Tension test equipment for disc-shaped suspension type porcelain insulator

The invention relates to tension test equipment for a disc-shaped suspension type porcelain insulator. The equipment comprises a left rack, a middle rack and a right rack, the middle rack comprises achain which is arranged on the middle rack and moves in the circumferential direction, a pull rod for the chain to penetrate through, a plurality of hooks which are evenly arranged on the chain deviceat intervals, a hydraulic stretching device which is close to the left rack and used for stretching an insulator, and a jacking inclination device which is adjacent to the right rack and located on the same horizontal line with the right rack. The left rack comprises a first conveying device arranged on the left rack and used for conveying an insulator, a high-pressure water spraying device usedfor cleaning the insulator, a positioning device located on one side of the high-pressure water spraying device and used for rotationally positioning the insulator, and a jacking and throwing-in device arranged on the left rack
