PURPOSE:To enable the grinding work of a sleeve hose to be performed without causing its damage, by constituting a device such that cores of grinding means and the sleeve hose are not changed during the grinding work, in the case of the device which regenerates damaged internal periphery and periphery of the sleeve hose suitable for connecting iron pipes to each other. CONSTITUTION:Lifting beds 9, 10 are mounted to posts 2... on a base 1, and a pair of moving blocks 25, 26 are respectively screwed to threads 13, 14 of horizontal shafts 11, 12 supported to each lifting bed 9, 10. The both blocks 25, 26 are connected by supporting plates 27, 28, and curved parts of swivel arms 31, 32 are turnably connected to bottom faces of the supporting plates 27, 28 through pins 29, 30. Grinding means 41, 42 comprising motors 37, 38 and buffer plates 39, 40 are mounted to one end of each swivel arm 31, 32, and weights 44, 45 are respectively mounted to the other end. Then a sleeve hose 43 to be regenerated is placed on driving rollers 49 longitudinally and laterally provided on a truck 48, and ground as required while being rotated by straightly advancing each grinding means 41, 42. |
