Design And Research Of Lightweight Negative Pressure Wall-climbing Robot

There are usually some special places in the construction industry,which often require us to carry out regular safety inspection and quality inspection,in order to eliminate potential safety risks.At present,these works are mainly done by manual hand-held monitoring equipment and detection equipment.Manual work has high labor intensity and low work efficiency.Therefore,we need to study a wall-climbing robot that can replace the manual carrying of special equipment for operation.this subject designs a lightweight negative pressure wall-climbing robot for some safety inspection and quality inspection issues in the construction industry.The wall-climbing robot is used as the motion carrier and equipped with special equipment to replace manual operations.Three-dimensional modeling,simulation analysis and experimental verification are used as the way to carry out the subject research.First,according to the overall design requirements of the wall-climbing robot,the overall technical scheme of the system is proposed.The mechanical structure of the wall-climbing robot is designed with five parts: the adsorption mechanism,the moving mechanism,the sealing device,the noise reduction device,and the overall structure as the main body.Then use Fluent to simulate the centrifugal fan with fluid mechanics to study the internal air flow characteristics of the centrifugal fan when it is working.Subsequently,the wall-climbing robot control system is designed.For the hardware part of the control system,STM series single-chip microcomputer(model STM32F103RCT6)is used as the main control chip of the control system,and other module hardware circuits are designed around the main control chip.For the control system software,the debugging of the control board of the lower computer is compiled and completed on the Keil u Vision5 software,and the interface design of the upper computer is completed on the VS2013 software.The hardware part and the software part are combined to form a complete control system.Finally,the prototype of the negative-pressure wall-climbing robot was completed,and an experimental test system was built to test the wall-climbing robot to verify the overall feasibility of the designed negative-pressure wall-climbing robot.the test results comes from the experimental show that the negative pressure climbing robot maneuvering performance good,wall adaptive performance is strong,can in a variety of flexible wall between mobile.Moreover,it has stable adsorption and a certain load capacity,which meets the overall design requirements of the wall-climbing robot,and can be used as a moving carrier carrying equipment for operations.The research in this paper provides theoretical support and technical reference for the design and improvement of negative pressure wall-climbing robot.
