Embodiment Construction
[0015] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] Such as Figure 1-3 Shown, a kind of elevator hoisting wire rope skidding detection device, it comprises the hoisting driving mechanism 3 that is arranged in the elevator shaft, car 1, detection component 5, intermediate relay, time relay, control system 6, alarm, hoisting driving mechanism 3 and The car 1 is fixedly connected, and the lifting drive mechanism includes a main drive device and a deflector wheel arranged in the elevator shaft. A steel wire rope 2 is wound around the main drive device and the deflector wheel. One end of the steel wire rope 2 is suspended from the car 1, and the other end is A counterweight 4 is suspended; the detection assembly 5 is arranged directly above the driving wheel of the main driving devic...

The invention discloses an elevator lifting steel cable slip detecting device. The elevator lifting steel cable slip detecting device comprises a lift driving mechanism, an elevator car, a detecting component, an intermediate relay, a time relay, a control system and an alarming machine, wherein the lift driving mechanism, the elevator car, the detecting component, the intermediate relay, the timerelay, the control system and the alarming machine are arranged inside an elevator shaft; the lift driving mechanism is fixedly connected with the elevator car and comprises a main driving device andan offset guide wheel which are arranged inside the elevator shaft. By adopting a general controller, the elevator lifting steel cable slip detecting device disclosed by the invention realizes steelcable slip detection, has simple circuits and is low in fault rate, stable and reliable in running and good in using effect. Detection switches are used in a pared manner in order to effectively prevent the occurrence of the phenomenon that an iron block just approaches to the detection switches in a slip process, so the accuracy of the steel cable slip detection is improved. According to the elevator lifting steel cable slip detecting device disclosed by the invention, the detection switches adopt Hall detection switches, capacitance type detection switches or a photoelectric detection switches; each detection switch has the characteristics of no contact point, low power consumption, long service life, high response frequency and the like, can reliably work under various severe environments and is accurate in fault alarming signal and small in signal interference.
Description
Technical field: [0001] The invention relates to the technical field of elevator detection, in particular to an elevator hoisting wire rope slip detection device. Background technique: [0002] The composition of the elevator, as we all know, one end of the main wire rope suspended on the pulley in the shape of a bucket is connected to the car, and the other end is connected to the balance weight. The mutual friction force makes the car lift up and down. However, when the frictional force decreases due to wear of the pulley and the main wire rope, accidents may occur due to sliding of the pulley and the main wire rope. In order to prevent such accidents before they happen, inspectors should regularly measure the amount of slippage between the pulley and the main wire rope. The usual measurement method is to stop the car at any floor (except for the lowest floor where the pulley is located in the well), mark the pulley and the main wire rope respectively, determine the refe...
