Description

Technical Field

[0001] This utility model relates to the field of exploration drilling rig connection, and in particular to an anti-detachment connection device for exploration drilling rig drill rod. Background Technology

[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It is a survey and research activity that discovers industrially significant mineral deposits during mineral prospecting, provides mineral reserves and geological data needed for mine construction design to ascertain the quality and quantity of minerals and the technical conditions for mining and utilization, and investigates and studies the geological conditions such as rocks, strata, structures, minerals, hydrology, and geomorphology in a certain area.

[0003] In geological exploration and mineral resource development projects, exploration drilling rigs are one of the core pieces of equipment. The stable connection of the drill rods directly affects exploration efficiency and operational safety. Currently, the connection between drill rods mostly adopts the traditional threaded connection method. Under the long-term high-frequency vibration, axial load, and complex geological environment, this method is prone to thread loosening. When the threads loosen to a certain extent, the drill rod may come off, which will not only lead to the interruption of exploration operations and equipment damage, but may also cause safety accidents and threaten the personal safety of operators. To address this issue, we propose an anti-detachment connection device for exploration drilling rig drill rods to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a drill rod anti-detachment connection device for exploration drilling rigs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A drill rod anti-detachment connection device for an exploration drilling rig includes a male connector and a female connector. The outer surface of the male connector is provided with an external thread, and the inner surface of the female connector is provided with an internal thread. The external thread and the internal thread are adapted to each other. A fixing sleeve is threadedly connected to the outer surface of the male connector and the outer surface of the female connector. One end of the male connector is connected to a guide post, and a fixing component is connected to the outer surface of the female connector.

[0006] In a further embodiment, the female connector has an annular groove inside, and a sealing gasket is connected inside the annular groove.

[0007] In a further embodiment, the fixing component includes a fixing block connected to the outer surface of the female connector. A spring is connected to the outer surface of the fixing block, a pressing plate is connected to the top of the spring, a locking rod is connected to the outer surface of the pressing plate, and a locking groove is formed on the outer surface of the guide post, with the locking rod matching the locking groove.

[0008] In a further embodiment, both the outer surface of the fixing block and the outer surface of the pressing plate are provided with threaded holes, and the inner walls of the two threaded holes are connected by a fastening bolt.

[0009] In a further embodiment, the sealing gasket is made of nitrile rubber, and the outer surface of the fixing sleeve is provided with anti-slip ridges.

[0010] In a further embodiment, both the male connector and the female connector are made of alloy steel, and the outer surfaces of both the male connector and the female connector are coated with an anti-rust layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device achieves initial connection through the external thread of the male connector and the internal thread of the female connector, and then further secures the two with the help of the fixing sleeve. At the same time, the fixing components form a multi-layer anti-loosening structure, which effectively solves the problem of easy loosening and separation of traditional threaded connections, and significantly improves the stability and safety of drill rod connection. The fastening bolts and threaded holes in the fixing components can effectively fix the pressing plate and the fixing block, preventing the clamp rod from falling off due to vibration, thus providing double protection for the anti-loosening effect of the fixing components.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 In this utility model, an anti-detachment connection device for drill rod of exploration drilling rig includes a male connector 1 and a female connector 2. The outer surface of the male connector 1 is provided with an external thread 3, and the inner surface of the female connector 2 is provided with an internal thread 4. The external thread 3 and the internal thread 4 are adapted to each other. The outer surface of the male connector 1 and the outer surface of the female connector 2 are threadedly connected to a fixing sleeve 5. One end of the male connector 1 is connected to a guide post 6, and the outer surface of the female connector 2 is connected to a fixing component 9.

[0021] The female connector 2 has an annular groove 7 inside, and a sealing gasket 8 is connected inside the annular groove 7. The cooperation of the annular groove 7 and the sealing gasket 8 can effectively prevent external mud, water, etc. from entering the connection gap, avoiding corrosion of threaded parts. The sealing gasket 8 is made of nitrile rubber. The outer surface of the fixing sleeve 5 has anti-slip ridges. The anti-slip ridge design can increase the friction between the operator's hand and the fixing sleeve 5, making it easier to apply force when installing and removing the fixing sleeve 5. The nitrile rubber sealing gasket 8 has excellent sealing performance and aging resistance. Both the male connector 1 and the female connector 2 are made of alloy steel. The outer surfaces of both the male connector 1 and the female connector 2 are coated with an anti-rust layer. The alloy steel male connector 1 and the female connector 2 have high strength, high toughness and good wear resistance, and can withstand high-frequency vibration and large loads in exploration operations, ensuring the structural strength of the connection device. The anti-rust layer can effectively isolate corrosive media such as air and moisture, slow down the corrosion rate of the device and extend its service life.

[0022] The fixing component 9 includes a fixing block 901, which is connected to the outer surface of the female connector 2. A spring 902 is connected to the outer surface of the fixing block 901, and a pressing plate 903 is connected to the top of the spring 902. A locking rod 904 is connected to the outer surface of the pressing plate 903. A locking groove 905 is formed on the outer surface of the guide post 6, and the locking rod 904 is adapted to the locking groove 905. Threaded holes 906 are formed on the outer surfaces of both the fixing block 901 and the pressing plate 903. The inner wall of the threaded hole 906 is connected to a fastening bolt 907. After the male connector 1 and the female connector 2 are connected in place, the pressing plate 903 is pressed to compress the spring 902, thereby causing the locking rod 904 to be locked into the locking groove 905, realizing the axial limit of the male connector 1 and the female connector 2, preventing them from separating under axial load. Then, the fastening bolt 907 is rotated to make the fastening bolt 907 rotate inside the threaded hole 906, thereby fixing the pressing plate 903.

[0023] The working principle of this utility model is as follows: In use, first align the guide post 6 of the male connector 1 with the inlet of the female connector 2. Through the engagement of the external thread 3 and the internal thread 4, screw the male connector 1 into the female connector 2 until it is in place, so that the end of the male connector 1 presses against the sealing gasket 8 to achieve a seal. Then rotate the fixing sleeve 5 to reinforce the connection between the two. Then press the pressing plate 903 to compress the spring 902, so that the locking rod 904 is engaged with the inside of the locking groove 905. Then rotate the fastening bolt 907 to rotate the fastening bolt 907 inside the threaded hole 906, thereby fixing the pressing plate 903.
