Abrasive belt grinding type all-type steel rail grinding device and method

Abstract

The invention discloses an abrasive belt grinding type all-type steel rail grinding device and method. The device comprises a rack, a power device, a transmission mechanism and a grinding mechanism. The grinding mechanism comprises an abrasive belt and a contact wheel. The mutual grinding action is generated between the abrasive belt and a steel rail under the grinding pressure directly applied bythe contact wheel to remove steel rail materials. The disclosed grinding method is achieved through the abrasive belt grinding type all-type steel rail grinding device. The grinding mechanism conducts the steel rail outline grinding motion in the steel rail surface vertical direction A, transverse direction B, longitudinal direction C and the rotation direction D with the longitudinal direction Cas the axis, and the contact state between the abrasive belt and the steel rail is changed in the steel rail surface rotation direction E with the vertical direction A as the axis. The method can beused for achieving disease removal and outline achieving of 50 kg / m, 60 kg / m and 75 kg / m positive line steel rails, branch cores, point rails and other turnout zone steel rails and groove profile rails. The abrasive belt grinding type all-type steel rail grinding device and method have the advantages that the grinding efficiency is high, the abrasive belt grinding type all-type steel rail grindingdevice and method adapt to multiple grinding work conditions, and the grinding tool cost is low.

Description

technical field [0001] The invention relates to the technical field of rail grinding, in particular to an abrasive belt grinding type all-type rail grinding device and a grinding method thereof. Background technique [0002] In recent years, with the rapid development of my country's rail transit industry, while the mileage of rail laying has increased year by year, diversified rail transit modes have shown a development trend that goes hand in hand, such as high-speed rail, ordinary rail, heavy-duty, light rail, subway, rail, etc. The turnout yard area and number of groups are also increasing. Repeated rolling of the wheelset for a long time will lead to various forms of diseases such as wavy wear, fat edge, falling block, fish scale pattern, joint collapse, etc. on the surface of the rail, especially the tip rail, fork core, and groove rail parts, replacement cost It is much higher than the main track, and if the disease in the turnout area is not dealt with in time, it wi...
