Description

Technical Field

[0001] This invention relates to the field of track vibration damping pad installation technology, and in particular to a subway track laying device and a vibration damping rubber sheet. Background Technology

[0002] To reduce train noise and vibration, pads are currently laid between the rails and sleepers to absorb the vibrations generated when the train runs on the rails. The performance of the pads directly affects the safety and comfort of train operation. The commonly used pads are made of polyester elastic material.

[0003] When using existing automated rail laying vehicles for rail laying, the base plates are placed in the ballast installation slots in advance. During construction, the surface of the base plates may become abnormal due to poor management or construction impacts, such as the presence of gravel on the base plates. Furthermore, with the base plates placed in the installation slots in advance, the inclined rails falling at an angle will inevitably cause the base plates to move, thus affecting the rapid laying of the rails and shock-absorbing base plates. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a subway track laying device and a shock-absorbing rubber plate to solve the problem of the shock-absorbing pad moving when the rail falls into the ballast.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A subway track laying device includes a rail laying vehicle, two suspension beams are fixedly connected to one side of the rail laying vehicle, and multiple rotating rollers with progressively decreasing heights are spaced apart on the upper side of each suspension beam. A support plate is fixedly connected to the end of the suspension beam away from the rail laying vehicle, and two pushing devices are provided on the upper side of the support plate.

[0007] The pushing device includes a box body, with through grooves on opposite sides of the box body. A push plate is slidably connected in the through grooves, and a telescopic rod is fixedly connected to the upper side of the support plate. The telescopic end of the telescopic rod is fixedly connected to the push plate.

[0008] The box contains shock-absorbing panels.

[0009] Preferably, the end of the push plate away from the telescopic rod is rotatably connected to the support plate, and the pivot of the support plate is provided with a torsion spring.

[0010] Preferably, the rotating shaft of the pallet passes through one end of the push plate and is rotatably connected to a cylinder, and a pad is fixedly connected to one side of the push plate. One end face of the pad has a spiral structure, and the cylinder is rolled on the spiral structure.

[0011] The rotating shaft of the pallet is provided with a boss, and a first spring is fixedly connected to one side of the boss. A circular ring is fixedly connected to one end of the first spring, and the circular ring abuts against the side of the push plate.

[0012] Preferably, one end of the push plate is provided with a mounting hole, the inner wall of the mounting hole is provided with a sliding groove, a slider is slidably connected in the sliding groove, and a torsion spring is provided between the slider and the rotating shaft of the support plate.

[0013] Preferably, the thickness of the tray is less than the thickness of the push plate, and the upper end of the box has an open structure with shock-absorbing plates stacked inside.

[0014] The present invention also discloses a subway track vibration damping rubber sheet, which is placed in the box of the above-mentioned laying device. The upper side of the vibration damping sheet is provided with a plurality of strip grooves at intervals, and one end of the bottom of the vibration damping sheet is provided with an arc groove.

[0015] The upper side of the shock-absorbing plate is provided with a slot, which is perpendicular to the strip groove.

[0016] Preferably, the width of the groove opening is smaller than the width inside the groove, and the groove is filled with colloid.

[0017] The advantages of this invention are as follows: The subway track laying device and shock-absorbing rubber plate provided by this invention achieve rapid laying of the rail and shock-absorbing plate by means of the telescopic rod on the upper side of the support plate pushing the shock-absorbing plate pre-stored in the box through the push plate during the inclined sliding of the rail. The shock-absorbing plate is placed in the installation groove of the ballast, thereby achieving high laying efficiency.

[0018] This invention involves placing the damping plate on the upper side of a support plate, and then using a pusher plate to push the damping plate out of the housing. Adhesive is applied to the upper center of the damping plate. After the damping plate is completely separated from the housing, the torsion spring's return rotation causes the damping plate to adhere to the bottom of the rail. This facilitates the intermittent adhesion of damping plates to the bottom of the rail, allowing the rail on the ballast to be cushioned by the damping plates while also facilitating their rapid installation.

[0019] This invention, during the retraction of the push plate, first obstructs the outer side of the box body, widening the gap between the push plate and the support plate. Simultaneously, a pad on one side of the support plate slides relative to the rotating shaft. The spiral structure of the pad presses against the cylinder on the side of the rotating shaft, causing the cylinder to passively roll on the spiral structure to its closest point to the push plate. During this process, the rotating shaft rotates, carrying the support plate back to a state parallel to the through groove. Guide grooves for the support plate are provided on the other two sides of the box body (excluding the through groove). After the support plate is no longer restricted by the side of the box body, a first spring pulls the support plate back into the box body. Simultaneously, the cylinder moves away from the spiral structure from its closest point to the push plate. After the support plate is pushed out of the box body again, the cylinder rotates again to its furthest point from the push plate, allowing for repeated pushing out of the shock-absorbing plate. Furthermore, the rotation of the torsion spring causes the support plate to adhere or press the shock-absorbing plate firmly to the bottom of the rail, thus enabling rapid laying of the shock-absorbing plate in conjunction with rail laying and improving laying efficiency.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] Example 1

[0029] like Figures 1-7 As shown, the present invention provides a subway track laying device, including a rail laying vehicle 1. Two suspension beams 11 are fixedly connected to one side of the rail laying vehicle 1. Multiple rotating rollers 12 with progressively decreasing heights are arranged at intervals on the upper side of each suspension beam 11. The rails are pushed onto the rotating rollers 12 and gradually tilt. The rotating rollers 12 provide friction and guidance. In conjunction with the movement of the rail laying vehicle 1, the rails are laid one by one. The end of the suspension beam 11 away from the rail laying vehicle 1 is fixedly connected to a support plate 13. Two pushing devices 2 are provided on the upper side of the support plate 13.

[0030] The pushing device 2 includes a box body 21. A through groove 22 is provided on both sides of the box body 21. A push plate 23 is slidably connected in the through groove 22. A telescopic rod 24 is fixedly connected to the upper side of the support plate 13. The telescopic rod 24 is a hydraulic rod or an electric push rod. The telescopic end of the telescopic rod 24 is fixedly connected to the push plate 23.

[0031] The box 21 contains a shock-absorbing plate 5.

[0032] This invention involves a rail laying vehicle 1 moving to the position to be laid on already laid rails. The rail to be installed is lowered along the rotating roller 12, and with the retraction of the rail laying vehicle 1, the lowered rail is aligned with the already laid rail, forming a rapid rail laying (existing technology). During the inclined sliding of the rail, the telescopic rod 24 on the upper side of the support plate 13 pushes the shock-absorbing plate 5 pre-stored in the box 21 through the push plate 23. The shock-absorbing plate 5 is placed in the ballast mounting groove 10, realizing the rapid laying of the rail and the shock-absorbing plate 5 with high laying efficiency.

[0033] Example 2

[0034] like Figures 1-7 As shown, the end of the push plate 23 away from the telescopic rod 24 is rotatably connected to the support plate 25, and the pivot 251 of the support plate 25 is provided with a torsion spring 3.

[0035] During operation, the damping plate 5 rests on the upper side of the support plate 25. The push plate 23, along with the support plate 25, pushes the damping plate 5 out of the box 21. Adhesive is applied to the upper middle part of the damping plate 5. After the damping plate 5 is completely separated from the box 21, the torsion spring 3 rotates and resets, causing the damping plate 5 to adhere to the bottom of the rail. This facilitates the spacing of the damping plates 5 on the bottom of the rail, allowing the rail on the ballast to be buffered by the damping plates 5 on one hand, and facilitating the rapid installation of the damping plates 5 on the other.

[0036] Example 3

[0037] like Figures 1-7 As shown, the rotating shaft 251 of the pallet 25 passes through one end of the push plate 23 and is rotatably connected to the cylinder 26. The push plate 23 is fixedly connected to one side of the pad 27. One end face of the pad 27 is a spiral structure surface 271, and the cylinder 26 is rolled on the spiral structure surface 271.

[0038] The rotating shaft 251 of the support plate 25 is provided with a boss 252. A first spring 28 is fixedly connected to one side of the boss 252. A circular ring 29 is fixedly connected to one end of the first spring 28. The circular ring 29 abuts against the side of the push plate 23. The first spring 28 plays the role of axial reset of the rotating shaft 251.

[0039] like Figures 1-7 As shown, one end of the push plate 23 is provided with a mounting hole 4, and the inner wall of the mounting hole 4 is provided with a sliding groove 41. The slider 42 is slidably connected in the sliding groove 41, and the torsion spring 3 is provided between the slider 42 and the rotating shaft 251 of the support plate 25. The slider 42 slides in the sliding groove 41, so that the torsion spring 3 can move with the rotating shaft 251.

[0040] During operation, after the pallet 25 is pushed out of the through slot 22, under the torsion of the torsion spring 3, the pallet 25 rotates to a state of inclination with the rail. When the damping plate 5 is coated with adhesive, the damping plate 5 is attached to the bottom of the inclined rail.

[0041] When the push plate 23 retracts, the support plate 25 is first blocked by the outer side of the box body 21, increasing the distance between the push plate 23 and the support plate 25. The pad 27 on one side of the support plate 25 slides relative to the rotating shaft 251. The spiral structure surface 271 of the pad 27 presses against the cylinder 26 on the side of the rotating shaft 251, causing the cylinder 26 to passively roll on the spiral structure surface 271 to the closest point between the spiral structure surface 271 and the push plate 23. During this process, the rotating shaft 251 rotates and carries the support plate 25 back to a state parallel to the through groove 22. The other two sides of the box body 21, not through groove 22, are provided with guide grooves to cooperate with the support plate 25. After being limited by the side of the box 21, the first spring 28 pulls the support plate 25 back into the box 21. At the same time, the cylinder 26 moves away from the closest point of the spiral structure surface 271 to the push plate 23. After the support plate 25 pushes out of the box 21 again, under the action of the torsion spring 3, the cylinder 26 rotates back to the point of contact with the spiral structure surface 271 and the farthest point from the push plate 23. Thus, the shock-absorbing plate 5 can be pushed out repeatedly. The rotation of the torsion spring 3 causes the support plate 25 to stick or press the shock-absorbing plate 5 to the bottom of the rail. This allows for the rapid laying of the shock-absorbing plate 5 in conjunction with the laying of the rail, improving the laying efficiency.

[0042] Example 4

[0043] like Figures 1-7 As shown, the thickness of the tray 25 is less than the thickness of the pusher plate 23. The upper end of the box 21 has an open structure and the shock-absorbing plates 5 are stacked inside. When the pusher plate 23 pushes out the tray 25, only one shock-absorbing plate 5 is pushed out. The upper shock-absorbing plate 5 first falls on the pusher plate 23. After the shock-absorbing plate 5 extends out of the box 21 and is laid on the tray 25, the pusher plate 23 and the tray 25 retract and reset. Then, the next shock-absorbing plate 5 falls back onto the tray 25, thus forming a periodic laying.

[0044] This invention also discloses a subway track vibration damping rubber sheet, which is placed in the box 21 of the above-mentioned laying device. The upper side of the vibration damping sheet 5 is provided with a plurality of strip-shaped grooves 51 at intervals, and one end of the bottom of the vibration damping sheet 5 is provided with an arc-shaped groove 52. The arc-shaped groove 52 cooperates with the arc-shaped protrusion 20 in the ballast installation groove 10. When the rail is tilted and falling, the arc-shaped groove 52 of the vibration damping sheet 5 fits against the arc-shaped protrusion 20, reducing the sliding of the vibration damping sheet 5 when the rail is installed at an angle. On the one hand, the vibration damping sheet 5 can be installed in place, and on the other hand, the sliding range of the rail is small, which makes it easy to keep the gap between the rail and the already laid rail within the qualified range.

[0045] The upper side of the damping plate 5 is provided with a slot 53, which is perpendicular to the strip groove 51. The slot 53 can hold the damping plate 5 at the bottom of the rail, so that the damping plate 5 is attached to the bottom of the rail and can be accurately dropped into the ballast installation groove 10.

[0046] Furthermore, the width of the groove opening of the strip groove 51 is smaller than the width inside the strip groove 51. For example, the cross-section of the strip groove 51 is a dovetail structure, an inverted "T" shape, or an arc shape. The strip groove 51 is filled with a colloid, such as glass glue. This facilitates the filling of the strip groove 51 with a sticky colloid, and the colloid is filled to two-thirds of the strip groove 51, so that the damping plates 5 can be stacked without sticking to each other. When the damping plates 5 are patted to the bottom of the rail by the support plate 25, the strip groove 51 is pressed as the surface of the damping plates 5 is pressed, and some of the colloid overflows to the surface, thereby forming an adhesive effect. The overflowed colloid corresponds to the strip groove 51 in a strip shape, forming a local adhesive effect between the damping plates 5 and the rail. It is also convenient to separate the damping plates 5 for subsequent maintenance and replacement.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
