Embodiment Construction
[0033] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0034] Such as Figure 1-5 As shown, a frame level adjustment mechanism for milling and grinding of sleepers includes a frame body 1, wherein it also includes a plurality of sets of jacking jaws set along the front and rear directions of the frame body 1, each of which The jacking jaw group includes two jacking jaws 2 symmetrically arranged on the left and right sides of the frame body 1. The jacking jaws 2 include a die head 21 and a jacking drive device 22. The jacking drive device 22 Located on the frame main body 1, the power output end of the jacking drive device 22 is connected to the die head 21 and drives the die head 21 to perform vertical lifting movement, and a fixing groove 211 is provided under the die head 21, The fixing groove 211 is matched with the sleeper 91 .
[0035] After adopting the abo...

The invention discloses a frame level adjustment mechanism for milling and grinding of sleepers, which includes a frame body, wherein it also includes a plurality of sets of jacking jaws arranged along the front and rear directions of the frame body, each of the jacking The jaw group includes two jacking jaws symmetrically arranged on the left and right sides of the frame body. The jacking jaws include a die head and a jacking drive device. The power output end of the jacking drive device is connected to the die head and drives the die head to move vertically. A fixing groove is provided under the die head, and the fixing groove is matched with the sleeper. After adopting the above-mentioned structure, compared with the prior art, the present invention can adjust the height of the frame main body, so that the frame main body can be adjusted to a horizontal position on the arched railway foundation, which is convenient for the cutter head on the frame main body to adjust the sleeper. Milling and grinding in the horizontal direction improves the precision of milling and grinding.
Description
technical field [0001] The invention relates to the technical field of sleeper milling and grinding, in particular to a frame level adjustment mechanism for sleeper milling and grinding. 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 track 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. Such as figure 2 As shown, the plane S is set as the horizontal base plane, the railway foundation 1' is arched, the upper surface of the railway foundation 1' is inclined relative t...
