[0003] When existing hooks are in use, building materials are usually directly suspended on the hooks, and then the hooks and building materials are driven to rise by lifting equipment to transport the building materials to high places. However, a notch is usually opened at the hanging position of existing hooks for hanging objects. During the upward transportation of building materials, the hooks are prone to sliding, which easily causes the building materials to fall off the hooks, posing a great safety hazard.
[0004] In summary, there is an urgent need for an anti - falling crane hook for construction engineering to solve the above problems. Content of the Utility Model
[0005] In order to overcome the shortcoming that a notch is usually opened at the hanging position of existing hooks, which is prone to shaking and causing building materials to fall off during rising, the purpose of the utility model is to provide an anti - falling crane hook for construction engineering.

[0009] As a further preferred solution, it further includes a support plate, a limiting ring plate and a scroll spring. Support plates are symmetrically connected to the left and right sides of the left connecting plate in the front - back direction, and support plates are also symmetrically connected to the right and left sides of the right connecting plate in the front - back direction. Limiting ring plates are rotatably arranged between the corresponding left and right support plates. Scroll springs are connected between the left and right sides of the limiting ring plate and the adjacent support plates.
[0010] As a further preferred solution, it further includes damping blocks. Damping blocks are connected between the left and right parts of the limiting ring plate and the adjacent support plates.
[0011] As a further preferred solution, it further includes a connecting block, a rotating rod and a limiting plate.

Detailed implementation manners
[0024] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but not to limit the present utility model.
[0025] Embodiment: A building engineering anti-dropping crane hook. Refer to Figures 1-6 As shown, it includes a connecting plate 1, a pulley 2, a screw member 3, a hook member 4, an anti-slip plate 5, a fixing block 6, a rotating plate 7, a one-way shaft 8, a torsion spring 9, a support plate 10, a limiting ring plate 11, a volute spring 12, a damping block 13, a connecting block 14, a rotating rod 15 and a limiting plate 16. The connecting plate 1 is triangularly arranged. Two pulleys 2 are installed between the upper parts of the two connecting plates 1 through the screw member 3. A hook member 4 is installed between the lower parts of the two connecting plates 1 through the screw member 3. The hook member 4 is used for hanging building materials. An anti-slip plate 5 is connected to the inner side of the hook member 4. The anti-slip plate 5 is arc-shaped and fits with the hook member 4. A fixing block 6 is welded to the right side of the hook member 4. A one-way shaft 8 is rotatably arranged on the fixing block 6. A rotating plate 7 is connected to the one-way shaft 8. The rotating plate 7 blocks the hanging notch on the right part of the hook member 4, and can limit the building materials to prevent them from falling off. Torsion springs 9 are symmetrically connected back and forth between the rotating plate 7 and the fixing block 6. Support plates 10 are symmetrically welded back and forth on the left side of the left connecting plate 1, and support plates 10 are also symmetrically connected back and forth on the right side of the right connecting plate 1. Limiting ring plates 11 are rotatably arranged between the left and right corresponding support plates 10. The limiting ring plate 11 can limit the pulling rope when rotating inward to prevent the pulling rope from falling off. Volute springs 12 are connected between the left and right sides of the limiting ring plate 11 and the adjacent support plates 10. Damping blocks 13 are connected between the left and right parts of the limiting ring plate 11 and the adjacent support plates 10. A connecting block 14 is connected to the inner side of the end of the hook member 4. A rotating rod 15 is threadedly arranged on the connecting block 14. A limiting plate 16 is welded to the rotating rod 15. The limiting plate 16 blocks the right side of the rotating plate 7, and the limiting plate 16 is used to support the rotating plate 7.
[0026] When the device needs to be used, people first rotate the limit ring plate 11 outward, causing the scroll spring 12 to deform. Then, they wind the pulling rope on the crane around the two pulleys 2. After winding, release the limit ring plate 11, and the scroll spring 12 returns to its original state, driving the limit ring plate 11 to move inward and reset, so that the limit ring plate 11 blocks the pulling rope, thereby limiting the pulling rope and preventing it from falling off. Subsequently, rotate the limit plate 16. The rotation of the limit plate 16 drives the rotation of the rotating rod 15, causing the rotating rod 15 to move upward. The limit plate 16 rotates and no longer blocks the rotating plate 7. Then, rotate the rotating plate 7 to the left so that it no longer blocks the hanging notch on the hook member 4. The rotation of the rotating plate 7 to the left drives the one-way shaft 8 to rotate to the left, causing the torsion spring 9 to deform. At this time, people can hang the building materials on the hook member 4. After hanging, release the rotating plate 7, and the torsion spring 9 returns to its original state, driving the rotating plate 7 to rotate to the right and reset, so that the rotating plate 7 re-blocks the hanging notch on the hook member 4, thereby being able to limit the building materials and prevent the building materials from falling off during ascent. Subsequently, the limit plate 16 can be reversed, driving the rotating rod 15 to reverse, causing the rotating rod 15 to move downward and reset. The limit plate 16 re-blocks the rotating plate 7, providing a certain support for the rotating plate 7. Finally, start the crane to lift the hook member 4, driving the building materials to rise to the designated position.
