A plurality of rib plates are uniformly distributed on the outer circular surface of the screw cylinder, and the rib plates are in full-welding connection with the screw cylinder, the bearing plate and the hanging ring A.

The bottom equipartition of loading board is equipped with three or three more component hoisting assemblies.

The component force hoisting assembly comprises a chain and a lifting hook, the upper end of the chain is detachably connected with the bearing plate through a shackle and a lifting ring B, and the lifting hook is connected with the lower end of the chain through the shackle.

The lifting ring B is sleeved with a nut, and the nut is welded on the bearing plate.

The anti-swing part is an ear plate, and a hanging hole is formed in the ear plate.

The beneficial effects of the utility model reside in that: after the hoisting work of the large tank body is finished, the lifting hook is hung on the ear plate, so that the risk that the lifting hook collides equipment or workers under the inertia effect of a travelling crane is greatly reduced. In addition, the loading board has shelters from the guard action, can avoid lifting by crane the oil stain on the equipment wire rope and drop on one's body the staff or large-scale jar internal, further avoids the oil stain to drop and pollutes jar interior raw materials large-scale jar internal. The lifting appliance has the advantages of simple structure, low manufacturing cost, good strength, high reliability and the like.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of fig. 1 at another viewing angle.

In the figure: the method comprises the following steps of 1-bearing plate, 2-rib plate, 3-barrel, 4-lifting ring A, 5-nut, 6-lifting ring B, 7-chain, 8-lifting hook and 9-anti-swing part.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1 and 2, a hoist, including loading board 1, be equipped with hoisting assembly on loading board 1, the bottom equipartition of loading board 1 is equipped with a plurality of component hoisting assembly, the bottom of loading board 1 is equipped with component hoisting assembly corresponding position and prevents goods of furniture for display rather than for use 9.

The bearing plate 1 is of a disc-shaped structure.

The lifting assembly comprises a screw cylinder 3 and a lifting ring A4, the screw cylinder 3 is fixedly arranged at the central position of the bearing plate 1, and the lifting ring A4 is in threaded connection with the screw cylinder 3.

The hanging ring A4 and the screw barrel 3 are in threaded connection in place and are in full-welding connection.

A plurality of rib plates 2 are uniformly distributed on the outer circular surface of the screw cylinder 3, and the rib plates 2 are fully welded with the screw cylinder 3, the bearing plate 1 and the hanging ring A4. When the bearing plate is used, the number of the rib plates 2 is equal to that of the component force hoisting assemblies, and the positions of the rib plates are in one-to-one correspondence, so that the rib plates 2 are beneficial to improving the bearing capacity of the bearing plate 1 and the connection strength among the bearing plate 1, the screw cylinder 3 and the hanging ring A4.

The bottom of the bearing plate 1 is uniformly provided with three or more component force hoisting assemblies. When the large-scale tank lifting device is used, three or more component force lifting assemblies are uniformly arranged at the bottom of the bearing plate 1, so that the expansion angle of the chain 7 during the lifting of the large-scale tank can be reduced, the decomposition force of the chain 7 in the vertical direction is increased, the decomposition force in the horizontal direction is reduced, and the large-scale tank can be lifted safely and reliably.
