Technical Field

[0001] The utility model relates to the technical field of electric hoists, in particular to a hanging structure of an electric hoist. Background Art

[0002] Electric hoist is a special lifting equipment installed on overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places. The electric hoist has a compact structure, and the motor axis is perpendicular to the drum axis. The electric hoist adopts a worm gear transmission device. Its disadvantages are: large length and width, bulky structure, low mechanical efficiency, and difficult processing. When the electric hoist is hung with the goods, the goods are mainly lifted by hooks.

[0003] Prior art such as the utility model with publication number CN217650715U discloses a hanging structure of an electric hoist, comprising a fixed block, wherein the side walls on either side of the fixed block are penetrated and slidably connected with a sliding rod, and the outer wall on either side of the sliding rod is fixedly connected with a fixing mechanism; the fixing mechanism is used to form a closed fixing ring at the hook on the electric hoist, so as to ensure that the goods will not fall off during the transportation process, and the fixing mechanism comprises a moving hook, and the moving hook is arranged in an L shape, and the side wall of the moving hook away from the fixed block is penetrated and slidably connected with a handle, and the handle is located in the moving hook and fixedly connected with the moving block at one end, and any two sides of the moving block The side walls are symmetrically fixed with connecting shafts near the bottom, and the two connecting shafts are fixedly connected with moving rods at one end away from the moving block. The utility model can ensure that the goods will not be unhooked during the transportation process by arranging a fixing mechanism, and the simple operation method effectively improves the efficiency of installation and disassembly, and solves the problem that if the goods swing greatly during transportation, they may fall off the hook on the electric hoist, threatening the life of the workers under the goods. If the swing block is used to block it, the spring reset mechanism of the swing block will age after being used for too long, making it impossible to effectively fix it, which will affect the efficiency of installation and disassembly.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] When the lifting device is used, the rope of the cargo to be lifted is hung on the hook body, and the electric hoist drives the hook body to rise through the sling body to lift the cargo. By setting a protective device, when the rope is hung on the hook body, the rope will be pressed on the support plate and the sliding sleeve, pushing the clamping rod spring to be stressed and rotating the pressure plate, and the pressure plate can clamp the rope. After clamping, the clamping rod is released, and the spring drives the push rod to move into the slot on the surface of the support plate.
