Problems solved by technology

[0007] But above-mentioned prior art scheme also has some defects, such as the reflection of chain fracture is hysteresis, and the driving device of normal operation can't point out the situation of chain fracture; large, thereby increasing the follow-up maintenance cost; and although detection devices and alarm devices are installed, there are no further measures to deal with broken chains, so it is impossible to avoid equipment damage caused by broken chains and accidents that even endanger the safety of personnel

Abstract

The invention discloses a braking device and a boarding bridge. The braking device comprises a locking member and at least one set of braking assembly. The locking member is fixedly installed on a passage of the boarding bridge; each set of braking assembly comprises a swing member which is rotationally installed on a pick-up port, a swing wheel which is installed on the swing member and an elastic member; the elastic member is provided with pre-tightening force; under normal working state of a driving belt, abutting force is formed by the swing wheel matched with the outer side of the drivingbelt for balancing the pre-tightening force of the elastic member; when the length of the driving belt between a follow-up pulley and a driving wheel exceeds a set value or the driving belt is fractured; the pre-tightening force of the elastic member rotates the swing member to the direction of the locking member and makes the swing member matched with the locking member to achieve braking.

Description

technical field [0001] The invention relates to a braking device for a boarding bridge and a boarding bridge. Background technique [0002] The pick-up port is the part that is in direct contact with the aircraft door when the boarding bridge and the aircraft are docked. The port is pivotally connected to the aisle of the aerobridge and driven by a rotary drive to rotate around the aisle round table of the aerobridge. [0003] The existing rotating drive device for the machine port is composed of a drive motor, a chain, a sprocket, etc., wherein the drive motor is fixedly installed on the machine port, and the drive sprocket is connected to the output shaft of the drive motor through a suitable reduction mechanism. The chain is fixed on the aisle of the boarding bridge, and in particular, on the outer periphery of the aisle. The chain meshes with the drive sprocket and with the appropriate intermediate sprocket. When working, the driving motor rotates, so that the driving...
