CRTS III ballastless track slab layering fine tuning vehicle

Abstract

The invention discloses a CRTS III ballastless track slab layering fine tuning vehicle. In the invention, a fine tuning mechanism storage box, an industrial personal computer (IPC) and an electrical cabinet are arranged on a hood frame; a travelling part comprises travelling wheels at the four lower corners of the hood frame, and at least two travelling wheels are connected with driving mechanisms; when the fine tuning vehicle travels to a proper place, a fine tuning servo mechanism taken out from the fine tuning mechanism storage box is manually connected with a fine tuning claw arranged on a foundation; the fine tuning servo mechanism is provided with two fine tuning claws with two degrees of freedom connected at one side of a ballastless track slab, and is also provided with a fine tuning claw with single degree of freedom and a gravitational equilibrium compensated fine tuning claw with three degree of freedom or two degree of freedom which are connected at the other side of the ballastless track slab; and the IPC receives the measurement data of a track slab prism station meter and sends an adjustment control signal to the fine tuning servo mechanism. The fine tuning vehicle has the advantages that the labor intensity is low, the adjusting speed is quick, the adjustment accuracy is high, operating workers are few, the design is reasonable, the functions are complete, and the ballastless track slab can be freely adjusted in the horizontal and vertical directions without additional interference and constraint.

Description

technical field [0001] The invention belongs to a fine adjustment device used in the construction of ballastless track engineering of high-speed railway, in particular to a fully automatic CRTSIII ballastless track slab laying fine adjustment vehicle. Background technique [0002] At present, with the rapid development of high-speed railways, slab ballastless track is widely used. The slab ballastless track has the advantages of comprehensive construction investment economy, mechanized manufacturing by factories, high production efficiency, and easy control, adjustment and repair. For example, the CRTSIII slab ballastless track developed based on the German Borg slab ballastless track system includes concrete bases under the slab, CA mortar cushions, track slabs, long rails and fasteners. [0003] The CRTSIII type ballastless track slab manual adjustment equipment in the prior art is all manually adjusted, and the up and down adjustment needs to be screwed with a long-arm wr...

AI Technical Summary

Problems solved by technology

[0003] The CRTSIII type ballastless track slab manual adjustment equipment in the prior art is all manually adjusted, and the up and down adjustment needs to be screwed with a long-arm wrench, and the horizontal direction is adjusted by a one-way threaded screw adjustment, and there is a gap in the reverse adjustment, especially The error caused by wear is as high as several millimeters, and it is difficult to realize automation. The above-mentioned existing technology has at least the following disadvantages: high labor intensity, slow adjustment speed, low adjustment accuracy, many operators, and difficult to realize automatic operation
