Description

Technical Field

[0001] This utility model relates to the field of track vibration reduction technology, specifically to an adaptive vibration reduction structure for rail transit. Background Technology

[0002] Railway tracks, also known as rails, are primarily used on railways and work in conjunction with switches to allow trains to travel without turning. A railway track typically consists of two parallel steel rails fixed to sleepers, beneath which lies the ballast. They are secured by rail braces, fasteners, rail clamps, rail clips, elastic clips, and railway spikes. Made of steel, railway tracks can withstand greater weight than other materials. Sleepers, also called rail sleepers, distribute the weight and pressure of the rails and maintain a fixed track gauge. Originally wooden sleepers, they have been replaced with concrete sleepers. The track bears varying vertical, lateral, and longitudinal static and dynamic loads, which are transferred from the rails through the sleepers and ballast to the roadbed. Through mechanical theory, the stress and strain generated in the various components of the track under various load conditions are analyzed to determine its load-bearing capacity and stability.

[0003] In the current track structure, the rails are fixedly mounted on the pads, and the pads are fixed to the sleepers with screws. Therefore, both the rails and the pads are rigidly fixed, and the track structure does not have the ability to absorb shocks. Therefore, it is necessary to design a track structure with shock absorption function. Utility Model Content

[0004] In view of the problems existing in the current adaptive vibration reduction structure for rail transit, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an adaptive vibration reduction structure for rail transit, which solves the problem that in the current track structure, the rail is fixedly installed on the pad, and the pad is fixedly installed on the sleeper by screws. Therefore, both the rail and the pad are rigidly fixed, and the track structure does not have the performance of vibration reduction. Therefore, it is necessary to design a track structure with vibration reduction function.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] An adaptive vibration reduction structure for rail transit includes a sleeper installed on the track bed. Both ends of the sleeper are provided with buffer through holes. A slider is slidably connected in the buffer through hole. A pad is welded to the top of the slider. A rail is installed on the pad. The pad is installed on the sleeper by long bolts. An arc-shaped buffer plate is provided in the buffer through hole.

[0008] As a preferred embodiment of the adaptive vibration reduction structure for rail transit described in this utility model, the arc-shaped buffer sheet is made of steel, and both ends of the arc-shaped buffer sheet abut against the inner wall of the buffer through hole.

[0009] As a preferred embodiment of the adaptive vibration reduction structure for rail transit described in this utility model, both ends of the rail are bolted with clamps, and the clamps are tightly fitted to the surface of the rail.

[0010] As a preferred embodiment of the adaptive vibration reduction structure for rail transit described in this utility model, the bottom of the sleeper is provided with a steel plate, and the steel plate has through holes for the long bolts to pass through.

[0011] As a preferred embodiment of the adaptive vibration reduction structure for rail transit described in this utility model, the sleeper has a first elongated through hole at both ends for a long bolt to pass through, the long bolt passes through the first elongated through hole, and the width of the first elongated through hole is equal to the diameter of the long bolt.

[0012] As a preferred embodiment of the adaptive vibration reduction structure for rail transit described in this utility model, the sleeper has a second elongated through hole at both ends for a long bolt to pass through. A steel sleeve is embedded in the second elongated through hole, the long bolt passes through the steel sleeve, and the inner width of the steel sleeve is equal to the diameter of the long bolt.

[0013] Compared with existing technologies:

[0014] By setting buffer through holes on the sleeper, an arc-shaped buffer plate and a slider are installed in the buffer through holes. A pad is welded to the top of the slider, and the pad is fixed to the sleeper by a long bolt. The sleeper has an elongated through hole for the long bolt to move. When the steel plate is under stress, the rail is under stress and drives the pad to move. The pad drives the long bolt to move in the first elongated through hole. At the same time, the pad drives the slider to move. The movement of the slider compresses the arc-shaped buffer plate, causing the arc-shaped buffer plate to deform, thereby buffering and damping the movement of the rail. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Example 1:

[0023] This utility model provides an adaptive vibration reduction structure for rail transit. Please refer to [link / reference]. Figure 1-4 The track includes a sleeper 1 set on the track bed. Both ends of the sleeper 1 are provided with buffer through holes 9. A slider 7 is slidably connected in the buffer through holes 9. A pad 2 is welded to the top of the slider 7. A rail 3 is installed on the pad 2. The pad 2 is installed on the sleeper 1 by long bolts 6. Both ends of the rail 3 are bolted with clamps 5. The clamps 5 are tightly fitted to the surface of the rail 3. An arc-shaped buffer plate 8 is provided in the buffer through hole 9.

[0024] The arc-shaped buffer plate 8 is made of steel, and both ends of the arc-shaped buffer plate 8 abut against the inner wall of the buffer through hole 9.

[0025] The bottom of the track sleeper 1 is provided with a steel plate 4, and the steel plate 4 has a through hole for the long bolt 6 to pass through. The nut on the long bolt 6 is pressed against the steel plate 4.

[0026] Both ends of the sleeper 1 are provided with first elongated through holes 10 for long bolts 6 to pass through. The width of the first elongated through hole 10 is equal to the diameter of the long bolt 6. Thus, when the steel plate 4 is under force, the rail 3 is under force and drives the pad 2 to move. The pad 2 drives the long bolt 6 to move within the first elongated through hole 10. At the same time, the pad 2 drives the slider 7 to move. The movement of the slider 7 compresses the arc-shaped buffer plate 8, causing the arc-shaped buffer plate 8 to deform, thereby buffering and damping the movement of the rail 3. Moreover, the distance between the inner wall of the concave surface of the arc-shaped buffer plate 8 and the buffer through hole 9 is less than 2mm. Therefore, the maximum deformation distance of the arc-shaped buffer plate 8 is not greater than 2mm, thereby avoiding excessive movement distance of the rail 3 and ensuring reliable support of the rail 3 for the train.

[0027] In practical use:

[0028] Use long bolts 6 to install pad 2 on sleeper 1, and pass long bolts 6 through pad 2, first long strip through hole 10 and steel plate 4;

[0029] When the steel plate 4 is under force, the rail 3 is under force and drives the pad 2 to move. The pad 2 drives the long bolt 6 to move in the first long strip through hole 10. At the same time, the pad 2 drives the slider 7 to move. The movement of the slider 7 compresses the arc-shaped buffer plate 8, and the arc-shaped buffer plate 8 deforms, thereby buffering and damping the movement of the rail 3.

[0030] Example 2:

[0031] See appendix Figure 5 Unlike Embodiment 1, the track sleeper 1 has a second elongated through hole 11 at both ends for the long bolt 6 to pass through. A steel sleeve 12 is embedded in the second elongated through hole 11, the long bolt 6 passes through the steel sleeve 12, and the inner width of the steel sleeve 12 is equal to the diameter of the long bolt 6.

[0032] In practical use:

[0033] Use long bolts 6 to install pad 2 on sleeper 1, and pass long bolts 6 through pad 2, first long strip through hole 10 and steel plate 4;

[0034] When the steel plate 4 is under stress, the rail 3 is under stress and drives the pad 2 to move. The pad 2 drives the long bolt 6 to move inside the steel sleeve 12. At the same time, the pad 2 drives the slider 7 to move. The movement of the slider 7 compresses the arc-shaped buffer plate 8, causing the arc-shaped buffer plate 8 to deform, thereby buffering and damping the movement of the rail 3.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
