Track damping shock absorber

Abstract

The invention discloses a rail damping shock absorber, which comprises a damping structure laid on the rail waist of the rail, and also includes a clamping assembly clamping the damping structure close to the rail waist, and the clamping assembly includes a left clamping part and the right clamping part, and a connecting part detachably connecting the left clamping part and the right clamping part. Compared with the rail body of the track, the damping structure has a higher damping loss factor, which can fully play the role of energy conversion and ensure the noise reduction performance of the damping shock absorber. At the same time, since the clamping component can clamp the damping structure closely to the rail waist, the damping structure and the rail waist do not need to be fixedly connected together; when the track or the damping structure needs to be replaced, the connection between the left clamping part and the right clamping part The locking relationship between the track and the damping structure can be replaced separately, and the usable structure can still be used to reduce the waste of track maintenance, avoid unnecessary economic losses, and improve the cost performance of the damping shock absorber.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a rail damping vibration absorber. Background technique [0002] Noise is a source of environmental pollution, which is extremely harmful to people's physical and mental health. All countries are increasing their efforts to control noise. At present, the train speed continues to increase, and the wheel-rail noise caused by the increase of train speed is on the rise. The noise of trains running at a speed below 250Km / h mainly comes from wheel-rail noise, and rail vibration is the main cause of wheel-rail noise. [0003] In order to reduce the pollution of wheel and rail noise, acoustic workers and scientific and technical personnel at home and abroad have proposed treatment measures such as the use of heavy-duty steel rails, super-long seamless lines, regular grinding of steel rails, the use of muffler wheels, the construction of sound barriers, and the use of damped ...

Problems solved by technology

[0005] like figure 1 As shown, the damping shock absorber 11 in the prior art is fixedly connected with the rail body 12 of the rail. When the rail needs to be replaced, the damping shock absorber 11 will be replaced together. At this time, the damping shock absorber 11 can still be used. But it will be replaced together with the rail body 12, and there is a lot of waste; but it is difficult to ensure that the rail body 12 and the damping shock absorber 11 are scrapped at the same time during use, so waste is inevitable
