Device and method for replacing track slab of slab ballastless track

Abstract

The invention discloses a device and method for replacing a track slab of a slab ballastless track. The device comprises a lateral sliding mechanism, a temporary support structure and traction equipment, wherein the temporary support structure is used for performing horizontal support on the lateral sliding mechanism; the traction equipment is used for driving a track slab which needs to be laterally moved to laterally slide on the lateral sliding mechanism; the lateral sliding mechanism is horizontally arranged on the temporary support structure; and the lateral sliding mechanism is erected above a base plate on which a damaged track slab is located through the temporary support structure. The method comprises the following steps of: I, moving up steel rails; II, moving up the damaged track slab; III, erecting the lateral sliding mechanism; IV, laying the damaged track slab flatwise; V, moving right the damaged track slab; VI, hoisting the damaged track slab away and lifting a new track slab; VII, moving left the new track slab; VIII, removing the lateral sliding mechanism; IX, installing the new track slab; and X, moving down the steel rails and mounting. The device for replacing the track slab of the slab ballastless track is reasonable in design, easy and simple in use and operation and good in using effect, and the method for replacing the track slab of the slab ballastless track can be conveniently realized, and can be used for efficiently, rapidly and simply completing the replacement process of the track slab of the slab ballastless track.

Description

technical field [0001] The invention belongs to the technical field of track slab replacement of slab-type ballastless track, and in particular relates to a track slab replacement device and method for slab-type ballastless track. 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. The slab ballastless track is a new type of track structure composed of concrete base, CA mortar layer, track plate, fasteners and rails. The slab ballastless track cancels the sleeper and ballast bed of the traditional ballast track, and uses the prefabricated reinforced concrete slab to directly support the rail, and fills the CA mortar cushion between the track slab and the concrete ...

AI Technical Summary

Problems solved by technology

In the actual replacement of track slabs, the above-mentioned existing replacement methods require the use of many large-scale equipment such as track cutting and welding, and the construction process is complicated and labor-intensive, especially track welding and locking operations are required, so the environmental requirements for construction has its limitations
