Description

Technical Field

[0001] The utility model relates to a simple anti-dropping hoisting hook, in particular to a device for improving hoisting safety. Background Art

[0002] There are certain safety hazards in the process of lifting steel plates or parts, such as the lifting rope falling off, the lifting hook not clamping the steel plate, etc. In order to improve the safety and stability of lifting and be economical, the utility model is designed. Summary of the Invention

[0003] The utility model provides a simple anti-fall-off lifting hook, which improves safety.

[0004] The technical method adopted by the utility model to solve the technical problem is as follows: a simple anti-slip hoisting hook is mainly composed of a hoisting hook, an anti-slip card, a spring, an M4 bolt, a connecting ring, an oblique iron, and an M10 screw; the hoisting hook is divided into an upper opening and a lower opening, the upper opening is used to pass the hoisting rope, and the lower opening is used to clamp the steel plate, the M4 bolt passes through the anti-slip card and the spring and is connected to the upper opening of the hoisting hook, the connecting ring passes through the circular hole of the hoisting hook and is movably connected to the hoisting hook, the oblique iron is connected to the connecting ring through the M10 screw, the anti-slip card plays a role in preventing the rope from slipping during the hoisting process, the oblique iron and the hoisting hook are movably connected, and when the hoisting When installing steel plates or parts, insert the bevel iron into the gap between the plate and the lifting hook to prevent the lifting hook from shifting laterally and the hoisted object from falling off. The bevel iron and the anti-fall-off card simultaneously play the role of ensuring the safety of lifting, that is, the lifting rope is passed through the upper mouth of the lifting hook, and the anti-fall-off card has a built-in spring. The lifting rope can enter the upper mouth of the lifting hook from the outside, but cannot go out from the inside on its own. The anti-fall-off card is used to prevent the lifting rope from falling off. The lower mouth of the lifting hook clamps the steel plate or plate parts. Different lower mouth widths can be designed according to different plate thicknesses. The bevel iron is inserted into the gap between the lower mouth and the steel plate to prevent the steel plate or parts from falling off, thereby ensuring lifting safety.

[0005] The advantages of the utility model are: the device has a simple structure, low manufacturing cost and improved safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] like Figure 1 As shown, a simple anti-dropping lifting hook is composed of a lifting hook 1, an anti-dropping card 2, a spring 3, an M4 bolt 4, an M10 screw 5, an oblique iron 6, and a connecting ring 7. The lifting hook 1 is divided into an upper opening and a lower opening. The upper opening is used to pass the lifting rope, and the lower opening is used to clamp the steel plate. The M4 bolt 4 passes through the anti-dropping card 2 and the spring 3 and is connected to the upper opening of the lifting hook 1 to form a closed space. Under the action of the anti-dropping card 2 and the spring 3, the lifting rope can only enter the upper opening of the lifting hook 1 from the outside and cannot go out on its own. Then it plays the role of preventing it from falling off. The connecting ring 7 passes through the round hole of the lifting hook 1 and is movably connected to the lifting hook 1. The oblique iron 6 is connected to the connecting ring 7 by the M10 screw 5. The oblique iron 6 is movably connected to the lifting hook 1. When lifting steel plates or parts, the lower mouth of the lifting hook 1 clamps the steel plate or plate parts. Different lower mouth widths can be designed according to different plate thicknesses. The oblique iron 6 is inserted into the gap between the plate and the lifting hook 1 to prevent the lifting hook 1 from lateral displacement and the hoisted object from falling off, thereby ensuring the safety of lifting. Figure 2 As shown, the bottom of the inclined iron 6 is processed into a grid shape to increase friction; Figure 3 As shown, the use of the utility model ensures safe and stable lifting.

[0012] Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included in the protection scope of the present utility model.
