Description

Sonic Heads, Assemblies and Uses thereof {SONIC HEADS AND ASSEMBLIES AND USES THEREOF}

The invention relates in particular to the generation of vibrations or sounds (“sounds”) useful for sonic drilling. The present invention relates to apparatus, methods, systems and processes associated therewith.

Often there is a need to provide vibration.

Examples of the use of vibration include the removal of sand from the casting product, foundation or other compaction, among other particulate materials, and the buoyancy of particulate materials in pile driving and drilling (including directional and / or rotary drilling). Include separation processes.

In general, vibrations are generated based on spinning with eccentric loads or counter rotating weights. For example, US Pat. No. 3,866,480 discloses an orbital vibrator. Such orbiting mass oscillators are orbital rollers that are driven around the inner ring wall of the housing disclosed in Bodine, US Patent 4,815,328, or drill blades disclosed in Bodin, US Patent 4,261,425. Combined unbalanced rotors are employed.

Other methods of generating and using sonic energy by applying mandrel are also described in U.S. Pat. It is disclosed in the specifications of WO 01/83933 (Bar-Cohen).

Japanese patent 57-179407 of Kawasaki Heavy Industries discloses a pile hammer employing a fluid actuator that operates in accordance with the resonance of the pile at the natural frequency of the soil by providing a relief valve and a bypass circuit. . It is described here that motion amplitudes beyond those purely attributed to fluid volume can be obtained.

Another device using hydraulic fluids to generate vibration shocks is shown in Australian patent 479534 (A / S Melbourne Block) (disclosed in US Pat. No. 3,747,694).

Except for those who need to be limited to vibrators, the preferred use useful for us in connection with vibrators is the support of down hole drilling or boring equipment. Other uses include those discussed below.

Various other prior arts have been published, including their own patent specifications based on a hole-directed drill device that can be controlled via a drill string. It is advanced and / or rotated from a prime mover on the ground or in the excavation area of the ground.

However, in some applications, it is preferred that the drill string and drillhead follow rapid vibrations, thereby allowing movement through the ground by breaking up and impacting the surrounding rock structures and thus removing them from the ground. Reduce substances. Such processes, whether by resonance in the drill string or not, are referred to as sonic drilling or boring.

Sonic drilling methods and apparatus are disclosed in particular in US Pat. Nos. 4,836,299, 4,548,281 and 5,417,290, which are disclosed herein by reference.

Sonic drilling is accomplished by vibrating the drill string to produce a compressive and expanding wavelength in the drill string. This vibration is induced in the longitudinal direction of the drill string and the drill string is preferably oscillated at the resonant frequency. This resonant frequency depends on many factors including the length of the drill string.

The vibrating force of the drill string causes the drill string to contract and expand in the longitudinal direction. The vibrating force at the bottom of this drill string shears or removes soil and / or rock particles and / or breaks them on the other hand, thereby cutting tissue.

In addition, drilling systems employing cycloidal sonic energy as the drilling method work very effectively on the bottom and adjacent sidewalls of the bottom of the perforated well, in particular because of the drilling operation.

The invention has the advantage that it can be derived from the sonic drilling area which can start oscillation of the sonic head while in the operative connection (directly or indirectly) with the drill string. In many conventional sonic heads, restarting is difficult because of the need to pull the drill string from the opposite side of the rock surface and other structures that are all tied together in the drill string.

It is therefore an object of the present invention to provide a sonic head assembly and / or a sonic head of such an assembly that provides a choice of starting without the need for detaching the sonic head in the withdrawal and / or drill string in such an environment.

Another object of the present invention is to provide a sonic head assembly and / or a sonic head of such an assembly which can generate vibrations including sonic vibrations in a structure without the need for switching to the resonant frequency of the structure in which it is oscillated. According to another aspect of the present invention, starting can be started without the need for resonance, but in some embodiments such resonance can still be achieved by adjusting control variables when a sonic head assembly is used.

According to another aspect of the present invention, the object of the present invention is not to be due to eccentric rotation but to provide a sonic head and / or sonic head assembly that provides a useful sonic output that can be used in many situations or at least provides a useful choice for the public. There is.

To provide a structure of a fluid driven sonic head.

According to another aspect of the present invention, an object of the present invention is to provide separate fluid supplies, ie one providing vibration, and at least one providing control, other input variables such as amplitude, frequency, valve opening and the like. To provide a sonic head and / or sonic head assembly.

According to another aspect of the present invention, an object of the present invention is a sonic head and / or sonic head assembly having a fluid supply and return system that circulates or substantially reduces the fluid (preferably prior to return to the sonic head). To provide.

Referring to the apparatus shown in FIG. 5, there is a first variable volume chamber 30 and a second variable volume chamber 31, and flexible connectors 32 and 33, such as tires, respectively, and a portion of the shuttle 36. When connecting each piston comprising (34,35), the predicted motion amplitude is relatively small during best operation. Preferably they have a friction range of 1 mm to several cm but can be larger than the sonic head. The frequency can be from a few hertz to thousands of hertz.

Each chamber is preferably defined by the piston portion of its component 34 or 35, which includes peripheral pressure drop grooves without piston rings. This eliminates ring damage as a result of vibration and allows the supplied fluid to allow some expected lubrication effect between the piston and the respective fixed valve blocks 37 and 38. As shown, each fixed valve block 37 or 38 has a port and cooperates with each of the rotary valve members or rotary valve shafts 39 and 40 to fluid into its adjacent variable volume chamber 30 or 31. Allow the inflow of fluid from the fluid.

Within each rotary valve member 39 there is a passage in the axial direction, the ports of which are formed radially therefrom and are preferably used for the return outflow of fluid into the collection chamber, so as shown in FIG. For example by pumping). The oil inlets represent the supply through the passages to the valve device outside the rotary valve member 39 or 40.

A separate fluid supply (not shown in FIG. 5) can be operated through the member 42 and the endless driving belt or its equalizing means 43 for the respective rotary valve members 39 and 40. ) Is used. Such a hydraulic motor preferably receives a fluid supply which is provided separately from the volume of fluid supplied to provide energy to the sonic head as long as it is involved in shuttle motion.

As shown, the device, preferably comprising 41, 42 and 43, resides on a slide 44 relative to the frame 45 which directly or indirectly supports the sonic head. The frame 45 itself is arranged as a slidable carriage on the support rail or other structure 46 and can preferably operate in relation to it within the limit line.

If desired, slide 44 and rail or other structure 46 can be connected.

Selective rotation of the mandrel 47 rotates or manoeuvre the drill string attached to it, while the mandrel or its equivalent 47 is dependent upon the operation of the adjacent piston or replenishment means of the sonic head (directly or indirectly). ) Can vibrate.

Such adjacent pistons, piston assemblies, or replenishment means are preferably supported such that they are at least somewhat longitudinally movable relative to the frame 45, and several guided connectors are preferably provided for this purpose. For example, the connectors 50 and 51 on both sides of the sonic head may be connected to the sonic head by a pivot 52 or 53 and to the frame 45 by the pivot 54 or 55. At the same time preferably the compression springs 56 and 57 in cooperation with the sonic head and the frame 45 and the airbags 58 and 59 which in turn provide a cushioning and alleviating effect between the carriages or supports 44 and 46. (Or airbags) may impose limitations on movement.

Therefore, the connectors allow a similar rotation of rotation as the dog bone connectors, while at the same time allowing some axial arrangement of the sonic head as a whole, and the shuttle 36 provides for flexible drives and not shown in the accompanying drawings. Its hose and / or other connections do not limit the direct contact with the frame and / or slides or carriages 44 and 46.

Preferably all connecting means (including hydraulic pressures) are composed of flexible seismic hoses to avoid accidental disconnection.

The sonic head of the present invention can initiate the jackhammer effect without the drill string being switched for resonance. The control below may be (a) the speed of the rotary valves (rotor) and / or (b) the volume of fluid (eg oil). This changes the frequency but still allows power to be added independent of the length of the drill string. The drill string may have a defined torque and pressure without affecting the resonator or reciprocating the sonic head shuttle. This provides huge drilling control.

Systems for rotor control, independent of the shuttle oil supply system, vibration isolation of the sonic head first minimizes sonic shock, and the short distance of the frame and oil shock propagation in the frame devices confers significant advantages.

Now, an apparatus having the above-described flow capability in the operating cycle as in FIGS. 7 to 9A will be described. The device shown in Figs. 1-9A is about 1.5 m long and the shuttle motion is preferably about 0.1 mm to 15 mm (amplitude) with amplitude parameters affecting operation.

The operation may be a direct movement in the range of ms (milliseconds) in scenario A mentioned with respect to FIG. 7 (ie, FIG. 8 ', 9', etc.), but instead the scenarios of conditions such as those of FIGS. B) may require an accumulator in the oil circuit to allow for the momentary movements required at the same time in each of the following FIGS. 9 and 8.

The device according to the embodiment of the invention shown in FIGS. 10 to 13 can preferably be driven by a hydraulic system, for example from an excavator (or other delivery device or a good mobile device in standby), As such, the various resources of the pressurized fluid and reservoir referred to herein are those such as feed excavators, to which the apparatus can be connected. It is also preferred to provide hydraulic drive to any of the rotary valves independently, and to require independent discharge of the fluid instead of in each chamber end region, such pressurized fluids through closure means and / or choke valves or the like. There may be a divergence of the inflow of the device.

In the embodiment shown in FIG. 10, the piston 60 has extensions 61 fitted to allow axial movement. It is important whether the pistons and journals are not circular in cross section and / or whether they are allowed to rotate in the chamber formed by the chamber assembly 62.

As shown, any one of these openings 68 (indicated by 68A) is not connected to the chamber end region 64 through the second inlet port 66 due to a different phase condition. The pressurized fluid supply chamber 69 of the fluid supply assembly in contact with the end region 63 is opened. That is, when the first inlet port 65 is opened, the region 67 holding the second inlet port 66 is closed. The reverse is the same, and progressing situations allow for alternating charging to each chamber end region.

As shown in FIG. 10, there is a first outlet port 70 for the chamber end region 63 and a second outlet port 71 for the chamber end region 64. In the situation shown in Fig. 10, these ports are always open, preferably means other than the second rotary valve (in this case a plate with openings 72 and 73) are provided with openings 68 and ports ( It is ensured that the inflow of liquid through 65 or 66 is always at a higher speed than the outflow through the corresponding opening 72 or 73 as part of the hydraulic return circuit.

Those skilled in the art will appreciate how fluid supply assembly 74 can be provided with the supply of hydraulic fluid into chamber 69 by finding a path through which fluid is supplied into either or the other of chamber end regions 63 and 64. The apparatus in other cases drives the rotary valve 66 as preferably contemplated, for example through the outlet ports (70 and 72 and 71 and 73 in the case), for example to return to the pumping system of the excavator. It may be connected with a pumping system for the return of the same hydraulic liquid from the hydraulic motor to the chamber 69 or its bypass.

A more preferred form of the invention is shown in FIG. This embodiment is similar to the piston 75 of FIG. 10 and the extensions 76 and 77 fitted thereto, whereby openings and ratios similarly arranged in the manner shown, for example, with reference to the embodiment of FIG. 10. Chamber end regions 78 and 79 controllable by a rotary valve 80 having openings are formed. The assembly 81 with the chamber 82 is adapted to receive pressurized hydraulic liquid and to selectively allow flow to the first one and then the other of the chamber end regions 78 and 79.

The rotary valve member 83 allows the rotation of the rotary valve 80 to be timed, allowing the hydraulic liquid to flow out of the first one and then the other of the chambers 78 and 79 by varying the phase relationship of the injection, It serves to reciprocate the piston. Preferably the outflow rotary valve 83 rotates at the same speed as the rotary valve 80 and the spacings of its openings are adapted to each outlet from the chambers 78 and 79.

FIG. 11 shows the arrangement of the openings which are closed by the port 84 not being fitted with the opening 85 of the input rotary valve 80. The outlet port 85 of the same chamber end region 86 is a fluid. The opening 87 is aligned to allow the outflow to the chamber 88 of the collection assembly 89, whereby a return is carried out through the excavator, for example for reuse by a pump.

The apparatus of FIG. 13 is in the form of a bench test of an electric motor 90 (ideally a hydraulic motor in use) that directly drives a drive assembly adapted to rotate a first rotary valve (not shown). In turn, the connecting belt 91 drives another rotating valve (not shown) through the idle shaft 92 and the second connecting belt 93, thereby extending to the fitted output member 94 (piston Provide an appropriate vibration movement, caused by the reciprocation of the

Therefore, proper turning in operation can cause the required vibration. The excavator is capable of providing a substantially constant hydraulic flow and pressure with the device of the present invention and when the other flow selectively fills either side of the piston in accordance with the operation of the movement in time or synchronous with the rotary valve. If it is assumed that the supply flow is distributed to achieve rotational valve rotation, a very simple control organization applies. This would be much less complex and require less tolerance with smaller motion parts than any of the previously disclosed prior arts.

For example, if one end of the inlet port is closed by its rotary valve, the hydraulic fluid cannot flow anywhere and so will not cause work by filling into that end region. But on the other hand, if partially or completely open, the case at the other end would not be the same.

Therefore, when the input rotary valve is switched (rotated), the hydraulic oil flows into the piston chamber end region and moves the piston to its stroke end. The rotary valve continues to change over and its "consumed" hydraulic oil is discharged and discharged through its timing or synchronization with other rotary valves. At the same time or in series (or both), the first rotary valve converts oil to the other end of the piston, which in turn returns the piston.

The hydraulic drive through the timing belts means that the piston will reciprocate very slowly if the rotary valves rotate synchronously (ie 10 rpm) but the piston will move approximately 200 times per second if the two rotary valves rotate at 1000 rpm. So a simple convenience of manipulating the speed of the synchronized rotary valves can be achieved by providing a fluid input to the hydraulic motor as a transition of various basic conditions.
