Description
Technical field
The present invention relates to a kind of underground no-dig technique heading equipment control system and control method.
Background technology
The compound shield that sea Rake company of Germany produces is one of shield machine the most advanced, and in site operation, this shield machine demonstrates that driving speed is fast, and efficiency of construction is high, the features such as construction quality is good.It is widely used in the construction of countries in the world city underground.
Sea Rake shield machine cooling system is divided into interior circulation and outer circulation two large divisions, wherein outer circulation part is by user's self design, require that user provides hydraulic pressure 16 bar, flow per hour 90 cubes outer circulation cooling water, requiring within 24 hours, uninterruptedly supply water, higher to job site water supply requirement, job site once water supply flow, pressure can not meet requirement, to directly contribute shield machine out of service, stop work in building site.Meanwhile, the cooling water of continual supply above-mentioned requirements, a large amount of outer circulation hot water can not reuse, and directly contributes the waste at water source.
Summary of the invention
The present invention is to provide for the control method of a kind of shield machine hydrologic cycle cooling system, the method combines job site practical situation, check through practice operation, on the premise of meeting shield machine cooling system requirement, a large amount of building site water of saving, minimizing water pollutes, and overcomes again building site for water unstable simultaneously, the external factor such as discharge is little, lay a good foundation for smooth engineering construction.
For achieving the above object, the technical scheme is that the control method of a kind of shield machine hydrologic cycle cooling system, comprise the concrete steps that:
(1) spare bits narrow and small in utilizing shield machine installs water-cooling circulating system；
(2) before man machine interface or local switch board send the instruction of ON cycle pump, first have to open the circulating valve in water-cooling circulating system or drain valve；
(3) during normal use, opening the High-pressure air valve in water-cooling circulating system, compressed air sprays atomization gas, rapid cooling water temperature at water tank bottom by atomizer；
(4) the most in use, automatic or manual pattern starts air cooling system, utilize air atomizer spray nozzle to spray atomization gas in cooling water tank, the recirculated water in cooling water tank is directly cooled down, when cooling water temperature is higher than setting value, atomization gas can not in time coolant water temperature time, closing circulating valve, open drain valve, current enter discharge casing, open water intaking valve simultaneously, supplement fresh cooling water.
During automatic mode, when cooling water tank water level is less than setting value, automatically opens up feed water valve, add fresh cooling water and be automatically stopped to designated water level, in reaching the short time with this, reduce the purpose of cooler-water temperature.
When discharge casing water level is higher than setting value, automatically turn on draining pump, discharge hot waste water.
The invention has the beneficial effects as follows:
The spare bits that the present invention is narrow and small in utilizing shield machine installs water-cooling circulating system, reaches the purpose to cooling uninterrupted in Suporting structure running；Utilize air atomizer spray nozzle cooling principle, in real time recirculated water is cooled down.Alleviate the contradiction that cooling water is rapidly heated, reach water-saving purpose；Realize under the project short time cuts off the water situation, shield machine being cooled down in real time, it is ensured that Suporting structure is properly functioning.Ensure the seriality of shield-tunneling construction.
Accompanying drawing explanation
Fig. 1 is the manual operation flow chart of the present invention；
Fig. 2 is to be automatically brought into operation flow chart.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Shield machine hydrologic cycle cooling system is mainly made up of water tank, pump, pipeline, flow transducer, pressure transducer, temperature sensor, level sensor, gases at high pressure, valve, atomizer etc..
Using Siemens S7-200PLC composition PPI network, implement remotely to control in conjunction with HMI man machine interface, whole control system and control method control stable, message transmission rate is fast, automaticity is high, has acted on the theory of a key control, has reduced the operation easier of shield machine operator.
As it is shown in figure 1, be the manual operation flow chart of the present invention.In a manual mode, sending command adapted thereto in man machine interface or local switch board, respective execution mechanisms works, it is adaptable to equipment debugging or adjustment operation.
The spare bits that the present invention is narrow and small in utilizing shield machine installs water-cooling circulating system；
Before ON cycle pump, first having to pressure opening circulating valve or drain valve, system is provided with protection, prevents stifled pump phenomenon.
The present invention utilizes two centrifugal pump of horizontal axis, two water tank enforcement water circulation through two, upper left side heat exchanger, and chilled water circuit is green pipeline；Hot-water return is faint yellow pipeline.When cool down current by the road time, pipeline color becomes highlight color, and at corresponding water pump display flow and force value cooling water tank display cooling water temperature and cistern water level.
During normal use, can open High-pressure air valve, compressed air sprays atomization gas, rapid cooling water temperature at water tank bottom by atomizer.The most in use, air cooling system can be started with automatic or manual pattern, utilize air atomizer spray nozzle to spray atomization gas in cooling water tank, the recirculated water in cooling water tank is directly cooled down.
When cooling water temperature is higher than setting value, atomization gas can not in time coolant water temperature time, close circulating valve, open drain valve, current enter discharge casing, can open water intaking valve simultaneously, supplementary fresh cooling water.During automatic mode, when cooling water tank water level is less than setting value, automatically opens up feed water valve, add fresh cooling water and be automatically stopped to designated water level, in reaching the short time with this, reduce the purpose of cooler-water temperature.
When discharge casing water level is higher than setting value, automatically turn on draining pump, discharge hot waste water.
Operating for equipment, pump or the icon of valve in pressing HMI interface can eject " startup " " stopping " " opening " the Close button.
Fig. 2 is the control flow under automatic mode.Automatic mode can only operate under remote mode.
When opening " automatic mode ", system ejects hint image, prompting operator's points for attention and ACK button, presses " cancellation " key, exits automatic mode；After pressing the delay of " confirmation " key 10 seconds, system is started working according to set point automatically, it is not necessary to manually intervene.
Parameter needs to preset in automatic mode.Simultaneity factor sets input range limit, over range will not input unreasonable or wrong parameter.
