[0031] With the acceleration of urbanization, subway construction has become an important means of alleviating urban traffic pressure. During subway tunnel construction, the shield tunneling method is widely used in underwater tunnel construction due to its advantages such as safety, efficiency, and environmental friendliness. However, various obstacles, such as underwater obstacle piles, are often encountered during underwater shield tunneling.

[0032] Currently, the removal of underwater obstacle piles in subway shield tunnels mainly employs mechanical breaking methods. This method typically uses large equipment such as hydraulic breakers and drilling rigs, which are mounted on an underwater work platform for operation. The breaking equipment is positioned using a robotic arm or guiding system to ensure accurate alignment with the obstacle pile for breaking operations.

[0033] However, due to the large size and heavy weight of these devices, moving and positioning them in the underwater environment is extremely difficult. This makes it difficult for operators to accurately control the movement and positioning of the devices, which seriously affects the accuracy and efficiency of the demolition operation, not only prolonging the construction period but also increasing the construction cost.

[0034] To solve the technical problem, the utility model provides a subway shield tunnel obstacle pile breaking device.

[0035] Please refer to Figures 1 to 3 In an embodiment of the utility model, the subway shield tunnel obstacle pile is arranged in water; the subway shield tunnel obstacle pile breaking device comprises a support 100, an obstacle pile breaking mechanism 200 and a position adjusting mechanism 300; the obstacle pile breaking mechanism 200 is detachably arranged along the vertical direction around the subway shield tunnel obstacle pile, the obstacle pile breaking mechanism 200 and the position adjusting mechanism 300 are installed along the vertical direction and are spaced apart on the support 100, and the position adjusting mechanism 300 is arranged above the obstacle pile breaking mechanism 200; wherein the position adjusting mechanism 300 is provided with a fluid filling cavity 301, and the fluid filling cavity 301 is used for filling fluid and generating buoyancy in water.

[0036] Specifically, the obstacle pile breaking mechanism 200 can adopt a hydraulic breaking hammer, a drilling machine or other suitable breaking tools. The obstacle pile breaking mechanism 200 can be detached along the vertical direction, which facilitates installation and detachment on obstacle piles of different heights, and improves the applicability of the subway shield tunnel obstacle pile breaking device. The obstacle pile breaking mechanism 200 is fixed through the support 100, which ensures stability during breaking.

[0037] The position adjusting mechanism 300 is arranged above the obstacle pile breaking mechanism 200, which is conducive to adjusting the center of gravity of the entire subway shield tunnel obstacle pile breaking device and improving the flexibility of underwater operation. The position adjusting mechanism 300 is provided with a fluid filling cavity 301, which is used for filling fluid and generating buoyancy in water. The fluid filling cavity 301 can be one or more sealed cavities, and fluid can be filled and discharged through a fluid filling pipe 322.

[0038] In actual application, when it is necessary to adjust the position of the subway shield tunnel obstacle pile breaking device, fluid (such as compressed air or other low-density fluid) can be filled into the fluid filling cavity 301. After the fluid is filled, the fluid filling cavity 301 generates upward buoyancy in water, and this buoyancy can effectively reduce the control weight of the support 100 and the obstacle pile breaking mechanism 200. The control weight refers to the weight value of the self-weight of the subway shield tunnel obstacle pile breaking device minus the buoyancy.

[0039] In addition, by adjusting the amount of fluid in the fluid filling cavity 301, the size of the buoyancy of the subway shield tunnel obstacle pile breaking device can be accurately controlled. When it is necessary to move the device upward, the amount of fluid filling is increased to generate greater buoyancy; when it is necessary to move downward, the amount of fluid filling is reduced to reduce the buoyancy. The required force for adjusting the position of the subway shield tunnel obstacle pile breaking device can be significantly reduced, so that the operator can more easily perform accurate positioning.

[0040] In an alternative embodiment, the fluid filling cavity 301 can be multiple independent chambers, each of which can control the filling and discharge of fluid independently. The operator can adjust the attitude of the device more finely, not only controlling the overall up and down movement, but also adjusting the inclination angle of the device to adapt to different shapes and positions of the obstacle pile.

[0041] In another alternative embodiment, the fluid filling cavity 301 can be connected to an external water pump system, and the water pump can be used to control the inflow and outflow of water to achieve rapid buoyancy adjustment. It is suitable for situations that require frequent position adjustment, which can significantly improve work efficiency.

[0042] In addition, the position adjustment mechanism 300 can also be equipped with a pressure sensor and a water depth sensor to monitor the internal pressure of the fluid filling cavity 301 and the water depth of the device in real time. These data can be transmitted to the control system to assist the operator in calculating the required buoyancy, thereby achieving more accurate position adjustment.

[0043] In the technical scheme provided by the utility model, the fluid filling cavity 301 is arranged in the position adjustment mechanism 300 of the subway shield tunnel obstacle pile breaking device, and the controllable buoyancy generated by the fluid filling cavity 301 effectively reduces the control weight of the subway shield tunnel obstacle pile breaking device in water. The position adjustment of the subway shield tunnel obstacle pile breaking device becomes easier and more accurate, improving the accuracy and efficiency of underwater obstacle pile breaking operation. The operator can more accurately control the position and attitude of the device to ensure that the subway shield tunnel obstacle pile breaking device accurately aligns with the underwater obstacle pile. Moreover, since the position adjustment is more rapid and accurate, unnecessary subway shield tunnel obstacle pile breaking device attitude adjustment time is reduced, and the construction period is shortened.

[0044] Please continue to refer to Figures 1 to 3 In the embodiment of the utility model, the support 100 includes a support ring 110 and a limiting pipe 120, the limiting pipe 120 extends vertically, the support ring 110 is sleeved at the bottom end of the limiting pipe 120, and the obstacle pile breaking mechanism 200 and the position adjustment mechanism 300 are installed vertically and spaced apart on the support ring 110.

[0045] Specifically, the limiting pipe 120 extends vertically, providing vertical guidance and support for the entire subway shield tunnel obstacle pile breaking device. The support ring 110 is sleeved at the bottom end of the limiting pipe 120, forming the base platform of the device. The obstacle pile breaking mechanism 200 and the position adjustment mechanism 300 are installed vertically and spaced apart on the support ring 110, optimizing the center of gravity distribution of the device and improving the overall stability.

[0046] More specifically, the position adjusting mechanism 300 is arranged above the obstacle pile breaking mechanism 200, and the position adjusting mechanism 300 is provided with a fluid filling cavity 301. The support ring 110 provides a stable mounting base for the obstacle pile breaking mechanism 200, and the limiting tube 120 provides reliable support and protection for the position adjusting mechanism 300 and the fluid filling cavity 301 thereof. The vertical extension of the limiting tube 120 also facilitates the filling and emptying operation of the fluid filling cavity 301, for example, a fluid pipe can be arranged inside the limiting tube 120.

[0047] Please continue to refer to Figure 2 In the embodiment of the utility model, the position adjusting mechanism 300 includes a mounting ring 310 and a fluid filling structure 320, the mounting ring 310 is installed at the top of the support ring 110, and the fluid filling structure 320 is covered on the mounting ring 310, and the fluid filling structure 320 is provided with a fluid filling cavity 301, and the fluid filling cavity 301 is communicated with an external fluid filling mechanism.

[0048] Specifically, the mounting ring 310 is installed at the top of the support ring 110, which provides a stable base for the fluid filling structure 320. The fluid filling structure 320 is covered on the mounting ring 310, which ensures that the fluid filling cavity 301 can be evenly distributed around the device, which is conducive to maintaining the balance of the device in water. The fluid filling cavity 301 is communicated with the external fluid filling mechanism, so that the operator can conveniently control the filling and discharge of the fluid.

[0049] More specifically, the position adjusting mechanism 300 is arranged above the obstacle pile breaking mechanism 200. The mounting ring 310 not only provides support for the fluid filling structure 320, but also serves as a connection between the obstacle pile breaking mechanism 200 and the position adjusting mechanism 300. The fluid filling cavity 301 realizes precise adjustment of buoyancy through communication with the external fluid filling mechanism.

[0050] In an alternative embodiment, the fluid filling structure 320 can be made of flexible materials such as high-strength rubber or polyurethane to adapt to changes in water pressure and provide good sealing. The mounting ring 310 can be made of lightweight but high-strength materials such as aluminum alloy or titanium alloy to reduce the weight of the entire device. The operator can fill or discharge fluid into the fluid filling cavity 301 through the external fluid filling mechanism according to actual needs. When the device needs to be lifted, the amount of fluid filling is increased to generate greater buoyancy; when it needs to be lowered, the amount of fluid filling is reduced to reduce the buoyancy. This allows the operator to accurately control the position and attitude of the device, improving the efficiency and accuracy of underwater operations.

[0051] Please continue to refer to Figure 2In the embodiment of the utility model, the fluid filling structure 320 includes a fluid filling body 321 and a fluid filling pipe 322, the fluid filling body 321 is wrapped in the mounting ring 310, the fluid filling body 321 is provided with a fluid filling cavity 301, one end of the fluid filling pipe 322 is communicated with the fluid filling cavity 301, and the other end of the fluid filling pipe 322 is communicated with a fluid filling mechanism.

[0052] Specifically, the fluid filling body 321 is wrapped in the mounting ring 310, which ensures that the fluid filling cavity 301 can be uniformly distributed around the device, and is beneficial to maintaining the balance of the device in water. The fluid filling body 321 is provided with the fluid filling cavity 301, which provides space for the storage and adjustment of fluid. One end of the fluid filling pipe 322 is communicated with the fluid filling cavity 301, and the other end is communicated with the fluid filling mechanism, forming a complete fluid circulation path.

[0053] In an optional embodiment, the fluid filling pipe 322 can be made of pressure-resistant and corrosion-resistant materials, such as plastic, to ensure reliability in a high-pressure underwater environment.

[0054] Please continue to refer to Figure 2 In the embodiment of the utility model, the fluid filling pipe 322 extends into the limiting pipe 120 from the fluid filling body 321 and extends out of the top end of the limiting pipe 120 in the vertical direction.

[0055] Specifically, the fluid filling pipe 322 extends into the limiting pipe 120 from the fluid filling body 321, effectively protecting the fluid filling pipe 322 and reducing the influence of the external environment. The fluid filling pipe 322 extends out of the top end of the limiting pipe 120 in the vertical direction, so that the fluid filling pipe 322 can be directly communicated with the fluid filling mechanism above the water surface, facilitating the filling and discharge operation of the fluid by the operator. By arranging the fluid filling pipe 322 inside the limiting pipe 120, the influence of water flow on the fluid filling pipe 322 can be effectively reduced, and the stability of the entire system can be improved. At the same time, the external structure of the device is simplified, and the protruding part that may be hooked by the obstacle in water is reduced. The fluid filling pipe 322 extends out of the top end of the limiting pipe 120, so that the operator can directly operate the filling and discharge of the fluid above the water surface without complex underwater operation.

[0056] In actual application, the limiting pipe 120 can be provided with a limiting structure, such as a groove or a fixed ring, inside to ensure the stability of the fluid filling pipe 322 inside the limiting pipe 120. The part of the fluid filling pipe 322 extending out of the top end of the limiting pipe 120 can be provided with a quick connection joint, facilitating the quick connection and disassembly of the fluid filling mechanism.

[0057] Please continue to refer to Figure 2In the embodiment of the utility model, subway shield tunnel obstacle pile breaking device still includes a plurality of installation leg 330, a plurality of installation leg 330 is along the circumferential spacing of installation ring 310 is arranged, and one end of each installation leg 330 is connected with the bottom of installation ring 310, and the other end of each installation leg 330 is connected with the circumferential wall of support ring 110.

[0058] Specifically, installation ring 310 is connected with support ring 110 through a plurality of installation legs 330, which ensures the spatial independence between position adjusting mechanism 300 and obstacle pile breaking mechanism 200, so that position adjusting mechanism 300 can be stably installed on support ring 110 while maintaining a proper distance from obstacle pile breaking mechanism 200. When fluid-filled cavity 301 is filled with fluid to generate buoyancy, a plurality of installation legs 330 can evenly disperse the force, prevent local stress concentration, and ensure the stability of the entire device. In addition, a plurality of installation legs 330 are arranged along the circumference of installation ring 310, and the space between installation legs 330 can also be used to arrange other functional components or pipelines, improving the space utilization.

[0059] One end of installation leg 330 is connected with the bottom of installation ring 310, and the other end is connected with the circumferential wall of support ring 110, which not only can withstand vertical force, but also can effectively resist horizontal shear force and torsional force, thereby improving the stability of the entire device in underwater environment.

[0060] Please continue to read Figure 2 In the embodiment of the utility model, fluid filling structure 320 extends along the circumference of installation ring 310.

[0061] Specifically, fluid filling structure 320 extends along the circumference of installation ring 310, so that fluid-filled cavity 301 can be evenly distributed around the device. It can provide more balanced buoyancy distribution, which helps to maintain the stability of the device in water; and the circumferentially extending structure increases the total volume of fluid-filled cavity 301, thereby improving the range and accuracy of buoyancy adjustment, so that the device can have the same buoyancy in all directions, which is conducive to maintaining the balance of the device.

[0062] Please continue to read Figure 2 In the embodiment of the utility model, the number of fluid filling structure 320 is multiple, and a plurality of fluid filling structure 320 is arranged along the circumference of installation ring 310.

[0063] Specifically, the number of fluid filling structure 320 is multiple, which increases the buoyancy adjustment capacity and accuracy of the entire device. A plurality of fluid filling structure 320 is arranged along the circumference of installation ring 310, which ensures the uniformity and stability of buoyancy adjustment. The device can maintain balance in the horizontal direction, avoiding the inclination or instability caused by a single fluid filling structure 320.

[0064] More specifically, the position adjusting mechanism 300 is arranged above the obstacle pile breaking mechanism 200, and the position adjusting mechanism 300 is provided with a fluid filling cavity 301 for filling fluid and generating buoyancy in water. The arrangement of multiple fluid filling structures 320 further optimizes the performance of the position adjusting mechanism 300. Each fluid filling structure 320 can be independently controlled, which enables the operator to finely adjust the attitude and position of the device.

[0065] In practical applications, multiple fluid filling structures 320 can adopt the same structure, or different sizes or shapes according to needs. For example, larger fluid filling structures 320 can be arranged in the front, back, left and right directions of the device, while smaller fluid filling structures 320 can be arranged in other positions to achieve more flexible attitude control. Each fluid filling structure 320 can be equipped with an independent fluid filling pipe 322 and a control valve, so that the operator can control the buoyancy of each fluid filling structure 320 individually, and the operator can accurately adjust the attitude and position of the device according to actual needs. For example, when the device needs to be tilted forward, the buoyancy of the front fluid filling structure 320 can be increased, while the buoyancy of the rear fluid filling structure 320 can be reduced. When the device needs to be kept horizontal, the buoyancy of all fluid filling structures 320 can be adjusted uniformly. This operation mode not only improves the accuracy of adjustment, but also increases the adaptability of the device in complex underwater environments.

[0066] Please continue to refer to Figure 3 In the embodiment of the utility model, the obstacle pile breaking mechanism 200 includes a connecting ring 210, multiple connecting legs 220 and multiple obstacle pile breaking pieces 230, the connecting ring 210 is installed at the bottom of the supporting ring 110, the multiple connecting legs 220 are installed at the supporting ring 110 along the circumference of the connecting ring 210, and the number of the multiple connecting legs 220 and the multiple obstacle pile breaking pieces 230 is consistent and one-to-one correspondence.

[0067] It should be noted that the obstacle pile breaking piece 230 can select different breaking tools according to actual needs, such as hydraulic breaking hammer, drill bit or cutting tool.

[0068] Specifically, the connecting ring 210 is installed at the bottom of the supporting ring 110, which provides a stable foundation for the entire obstacle pile breaking mechanism 200. The multiple connecting legs 220 are installed at the supporting ring 110 along the circumference of the connecting ring 210, which ensures the stability and balance of the obstacle pile breaking mechanism 200. The number of the multiple connecting legs 220 and the multiple obstacle pile breaking pieces 230 is consistent and one-to-one correspondence, so that each obstacle pile breaking piece 230 can be effectively supported and controlled.

[0069] More specifically, the operator can adjust the configuration of the obstacle pile breaking mechanism 200 according to actual needs. For example, the appropriate number of connecting legs 220 and obstacle pile breaking pieces 230 can be selected according to the size and shape of the obstacle pile. When larger obstacle piles need to be broken, the number of connecting legs 220 and obstacle pile breaking pieces 230 can be increased; when smaller obstacle piles are processed, the number can be reduced to improve operational flexibility.

[0070] Through the cooperation of the connecting ring 210, the connecting leg 220 and the obstacle pile breaking piece 230, the obstacle pile is broken in all directions. The connecting ring 210 provides a stable support platform, the connecting leg 220 ensures the positioning accuracy of each obstacle pile breaking piece 230, and the obstacle pile breaking piece 230 directly performs the breaking operation. Not only improves the breaking efficiency of the underwater obstacle pile, but also ensures the safety and controllability of the breaking process.

[0071] Please continue to refer to Figure 3 In the embodiment of the utility model, one end of each connecting leg 220 is connected with the peripheral wall of the connecting ring 210, the other end of each connecting leg 220 is bent downward to form a connecting part 221, and each obstacle pile breaking piece 230 is installed on the corresponding connecting part 221.

[0072] Specifically, one end of the connecting leg 220 is connected with the peripheral wall of the connecting ring 210, ensuring the stability and carrying capacity of the entire obstacle pile breaking mechanism 200. The other end of the connecting leg 220 is bent downward to form a connecting part 221, so that the obstacle pile breaking piece 230 can contact the obstacle pile at an appropriate angle, not only increasing the structural strength, but also providing a suitable installation position and angle for the obstacle pile breaking piece 230, improving the breaking efficiency. Each obstacle pile breaking piece 230 is installed on the corresponding connecting part 221, so that the breaking force can be directly and effectively transmitted to the underwater obstacle pile.

[0073] More specifically, when the obstacle pile needs to be broken, each obstacle pile breaking piece 230 works simultaneously, and the breaking force is transmitted to the obstacle pile through the connecting part 221. The bending of the connecting leg 220 can also absorb part of the impact force, reducing the vibration effect on the entire device.

[0074] In actual application, the number and distribution of the connecting legs 220 can be adjusted according to the size and shape of the obstacle pile. For example, for larger obstacle piles, the number of connecting legs 220 can be increased to provide stronger breaking force; for irregularly shaped obstacle piles, the length and bending angle of the connecting leg 220 can be adjusted to ensure that each obstacle pile breaking piece 230 can effectively contact the surface of the obstacle pile.

[0075] The above merely illustrates the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the technical concept of the present application and by using the content of the present application specification and drawings are included in the patent protection scope of the present application.
