A port drive structure with self-locking and high integration

Abstract

The invention discloses a self-locking and highly-integrated machine access drive structure, which includes a bracket, a revolving drive device with a self-locking function and several pull rods, one end of the bracket is installed on the boarding bridge through the revolving drive device The lower end of the connecting port is installed on the other end of the bracket; one end of the pull rod is connected to the upper end of the connecting port, and the other end is hinged on the upper end of the boarding bridge, and the swing drive device drives the bracket to rotate. In the present invention, the bracket and the revolving drive device are used to directly support the docking port and drive the docking port to rotate. Lock structure, if the swing driving device fails, the movement of the port relative to the boarding bridge will be locked, avoiding the situation of out-of-control movement after the swing driving device fails. The swing driving device and bracket adopt high-strength structure, which is strong enough High, very low failure rate.

Description

technical field [0001] The invention relates to a drive structure of a machine interface with self-locking and high integration. Background technique [0002] The boarding bridge port is the part where the front end of the boarding bridge connects with the aircraft door. The pick-up port rotates around the control room. The existing driving methods of the boarding bridge connecting the machine port all use the reducer motor to drive the sprocket and the chain to rotate; because the motor has a certain impact inertia force when starting the motor, a certain link in this flexible transmission chain fails. Both will bring great safety hazards to aircraft and personal safety. For example, the driving mode of the existing structure has broken chains, idler sprockets falling off, and shaft breaking of rotating motors during use. For this reason, foreign and domestic boarding bridge standards have added that when the mechanical system fails at the receiving port, there will be no...

The existing driving methods of the boarding bridge connecting the machine port all use the reducer motor to drive the sprocket and the chain to rotate; because the motor has a certain impact inertia force when starting the motor, a certain link in this flexible transmission chain fails. Both will bring great safety hazards to the aircraft and personal safety. For example, the drive mode of the existing structure has broken the chain, the idler sprocket has fallen off, and the shaft of the rotating motor has broken during use.

For this reason, foreign and domestic boarding bridge standards have added that when the mechanical system fails at the receiving port, there will be no uncontrolled movement at the receiving port
