[0020] See also Figure 1 - Figure 4 The utility model provides a technical solution: a steel beam lifting structure, including a connecting column 1, a fixed cylinder 2 and a movable column 3. The bottoms of both ends of the connecting column 1 are welded with fixed cylinders 2, and the fixed cylinders 2 play a fixing role. The movable column 3 is embedded in one side of the fixed cylinder 2. A limiting groove 4 is arranged at one end of the movable column 3 close to the fixed cylinder 2. The inner wall of the fixed cylinder 2 away from the movable column 3 is connected with a screw 5 through a bearing, and the screw 5 can rotate in the fixed cylinder 2.

[0021] The end of the screw rod 5 away from the fixed cylinder 2 extends into the limiting groove 4, and the outer wall of the screw rod 5 is threadedly connected with a moving block 6. The rotation of the screw rod 5 can drive the moving block 6 to translate, and the outer wall of the moving block 6 is connected to the inner wall of the limiting groove 4. The movement of the moving block 6 drives the movable column 3 to translate synchronously. A through groove 7 is provided on the side of the fixed cylinder 2 away from the movable column 3. The interior of the through groove 7 is connected with an adjusting knob 8 through a bearing, and the adjusting end of the adjusting knob 8 is connected to the screw rod 5. The screw rod 5 can be driven to rotate by twisting the adjusting knob 8. The rotation of the screw 5 can drive the moving block 6 to translate, and the movement of the moving block 6 drives the movable column 3 to translate synchronously, thereby driving the clamping plate 9 on one side of the moving block 6 to clamp and fix the steel beam.

[0022] A clamping plate 9 is welded to the bottom end of the side opposite to the fixed cylinder 2 and the movable column 3. The clamping plate 9 is L-shaped. The clamping directions of the two groups of clamping plates 9 are opposite. The clamping plates 9 play a role of clamping and fixing. The ends of the fixed cylinder 2 and the movable column 3 are connected with a threaded cylinder 10 through bearings. The threaded cylinder 10 rotates at the ends of the fixed cylinder 2 and the movable column 3 through bearings.

[0023] The bottom end of the threaded barrel 10 is threadedly connected to a threaded rod 11, and the end of the threaded rod 11 away from the threaded barrel 10 is connected to a pressure plate 12. A rotating disk 13 is provided on the top of the end of the fixed barrel 2 and the movable column 3 close to the threaded barrel 10. The bottom axis of the rotating disk 13 is connected to the threaded barrel 10. The threaded barrel 10 can be driven to rotate by rotating the rotating disk 13. The rotation of the threaded barrel 10 drives the threaded rod 11 to move up and down, thereby driving the pressure plate 12 to squeeze and fix the steel beam clamped by the clamping plate 9, thereby preventing loosening during the lifting process.

[0024] A slide groove 14 is provided on the inner wall of one side of the clamping plate 9, and the slide groove 14 plays a limiting role.

Clamping structures are provided on both sides of the connecting column 1 to prevent it from being easily offset during the lifting process. The overall center of the connecting column 1 can be adjusted by adjusting the position of the counterweight block 19, so that the device can achieve the effect of adjusting the balance by moving the counterweight block 19 when lifting steel beams with different centers of gravity, so that it can reach a relatively balanced position for better lifting.

[0026] Working principle: When using the steel beam lifting structure, the steel beam to be lifted is fixed in the middle of the two sets of clamping plates 9. By twisting the adjusting knob 8, the screw rod 5 can be driven to rotate. The rotation of the screw rod 5 can drive the moving block 6 to translate. The movement of the moving block 6 drives the movable column 3 to translate synchronously, thereby driving the clamping plate 9 on one side of the moving block 6 to clamp and fix the steel beam. By rotating the rotating disk 13, the threaded cylinder 10 can be driven to rotate. The rotation of the threaded cylinder 10 drives the threaded rod 11 to translate up and down, thereby driving the pressing plate 12 to squeeze and fix the steel beam clamped by the clamping plate 9, thereby avoiding the process of lifting. Loose, the limit slider 15 and the slide groove 14 play a limiting role to prevent the pressure plate 12 from rotating with the threaded tube 10, and the bottom end of the pressure plate 12 is provided with an anti-skid pad 16, which plays an anti-skid role. The steel beam can be hoisted by cooperating with the crane through the lifting ring 17. Clamping structures are provided on both sides of the connecting column 1 to prevent it from shifting during the hoisting process. The overall center of the connecting column 1 can be adjusted by adjusting the position of the counterweight block 19, so that the device can achieve the effect of adjusting the balance by moving the counterweight block 19 when hoisting steel beams with different centers of gravity, so that it can reach a relatively balanced position for better hoisting.
