Description

TECHNICAL FIELD

[0001] The present application belongs to the field of rail transit, and particularly relates to a high-speed train stable track with a damping function. BACKGROUND

[0002] With the development of social economy and the progress of science and technology, various different forms of traffic lines (such as subways, light rails, viaducts, etc.) have emerged like mushrooms after a spring rain. Although the emergence of rail transit has greatly eased the traffic pressure, the environmental problems accompanying the emergence have gradually increased. Social conflicts caused by various environmental problems caused by elevated traffic are increasing, and people are paying more and more attention to the environmental problems caused by rail transit. Rail transit refers to a type of traffic tool or transportation system that requires vehicles to run on a specific track. Rail transit plays an increasingly important role in urban transportation. The vibration generated by the train running on the track will affect the service life of the track. A damping pad is usually laid at the bottom of the track to dampen the track.

[0003] The railway subgrade is a structure that bears and transmits the track gravity and the dynamic action of the train, and is the foundation of the track and an important building that ensures the operation of the train. The subgrade is a soil and stone structure, which is in various topography, geology, hydrology and climate environments, and sometimes suffers from various disasters such as floods, mudslides, landslides, earthquakes, etc. With the rapid development of economy and society, the passenger and freight traffic volume of railways has also increased significantly. The carrying capacity of most existing railways has not met the needs of transportation growth, and expansion and reconstruction must be carried out. However, in the expansion and reconstruction project of the existing line, the intensification of vibration is inevitable. After the expansion and reconstruction of the line, the vibration will inevitably be greater due to the increase in load and speed.

[0004] Therefore, it is an important condition to improve the stability of train running and the service life of the track to reduce the vibration between the train and the track when the train runs on the track. Therefore, it is a technical problem to be solved in the prior art to reduce the vibration when the train runs on the track. SUMMARY

[0005] The present application aims to provide a high-speed train stable track with a damping function. The track unit is supported by the first damping unit assembly arranged on the sleeper uniformly distributed on the concrete base, and the second damping unit assembly is used to connect and dampen the adjacent two sleepers, so that the track unit has the damping function and effect in the vertical direction, the lateral direction and the front and rear direction, and the position adjustment of the adjacent two track units can be adjusted during the train running.

[0006] The application aims at achieving the following technical effects.

[0007] The application has the following beneficial effects:

[0008] 1、In the application, a plurality of sleepers are arranged along the length direction of the concrete base, and two symmetrical first damping unit assemblies are arranged at the upper end of the sleepers to support and damp the track unit, thereby ensuring the stability of the track unit supported by the first damping unit assemblies during train running; further, a second damping unit assembly is arranged between the two adjacent sleepers to provide damping support, so that when the distance between the two sleepers changes, the supporting plate arranged at the upper end of the second damping unit assembly is kept at the same level, and the two adjacent track units are stably supported and damped, so that the two adjacent track units have a slight deformation space and stable damping support, thereby enhancing the stability of the plurality of track units during train running.

[0009] 2、In the application, a movable mounting groove is arranged in the sleeper, and a damping support assembly in the first damping unit assembly is arranged in the movable mounting groove to provide stable damping support, and the damping support assembly has a lateral auxiliary damping unit and a vertical damping unit, so that the first damping unit assembly as a whole has damping support effect in the lateral direction and the vertical direction, thereby ensuring that the first damping unit assembly as a whole provides damping support to the track unit at the upper end.

[0010] 3、In the application, a main groove body and a secondary groove body are arranged in the movable mounting groove from top to bottom, the supporting base is arranged in the main groove body, and the supporting base has a lateral and vertical buffer stroke space in the main groove body, the guide main shaft at the lower end of the supporting base is arranged for vertical positioning and installation of the whole body, thereby ensuring the positioning and guiding of the whole body during damping and buffering, and the two damping devices arranged symmetrically at an angle provide damping support to the supporting base in the lateral direction, and the vertical damping unit and the two symmetrical lateral auxiliary damping units cooperate to provide damping, thereby ensuring the stability of the whole damping.

[0011] 4. In this invention, by providing a connected sliding groove at the lower end of the sub-groove body, and making the diameter of the sliding groove smaller than the diameter of the sub-groove body, when the bottom of the guide spindle is placed in the sliding groove, the guide spindle can have a certain buffer stroke function under the guiding action in the sliding groove. Furthermore, the shock-absorbing spring in the sub-groove body is sleeved on the guide spindle, and under the limiting action between the limiting plate and the bottom plate of the sub-groove body, it provides a motion mechanism for the guide spindle to extend and retract vertically and buffer.

[0012] 5. In this invention, by symmetrically arranging two protective plates along the transverse direction of the sleeper on the support base, and by setting a limiting step at the upper end of the main groove body to be compatible with the two protective plates, the gap and space reserved by the support base during the buffer offset process can be effectively protected by the two protective plates. This reduces the contamination of the components in the movable mounting groove, improves protection, and results in a longer service life.

[0013] 6. In this invention, a second damping unit assembly is installed between two adjacent sleepers, with the damping main shaft providing direct buffer support to the two sleepers. Inclined support rods support the upper support plate, and the two inclined support rods are connected by a horizontal damping sub-shaft. Symmetrical inclined support connecting rods are hinged between the damping sub-shaft and the damping main shaft support. Thus, when the damping main shaft is compressed, the rotation of the two symmetrical inclined support rods causes the support plate to lift. At this time, the inclined support connecting rods exert a downward force on the damping sub-shaft, causing it to compress and descend. Under the force of the damping sub-shaft, the rotation of the two symmetrical inclined support rods cancels out the lifting force on the support plate, keeping it at the same horizontal position to stably support the guide rail unit. Therefore, after damping the two adjacent sleepers, stable support of the support plate on the same horizontal plane is achieved, ensuring stable support and damping effect between multiple track units.

[0014] 7. In this invention, by intersecting the extension line of the central axis of the inclined support rod with the extension line of the central axis of the inclined support connecting rod, the force between the inclined support rod and the inclined support connecting rod can maintain the stable position of the two symmetrical inclined support rods, thereby achieving stable horizontal support of the track unit by the support plate at the same height.
