Description

Technical Field

[0001] This utility model relates to the technical field of concrete pipe bases, specifically a robust and durable anti-settlement device for concrete pipe bases. Background Technology

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. They can be divided into four types: plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes. Based on the inner diameter, they can be divided into small-diameter pipes (below 400 mm), medium-diameter pipes (400–1400 mm), and large-diameter pipes (above 1400 mm). Based on the water pressure resistance, they can be divided into low-pressure pipes and pressure pipes. Pressure pipes typically have working pressures of 0.4, 0.6, 0.8, 1.0, and 1.2 MPa. Compared to steel pipes, concrete pipes can also be divided into plain-end pipes, socket-end pipes, and tongue-and-groove pipes based on the type of joint. Joint types include cement mortar joints, wire mesh cement mortar joints, cement mortar sockets, and rubber ring sockets.

[0003] Currently available concrete pipe bases cannot fit snugly against the inner wall of the tunnel during use, causing the concrete pipes to sink. Furthermore, the lack of fixing devices during the installation of concrete pipes makes it impossible to quickly align two concrete pipes. Therefore, there is an urgent need for a robust and durable concrete pipe base anti-settlement device to improve these problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a robust and durable anti-settlement device for concrete pipe bases to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a robust and durable anti-settlement device for a concrete pipe base, comprising a concrete pipe, a support device at the bottom of the concrete pipe, the support device including a fixing frame, an installation hole inside the fixing frame, a bidirectional threaded rod inside the installation hole, internal hexagonal holes at both ends of the bidirectional threaded rod, an mounting bracket A outside the bidirectional threaded rod, a threaded hole inside the mounting bracket A, a support rod inside the mounting bracket A, a mounting bracket B at one end of the support rod, a baffle on one side of the mounting bracket B, and a positioning cone on one side of the baffle.

[0007] The present invention is further configured such that: the bidirectional threaded rod is rotatably connected to the inside of the mounting hole, the threaded hole is adapted to the bidirectional threaded rod, and the mounting bracket A and mounting bracket B are respectively rotatably connected to the two ends of the support rod.

[0008] By adopting the above technical solution, mounting bracket A and mounting bracket B are rotatably connected to both ends of the support rod, which facilitates the rotation of the support rod.

[0009] The present invention is further configured such that: the mounting bracket B is fixedly connected to one side of the baffle, and the positioning cone is fixedly connected to the other side of the baffle.

[0010] By adopting the above technical solution, the mounting bracket B is fixedly connected to one side of the baffle, and plays a role in transmission.

[0011] The present invention is further configured such that: a fixing device is provided on the top of the fixing frame, the fixing device includes a support frame and a mounting block, an installation groove is provided inside the mounting block, a spring rod is provided inside the installation groove, a clamping plate is provided at one end of the spring rod, a frame is provided on one side of the plate, a triangular plate is provided at the bottom of the frame, and a fixing plate is provided at the top of the frame.

[0012] By adopting the above technical solution, a triangular plate is set at the bottom of the frame to push the card plate to slide.

[0013] The present invention is further configured such that: the support frame and the mounting block are both fixedly connected to the top of the fixing frame, one end of the spring rod is fixedly connected to the inside of the mounting groove, and the other end of the spring rod is fixedly connected to the card plate.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] 1. This robust and durable concrete pipe base anti-settlement device features an internal mounting hole in the fixing frame to facilitate the rotation of the bidirectional threaded rod. An internal hexagonal hole in the bidirectional threaded rod facilitates its rotation. The combination of the bidirectional threaded rod and the threaded hole allows the mounting frame A to slide within the fixing frame. The cooperation of fixing frame A, the support rod, and fixing frame B pushes the baffle and positioning cone to fit against the inner wall of the tunnel. Using this structure, when the fixing frame is installed on the ground, its two sides can fit against the inner wall of the tunnel, effectively preventing the concrete pipe from settling.

Example

[0029] Reference Figure 1 , Figure 2 and Figure 3 This utility model discloses a robust and durable anti-settlement device for a concrete pipe base, comprising a concrete pipe 1, a support device 2 at the bottom of the concrete pipe 1, a fixing frame 3, an installation hole 4 inside the fixing frame 3, a bidirectional threaded rod 5 inside the installation hole 4, and internal hexagonal holes 6 at both ends of the bidirectional threaded rod 5. An installation bracket A7 is provided on the outside of the bidirectional threaded rod 5, with threaded holes 8 inside the installation bracket A7 and a support rod 9 inside the installation bracket A7. An installation bracket B10 is provided at one end of the support rod 9, a baffle 11 is provided on one side of the installation bracket B10, and a positioning cone 12 is provided on one side of the baffle 11. In this embodiment, the fixing frame 3 serves to contact the ground, the installation hole 4 facilitates the rotation of the bidirectional threaded rod 5, and the internal hexagonal holes 6 facilitate the rotation of the bidirectional threaded rod 5.

[0030] Reference Figure 2 and Figure 3 The bidirectional threaded rod 5 is rotatably connected to the inside of the mounting hole 4. The threaded hole 8 is adapted to the bidirectional threaded rod 5. The mounting bracket A7 and the mounting bracket B10 are rotatably connected to the two ends of the support rod 9, respectively. In this embodiment, the bidirectional threaded rod 5 plays a transmission role, the mounting bracket A7 drives the support rod 9 to rotate, and the mounting bracket B10 facilitates the rotation of the support rod 9.

[0031] Reference Figure 2 and Figure 3The mounting bracket B10 is fixedly connected to one side of the baffle 11, and the positioning cone 12 is fixedly connected to the other side of the baffle 11. In this embodiment, the baffle 11 serves to fit against the inner wall of the tunnel, and the positioning cone 12 serves to limit the movement.

[0032] Reference Figure 4 and Figure 5 The top of the fixing frame 3 is provided with a fixing device 13. The fixing device 13 includes a support frame 14 and a mounting block 15. The mounting block 15 has a mounting groove 16 inside. A spring rod 17 is provided inside the mounting groove 16. A clamping plate 18 is provided at one end of the spring rod 17. A frame 19 is provided on one side of the plate. A triangular plate 20 is provided at the bottom of the frame 19. A fixing plate 21 is provided at the top of the frame 19. In this embodiment, the support frame 14 plays a limiting role, and the mounting block 15 plays a mounting structure role.

[0033] Reference Figure 4 and Figure 5 The support frame 14 and the mounting block 15 are both fixedly connected to the top of the fixed frame 3. One end of the spring rod 17 is fixedly connected to the inside of the mounting groove 16, and the other end of the spring rod 17 is fixedly connected to the clamping plate 18. In this embodiment, the mounting groove 16 serves to install the spring 17 and facilitates the sliding of the clamping plate 18. The spring rod 17 serves to drive the clamping plate 18 to reset.

[0034] Reference Figure 4 and Figure 5 The card plate 18 is slidably connected to the inside of the mounting groove 16, the triangular plate 20 is fixedly connected to the bottom of the frame 19, and the fixing plate 21 is fixedly connected to the top of the frame 19. In this embodiment, the frame 19 plays a limiting role, the fixing plate 21 plays a role in clamping the concrete pipe 1, and the triangular plate 20 plays a role in pushing the card plate 18 to slide.

[0035] The implementation principle of this embodiment is as follows:

[0036] In actual use, the fixing frame 3 needs to be placed inside the tunnel first. Then, the staff uses a tool to clamp it into the inside of the internal hexagonal hole 6. The internal hexagonal hole 6 drives the double-threaded rod 5 to rotate inside the mounting hole 4. During the rotation of the double-threaded rod 5, the threaded engagement between the double-threaded rod 5 and the threaded hole 8 will drive the mounting frame A7 to slide inside the fixing frame 3. As the double-threaded rod 5 continues to rotate, the distance between the two mounting frames A7 gradually increases. At the same time, the angle between the support rod 9 and the double-threaded rod 5 also gradually increases. The baffle 11 will gradually approach the inner wall of the tunnel until the baffle 11 is in contact with the inner wall of the tunnel. At this time, the positioning cone 12 will also be clamped in the inner wall of the tunnel. At this time, except that the bottom of the fixing frame 3 is in contact with the empty tunnel, the fixing frame 3 can be installed into the inside of the tunnel through the support rod 9, which increases the usable area of ​​the fixing frame 3 and thus prevents the concrete pipe 1 from sinking.

[0037] During the process of the bidirectional threaded rod 5 driving the mounting bracket A7 to move, the angle of the support rod 9 will change. Its two ends rotate inside the mounting bracket A7 and the mounting bracket B10 respectively, which can change the distance between the baffles 11 to adapt to the tunnels of different widths, and can connect the baffles 11 and the fixing bracket 3 to enhance the stability of the fixing bracket 3.

[0038] After the fixing frame 3 is installed inside the tunnel, the concrete pipe 1 is transported to the top of the support frame 14 using lifting equipment. When the concrete pipe 1 moves to the top of the support frame 14, the concrete pipe 1 is slowly moved downwards until it is locked inside the support frame 14. During this process, workers need to push the concrete pipe 1 to assist in positioning. When the concrete pipe 1 moves to the appropriate position, the fixing plate 21 is installed on top of the concrete pipe 1. As the concrete pipe 1 continues to move downwards, the triangular plate 20 will contact the locking plate 18. As the triangular plate 20 continues to move downwards, it will push the locking plate 18 to slide inside the mounting groove 16. At the same time, the output shaft of the spring rod 17 will be compressed until the triangular plate 20 drives the frame 19 to lock inside the mounting groove 16. Then, the output shaft of the spring rod 17 will pop out and push the locking plate 18 to reset, locking the frame 19 and the triangular plate 20 inside the mounting groove 16. At this time, the installation of the fixing plate 21 is completed, and the fixing plate 21 wraps around the outside of the concrete pipe 1, firmly installing the pipe body on the top of the support frame 14.

[0039] Compared with the prior art, the present invention has the following advantages:

[0040] The mounting hole 4 inside the fixing frame 3 facilitates the rotation of the bidirectional threaded rod 5. The internal hexagonal hole 6 inside the bidirectional threaded rod 5 facilitates its rotation. The cooperation between the bidirectional threaded rod 5 and the threaded hole 8 allows the mounting frame A7 to slide within the fixing frame 3. The cooperation between the fixing frame 3A, the support rod 9, and the fixing frame 3B pushes the baffle 11 and the positioning cone 12 to fit against the inner wall of the tunnel. Using this structure, when the fixing frame 3 is installed on the ground, its two sides can fit against the inner wall of the tunnel, effectively preventing the concrete pipe 1 from sinking. The addition of support frame 14 facilitates the placement of concrete pipe 1. The installation groove 16 inside the mounting block 15 facilitates the installation of spring rod 17 and clamping plate 18. The installation of triangular plate 20 at the bottom of frame 19 facilitates the sliding of clamping plate 18 inside the installation groove 16. The cooperation between frame 19 and fixing plate 21 fixes concrete pipe 1. The addition of spring rod 17 pushes clamping plate 18 to reset. By using the above structure, after placing concrete pipe 1 on top of support frame 14, it can be fixed to facilitate the splicing of two concrete pipes 1.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
