Definitions
- the invention relates to a method for operating a Work module, in particular a hydraulic gripper, which when drilling a borehole with a power turret and a drill pipe to remove obstacles, for example of rock, boulders etc. becomes.
- a gripper tool for example a hydraulic gripper, which with an additional device for the gripper tool is operated.
- the additional device must be provided at the borehole will.
- the invention has for its object to provide a method for operating a work module, such as a hydraulic gripper, and a device which make drilling and removing obstacles in a borehole extremely efficient in terms of equipment and in terms of time and costs.
- a work module such as a hydraulic gripper
- the task is procedurally characterized by the features of the claim 1 and device-wise by the features of the claim 6 solved.
- An essential basic idea of the invention is to use a tool that is designed in this way is that mechanical quantities, namely torque M and speed n, for example a turret with drill pipe, optionally and for a definable period of time in converts hydraulic power.
- any hydraulically actuated module can be used as the work module Unit or device or tool can be used.
- Method and device is the transfer of Torque and speed of a rotary head with a Kelly rod viewed in a hydraulic gripper as a work module. Speed and torque of the Kelly bar are with an additional work tool on the hydraulic gripper transfer.
- the work equipment is designed in this way and arranged between the drill pipe and hydraulic gripper, that speed and torque by changing the direction of rotation is converted into hydraulic power. This hydraulic Performance is at least the hydraulic gripper to exercise another function.
- the supply of the locking cylinders of the hydraulic gripper is essential with hydraulic fluid using a Hydraulic pump driven by the drill pipe becomes.
- the hydraulic head which is connected to the drill pipe, the rotary movements the drill pipe onto the work module, e.g. on the Hydraulic gripper, transmits.
- the open gripper blades can be placed on the bottom of the borehole be turned into the ground.
- the hydraulic head has Gearbox on which the speed of the drill string around increases a factor i and at the same time the torque of the Drill pipe reduced by the same factor.
- a freewheel is arranged for the transmission and the hydraulic pump, which is a speed transfer into the hydraulic pump allows in a first direction of rotation, but in the opposite direction of rotation locks.
- Grab blades in a direction of rotation of the drill pipe be turned into the ground.
- the hydraulic pump is driven in the direction of rotation and hydraulic cylinder of the work module actuated, in which Hydraulic fluid from the hydraulic pump into the hydraulic cylinder is promoted.
- a directional valve is provided to open the gripper blades, which has a toggle function to reverse the Hydraulic fluid flow is assigned.
- the work module or the hydraulic gripper with rock etc. is filled, it is attached to the drill pipe promoted the surface. It is advantageous if the hydraulic gripper pulled against a stop on the power turret can be. This is due to the tractive forces exerted Directional control valve switched accordingly and the rotary movement of the Drill pipe in hydraulic energy to open the grab buckets transformed.
- the working means according to the invention between an aggregate, whose torque and speed is transmitted, for example a power turret, and a work module, for example a drilling gripper module, is for hydraulic consumers in the broadest sense.
- a work module for example a drilling gripper module
- Gripper module or hydraulic gripper can also be hydraulic driven pumps, hammer mechanisms or motors via a rotary drive with circumferential and contact pressure and moved hydraulically by changing the direction of rotation, be pivoted, for example.
- Fig. 1 shows a hydraulic head 3, which as a working medium hydraulic power from over a drill pipe 2 mechanical quantities led to a borehole bottom, the Torque M and the speed n of the drill string 2, generated.
- the drill pipe 2 is non-rotatable with a power turret (not shown), which represents an aggregate 2, its torque M and speed n transferred and in hydraulic Power to be converted, connected.
- the hydraulic head 3 has a rotationally fixed with a coupling piece of the drill pipe 2 connected head cover 21st on which there is a head housing via a bearing unit 31 17 connects. With the rotating head housing 17 are connected a gear 7, a freewheel 11 and one Hydraulic pump 9, which are surrounded by the head housing 17.
- a switch housing 15, which has a switching element on the bottom, e.g. a spring-biased switch cam 16 and surrounds the head housing 17 to which it is connected in a rotationally fixed manner is via a work module 5 (see FIGS. 4 and 5), which stands on a borehole bottom (not shown), held non-rotatably.
- the transmission 7 which for example can be designed as a planetary gear, and having a gear ratio i reduces the input torque M by 1 / i times and increases the input speed n by the same factor i.
- the transmission output shaft 23 drives via a clutch 13 a drive shaft 24 of the freewheel 11, which at the first Direction of rotation torque M and speed n unaffected via a clutch 14 to a drive shaft of the hydraulic pump 9 passes on.
- the hydraulic pump 9 sucks out a hydraulic fluid a tank 27 and transmits speed and torque in volume flow and pressure.
- the hydraulic fluid is on the High-pressure side of the hydraulic pump 9 via a hydraulic line 18 to a valve 20, for example a 4/2-way valve to the hydraulic consumer, in this case to hydraulic cylinders 6 of the hydraulic gripper 5 (see FIG. 4 and 5) directed.
- a hydraulic return line 19 and the directional control valve 20 is guided back into the tank 27.
- a second and opposite direction of rotation Direction of rotation of the drill pipe 2 can rotate on the work module 5 are transmitted when the freewheel 11 in the second direction of rotation is blocked, i.e. a freewheel inner part 12 and one rigidly connected to the head housing 17 Freewheel outer ring 10 are coupled together.
- An output shaft 25 of the freewheel 11 can with respect to the Head housing 17 no longer exercise relative rotation, whereby the transmission output shaft 23 with 1 / i-fold drill pipe torque is held. Speed and torque transmitted to the head housing 17 via the gear housing 7, which is rotatably connected to the switch housing 15 is.
- the work module 5 firmly connected to the switch housing 15 is now with the torque and speed of the drill string 2 driven so that in this second direction of rotation the open gripper blades 4 (see FIGS. 4 and 5) in the bottom of a borehole can be rotated.
- Switch housing 15 with spring-loaded switching cam 16 offers the possibility of two different flow directions to realize the hydraulic fluid without the work module, for example a hydraulic gripper, and the hydraulic head 3 from a borehole for switching purposes must be transported out.
- the two different ones Directions of hydraulic fluid are reached when an additional load on the Hydraulic head 3 can be abandoned.
- the switch housing 15 is provided with a spring device 16 and enables Relative movements to the drill pipe 2, which for Circuit of the directional valve 20 can be used.
- the Switching of the directional valve 20 as a function of a load is apparent from Fig. 2. In this position the hydraulic gripper 5 (not shown) on the The bottom of the borehole and the drill pipe 2 will be loaded the switch housing 15 is exerted, whereby the directional control valve 20 switched and the direction of flow of the hydraulic fluid is turned over.
- Fig. 3 shows a further switching state.
- tensile forces act on the switch housing 15, which compared to the state of FIGS. 1 and 2 up to a cover-side stop 33 towards the bottom of the borehole is adjusted.
- This adjustment comes from the spring device 16 out.
- Hydraulic actuation of the hydraulic cylinders 6, of which only one cylinder is shown is done when the switch housing 15 and with this the work module 5 against a stop, for example pulling the turret (not shown), so that with simultaneous rotation of the drill pipe in Direction of rotation 2 the gripper blades 4 opened hydraulically will.
- a particularly simple variant of the Hydraulic head without switching housing 16 may be formed. It is then only a direction of flow of the hydraulic fluid possible. A second possibility would then exist therein, the work module 5 outside the borehole, for example by manual adjustment.
- FIGS. 1 to 3 show a preferred embodiment Device for transmitting the rotational energy of a Power rotary head using drill pipe 2 in a hydraulic gripper 5. Training and arrangement of the hydraulic head 3 corresponds to FIGS. 1 to 3. The same features were with provided identical reference numerals.
- Fig. 5 shows a second variant of an inventive Device with drilling gripper module 5, 3.
- the hydraulic head 3 is only shown in outline. Below the hydraulic head 3 are the hydraulic cylinders 6 in axial extension arranged.
- the hydraulic gripper 5 with its gripper blades 4 is also shown in the open position. 5 illustrates the non-rotatable arrangement of the hydraulic gripper 5 on the hydraulic head 3.
