Technical Field

[0001] The utility model relates to the technical field of elevator production, in particular to an elevator wire rope tension detection device. Background Art

[0002] In order to improve the safety performance of elevators, the steel wire ropes used in elevators need to be tension tested after production. The existing tension detection device usually connects one end of the steel wire rope to a power mechanism and the other end to a dynamometer. The power mechanism pulls one end of the steel wire rope and the dynamometer measures the tension of the steel wire rope.

[0003] When connecting the wire rope, there are usually two ways: one is to directly set lifting rings on one side of the power mechanism and one side of the tension gauge, and tie the wire rope to the lifting rings. In order to ensure the stability of the wire rope binding, the operation is relatively complicated, and the wire rope is easy to be entangled on the lifting rings during the pulling process, and it is difficult to remove; the other is to clamp the mechanism on one side of the power mechanism and one side of the tension gauge, including a fixed block and a movable plate, and drive the movable plate close to the fixed block by bolts, so as to clamp the wire rope between the fixed block and the movable plate. However, the wire rope is not fixed stably in this way, and there is a risk of slipping under the strong pulling force of the power mechanism.

[0004] Therefore, a technical solution is currently needed to solve the technical problems that the ends of the wire ropes are inconvenient to fix, easy to loosen and not firmly fixed during the detection of the wire rope tension. Utility Model Content
