Fixed passenger boarding bridge

The invention relates to a fixed passenger bridge for loading and unloading Unloading of aircraft positioned perpendicular to the airport building with an approximately parallel to the aircraft fuselage over the wing extending bridge part and several on it by 90 ° Staggered staircases, which can be moved in the longitudinal direction of the bridge, with cabins for lateral contact with the aircraft fuselage.

The purpose of such plug-in guests is ticking, getting in and out of passengers, especially in the case of large-capacity aircraft, in the shortest possible time, making it easy for the passenger enable us to travel safely from the aircraft to the terminal building and vice versa and protect it from the effects of the weather, noise, Exhaust gases and the jet of running engines as well as danger from service devices on the apron slit.

One embodiment of a passenger bridge is known in which on both long sides of a cantilever, adjustable in height In the waiting room, two side aisles, adjustable perpendicular to the waiting room and connected to one another via transverse ramps, are arranged are. This passenger bridge, accessible from both side aisles to and from the aircraft, is based on two rail-bound, synchronously driven gantry trolleys and is on the building side Connected to the distribution gallery via a movable and height-adjustable ramp.

In another embodiment, the Pluggastbrüoke consists of a box girder of constant length that is fixed to the apron at the terminal building and about halfway along support pillars is anchored "at the front end of which a telescope tunnel is articulated in such a way that it protrudes from the tunnel Tunnel end rotatable cabin over the wing guided and brought to the aircraft cabin door can be. The two cabin doors located in front of the wing can be telescoped and opened at the sides the height of movable Stumtnelbrüeken served.

A disadvantage of the mentioned design of the movable passenger boarding bridge is that the height-adjustable heavy bridge girder in the event of failure of the lifting mechanism, when braking or careless Maneuvering poses a particular danger to the expensive aircraft. The considerable one is also considered to be disadvantageous Construction costs for trolleys and hoists, the large amount of energy required to move the heavy bridge girder and the large amount of space required the voluminous bridge landing gear on the apron.

Disadvantage of the mentioned design of the fixed passenger boarding bridge Is that it is also a heavy and therefore expensive construction and that it is insufficiently adaptable to the different aircraft models.

The invention is based on the object of an over the wing leading passenger boarding bridge that is simple, space-saving and is designed to save weight, the simultaneous operation several cabin doors also for different sized aircraft models and largely excludes the endangerment of the aircraft in the area from moving bridge parts.

According to the invention, this object is achieved in that on the underside one is held approximately in the middle of two stationary pylons Bridge girder made of truss with a rectangular cross-section

a bridge walkway of about the same length is firmly suspended its long side directed towards the plug-stuff hull several in the height-adjustable stairways open onto the walkways and Guide rails are mounted longitudinally displaceable.

In order to avoid damage to the lift adjustment of the stairways (e.g. Breakage of the drive spindles) sinking and thus a hazard of passengers, plug stuff and, if necessary, ground staff working below the stairs according to the invention provided that the height adjustment each A staircase hinged like a parallelogram on a carriage with one (or more) between the carriage and the roof of the Staircase articulated drivable smooth-running spindle -preferably ball screw spindle- takes place; to the parallel one (or more) synchronously driven self-locking spindle is arranged.

For the permanent closure of the side of the passenger boarding bridge facing the aircraft at every position of the staircase it is provided that rolling or sliding walls are arranged between the longitudinally displaceable staircases.

An embodiment of the invention is shown schematically in the drawing and is described in more detail below:

5 shows a detail of a vertical section

through the transition zone between bridge girders and staircase.

The bridge girder 1 of constant length, which preferably consists of a tubular framework construction, is fixed to the one in advance connected to the anchored pylon 2 and is also suspended from it by several steel cables j5. The bridge girder is on the building side 1 connected via longitudinally displaceable roller or self-aligning bearings. The bridge walkway 4 is just as long as the bridge girder 1 and is suspended below it. Between the bottom of the part of the Brüokerilaufsteges 4 protruding beyond the aircraft wing and the wing that is a maximum of 6.00 m high there is a sufficient safety distance. The bridge walkway 4 accessible from building 5 is sealed off on one side so as to be weathertight. On the long side facing the aircraft to which the longitudinally movable staircases 6a - c are connected, this sealing is preferably done by means of horizontally arranged roll walls 7, which are when moving the stairs 6 unwind or wind up automatically. The staircase 6 is articulated in the manner of a parallelogram on a carriage 8 and is raised or lowered via a lifting drive 9. The stairs, which are also hinged like a parallelogram, remain here horizontal. The raising and lowering of the staircase 6 is preferably carried out with a ball screw 11, the purpose of Protection against falling stairs at Spindelbruoh with one or more synchronously running, self-locking safety spindles 12 is combined. The carriage 8 is on the longitudinal side of the bridge girder 1 facing the aircraft in the running or Guide rails 13 and 14 on roller bearings. One or more of the Main support rollers 15 are driven by the travel drive 16. At the end of the staircase 6 facing the aircraft, the telescopic cabin 17 is also shown in the manner of a parallelogram.

brought. The zieharmonlka-like cabin I7 is preferably via a scissor system arranged on both sides 18 extended and retracted. The telescopic area is dimensioned so large that depending on the fuselage cross-section and Door entry height of the plug-in items of different lengths between the car threshold I9 and the beginning of the flight of stairs 20 can be bridged.

The mooring maneuver is briefly explained below; The plug stuff rolls along its guiding line or its guiding beam approximately parallel to the bridge girder 1 to the stopping point. During the roll-up, all staircases 6 are in waiting position with the cabin completely retracted, with the over the stairwells 6 leading to the wing are raised to the necessary safety distance. After rolling out the Plugzeuges are the stairs 6 each individually in the Move room coordinates and apply them to the aircraft door assigned to them.

The advantages achieved by the invention are in particular that with the least possible space requirement on the apron by using a bridge pylon firmly connected to the apron and with the lowest possible construction weight by using a passenger bridge is created by lattice structures, which universal operation with the greatest possible operational safety made possible by aircraft of different sizes.
