Wheel-base-changeable passenger lift vehicle

Abstract

The invention provides a wheel-base-changeable passenger lift vehicle. The wheel-base-changeable passenger lift vehicle mainly comprises a vehicle head, a plurality of wheels, a telescopic chassis, a scissor-shaped frame lifting mechanism, a rotating ladder, a sliding ladder, a transition platform and a butt joint platform. According to the wheel-base-changeable passenger lift vehicle, the telescopic chassis which can move relatively is adopted to guarantee stability of the passenger lift vehicle under the specified load, the telescopic chassis can be in the contraction state when the vehicle is in the stored state or in the running state, and thus the space occupied by the passenger lift vehicle can be reduced. When the vehicle is in the working state, the telescopic chassis can be in the extending state so that it can be guaranteed that the center of the gravity of the overall passenger lift vehicle is still within the safety range, and thus stability and safety of the passenger lift vehicle are improved. The wheel-base-changeable passenger lift vehicle is suitable for boarding of all types of airplanes and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of airport ground special vehicles, in particular to a variable wheelbase passenger elevator vehicle with higher safety, stability and wider applicability. Background technique [0002] With the development of civil aviation, passenger elevators have been used more and more widely, especially in airports with relatively large throughput, the corridor bridges near the plane can no longer meet the status quo, so more and more remote planes need to be used Passenger lift truck for boarding. But along with the continuous increase of aircraft body size, the weak point of existing passenger ladder car shows up gradually, and reason is as follows: 1, structure is simple, and applicable surface is narrow. Most of the current passenger elevator cars are designed for some specific models or a class of small and medium-sized aircraft doors, so the lifting range and application range are relatively narrow. 2. The whee...

Problems solved by technology

However, with the continuous increase of aircraft size, the shortcomings of existing passenger elevator vehicles are gradually emerging. The reasons are as follows: 1. The structure is simple and the applicable area is narrow.

Most of the current passenger elevators are designed for some specific models or a class of small and medium-sized aircraft doors, so the lifting range and application range are relatively narrow

2. The wheelbase of the chassis is not variable

At present, the passenger elevator vehicles are based on the second-class general chassis, and its structure is limited by the original second-class chassis structure. The center of gravity of the body is greatly offset by the height and angle of the passenger elevator car, which affects the boarding car. Stability and passenger safety
