Description
Technical field
What the present invention relates to is with driven by power drilling bit, to carry out the device of ground deep layer drilling well, belongs to industrial technology field.
Background technology
the trepan device that we see is fixed drill bit trepan mostly, be that drill bit is fixedly connected with bull stick, then by Mechanical Driven drilling rod, rotated, bull stick drives again drill bit to rotate, the rotating speed of bull stick is the same with the rotating speed of drill bit, on the ground drive unit has makes driven fuel dynamic engine, the electric-powered machine of also use having.In mechanical type trepan, the rotational kinetic energy of drill bit is transmitted by bull stick, when trepan carries out shallow-layer operation, drill bit and bull stick can also synchronously rotate normal, but when trepan gets into deep layer, it is very painstaking that drilling rod just seems, while getting into more deep layer, some bull sticks prop up to be unable to hold out to have produced and snap, and drilling engineering suffers a loss thus.For the driving force of bull stick strengthens, people take the way of overstriking bull stick, but the bull stick weight and volume of overstriking all strengthened, and the required kinetic energy of drilling well also will strengthen, and a large amount of deep layer drilling well bull stick transportation of sample, install and have all increased difficulty.
Summary of the invention
in order to reach better drilling well effect, also in order to reduce the weight and volume of drilling well drilling bar, machine is visited in a kind of mohole of my invention, and this mohole is visited kinetic energy that the drill bit of machine rotates not by bull stick transmission, but drives the moving drilling well of bit drills by conductor wire conduct power.Such trepan bit speed is fast a lot, and drilling depth is darker than common mechanical formula transmission drilling well machine drill also.
a kind of mohole spy machine taked technical scheme of dealing with problems is: owner is visited in mohole will be by drill bit, electro-motor, connecting rod, ground support, pressure apparatus, generator forms, drill bit is directly driven by electro-motor, electro-motor is fixed on an of connecting rod, the other end of connecting rod can connect more connecting rod continuously, there is conductor wire the centre of connecting rod, on ground support, there is pressure apparatus, connecting rod can slide and be moved down and press electro-motor and drill bit carries out drilling well by pressure apparatus compressing in sleeve, electric power is delivered to the electro-motor in shaft bottom by the conductor wire in the middle of connecting rod.
in mohole spy machine, needed energy is an electric power, and electric power can obtain from supply line, or trepan house generator.The electric energy of generator output is transported to electro-motor by conductor wire, and electro-motor rotates.Conductor wire be from connecting rod to downward-extension, conductor wire can be arranged on hollow the passing in centre of connecting rod, also can be arranged in the outer surface groove of connecting rod.Or every connecting rod is all fixed with the conductor wire with connecting rod equal length, there is plug and the jack of conductor wire at two of connecting rod, and when drilling well is deepened downwards, every lengthening connects a connecting rod, by plug and jack, can lengthen conductor wire simultaneously.
the electro-motor that machine is visited in mohole should have different power type, to adapt to the drilling well difficulty of Different Strata.Compared with the drilling engineering of hard formation, just select powerful drilling well electro-motor, general drilling well electro-motor is just selected in the drilling well on soft crisp stratum.Being fixedly connected with of dismounting property can be done with connecting rod in one end of electro-motor, and one end that the rotating shaft of electro-motor is stretched out is connected with drilling bit, and electro-motor can drive drilling bit to rotate drilling well.Drilling bit also have can be applicable to being arranged on electro-motor rotating shaft variety classes, have screw type bit, also have quincunx drill bit etc.The electro-motor of rig is placed in well, be subject to the restriction of the confined space in well, its peak power is subject to the impact of volume, although we lengthen electro-motor, but the peak power of electro-motor or less than the peak power of ground machine, because the volume of ground machine can ad infinitum increase.But although ground machine power is large, ground machine is owing to providing drilling well required whole kinetic energy on ground, this whole kinetic energy comprises that drilling bit bores the required kinetic energy in stratum and adds that all connecting rods rotate required kinetic energy; And mohole while visiting shaft drilling connecting rod and electro-motor health needn't rotate, therefore whole kinetic energy that electro-motor sends only need offer drilling bit and bore stratum, visible, the peak power of sending during electro-motor drilling well can be widely lower than the peak power of ground machine, therefore, electro-motor can be realized and in well, drive drill bit to carry out deep layer drilling well.
the ground surface support that machine is visited in mohole plays fixing, to support connecting rod vertically downward effect.On the ground surface support of trepan, be also supported with pressure apparatus, pressure apparatus can produce lasting pressure to the connecting rod that creeps into vertically downward, and drilling bit could little by little rotate to downward-extension like this.Although connecting rod needn't rotate in mohole spy machine, opposite force when but connecting rod is still subject to drilling bit rotation, this opposite force is the frictional force on drill bit and stratum, the immense strength that this frictional force will be carried whole kinetic energy generations with respect to connecting rod in mechanical type drilling well is much smaller, does not form the threat fractureing.
the machine beneficial effect of the invention is visited in a kind of mohole: a kind of mohole spy machine is placed in down-hole electro-motor and directly drives drilling bit to bore stratum, connecting rod needn't rotate, like this, boring the required kinetic energy in stratum only need just can be reached by conductor wire transmitting electric power, overcome by connecting rod and transmitted all kinetic energy loss that kinetic energy produces, also overcome connecting rod and transmitted the danger that kinetic energy generation fractures, drilling engineering is more carried out to deep layer.
