Development and Experiment of Pipeline Anticorrosion Operating Line of Underground Coal Mine
ZHANG Bing-ling;Langfang Polytechnic Institute;
There are a lot of anticorrosive pipes in underground coal mine. It needs special device and tooling to get even, sound and smooth coating on surface of the pipes. The pipe becomes a kind of durable, anticorrosive and antiflaming tubular product. Self-adjusting screw driven wheel set is key driven device of pipeline anticorrosion operating line, which makes the center spacing and oscillation angle of two supporting wheels of operating line realize one touch adjusting too. It is easy to guarantee uniformity of the parameters of each wheel set. Meanwhile, new-added center spacing of the operating line design and latching mechanism of oscillation angle make each wheel set work steadily and reliably and control action of forming even, sound and smooth coating can be realized.
