Problems solved by technology
The outer diameter of large ring forgings after ring rolling is generally 5.5m to 7.8m, and the weight is 12t to 30t. The existing hoisting device has only three hooks, and the strength of the three hooks is very low during hoisting due to the low strength of the hot ring and the relatively small diameter. Large, under the action of its own gravity, the ring forging will be warped, elliptical and other deformations, which will affect the subsequent processing and cannot be adjusted according to the size of the ring

Embodiment Construction
[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0044] Such as figure 1 , figure 2 and image 3 As shown, the present invention includes a suspension ring 1, a suspension tube 2, a lifting lug 3, a support ring 4, a beam 5, an outer reinforcement rib 6, an inner reinforcement rib 7, an L-shaped hook block 8, a bottom hook 9, a heavy-duty shackle 10, Lifting butterfly buckle 11 and high-strength lifting chain 12; the lifting ring 1, the hanging tube 2 and the lifting lug 3 are welded to form the top lifting lug frame; the supporting ring 4, the beam 5, the outer reinforcing rib 6 and the inner reinforcing rib 7 are passed through Welding forms the middle beam support frame.
[0045] The top lifting lug frame is composed of lifting ring 1, hanging tube 2 and lifting lug 3; the lifting ring 1 is an inverted U-shaped elliptical arc, which is welded and connected with the hanging tube 2 after beveling; the ...

The invention belongs to the field of advanced manufacturing, and particularly relates to a large ring forge piece hot working hoisting device. The device comprises a top lifting lug frame, a middle cross beam supporting frame and a bottom lifting hook. The top lifting lug frame is formed by connecting a lifting ring, a lifting lug and a lifting barrel through welding; the middle cross beam supporting frame is formed by connecting a support ring, a cross beam, an L-shaped hook block and a reinforcing rib through welding; and the bottom lifting hook is used for directly contacting with a ring piece. By using the hoisting device, the ring forge piece can be stressed uniformly in the process of lifting a large ring forge piece after ring rolling and during heat treatment, deformation is avoided under the action of gravity of the ring forge piece, the lifting appliance is stable and does not shake, the product quality is guaranteed, the repair rate of a product is reduced to 3% from original 10%, the production cycle is greatly shortened, and the production cost is saved.
Description
technical field [0001] The invention belongs to the field of ring forging, in particular to a hoisting device for hot processing of large ring forgings. Background technique [0002] To solve the hoisting problem of large ring forgings in the manufacturing process, the thermal processing process of large ring forgings is: steel ingot-heating-forging-heating-billet-heating-ring rolling-heat treatment, this device is mainly used after ring rolling and heat treatment process Use the lifting ring. The outer diameter of large ring forgings after ring rolling is generally 5.5m to 7.8m, and the weight is 12t to 30t. The existing hoisting device has only three hooks, and the three hooks have low strength and relatively small diameter during hoisting. Large, under the action of its own gravity, the ring forging will be warped, elliptical and other deformations, which will affect the subsequent processing and cannot be adjusted according to the size of the ring. Therefore, it is nec...
