[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model achieves stable fixation of the steel column by setting up a steel column fixing mechanism. During the steel column's ascent, rotating the handle drives the rotating rod to rotate, which in turn causes bevel gear one and bevel gear three to drive the double-acting screw two and double-acting screw one to rotate respectively. The fixing seat threaded onto the double-acting screw moves relative to each other, and the arc-shaped groove on the side of the fixing seat tightly clamps the steel column, effectively preventing the steel column from swaying or shifting during hoisting, ensuring the stability of the hoisting process, and improving the safety and reliability of construction.

[0013] 2. This utility model achieves automation and convenience in the hoisting process by setting up a hoisting mechanism. The motor drives the rotating shaft one to rotate, and through the synchronous belt transmission between synchronous pulley one and synchronous pulley two, the rotating shaft two rotates, which in turn drives the winding roller to wind up the sling, thus realizing the hoisting of the steel column. This hoisting method does not require complicated slings and lifting tools, and the operation is simple and quick, which greatly improves the hoisting efficiency and saves construction time and labor costs. At the same time, the setting of triangular fixing rope and limit plate further improves the stability and safety of the hoisting process, effectively preventing the sling from loosening or falling off during the winding process, and ensuring the stable progress of the hoisting process.

[0019] 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 protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1-4The present invention provides the following technical solution: a large steel column installation auxiliary hanger structure, including a top frame 1, an ear plate 4 is provided at the side corner of the top frame 1, an installation hole 3 is provided inside the ear plate 4, two sets of fixing frames 5 are provided below the top frame 1, the two sets of fixing frames 5 are fixedly connected by a connecting plate 6, a steel column fixing mechanism 7 is provided inside the fixing frame 5, and a hoisting mechanism 2 is provided inside the top frame 1.

[0022] Specifically, the steel column fixing mechanism 7 includes a transmission assembly 71, a mounting box 72, a second double-acting screw 73, an arc-shaped groove 74, a fixing seat 75, and a first double-acting screw 76. The mounting box 72 is located at the upper end of the fixing frame 5, and the transmission assembly 71 is housed inside the mounting box 72. A first double-acting screw 76 is located on one side of the lower end of the mounting box 72 inside the fixing frame 5, and a second double-acting screw 73 is located on the other side of the lower end of the mounting box 72 inside the fixing frame 5. The fixing seat 75 is threaded to both ends of the second double-acting screw 73 and the first double-acting screw 76. Three sets of arc-shaped grooves 74 are provided on the side of the fixing seat 75.

[0023] By adopting the above technical solution, the steel column is stably fixed. During the upward movement of the steel column, the rotating handle 712 is turned to drive the rotating rod 716 to rotate, which in turn causes the bevel gear 1 711 and bevel gear 3 715 to drive the double-acting screw 2 73 and double-acting screw 1 76 to rotate respectively. The fixing seat 75, which is threaded onto the double-acting screw, moves relative to the steel column. The arc groove 74 on the side of the fixing seat 75 tightly clamps the steel column, effectively preventing the steel column from shaking or shifting during hoisting, ensuring the stability of the hoisting process, and improving the safety and reliability of construction.

[0024] Specifically, the transmission assembly 71 includes a first bevel gear 711, a throttle 712, a second bevel gear 713, a fourth bevel gear 714, a third bevel gear 715, and a rotating rod 716. The rotating rod 716 is rotatably connected inside the mounting box 72, and the throttle 712 is located at the other end of the rotating rod 716. The upper end of the second bidirectional lead screw 73 is located inside the mounting box 72 and houses the second bevel gear 713. The upper end of the first bidirectional lead screw 76 is located inside the mounting box 72 and houses the fourth bevel gear 714. The surface of the rotating rod 716 is provided with a third bevel gear 715 that meshes with the fourth bevel gear 714, and the surface of the rotating rod 716 is provided with a first bevel gear 711 that meshes with the second bevel gear 713.

[0025] By adopting the above technical solution, a simple and efficient transmission method is provided. The throttle 712 is designed for easy manual control by the operator. Through the meshing transmission between bevel gears, the rotation of the rotating rod 716 can be converted into the rotation of the bidirectional lead screw, thereby realizing the movement of the fixed seat 75. The operation is simple, the transmission is stable and reliable, and the fixing or loosening of the steel column can be completed quickly, thus improving construction efficiency.

[0026] Specifically, the lower ends of both the second double-acting lead screw 73 and the first double-acting lead screw 76 are rotatably connected to the fixed frame 5 via bearings.

[0027] By adopting the above technical solution, the smooth rotation of the bidirectional lead screw is ensured. The use of bearings reduces the friction between the bidirectional lead screw and the fixed frame 5, allowing the bidirectional lead screw to rotate more flexibly, improving transmission efficiency, and also extending the service life of the bidirectional lead screw and the fixed frame 5, thereby reducing the maintenance cost of the equipment.

[0028] In this embodiment, the steel column is first placed between two sets of fixing frames 5. By rotating the throttle 712, the two-way lead screw 73 and the two-way lead screw 76 are rotated, which drives the fixing seat 75 to move towards the middle. The arc groove 74 tightly clamps the steel column, thus fixing the steel column. Then, the steel column is lifted by the hoisting mechanism 2 for subsequent installation work. During the entire hoisting process, the steel column fixing mechanism 7 can effectively ensure the stability of the steel column, avoid swaying or displacement, and ensure the safety and smooth progress of construction.

[0029] Example 2:

[0030] The difference between this embodiment and Embodiment 1 is that the hoisting mechanism 2 includes a hoisting cable 22, a motor 23, a first rotating shaft 24, a first synchronous pulley 25, a synchronous belt 26, a second rotating shaft 27, a second synchronous pulley 28, and a take-up roller 29. The second rotating shaft 27 is rotatably connected inside the top frame 1. The take-up roller 29 is provided on both ends of the second rotating shaft 27. The hoisting cable 22 is wound around the surface of the take-up roller 29. The lower end of the hoisting cable 22 is fixed to the upper end of the connecting plate 6. The motor 23 is provided on the lower side of the top frame 1. The first rotating shaft 24 is provided at the output end of the motor 23. The first synchronous pulley 25 is provided on the surface of the first rotating shaft 24. The second synchronous pulley 28 is provided on one end of the second rotating shaft 27. The outer surfaces of the first synchronous pulley 25 and the second synchronous pulley 28 are meshed with the synchronous belt 26.

[0031] By adopting the above technical solution, the hoisting process is automated and convenient. The motor 23 drives the rotating shaft 24 to rotate, and through the synchronous belt 26 between the synchronous pulley 25 and the synchronous pulley 28, the rotating shaft 27 rotates, which in turn drives the winding roller 29 to wind up the sling 22, thereby realizing the hoisting of the steel column. This hoisting method does not require the use of complex slings 22 and lifting tools, and the operation is simple and quick, which greatly improves the hoisting efficiency and saves construction time and labor costs.

[0032] Specifically, the hoisting mechanism 2 also includes a triangular fixing rope 21 and a limiting plate 210. The lower end of the sling 22 is provided with a triangular fixing rope 21 at the connection point with the connecting plate 6. The upper center of the top frame 1 is provided with a limiting plate 210. The limiting plate 210 has a through hole corresponding to the second rotating shaft 27.

[0033] By adopting the above technical solutions, the stability and safety of the hoisting process are further improved. The setting of the triangular fixing rope 21 can effectively prevent the sling 22 from loosening or falling off during the winding process, ensuring the stable progress of the hoisting process. The setting of the limit plate 210 can limit the position of the rotating shaft 27, preventing it from shifting or shaking during rotation, improving the operational stability of the equipment and reducing the safety risks caused by equipment failure.

[0034] In this embodiment, the steel column is fixed to the steel column fixing mechanism 7 inside the fixing frame 5. Then, the motor 23 is started, and the motor 23 drives the rotating shaft 24 to rotate. Through the synchronous belt 26 between the synchronous pulley 25 and the synchronous pulley 28, the rotating shaft 27 rotates, which in turn drives the winding roller 29 to wind up the sling 22 and lift the steel column. During the lifting process, the triangular fixing rope 21 and the limiting plate 210 play the roles of fixing and limiting, respectively, to ensure the stability and safety of the lifting process. When the steel column reaches the predetermined position, the motor 23 is turned off and the steel column fixing mechanism 7 is released, and the steel column can be installed in place. The entire lifting process is highly automated, simple and quick to operate, and greatly improves the installation efficiency and safety of large steel columns.

[0035] The working principle and usage process of this utility model are as follows: When using this utility model, firstly, the steel column is placed between two sets of fixing frames 5. By rotating the handle 712, the two-way lead screw 73 and the two-way lead screw 76 rotate, causing the fixing seat 75 to move towards the center. The arc-shaped groove 74 tightly clamps the steel column, completing the fixing of the steel column. Then, the steel column is lifted by the hoisting mechanism 2 for subsequent installation work. Throughout the hoisting process, the steel column fixing mechanism 7 effectively ensures the stability of the steel column, preventing swaying or displacement, ensuring the safety and smooth progress of construction. The steel column is fixed to the steel column fixing mechanism 7 inside the fixing frame 5. Then, the motor 23 is started, which drives the rotating shaft 24 to rotate. Through the synchronous belt 26 between the synchronous pulley 25 and the synchronous pulley 28, the rotating shaft 27 rotates, which in turn drives the winding roller 29 to wind up the sling 22 and lift the steel column. During the lifting process, the triangular fixing rope 21 and the limiting plate 210 play the roles of fixing and limiting, respectively, to ensure the stability and safety of the lifting process. When the steel column reaches the predetermined position, the motor 23 is turned off and the steel column fixing mechanism 7 is released, and the steel column can be installed in place. The whole lifting process is highly automated, simple and quick to operate, and greatly improves the installation efficiency and safety of large steel columns.
