Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to an anti-jamming lifting equipment. Background Technology

[0002] Lifting slings are devices or tools used for lifting and moving objects. They are widely used in many fields such as logistics, construction, and manufacturing. According to their structural form, they can be divided into rigging, clamps, and lifting beams. The main function of lifting slings is to connect lifting equipment to the object being lifted. Through reasonable design and structure, the weight of the object can be evenly distributed, ensuring the stability and safety of the object during the lifting process.

[0003] The clamps in a lifting device typically include grippers, an adjustment mechanism, a connecting device, and a power source. The grippers are used to hold and fix the object being lifted. The adjustment mechanism is used to adjust the spacing and clamping force of the grippers through the hinge principle. At the same time, the adjustment mechanism is usually equipped with a crossbeam to guide the grippers. The connecting device is used to connect the clamps to the lifting equipment. The power source provides power for clamping and releasing the clamps.

[0004] Considering that during the clamping and releasing movements of existing lifting devices, the jaws rub against the crossbeam, causing the lubricating medium between the jaws and the crossbeam to wear away. At the same time, the wear between the jaws and the crossbeam over a long period of time will create a certain gap, causing the jaws to tilt relative to the crossbeam. This will cause the jaws to jam when clamping and releasing objects, thus reducing the effectiveness and safety of the lifting device. Utility Model Content

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0024] Reference Figure 1 and Figure 2 The image shows an anti-jamming lifting device, comprising a lifting device body 1, a hook 2, a movable column 3, a crossbeam 4, a guide mechanism 5, and an oil injection mechanism 6. The hook 2 and crossbeam 4 are hinged to the lifting device body 1. The lifting device body 1 drives the hook 2 to move, performing clamping and releasing actions. The hook 2 and crossbeam 4 are connected by the movable column 3, which is slidable relative to the crossbeam 4. The movable column 3 and crossbeam 4 guide the hook 2, preventing it from shifting during movement. The guide mechanism 5 guides the movable column 3 during sliding, further improving the stability of the hook 2 during movement and preventing jamming. The oil injection mechanism 6 injects lubricating oil into the guide mechanism 5, thus facilitating lubrication of the movable column 3.

[0025] Reference Figures 2 to 4The guiding mechanism 5 includes a cylindrical tube 51 and a ball bearing 52. The cylindrical tube 51 is fixedly installed on the crossbeam 4. The cylindrical tube 51 is a hollow cylinder and contains lubricating oil. The ball bearing 52 is rotatably mounted on the cylindrical tube 51. Because the cylindrical tube 51 contains lubricating oil, when the ball bearing 52 rotates, the lubricating oil can adhere to the surface of the ball bearing 52, thereby improving the smoothness of the movement of the moving column 3. The moving column 3 has a cross groove 55. The cylindrical tube 51 and the ball bearing 52 are slidably connected to the cross groove 55. The cylindrical tube 51 and the cross groove 55 guide the moving column 3. At the same time, when wear gaps occur between the moving column 3 and the crossbeam 4, the moving column 3 is supported to prevent it from shifting.

[0026] Reference Figures 2 to 4 The guide mechanism 5 also includes a rotating wheel 53 and a lubrication mechanism 57. The rotating wheel 53 is rotatably mounted on the moving column 3 via the mounting column 54. A groove 56 is provided on the crossbeam 4. The rotating wheel 53 is slidably connected to the groove 56. Through the sliding effect of the rotating wheel 53 and the groove 56, the friction between the moving column 3 and the crossbeam 4 is further reduced. The lubrication mechanism 57 is used to lubricate the rotating wheel 53, thereby further improving the smoothness of the moving column 3 when it moves.

[0027] Reference Figure 2 and Figure 5 The lubrication mechanism 57 includes a baffle 572, a guide rod 573, and a top column 575. An oil storage chamber 576 is provided on the crossbeam 4, and the oil storage chamber 576 is connected to a sliding groove 56. By opening the connection between the oil storage chamber 576 and the sliding groove 56, lubricating oil in the oil storage chamber 576 can enter the sliding groove 56. The oil storage chamber 576 is connected to a cylindrical cylinder 51 via a connecting pipe 571, allowing lubricating oil in the cylindrical cylinder 51 to enter the oil storage chamber 576. The baffle 572 is connected to the oil storage chamber 576 by a spring 574, and the baffle 572 and the oil storage chamber 576 are slidably connected. Through the elastic force of the spring 574, the baffle 572... 72. Under no external force, the connection between the oil storage chamber 576 and the slide groove 56 is always closed. The guide rod 573 is fixedly installed in the oil storage chamber 576 and passes through the baffle 572. The guide rod 573 guides the baffle 572 to prevent the baffle 572 from shifting when it moves. The top column 575 is fixedly installed on the baffle 572. When the rotating wheel 53 moves to a certain position along the slide groove 56, it can squeeze the top column 575, so that the baffle 572 squeezes the spring 574 and opens the connection between the oil storage chamber 576 and the slide groove 56, so that the lubricating oil can enter the slide groove 56 to lubricate the rotating wheel 53.

[0028] Reference Figure 2 and Figure 6The oil injection mechanism 6 includes an oil inlet pipe 61, a round block 62, a sealing gasket 63, and a cylindrical sleeve 64. The oil inlet pipe 61 is fixedly installed on the cylindrical cylinder 51 and passes through the crossbeam 4. Through the oil inlet pipe 61, it is convenient for the operator to add lubricating oil into the cylindrical cylinder 51. The round block 62 is fixedly installed on the oil inlet pipe 61, and the sealing gasket 63 is fixedly installed on the cylindrical sleeve 64. Through the insertion effect of the cylindrical sleeve 64 and the round block 62, the sealing gasket 63 can be squeezed, causing the sealing gasket 63 to undergo elastic deformation, improving the sealing performance of the oil inlet pipe 61 and preventing lubricating oil leakage. The cylindrical sleeve 64 is inserted into the round block 62. The oil injection mechanism 6 also includes a locking post 65, which is connected to the round block 62 via a limiting spring 66. The locking post 65 and the round block 62 are slidably connected. Through the elastic force of the limiting spring 66, the locking post 65 is always locked with the locking groove 67 when no external force is applied. The cylindrical sleeve 64 is provided with a locking groove 67. The limiting spring 66 is used to press the locking post 65 and the locking groove 67 to lock together. Through the locking effect of the locking post 65 and the locking groove 67, the cylindrical sleeve 64 can be limited, so that the cylindrical sleeve 64 remains fixed.

[0029] This anti-jamming lifting device, through its guide and lubrication mechanisms, provides stable guidance for the moving column, reduces friction between the column and the crossbeam, and automatically adds lubricating oil to the column to prevent jamming. This improves the device's performance and safety. Furthermore, the oil injection mechanism facilitates the addition of lubricating oil to the cylindrical section of the guide mechanism, while also improving the sealing of the oil inlet pipe to prevent leakage, further enhancing the device's effectiveness and work efficiency.

Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model.
