Problems solved by technology

Different from the traditional traction wire rope, the steel core in the center of the composite steel belt is covered with a layer of non-metallic cladding layer. During the operation of the elevator system, especially when running on the rotating parts, the internal The steel core will be bent first, and then stretched into a straight line again. During the long-term running time, it is difficult to detect with the naked eye whether there are broken wires or broken strands in the internal steel core.

Abstract

The invention discloses a detection device for a composite steel belt of an elevator, comprising a first electric connector (2), a second electric connector (3) and electric signal analytical equipment (4), wherein the first electric connector (2) is electrically connected respectively with the head ends of steel cores (11) in the composite steel belt (1), the second electric connector (3) is electrically connected respectively with the tail ends of the steel cores (11), the electric signal analytical equipment (4) is connected with the second electric connector (3), all the steel cores (11) in the composite steel belt (1) are electrically connected with the first electric connector (2) and the second electric connector (3) to form a detection circuit, two ends of the detection circuit are respectively electrically connected with two connecting contacts arranged on the second electric connector (3), and at least a pair of detection contacts are arranged on the electric signal analytical equipment (4) and are to be electrically connected with the two connecting contacts of the second electric connector (3). The detection device for the composite steel belt of the elevator has simple results and convenient installation, can rapidly detect the composite steel belt of the elevator, and judges the degree of wear of the steel cores in the composite steel belt to remove failure risk in advance.

Description

technical field [0001] The invention relates to elevator traction components, in particular to an elevator composite steel belt detection device. Background technique [0002] In many cases, modern elevator systems use composite steel belts as transmission components. Composite steel belts mainly include multi-strand steel cores and non-metallic wrapping layers wrapped around the steel cores. Composite steel belts have the advantages of light weight, small bending radius, and It has the characteristics of low noise and other characteristics, and it does not need regular lubrication. Different from the traditional traction wire rope, the steel core in the center of the composite steel belt is covered with a layer of non-metallic cladding layer. During the operation of the elevator system, especially when running on the rotating parts, the internal The steel core will be bent first, and then stretched into a straight state again. During the long-term running time, it is diffi...
