Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel beam and column hoisting technology, and in particular relates to a special hoisting tool for steel beam and column hoisting. Background Technology
[0002] Steel beam and column lifting equipment is a specialized tool used in steel structure construction for the safe and efficient lifting of steel beams, columns, and other components. Steel beams are mostly H-beams, I-beams, or box-shaped sections. During lifting, deformation must be avoided and the center of gravity must be kept stable. They are mainly lifted using a combination of beam clamps and lifting lugs. Steel columns are mostly box-shaped, cross-shaped, or circular tube sections. They are tall and have a high center of gravity, so verticality must be controlled during lifting. They are mainly lifted using column top lifting equipment, turning lifting equipment, and integrated main reinforcement lifting equipment.
[0003] Currently, most steel beams and columns are hoisted using specialized lifting equipment. However, when hoisting steel beams, the size of the lifting equipment is often difficult to match the size of the beams, causing them to tilt during hoisting. Therefore, a specialized lifting equipment for steel beams and columns is needed. The size of the clamps can be adjusted by adjusting the structure to prevent the lifting equipment from tilting when hoisting larger steel beams, thus ensuring the safety of the hoisting.

A row of connecting plates is fixedly connected to both the front and back of a fixed frame 4, which is fixedly connected to the adjustable frame 2 via the connecting plates. The output end of the telescopic rod 3 extends through the outside of the lifting frame 1 and is fixedly connected to the adjustable frame 2. A fixed frame 4 is fixedly connected to the bottom of the adjustable frame 2. Two symmetrical sliding grooves 5 are formed at the bottom of the fixed frame 4, with a sliding carriage 6 slidably connected to the inner cavity of each groove 5. The sliding carriage 6 is I-shaped. A rope is installed inside the inner cavity of the lifting wheel 13, and a top anti-slip plate 15 is provided with… The slide 6 has anti-slip textures. The top and bottom of the inner cavity of the slide 6 are rotatably connected to two rows of symmetrical pulleys 7. The pulleys 7 fit into the fixed frame 4. The bottom of the slide 6 is fixedly connected to a clamp 8. The inner cavities of the two slide grooves 5 are rotatably connected to a double-threaded rod 9. The double-threaded rod 9 passes through the slide 6 and is threadedly connected to the slide 6. The surface of the double-threaded rod 9 is fixedly connected to a bevel gear 10. The top of the inner cavity of the fixed frame 4 is rotatably connected to a bevel gear 11. The bevel gear 10 and the bevel gear 11 mesh.

The output shaft of the motor 12 passes through the inner cavity of the fixed frame 4 and is fixedly connected to the bevel gear 11. The top of the hanger 1 is fixedly connected to four symmetrical hanger wheels 13.
[0023] The above scheme is adopted: the steel column is hoisted by the lifting ring at the bottom of the hanger 1, the hanger 1 is placed on the top of the steel beam, the two symmetrical telescopic rods 3 are activated, the two symmetrical adjusting frames 2 move in opposite directions, the motor 12 is started, the bidirectional threaded rod 9 moves threadedly with the two symmetrical slides 6, and the two symmetrical slides 6 are clamped by the limiting of the slide groove 5, so as to avoid the lifting equipment from tilting when hoisting a large steel beam and ensure the safety of the hoisting.
[0024] refer to Figure 4 and Figure 6 The bottom of the slide 6 is fixedly connected with two rows of symmetrical pulleys 14. The bottom of the inner cavity of the clamp 8 is fixedly connected with an anti-slip plate 15. Both sides of the hanger 1 are fixedly connected with two symmetrical fixed plates 16.

Place the hanger 1 on top of the steel beam, activate the two symmetrical telescopic rods 3, which drive the two symmetrical adjusting frames 2 to move in opposite directions to a suitable length. Start the motor 12, which drives the bidirectional threaded rod 9 to rotate through the bevel gear 11 and bevel gear 10. This causes the bidirectional threaded rod 9 to move in a threaded motion with the two symmetrical slides 6. Through the limiting of the slide groove 5, the two symmetrical slides 6 drive the two symmetrical clamps 8 to move in opposite directions, so that the two symmetrical clamps 8 clamp the flange of the steel beam. At this time, the hanger 1 can be lifted by the lifting wheel, so that the hanger 1 can lift the steel beam. This prevents the lifting device from tilting when lifting a large steel beam, ensuring the safety of the lifting.

The lifting frame 1 is placed on top of the steel beam, and the two symmetrical telescopic rods 3 are activated, causing the two symmetrical adjusting frames 2 to move in opposite directions. The motor 12 is started, causing the bidirectional threaded rod 9 to move threadedly with the two symmetrical slides 6. Through the limiting of the sliding groove 5, the two symmetrical slides 6 move in opposite directions to clamp the flanges of the steel beam, preventing the lifting equipment from tilting when hoisting large steel beams and ensuring the safety of the hoisting.
