Description of drawings
Fig. 1 illustrates the exemplary embodiments of rock drill of the present invention.
Fig. 2 illustrates the block diagram of describing exemplary embodiments of the present invention.
The specific embodiment
Fig. 1 illustrates typical rock drill of the present invention.Rock drill 1 is shown in the drawings, is the ground drilling frame in this example.Shown in derrick 1 be used to hole 2, from ground, at present the hole arrives degree of depth α and will make and is directed at one and is the hole of β deeply, for example 30 meters, the hole of finishing dots.(relation of the derrick height/hole depth that illustrates is estimated inaccuracy.The overall height γ of rig for example can be 10 meters).
Derrick 1 is provided with top hammer 11, and this top is hammered 11 into shape and is installed on the feed mechanism 5 by rock borer frame 13.Feed mechanism 5 is connected on the support arm 15 by feeding retainer 12.Top hammer 11 provides percussion by the drilling rod 6 that is supported by bar support 14 to the drilling tool 3 with one or more drill bit 4.The power of top hammer 11 come free diesel engine 9 that drive, be connected to hydraulic pump 10 (hydraulic feed unit is not shown in the drawings) on the feed mechanism 5 by conduit.Utilize compressed air that drilling cuttings is developed from hole 2, this compressed air is supplied with by the pipe that is preferably placed at drilling rod 6 centers, and discharges near the drilling tool 3.Compressed air makes progress drilling cuttings through via hole 2 and from wherein developing, and is such shown in Fig. 1 arrow up.Compressed air instead, other scouring media also can use, and for example has or do not have the water smoke of chemical addition agent.Compressed air supplies to drilling rod 6 from compressor 8 by managing 7.Compressor 8 drives with diesel engine 9 again.
In current derrick, diesel engine 9 should be enough big, with can be simultaneously drive compression machine and hydraulic pump at full tilt, and drive cooling fan and other utensil.During holing, always with maximum rate or near its maximum rate drive compression machine, and because compressor can consume for example 120hp in the 300hp diesel engine general output for example, so a large amount of fuel of compressor consumption, this causes producing a large amount of waste gas, noise and heat, because cooling fan needs to drive more consumingly, therefore further cause bigger noise and more fuel consumption again.
But,,, can reduce these shortcomings by with current required power stage drive compression machine according to the present invention.For example, when jewel hole began, it was less relatively to produce the required flushing power of the flushing medium flow be enough to discharge drilling cuttings, so compressor does not need this required bigger power of delivery ratio.This means, also can drive diesel engine with the horsepower output that reduces, therefore cause fuel consumption to reduce, the heat of generation is less and noise that produce is also little.On the other hand, can be used for making more power can be assigned in the hammer of top by the power of saving like this with the input power drive compression machine that reduces, this is than more possible with other method, thereby causes in the first in hole and/or major part jewel hole speed faster.
According to the type of compressor, the power that can finish this compressor in a different manner reduces.For example under the situation of positive displacement compressor, by reducing R.P.M or giving the compressor unloading cpable of lowering power by closing inlet.
Describe the control of compressor horsepower referring now to Fig. 2, this Fig. 2 illustrates the block diagram of control system.This illustrates the derrick 21 with diesel engine 22.Diesel engine is connected to compressor 23, hydraulic pump 29, cooling fan 24, other utensil 25, top hammer 26 and controller 27 directly or indirectly, on computer.This controller is also connected on compressor 23 and/or hydraulic pump and/or cooling fan 24 (a plurality of) and/or the utensil 25.
In order to control compressor horsepower, for example being installed in sensor 28 on the feed mechanism provides the information of relevant current hole depth for controller 27, controller 27 for example is sent to the control signal that comprises the information relevant which power/pressure should be carried in the compressor 23 by the CAN bus then, so that produce required flushing medium flow.In case of necessity, controller can be further with control signal, and for example required performance number sends to diesel engine and/or cooling fan and/or other utensil.Controller 27 can comprise and being positioned at wherein or connected memory 30, stores in this memory because the compressor setting value to the required numerical value of hole depth, makes compressor can obtain correct adjustment.On the other hand or in addition, can also store the calculating parameter that uses with hole depth, to calculate required compressor horsepower.These calculating parameters can be relevant with the type of the type of drilling tool and/or drilling rod.Preferably, may make up the storage calculating parameter for each of drilling tool and/or drilling rod.In the embodiment that replaces, have the tabulation that is stored in the memory, wherein, each tabulation comprises the compressor setting value and the degree of depth of each combination.For example, can be each centimetre or decimeter or the hole depth numerical value storage of Mi Zengjia.Can also store the numerical value that flow is increased along with the hole depth increase, so that compensate above-mentioned factor.
(not shown) in another typical embodiment, the sensor that detects actual flow can be connected on the controller, so that controller can send to control signal in the compressor continuously according to flow value.This flow for example can be with the revolution that rises number * per minute (R.P.M) * of compressor revolution working time/calculate total time.
In the exemplary embodiments of replacing, in control, set a numerical value or by man-machine interface by operating personnel, such as display and/or keyboard desirable value is input in the controller and can sets required flow.
For example, the present invention has such advantage, and promptly when boring pore, therefore compressor needn't, reach the purpose of fuel saving and/or top hammer excess power with capacity operation in whole jewel hole process in the jewel hole process.
In the explanation, the present invention has been described relevant ground drilling frame with hydraulic pressure top hammer drill car in the above.But the present invention can use with any other type jewel hole equipment with the flushing of branch power and jewel hole comparably.For example, the present invention can use with the rock drill that utilizes impact and rotation to bore the rock operation.The present invention also can be used for only utilizing the brill rock operation of rotation and impressed pressure fractured rock, perhaps only uses and rotates the place of boring rock, and for example this may be to bore soft rock, such as the situation in colliery.If use the rotation fractured rock, then can utilize the power that reduces the flushing saving to be used to improve rotary speed, make jewel hole speed faster thus.
Will also be appreciated that many other sensors, for example temperature pick up can be connected on the controller, so that provide the useful information of control rock drill operation for it.
