Abstract

The invention discloses a fastener device for urban rail transit, which comprises a steel rail, a shock-absorbing pad attached under the rail, a base attached under the shock-absorbing pad, and a first screw thread is arranged in the base The base is provided with a second threaded sleeve, the base is provided with a first clamping block, the first clamping block is provided with a third threaded sleeve, and the third threaded sleeve is internally threaded. There is a first screw, the first screw runs through the third threaded sleeve and is rotatably connected to the second threaded sleeve, a first shock absorbing spring is provided between the first block and the base, and the connection between the first block and the rail A second damping spring is arranged between them, and a second clamping block is pasted on the first clamping block. The invention has stable structure and good anti-seismic performance, and the structure of double buckles and double shock-absorbing springs has better track elasticity, can reduce vibration and noise, can save a lot of time and energy of workers, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of rail fasteners, in particular to a fastener device for urban rail transit. Background technique [0002] Fasteners are devices used to fix rails in rail transit, and are an important part of the track structure. The correct position of the rail prevents the vertical and horizontal displacement of the rail. The existing rail fastener structure is not stable enough, has poor seismic performance, does not have good track elasticity, and cannot achieve the effect of vibration reduction and noise reduction. Contents of the invention [0003] The object of the present invention is to solve the shortcoming of insufficient damping capacity in the prior art, and propose a fastener device for urban rail transit. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A fastener device for urban rail transit, comprising a steel rail, under which a ...
