Urban rail transit rail quick connecting device

Abstract

The invention belongs to the technical field of rail transit equipment, and particularly relates to an urban rail transit rail quick connecting device which comprises a first guide rail and a second guide rail, one end of the first guide rail is slidably inserted into the surface of one end of the second guide rail, and the two ends of the first guide rail and the two ends of the second guide railare provided with a first clamping groove and an adjusting cavity correspondingly. And a second clamping groove is formed in the inner top wall of the first clamping groove, the inner wall of the second clamping groove is perpendicular to the inner wall of the first clamping groove, and a rapid mounting device is arranged in the adjusting cavity. According to the quick connecting device, the rapid mounting device is arranged in an adjusting cavity and comprises an adjusting rod, so that during mounting operation, rapid mounting, locking and fixing can be achieved, operation is easy, mountingand dismounting are easy and convenient, and two guide rails can be rapidly controlled to be firmly connected; and dangers caused by derailing after long-term use are avoided.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail quick connecting device for urban rail transit. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to run on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, more and more types of rail transit have emerged, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. [0003] The railway track usually consists of two parallel rails, which are fixed on the sleepers, and the ballast is placed under the sleepers. It is fastened by rail braces, fasteners, rail clamps, splints, spring bars, rail spikes and other railway accessories. [0004] When the existing two rails are connected and spliced, they all...

AI Technical Summary

Problems solved by technology

[0004] When the existing two rails are connected and spliced, they all adopt the clamping method, and they are locked and fixed by screws. When this method is fixed and then used for a long time, regular inspection is required to avoid long-term use of screws. Derailment affects traffic and personal safety, thereby increasing maintenance costs, and the screw connection is prone to rust for a long time in the sun and rain, making it difficult to disassemble later, so a quick connection device for urban rail transit rails is needed
