PURPOSE:To remove clinker safely from heat transfer pipes, by providing an arm supporting member standing upright to a rail inserted in the gaps among a group of heat transfer pipes and moving along the rail, and an arm elevating along the arm supporting member to a cleaning equipment for heat transfer pipes. CONSTITUTION:A rail 1 and a lying arm supporting member 7 are brought into a spot from a manhole 2, and the rail 1 is fixed in a specified position by fitting parts 3. Then an elevator 10 and an arm 11 are fitted to the member 7, and the arm supporting member 7 is set upright by operating a cylinder 14. The arm 11 is to be set nearly in parallel with the arm supporting member 7, with a clamp 8 being closed. The arm supporting member is set upright and is locked. A carriage 6 is moved to a specified position, and then the clamp 8 is opened to fix the arm supporting member 7 in the upright position. A clinker removing work is started by operating the arm 11. The work is taken place to every part on the surface of heat transfer pipes by moving the arm supporting member, by the pivotal movement of an arm 11, and by elevation of an elevator 10. |
