WALK MOVING DEVICE FOR TUBE PLATE

PROBLEM TO BE SOLVED: To provide a walk moving device for tube plates which is used in a water chamber of a heat exchanger, facilitates carrying-in and -out with compacted outside configuration, and enhances the working effectiveness by increasing the walk moving speed. SOLUTION: A walk moving device 1 moving on one side of a tube plate where holes for mounting heat conducting pipes are bored in a certain arrangement is composed of a pair of clamp devices 10 and 20 each equipped with at least two clamp shafts 13 and 23 capable of emerging and retracting and also expansion on the mounting plates 11 and 21 confronting the tube plate, a telescopic mechanism 30 interposed between the clamping devices 10 and 20 to cause their approaching and separating to/from each other, and a revolving mechanism and bending mechanism which are interposed between the telescopic mechanism 30 and clamp devices 10 and 20 and which rotate and tilt the telescopic mechanism.
