[0033] Embodiment 1

[0034] like Figures 1 to 7As shown, a drilling rig according to an embodiment of the present invention comprises a lifter 1, a manipulator 2 and a moving mechanism, wherein the lifter 1 comprises a cylindrical body 101 and a locking ring 102 which is movably mounted on the outside of the cylindrical body 101, the manipulator 2 comprises a mounting seat 201 and a clamping mechanism, a lifting mechanism and a telescopic mechanism connected thereto, the clamping mechanism and the lifting mechanism are connected to the telescopic mechanism, the telescopic mechanism is used to drive the clamping mechanism and the lifting mechanism to approach or move away from the mounting seat 201, the clamping mechanism is used to clamp and fix the cylindrical body 101, the lifting mechanism is used to move the locking ring 102 up and down, and the moving mechanism is used to drive the lifter 1 and the mounting seat 201 to move up and down. The present embodiment is to load and unload the lifter 1 and the drill rod 3 by setting a manipulator 2, and the lifter 1 and the manipulator 2 are moved into the air by the moving mechanism, and the clamping mechanism of the manipulator 2 clamps and fixes the lifter 1, and then the locking ring 102 sleeved on the outside of the cylindrical body 101 is lifted by the lifting mechanism of the manipulator 2, and then the lifter 1 is moved by the telescopic mechanism, so that the drill rod 3 is embedded in the lifter 1 from the side of the lifter 1, and then the lifting mechanism of the manipulator 2 lowers the locking ring 102 of the lifter 1, and the locking ring 102 falls down to fix the lifter 1 and the drill rod 3, completing the connection between the lifter 1 and the drill rod 3. When disassembling, the clamping mechanism clamps and fixes the lifter 1, and then the locking ring 102 is moved upward by the lifting mechanism to loosen the connection between the lifter 1 and the drill rod 3, and then the lifter 1 is moved by the telescopic mechanism, and the drill rod 3 is disengaged, and the disassembly is completed without the need for operators to perform high-altitude operations, which is safe, reliable, easy and convenient.

[0035] like Figure 7As shown, the clamping mechanism includes a first clamping arm 202, a second clamping arm 203 and a driving device, wherein the first clamping arm 202 is arranged at one side of the second clamping arm 203, and the driving device is used to drive the first clamping arm 202 to approach or move away from the second clamping arm 203. The clamping mechanism of this embodiment also includes a movable rod 204 and a moving block 205, and the driving device is a clamping motor 206. The first end of the first clamping arm 202 is hinged to the second clamping arm 203, the first end of the movable rod 204 is hinged to the second end of the first clamping arm 202, the second end of the movable rod 204 is provided with a long hole 207, the moving block 205 can be slidably mounted in the long hole 207, and the moving block 205 is connected to the protruding end of the clamping motor 206. When the extended end of the clamping motor 206 is extended, it drives the moving block 205 to move in the long hole 207, and then drives the second end of the movable rod 204 to move, and at the same time drives the movable rod 204 to rotate around the hinge between it and the first clamping arm 202. The movable rod 204 pushes the first clamping arm 202 to rotate around the hinge between it and the second clamping arm 203, so that the opening between the first clamping arm 202 and the second clamping arm 203 is enlarged, so that the lifter 1 enters between the first clamping arm 202 and the second clamping arm 203, and then, the clamping motor 206 is retracted, pulling the movable rod 204, and then tightening the first clamping arm 202, so that the lifter 1 is clamped between the first clamping arm 202 and the second clamping arm 203. The operation is simple and adapts to the cylindrical shape of the lifter 1. Furthermore, a bayonet 208 that cooperates with the cylindrical body 101 is formed between the first clamping arm 202 and the second clamping arm 203, and a positioning block 103 is provided on the cylindrical body 101. A positioning groove 209 that engages with the positioning block 103 is provided on one side of the bayonet 208. When the lifter 1 is clamped, due to the cylindrical body 101 of the lifter 1, the first clamping arm 202 will drive the cylindrical body 101 to rotate when it contacts and leaves the cylindrical body 101. Therefore, the orientation of the lifter 101 can be positioned. When the positioning block 103 on the cylindrical body 101 is engaged with the positioning groove 201, the side opening of the lifter where the drill rod is embedded is directed outward to prevent the opening from being blocked by the clamping arm, thereby preventing the drill rod 3 from being unable to be embedded in the cylindrical body 101.

[0036] like Figure 6As shown, the lifting mechanism of this embodiment includes a lifting arm 210 and a lifting motor 211. The lifting arm 210 is connected to the protruding end of the lifting motor 211. The lifting arm 210 of this embodiment is a block. The lifting arm 210 is used to abut against the locking ring 102. When the lifter 1 and the drill rod 3 are connected, the lifting arm 210 is located below the locking ring 102. The lifting motor 211 moves the lifting arm 210 upward, thereby driving the locking ring 102 located above the lifting arm 210 to move upward, so that the drill rod 3 can enter the cylindrical body 101 from the side of the cylindrical body 101, and then the lifting motor 211 moves the lifting arm 210 downward, the locking ring 102 loses support, and the locking ring 102 falls, thereby firmly connecting the lifter 1 and the drill rod 3; when disassembling, the lifting arm 210 moves to the bottom of the locking ring 102, and then the lifting motor 211 moves the lifting arm 210 upward, driving the locking ring 102 to move upward, thereby disconnecting the firmly connected lifter 1 and the drill rod 3. The lifting arm 210 of this embodiment can be a ring block with one side open, so as to evenly apply pressure to the lock ring 102. In addition, in this embodiment, the telescopic mechanism includes a telescopic motor 212, which is connected to the mounting seat 201, and the clamping mechanism and the lifting mechanism are connected to the extended end of the telescopic motor 212. In this embodiment, the first clamping arm 202, the second clamping arm 203, the clamping motor 206 and the lifting motor 211 are connected to the extended end of the telescopic motor 212.

[0037] like Figure 1 , Figure 2 and Figure 3As shown, the drilling rig of this embodiment also includes a drilling rig body 4, and the moving mechanism includes a manipulator moving mechanism. The manipulator moving mechanism includes a first mounting frame 5, the first mounting frame 5 is connected to the drilling rig body 4, and the mounting seat 201 is connected to the first mounting frame 5 so as to be movable up and down. The mounting seat 201 of this embodiment is embedded in the middle of the first mounting frame 5. A moving motor 6 is provided at the bottom of the first mounting frame 5 of this embodiment, and the mounting seat 201 is connected to the protruding end of the moving motor 6. The moving motor 6 drives the mounting seat 201 to move up and down. A plurality of placement cups 7 for placing drill rods 3 are provided on the drilling rig body 4, and the plurality of placement cups 7 and the first mounting frame 5 are arranged in a straight line. The placement cups 7 can fix the drill rod 3, and the placement cups 7 and the first mounting frame 5 are arranged in a straight line, so that after the clamping mechanism of the manipulator 2 grasps the lifter 1, the lifter 1 is directly moved forward to the drill rod 3 through the telescopic mechanism of the manipulator, and there is no need to set a steering mechanism to align the lifter 1 with the drill rod 3, thereby simplifying the structure and simplifying the moving path of the manipulator. In addition, the drill body 4 is provided with a retaining frame located on one side of the placement cup 7, the retaining frame includes two columns 8 and a crossbeam 9 straddling the two columns 8, the crossbeam 9 is located above the placement cup 7, and a plurality of rollers 10 are connected to the crossbeam 9, the arrangement direction of the plurality of rollers 10 is parallel to the arrangement direction of the placement cup 7, and one roller 10 is located between two adjacent placement cups 7. When the drill rod 3 falls accidentally, the retaining frame protects the personnel on the drill body 4. When the drill rod 3 is built into the placement cup 7, the roller 10 is located between two adjacent drill rods 3, which can maintain the interval between the drill rods 3 and facilitate the removal and placement of the drill rods 3.

[0038] like Figure 1 and Figure 2 As shown, the moving mechanism of this embodiment includes a lifter moving mechanism, and the lifter moving mechanism includes a second mounting frame 11 and a pulley 12. A moving rod 13 is provided at the top of the second mounting frame 11. The second mounting frame 11 is located on one side of the placement cup 7. The moving rod 13 is perpendicular to the arrangement direction of the placement cup 7. The pulley 12 is movably connected to the moving rod 13. The pulley 12 of this embodiment is hinged at the end of the moving rod 13. The lifter 1 is connected to the pulley 12 through a transmission line 14 to prevent the lifter moving mechanism from being blocked between the drill rod 3 and the manipulator 2, effectively completing the working conversion of the lifter 1 and the drill rod 3 between the drill rod working position and the placement position, and preventing the lifter 1 from shaking and causing it to collide with the manipulator 2 when the lifter 1 is lifted by the transmission line 14 and the pulley 12.

[0039] In addition, the manipulator 2 of this embodiment is provided with a monitoring device, which can observe the loading and unloading of the lifting device 1 and the drill rod 3 by the manipulator 2 in real time. In addition, the drilling rig also includes an operating device, which is controlled and connected with the moving mechanism, the clamping mechanism, the lifting mechanism, the telescopic mechanism, and the monitoring device.

The moving motor 6, the telescopic motor 212, the clamping motor 206, and the lifting motor 211 are controlled by the operating device to extend or retract to control the movement, clamping, and release of the manipulator. The operating table of this embodiment can be operated manually.

[0040] The working process of the present invention is as follows: control the moving motor 6 to raise the manipulator 2; pull the transmission line 14 to raise the lifter 1, and the pulley 12 drives the lifter 1 to move to the front of the manipulator 2; the extended end of the telescopic motor 212 of the manipulator 2 extends, and the clamping mechanism and the lifting mechanism are moved forward until the cylindrical body 101 of the lifter 1 is located between the first clamping arm 202 and the second clamping arm 203. The first clamping arm 202 and the second clamping arm 203 of this embodiment clamp the part of the cylindrical body 101 below the locking ring 102, so that the lifting arm 210 of the lifting mechanism is located below the locking ring 102. The positioning block 103 of the lifting device 1 is controlled to be engaged in the positioning groove 209, and the clamping motor 206 remains in the extended state; the extended end of the lifting motor 211 is retracted, driving the lifting arm 210 to move upward, thereby driving the locking ring 102 to move upward; the extended end of the telescopic motor 212 continues to extend until the drill rod 3 enters the lifting device 1 from the side of the lifting device 1; the extended end of the lifting motor 211 is extended or the extended end of the telescopic motor 212 is retracted, the locking ring 102 loses its support, and the locking ring 102 falls freely, thereby realizing a stable connection between the lifting device 1 and the drill rod 3; conversely, the lifting device 1 and the drill rod 3 can also be disassembled.

[0043] In addition, the structure of the lifting arm 210 in the lifting mechanism of the present embodiment is the same as the clamping mechanism of the present embodiment.

The sliding rod 22 is sleeved in the sliding rod hole 23 to guide the up and down movement of the lifting arm 210 and prevent the lifting arm 210 and the second clamping arm 203 from rotating.

[0045] In this embodiment, the clamping mechanism and the lifting mechanism move to the lifter 1, the first electromagnet 15 and the second electromagnet 19 work, so that the first clamping arm 202 and the second clamping arm 203 clamp and grasp the bottom of the lifter 1, and the fixed plate 17 and the movable plate 18 clamp and grasp the locking ring 102. When installing the lifter 1 and the drill rod 3, the lifting motor 211 drives the lifting arm 210 to move up first and then down. When disassembling the lifter 1 and the drill rod 3, the lifting motor 211 drives the lifting arm 210 to move up.

[0046] The other structures of this embodiment are the same as those of the first embodiment and will not be described again here.
