[0025] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0026] According to an embodiment of the utility model, a shock absorbing device for a shield machine is provided.

[0027] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-5 As shown, the shock absorbing device for a shield machine according to an embodiment of the utility model comprises a shock absorbing box body 1, a vertical shock absorbing mechanism 2 is arranged inside the shock absorbing box body 1, a receiving box 3 is arranged at the top of the vertical shock absorbing mechanism 2, a horizontal shock absorbing mechanism 4 is arranged inside the receiving box 3, and a shield machine contact plate 5 is arranged at the top of the horizontal shock absorbing mechanism 4; shock absorber heat dissipation mechanisms 6 are arranged on both sides of the shock absorbing box body 1.

[0028] The shield machine contact plate 5 is located at the top of the horizontal vibration reduction mechanism 4 and is directly connected to the main body or other key components of the shield machine. The shield machine contact plate 5 is intended to transmit the vibration reduction effect to the shield machine and reduce the impact of vibration on the whole machine.

[0029] With the help of the above scheme, the utility model can reduce the vibration generated by the shield machine during the excavation process, while taking into account the dual needs of vibration and thermal management, improving the heat dissipation efficiency, and can significantly improve the stability of the shield machine and extend the service life of the equipment.

[0030] In one embodiment, for the vertical damping mechanism 2, the vertical damping mechanism 2 includes a plurality of first dampers 201 arranged in the damping box 1, a support plate 202 is arranged at the top of the first damper 201, and a receiving box 3 is arranged at the top of the support plate 202; a plurality of guide rods 203 are arranged on the inner wall of the damping box 1, and grooves 204 matching the guide rods 203 are arranged on both sides of the support plate 202, so as to effectively absorb and alleviate the vertical vibration caused by the unevenness of the ground or the change of rock and soil mechanics when the shield machine is working, and ensure the continuity and reliability of the damping effect. In addition, the cooperation between the groove 204 and the guide rod 203 makes the vertical damping mechanism 2 more stable during vertical movement, reducing possible swing or deviation.

[0031] In one embodiment, for the above-mentioned horizontal shock absorbing mechanism 4, the horizontal shock absorbing mechanism 4 includes a square block 401 arranged inside the containing box 3, and a plurality of second shock absorbers 402 are arranged between the side wall of the square block 401 and the inner wall of the containing box 3; a plurality of first fans 403 are arranged below the second shock absorbers 402 and located inside the containing box 3, and the air outlet of the first fan 403 faces upward, wherein a plurality of blind holes 7 are arranged inside the square block 401, and a support rod 8 is arranged in the blind hole 7, and the top of the support rod 8 is connected to the shield machine contact plate 5, so as to effectively absorb and isolate horizontal vibrations, and the first fan 403 helps to effectively dissipate the heat caused by the second shock absorber 402 during the shock absorption process.

[0032] The working principle of the vertical shock absorbing mechanism 2 and the horizontal shock absorbing mechanism 4 is as follows: the first shock absorber 201 is used to absorb the direct impact from the underground vibration during the operation of the shield machine, and the support plate 202 cooperates with the guide rod 203 through the groove 204 to ensure smoother and more stable movement in the vertical direction and reduce the vibration and displacement caused by uneven ground. The second shock absorber 402 is responsible for absorbing the vibration in the horizontal direction, and the first fan 403 is installed below the second shock absorber 402 to help dissipate the heat generated by the second shock absorber 402 due to vibration damping.

[0033] In addition, the first shock absorber 201 and the second shock absorber 402 are made of spring, hydraulic or rubber materials. In heavy machinery such as shield machines, the use of shock absorbers can effectively reduce vibrations during operation. During operation, the shield machine will encounter vibrations along the tunnel axis (horizontally) as well as vertical vibrations caused by uneven soil pressure underground or operating errors. Setting shock absorption in both horizontal and vertical directions can more comprehensively reduce the impact of these vibrations on the machine.

[0034] In one embodiment, for the above-mentioned shock absorber heat dissipation mechanism 6, the shock absorber heat dissipation mechanism 6 includes a mounting plate 601 arranged on one side of the shock absorber box 1, the mounting plate 601 is connected to the shock absorber box 1 by bolts 602, a plurality of second fans 603 are arranged on the side wall of the mounting plate 601, and a plurality of heat dissipation holes 604 are arranged on the other side of the shock absorber box 1, so as to actively cool the heat generated by the first shock absorber 201, effectively reducing the temperature of the first shock absorber 201 under a high-load working environment, and the heat dissipation holes 604 promote air circulation and ensure the heat dissipation effect.

[0035] The working principle of the shock absorber heat dissipation mechanism 6 is as follows: the second fan 603 is responsible for actively cooling the first shock absorber 201. The heat dissipation holes 604 are arranged on the other side of the shock absorber housing 1 to promote air circulation and enhance the overall heat dissipation effect.

[0036] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0037] In actual application, the vertical damping mechanism 2 and the horizontal damping mechanism 4 are combined to effectively control and alleviate the multi-directional vibration generated by the shield machine when working under complex geological conditions. The setting of the damper heat dissipation mechanism 6 ensures that the temperature of the vertical damping mechanism 2 is effectively controlled during long-term operation to avoid overheating affecting the damping effect.

[0038] In summary, the utility model can reduce the vibration generated by the shield machine during the excavation process, while taking into account the dual needs of vibration and thermal management, improving the heat dissipation efficiency, and significantly improving the stability of the shield machine and extending the service life of the equipment. By setting a vertical shock-absorbing mechanism 2 and a horizontal shock-absorbing mechanism 4, the vertical vibration caused by the unevenness of the ground or the change of rock and soil mechanics when the shield machine is working can be effectively absorbed and alleviated, thereby ensuring the continuity and reliability of the shock-absorbing effect, and effectively absorbing and isolating the horizontal vibration. The first fan 403 helps to effectively dissipate the heat caused by the second shock absorber 402 during the shock absorption process. By setting a shock absorber heat dissipation mechanism 6, the heat generated by the first shock absorber 201 is actively cooled, effectively reducing the temperature of the first shock absorber 201 under a high-load working environment, and the heat dissipation hole 604 promotes air circulation and ensures the heat dissipation effect.
