Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not intended to limit scope of the present utility model.
As Figure 1-3, this utility model provides a kind of hydraulic machine double acting pressurized coring tool, it includes top connection 1, six square bar 3, six square set 2, pressurization lower contact 7, tap 13, inner core 17, core grabber 18, safety collar 11, single-direction balls 14 and ball seat 15；
Described top connection 1 top is connected with drilling tool by screw thread, and its underpart is connected by screw thread and six square bars 3, and described six square sets 2 are internal is hexagon, and it is outside that it is enclosed within six square bars 3, coordinates with six square bars 3, and described six square bars 3 can slide in six square sets 2；
Described six square set 2 bottoms are connected with pressurization lower contact 7 by screw thread；
Described pressurization lower contact 7 is internal is sequentially installed with spring 6, pressure rod 4 and jump ring 5；
Described pressurization lower contact 7 bottom is connected by screw thread with the big joint 8 of coring tool；
Described tap 13, inner core 17 and core grabber 18 are threaded successively, hang on big joint 8 by hanging pin 9, hang 9 and fix with pin stifled 10；
It is outside that described safety collar 11 is fixed on tap 13 by safety pin 12, and it is internal that ball seat 15 is threadedly attached in tap 13, is provided with aperture in the middle part of described ball seat 15, and described single-direction balls 14 blocks the aperture in the middle of ball seat 15；
Described big joint 8 is outside to be connected with urceolus 16 by screw thread, and urceolus 16 bottom is connected with core bit 19 by screw thread.
In process of coring, the state of instrument is as shown in Figure 1, six square sets 2 are together with top connection 1 also, rotate and transfer drilling tool and start core-drilling, after creeping into end, ground puts into 4 pressurizing balls 20, lifts up certain distance, six square bars 3 are made to slide in six square sets 2, six square sets 2 and top connection 1 disengage, and pressurizing ball 20 falls pressure rod top, as shown in Figure 2.Transfer drilling tool, six square bars 3 are descending gradually, by steel ball, are pressed on pressure rod 4, overcome acting force of the spring, pressing under continuing, pressure rod 4 is descending, when going downwards to ball seat 15, circulation canal is closed, now turn on pump continue to transfer drilling tool, drilling tool pressure and pump pressure act simultaneously on ball seat, promote ball seat descending.Ball seat drives tap to cut off suspension pin, and inner core and core grabber are descending.Continuing pressure drilling tool turn on pump down to build the pressure, core grabber draws core breaking 21 in.Lifting up drilling tool, six square bars 3 slide up in six square sets 2, and pressure rod 3 is up under the action of the spring, and circulation canal is opened.If there is the situation that circulation canal can not be opened, continuing the certain pressure that builds the pressure, cut off safety pin 12, safety collar 11 is descending, and another circulation canal is opened, and completes coring operation.
Hydraulic machine double acting pressurized coring tool provided by the invention, there is mechanical pressurization and the advantage of fluid power two kinds of instruments of pressurization, it is possible to be used alone mechanical pressurization, if mechanical pressurization power is not enough, can again turn on pump build the pressure realization machinery and fluid power pressurize simultaneously, improve cut heart success rate.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
