Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a high-efficiency hoisting device for reinforcing T-shaped steel in photovoltaic factory buildings. Background Technology

[0002] Against the backdrop of a global push for clean energy development, photovoltaic (PV) power generation, as a sustainable and clean energy source, has been widely applied and promoted. As an important carrier of PV power generation systems, PV factory buildings are seeing an increasing number of construction and renovation projects. Many existing industrial buildings, with their spacious rooftops, have become ideal choices for conversion into PV factory buildings.

[0003] Most existing factory buildings did not adequately consider the subsequent installation of photovoltaic equipment during the initial design, resulting in the original steel structure being unable to meet the new load-bearing requirements. To enhance the load-bearing capacity of the factory's steel structure, adding T-shaped steel below the H-shaped steel has become a common and effective reinforcement method. Usually, hoisting equipment is used to install the T-shaped steel. However, since the existing hoisting equipment supports are installed at high places and are quite long, they are prone to swaying in severe weather conditions such as strong winds, increasing the difficulty of positioning and reducing work efficiency.

[0004] To address these issues, we designed a high-efficiency hoisting device for reinforcing T-shaped steel in photovoltaic factory buildings. Utility Model Content

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a high-efficiency hoisting device for reinforcing T-shaped steel in photovoltaic factory buildings, including a base 1 and a support 7 mounted on the base 1. A base plate is connected to the top surface of the base 1, and an A-frame support 10 is welded to the base plate. The welding method improves the connection strength between the A-frame support 10 and the base plate. A column 4 is also mounted on the base 1. The other end of the A-frame support 10 is welded to the outer wall of the support 7. A connecting frame 11 is also connected to the outer wall of the column 4, with the other end of the connecting frame 11 connected to the outer wall of the A-frame support 10. The connecting frame 11 further stabilizes the entire structure. By connecting the column 4 and the A-frame support 10, the force transmission between components is more uniform, enhancing the stability of the entire hoisting device during operation.

[0024] In specific implementation, an A-shaped support frame 10 is provided on the base 1, and a connecting frame 11 is welded between the A-shaped support frame 10 and the column 4. The tip of the A-shaped support frame 10 is welded to the outer wall of the bracket 7, which plays a role in fixing and supporting the bracket 7, preventing the bracket 7 from shaking or becoming unstable during operation in severe weather such as strong winds, and improving the stability of the device.

[0025] See Figure 4As shown, a hydraulic rod 101 is bolted into the base 1. This bolted installation facilitates the installation and disassembly of the hydraulic rod 101, making future maintenance and replacement easier, and also improves the stability of the connection between the hydraulic rod 101 and the base 1. The telescopic end of the hydraulic rod 101 penetrates the outer wall of the base 1 and is connected to a horizontal plate 3. A friction column 301 is connected to the bottom surface of the horizontal plate 3. The friction column 301 is made of rubber. Rubber has good flexibility and a high coefficient of friction. When the hydraulic rod 101 extends, causing the friction column 301 to contact the ground, the properties of the rubber material generate a large frictional force on the ground, preventing displacement of the base 1 during hoisting operations and further enhancing the stability of the entire hoisting device during operation.

[0026] In practice, a hydraulic rod 101 is installed inside the base 1. The other end of the hydraulic rod 101 is connected to a friction column 301 via a horizontal plate 3. When the hydraulic rod 101 is activated, the friction column 301 is moved downward until one end of the friction column 301 is tightly attached to the ground, thereby further improving the stability of the device by utilizing friction.

[0027] See Figure 3 as well as Figure 5 The column 4 is equipped with a drive motor 401. The drive end of the drive motor 401 is connected to a threaded rod 402. A threaded column 5 is threadedly connected to the threaded rod 402. As the threaded rod 402 rotates, based on the transmission principle of the thread, the threaded column 5 will move up and down along the axial direction of the threaded rod 402. A guide component is provided on the outer wall of the threaded column 5. A connecting seat 6 is provided between the bracket 7 and the threaded column 5. The connecting seat 6 plays the role of connection and fixation, and firmly connects the bracket 7 and the threaded column 5 together. When the threaded column 5 moves up and down, it can drive the bracket 7 to make corresponding position adjustments through the connecting seat 6 to meet the hoisting requirements of T-shaped steel at different heights.

[0028] The guide assembly includes a slide groove 403, in which a slider 404 is slidably connected. The slider 404 is connected to the outer wall of the threaded column 5. When the threaded column 5 moves up and down under the drive of the threaded rod 402, the slider 404 will slide synchronously in the slide groove 403, thereby guiding and limiting the movement of the threaded column 5.

[0029] See Figure 3A connecting box 12 is welded to the outer wall of the threaded column 5. A rotary motor 1201 is installed inside the connecting box 12. A fixed pulley 801 is connected to the drive end of the rotary motor 1201, and a wire rope 8 is wound around the fixed pulley 801. A movable pulley 802 is connected to the connecting seat 6. A movable pulley 803 is connected to the end of the bracket 7 away from the connecting seat 6. The other end of the wire rope 8 is wound around the movable pulley 802 and overlaps the movable pulley 803. When the rotary motor 1201 drives the fixed pulley 801 to rotate, the wire rope 8 moves between the fixed pulley 801, the movable pulley 802, and the movable pulley 803. Utilizing the labor-saving properties of the movable pulley and the ability of the pulley system to change the direction of force, the lifting and handling of T-shaped steel can be achieved more easily, greatly improving the efficiency of hoisting operations.

[0030] See Figure 1 The threaded column 5 and the connecting seat 6 are connected by bolts. The other end of the wire rope 8 is connected to a connecting hook. A T-shaped steel frame 9 is installed outside the base 1. The T-shaped steel frame 9 is connected to the wire rope 8 via the connecting hook. A brake wheel 2 is installed on the bottom surface of the base 1. When it is necessary to move the device to different working positions, it can be easily pushed forward. When the device reaches the designated position to start working, the braking function of the brake wheel 2 can quickly and firmly fix the device in the current position, preventing the safety and accuracy of the hoisting operation from being affected by the movement of the device during the hoisting of the T-shaped steel frame 9.

[0031] Working principle: An A-frame support 10 is installed on the base 1. A connecting frame 11 is welded between the A-frame support 10 and the column 4. The tip of the A-frame support 10 is welded to the outer wall of the support 7, which provides fixed support for the support 7 and prevents the support 7 from shaking or becoming unstable during operation in severe weather such as strong winds, thus improving the stability of the device. A hydraulic rod 101 is also installed inside the base 1. The other end of the hydraulic rod 101 is connected to a friction column 301 via a horizontal plate 3. When the hydraulic rod 101 is activated, it moves the friction column 301 downward until one end of the friction column 301 is tightly pressed against the ground, further improving the stability of the device by utilizing friction. When reinforcing the factory building, a straight boom aerial work platform is used to install temporary T-shaped steel frames 9 on the original A-frame. Four T-shaped steel frames 9 are installed on each A-frame. The temporary support frame must meet the load-bearing requirements before using a crane to lift the T-shaped steel frame 9 from the gas ventilator. The crane will lift the T-shaped steel frame 9 to the preset height and place it inside the temporary support frame. Personnel will then move it to the designated location.

[0032] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
