Description

Technical Field

[0001] The utility model relates to the technical field of pipe piles, in particular to a precise positioning device for high-strength prestressed pipe piles. Background Technique

[0002] When carrying out the embedding work of pipe piles, if the height of the pipe pile is not enough, another pipe pile needs to be spliced to increase the height. When splicing two pipe piles, it is difficult to accurately align the end face of the basic pipe pile with the end face of the extended pipe pile, resulting in a reduction in the structural stability of the extended pipe pile. The extended pipe pile is prone to shaking, leading to inaccurate positioning.

[0003] During the splicing and installation of existing pipe piles, the positioning is inaccurate, resulting in a reduction in the stability of the splicing and installation of the two pipe piles. Moreover, the outer side of the pipe pile is usually a ring-shaped positioning mechanism, which is usually sleeved on the outer side of the pipe pile and is prone to sliding or offset. The disassembly and installation operations of the positioning mechanism are relatively cumbersome, making it inconvenient to replace the damaged positioning mechanism and affecting the practicability of the splicing and installation of the two pipe piles. Therefore, those skilled in the art have provided a precise positioning device for high-strength prestressed pipe piles to solve the problems raised in the above background technique.

Fixing parts 6 are respectively connected to both ends of the first mounting ring 4 and the second mounting ring 5. A positioning assembly is installed between the first pipe pile 1 and the second pipe pile 2, and a lock - catch assembly is installed between the two fixing parts 6.

[0026] During use, both the first mounting ring 4 and the second mounting ring 5 are arc-shaped. The fixing ring 3 can support and fix the first mounting ring 4 and the second mounting ring 5. The two first mounting rings 4 are installed through the fixing parts 6 at both ends. Similarly, the two second mounting rings 5 are installed through the fixing parts 6 at both ends, improving the convenience of disassembling and replacing the first mounting ring 4 and the second mounting ring 5.

[0027] In one embodiment, specifically, the positioning assembly includes a plurality of positioning blocks 7 evenly arranged on the top of the first mounting ring 4. A plurality of positioning grooves 8 arranged in a circle are formed at the bottom of the second mounting ring 5. A plurality of limiting blocks 9 arranged in a circle are installed on the inner sides of the first mounting ring 4 and the second mounting ring 5. A plurality of limiting grooves 10 arranged in a circle are respectively formed on the outer sides of the first pipe pile 1 and the second pipe pile 2. The positioning blocks 7 are movably connected to the positioning grooves 8.

[0028] Among them, when the first mounting ring 4 and the second mounting ring 5 are spliced and installed, the positioning blocks 7 are embedded in the positioning grooves 8, so that the plurality of positioning blocks 7 accurately position the first pipe pile 1 and the second pipe pile 2, preventing the first pipe pile 1 and the second pipe pile 2 from shifting. The plurality of limiting blocks 9 on the inner sides of the first mounting ring 4 and the second mounting ring 5 are respectively embedded in the limiting grooves 10 on the outer sides of the first pipe pile 1 and the second pipe pile 2, preventing the first mounting ring 4 and the second mounting ring 5 from sliding or shifting on the outer sides of the first pipe pile 1 and the second pipe pile 2, improving the stability and strength of the splicing and installation of the first pipe pile 1 and the second pipe pile 2.

[0029] Furthermore, the locking component includes a sliding block 11 connected to one side of one of the fixing parts 6. A sliding groove 12 is formed on one side of the other fixing part 6. A sliding through hole 13 is formed on the other side of the sliding groove 12. Locking grooves 14 are respectively formed on both sides of the sliding through hole 13. The locking component includes a movable cavity 15 formed on one side of the sliding block 11. A screw rod 16 penetrates through the inner side of the movable cavity 15. A locking block 17 is connected to the outer side of the screw rod 16. An anti-detachment part 18 is connected to one end of the screw rod 16. A spring 19 for extrusion and pushing is sleeved on the inner side of the movable cavity 15 and outside the screw rod 16. One end of the spring 19 is connected to a sliding ring 20. Both ends of the spring 19 are fixedly connected to the movable cavity 15 and the sliding ring 20 respectively. The anti-detachment part 18 is slidably connected to the movable cavity 15 and does not detach. The screw rod 16 is screwed to the movable cavity 15. The sliding block 11 is movably connected to the sliding groove 12.

[0030] In one embodiment, specifically, the cross-sections of the sliding block 11 and the sliding groove 12 are both "convex" in shape. The sliding groove 12 can limit the sliding block 11 to prevent the sliding block 11 from disengaging from the sliding groove 12. When the sliding block 11 slides in the sliding groove 12, the screw 16 on one side of the sliding block 11 slides on one side of the sliding through-hole 13. The anti-disengagement portion 18 can prevent the screw 16 from disengaging and limit its position, avoiding the separation of the screw 16 from the sliding block 11. The spring 19 in the movable cavity 15 can squeeze and push the sliding ring 20, and the sliding ring 20 squeezes and pushes the anti-disengagement portion 18, improving the strength and stability of the locking block 17 to lock and fix the sliding block 11. The screw 16 drives the locking block 17 to be inserted into the locking groove 14, so that the locking block 17 locks and fixes the sliding block 11 again, improving the convenience of disassembling and assembling the first mounting ring 4 and the second mounting ring 5 for replacement.

[0031] Wherein, a first baffle 21 is connected to the top of the first mounting ring 4, and a second baffle 22 is connected to the bottom of the second mounting ring 5. The first baffle 21 and the second baffle 22 are in contact with each other. The cross-sections of the first baffle 21 and the second baffle 22 are both L-shaped. The first baffle 21 and the second baffle 22 are mutually attached and can wrap and block the outside of the joint of the first pipe pile 1 and the second pipe pile 2, improving the strength and sealing performance of the splicing of the first pipe pile 1 and the second pipe pile 2.

[0032] The working principle of the present utility model:

[0033] First, put two first mounting rings 4 on the outside of the first pipe pile 1, then insert the limiting block 9 inside the first mounting ring 4 into the limiting groove 10 on the outside of the first pipe pile 1. Then, the fixing portions 6 at both ends of the two first mounting rings 4 are in contact with each other. Then, the sliding block 11 on one side of the fixing portion 6 is inserted into the sliding groove 12 and slides downward. At this time, the screw 16 on one side of the sliding block 11 slides on one side of the sliding through-hole 13. Then, rotate the screw 16 to drive the locking block 17 to be inserted into the locking groove 14. At the same time, the anti-disengagement portion 18 prevents the screw 16 from disengaging and limits its position. At the same time, the spring 19 in the movable cavity 15 squeezes and pushes the sliding ring 20, and the sliding ring 20 squeezes and pushes the anti-disengagement portion 18. Then, the locking block 17 locks and fixes the sliding block 11 again. Similarly, two second mounting rings 5 can be installed on the outside of the second pipe pile 2. Then, splice and install the first pipe pile 1 and the second pipe pile 2. Then, the positioning block 7 on the top of the first mounting ring 4 is inserted into the positioning groove 8 at the bottom of the second mounting ring 5, and at the same time, the first baffle 21 and the second baffle 22 are mutually attached.
