Buckling limiting device based on rail base plate

Abstract

The invention discloses a buckling limiting device based on a rail base plate. The device comprises a base plate, two buried rods are welded at the bottom end of the base plate, and a supporting plateis welded to one end of the base plate. Two triangular blocks are welded between the supporting plate and the base plate, a groove is formed in the center of the top end of the supporting plate, anda rotating shaft is connected to the two ends of the supporting plate at the inner side of the groove in a penetrating manner. A connecting plate is welded at one end of the rotating shaft, by rotating a hexagonal cap, a screw rotates inwards as much as possible, so that the limiting plate at one end of the connecting plate and the supporting plate can rotate greatly. Then, the base plate is mounted beside the rail base plate through the buried rods, and then the hexagonal cap is rotated inwards, so that the screw rotates outwards, the limiting blocks at the bottom ends of the limiting platesmake contact with the rail base plate conveniently, and the limiting function is achieved. The vibration caused by the train running can be balanced conveniently through the first spring and the second spring, and therefore the phenomenon that the screw loosens due to the long-time vibration is prevented conveniently.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to a buckle and limit device based on a rail backing plate. Background technique [0002] Railway transportation is a kind of land transportation mode. The locomotives are used to pull trains and vehicles on two parallel rails. The traditional method is steel wheels, but the generalized railway transportation includes maglev trains, cable cars, cableways and other non-steel wheels. Way, or rail transportation, rails can provide an extremely smooth and hard medium on which the train wheels roll with minimal friction, making people feel more comfortable on it, and it can also save energy. If configured properly, rail transportation It can save 50% to 70% of energy compared with road transportation when carrying the same weight. Moreover, the rails can evenly distribute the weight of the train, which greatly increases the load capacity of the train; [0003] In the Chinese patent app...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a buckle and limit device based on the rail backing plate, which can effectively solve the above-mentioned background technology. However, for long-term use, due to the long-term train running on the railway, it causes vibration and cannot be disassembled. Secondly, for later disassembly What is complicated, due to the influence of the environment, the corrosion of the screw is caused, and the problem of horizontal twisting is inconvenient
