Description

Technical Field

[0001] This utility model relates to the field of pipe pile design technology, and in particular to a detachable pipe pile. Background Technology

[0002] In the field of foundation construction, pipe piles are an important structural component. Pipe piles are typically designed as a single unit, meaning their length is fixed during production and cannot be adjusted to meet actual construction needs. While this design offers advantages in structural stability, it presents numerous inconveniences during actual construction.

[0003] First, traditional pipe piles have a fixed length, which cannot be flexibly adjusted according to the specific needs of the construction site. When the construction site conditions change, it may be necessary to replace the pipe piles with different lengths, which not only increases construction costs but also extends the construction period.

[0004] Secondly, based on the experience of the main technical personnel in the applicant's multiple construction projects, it was found that in urban renewal or old building demolition projects, some areas require the pre-installation of some pipe piles for foundation construction. After the completion of some foundation construction, some of the pre-installed pipe piles need to be removed. However, due to the fixed length of the existing pipe pile structure, they cannot be removed. Dismantling them is extremely difficult, requiring complex crushing, and some may even damage the surrounding environment and facilities. This also leads to a decrease in the reuse rate of pipe piles and increases construction costs.

[0005] Therefore, the inventors of the applicant proposed a detachable pipe pile to solve the problem through various innovative improvements. Utility Model Content

[0006] This utility model provides a detachable pipe pile, which solves the problems mentioned in the background.

[0007] To solve the above-mentioned technical problems, this utility model provides a detachable pipe pile, including a pipe body, wherein the pipe body is a pipe body in which two sections are connected together. The pipe body is characterized in that: each connecting end is provided with a connecting plate and a connecting pipe; one end of the pipe body is attached to the connecting plate; the connecting plate is fixed to the outer wall of the connecting pipe and the connecting pipe passes through the pipe body; the end face of the pipe body and the end face of the connecting plate are respectively provided with corresponding openings and rod holes; the outer wall of the connecting pipe is also provided with a splicing assembly of a retractable positioning rod, which connects or disconnects the two pipe bodies and the openings and rod holes of the connecting plate by extending or retracting the positioning rod.

[0008] The splicing assembly includes a ring plate one sleeved on the outer wall of the connecting pipe. A bidirectional internally threaded pipe is rotatably installed on the ring plate one. The bidirectional internally threaded pipe has two screws with opposite thread directions connected internally. A positioning rod is fixed to the outer end of the screw. The positioning rod passes through the connecting disc rod hole and can be inserted into the opening of the pipe body. A ring plate two is rotatably installed on the outer wall of the ring plate one. The ring plate two is connected to the bidirectional internally threaded pipe and a driving assembly is used to drive the ring plate two and the bidirectional internally threaded pipe to rotate synchronously.

[0009] The drive assembly includes a toothed block disposed on the inner wall of the second drive ring plate. Gears are provided around the periphery of the internally threaded tube. The toothed block meshes with the gears. The gears are fixed outside the bidirectional internally threaded tube and located below the first ring plate.

[0010] The inner wall of the second driving ring plate is fixed with an annular slider, which slides in the opening of the outer wall of the first ring plate.

[0011] The splicing assembly also includes a ring plate three sleeved on the outer wall of the connecting pipe. The ring plate three fits against the bottom of the ring plate two and is located below the gear. The bidirectional internal threaded tube passes through the circular hole of the ring plate three. The two are close but do not contact each other. A sealing gasket is provided on the inner wall of the circular hole to contact the outer wall of the bidirectional internal threaded tube.

[0012] A connecting piece is fixed to the top of the two end faces of the ring plate. The connecting piece is also attached to the top of the ring plate. After the connecting piece rotates a certain angle, its screw hole is aligned with the screw hole on the surface of the ring plate (31).

[0013] The diameter of the positioning rod is larger than that of the screw. The outer wall of the positioning rod is provided with a row of protruding strips, and the inner wall of the connecting rod hole and the opening of the tube body are provided with grooves corresponding to the protruding strips.

[0014] The connecting plate is fixedly connected to the connecting pipe with a row of triangular blocks.

[0016] This utility model provides a detachable pipe pile. By adopting the design of splicing components and driving components, the pipe pile structure can be disassembled more conveniently when needed.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As shown in the figure, Figures 1-6 This utility model includes a tube body 1, which is a tube body 1 consisting of two connected sections. Each end of the tube body 1 is provided with a connecting plate 2 and a connecting pipe 21. One end of the tube body 1 is attached to the connecting plate 2. The connecting plate 2 is fixed to the outer wall of the connecting pipe 21 and the connecting pipe 21 is inserted into the tube body 1. The end face of the tube body 1 and the end face of the connecting plate 2 are respectively provided with corresponding openings and rod holes. The outer wall of the connecting pipe 21 is also provided with a splicing assembly 3 of a retractable positioning rod 34. The two tube bodies 1 and the connecting plate 2 are connected or disconnected by extending or retracting the positioning rod 34 to the openings and rod holes of the connecting plate 2.

[0026] The splicing assembly 3 includes a ring plate 31 fixed to the outer wall of the connecting pipe 21. A bidirectional internal threaded pipe 32 is rotatably installed on the ring plate 31. The bidirectional internal threaded pipe 32 is internally threaded with two screws 33 with opposite thread directions. A positioning rod 34 is fixed to the outer end of the screw 33. The positioning rod 34 passes through the rod hole of the connecting plate 2 and can be inserted into the opening of the pipe body 1. A ring plate 35 is rotatably installed on the outer wall of the ring plate 31. A driving assembly 4 is connected to the bidirectional internal threaded pipe 32 and the ring plate 35 to drive the ring plate 35 and the bidirectional internal threaded pipe 32 to rotate synchronously. An annular slider 38 is fixed to the inner wall of the driving ring plate 35 and slides in the opening on the outer wall of the ring plate 31.

[0027] The drive assembly 4 includes a toothed block 42 disposed on the inner wall of the drive ring plate 2 35. The toothed block 42 meshes with a gear 41, which is fixed outside the bidirectional internal thread tube 32 and located below the ring plate 1 31.

[0028] As described above, through the design of splicing component 3 and driving component 4, the original integral tube 1 is divided into several sections during installation and docking. These sections can be two-end, three-end, or more. During splicing, one end of tube 1 is initially fixed to the connecting pipe 21 via connecting plate 2. The connecting pipe 21 is then inserted into another section of tube 1 to be spliced. Subsequently, by operating driving component 4, i.e., rotating ring plate 2 35, the meshing action of toothed block 42 and gear 41 drives the bidirectional internal thread tube 32 to rotate synchronously. The two screws 33 with opposite thread directions connected inside the bidirectional internal thread tube 32 will move in opposite directions, thereby driving the positioning rod 34 to move. This allows the positioning rod 34 to pass through the rod hole of connecting plate 2 and insert into the opening of tube 1, achieving a stable docking between tube 1 and connecting plate 2. Due to the design of bidirectional internal thread tube 32, it is possible to drive two positioning rods 34 to move in opposite directions or in opposite directions simultaneously, improving docking efficiency and stability.

[0029] A ring plate 36 is fixed to the outer wall of the connecting pipe 21. The ring plate 36 fits against the bottom of the ring plate 25 and is located below the gear 41. The bidirectional internal threaded tube 32 passes through the round hole of the ring plate 36. The two are close but do not contact each other. A sealing gasket is set on the inner wall of the round hole to contact the outer wall of the bidirectional internal threaded tube 32. A connecting piece 37 is fixed to the top of the ring plate 25. The connecting piece 37 also fits against the top of the ring plate 11. After the connecting piece 37 rotates a certain angle (at which point the overall splicing is just completed), its own screw hole is aligned with the screw hole on the surface of the ring plate 11.

[0030] Furthermore, the design of the connecting piece 37 not only allows it to fit snugly against the top of ring plate 31, but also, after rotation at a certain angle and completion of assembly, allows it to be fixed with screws passing through its own screw holes and those on the surface of ring plate 31. This strengthens the connection between ring plate 35 and ring plate 31, preventing unnecessary rotation of ring plate 35 during long-term use or under external force, ensuring the stability and reliability of the splicing assembly 3 and the drive assembly 4. The ring plate 36 effectively prevents external impurities or moisture from entering the space between gear 41 and gear block 42, protecting the precision components of the drive assembly 4 and extending the overall lifespan of the device. Disassembly is simple: first remove the screws from the connecting piece, then rotate ring plate 37 in the opposite direction, greatly simplifying the disassembly process, reducing construction costs, and increasing the flexibility of construction and use.

[0031] The diameter of the positioning rod 34 is larger than that of the screw 33. The outer wall of the positioning rod 34 is provided with a row of protruding strips, and the inner wall of the rod hole of the connecting plate 2 and the opening of the tube body 1 are provided with grooves corresponding to the protruding strips.

[0032] Furthermore, with this design, the screw 33 and the positioning rod 34 cannot rotate, allowing the positioning rod 34 to move smoothly up and down when the bidirectional internal thread tube 32 rotates.

[0033] The connecting plate 2 is fixedly connected to the connecting pipe 21 with a row of triangular blocks 22, and is solid in design.

[0034] Furthermore, the triangular block 22 strengthens the connection between the connecting plate 2 and the connecting pipe 21, thereby improving the connection strength between the connecting plate 2 and the connecting pipe 21 as intermediate components.

[0035] The above structure can fully realize the following: by adopting the design of splicing components and driving components, the pipe pile structure can be disassembled more conveniently when it needs to be disassembled. It can be connected and disassembled according to the length requirements of the pipe piles. Compared with the traditional integral design of pipe piles, it is more flexible and practical. By simply applying force to rotate the ring plate of the driving component connected to the splicing component in the forward and reverse directions, the positioning rod can be extended or retracted to connect or disconnect the two pipe piles, thereby greatly simplifying the disassembly process, reducing construction costs and increasing the flexibility of construction and use.
