Problems solved by technology
Existing corrugation grinding machines all use grinding wheels as grinding tools, which have the following disadvantages: the grinding wheel and the rail are in rigid contact, and the vibration of the grinding operation can easily cause damage to the rail; the contact area between the grinding wheel and the rail is small, and the grinding efficiency is low; the power source uses an internal combustion engine, resulting in Environmental pollution; in order to eliminate wave grinding, a large number of rollers are arranged at both ends of the grinding machine, resulting in an excessively long longitudinal dimension along the rail

The invention provides a rechargeable abrasive belt grinder for rail corrugations. The rechargeable abrasive belt grinder mainly comprises a rack, an abrasive belt grinding unit, a power drive device, guide wheels, a digital display device, a deflection mechanism, a transition mechanism and a pressing mechanism, wherein the abrasive belt grinding unit comprises an abrasive belt, a drive wheel, rowed contact wheels, a tensioning wheel and an installation base plate; the abrasive belt is sequentially wound on the excircles of the drive wheel, the tensioning wheel and the rowed contact wheels; the rowed contact wheels are three profiling contact wheels which are sequentially placed in parallel along the direction of a rail; the power drive device comprises a storage battery, an inverter, a three-phase asynchronous motor, V-belt wheels and a V-shaped belt; and the V-shaped belt is wound on the two V-belt wheels. The rechargeable abrasive belt grinder provided by the invention is capable of increasing the grinding efficiency through using the abrasive belt as a grinding tool, and capable of avoiding the influence of rigid contact between an abrasive wheel and the rail, and vibration on the grinding quality; and meanwhile, the grinder is compact in structure, and simple and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of railway maintenance machinery, in particular to a rechargeable rail wave grinding belt grinder. Background technique [0002] The harsh service environment of railway rails is prone to various damages, among which corrugation is the most common and difficult to eliminate. Existing corrugation grinding machines all use grinding wheels as grinding tools, which have the following disadvantages: the grinding wheel and the rail are in rigid contact, and the vibration of the grinding operation can easily cause damage to the rail; the contact area between the grinding wheel and the rail is small, and the grinding efficiency is low; the power source uses an internal combustion engine, resulting in Environmental pollution; in order to eliminate wave grinding, a large number of rollers are arranged at both ends of the grinding machine, resulting in an excessively long longitudinal dimension along the rail.
