A sleeper cutting head

Abstract

The invention discloses a sleeper cutting cutter head, which includes a rotating shaft, and further includes a first cutting body for cutting the inclined surface of the sleeper, and a second cutting body for cutting the arc surface of the sleeper; the first cutting body Sleeved in the middle of the rotating shaft, the first cutting body includes several cutting knife groups; the second cutting body includes both ends of the rotating shaft. After adopting the above-mentioned structure, when cutting, the present invention is approached and embedded in the profile surface of the sleeper, the first cutting body is attached to the inclined surface of the profile surface, and the second cutting body is embedded in the arc-shaped surfaces on the left and right sides of the inclined surface Fitting; then the first cutting body and the second cutting body are driven by the power device to drive the rotating shaft to cut the profile surface of the sleeper. Compared with the prior art, the beneficial effect is that the present invention can closely fit the profile surface of the sleeper, improve the cutting precision and cutting quality, and only need one positioning during processing, making the cutting process more convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of sleeper processing tools, in particular to a sleeper cutting tool head. Background technique [0002] The sleeper is a kind of railway accessories. Its main function is to support the rails, maintain the position of the rails, and transfer the huge pressure from the rails to the track bed. Most of the existing railway tracks, especially high-speed railway tracks, are ballastless tracks with good ride comfort and high stability. The sleepers on the ballastless track are made of reinforced concrete material, which has higher stability and longer service life. [0003] In actual situations, the geology will arch upwards due to stress changes, resulting in arching diseases of railway tracks. Since the railway track is sensitive to the track reference height, the level difference per kilometer needs to be controlled within 2mm. Therefore, small changes in the geological structure can easily exceed this limi...

Problems solved by technology

However, the width of the existing cutting head is relatively narrow, and the cutting area is small. It is necessary to position the cutting head on the profile surface many times, and the operation is very cumbersome. In addition, the profile surface of the sleeper is divided into inclined surface and arc Shaped surface, after the existing cutting head is positioned and cut for many times, the inclination angle of the inclined surface is prone to errors, and the position of the arc surface is small, and the existing cutting head cannot perform precise cutting on it, thereby reducing the cutting cost. Accuracy affects the normal fit and installation of rails
