Description
Technical field
The present invention relates to a kind of device that is used for tunneling the hole in the soil, comprise the main shaft that a rotation drives, this main shaft has an axle journal, and the axis of its axis and main shaft forms an acute angle; Also comprise a drilling head, it supports revolvably and has a circumference area around the axis of axle journal, and described circumference area is rolled on a corresponding circumference area.
Background technology
By the known this device of DE 4332113A1.
The lateral aperture that is about 150mm to 1300mm for aperture particularly, but also comprise the upright opening in the soil, adopt such drill unit, the axle that a rotatably mounted rotation drives in casing in this device is provided with drilling head at it on the end at the bottom of drift face or the hole.
Situation drilling head according to the soil that should inside hole is done to such an extent that have nothing in common with each other.Therefore changing appears in the situation when soil to be excised on boring length, just often encounters difficulties.Usually be equipped with the rock drilling head of roller, cutter head or cutterhead soft, for example can be stuck in the argillaceous soil, if run into rock or ratchel then because the high very fast inefficacy of wearing and tearing just in clay or loose sand, show the drilling head of good drilling performance.
This problem can solve by such method in by the device known to DE 4332113 A1, promptly, make drilling head produce an oscillating motion, therefore make it with high frequency with high kinetic energy drift face or hole bottom application are added fast and impact, but clear up the drilling cuttings that downcuts with big moment of torsion and slow rotating speed simultaneously, if perhaps the soil on the drift face is too soft, incrustly get off, just use big moment of torsion scraping soil so.Particularly can significantly improve drilling when the harder stratum by shock effect and import (rate of penetration).
In order to produce oscillating motion, the top rotatably mounted drilling head of the drive shaft of device towards the axle journal of drift face with respect to main-shaft axis installation in an acute angle.If main axis rotation drives now, drilling head is to be equivalent to the warble of the speed of mainshaft so, and the amplitude of oscillating motion depends on the distance of oscillation center and the size of angle of oscillation.
Self rotate slowly in order to produce drilling head, it is equipped with an outer bevel gear, and it rolls on the internal bevel gear of a fixed-site when doing oscillating motion.Drilling head is produced and the reciprocal rotating speed of main shaft, and have and depend on the speed ratio of outer bevel gear with respect to the structural parameters of internal bevel gear.Should reach 30: 1 to 60: 1 speed ratio.
Though actual showing is suitable for excavating very different soils by the device known to the DE 4332113A1, shortcoming is that the rotating speed of drilling head is not best for many ground conditionss, because too high mostly.
Shortcoming is in addition, is subjected to the drilling head of noticeable wear because its manufacturing of outer bevel gear is very complicated by drilling process, has improved the continuous running cost of this device thus.
Shortcoming is in addition, and intermeshing bevel gear is owing to entering of overburden caused bigger wearing and tearing.
Last shortcoming is that particularly big slug can not be discharged reliably, causes the obstruction of conveyance conduit easily.
Summary of the invention
Therefore the objective of the invention is, improve in this wise, make it be applicable in a big way different soils by the device known to the DE 4332113A1.
For this reason, the invention provides a kind of device that is used for tunneling the hole in the soil, comprise the main shaft that a rotation drives, this main shaft has an axle journal, and the axis of its axis and main shaft forms an acute angle; Also comprise a drilling head, it supports revolvably and has a circumference area around the axis of axle journal, and described circumference area is rolled on a corresponding circumference area, it is characterized by: corresponding circumference area can be rotated.
In device of the present invention, the rotation of drilling head drives and continues to be undertaken by such method, that is, it has a circumference area, and it rolls on a corresponding circumference area when main axis rotation.Now the drilling head that causes by rolling be rotated in its rotating speed aspect according to the present invention by such method control, can so that corresponding circumference area itself rotate.Therefore, according to the difference of corresponding circumference area direction of rotation, when remaining unchanged, the speed of mainshaft cause drilling head to close the rising or the reduction of rotating speed.
Corresponding circumference area and the circumference area of rolling on it can guarantee that the mode of during movement rolling is thrown off with any.But for convenience and the operational reliability made, circumference area preferably includes an external tooth, and corresponding circumference area comprises an internal tooth.
Corresponding circumference area be preferably made one with the internal gear of the concentric setting of main-shaft axis, according to the present invention its is rotated.
For by the device known to the DE 4332113A1, show in a period of time that in the past for many application scenarios, the ratio of the hunting frequency of drilling head and rotating speed is not best.For rate of penetration, the rotating speed that drilling head is lower is favourable mostly.Therefore a kind of preferred implementing form of apparatus of the present invention is imagined, and corresponding circumference area can produce rotation with main shaft planet gear meshed device by means of one.This form of implementation has such advantage,, compares the drive motors that it does not need other costliness with the device of same kind that is.The characteristics of this form of implementation are that it has extra high operational reliability in addition.
But corresponding circumference area also can be independent of main shaft by means of an independent drive unit produces rotation, that is corresponding circumference area is not connected with main shaft.The drive device is designed to controlled or adjustable then preferred especially, makes the ratio of run duration drilling head rotating speed and hunting frequency thus and treats that the type in drilling soil is complementary.
For fear of the rotating driving device overload of main shaft particularly with reduce the particularly wearing and tearing of drilling head, preferably establish such device, can be with it according to the power control or the adjusting amount of feeding of main axis rotation drive unit.Can impel by this structure, have best ratio between the driving power of the amount of feeding and drilling head all the time.
Drive if carry out the rotation of feeding and main shaft by means of hydraulic mechanism, such device so preferably is set, it is relatively controlled mutually or regulates the hydraulic pressure that causes feeding and main axis rotation to drive.If it is not high enough for example to be used to rotate the pressure of motor of driving, so just reduce the hydraulic pressure that causes feeding, till the operating pressure that is used for producing the CD-ROM drive motor that rotation drives is enough, if the pressure of CD-ROM drive motor is too high, so just reduce the hydraulic pressure that produces feeding, until till the pressure that same foundation is wished on the rotation motor.Consequently, guarantee that by this structure the best of device makes full use of, at this moment reach big as far as possible rate of penetration, and needn't often carry out manual adjustment for this reason.
In a kind of particularly preferred form of implementation of apparatus of the present invention, drilling head is made multi-piece type in this wise, make since with wait to excise the cutter that the soil friction is subjected to high wearing and tearing and partly can separate with supporting part.Make with drilling head by this measure and during its rotation, to carry out the situation that the relevant operating cost of the device of oscillating motion is not higher than the device of common work, because under the situation of drilling head wearing and tearing, bevel gear that the fabricating cost of drilling head is high and supporting member needn't be changed.If as preferred, drilling head is divided into a central support part and a cutter part that is fixed on above it, the replacing of cutter part so and is compared the situation about changing of whole drilling head for common unit, and the repacking time that is brought shortens greatly.Owing to the time efficiency that is realized thus and therefore the raising of unit interval rate of penetration operating cost is reduced on the contrary.
The cutter part is preferred especially by the drilling head structure of screw on supporting part.Screw is preferably uniform to be arranged on the reference circle of supporting part.
In a kind of improvement design of apparatus of the present invention, a sealing device that makes the supporting arrangement sealing of drilling head at least basically is set, prevent thus: the drilling cuttings that increases wearing and tearing enters the zone that circumference area is rolled on corresponding circumference area.
In a kind of preferred implementing form of apparatus of the present invention, sealing device comprises an elastic bellows.But it is used for compensating drilling head supporting part and non-oscillatory with the radially relative motion between the flange of excavation dish rotating speed rotation.This flange is preferably by the housing seal of a slide ring seal with respect to device.
Preferably, drilling head and carrier pipe receiving terminal are designed to like this, that is, the oscillating motion by drilling head will be positioned at those drilling cuttings of receiving terminal front and send into carrier pipe with mechanical system, make in the delivery ratio prior art of drilling cuttings much effectively to carry out.
If as preferred, drilling head its dorsad a side of drift face have at least one projection, it is similar to the receiving terminal that enters carrier pipe at least by oscillating motion, drilling cuttings just enters in the carrier pipe especially effectively so, and continues to carry in supply unit by the mechanical pressure in cycle.
Although, may cause the retardance even the pause of course of conveying, be preferably in and be arranged to the device that the big slug of major general is pulverized in the zone that is connected on the carrier pipe receiving terminal for fear of carrying effectively.
This device can be by active work, that is self-driven stone breaking machine is formed.But reducing mechanism comprises that the form of implementation of the broken muscle that extends is effective surprisingly considerablely and is convenient to make therefore preferred consideration in the carrier pipe cross section.
If receiving terminal is made the part annular in cross section, the validity of carrier pipe so, that is further improve with the unloading rate that it reached.That is to say that receiving terminal just can be symmetrical in its position, deep along the inner periphery in hole and be arranged in the hole, make and to go to overcome difference in height for " charging " of receiving terminal.
Be used for and will carry air to be blown into the attachment device in drilling head space if device comprises, as be used for by pneumatic discharger known in the art, unloading rate so can also improve.
