Detailed Description

Specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings so as to be more clearly understood by those skilled in the art.

Examples

As shown in fig. 1, the utility model comprises: a hanging ring 1, wherein the hanging ring is provided with a plurality of steel wire ropes 2, the lower ends of the steel wire ropes are connected with a hanging hook component 3,

as shown in fig. 2, 3 and 4, the hook assembly comprises a lifting lug 31, a cylindrical hanger rod 32 and a hook body 34, wherein the lifting lug is connected to the upper end of the hanger rod, and the circular plate-shaped base 35 is connected to the lower end of the hanger rod; a plurality of pairs of strip-shaped bulges 33 which are outward in the radial direction are uniformly distributed on the suspension rod along the circumferential direction, a plurality of suspension hook bodies are corresponding to the plurality of pairs of strip-shaped bulges one by one, and one end of each suspension hook body is rotatably connected with the lower ends of the strip-shaped bulges through a pin shaft 310; the upper end of the suspender is sleeved with a limit ring 39, the excircle of the suspender is connected with a limit pin 311, and the limit pin is positioned in a groove between the strip-shaped bulges; the hook assembly further comprises a furling mechanism.

Further, as shown in fig. 5 and 6, the furling mechanism includes a furling ring 37 and a manual ring 36, the diameter of the furling ring is slightly larger than that of the base, the manual ring is sleeved on the periphery of the strip-shaped protrusions and connected with the furling ring through a plurality of connecting rods 38, a plurality of limiting protrusions 312 are uniformly arranged on the inner circle of the manual ring, and the limiting protrusions are positioned in the grooves between the strip-shaped protrusions 33 and can move up and down between the limiting rings and the limiting pins.

The utility model discloses a theory of operation:

when the lifting hook is used, the manual ring 36 is pulled upwards, the furling ring 37 furls the lifting hook body 34, the lower end of the lifting hook component 3 is inserted into the through hole of the front end plate of the gearbox and penetrates through the through hole, the manual ring is loosened, the furling ring 37 slides downwards under the action of gravity to be separated from the lifting hook body, and the lifting hook body is unfolded and supported by the base. Inserting a plurality of hook assemblies into the selected through holes one by one according to the mode; then, hoisting is started, at the moment, the four hook bodies of each hook assembly are tightly attached to the bottom surface of the front end plate of the gearbox, the front end plate of the gearbox is stably hoisted, and simultaneously, the formed radius of the opened hook bodies is far larger than that of the through holes, so that the unhooking phenomenon cannot occur; after the end plate at the front end of the gearbox is positioned, the manual ring 36 is pulled upwards again, the lifting hook body 34 is folded by the folding ring 37, and at the moment, the lower end of the lifting hook component 3 can be conveniently pulled out of the through hole.
