Problems solved by technology

However, after the Beijing-Shanghai high-speed railway was put into operation, the phenomenon of rail corrugation and elastic bar breaking showed that it was no longer sufficient to rely on conventional low-speed grinding trains for preventive grinding of high-speed railway rails. At the same time, most of the existing grinding vehicles It takes time to work in the skylight, which affects the operation. The position of the grinding device of the operation vehicle cannot be adjusted, causing the position of the grinding belt to deviate at the turning and climbing places; the grinding posture cannot be adjusted, and it is impossible to realize the full rail surface grinding of the rail; The grinding process is uncontrollable and has no records; there is no iron filings and spark collection system, which not only causes environmental pollution, but also easily leads to fire

Abstract

The invention discloses a high-speed grinding train for rails. The high-speed grinding train comprises a grinding operating train and grinding devices with grinding assemblies. Each grinding device further comprises a grinding frame, the grinding frame is a square frame, two U-shaped beams are opposite to each other and are integrally connected with each other by short crossbeams to form the square frame, two ends of each short crossbeam are connected with the U-shaped beams by hinge pins, the short crossbeams can slide up and down along the hinge pins, the two grinding assemblies of the grinding device are parallelly mounted in the grinding frame, two ends of each rotary frame are rotatably connected with the grinding frame, at least one end of each rotary frame is provided with a rotation driving device, the upper portion of the grinding frame is hinged with the bottom of a carriage of the grinding operating train by a lift cylinder, and support wheels are mounted on the lower portion of the grinding frame. The high-speed grinding train is high in stability, and can meet grinding requirements of various roads, skylight operation is omitted, a grinding procedure is controllable and adjustable, full surfaces of the rails can be ground, and the high-speed grinding train is safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of railway maintenance equipment, in particular to a rail high-speed grinding train used for preventive grinding of railway rails. Background technique [0002] Rail grinding is a main method to eliminate the wave wear of the rail and control the contact fatigue of the rail, and prevent the flaking, cracking and other diseases caused by contact fatigue. The main methods are corrective grinding, maintenance grinding and preventive grinding. For a long time, rail grinding has mainly been achieved by low-speed grinding trains and milling trains. However, after the Beijing-Shanghai high-speed railway was put into operation, the phenomenon of rail corrugation and elastic bar breaking showed that it was no longer sufficient to rely on conventional low-speed grinding trains for preventive grinding of high-speed railway rails. At the same time, most of the existing grinding vehicles It takes time to work in the sky...
