Sleeper cutting tool bit

Abstract

The invention discloses a sleeper cutting tool bit which comprises a rotating shaft, as well as a first cutting body used for cutting an inclined plane of a sleeper, and a second cutting body used forcutting an arc-shaped surface of the sleeper; the first cutting body is arranged in the middle of the rotating shaft in a sleeving mode, and comprises a plurality of cutter sets; and the second cutting body comprises two ends arranged on the rotating shaft in a sleeving mode. After the structure is adopted, during cutting, the sleeper cutting tool bit is close to and is embedded into the profilesurface of the sleeper, the first cutting body is attached to the inclined plane of the profile surface, and the second cutting body is embedded and attached to the arc-shaped surfaces of the right and left sides of the inclined plane; and then, the rotating shaft is driven by a power unit to drive the first cutting body and the second cutting body to cut the profile surface of the sleeper. Compared with the prior art, the sleeper cutting tool bit has the beneficial effects that the sleeper cutting tool bit can be tightly attached to the profile surface of a sleeper, and the cutting precisionand the cutting quality are improved; and only one-time positioning is needed during machining, and the cutting process is 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
