Two-dimensional adjustable ballastless track slab die of track bearing slot

Abstract

The invention discloses a two-dimensional adjustable ballastless track slab die of a track bearing slot, comprising a bottom template and a two-dimensional adjustable mechanism of the track bearing slot below the bottom template, wherein the two-dimensional adjustable mechanism of the track bearing slot comprises a long press plate coplanar with the bottom template, a short press plate forming a rectangular frame with the long press plate, a bearing platform die regulation frame below the rectangular frame formed by the long press plate and the short press plate and an adjustable platform bearing die in the bearing platform die regulation frame; the shape of the inner cavity of the adjustable platform bearing die is matched with the shape of a track bearing slot of the track slab; the bottom of the adjustable platform bearing die is connected with a height adjustment mechanism; and the platform bearing die regulation frame is connected with a transverse adjustment mechanism. The die can realize the two-dimensional stepless regulation and control of the track bearing slot, and the production of ballastless track slabs with different outer track heights and transversely displaced track bearing platforms can be realized without changing the die in a production process. The invention improves the generality of the die, has convenient construction, reduces the manufacture and change cost of the die, improves the working efficiency and guarantees various design sizes of the track slabs.

Description

technical field [0001] The invention relates to a two-dimensionally adjustable ballastless track slab mold for railway track bearing grooves, in particular to a two-dimensionally adjustable ballastless track slab mold for producing CRTS III slab concrete ballastless tracks. 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 production process of ballastless track slabs, the bottom mold of the track slab mold cannot be used universally, and the rail bearing groove and the bottom mold on the track slab mold are an integral structure, which is feasib...

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 CRTSⅢ type slab concrete ballastless track with two-dimensional stepless regulation of the bearing groove
