Description
Technical field
The present invention relates to a kind of airstair, relate in particular to a kind of orbit movable airstair being applicable to flight simulator.
Background technology
The flight simulator height with kinematic scheme is higher, needs the special upper and lower simulator of ladder supplemental training personnel, and meanwhile, between simulator moving period, ladder will depart from simulator in time.
Chinese patent literature CN102689695A discloses a kind of airstair, comprise ladder body, described ladder body is made up of railing, square steel tube, tap-tap plate, angle steel and axle sleeve, described axle sleeve is connected with the output shaft of swing-type cylinder by flat key, and the axle head of described output shaft is by baffle plate and bolted; Described swing-type cylinder is arranged on the steel plate of fixed mount, and described output shaft is vertical with described steel plate; Described fixed mount is arranged on the side of equipment, the top of equipment, be positioned at ladder and arrive vertical position place, be fixed with the latching device be made up of proximity switch, locking cylinder, locking pin and locking rack, described proximity switch, locking cylinder, locking pin are arranged on described locking rack successively, and described locking rack is fixed on equipment.Namely in a kind of airstair described in above-mentioned patent documentation, in boarding state, ladder is in bottom, with vertical plane angularly 2A; When ladder needs locking time, ladder reaches after revolving turnback and exports axisymmetric position, and the angle A of the angle A of ladder and output shaft and output shaft and horizontal surface is cancelled out each other, and ladder is vertical in ground after revolving turnback along with output shaft; When ladder rotates approach locking device desired location time, the proximity switch action of latching device, the oil cylinder of locking end stretches out, and the locking pin promoting to coordinate puts in the hole of ladder square steel tube, make ladder can keep motionless in a device, reach the object of locking ladder; When needs get off from equipment, locking cylinder action, locking pin is extracted out, and then oscillating oil cylinder action, ladder rotates to bottom surface, thus can boarding.
A kind of airstair described in above-mentioned patent documentation, existing weak point is: be all fixed mount not on separation instrumentation (body) when the airstair in the prior art uses and after using, therefore, the requirement that airstair departs from time from equipment (body) can not be realized, therefore, this airstair is not suitable for applying on flight simulator.
Chinese patent literature CN2584515Y discloses hand airstair, comprise portable supporting body, the surrounding of described portable carrier is provided with scalable leg symmetrically, terraced body is had above it, the lower end of ladder body is hinged on the rear end of portable supporting body, and have lifting body between front end and portable supporting body, described portable supporting body contains underframe, this underframe is tabular, is provided with roller bottom it.Namely in the hand airstair described in above-mentioned patent documentation, when it is desired to be used, be adjusted to and be applicable to highly before only this airstair need being pushed into equipment, directly pushed away away after finishing using.
Hand airstair described in above-mentioned patent documentation, there is following shortcoming: this hand airstair is only be provided with the stop mechanism that pair roller carries out braking, although roller can not roll under the effect of stop mechanism, but under the effect of external force, due to roller and ground contact surface little, friction force is little, whole airstair forward slip is easily made to bump against body or offseting slip body is backward separated, thus cause boarding person frighten or slip, easily there is contingency, simultaneously during hand push airstair, be not easy to hold registration ladder whether to aim at the boarding gate on aircraft, also be not easy to hold airstair, be easy to cross because of forward displacement and bump against infringement aircraft side walls caused to aircraft.
Summary of the invention
For this reason, technical matters to be solved by this invention is airstair of the prior art in use, and can not be completely fixed relative to ground, easily shake, safety factor is low, and is easy to aircraft and collides; And then provide one to be applicable to flight simulator, can be completely fixed relative to ground in use, the orbit movable airstair that safety factor is high.
For solving the problems of the technologies described above, a kind of orbit movable airstair of the present invention, comprises ladder, for supporting the supporting component of described ladder, being arranged on the roller bottom described supporting component, also comprising
