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 chain breakage, so it is impossible to avoid equipment damage caused by chain breakage and accidents that even endanger the safety of personnel

Embodiment approach

[0043] Such as Figure 1A As shown, an embodiment of the boarding bridge of the present invention includes a boarding bridge channel 200 and an airport pick-up port 100. Wherein the end of the boarding bridge channel 200 is provided with a channel round platform 210 . The port 100 includes a rack 110. The frame 110 is equipped with a rotary drive device 120 that can drive the machine gate 100 to rotate relative to the boarding bridge passage 200.

[0044] Such as Figure 1B with Figure 1C As shown, the rotary drive device 120 includes a drive motor 1, a drive sprocket 2, a drive chain 5 and two follower sprocket shafts 30. Wherein, the drive motor 1 is installed on the frame 110 of the machine interface 100, and the output shaft of the drive motor 1 is connected with the drive sprocket 2 to drive the drive sprocket 2 to rotate. The follower sprocket shaft 30 is fixed on the frame 110 of the port 100, and the follower sprocket 3 is freely rotatably arranged on the follower...

Abstract

The invention discloses a braking device and a boarding bridge. The brake device includes a lock piece and at least one set of brake components. The locking part is fixedly installed on the passageway of the boarding bridge; each brake assembly includes a swinging part rotatably installed on the machine port, a swinging wheel mounted on the swinging part and an elastic part, wherein the elastic part has a preload Under the normal working condition of the transmission belt, the oscillating wheel cooperates with the outside of the transmission belt to form an abutting force, which is used to balance the pre-tightening force of the elastic member. When the length of the transmission belt between the follower wheel and the drive wheel exceeds a set value Or in a fractured state, the pre-tightening force of the elastic member makes the swinging member rotate toward the locking member and locks and cooperates 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] Existing machine-connecting port rotary driving device is made up of driving motor, chain, sprocket etc., and wherein driving motor is fixedly installed on the machine-connecting port, and driving sprocket is connected with the output shaft of driving motor by suitable reduction mechanism. The chains are fixed to the aisle of the boarding bridge, and in particular, to the outer circumference of the apron of the aisle. The chain meshes with the drive sprocket and with the appropriate intermediate sprocket. When working, the drive motor rotates, so th...
