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 includes a body, a front wheel and a rear wheel arranged at the bottom of the body, and an anti-overturning device; the anti-overturning device includes a hook assembly and a brake assembly; the hook assembly includes a rotating shaft, which is arranged at the front end of the rotating shaft The hook, the rotating shaft is installed on the body; the brake assembly includes a pedal for the pedal, a brake block for preventing the front wheel from moving backward, and a linkage mechanism for realizing the linkage between the pedal and the brake block. The linkage mechanism is installed on the body and the linkage mechanism is movably connected with the pedal and the brake block respectively. The hook assembly also includes a locking mechanism for limiting the rotation angle of the rotating shaft. The linkage mechanism is a multi-link mechanism. The invention can realize the firm connection with the switch cabinet, and can realize the braking well, so as to avoid the overturning accident in the process of pulling out the switch, ensure the safety of personnel, and improve the working efficiency.

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...
