In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a high temperature quenching preapre for an unfavorable turn of events shape combination hoist, includes the plum blossom hoist door type connecting piece of hanging on the plum blossom hanging scaffold, the two bottoms of plum blossom hoist door type connecting piece can be dismantled respectively and be connected with double-end connecting piece, two the lower extreme of double-end connecting piece all can be dismantled and be connected with the lifting hook, two it has fixture to hang between the lifting hook, fixture is including hanging the snap ring of rings and the chucking slender axles work piece on the lifting hook, the rings symmetry is fixed to be set up in the snap ring both sides.
The utility model discloses technical scheme's further improvement lies in: the clamp ring is characterized in that a plurality of positioning pin blocks are symmetrically arranged on the side edge of the clamp ring, a plurality of positioning threaded holes are formed in the positioning pin blocks, and through holes matched with the positioning threaded holes are formed in the clamp ring.
Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:
1. the utility model adopts the multi-structure assembled lifting appliance connected by the pin, the matching among the multi-structure is good, the high-temperature heating and cooling of the slender shaft workpiece are ensured to be in a free vertical state, the top of the clamping ring groove of the slender shaft workpiece is evenly stressed, and the bending deformation of the quenching workpiece caused by the deformation of the quenching lifting appliance can be better avoided;
2. the combined lifting appliance of the utility model is high temperature resistant, high strength and small deformation in high temperature use;
3. the combined lifting appliance of the utility model does not need welding and flame cutting after charging and discharging, thereby reducing the labor intensity of workers and reducing the environmental protection risk;
4. the combined lifting appliance has more times of repeated use, and the cost loss caused by large consumption of the conventional lifting appliance is saved;
5. the combined lifting appliance of the utility model can meet the quenching and lifting use of workpieces with different diameters by matching with the positioning pin blocks with various specifications, thereby improving the application range of the combined lifting appliance.
