Shock absorbing device for boarding bridge

Abstract

An exemplary shock-absorbing device for a boarding bridge is for use with lift columns (200) that support the boarding bridge tunnel (100). The device comprises a first transverse support (310) coupled to the bottom of said lift columns (200), having an extended length in the transverse direction. A second transverse support (320) is installed separately below the first transverse support. An elastic member (330) is coupled between the first and second transverse supports to elastically support said first transverse supports. Dampers (340) are coupled between the first and second transverse supports to absorb residual vibration from said elastic member. First and second driveshafts (361a, 361b) are coupled to fixed positions on opposite sides of the second transverse support to be able to rotate. A drive mechanism (360) generates a motive force to move said tunnel (100) and is equipped with a plurality of wheels (363a) on opposite sides of said first driveshaft and a plurality of wheels (363b) on opposite sides of said second driveshaft.

Description

【Technical field】 [0001] The present invention relates to a shock absorbing device for a boarding bridge, wherein the shock absorbing device for a boarding bridge is configured to achieve stable tunnel motion while stabilizing the weight of the boarding bridge as it is mounted on the supporting boarding bridge Below the lifting struts of the boarding bridge, the boarding bridge is installed to facilitate the passage of passengers between the airport buildings and the passenger aircraft. 【Background technique】 [0002] In general, boarding bridges are installed at airports between airport buildings and passenger aircraft to provide safe and convenient passage for passengers from the airport buildings to the aircraft, while they are protected from various weather conditions or Influence of the external environment; the bridge has a structure that enables passage and compresses the length based on the distance between the building, the aircraft and the position of the aircraft ...

AI Technical Summary

Problems solved by technology

[0005] The corresponding components of this boarding bridge are of high value-added, technically integrated structure, since they are manufactured in dimensions large enough to be able to extend to 40m or more and to a height of 5m or more; therefore, the most important It is important that they operate in a stable manner while being used, transported and stored, because if they are damaged, it not only results in great loss of time and money, but also directly affects passenger safety

[0006] However, in the structure described above, the pair of wheels 35 bears the entire weight transmitted through the lifting strut 30; as the distance between the wheels 35 increases, the wheels 35 can be stably supported and positioned at relatively high the height of the tunnel 10; however, as the distance between the wheels 35 expands, it is difficult to evenly distribute the weight between these two wheels 35 if the tunnel 10 is even slightly inclined

[0007] In addition, the problem is that if the tunnel 10 tilts or shakes even slightly during operation, the vertical shaking of the tunnel 10 is repeated by the rebound of the elastic parts, so that a quick stabilization in a fixed position is not possible
