Technical Field
The invention belongs to the technical field of railway locomotive maintenance equipment, and particularly relates to a heavy-duty railway locomotive turntable.
Background
Railway transportation plays an important role in the economic development of China. The railway locomotive is the power for traction train operation, and because of curves of railway lines, uneven abrasion of wheel rims and treads on two sides of a bogie of the railway locomotive can be caused in the process of running the railway locomotive along the railway lines, so that the potential safety hazard caused by excessive eccentric abrasion on the running of the railway locomotive is reduced, and the railway locomotive needs to be subjected to regular turning and reversing operation, so that the abrasion of the wheel rims and the treads on the two sides is basically consistent.
The traditional devices for the turn-around reversing operation are "bulb wires", "delta wires". The bulb line and the triangular line are paved with curved tracks on the ground, and the railway locomotive walks on the curved tracks to complete turning (also called reversing) operation according to the operation specification. With the development of technology, a locomotive turntable is a device which is arranged in a circular pit and can rotate around the center of the pit, and a track for the locomotive to walk is arranged on the upper surface of the locomotive turntable. The railway locomotive is driven onto the turntable, and the turntable rotates 180 degrees to finish the turning (reversing) operation of the locomotive.
Locomotive wheeling discs have many advantages over "bulb lines" and "delta lines": the manufacturing cost of equipment is saved, the occupied area and the civil engineering construction cost are saved, and the operation procedure time is reduced. With the further development of economy and technology in China, railway transportation is developed towards high speed and heavy load, more duplex heavy load locomotives are needed, the duplex heavy load locomotives are heavy in weight and longer in vehicle body, and the turntable in the traditional structural form can cause the problems of high manufacturing cost, deep foundation pit, high investment cost and the like.
