Title:
SAFETY DEVICE FOR BOARDING BRIDGE TRAVELLING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/196789
Kind Code:
A1
Abstract:
A safety device for a boarding bridge travelling mechanism (100), comprising an inner protective shroud mechanism, an outer protective shroud mechanism, a connecting mechanism, and an induction and control mechanism. The inner protective shroud mechanism comprises an inner support (11) and a first universal wheel (12); the inner support (11) surrounds the boarding bridge travelling mechanism (100) and is hingedly connected to the boarding bridge travelling mechanism (100); and the first universal wheel (12) is provided at one side of the inner support (11) and supports the inner support (11). The outer protective shroud mechanism comprises an outer support (21); the outer support (21) is provided at the periphery of the inner support (11), and the lower end of the outer support (21) is lower than that of the inner support (11). The connecting mechanism comprises a first connecting component (31) connected between the inner support (11) and the outer support (21) so that the inner support (11) is hingedly connected to the outer support (21). The induction and control mechanism comprises an induction unit (41). When the boarding bridge travelling mechanism (100) is inclined, the boarding bridge travelling mechanism (100) rotates relative to the inner support (11), but the inner support (11) does not rotate along with the boarding bridge travelling mechanism (100). When the outer support (21) is extruded, the outer support (21) closes to the inner support (11) so as to trigger the induction unit (41).
