Embodiment Construction

[0029] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings. A specific embodiment of a lifting trolley of the present invention, such as Figure 1 to Figure 3 As shown, including bracket 1, bracket 1 is as Figure 4-6 The shown includes a base 11 and a vertical guide rail 12 that is arranged on the base 11 and extends along the up and down direction. The vertical guide rail 12 is a single guide rail, which can reduce the weight and volume of the bracket. The lifting trolley also includes up and down guiding movement The hoisting frame 3 set on the vertical guide rail 12 and the driving mechanism 2 arranged on the support 1 for hoisting and connecting with the hoisting frame 3 to lift the hoisting frame 3 . The section of the vertical guide rail 12 is an arrow-shaped structure 8, such as Figure 6 and Figure 13 As shown, the arrow-shaped structure 8 includes a head 81 and a tail 82. The front end of the head 81 ...

Abstract

The invention relates to a hoisting frame used for dismounting and mounting of a breaker and a hoisting trolley using the same. The hoisting frame comprises a hoisting frame body. A hoisting structure capable of moving relatively and used for being connected with the breaker to be dismounted and mounted so as to hoist the breaker and a connecting structure used for being connected with a driving mechanism used for driving the hoisting frame to move up and down are arranged on the hoisting frame body. When the breaker needs to be maintained, detected and replaced, the hoisting structure is connected with the breaker to be dismounted and mounted, the driving mechanism is used for driving the hoisting frame to move up and down through the connecting structure to achieve ascent and descent of the breaker, and the breaker in a switch cabinet can be taken out of the switch cabinet conveniently and safely with less effort and put back into the switch cabinet. Compared with the prior art, the problems of personal injury accidents and breaker damage caused by dismounting and mounting breakers manually are avoided.

Description

technical field [0001] The invention relates to the technical field of maintenance equipment in the electric power industry, in particular to a lifting frame for disassembling and assembling a circuit breaker and a lifting trolley using the lifting frame. Background technique [0002] Low-voltage switchgear is a common equipment in the power system. This kind of switchgear is often equipped with a drawer-type universal circuit breaker. When the circuit breaker needs to be maintained, repaired or replaced, it is often disassembled by manpower. Heavy, manual disassembly and assembly are prone to personal injury accidents or the drawer-type universal circuit breaker falls on the ground during disassembly and assembly, causing damage to the circuit breaker. Contents of the invention [0003] The purpose of the present invention is to provide a lifting frame for disassembling and assembling a circuit breaker to solve the problems of personal injury and damage to the circuit bre...
