Rail collection guidance and rail pushing trolley and long steel rail transport train set

The invention provides a rail collection guidance and rail pushing trolley and a long steel rail transport train set. The rail collection guidance and rail pushing trolley comprises a trolley body and telescopic arm assemblies; each telescopic arm assembly comprises a telescopic arm body, a sliding arm which is arranged outside the telescopic arm body in a sleeving mode and a first hydraulic cylinder used for driving the telescopic arm body to move in the axial direction of the sliding arm; the two sides of each sliding arm are supported by the trolley body through a first strutting piece and a second strutting piece; a clamp used for clamping steel rails is fixedly connected with the bottom end of each telescopic arm body. According to the rail collection guidance and rail pushing trolley and the long steel rail transport train set, each clamp can be driven to move up and down through the stretching and shortening of a piston rod of the corresponding first hydraulic cylinder; due to the fact that the volume of the hydraulic cylinders is smaller, the carrying capacity is stronger, the reliability is stronger, large-stroke lifting and dropping can be completed within a vehicle limit range, the safety and the efficiency are improved, and the working environment is improved.
