Inspecting device
专利汇可以提供Inspecting device专利检索，专利查询，专利分析的服务。并且PURPOSE: To achieve a smaller size of an inspection car and an easier rail installation, by supplying an air pressure into a hollow rail to travel an inspection car while it is stopped at a desired position with a magnet means loaded on the inspection can and an electromagnet provided on the rail.
CONSTITUTION: To move an inspection car 2, an air pressure is supplied into a piping 1 through a motor-operated valve 14-2 or 14-4 to run. The position of the inspection car 12 is detected with a magnetic sensor 13 mounted on a piping 1. To stop the inspection car 2 at a specified place, an electromagnet 10 (10-1W10-3) provided on the piping 1 at an inspection point excites a pole opposite to the surface of a permanent magnet 9 of an inspection car 2 on a command from a control panel 3 to stop the inspection car 2 by an attraction force. Thereafter, an inspection window 11 is opened and a pan head 6 is driven and to photograph a video image in all directions with ITV camera 4. The use of a non-magnetic piping for piping 1 serving as inspection orbit facilitates the installation of a rail and makes it inexpensive along with a simple and smaller mechanism.
