DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-4 A steel component hoisting device with anti-falling function includes a hook 100, an anti-falling strip 200 hinged to the surface of the hook 100, a torsion spring 300 installed between the anti-falling strip 200 and the hook 100, and a positioning mechanism 400 fixedly connected to the surface of the hook 100.

[0029] Workers first use custom-made lifting frames to hoist steel components in batches as needed. Then, they fix the hooks 100 to the corresponding positions on the lifting frames using existing methods such as bolts. Finally, they fix the lifting frames to the hoisting area of ​​the crane using the same methods. During hoisting, the crane is first positioned directly above the steel component. Then, the anti-detachment strip 200 is pressed, opening the notch in the hook 100. The connectors of the steel component are then inserted into the hook 100. The anti-detachment strip 200 is then released, and the torsion spring 300 causes the anti-detachment strip 200 to quickly press against the hook 100, confining the connectors of the steel component within the hook 100.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism 400 includes a threaded sleeve 410 fixedly connected to the surface of the hook 100. The threaded sleeve 410 is misaligned with the anti-slip strip 200 and the torsion spring 300. A threaded adjusting rod 420 is threadedly connected to the inner side of the threaded sleeve 410. Both ends of the threaded adjusting rod 420 pass through the threaded sleeve 410. A positioning plate 430 is rotatably connected to the bottom of the threaded adjusting rod 420. A guide strip 440 is fixedly connected to the top of the positioning plate 430. The top of the guide strip 440 passes through the threaded sleeve 410. Two rubber bellows 450, which are always in a compressed state, are sleeved on the surface of the threaded sleeve 410. The upper rubber bellows 450 is located between the head of the threaded adjusting rod 420 and the threaded sleeve 410, and the lower rubber bellows 450 is located between the threaded sleeve 410 and the positioning plate 430. The guide strip 440 is located inside the rubber bellows 450.

[0031] like Figure 3 and Figure 4As shown, the threaded sleeve 410 has a mounting cavity 411 on its surface, and the guide bar 440 has a positioning groove 441 at its end facing away from the hook 100. The positioning mechanism 400 includes a locking component 460, which includes an adjusting block 461 slidably connected inside the mounting cavity 411. The end of the adjusting block 461 facing away from the hook 100 extends through the mounting cavity 411, and the end of the adjusting block 461 facing the hook 100 is fixedly connected to a positioning block 462 that engages with the positioning groove 441. The vertical cross-sectional shapes of the positioning groove 441 and the positioning block 462 are both matching right-angled triangles. The inclined surface faces away from the positioning plate 430; the vertical cross-sectional shape of the mounting cavity 411 is convex, and the vertical cross-sectional shape of the adjusting block 461 is T-shaped. The maximum diameter of the adjusting block 461 inside the mounting cavity 411 is larger than the inner diameter of the opening of the mounting cavity 411; a spring 463 is sleeved on the surface of the adjusting block 461, and the two ends of the spring 463 are respectively connected between the mounting cavity 411 and the adjusting block 461; a pull ring 464 is fixedly connected to one end of the adjusting block 461 facing away from the hook 100. By pulling the pull ring 464, the operator can quickly separate the adjusting block 461 and the positioning block 462 to ensure that the positioning block 462 can be smoothly reset.

[0032] During the downward movement of the positioning plate 430, the positioning plate 430 drives the guide bar 440 to move vertically downward. The guide bar 440 drives the inclined surface of the positioning groove 441 to press down on the inclined surface of the positioning block 462 and press the positioning block 462 back into the mounting cavity 411 to ensure that the positioning plate 430 can move downward smoothly. When the positioning plate 430 moves into place, the positioning block 462 is aligned with the corresponding positioning groove 441. The spring 463 drives the positioning block 462 to press into the positioning groove 441 through the adjusting block 461, and makes the positioning block 462 and the downward vertical surface of the positioning groove 441 abut against each other. This can effectively prevent the guide bar 440 from moving upward along with the positioning plate 430, so as to ensure that the positioning plate 430 can stably abut against the connecting parts of the steel component.

[0033] In this embodiment of the utility model, after the worker inserts the connector of the steel component into the hook 100, the worker only needs to rotate the threaded adjusting rod 420 downwards. The threaded adjusting rod 420 moves the positioning plate 430 downwards along the threaded sleeve 410 until the positioning plate 430 is in close contact with the connector of the steel component. When the connector of the steel component shakes inside the hook 100 under the action of external force, the positioning plate 430 can prevent the connector of the steel component from shaking by contact, so that the hook 100 can lift the steel component more stably through the connector of the steel component.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
