Walking driving system of air bridge

Abstract

The invention discloses a walking driving system of an air bridge. The walking driving system comprises an air bridge body, and a walking device is arranged on the air bridge body. The walking devicecomprises a wheel carrier, an advancing wheel and a first driving device, the wheel carrier is pivotally arranged on a rack through a first vertical pivot joint shaft, and the advancing wheel is arranged on the wheel carrier and transversely deviates relative to the first pivot joint shaft by a distance. The first driving device is used for driving the advancing wheel to rotate. A locking device capable of being unlocked is further arranged on the air bridge body or the walking device, when the locking device is locked, rotation of the wheel carrier relative to the air bridge body around the first pivot joint shaft can be limited, the first driving device can drive the advancing wheel to rotate at this moment, and then the walking device advances linearly. When the locking device is unlocked, the first driving device can drive the advancing wheel to rotate, and then the wheel carrier rotates around the first pivot joint shaft to achieve steering. According to the walking driving system, the structural components of the air bridge is simplified, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of passenger bridges, in particular to a travel driving system for passenger bridges. Background technique [0002] Passenger bridges are often used for passenger boarding or boarding, etc. Passenger bridges in the prior art generally use two-wheel traveling devices, each traveling wheel is driven by a motor, etc., and the steering motor, swing cylinder, etc. are used to align the wheels The steering is driven by the steering of the frame, or the steering is realized by controlling the rotation direction or speed of each road wheel. The structure is relatively complicated, and the corresponding coordinated control is also relatively difficult. There are many structural components and high cost. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a traveling drive system for a passenger bridge with fewer structural components and lower cost.
