[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example: Reference Figures 1-8 The tower crane hook shown in the diagram includes a hook 1. A buffer pad 7 is fitted on the outside of the hook 1 and is secured above the lifting lug 2 with a fixing strap to prevent it from falling. There are grooves on both sides of the buffer pad 7. There are two fixing straps for the buffer pad on the inner wall of the hook 1. The buffer pad 7 is made of rubber and can absorb some of the kinetic energy when the hook 1 hits a hard object, so as to reduce the damage to the hook 1 and extend the life of the hook 1. It is convenient for workers to hold the grooves to stabilize the hook 1 when the lifting rope is hung inside the hook 1, so as to avoid the lifting rope from pinching the worker's hand. The lifting rope can be placed between the two fixing straps to prevent the lifting rope from shaking violently inside the hook 1.

[0033] The first bolt 3 is used to pass through the anti-detachment baffle 4 and the spring 5 on the hook 1 and is fixed to the lifting lug 2. The first nut 6 is screwed into the end of the first bolt 3 clockwise and tightened so that the anti-detachment baffle 4 and the spring 5 can rotate around the first bolt 3 as the axis. The bottom of the anti-detachment baffle 4 is placed into the inner wall of the hook 1 and close to the hook head of the hook 1, which can limit the rotation space of the anti-detachment baffle 4. When the anti-detachment baffle 4 is rotated inward, the spring 5 is used to reset the anti-detachment baffle 4, which can quickly reset the anti-detachment baffle 4 and prevent the hook 1 from shaking when lifting things, causing the lifting rope to slip out of the hook 1.

[0034] The hook head of the hook 1 has a first connecting hole through which a pin 8 passes and the end of a limiting ring 9. At each end of the pin 8 is a second connecting hole into which a second bolt 10 is inserted. A second nut 11 is screwed clockwise into the end of the second bolt 10 and tightened, allowing the limiting ring 9 to rotate around the pin 8. After the lifting rope is placed inside the hook 1, the limiting ring 9 is held above the rope and installed on the hook head. A first stud 12 passes through the baffle 13 and the hook 1 on the hook 1. Third nuts 16 are screwed clockwise into the first stud 12 at both ends and tightened, fixing the hook 1 and the baffle 13 together. The system begins by inserting four second studs 15 sequentially through the baffle 13. Fourth nuts 16 are then screwed clockwise into and tightened on both sides of each second stud 15, fixing the baffle 13 together. The inner wall of the baffle 13 has a first connecting rod 17 and a second connecting rod 18. A rolling shaft 20 is located between the second connecting rods 18, and a bearing 19 is fitted onto the rolling shaft 20. The cable is then looped around the bearing 19, which rests on the cable. Two first connecting rods 17 are located between the baffles 13, securing the cable to them. The baffle 13 has four air guide holes, which can confine the lifting rope to the space below the limiting ring 9 during hoisting to prevent it from falling off. This facilitates smooth raising and lowering of the hook via the cable, helping to maintain the hook's balance during lifting and preventing violent shaking of the hook due to sudden crosswinds during hoisting.

[0035] The balance frame 21 is placed on the baffle 13. There are two lead screws 22 on each side of the balance frame 21. One end of the lead screw 22 has a turntable 23 with a handle 24, which makes it easy to rotate the lead screw 22. The lead screw 22 passes through the limiting plate 25. Rotating the lead screw 22 can move and fix the limiting plate 25. The bottom plate of the balance frame 21 can block some rainwater and prevent rainwater from entering the bearing 19 and affecting its use. The counterweight 26 in the balance frame 21 is fixed by the limiting plate 25. The counterweight 26 prevents the hook 1 from spinning in place when encountering strong winds. The balance frame 21 adopts a truss structure, which is mostly hollow to reduce the impact of strong winds.

[0036] There are four rope hooks 27 at the bottom of the balance frame 21. The opening directions of two rope hooks 27 on the same side are opposite. When hoisting tubular or long objects, the rope can be used to increase the force points and help balance during hoisting. The opposite opening of the rope hooks 27 can prevent the rope from falling off.

[0039] like Figure 1 and Figure 1 As shown in this embodiment, (supplementary part).

[0040] The working principle of this utility model is as follows: A buffer pad 7 is fitted onto the outside of the hook 1 and secured above the lifting lug 2 with a fixing strap to prevent it from falling. The buffer pad 7 has grooves on both sides. There are two fixing straps for the buffer pad on the inner wall of the hook 1. A first bolt 3 passes through the anti-detachment baffle 4 and the spring 5 on the hook 1 and is fixed to the lifting lug 2. A first nut 6 is screwed clockwise into the end of the first bolt 3 and tightened to allow the anti-detachment baffle 4 and the spring 5 to rotate around the first bolt 3 as an axis. The bottom of the anti-detachment baffle 4 is placed inside the inner wall of the hook 1 and close to the hook head of the hook 1 to restrict the rotation of the anti-detachment baffle 4. When rotating the anti-detachment baffle 4 inward, the spring 5 resets the anti-detachment baffle 4. A first connecting hole is located on the hook head of the hook 1. A pin 8 passes through the first connecting hole and the end of the limiting ring 9. There is a second connecting hole at each end of the pin 8. A second bolt 10 is inserted into the second connecting hole. A second nut 11 is screwed clockwise into the end of the second bolt 10 and tightened, allowing the limiting ring 9 to rotate around the pin 8. After the lifting rope is placed inside the hook 1, the limiting ring 9 is held above the lifting rope and installed on the hook head. A first stud 12 passes through the baffle on the hook 1. Plate 13 and hook 1 are fixed together by screwing third nuts 16 clockwise into the first studs 12 at both ends of the first studs 12. Four second studs 15 are then inserted through the baffle 13 in sequence, and fourth nuts 16 are screwed clockwise into the second studs 15 on both sides of the second studs 15 to fix the baffle 13 together. The inner wall of the baffle 13 has a first connecting rod 17 and a second connecting rod 18. A rolling shaft 20 is located in the middle of the second connecting rod 18. A bearing 19 is fitted onto the rolling shaft 20. The cable is then wrapped around the bearing 19, and the bearing 19 is placed on the cable. There are two first connecting rods 17 between the baffles 13, and the cable is fixed to the first connecting rods 17. There are four air guide holes on the baffles 13. The balance frame 21 is placed on the baffles 13. There are two lead screws 22 on each side of the balance frame 21. One end of the lead screw 22 has a turntable 23 with a handle 24, which facilitates the rotation of the lead screw 22 through the turntable 23. The lead screw 22 passes through the limiting plate 25. Rotating the lead screw 22 can move and fix the limiting plate 25. There are four rope hooks 27 at the bottom of the balance frame 21. The opening directions of two rope hooks 27 on the same side are opposite.
