Embodiment Construction
[0062]The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. But those skilled in the art should know that the following examples are not the sole limitation to the technical solution of the present invention, and any equivalent transformation or modification made under the spirit of the technical solution of the present invention should be considered as belonging to the protection of the present invention scope.
[0063] like figure 1 As shown, the guide rail frame lifting swivel device 100 designed by the present invention is fixed on the vehicle frame 200 for installing the guide rail frame 300, and then the boarding car is installed on the guide rail frame 300. The purpose is to make the guide rail frame 300 change height and orientation under the effect of the lifting swivel device 100, so that passengers can log into the car. During installation and use, there are two sets of guide rail frame elevating and...

The invention discloses a guide rail frame lifting and rotating device used for airport mobile boarding ladders. The guide rail frame is used for lifting and rotating the boarding ladder. A four-link hinge mechanism and a lifting power device are provided so that the guide rail frame can be lifted and lowered. The swivel gear and the swivel power unit enable the rail frame to rotate. It solves the problem that the lifting mechanism is too high to be unfavorable for driving in the airport. At the same time, through size optimization, it effectively solves the problem of the two-way screw clamping position.
Description
technical field [0001] The invention relates to an airport mobile boarding ladder device, in particular to a guide rail frame lifting and rotating device for a mobile lift-type passenger boarding ladder, which is used to increase the safety and comfort of passenger boarding and reduce misoperation by operators. Realize the intelligent management of airport mobile boarding ladders. 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 mobile 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...
