In electrical installation engineering, channel steel is widely used as a base of equipment such as a disconnecting link, a voltage transformer, a current transformer, a secondary screen cabinet and the like. However, the steel is very easy to be extruded and deformed during the transportation, loading and unloading of the steel channels. If the straightening is not carried out again before the use, the subsequent bridge and the installation quality of the disconnecting link are directly influenced. The use quantity of channel steel is big in the construction of large-scale transformer substation, and channel steel straightening efficiency and technology level have huge influence to the construction quality of engineering and up to standard input. According to the traditional straightening method, the stay wire is compared with channel steel, after uneven points are found, a big hammer is used for beating one by one until the whole channel steel is straightened. However, the straightening method is slow in straightening speed, consumes a large amount of manpower, and increases the straightening processing cost of the channel steel. In addition, by comparing the straightening point with the non-straightening point, it can be found that the galvanized layer of the struck point (namely, the straightening point) falls off in the process of hammering the straightening channel steel, and the galvanized layer near the struck point is loosened and easily falls off, so that the galvanized layer of the channel steel needs to be reprocessed.
