Description

Registration bridge equipment provided with separate channel structure and load bearing structure

The invention relates to a passenger boarding bridge equipment provided for a civil airport, and in particular to a registration bridge provided with a pedestrian passageway separate from a load bearing structure. Background technique

The boarding bridge, which is a necessary accessory for modern large-scale civil airports, is the passage from the airport terminal to the aircraft. In order to adapt to various types of aircraft, it needs to have functions such as rotation, telescope and lift. At the same time, in order to meet the needs of modern passenger transportation, the boarding bridge serves passengers 24/7. It is not only safe and comfortable, but also can shorten the parking time of the aircraft and increase the utilization rate of the aircraft.

In order to achieve the above functions of serving the aircraft, the boarding bridge usually requires the cooperation of various parts to complete the functions of rotation, telescoping and lifting. Generally, the retractable range of the boarding bridge body is required to be between a dozen meters to several tens of meters. It can be seen that the boarding bridge mechanism is long, narrow and complicated. FIG. 1A shows a perspective view of a boarding bridge 10 of the prior art, which has been widely used in airports around the world so far. It is roughly composed of the following parts: a rotating platform 40 connected to the passenger terminal (not shown), fixed to the ground plane by a post 42; a retractable movable channel 12, through the inner channel 12 "Slide in the external communication 12 'to achieve the telescopic function and connect with the rotary platform 40; a port opening mechanism 50 is set at the front end of the movable channel 12 for docking with the doors of various aircrafts, and also includes There is a rotatable dome-type receiving platform 52 and a awning device 54 fixed to the receiving platform 52. Under the control of a control device (not shown), the awning device 54 can be extended outward to adjust A state corresponding to the arc of an aircraft cabin door (not shown); and a lifting device 20 fixed on a traveling system 30, for supporting the entire boarding bridge 10 on the one hand, and for adjusting the movable passage 12 on the other hand Rotate and lift to dock with the aircraft door.

Generally, the span of the boarding bridge's pedestrian bridge can range from 10 to 20 meters. Therefore, it is a basic requirement to be able to support such a long and narrow bridge stably. Figures 1A and 2 show the overall external view of the existing boarding bridge. No matter how the bridge pedestrian walkway part 10 of the boarding bridge changes, the structure of the lifting device 20 with the walking system 30 is basically the same. identical. It is not difficult to see from the figure that, first, the walking system 30 travels on two wheels 32, 32. The disadvantage of this design is that when the walking system 30 turns to any side, the outer wheel 32 or a replacement page (details Article 26) The linear velocity of 32, will be greater than the linear velocity of the inner wheel 32 'or 32, so for a system with only two wheels to walk, it is easy to shake during the turning of the device.

Secondly, the prior art lifting device 20 is adjusted in height by the lifting tubes 22, 22 'which are vertically arranged on both sides of the channel 10. The lifting tubes 22, 22' are fixed to the wheels of the traveling system 30 through a cross beam 24. Shelf 34. Therefore, the fixing method of the prior art lifting device is substantially supported. It can be seen that such a narrow channel structure only depends on the point support of the front end of the channel 10 to support the bridge body. This is not a small problem in itself, because as long as Pedestrians walking from this passage 10 will cause the bridge to sway. In addition, when the bridge body is docked with the aircraft's cabin door, it often moves up and down at the same time under the driving of the walking system; not to mention, in case of an emergency, the walking system will brake suddenly, which will cause the bridge body to The chief vice shakes, causing distortion.

This prior art lifting device 20 with a traveling system 30 has long been accompanied by the above-mentioned insurmountable drawbacks. Therefore, the manufacturer can only make up for the shortcomings caused by the lifting device 20 from the aspect of strengthening the steel structure of the movable channel 12 itself. As shown in FIG. 1A, the movable passageway 12 is a steel structure with a load-bearing design on the outside of the entire passageway, which completely isolates the pedestrian's sight from the outside world. Therefore, when a pedestrian passes through this passageway, there will be a sense of depression. To meet the needs of passengers, manufacturers have made improvements on both sides of the aisle, that is, without changing the steel structure of the bridge body, the side of the aisle is set with transparent glass to form a semi-transparent board as shown in Figure 2. The bridge allows passengers to watch the outside landscape while boarding the aircraft. However, due to the limitation of the steel structure, people cannot achieve the luxury of a fully transparent boarding bridge by replacing the top with transparent glass. It can be seen that this prior art boarding bridge structure is heavy. At the same time, the air-conditioning system provided for the bridge itself is exposed under the bridge, and it does not have a sense of beauty.

In addition, the steel structure design of the above-mentioned channel inevitably leads to a direct connection between the fixing way of the movable channel 12 and the rotating platform 40 as shown in FIG. 1B, and at the same time, it requires a structural member 44 to support it. The extra torque is generated. Correspondingly, it is even more necessary to fix the pillars 42 supporting the rotating platform 40 on the platform through a huge concrete to prevent the bridge body from overturning due to shaking. However, there are always restrictions on underground pile driving around the building. Because the safety of the building must also be taken into account, only 400mm X 400mm X 200mm cement piles can be used. All of the above factors have shown that the boarding bridges of the existing technology are extremely expensive to construct and are not conducive to transportation.

For a long time, people have always wanted to design a boarding bridge device that is lightweight, luxurious, comfortable, and transparent. The boarding bridge can facilitate transportation by simplifying the structure of each part. But many of the shortcomings mentioned above are always unsolved. Summary of the Invention An object of the present invention is to provide a boarding bridge device provided with a channel structure and a load-bearing structure separately.
