Abstract
The present invention relates to an auxiliary supporting unit for a boarding bridge, a boarding bridge with the same and method for improving stability of boarding bridge. The auxiliary supporting unit includes a leg support which can be driven to extend and retract; and a foot portion attached to one end of the leg support, wherein the foot portion can be supported on the ground when the leg support being extended and can leave the ground when the leg support being retracted.
Claims19
A boarding bridge, comprising:
- a tunnel for carrying passengers;
- an elevation system for changing the height of the tunnel;
- a wheel mechanism for supporting the tunnel and driving the tunnel to extend or retract, provided with
- a beam for supporting the elevation system;
- and
- wheels, attached to the beam through a bearing assembly and being in contact with the ground;
- and
- an auxiliary supporting unit for providing an auxiliary support to the tunnel when the boarding bridge is moving or when the boarding bridge is located at a position, said auxiliary supporting unit being located outside of the wheels and provided with
- two leg supports respectively attached under two ends of the beam and located outside of the wheels, wherein each leg support can be driven to extend and retract;
- and
- two foot portions respectively attached to one end of the leg supports, wherein the foot portions can be supported on the ground when the leg supports are extended and can leave the ground when the leg supports are retracted.
A method for improving stability of a boarding bridge, wherein the boarding bridge is provided with
- a tunnel for carrying passengers;
- an elevation system for changing the height of the tunnel;
- a wheel mechanism for supporting the tunnel and driving the tunnel to extend or retract, provided with
- a beam for supporting the elevation system;
- and
- wheels, attached to the beam through a bearing assembly and being in contact with the ground, wherein the method comprises:
- providing two leg supports which can be driven to extend and retract, said two leg supports being attached under two ends of the beam and located outside of the wheels;
- and
- providing two foot portions, each of which is attached to one end of the respective leg supports, wherein each of the foot portions can be supported on the ground when the respective leg support is extended and can leave the ground when the leg support is retracted;
- detecting a direction and an angle at which the wheel mechanism is slanted when the boarding bridge is moving or when the boarding bridge is located at a position,
- extending one of the two leg supports at a lower end of the beam to drive the corresponding foot portion to be supported on the ground when a detected dimension of the angle is larger than a first predetermined value;
- retracting the one of the two leg supports when the detected dimension of the angle is smaller than a second predetermined value.
