Full-automatic accurate adjustment device for track plate of ballastless track of high speed railway

Abstract

The invention discloses a full-automatic accurate adjustment device for a track plate of a ballastless track of a rapid transit railway, comprising a plurality of adjusters, a console, a power distribution box and a frame, wherein the adjusters are used for adjusting accurate adjustment claws arranged on the track plate required to be accurately adjusted and located; the console is used for synchronously controlling and driving the adjustment direction and adjustment amount of the adjusters according to deviates; the power distribution box is connected with the console; the frame moves forward and backward; the adjuster and the console are arranged suspended on the moveable frame; and each adjuster comprises an altitude adjuster and a direction adjuster, wherein the altitude adjuster and the direction adjuster are respectively connected with the horizontal screw and vertical screw of the accurate adjustment claw through a connection joint sleeve and a double pressing screw. The devicecan be used for automatically adjusting and accurately locating the track plate instead of manual work under the guide of measurement frame data, thereby effectively improving the adjustment efficiency and location precision of the track plate. The device is simple in structure and is convenient to use and operate.

Description

technical field [0001] The invention belongs to the technical field of adjustment and positioning of ballastless track track slabs, and in particular relates to a full-automatic fine adjustment device for ballastless track track slabs of high-speed railways. Background technique [0002] The ballastless track of high-speed railway is different from the traditional railway construction method. Its rail is installed on the basis of prefabricated or cast-in-place track slab by fasteners. This kind of track with slab structure prefabricated by special cement is called slab type. track, and this slab is called a track slab. At present, several high-speed railways under construction in my country have adopted this method. In the construction of the slab track, the most important link is the precise positioning and adjustment of the track slab. When the actual positioning adjustment is performed, the spatial position of the track slab must match the theoretical position of the des...

AI Technical Summary

Problems solved by technology

[0006] 1) The deviation information of the track slab is transmitted by the surveyor to the adjustment worker by shouting. The distance between the two is 13 meters or 19.5 meters. After one measurement, the surveyor must transmit 4 sets of movement data and directions to the adjustment worker, which is very hard and error prone

[0007] 2) According to the surveyor's instructions, the adjustment worker uses a manual wrench to turn the screw rod of the fine adjustment claw to move the track plate, which is labor-intensive

[0008] 3) The four adjustment workers cannot move synchronously, so the adjustment process affects each other

[0009] 4) It is impossible to grasp the rotation angle by manually rotating the screw rod, and it is difficult to achieve the action accuracy of 0.5mm in one rotation adjustment. Therefore, it is necessary to repeat the measurement and adjustment many times before the adjustment accuracy requirement of 0.3mm can be achieved.

[0010] In summary, due to the influence of the above factors, the efficiency of the manual fine-tuning method always has an inevitable limit value, and the fine-tuning accuracy is not high, so the fine-tuning positioning of the track slab becomes the key control point and construction progress of the slab track construction the constraints
