Description

Technical Field

[0001] This utility model relates to the field of pipe pile technology, specifically to a pipe pile conveying hoisting tool for the pipe pile industry. Background Technology

[0002] Pipe piles are hollow cylindrical reinforced concrete components that are prefabricated in a factory. They are driven, pressed, or screwed into the ground using specialized equipment to serve as deep foundations for buildings, transferring the load of the superstructure to deep, solid soil or rock layers.

[0003] During construction, pipe piles are typically hoisted using cranes or similar equipment to move them to the designated location and then place them. However, the lifting devices used on current cranes to fix pipe piles are often unable to hold them stably, or the connection to the pipe piles is cumbersome and requires many steps, especially the binding of steel wire ropes. If the operation is not done properly, the pipe piles may become unstable, affecting safety. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pipe pile conveying hoist for the pipe pile industry. By hoisting, the clamping parts on the first clamping rod and the second clamping rod can be brought inward to perform multi-point clamping and fixing. The positioning seat can axially position it, thereby solving the problems mentioned in the background art.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a pipe pile conveying lifting device for the pipe pile industry, including a central rod 1 and multiple tie rods 2. The central rod 1 and multiple tie rods 2 are distributed in a triangular structure. Multiple clamping components are installed on the tie rods 2. Each clamping component includes a first clamping rod 3 and a second clamping rod 4. One end of the first clamping rod 3 and the second clamping rod 4 is bent to form a clamping part 14. The clamping parts 14 are combined to form a clamping cavity for clamping the pipe pile. A connecting component is installed between the first clamping rod 3 and the second clamping rod 4. A positioning component for axially positioning the pipe pile is installed on the outermost clamping component.

[0022] In this embodiment, the connecting components all include a connecting seat 6, multiple shafts and multiple bearings 7. The connecting seat 6 is disposed between the first clamping rod 3 and the second clamping rod 4. The first clamping rod 3 and the second clamping rod 4 are provided with mounting holes in the middle. Multiple bearings 7 are installed in the mounting holes. The shafts are respectively installed at both ends of the connecting seat 6. The other end of the shafts extends into the mounting holes and is installed in the inner ring of the bearings 7.

[0023] In this embodiment, the positioning components all include screws 10, nuts 12, and positioning seats 11. The screws 10 are all mounted on the outermost shaft. The positioning seats 11 are all provided with fixing holes. The positioning seats 11 are all sleeved on the screws 10 through the fixing holes. The inner side of the positioning seats 11 all protrudes to form an insertion part 13. The diameter of the insertion part 13 matches the inner diameter of the pipe pile. The nuts 12 are all threaded to the screws 10, and the nuts 12 are all located on the outer side of the positioning seats 11.

[0024] In this embodiment, steel wire ropes 5 are installed between the first clamping rod 3 and the second clamping rod 4 and the centering rod 1, and multiple fixing rings 8 for lifting the device are installed on the centering rod 1.

[0025] In this embodiment, a telescopic rod 9 is installed on any of the connecting seats 6. The other end of the telescopic rod 9 is fixedly connected to the centering rod 1. The telescopic rod can position the centering rod so that the centering rod is centered. Then, after the centering rod moves upward, it can pull the pull rod inward so as to realize the synchronous approach of the first clamping rod and the second clamping rod.

[0026] In this embodiment, both the first clamping rod 3 and the second clamping rod 4 are arranged in a scissor-like structure.

[0027] In this embodiment, a counterweight is installed on the centering rod 1. The counterweight allows the centering rod to descend along the telescopic rod and loosens the steel wire rope connected to it, thereby enabling the first clamping rod and the second clamping rod to open outward smoothly.

[0028] Working principle:

[0029] The lifting device is placed on top of the horizontally placed pipe pile and in contact with the pipe pile. At this time, the pull rope used to connect with the crane is in a relaxed state, and the counterweight on the centering rod can lower the centering rod, thereby relaxing the wire rope connected to the first clamping rod and the second clamping rod. At this time, the first clamping rod and the second clamping rod can open and be sleeved on the outside of the pipe pile, and the insertion part 13 on the outermost positioning seat 11 is aligned with the openings at both ends of the pipe pile.

[0030] Rotate the nut 12 to push the positioning seat 11 to move inward along the screw 10, so that the insertion part 13 is inserted into the inner hole at the end of the pipe pile. Through the joint action of the insertion parts 13 of the positioning seats 11 at both ends, the axial movement of the pipe pile is restricted, and the initial axial fixation is achieved. This operation is very clear and convenient.

[0031] After the above is completed, the lifting equipment lifts the centering rod 1 upward through the fixed ring 8. As the centering rod 1 rises, the steel wire rope 5 and the telescopic rod 9 pull each tie rod 2 toward the center. The inward movement of the tie rod 2 pushes the first clamping rod 3 and the second clamping rod 4 to rotate around the connecting seat 6 (the rotation is flexibly achieved through the shaft and bearing 7).

[0032] The first clamping rod 3 and the second clamping rod 4 have a scissor-like structure, with their upper ends contracting inwards, causing the clamping parts 14 at their ends to close inwards simultaneously, thus gripping the outer wall of the pipe pile from both sides. Since multiple clamping components are distributed along the length of the pipe pile, multi-point clamping is formed, ensuring that the pipe pile is stably fixed in the radial direction.

[0033] During the hoisting process, the pipe pile remains stable under the combined action of the clamping force of the clamping part 14 and the axial limiting of the positioning seat 11, preventing shaking or slippage. After the pipe pile is hoisted to the designated position, the hoisting device is slowly lowered to allow the pipe pile to land.

[0034] When the pipe pile contacts the ground and bears its weight, the load on the lifting device decreases. At this time, the first clamping rod 3 and the second clamping rod 4 open outward again under the action of their own weight and structural characteristics, and the clamping part 14 is separated from the outer wall of the pipe pile.

[0035] The operator loosens nut 12 and pulls the insertion part 13 of positioning seat 11 out from the end of the pipe pile, then the lifting tool can be removed, completing one work cycle.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
