Problems solved by technology

However, the vibration reduction effect of this vibration isolation system is insufficient, and it is difficult to apply to environments with large vibrations.
Moreover, the spring structure is prone to structural damage due to corrosion, difficulty in withstanding intermittent high load pressure, and corrosion, resulting in a low service life of the spring vibration isolation system

Embodiment Construction

[0020] The working process of the rail damper 100 according to the present invention will be briefly described below. Herein, the "upper end" refers to the end close to the "first cylinder", and the "lower end" refers to the end away from the "first cylinder".

[0021] figure 1 A rail damper 100 according to one embodiment of the invention is shown. Such as figure 1 As shown, the rail shock absorber 100 includes a body 10 with an inner chamber 12 installed on a vehicle running rail (not shown). Specifically, the body 10 includes a first cylinder 20 and a second cylinder 30 , and the first cylinder 20 and the second cylinder 30 are configured as a cylinder or a square cylinder with an opening 25 . Wherein, the diameter of the second cylinder 30 is set to be the diameter of the first cylinder 20 , so that the end of the second cylinder 30 close to the opening 25 can be inserted into the first cylinder 10 to form the body 10 .

[0022] And when the second cylinder 30 is inser...

Abstract

The invention provides a rail shock absorber which comprises a body, the body comprises a first barrel and a second barrel capable of being inserted into the first barrel, and the first barrel can move relative to the second barrel under the action of external force, so that the size of the body is changed. An elastic piece is arranged in the second barrel body, the elastic piece is provided with a free end extending out of the first barrel body, and the free end can abut against the first barrel body so as to hinder relative movement between the first barrel body and the second barrel body. According to the rail shock absorber, the shock absorption effect on a rail can be improved, and meanwhile the service life is prolonged.

Description

technical field [0001] The invention relates to a rail shock absorber. Background technique [0002] With the rapid development of urban rail transit, the environmental vibration problem caused by urban rail transit has become increasingly prominent. At present, the most common method in track vibration control is to insert an elastic support layer between the upper track structure and the lower foundation to form a steel spring floating plate. This kind of vibration-damping track dampens the train through the inertial motion of the upper track structure on the elastic support layer. Vibration generated by operation. [0003] The steel spring floating slab damping track is to place the concrete track bed slab with certain mass and rigidity on the steel spring vibration isolator to form a mass spring vibration isolation system. However, the vibration reduction effect of this vibration isolation system is insufficient, and it is difficult to be suitable for environments with...
