Deformation element based on measurement distance

Abstract

The invention discloses a deformation element based on a measurement distance, which comprises a hard frame, a flexible frame and a telescopic floor section, wherein the telescopic floor section extends and contracts in a floor layer by using a first actuator; the height of the flexible frame is greater than that of the hard frame; the hard frame is matched with a sliding shaft at the outer side part of a floor by using a sliding groove formed in the hard frame, and can vertically move for a certain distance relative to the floor by virtue of a third actuator; the flexible frame is not directly connected with the floor layer; a plurality of second actuators are connected between the hard frame and the flexible frame; one of the second actuators is fixedly connected with the hard frame in a non-pivoting manner by virtue of a dismountable support; range finders are arranged at branches on the two sides of the flexible frame and the front end of a telescopic part; and the hard frame of a butting frame is connected with a door-shaped frame of an awning device by a retraction jack and an energy storage device. With the adoption of the butting frame, the sealability and the safety of a boarding bridge are improved.

Description

technical field [0001] The present invention relates to a deformation element based on measuring distance, in particular to a docking frame for an awning device, in particular to a docking frame which can adaptively have a shape conforming to the curvature of the aircraft surface before docking with the aircraft . 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 canopy device at its end, which bridges the space between the boarding bridge and the aircraft, so as to protect the boarding personnel from the influence of bad weather conditions. [0003] Patent document CN100355628C discloses a kind of sealing device of aircraft passenger flight ladder or aircraft boarding bridge, comprises a canopy that is stretched t...

Problems solved by technology

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

[0006] Therefore, the canopy device in the prior art generally has the following defects: due to the single point of application 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 exerted 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 awning device touches the fuselage shell, it is easy to cause damage to the fuselage shell by itself. 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
