Example Embodiment

[0066] Such as figure 1 , figure 2 A slab-type ballastless track track plate replacement device shown includes a lateral sliding mechanism, a temporary support structure for horizontally supporting the lateral sliding mechanism, and driving the track plate to be moved horizontally on the lateral sliding mechanism For the lateral sliding traction equipment, the lateral sliding mechanism is arranged horizontally and is fixedly installed on the temporary supporting structure. The traction equipment includes a left traction mechanism 3-1 and a right traction mechanism 3-2 respectively arranged at the left and right ends of the lateral sliding mechanism, and the lateral sliding mechanism is arranged perpendicular to the damaged track plate 1 to be replaced. Left and right hanging ears 12 and 13 are respectively installed on the left and right side walls of the track plate to be moved horizontally. The left and right hanging ears 12 and 13 are arranged symmetrically, and the left tra...

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 ...
