[0002] Structures made mainly of steel are one of the main types of building structures, and the characteristics of steel are high strength, light weight, good overall rigidity, and strong deformation capacity, so it is particularly suitable for building large-span and super-high and super-heavy buildings.

[0003] Steel structures usually need to be hoisted when in use. For example, the utility model patent with the announcement number CN218950776U provides an adjustable hoisting device for a steel structure. Although the device can hoist the steel structure, it cannot effectively control the swing amplitude of the steel structure during hoisting. The steel structure swings greatly during hoisting, which not only increases the difficulty of hoisting, but also may affect the stability of the hoisting process and even cause potential safety hazards.

[0004] Therefore, effective measures must be taken to control the swing of the steel structure to ensure the smooth progress of the hoisting work and the stability and safety of the structure. Therefore, there is an urgent need to design an adjustable hoisting device for a steel structure. SUMMARY

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0020] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0021] The present application will be further described below with reference to the drawings and specific embodiments, but is not limited by the embodiments.

[0022] As shown in the drawings, Figures 2 to 6 the adjustable hoisting device for steel structure provided in the embodiment of the present application comprises a clamp 5, a control component and a stabilizing component; the control component is used for controlling the swing of the steel structure during hoisting and pumping air flow outwards under the action of the swing of the steel structure; the stabilizing component is used for receiving the air flow and selectively spraying air to the direction in which the steel structure is inclined, so as to reduce the swing of the steel structure and realize automatic stabilization of the steel structure; the clamp 5 is installed at the bottom of the stabilizing component.

[0023] As a specific example, Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the above-mentioned stabilizing assembly comprises a gas guide ring 8, a communication pipe 9, a jet pipe 10 and a piston disc 22, the gas guide ring 8 has an annular inner cavity 24, the communication pipe 9 is installed on the gas guide ring 8 along the annular direction, the communication pipe 9 is communicated with the gas guide ring 8, and two communication holes are formed on the side wall of the end of the communication pipe 9 close to the gas guide ring 8, the jet pipe 10 is installed on the communication pipe 9 through the communication holes, and the piston disc 22 is slidably installed in the communication pipe 9. Figure 5 and Figure 6 As shown, if the gas guide ring 8 is left low and right high under the skew phenomenon, the piston disc 22 in the right part of the communication pipe 9 is blocked due to the downward sliding, and the airflow cannot be sprayed from the corresponding jet pipe 10; and the piston disc 22 in the left part of the communication pipe 9 is completely released due to the downward sliding, and the airflow is sprayed through the gas guide ring 8, the communication pipe 9 and the jet pipe 10, thereby forming a reaction force to reduce the swing amplitude of the steel structure and the like, ensuring the stability and safety during lifting, and further improving the use effect of the device. It should be noted that based on the above-mentioned swing reduction principle, the outlet direction and angle of the jet pipe 10 can be adjusted as needed by those skilled in the art.

[0024] Further, in order to more flexibly control the piston disc 22, especially the initial position of the piston disc 22, the piston disc 22 can be fixed on the gas guide ring 8 by means of the first spring rod 21 in the present application. Specifically, the fixed end of the first spring rod 21 is installed on the inner wall of the gas guide ring 8, the piston disc 22 is installed on the telescopic end of the first spring rod 21, the piston disc 22 blocks the communication hole at the initial position, the piston disc 22 pulls the spring in the first spring rod 21 when it slides downward, and the piston disc 22 resets and blocks the communication hole under the action of the spring when the clamp 5 is horizontal.

[0025] As a specific example, the control assembly comprises a hollow box 3, a damping ball 13 installed in the hollow box 3, the damping ball 13 is installed in the hollow box 3 through a connecting rope 15, the clamp 5 is installed at the bottom of the hollow box 3 through the bottom plate 2, and the gas guide ring 8 is installed on the periphery of the bottom of the hollow box 3 on the bottom plate 2; under the above-mentioned structure, the damping ball 13 can be used to reduce the swing and achieve balance when the clamp 5 swings.

[0026] Further, in order to pump the airflow by means of the swing of the steel structure, as shown in Figure 2 , Figure 3As shown in the figure, the control assembly in the present application also includes a gas tank 4, a piston plate 11 and a transmission component. The upper part of the gas tank 4 is in one-way communication with the atmosphere (a gas inlet pipe 6 is installed on the upper part of the gas tank 4, and a first one-way valve is installed in the gas inlet pipe 6), the hollow tank 3 is installed at the bottom of the gas tank 4, the gas guide ring 8 is in one-way communication with the upper part of the gas tank 4 through a gas outlet pipe 7 (a second one-way valve is installed in the gas outlet pipe 7), the piston plate 11 is slidably installed in the gas tank 4, and the transmission component in the present application can push the piston plate 11 upward under the swing action of the damping ball 13 to pump the gas flow into the gas guide ring 8 through the gas tank 4.

[0027] As a specific example, as shown in the figure, Figure 2 , Figure 3 , Figure 4 The transmission component includes a second spring rod 14, two sleeve plates 17, two rotating discs 16, two racks 19, two movable rods 18 and two vertical rods 12. The two sleeve plates 17 and the fixed end of the second spring rod 14 are installed on the hollow tank 3 (the sleeve plates 17 are located on both sides of the second spring rod 14), the rotating disc 16 is rotatably installed on the sleeve plate 17, the rack 19 is installed on the telescopic end of the second spring rod 14 through a fixed plate 23, the rack 19 is in meshing connection with the gear 20 on the rotating disc 16, the bottom of the movable rod 18 is rotatably installed on the rotating disc 16, the top of the movable rod 18 is rotatably installed on the bottom of the vertical rod 12, the top of the vertical rod 12 is installed on the piston plate 11, and the connecting rope 15 is installed on the telescopic end of the second spring rod 14. Under the above structure, when the clamp 5 is tilted, the damping ball 13 swings, when the damping ball 13 swings upward, the pulling force of the damping ball 13 on the telescopic end of the second spring rod 14 decreases, the telescopic end of the second spring rod 14 slides upward in the second spring rod 14 under the spring action, thereby driving the rack 19, the rack 19 drives the gear 20 to rotate, thereby pushing the piston plate 11 upward through the movable rod 18 and the vertical rod 12, and the gas in the gas tank 4 is pumped into the gas guide ring 8 through the gas outlet pipe 7 under the action of the piston plate 11, and then sprayed out through the gas jet pipe 10, thereby forming a reaction force to reduce the swing amplitude of the steel structure and other components; conversely, when the damping ball 13 swings downward, the telescopic end is pulled downward by the damping ball 13, the piston plate 11 moves downward, and the gas in the atmosphere is sucked into the gas tank 4 through the gas inlet pipe 6.

[0028] As shown in the figure, Figure 1 The hoisting device can be installed on a carrier, such as a gantry 1 with a winch (the hoisting device is installed at the end of the winch), to realize the hoisting of the steel structure.
