Embodiment Construction
[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0038] figure 1It is a traction elevator system 10 with a suspension ratio of 1:1. The system includes a car 11 and a counterweight 12 corresponding to it. The car 11 and the counterweight 12 are directly connected to the suspension element—the flat tensile assembly 14 connected. The traction pulley 16 of the driving motor 13 drives the movement of the flat stretching assembly 14 to complete the lifting and lowering actions of the elevator. The effect of guide pulley 17 is to keep the distance between car 11 and counterweight 12. The detection device 15 is preferably fixed near the driving motor 13, such as on a motor base or a load-bearing beam. When the elevator goes up or down, the detection device 15 can detect different areas of the passing flat tensile assembly 14 .

The invention discloses a detecting device for a suspension element of an elevator. The suspension element is a flat stretching assembly composed of a plurality of steel wire rope ropes and a wrapping layer; the detecting device comprises a main frame and a plurality of detecting units; each detecting unit comprises a magnetic field exciter and a plurality of magnetic flux detecting element; two electrodes of the magnetic field exciter are close to the flat stretching assembly to magnetize the steel wire core ropes between the two electrodes; each magnetic flux detecting element is positioned between the two electrodes of the magnetic field exciter; the main frame is movably mounted on an elevator system or a fixing assembly in an elevator shaft; the detecting units are movably mounted on the main frame; the main frame and the detecting units can transversely move in the width direction of the flat stretching assembly to enable each steel wire core rope to be aligned to the corresponding at least one magnetic flux detecting element. According to the detecting device for the suspension element of the elevator, when the whole flat stretching assembly offsets or randomly offsets in the width direction, the magnetic flux detecting elements can be kept aligning to the steel wire core ropes in the correspondingly detected flat stretching assembly, and thus the defect inside can be detected accurately.
Description
technical field [0001] The invention relates to lifting equipment, and specifically belongs to a detection device suitable for a suspension component of a lift—a flat tensile component. Background technique [0002] With the development and progress of science and technology, in addition to the form of steel wire ropes, the suspension elements of the elevator system can also use flat tensile components composed of tension elements (such as steel core ropes) and cladding layers, wherein the tension elements extend longitudinally And distributed parallel to the width direction of the flat tensile component, the cladding layer is made of elastic material and wraps the tension element inside it. In this way, under the condition of ensuring the strength, the diameter of the tension element can be reduced, thereby reducing the diameter of the traction pulley of the driving motor in the elevator system, and the reduction of the diameter of the driving pulley can directly reduce the...
