Embodiment Construction

[0070] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0071] In the figure, the coordinate axes X, Y, and Z respectively represent the front-to-back direction, the left-right direction and the up-down direction of the present invention, and the coordinate axis X points to the front direction, the coordinate axis Y points to the right direction, the coordinate axis Z points to the upward direction, and the coordinate axes X, Y The intersection point of , Z is point O.

[0072] Such as Figure 1-13 As shown, a milling device for eliminating arching defects on railway sleepers, which includes a processing cutter head 21 for milling and grinding the sleeper, a cutter head rotating drive device 22 for driving the processing cutter head to run, and a device for driving the processing cutter head to move The cutter head moves the driving mechanism. Also comprise mobile...

Abstract

The invention discloses a milling and grinding device for eliminating upwarp diseases of railway sleepers, which comprises a machining tool bit for milling and grinding the sleepers, a tool bit rotation driving device for driving the machining tool bit to operate, and a tool bit movement driving mechanism for driving the machining tool bit to move. By the adoption of the structure, the machining tool bits are moved to the two sleepers in the same row through the tool bit movement driving mechanism and conduct tool setting, and the tool bit rotation driving device drives the machining tool bitsto rotate to conduct milling and grinding machining on the profile surfaces of the sleepers. Compared with the prior art, existing manual machining is replaced with mechanical automatic machining, machining is more convenient, and the labor cost is reduced; in addition, a plurality of sleepers can be machined at the same time, and the milling and grinding efficiency and the sleeper milling and grinding machining precision are improved.

Description

technical field [0001] The invention relates to the technical field of railway sleeper milling and grinding devices, in particular to a milling and grinding device for eliminating arching defects of railway sleepers. 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. Theref...
