Detailed description of the invention
As shown in Figure 1, this utility model is a kind of anti-block apparatus being applicable to cutter head of shield machine applicator, a plurality of separate foam filling line 1 is included in the foaming system of shield machine, by foam pump 11 in this foam filling line 1, Pressure gauge 12, first check valve 13, effusion meter 14, foam maker 15, foam visor 16, pressure transducer 17, ball valve 18 and the second check valve 19 are sequentially connected in series formation, a relief valve 111 the most in parallel in foam pump 11 simultaneously, guarantee the normal work of foam pump 11, end at this foam filling line 1 is provided with applicator, this applicator is arranged on (not shown) in cutter head；Between the first check valve 13 and the second check valve 19 on each foam filling line 1, all individually side connects high pressure water cleaning pipeline 2, this each high pressure water cleaning pipeline 2 is all provided with the control ball valve 21 for water route break-make, and the water inlet end of each high pressure water cleaning pipeline 2 is pooled together and turned on water source end by an external high-pressure hydraulic pump 22 and check valve 23.
A situation arises for foam in observing foam filling line 1 for described foam visor 16.
Described ball valve 18 is as the unloading port of every foam filling line 1, when the applicator of front end plugs, and the pressure in pipeline is excessive, at this time artificially can discharge pressure by this ball valve 18, it is to avoid foam visor 16 overload ruptures；Hydrops in foam pipe can be discharged by this ball valve 18 simultaneously.
As shown in Figure 2, one slave computer 3, usually programmable logic controller (PLC) (PLC single-chip microcomputer), it is connected with the control ball valve 21 in pressure transducer 17, foam pump 11 and each high pressure water cleaning pipeline 2 of each foam filling line 1, for receive pressure signal that each pressure transducer 17 fed back and control foam pump 11 and control ball valve 21 open/close operating；One host computer 4, usually band screen and the computer of keyboard, this host computer operating platform also includes acoustic-optic alarm, and this host computer 4 is connected with slave computer 3, can receive the force value that slave computer 3 is fed back, and slave computer 3 is sent control instruction.
Control ball valve in aforementioned mentioned foam filling line and high pressure water cleaning pipeline may select: pneumatic ball valve or Solenoid ball valve or hydraulic control ball valve etc. can receive external command and realize the ball valve of break-make.
The operation principle of the anti-block apparatus of a kind of cutter head foam spout being applicable to shield machine of this utility model:
nullSuch as Fig. 1、Shown in 3，When shield machine is when carrying out foam and injecting operation，Foam is through foam pump 11、Pressure gauge 12、First check valve 13、Effusion meter 14、Foam maker 15、Foam visor 16、Pressure transducer 17、Second check valve 19，Finally spray from the distal foam spout of foam filling line，Carry out the dregs in soil cabin improveing operation，Pressure value is transmitted slave computer 3 by pressure transducer 17 constantly in this process，And by slave computer 3, above-mentioned pressure information is transmitted on the host computer 4 of master control room，Pressure value P 1 in host computer 4 is by slave computer 3 real-time reception arbitrary foam filling line，When plugging fault operating pressure P2 appraised and decided in the foam filling line prestored in the pressure value P 1 ＞ slave computer in any of which foam filling line，The present embodiment P2=6BAR，Host computer carries out alarm，The foam filling line of this blocking need to be carried out by prompting staff，There will be following two operation to select:
nullSituation 1: if now staff finds the alarm that host computer 4 sends，Clear instruction is sent to slave computer 3 in time by host computer 4，Then slave computer 3 can send, to the foam pump 17 of 1 in all foam filling lines, the instruction that quits work，And the control ball valve 21 in the high pressure water cleaning pipeline 2 being connected with this road foam filling line 1 switches to opening，Water under high pressure in high pressure water cleaning pipeline 2 is introduced in this road foam filling line 1，The applicator of foam filling line 1 end is rinsed，The flushing persistent period is 10S，The control ball valve 21 in high pressure water cleaning pipeline 2 is closed after 10S，After the 5S of interval，When force value in this foam filling line 1 is stablized，Slave computer 3 detects the force value in this foam filling line 1 again，Until the force value again detected is less than the maximum P3 of the service pressure appraised and decided in the foam filling line 1 that prestores in slave computer 3，P3=5BAR，Then system recovery normally works，Foam pump starts，Foam filling line proceeds foam and injects operation；
nullSituation 2: if now staff is due to work carelessness，Clear instruction is sent to slave computer 3 the most in time by host computer 4，Force value in the foam filling line 1 of this road blocking can persistently raise，When emergency shutdown false pressure value P4 appraised and decided in the foam filling line that pressure value P 1 ＞ slave computer prestores，This embodiment P4=8BAR，Then slave computer 3 foam pump 1 in trend all foams filling line can send the instruction that quits work，And the control ball valve 21 in the high pressure water cleaning pipeline 2 being connected with this road foam filling line 1 switches to opening，Water under high pressure in high pressure water cleaning pipeline 2 is introduced in this road foam filling line 1，It is rinsed to the applicator of foam filling line end，The flushing persistent period is 10S，After the 5S of interval，When force value in this foam filling line 1 is stablized，Slave computer 3 detects the pressure value P 1 in this foam filling line 1 again，If P1 is ＜ 5BAR，Then system recovery normally works；If P1 >=5BAR, then slave computer 3 as aforementioned in situation 2 as described in flushing flow process, again the foam filling line of this blocking is carried out high pressure rinse, detecting, the flush cycle number of times that this slave computer is preset is 3 times again, after circulation flushing 3 times, if 5BAR≤P1 is ＜ 8BAR, then sending flushing by host computer 4 to slave computer 3 and control control instruction, until P1 ＜ 5BAR, system recovery normally works；If P1 is ＞ 8BAR, then slave computer 3 stops sending auto-flushing instruction, and host computer 4 sends the alarm needing manpower intervention to be purged blocking pipeline, personnel enter and carry out artificial dredge blockage pipeline inside shield machine.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
