Embodiment Construction
[0028] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0029] refer to figure 1 with figure 2 , the present invention discloses a steel wire rope broken wire broken strand sensor 10, comprising a detection ring 11, a light beam generating receiver 15, and a conductive transmission member 13. The center of the detection ring 11 can pass through the wire rope 20 . The detection ring 11 is provided with a detection channel 14 surrounding the center of the detection ring. The side wall of the detection channel is opaque, and the detection channel 14 is an opaque channel. A reflective film 112 is formed on the outer surface of the inner ring wall 111 of the detection ring 11 , and the reflective film 112 forms a reflective surface 113 on the inner surface of the inner ring wall 111 .

The invention discloses a wire breaking and strand breaking sensor for a steel wire rope. The wire breaking and strand breaking sensor for the steel wire rope comprises a detection ring, light beam generation receivers and a conductive transmission part, a detection channel surrounding the center of the detection ring is arranged in the detection ring, the center of the detection ring can allow the steel wire rope to pass through, a reflective film is formed on the outer surface of the inner ring wall of the detection ring or the inner ring wall of the detection ring is made of the reflective film, the reflective film forms reflective surfaces on the inner surface of the inner ring wall, the plurality of light beam generation receivers are respectively arranged in the detection channel along the circumferential direction of the detection ring at certain intervals, each light beam generation receiver emits light beams to the reflecting surfaces opposite to the light beam generation receivers and receives the light beams reflected by the reflecting surfaces, and the conductive transmission part is electrically connected with the light beam generation receivers, supplies power to the light beam generation receivers, and transmits light beam signals received by the light beam generation receivers to the outside of the detection ring. Compared with the prior art, wire breakage and strand breakage of the steel wire rope can be detected in time, and safety and accuracy are achieved. The invention further discloses an elevator steel wire rope detection device.
Description
technical field [0001] The invention relates to safety detection, in particular to a steel wire rope broken wire and broken strand sensor and an elevator steel wire rope detection device. Background technique [0002] Most of the current passenger elevators and freight elevators use steel wire ropes for vertical lifting. However, due to frequent wear and tear of the steel wire ropes during use, the wire ropes are broken and the strands are broken. It will lead to safety hazards when using the elevator. If a single broken car is skewed, the broken wire rope will fall out of the groove and be involved in the guide wheel or wrap around the car. This is a serious failure of the elevator. Multiple breaks are likely to cause the car to fall and cause safety ACCIDENT. [0003] With reference to Chinese patent CN201621250882, a wire rope broken strand detection device is disclosed, including a ring detection piece, which is installed on a fixed seat, and a proximity switch is provi...
