Abstract
A running mechanism of a passenger boarding bridge and a control method thereof are provided. The running mechanism includes a beam, two rotary supporting members, and two running wheel sets. Each of the rotary supporting members is pivotally connected to one end of the beam, and connected to the respective running wheel set also. The running mechanism includes four driving devices for driving four running wheels, respectively. The control method is used to provide a matching control for the four running wheels, such that no sliding friction is generated between the running wheels and a ground surface when the passenger boarding bridge is turning.

- A method for controlling a running mechanism of a passenger boarding bridge, wherein the running mechanism comprises;
a beam; two rotary supporting members respectively rotarily connected to underneath portions of the beam adjacent to two ends of the beam; two running wheel sets respectively pivotally connected to the two rotary supporting members at lower ends thereof, each of the running wheel sets comprising a wheel carrier and two running wheels respectively connected to two ends of the wheel carrier; four driving devices adapted to drive four running wheels of the two running wheel sets at lateral sides of the running wheels respectively; a control system comprising a programmable logic controller; and an angle transducer on the rotary supporting member adjacent to the beam, the angle transducer adapted to communicate with the programmable logic controller; the method comprising; submitting a command by an operator to the programmable logic controller to control gradual turning of the running mechanism and to control a speed of a first running wheel; calculating an instantaneous speed of three other running wheels by the programmable logic controller according to a wheel carrier angle of the two running wheel sets acquired by the angle transducer and the speed of the first running wheel, wherein the instantaneous speeds of the three other running wheels match with the speed of the first running wheel, which reduces relative sliding between the four running wheels and a ground surface; and sending commands by the programmable logic controller to control the driving devices of the three other running wheels and to keep the instantaneous speeds of the three running wheels. - View Dependent Claims (25, 26)
