Technical Field

The invention relates to the field of track maintenance vehicles, in particular to a track maintenance trolley capable of freely switching between a single track and double tracks.

Background

With the high-speed development of society and the continuous improvement of science and technology, the appearance of high-speed railways makes railway travel become the preferred travel mode of most people, railway transport is a land transport mode, a locomotive pulls a train vehicle to travel on two parallel rails, the traditional mode is steel wheel travel, but the generalized railway transport still includes the non-steel wheel travel mode of magnetic suspension trains, cable cars, cableways and the like, or called rail transport, the rails can provide extremely smooth and hard media to enable the train wheels to roll on the rails with the minimum friction force, so that people feel more comfortable on the rails, and can also save energy, if the configuration is proper, the railway transport can save five to seven times of energy compared with the road transport and carry the same weight, and the rails can evenly disperse the weight of the train, so that the loading capacity of the train is greatly improved, as is well known, the railway is formed by connecting the rails with each other through bolts, with the increase of time, the rail is sometimes damaged and loosened, and if the rail is not overhauled in time, the running of a train is greatly influenced, so that the rail needs to be overhauled regularly;

At present, most track maintenance trolleys can only be operated in one state of a single-track state or a double-track state, free switching cannot be carried out, and a single-track and double-track maintenance trolley capable of being freely switched is lacked.
