Internal combustion type rail belt grinder

Abstract

The invention discloses an internal combustion type rail belt grinder, comprises a rack, a sanding belt, a driving wheel, a contact wheel, a tension pulley, a front travel contour wheel, a rear travel contour wheel and an explosive motor, wherein the front travel contour wheel and the rear travel contour wheel are arranged on the rack; the explosive motor is arranged on the rack and drives the driving wheel to rotate; the sanding belt is orderly wound on the excircles of the driving wheel, the contact wheel and the tension wheel; and a regulation mechanism for regulating the height of the rack is arranged between the rack and the front travel contour wheel or between the rack and the rear travel contour wheel. In the invention, the sanding belt is adopted to grind; the excircle of the contact wheel pressing the sanding belt on a welding line is provided with annular rubbers; the sanding belt is contacted with the welding line in a flexible mode, and the contact area is large, and the grinding efficiency is high; the variation in sanding belt thickness is small during grinding, thus the regulating operation of the grinding height is less, and the work efficiency is high; the regulation mechanism of the invention is simple, and the regulation is convenient and reliable; the driving wheel, the contact wheel and the tension wheel are all arranged on the support plate and the mounting and the debugging are convenient; and the explosive motor is suitable for field electroless operation.

Description

technical field [0001] The invention relates to a grinder, in particular to an internal combustion type steel rail abrasive belt grinder. Background technique [0002] After on-line welding and welding repair of railway rails, the weld seams need to be polished to make the surface of the rails smooth. In the traditional welding seam grinding operation, grinding wheel grinding machines are often used for grinding rail welds. The grinding wheel grinding machine has large dimensions, heavy equipment, complex structure, high operating intensity, and inconvenient maintenance. At the same time, the grinding wheel grinding machine uses grinding wheel grinding. The grinding wheel and rail Rigid contact, large vibration, and the speed of the grinding wheel should not be too high, so the grinding efficiency of the grinding wheel is low, and it is difficult to meet the requirements of short-term skylight operations; at the same time, because the contact area between the grinding wheel ...

In the traditional welding seam grinding operation, grinding wheel grinding machines are often used for grinding rail welds. The grinding wheel grinding machine has large dimensions, heavy equipment, complex structure, high operating intensity, and inconvenient maintenance. At the same time, the grinding wheel grinding machine uses grinding wheel grinding. The grinding wheel and rail Rigid contact, large vibration, and the speed of the grinding wheel should not be too high, so the grinding efficiency of the grinding wheel is low, and it is difficult to meet the requirements of short-term skylight operations; at the same time, because the contact area between the grinding wheel and the weld is small, the grinding wheel wears quickly, and the height of the grinding wheel must be adjusted continuously during the grinding process. The operator is labor intensive
