Abstract

The invention provides an internal swelling self-locking hanger and relates to the technical field of hangers. The invention aims to overcome technical problems in hoisting articles. The hanger comprises a hoisting shaft, contact blocks and linkages, wherein the hoisting shaft is a straight shaft, a hoisting ring is fixed at the top of the hoisting shaft, a shaft body and a shaft sleeve of the hoisting shaft are provided with a movable annular slide block, there are three contact blocks axisymmetrically arranged around the axis of the hoisting shaft, there are three linkages, each of which corresponds to one contact block and comprises a long connecting rod and a plurality of short connecting rods, one end of each long connecting rod is in pivot joint with the annular slide block of the hoisting shaft, the other end of each long connecting rod is in pivot joint with the upper part of a corresponding contact block, one end of each short connecting rod is in pivot joint with the lower part of the hoisting shaft with a joint part lower than the annular slide block, the other end of each short connecting rod is in pivot joint with the upper part of a corresponding contact block, and a rubber gasket is fixed on the side surface of each contact block away from the hoisting shaft. The hanger provided in the invention is applicable to hoisting of articles with circular inner bores.

Description

technical field [0001] The invention relates to the spreader technology, in particular to the technology of an internal expansion self-locking spreader. Background technique [0002] In the process of motor manufacturing, it is often necessary to manually move the stator core. The stator core of the motor is barrel-shaped and heavy. The labor intensity of the operator is high, and the stator core is easy to fall, which has the disadvantage of low safety. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide an internally expanding self-locking hoist that can reduce the labor intensity of handling objects with circular inner holes and improve handling safety. [0004] In order to solve the above technical problems, the present invention provides an internally expanding self-locking hoist, which is characterized in that it includes a hoisting shaft, a contact bloc...
