SELF-PROPELLED ELECTRIC TRACTION INSPECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To make a self-propelled electric traction inspection device inspect a trolley line and a catenary wire continuously with the device self-propelling while avoiding obstacles. SOLUTION: The self-propelled electric traction inspection device 1 inspects the state of the damage of the catenary wire W by means of damage detectors 21 and 22 traveling with travel rollers 12 and 13 rolling on the catenary wire W and the remaining diameter of the trolley line T by means of a diameter measuring member 34. The travel distance from a base point is measured by a rotary encoder 30. A sleeve S, which is an obstacle on the catenary wire W, is detected by a rear end detection sensor 32 and a front end detection sensor 32 to carry out inspection whole span by evacuating and restoring the damage detectors 21 and 22. The diameter measuring means 34 measures the remaining diameter of the trolley line accurately moving up and down according to the change in the space between the trolley line T and the catenary wire W. The data from each section is processed by a control device 2 and stored in an external memory such as an IC memory card. An electric traction is inspected smoothly by evacuating and restoring the damage detectors 21 and 22 from and to the catenary wire W and moving up and down the diameter measuring device 34.
