[0002] The shock absorption device for subway track laying is a device designed to reduce the vibration and noise effects of subway trains on the track structure and the surrounding environment during operation. The shock absorption device mainly absorbs and disperses the vibration energy generated by train operation by adding elastic elements to the track structure and using the deformation of these elements, so as to achieve the effect of shock absorption and noise reduction.

[0003] In the shock absorption device, the elastic element is generally composed of a shock absorption rubber pad, which is also an important elastic element in the shock absorption device. It is usually made of rubber material, and the principle of its shock absorption lies in its unique viscoelastic property. The coiled long-chain molecular structure of rubber and the secondary forces existing between molecules enable the rubber material to undergo reversible large deformations when subjected to external forces, and absorb and disperse vibration energy. At the same time, the hysteresis and internal friction characteristics of rubber further enhance its shock absorption effect. However, in the existing shock absorption devices, the shock absorption rubber pads are generally separate synthetic rubber shock absorption pads, which are troublesome to maintain and replace, have poor shock absorption performance, and cannot provide lateral shock absorption effect. Therefore, a shock absorption device for subway track laying and a shock absorption rubber pad thereof are provided to solve the above problems. Content of the Utility Model

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The embodiments of the present application provide a shock-absorbing device for subway track laying and its shock-absorbing rubber pad, solving the problem that in the existing shock-absorbing devices, the shock-absorbing rubber pad generally uses a separate synthetic rubber shock-absorbing pad, with poor shock-absorbing performance and unable to provide lateral shock-absorbing effect. Therefore, a shock-absorbing device for subway track laying and its shock-absorbing rubber pad are specifically provided to solve the above problems.

[0025] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0026] The embodiments of the present utility model disclose a shock-absorbing device for subway track laying and its shock-absorbing rubber pad.

[0027] According to the appendix Figure 1-8As shown in the figure, it includes a shock-absorbing rubber component 1. The shock-absorbing rubber component 1 includes a composite rubber part 11. The composite rubber part 11 includes a composite rubber plate 111, a rubber bottom frame 112, and a conical rubber block 113. The composite rubber plate 111 is fixedly connected to the top of the conical rubber block 113, and the rubber bottom frame 112 is fixedly connected to the bottom of the conical rubber block 113. The composite rubber plate 111 is slidably connected within the rubber bottom frame 112. The composite rubber plate 111 provides a comprehensive shock-absorbing effect in both the horizontal and vertical directions for this shock-absorbing rubber pad. The setting of the conical rubber block 113 provides a space margin in the vertical direction for this shock-absorbing rubber pad and provides a shock-absorbing effect in the vertical direction. The presence of rubber grooves on both sides of the rubber bottom frame 112 can increase the flexure and shear deformation ability of the composite rubber part 11, thereby improving its shock-absorbing effect. Through three rubber parts with different effects, this shock-absorbing rubber pad has a good seismic shock-absorbing effect in different directions.

[0028] The composite rubber plate 111 includes a rubber protective layer 1111, a rubber layer 1112, and a steel plate layer 1113. The rubber layer 1112 and the steel plate layer 1113 are provided in multiple layers, and each layer of the rubber layer 1112 and the steel plate layer 1113 are fixedly connected to each other within the rubber protective layer 1111 in sequence. This type of composite rubber plate 111 has a certain hardness and horizontal shear resistance by adding the steel plate layer 1113. This kind of composite rubber plate 111 is widely used and is applied in many bridges and high-rise buildings.

[0029] The shock-absorbing rubber component 1 further includes a shock-absorbing fixing part 12. The shock-absorbing fixing part 12 includes a rail fixing seat 121. The rail fixing seat 121 is movably clamped within the composite rubber part 11. The rail fixing seat 121 is provided with a threaded hole 1211. The shock-absorbing fixing part 12 is established between the shock-absorbing rubber component 1 and the rail. It not only provides an upper fixing part for the shock-absorbing rubber component 1 but also undertakes the task of fixing the rail, preventing the rail from loosening above the shock-absorbing rubber component 1, so as to avoid poor shock-absorbing effect, and can also undertake another part of the elastic seismic effect.

[0030] The shock-absorbing fixing part 12 further includes an elastic clamp 122, a fixing bolt 123, and an insulating baffle 124. One end of the elastic clamp 122 abuts against the insulating baffle 124, and the fixing bolt 123 is arranged within the elastic clamp 122. The presence of the elastic clamp 122 enables the shock-absorbing fixing part 12 to have a certain shock-absorbing effect. It enables the rail to quickly return to its position and gives the rail a fixed supporting force.

[0031] The side end of the insulating baffle 124 abuts against the rail fixing seat 121. The fixing bolt 123 is threadedly connected to the threaded hole 1211. The elastic clamp 122 is fixedly connected to the top end of the rail fixing seat 121. The function of the insulating baffle 124 is to block the signal transmission of the rail, prevent accidents from occurring, and at the same time play a role in fixing the rail.

[0032] It includes a shock-absorbing seat 2. The shock-absorbing rubber assembly 1 is arranged inside the shock-absorbing seat 2. The shock-absorbing seat 2 fixes the shock-absorbing rubber assembly 1 to prevent it from loosening and reduces the influence of the external environment on the shock-absorbing rubber assembly 1.

[0033] A cover 21 is movably hinged to the front end of the shock-absorbing seat 2. A small fastening bolt 22 is arranged on the cover 21. The small fastening bolt 22 is threadedly connected inside the shock-absorbing seat 2. A groove 23 is formed at the top end of the shock-absorbing seat 2. The end of the elastic clamp 122 abuts against the groove 23. When the composite rubber part 11 needs to be replaced, the cover 21 can be opened for replacement, making the shock-absorbing rubber pad easy to replace.

[0034] In summary, the above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
