Stress conversion device for inclined shaft pressure steel pipe humping

The utility model relates to a stress conversion device for inclined shaft pressure steel pipe humping, and belongs to the technical field of pressure steel pipe installation. The lifting device comprises a lifting plate, a fixing plate, a locking bolt and a locking nut, the fixing plates are installed on the two sides of the hanging plate, the first clamping groove and the second clamping groove are formed in the hanging plate and the fixing plates and used for being connected with the stiffening ring of the pressure steel pipe in a clamping mode, the fixing plates and the stiffening ring are locked through the locking bolts and the locking nuts, and therefore indirect connection between the shackle and the stiffening ring can be achieved through the device. The problem of uneven stress of the pressure steel pipe in the humping process due to the fact that a shackle is directly connected with the stiffening ring is solved, the potential safety hazard of trolley derailment is eliminated, operation is convenie
