Elevator steel wire rope overspeed detection equipment

Abstract

The invention discloses elevator steel wire rope overspeed detection equipment. The elevator steel wire rope overspeed detection equipment comprises a traction wheel, steel wire ropes, an overspeed detection mechanism, a rope breakage detection mechanism, an abrasion detection mechanism and the like. The overspeed detection mechanism is arranged to obtain pictures of marking sections on the opposite steel wire ropes, according to the time of the upper and lower two marking sections and the distance between the two marking sections, the speed of the steel wire ropes is calculated and obtained,overspeed detection on the steel wire ropes is achieved, detection is convenient, and accuracy is high; the rope breakage detection mechanism is arranged, when the steel wire ropes break, the steel wire ropes are changed from the tensioning state to the loosening state, a first spring shrinks, a tension sensor monitors the spring state change, rope breakage detection on the steel wire ropes is achieved, the structure is simple, and detection is convenient; and the abrasion detection mechanism is arranged, if the steel wire ropes are abraded, rollers downwards move under the effect of a secondspring, a movable plate is driven to downwards move, a distance sensor detects that the distance between a fixed plate and the movable plate is increased, abrasion detection on the steel wire ropes isachieved, and the detection accuracy is high.

Description

Technical field: [0001] The invention belongs to the technical field of elevator detection, and in particular relates to an elevator wire rope overspeed detection device. Background technique: [0002] In modern society, elevators are widely used and are inseparable from people's daily life. They have become ubiquitous equipment for transporting people and goods in multi-storey buildings. Because elevators frequently stop on various floors all day long While in continuous operation, the safety performance of the elevator plays a vital role. The elevator car and the counterweight device are connected by wire ropes, which are driven by the traction machine to move the elevator car in the hoistway. As the main force-bearing and force-transmitting components, the safety performance of the steel wire rope has a great influence on the use of the elevator. [0003] At present, there is no relevant detection device for the elevator wire rope in the elevator safety system. When the ...
