Description

Technical Field

[0001] This utility model relates to a mobile positioning device for precast pile driving, belonging to the field of building construction technology. Background Technology

[0002] In existing sediment pile construction, composite piles are increasingly being used. According to the design requirements of the composite pile foundation structure, the YTB connecting piles and ZSP load-bearing piles must interlock and be connected face-to-face, bearing load synchronously to form a continuous pile wall, thus ensuring that the bank embankment is not eroded by river water and suffers soil loss. In conventional pile driving construction, levels and total stations are usually set up on the bank to coordinate positioning and elevation control, ensuring the pile position and verticality. However, during construction, hammer vibration or continuous movement of machinery often affects the accuracy of pile position and verticality control, resulting in low efficiency in construction quality control. Furthermore, the standards for pile position and verticality control during construction are high; otherwise, large gaps and deviations between the composite piles can easily occur, affecting the overall stability of the revetment. Utility Model Content

[0003] The purpose of this invention is to provide a mobile positioning device for driving precast piles to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mobile positioning device for precast pile driving, wherein the mobile positioning guide device comprises:

[0005] The moving component includes a pair of parallel square steel sections and a pair of circular steel sections respectively fitted inside the square steel sections. The square steel sections are provided with several guide structures at equal intervals.

[0006] The positioning assembly includes a horizontal positioning structure and a vertical positioning structure disposed at the end of the circular steel section. The vertical positioning structure includes a square positioning bracket and a pair of driven rollers. A pile driving space is formed inside the square positioning bracket, and the pair of driven rollers are arranged at intervals in the pile driving space along the vertical direction.

[0007] The support assembly includes a fixed bracket disposed at one end of the square steel section near the positioning component and a counterweight disposed at one end of the square steel section away from the positioning component. The fixed bracket is attached to the precast pile cap that has been constructed, and the counterweight is erected on a temporary platform.

[0008] Furthermore, the guide structure includes a ball bearing roller that is slidably connected to the inner wall of the square steel section and ball bearings arranged diagonally along the square steel section for securing.

[0009] Furthermore, the horizontal positioning structure includes an I-shaped connecting frame, the length of which is equal to the spacing between the piles.

[0025] Please refer to Figures 1 to 3The mobile positioning device for driving precast piles shown in one embodiment of this application includes a moving component 10, a positioning component 30, and a supporting component 20.

[0026] The moving component 10 includes a pair of parallel square steel sections 11 and a pair of circular steel sections 12 respectively fitted inside the square steel sections 11. Several guide structures are arranged at equal intervals on the square steel sections 11. The positioning structure is configured to restrict the circular steel sections 12 to move only along the axial direction of the square steel sections 11.

[0027] The positioning assembly 30 includes a horizontal positioning structure 31 and a vertical positioning structure 32 disposed at the end of the circular steel section 12. The vertical positioning structure 32 includes a square positioning bracket and a pair of driven rollers 323. A pile driving space is formed in the square positioning bracket, and the pair of driven rollers 323 are arranged at intervals in the vertical direction in the pile driving space.

[0028] The support component 20 includes a fixed bracket set at one end of the square steel 11 near the positioning component 30 and a counterweight set at the other end of the square steel 11 away from the positioning component 30. The fixed bracket is attached to the precast pile cap that has been constructed, and the counterweight is placed on a temporary platform.

[0029] In one embodiment, the guide structure includes a ball bearing roller 121 slidably connected to the inner wall of the square steel section 11 and ball bearing retainers 122 arranged diagonally along the square steel section 11. This arrangement effectively reduces the friction between the round steel section 12 and the square steel section 11 while limiting the direction of movement of the round steel section 12.

[0030] In one embodiment, the horizontal positioning structure 31 includes an I-shaped connecting frame, the length of which is equal to the spacing between the piles. This facilitates determining the pile position using the I-shaped connecting frame, reduces the adjustment process, and improves construction efficiency.

[0031] In one embodiment, the horizontal positioning structure 31 includes a positioning steel section sleeved on the circular steel section 12. The positioning steel section is slidably connected to the guide structure, and the positioning steel section and the circular steel section 12 are fixedly connected by a positioning pin. This facilitates the replacement of positioning components 30 of different specifications.

[0032] In one embodiment, the square positioning bracket includes a pair of connecting rods 321 connected to the ends of the I-shaped connecting frame and a fixing plate 322 connected to the ends of the connecting rods 321, with a pair of driven rollers 323 arranged on the fixing plate. The driven rollers 323 restrict the position of the pile and reduce the friction between the pile and the square positioning bracket.

[0033] In one embodiment, the counterweight includes a counterweight steel pipe disposed at the end of the square steel section 11 and a round steel bar detachably disposed inside the counterweight steel pipe. By replacing the round steel bar, the support assembly 20 is kept horizontal, preventing one end of the round steel section 12 from tilting up and affecting the pile top height difference.

[0034] In one embodiment, an anti-detachment structure 40 is provided at the end of the circular steel section 12. The anti-detachment structure 40 is used to restrict the end of the circular steel section 12 from entering the square steel section 11. This prevents the circular steel section 12 from being completely pulled out of the square steel section 11, which would require reassembly of the movable positioning guide device.

[0035] In one embodiment, the anti-detachment structure 40 is a triangular stop block with a through hole. The through hole facilitates the insertion of the traction buckle, thereby enabling the circular steel section 12 to move.

[0036] This application sets up a support component on the completed precast pile cap and temporary platform to support the moving component. The guide structure drives the circular steel to move only along the axis of the square steel, thereby driving the positioning component to move along the pile driving position line. This controls the position and verticality of the subsequent adjacent piles, solves the problem of low measurement and positioning efficiency in adverse environmental conditions, reduces the workload and safety hazards of pile driving quality control, and greatly reduces the rework cost of construction.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
