Elasticity plug 16 being housed, be equipped with sealing ring 29 in the embedded body rear end near in the coupling spindle 33 at splined shaft position.
In the device of the adjusting aperture opening ratio of present embodiment, be provided with pushing tow hydraulic cylinder 18 and appended parts that two covers can pushing tow embedded bodies 11 enter in the embedded hole 9; But also can one or more pushing tow hydraulic cylinders 18 be set within it according to structure situation.
The embedded hand-hole of device of regulating aperture opening ratio also can adopt the polygonal hole of cylindrical hole or rule except that adopting round taper hole, but the geomery of embedded body must be complementary by embedded hole corresponding with it.
Locking mechanism also can adopt locking cap or other form of structure except that adopting the locking eccentric block.Regulate be provided with in the device of aperture opening ratio the programmable logic controller 2 that has locating module ' and to its transmit the code-disc 1 of cutterhead angle displacement signal ' with the displacement transducer that links to each other with it, also have and the programmable logic controller 2 that has locating module ' relay that links and electromagnetic valve or the A.C. contactor of controlling by relay.
The location and the embedded body 11 that wherein are used to control cutterhead 1 have to the control system that embedded hole 9 is embedded in and embedded body withdraws from: the solenoid operated directional valve C1 of code-disc 1 ', the programmable logic controller (PLC) 2 ' that has locating module, control cutter plate driver motor and be used to control its relay J 1, J2, and the relay J 4 and the pipe bending cylinder solenoid operated directional valve C4 of control magnechuck, the relay J 5 and the A.C. contactor JC5 that are used to control it form; Locking after being used for embedded body and embedding and the control system of unblanking have: displacement transducer 3 ', have programmable logic controller (PLC) 2 ', control relay J3, J4, J5, J6, J7, the J8 of locating module, A.C. contactor JC3, JC5, JC6, JC7, JC8 form; Displacement transducer 3 ' is positioned at pushing tow hydraulic cylinder 18.
Code-disc 1 ' is positioned on the axis of cutterhead 1, when needs change aperture opening ratio, code-disc 1 ' has the cutterhead 1 angular displacement signal input that constantly collects in the PLC2 ' of locating module, when it matches with the angular displacement of setting in advance, by relay J 1 control solenoid operated directional valve C1 action, cutter plate driver motor 17 cuts out, cutterhead 1 stops operating, action by pipe bending cylinder solenoid operated directional valve C4 is stretched out pipe bending cylinder 18, pass through the effect of relay J 4 simultaneously, make magnechuck 28 losss of excitation, after embedded body 11 is inserted embedded hole 9, by be contained in displacement transducer 3 in the oil cylinder ' with PLC device 2 ' synergy, can control stepper motor 26 and rotate in good time, drive the eccentric block rotation lock.Displacement transducer in the oil cylinder adopts magnetic hysteresis telescopic displacement sensor in the present invention, but also can according to circumstances select the sensor of other kinds for use.
After finishing the embedding locking of a cone,, return to original state, cutterhead is rotated again, so that repeat above-mentioned location and make another embedded body enter the interior operation of embedded hole by press button 6, relay J 2 control solenoid operated directional valve C1 actions.The aperture opening ratio of the many more shield machines of the embedded body that embedded hole is embedded on the cutterhead is more little, otherwise then big.
When embedded body need withdraw from, earlier pipe bending cylinder solenoid operated directional valve C4 is moved, pipe bending cylinder is stretched out, spline is inserted in the spline housing, release work is carried out in rotation (direction opposite with locking) by stepper motor 26, then by the effect of relay J 8 with A.C. contactor JC8, magnechuck 28 is got, simultaneously by the effect of relay J 8 with A.C. contactor JC8, make pipe bending cylinder solenoid operated directional valve C4 action, with the pipe bending cylinder withdrawal, embedded body is extracted from embedded hole by the suction of magnechuck 28 and the pulling force of pipe bending cylinder.
Insert in the process of spline housing at spline, if the phenomenon that the spline tooth top bumps occurs, then can appear at the situation that the stroke of section pipe bending cylinder sometime no longer increases, this moment magnetic hysteresis telescopic displacement transducer 3 ' will signal pass to the programmable logic controller (PLC) 2 that has locating module ', then control by control relay J7, A.C. contactor JC7, stepper motor is rotated a minute angle, spline is inserted smoothly.
This device should make shield machine stop driving when needs change aperture opening ratio size, with the emptying of the soil of the quarrel in the soil pressure cabin, and by residual quarrel soil in the water jetting at high pressure shower nozzle water spray cleaning embedded hole in embedded body the place ahead, then begins above-mentioned embedding again.
Valve during construction on this device mid-board is to be in closed condition, by the control near switch valve is opened when the pushing tow hydraulic cylinder need stretch out.
