Fine adjustment vehicle for CRTS I type ballastless track slab pavement

Abstract

The invention discloses a fine adjustment vehicle for China railway track system (CRTS) I type ballastless track slab pavement, which is characterized by comprising a hood frame and a traveling part, wherein the hood frame is provided with a fine adjustment mechanism storage tank, an industrial personal computer and an electrical control cabinet; when the fine adjustment vehicle travels in place,a fine adjustment servo mechanism is taken out of the fine adjustment mechanism storage tank and is manually connected with a fine adjustment claw put on a foundation by an operator; the fine adjustment servo mechanism is connected with two fine adjustment claws with three or two degrees of freedom on one side of a ballastless track slab, and is connected with a fine adjustment claw with one degree of freedom, and a gravitational balance compensation type fine adjustment claw with three or two degrees of freedom on the other side of the ballastless track slab; and the industrial personal computer receives measuring data of a track slab prism reference instrument and sends an adjustment control signal to the fine adjustment servo mechanism. The fine adjustment vehicle for the CRTS I type ballastless track slab pavement has low labor intensity, a high adjustment speed, high adjustment precision, a rational design and complete functions, needs a few operators and can freely adjust the CRTS I type ballastless track slab in horizontal and vertical directions without additional interference constraint.

Description

technical field [0001] The invention belongs to a fine adjustment device used in the construction of a ballastless track project of a high-speed railway, in particular to a fully automatic CRTS I type 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. [0003] The CRTS I-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 as a one-way threaded screw adjustment, and there is a gap in the reverse adjustment, especially It is due to the error caused by wear and tear, up to several mil...

AI Technical Summary

Problems solved by technology

[0003] The CRTS I 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 It is due to the error caused by wear, up to several millimeters, and it is difficult to realize automation. The above-mentioned current technology has at least the following disadvantages: high labor intensity, slow adjustment speed, low adjustment accuracy, many operators, and difficult to realize automatic operation
