Problems solved by technology

In order to facilitate the transfer of circuit breakers, the trolley is often placed horizontally or leaning against the switch cabinet. Push rods and universal wheels are installed on the trolley. No matter how the circuit breaker transfer trolley is placed, it will still occupy a lot of space around the switch cabinet. , if the circuit breaker transfer trolley interferes with the commissioning of the switchgear, it is often chosen to remove the circuit breaker trolley. During the removal process, the transfer trolley will inevitably collide or overturn, which will greatly shorten the service life of the transfer trolley. Furthermore, the circuit breaker transfer The absence of a fixed location for the trolley will also increase the search time for the circuit breaker transfer trolley, delaying the commissioning or maintenance of the switchgear

Embodiment 2

[0030] In embodiment two of the present invention:

[0031] The difference from Embodiment 1 is that an "L"-shaped connecting plate can also be provided on the base, and the connecting plate includes a horizontal plate for installing wheels and a vertical plate for fixed connection with the curved plate of the chute of the base. The plate is provided with a fixing pin for fixing the connecting plate on the curved plate of the chute. The curved plate of the chute is provided with a U-shaped groove for slidingly installing the vertical plate of the connecting plate. The two sides of the U-shaped groove are folded inward, and the wheel It can slide up along the U-shaped groove close to the workbench and slide down away from the workbench. The bottom of the groove is equipped with a lower fixing hole that allows the wheels to be installed on the small end of the base when the circuit breaker transfer trolley is in use and allows the circuit breaker to be transferred. When the trol...

Embodiment 3

[0032] In embodiment three of the present invention:

[0033] The difference from Embodiment 1 is that the base is provided with a slideway extending horizontally to the bottom of the base along the vertical direction of the side of the base, the slideway is an L-shaped slideway, and the slideway includes a vertical section installed on the side 1. The horizontal section installed on the bottom and the circular arc section connecting the horizontal section and the vertical section. Sliders for fixing the wheels are installed in the slideway. When the circuit breaker transfer trolley is in the retracted state, the wheels are installed on the slideway The horizontal section of the slideway is located at the lower end of the base; when the circuit breaker transfer trolley is in use, the wheels are installed on the vertical section of the slideway and located on both sides of the base through fixtures.

[0034] In other embodiments of the present invention: the lifting device can ...

Abstract

The present invention relates to a breaker transfer trolley. The breaker transfer trolley has a pack up state capable of packing up a workbench towards a pedestal and a usage state of rising the workbench from the pedestal and capable of transferring a breaker. Wheels are assembled on the pedestal in a swinging or guide movement manner and have the bottom surfaces having the farthest distances with a working surface of the workbench, and the movement stroke of swinging or guide movement of the wheels possesses a low-position state and a high-position state corresponding to the breaker transfer trolley in the usage state and the breaker transfer trolley in the pack up state. The wheels in the low-position state move to the lower end of the pedestal, and a maximum distance exists between the bottom surfaces and the working surface of the workbench. The wheels in the high-position state move to the two sides of the pedestal or in the pedestal, and the distance between the bottom surface and the working surface of the workbench is less than the maximum distance. The trolley is also equipped with the locking members of locking the wheels in the high-position state and the low-position state separately. According to the present invention, the overall height and the space occupied area of the breaker transfer trolley are reduced, and the breaker transfer trolley is convenient to place.

Description

technical field [0001] The invention relates to a circuit breaker transfer trolley. Background technique [0002] The circuit breaker transfer trolley is a tooling trolley that pulls out or pushes the circuit breaker in the removable switchgear into the circuit breaker room. Most of the circuit breaker transfer trolleys in the existing market are fixed shelves. When pushing into the circuit breaker room, you need to place the circuit breaker on the shelf of the transfer trolley, push the circuit breaker to the circuit breaker room by hand, if you want to pull out the circuit breaker, put the circuit breaker transfer trolley and the switchgear For docking, manually pull out the circuit breaker, and pull the circuit breaker to the circuit breaker transfer trolley through the movement of the rollers on the circuit breaker chassis, and then perform maintenance. [0003] At present, the base of the circuit breaker transfer trolley on the market is bulky, and it takes up a large ...
