Description

Rail unloading device Technical Field The application belongs to the technical field of railway line maintenance, and particularly relates to a rail unloading device. Background Rails are the main component of a railway track. Its function is to guide the wheels of the rolling stock to advance, bear the huge pressure of the wheels and transmit to the sleeper. The rails must provide a continuous, smooth, and least resistant rolling surface for the wheels. In electrified railway or automatic block section, the rail can also be used as a track circuit, and the long-term train running can cause the problems of rail abrasion, crack, abrasion, peeling and the like, so that the rail needs to be replaced after the damage is limited. In the past, the rail is replaced by adopting a crane to hang and unload, and because the power grid is arranged above the railway, the power grid is required to cut off and then lift so as to avoid electric shock, and during the rail unloading process, a transfer car, a shunting person, a contact net worker, a crane driver and other multiple kinds of work are required to hang and unload the rail in cooperation with the work, so that the whole process is complex and tedious, the unloading time is long, and the work maintenance efficiency is low.
