Description

Technical Field

[0001] This invention relates to the field of drilling rig installation technology, specifically a connection device for a split-type drilling rig used in mountainous terrain. Background Technology

[0002] Due to the complex mountainous terrain and inconvenient transportation, the modular drilling rig breaks down the power unit, operating unit, drilling unit, etc. into multiple independent modules, which are then transported to the site by manpower or small machinery and then assembled, effectively solving the transportation problem in mountainous areas.

[0003] The inefficient assembly and disassembly of existing split-type drilling rigs is a significant problem. Traditional connections often use flange bolts or pins, requiring multiple people to work together during installation. Hole alignment is difficult, and specialized tools are needed for repeated tightening, making a single assembly take several hours. In mountainous operations requiring frequent relocation, this inefficient assembly and disassembly process severely hinders construction progress.

[0004] Mountain drilling rigs are subjected to intense impact loads and alternating stresses during drilling. Traditional threaded connections are prone to loosening under vibration, leading to connection failure. Existing connection structures have gaps at the joints, which can loosen over time, affecting equipment stability and drilling accuracy. Furthermore, the rainy and foggy mountain environment often neglects the sealing and protection of connection interfaces, allowing moisture and dust to penetrate and cause corrosion and jamming of connecting parts, further increasing the risk of connection failure.

[0005] The existing connection device only performs mechanical connection functions and cannot achieve synchronous connection and adjustment of hydraulic circuits. When drilling parameters need to be adjusted to adapt to different rock formation conditions, operators have to stop the machine and manually adjust the oil circuit valves, which not only affects drilling efficiency but also makes it difficult to guarantee adjustment accuracy.

[0006] Therefore, there is an urgent need in this field for an innovative connection device specifically designed for mountain split-type drilling rigs, which can enable rapid assembly and disassembly between modules and comprehensively improve the safety and operational efficiency of split-type drilling rigs in complex mountainous conditions.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Figures 1-7As shown, the present invention provides a technical solution for a connection device of a split-type drilling rig for mountain use. The connection device of the split-type drilling rig for mountain use includes a drive module 1, a quick-release male connector 2 installed at the bottom of the drive module 1, a connecting seat 3 circumferentially arranged on the outer side of the quick-release male connector 2, a rotary plug 21 rotatably connected inside the quick-release male connector 2, the drive module 1 is connected to an execution module 4, a quick-release female connector 5 is provided at the top of the execution module 4, a connecting seat 3 is also circumferentially arranged on the outer side of the quick-release female connector 5, a vibration damping component 6 is installed between the quick-release male connector 2 and the connecting seat 3 on the quick-release female connector 5, a positioning component 7 is installed on the execution module 4, and an angle adjustment component 8 is also installed on one side of the execution module 4; a hoisting frame 11 is provided at the top of the drive module 1, a hydraulic pump 12 is installed on the drive module 1, and an oil pipeline 13 is provided on the drive module 1.

[0024] Steel balls 5501 are embedded in several conical grooves 55 arranged around the quick-release female head 5. The conical grooves 55 are connected to the slots 51, and the opening of the conical grooves 55 closer to the slots 51 is smaller. Therefore, the steel balls 5501 extend into the slots 51 but do not enter the slots 51. When the pressing spring 5401 is at its original length, the boss 5601 of the pressing member 56 can block the opening on the outside of the conical grooves 55, thereby limiting the position of the steel balls 5501.

[0025] When the drive module 1 is connected to the execution module 4, the quick-release male connector 2 needs to be inserted into the quick-release female connector 5. During the connection process, the pressing component 56 needs to be moved to move the boss 5601 above the conical groove 55, ensuring that the steel ball 5501 is in an active state. When the rotary plug 21 is inserted, the steel ball 5501 will be embedded in the locking groove 2103, and the steel ball 5501 will make a sound after being embedded, reminding the operator that the steel ball 5501 has moved to the designated position. Then, the pressing component 56 is released, and the pressing component 56 returns to the initial position under the restoring force of the pressing spring 5401. The boss 5601 blocks the opening on the outside of the conical groove 55 again, so that the steel ball 5501 is fixed again. At this time, the rotary plug 21 is locked by the steel column 5501, thus completing the quick connection between the drive module 1 and the execution module 4.

[0026] In addition to enabling quick connection of different functional modules, the quick-release male connector 2 and quick-release female connector 5 also connect the circuit and oil circuit simultaneously. A conductive ring 2102 is provided on the end face of the rotary plug 21. When the rotary plug 21 is inserted into the slot 51, the conductive ring 2101 will be embedded in the conductive groove 5101 at the bottom of the slot 51, realizing the connection of the circuit of the split drilling rig. This connection method can avoid poor circuit contact caused by inaccurate positioning. An oil circuit 23 is provided in the middle of the rotary plug 21. When the rotary plug 21 is inserted into the slot 51, the oil inlet channel 52 is inserted into the stepped groove 2301 at the end of the oil circuit 23, completing the connection of the oil circuit. Through the cooperation of the quick-release male connector 2 and quick-release female connector 5, in addition to realizing the quick disassembly and assembly of functional modules, the circuit and oil circuit can also be connected simultaneously, which greatly improves the installation efficiency of the split drilling rig.

A bevel gear 5302 is provided at one end of the rotating shaft 5301.

[0029] The quick-release female head 5 has a pressing groove 54 on its outer wall, and a pressing spring 5401 is installed in the pressing groove 54. The bottom of the pressing groove 54 has a tapered groove 55 evenly distributed, and a steel ball 5501 is placed in the tapered groove 55. A pressing member 56 is sleeved on the outer side of the quick-release female head 5. A boss 5601 is provided on the inner side of the pressing member 56. The boss 5601 is embedded in the pressing groove 54. The pressing spring 5401 is located between the pressing groove 54 and the boss 5601. A sealing ring 5602 is provided on the contact surface between the pressing member 56 and the pressing groove 54.

[0030] The vibration damping component 6 includes a damper 61 and a vibration damping spring 62 sleeved on the outside of the damper 61. A stud 6101 is provided at one end of the damper 61, and an adjusting ring 6102 is sleeved on the stud 6101. One end of the vibration damping spring 62 is connected to the adjusting ring 6102, and the other end of the vibration damping spring 62 is fixed. After the split-type drilling rig is connected, in order to improve the vibration damping performance of the drilling rig, multiple sets of vibration damping components 6 can be installed between the quick-release male head 2 and the quick-release female head 5. One end of the vibration damping component 6 is connected to the connecting seat 3 on the outer wall of the quick-release male head 2, and the other end of the vibration damping component 6 is connected to the quick-release female head 5. The outer wall is connected by a connecting seat 3, and the two connecting seats 3 on both sides are located in the same vertical direction to ensure that all installed damping components are set in parallel. The damping component 6 includes a damper 61, an adjusting ring 6102 is fitted on the damper 61, and a damping spring 62 is fitted on the outer side of the damper 61. A stud 6101 is provided on the outer side of the damper 61. By rotating the adjusting ring 6102, it moves along the damper 61, thereby changing the distance between the adjusting ring 6102 and the connecting seat 3, thereby adjusting the length of the damping spring 62 and changing the damping capacity of the damping component 6.

[0031] The execution module 4 includes a connecting platform 41. The outer wall of the connecting platform 41 is symmetrically provided with hanging ears 4101. The bottom of the connecting platform 41 is provided with a telescopic rod 42. The bottom of the telescopic rod 42 is provided with a connecting part 4201. A connecting frame 43 is installed below the connecting platform 41. Both ends of the connecting frame 43 are provided with hydraulic push rods 4301. The other end of the hydraulic push rod 4301 is fixedly connected to the connecting part 4201.

[0032] The positioning component 7 includes a positioning sleeve 71, which is used to fix the drill bit. Connecting rods 72 are provided on both sides of the positioning sleeve 71, and the other end of the connecting rods 72 is connected to the lug 4101.

[0033] An angle adjustment component 8 is installed on the outside of the connecting frame 43. The angle adjustment component 8 includes a mounting plate 81 that is rotatably connected to the connecting frame 43. An adjustment rod 82 is installed between the connecting frame 43 and the mounting plate 81.

[0034] The end of the oil inlet channel 52 is connected to the hydraulic push rod 4301, and the hydraulic oil in the oil delivery pipe 13 eventually enters the hydraulic push rod 4301.

[0035] Working principle of the invention: Steel balls 5501 are embedded in several conical grooves 55 arranged around the quick-release female head 5. The conical grooves 55 are connected to the slots 51, and the opening of the conical grooves 55 closer to the slots 51 is smaller. Therefore, the steel balls 5501 extend into the slots 51 but do not enter the slots 51. When the pressing spring 5401 is at its original length, the boss 5601 of the pressing member 56 can block the opening on the outside of the conical grooves 55, thereby limiting the position of the steel balls 5501.

[0036] When the drive module 1 is connected to the execution module 4, the quick-release male connector 2 needs to be inserted into the quick-release female connector 5. During the connection process, the pressing component 56 needs to be moved to move the boss 5601 above the conical groove 55, ensuring that the steel ball 5501 is in an active state. When the rotary plug 21 is inserted, the steel ball 5501 will be embedded in the locking groove 2103, and the steel ball 5501 will make a sound after being embedded, reminding the operator that the steel ball 5501 has moved to the designated position. Then, the pressing component 56 is released, and the pressing component 56 returns to the initial position under the restoring force of the pressing spring 5401. The boss 5601 blocks the opening on the outside of the conical groove 55 again, so that the steel ball 5501 is fixed again. At this time, the rotary plug 21 is locked by the steel column 5501, thus completing the quick connection between the drive module 1 and the execution module 4.

[0037] In addition to enabling quick connection of different functional modules, the quick-release male connector 2 and quick-release female connector 5 also connect the circuit and oil circuit simultaneously. A conductive ring 2102 is provided on the end face of the rotary plug 21. When the rotary plug 21 is inserted into the slot 51, the conductive ring 2101 will be embedded in the conductive groove 5101 at the bottom of the slot 51, realizing the connection of the circuit of the split drilling rig. This connection method can avoid poor circuit contact caused by inaccurate positioning. An oil circuit 23 is provided in the middle of the rotary plug 21. When the rotary plug 21 is inserted into the slot 51, the oil inlet channel 52 is inserted into the stepped groove 2301 at the end of the oil circuit 23, completing the connection of the oil circuit. Through the cooperation of the quick-release male connector 2 and quick-release female connector 5, in addition to realizing the quick disassembly and assembly of functional modules, the circuit and oil circuit can also be connected simultaneously, which greatly improves the installation efficiency of the split drilling rig.

[0038] After the split-type drilling rig is connected, in order to improve the vibration reduction performance of the drilling rig, multiple sets of vibration damping components 6 can be installed between the quick-release male head 2 and the quick-release female head 5. One end of the vibration damping component 6 is connected to the connecting seat 3 on the outer wall of the quick-release male head 2, and the other end of the vibration damping component 6 is connected to the connecting seat 3 on the outer wall of the quick-release female head 5. The positions of the connecting seats 3 on both sides are located in the same vertical direction to ensure that all installed vibration damping components are set in parallel. The vibration damping component 6 includes a damper 61, an adjusting ring 6102 is sleeved on the damper 61, and a vibration damping spring 62 is sleeved on the damper 61. A stud 6101 is provided on the outside of the damper 61. By rotating the adjusting ring 6102, it moves along the damper 61, thereby changing the distance between the adjusting ring 6102 and the connecting seat 3, thereby adjusting the length of the vibration damping spring 62 and changing the vibration damping capacity of the vibration damping component 6.

[0039] The hydraulic pump 12 on the drive module 1 provides power for the movement of hydraulic oil. The hydraulic oil passes through the oil supply pipe 13, oil circuit 23 and oil inlet channel 52 in sequence, and finally enters the hydraulic push rod 4301 to drive the movement of the telescopic rod 42. A valve core 53 is provided in the oil inlet channel 52, which can control the opening size of the oil inlet channel 52, thereby adjusting the working frequency of the hydraulic push rod 4301. The adjustment of the valve core 53 can be achieved by rotating the plug 21. Since the oil inlet channel 52 is partially embedded in the stepped groove 2301 in the middle of the rotating plug 21, and the annular bevel teeth 2302 provided in the stepped groove 2301 mesh with the bevel gear 5302 on the valve core 53, by rotating the rotating plug 21, the valve core 53 can be driven to rotate synchronously, thereby adjusting the flow rate of the oil inlet channel 52.

[0040] This invention enables the rapid connection of split-type drilling rigs through the cooperation of quick-release male head 2 and quick-release female head 5. The connection device not only has vibration damping pads 2201 installed on the contact surface, but also has multiple sets of vibration damping components 6 on the outside of the connection device, which can achieve multi-directional vibration damping. Through multiple sets of dampers 61, various forms of vibration energy during drilling rig operation can be offset, thereby protecting the connection components and preventing the drilling rig joint from loosening due to continuous vibration, causing component damage, oil leakage and other problems.

[0041] After the quick-release male connector 2 is inserted into the quick-release female connector 5, in addition to connecting different functional modules of the drilling rig, it can also connect the internal circuit and oil circuit 23 of the drilling rig, eliminating most of the installation steps. The split-type drilling rig can be disassembled and assembled simply by moving the pressing part 56, which greatly improves the installation efficiency of the split-type drilling rig.

[0042] Once the split-type drilling rig is connected, the opening size of the valve core 53 inside the oil passage 23 can be adjusted synchronously by rotating the rotary plug 21, thereby controlling the flow rate of the internal oil passage 23 and adjusting the drilling efficiency in real time.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
