The explanation of tunnel large caliber steel tube conveyor system operating process:
Shown in accompanying drawing 8, power turn-on main switch and master cock send electricity for motor starter IC, are in " brake " state, movable motor stall, fortune pipe unit transfixion.Not do not carrying out " advancing " or " retreating ", or when carrying out " risings " or " declines " and operating, movable motor is all stalls also, transport the pipe unit transfixion, promptly are in " brake " state.After the fortune pipe unit loads and goes up steel pipe G, by movable motor M
1Drive, enter the tunnel from the portal.When " advancing " state, retreat if desired, must switch to " resetting ", carry out again " retreating "; Equally, when " retreating " state, advance if desired, must switch to " resetting ", carry out again " advancing ".When " advancing " or " retreating " state, turn left available lever operated steer motor M if desired
2Carry out " left-hand rotation "; When " left-hand rotation " state, turn right if desired, current left-hand rotation " must be resetted ", and then carry out " right-hand rotation ", vice versa.The fortune pipe unit is " putting in place " when arriving the desired location, stops " advancing " or " retreating ", movable motor M
1Be " brake " state.This moment two hydraulic electric motor M
3, M
4Drive two oil pump work, make two hydraulic ram actions, stinger rising (unloading pipe); Unload pipe and finish, hydraulic ram action, stinger decline (return).Movable motor M
1Start once more, the fortune pipe unit " is advanced " or " retreating ", final " withdrawing from the tunnel " loads and transports next root steel pipe again.
