Abstract:
Equipment for removing a resin joint from a pipe fitted with the resin joint, which is characterized by comprising:A fixed plate; a cylinder plate having a cylinder fitted perpendicularly to the outer surface thereof, said cylinder being fitted with a piston rod extending from said cylinder and passing through a hole drilled in the approximately central area of said cylinder plate; a frame on which to mount said fixed plate and said cylinder plate, to connect them with each other by stay shafts at a given space apart and in the positions parallel to each other, and to fix them; and a moving plate disposed between said fixed plate and said cylinder plate, which is fixed to a tip of said piston rod in a manner horizontally moving along said stay shafts as said piston rod moves forward or backward;A lower clamp portion of a V-shape disposed on a upper central part of said cylinder plate to support the pipe portion of the pipe fitted with a resin joint or two; an upper clamp portion of a reverse-V shape disposed right above said lower clamp portion; and a clamp provided with guide holes to make guide shafts pass through said holes in a horizontally movable manner, said clamp being fitted in a vertically movable manner to a tip of the piston rod of a cylinder vertically fixed to a cylinder mount vertically installed on said cylinder plate; andA V-shaped pipe support disposed on an upper central area of said moving plate, which together with said lower clamp portion, holds the pipe portion horizontally; a guide rod vertically disposed in proximity to said pipe support; a lower scraper mount fixed to the inner surface of said moving plate; a lower scraper in the shape of a lower half circle, obtained by horizontally dividing into two halves a circle with a bore slightly larger than the outer diameter of the pipe portion, said lower scraper being provided with blades fitted thereto, which are directed toward the fixed plate; and an upper scraper, being disposed right above said lower scraper and facing it correspondingly and being fitted to an upper scraper mount in a manner vertically moving along the guide rod, said upper scraper mount being fixed to one ends of the guide shafts, with the other ends being allowed to pass slidably through the guide holes of the aforementioned clamp.
