Description

Technical Field

[0001] The utility model relates to the technical field of sleeper rubber pads, in particular to a sleeper rubber pad with a shoulder stop. Background Art

[0002] The shoulder-blocking rubber pad is a rubber pad used for shock absorption and protection under the railway sleeper. It is located between the railway sleeper and the track foundation, and plays the role of buffering, shock absorption and load dispersion. This rubber pad is usually made of rubber material, with good elasticity and durability, which can effectively reduce track vibration and noise, and extend the service life of railway tracks and sleepers. The shoulder-blocking rubber pad plays an important role in railway track engineering, improving the safety and comfort of railway transportation.

[0003] The movement effect in the traditional rubber pads of sleepers with shoulders is mainly achieved by several key components. The first is the rubber pad, which is made of elastic material and can be compressed, squeezed or squeezed out when the train passes, thereby absorbing and dispersing the vibration and impact force generated by the train. The second is the sleeper, as a structure supporting the track and rails, it supports the rubber pad and affects its movement effect. Some designs can even provide more elasticity and vibration absorption capacity. The rails, as the tracks on which the trains travel, are directly affected by the movement effect of the rubber pads. A good design can reduce the impact between the trains and reduce noise and vibration.

[0004] However, conventional rubber pads for sleepers with shoulder pads usually rely on the pressure of the train to achieve adaptability in terms of shoulder pads. However, despite being able to achieve adaptability, their rigidity is often insufficient. This adaptability means that the shoulder pads can deform and adjust according to the weight and force generated by the movement of the train to adapt to different situations and conditions, thereby reducing the impact on the track and the train. However, due to the elasticity and softness of the shoulder pads themselves, their lack of rigidity may result in insufficient support and stability in some cases, especially when high-speed trains or heavy-load trains pass by. Therefore, a rubber pad for sleepers with shoulder pads is proposed to solve the above problem. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2The utility model provides an embodiment: a rubber pad for a sleeper with a shoulder, comprising an outer shell 1, a rotating column 5 is rotatably connected inside the outer shell 1, a handle 4 is fixedly connected to the outer wall of the rotating column 5, a threaded rod 8 is fixedly connected to one end of the rotating column 5, a first fixed column 9 is fixedly connected to one end of the threaded rod 8, a connecting ring 7 is threadedly connected to the outer wall of the threaded rod 8, a first connecting block 6 is fixedly connected to the outer wall of the connecting ring 7, and a wedge block 2 is fixedly connected to the top of the first connecting block 6.

[0032] Specifically, when using a sleeper rubber pad with a shoulder stop, first manually turn the handle 4, and the handle 4 is forced to drive the rotating column 5 to rotate. Subsequently, the threaded rod 8 at one end is driven to start rotating by the rotation of the rotating column 5. The movement of the threaded rod 8 then drives the first fixed column 9 to rotate. Subsequently, the rotation of the threaded rod 8 also drives the connecting ring 7 to start moving. The movement of the connecting ring 7 then drives the first connecting block 6 and the wedge block 2 to start moving. This series of actions achieves the purpose of manually controlling the width of the wedge block 2. In this way, the width of the wedge block 2 can be adjusted, thereby changing the shoulder stop height of the sleeper rubber pad to adapt to different usage requirements and working environments.

[0033] Reference Figure 1 and Figure 3 A second fixing column 11 is fixedly connected inside the shell 1, a fixing block 12 is fixedly connected to the outer wall of the second fixing column 11, a collar 17 is slidably connected to the outer wall of the second fixing column 11, a second spring 16 is provided on one side of the collar 17, a third connecting block 15 is fixedly connected to the outer wall of the collar 17, a connecting rod 14 is fixedly connected to the top of the third connecting block 15, a second connecting block 13 is rotatably connected to the top of the connecting rod 14, a slider 3 is fixedly connected to the top of the second connecting block 13, a damping rod 10 is provided at the bottom of the wedge block 2, a fixing block 12 is fixedly connected to the bottom of the damping rod 10, and a collar 17 is slidably connected to the outer wall of the second fixing column 11.

[0034] Specifically, subsequently, the slider 3 is subjected to pressure, which causes the wedge block 2 to move. The movement of the wedge block 2 drives the slider 3 to continue to move. The force applied to the wedge block 2 causes the damping rod 10 at the bottom to contract. Subsequently, the force applied to the slider 3 causes the second connecting block 13 and the connecting rod 14 at the bottom to start moving. The movement of the connecting rod 14 drives the third connecting block 15 at the bottom to move, thereby pushing the collar 17 to move. The movement of the collar 17 causes the second spring 16 to be squeezed. At the same time, the second fixed column 11 in the housing 1 provides support, allowing the fixed block 12 and the collar 17 to slide along the outer wall of the second fixed column 11. This series of actions together achieves a shock-absorbing effect and ensures the stability and reliability of the device during operation.

[0035] Reference Figure 2 A support plate 18 is fixedly connected to the outer wall of the first fixing column 9 .

[0036] Specifically, the support plate 18 is then firmly fixed inside the housing 1, thereby effectively supporting and stabilizing the threaded rod 8. This design ensures the stability and reliability of the threaded rod 8 during movement, and provides reliable support and guarantee for the normal operation of the entire device.

[0037] Working principle: when using a sleeper rubber pad with shoulder stopper, first manually turn the handle 4, the handle 4 is forced to drive the rotating column 5 to rotate, then the rotation of the rotating column 5 drives the threaded rod 8 at one end to rotate, and then the rotation of the threaded rod 8 drives the first fixed column 9 to rotate, then the rotation of the threaded rod 8 drives the connecting ring 7 to move, and the movement of the connecting ring 7 drives the first connecting block 6 and the wedge block 2 to move, so as to achieve the effect of manually controlling the width of the wedge block 2, and then the support plate 18 is fixed inside the shell 1, so as to achieve the effect of supporting the threaded rod 8, and then the slider 3 is subjected to pressure, with The movable wedge block 2 moves, and then the movement of the wedge block 2 drives the slider 3 to move. The wedge block 2 is forced to drive the damping rod 10 at the bottom to contract. Then the slider 3 is forced to drive the second connecting block 13 and the connecting rod 14 at the bottom to move. The movement of the connecting rod 14 drives the third connecting block 15 at the bottom to move. The movement of the third connecting block 15 causes the ring 17 to move. Then the movement of the ring 17 drives the second spring 16 to be squeezed, and then it is supported by the second fixed column 11 inside the shell 1, and at the same time, the fixed block 12 and the ring 17 slide the outer wall of the second fixed column 11, thereby achieving a shock absorbing effect.
