In the figure: 1. a cross beam; 2. hole turning; 3. fixing a column; 4. a hook; 5. a threaded rod; 6. a nut; 7. a through hole; 8. a bolt; 9. a groove; 10. a gear lever; 11. a gasket; 12. a limiting groove; 13. riveting; 14. and a reinforcing protrusion.

Detailed Description

Any feature disclosed in this specification may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The anti-drop lifting hook for the hook machine comprises a cross beam 1, a rotary hole 2, a fixed column 3, a hook 4, a threaded rod 5, a nut 6, a bolt 8 and a blocking rod 10, wherein the rotary hole 2 is formed in the middle of the cross beam 1, the inner wall of the rotary hole 2 is rotatably connected with the fixed column 3, the bottom of the fixed column 3 is fixedly provided with the hook 4, one end, far away from the hook 4, of the fixed column 3 is fixedly provided with the threaded rod 5, one end of the threaded rod 5 is in threaded connection with the nut 6, the middle parts of the nut 6 and the threaded rod 5 are respectively provided with a through hole 7, the inner wall of the through hole 7 is inserted with the bolt 8, the nut 6 is fixedly connected with the threaded rod 5 through the bolt 8, the upper end of the inner wall of the hook.

And a gasket 11 is sleeved at one end of the fixed column 3 close to the nut 6, so that the abrasion of the nut 6 is reduced.

The inner wall of the hook 4 is provided with a limiting groove 12 matched with the stop lever 10, and one end of the stop lever 10 is clamped with the limiting groove 12, so that the stop lever 10 is limited conveniently.

Rivets 13 are symmetrically fixed on the outer side of the cross beam 1, so that the cross beam 1 and the pulley block shell can be conveniently installed.

The reinforcing protrusions 14 are symmetrically and integrally formed on the two sides of the hook 4, so that the strength and the abrasion thickness of the hook 4 can be conveniently enhanced, and the service life of the hook is prolonged.

The working principle of the specific embodiment is as follows: when the hook is used, the beam 1 is riveted with the pulley block shell through the rivet 13, at the moment, the fixing column 3 and the threaded rod 5 on the hook 4 are inserted into the rotating hole 2 in the middle of the beam 1, the nut 6 is screwed into the threaded rod 5 until the through hole 7 on the threaded rod 5 is coincident with the through hole 7 on the nut 6, at the moment, the bolt 8 is inserted into the through hole 7 to fix the threaded rod 5 and the nut 6, the nut 6 is prevented from loosening, the installation of the hook 4 is finished, when the hook is used, the nut 6 cannot be loosened when the hook 4 rotates along with the swinging of goods in time, the hook 4 and the beam 1 are prevented from falling off, the inner wall of the groove 9 formed in the hook 4 is rotatably connected with the baffle rod 10 through the torsion hinge, when people hang the steel cable on the hook 4, the steel cable extrudes the baffle rod 10 to turn over the baffle rod 10, the opening of the hook 4 is opened, when the steel cable enters the hook 4, the steel cable is separated from the stop lever 10, so that the stop lever 10 is turned upwards to close the opening of the hook 4, and one end of the stop lever 10 is clamped in the limiting groove 12, so that the stop lever 10 limits the steel cable and prevents the steel cable from falling off from the hook 4.
