static contact are prevented from being damaged due to long-time discharge. In addition, the speed reducing mechanism is integrally designed, and the occupied size of the speed reducing mechanism is reduced to the maximum extent. The device has the advantages of being labor-saving in operation, high in efficiency, large in electricity storage capacity and convenientto carry.

Description

technical field [0001] The invention relates to the technical field of power tools, in particular to a portable electric operating tool for a handcart of a high-voltage switch cabinet. Background technique [0002] The high-voltage switchgear is composed of a circuit breaker room, a busbar room, and a cable room. There are upper and lower static contacts in the busbar room and cable room, and upper and lower moving contacts on the handcart. The handcart is located on the track of the circuit breaker room, and the handcart is moved on the track by the rotation of the screw to achieve dynamic and static contact. Insertion and separation of contacts. [0003] At present, the rotation of the screw is realized by manually turning the handle. Since the stroke of the handcart is long and the handle is not a force couple structure, it is not only laborious to manually turn the handle, but also the force is uneven, and the handle is prone to fall off.

AI Technical Summary

Problems solved by technology

[0003] At present, the rotation of the screw is realized by manually turning the handle. Since the stroke of the handcart is long, the handle is not a force couple structure. Therefore, it is not only laborious to manually turn the handle, but also the force is uneven, and the handle is prone to fall off.

More importantly, the artificial shaking speed is slow

When the moving and static contacts are about to touch, there will be inter-electrode discharge between the moving and static contacts. Due to the slow speed of manual shaking, the long-term inter-electrode discharge will damage the moving and static contacts due to burns, causing the equipment to fail to work normally.
