Problems solved by technology

At this stage, avoiding the overturning of the handcart platform is mainly realized by increasing the number of operators and dividing the work. This method increases the workload of the personnel, but it is difficult to completely guarantee that there will be no overturning accidents of the handcart platform

Embodiment 1

[0030] Embodiment 1: First define the direction: the handcart platform is pushed to the side of the switch cabinet and the switch is ready to be pulled out. For the handcart platform, the side close to the switch cabinet in the horizontal direction is defined as "front". One side is "rear", and the two directions perpendicular to "front" and "rear" are "left" and "right" respectively. Therefore, the switch cabinet is located in front of the handcart platform. When the switch is pulled out, the switch is pulled to move the right front and back, and is pulled out from the switch cabinet to the handcart platform.

[0031] as attached figure 1 As shown, a handcart platform includes a cuboid body 1 , wheels arranged at the bottom of the body 1 and an anti-overturning device, wherein the wheels include two front wheels 2 and two rear wheels 3 . The switchgear is located at figure 1 On the left side of the middle-hand car platform, that is, on the figure 1 The middle left correspo...

Abstract

The invention relates to a handcart platform, which comprises a body, front wheels and rear wheels arranged at the bottom of the body, and an anti-overturning device, and the anti-overturning device comprises a hook assembly and a brake assembly. The hook assembly comprises a rotating shaft and a hook arranged at the front end of the rotating shaft; the rotating shaft is rotationally mounted on the body; the brake assembly comprises a pedal used for being pedaled, a brake block used for preventing the front wheels from moving backwards and a linkage mechanism used for achieving linkage of thepedal and the brake block, and the linkage mechanism is installed on the body and movably connected with the pedal and the brake block. The hook assembly further comprises a locking mechanism used forlimiting the rotating angle of the rotating shaft. The linkage mechanism is a multi-connecting-rod mechanism. Firm connection with the switch cabinet can be realized, and braking can be well realized, so that an overturning accident in the process of pulling out the switch is avoided, the personnel safety is guaranteed, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the field of electric power operation auxiliary equipment, and in particular relates to a handcart platform used for overhauling switches. Background technique [0002] The central switchgear is the mainstream equipment in the 10kV switch at the present stage, and it is very commonly used. Before the switch is overhauled, the switch needs to be pulled out from the central switch cabinet to the handcart platform. The weight of the switch is generally large, and the weight is mainly distributed near the contacts, so the center of gravity of the switch is biased towards the front. When pulling out the switch, first push the handcart platform to the back of the middle-mounted switch cabinet, connect the handcart platform to the switch cabinet, and confirm that the handcart platform is firmly connected to the switch cabinet, and then the switch can be pulled out. [0003] However, the existing handcart platform has a simple struct...
