Description

Technical Field

[0001] This utility model relates to the field of vertical shaft interlocking pile construction technology, specifically to a steel hoisting device for vertical shaft steel-concrete interlocking piles. Background Technology

[0002] Interlocking piles are a type of foundation pit retaining structure in which piles interlock with each other. The piles are arranged alternately with one unreinforced plain concrete pile (Pile A) and one steel-concrete composite pile (Pile B, using H-shaped steel sections instead of a reinforcing cage). During construction, piles A are constructed first, followed by piles B. Pile B is constructed before the initial setting of the concrete in piles A. The concrete at the intersection of adjacent piles A is then cut away, thus achieving the interlocking effect.

[0003] When constructing pile B, H-beams need to be vertically hoisted and placed into the pile hole. A common method for hoisting H-beams is to weld lifting lugs onto the beam. For example, utility model patent CN218507384U discloses a simple H-beam hoisting tool, including a pair of wing plates and a web plate located between the wing plates. This hoisting tool includes a triangular plate with a top and a bottom. The top includes a hoisting hole for engaging with a lifting component. The bottom includes a T-shaped slot, which is configured to match the dimensions of the wing plates and part of the web plate, allowing the wing plates to be threaded and secured within the T-shaped slot. The simple H-beam hoisting tool is designed to form an acute angle with the wing plates during hoisting, ensuring that the upper and lower surfaces of the T-shaped slot contact the upper and lower surfaces of the wing plates. This patent allows for horizontal hoisting of the H-beam, but it is difficult to adjust the H-beam to a vertical position for hoisting into the pile hole. Utility Model Content

[0004] The main purpose of this utility model is to provide a steel hoisting device for vertical shaft steel-concrete interlocking piles, which solves the problem of existing steel hoisting devices hoisting steel into the pile hole in a vertical state.

[0008] As a further improvement of this utility model, the first abutting member includes a first abutting sleeve disposed on the side abutting plate and a first abutting rod disposed inside the first abutting sleeve; the two ends of the first abutting rod are respectively connected to the first abutting sleeves on the two sets of side abutting plates by threads of different directions, and a rotating screw head is provided in the middle of the first abutting rod.

[0009] As a further improvement of this utility model, the telescopic component includes a telescopic sleeve and two sets of telescopic rods slidably disposed within both ends of the telescopic sleeve, with the two sets of telescopic rods respectively fixedly connected to two sets of side abutment plates.

[0012] As a further improvement of this utility model, the lifting rope includes a secondary lifting rope connected to the lifting head and a main lifting rope connected to the middle of the secondary lifting rope.

[0013] The beneficial effects of this utility model are reflected in:

[0014] By setting the first abutment member to push the two sets of side abutment plates to abut against the two sets of wing plates, and then using the second abutment member to push the bottom abutment plate to connect with the web plate, the abutment component is connected to the steel section. Then, the lifting equipment drives the lifting rope to move upward, thereby lifting the steel section into a vertical state. During the lifting process, the lifting rod is subjected to a force that pushes the two sets of side abutment plates onto the wing plates, further strengthening the connection stability between the side abutment plates and the wing plates, thus facilitating the vertical installation of the steel section into the pile hole.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] In one embodiment, see Figure 1 The present invention relates to a steel hoisting device for vertical shaft steel-concrete interlocking piles, comprising an abutment component and a hoisting component.

A bottom abutment plate 7 is rotatably disposed on the second abutment member 6. Under external force, the first abutment member 4 drives the side abutment plates 3 to move in opposite directions or towards each other, thereby causing the side abutment plates 3 to abut or separate from the flanges 1 of the steel section; under external force, the second abutment member 6... The bottom abutment plate 7 is moved away from or toward the telescopic member 5, thereby causing the bottom abutment plate 7 to abut or separate from the web plate 2 of the steel section; the lifting assembly includes two sets of lifting rods 8 that are rotatably connected to the two sets of side abutment plates 3 respectively, and a lifting head 9 that is rotatably connected to the lifting rods 8. The lifting head 9 is located below the connection point between the lifting rods 8 and the side abutment plates 3, and a lifting rope 10 is provided on the lifting head 9; the distance between the connection points of the two sets of lifting rods 8 and the lifting head 9 is less than the distance between the connection points of the lifting rods 8 and the two sets of side abutment plates 3.

[0025] Further, see Figure 2 The first abutting member 4 includes a first abutting sleeve 401 disposed on the side abutting plate 3 and a first abutting rod 402 disposed inside the first abutting sleeve 401. The two ends of the first abutting rod 402 are respectively connected to the first abutting sleeves 401 on the two sets of side abutting plates 3 by threads with different directions. The middle part of the first abutting rod 402 is provided with a rotating screw head 403.

[0026] Preferably, two sets of first abutting sleeves 401 are provided, and the two sets of first abutting sleeves 401 are respectively provided with internal threads. The internal threads in the two sets of first abutting sleeves 401 are respectively positive threads and negative threads.

[0027] Preferably, the outer walls at both ends of the first abutment rod 402 are respectively provided with positive thread and negative thread.

[0028] Preferably, the rotating screw head 403 has a regular hexagonal structure.

[0029] In the above configuration, the first abutting rod 402 and the first abutting sleeve 401 are connected by a positive thread and a negative thread, respectively, so that the two sets of first abutting sleeves 401 rotate in opposite directions relative to the first abutting rod 402. When the first abutting rod 402 is rotated counterclockwise, the two sets of first abutting sleeves 401 move towards each other and separate from the wing plate 1. When the first abutting rod 402 is rotated clockwise, the two sets of first abutting sleeves 401 move in opposite directions and abut against the wing plate 1.

[0030] Furthermore, the telescopic component 5 includes a telescopic sleeve 501 and two sets of telescopic rods 502 slidably disposed within both ends of the telescopic sleeve 501. The two sets of telescopic rods 502 are respectively fixedly connected to two sets of side abutment plates 3.

[0031] Preferably, the telescopic sleeve 501 is a rectangular body with open ends and closed middle. A screw hole 11 is provided in the closed middle position of the telescopic sleeve 501, and the second abutment rod 601 is connected to the screw hole 11 by threads.

[0032] Further, see Figure 3 , 4 5. The second abutting member 6 includes a second abutting rod 601 rotatably mounted on the telescopic sleeve 501 and a second abutting sleeve 602 mounted on the bottom surface 7 abutting plate. The second abutting rod 601 and the second abutting sleeve 602 are rotatably connected.

[0033] Preferably, the second abutment sleeve 602 has a rotating cavity 12 inside, and the port of the rotating cavity 12 is provided with a limiting ring 13.

[0034] Preferably, the end of the second abutment rod 601 is provided with a rotating ring 14, which is located in the rotating cavity 12, and the outer diameter of the rotating ring 14 is larger than the inner diameter of the limiting ring 13.

[0035] Preferably, the end of the second abutment rod 601 is provided with a regular hexagonal hole 15.

[0036] In the above configuration, the telescopic rod 502 is connected to two sets of side abutment plates 3, and the second abutment rod 601 is connected to the telescopic sleeve 501 and then to the bottom abutment plate 7, thereby connecting the two sets of side abutment plates 3 and the bottom abutment plate 7. When the first abutment rod 402 rotates and drives the two sets of side abutment plates 3 to move in opposite directions, the two sets of telescopic rods 502 slide within the telescopic sleeve 501. After the two sets of side abutment plates 3 abut against the wing plate 1, the second abutment rod 601 is rotated and pushed away from the telescopic sleeve 501 by the thread, so that the bottom abutment plate 7 abuts against the web plate 2. The two sets of side abutment plates 3 and the bottom abutment plate 7 abut against the steel section, thereby connecting the abutment assembly with the steel section.

[0037] Further, see Figure 2 , 3 The side abutment plate 3 is provided with a first bracket 16, and the first bracket 16 is provided with a first rotating shaft 17; the lifting head 9 is provided with a second bracket 18, and the second bracket 18 is provided with a second rotating shaft 19.

[0039] Preferably, the two sets of lifting rods 8 form a "V" shape.

[0040] Further, see Figure 1The lifting rope 10 includes a secondary lifting rope 1001 connected to the lifting head 9 and a main lifting rope 1002 connected to the middle of the secondary lifting rope 1001.

[0041] Preferably, the two ends of the lifting auxiliary rope 1001 are connected to the center of the two sets of lifting heads 9 on both sides of the web plate 2.

[0042] In the above configuration, when the main lifting rope 1002 moves upward, the auxiliary lifting rope 1001 drives the lifting head 9, lifting rod 8, side abutment plate 3, and bottom abutment plate 7 to move upward together, thereby lifting one end of the steel section and placing the steel section in a vertical state after lifting. Under the action of the weight of the steel section, the force exerted by the auxiliary lifting rope 1001 on the lifting head 9 is vertically upward, and this force is transmitted along the lifting rod 8 to the side abutment plate 3, thereby enhancing the connection stability between the side abutment plate 3 and the wing plate 1.

[0043] In this embodiment, two sets of ground connection components are installed on both sides of the web plate 2 of the steel section. The first abutment rod 402 is rotated to push the side abutment plate 3 to abut against the wing plate 1, and the second abutment rod 601 is rotated to push the bottom abutment plate 7 to abut against the web plate 2, thereby firmly connecting the abutment components to the steel section. The main lifting rope 1002 is connected to the lifting equipment, and the lifting auxiliary rope 1001 is moved upward by the lifting equipment, thereby moving the side abutment plate 3, the bottom abutment plate 7, and the steel section upward, lifting the steel section to a vertical state, so that the steel section can be lifted into the pile hole.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
