[0029] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] As Figures 1-3As shown in the figure, a quick connection device includes a male connector 101 and a female connector 107. The male connector 101 and the female connector 107 can be respectively installed at both ends of a drill pipe. One end of the male connector 101 is provided with a connecting rod 106, and the female connector 107 is provided with a connecting groove 111 corresponding to the connecting rod 106; a plurality of first hook parts are provided on the side wall of the male connector 101, and a plurality of second hook parts are provided on the side wall of the female connector 107. The number of the second hook parts is the same as that of the first hook parts; the first hook part includes a connecting ring 102, a first vertical section 103, a first horizontal section 104 and a second vertical section 105. The first vertical section 103 and the second vertical section 105 are respectively arranged at both ends of the first horizontal section 104, and the first vertical section 103 is used for connecting the connecting ring 102 and the first horizontal section 104; the second hook part is arranged at the top of the side wall of the connecting groove 111. The second hook part includes a third vertical section 108, a second horizontal section 109 and a fourth vertical section 110. The third vertical section 108 and the fourth vertical section 110 are respectively arranged at both ends of the second horizontal section 109, and the third vertical section 108 is used for connecting the female connector 107 and the second horizontal section 109.

[0031] The distance between adjacent first hook parts is greater than the width of the second hook part, and the distance between adjacent second hook parts is greater than the width of the first hook part; the distance between the first horizontal section 104 and the connecting ring 102 is greater than the sum of the length of the fourth vertical section 110 and the width of the second horizontal section 109, and the distance between the second horizontal section 109 and the top surface of the connecting groove 111 is greater than the sum of the length of the second vertical section 105 and the width of the first horizontal section 104; the distance between the first vertical section 103 and the second vertical section 105 corresponds to the width of the fourth vertical section 110, and the distance between the third vertical section 108 and the fourth vertical section 110 corresponds to the width of the second vertical section 105.

[0032] Preferably, three first hook parts are provided, and three second hook parts are also provided. The three first hook parts are arranged on the male connector 101 at an interval of 120°, and the three second hook parts are arranged on the female connector 107 at an interval of 120°.

[0033] When connecting two drill pipes, the male connector 101 on one drill pipe is connected to the female connector 107 on the other drill pipe. The connecting rod 106 on the male connector 101 is inserted into the connecting groove 111 on the female connector 107. The first hook part is inserted between two adjacent second hook parts, and the second hook part is inserted between two adjacent first hook parts. Then one of the drill pipes rotates relative to the other drill pipe. The second vertical section 105 moves to the position of the third vertical section 108. The drill pipe at the upper end is lifted. The second vertical section 105 is embedded in the groove between the third vertical section 108 and the fourth vertical section 110, and the fourth vertical section 110 is embedded in the groove between the first vertical section 103 and the second vertical section 105, completing the connection of the two drill pipes.

[0034] Since the first motor drives the drill pipe to rotate in the same direction during the drilling operation, the second vertical section 105 will always abut against the third vertical section 108, and the first vertical section 103 will always abut against the fourth vertical section 110. Therefore, the male connector 101 and the female connector 107 can achieve a stable connection effect during the drilling operation and will not become detached, improving the safety of the operation. At the same time, with the setting of the quick connection device, the connection of the two drill pipes can be quickly formed, simplifying the drill pipe connection process. There is no need to precisely align the two drill pipes in a cumbersome manner, improving the drilling operation efficiency.

[0035] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above utility model concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in the embodiments of the present disclosure.
