Description

Technical Field

[0001] This utility model belongs to the field of building construction hoisting technology, and in particular relates to a hoisting device for prefabricated building walls. Background Technology

[0002] In the field of prefabricated buildings, the installation of prefabricated walls is a crucial step. Traditional methods for hoisting prefabricated walls mainly rely on tower cranes for direct hoisting and adjustment. While this method is direct, it has many shortcomings.

[0003] First, the tower crane needs to be operated precisely when adjusting the position of the precast wall, which takes a long time and affects the hoisting efficiency.

[0004] Secondly, tower cranes need to be continuously occupied during the hoisting process, making it impossible to carry out other hoisting tasks at the same time, resulting in low utilization efficiency of the tower cranes on site.

[0005] In addition, traditional hoisting devices have certain limitations in terms of structural stability, positioning accuracy, and ease of operation, making it difficult to meet the requirements of efficient, safe, and precise construction of modern prefabricated buildings.

[0006] Therefore, it is necessary to develop a new type of prefabricated building wall hoisting device.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0008] The purpose of this utility model is to provide a prefabricated building wall hoisting device. By setting self-locking small wheels and reinforcing structures on the support hoisting frame, and cooperating with electric hoists and wired controllers, the device enables precise hoisting and flexible adjustment of the wall. This solves the problems of long adjustment time, poor structural stability, inaccurate positioning and inconvenient operation of tower cranes in the prior art, improves hoisting efficiency and safety, and meets the needs of efficient construction of modern prefabricated buildings.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a prefabricated building wall hoisting device, comprising a support hoisting frame, a wall hoisting frame, an electric hoist, and a wired controller; the electric hoist is installed in the middle of the support hoisting frame; the wall hoisting frame is vertically guided to the support hoisting frame, and the wall hoisting frame is hung on the wire rope hook of the electric hoist; the wired controller is placed on one of the support legs of the support hoisting frame; two slings are symmetrically installed on the wall hoisting frame.

[0010] As a preferred embodiment of this utility model, the supporting hoisting frame includes a supporting crossbeam; the electric hoist is installed in the middle of the supporting crossbeam; a pair of horizontal longitudinal bars are fixed near both ends of the supporting crossbeam; a supporting leg is fixed to the end of each horizontal longitudinal bar; and two lifting rings are symmetrically fixed to the upper end of the supporting crossbeam.

[0011] As a preferred embodiment of this utility model, a reinforcing beam is provided between the supporting crossbeam and the adjacent side wall of the horizontal longitudinal bar; a reinforcing plate is provided between the horizontal longitudinal bar and the supporting leg.

[0012] As a preferred embodiment of this utility model, a horizontally arranged flange plate is fixed to the lower end of the support leg; a small wheel with self-locking is installed below the flange plate.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1: Please see Figure 1-4 As shown, this utility model is a prefabricated building wall hoisting device, including a support hoisting frame 1, a wall hoisting frame 2, an electric hoist 3, and a wired controller 4. The electric hoist 3 is installed in the middle of the support hoisting frame 1. The wall hoisting frame 2 is vertically guided to the support hoisting frame 1, and the wall hoisting frame 2 is hung on the wire rope hook of the electric hoist 3. The wired controller 4 is placed on one of the support legs 13 of the support hoisting frame 1. Two slings 5 ​​are symmetrically installed on the wall hoisting frame 2.

[0028] The supporting hoisting frame 1 includes a supporting crossbeam 11. An electric hoist 3 is installed in the middle of the supporting crossbeam 11. A pair of horizontal longitudinal bars 12 are fixed near both ends of the supporting crossbeam 11. A supporting leg 13 is fixed to the end of each horizontal longitudinal bar 12. Two lifting rings 14 are symmetrically fixed to the upper surface of the supporting crossbeam 11.

[0029] A reinforcing beam 15 is provided between the adjacent side walls of the supporting beam 11 and the horizontal longitudinal bar 12. A reinforcing plate 16 is provided between the horizontal longitudinal bar 12 and the supporting leg 13.

[0030] The lower end of the support leg 13 is fixed with a horizontally arranged flange plate 17. A self-locking wheel (not shown in the figure) is installed below the flange plate 17. Installing the self-locking wheel further reduces the tower crane's lifting and adjustment time. Without the wheel, the tower crane needs to adjust the support lifting frame 1, the wall lifting frame 2, and the prefabricated wall being lifted onto them to the accurate installation position. With the wheel installed, the tower crane only needs to place the support lifting frame 1, the wall lifting frame 2, and the prefabricated wall being lifted onto them near the installation position. After the support lifting frame 1 lands, it can detach from the tower crane and the two lifting rings 14 on the support lifting frame 1, allowing the tower crane to perform other tasks, freeing up its carrying capacity and improving the efficiency of the tower crane on site.

[0031] The wall-mounting frame 2 includes a hoisting beam 21. A pair of upward-facing rectangular guide rods 22 are fixed to the opposite side walls at both ends of the hoisting beam 21. The inner side walls of the pair of rectangular guide rods 22 are linearly guided to the outer side walls of the supporting beam 11. The inner side walls of the pair of rectangular guide rods 22 are linearly guided to the outer side walls of the horizontal longitudinal bar 12. An upward-facing column rod 23 is fixed to the middle of the upper surface of the hoisting beam 21. Diagonal tie rods 24 are symmetrically arranged on both sides of the upper end of the column rod 23 between it and the upper surface of the hoisting beam 21. A lifting hole 25 is provided at the connection between the column rod 23 and the two diagonal tie rods 24, which engages with the wire rope hook of the electric hoist 3. A rectangular upright plate 26 is fixed to the lower end of the hoisting beam 21. Two sets of symmetrically arranged sling mounting holes 27 are provided on the rectangular upright plate 26.

[0032] One of the support legs 13 is equipped with a battery box 6. A portable power supply 7 is installed inside the battery box 6. A wired controller 4, the portable power supply 7, and the electric hoist 3 are electrically connected. The wired controller 4 controls the electric hoist 3 to raise and lower the wire rope, thus enabling the adjustment of the wall hoisting frame 2 relative to the supporting hoisting frame 1. Power is drawn from the site when the portable power supply 7 is unavailable. The optimal configuration for this prefabricated building wall hoisting device is with the portable power supply 7 installed. The wired controller 4 is installed on one side of the battery box 6. A pressure plate is also screwed onto the upper part of the battery box 6. After the portable power supply 7 is placed inside the battery box 6, the pressure plate is installed to prevent it from sliding out.

[0033] One specific application of this embodiment is: The process of ground-mounted precast interior wall: The vehicle brings the precast wall to the site, and the prefabricated building wall hoisting device is moved to be installed above the precast interior wall to be suspended. The wired controller 4 is used to control the electric hoist 3 to release the wire rope, the wall hoisting frame 2 is lowered, and the two slings 5 ​​are installed on two nearly symmetrical steel bar hanging rings at the upper end of the precast interior wall. The wired controller 4 is operated again to control the electric hoist 3 to retract the wire rope, the wall hoisting frame 2 is raised, and the precast interior wall is lifted, waiting for the tower crane to lift.

[0034] The process of adjusting the precast interior wall on the roof: The tower crane lifts the entire hoisting device, along with the precast interior wall, and transfers it to the rooftop, spanning the installation position. After the four small wheels touch the ground, they detach from the tower crane and the two lifting rings 14 on the support hoisting frame 1, allowing the tower crane to be used for other hoisting work. Move the support hoisting frame 1 to the accurate installation position of the precast interior wall, lock the four small wheels, and use the wired controller 4 to control the electric hoist 3 to release the wire rope. The wall hoisting frame 2 is lowered. After the precast interior wall is installed in place, install the positioning support reinforcement frame between the precast wall and the rooftop. After the reinforcement frame is installed, continue to use the wired controller 4 to control the electric hoist 3 to release the wire rope, so that the two slings 5 ​​can be detached from the upper steel bar hanging rings of the precast interior wall.
