Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to an auxiliary hoisting device for prefabricated wall panels. Background Technology

[0002] Prefabricated modular construction represents the mainstream development direction of green, environmentally friendly, and emission-reduction technologies in the construction industry, facilitating the modularization, industrialization, and standardization of building components. Prefabricated wall panels are widely used in concrete, light steel, and composite structure buildings, and have become an important component of prefabricated construction. Prefabricated wall panels are manufactured in standardized processes at prefabrication plants, then transported to the construction site for convenient, integrated installation.

[0003] In related technologies, please refer to Chinese Patent No. CN217838049U, which specifically discloses a hoisting device for prefabricated components. When using this hoisting device, the lifting and lowering adjustment of the limiting slide plate is easily controlled via a telescopic component. When the limiting slide plate moves downwards, it provides auxiliary limiting for the hanging rings on the two sets of traction steel wires, maintaining the stability of the distance between the two sets of hanging rings. After the prefabricated component is hoisted onto the hanging rings, it effectively prevents relative rotation or swaying of the traction steel wires on the support frame, maintaining the stability of the prefabricated component after hoisting.

[0004] The applicant found a deficiency in the use of the aforementioned hoisting device for prefabricated components: Although the prior art can provide auxiliary limiting for the traction wires, better ensure the stability between the traction wires, and effectively prevent the traction wires from rotating or swaying relative to each other on the support frame, thus maintaining the stability of the prefabricated components after hoisting.

[0005] However, there are still shortcomings in actual use: for example, the spacing between the traction steel wires is relatively fixed, which makes it difficult to lift prefabricated components of various widths or lengths, thus reducing practicality.

[0006] In view of this, this technical solution proposes an auxiliary hoisting device for prefabricated wall panels, which can better solve the problems mentioned above.

[0007] Utility model content.

[0008] The technical solution adopted by this utility model is as follows: a precast wall panel auxiliary hoisting device, including a hoisting rod, a hanging ring fixed at the top of the hoisting rod, a sliding groove opened inside the hoisting rod, and a double-acting screw rotatably installed inside the sliding groove, with sliders inserted into both sides of the sliding groove, and the sliders threadedly connected to the double-acting screw, a movable frame provided on the hoisting rod, and the movable frame fixedly connected to the sliders, and the bottom of the movable frame connected to a wall panel hoisting mechanism for clamping and hoisting precast components via a first steel wire rope;

[0009] The bottom of the lifting rod is fixed with threaded rods at both the front and rear, and anti-sway plates are fitted on the threaded rods. Nuts are threaded onto the threaded rods and abut against the upper and lower surfaces of the anti-sway plates.

[0010] The anti-sway plate has a moving groove and a limiting groove inside. A moving seat is inserted into the moving groove and is sleeved on the first steel wire rope. Each side of the moving seat is fixed with a limiting plate inserted into the limiting groove. The outer side of the limiting plate is threaded with a positioning bolt for positioning the moving seat and the limiting plate by abutting against the side of the anti-sway plate.

[0011] In a preferred embodiment, the hanging ring is fixed at the top center of the lifting rod, and the hanging ring is connected and used in conjunction with external lifting equipment.

[0012] In a preferred embodiment, the front end of the bidirectional lead screw is disposed on the outside of the lifting rod, and a handle for rotating the bidirectional lead screw is fixed to the outer end of the bidirectional lead screw.

[0013] In a preferred embodiment, the movable frame has a U-shaped structure, and a positioning bolt is threadedly connected to the upper sides of both sides of the movable frame. The positioning bolt abuts against the side of the lifting rod, and an operating plate for rotating the positioning bolt is provided on the bolt head.

[0014] In a preferred embodiment, the wall panel hanging mechanism comprises a left-rotating hanger, a right-rotating hanger, a second steel wire rope, a clamping plate, an anti-slip pad, and a return spring. The left-rotating hanger and the right-rotating hanger are rotatably installed, and a second steel wire rope connected to the first steel wire rope is fixed between the upper parts of the left-rotating hanger and the right-rotating hanger. A clamping plate is rotatably installed at a relative position below the right-rotating hanger and the left-rotating hanger, and a return spring is provided between the clamping plate and the left-rotating hanger and the right-rotating hanger.

[0015] In a preferred embodiment, a set of clamping plates are provided with anti-slip pads on opposite surfaces, and the anti-slip pads are anti-slip silicone pads.

[0016] In a preferred embodiment, the moving groove and the limiting groove are connected, and a through hole is provided in the middle of the moving seat, and the first steel wire rope is inserted into the through hole.

[0017] In a preferred embodiment, the bolt head diameter of the second positioning bolt is greater than the width of the limiting groove, and an operating plate for rotating the second positioning bolt is fixed to the bolt head of the second positioning bolt.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: this technical solution can be used to lift prefabricated components of various widths or lengths, and can ensure the stability of the prefabricated components during lifting.

[0019] 1. In this utility model, by rotating the handle, the handle drives the bidirectional lead screw to rotate. At this time, the bidirectional lead screw drives a set of sliders and moving frame to move in position. Since the bidirectional lead screw is a bidirectional lead screw, the distance between the first wire rope and the wall panel lifting mechanism can be adjusted to the distance for lifting the precast wall panel. At this time, the positioning bolt is locked and abutted against the side of the lifting rod, and then the wall panel lifting mechanism is clamped on the precast wall panel.

[0020] 2. In this utility model, the anti-sway plate is moved to the lower part of a set of first steel wire ropes by using a nut, and then the position of the moving seat and the limiting plate is positioned by abutting the second positioning bolt against the side of the anti-sway plate, thereby limiting the spacing between the set of first steel wire ropes and increasing the stability of the set of first steel wire ropes during use.
