LEVELING MECHANISM FOR PASSENGER BOARDING BRIDGE, AND PASSENGER BOARDING BRIDGE
A leveling mechanism for a passenger boarding bridge, and a passenger boarding bridge. The leveling mechanism for a passenger boarding bridge is mounted on a passenger boarding bridge (100), and comprises: a four-bar linkage mechanism and a preload apparatus. The four-bar linkage mechanism comprises a mounting base (2) which can be fixedly mounted on the passenger boarding bridge (100). One of the other three bars of the four-bar linkage mechanism extends outwards, and a leveling wheel (7) and a first detection switch (6) are mounted at the end of the bar. The first detection switch (6) is used for detecting the vertical displacement of the leveling wheel (7) on an aircraft body (500). The preload apparatus has a preload. One end of the preload apparatus is connected to the four-bar linkage mechanism, and the other end threrof is connected to the mounting base (2). The preload apparatus has a preload to make the leveling wheel (7) maintain a tendency of extending outwards. The leveling mechanism for a passenger boarding bridge has high test precision and can work reliably.
