End sequentially passes through the via 3a of guider (this process cable tube P is oriented to by guide roller 12) and slide 3, works as cable tube
When the end of P touches impact switch, impact switch sends a signal to boom hoisting and rotary cylinder 9 ', stops boom hoisting
Only, while rotary cylinder 9 ' works, and blend stop 91 is driven to turn over 90 ° and is stepped down；Three telescopic cylinders 9 are driven, make three to stretch
The piston rod of cylinder 9 stretches out simultaneously, and three pieces of grip blocks 8 clamp cable tube P, unclamp boom hoisting at this time, then driving electricity
Machine 7 makes the output shaft of motor 7 that drive sprocket 6 be driven to rotate, and drive sprocket 6 passes through chain-driving driven sprocket 4 and screw 4 again
Rotation, due to screw 4 and 3 thread fitting of slide, under the action of screw 4, slide 3 moves backward along guide rail 2, by cable tube P
To rear haulage a distance, when slide 3 moves to rear dead-centre position, motor 7 shuts down, the piston of three telescopic cylinders 9
Cylinder bounces back, and three pieces of grip blocks 8 is made to unclamp the clamping to cable tube P, then motor 7 is controlled to invert, and 3 forward slip of slide is made to stop to preceding
Point position, after three pieces of grip blocks 8 clamp cable tube P again, slide 3 moves backward again, so repeatedly, you can realizes line
Cable pipe P is conveyed into tunnel.It after cable tube enters tunnel, is supported by locating rack, and is guided by the locating rack, to next positioning
Frame moves horizontally.First is used to control the front and rear extreme position of slide 3 close to switch A and second close to switch B, when slide 3 is transported
When moving to close at switch, signal is fed back into motor 7 close to switch, motor 7 is made to shut down, such slide 3 also and then stops
Only.
