The invention relates to a test machine for a rotary elevator balance compensation chain, which includes a balance compensation chain winding and a hydraulic cylinder. A rubber ring is arranged around the inside of the balance compensation chain winding, and a support plate is arranged inside the rubber ring. The inner side of the support plate is provided with a servo motor, the outer side of the balance compensation chain winding is provided with a balance compensation chain, the top of the balance compensation chain is provided with an angle bending test plate, and the top of the angle bending test plate A lifting rod is provided. The beneficial effects of the present invention are: when the installed balance compensation chain is hooked between the buckle racks through the elevator balance compensation chain cable rack to carry out the traction test, the balance compensation chain in the elevator balance compensation chain cable rack can be passed through Between the upper model frame and the lower model frame, the balance compensation chain is effectively passed between the upper model frame and the lower model frame of different heights, and the balance compensation chain can be tested for non-height tension.
Description
technical field [0001] The invention relates to the technical field of elevator balance compensation chain testing machines, in particular to a rotary elevator balance compensation chain testing machine. Background technique [0002] Elevator balance compensation chain is a balance compensation device set up for the steel wire rope and accompanying cable for the balance traction machine traction of the lift-type manned elevator. During the lifting process of the elevator, one end of the compensation chain is connected to the counterweight, and the other end is suspended from the car. Below, when the elevator rises, the compensation chain rises with the car, and the counterweight side and the steel wire rope group are biased towards the counterweight side, resulting in an unbalanced force, which may also cause the elevator to rush to the top. Therefore, it is necessary to balance the compensation chain of the elevator. to test. [0003] The elevator balance compensation chai...
