Passenger boarding equipment

Abstract

The invention provides a boarding bridge comprising a vestibule diaphragm device. The boarding bridge comprises a retractable bridge body passage and the vestibule diaphragm device, wherein the vestibule diaphragm device comprises a door-shaped frame, an abutting frame and a retractable floor; the retractable floor comprises a retractable part positioned at the front end; the abutting frame comprises a rigid frame and a flexible frame, the height of the flexible frame is greater than that of the rigid frame, by utilizing the sliding groove formed in the rigid frame, the rigid frame is matched with a sliding shaft at the outer side part of the floor, so as to realize the movement of the rigid frame up and down for some distance relatively to the floor by virtue of a third actuator, and the flexible frame is not directly connected with the floor layer; a plurality of second actuators are connected between the rigid frame and the flexible frame, and one of the plurality of second actuators is fixedly connected to the rigid frame again in a non-pivotal manner by virtue of a detachable bracket; and distance gauges are respectively arranged on branches on two sides of the flexible frame and the front end of the retractable part. With the utilization of the boarding bridge provided by the utility model, tightness and safety are improved.

Description

technical field [0001] The present invention relates to a passenger boarding device, in particular to a boarding bridge including a bellows device, in particular to a docking frame including a docking frame that can adaptively have a shape conforming to the curvature of the plane surface before docking with the plane boarding bridge. Background technique [0002] Airplane boarding bridge is a piece of airport equipment commonly used by modern passenger aircraft. They are used as the entrance for boarding, allowing passengers to enter the interior of the passenger aircraft from the terminal building. This type of boarding bridge usually has a bellows device at its end, which bridges the space between the boarding bridge and the aircraft, so as to protect boarding personnel from adverse weather conditions. [0003] Patent document CN100355628C discloses a sealing device for aircraft passenger ladders or aircraft boarding bridges, comprising a bellows tensioned above a connect...

Problems solved by technology

The above two documents are still relatively single for the use of laser rangefinders

[0006] Therefore, the boarding bridges in the prior art generally have the following defects: due to the single force point of the energy storage device or the actuator, the flexible frame is difficult to adapt to various aircraft surface curvatures, and the flexibility and sealing are poor; The frame fits closely to the fuselage shell, and the force usually applied is relatively large, which is easy to damage the fuselage shell. In addition, since the energy storage device or actuator usually starts to work after the bellows device touches the fuselage shell, it is easy to cause damage to the fuselage shell due to its own Faults or system errors cause overload, which seriously damages the fuselage shell; there is a lack of real-time detection and alarm devices during the passenger boarding process, posing safety hazards
