Description

Technical Field

[0001] This utility model relates to the field of pipe pile production technology, specifically to a lifting hook used in the production of pipe piles. Background Technology

[0002] Pipe piles are hollow, ring-shaped piles, resembling giant "cement pipes." They are driven into the ground by forceful impact or pressing to serve as the foundation of buildings, transferring the load of the superstructure to deep, solid soil or rock layers.

[0003] Currently, hooks are generally used for lifting pipe piles during production and transportation. However, the current hooks have simple structures and no fixed effect on the pipe piles. Before the steel wire rope connected to the hook is tightened, the hook is prone to falling out of the openings at both ends of the pipe pile, requiring multiple reassemblies. Furthermore, the connection stability with the pipe pile is poor. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a hook for producing pipe piles, which can be positioned with the pipe pile and tightened together, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a hook for producing pipe piles, comprising a hook body inserted into the openings at both ends of the pipe pile, one end of the hook body being cylindrical, and an installation groove being provided on the end of the hook body inside the pipe pile, with multiple positioning holes on the inner surface of the installation groove, and a clamping plate being provided in each positioning hole, one side of the clamping plate being in contact with the inner wall of the pipe pile, and the other side being provided with an inclined guide portion, the inside of the installation groove being provided with an extrusion block that inwardly presses the clamping plate and abuts against the guide portion, one end of the clamping plate being provided with a limiting groove, and one end of the hook body being threadedly connected to a limiting ring, one end of which is inserted into the limiting groove of the multiple clamping plates.

[0006] As a preferred technical solution, a fixing hole is provided on the exposed end of the hook body, and a connecting lug is installed on the opposite side of the hook body. A wire rope is provided between the connecting lugs, and a safety hook is installed at both ends of the wire rope. The safety hooks are all sleeved on the connecting lugs.

[0007] As a preferred technical solution, the inner wall of the mounting groove is provided with an axial clearance groove, and the inner wall of the clearance groove is provided with an axial shaft hole communicating with the outside. An electric push rod is installed on the outside of the hook body. The piston rod of the electric push rod extends into the mounting groove through the shaft hole and the clearance groove, and is fixedly connected to the extrusion block.

[0008] As a preferred technical solution, the extrusion blocks are all arranged in a conical structure.

[0009] As a preferred technical solution, the width of the limiting groove is greater than the thickness of the outer wall of the limiting ring, and the outer ring surface of the limiting ring protrudes to form an anti-slip part.

[0010] As a preferred technical solution, the hook body is designed with an "L" shape.

[0011] As a preferred technical solution, the inner side of the positioning port is configured to contact the outer side of the clamping plate.

[0012] As a preferred technical solution, the inner diameter of the clearance groove is larger than the diameter of the extrusion block.

[0013] The beneficial effects of this utility model are as follows: This utility model has a simple structure. The hook body can be inserted into the openings at both ends of the pipe pile, and the clamping plate can be pushed outward by the movement of the squeezing block. The squeezing force between the clamping plate and the pipe pile body can fix the hook body on the pipe pile, preventing it from falling. The two hook bodies can be connected together by a steel wire rope, preventing the hook bodies from opening outwards to each other, thus ensuring safety during the hoisting process. The limiting ring can limit the clamping plate, preventing it from falling out and facilitating replacement. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0022] 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.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a hook for producing pipe piles, comprising a hook body 2 inserted into the openings at both ends of a pipe pile 1. One end of the hook body 2 is cylindrical. The end of the hook body 2 inside the pipe pile 1 is provided with an installation groove 10. The inner surface of the installation groove 10 is provided with multiple positioning holes. Each positioning hole is provided with a clamping plate 7. One side of the clamping plate 7 is in contact with the inner wall of the pipe pile 1, and the other side is provided with an inclined guide portion 13. Inside the installation groove 10, there is a pressing block 12 that presses the clamping plate 7 inward and abuts against the guide portion 13. One end of the clamping plate 7 is provided with a limiting groove 14. One end of the hook body 2 is threadedly connected to a limiting ring 9. One end of the limiting ring 9 is inserted into the limiting groove 14 of the multiple clamping plates 7.

[0024] In this embodiment, a fixing hole 5 is provided on the exposed end of the hook body 2, and a connecting lug 8 is installed on the opposite side of the hook body 2. A wire rope 3 is provided between the connecting lugs 8, and a safety hook 4 is installed at both ends of the wire rope 3. The safety hook 4 is sleeved on the connecting lug 8.

[0025] In this embodiment, the inner wall of the mounting groove 10 is provided with an axial clearance groove 11, and the inner wall of the clearance groove 11 is provided with an axial shaft hole communicating with the outside. The hook body 2 is equipped with an electric push rod 6 on the outside. The piston rod of the electric push rod 6 extends through the shaft hole and the clearance groove 11 into the mounting groove 10 and is fixedly connected to the extrusion block 12.

[0026] In this embodiment, the extrusion blocks 12 are all arranged in a conical structure, so that the extrusion blocks can fully contact the guide portion on the clamping plate and push the clamping plate outward.

[0027] In this embodiment, the width of the limiting groove 14 is greater than the thickness of the outer wall of the limiting ring 9, and an anti-slip part is formed by protrusion on the outer ring surface of the limiting ring 9.

[0028] The limiting ring restricts the movement distance of the clamping plate, allowing it to move only between the limiting groove and the limiting ring, thus preventing the lower clamping plate from falling out of the positioning hole.

[0029] Furthermore, after the limiting ring is removed from the limiting groove, the clamping plate can be taken out along the positioning port, making it easy to replace and adapt to different situations.

[0030] In this embodiment, the hook body 2 is designed in an "L" shape, so that one end of the hook body can be smoothly inserted laterally into the opening of the pipe pile.

[0031] In this embodiment, the inner side of the positioning port is in contact with the outer side of the clamping plate 7, which increases the positioning effect and makes the clamping plate move only along the inside and outside of the positioning port.

[0032] In this embodiment, the inner diameter of the clearance groove 11 is larger than the diameter of the extrusion block 12; wherein, after the electric push rod retracts, the extrusion block can enter the clearance groove, so that the clamping plate can move inward sufficiently to reduce the diameter, thereby being able to be inserted into pipe piles with different inner diameters, increasing adaptability.

[0033] Working principle: First, insert the hook body into the openings at both ends of the pipe pile, then start the electric push rod to extend the piston rod of the electric push rod. The movement of the piston rod drives the extrusion block. Through the extrusion block extruding the guide part, the clamping plate can move outward synchronously along the positioning port until it contacts the inner wall of the pipe pile, thereby fixing the hook body to the pipe pile body and greatly reducing the probability of falling out.

[0034] After the hook body is installed, the safety hooks at both ends of the wire rope can be hooked onto the connecting lugs. The wire rope can pull the hook body inward and prevent it from opening outward during hoisting, thus increasing safety.

[0035] 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.
