A comb-tooth plate multi-directional displacement bridge telescopic device and torsion method

Abstract

The invention belongs to the technical field of transportation means, and particularly relates to a telescopic device of a comb plate type multi-direction deflecting bridge, and a twisting method. The telescopic device comprises a crack crossing movable comb plate and a fixed comb plate, wherein stainless steel plates are arranged under positions where comb teeth of the crack crossing movable comb plate and comb teeth of the fixed comb plate are crossed; a multi-direction deflecting device is laterally arranged at the lower part of the tail end of the crack crossing movable comb plate, and comprises a plurality of deflecting boxes, and the deflecting boxes comprise deflecting boxes II; each of the deflecting boxes II comprises a box body with an opening in the upper part; each of the box bodies comprises an upper connecting block and a lower connecting block which are in sliding fit in a manner that a concaved spherical surface and a convex spherical surface are embedded; the upper connecting blocks are fixedly connected with the crack crossing movable comb plate; and each of the lower connecting blocks is fixedly connected with a bottom plate of the corresponding deflecting box II. The telescopic device disclosed by the invention is characterized in that the deflecting boxes also comprise a deflecting box I; the deflecting box I comprises a box body I with an opening in the upper part; the box body I comprises a U-shaped bolt and a fixed bolt, wherein the U-shaped bolt is fixedly connected with the crack crossing movable comb plate; the fixed bolt is fixedly connected with the box body; and the U-shaped bolt can twist around the fixed bolt, and can adapt to the situation of vehicle flows.

Description

technical field [0001] The invention belongs to the technical field of transportation facilities, and in particular relates to a multi-directional displacement bridge expansion device and a twisting method of a comb tooth plate. Background technique [0002] In recent years, with the increase of infrastructure investment, the field of highways has developed by leaps and bounds, and the development of bridge expansion devices has attracted more and more attention. The telescopic device and its installation method" (Patent No. ZL201110125568.2) is optimized on the basis of the design, so that it has a more superior multi-directional displacement function, and the installation is more convenient and fast. [0003] The defect of the prior art is that sometimes the traffic flow is one-way, causing the contact part to be twisted, otherwise the road surface will not be level after a long time. Contents of the invention [0004] Purpose of the invention: In order to provide a mod...
