Description

Technical Field

[0001] This utility model relates to the field of RC drilling rigs, and in particular to a mechanism for automatically attaching and detaching drill rods in an RC air reverse circulation drilling rig. Background Technology

[0002] As a core piece of equipment in fields such as geotechnical engineering exploration and mineral resource exploration, the connection and disconnection of drill rods are key processes in drilling operations, directly affecting drilling efficiency, construction safety, and operational continuity. An efficient and stable connection and disconnection mechanism for drill rods can significantly reduce downtime and manpower dependence, which is of great practical significance for ensuring the high-quality progress of exploration projects.

[0003] In the existing technology, the connection and disconnection of drill rods mostly rely on manual labor and simple auxiliary tools. During the operation, the operator needs to first hoist the drill rod to be connected to the designated position, manually align the interface, and then tighten it with tools such as wrenches. When disconnecting, the operation is reversed. The drill rod connection threads are loosened by manually applying external force, and then the removed drill rod is transferred to the storage area.

[0004] The existing technology has the following drawbacks: during construction operations, due to the large weight of the drill rod and the complex stress on the connection parts, improper operation during manual alignment and tightening can easily lead to the drill rod slipping or the threads getting stuck, which can cause safety accidents such as personnel injury and equipment collision, seriously threatening the personal safety of construction personnel. To address these issues, a mechanism for automatically connecting and disconnecting drill rods for RC air reverse circulation drilling rigs is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mechanism for automatically attaching and detaching drill rods in RC air reverse circulation drilling rigs, aiming to solve the problems of poor safety and high manual labor intensity during operation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mechanism for automatically attaching and detaching drill rods in an RC air reverse circulation drilling rig, comprising a longitudinal slide beam, a longitudinal slide block slidably connected to the outer wall of the longitudinal slide beam, a vertical slide rod fixedly connected to the right side wall of the longitudinal slide block, a bidirectional slide block slidably connected to the outer wall of the vertical slide rod, a horizontal slide beam slidably connected to the inner wall of the bidirectional slide block, a rotary support fixedly connected to the left end of the horizontal slide beam, a fixed plate fixedly connected to the movable end of the rotary support, a clamp hinged to the left side wall of the fixed plate, and a drill rod contacting the left side wall of the fixed plate.

[0007] As a further description of the above technical solution:

[0008] The inner wall of the gripper is provided with rollers.

[0009] As a further description of the above technical solution:

[0010] The gripper is provided in two sets, and the two sets of grippers are arranged symmetrically.

[0011] As a further description of the above technical solution:

[0012] The gripper has an arc-shaped interior.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the gripper is in contact with the outer wall of the drill pipe.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the roller is in contact with the outer wall of the drill pipe.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, relying on a three-dimensional motion mechanism, the drill rod chuck can achieve precise displacement in the front-back, up-down, and left-right directions. Combined with the 360° rotation adjustment of the slewing support, the drill rod and the power head can be quickly and accurately aligned, greatly improving the efficiency of drill rod connection and disconnection. In addition, the unique design of the chuck with a straight plate inserted on one side and a semi-circular arc clamping on the other side ensures stable clamping of the double-wall structure drill rod, avoids the risk of slippage during operation, and ensures operation accuracy and equipment safety.

[0019] 2. In this utility model, no manual labor is required to lift and transport the drill pipe throughout the entire process, which completely reduces the labor intensity of employees and eliminates the safety hazards caused by manual operation. At the same time, the structural design is adapted to the intelligent control system upgrade, which can realize unmanned automated continuous operation, reduce human intervention, improve the safety and stability of the operation process, further optimize the construction process, and adapt to the needs of large-scale and efficient drilling operations.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a mechanism for automatically attaching and detaching drill rods in an RC air reverse circulation drilling rig. The mechanism includes a longitudinal slide beam 1, which serves as the core support component of the overall mechanism, providing a stable front-to-back sliding track for the longitudinal slide block 2, ensuring the movement accuracy of the mechanism in the longitudinal direction. The longitudinal slide block 2 is slidably connected to the outer wall of the longitudinal slide beam 1. A vertical slide rod 3 is fixedly connected to the right side wall of the longitudinal slide block 2. The connection between the longitudinal slide block 2 and the vertical slide rod 3 is secured with high-strength bolts to ensure the connection stability under stress. A bidirectional slide block 4 is slidably connected to the outer wall of the vertical slide rod 3. The bidirectional slide block 4 is connected to the vertical slide rod 3 and a horizontal sliding beam 5. The slide block 4 can move up and down along the vertical slide rod 3, thereby adjusting the height position of the drill rod 10. A horizontal sliding beam 5 is slidably connected to the inner wall of the bidirectional slide block 4. The horizontal sliding beam 5 is installed on the bidirectional slide block 4 and can move horizontally left and right along the bidirectional slide block 4 to adjust the left and right distance of the drill rod 10. A rotary support 6 is fixedly connected to the left end of the horizontal sliding beam 5. The rotary support 6 has a built-in drive motor, which allows the rotary support 6 to drive the drill rod 10 to rotate 360°. A fixed plate 7 is fixedly connected to the movable end of the rotary support 6. A gripper 8 is hinged to the left side wall of the fixed plate 7. The gripper 8 uses the linkage mechanism principle to grip and release the drill rod 10. The left side wall of the fixed plate 7 contacts the drill rod 10.

[0028] Reference Figures 2-4 The inner wall of the gripper 8 is equipped with rollers 9, which are wrapped with wear-resistant rubber material, providing both cushioning and anti-slip effects. The outer wall of the rollers 9 contacts the outer wall of the drill rod 10, and the contact points are evenly distributed to avoid excessive local pressure.

[0029] Reference Figures 1-3 The chucks 8 are provided in two sets, which are symmetrically arranged to ensure a balanced distribution of clamping force. The inside of the chucks 8 is arc-shaped, and the radius of the arc is precisely matched with the outer diameter of the drill rod 10, resulting in a very high degree of fit. The inner wall of the chucks 8 contacts the outer wall of the drill rod 10, and the contact surface is provided with anti-slip texture to further enhance the clamping firmness.

[0030] Working principle: When adding drill rod 10, the longitudinal slide 2 moves back and forth along the longitudinal slide beam 1, cooperating with the bidirectional slide 4 sliding up and down along the vertical slide rod 3 and the horizontal slide beam 5 adjusting left and right along the bidirectional slide 4. The three work together to drive the rotary support 6 and the chuck 8 to move precisely above the drill rod 10. As the fixing plate 7 moves downward, it inserts into the gap of the drill rod 10. At the same time, the arc surface of the chuck 8 fits against the outer wall of the drill rod 10 to grip and firmly hold the drill rod 10. Subsequently, the bidirectional slide 4 raises the drill rod 10 to a height of more than 1.5 meters. Then, the drive motor built into the rotary support 6 drives the drill rod 10 to rotate 360° so that it is parallel to the front end of the drilling rig mast. Then, the three-dimensional adjustment mechanism sends the drill rod 10 to a suitable position at the front of the mast and aligns the drill rod 10 with the center of the drilling rig power head. After the power head rotates downward to complete the connection, the chuck 8 releases and retracts in the opposite direction, ready to grab the next drill rod 10.

[0031] During the unloading operation, the drill rig's power head first pulls the drill rod 10 out of the hole and initially disconnects it from the direct connection. Then, the rod-adding mechanism, through the multi-dimensional adjustment of the aforementioned adjustment mechanism, sends the clamp 8 to the vicinity of the drill rod 10 and clamps it in place. After the power head further reverses to completely disconnect from the drill rod 10, the clamp 8 will drive the drill rod 10 to move backward. At the same time, the slewing support 6 will rotate the drill rod 10 to a horizontal position. Then, through the three-dimensional adjustment mechanism, the drill rod 10 is moved to the designated placement position. Finally, the clamp 8 is released, completing the unloading process of a single drill rod 10. By repeating the above operation, all drill rods 10 can be added or disconnected in sequence. The entire process requires no manual lifting and transportation, combining high efficiency and safety.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
