[0002] Lifting equipment is used for lifting and transporting heavy objects. By tying a rope to the heavy object and then placing the rope in the hook, the heavy object is lifted by the hook on the lifting equipment. According to the special equipment safety technical specifications, it is required that the hook of the lifting equipment must be designed with a rope locking structure to prevent the rope of the lifted heavy object from detaching from the hook during the hoisting process;
[0003] However, the existing rope locking mechanism on the lifting equipment can only ensure that the lifting rope will not detach from the hook, but the lifting rope will still move inside the hook, resulting in the lifted heavy object shaking when the lifting equipment drives the heavy object to move. If the shaking amplitude is too large, it is easy to cause the heavy object to fall and cause danger. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:
[0020] In this technical solution, a lifting device with a safety structure includes a crane 1 and a hook 2. A hook 2 is installed under the boom of the crane 1 through a rope. A lifting rope 3 is hung inside the hook 2, and the lifting rope 3 is tied to an external heavy object. A rope locking mechanism 4 is installed inside the hook 2, and the rope locking mechanism 4 can fix the lifting rope.
[0021] The rope locking mechanism 4 includes a limit block 41, a rotating plate 42, a threaded hole 43, a relief groove 44, a bolt 45 and a tapered block 46. A limit block 41 is installed on the inner side wall of the hook 2. The side wall of the limit block 41 is in contact with the side wall of the lifting rope 3. A rotating plate 42 is rotatably installed on the side wall of the limit block 41, and the rotating plate 42 can be pressed above the lifting rope 3. A threaded hole 43 is opened on the outer side wall of the hook 2, and a relief groove 44 is opened on the inner side wall of the hook 2. The threaded hole 43 is communicated with the relief groove 44. A bolt 45 is rotatably installed in the threaded hole 43, and a tapered block 46 is installed at one end of the bolt 45 located in the relief groove 44. The tapered block 46 can be pressed above the rotating plate 42.
[0022] In this technical solution, when the lifting device is in use, first tie the lifting rope 3 to the heavy object to be moved, and then hang the lifting rope 3 on the hook 2, so that the heavy object can be driven by the crane 1 to move. In order to prevent the heavy object from shaking due to the movement of the lifting rope 3 during the movement, the device also sets a rope locking mechanism 4 inside the hook 2 to fix the lifting rope 3 through the rope locking mechanism 4, so that the device is more stable and safer after lifting the heavy object, and accidents are avoided.
[0023] When locking the lifting rope 3, first rotate the rotating plate 42 above the lifting rope 3, and then rotate the bolt 45 to push the tapered block 46 out of the relief groove 44 and press the rotating plate 42, so as to achieve the purpose of locking the lifting rope 3.
[0024] In some technical solutions, an installation hole 5 is formed in the side wall of the rotating plate 42, and a fixing shaft 6 is inserted and installed in the side wall of the limiting block 41. The fixing shaft 6 penetrates through the side wall of the limiting block 41 and is inserted and installed in the installation hole 5. Sealing rings 7 are fitted and installed on both the left and right sides of the rotating plate 42. The sealing rings 7 are arranged outside the installation hole 5, and the sealing rings 7 can be in contact with the inner wall of the limiting block 41.
[0025] In this technical solution, the rotating plate 42 is rotationally installed on the limiting block 41 through the cooperation of the installation hole 5 and the fixing shaft 6, enabling the rotating plate 42 to rotate around the fixing shaft 6. In addition, sealing rings 7 are provided on both sides of the rotating plate 42 to prevent the fixing shaft 6 from coming into contact with external rainwater during rainy days, which may cause rust and affect the rotation of the rotating plate 42.
[0026] In some technical solutions, a rubber ring 8 is fitted and installed on one side of the tapered block 46 located in the relief groove 44, and the rubber ring 8 can be in contact with the inner wall of the relief groove 44.
[0027] In this technical solution, the cooperation between the rubber ring 8 and the tapered block 46 can block the relief groove 44, preventing rainwater from entering the threaded hole 43 through the relief groove 44 during rainy days and avoiding rust of the bolt 45.
[0028] In some technical solutions, a rotating handle 9 is installed at one end of the bolt 45 located outside the threaded hole 43. A rain shield 10 is installed on the side wall of the rotating handle 9. The rain shield 10 is sleeved outside the bolt 45. An annular groove 11 is formed in the side wall of the hook 2, and the annular groove 11 is located outside the threaded hole 43. The rain shield 10 can be inserted and installed in the annular groove 11.
[0029] In this technical solution, the provision of the rotating handle 9 facilitates the rotation of the bolt 45 by the staff. Since the rain shield 10 is sleeved outside the bolt 45, it can block rainwater. Moreover, with the rain shield 10 and the rubber ring 8, the threaded hole 43 and the relief groove 44 can be in a sealed state, preventing the entry of external impurities and rainwater.
[0030] In some technical solutions, anti-slip grooves 12 are formed in the side walls of both the limiting block 41 and the rotating plate 42.
[0031] In this technical solution, the anti-slip grooves 12 can increase the friction between the limiting block 41, the rotating plate 42 and the lifting rope 3, achieving a better fixing effect.
[0032] In some technical solutions, a clamping block 13 is installed on the side wall of the rotating plate 42, and the clamping block 13 can be in contact with the side wall of the lifting rope 3.
[0033] Working principle: When the lifting device is in use, the lifting rope 3 is first tied to the heavy object to be moved, and then the lifting rope 3 is hung on the hook 2, so that the heavy object is moved by the crane 1. In order to prevent the heavy object from shaking due to the movement of the lifting rope 3 during the movement, the lifting rope 3 needs to be fixed by the rope locking mechanism 4 before lifting. When locking the lifting rope 3, the rotating plate 42 is first rotated to the top of the lifting rope 3, and then the bolt 45 is rotated to push the conical block 46 out of the clearance groove 44, and the rotating plate 42 is pressed, so as to achieve the purpose of locking the lifting rope 3;
[0034] After the rope locking mechanism 4 locks the lifting rope 3, the heavy object can be lifted and moved by controlling the crane 1.
