Problems solved by technology

First of all, more maintenance personnel are needed, and the site space is limited, which is very inconvenient; when multiple people cooperate to lift heavy objects, if the force is not coordinated enough, there is a risk of secondary damage to the high-voltage vacuum circuit breaker; it is easy for maintenance personnel Injuries such as scratches, extrusion, and falling injuries; in addition, when installing high-voltage vacuum circuit breakers, it is not easy to accurately align them with the installation holes on the power distribution cabinet, which affects work efficiency

Embodiment 1

[0029] Please refer to Figure 1 to Figure 3 , this embodiment proposes a movable special platform for loading and unloading high-voltage vacuum circuit breakers, which includes a first bracket 1, a second bracket 2 slidably installed on the first bracket 1 in the vertical direction, and a second bracket 2 installed on the first bracket 1. The wheels 3 at the bottom of the second support 2 and the installation frame 4 installed on the top of the second support 2 are slid in the horizontal direction. The first bracket 1 plays the role of supporting the whole platform, and the second bracket 2 is slidably arranged on the first bracket 1 to adjust the height of the whole platform. During specific implementation, the first bracket 1 The sliding between the second bracket 1 can be set as a sliding connection between a plurality of sliding rods and a sleeve, or it can be a sliding connection between a sliding groove and a sliding rail. The wheels 3 are used to adjust the position o...

Embodiment 2

[0044] This embodiment is an improvement based on embodiment 1. The difference from embodiment 1 lies in the locking device 5, and the rest of the content disclosed in embodiment 1 can be used, and the same parts will not be repeated.

[0045] In this example, please refer to Figure 4 , the locking device 5 is an elastic rope, and the elastic rope is configured to fix the high-voltage vacuum circuit breaker on the installation frame 4 . During specific implementation, hooks are provided at both ends of the elastic rope, and the elastic rope is bypassed by the mounting frame 4 and the high-voltage vacuum circuit breaker on the mounting frame 4 during use. The two hooks can be hooked to each other, or both hooks can be hung together onto the mounting bracket 4. The high-voltage vacuum circuit breaker on the installation frame 4 is fixed by using the elastic rope, which can reduce the volume of the components on the entire installation frame 4, facilitate the insertion of the i...

Abstract

The invention discloses a movable special platform for loading and unloading high-voltage vacuum circuit breakers, which includes a first bracket, a second bracket slidingly installed on the first bracket along the vertical direction, and wheels installed at the bottom of the second bracket 1. A mounting bracket installed horizontally on the top of the second bracket; the second bracket is located above the first bracket; the mounting bracket is provided with a locking device for locking the high-voltage vacuum circuit breaker. The invention can facilitate the installation and disassembly of the high-voltage vacuum circuit breaker.

Description

technical field [0001] The invention relates to the technical field of loading and unloading tools for high-voltage vacuum circuit breakers, in particular to a movable special platform for loading and unloading high-voltage vacuum circuit breakers. Background technique [0002] The high-voltage vacuum circuit breaker is the core component of the substation. It has a fairly complete arc-extinguishing structure and sufficient current-breaking capacity. It can not only cut off or close the no-load current and load current in the high-voltage circuit, but also protect it through the relay when the system fails. The function of the device is to cut off the overload current and short-circuit current. The main structure of the high-voltage vacuum circuit breaker includes a diversion part, an arc extinguishing part, an insulating part and an operating mechanism part. During the long-term operation of the power transformation and distribution system, there will be failures such as s...
