Description

Technical Field

[0001] This utility model relates to the technical field of steel beam hoisting equipment, and specifically to a hoisting device for steel beam installation. Background Technology

[0002] In the field of steel structure engineering, steel beams are the main load-bearing components, and their installation accuracy and efficiency directly affect the stability of the overall structure and construction safety. At present, the installation of steel beams generally adopts the use of lifting equipment in conjunction with wire ropes, hoisting slings and other rigging for hoisting and positioning.

[0003] In actual construction, traditional hoisting methods present a significant technical challenge: steel beams are prone to tilting during hoisting and high-altitude horizontal movement. This problem mainly stems from the following aspects: First, due to the large length of the steel beams, their center of gravity is difficult to accurately determine, and once the hoisting points are fixed, they are difficult to adjust. Second, during lifting or movement, the steel beams are easily affected by external factors such as wind and crane operation swaying, which can cause the steel beams to tilt. Tilting not only prolongs the operation time and reduces construction efficiency, but more seriously, if the tilt angle is too large or even vertical, the steel beam may accidentally fall from the hoisting equipment. Therefore, a device is needed to solve these problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a hoisting device for installing steel beams, including a top plate 1, a hoisting plate 2 for connecting with a hook fixedly connected to the upper surface of the top plate 1, an inverted T-shaped connecting plate 3 fixedly connected to the lower surface of the top plate 1, an extension plate 4 fixedly connected to both sides of the connecting plate 3, multiple extension plates 4 are spaced apart along the extension direction of the connecting plate 3, and an upward-facing fixing groove 5 is opened on the outer side of the extension plate 4 for suspending steel beams. The connecting plate 3 includes a vertical plate fixed perpendicularly to the top plate 1 and a horizontal plate fixed perpendicularly to the bottom of the vertical plate. The bottom of the extension plate 4 is fixedly connected to the horizontal plate, the top of the extension plate 4 is fixedly connected to the top plate 1, and the side of the extension plate 4 facing the vertical plate is attached and fixed to the vertical plate.

[0019] An extension part 6 is fixedly connected to the upper surface of the top plate 1. An adjustment mechanism is provided inside the extension part 6. One end of the adjustment mechanism is rotatably connected to a connecting seat 7. A counterweight block 8 is connected to the lower surface of the connecting seat 7 through a snap-fit ​​mechanism.

[0020] The lifting plate 2 is connected to the hook of a crane, tower crane, or other lifting equipment, allowing the lifting equipment to lift and move the top plate 1 below the lifting plate 2. The steel beam is hung in the fixing groove 5 on one side of the extension plate 4 by wire rope or other fixing equipment, so that the steel beam and the connecting plate 3 form a whole. There are multiple extension plates 4, and the appropriate position of the extension plate 4 can be selected for hanging according to the length of the steel beam. When the steel beam is long, the connection position is moved to both sides to prevent the steel beam from bending due to hanging in the middle. After being lifted, the adjustment mechanism in the extension part 6 can push the connecting seat 7 to one side, so that the connecting seat 7 moves outward a certain distance. The other end of the connecting seat 7 is equipped with a counterweight 8. When the connecting seat 7 moves outward, the counterweight 8 will also move outward, thereby changing the center of gravity position of the top plate 1. When the top plate 1 tilts, it can be adjusted in the opposite direction to adjust the top plate 1 to a horizontal position, ensuring stability during the lifting process.

[0021] In this embodiment, as a preferred solution, the adjustment mechanism includes a threaded rod 9, an adjustment chamber 10, and a sleeve 11. The adjustment chamber 10 is located inside the extension portion 6, and the sleeve 11 is rotatably connected to the inside of the adjustment chamber 10. The threaded rod 9 is guided and connected to the inside of the adjustment chamber 10 and threadedly connected to the sleeve 11. The extension portion 6 is also provided with a drive mechanism to drive the sleeve 11 to rotate. The drive mechanism includes a drive motor 12 and a drive gear 13. The drive motor 12 is fixedly connected to one side of the extension portion 6, and the drive gear 13 is fixedly connected to the output end of the drive motor 12 through a keyway. The outer circular surface of the drive gear 13 meshes with the outer surface of the sleeve 11 for transmission. The extension portion 6 is also provided with a sliding chamber 14. An auxiliary rod 15 is fixedly connected to one side of the sliding chamber 14. The threaded rod 9 has a guide elongated hole with an opening facing the auxiliary rod 15. The auxiliary rod 15 is guided and slidably inserted into the guide elongated hole. A limit block 16 is fixedly connected to one end of the threaded rod 9 located on the inner wall of the sliding chamber 14.

[0022] The drive motor 12 drives the drive gear 13 at the output end to rotate. The drive gear 13 meshes with the sleeve 11. During the rotation of the sleeve 11 driven by the drive gear 13, the sleeve 11 meshes with the internal threaded rod 9, thereby pushing the threaded rod 9 outward or retracting it inward, thus adjusting the position of the connecting seat 7 at one end of the threaded rod 9. The counterweight 8 is installed at the bottom of the connecting seat 7. By adjusting the position of the connecting seat 7, the center of gravity of the top plate 1 can be adjusted. During the extension and retraction of the threaded rod 9, the auxiliary rod 15 is connected to the threaded rod 9 as a guide to support one end of the threaded rod 9. To prevent the threaded rod 9 from tilting during movement, the limiting block 16 is fixed in a ring shape at one end of the threaded rod 9. After the threaded rod 9 moves to its limit position, the limiting block 16 can fit against the inner wall of the sliding chamber 14 to prevent the threaded rod 9 from continuing to move, thus preventing the threaded rod 9 from accidentally coming out of the sleeve 11. The drive motor 12 can be powered by an external cable or battery and can be connected to external devices using a data cable or wireless signal to perform forward and reverse operation of the drive motor 12 on the ground. The above-mentioned electrical connection and signal connection methods are all means known to those skilled in the art and will not be described in detail here.

[0023] In this embodiment, as a preferred solution, the locking mechanism includes a buckle 17 and an arc-shaped groove 18. The buckle 17 is fixedly connected to the bottom of the connecting seat 7 and the counterweight 8. The arc-shaped groove 18 is formed on the upper surface of the counterweight 8. The buckle 17 and the arc-shaped groove 18 are detachably connected to fix the counterweight 8 to the bottom of the connecting seat 7. A fixing bolt 19 is threadedly connected to one side of the counterweight 8. One end of the fixing bolt 19 penetrates the inner wall of the arc-shaped groove 18 and is connected to the buckle 17 to prevent the buckle 17 from rotating.

[0024] The buckle 17 is L-shaped, and one end of the arc groove 18 has an opening larger than the buckle 17, allowing the buckle 17 to be inserted into the arc groove 18 from one end. After inserting the buckle 17 into the arc groove 18 and rotating it, the buckle 17 and the arc groove 18 can be fixed together, thereby installing the counterweight 8 on the connecting seat 7. Multiple counterweights 8 can be connected using the same connection method, which facilitates the adjustment of the number of counterweights on one side. After the buckle 17 and the arc groove 18 are installed together, the fixing bolt 19 can be screwed into the threaded hole on one side of the counterweight 8, so that one end of the fixing bolt 19 is inserted into the arc groove 18 and plugged into the hole on the surface of the buckle 17, thereby preventing the buckle 17 and the arc groove 18 from rotating relative to each other and ensuring the stability of the connection.

[0025] In this embodiment, as a preferred option, a diagonal tie rod 20 is fixedly connected to the upper surface of the top plate 1, and the other end of the diagonal tie rod 20 is fixedly connected to the hoisting plate 2. The diagonal tie rod 20, the top plate 1, and the hoisting plate 2 form a triangular structure. A plurality of ribs 21 are fixedly connected to the side wall of the connecting plate 3, and the upper surface of the ribs 21 is fixedly connected to the lower surface of the top plate 1.

[0026] Diagonal tie rods 20 are installed on both sides of the hoisting plate 2, forming a triangular structure on both sides of the hoisting plate 2 to improve the stability of the hoisting plate 2 and prevent breakage during hoisting. Rib plates 21 are connected between the top plate 1 and the connecting plate 3 to enhance the connection strength between the two and reduce the possibility of accidental separation.

[0027] In this invention, the working steps of the device are as follows: 1. When using, connect the lifting plate 2 to the hook of the lifting equipment. If necessary, hang the counterweight 8 at the bottom of the connecting seat 7 and fix the position of the counterweight 8 with the fixing bolt 19. Then use the lifting equipment to lift the lifting plate 2 above the steel beam. 2. Use wire ropes or other connection methods to fix the steel beam to the extension plate 4 below the connecting plate 3, so that the steel beam and the connecting plate 3 form a whole. After the connection is completed, lift it. 3. First, lift the steel beam a certain distance and observe whether the lifting position of the steel beam is tilted. If it is tilted, adjust the connecting seat 7 at the higher end, so that the connecting seat 7 at the higher end moves outward and the connecting seat 7 at the lower end moves inward, thereby adjusting the center of gravity of the connecting plate 3. After adjusting to the horizontal position, continue lifting until the steel beam is lifted to the required position. 4. After the hoisting is completed, the steel beam is released, the drive motor 12 resets the connecting seats 7 on both sides, and then moves to the position of the next steel beam to continue the hoisting operation.
