Boarding bridge and aircraft door protecting device thereof

Abstract

The invention provides an aircraft door protecting device for a boarding bridge. The aircraft door protecting device comprises a detecting switch, a trigger plate, an elastic part and a control systemof the boarding bridge. The trigger plate is arranged on a floor of the boarding bridge and can swing with respect to the floor. The elastic part is connected with the trigger plate and elastically supports the trigger plate so as to form an included angle between the trigger plate and the floor. The detecting switch is electrically connected with the control system of the boarding bridge. When an aircraft door is close to the boarding bridge, the trigger plate can be in contact with the aircraft door, the trigger plate swings towards the floor under the extruding force of the aircraft door so as to trigger the detection switch, the control system receives a signal sent by the detection switch and then controls the boarding bridge to descend so as to avoid collision with the aircraft door. The aircraft door protecting device is simple in structure, a rubber sensing strip is omitted, the reliability reduction problem caused by rubber ageing is avoided, and meanwhile the cost is reduced.

Description

technical field [0001] The invention relates to an airport boarding bridge, in particular to an aircraft door protection device for the boarding bridge. Background technique [0002] The boarding bridge is used to enable passengers to board the plane from the waiting hall. One end of the boarding bridge is connected to the waiting hall, and the other end is docked with the aircraft door. In order to prevent the boarding bridge from colliding with the aircraft door, induction strips are generally used on the boarding bridge to protect the aircraft door, that is, a safety edge is installed on the floor of the boarding bridge, which includes the mounting seat and the sensing strip above the mounting seat. , when the door touches the sensor bar, the safety edge is triggered, and after the safety edge trigger signal is input to the boarding bridge control system, the control system controls the boarding bridge to descend according to a predetermined program, thereby protecting th...

AI Technical Summary

Problems solved by technology

There is a certain distance between the sensor strip and the mounting seat, which is a buffer stroke, which is used to protect the aircraft door from damage before the boarding bridge descends, but the effective stroke of the safety edge is small, and the safety margin is insufficient, and the safety edge shell It is a flexible rubber material, and the rubber material is easy to age and crack and fall off after repeated use. When the rubber breaks or falls off, it is easy to cause the switch to malfunction or fail to operate, thus endangering the safety of the aircraft. In addition, In addition, the cost of security edge is usually relatively high

[0003] In addition, there are currently airbag-inductive aircraft door protection devices and parallelogram-type four-bar linkage-type aircraft door protection devices. The problem is that the airbag-inductive rubber airbag is easily deformed after being squeezed repeatedly by the aircraft door or other objects. , the airbag installation is easy to fall off, and the service life is short. In addition, the parallelogram four-link aircraft door protection device has a complicated structure
