The invention relates to a hanger for a porcelain shell. The hanger comprises a hanger body; a hoisting structure connected with corresponding hoisting equipment is arranged on the hoisting body; the hoisting body is also provided with a location hole which is positioned on and sleeves the upper part of a corresponding porcelain shell during usage; two support bodies in running fit with the porcelain shell are circumferentially arranged around the periphery of the location hole at an interval and located below the suspender body; a circumferential gap is arranged between the circumference of the two support bodies, and the length of the circumferential gap is greater than the circumferential length of wiring boards on the porcelain shell; an axial gap is arranged between each of the two support bodies and the hanger body to enable rotary screwing-in of a corresponding wiring board along the front and back direction; and the suspender body and / or the support bodies are provided with wiring board limiting mechanisms preventing each wiring board from screwing out from the corresponding axial gap after rotary screwing of the wiring board into the corresponding axial gap and realization of limited cooperation between the wiring board with a corresponding wiring board. The hanger for the porcelain shell provided by the invention can realize reliable hoisting of the porcelain shell.

Description

technical field [0001] The invention relates to a sling used for hoisting a porcelain sleeve in a circuit breaker. Background technique [0002] In the prior art, there is no special lifting tool for hoisting the porcelain bushing in the circuit breaker. The previous lifting tool is to install two lifting rings on the porcelain bushing, and then lift the rings through the hook of the lifting device. During the lifting process , The porcelain sleeve is prone to tilting and shaking, and when the sling of the lifting equipment is loose, the hook is easy to break away from the ring, which makes the lifting process of the porcelain sleeve very difficult and unsafe. Contents of the invention [0003] The object of the present invention is to provide a porcelain sheath hanger with reliable porcelain sheath hoisting. [0004] In order to solve the above problems, the technical solution of the present invention is: [0005] Porcelain sleeve spreader, including the spreader body, ...
