[0017] 3. Beneficial effects

[0018] (1) A reinforcement component is provided on the top of the hexagonal block of the present invention. The slider on the surface of the guide rod moves in a direction away from the triangular block under the influence of the rotating centrifugal force. The plug block originally inserted into the square groove is inserted deeper, and the centrifugal force is used to increase the connection firmness.

The above structure solves the problem that the original joint is connected by surfacing and welding, and it is difficult to replace after wear.

[0019] (2) In the present invention, a speed component is provided on the top of the reinforcement component. The faster the speed of the drill rod, the farther the distance between the slider and the triangular block. When the cylinder moves upward and the telescopic rod is fully retracted, the telescopic rod pushes the first cylindrical block upward, and the retracted distance of the telescopic rod is used as a buffer. The retracted distance of the telescopic rod is also used to distinguish the speed of the rotation. The above structure solves the problem of being unable to judge the drilling speed.

[0020] (3) In the present invention, a wave assembly is provided on the top of the speed assembly. By utilizing the reflux of hydraulic oil, the hydraulic push rod contracts and drives the closing plate to move upward, so that the drill rod moves upward. The drill rod brings out the gravel produced by drilling, thereby reducing the friction force on the drill rod during rotation. The above structure solves the problem of increased friction force caused by gravel produced by drilling, which leads to slower drilling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Embodiment 1:

[0032] See also Figure 1-4 A connecting plug for a drilling rig of a drilling rig ship, comprising a drill rod 1, a square groove 2 is formed on the drill rod 1, a hexagonal groove is formed on the inner wall of the drill rod 1, and a hexagonal block 3 is inserted in the inner wall of the drill rod 1 and located at the hexagonal groove;

[0033] A reinforcement component 4 is provided on the top of the hexagonal block 3. The reinforcement component 4 uses centrifugal force to fix the position of the hexagonal block 3 and uses the magnitude of the centrifugal force to judge the working state of the drill pipe 1, so as to strengthen the connection during operation and facilitate maintenance when the operation stops.

[0034] A speed component 5 is provided on the top of the reinforcement component 4, and the speed component 5 uses the centrifugal force to determine the drilling speed of the drill rod 1;

[0035] A fluctuation component 6 is provided on the top of the rotation speed component 5. The fluctuation component 6 adjusts the height of the drill rod 1 according to the drilling speed, and fluctuates the drill rod 1 up and down to remove the gravel generated by the drilling, thereby speeding up the drilling efficiency.

[0036] The reinforcement component 4 , the rotation speed component 5 and the wave component 6 form a connecting plug-in, and a sleeve 7 is arranged on the top of the wave component 6 .

[0037] The reinforcement component 4 includes a first circular tube 401, a bottom plate 412 is fixedly installed at the bottom of the first circular tube 401, the bottom of the bottom plate 412 is fixedly connected to the hexagonal block 3, a triangular block 402 is fixedly installed at the top center of the bottom plate 412, a guide rod 403 is fixedly installed on the side of the triangular block 402, a slider 404 is slidably connected to the surface of the guide rod 403, an insert block 405 is fixedly installed on the side of the slider 404 close to the first circular tube 401, the surface of the insert block 405 is plugged into the square groove 2, and a reset block 405 sleeved on the surface of the guide rod 403 is fixedly installed on the side of the slider 404 away from the first circular tube 401 Spring 406, the side of the return spring 406 away from the slider 404 is fixedly connected to the triangular block 402, the end of the return spring 406 away from the triangular block 402 is fixedly connected to the first circular tube 401, the first circular tube 401 is provided with a socket 407, the surface of the plug block 405 is plugged into the socket 407, a vertical rod 408 is fixedly installed on the top of the triangular block 402, a cylinder 409 is sleeved on the surface of the vertical rod 408, a circular plate 410 is fixedly installed on the surface of the cylinder 409 and near its bottom surface, a linkage rod 411 is hinged on the bottom of the circular plate 410, and a linkage rod 411 is hinged on the top of the slider 404.

[0038] The top of the hexagonal block 3 of the present invention is provided with a reinforcement component 4, and the sleeve 7 drives the hexagonal block 3 to rotate by using the connecting plug-in. The hexagonal block 3 and the hexagonal groove cooperate to drive the drill rod 1 to rotate, and the drill rod 1 is drilled. At the same time, the reinforcement component 4 in the connecting plug-in will also rotate, and the first round tube 401 and the triangular block 402 cooperate to drive the guide rod 403 to rotate. The slider 404 on the surface of the guide rod 403 is affected by the centrifugal force of rotation and moves in the direction away from the triangular block 402. The guide rod 403 and the socket 407 cooperate to guide the slider 404, so that the plug block 405 originally inserted into the square groove 2 is inserted deeper, and the first round tube 401 is placed with the plug block 4 05 is disengaged, and centrifugal force is used to increase the connection firmness. In the non-drilling state, the insertion depth of the plug 405 is shallow. The operator only needs to press the plug 405 toward the inside of the first circular tube 401 to separate the plug 405 from the square groove 2, that is, the drill rod 1 is separated from the connecting plug. When the drill rod is severely worn and the drilling efficiency is affected, it is convenient to replace the drill rod 1 because it is not welded at the joint. The second cylindrical block 605 is sleeved with the second circular tube 501, which not only facilitates the downward movement of the second circular tube 501, but also prevents external water from entering the interior of the connecting plug. The above structure solves the problem of connection by welding and surfacing at the joint, which is difficult to replace after wear.

[0039] Embodiment 2:

[0040] See also Figure 4-6, combined with the basis of Example 1, the difference is that the speed component 5 includes a second round tube 501, and the upper and lower sides of the second round tube 501 are fixedly installed with a closing plate 502, and the side facing the closing plate 502 is fixedly installed with a guide tube 503, and the inner wall of the guide tube 503 is slidably connected with a first cylindrical block 504, and the inner wall of the first cylindrical block 504 is provided with a circular groove 505 that runs through the diameter, and the inner wall of the guide tube 503 is provided with a rubber ball 506, and the bottom of the first cylindrical block 504 is fixedly installed with a telescopic rod 507, and the bottom of the first cylindrical block 504 A buffer spring 508 is fixedly installed and sleeved on the surface of the telescopic rod 507. The bottom of the telescopic rod 507 is fixedly connected to the cylinder 409. The bottom of the buffer spring 508 is fixedly connected to the cylinder 409. A connecting rod 509 is fixedly installed on the top of the first cylindrical block 504. The inner wall of the first cylindrical block 504 and the circular groove 505 are engaged with the rubber ball 506. The connecting rod 509 passes through the closing plate 502 located on the top of the second circular tube 501. The bottom of the closing plate 502 is fixedly connected to the first circular tube 401. The inner wall of the guide tube 503 is slidably connected to the cylinder 409.

[0041] In the present invention, a speed component 5 is arranged on the top of the reinforcement component 4. When the drill rod 1 is drilling, the slider 404 is subjected to the centrifugal force, and its position on the surface of the guide rod 403 changes. The higher the drilling efficiency, the faster the speed of the drill rod 1, and the farther the distance between the slider 404 and the triangular block 402. When the speed of the drill rod 1 is slow, the centrifugal force on the slider 404 becomes smaller, and the return spring 406 pulls the slider 404 to the position of the triangular block 402. The slider 404 uses the linkage rod 411 to push the annular plate 410 upward, so that the cylinder 409 moves upward, the vertical rod 408 guides the cylinder 409, and the cylinder 409 uses the buffer spring 508 to push The first cylindrical block 504 moves, but because the rubber ball 506 uses the circular groove 505 to clamp the first cylindrical block 504, the first cylindrical block 504 will not move immediately due to the elastic force of the buffer spring 508. When the cylinder 409 moves upward to make the telescopic rod 507 completely contracted, the telescopic rod 507 pushes the first cylindrical block 504 upward. At this time, the resistance generated by the rubber ball 506 on the first cylindrical block 504 is smaller than the thrust of the first cylindrical block 504, and the telescopic rod 507 moves upward. The contraction distance of the telescopic rod 507 is used as a buffer, and the contraction distance of the telescopic rod 507 is used to distinguish the speed of the rotation. The above structure solves the problem of being unable to judge the drilling speed.

[0042] Embodiment 3:

[0043] Please refer to Figures 6-7. The difference between the embodiment 2 and the embodiment 2 is that the wave assembly 6 includes a piston 601, the surface of the piston 601 is slidably connected to the hydraulic pipe 602, and hydraulic oil is provided inside the hydraulic pipe 602 and at the bottom of the piston 601. The back of the hydraulic pipe 602 is connected to the return pipe 603, and the left and right sides of the return pipe 603 are fixedly installed with hydraulic push rods 604. The top of the hydraulic push rod 604 is fixedly installed with a second cylindrical block 605, and the top of the second cylindrical block 605 is fixedly installed with a bar block 606. The top of the bar block 606 is fixedly installed with a connecting plate 607, and the top of the connecting plate 607 is fixedly installed with a round table 608, and the top of the round table 608 is plugged with the sleeve 7. The bottom of the piston 601 is fixedly connected to the connecting rod 509, the top of the closing plate 502 is fixedly connected to the hydraulic pipe 602, and the surface of the second cylindrical block 605 is sleeved with the second round pipe 501.

[0044] In the present invention, a fluctuation component 6 is arranged on the top of the speed component 5. When the speed of the drill pipe 1 is slow, the first cylindrical block 504 moves to drive the connecting rod 509 to move upward, and the connecting rod 509 drives the piston 601 to move upward. The hydraulic oil flows back to the inside of the hydraulic pipe 602, and the hydraulic oil inside the hydraulic push rod 604 becomes less, and the hydraulic push rod 604 contracts and drives the closing plate 502 to move upward, so that the drill pipe 1 moves upward, and the drill pipe 1 takes out the gravel produced by drilling. Then, the speed of the drill pipe 1 returns to normal, and the centrifugal force exerted on the slider 404 increases, and the hydraulic push rod 604 extends downward, so that the drill pipe 1 moves downward again. When the speed of the drill pipe 1 slows down, the drill pipe 1 will move upward to take out the gravel, so as to maintain the drilling efficiency. The strip block 606, the connecting plate 607 and the round table 608 are used to dock with the sleeve 7, and the sleeve 7 provides a driving force to rotate the drill pipe 1. The above structure solves the problem that the friction caused by the gravel produced by drilling increases, resulting in a slow drilling efficiency.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
