[0029] The specific contents of the present invention are further explained in detail below with reference to the embodiments. DETAILED DESCRIPTION

[0030] Specific embodiments of the present invention are given below. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent modifications made on the basis of the technical solution of this application fall within the protection scope of the present invention.

[0031] Directional terms mentioned in this document, such as "transverse", "radial", "horizontal" and "vertical" are consistent with the specific directions on the paper of the drawings in the specification or the corresponding directions in the space shown in the drawings.

[0032] Example 1:

[0033] A drill rod unclip device includes a first swing arm 1, a second swing arm 2, a first movable joint 3 and a first power mechanism 4. One side of the second swing arm 2 is connected to the first swing arm 1 through the first movable joint 3. The first movable joint 3 is slidably arranged on the first swing arm 1. The second swing arm 2 is provided with a first mounting groove 5 on the side away from the first movable joint 3. The drill rod 01 can be clamped in the first mounting groove 5. The first swing arm 1 is provided on the side away from the first movable joint 3 on the frame 01. The first power mechanism 4 is provided on the first swing arm 1. The two ends of the first power mechanism 4 are respectively connected to the first movable joint 3 and the frame 01.

[0034] The drill rod detaching device of the present invention connects one side of the second swing arm 2 to the first swing arm 1 through the first movable joint 3, so that the second swing arm 2 can rotate on the first swing arm around the first movable joint 3. When the device of the present invention is used, the rotation of the second swing arm 2 can adjust the angle between the second swing arm 2 and the first swing arm 1 so that the drill rod can be clamped on the first mounting groove provided on one side of the second swing arm 2, and the drill rod is fixed through the first mounting groove. One side of the first swing arm is also provided on the frame 01 to provide a fulcrum for the device of the present invention. A pulling force is applied to the first movable joint 3 through the first power mechanism 4. The first movable joint 3 slides on the first swing arm 1 under the action of the pulling force, thereby driving the second swing arm 2 to slide on the first swing arm 1. The second swing arm 2 drives the drill rod provided in the first mounting groove to be subjected to tension, so that the thread of the drill rod is detached.

[0035] Among them, the first power mechanism in this embodiment is a single-rod double-acting articulated cylinder, the first movable joint is a rotating shaft, the cylinder extends the second swing arm 2 away from the first swing arm and rotates, after the drill rod is fixed, the cylinder contracts to provide pulling force.

The second mounting groove 6 is arranged on the second swing arm 2 close to the side of the first mounting groove 5. The second mounting groove 6 can be matched with the first mounting groove 5. The two ends of the second power mechanism 8 are respectively connected to the first movable joint 3 and the second movable joint 7.

[0037] Among them, the second mounting groove is set to cooperate with the first mounting groove to realize the fixation of the drill rod, which makes the fixation of the drill rod more secure and stable. When the second mounting groove cooperates with the first mounting groove to clamp the drill rod, they both match the outer periphery of the drill rod. By setting the fourth movable joint 15, the rotation of the first mounting groove 5 and the second mounting groove 6 is adjusted to facilitate matching with the drill rod. The second power mechanism 8 is a single-rod double-acting articulated cylinder used to control the rotation of the second movable joint 7. Specifically, in this embodiment, when the device needs to match the target disassembled drill rod, the second power mechanism 8 is extended, and the second movable joint 7 is pushed to increase the angle between the second mounting groove and the first swing arm 1. This state is referred to as the second swing arm opening in this article, which surrounds the drill rod. Then, the second power mechanism 8 contracts, and the second movable joint 7 is pulled to reduce the angle between the second mounting groove and the first swing arm 1. This state is referred to as the second swing arm clamping in this article. At this time, the second mounting groove cooperates with the first mounting groove to clamp the drill rod 01.

[0055] The working process of the present invention:

[0056] 1) The power head drives the drill pipe to lift the drill until the thread is between the clamp 03 and the drill pipe breaker device 06 and stops moving. At this time, the power head 04 and the feed cylinder are in a floating state;

[0057] 2) The cylinder rod of the second power mechanism of the drill pipe breakout device 06 extends, and the second swing arm opens. The pressure sensor of the oil circuit of the second power mechanism cylinder detects whether the cylinder rod is fully extended. When the pressure of the pressure sensor increases significantly, it proves that the second power mechanism has been fully opened;

[0058] 3) The cylinder rod of the third power mechanism extends, and the drill rod breaker device 06 as a whole moves toward the second drill rod. Driven by the first power mechanism, the second swing arm rotates clockwise to the center of the drill rod. When the pressure sensor pressure of the third power mechanism increases instantly, it proves that the cylinder rod has been fully extended. At this time, the center of the first mounting groove on the second swing arm is concentric with the center of the drill rod;

[0059] 4) The fourth power mechanism oil cylinder extends, and the second swing arm is adjusted according to the thread positions of the first drill rod and the second drill rod, so that the second swing arm is located between the second drill rod and the power head. In this embodiment, the second swing arm is located 20 cm from the thread.

[0060] 5) The second power mechanism oil cylinder rod retracts and the second swing arm is clamped. When the oil pressure in the clamping oil cylinder increases instantaneously, it proves that the first swing arm and the second swing arm have clamped the second drill pipe;

[0061] 6) The first power mechanism oil cylinder rod retracts, driving the first movable joint to move along the arc from A to B, and the fourth movable joint to move along the arc from C to D. At this time, the second swing arm shackles counterclockwise. When the displacement sensor detects that the mounting frame has a displacement change and the pressure sensor pressure of the first power mechanism oil cylinder oil circuit instantly drops below 2MPa, the first and second drill rods have been loosened;

[0062] 7) The second power mechanism cylinder rod extends, the second swing arm opens and releases the second drill rod, the first power mechanism cylinder rod extends, and the fourth power mechanism cylinder rod retracts, driving the first swing arm counterclockwise back to its original position, completing a shackle;

[0063] 8) By repeating the program, the drill pipe can be continuously broken out.
