More Information
Summary:The utility model provides a crawler in a tiny tube driven by piezoelectric ceramic and consists of a piezoelectric drive mechanism, a motion drag gear and an elastic posture maintaining mechanism. The crawler is characterized in that the device steadily operates at higher speed in tiny industrial tubes and is suitable for bent pipes with certain curvature and pipe size variation. When arranged on a small operational apparatus, the device constitutes a practical system operating in tiny tubes and can be used for detection and maintenance of corrosions, cracks or mechanical damage and other defects in refrigeration and petrol chemical industries and at nuclear power stations in the place of manual operations, thus improving the work efficiency.
