[0002] Railway transportation is a mode of land transportation in which locomotives pull train vehicles on two parallel tracks. During the construction of the railway, large-scale track maintenance machinery is used for construction. However, during the construction process, workers are often close to the machinery, which seriously threatens the safety of the workers.
[0003] For example, a Chinese utility model patent (CN218436735U) discloses a safety distance warning device for large railway maintenance machinery construction, which records: "It includes a first warning plate, the inner cavity of the first warning plate is provided with an adjustment mechanism, the top of the first warning plate is provided with a lighting mechanism, the adjustment mechanism includes a second warning plate, the number of the second warning plates is two, the second warning plate is slidably connected to the inner cavity of the first warning plate, one side of the second warning plate is fixedly connected to a baffle, the lighting mechanism includes a box body, the box body is fixedly connected to the top of the first warning plate, the inner wall of the box body is slidably connected to a lamp tube, the number of the lamp tubes is two, and the top of the lamp tube is fixedly connected to a lamp holder."
