The research scheme and system structure of a main bolt hole cleaning device are put forward,and the basic functions and key technologies of the cleaning device are studied theoretically.An analysis is conducted on the walking status of the cleaning device,the lifting module of cleaning component and positioning drying component.The results show that the device can walk normally without slipping and complete the lifting operation of the lifting module.A new adaptive positioning system is proposed,in which the cleaning device senses the cleaning position through a proximity switch to achieve rough positioning,and the guiding positioning section of the positioning drying cylinder is adopted to achieve precise positioning.The bracket component always provides a radial tensile force,and the frame component tends to move towards the center due to the tensile force.However,due to the action of the side wheels,it will always adhere to the outer circle of the flange,thus achieving complete positioning of the cleaning device.The error after precise positioning is analyzed,and the axis deviation of the cleaning component does not exceed 0.3453 mm,which meets the requirements.The method of limiting and resetting the cleaning brush with spring plate is put forward,and its design parameters are simulated and optimized.The results show that the hole can be cleaned effectively when the thickness of spring plate is 0.4 mm.
