Open type abrasive belt steel rail grinding device

Abstract

The invention belongs to an open type abrasive belt steel rail grinding device in the maintenance machinery steel rail grinding field. The open type abrasive belt steel rail grinding device is composed of a traction device, a lifting device, a walking mechanism, an abrasive belt transmission mechanism, and an abrasive belt and steel rail contacting and pressing part, wherein the traction device, the lifting device and the walking mechanism are connected with an external grinding trolley, the walking mechanism is connected with the traction device and the lifting device, and the abrasive belt transmission mechanism makes contact with a trolley steel rail through the abrasive belt and steel rail contacting and pressing part. The open type abrasive belt steel rail grinding device has the advantages that abrasive belts make elastic contact with the steel rail, rigid collision between grinding wheels and the steel rail is avoided, and the abrasive belts belong to coating and grinding tools and can be effectively used in the grinding process; grinding units are simplified, the requirement for the control technology is lowered, and maintenance cost is reduced; the heat dissipation performance of the abrasive belts is good, the noise is low, the surface of the steel rail can not be burnt in the grinding process, the grinding tools can not be damaged in the grinding process, the grinding belts replace grinding wheels to conduct grinding in the maintenance stage of part of paths, and the open type abrasive belt steel rail grinding device is popularized to preventive grinding of an existing path.

Description

technical field [0001] The invention belongs to the field of rail grinding in road maintenance machinery, in particular to an open abrasive belt rail grinding device. Background technique [0002] At present, most of the rail grinding trolleys on the market use the consolidated abrasive wheel as the grinding tool. During the rail grinding operation, the grinding wheel and the rail are in rigid contact. To maintain sharp cutting performance, the requirements for grinding wheel formula and manufacturing process are relatively high. At the same time, rail grinding trains generally have dozens of grinding wheels working together at the same time, which requires high reliability of grinding wheels. From the perspective of grinding tools, domestically produced grinding wheels are still It cannot fully meet the requirements of rail grinding.

[0002] At present, most of the rail grinding trolleys on the market use the consolidated abrasive wheel as the grinding tool. During the rail grinding operation, the grinding wheel and the rail are in rigid contact. To maintain sharp cutting performance, the requirements for grinding wheel formula and manufacturing process are relatively high. At the same time, rail grinding trains generally have dozens of grinding wheels working together at the same time, which requires high reliability of grinding wheels. From the perspective of grinding tools, domestically produced grinding wheels are still It cannot fully meet the requirements of rail grinding. At present, rail grinding wheels basically rely on foreign imports, and as a consumable for grinding operations, they account for the main component of rail maintenance costs. The introduction of control systems and grinding wheels increases the cost of rail grinding.
