Description
Technical Field
[0001] This utility model relates to the technical field of rubber shock absorbers for rail transit, and in particular to a rubber shock absorber for rail transit with embedded damping particles. Background Technology
[0002] By utilizing the high elasticity and viscoelasticity of rubber, the vibration and impact energy generated during vehicle operation is converted into the elastic deformation energy of the rubber, thereby achieving the purpose of shock absorption. Rubber shock absorbers are often used in rail transit. Rubber shock absorbers are mainly laid between the track and the track bed to absorb and disperse track vibration energy and reduce the propagation of vibration to the surrounding area. They are generally made of rubber materials and have good elasticity and durability.
[0003] In the existing technology, rubber shock absorbers are mostly large units. When the rubber shock absorber is damaged, the whole unit needs to be replaced, which increases the replacement cost. Secondly, since the main body of the current rubber shock absorber is made of rubber, the shock absorption effect is limited and the service life is difficult to extend. Utility Model Content
[0004] The purpose of this utility model is to provide a rail transit rubber shock absorber with embedded damping particles, in order to solve the problems mentioned in the background art, which require the entire rubber shock absorber to be replaced when the rubber shock absorber is damaged, thus increasing the replacement cost. Furthermore, since the main body of the current rubber shock absorber is made of rubber, the shock absorption effect is limited and the service life is difficult to extend.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a rubber shock absorber mechanism, comprising a rubber damping pad, a splicing groove, an embedded groove, an embedded rubber plate, and a damping particle body. The outer wall of the rubber shock absorber mechanism is provided with a splicing mechanism, which includes a first splicing block, a first threaded groove, a second splicing block, and a second threaded groove. The interior of the rubber shock absorber mechanism is provided with a reinforcing component, which includes a first reinforcing metal plate, a first mounting groove, a second reinforcing metal plate, a second mounting groove, a long screw, and a short screw.
[0006] In a preferred embodiment, the rubber shock absorber has splicing grooves on one side and the side perpendicular to it, and an embedded groove is formed inside the rubber shock absorber.
[0007] In a preferred embodiment, the inner wall of the embedded groove is fixedly connected to the outer wall of the embedded rubber plate, and the inside of the embedded rubber plate is provided with a honeycomb groove, and the inner wall of the honeycomb groove is filled with damping particle body.
[0008] In a preferred embodiment, the side of the rubber shock-absorbing pad away from the splicing groove is fixedly connected to one side of the first splicing block, and the first splicing block has a first threaded groove inside.
[0009] In a preferred embodiment, the side of the rubber shock-absorbing pad perpendicular to the first splicing block is fixedly connected to one side of the second splicing block, and the second splicing block has a second threaded groove inside.
[0010] In a preferred embodiment, the inner wall of the splicing groove is fixedly connected to the outer wall of the first reinforcing metal plate, and the first reinforcing metal plate is arranged parallel to the first splicing block.
[0011] In a preferred embodiment, the top of the first reinforcing metal plate is provided with a first mounting groove, and the inner wall of the other side of the splicing groove is fixedly connected to the outer wall of the second reinforcing metal plate, and the top of the second reinforcing metal plate is provided with a second mounting groove.
[0012] In a preferred embodiment, the inner wall of the second mounting groove is movably connected to the outer wall of the long screw, and the outer wall of the long screw is threadedly connected to the inner wall of the second threaded groove. The inner wall of the first mounting groove is movably connected to the outer wall of the short screw, and the outer wall of the short screw is threadedly connected to the inner wall of the first threaded groove.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, when some rubber shock-absorbing pads are damaged, tools are used to remove the long and short screws, so that the long and short screws are respectively away from the inner walls of the second and first threaded grooves, thereby freeing the first and second splicing blocks from the locked state. The damaged rubber shock-absorbing pads are then removed, and new rubber shock-absorbing pads are placed at the splicing point. At the same time, the first and second splicing blocks are respectively inserted into the interiors of the first and second reinforcing metal plates. Then, the long and short screws are respectively placed into the interiors of the second and first mounting grooves. Tools are used to rotate the long and short screws, so that the long and short screws are respectively inserted into the interiors of the second and first threaded grooves, thereby locking the second and first splicing blocks. Through the modular design of the rubber shock-absorbing pads, when some rubber shock-absorbing pads are damaged, the device can be partially replaced, reducing maintenance costs.
[0015] 2. In this utility model, the rubber damping pad is laid between the track and the ballast bed. When the vehicle travels over the track, the damping particles can convert vibration energy into heat energy and other forms of energy through their own movement, mutual collision, and friction with the rubber damping pad and the embedded rubber plate. This effectively dissipates vibration, improves the damping performance of the device, and provides a smoother operating environment for rail transit vehicles. By dissipating vibration energy through the damping particles, the stress and fatigue damage borne by the rubber damping pad and the embedded rubber plate are reduced, thereby extending the overall service life of the device.
