Description

Technical Field

[0001] This utility model relates to the field of PHC pipe pile core grouting technology, specifically a PHC pipe pile core grouting device. Background Technology

[0002] PHC pipe piles, or prestressed high-strength concrete pipe piles, are hollow cylindrical precast concrete components manufactured using a pre-tensioned prestressed centrifugal molding process and steam curing at approximately 10 atmospheres (around 1.0 MPa) and 180°C. The standard section length is 10m, with diameters ranging from 300mm to 800mm, and a concrete strength grade ≥C80. PHC pipe piles offer a high degree of mechanized construction, resulting in a clean and efficient construction environment, avoiding the mud-splattered mess of bored pile sites. This facilitates civilized construction, safe production, and reduces accidents, while also improving indirect economic benefits. Core grouting refers to the process of filling the pipe pile's interior with concrete using an internal core-filling method.

[0003] In existing technology, a filling pipe is inserted into the temporal part of the pipe pile and cement is injected into it. After it cools, the construction and stress conditions at the top of the pile can be improved, and it can also play a certain role in resisting shear. The length of the filling core is generally between 1 and 2 meters, which can both strengthen the pipe pile and save costs.

[0004] However, in actual use, due to the different diameters of the pipe openings of some PHC pipe piles, the grouting device may cause the grouting pipe to shake during grouting, thus reducing the grouting efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a PHC pipe pile core grouting device, which solves the problem that, in actual use, the grouting pipe shakes during grouting due to the varying diameters of the PHC pipe pile openings, thus reducing grouting efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PHC pipe pile core grouting device, comprising a connecting pipe, a pouring pipe fixedly connected to the bottom of the connecting pipe, a limiting shell sleeved on the lower outer wall of the pouring pipe, a protective shell sleeved on the upper outer wall of the pouring pipe, a clamping plate installed on the inner wall of the limiting shell, a sealing gasket fixedly connected to the top of the inner wall of the limiting shell, a connecting frame fixedly connected to the bottom of the protective shell, the bottom of the connecting frame fixedly connected to the top of the limiting shell, and an adjustment device installed on the outer wall of the clamping plate.

[0007] Preferably, the adjusting device includes a rectangular column, the outer wall of which is fixedly connected to the outer wall of the clamping plate, and a lead screw is threadedly connected to the inner wall of the rectangular column. The outer wall of the lead screw is rotatably connected to the inner wall of the limiting shell through a sealed bearing, and a handle is fixedly connected to one end of the lead screw that passes through the limiting shell.

[0008] Preferably, a fixing post is sleeved on the outer wall of the rectangular post, the outer wall of the fixing post is fixedly connected to the inner wall of the limiting shell, and a ball bearing is movably connected between the fixing post and the rectangular post.

[0009] Preferably, a servo motor is fixedly connected to the outer wall of the protective shell. The output end of the servo motor is fixedly connected to a drive rod through a sealed bearing at one end of the protective shell. A drive gear is fixedly connected to the outer wall of the drive rod. A driven gear is meshed with the outer wall of the drive gear. A fixed cylinder is fixedly connected to the inner wall of the driven gear. The inner wall of the fixed cylinder is rotatably connected to the inner wall of the protective shell through a bearing. A slider is threadedly connected to the inner wall of the fixed cylinder. The outer wall of the slider is fixedly connected to the outer wall of the irrigation pipe.

[0010] Preferably, a limiting post is inserted into the inner wall of the slider, and the outer wall of the limiting post is fixedly connected to the inner wall of the protective shell.

[0011] Beneficial effects

[0012] This utility model provides a PHC pipe pile core grouting device. It has the following advantages: Through the cooperation of a clamping plate, a limiting shell, and a pouring pipe, this PHC pipe pile core grouting device allows for stable pouring of concrete. The limiting shell is placed on top of the pipe pile, and the pouring pipe is inserted inside. The clamping plate then fixes the limiting shell to the outer wall of the pipe pile. This ensures stability during concrete pouring, preventing shaking and reducing pouring efficiency. It solves the problem that the pouring pipe in PHC pipe pile core grouting devices often shakes during pouring due to the varying diameters of the pipe openings, leading to reduced pouring efficiency.

[0013] By coordinating a servo motor, a drive rod, and a drive gear, when grouting pipe piles of different lengths, the servo motor drives the drive rod to rotate, and the meshing of the drive gear and the driven gear causes the fixed cylinder to rotate. The threaded connection between the fixed cylinder and the slider allows the length of the grouting pipe inserted into the pipe pile to be adjusted, thus solving the problem of inconvenience in grouting pipe piles of different lengths in existing technologies.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In actual use, because the diameter of the pipe opening of some PHC pipe piles is different, the grouting device will cause the grouting pipe to shake during the grouting process, which will reduce the grouting efficiency.

[0018] In view of this, the present invention provides a PHC pipe pile core grouting device, which solves the problem that in actual use, due to the different diameters of the pipe openings of some PHC pipe piles, the grouting pipe will shake during grouting, thus reducing the grouting efficiency.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Example 1: By Figure 1-4 It is known that a PHC pipe pile core grouting device includes a connecting pipe 1, a pouring pipe 2 fixedly connected to the bottom of the connecting pipe 1, a limiting shell 3 sleeved on the lower outer wall of the pouring pipe 2, a protective shell 4 sleeved on the upper outer wall of the pouring pipe 2, a clamping plate 9 installed on the inner wall of the limiting shell 3, a sealing gasket 8 fixedly connected to the top of the inner wall of the limiting shell 3, a connecting frame 15 fixedly connected to the bottom of the protective shell 4, the bottom of the connecting frame 15 fixedly connected to the top of the limiting shell 3, and an adjustment device installed on the outer wall of the clamping plate 9. In the specific implementation process, it is worth noting that the connecting pipe 1, as the main pipe, is connected to the feeding device at its top and to the pouring pipe 2 at the other end. The pouring pipe 2, as the main pipe inserted into the pipe pile, has a limiting shell 3 on its outer wall that ensures that the pouring pipe 2 is fixed stably inside the pipe pile. When the pouring pipe 2 is inserted into the pipe pile, the clamping plate 9 is clamped to the outer wall of the pipe pile by the adjusting device, so that the filling device is stable when working. The protective shell 4 on the top of the limiting shell 3 is protected by the connecting frame 15. The sealing gasket 8 is made of rubber, is annular, and has a large diameter. This seals the top of the pipe pile of different sizes with the limiting shell 3, preventing impurities from entering or leakage during the filling process. Furthermore, the adjustment device includes a rectangular column 10, the outer wall of which is fixedly connected to the outer wall of the clamping plate 9, and a screw rod 13 is threadedly connected to the inner wall of the rectangular column 10. The outer wall of the screw rod 13 is rotatably connected to the inner wall of the limiting shell 3 through a sealed bearing, and a handle 12 is fixedly connected to one end of the screw rod 13 that passes through the limiting shell 3. In the specific implementation process, it is worth noting that the inner wall of the rectangular column 10 is provided with the same internal thread as the outer wall of the screw rod 13. In this way, when the handle 12 drives the screw rod 13 to rotate, the clamping plate 9 is clamped on the outer wall of the pipe pile, so that the grouting pipe 2 is stable during filling. Two clamping plates 9 are provided, and each clamping plate 9 is set in a semi-circular shape. In this way, the force can be evenly distributed when clamping the pipe pile, so that the clamping plate 9 is stable when fixed. Furthermore, a fixing post 11 is sleeved on the outer wall of the rectangular post 10, and the outer wall of the fixing post 11 is fixedly connected to the inner wall of the limiting shell 3. A ball bearing 14 is movably connected between the fixing post 11 and the rectangular post 10. In the specific implementation process, it is worth noting that a rectangular groove is provided on the inner wall of the fixed column 11 to allow the rectangular column 10 to move inside it, and also to prevent the rectangular column 10 from rotating under the action of friction between it and the screw 13. The ball bearings 14 between the fixed column 11 and the rectangular column 10 can reduce the friction between them, so that the rectangular column 10 can move laterally stably under the drive of the screw 13, and the clamping plate 9 can be clamped on the outer wall of the pipe pile.

[0021] Example 2: From Figure 1-4 It can be seen that a servo motor 6 is fixedly connected to the outer wall of the protective shell 4. The output end of the servo motor 6 is fixedly connected to a drive rod 17 through a sealed bearing at one end of the protective shell 4. A drive gear 18 is fixedly connected to the outer wall of the drive rod 17. A driven gear 16 is meshed with the outer wall of the drive gear 18. A fixed cylinder 7 is fixedly connected to the inner wall of the driven gear 16. The inner wall of the fixed cylinder 7 is rotatably connected to the inner wall of the protective shell 4 through a bearing. A slider 19 is threadedly connected to the inner wall of the fixed cylinder 7. The outer wall of the slider 19 is fixedly connected to the outer wall of the irrigation pipe 2. In the specific implementation process, it is worth noting that both the driving gear 18 and the driven gear 16 are bevel gears. When the servo motor 6 drives the driving gear 18 to rotate, the meshing of the driving gear 18 and the driven gear 16 drives the fixed cylinder 7 to rotate inside the protective shell 4. The outer wall of the slider 19 is provided with external threads, and the inner wall of the fixed cylinder 7 is provided with internal threads, so that the slider 19 can move on the inner wall of the fixed cylinder 7. When the fixed cylinder 7 rotates, the slider 19 drives the irrigation pipe 2 to extend and retract to adapt to pipe piles of different depths. The model of the servo motor 6 is not limited, as long as it meets the actual use conditions, and it is powered by an external power supply. Furthermore, a limiting post 5 is inserted into the inner wall of the slider 19, and the outer wall of the limiting post 5 is fixedly connected to the inner wall of the protective shell 4. In the specific implementation process, it is worth noting that the outer wall of the limiting post 5 is a smooth surface. This can ensure the stability of the slider 19 when it moves and prevent the slider 19 from shifting under the action of friction between it and the fixed cylinder 7, thereby restricting the lifting and lowering of the irrigation pipe 2.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
