Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1-3, the bearing inner ring lifting appliance comprises a lifting ring 1 and a lifting appliance body 9, wherein a turntable wrench 2 is fixedly welded at the bottom of the lifting ring 1; a screw 3 is arranged in the center of the lifting appliance body 9, the top of the screw 3 is welded and fixed with the turntable wrench 2, a nut 4 and a support frame 5 are sequentially arranged downwards, and the screw 3, the nut 4 and the support frame 5 are in threaded connection; a bulge 10 outside the nut 4 and a force arm group 11 arranged on the support frame 5 are rotatably connected with a support leg 12; supporting legs 8 are fixedly arranged at the bottoms of the supporting legs 12.
In a further technical scheme, the supporting leg 12 consists of an upper supporting leg 6 and an A-shaped supporting leg 7, and a bulge 10 outside the nut 4 is connected with one end of the upper supporting leg 6 in a rotating mode; the other end of the upper supporting leg 6 is rotatably connected with the top of the A-shaped supporting leg 7; the tail end of a force arm group 11 arranged on the support frame 5 is rotatably connected with the tail end of the short side of the A-shaped support leg 7.
According to the further technical scheme, clamping grooves are formed in the contact surfaces of the upper portions of the supporting legs 8 and the bearings, are in a step shape, and are inwards recessed.
In a further technical scheme, the force arm group 11 is formed by oppositely arranging two same force arms on the support frame 5.
In a further technical scheme, the number of force arms of the support frame 5 is at least 3 groups.
Further technical scheme, upper portion supporting leg 6 is the H type.
The working principle is as follows: the lifting appliance is placed in the bearing, the groove depressions of the supporting legs are matched and locked with the inner ring of the bearing by using the turntable wrench, after the completion, the screw is rotated to the supporting frame by using the turntable wrench, the bottom of the screw is mutually abutted against the supporting frame, so that the lifting appliance cannot be contracted, and the lifting appliance and the bearing are lifted to a required position in working time; after the lifting tool is lowered to the position, the turntable wrench is rotated, the supporting legs of the retractable lifting tool are adjusted, and the lifting tool is lifted away from the inside of the bearing, so that the lifting is finished; and (4) stopping the lifting appliance at a fixed position, and waiting for next lifting.
