Adjustable type transport dolly and application method therefor

Abstract

The invention provides an adjustable type transport dolly comprising a support plate, a center of the support plate is provided with a height-adjustable main support assembly, two ends of the support plate are folded upward, folded side walls are provided with height-adjustable auxiliary support assemblies, space for an arc-extinguishing chamber used for supporting a circuit breaker is formed among the main support assembly and the auxiliary support assemblies arranged at two sides, and a bottom part of the support plate is provided with universal wheels. The invention also provides an application method for the adjustable type transport dolly, the arc-extinguishing chamber is supported by the main support assembly which is placed below the same, the arc-extinguishing chamber is supported by the auxiliary support assemblies that are arranged around the same, the arc-extinguishing chamber can be prevented from overturning leftward or rightward during slight slide in transport processes, height of the main support assembly and the auxiliary support assemblies is adjustable, the dolly can move conveniently via universal wheel design, the arc-extinguishing chamber is transported into a circuit breaker shell body, height of the dolly is adjusted, the dolly is moved to a suitable position, and the arc-extinguishing chamber can be installed. The dolly is simple in structure, convenient in application and reliable in performance.

Description

technical field [0001] The invention relates to a transport trolley, in particular to an adjustable transport trolley for transporting the arc extinguishing chamber of a horizontal circuit breaker into the shell and adjusting to the required height to facilitate the installation of the arc extinguishing chamber. Background technique [0002] At present, most 220kV GIS circuit breakers are of horizontal structure. After the arc extinguishing chamber is assembled, it needs to be put into the circuit breaker housing horizontally, and it cannot be hoisted at this time. However, when the arc extinguishing chamber is assembled, it needs to be lifted to a certain height and fixed with the circuit breaker housing. [0003] In order to solve the above problems, there is a method of using rubber pads as temporary support in the industry. This method is not easy to operate, and improper operation may easily cause damage to the arc extinguishing chamber. There is also a method of using...

Problems solved by technology

[0003] In order to solve the above problems, there is a method of using rubber pads as temporary support in the industry. This method is not easy to operate, and improper operation may easily cause damage to the arc extinguishing chamber.

There is also a method of using a fixed transport trolley, but the height of the trolley cannot be adjusted, which is not conducive to the installation of the arc extinguishing chamber. At the same time, the fixed trolley has no auxiliary support, and the arc extinguishing chamber is easy to dump during transportation.
