The invention provides a steel wire rope slipping detection device for an elevator traction machine. The steel wire rope slipping detection device comprises an installation base and an elevator control system; a slipping detection mechanism is arranged on the installation base and comprises a photoelectric detection switch, a first tachometer wheel and a second tachometer wheel, wherein the firsttachometer wheel is in friction connection with a traction wheel, and the second tachometer wheel is in friction connection with a steel wire rope; the first tachometer wheel and the second tachometerwheel are coaxially arranged; a first light hole is formed in the first tachometer wheel; a second light hole is formed in the second tachometer wheel; when the second tachometer wheel and the firsttachometer wheel slide relatively to enable the second light hole and the first light hole to coincide, light of the photoelectric detection switch penetrates through the first light hole and the second light hole; a light path of the photoelectric detection switch is conducted; and the elevator control system is connected to the photoelectric detection switch. The steel wire rope slipping detection device has the advantages of being simple in structure, capable of accurately judging whether the steel wire rope slips or not and low in detection cost.
Description
technical field [0001] The invention belongs to the technical field of elevator detection, and in particular relates to an elevator traction machine wire rope slip detection device. Background technique [0002] The slipping of the traction sheave and the wire rope often occurs in the elevator, and there are many reasons for it, such as insufficient traction force, excessive acceleration of the elevator, and too small balance coefficient. When the traction sheave and the wire rope slip, the wear of the wire rope will be accelerated, and when it reaches a certain level, it will pose a greater threat to the stability and safety of the elevator. [0003] In the existing elevator traction machine steel wire rope slip detection technology, most of them use speed measuring devices such as encoders to detect the rotation speed of the traction sheave, and another speed measuring device is used to detect the moving speed of the wire rope alone. Through calculation and comparative ana...
