[0022] 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.

[0023] Example 1

[0024] Please see Figure 1-4 The present invention provides the following technical solution: a precast pile positioning and fixing device, including a first clamp 2, a convenient cleaning component 1 fixed on one side surface of the first clamp 2, a second clamp 3 provided on the side of the first clamp 2 away from the convenient cleaning component 1, a clamp splicing component 8 provided between the first clamp 2 and the second clamp 3, a connecting frame 7 symmetrically fixed on one side surface of the first clamp 2, a positioning seat 4 provided at one end of the connecting frame 7, and a positioning hole 5 provided through the interior of the positioning seat 4.

[0025] Specifically, a connecting frame 7 and a positioning seat 4 are symmetrically arranged on one side of the second clamp 3, and a reinforcing plate 6 is arranged in the middle of the interior of the connecting frame 7.

[0026] By adopting the above technical solution, the firmness and stability of the connection between the positioning seat 4 and the clamp are improved.

[0027] Specifically, the clamp splicing assembly 8 includes a movable block 81, a limiting spring 82, a limiting stop 83, a second connecting seat 84, a first connecting seat 85, a fixed seat 86, and a lead screw 87. The second clamp 3 is symmetrically provided with a second connecting seat 84 at one end, and the first clamp 2 is symmetrically provided with a first connecting seat 85 on one side. The fixed seat 86 is fixed inside the first connecting seat 85. The lead screw 87 is provided inside the fixed seat 86. The movable block 81 is provided on the surface of the lead screw 87. The limiting spring 82 is symmetrically provided inside the movable block 81. One end of the limiting spring 82 is connected to the limiting stop 83.

[0028] By adopting the above technical solution, when installing the second clamp 3, it can first be spliced ​​with the first clamp 2, aligning the slot inside the connecting seat 2 84 with the fixed seat 86. Then, the second clamp 3 is pushed to make the connecting seat 2 84 slide along the fixed seat 86. At the same time, the connecting seat 2 84 abuts against the surface of the limiting block 83, causing the limiting spring 82 to be compressed. When the connecting seat 2 84 moves and disengages from the limiting block 83, the limiting spring 82 resets, causing the limiting block 83 to protrude from the movable block 81 and limit and block the connecting seat 2 84. Then, the screw 87 can be rotated to make the movable block 81 slide inside the fixed seat 86, thereby making the connecting seat 2 84 move closer to the connecting seat 1 85 and finally fit firmly with the connecting seat 1 85, ensuring the stability of the splicing of the first clamp 2 and the second clamp 3. In subsequent use, the connecting seat 2 84 can be directly pushed to move along the fixed seat 86 without repositioning, improving the convenience of equipment use, saving manpower, and reducing fixing costs.

[0029] Specifically, the fixing seat 86 is fixed inside the connecting seat 85 by brazing, and the connecting seat 84 has a slot inside corresponding to the fixing seat 86.

[0030] By adopting the above technical solution, the fixing seat 86 is securely installed in the connecting seat 85, thereby improving its strength.

[0031] Specifically, the interior of the fixed seat 86 is designed as a hollow structure, and the inner wall surface of the fixed seat 86 is provided with a bearing corresponding to the lead screw 87.

[0032] By adopting the above technical solution, the rotation of the lead screw 87 is ensured to be stable, so that the movable block 81 can slide along the inside of the fixed seat 86.

[0033] Specifically, a limit slider is provided at one end of the limit block 83 near the limit spring 82, and a guide groove is provided inside the movable block 81 corresponding to the limit slider.

[0034] By adopting the above technical solution, the stability of the limit block 83 is ensured, and its limiting effect on the connecting seat 84 is improved.

[0035] In this embodiment, when positioning and fixing the precast pile, first install the connecting bracket 7 on one side of the first clamp 2 to the fixed point and fix it by bolts through the positioning hole 5. When installing the second clamp 3, it can be spliced ​​with the first clamp 2 first, aligning the slot inside the connecting seat 2 84 with the fixed seat 86. Then push the second clamp 3 to make the connecting seat 2 84 slide along the fixed seat 86. At the same time, the connecting seat 2 84 abuts against the surface of the limiting block 83, causing the limiting spring 82 to be compressed. When the connecting seat 2 84 moves and is aligned with the limiting block 86, the limiting spring 82 is compressed. When disengaged, the limiting spring 82 resets, causing the limiting block 83 to protrude from the movable block 81 and limit and block the connecting seat 2 84. Then, the rotatable screw 87 causes the movable block 81 to slide inside the fixed seat 86, thereby causing the connecting seat 2 84 to move closer to the connecting seat 1 85 and finally fit firmly with the connecting seat 1 85, ensuring the stability of the splicing of the first clamp 2 and the second clamp 3. In subsequent use, the connecting seat 2 84 can be directly pushed to move along the fixed seat 86 without repositioning, improving the convenience of equipment use, saving manpower, and reducing fixing costs.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that: specifically, the convenient cleaning component 1 includes a dust cover box 11, a storage box 12, a hook 14, a stepper motor 15, and a grinding wheel 16. The storage box 12 is fixed to one side of the first clamp 2, the dust cover box 11 is provided inside the storage box 12, the hook 14 is fixed to one end of the dust cover box 11, the stepper motor 15 is provided inside the dust cover box 11, and the grinding wheel 16 is fixed to the output end of the stepper motor 15.

[0038] By adopting the above technical solution, after long-term use, it is necessary to clean the concrete adhering to the surfaces of the first clamp 2 and the second clamp 3 to prevent affecting the positioning effect of the precast pipe pile. Pull the hook 14 to pull the dust cover box 11 out of the storage box 12, and then hang the hook 14 on the edge of the first clamp 2 so that the grinding wheel 16 is in contact with the inner wall surface of the first clamp 2. Then, start the stepper motor 15 to drive the grinding wheel 16 to rotate and grind the adhering concrete. At the same time, the hook 14 can be pushed along the edge of the first clamp 2 to slide, ensuring full coverage cleaning of the inner wall of the first clamp 2, ensuring the convenience and cleaning effect of cleaning, improving the quality of equipment use, and ensuring the positioning accuracy of the precast pile.

[0039] Specifically, the storage box 12 has a strong magnetic block 13 inside corresponding to the hook 14, and the sum of the heights of the hook 14 and the reinforcing plate 6 is the same as the height of the first clamp 2.

[0040] By adopting the above technical solution, it is ensured that after the dust cover box 11 is installed inside the storage box 12, the hook 14 and the strong magnet 13 are attracted and fixed, thus improving the convenience of fixed installation.

[0041] In this embodiment, after prolonged use, the concrete adhering to the surfaces of the first clamp 2 and the second clamp 3 needs to be cleaned to prevent affecting the positioning effect of the precast pipe pile. Pull the hook 14 to remove the dust cover box 11 from the inside of the storage box 12, and then hang the hook 14 on the edge of the first clamp 2 so that the grinding wheel 16 is in contact with the inner wall surface of the first clamp 2. Then, start the stepper motor 15 to drive the grinding wheel 16 to rotate and grind the adhering concrete. At the same time, the hook 14 can be pushed along the edge of the first clamp 2 to slide, ensuring full coverage cleaning of the inner wall of the first clamp 2, ensuring the convenience and cleaning effect of cleaning, improving the quality of equipment use, and ensuring the positioning accuracy of the precast pile.

[0042] The working principle and usage process of this invention: When using this invention to position and fix precast piles, first install the connecting frame 7 on one side of the first clamp 2 to the fixed point and fix it by bolts through the positioning hole 5. When installing the second clamp 3, it can be spliced ​​with the first clamp 2 first, aligning the slot inside the connecting seat 2 84 with the fixed seat 86. Then push the second clamp 3 to make the connecting seat 2 84 slide along the fixed seat 86. At the same time, the connecting seat 2 84 abuts against the surface of the limiting block 83, causing the limiting spring 82 to be compressed. When the connecting seat 2 84 moves and... When the limit stop 83 is disengaged, the limit spring 82 resets, causing the limit stop 83 to protrude from the movable block 81 and limit and block the connecting seat 2 84. Then, the rotatable screw 87 causes the movable block 81 to slide inside the fixed seat 86, thereby causing the connecting seat 2 84 to move closer to the connecting seat 1 85 and finally fit firmly with the connecting seat 1 85, ensuring the stability of the splicing of the first clamp 2 and the second clamp 3. In subsequent use, the connecting seat 2 84 can be directly pushed to move along the fixed seat 86 without repositioning, improving the convenience of equipment use, saving manpower, and reducing fixing costs.

[0043] After prolonged use, the concrete adhering to the surfaces of the first clamp 2 and the second clamp 3 needs to be cleaned to prevent affecting the positioning effect of the precast pipe pile. Pull the hook 14 to remove the dust cover box 11 from the inside of the storage box 12, and then hang the hook 14 on the edge of the first clamp 2 so that the grinding wheel 16 is in contact with the inner wall surface of the first clamp 2. Then start the stepper motor 15 to drive the grinding wheel 16 to rotate and grind the adhering concrete. At the same time, the hook 14 can be pushed along the edge of the first clamp 2 to slide, ensuring full coverage cleaning of the inner wall of the first clamp 2, ensuring the convenience and cleaning effect of cleaning, improving the quality of equipment use, and ensuring the positioning accuracy of the precast pile.
