Problems solved by technology

However, this solution has problems when the cutting amount changes suddenly, the tool life is reduced due to tool burns, and the cost of the tool is relatively high, which limits the work efficiency
High working speed and high noise
The collection rate of iron filings is high, but the heat is high, which is a great test for the dust collection device

Abstract

A flexible steel rail grinding device comprises an installation frame, a vertical plate, a supporting rod, a feeding mechanism, grinding units and a guide rail sliding block mechanism, and the feedingmechanism is connected with the guide rail sliding block mechanism. The guide rail sliding block mechanism comprises a sliding plate installed on the vertical plate in a sliding mode, and the slidingplate is further provided with a plurality of grinding units. Each grinding unit comprises a flexible polishing wheel, a driving device and a driving device accessory mechanism. A flexible steel railgrinding wagon comprises a wagon body, a cab is arranged at the front end of the wagon body, a mechanical and electric appliance room is arranged in the middle the wagon body, a dust collecting device is arranged at the rear end of the wagon body, a walking driving system and a plurality of grinding devices are arranged under the mechanical and electric appliance room, and the grinding devices are mounted in the bottom of the wagon body and used to grind a steel rail. According to the steel rail grinding device and the grinding wagon, the flexible grinding wheel is adopted, grinding head angle control and vertical feeding can be conducted, the grinding amount can be automatically controlled, tool abrasion can be automatically compensated, and grinding at all angles can be conducted on thesteel rail.

Description

technical field [0001] The invention belongs to the technical field of rail grinding, and in particular relates to a flexible rail grinding device and a rail grinding vehicle. Background technique [0002] In recent years, with the rapid development of rail transit, with the increasing speed, heavy load and departure frequency, the use of rails is deteriorating. Cross-sectional defects such as fatigue cracks, spalling, fat edge, etc. and longitudinal section defects such as wave wear are prone to occur on the surface of the rail. Changes in rail profile and smoothness have an important impact on driving safety, comfort and economy. In order to improve the wheel-rail relationship, prolong the life of the rail, and improve economy and safety, repairing the rail is a commonly used method at home and abroad. Rail repair can be divided into rail grinding, rail planing, rail milling, etc. according to the processing method. [0003] Among them, there are several types of rail g...
