Description
Technical field
The utility model relates to a kind of escalator with the latching device that drives in the wrong direction, and belongs to the escalator technical field.
Background technology
Along with expanding economy, escalator loses nowhere in public places such as market, overpasses.All the more ordinary along with what use, the safety of escalator more and more draws attention.The escalator accident of driving in the wrong direction happens occasionally, cause escalator to drive in the wrong direction by analysis and mainly contain following some reason: the chain fracture that (1) drives, the brake gear of the escalator of producing at present all designs on traction motor or change-speed box, traction motor drives main wheel by change-speed box and rotates, driving wheel drives the escalator axle by flower wheel again and rotates, when chain drive-belt ruptured, brake just can be lost efficacy, and up staircase glides under passenger's weight effect; (2) towing machine is shifted owing to bolt comes loose, and causes chain drive-belt to break away from sprocket wheel, causes up staircase to glide under passenger's weight effect.Escalator also is easy to generate situations such as metal fatigue, safety component be malfunctioning at long-play.We just have like this needs new safety method, guarantees the braking of escalator when the brake gear on traction motor or change-speed box is malfunctioning, avoids the generation of the retrograde accident of escalator.
The utility model content
The purpose of this utility model is, a kind of escalator with the latching device that drives in the wrong direction is provided, it arranges latching device at the escalator axle, when escalator takes place to drive in the wrong direction, latching device will be braked the gear on the escalator axle, avoid escalator to drive in the wrong direction and cause the accident of passenger's injures and deaths.
The technical solution of the utility model: a kind of escalator with the latching device that drives in the wrong direction, comprise traction motor, drive sprocket, driven sprocket, sliding gear and step, drive sprocket is installed on the traction motor, driven sprocket is connected with drive sprocket by messenger chain, driven sprocket is connected by axle drive shaft with sliding gear, sliding gear is connected with step by conduction chain, and the end near sliding gear on driven sprocket and the axle drive shaft that sliding gear is connected also is provided with reverse latching device.End near sliding gear on driven sprocket and axle drive shaft that sliding gear is connected also is provided with reverse latching device, when the emergency case that the generation escalator drives in the wrong direction, reverse latching device is stuck with sliding gear, escalator is stopped, avoiding escalator to drive in the wrong direction and cause the accident of passenger's injures and deaths.
In the escalator of the retrograde latching device of aforesaid this band, reverse latching device comprises brake rod, housing and sensor, and an end of brake rod is connected on the housing, and housing is positioned at the sensor outside, and sensor is located on the axle drive shaft.On the reverse latching device sensor is set, sensor rotates with sliding gear, can monitor the hand of rotation of sliding gear, when retrograde rotation takes place when, sensor will be controlled brake rod by control circuit, and brake rod falls to blocking cliding gear, make the escalator braking.
In the escalator of the retrograde latching device of aforesaid this band, also be provided with projection on the described brake rod.Increase projection at brake rod, projection and wheel tooth spacing equal and opposite in direction, can be safer cliding gear is stuck, make escalator braking.
In the escalator of the retrograde latching device of aforesaid this band, described sensor links to each other with traction motor.Sensor links to each other with traction motor, escalator is being braked the power supply that disconnects traction motor simultaneously.
In the escalator of the retrograde latching device of aforesaid this band, brake rod is " L " type or " door " font.
Compared with prior art, the utility model end near sliding gear on driven sprocket and axle drive shaft that sliding gear is connected also is provided with reverse latching device, when the emergency case that the generation escalator drives in the wrong direction, reverse latching device is stuck with sliding gear, escalator is stopped, avoiding escalator to drive in the wrong direction and cause the accident of passenger's injures and deaths; On the reverse latching device sensor is set, sensor rotates with sliding gear, can monitor the hand of rotation of sliding gear, when retrograde rotation takes place when, sensor will be controlled brake rod by control circuit, and brake rod falls to blocking cliding gear, make the escalator braking; Increase projection at brake rod, projection and wheel tooth spacing equal and opposite in direction, can be safer cliding gear is stuck, make escalator braking; Sensor links to each other with traction motor, escalator is being braked the power supply that disconnects traction motor simultaneously.
