The invention relates to a large frequency converter shifting device and shifting method. The large frequency converter shifting device comprises a jacking frame, a wheel support and a wheel; two parallel jacking frame connecting plates are arranged at the front end of the jacking frame, first pin holes are formed in the jacking frame connecting plates, a threaded hole is formed in the upper surface of the rear end of the jacking frame, the lower surface is provided with a round hole, the threaded hole is provided with a bolt, and the round hole communicates with the threaded hole; and the upper end of the wheel support penetrates through the round hole, the upper surface of the wheel support abuts against the bolt, and the wheel support is connected with the wheel. The device and the method can be used for various working conditions, the use of large hoisting machinery is saved, and the advantages can be reflected especially in the situation that the use of the large hoisting machinery is limited; the device is simple, convenient to disassemble and easy to operate; and a set of devices can be reused, so that expenses of an enterprise is saved.
Description
technical field [0001] The invention relates to the field of frequency converters, in particular to a large-scale frequency converter shifting device and a shifting method. Background technique [0002] Due to the high-power inverter itself is heavy, and the space is often limited during installation, it is difficult for large-scale hoisting machinery to be used, and manual lifting is immobile, so it often makes it difficult to place the inverter in place. Therefore, there is an urgent need to develop a shifting device to solve the handling problem of high-power frequency converters. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned disadvantages in the prior art. [0004] In order to achieve the above purpose, in the first aspect, the embodiment of the present invention provides a large-scale inverter displacement device, including a jacking frame, a wheel bracket and a wheel; two parallel jacking frame connecting plat...
