At this time, the metal spring is embedded in the bayonet and the limiting protrusion is correspondingly buckled into the limiting port.

[0004] The connection between the two drill rods is a stress concentration site. During the drilling process, the drill rods have to withstand huge axial pressure, torque and vibration. However, in this device, there are no components for reinforcing the drill rod connection. Therefore, under the action of these pressures, the connection between the two drill rods is prone to breakage. Utility Model Content

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-6As shown, a hydraulic ring geological drilling aluminum alloy drill rod includes a geological drill rod 1, a docking rod 6 and a docking port 7. A small pipe section 2 is provided at one end of the geological drill rod 1, and the docking port 7 is provided on the end face of the small pipe section 2. A receiving groove 9 is provided at the other end of the small pipe section 2 and the geological drill rod 1. A reinforcement rod 8 is hinged in the receiving groove 9 at the other end of the geological drill rod 1. The edge of one end of the geological drill rod 1 extends outward to form an extension 3. The extension 3 is internally threaded with a fixing ring 4 for limiting the reinforcement rod 8. An intermediate groove 14 is provided on the small pipe section 2, and an external clamping block 13 is slidably installed in the intermediate groove 14. An external clamping hole 15 for clamping the external clamping block 13 is provided on the fixing ring 4. An internal clamping block 12 that is plugged into the intermediate groove 14 is provided on the docking rod 6.

[0025] In this technical solution, by setting the small tube section 2, the outer wall of the small tube section 2 and the extended edge 3 are gap-matched, and the fixing ring 4 is installed in the gap between the outer wall of the small tube section 2 and the extended edge 3.

[0026] By setting the accommodating groove 9, when connecting two geological drill rods 1, the reinforcement rod 8 inside is swung, and one end moves out of the accommodating groove 9. At this time, the docking rod 6 can be inserted into the docking port 7 and relatively rotated and threadedly installed. When reinforcing the connection between the two geological drill rods 1, the reinforcement rod 8 is swung into the accommodating groove 9. By setting the external clamping hole 15 and the external clamping block 13, the fixing ring 4 moves upward through the thread, and the inner side wall of the fixing ring 4 squeezes the reinforcement rod 8. After the reinforcement rod 8 is fixed, the external clamping block 13 moves outward and is inserted into the external clamping hole 15, so that the fixing ring 4 and the small pipe section 2 are relatively fixed.

[0027] The material of the reinforcement plate 8 can be high-strength alloy steel.

[0028] like Figure 5 As shown, an inner slot 11 is provided on the docking rod 6 , a spring rod 10 is fixedly installed in the inner slot 11 , the telescopic end of the spring rod 10 is fixedly connected to the inner block 12 , and the inner block 12 is slidably installed with the inner slot 11 .

[0029] In the present technical solution, by setting the inner clamping block 12, when installing the docking rod 6 and the docking port 7, the inner wall of the docking port 7 will squeeze the inner clamping block 12 into the inner clamping groove 11 and shrink the spring rod 10. After the docking rod 6 and the docking port 7 are installed, the middle groove 14 is exactly opposite to the inner clamping groove 11, and the spring rod 10 stretches, pushing the inner clamping block 12 into the middle groove 14. The two connected geological drill rods 1 are clamped by the inner clamping block 12, so that they are not easy to fall off.

[0030] like Figure 4 As shown, the middle portion of the outer clamping block 13 is concave, and a convex ring 16 is fixedly connected to the inner side of the middle groove 14 and is slidably matched with the concave portion of the outer clamping block 13 .

[0031] In this technical solution, by providing a convex ring 16, the middle groove 14 is in the shape of a through hole, passing through the side wall of the small tube section 2, and the convex ring 16 is used to control the outer clamping block 13 from falling out of the middle groove 14, and when the spring rod 10 pushes the inner clamping block 12 into the middle groove 14, the inner clamping block 12 abuts against the outer clamping block 13, and the movement of the inner clamping block 12 drives the outer clamping block 13 to move outward.

[0032] like Figure 3 As shown, the docking rod 6 and the docking port 7 are installed through threads, and the threads between the docking rod 6 and the docking port 7 are arranged in the same spiral direction as the threads between the extension 3 and the fixing ring 4.

[0033] like Figure 3 As shown, a plurality of reinforcement rods 8 are provided and the plurality of reinforcement rods 8 are arranged opposite to each other.

[0034] In this technical solution, multiple reinforcement rods 8 are provided throughout to enhance the fixing effect.

[0035] like Figure 1 As shown, the outer card hole 15 end is provided with a reinforcement ring 5.

[0036] Working principle: When connecting two geological drill rods 1, first screw the docking rod 6 of one geological drill rod 1 into the docking port 7 of the other geological drill rod 1. The inner wall of the docking port 7 squeezes the inner card block 12 into the inner card groove 11, and contracts the spring rod 10. When the docking rod 6 and the docking port 7 are about to be installed, the reinforcement rod 8 swings into the two receiving grooves 9 that are about to be combined together. After that, slightly rotate the docking rod 6 to complete the installation of the docking rod 6 and the docking port 7. At this time, the middle groove 1 4 is exactly opposite to the inner card slot 11, the spring rod 10 is extended, and the inner card block 12 is pushed into the middle groove 14, so that the docking rod 6 and the docking port 7 are fixed to each other and cannot rotate, and the outer card block 13 is pushed outward. The rotating fixing ring 4 moves upward through the thread, and the inner side wall of the fixing ring 4 squeezes the reinforcement rod 8. After the reinforcement rod 8 is fixed, the outer card hole 15 is exactly opposite to the middle groove 14, and the outer card block 13 moves outward and passes into the outer card hole 15, so that the fixing ring 4 cannot rotate relative to the extension 3.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
