Abstract
PURPOSE: To readily replace a pumping tube by connecting to a discharge end of the pumping tube and a concrete transfer pipe, both ends of a short joint pipe which is slidably stuck to a supporting arm pivotting on a pump case.
CONSTITUTION: To replace a worn pumping tube 5, joints 27, 28 are screwed off and a pin P2 is pulled off. A shoft point pipe 9 slidably stuck to a supporting arm 17 pivotting on a pump case 1 is removed from a discharge end 7 of the pumping tube 5 and a concrete tansfer pipe 29. A suction end 6 is removed from a hopper 6. After a pin P1 is off, the supporting arm 17 is turned to incline in fixed location where a pin P1 is inserted through an upper hole 20 and a pin hole 22 meeting with each other. By pulling one end of the pumping tube 5, it can be readily removed from the pump case 1.
