For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0027] See also Figure 1-3 As shown, this embodiment provides a remote-controlled full-casing full-rotation drilling rig, including: a casing 100 and a drill bit 111 that can rotate and move up and down, a detection component for detecting the verticality of the casing 100, and an adjustment component for adjusting the verticality of the casing 100.
[0028] The adjustment assembly includes multiple first adjustment units 141 and multiple second adjustment units 142 located on the ground, the first adjustment units 141 are arranged along the circumference of the casing 100, the second adjustment units 142 are located at the top of the casing 100, and the output end of the first adjustment unit 141 is set toward the casing 100, and the output end of the second adjustment unit 142 is connected to the top of the casing 100.
[0029] The detection component and the adjustment component are both electrically connected to the controller.
[0030] It can be seen that the detection component is used to monitor the verticality of the casing 100 in real time to ensure that the casing 100 always remains in a vertical state during drilling, thereby improving the drilling accuracy of the drill bit 111; the adjustment component includes a plurality of first adjustment units 141 and a plurality of second adjustment units 142, the first adjustment unit 141 is arranged along the circumference of the casing 100, and can be fine-tuned according to the verticality of the casing 100 to keep the casing 100 always in a vertical state, the second adjustment unit 142 is located at the top of the casing 100, connected to the top of the casing 100, and the verticality of the casing 100 can be adjusted by adjusting the position of the output end; the detection component and the adjustment component are both electrically connected to the controller, and can monitor the verticality of the casing 100 in real time, and adjust the first adjustment unit 141 and the second adjustment unit 142 as needed, which helps to improve the overall performance of the drilling rig.
[0031] It can be understood that the remote-controlled full-casing and full-rotation drilling rig provided in this embodiment has significant advantages in ensuring the precise drilling of the drill bit 111; by setting multiple first adjustment units 141 and multiple second adjustment units 142, the adjustment process can be more efficient and accurate; by real-time monitoring of the verticality of the casing 100 and taking corresponding adjustment measures, it can be ensured that the drill bit 111 always remains in a vertical state during the drilling process, thereby improving the drilling quality and efficiency.
[0032] It can be understood that when the casing 100 is detected to have a verticality deviation by the detection component, the controller controls the corresponding first adjustment unit 141 and the second adjustment unit 142 to operate according to the signal of the detection component, so as to achieve a more stable and flexible adjustment of the verticality of the casing 100. Even if some of the first adjustment units 141 and the second adjustment units 142 fail, the verticality of the casing 100 can still be adjusted by the remaining first adjustment units 141 and the second adjustment units 142.
[0033] Specifically, the detection component includes a first detection unit and a second detection unit; the first detection unit includes a plurality of laser displacement meters 1211 arranged along the circumference of the sleeve 100, and the second detection unit includes an arc needle roller row 131 arranged at the output end of the first adjustment unit 141, and a sensor located between the arc needle roller row 131 and the output end of the first adjustment unit 141, and the arc needle roller row 131 is abutted against the sleeve 100.
[0034] It can be understood that the laser displacement meter 1211 can monitor the operating status of the sleeve 100 in real time, and transmit data to the central processing unit through the first detection unit, so as to accurately control the displacement, speed, acceleration and other parameters of the sleeve 100; and the arc needle roller row 131 can provide real-time feedback on the contact status between the sleeve 100 and the needle roller row, and transmit the signal to the controller through the sensor.
[0035] Specifically, the remote-controlled full-casing and full-rotation drilling rig also includes a first driving device for driving the casing 100 to rotate, and a second driving device for driving the drill bit 111 to rotate; the output end of the first driving device is connected to a first transmission plate, and the end of the first transmission plate away from the first driving device is connected to a plurality of hydraulic cylinders that can be extended and retracted in the vertical direction, and the output end of the hydraulic cylinder is connected to the top end of the casing 100, and the plurality of hydraulic cylinders constitute a first adjusting unit 141; the output end of the second driving device is connected to the first driving assembly that can be extended and retracted in the vertical direction through the second transmission plate, and the output end of the first driving assembly is connected to the drill bit 111 through the drill rod 110.
[0036] It is understandable that the output end of the first driving device is connected to the first transmission plate, and the end of the first transmission plate away from the first driving device is connected to multiple hydraulic cylinders that can be extended and retracted in the vertical direction, and the output end of the hydraulic cylinder is connected to the top of the casing 100, which can make the casing 100 have better stability and flexibility in the vertical direction. When the casing 100 needs to be adjusted in verticality, the controller makes real-time adjustments through the first adjustment unit 141 and the second adjustment unit 142 according to the signal of the detection component. Even if some of the first adjustment units 141 and the second adjustment units 142 fail, the remaining units can continue to complete the adjustment of the verticality of the casing 100, ensuring the stable operation of the entire system.
[0037] Specifically, the remote-controlled full-casing and full-rotation drilling rig also includes a third driving device for driving the drill bit 111 and the casing 100 to rotate.

[0038] It can be understood that the output end of the third driving device is connected to the second driving assembly that can be retracted in the vertical direction through the third transmission plate, which can make the rotation of the drill bit 111 and the casing 100 more flexible and adapt to various complex geological conditions.
[0039] Specifically, the connecting member includes a plurality of rotary drill rods 150 arranged along the circumference of the drill rod 110 , and a fixed connecting member 160 is provided at one end of the rotary drill rod 150 away from the drill rod 110 , and a plurality of fixed protrusion blocks 101 cooperating with the fixed connecting member 160 are provided at the top end of the casing 100 .

[0041] Specifically, the remote-controlled full-casing and full-rotation drilling rig further includes a main frame 200 , a bottom plate 201 of the main frame 200 is provided with a casing hole 210 for cooperating with the casing 100 , and the main frame 200 is a cubic frame.

[0044] Specifically, the other end of the slurry discharge pipe 221 is connected to the mud separator 250 , one end of the air intake pipe 230 is provided with a plurality of radially distributed air intake branches 231 , and one end of the slurry discharge pipe 221 is provided with a plurality of radially distributed slurry discharge branches 2211 .
[0045] It can be seen that the mud separator 250 can effectively separate and process the mud, further improving the efficiency and environmental performance of the drilling operation; the air intake branch pipe 231 and the slurry discharge branch pipe 2211 are radially distributed, which helps to achieve comprehensive stirring and uniform discharge of the mud, and reduce the risk of mud coagulation and blockage.
