Detailed implementation manners

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] The positive direction of the X-axis is the front, the negative direction of the X-axis is the rear, the positive direction of the Y-axis is the left, the negative direction of the Y-axis is the right, the positive direction of the Z-axis is the upper, and the negative direction of the Z-axis is the lower.

[0020] As Figures 1 to 4 and Figure 6 shown, the high-damping fastener device for urban rail transit according to the embodiment of the present invention is applied to a sleeper 1. The high-damping fastener device for urban rail transit includes a baseplate assembly 2, a shim block 3, a water diversion assembly 4, mounting bolts 5, a connecting seat 6, and a spring clip 7. The baseplate assembly 2 includes a damping baseplate 13, a height-adjusting baseplate 25, and a rail baseplate 28. The damping baseplate 13 can be made of a rubber material. Mounting bolts 5 are respectively arranged on the left and right sides of the rail baseplate 28 and the rail baseplate 28 is mounted on the sleeper 1 through the mounting bolts 5. A rail 31 is arranged on the damping baseplate 13. Two shim blocks 3 are provided. The two shim blocks 3 are respectively buckled on the left and right sides of the rail 31. A connecting seat 6 is respectively arranged on the left and right sides of the rail 31, and a spring clip 7 is connected to each connecting seat 6. The spring clip 7 is buckled on the shim block 3, that is, the spring clip 7 can be used to absorb the vibration generated during the driving of the vehicle on the rail 31, and reduce the vehicle vibration and noise. Secondly, by arranging the water diversion assembly 4 on the shim block 3, when it rains, the water diversion assembly 4 can centrally collect the rainwater falling on the rail 31 and centrally discharge the rainwater to a position far from the rail 31, which can prevent the rainwater containing conductive substances from penetrating between the rail 31 and the baseplate assembly 2, thereby preventing the leakage of current into the ground to form stray current, reducing the serious current corrosion effect on the steel bar structure of the subway tunnel body, buried metal components and pipeline facilities, etc., and being beneficial to ensuring the safety of building facilities.

[0021] In this embodiment, the two shim blocks 3 are located in the middle of the damping baseplate 13 and are used to buckle the left and right sides of the rail 31 erected on the damping baseplate 13. On the rail baseplate 28 on the left side of the rail 31, the connecting seat 6 is located in front of the mounting bolt 5, and on the rail baseplate 28 on the right side of the rail 31, the connecting seat 6 is located behind the mounting bolt 5.

[0022] Optionally, as Figure 1 , Figure 4 and Figure 5As shown in the figure, to ensure the effectiveness of the rainwater diversion component 4 in collecting and discharging rainwater, the rainwater diversion component 4 includes a water accumulation hopper 8 and a drainage channel 9. The lower end of the water accumulation hopper 8 is connected to the distance adjustment block 3. The upper end of the water accumulation hopper 8 extends towards the side close to the railway track 31, and the water accumulation hopper 8 is located above the rail foot of the railway track 31. An upper-opening water accumulation groove 10 is formed in the water accumulation hopper 8. Specifically, when the water accumulation groove 10 is relatively shallow, excessive rain may cause rainwater to flow out from the edge of the water accumulation groove 10 and fall onto the railway track 31. By recessing the bottom surface of the water accumulation groove 10 downward, it is convenient to collect more rainwater. When it rains heavily, there is still enough space to collect rainwater, thus avoiding rainwater leakage and outflow. The drainage channel 9 is connected to the base plate assembly 2 and is located on one side of the railway track 31. Specifically, the drainage channel 9 is arranged in a long strip shape and extends in the front-back direction. The front and rear ends of the drainage channel 9 are respectively located outside the front and rear ends of the base plate assembly 2. An upper-opening drainage groove is formed in the drainage channel 9, and the front and rear ends of the drainage groove are open. The lower end of the water accumulation groove 10 is used to communicate with the drainage groove. One side of the water accumulation groove 10 collects the rainwater falling on the railway track 31, and on the other side, the rainwater slides along the bottom surface of the water accumulation groove 10 under the influence of gravity and slides from the lower end of the water accumulation groove 10 to above the drainage groove, thus falling onto the drainage groove and then being discharged from the front and rear ends of the drainage groove. This can keep the rainwater away from the railway track 31, thus ensuring the effectiveness of the rainwater diversion component 4 in concentrating and discharging rainwater.

[0023] In this embodiment, two drainage channels 9 and two water accumulation hoppers 8 can be provided. That is, a drainage channel 9 is provided on the left side of the tie plate 28, and a water accumulation hopper 8 is connected to the left distance adjustment block 3; another drainage channel 9 is provided on the right side of the tie plate 28, and another water accumulation hopper 8 is connected to the right distance adjustment block 3, corresponding the water accumulation hopper 8 with the drainage channel 9 on the same side. Thus, by connecting water accumulation hoppers 8 to both the left and right distance adjustment blocks 3, the rainwater on both the left and right sides of the railway track 31 can be collected by the two water accumulation hoppers 8, and by providing drainage channels 9 on both the left and right sides of the tie plate 28, the rainwater in the two water accumulation hoppers 8 can be discharged to the front and rear sides of the railway track 31.

[0024] Optionally, as Figure 1 and Figure 2As shown, to avoid excessive water accumulation in front of or behind the rail 31. The bottom surface of the drainage trough gradually decreases in height from the middle to the ends, and the height of the middle of the bottom surface of the drainage trough is greater than the heights of the front and rear ends of the drainage trough. For example, the bottom surface of the drainage trough can be set to gradually decrease in height from front to back, so that the water in the drainage channel 9 is discharged through the opening at the rear end of the drainage trough under the influence of gravity, that is, the rainwater is concentrated and discharged behind the rail 31, which easily causes excessive water accumulation behind the rail 31. Similarly, the bottom surface of the drainage trough can be set to gradually decrease in height from back to front, so that the water in the drainage channel 9 is discharged through the opening at the front end of the drainage trough under the influence of gravity, that is, the rainwater is concentrated and discharged in front of the rail 31, which easily causes excessive water accumulation in front of the rail 31. When the water accumulation is excessive and the water level is too high, it is easy for rainwater to seep between the rail 31 and the elastic cushion plate. By setting the bottom surface of the drainage trough to have a greater height in the middle than at the front and rear ends, that is, the bottom surface of the drainage trough forms two slopes 11. On the one hand, it is convenient for rainwater to flow along the slopes 11. On the other hand, it can facilitate the rainwater in the drainage trough to flow evenly to the front and rear sides, which is beneficial to avoiding the concentrated discharge of rainwater to the front or rear side of the rail 31 and causing water accumulation.

[0025] Optionally, as Figure 1 and Figure 5 shown, due to space limitations, it is often difficult for the water accumulation hopper 8 to be directly connected to the drainage channel 9, so it is difficult for the rainwater in the water accumulation trough 10 to accurately flow into the drainage trough. To facilitate the accurate introduction of the rainwater in the water accumulation trough 10 into the drainage trough. The water diversion assembly 4 further includes a water diversion channel 12. The upper end of the water diversion channel 12 is connected to the lower end of the water accumulation hopper 8. Specifically, the water diversion channel 12 can be connected or glued to the water accumulation hopper 8 by bolts. The lower end of the water diversion channel 12 extends above the drainage trough. A water diversion groove is provided in the water diversion channel 12, and the water diversion groove is inclined downward. The upper end of the water diversion groove is communicated with the water accumulation trough 10, so that the rainwater in the water accumulation trough 10 can only flow into the drainage trough from the water diversion groove under the influence of gravity, which is beneficial to limiting the flow trajectory of the rainwater and preventing rainwater leakage.

[0026] In this embodiment, one water diversion channel 12 can be provided, which is connected or glued to the middle of the lower end of the water accumulation hopper 8 by bolts, and the lower end of the water diversion channel 12 is aligned with the middle of the drainage trough. Then the rainwater in the water accumulation trough 10 can enter the middle of the drainage trough through the water diversion channel 12, which can ensure that the rainwater flows evenly to the front and rear sides. Secondly, two water diversion channels 12 can also be provided, and the two water diversion channels 12 are respectively corresponding to the front and rear sides of the drainage trough. Then the two water diversion channels 12 respectively introduce the water in the water accumulation trough 10 into the front and rear sides of the drainage trough, which can also ensure that the rainwater flows evenly to the front and rear sides.

[0027] Optionally, as Figure 2 、 Figure 3 andFigure 5 As shown, when rainwater or other accumulated water has seeped between the rail 31 and the vibration damping pad 13, in order to remove the rainwater between the rail 31 and the vibration damping pad 13, the pad assembly 2 includes a vibration damping pad 13, a chute 14 and a communication groove 15. The vibration damping pad 13 is located at the lower end of the rail 31. A plurality of chutes 14 are formed in the vibration damping pad 13. The chute 14 is arranged as a cylindrical groove, and the upper end of the cylindrical groove is open. Then, the rainwater between the rail 31 and the vibration damping pad 13 can flow along the inner wall of the chute 14 under the influence of gravity. The plurality of chutes 14 are spaced apart in the left-right direction, and the axial directions of the plurality of chutes 14 all face the front-back direction. A communication groove 15 extending in the left-right direction is formed in the vibration damping pad 13. The height of the communication groove 15 gradually decreases during the extension from the left end to the right end. Specifically, the height of the left end of the communication groove 15 is greater than that of the right end. The left end of the communication groove 15 sequentially passes through the plurality of chutes 14. Then, the rainwater gradually flows from the chute 14 with a higher height to the chute 14 with a lower height through the communication groove 15. The right end of the communication groove 15 is connected to a drainage pipe 16. The drainage pipe 16 is inclined downward. The lower end of the drainage pipe 16 is located above the drainage groove and is used to communicate with the drainage groove. When the rainwater flows to the rightmost chute 14, it then enters the right drainage groove through the drainage pipe 16, which is beneficial to discharging the rainwater between the rail 31 and the vibration damping pad 13 through the drainage groove. Thus, by providing a plurality of chutes 14 and a communication groove 15, it is convenient to discharge the rainwater or other accumulated water between the rail 31 and the vibration damping pad 13.

[0028] In this embodiment, the plurality of chutes 14 are equally spaced in the left-right direction. The communication groove 15 is located in the middle of the vibration damping pad 13, and the right end of the communication groove 15 passes through the vibration damping pad 13 and is inclined downward.

[0029] Optionally, as Figure 3As shown in the figure, to facilitate the removal of rainwater or accumulated water in the sliding groove 14, the backing plate assembly 2 further includes a slider 17 and a handle 18. The slider 17 is configured to be disposed in the sliding groove 14 and is slidably connected to the sliding groove 14 in the front-rear direction. Specifically, by using the movement of the slider 17 in the sliding groove 14, the rainwater in the sliding groove 14 can be squeezed towards the communication groove 15. Since the communication groove 15 communicates with multiple sliding grooves 14, the rainwater can enter the adjacent sliding groove 14 through the communication groove 15. In the order from high to low of the communication groove 15, that is, by sequentially pushing the sliders 17 in different sliding grooves 14 from left to right, the rainwater can enter the sliding groove 14 with the lowest height at the right end and enter the drainage groove through the drainage pipe 16. The handle 18 is connected to the slider 17 and is located outside the sliding groove 14. Since the space in the sliding groove 14 is limited, it is difficult for the staff to reach into the sliding groove 14 to push the slider 17. By providing the handle 18 connected to the slider 17 and disposing the handle 18 outside the sliding groove 14, it is convenient for the staff to contact the handle 18, which is beneficial to pushing the slider 17 and pulling the slider 17 to reset.

[0030] In this embodiment, the slider 17 is arranged as a columnar structure having the same shape as the sliding groove 14. Specifically, it is a cylindrical structure and the upper end surface is a plane. Sliders 17 are arranged on both the front and rear sides of the sliding groove 14. By using the movement of the front and rear sliders 17 in the sliding groove 14, it is convenient to push the rainwater in the sliding groove 14 towards the central communication groove 15.

[0031] Optionally, as Figure 3 shown, to reduce the burden on the staff. The backing plate assembly 2 further includes an elastic member 19. The elastic member 19 is installed in the sliding groove 14 and is used to drive the slider 17 to reset. Specifically, the elastic member 19 is installed in the middle of the sliding groove 14. When the slider 17 moves in the sliding groove 14 to the elastic member 19, under the action of the elastic member 19, the slider 17 is pushed to move in the reverse direction to reset.

[0032] In this embodiment, the elastic member 19 includes a positioning plate 20 and a spring 21. The positioning plate 20 is located in the sliding groove 14 and is connected to the inner wall of the sliding groove 14. Specifically, the positioning plate 20 is arranged as a disc shape and the upper end surface is a plane. There are two springs 21. The two springs 21 are respectively connected to the positioning plate 20 in a front-rear linkage manner. The springs 21 are coaxially distributed with the sliding groove 14. The front and rear sliders 17 respectively abut against the two springs 21. When the front and rear sliders 17 move towards the middle in the sliding groove 14, that is, the front slider 17 moves backward and the rear slider 17 moves forward, the front slider 17 pushes the front spring 21 to be compressed, and the rear slider 17 pushes the rear spring 21 to be compressed. After the thrust on the front slider 17 and the rear slider 17 is removed, the front spring 21 extends and pushes the front slider 17 to move forward until it resets, and the rear spring 21 extends and pushes the rear slider 17 to move backward until it resets.

[0033] Optionally, as Figure 3 and Figure 7 shown, to prevent accidental contact with the handle 18 from pushing rainwater or accumulated water in the chute 14 to the side away from the drainage pipe 16. The backing plate assembly 2 further includes a baffle 22. The handle 18 includes a connecting rod 23 and a pushing block 24. The connecting rod 23 is arranged in a cylindrical structure, and the pushing block 24 is arranged in a disc shape with a flat upper end face. Specifically, at the front side of the chute 14, the rear end of the front connecting rod 23 is connected to the front slider 17, and the front end is connected to the front pushing block 24; at the rear side of the chute 14, the front end of the rear connecting rod 23 is connected to the rear slider 17, and the rear end is connected to the rear pushing block 24. Since there are multiple chutes 14 arranged from left to right, starting from the left to the right, a baffle 22 is connected to the pushing block 24. Specifically, at the front side of the chute 14, the baffle 22 is located at the rear side of the adjacent right pushing block 24; at the rear side of the chute 14, the baffle 22 is located at the front side of the adjacent right pushing block 24. Then, it is more labor-saving to push the pushing blocks 24 in sequence from left to right, which is convenient for pushing rainwater or accumulated water to the drainage pipe 16. When pushing the pushing block 24 from right to left, however, it is necessary to push the baffle 22, multiple left pushing blocks 24, and multiple left springs 21 at the same time, which is more laborious. Thus, accidental contact with the right pushing block 24 can be avoided from pushing rainwater or accumulated water in the chute 14 to the side away from the drainage pipe 16.

[0034] Optionally, as Figures 2 to 7 shown, to prevent the slider 17 from sliding randomly in the chute 14 and causing wear. The damping backing plate 13 further includes a height-adjusting backing plate 25, a slide rail 26, a clamping member 27, and an iron backing plate 28. The height-adjusting backing plate 25 is located at the lower end of the damping backing plate 13 and above the iron backing plate 28, and it can be used to pad the height of the slide rail 31. The iron backing plate 28 is assembled on the sleeper 1 through the mounting bolts 5. The slide rail 26 extends in the vertical direction. The lower end of the clamping member 27 is slidably connected to the slide rail 26, and the lower end of the clamping member 27 is mutually matched in shape and size with the slider 17, so that the lower end of the clamping member 27 is in interference fit with the slide rail 26. The upper end of the clamping member 27 is used to connect with the pushing block 24, and a clamping groove is formed at the lower end of the pushing block 24. The upper end of the clamping member 27 is used to insert into the pushing block 24. Thus, by adjusting the position of the lower end of the clamping member 27 relative to the slide rail 26, the upper end of the clamping member 27 is connected to the pushing block 24, so that the slider 17 cannot move forward or backward.

[0035] In this embodiment, a set of slide rails 26 and clamping members 27 are provided on both the front and rear sides of the height-adjusting pad 25. Specifically, the front clamping member 27 is used to connect the front pushing block 24 to limit the front slider 17, and the rear clamping member 27 is used to connect the rear pushing block 24 to limit the rear slider 17. Specifically, the clamping member 27 includes a sliding block 29 and a clamping post 30. A clamping groove is formed at the lower end of the baffle 22. When it is necessary to drive the pushing block 24, the sliding block 29 is slid downward in the slide rail 26 until the clamping post 30 disengages from the clamping groove. When it is not necessary to drive the pushing block 24, the sliding block 29 is slid upward in the slide rail 26 until the clamping post 30 is inserted into the clamping groove.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
