Ohm open-close type sensor of mine aerial cableway

Abstract

The invention discloses an ohm open-close type sensor of a mine aerial cableway. The ohm open-close type sensor comprises a probe detecting part and a probe positioning part which are movably connected through a hook, wherein the probe detecting part comprises a C-shaped probe shell; a strong magnet and a magnetic sensitive element are arranged in the probe shell; the top of the probe shell is connected with one end of the hook through a screw, and the other end of the hook is connected with the probe positioning part which comprises a concave encoder shell; the concave encoder shell is connected with the hook through a shaft; the recess of the encoder shell is connected with a rotating wheel through a rotating shaft; an encoder installed on anther rotating shaft is arranged in the encoder shell; two synchronous wheels are correspondingly arranged on the rotating shaft and one the same side of the encoder and the rotating wheel and are rotatably connected through a synchronous belt. Compared with the prior art, the ohm open-close type sensor of the mine aerial cableway is stable in work, reliable in performance, high in detecting accuracy, strong in interference resistance, accurate in date, high in practicality, wide in application scope and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to an ohm switchable ohm switch sensor for mine monkey cars with simple structure. Background technique [0002] Coal mine overhead passenger device (commonly known as the monkey car) is a new type of mine inclined or horizontal roadway personnel transportation equipment, mainly composed of a driving part, a passenger part, a rope part, a tail wheel part, a tension part and an electric control system . The running speed of the monkey car traction wire rope is about 0.8-3.0m / s. When the wire rope has problems such as broken wires, wear, and corrosion, if it is not repaired in time, it will cause great safety hazards. When the staff finds obvious defects The steel wire rope will be replaced from time to time, but when there is a slight problem, it is easy to ignore the hidden danger. The safety hazard is relatively large, which greatly affects the normal use of the monkey car. Cont...
