[0027] refer to Figure 1-Figure 6 As shown, the air supply module 3 also includes a hollow ring 32, an air pump 33, a duct 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 duct 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.

[0028] Working principle: The base ring 1 is sleeved on the outer side 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 extrusion 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 specification of the connecting block 232 consistent with the first-level pressure sensor 231, which can not only ensure that multiple groups of one The first-level 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 extrusion force applied to the upper drill rod by the first-level scroll wheel 25 on the right side. When the extrusion force reaches a preset value, the first-level pressure sensor 231 transmits data to the external terminal, and the external 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 side 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 side, the second-level scroll wheel 222 and the first-level scroll wheel 25 on the right side are in contact with each other. , the pushing plate 22 on the right side moves synchronously. When the secondary rolling 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 rolling wheel 222 separates from the upper drill rod, the squeezing force between the secondary rolling 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 rolling wheel 25 one by one, at the primary rolling After the wheel 25 is pressed against the outer wall of the upper drill rod, the multiple arc-shaped guide plates 26 are close to 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, so as to assist the personnel to insert the connector into the screw hole. When the arc-shaped guide plate 26 approaches 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 conduit 34, the hollow ring 32, the telescopic hose 35, and the air supply port 31 in sequence, and blows away impurities such as debris and particles on the outer wall of the connector by wind, so as to prevent impurities from being between the connector and the screw hole, thereby reducing the connection effect between the upper drill rod and the lower drill rod, thereby improving the connection strength; 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 external terminal. The external terminal receives the data and controls the primary drive motor 28 to start, 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.
