Abstract
The present invention relates to a device for testing drag capacity in emergency work conditions, particularly to a test bench device used for testing emergency work conditions of elevators and testing drag capacity on ground. The device is suitable for testing drag capacity of elevators. The device comprises a main machine, a load motor, a round disc, a steel cable, a round disc main shaft, a regulating bracket and a regulator. The present invention makes use of an emergency work condition workbench to simulate a state in an emergency work condition. Because of friction force existing between a drag wheel and a steel cable, the main machine is driven to run by the steel cable, and simulation loads are added to the main machine by the load motor. When the speed of the main machine is increased to the condition of the rated speed of an elevator, a band brake operates after electricity is turned off. When the speed of the main machine is reduced to stop, the number of rotation times and braking time are recorded so as to obtain the deceleration and the displacement of the main machine and the sliding amount of the steel cable in a corresponding emergency work condition.
