Description

Technical Field

[0001] This invention relates to the field of prestressed steel cylinder concrete pipe production and construction technology, and in particular to a prestressed steel cylinder concrete pipe turning device. Background Technology

[0002] Prestressed concrete cylinder pipe refers to a water pipe made by winding circumferential prestressed steel wires around a high-strength concrete core with a steel cylinder, and then spraying a dense cement mortar protective layer on top. It is a composite pipe composed of thin steel plates, high-strength steel wires, and concrete, which fully and comprehensively utilizes the tensile strength and sealing properties of steel and the compressive strength and corrosion resistance of concrete, resulting in high sealing performance, high strength, and high impermeability.

[0003] Prestressed concrete cylinder pipes are typically installed vertically after production. During transportation and installation, they need to be laid flat. However, due to their large size and weight, turning them over requires specialized equipment and skilled operators. Currently, a crane is mainly used to lift the pipes from the top and gradually lower them. This method is not only inefficient, but improper operation or equipment failure can also lead to collisions between the pipes and the ground, other objects, or equipment, causing damage to the outer wall of the pipe or the inner steel cylinder lining. Furthermore, prestressed concrete cylinder pipes have a certain rigidity and weight; uneven stress or exceeding their load-bearing capacity during turning can cause structural deformation, such as bulges or dents, affecting the pipe's performance. Additionally, inadequate safety measures or operator negligence during the turning process can lead to accidents such as pipe falls and injuries.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] Reference Figures 1-4 The present invention provides a prestressed steel cylinder concrete pipe overturning device, comprising:

[0033] Base 1, with a base platform 2 fixedly connected to one side of the top of base 1;

[0034] The clamping assembly includes a support frame 3 and two clamping members. The support frame 3 is mounted on the base 2, and the two clamping members are respectively mounted at both ends of the support frame 3. The two clamping members are used to clamp both ends of the steel cylinder concrete pipe 4.

[0035] The flipping assembly includes a rotating base 5, a flipping component, and a connecting component. A flipping groove is provided on the base 2. The flipping component is rotatably connected in the flipping groove. The rotating base 5 rotates in the flipping groove through the flipping component. One end of the support frame 3 is fixedly connected to the top of the rotating base 5. A support rod 6 is fixedly connected to the base 1. The connecting component is set at the top of the support rod 6 and connected to the other end of the support frame 3.

[0036] The buffer assembly includes a first buffer and a second buffer. The first buffer is mounted on the rotating base 5 and connected to the base 2, and the second buffer is mounted on the base 1 and contacts the steel cylinder concrete pipe 4.

[0037] The scheme is further optimized by providing several first sliding grooves 7 at equal intervals along the circumference at both ends of the support frame 3. The clamping component includes a first slider 8 slidably connected in the first sliding groove 7. A second sliding groove 9 is provided on the first slider 8. Two clamping plates 10 are slidably connected in the second sliding groove 9. The two clamping plates 10 are in contact with the outer and inner side walls of the steel cylinder concrete pipe 4, respectively. Both ends of the support frame 3 are provided with driving components. The first slider 8 and the two clamping plates 10 are respectively connected to the driving components for transmission.

[0038] Reference Figure 2 The position of the clamping plate 10 is adjusted by sliding the first slider 8 in the first slide groove 7 to match the steel cylinder concrete pipe 4 of the corresponding size. After adjustment, the clamping plate 10 is adjusted to slide in the second slide groove 9 to achieve clamping of the steel cylinder concrete pipe 4 wall by the two clamping plates 10.

[0039] Specifically, the clamping plate 10 can be configured as a telescopic structure, that is, to ensure that the two clamping plates 10 can be placed on the outer wall and inner wall of the steel cylinder concrete pipe 4 respectively. The specific telescopic plate is existing technology, and it is sufficient to have telescopic function, which will not be described in detail here.

[0040] The scheme is further optimized. The driving component includes a threaded rod 11 rotatably connected in the first slide groove 7 and a bidirectional threaded rod 12 rotatably connected in the second slide groove 9. The first slider 8 is threadedly connected to the threaded rod 11. The two clamping plates 10 are respectively threadedly connected to both ends of the bidirectional threaded rod 12. The support frame 3 has cavities inside both ends. One end of the bidirectional threaded rod 12 is fixedly connected to one end of the telescopic rod 13. The other end of the telescopic rod 13 and one end of the threaded rod 11 both extend into the cavity and are fixedly connected to the first bevel gear 14. Two motors 15 are fixedly connected in the cavity. The output shafts of the two motors 15 are fixedly connected to the second bevel gears 16. The first bevel gear 14 on the telescopic rod 13 and the first bevel gear 14 on the threaded rod 11 mesh with the two second bevel gears 16 respectively.

[0041] Reference Figure 2The motor 15 drives the second bevel gear 16 to rotate, which in turn drives the first bevel gear 14 to rotate. When the first bevel gear 14 rotates, it drives the corresponding threaded rod 11 to rotate, thereby adjusting the position of the first slider 8. When the corresponding telescopic rod 13 rotates, it drives the bidirectional threaded rod 12 to rotate, thereby adjusting the position of the two clamping plates 10.

[0042] Specifically, the telescopic rod 13 consists of two connected square tubes. One square tube is fixedly connected to the bidirectional threaded rod 12, while the other square tube rotates on the inner wall of the cavity and is fixedly connected to the first bevel gear 14. This ensures that the rod has the function of length adjustment while also ensuring that it rotates synchronously with the second bevel gear 16.

[0043] The scheme is further optimized. A groove 17 is provided in the flipping slot. The flipping component includes a rotating shaft 18 rotatably connected in the groove 17. A first gear 19 is fixedly connected to the rotating shaft 18. A first toothed plate 20 is fixedly connected to the bottom of the rotating base 5. The first toothed plate 20 is located in the groove 17 and meshes with the first gear 19. A control component is provided in the base 2. The rotating shaft 18 is connected to the control component in a transmission connection.

[0044] Reference Figure 2 The first gear 19 meshes with the first toothed plate 20. When the first gear 19 rotates, it drives the rotating base 5 to rotate in the tilting groove through the meshing first toothed plate 20, thereby causing the steel cylinder concrete pipe 4 to tilt.

[0045] The scheme is further optimized. The control components include first hydraulic cylinders 21 fixedly connected to both ends inside the base 2. The telescopic ends of the two first hydraulic cylinders 21 are fixedly connected to second gear plates 22. The two ends of the rotating shaft 18 extend into the base 2 and are fixedly connected to second gears 23. The second gears 23 mesh with the second gear plates 22.

[0046] Reference Figure 3 The first hydraulic cylinder 21 drives the second gear plate 22 to move. When the second gear plate 22 moves, it drives the meshing second gear 23 to rotate, thereby driving the first gear 19 to rotate through the second gear 23, thus realizing the control of the first gear 19.

[0047] The scheme is further optimized. The connecting component includes a winding box 24 fixedly connected to the top of the support rod 6. A winding roller 25 is provided inside the winding box 24. One end of a steel wire rope 26 is fixedly connected to the winding roller 25. The other end of the steel wire rope 26 extends out of the winding box 24 and is fixedly connected to the top of the support frame 3.

[0048] Reference Figure 1 , Figure 4 The steel wire rope 26 is connected to the support frame 3. During the rotation of the steel cylinder concrete pipe 4, the stability of the rotation process is ensured by the connection of the steel wire rope 26.

[0049] The scheme is further optimized. Guide grooves 27 are provided on both sides of the rotating base 5. The first buffer includes a spring 28 with one end fixedly connected to the inner wall of the guide groove 27. A cylinder 29 is fixedly connected to both sides of the flip groove. The cylinder 29 extends into the guide groove 27 and is fixedly connected to the other end of the spring 28.

[0050] Reference Figure 2 The guide groove 27 is an arc-shaped guide groove, and its shape is adapted to the flipping trajectory of the rotating base 5. When the rotating base 5 rotates, the spring 28 is squeezed between the inner wall of the guide groove 27 and the cylinder 29. The spring 28 plays a partial buffering role, thereby ensuring the stability of the flipped steel cylinder concrete pipe 4.

[0051] In a further optimized design, the second buffer component includes a second hydraulic cylinder 30 hinged to the top of the base 1. The telescopic end of the second hydraulic cylinder 30 is hinged to a buffer plate 31, which contacts the outer wall of the steel cylinder concrete pipe 4.

[0052] Reference Figure 1 The second hydraulic cylinder 30 drives the buffer plate 31 to contact the steel cylinder concrete pipe 4, further supporting the steel cylinder concrete pipe 4 during the flipping process and ensuring its stable flipping.

[0053] The design is further optimized so that two support columns 32 are fixedly connected to the top of the base 1, and a support plate 33 is fixedly connected to the top of the support column 32. The support plate 33 is used to support the steel cylinder concrete pipe 4.

[0054] Reference Figure 1 The support plate 33 is used to support the overturned steel cylinder concrete pipe 4. At the same time, it has an arc-shaped structure that matches the shape of the outer wall of the steel cylinder concrete pipe 4, and its height matches the height of the overturned steel cylinder concrete pipe 4.

[0055] The design was further optimized so that the cross-section of the tilting groove is a semi-circular structure.

[0056] Reference Figure 2 The flipping groove has a semi-circular structure, and the corresponding rotating base 5 is also a semi-circular structure that is adapted to the flipping groove. The rotating base 5 flips 90 degrees in the flipping groove to flip the steel cylinder concrete pipe 4 from a vertical state to a horizontal state.

[0057] Example 2:

[0058] Reference Figure 5 The support frame 3 and the rotating base 5 are separate structures. The top of the rotating base 5 is equipped with a scissor telescopic device, which drives the support frame 3 away from the rotating base 5.

[0059] The scheme is further optimized by installing several moving rollers on the inner wall of the pallet 33. The moving rollers contact the steel cylinder concrete pipe 4. When the steel cylinder concrete pipe 4 is placed horizontally, the scissor telescopic device drives the steel cylinder concrete pipe 4 to move on the moving rollers. At the same time, a transport vehicle is parked on one side of the device. The scissor telescopic device pushes the steel cylinder concrete pipe 4 into the transport vehicle. After loading is completed, the support frame 3 is removed from the steel cylinder concrete pipe 4, and the steel cylinder concrete pipe 4 is transported to the construction site by the transport vehicle.

[0060] In one embodiment of the present invention, the specific number and height of the pallets 33, as well as the overall horizontal conveying height of the device, are adapted to the transport vehicle.

[0061] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0062] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
