[0046] The present invention also provides a method for using an intelligent drilling device for gas extraction construction, which includes the following specific steps:

[0047] Step 1: The main drill rod can be driven by the driving mechanism to perform preliminary drilling work. When the drill rod needs to be extended, the first motor can be started by the controller. The first motor drives the rotating rod to rotate, and the first conveying ring and the second conveying ring on the conveyor belt are driven by the conveyor wheel to rotate synchronously, so that one of the multiple auxiliary drill rods can be rotated to the top of the main drill rod;

[0048] Step 2: The cylinder is activated by the controller. The cylinder can drive the fixed frame to move while driving the extrusion ring to descend. When the clamping block is engaged with the clamping groove provided on the auxiliary drill rod, the cylinder can squeeze the synchronization ring, so that the synchronization ring drives the multiple extrusion rods to descend, thereby causing the multiple extrusion blocks to squeeze the chute, so that the multiple clamping rods are away from the auxiliary drill rod. At this time, the auxiliary drill rod is no longer fixed, and the second motor can be started to rotate and install the auxiliary drill rod.

[0049] Step 3: When the clamping rod releases the clamping fixation on the auxiliary drill rod, the fixing rod is inserted into the groove opened by the second conveying ring. The magnet plate will be attracted by the iron sheet and stuck into the positioning groove. As a result, the synchronous ring is squeezed by the squeezing ring and is clamped with the positioning groove by the magnet plate to limit the position. It will not rebound and reset. At this time, the multiple clamping rods remain in the open state, and the new auxiliary drill rod can be loaded.

[0050] Step 4: After the new auxiliary drill rod is placed inside the first conveying ring and the second conveying ring and rotated to the side of the inner wall of the machine body, the electromagnet block can be briefly energized. During the energization period, the electromagnet block will generate a large magnetic force, thereby adsorbing the magnet plate, and the suction force is much greater than the suction force between the magnet plate and the iron sheet. At this time, the magnet plate will break away from the positioning groove and shrink to the inside of the slide groove. At this time, under the elastic force of multiple second compression springs, the synchronization ring will bounce back and reset, and the clamping rod will also clamp and fix the auxiliary drill rod under the force of multiple extrusion rods and the extrusion block for next use.

[0051] Technical effects and advantages of the present invention:

[0052] The present invention utilizes a setting mode that cooperates with a conveying mechanism, an auxiliary drill rod, an installation mechanism and a fixing mechanism. The fixing mechanism can be used to fix multiple auxiliary drill rods on the conveying mechanism. After each drill rod is used, the next drill rod can be promptly conveyed to the top of the previous drill rod through the conveying mechanism through the conveying mechanism. The installation mechanism can release the fixing mechanism of the auxiliary drill rod and at the same time install and connect the auxiliary drill rod with the previous drill rod, which greatly reduces the demand for human resources and the time of drilling connection, and improves the efficiency of drilling.

Even if the clamping block 663 cannot be clamped with the clamping groove at the beginning, it will be clamped with the clamping groove under the elastic force of the first compression spring 664 during the slow start-up of the second motor 64.

[0066] Specifically, the fixing mechanism 7 comprises clamping rods 71, extrusion rods 72, extrusion blocks 73, a synchronous ring 74, second compression springs 75 and a positioning assembly 76. The inner wall of the first conveying ring 45 is equidistantly provided with a plurality of clamping grooves. The clamping rods 71 are slidably connected with the inner cavities of the clamping grooves. The clamping rods 71 are fixedly connected with rubber pads at one end in the inner cavity of the first conveying ring 45. The rubber pads are provided with anti-skid textures, so as to centerally clamp the secondary drill rod 5. Meanwhile, the inner wall of the second conveying ring 46 can assist in limiting the secondary drill rod 5, so that the clamping rods 71 can fix the secondary drill rod 5 in a vertical state.

After the new secondary drill rod 5 is placed in the first conveying ring 45 and the second conveying ring 46, the electromagnet block 765 can be energized. At this time, the electromagnet block 765 will generate a large magnetic force, thereby adsorbing the magnet plate 762. The adsorption force is much larger than the adsorption force between the magnet plate 762 and the iron sheet 763. At this time, the magnet plate 762 will be separated from the positioning groove and shrink into the inner part of the sliding groove. At this time, under the elastic force of the plurality of second compression springs 75, the synchronous ring 74 will be re-erected and reset. The clamping rod 71 will clamp and fix the secondary drill rod 5 under the force of the plurality of pressing rods 72 and the pressing block 73, for next use.

10. A method for using an intelligent drilling device for gas extraction construction according to any one of claims 1 to 9, characterized in that: The specific steps are as follows: Step 1: The main drill rod (10) can be driven by the driving mechanism (2) to perform preliminary drilling work. When the drill rod needs to be extended, the first motor (41) can be started by the controller (9). The first motor (41) drives the rotating rod (42) to rotate, and the first conveying ring (45) and the second conveying ring (46) on the conveyor belt (44) are driven by the conveying wheel (43) to rotate synchronously, so that one of the multiple auxiliary drill rods (5) can be rotated to the top of the main drill rod (10); Step 2: The cylinder (62) is started by the controller (9). The cylinder (62) can drive the fixed frame (63) to move while driving the extrusion ring (65) to descend. When the clamping block (663) is clamped with the clamping groove provided by the auxiliary drill rod (5), the cylinder (62) can squeeze the synchronization ring (74), so that the synchronization ring (74) drives the multiple extrusion rods (72) to descend, thereby causing the multiple extrusion blocks (73) to squeeze the inclined groove, so that the multiple clamping rods (71) are away from the auxiliary drill rod (5). At this time, the auxiliary drill rod (5) is no longer fixed, and the second motor (64) can be started to rotate and install the auxiliary drill rod (5); Step 3: When the clamping rod (71) releases the clamping fixation on the auxiliary drill rod (5), the fixing rod (761) is inserted into the groove opened by the second conveying ring (46), and the magnet plate (762) is adsorbed with the iron sheet (763) and is stuck into the interior of the positioning groove, so that the synchronous ring (74) is squeezed by the squeezing ring (65) and is clamped with the positioning groove by the magnet plate (762) to limit the position, and will not rebound and reset. At this time, the multiple clamping rods (71) remain in the open state, and a new auxiliary drill rod (5) can be loaded; Step 4: After the new auxiliary drill rod (5) is placed inside the first conveying ring (45) and the second conveying ring (46) and rotated to the side of the inner wall of the body (3), the electromagnet block (765) can be briefly energized. During the energization period, the electromagnet block (765) will generate a large magnetic force, thereby adsorbing the magnet plate (762), and the suction force is much greater than the suction force between the magnet plate (762) and the iron sheet (763). At this time, the magnet plate (762) will be separated from the positioning groove and retracted to the inside of the slide groove. At this time, under the elastic force of the multiple second compression springs (75), the synchronization ring (74) will rebound and reset, and the clamping rod (71) will also clamp and fix the auxiliary drill rod (5) under the force of the multiple extrusion rods (72) and the extrusion block (73) for next use.
