Carbon fiber telescopic arm for tunnel survey

The front-end arm of the intelligent machinery used for tunnel survey and maintenance is made up of retractable carbon fiber round tubes. During operation, the forearm equipped with detectors and other equipment slowly extends out, and the length is also extended from one meter to nearly three meters. Under the control of the remote control device, the main arm controls the forearm to move up and down and forward and backward. Its slender body is suitable for working in narrow and deep spaces that are inconvenient for the entire machine to enter, effectively expanding the working range of the survey machinery.

 In addition, the temperature difference between the inside and outside of the tunnel is large and the air is relatively humid. The almost zero expansion coefficient and good corrosion resistance of carbon fiber also effectively ensure the operating accuracy of the robotic arm. Compared with metal materials, the advantages are very obvious.
