Embodiment Construction
[0040] 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 bottom frame 11 and a vertical guide rail 12 arranged on the bottom frame 11 and extending along the up and down direction. The vertical guide rail 12 is a single guide rail, which can reduce the weight of the bracket and reduce its volume. The lifting trolley also includes an up and down The guide moves the lifting frame 3 which is set on the vertical guide rail 12 and the drive mechanism 2 which is arranged on the support 1 and is used to lift and connect with the lifting frame 3 to lift the lifting 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 ...

The invention relates to a hoisting frame for breaker dismounting, a support and a hoisting trolley. The hoisting frame comprises a hoisting frame body. A hoisting structure which is used for being connected with a breaker to be dismounted to hoist the breaker is arranged on the hoisting frame body. The hoisting frame further comprises a guiding mechanism being in up-down guiding movement fit with a vertical guide rail arranged on the support. A connecting structure used for being connected with a driving mechanism is arranged on the hoisting frame body, and the driving mechanism is used for driving the hoisting frame to move up and down. When the breaker needs to be maintained or detected or replaced, the hoisting structure and the breaker to be dismounted are connected, and the driving mechanism drives the hoisting frame to move up and down through the connecting structure, so that rising and falling of the breaker are achieved. By the adoption of the hoisting trolley, the breaker in a switch cabinet can be taken out of the switch cabinet conveniently and effortlessly and falls onto ground, and meanwhile, the breaker can also be lifted from the ground and placed back into the switch cabinet. Compared with the prior art, the problem that personal injury accidents and breaker damage are caused by manual dismounting of the breaker is solved.
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, a bracket using the lifting frame, and a lifting trolley. 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...
