Technical Field
[0001] The utility model relates to the technical field of elevator equipment detection, in particular to a device for measuring the tensioning force of an elevator wire rope. Background Art
[0002] As a convenient and fast means of vertical transportation, elevators are increasingly being used in various occasions. Every day, as many as 1.5 billion people take elevators to travel, so whether it is safe to take elevators has also become a focus of attention. The importance of the elevator traction wire rope as a force-bearing component of the suspension car is self-evident. The tension of the traction wire rope has a great impact on the operation quality of the elevator. When the tension of the wire rope differs greatly, the friction between the wire rope and the traction wheel will be uneven, which may easily cause vibration and noise during the operation of the elevator. Long-term operation with a large difference in tension will easily reduce the service life of the wire rope and the traction wheel. At the same time, faults such as wire rope disorder and de-groove may occur, causing the elevator to stop running, and serious cases may affect the safety of passengers. According to the "Elevator Supervision and Inspection Regulations" promulgated by the General Administration of Quality Supervision, Inspection and Quarantine, "the deviation of the traction rope tension from the average value is not more than 5%". In the prior art, when testing the tension of an elevator wire rope, a spring balance (or a dynamometer) is required to manually pull the elevator wire rope for measurement. The measurement accuracy is low, the device is greatly affected by human factors, and the instrument operation is inconvenient. Utility Model Content
