[0029] refer to Figure 1-Figure 3 and Figure 6As shown, the positioning module 2 also includes an assembly plate 219, a secondary pressure sensor 220, a secondary frame plate 221 and a secondary scroll wheel 222.

The secondary frame plate 221 is arranged on the left side of the assembly plate 219. The secondary pressure sensor 220 is connected between the secondary frame plate 221 and the assembly plate 219. The secondary scroll wheel 222 is arranged in the secondary frame plate 221, and the front and rear ends of the secondary scroll wheel 222 are rotatably connected to the secondary frame plate 221 through a rotating shaft. When the secondary scroll wheel 222 is separated from the upper drill rod, the squeezing force between the secondary scroll wheel 222 and the upper drill rod is lost, and the value monitored by the secondary pressure sensor 220 becomes smaller. The secondary pressure sensor 220 transmits the data to the external terminal, and the external terminal receives the data and controls the secondary drive motor 217 to turn off.

[0030] The secondary scroll wheel 222 is located directly below the primary scroll wheel 25 on the right side.

[0031] refer to Figures 1-6 As shown, the air supply module 3 also includes a hollow ring 32, an air pump 33, a conduit 34, a telescopic hose 35 and a screen 36. The hollow ring 32 is connected to the bottom of the base ring 1, and the air pump 33 is connected to the bottom of the extension plate 27 on the right side through a positioning bolt. The conduit 34 is connected between the hollow ring 32 and the air pump 33, and the telescopic hose 35 is connected between the hollow ring 32 and the arc-shaped guide plate 26, and the end of the telescopic hose 35 away from the hollow ring 32 is connected to the air supply port 31, and the screen 36 is arranged in the air supply port 31, and the screen 36 is connected to the arc-shaped guide plate 26. The air pump 33 blows air through the conduit 34, the hollow ring 32, the telescopic hose 35, and the air supply port 31 to the connecting head of the lower drill pipe in turn, and blows away the debris, particulate matter and other impurities on the outer wall of the connecting head by wind force, and the setting of the screen 36 can prevent impurities such as debris and particulate matter from entering the air supply port 31.

[0032] Working principle: The base ring 1 is placed on the outside of the upper drill rod, and the first-level driving motor 28 is started. The output end of the first-level driving motor 28 drives the gear 29 to rotate, and the gear 29 drives the gear ring 21 to rotate. The track plate 210 rotates with the gear ring 21, so that the round rod 212 slides in the track groove 211, thereby driving the push plate 22 and the first-level rolling wheel 25 to move toward the upper drill rod until the first-level rolling wheel 25 contacts the upper drill rod. The squeezing force applied to the upper drill rod by the first-level rolling wheel 25 on the right side is monitored by the first-level pressure sensor 231, and the setting of the connecting block 232 makes the shape and specifications of the connecting block 232 consistent with the first-level pressure sensor 231, which can not only ensure that multiple groups of one The secondary scroll wheel 25 is in contact with the outer wall of the upper drill rod at the same time, and can also ensure the monitoring effect of the first-level pressure sensor 231 on the squeezing force applied to the upper drill rod by the first-level scroll wheel 25 on the right. When the squeezing force reaches a preset value, the first-level pressure sensor 231 transmits the data to the peripheral terminal, and the peripheral terminal receives the data and controls the first-level drive motor 28 to turn off and the second-level drive motor 217 to turn on. The output shaft of the second-level drive motor 217 drives the first-level scroll wheel 25 on the left to rotate, and cooperates with the other first-level scroll wheels 25 to make the device descend on the outer wall of the upper drill rod. Since the second-level scroll wheel 222 is directly below the first-level scroll wheel 25 on the right, the second-level scroll wheel 222 and the first-level scroll wheel 25 on the right are in contact with each other. , the pushing plate 22 on the right side moves synchronously. When the secondary scroll wheel 222 contacts the outer wall of the upper drill rod, the values ​​monitored by the secondary pressure sensor 220 and the primary pressure sensor 231 are consistent. As the device descends, when the secondary scroll wheel 222 separates from the upper drill rod, the squeezing force between the secondary scroll wheel 222 and the upper drill rod is lost, and the value monitored by the secondary pressure sensor 220 becomes smaller. The secondary pressure sensor 220 transmits the data to the external terminal. The external terminal receives the data and controls the secondary drive motor 217 to turn off and the air pump 33 to turn on. Since the arc-shaped guide plate 26 is connected to the primary frame plate 24 through the vertical plate 218, and the arc-shaped guide plate 26 corresponds to the primary scroll wheel 25 one by one, at the primary scroll After the wheel 25 is pressed against the outer wall of the upper drill rod, the multiple arc-shaped guide plates 26 approach each other and form a funnel-like structure. When the upper drill rod descends and gradually approaches the lower drill rod, the arc-shaped guide plates 26 can better guide the connector at the top of the lower drill rod to the bottom of the upper drill rod, thereby assisting personnel in inserting the connector into the screw hole. When the arc-shaped guide plates 26 approach the connector at the top of the lower drill rod, the air pump 33 blows air to the connector of the lower drill rod through the guide tube 34, the hollow ring 32, the telescopic hose 35, and the air supply port 31 in sequence, blowing away debris, particles and other impurities on the outer wall of the connector through the wind, preventing impurities from being trapped between the connector and the screw hole and reducing the connection effect between the upper drill rod and the lower drill rod, thereby improving the connection strength;

[0033] When the secondary scroll wheel 222 is separated from the upper drill rod, the squeezing force applied by the primary scroll wheel 25 on the right side to the upper drill rod can be monitored at all times through the primary pressure sensor 231. When the squeezing force is lower than the preset value, the primary pressure sensor 231 transmits the data to the peripheral terminal. The peripheral terminal receives the data and controls the primary drive motor 28 to turn on, so that the primary scroll wheel 25 moves toward the upper drill rod, thereby strengthening the pressing effect of the primary scroll wheel 25 on the upper drill rod.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
