Embodiment 2

[0060] refer to Figure 8 The difference between this embodiment and Embodiment 1 is that the base 1 is provided with the two side walls of the positioning groove 12 and is fixedly connected with the connecting frame 14, and the connecting frame is fixed with a drainage slope 30 towards the track seat 20. A vacuum chuck 141 is provided on the surface, and the mouth of the vacuum chuck 141 is arranged parallel to the attachment slope 11 . After the staff set up the fine adjustment device, the vacuum suction cup 141 is attached to the surface of the drainage slope 30 of the track seat 20, and the staff applies glass sealant between the circumferential side wall of the vacuum suction cup 141 and the drainage slope 30 of the track seat 20, And the glass sealant is compacted to form a rubber seal (not shown in the figure), thereby improving the sealing performance, and then vacuuming the vacuum chuck 141, so that the vacuum chuck 141 is adsorbed on the surface of the drainage slope...

Abstract

The invention relates to a fine adjustment device for an intelligent fine adjustment system of a ballastless track plate. The device comprises a base, a Y-direction adjustment structure is arranged onthe base, a Y-direction adjustment head and an X-direction adjustment structure are arranged on the Y-direction adjustment structure, an X-direction adjustment head and a Z-direction adjustment structure are arranged on the X-direction adjustment structure, and a Z-direction adjustment head is arranged on the Z-direction adjustment structure. Steering mechanisms are arranged between the X-direction adjustment structure and the X-direction adjustment head and between the Z-direction adjustment structure and the Z-direction adjustment head respectively, the steering mechanisms adjust the transmission direction to enable the X-direction adjustment head, the Y-direction adjustment head and the Z-direction adjustment head to face the same direction, and a connecting piece is arranged on the Z-direction adjustment structure. The adjustment device has the effects that all the adjustment structures are arranged to adjust the position of the connecting piece in the space coordinate system, a track plate is straightened and leveled through cooperation of the connecting pieces of the multiple fine adjustment devices, and meanwhile, the orientations of all the adjustment heads are consistentthrough the arrangement of the steering mechanisms, so workers can operate all the adjustment heads more conveniently.

Description

technical field [0001] The present application relates to the field of railway construction technology, in particular to a fine-tuning device for an intelligent fine-tuning system for ballastless track slabs. Background technique [0002] The track slab of high-speed railway is the foundation of rail laying. In order to meet the precision requirements of rail laying, the track slab needs to be precisely ground by machine tools in prefabrication production before being placed on the construction site. After the construction is completed, the positioning must be precisely adjusted to meet the requirements of the rail. laying requirements. Ballastless track is a track without gravel and is made of reinforced concrete. Compared with ballasted track, ballastless track can maintain the shape and position of the rail for a long time, and does not require large-scale maintenance during a long service period. It also has the characteristics of good durability, clean and beautiful tr...
