Abstract

The utility model discloses a double-traveling crane lifting device for a dry-type transformer, which comprises a rectangular lifting frame with four frame bodies, wherein a plurality of reinforcing beams which are arranged at intervals are welded and fixed in the frame bodies, a cross-shaped reinforcing piece is welded and fixed between the two reinforcing beams at the middle position, a rotatable lifting ring is arranged below the cross center position of the reinforcing piece, a lower lifting rope is hung at the rotatable lifting ring, four lifting rope tail ends are formed in total by the lower lifting rope, a lower shackle is arranged at the tail end position of the lifting rope, and the lower shackle is used for locking and connecting with a clamp lifting point of the dry-type transformer. The novel lower lifting rope is connected with the lifting frame in a single point mode and is movably connected, and even if two travelling cranes lift out of sync, the two ends of the dry-type transformer are stressed uniformly, and no-load loss is influenced by deformation of the iron core. And after the dry-type transformer is lifted, the dry-type transformer can rotate on the horizontal plane, so that the placing in different places and the loading and delivery requirements are facilitated.

Description

Dry-type transformer double-traveling crane lifting device Technical Field The utility model relates to a hoisting device, in particular to a double-traveling crane hoisting device for a dry-type transformer. Background The existing dry-type transformer double-traveling crane hoisting device adopts a special hoisting tool, and a hoisting tool frame is of a rectangular structure. Four lifting ropes are respectively arranged at four corners above the frame, the total of four lifting ropes are arranged, two lifting ropes at the short side of one side of the rectangular frame are hung on the lifting hook of one travelling crane, and two lifting ropes at the short side of the other side are hung on the lifting hook of the other travelling crane. Four lifting ropes are arranged below the frame, each lifting rope corresponds to a clamp lifting point of the dry-type transformer respectively, the end part of each lifting rope is provided with a shackle, the shackle is locked with the clamp lifting point of the dry-type transformer by utilizing a bolt, the lifting ropes are vertical to the horizontal plane, two travelling cranes hoist simultaneously to hoist the dry-type transformer, if the lifting of the two travelling cranes is asynchronous, single-side pre-stressing can be caused, thus uneven force applied to the clamp of the iron core of the dry-type transformer is caused on two sides, the rectangular iron core is easily deformed into a parallelogram, the iron core joint is enlarged, and no-load loss of the dry-type transformer is affected. Meanwhile, the lifting ropes of the traditional double-crane lifting device of the dry type transformer are respectively hung on two cranes, so that the rotation function of a single crane lifting hook is lost, the crane is difficult to rotate after lifting, and the defects of inconvenience in loading and delivery are caused. Disclosure of utility model In order to solve the defects of the technology, the utility model provides a double-traveling crane lifting device for a dry-type transformer. In order to solve the technical problems, the technical scheme adopted by the utility model is that the double-row vehicle lifting device for the dry type transformer comprises a lifting frame, wherein four side frames of the lifting frame are rectangular, a plurality of reinforcing beams which are arranged at intervals are welded and fixed in the rectangular four side frames, and a cross-shaped reinforcing piece is welded and fixed between two reinforcing beams positioned at the middle position; A rotatable hanging ring is arranged below the cross center position of the reinforcing piece, a lower hanging rope is hung at the rotatable hanging ring, four hanging rope tail ends are formed on the lower hanging rope, a lower shackle is arranged at the tail end position of the hanging rope, and the lower shackle is used for being locked and connected with a clamp hanging point of the dry-type transformer.
