CRTS III type plate-type ballastless-track track-board fine-tuning frame

Abstract

The invention belongs to the field of high-speed-railway ballastless-track equipment, and relates to a track-board fine-tuning frame, in particular to a CRTS III type plate-type ballastless-track track-board fine-tuning frame. The CRTS III type plate-type ballastless-track track-board fine-tuning frame comprises a prism column. A prism hole is formed in the center of the top end of the prism column (2) and used for placing a micro prism, a cross beam (3) is arranged below the prism column, and two cylindrical bases (4) are connected with the lower portion of the cross beam (3); the vertical axes of the two bases (4) and the prism column (2) are located on the same straight line, the axis of the prism column (2) is located at the center of the link of the axes of the two bases (4), and discs (5) are arranged below the two bases correspondingly; and a fixed positioning pin (7) is arranged below one disc, a bolt-hole movable taper positioning pin (6) is arranged below the other disc, and the circle center of the movable taper positioning pin (6) is always consistent with the circle center of the corresponding disc (5). According to the CRTS III type plate-type ballastless-track track-board fine-tuning frame, the horizontal position, the longitudinal position and the elevation position of a track board can be detected simultaneously, the shape is small and exquisite, and construction operation is convenient.

Description

technical field [0001] The invention belongs to the field of ballastless track equipment for high-speed railways, and relates to a track slab fine-adjustment frame, in particular to a CRTSⅢ slab-type ballastless track track slab fine-adjustment frame. Background technique [0002] At present, the well-known track slab fine adjustment frame is positioned by the large jaw positioning method, which can achieve the purpose of precise positioning of the track slab lateral position and elevation, but the frame can slide vertically on the rail support platform, and the limit point, resulting in The longitudinal position of the track slab cannot be detected, and the CRTSⅢ track slab fine-tuning construction technology requirement of my country's independent intellectual property rights cannot meet the standard that the longitudinal position deviation of the track slab does not exceed 5mm. Contents of the invention [0003] In order to overcome the problem that the existing fine-adj...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the problem that the existing fine-adjustment frame cannot locate the longitudinal position of the track slab, the present invention provides a fine-adjustment frame, which can not only detect the lateral position and elevation position of the track slab, but also detect the longitudinal position of the track slab Position, to achieve real three-dimensional positioning
