Example Embodiment

[0020]Example 1

[0021]SeeFigure 1~3In an embodiment of the present invention, a subway track shock absorption device includes a track 1, and a bottom pad 2 is provided at the lower end of the track 1, and the bottom pad 2 can play a role in damping and buffering the track 1, and the bottom pad 2 is provided at the lower end There is a support plate 3, the lower end of the support plate 3 is fixedly connected with a support rod 4, the lower end of the support rod 4 is provided with a sleeve 5, the sleeve 5 is provided with a groove 6 and the support rod 4 is slidably installed in the groove 6 to support The rod 4 can slide up and down in the groove 6 to drive the support plate 3 to move up and down. The lower end of the sleeve 5 is integrally connected to the bottom tube 7, and the bottom tube 7 is provided with a groove 2 8, and the lower end of the support rod 3 is integrated A boss 9 is connected, and the boss 9 is slidably mounted in the groove two 8. The diameter of the boss 9 is...

Example Embodiment

[0026]Example 2

[0027]In order to further increase the damping effect of the rail 1, this embodiment is further improved on the basis of embodiment 1. The improvement is: the rail 1 is provided with a damping pad 19, which can dampen the subway When the subway is running on the track 1, the shock-absorbing pad 19 can play a very good shock-absorbing effect.

[0028]The working principle of this embodiment is: in order to further increase the damping effect of the track 1, a damping pad 19 is provided on the track 1. The damping pad 19 can absorb the shock of the subway. When the subway is running on the track 1, The shock-absorbing pad 19 can play a very good shock-absorbing effect.

[0029]In summary, by arranging spring 10, spring 10 can slow down the downward movement of support plate 4 and buffer the track 1. When encountering uneven road sections, spring 10 can also act as a shock absorber. To ensure the smooth operation of the subway; by setting the bottom cushion 2, the track 1 can ...

Abstract

The invention discloses a subway rail damping device which comprises a rail. A bottom pad is arranged at the lower end of the rail, supporting plates are arranged at the lower end of the bottom pad, supporting rods are fixedly connected to the lower ends of the supporting plates, sleeves are arranged at the lower ends of the supporting rods, first grooves are formed in the sleeves, the supportingrods are slidably installed in the first grooves, and the supporting rods can slide up and down in the first grooves to drive the supporting plates to move up and down. The lower ends of the sleeves are integrally connected with bottom cylinders, second grooves are formed in the bottom cylinders, the lower ends of the supporting rods are integrally connected with bosses, the bosses are installed in the second grooves in a sliding mode, the diameter of the bosses is larger than that of the first grooves, first springs are arranged on the outer sides of the sleeves, one ends of the first springsare fixedly connected to the lower ends of the supporting plates, and the other ends of the first springs are fixedly connected to the bottom cylinders. Through the arrangement of the first springs,the downward moving speed of the supporting plates can be decreased through the first springs, the buffering effect on the rail is achieved, when a subway vehicle encounters an uneven road section, the first springs can further achieve the damping effect, and stable running of the subway vehicle is guaranteed.

Description

technical field [0001] The invention relates to the field of subway track devices, in particular to a subway track damping device. Background technique [0002] Subway refers to a rapid and large-capacity urban rail transit mode that is gradually developed along the surface railway system. Its lines are usually laid in underground tunnels, and some are outside the city center, from underground to ground or The way of laying on the viaduct. Regardless of the architectural form of the subway, it is a very important form of urban public transportation at the present stage. [0003] The subway covers all kinds of underground and above-ground right-of-way proprietary, high-density, high-capacity urban rail transit systems in urban areas. Due to the high value of urban land in general metropolises, building railways underground can save ground space and make the ground The land can be used for other purposes. Since the subway’s route does not overlap or intersect with other tran...
