Steel rail profiling grinding machine

Abstract

The invention provides a steel rail profiling grinding machine. The steel rail profiling grinding machinecomprises a rack which is used for connecting or arranging all devices of the steel rail profiling grinding machine or providing support for the devices, an electric power supply device which is usedfor supplying electric power to a device in the steel rail profiling grinding machine, an abrasive belt grinding device which is used for grinding the steel rail, is connected to the rack and comprises a driving wheel, a contact wheel and an abrasive belt, a deflection device which is used for driving the steel rail profiling grinding machine to deflect around the steel rail and comprises two limiting wheels coaxially arranged and havingdifferent diameters,and apower supply device which is used for supplying power to a driving wheel of the abrasive belt grinding device. The abrasive belt is adopted as a grinding tool, the abrasive belt and a steel rail are in flexible contact during grinding operation due to the characteristics of the contact wheel rubber layer and the abrasive belt, the influence of vibration of a grinding machine on the surface layer of the steel rail is reduced, and the grinding quality is improved; meanwhile, two-section deflection is arranged, so that the whole profile range of the steel rail can be ground; a direct-current motor and a battery are used for driving, the weight is light, noise is low, and environmental friendliness is achieved.

Description

technical field [0001] The invention relates to the technical field of railway maintenance machinery, in particular to a rail profiling grinding machine. Background technique [0002] According to the inspection requirements of line rails, the size and surface smoothness of rail seams after welding treatment are generally high, so the weld seam (or welded part) needs to be polished. In the prior art, a rail grinding wheel weld seam grinder is used to grind the weld seam. But the existing rail grinding wheel weld seam grinder has the following disadvantages: (1) internal combustion engine is used as the drive, and the vibration is large during the grinding process, which affects the grinding quality of the rail surface; at the same time, the noise is large, the dust is large, and the exhaust emission is serious, resulting in environmental pollution and serious Affect the health of workers, and (2) adopt emery wheel to grind, and the grinding content is monotonous, sparks spl...

Problems solved by technology

But the existing rail grinding wheel weld seam grinder has the following disadvantages: (1) internal combustion engine is used as the drive, and the vibration is large during the grinding process, which affects the grinding quality of the rail surface; at the same time, the noise is large, the dust is large, and the exhaust emission is serious, resulting in environmental pollution and serious Affect the health of workers, and (2) use grinding wheels for grinding, the grinding content is monotonous, sparks splash around, and the safety is poor

[0003] In addition, due to the existence of the weld seam, the existing grinding machine easily causes the guide wheel to jump when walking through the weld seam and its vicinity (because the weld seam is not smooth), thereby causing the grinding surface to be uneven and more likely to cause damage to the grinding wheel. thereby affecting the safety of operators
