According to the hard rock heading machine cutter feeding dust removing spraying system, spraying flow of each sprayer can be conveniently controlled, different working conditions are adapted, spraying effects are improved, and dust raising is reduced; and the working state of each sprayer can be conveniently detected, and plugging of each sprayer is prevented.
Description
Technical field
The utility model belongs to the hard rock mole cutterhead, is specifically related to a kind of dedusting spraying system of hard rock mole cutterhead.
Background technology
For increasing work efficiency and construction quality, reduce personal injury, the hard rock moles (TBM) that use in the mountain tunnel construction of present long distance more.TBM comprises shield body 1, is located at the cutterhead 7 of shield body 1 front end as shown in Figure 1, and the rear end of dish 7 is connected with swivel coupling 8.In the TBM work progress main by cutterhead 7 with tunnel the place ahead catalase, the huge dust of usually can kicking up in the rock dropping process makes that environment becomes more abominable in the relatively poor tunnel of ventilation condition.Just need reduce dust emission at cutterhead front spray for dust suppression this moment.Existing TBM dedusting spraying system comprises the some shower nozzles 2 that are located on the cutterhead 7, and all shower nozzles 2 are supplied water by a water pipe 9, and water pipe 9 is provided with pressure meter 3, safety valve 4, high-pressure hydraulic pump 5 and ball valve 6.This dedusting spraying system provides high-pressure water by high-pressure hydraulic pump from the water intaking of tunnel industry water, has only a pressure meter 3 to be used for monitoring pressure, directly enters cutterhead 7 by swivel coupling 8, carries out spray for dust suppression in cutterhead 7 inside with the pipeline demultiplexing.Its shortcoming one is the discharge skewness, can cause one or several shower nozzle water yield bigger than normal, and remaining water yield is less than normal or do not have the water ejection, and dust removing effects is undesirable; The 2nd, often occur shower nozzle 2 in the construction and stop up; the uncontrollable problem of the water yield; shower nozzle 2 stops up the back is inconvenient to check; need to shut down the back workman emitting spray water to the space very narrow and small and can occur at any time caving in, the face of rock burst carries out inspection and maintenance, the working strength height, there is threat in personal safety.Therefore improve the dedusting spraying system, it is significant to improve nebulization efficiency, reduction personnel labor intensity and danger coefficient.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can improve spray effect, reduces airborne dust, prevents the dedusting spraying system of the hard rock mole cutterhead that shower nozzle stops up.
Realize that the technical scheme that the utility model purpose adopts is: the dedusting spraying system of hard rock mole cutterhead comprises the some shower nozzles that are located on the shield body cutterhead, and each shower nozzle is supplied water by a water pipe separately.
Be equipped with pressure sensor, flow meter, pressure meter, safety valve, high-pressure hydraulic pump and ball valve on the described water pipe, wherein ball valve is connected with the water source, high-pressure hydraulic pump 5 is connected on after the ball valve, and safety valve is located on the pipeline that connects the high-pressure hydraulic pump import and export, and pressure meter is located at the exit of high-pressure hydraulic pump.
The water source is through ball valve, pressurize by high-pressure hydraulic pump, the water under high pressure delivery side of pump is installed safety valve, the safety of system when guaranteeing system overpressure, setting pressure table on the pressure piping of high-pressure hydraulic pump outlet can on-the-spot display system pressure, pressure sensor and flow meter be monitoring system pressure and flow at any time, give PLC with signal feedback, judge whether operate as normal of system, whether the phenomenon of stopping up shower nozzle is arranged.The technical scheme that its technical problem that solves the utility model adopts is: each the bar water route that is used to spray all is the single pump control of single channel, provide pressure water source by high-pressure hydraulic pump, dispose flow meter, pressure sensor on the water route in order to monitor mist flow and pressure at any time, by the feedback signal that flow meter and pressure sensor provide, PLC judges automatically whether shower nozzle stops up.
High-pressure hydraulic pump can be supplied high-pressure water, control the rotating speed of high-pressure hydraulic pump with variable frequency adjustment, according to the pressure flow characteristics auto of shower nozzle, utilized pressure sensor, flow meter is accurate measures and feedback, pressure and flow-control in optimum value, can be reached the spray effect of shower nozzle the best.Can also regulate suitable injection flow rate according to the airborne dust size at scene, alleviate the too much water yield and give the inconvenience of slagging tap and bringing, and can save the tunnel water.In work progress, in the duty that just can see each shower nozzle on the cutterhead on the control panel, check to face jeopardously without the staff, not only improved operating efficiency, and reduced threat staff's personal safety.
The utility model can be controlled the mist flow of each shower nozzle easily, adapts to different operating modes, improves spray effect, reduces airborne dust; Can easily detect the duty of each shower nozzle, prevent that shower nozzle from stopping up.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the dedusting spraying system schematic diagram of existing hard rock mole.
Fig. 2 is a dedusting spraying system schematic diagram of the present utility model.
Among the figure: 1, shield body, 2, shower nozzle, 3, pressure meter, 4, safety valve, 5 high-pressure hydraulic pumps, 6, ball valve, 7 cutterheads, 8 swivel couplings, 9, water pipe, 10, pressure sensor, 11, flow meter.
The specific embodiment
Referring to Fig. 2, hard rock mole comprises shield body 1, is located at the cutterhead 7 of shield body 1 front end as shown in Figure 1, and the rear end of dish 7 is connected with swivel coupling 8.The dedusting spraying system of hard rock mole cutterhead comprises the some shower nozzles 2 that are located on shield body 1 cutterhead 7, and each shower nozzle 2 is supplied water by a water pipe 9 separately; Be equipped with pressure sensor 10, flow meter 11, pressure meter 3, safety valve 4, high-pressure hydraulic pump 5 and ball valve 6 on the described water pipe 9, wherein ball valve 6 is connected with the water source, high-pressure hydraulic pump 5 is connected on after the ball valve 6, safety valve 4 is located on the pipeline that connects high-pressure hydraulic pump 5 import and exports, and pressure meter 3 is located at the exit of high-pressure hydraulic pump 5.
Dedusting spraying system of the present utility model is the single pump control of single channel, and 8 shower nozzles are arranged on the cutterhead, 8 high-pressure hydraulic pumps and other control elements of use, and whether the water yield that can reach each road can be controlled separately, can also monitor shower nozzle at any time and stop up.High-pressure hydraulic pump is all fetched water from the tunnel industrial water use, spraying provides high-pressure water to shower nozzle, and POF and pressure are monitored at any time by pressure sensor and flow meter, and feed back to the PLC control system, on the hard rock mole control panel, show the flow and the parameter on each road.Suitable pressure flow match parameter scope is set all according to the pressure flow characteristics auto of shower nozzle in each road.If flow that monitors and pressure depart from the scope that sets, for example: pressure raises, and flow reduces or do not have flow, illustrates that shower nozzle is blocked.Each bar pipeline is corresponding with the shower nozzle numbering on the cutterhead, and when showing which is blocked on the control panel, the staff can learn easily, gets final product thereby find the fault shower nozzle to repair when shutting down accurately.
