ROBOT OF INTERNAL PRESSURE EXPLOSION PROOF, CAPABLE OF USING REDUCER AND A GENERAL MOTOR IN A LINK TYPE SECRET ROOM STRUCTURE

摘要

PURPOSE: A robot of internal pressure explosion proof is provided to communicated a pair of air tight chambers, lay piping and wiring through a hollow shaft in order not to need an expensive hollow motor and a hollow reducer.;CONSTITUTION: A robot of internal pressure explosion proof comprises a base(110), a first arm(120), and a second arm(130). The base includes a first air tight chamber(100a) in the inner space. The first arm includes a second air tight chamber(100b) in the inner space and is rotatably connected to the base. The second arm includes a third air tight chamber in the inner space and is rotatably connected to the first arm. A working tool(T) is rotatably connected to an end part of the second arm. The air tight chamber is rotatably connected through male connection parts(127,137) and a female connection part(113). The male connection part comprises articulated shafts(128,138) and hollow shafts(129,139). The female connection part surrounds both sides of the male connection part and includes shaft insertion holes(114,124) which the articulated shaft and the hollow shaft are inserted.;COPYRIGHT KIPO 2013
