Problems solved by technology
However, the existing lifting mechanisms for auxiliary boarding are all composed of multi-stage scissors and forks, which is not easy to control and will also lead to unstable operation
The scissors and forks are too high, and the lower end needs to be installed on the slide rail of the frame through the rollers. Due to the long slide rails and the existing processing accuracy is not high enough, the rollers will yaw during the rolling process on the slide rails, resulting in the scissors and forks. not running smoothly

The invention discloses a movable lifting type passenger boarding ladder for an airport. The movable lifting type passenger boarding ladder comprises a wheel lifting steering device, a guide rail frame lifting rotating device, a guide rail frame, a lift car device and a boarding platform. The wheel lifting steering device is suitable for overall steering and lifting of the vehicle, and the terrainclearance is adjusted; the guide rail frame can be lifted and rotated on the guide rail frame lifting and rotating device to facilitate transportation; a sliding rail is arranged on the guide rail frame, so that the car device can lift and slide on the sliding rail; and the boarding platform is arranged on the lift car device and can be effectively in butt joint with an airplane hatch.
Description
technical field [0001] The invention relates to an airport passenger boarding device, in particular to an airport mobile lift-type passenger boarding ladder, which is used to increase the safety and comfort of passenger boarding, reduce operator misoperation, and realize the airport mobile boarding ladder Intelligent management. Background technique [0002] There are three types of passenger boarding equipment commonly used in airports at home and abroad: one is a tunnel-type passenger boarding bridge, the other is an ordinary passenger boarding ladder, and the other is a special passenger boarding ladder for passengers with reduced mobility. [0003] The cost of the tunnel-type passenger boarding bridge is relatively high. The price of a large-scale tunnel-type passenger boarding bridge is about 5 million US dollars, and it covers a large area. It can only be applied to the fixed boarding gates of large and medium-sized airports. The fixed boarding gates in the terminal b...
