Abstract
Description
Technical Field
[0001] This application relates to the field of anchor drilling rig technology, and in particular to an anchor bolt connecting device and an anchor drilling rig. Background Technology
[0002] Anchor drilling rigs are a key construction equipment widely used in slope protection and tunnel construction.
[0003] When constructing long, deep holes, the limited length of a single drill rod necessitates the splicing of drill rods. Existing anchor bolt drilling rigs primarily employ two splicing methods: manual splicing and automated mechanical splicing. The former involves the drilling rig being equipped with a drill rod magazine and a robotic arm, which automatically splices the drill rods, offering convenience and speed. However, the currently used rotary drum drill rod magazine structure is bulky, complex, requires high control standards, and is costly. In space-constrained environments such as tunnels, the large drill rod magazine restricts the product's working range. Furthermore, ensuring the safety of the robotic arm's splicing operation is challenging. Utility Model Content
[0004] The purpose of this application is to provide a rod extension device and an anchor drilling rig, which solves the problems of traditional rod extension devices being bulky and difficult to ensure the safety of the rod extension process.
[0005] To achieve the above objectives, this application provides a pole-connecting device, comprising:
[0006] The drill pipe magazine is flat and is used to store drill pipes arranged in the first direction. The drill pipe magazine has a drop opening for the drill pipes to be dropped.
[0007] The rod receiving mechanism is movable relative to the drill pipe magazine in a second direction perpendicular to the first direction. The rod receiving mechanism has a gripping position and a non-gripping position in the second direction. The rod receiving mechanism is configured to block the rod drop opening when in the non-gripping position and to open the rod drop opening and grip the drill pipe falling from the rod drop opening when in the gripping position.
[0008] In some embodiments, the non-grabbing position includes an initial position and a rod-attaching position. The rod-attaching mechanism includes a slide bar movably disposed at the bottom of the drill pipe magazine. The slide bar is used to block the rod drop opening when the rod-attaching mechanism is in the initial position and the rod-attaching position.
[0009] In some embodiments, the rod-attaching mechanism further includes a gripper rotatably disposed on the slide bar, the gripper being used to hold the falling drill rod.
[0010] In some embodiments, the jaws and the slide bar form a receiving groove for receiving the drill rod falling from the drop hole, and the size of the receiving groove is adjusted by rotating the jaws relative to the slide bar.
[0011] In some embodiments, the connecting rod device further includes:
[0012] The first drive mechanism is connected to the slide bar and is used to drive the slide bar to move in the second direction;
[0013] The second drive mechanism, connected to the slide bar and the gripper, is used to drive the gripper to rotate relative to the slide bar.
[0014] In some embodiments, the drill pipe magazine has a rod loading cavity and a sliding groove. The rod loading cavity extends along a first direction to allow drill pipes to be arranged along the first direction, and the sliding groove extends along a second direction to allow the rod receiving mechanism to slide along the second direction. The sliding groove is located below the rod loading cavity and communicates with the rod loading cavity.
[0015] In some embodiments, the drill pipe magazine has a flared end away from the rod insertion mechanism, which communicates with the rod loading cavity for installing the drill pipe into the rod loading cavity.
[0016] In some embodiments, a pressure regulating mechanism is provided at the flared end to provide pressure to the drill rod in the rod loading cavity, so as to prevent the drill rod from falling off the flared end and to ensure that the drill rod in the rod loading cavity falls from the rod drop outlet.
[0017] In some embodiments, the rod extension device further includes a connecting frame for connecting to the anchor drilling rig to install the drill rod magazine and the rod extension mechanism onto the anchor drilling rig.
[0018] This application also provides an anchor drilling rig, including the rod extension device described in any of the above claims.
[0019] Compared to the aforementioned background technology, the rod receiving device provided in this application includes a drill rod magazine and a rod receiving mechanism. The drill rod magazine is flat and is used to store drill rods arranged along a first direction. The drill rod magazine has a drop opening for the drill rods to fall. The rod receiving mechanism is movable relative to the drill rod magazine along a second direction perpendicular to the first direction. The rod receiving mechanism has a gripping position and a non-gripping position in the second direction. The rod receiving mechanism is configured to block the drop opening when in the non-gripping position and to open the drop opening and grip the drill rod falling from the drop opening when in the gripping position.
[0020] The advantages of this type of connecting rod device mainly include:
[0021] On the one hand, compared with the traditional rotary drum drill pipe magazine, the drill pipe magazine of this application is flat or has a magazine-like structure, which greatly reduces the size of the drill pipe magazine in the second direction (i.e., the lateral direction). It can compactly store a large number of drill pipes in a limited space, thereby greatly reducing the volume of the drill pipe magazine and eliminating the need for a complex drum structure, thus reducing manufacturing and installation costs.
[0022] On the other hand, the rod-joining method, which uses a rod-joining mechanism that moves along the second direction, not only improves the rod-joining speed and enables batch rod replacement, avoiding the inefficiency and safety hazards of manual operation, but also allows the rod drop opening to be blocked at non-grabbing positions to ensure stable storage of drill rods and prevent accidental slippage. When a rod needs to be retrieved, it is moved to the grabbing position, the rod drop opening is opened, and the dropped drill rod is accurately grabbed, achieving fast and orderly drill rod storage and retrieval, which greatly improves the efficiency of rod-joining operations and the safety of the rod-joining process.

[0042] The rod-connecting device provided in this application embodiment includes a drill rod magazine 10 and a rod-connecting mechanism 20.
[0043] The drill pipe magazine 10 is flat or has a magazine-like structure. The drill pipe magazine 10 is used to store drill pipes 50 arranged along the first direction. The bottom of the drill pipe magazine 10 has a drop opening 11 for the drill pipes 50 to fall down.
[0044] The rod receiving mechanism 20 is movable relative to the drill pipe magazine 10 in a second direction perpendicular to the first direction. The rod receiving mechanism 20 has a gripping position and a non-gripping position in the second direction. The rod receiving mechanism 20 is configured to block the rod drop port 11 in the non-gripping position and open the rod drop port 11 and grip the drill pipe 50 falling from the rod drop port 11 in the gripping position.
[0045] It should be noted that the first direction mentioned above is as follows: Figure 2 The vertical direction shown is the second direction, which is as follows: Figure 2 The horizontal direction is shown.
[0046] On the one hand, compared with the traditional rotary drum type drill pipe magazine 10, the drill pipe magazine 10 of this application is flat or has a magazine-like structure, which greatly reduces the size of the drill pipe magazine 10 in the second direction (i.e., the transverse direction), and can compactly store a large number of drill pipes 50 in a limited space, thereby greatly reducing the volume of the drill pipe magazine 10, and eliminating the need for a complex drum structure, thus reducing manufacturing and installation costs.
[0047] On the other hand, the rod-joining method using the rod-joining mechanism 20 moving in the second direction not only improves the rod-joining speed and enables batch rod replacement, avoiding the inefficiency and safety hazards of manual operation, but also allows the rod-dropping opening 11 to be blocked at non-grabbing positions, ensuring the stable storage of the drill rod 50 and preventing the drill rod 50 from accidentally slipping. When the rod needs to be retrieved, it is moved to the grabbing position, and the rod-dropping opening 11 is opened to accurately grab the fallen drill rod 50, achieving fast and orderly storage and retrieval of the drill rod 50, which greatly improves the efficiency of the rod-joining operation and the safety of the rod-joining process.
[0048] Of course, depending on actual needs, multiple rod-connecting mechanisms 20 can be set along the length of the drill rod 50, and the multiple rod-connecting mechanisms 20 can be set at intervals to ensure the stability of the drill rod 50 in gripping and conveying.
[0049] In some embodiments, the non-grabbing position includes an initial position and a rod-attaching position. The initial position refers to the position of the rod-attaching mechanism 20 before grabbing, and the rod-attaching position refers to the preset rod-attaching position that the rod-attaching mechanism 20 needs to reach after grabbing the drill rod 50, at which the drilling rig performs the rod-attaching operation of the drill rod 50.
[0050] The rod receiving mechanism 20 includes a slide bar 21, which is movably disposed at the bottom of the drill pipe magazine 10. The slide bar 21 is used to block the rod drop opening 11 when the rod receiving mechanism 20 is in the initial position and the rod receiving position.
[0051] In other words, when the rod-connecting mechanism 20 is in the initial position and the rod-connecting position, the slide bar 21 is always located below the rod-dropping opening 11 and blocks the rod-dropping opening 11, so that the drill rod 50 in the drill rod magazine 10 will not fall.
[0052] To facilitate the gripping of the drill rod 50, the rod receiving mechanism 20 also includes a gripper 22, which is rotatably mounted on the slide bar 21 and is used to grip the falling drill rod 50.
[0053] In some embodiments, the gripper 22 and the slide bar 21 form a receiving groove 23 for receiving the drill rod 50 falling from the drop hole 11. The size of the receiving groove 23 can be adjusted by rotating the gripper 22 relative to the slide bar 21.
[0054] For example, after the rod-receiving mechanism 20 moves backward from its initial position to the gripping position, the jaws 22 flip forward to enlarge the receiving groove 23, thus facilitating the drill rod 50 to fall into the receiving groove 23. Then, the jaws 22 flip backward to clamp the falling drill rod 50. After the rod-receiving mechanism 20 moves forward from the gripping position to the rod-receiving position, the jaws 22 flip forward to release the drill rod 50, facilitating the rod-receiving operation by the drilling rig. After the rod is received, the jaws 22 flip backward to the position before gripping.
[0055] To facilitate the driving of the slide bar 21, the connecting rod device also includes a first driving mechanism, which is connected to the slide bar 21 and is used to drive the slide bar 21 to move along the second direction.
[0056] To facilitate the driving of the gripper 22, the connecting rod device also includes a second driving mechanism. The second driving mechanism is connected to the slide bar 21 and the gripper 22. The second driving mechanism is used to drive the gripper 22 to rotate relative to the slide bar 21.
[0057] Of course, depending on actual needs, both the first and second drive mechanisms can be configured as cylinder or hydraulic cylinder assemblies.
[0058] In some embodiments, the drill pipe magazine 10 is provided with a rod loading cavity 12 and a sliding groove 13. The rod loading cavity 12 extends along a first direction so that the drill pipes 50 are arranged in a straight line along the first direction. The sliding groove 13 extends along a second direction so that the rod receiving mechanism 20 slides along the second direction. The sliding groove 13 is located below the rod loading cavity 12 and communicates with the rod loading cavity 12.
[0059] In this way, the lever-connecting mechanism 20 can switch between the initial position, the gripping position and the lever-connecting position by sliding in the sliding groove 13.
[0060] In some embodiments, the drill pipe magazine 10 is provided with a flared end 14 at the end away from the rod receiving mechanism 20. The flared end 14 refers to the flared end whose dimensions in the second direction gradually decrease in the direction close to the rod receiving mechanism 20. The flared end 14 communicates with the rod mounting cavity 12 so that the drill pipe 50 can be installed in the rod mounting cavity 12.
[0061] It can be seen that the flared structure 14 has a guiding function, and the drill rod 50 can be easily stored in the rod loading cavity 12 through the structure of the flared structure 14.
[0062] In some embodiments, a pressure regulating mechanism 30 is provided at the flared opening 14. The pressure regulating mechanism 30 is used to provide pressure to the drill rod 50 in the rod loading cavity 12 to prevent the drill rod 50 from falling off the flared opening 14 and to ensure that the drill rod 50 in the rod loading cavity 12 falls from the rod dropping opening 11.
[0063] Specifically, the constant pressure mechanism 30 includes a fixed seat, a pressure rod, and an elastic element. The fixed seat is fixed at the flared opening 14. One end of the pressure rod extends downward from the fixed seat and contacts the drill rod 50. The elastic element abuts between the fixed seat and the pressure rod. The elastic element can be a spring, which is used to provide elastic force to the pressure rod so that the pressure rod always has a downward pressing tendency. This not only prevents the drill rod 50 from falling off the flared opening 14, but also ensures that the drill rod 50 in the rod mounting cavity 12 falls smoothly from the rod dropping opening 11 under the pressure of the pressure rod.
[0064] In some embodiments, the rod-connecting device further includes a connecting frame 40 for connecting to the anchor drilling rig to install the drill rod magazine 10 and the rod-connecting mechanism 20 onto the anchor drilling rig.
[0065] The working process of the rod extension device is explained in detail below:
[0066] When the anchor drilling rig is drilling, the rod-connecting mechanism 20 blocks the rod drop opening 11 at the bottom of the drill rod magazine 10 to prevent the drill rod 50 from falling due to its own weight. When it is necessary to continue connecting the drill rod 50, the rod-connecting mechanism 20 moves laterally to the gripping position, and the lowest drill rod 50 falls into the receiving groove 23 of the rod-connecting mechanism 20, and the gripper 22 clamps the falling drill rod 50. Then, the rod-connecting mechanism 20 extends, and at the same time as extending, it blocks the rod drop opening 11 at the bottom of the drill rod magazine 10 and transports the drill rod 50 to the connecting position. After the connecting is completed, the gripper 22 of the rod-connecting mechanism 20 releases the drill rod 50 and returns to the initial position.
[0067] The rod-connecting device with the above-mentioned setup is suitable for long and deep hole construction scenarios, and is especially suitable for engineering needs where the drill rod 50 is long and the rod-connecting frequency is high.
[0068] The anchor drilling rig provided in this application includes the rod connecting device described in the above specific embodiments; other parts of the anchor drilling rig can be referred to in related technologies, and will not be elaborated here.
[0069] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0070] The above provides a detailed description of the rod-connecting device and anchor drilling rig provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
