The invention relates to a fatigability check meter for a movement repeating mechanism of a speed difference self-controller. The fatigability check meter for the movement repeating mechanism of the speed difference self-controller comprises a support frame, the speed difference self-controller, a control box, a fault diagnosis and display mechanism, a dragging system length counting device, a safety rope winding mechanism and a motor and winding mechanism separating device are arranged on the support frame, the control box is respectively electrically connected with the fault diagnosis and display mechanism, the dragging system length counting device, the safety rope winding mechanism and the motor and winding mechanism separating device, a safety rope extends out of the speed difference self-controller and is wound on the safety rope winding mechanism after passing through the fault diagnosis and display mechanism and the dragging system length counting device, the safety rope winding mechanism is connected with the motor and winding mechanism separating device, and the winding mechanism separating is driven to rotate by a motor. By the aid of the fatigability check meter for the movement repeating mechanism of the speed difference self-controller, the fatigability of the speed difference self-controller can be accurately measured, and the safety performance of the speed difference self-controller is greatly improved.
Description
technical field [0001] The invention relates to a fatigue tester for the motion repetition mechanism of a speed difference automatic controller, specifically a test device capable of simulating the reciprocating movement of the safety rope of the speed difference automatic controller, and testing its fatigue performance index, which belongs to the speed difference automatic controller. The technical field of fatigue tester for motion repeating mechanism of differential automatic controller. Background technique [0002] The speed difference automatic controller, also known as the anti-fall device, can quickly brake and lock the falling object within a limited distance. It is suitable for safety protection when the crane is hoisting to prevent the suspended workpiece from accidentally falling. The anti-fatigue performance of the speed difference automatic controller can effectively protect the life safety of the operator and the damage of the suspended workpiece. It is used i...
