[0051] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0052] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0053] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0054] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0055] like Figures 1 to 9 As shown, the present invention provides a drill rod transport device suitable for a polar box-type drilling rig, which includes a storage box 1 and a working box 2 that are interconnected. A storage rack 11 for placing drill rods 3 and a clamping assembly 12 for transporting drill rods 3 are provided in the storage box 1. A drill rod grabbing manipulator 21, an intermediate reversing assembly 22, and a drilling rig 23 are provided on the working box 2; the drill rod grabbing manipulator 21 is provided on the top surface of the working box 2; the intermediate reversing assembly 22 includes a reversing wheel 221 that is rotatably provided in the working box 2, and the reversing wheel 221 is located between the clamping assembly 12 and the drill rod grabbing manipulator 21, with the centerline of the reversing wheel 221 being perpendicular to the length direction of the working box 2. The clamping element 121 can drive the drill rod 3 to move so that the first end of the drill rod 3 abuts against the reversing wheel 221; the drill rod 3 can move to the waiting state under the action of the reversing wheel 221. At this time, the first end of the drill rod 3 extends out of the working box 2 and approaches the drill rod grabbing manipulator 21, and the drill rod grabbing manipulator 21 can clamp and drive the drill rod 3 to move.

[0056] In actual polar environment, the working box 2 and the storage box 1 are generally containers, which facilitates transportation. Due to the size limitations of the working box 2 and the storage box 1, the drill rod 3 is generally placed horizontally (the length direction of the drill rod 3 is consistent with the length direction of the container) in the storage box 1, and the storage box 1 and the working box 2 are connected in the length direction. When the drilling rig 23 is working, the center line of the drilling rig 23 and the center line of the drill rod 3 are vertical. This causes the drill rod 3 in the storage box 1 to be in a vertical state when in use or stored. Therefore, the drill rod 3 also involves a posture change from horizontal to vertical during the movement process. Due to size limitations, the drill rod grabbing robot 21 on the working box 2 cannot penetrate into the interior of the working box 2, and the flipping angle is not too large. Therefore, the solution of the present invention is to set a rotating reversing wheel 221 in the working box 2. When the first end of the drill rod 3 in the storage box 1 is moved by the clamping assembly 12 to abut against the reversing wheel 221, it is only necessary to push the drill rod 3 along the tangential direction of the rotation of the reversing wheel 221. The drill rod 3 will generate rolling friction with the reversing wheel 221, and the inclination angle of the drill rod 3 will gradually increase. The height of the first end of the drill rod 3 will gradually increase. The first end of the drill rod 3 will eventually extend out of the working box 2 and be located on one side of the drill rod grasping manipulator 21. The drill rod grasping manipulator 21 clamps the drill rod 3, flips it at a certain angle so that the drill rod 3 is in a vertical state and drives the drill rod 3 to move. In summary, the present invention clamps and moves the drill rod 3 by setting a clamping assembly 12 in the storage box 1, avoiding the user from directly carrying the drill rod 3 by hand, thereby reducing the workload. In addition, a reversing wheel 221 is provided in the working box 2 to reverse the drill rod 3, so that the drill rod 3 is converted from a flat state to an inclined state, and at the same time the drill rod 3 is transferred to one side of the drill rod grabbing manipulator 21, so that the drill rod grabbing manipulator 21 can clamp and drive the drill rod 3 to flip and move, thereby reducing the difficulty of transferring the drill rod 3.

[0057] Furthermore, the clamping assembly 12 includes a guide element and a clamping element 121; the guide element is installed in the storage box 1; the guide element can be two guide rails and a slider (i.e., an X guide rail, a Y guide rail and a slider) arranged in the storage box 1, wherein the X guide rails are paired and arranged in parallel, the direction of the X guide rail is the X direction, the Y guide rail is slidably arranged on the X guide rail, and the Y guide rail can move along the length direction of the X guide rail, the length direction of the Y guide rail is the Y direction, the slider is slidably arranged on the Y guide rail, and the slider can move along the length direction of the Y guide rail, the X direction and the Y direction are perpendicular, and the slider is used to connect with the clamping element 121, so that the two arc-shaped clamping jaws 124 in the clamping element 121 can move arbitrarily in the horizontal plane, thereby achieving the purpose of moving the drill rod 3.

[0058] The clamping element 121 includes a clamping rod 122, a clamping frame 123, and a pair of arc-shaped clamping claws 124. The clamping rod 122 is slidably disposed within the clamping frame 123, and the clamping rod 122 can move relative to the clamping frame 123 along the Z direction.

[0059] A rotating shaft 1221 is provided at the first end of the clamping rod 122, and a first hinge shaft 1231 and a second hinge shaft 1232 are provided on the clamping frame 123. A waist-shaped hole 1241 is provided at the first end of the arc-shaped clamping jaw 124, and the rotating shaft 1221 is inserted into the waist-shaped hole 1241. One of the two arc-shaped clamping jaws 124 is hinged to the clamping frame 123 via the first hinge shaft 1231, and the other of the two arc-shaped clamping jaws 124 is hinged to the clamping frame 123 via the second hinge shaft 1232. The second ends of the two arc-shaped clamping jaws 124 can abut against each other to form a columnar receiving section 125 to clamp the drill rod 3.

[0060] The second end of the clamping rod 122 is connected to the guide element via a connecting rope 120 , and the guide element can drive the clamping element 121 to move in the storage box.

[0061] In the above solution, during the movement of the drill rod 3, due to the gravity of the gripping frame 123 and the curved clamping jaws 124, the gripping frame 123 moves downward in the vertical direction relative to the gripping rod 122. The gripping frame 123 causes the two curved clamping jaws 124 to rotate about the first hinge axis 1231 and the second hinge axis 1232, respectively. The second ends of the two curved clamping jaws 124 abut against each other to form a cylindrical receiving section 125 to grip the drill rod 3. When the drill rod 3 needs to be lowered, the gripping frame 123 is simply lifted upward to move the two curved clamping jaws 124 away from each other, allowing the drill rod 3 to be lowered.

[0062] Furthermore, during the aforementioned movement of the drill rod 3, a buckle 1233 can be provided to ensure that the second ends of the two arc-shaped clamping jaws 124 are always in contact, thereby ensuring stability during the movement process. An annular groove 1222 is provided on the surface of the clamping rod 122 that contacts the clamping frame 123. A buckle 1233 is rotatably provided on the clamping frame 123. The first end of the buckle 1233 can extend into the annular groove 1222 to limit the displacement of the clamping rod 122 within the clamping frame 123.

[0063] The specific usage process is as follows: when it is necessary to clamp the drill rod 3, the clamping frame 123 is lifted upward. At this time, the clamping frame 123 moves upward relative to the clamping rod 122, and the second ends of the two arc-shaped clamping claws 124 move away from each other. After the drill rod 3 is located in the two arc-shaped clamping claws 124, the clamping frame 123 is lowered, and the second ends of the two arc-shaped clamping claws 124 approach and abut each other, and the buckle 1233 is pressed (or released). The first end of the buckle 1233 extends into the annular groove 1222. At this time, the clamping rod 122 and the clamping frame 123 are locked with each other, and the clamping rod 122 cannot be displaced relative to the clamping frame 123, and the two arc-shaped clamping claws 124 cannot rotate, thereby realizing the arc-shaped clamping claws 124 to firmly grasp the drill rod 3. When the drill rod 3 needs to be lowered, the user only needs to release (or press) the buckle 1233, allowing the first end of the buckle 1233 to exit the annular groove 1222. The arcuate clamping jaws 124, under the action of the weight of the drill rod 3, will pull the clamping rod 122 downward, causing the clamping frame 123 to move upward relative to the clamping rod 122. The second ends of the two arcuate clamping jaws 124 move away from each other, releasing the drill rod 3. In this solution, the user can achieve self-locking and releasing of the two arcuate clamping jaws 124 simply by operating the buckle 1233, simplifying the process of transferring the drill rod 3.

[0064] In a preferred embodiment, an elastic member 1234 is further disposed between the clamping frame 123 and the buckle 1233. One end of the elastic member 1234 abuts the clamping frame 123, while the other end abuts the second end of the buckle 1233. In this embodiment, the first end of the buckle 1233 is constantly in contact with the clamping rod 122 due to the action of the elastic member 1234. Furthermore, the outer surface of the second end of the buckle 1233 extends beyond the surface of the clamping frame 123. A user only needs to press the second end of the buckle 1233 to move the first end of the buckle 1233 away from the clamping rod 122.

[0065] In addition, the first side of the storage box 1 is opposite to the first side of the working box 2. A pair of first connecting doors 13 rotating around a first rotating axis are provided on the first side of the storage box 1, and a pair of second connecting doors 24 rotating around a second rotating axis are provided on the first side of the working box 2. The first rotating axis and the second rotating axis are perpendicular, and when the first connecting door 13 and the second connecting door 24 are both opened, the first connecting door 13 and the second connecting door 24 can form a rectangular connecting channel 4. The rectangular connecting channel 4 is used to connect the storage box 1 and the working box 2. The drill rod 3 in the storage rack 11 can be transferred to the working box 2 through the clamping assembly 12; a drilling rig 23 and a placing rack 25 for placing the drill rod 3 are provided in the working box 2. The placing rack 25 includes a plurality of finger beams 26 arranged in parallel in the working box 2, and two adjacent finger beams 26 are used to limit the swing of the drill rod 3 when it is placed.

[0066] This solution connects the box for storing the drill rod 3 and the box for installing the drilling rig 23 together, and the rotating axes 1221 of the first connecting door 13 on the storage box 1 and the second connecting door 24 on the working box 2 are different. When the first connecting door 13 and the second connecting door 24 are opened, a rectangular connecting channel 4 can be formed, which is convenient for the user to move the drill rod 3, and can also isolate the wind and snow in the polar environment, making the user's working environment more comfortable.

[0067] The work box 2 houses a drilling rig 23 and a rack 25 for placing drill rods 3. The rack 25 includes multiple finger beams 26 arranged parallel to the work box 2. Two adjacent finger beams 26 are used to limit the swing of the drill rods 3 when placed. When placing the drill rods 3, they are placed vertically within the work box 2. At this time, the three finger beams 26 are perpendicular, and the drill rod 3 is located between two adjacent finger beams 26. Therefore, the two adjacent finger beams 26 are used to limit the swing of the drill rod 3 when placed.

[0068] A drill rod grabbing manipulator 21 is provided on the working housing 2. The drill rod grabbing manipulator 21 includes a horizontal moving assembly 211, a flipping device 212, and a manipulator 213. The horizontal moving assembly 211 is provided on the working housing 2. The fixed end of the flipping device 212 is provided on the horizontal moving assembly 211. The movable end of the flipping device 212 is hinged to the first connection point of the manipulator 213. The second connection point of the manipulator 213 is hinged to one side of the horizontal moving assembly 211. The flipping device 212 drives the first connection point of the manipulator 213 to rotate around the second connection point so that the clamping axis of the manipulator 213 is parallel to the axis of the drill rod 3. The manipulator 213 clamps and drives the drill rod 3 to move along its axis to move the drill rod 3 away from or closer to the ground. The horizontal moving assembly 211 drives the drill rod 3 to move through the manipulator 213.

[0069] Manipulator 213 includes a fixed column 2131, a fixed jaw 2132, an active jaw 2133, a clamping cylinder 2134, and a drive element 2135. The fixed jaw 2132 and the active jaw 2133 are positioned opposite each other, with the fixed jaw 2132 fixed to the fixed column 2131 and the active jaw 2133 hinged to the fixed column 2131. The fixed end of the clamping cylinder 2134 is connected to the fixed column 2131, while the movable end of the clamping cylinder 2134 is connected to the active jaw 2133, driving the active jaw 2133 to rotate about the fixed column 2131 to cooperate with the fixed jaw 2132 to clamp the drill rod 3. A plurality of rolling wheels 2136 are correspondingly provided on the surfaces of the fixed claw 2132 and the active claw 2133 that are in contact with the drill rod 3. One of the rolling wheels 2136 is an active roller 2137. The active roller 2137 is connected to the driving element 2135, and the driving element 2135 can drive the active roller 2137 to rotate.

[0070] In this solution, the manipulator 213 is used to grab the drill rod 3 transferred from the storage box 1 and place the drill rod 3 on the display rack 25 of the working box 2 or on the drilling rig 23. The specific structure of the manipulator 213 in this solution is the structure of the drill rod grabbing manipulator 21 for the drilling rig 23 in the existing patent number CN118148524A, and will not be repeated here.

[0071] On the other hand, the intermediate reversing assembly 22 further includes a fixed rod 222, a fixed bracket 223, and a reversing bracket 224. The fixed rod 222 and the fixed bracket 223 are both disposed within the working housing 2, with the fixed bracket 223 located on one side of the fixed rod 222. The reversing bracket 224 is fixedly mounted on the fixed rod 222, and the reversing wheel 221 is rotatably mounted on the reversing bracket 224. When the drill rod 3 is in the waiting state, the first end of the drill rod 3 extends out of the working housing 2, the second end of the drill rod 3 abuts the fixed bracket 223, and the drill rod 3 abuts the reversing wheel 221.

[0072] In this embodiment, the fixed rods 222 are arranged in pairs and fixedly mounted vertically within the working box 2. By changing the mounting position of the reversing brackets 224 on the fixed rods 222, the height of the reversing wheel 221 within the working box 2 can be adjusted. In addition, a fixed bracket 223 is provided for abutting against the second end of the drill rod 3, so that the drill rod 3 is more stable when in the state to be transferred and does not slip due to tilting.

[0073] In a preferred embodiment, the top of the work box 2 is provided with multiple windows, each of which is rotatably provided with a window door 27 for controlling the opening and closing of the window. A display rack 25 is located below the window, and when the drill rig 23 is in a vertical position, one end of the drill rig 23 can extend through the window. The drill rig 23 is rotatably mounted within the work box 2 and has both a vertical and horizontal position. When the drill rig 23 is in the vertical position, one end of the drill rig 23 extends through the window and out of the top of the work box 2. When the drill rig 23 is in the horizontal position, the drill rig 23 is completely within the work box 2.

[0074] Finally, the present invention also provides a drill rod transportation method applicable to a polar box-type drilling rig.
