Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0019] Please see Figures 1-4 This utility model provides a technical solution for a self-lubricating wire rope bridge crane: including a bridge frame 1, a bidirectional rotating motor 2, a worm gear 3, a worm 4, a winding roller 5, a wire rope body 6, a hook 7, a hook body 701, an anti-derailment body 702, a return spring 703, a recovery box 8, a limiting pulley 9, a lubrication structure 10, a lubrication box 1001, a lubrication hole 1002, an oil tank 1003, an upper conveying pipe 1004, a lower conveying pipe 1005, a lubrication roller 1006, an oil pump 11, an oil pipe 12, and an oil filter screen 13.
[0020] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 and Figure 2 As shown, the front side of the worm gear 4 is meshed with a worm wheel 3, and the right end of the worm wheel 3 is integrally fixedly connected to a take-up roller 5. The hook 7 includes a hook body 701, an anti-detachment body 702, and a return spring 703. The anti-detachment body 702 is connected through the left side of the upper opening of the hook body 701. The return spring 703 is sleeved on the outer surface of the anti-detachment body 702. The right end of the anti-detachment body 702 has a spherical structure. The anti-detachment body 702 forms a telescopic structure inside the hook body 701 through the return spring 703. When the power switch of the bidirectional rotating motor 2 is turned on, the bidirectional rotating motor 2 drives the worm gear 4 to rotate. The rotation of the worm gear 4 drives the worm wheel 3 to rotate, thereby facilitating the rotation of the take-up roller 5 and facilitating the winding and unwinding of the wire rope body 6 wound on the take-up roller 5. This allows for the adjustment of the height of the hook 7. The anti-detachment body 702 extends and retracts on the hook body 701 through the return spring 703, thereby facilitating the closure of the hook body 701 and preventing the hook from detaching during lifting and lowering, making it convenient to use.

After the internal lubrication treatment of the lubrication structure 10, the wire rope body 6 is filtered through the filter oil screen 13 and finally stored inside the recycling box 8, which facilitates the circulating lubrication treatment of the wire rope body 6 and makes it convenient to use. Combination Figure 1 and Figure 4 As shown, the lubrication structure 10 includes a lubrication box 1001, lubrication holes 1002, an oil tank 1003, an upper conveying pipe 1004, a lower conveying pipe 1005, and lubrication rollers 1006. Lubrication holes 1002 are installed and connected to both ends of the lubrication box 1001. A wire rope body 6 is threaded through the interior of each lubrication hole 1002. The oil tank 1003 is bolted to the upper end of the lubrication box 1001. The upper conveying pipe 1004 is arrayed and threaded through the upper surface of the oil tank 1003. Lubrication rollers 1006 are rotatably arrayed inside the lubrication box 1001. The lower conveying pipe 1005 is located at the upper end of each lubrication roller 1006. Each individual lubrication roller 1006 is tightly fitted to the outer surface of the wire rope body 6. A circulation structure is formed between the lubrication box 1001, the oil pipe 12, and the recovery box 8, and the oil pipe 12 is a flexible telescopic hose. The structure features a lower conveying pipe 1005 and an upper conveying pipe 1004 arranged vertically in a corresponding manner, with the upper conveying pipe 1004, lower conveying pipe 1005, and lubrication roller 1006 forming a connected structure. The lubrication roller 1006 has a porous cylindrical structure.

Excess lubricating oil drips from the lower end of the lubrication box 1001 into the recovery box 8 for storage and convenient use. This is the working process of the self-lubricating wire rope gantry crane.
