Claims

[Scope of utility model registration request]

This is a working station for maintenance and inspection inside the boiler of a boiler such as a thermal power plant that can be raised and lowered in the vertical direction inside the furnace, and an appropriate number of pulleys are installed on both the boiler steel frame above the boiler ceiling wall and inside the arch section below it. Attachment, fixing one end of the hanging wire hung on these pulleys and stretched inside the furnace to an appropriate position on the outer frame that also serves as a scaffold, and wrapping the other end of the hanging wire around the elevator attached to the outer frame, The entire outer frame that also serves as a scaffold is suspended from the pulley via the hanging wire, and a slider that can move linearly in a direction perpendicular to the trolley is provided on a trolley that runs on a rail attached to the inside of the outer frame. Equipped with a positioning mechanism that allows rotation of each torso, horizontal and vertical rotation of the wrist, and twisting of the wrist through the body, and each ash removal device and inspection device are attached to the tip of the wrist mechanism connected to the positioning mechanism. A working station featuring:
