Anti-bending straight rail groove

Abstract

The invention discloses an anti-bending straight rail groove, and relates to the technical field of rail grooves. The anti-bending straight rail groove comprises a rail groove channel and two mounting plates, and the two mounting plates are respectively fixed at the lower edge positions of the left end and the right end of the rail groove channel; an inner cavity is formed in the lower portion of the interior of the rail groove channel, an upper pressure-resistant plate and a lower pressure-resistant plate are arranged on the upper side and the lower side of the interior of the inner cavity correspondingly, the lower surface of the upper pressure-resistant plate and the upper surface of the lower pressure-resistant plate are each provided with four semi-circular grooves which correspond up and down, and extrusion soft cushions are attached to the inner walls of the semi-circular grooves; a plurality of upper latches which are horizontally arranged at equal intervals are fixed on the front and rear side edges of the bottom of the upper pressure-resistant plate, and a plurality of lower latches which are horizontally arranged at equal intervals are fixed on the front and rear side edges of the top of the lower pressure-resistant plate; the straight rail groove has the beneficial effects that through the upper pressure-resistant plate, the lower pressure-resistant plate, the pressure-resistant air bag, the first pressure-dividing air bag, the second pressure-dividing air bag and the pressure-resistant shaft, the pressure-resistant performance of the straight rail groove can be effectively improved, and meanwhile the phenomenon that the straight rail groove is bent and deformed after being pressed is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a bending-resistant straight rail groove. Background technique [0002] The rail groove refers to a new type of under-rail component whose structure is a plate body, used to support and fix the rail, and distributes the load transmitted by the train through the rail to the base under the plate. When the existing straight rail groove is under pressure, not only It is prone to bending deformation, and its own compression resistance is poor, which makes the straight rail groove very prone to deformation, which affects the use. Contents of the invention [0003] The present invention provides a bending-resistant straight rail groove to solve the problem that the straight rail groove proposed in the above-mentioned background technology is prone to bending deformation when it is under pressure, and its own compression resistance is poor, resulting in the straight rail groove being ...
