1cm.Common midge head 20 has regulated the distance between ground when in use, or is adjusted and ground by distance-measuring equipment
Distance between face, but in actual condition, ponding is muddy water mixing in tunnel, and midge head 20 is apart from adjusting not in place will lead to
The problems such as suction is insufficient, and midge effect is poor；And elastic exterior cover is set here midge head 20 may be implemented and adjust simplicity, midge effect
It is effectively controlled；Specifically according to 17 inspection result of detection probe, midge head 20 and ground contact force are controlled by telescopic arm
Size；When muddy water depth, elastic exterior cover contacts ground, when muddy water is shallow, applies pressure to midge head 20, so that suction nozzle sheet
Body 21 becomes smaller with ground distance, and the setting of elastic exterior cover and suction nozzle ontology 21 can guarantee suction nozzle ontology 21 and ground most narrow spacing again
In a certain range from holding, the problem coordinated suction and prevented suction inlet too small.
Gas storage component can store 3 gas bleeding of vacuum pump in this programme, and energy is recycled；Tool
Body process is to make midge process by reversal valve 5, and gas in pulp absorbing box 6 is pumped into air accumulator 4 by vacuum pump 3, in plasma discharge
Air accumulator 4 is connected to by journey, reversal valve 5 with pulp absorbing box 6, and the gas in such air accumulator 4, which is discharged in pulp absorbing box 6, arranges pulp-water
Out.Whether midge component may be implemented to have pulp-water to detect in region locating for shield locomotive frame and guides midge head 20 is corresponding to draw,
Here entirely control and detection are completed by control assembly.
The selection of vacuum pump 3 XD-100 type of the present invention, vacuum degree >=0.095MPa, pumping rate 100L/min, power 11KW,
Revolving speed is 900-1000r/min, temperature rise≤60 DEG C.According to live actual test, circle which can be 35 meters with pair radius
Mud in all ranges is absorbed.In addition XD-100 type vacuum pump 3 is equipped with non-return valve in the air entry 61 of pump, when pump stops work
Non-return valve and the interior aeration aperture synergy being specially arranged of pump, can make pump with by pumping isolation of system immediately, prevent pump oil when making
It returns by pumping system, while also maintaining the vacuum degree in vacuum tank.
The selection of 6 installation site of pulp absorbing box: in conjunction with practice of construction scene, the place for most easily producing mud belongs to connecting bridge
Lower part and shield machine No. 5 towing carriage tail portions dregs mouth position, and the absorption region pumped is within 35 meters.Since shield locomotive frame is real
About 70 meters of border length, and the place that can store vaccum pulp absorbing case 6 and midge equipment only has No. 3 trailer tail portion leftward positions, belongs to
The whole central location of shield locomotive frame, in this way since, the absorption region of vacuum pump 3 is not only met, in plasma discharge without again
Mud can be directly discharged into native case by the position that dregs case is adjusted by starting 2 vehicle of motor, also be saved to a certain extent
About time.
The design of pulp absorbing box 6: being limited by installation site, and pulp absorbing box 6 cannot design too greatly, according to rear mating No. 3 trailers
Tail portion leftward position, pulp absorbing box 6 are designed as long 1800mm, wide 900mm, and high 1800mm can disposably store 2.5m3Mud
Slurry.However, maximum problem is to generate precipitating after mud is drawn into pulp absorbing box 6, certain difficulty is brought to plasma discharge, according to existing
Actual conditions, thick liquid discharge mouth can not be designed in vacuum pot bottom, bottom not only limited space, in addition operation and its inconvenient.Needle
To this problem, improvement is made that 6 configuration of pulp absorbing box first, the height of bottom up 339mm is designed as ramp type, is added
The flow velocity of mud when fast plasma discharge.In addition, devising the window of 560mm wide 300mm one long on the slope close to outside, and add
Adhesive tape sealing is sealed inside twice, and periphery is tightened up using the bolt of 18 M12X25-8.8.So that if hair
Raw precipitating mud can not outlet when, manual cleaning can be carried out by opening this window.Since the design meeting band of ramp type makes to inhale
Slurry case 6 places shakiness, therefore is fixed in the position at 6 four angles of pulp absorbing box welding foot prop.
For the setting of stock inlet 62 in 6 upper position of pulp absorbing box, outside installation 80mm ball valve controls the beginning and stopping of midge,
Pulp-absorbing pipe 7 selects the high pressure steel wire hose of 80mm, is laid with from vehicle frame top to connecting bridge position.Grout outlet 63 is arranged under side
Portion, the external start-stop that plasma discharge is equally controlled using 80mm ball valve.
Sucking mud: reversal valve 5 is adjusted to connect vacuum pump 3, presses 1 start button of switch control box, threephase asynchronous machine 2
Rotation drives vacuum pump 3 to work, and the air in pulp absorbing box 6 continuously passes through reversal valve 5, and storage is entered from vacuum pump 3
In gas tank 4.Air is reduced in pulp absorbing box 6, then will form negative pressure, so that the pipeline of connection 6 import of pulp absorbing box has stronger suction
Power constantly sucks the mud of shield motor spindle.Mud enters in pulp absorbing box 6, is affected by gravity, and falls to bottom, protects
Demonstrate,prove the unimpeded of gas circuit.After completing work, 6 inlet ball valve of pulp absorbing box is closed, presses 1 stop button of switch control box, closes electricity
Machine 2 is run.
Mud is discharged: opening 6 vent ball valve of pulp absorbing box, reversal valve 5 is adjusted to connect air accumulator 4.Have in air accumulator 4 very strong
Air pressure, air enters pulp absorbing box 6 by reversal valve 5, and pulp absorbing box 6 accelerates the row of internal mud since internal pressure increases
Out.When if there is the inadequate situation of air pressure, the start button of switch control box 1 is pressed, the rotation of motor 2 drives 3 work of vacuum pump
Make, from outside, sucking air enters air accumulator 4, increases by 4 air pressure inside of air accumulator, guarantees the normal work of system.
Operating process: it is mobile that control cabinet 1 controls sliding machine 9, and sets moving distance；After sliding machine 9 stops, control
Case 1 controls lifting device expansion, and detection probe 17 is unfolded in region, and the specifically electronic control of folding portion 16 detection is visited
17 drops down of needle, when the pressure sensor of detection probe 17 detects signal, control cabinet 1 receives the electrode of detection probe 17
Probe detection signal, judges whether there is slime water and its depth, and electronic folding portion 16 controls detection probe 17 and receives folded, air guide upwards
Pipe 23 cleans 17 jet of detection probe；It is repeated the above process in multiple regions；So that control cabinet 1 judges that mud deposits feelings
Condition.After mud deposition is controlled in judgement, case control midge head 20 processed is moved down, the work of midge system.It detects in this process
Probe 17 while cooperating, understand midge situation to facilitate.It certainly, is more preferable removal mud, it can also be in sliding machine 9
Sprinkler head is set, and sprinkler head connects water system, and water system connects control cabinet 1.
Above description is the detailed description for the present invention preferably possible embodiments, but embodiment is not limited to this hair
Bright patent claim, it is all the present invention suggested by technical spirit under completed same changes or modifications change, should all belong to
In the covered the scope of the patents of the present invention.
