Description

SOUND HEADS AND ASSEMBLIES AND USES OF THEMSELVES Field of the Invention The present invention relates to vibration or sound generation ("sound") as it may be useful, inter alia, in sonic drilling. The invention relates to related apparatuses, methods, systems and procedures.

Background of the Invention There is often a need to provide vibration. Examples of use of vibration include buoyant separation procedures of particulate materials among other particulate materials, sand devastation of a molded article, operation and drilling of soil or other compaction, of piles (including directional and / or rotary drilling). Usually release is generated depending on the rotation of an eccentric weight or counter-rotating weights. See, for example, U.S. Patent No. 3,866,480 which describes an orbital vibrator. These orbital mass vibrators can employ orbital rollers that are rotationally propelled around the inner race wall of a housing, as described in U.S. Patent No. 4815328 to Bodine, or an unbalanced rotor, the output of which is coupled to a drill bit as described in United States Patent No. 4261425 to Bodine. Other methods for creating and using sonic energy for application to a mandrel are also described in US Patent Specification Nos. 3375884 (Bodine), 3379263 (Bodine), 4836299 (Bodine), 4527637 (Bodine); 5549170 (Barrow) and 5562169 (Barro) and WO 01/83933 (Bar-Co en). Japanese Patent Specification 57-179407 by Kawasaki Heavy Ind. Ltd discloses a pile hammer that employs a fluid actuator to operate in accordance with the pile resonance for the inherent soil frequency by providing a relief valve and a surge circuit. derivation. The amplitudes of movement beyond those purely attributable to liquid volumes are indicated as obtainable. Other devices that use hydraulic fluids to create vibratory impact are shown in Australian Patent 479534 (A / S Moelven Brug) (see US 3747694). A preferred use of interest heretofore for the vibration apparatus, but not one to which the vibration apparatus needs to be restricted, is in the support of the well bottom drilling or drilling rig. Other uses include those discussed later in this. A variety of different prior art procedures have been described that include our own patent specifications dependent on the well-drilling directional drilling apparatus capable of being controlled through the drill string. The motive force is advanced and / or rotated above the ground or in an excavated soil region. However, in some applications, it is a preference to subject the drill string to the drill string at rapid vibrations, thus allowing movement through the soil by breaking up rock structures encountered in compacting the surrounding, thereby reducing the materials that are removed from the bottom of the well. These procedures, whether dependent on resonance within the drill string or not, are referred to as perforation in sonic drilling. Sonic drilling methods and apparatuses are described, inter alia, in U.S. Patent Nos. 4836299, 4548281 and 5417290 which are incorporated herein by reference. Sonic drilling is achieved by vibrating a drill string to produce compressive and expansive slings in the drill string. The vibrations are induced in a longitudinal direction of the drill string and the drill string is vibrated preferentially at a resonant frequency. The resonant frequency is dependent on several factors including the length of the drill string. The vibratory forces in the drill string cause the drill string to contract and expand in the longitudinal direction. The vibratory forces at the bottom of the short drill string, displaces and / or otherwise fractures the soil and / or rock articulations thereby cutting through the formation. Drilling systems employing cycloidal sonic energy have also been described in the art as a method for drilling to cause a highly effective action on the bottom and particularly on the adjacent side walls of the bottom portion of a well by virtue of the action Cycloidal drilling The present invention recognizes a derivable advantage in the area of sonic drilling where it is possible to start generating the sonic head while it is in its operative connection (directly or indirectly) with the drill string. For many sonic head shapes of the prior art re-starts are difficult due to the need to contract the drill string from against a cutting surface and other structure that may be attached to the drill string as a whole. Therefore, an object of one or some embodiments of the present invention is to provide a sonic head assembly and / or a sonic head for this assembly that will provide the starting option without the need for retraction in some circumstances and / or the separation of the sonic head in the drill string. It is an object of one or some aspects of the present invention to provide a sonic head assembly and / or sonic head for this assembly that allows the generation of vibrations including sonic vibrations in a structure without a requirement to adjust to a resonant frequency of the structure to make it vibrate. In some aspects of the present invention it is contemplated that the start can begin without the need for resonance to be achieved but in some embodiments of the present invention this resonance can still be achieved by adjusting the control parameters as the instrument is being used. sonic head assembly. In one or more other embodiments of the present invention, it is an object to provide a sonic head and / or a sonic head assembly not dependent on eccentric rotation but imparting a useful sonic output that can be used in many situations or that provides at least to the public with a useful choice. It is an object of one or some other embodiments of the present invention to provide constructions of a fluid driven drilling chain for a sonic head assembly that confers some measure of isolation of the key components of the affectation by excessive vibration and / or by the omission of the component or components that avoids the difficulty of these vibrations. It is an object of one or more embodiments of the present invention to provide a related sonic head dependent on separate feeds of fluid, one for imparting vibration and at least one for controlling, other input parameters, eg, amplitude, frequency, valving , etc. It is an object of one or more other embodiments of the present invention to provide a sonic head and / or sonic head assembly having a fluid recovery and delivery system that takes fluid at ambient pressure or near ambient pressure (preferentially before returning to the sonic head). It is an object of one or more other embodiments of the present invention to provide arrangements and / or shock absorbers. and / or sonic head support couplings that provide some freedom of movement between at least part of the sonic head and a support frame that still allows some relativity of movement therebetween. The invention also relates to a vibratory apparatus and to the related methods of operation and use that will provide at least one useful choice.

Optional rotation of the mandrel 47 will rotate or hand a drill string attached thereto while the mandrel or equivalent 47 can be vibrated (directly or indirectly) under the action of the proximal piston or the complementary means of the sonic head. This proximal piston, piston assembly or complementary means is preferably supported so that some degree relative to the frame 45 can be moved at least in a longitudinal direction and some guided couplings are preferably provided for this purpose. For example, the links 50 and 51 on either side of the sonic head can be linked by a pivot 52 or 53 to the sonic head and by 54 and 55 to the frame 45. At the same time, movement limits can be imposed by the springs 56 and 57 compression (or airbags) in preferential connection with the airbags 58 and 59 that provide a cushioning or damping effect between the sonic head and the frame 45 and in turn the carriages or supports 44 and 46. Therefore, it can be seen that the couplings allow some semblance of rotation of dog bone joints as long as a? at the same time allow some axial displacement of the sonic head as a whole, yet the shuttle 36 is free from direct contact with the frame and / or the slides or carriages 44 or 46 otherwise as a consequence of the flexible drive units and the hose and / or other couplings not shown in the accompanying figures. Preferably, all connections (including hydraulic) are flexible hoses resistant to vibration connected to prevent inadvertent disconnection. The sonic head of the present invention can be started by a hammer effect even without the drill string set for resonance. Subsequently, the control may be (a) speed of rotation valves (rotor) and / or fluid volume (e.g., oil). This can alter the frequency but allows the power to be added independent of the length of the drill string. The drill string can have the torque and pressure placed on it without affecting the sonar head resonator or shuttle with back and forth movement. This offers huge drilling control. Independent systems for rotor control of that of a shuttle oil supply, the vibratory isolation of the sonic head, mainly the sonic shock, the frame within a framework arrangement, and the short distance of the oil shock trip give advantages significant The operation of the cycles as in Figures 7 to 9A will now be described with the apparatus having the flow capabilities described above. It is appreciated where a device as shown in Figures 1 to 9A ie 1.5 m long, the back and forth movement is of the order of say 0.1 mm to 15 mm (the amplitude), the operating parameters that affect The amplitude. The operation can be a direct movement with a millisecond interval as in the scenario (A) referred to with respect to Figure 7 (ie, Figure 8 ', Figure 9', etc.) but it can be the scenario instead (B) ) where conditions like. in Figures 8A and 9A each require an accumulator in the oil circuit to allow the required momentary movement to the next instantaneous condition of Figure 9 and Figure 8, specifically. It is contemplated that the apparatus according to the forms of the present invention as shown in Figures 10 to 13 will be preferentially driven by a hydraulic system of eg, an excavator (or other vehicle or a right mobile apparatus) and therefore the various sources of pressurized liquid and reservoirs referred to herein are preferably those of a supply excavator, etc., to which the apparatus. Also, preferentially there may be a deviation in the inlet flow to the apparatus of this pressurized hydraulic fluid through shut-off and / or shut-off valves, etc., as may be required separately to provide a hydraulic drive to a of the rotary valves (and thus by synchronization joints in turn to the other) as well as separately the fluid load immediately to each chamber end region. In the region shown in Figure 10, the piston 60 has hinged extensions 61 to allow axial movement. It does not matter whether the piston and the joints are circular in cross section and / or whether they are allowed or not to rotate within the chamber defined by the camera assembly 62. As can be seen in the embodiment of Figure 10, there is a first chamber end region 63 and a second chamber end region 64 each being followed by an inlet orifice 65 and 66, respectively. Positioned to rotate substantially about an axis normal to the stroke axis the piston 60 is in the rotary valve 66 having in the same radius area no opening 67 and opening 68. As can be seen one of these openings 68 (designated 68A) is opening the pressurized liquid supply chamber 69 of the fluid supply in communication with the chamber end region 63 while there is no access via the second inlet port 66 in the region 64 of the chamber end due to the out-of-phase condition. phase, that is; to a region 67 that retains the second inlet hole 66 closed while opening the first inlet 65. The situation from vice versa to the front will allow the alternating load to each region of camera end. As shown in Figure 10, there is a first exhaust or exit hole 70 for the chamber end region 63 of a second outlet orifice 71 for the chamber end region 64. In a situation as shown in Figure 10, where these holes are always kept open, preferably a means (in this case, a plate having openings 72 and 73) different from a second rotary valve ensures that the flow of Liquid entry via an opening 68 and an orifice 65 or 66 will always be at a higher speed than that of any exhaust outlet via the corresponding outlet 72 or 73 as part of a hydraulic return circuit. Those skilled in the art will appreciate how the fluid supply assembly 74 can be supplied with an inlet supply of a hydraulic fluid in the chamber 69 with the fluid finding its own path therein in one or other of the regions 63 and 64 of the chamber end and from there via the outlet orifices (70 and 72 in one case and 71 and 73) in the other case back to the pumping end for example of the excavation with which the apparatus for the return of that same hydraulic fluid back to chamber 69 or a deviation therefrom, as may be considered desirable, to a hydraulic rotor for driving the rotatable valve 66. A more preferred form of the present invention is that shown in Figure 12. This has similar to Figure 10 a piston 75 and articulated extensions 76 and 77 thus defining chamber end regions 78 and 79 controle by, for example. , the valve 80 rotatable with its openings and not openings arranged in a manner similar to the manner shown by reference in the embodiment of Figure 10. The assembly 81 with its chamber 82 is adapted to receive pressurized hydraulic fluid and to selectively allow its movement in the first and then the other of the camera end regions 79 and 79. Synchronized to the rotation of the valve, 80 rotatable is a rotary valve member 83 having role to allow the escape of hydraulic fluid from the first and then the other of the chambers 78 and 79 in an out-of-phase relationship to that of the injection for the reciprocating movement of the piston in this way. The rotatable exhaust valve 83 preferably rotates at the same speed as the rotary valve 80 and the spacings of its openings are appropriate for each outlet of the chambers 78 and 79. Figure 11 shows better the arrangement of these openings with an orifice 84 which closes as it is not aligned with an opening 85 of the inlet rotary valve 80 as an outlet orifice 85 of that end region 86 of chamber is aligned with an opening 87 to allow the outflow to the chamber 88 of the assembly 79 of fluid reflection from where you drive back via, for example, the excavator, for recycled, pumped use. The arrangement of Figure 13 shows a bank test of an electric motor 90 (ideally it will be a hydraulic motor in use) that directly drives a drive assembly adapted to rotate a first rotary valve (not shown) as a band 91. link through a free shaft 92 in turn through a second link band 93 actuate the other rotary valve (not shown) thereby providing the appropriate vibratory movement (caused by reciprocating movement of the piston) extending in the articulated output member 94. Therefore, in the operation, the appropriate adjustment of the required releases can be presented. Assuming that an excavator has the ability to provide a substantially constant hydraulic flow and pressure in the apparatus of the present invention and there is a division of the flow so that a flow can supply a hydraulic motor to achieve rotary valve rotation as long as "the other flow is to selectively load either side of the piston under the action of the rotating valve timing movement, apply a very simple control regime.This is quite less complicated with quite a few moving parts and requiring less tolerances than for any of The prior art methods described above, for example, if the inlet of a closing end by its rotary valve then the hydraulic fluid can not go anywhere and nothing will happen by means of the load in that end region or terminal region, however, on the contrary, the same will not be the case if that is partly or completely open. Accordingly, a rotary inlet valve is adjusted (rotated) the hydraulic oil flows to the piston chamber end region and forces the piston to the end of its stroke). The rotary valve remains open and through its synchronization or synchronism with another rotary valve, the "spent" hydraulic fluid is allowed to escape. At the same time subsequently (or both), the first rotary valve biases the oil to the other end of the piston and in turn forces the piston back. The hydraulic drive through synchronization bands means that if the rotary valves rotate in unison slowly (say 10 rpm), the piston will move back and forth very slowly but if both rotary valves are rotated by say at 1000 rpm, the piston can be moved, say, approximately 200 times per second. In this way, adjustment for various soil conditions can be achieved by the simple convenience of manipulating the speed of the rotating valves synchronized by the control of the fluid inlet to the hydraulic motor.
