The invention discloses a lift force test device and a lift force test method for an elevator speed governor. The device comprises an elevator speed governor rope wheel, a tension wheel, a first rope, a second rope, a first tension sensor, a second tension sensor, a traction mechanism and a control mechanism, wherein the elevator speed governor rope wheel and the tension wheel are respectively mounted on a bearing pedestal through bearings; the elevator speed governor rope wheel and the tension wheel are connected through a first rope closed ring; the second rope is connected with the first rope in a transmission manner; the first tension sensor is connected in series to the first rope; the first tension sensor is used for obtaining tension force of the first rope; the second tension sensor is connected in series to the second tension sensor; the traction mechanism is connected with the second rope in a transmission manner; the control mechanism is electrically connected with the first tension sensor, the second tension sensor and the traction mechanism. The lift force test device can fully simulate an actual use working condition of the elevator speed governor and meet the demands for data acquisition and analysis verification of static and dynamic lift force values of the speed governor in a development design process of the elevator speed governor.
Description
technical field [0001] The invention relates to the technical field of performance testing of an elevator overspeed governor, in particular to a device and method for testing the lifting force of an elevator overspeed governor. Background technique [0002] The elevator speed limiter is an indispensable safety device in the elevator system. The elevator speed limiter can cooperate with the safety gear as a linkage protection device when the elevator is overspeed or out of control. The elevator speed limiter is used as a device for speed response and manipulation of safety gear. The safety gear is a mechanism that forcibly stops the elevator on the guide rail by mechanical action. When the overspeed switch (first action speed) of the elevator speed limiter acts, the elevator safety loop or control loop is cut off to make the electromagnetic brake lose power and brake. For example, if the elevator continues to accelerate downwards, the elevator speed limiter will block the s...
