Description

Technical Field

[0001] The utility model relates to the technical field of lifting hooks, in particular to an automatic locking type lifting hook device. Background Technique

[0002] Hoisting refers to the general term for the installation and positioning of equipment by a crane or a hoisting mechanism. During the overhaul or repair process, various hoisting tools are used to lift equipment, workpieces, utensils, materials, etc., so that their positions change. A lifting hook is one of the most common lifting tools in a hoisting machine. The lifting hook is often suspended on the steel wire rope of the hoisting mechanism by means of components such as a pulley block.

[0003] However, during the operation of the traditional lifting hook device, the automation and stability of the lifting hook device are not ideal, and it is impossible to lock the rope or steel wire rope to be lifted. As a result, during the lifting process, the steel wire rope will shake. This operation will make the steel wire rope easy to unhook, resulting in losses of goods and casualties of personnel, and it is very dangerous. Therefore, there is an urgent need for an automatic locking type lifting hook device to solve such problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an automatic locking type lifting hook device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automatic locking type lifting hook device includes a hook body. A steel wire rope is arranged on the inner wall of the hook body. A sealing mechanism for sealing the steel wire rope is arranged at the top of one end of the hook body. Locking mechanisms for automatically locking the steel wire rope are arranged on both sides of the sealing mechanism;

[0007] The locking mechanism includes a U-shaped rotating plate. A sliding rod is slidably arranged on the top of the U-shaped rotating plate, and the bottom of the sliding rod penetrates through the bottom of the U-shaped rotating plate. Second mounting blocks are fixed on the outer walls of the two sides of the top of the U-shaped rotating plate. The same rotating rod is rotatably connected to the surfaces of the two second mounting blocks close to each other. The two sides of the rotating rod penetrate through the two sides of the two second mounting blocks. Eccentric blocks are fixed on the outer walls of the two sides of the rotating rod. Anti-slip teeth are fixed at the bottom of the eccentric blocks, and the eccentric blocks cooperate with the steel wire rope. When the rotating rod rotates, at this time, the eccentric blocks will drive the anti-slip teeth to squeeze and lock the top of the steel wire rope.

[0008] As a further solution of the utility model, the sealing mechanism includes a first fixing plate fixed to the top of one end of the hook body. First mounting blocks are fixed to both sides of the top of the first fixing plate. A rotating shaft is rotatably connected to the side of the two first mounting blocks facing each other. A U-shaped rotating plate is fixed to the outer wall of the rotating shaft. One of the first mounting blocks is rotatably connected to a rotating block on the outer wall of one side, and the rotating block is rotationally connected to one end of the U-shaped rotating plate by a rotating shaft.

[0009] As a further solution of the utility model, a second fixing plate is fixed to one end of the inner wall of the hook body. An arc-shaped clamping groove communicating with each other is opened at the top of the second fixing plate close to the U-shaped rotating plate. An arc-shaped clamping block is fixed to the bottom of one end of the U-shaped rotating plate close to the second fixing plate, and the arc-shaped clamping block is adapted to the arc-shaped clamping groove. When the arc-shaped clamping block is stuck in the inner wall of the arc-shaped clamping groove, the U-shaped rotating plate will seal the steel rope to prevent it from falling off at this time.

[0010] As a further solution of the utility model, a first notch is opened on the outer wall of one end of the sliding rod. A rack is fixed to one end of the inner wall of the first notch. A gear is fixed to the outer wall of the rotating rod, and the gear meshes with the rack.

[0011] As a further solution of the utility model, a fixing ring is fixed to the bottom of the outer wall of the sliding rod. A U-shaped hook is fixed to the bottom of the fixing ring, and the steel rope is adapted to the top of the inner wall of the U-shaped hook.

[0012] As a further solution of the utility model, a spring is fixed to the bottom of the U-shaped rotating plate. The bottom of the spring is fixed to the top of the fixing ring, and the spring is located on the outer wall of the sliding rod.

[0013] As a further solution of the utility model, a lifting ring is fixed to the top of the hook body.

[0014] The beneficial effects of the utility model are as follows:

[0015] In the utility model: by providing a locking mechanism, when the hook body pulls the goods through the steel rope, the steel rope will drive the U-shaped hook to press down at this time. The rotating rod will drive the eccentric blocks on both sides to rotate at this time. When the pulling force of the steel rope on the U-shaped hook is greater, the anti-slip teeth will press the steel rope tighter at this time, thereby realizing the effect of automatically locking the steel rope.

[0016] In the utility model: by providing a sealing mechanism, by rotating the rotating block, the rotating block will drive the U-shaped rotating plate to rotate at this time. The arc-shaped clamping block will be stuck in the inner wall of the arc-shaped clamping groove at this time. Then the steel rope is hung on the top of the inner wall of the U-shaped hook, thereby realizing the effect of sealing the steel rope to prevent it from falling off. Description of the drawings

Anti-slip teeth 21 are fixed to the bottom of the eccentric blocks 20, and the eccentric blocks 20 cooperate with the steel rope 3. When the rotating rod 17 rotates, at this time, the eccentric blocks 20 will drive the anti-slip teeth 21 to squeeze and lock the top of the steel rope 3.

[0025] In this embodiment, the sealing mechanism includes a first fixing plate 4 fixed to the top of one end of the hook body 1. On both sides of the top of the first fixing plate 4, first mounting blocks 6 are fixed. A rotating shaft is rotatably connected to the mutually approaching surfaces of the two first mounting blocks 6. An outer wall of the rotating shaft is fixed with a U-shaped rotating plate 8. One side outer wall of one of the first mounting blocks 6 is rotatably connected to a rotating block 7, and the rotating block 7 is rotationally connected to one end of the U-shaped rotating plate 8 by a shaft.

[0026] In this embodiment, a second fixing plate 5 is fixed to one end of the inner wall of the hook body 1. An arc-shaped card slot 9 that communicates is opened at the top of the second fixing plate 5 close to the U-shaped rotating plate 8. An arc-shaped card block 10 is fixed to the bottom of one end of the U-shaped rotating plate 8 close to the second fixing plate 5, and the arc-shaped card block 10 is adapted to the arc-shaped card slot 9. When the arc-shaped card block 10 is stuck in the inner wall of the arc-shaped card slot 9, at this time, the U-shaped rotating plate 8 will seal the steel rope 3 to prevent it from falling off.

[0027] In this embodiment, a first notch 13 is opened on an outer wall of one end of the sliding rod 11. A rack 14 is fixed to one end of the inner wall of the first notch 13. A gear 18 is fixed to an outer wall of the rotating rod 17, and the gear 18 meshes with the rack 14.

[0028] In this embodiment, a fixing ring 15 is fixed to the bottom of the outer wall of the sliding rod 11. A U-shaped hook 12 is fixed to the bottom of the fixing ring 15, and the steel rope 3 is adapted to the top of the inner wall of the U-shaped hook 12.

[0030] In this embodiment, a lifting ring 2 is fixed to the top of the hook body 1.

[0031] Working principle: When in use, first fix the lifting ring 2 to the crane through a lifting rope, and then rotate the rotating block 7. At this time, the rotating block 7 will drive the U-shaped rotating plate 8 to rotate. At this time, the U-shaped rotating plate 8 will drive the arc-shaped clamping block 10 to rotate. At this time, the arc-shaped clamping block 10 will be stuck in the inner wall of the arc-shaped clamping groove 9. Then hang the steel rope 3 on the top of the inner wall of the U-shaped hook 12, thereby achieving the effect of sealing the steel rope 3 to prevent it from falling. At this time, start the crane and lift the hook body 1. When the hook body 1 pulls the goods through the steel rope 3, at this time, the steel rope 3 will drive the U-shaped hook 12 to press down. At this time, the U-shaped hook 12 will drive the sliding rod 11 to move downward. At this time, the sliding rod 11 will drive the rack 14 to move downward. At this time, the rack 14 will drive the gear 18 to rotate the rod. At this time, the gear 18 will drive the rotating rod 17 to rotate. At this time, the rotating rod 17 will drive the eccentric blocks 20 on both sides to rotate. At this time, the eccentric blocks 20 will drive the anti-slip teeth 21 to squeeze the top of the steel rope 3. When the pulling force of the steel rope 3 on the U-shaped hook 12 is greater, at this time, the anti-slip teeth 21 will squeeze the steel rope 3 tighter, thereby achieving the effect of automatically locking the steel rope 3. When the goods are transported to a certain position, at this time, by canceling the pressure of the steel rope 3 on the U-shaped hook 12, at this time, the spring 16 will reset the U-shaped hook 12. At this time, the rack 14 will drive the gear 18 to reverse. At this time, the gear 18 will drive the eccentric block 20 away from the top of the steel rope 3. At this time, by rotating the rotating block 7, the U-shaped rotating plate 8 can be opened, and then the steel rope 3 can be removed.
