Improved telescopic type boarding bridge

Abstract

The invention discloses an improved telescopic type boarding bridge, which comprises a telescopic passage device and a walkway device. The telescopic passage device at least consists of an inside passage and an outside passage which are mutually sleeved; a certain bottom space is retained between the inside passage and the outside passage; the walkway device comprises a plurality of floorboards which are connected together; a first end of the walkway device is fixed in the bottom space; and a second end of the walkway device is fixed at the front end or near the front end of the outside passage, and further, the mounting position of the second end is higher than that of the first end and is approximately level to a bottom passage. Compared with the existing boarding bridge, with the adoption of the improved telescopic type boarding bridge, the height of a ground surface of a passage of the passage device can be consistent, further, the hiding of floorboard fixing structures and water drainage structures can be realized, so that the safety performance of a product is improved, and the improved telescopic type boarding bridge is safer and more convenient for passengers to walk; and in addition, the improved telescopic type boarding bridge has a simple and compact structure and a lighter weight, further, the mounting and the fixing of the auxiliary equipment of the boarding bridge cannot be affected, and thus, the improved telescopic type boarding bridge is more reasonable in structure and more mature in design.

Description

technical field

[0001] The invention relates to a boarding bridge, in particular to a telescopic boarding bridge with improved structure. Background technique

[0002] Boarding bridges are widely used in various airport systems, and because the parking position of the aircraft will be deviated, and the size and door position of different aircraft are different, it is usually required that the boarding bridge can be adjusted according to different situations. Adjustment, the telescopic boarding bridge is an adaptation design for this purpose. Its structure mainly includes a telescopic channel device, columns, rotating platform, airport access system, lifting system, drive system and service ladder, among which the movable channel It is composed of at least two channels nested and matched with each other. By changing the relative nesting positions of the two channels, the length of the movable channel can be changed to meet different use requirements.
