Technical Field

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

[0002] As a part of the elevator traction system, the traction wire rope is an important device of the elevator. The two ends of the traction wire rope are respectively connected to the elevator car and the counterweight, bearing the total weight of both. Therefore, the balance of its tension during operation will affect the normal operation of the entire elevator and the service life of the traction wire rope.

[0003] When testing the tension of elevator wire ropes, it is usually necessary to move the wire rope and judge the tension of the wire rope based on the swing amplitude. However, this type of judgment method mainly relies on the subjective judgment of the operator, which is easily affected by personal experience and feelings, and is not objective and accurate enough. In addition, the swing amplitude is affected by many factors, such as the operator's strength, the length and material of the wire rope, etc. Therefore, it is easy to produce large errors and lead to inaccurate judgments.

[0006] The tubular dynamometer and the left end of the connecting shaft are both equipped with rotating wheels, so that the two rotating wheels are simultaneously attached to the outside of the wire rope;

[0007] A positioning shaft is installed at the center of the front side of the carrying plate, and an operating handle is rotatably connected to the outer side of the positioning shaft so that the operating handle can rotate on the ZY plane;

[0008] The bottom of the operating handle is equipped with a squeezing wheel, so that when the operating handle is rotated, the squeezing wheel squeezes the steel wire rope located between the two rotating wheels.

[0009] Furthermore, the two tube-type dynamometers are both located in the same Z-axis direction.

[0010] Furthermore, the two rotating wheels and the extrusion wheel are located on the same ZY plane.

[0011] Further, a groove is provided on the outer sides of both the runner and the extrusion wheel, so that the steel wire rope can be embedded into the interiors of the runner and the extrusion wheel.

[0013] Further, the cross-sectional shape of the operating handle in the ZY plane is L-shaped.

[0014] Further, the upper runner is connected to the transmission end of the tubular dynamometer.

[0015] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0016] For this elevator steel wire rope tension detector, by attaching the steel wire rope of the elevator to one side of the two runners close to the bearing plate, then rotating the operating handle, the extrusion wheel connected thereto is driven by the operating handle to contact the steel wire rope. Moreover, during the rotation of the operating handle, the steel wire rope is extruded by the extrusion wheel.
