APPARATUS TO GUIDE TOOL FOR GAS PIPE WORK

摘要

PURPOSE: A guide device for work tool of gas pipe is provided to improve the efficiency and precision of task by guiding a tip part of an endoscope to a desired direction along the longitudinal direction of a gas pipe. CONSTITUTION: A guide device for work tool of gas pipe comprises a fixing part(1), a movable part(3), a length regulating part(5), a movement distance measure part(7), and a gas shielding part(9). The fixing part is combined with a sandwich valve(V) of the gas pipe line. The movable part moves according to the inside of the fixing part and guides the working tool for the gas pipe line. The length regulating part is installed in the fixing part and movable part. The length regulating part controls the relative distance of the movable part and fixing part. The movement distance measure part is installed in the length regulating part. The movement distance measure part measures the distance of the movable part transmitted from the fixing part'. When the working tool for the gas pipe line is inserted into the inside of the gas pipe line, the gas shielding part secludes the outflow of the gas of the gas pipe line.
