Adjustable airport pickup platform system used for boarding car

Abstract

The invention discloses an adjustable airport pickup platform system used for a boarding car. The system comprises a chassis, a gangway ladder arranged on the chassis, a lifting device arranged on the chassis, a height variation detecting device and a control system, wherein an airport pickup platform is arranged at the upper end of the gangway ladder and used for being docked with a cabin door; the lifting device can abut against one supporting face and can drive the chassis to ascend and descend relative to the supporting face so as to make the airport pickup platform aligned to the cabin door; the height variation detecting device is arranged on the gangway ladder and used for detecting the variation of the height of the cabin door; the control system is connected with the lifting device and the height variation detecting device at the same time. When an aircraft ascends and descends, the height variation detecting device detects the variation of the height of the aircraft and outputs a feedback signal to the control system, and then the control system controls the lifting device to act so as to drive the chassis to ascend and descend. The adjustable airport pickup platform system is simple in structure, convenient to use and low in manufacturing cost.

Description

technical field [0001] The invention relates to a boarding car, in particular to a pick-up platform system for a boarding car. Background technique [0002] The boarding car is an important equipment for connecting the aircraft. The boarding car is mainly composed of a chassis car and a gangway arranged on the chassis car. The gangway is pivoted on the chassis car and equipped with a lifting cylinder to drive the gangway to rotate and lift relative to the chassis car. Normally when connecting to an aircraft, the pick-up platform on the gangway is kept aligned with the cabin door. During the process of passengers getting on and off the plane, the load of the plane changes, which causes the height of the plane to change. In this way, there will be a phenomenon that the height of the pick-up platform does not match the height of the cabin door. The boarding car needs to be adjusted accordingly to make the pick-up platform The platform remains aligned with the cabin door. [...

AI Technical Summary

Problems solved by technology

[0003] There is a height-adjustable boarding car. The height adjustment of the pick-up platform is realized by changing the inclination angle of the gangway. However, it is necessary to ensure that the pedals of the gangway are on the water surface. Changes, so many moving parts are difficult to coordinate, the rigidity and strength of the gangway are not easy to guarantee, the overall structure of the gangway is very complicated, the processing cost is also high, and it is not convenient to use, so the feasibility is not great

There is also a boarding car, the inclination angle of the pick-up platform relative to the gangway pedal can be adjusted, and the front end of the pick-up platform is aligned with the cabin door by adjusting the inclination angle of the pick-up platform relative to the gangway pedal, but when the height of the aircraft changes greatly , the inclination angle of the pick-up platform relative to the gangway pedal will become very large, which will cause inconvenience to the passage of passengers
