Two-dimensional adjustable ballastless slab die of support rail bed

Abstract

The invention discloses a two-dimensional adjustable ballastless slab die of a support rail bed, comprising a bottom template and a two-dimensional adjustable mechanism of a groove die. The two-dimensional adjustable mechanism of the groove die is arranged below the bottom template and comprises a rectangular groove die adjusting frame coplanar with the bottom template, transversal cushion blocksand longitudinal cushion blocks, wherein the transversal cushion blocks and the longitudinal cushion blocks are arranged inside the groove die adjusting frame and form a rectangular frame which is internally provided with the adjustable groove die, the shape of an inner cavity of the adjustable groove die is matched with the shape of the support rail bed of a slab, and a height-adjusting cushion block is arranged at the bottom of the adjustable groove die. The die can realize the two-dimensional adjustment of the support rail bed, can realize the production of the ballastless slabs which havedifferent rail outer side heights and are provided with the support rail bed capable of transversally moving without replacing the die in a production process, improves the generality of the die, is convenient to construct, decreases the manufacture and replacement cost of the die and the labor forces, improves the operation efficiency, and ensures various design sizes of slabs with attractive appearances.

Description

technical field [0001] The invention relates to a two-dimensionally adjustable ballastless track slab mold of a railway track bearing platform, in particular to a two-dimensionally adjustable ballastless track slab mold for producing a CRTS I type slab concrete ballastless track. Background technique [0002] Concrete track slab is one of the main components in the ballastless track structure, and it is produced by pouring concrete into the ballastless track steel mold. At present, the types of track slabs in China have tended to be diversified, such as: CRTS Ⅰ type ballastless slab track, CRTS Ⅱ type slab ballastless track, CRTS Ⅲ slab ballastless track, CRTS Ⅰ double block ballastless track, CRTS Ⅱ double block ballastless track. [0003] In the existing ballastless track slab production process, the bottom mold of the track slab mold cannot be used universally, and the rail bearing platform and the bottom mold on the track slab mold have an integrated structure, which is...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the above-mentioned ballastless track slab model and the bottom mold in the production process cannot be used universally, and the relative position of the embedded casing needs to be adjusted according to the turning radius of the ballastless track slab of various specifications and the height difference outside the track. To solve the problem of production, provide a ballastless track slab mold for the production of CRTS Ⅰ type slab concrete ballastless track with two-dimensional adjustment of the bearing platform of the ballastless track
