Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary structure technology for bridge construction, and more specifically, to a steel pipe pile clamping structure. Background Technology
[0002] As bridge technology continues to improve, construction difficulty also increases. Under different construction conditions, the form of bridge support will also be changed accordingly to ensure construction safety.
[0003] Existing bridge construction support structures can solve the problems caused by the inability to directly construct supports using only full-span supports or steel pipe piles plus Bailey beam supports in certain complex working conditions. However, when the steel pipe piles are long, they may tilt, causing deviations in the stress distribution of the entire support structure, which may affect the bridge construction.
[0004] A search revealed a Chinese patent with publication number CN208362929U that discloses a steel pipe support structure. When the steel pipe pile tends to tilt, the limiting block abuts against the steel pipe pile, providing support force to the steel pipe pile, reducing the probability of the steel pipe pile tilting, and reducing the impact of the steel pipe pile tilting on bridge construction.
[0005] However, in actual use, the support structure of the above-mentioned structure concentrates the support of the steel pipe piles on a single horizontal point for a long time, which puts great pressure on the contact surface of the steel pipe piles and easily causes stress concentration, resulting in instability of the support of the steel pipe piles themselves. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel pipe pile clamping structure to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A steel pipe pile clamping structure includes a connecting frame one, a rotating shaft fixedly connected to the inner side of the connecting frame one, a connecting frame two rotatably connected to the outer side of the rotating shaft, and a connecting frame two slidably connected to the outer side of the connecting frame one. Both ends of the connecting frame one and the connecting frame two are equipped with clamping mechanisms. Each clamping mechanism includes a connecting rod one, a bolt one inserted into one side of the connecting rod one, a connecting rod two slidably connected to the inner side of the connecting rod one, multiple insertion holes one on the inner side of the connecting rod two, the inner side of the insertion holes one being inserted into the inner side of the bolt one, a positioning shaft fixedly connected to one side of the connecting rod two, a fixed wheel fixedly connected to the outer side of the positioning shaft, and multiple slots on the outer side of the fixed wheel. A rotating seat is rotatably connected to the outer side of the positioning shaft. A clamping plate is fixedly connected to one side of the rotating seat. An outer cylinder is fixedly connected to one side of the clamping plate. A spring is fixedly connected to the inner side of the outer cylinder. A push block is fixedly connected to one side of the spring. The outer side of the push block is slidably connected to the inner side of the outer cylinder. An insertion rod is fixedly connected to the inner side of the push block. The outer side of the insertion rod is slidably connected to the inner side of the clamping plate. A push plate is fixedly connected to one side of the insertion rod. A pad is fixedly connected to the outer side of the push plate. One end of the insertion rod is inserted into the inner side of the slot. Multiple bolts are inserted into the outer side of the clamping plate. A clamping plate is inserted into one side of each bolt. A cross support mechanism is provided on the outer side of the connecting frame.
[0009] By adopting the above technical solution: the rotation of clamping plate one and clamping plate two allows clamping plate one to better fit with the surface of the steel pipe pile, and the force of fastening clamping plate one and clamping plate two allows the insertion rod to be inserted into the slot in time, and the rotated clamping plate one and clamping plate two can be fixed with the corresponding connecting rod one in time, thereby improving the applicability of the pile clamping structure.
[0010] As a further description of the above technical solution: the cross support mechanism includes two positioning discs, the outer side of the positioning discs is fixedly connected to the inner side of the connecting frame one, the outer side of the positioning discs is provided with multiple insertion holes two, the inner side of the connecting frame two is inserted with bolts three, and the outer side of the bolts three is inserted into the inner side of the insertion holes two.
[0011] By adopting the above technical solution, the parallel support of the pile clamping mechanism is transformed into a triangular support by utilizing the cross rotation of connecting frame one and connecting frame two, thereby improving the compressive strength of the pile clamping mechanism for supporting the steel pipe pile.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. By setting up a pile clamping mechanism, compared with the existing technology, multiple clamping plates 1 and 2 that can deflect at different angles are used to clamp the steel pipe pile at different angles, so that the support point of the pile clamping mechanism for the steel pipe pile is changed from one to two, so that the pressure on the steel pipe pile is distributed to two points. Furthermore, the timely insertion of the push plate and the insertion rod is used to improve the stability of the pile clamping mechanism for the steel pipe pile while maintaining a certain degree of flexibility.
[0014] 2. By setting up a cross-support mechanism, compared with the existing technology, the rotation of connecting frame one and connecting frame two allows the two sets of connecting rods to cross-support each other, turning the straight support between the two steel pipe piles into multi-point support. Furthermore, by utilizing the stability of the triangle, the pile clamping mechanism has a stronger bearing capacity. Attached Figure Description

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.
[0023] The embodiments disclosed in this application are as follows: Figure 1-6The steel pipe pile clamping structure shown includes a connecting frame 1, a rotating shaft 2 fixedly connected to the inner side of the connecting frame 1, a connecting frame 2 rotatably connected to the outer side of the rotating shaft 2, and a connecting frame 3 slidably connected to the outer side of the connecting frame 2 and the inner side of the connecting frame 1. Both ends of the connecting frame 1 and the connecting frame 2 are equipped with clamping mechanisms. The clamping mechanism includes a connecting rod 4, a bolt 5 inserted into one side of the connecting rod 4, a connecting rod 6 slidably connected to the inner side of the connecting rod 4, and multiple insertion holes 7 opened on the inner side of the connecting rod 6. The inner side of the insertion holes 7 is inserted into the inner side of the bolt 5. A positioning shaft 22 is fixedly connected to the side. A fixed wheel 23 is fixedly connected to the outside of the positioning shaft 22. Multiple slots 8 are provided on the outside of the fixed wheel 23. A rotating seat 9 is rotatably connected to the outside of the positioning shaft 22. A clamping plate 10 is fixedly connected to one side of the rotating seat 9. An outer cylinder 11 is fixedly connected to one side of the clamping plate 10. A spring 12 is fixedly connected to the inside of the outer cylinder 11. A push block 13 is fixedly connected to one side of the spring 12. The outside of the push block 13 is slidably connected to the inside of the outer cylinder 11. An insertion rod 14 is fixedly connected to the inside of the push block 13. The outside of the insertion rod 14 is connected to the clamping plate 10. The inner side of the 0 sliding connection is provided. A push plate 15 is fixedly connected to one side of the insertion rod 14, and a pad 16 is fixedly connected to the outer side of the push plate 15. One end of the insertion rod 14 is inserted into the inner side of the slot 8. Multiple bolts 17 are inserted into the outer side of the clamping plate 10, and a clamping plate 18 is inserted into one side of the bolts 17. A cross support mechanism is provided on the outer side of the connecting frame 1. The connecting rod 6 extends out from the inner side of the connecting rod 4, and the connecting rod 4 and the connecting rod 6 are inserted and positioned by passing through the insertion hole 7 through the corresponding bolts 5. Then, the clamping plate 10 is inserted through the rotating seat 9 on one side. Rotating outward from the positioning shaft 22 allows the clamping plate 10 to clamp the second plate 18 and make it fit against the surface of the steel pipe pile. The steel pipe pile pushes the inner push plate 15 and pad 16 of the clamping plate 10, causing the insertion rod 14 to compress the spring 12. At the same time, one end of the insertion rod 14 is inserted into the corresponding slot 8 on the outside of the fixing wheel 23, so that the clamping plate 10 and the connecting rod 26 can be fixed in time after deflection at a certain angle, so that the clamping plate 10, the clamping plate 28 and the connecting rod 4 have good pressure bearing capacity.
[0024] Reference Figure 2 and Figure 4 As shown, the cross support mechanism includes two positioning plates 19. The outer side of the positioning plates 19 is fixedly connected to the inner side of the connecting frame 1. Multiple insertion holes 20 are opened on the outer side of the positioning plates 19. Bolts 21 are inserted into the inner side of the connecting frame 2. The outer side of the bolts 21 is inserted into the inner side of the insertion holes 20. By pulling the bolts 21 out from the inner side of the positioning plates 19 and the connecting frame 2.3, the cross angle of the connecting frame 1 and the connecting frame 2.3 can be adjusted according to the spacing between the steel pipe piles, so that the connecting frame 1 and the connecting frame 2.3 maintain a strong supporting force and compressive strength between the two steel pipe piles.
[0025] The working principle of this utility model is as follows: When supporting steel pipe piles, firstly, multiple bolts 5 are pulled out from the inside of connecting rod 4 and connecting rod 6, allowing multiple connecting rods 6 to extend from the inside of connecting rod 4. After reaching a suitable length, multiple bolts 5 are reinserted into the corresponding insertion holes 7 inside connecting rod 4 and connecting rod 6. Then, two bolts 21 are pulled out from the inside of positioning plate 19 and connecting frame 3. Next, connecting frame 1 and connecting frame 2 are adjusted via rotating shaft 2 according to the distance between the two steel pipe piles, so that the distance between the two sets of clamping plates 10 and clamping plates 18 at both ends of connecting frame 1 and connecting frame 2 is the same as the distance between the two steel pipe piles. Then, multiple bolts 217 between the two sets of clamping plates 10 and clamping plates 18 are removed. Then, the clamping plates 10 corresponding to the outer sides of multiple connecting rods 4 and connecting rod 2 are brought closer to one side of the steel pipe pile, and the two rotating shafts on one side of clamping plate 10 are used to... The seat 9 rotates outside the corresponding positioning shaft 22, allowing the corresponding clamping plate 10 to fit against the surface of the steel pipe pile. Then, the corresponding clamping plate 2 18 clamps the outer side of the steel pipe pile from one side of the clamping plate 10. Multiple bolts 2 17 are then used to tighten the clamping plates 10 and 2 18 together. While the clamping plates 10 and 2 18 are tightened to clamp the steel pipe pile using the bolts 2 17, the push plate 15 and pad on the inner side of the clamping plate 10... Under the pressure of the steel pipe pile, the insert rod 14 and the push block 13 will push the spring 12. At the same time, one end of the insert rod 14 will be inserted into the slot 8 at the corresponding angle after the clamping plate 10 is rotated, so that the clamping plate 10 can be fixed with the connecting rod 2 6 in time after the deflection angle is fixed. Multiple clamping plates 10 and clamping plates 2 18 are supported by the connecting frame 1 and connecting frame 2 3 through the corresponding two connecting rods 1 4, and finally the support between the steel pipe piles is completed.
