Embodiment Construction
[0046]In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0047] The fatigue life verification system for elevator components provided in the embodiments of the present application can be applied to the field of elevators. It can not only be used to measure whether the elevator wire rope has reached the fatigue life, but also can be used to measure whether the terminal device of the elevator wire rope has reached the fatigue life. Since the termination device includes components such as taper sleeves and wedges, the fatigue life verification system for elevator components provided in the embodiment of the present invention can als...

The invention relates to a fatigue life verification system for an elevator component. The fatigue life verification system comprises a taper sleeve group with a steel wire rope, a sheave group, a power device, a moving platform, a testbed bracket, an electric cabinet, a ranging device and a pressure sensor, wherein the ranging device and the pressure sensor are electrically connected with the electric cabinet; the moving platform and the sheave group are positioned on the testbed bracket the moving platform is positioned above the sheave group, and forms a space with the sheave group; the taper sleeve group is positioned in the space, and is connected onto the sheave group in a winding manner; one end of the taper sleeve group is fixedly connected with the moving platform; the power device is fixed on the testbed bracket; the electric cabinet is electrically connected with the power device; and the pressure sensor is used for measuring the stress of the steel wire rope in the tensioning state and feeding the stress back to the electric cabinet. By use of the system, the elongation of the steel wire rope of the elevator can be measured on the ground, the structure of the system isrelatively simple, and therefore, the verification cost can be greatly reduced.
Description
technical field [0001] The invention relates to the field of engineering technology, in particular to a fatigue life verification system for elevator components. Background technique [0002] Elevator wire ropes and termination devices are commonly used parts of elevators, and the taper sleeve is the most important part of the termination device, and its fatigue life and the fatigue life of the wire rope are related to the safe operation of the elevator. Therefore, it is particularly important to verify the fatigue life of the wire rope and the fatigue life of the taper sleeve. [0003] The traditional verification of the fatigue life of the steel wire rope of the elevator is generally carried out at the bottom of the elevator shaft. By manually measuring the elongation of the steel wire rope of the counterweight on the side opposite to the elevator car, it is determined whether the steel wire rope has reached the fatigue life. The fatigue life of the taper sleeve is genera...
