Claims

[Scope of utility model registration request]

In an aircraft inspection workbench adapted to the nose of an aircraft for inspection and maintenance of the aircraft, provided on either the front or rear side of the aircraft inspection workbench,
A pair of left and right steering wheels made of rubber tires whose running angles are controlled independently by steering motors; and a pair of left and right steering wheels, which are provided on the other side of the aircraft inspection platform and whose running speeds are controlled independently by running motors. a pair of running wheels made of rubber tires, and provided at the front and rear of either the left or right side of the aircraft inspection workbench,
a plurality of sensors for detecting guidelines laid on the floor parallel to the parking reference line; and a plurality of sensors provided on the aircraft inspection workbench; a central processing unit that receives the calculation information and outputs calculation information of the running angle of each of the steered wheels and the running speed of each of the steering wheels; a central processing unit that receives the calculation information and converts it into a pulse signal; a positioning controller that independently controls each wheel one by one by inputting input to the corresponding motor via the servo amplifier; and an encoder that integrates the number of rotations of each motor and provides negative feedback to each servo amplifier. 1. A traveling device for an aircraft inspection workbench, comprising: a control device; the traveling device for an aircraft inspection workbench is configured to make the aircraft inspection workbench move so as to fit the nose of the aircraft;
