Multiple boreholes are often arranged in the same well site. However, due to the limitations of site terrain and other conditions, each main hole and the corresponding multiple feather-shaped branch holes need to be drilled separately, resulting in low construction period and efficiency.

[0003] How to improve the construction efficiency of coal mine drilling and reduce the construction period of coal mine water prevention and control is an urgent problem to be solved.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] Other features and advantages of the present application will become apparent from the following detailed description, or may be learned in part by the practice of the present application.

[0007] According to one aspect of the present application, a large drilling rig overall pushing system is provided, which is used to move the large drilling rig during drilling in coal mines, and includes: a translation base, a hydraulic cylinder support, a base plate and a rotating device; the translation base includes a detachable N-section slide rail base, and the large drilling rig occupies M-section slide rail bases when it is located on the translation base, M is less than N, and M and N are both integers greater than 0; the base plate is detachably arranged under the M-section slide rail base, and the rotating device is arranged under the base plate; one end of the hydraulic cylinder support is used to be detachably connected to the base of the large drilling rig, and the other end is used to be detachably arranged on the translation base, so as to facilitate pushing and pulling the large drilling rig along the translation base.

[0027] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0028] In addition, the accompanying drawings are only schematic illustrations of the present application and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the large drilling rig integral pushing system in one embodiment of the present application may include: a translation base 1, a hydraulic cylinder support 2, a base plate 3 and a rotating device.

[0030] The translation base 1 includes N detachable slide rail bases 11. When the large drilling rig is located on the translation base 1, it occupies M slide rail bases 11, where M is less than N, and both M and N are integers greater than 0.

[0031] The base plate 3 is detachably arranged under the M-section slide rail base 11 , and the rotating device is arranged under the base plate 3 .

[0032] One end of the hydraulic cylinder support 2 is used for detachably connecting to the base of the large drilling rig, and the other end is used for detachably setting on the translation base 1, so as to facilitate pushing and pulling the large drilling rig along the translation base 1.

[0033] It should be noted that the large drilling rig integral pushing system is used to move large drilling rigs in coal mine drilling.

[0034] The embodiment of the present application does not limit the specific shape of the base plate 3. For example, the base plate 3 is in a rectangular shape.

[0035] The rotating device and the translation base 1 are respectively located on both sides of the base plate 3 . The translation base 1 is located under the large drilling rig. The base plate 3 is located under the translation base 1 . The rotating device is located under the base plate 3 .

[0036] Through the above system, the large drilling rig can be moved along the translation base, and when the large drilling rig is on the M-section slide rail base, the M-section slide rail base can be rotated by driving the base plate to rotate through the rotating device, thereby driving the large drilling rig to rotate, thereby changing the movement direction of the drilling rig, so that the drilling rig can be moved within a limited area, so that multiple feather-shaped branch holes can be cross-constructed simultaneously in the same well site with a limited area, thereby improving the construction efficiency of coal mine drilling, reducing the construction period of coal mine water prevention and control, and reducing the invalid downtime caused by drilling and grouting.

[0037] It should be noted that Figure 3 The fact that the base plate 3 is detachably arranged under the two-section slide rail base 11 is only a rational point, and M can be any positive integer.

[0038] In one embodiment, Figure 1 As shown, each section of the slide rail base 11 includes two symmetrically arranged box-block structures, the two box-block structures are connected by a plurality of cross bars, and a plurality of positioning holes 111 are evenly arranged on the slide rail of each box-block structure.

[0039] One end of the hydraulic cylinder support 2 is detachably disposed on the translation base 1 through a positioning hole 111 .

[0040] It should be noted that Figure 1 The middle translation base 1 only shows two symmetrically arranged box-block structures. In fact, the N-section slide rail base 11 included in the translation base 1 can be any integer greater than 2.

[0041] In one embodiment, Figure 2 As shown, the hydraulic cylinder support 2 includes a hydraulic cylinder 21, a cylinder support 22 and a herringbone hinge 23 which are connected in sequence.

[0042] The hydraulic cylinder 21 is used for being detachably connected to the base of the large drilling rig, and the herringbone hinge 23 is used for being embedded in the positioning hole 111 .

[0043] One end of the hydraulic cylinder 21 is connected to the large drilling rig base 5 .

[0044] In one embodiment, the hydraulic cylinder support 2 further includes: an L-shaped positioning block 24 , which is disposed on the cylinder support 22 and is used to clamp the slide rail of the slide rail base 11 .

[0045] By setting the L-shaped positioning block, the hydraulic cylinder support can be more stably set on the translation base, avoiding the floating of the hydraulic cylinder support due to pushing and pulling the large drilling rig.

[0046] In one embodiment, the rotating device includes a plurality of spiral lifting platforms.

[0047] Multiple spiral lifting platforms control their rotation angles through the same signal.

[0048] By controlling multiple spiral lifting platforms with the same signal, the consistency of the rotation angles of the multiple spiral lifting platforms can be ensured, thereby ensuring that the large drilling rig can be stably turned.

[0049] In one embodiment, the large drilling rig integral pushing system further includes: a rotation angle sensor and a controller.

[0050] The rotation angle sensor is arranged on the base plate 3 .

[0051] The controller is connected to the rotation angle sensor and controls the multiple spiral lifting platforms according to the rotation data measured by the rotation angle sensor to adjust the rotation angles of the multiple spiral lifting platforms.

[0052] By arranging a rotation angle sensor on the base plate and controlling multiple spiral lifting platforms according to data from the rotation angle sensor through a controller, the rotation of the large drilling rig can be controlled more accurately.

[0053] In one embodiment, the large drilling rig integral pushing system further includes: a vibration sensor, a hydraulic pump station and a controller.

[0054] The vibration sensor is installed on the large drilling rig.

[0055] The hydraulic pump station is connected to the hydraulic cylinder 21 of the hydraulic cylinder support 2 and controls the extension and retraction of the hydraulic cylinder 21 .

[0056] The controller is connected to the vibration sensor and the hydraulic station respectively, and sends a control signal to the hydraulic pump station according to the vibration data measured by the vibration sensor, so as to adjust the oil supply pressure provided by the hydraulic pump station to the hydraulic cylinder 21.

[0057] Using vibration sensors and controllers to control the push and pull force of large drilling rigs can effectively avoid excessive vibration of large drilling rigs, thereby better protecting the components of large drilling rigs from damage due to excessive vibration.

[0058] The embodiments of the present application do not limit where the vibration sensor is set on the large drilling rig. For example, the vibration sensor is set on a component of the large drilling rig that is easily damaged by vibration. The embodiments of the present application do not limit which component the component is. For example, the component is any connecting shaft.

[0059] In one embodiment, the large drilling rig overall moving system further includes: a gyroscope and an alarm.

[0060] The gyroscope is set on the large drilling rig.

[0061] The alarm is connected to the gyroscope and sounds an alarm when the deflection angle of the large drilling rig measured by the gyroscope is greater than a set value.

[0062] By using a gyroscope and an alarm to sound an alarm when the deflection angle of the large drilling rig is greater than a set value, the tilt angle transition during the movement of the large drilling rig can be better ensured, and the posture of the large drilling rig can be adjusted in time to ensure the stability of the large drilling rig during movement.

[0063] The embodiments of the present application do not limit where the gyroscope is disposed on the large drilling rig.

[0064] like Figure 4 As shown, one end of the hydraulic cylinder 21 is connected to the large drilling rig base 5, and the other end is embedded in the rectangular positioning holes of the left and right slide rail bases through the fishbone hinge 23 connected to the cylinder support 22. When the hydraulic pump station provides pressure to the hydraulic cylinder 21 to extend the hydraulic cylinder 21, the slide rail base 11 provides a reaction force to the large drilling rig base 5 through the positioning hole 111, thereby pushing the large drilling rig base 5 to move forward as a whole. After completing a stroke, the hydraulic cylinder 21 is retracted by reversing the operating valve of the hydraulic pump station, and the cylinder support 22 also moves forward. After the fishbone hinge 23 connected to the cylinder support 22 reaches the next positioning hole, the operation of the first stroke is repeated. This operation is repeated continuously to eventually complete the overall displacement of the entire drilling rig.

[0065] If the large drilling rig is turned only on the track, a long track is required, and the steering angle needs to be adjusted gradually, and the movement direction of the large drilling rig cannot be adjusted in a small area. During the drilling process, the large drilling rig needs to be turned in the process of moving. When turning, it is necessary to first set the base plate 3 under the predetermined M-segment slide rail base 11, and set a rotating device under the base plate 3. After the large drilling rig moves down to the M-segment slide rail base 11, the M-segment slide rail base 11 is separated from the slide rail bases 11 connected on both sides. Then, the rotation direction of the rotating device is controlled to complete the turning of the large drilling rig.

[0066] Those skilled in the art will readily appreciate other embodiments of the present application after considering the specification and practicing the invention disclosed herein. The present application is intended to cover any modification, use or adaptation of the present application, which follows the general principles of the present application and includes common knowledge or customary techniques in the art that are not disclosed in the present application.
