The invention relates to a rotary elevator balance compensation chain testing machine. The machine comprises a balance compensation chain winder and a hydraulic cylinder, a rubber ring is arranged onthe periphery of the interior of the balance compensation chain winder, a supporting plate is arranged in the rubber ring, and a servo motor is arranged on the inner side of the supporting plate. A balance compensation chain is arranged on one side of the outer portion of the balance compensation chain winder, an angle bending test plate is arranged above the balance compensation chain, and a lifting rod is arranged at the top end of the angle bending test plate. The rotary elevator balance compensation chain testing device has the beneficial effects that when the installed balance compensation chain is hung between hanging buckle frames through an elevator balance compensation chain cabling rack for traction force testing, the balance compensation chain in the elevator balance compensation chain cabling rack can penetrate through the space between an upper model frame and a lower model frame, the balance compensation chain can effectively penetrate through the space between the uppermodel frame and the lower model frame at different heights, and non-height stretching detection can be conducted on the balance compensation chain.
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...
