For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] The drill rod storage tooling and drill rod replacement equipment provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown, an embodiment of the present application discloses a drill rod storage tooling, the drill rod storage tooling 200 includes a storage box 210 and a limiting member 220, the storage box 210 has a accommodating cavity for storing the drill rod 100, the limiting member 220 can be movably arranged in the accommodating cavity, that is, the limiting member 220 can move relative to the bottom wall of the accommodating cavity, the limiting member 220 can move relative to the drill rod 100 to limit the drill rod 100 to prevent the drill rod 100 from shaking in the accommodating cavity of the storage box 210; at the same time, since the position of the limiting member 220 is adjustable, it can meet the storage requirements of various models of drill rods 100, thereby improving the versatility of the drill rod storage tooling.

[0024] Optionally, the limit member 220 can be movably disposed on the bottom wall of the accommodating cavity of the storage box 210; or, in an optional embodiment, the drill rod storage tooling 200 also includes a support frame 230 and a guide rail 250, the support frame 230 is disposed on the bottom wall of the accommodating cavity, the guide rail 250 is disposed on the support frame 230, and the limit member 220 is slidably connected to the guide rail 250, that is, the limit member 220 is disposed on the support frame 230, thereby avoiding the need to provide a slide groove on the bottom wall of the accommodating cavity, etc., to ensure the structural strength of the storage box 210 and enhance its carrying capacity; and, during the sliding process of the limit member 220, the guide rail 250 can provide guidance for the limit member 220, so that the limit member 220 slides in a preset direction to avoid the limit member 220 from tilting and causing jamming.

[0025] Optionally, the limiter 220 can be manually driven to slide relative to the guide rail 250; or, the drill rod storage tooling 200 further includes a first driving source 240, which is disposed on the support frame 230. Optionally, the support frame 230 has a connecting column 232, one end of the first driving source 240 is connected to the connecting column 232, and the output shaft of the first driving source 240 is connected to the limiter 220. The first driving source 240 can drive the limiter 220 to slide relative to the support frame 230, thereby further improving the automation performance of the drill rod storage tooling 200 and reducing human involvement. Alternatively, the limiter plate 221 and the guide rail 250 can be meshed through a gear rack to enable the limiter plate 221 to move relative to the guide rail 250.

[0026] In a further optional embodiment, the limit member 220 includes a limit plate 221 and a roller 222, the roller 222 is disposed on the limit plate 221, the roller 222 is in rolling cooperation with the guide rail 250, the limit plate 221 is in sliding cooperation with the guide rail 250 through the roller 222, and the output shaft of the first driving source 240 is connected to the limit plate 221. The roller 222 is in rolling cooperation with the guide rail 250, which can reduce the contact area between the limit member 220 and the guide rail 250, thereby reducing the friction force, so that the limit member 220 can slide more flexibly. At this time, the first driving source 240 only needs to output a small driving force to drive the limit member 220 to slide, thereby saving driving force. Of course, the limit plate 221 can also be in sliding cooperation with the guide rail 250 through a slider.

[0027] Optionally, the number of guide rails 250 is at least two, and each guide rail 250 is arranged at intervals along the length direction of the accommodating cavity. The rollers 222 and the guide rails 250 are arranged one by one, and each roller 222 and each guide rail 250 are respectively rollingly matched, thereby increasing the contact area between the limit member 220 and the guide rail 250 and improving the sliding stability of the limit member 220.

[0028] In another optional embodiment, the number of the limit members 220 is at least two, and the limit members 220 are arranged at intervals along the width direction of the accommodating cavity. The width direction of the accommodating cavity here specifically refers to the direction perpendicular to the extension direction of the drill rod 100 after the drill rod 100 is stored in the accommodating cavity. The first driving sources 240 are arranged in a one-to-one correspondence with the limiting members 220, and each first driving source 240 drives each limiting member 220 to slide. At this time, the drill rod 100 can be located between adjacent limiting members 220, and the adjacent limiting members 220 can clamp the drill rod 100, thereby limiting the drill rod 100; or, the drill rod storage tooling 200 also includes a baffle 260, and the baffle 260 is arranged between adjacent limiting members 220.

At this time, the drill rod 100 can be placed on both sides of the baffle 260, that is, two limiting members 220 can share one baffle 260, and one limiting member 220 and one baffle 260 can clamp at least one drill rod 100, thereby reducing the number of first driving sources 240, and then reducing the cost and the number of components of the drill rod storage tooling 200, and facilitating the arrangement of various components.

[0029] It should be noted that when the number of drill rods 100 between a stopper 220 and a baffle 260 is at least two, the drill rods 100 are stacked in sequence along the vertical direction.

[0030] Optionally, adjacent limiting members 220 may be arranged side by side in the length direction of the accommodating cavity of the storage box 210; or, adjacent limiting members 220 may be staggered in the length direction of the accommodating cavity of the storage box 210. When the drill rod 100 is in a limited state, the limiting members 220 act on a larger area of ​​the drill rod 100 in the length direction of the drill rod 100, which is beneficial to improving the stability of the drill rod 100.

[0031] In an optional embodiment, the support frame 230 has a guide rod 231, and the guide rod 231 is spaced apart from the guide rail 250 in the length direction of the drill rod 100. A guide groove 223 is provided on the side of the bottom surface of the stopper 220 facing the accommodating cavity, and the guide groove 223 cooperates with the guide rod 231 to prevent the stopper 220 from tilting. This solution utilizes the structure of the support frame 230 itself to provide guidance for the stopper 220, so that the support frame 230 has the efficiency of one object serving two purposes, which is conducive to improving the utilization rate of the support frame 230.

[0032] In another optional embodiment, the storage box 210 includes a box body 211 and a protective cover 212, the protective cover 212 can be covered on the box body 211 to form a accommodating cavity, and one end of the protective cover 212 can be hinged to the box body 211; or, the drill rod storage tooling 200 also includes a clamping mechanism 270, the clamping mechanism 270 is arranged on the outer surface of the drill rod storage tooling 200, one end of the clamping mechanism 270 is connected to the box body 211, and the other end of the clamping mechanism 270 is connected to the protective cover 212, the protective cover 212 is covered on the box body 211 through the clamping mechanism 270 or the box body 211 is opened to expose the drill rod 100, thereby protecting the drill rod 100 in the accommodating cavity of the storage box 210; and the clamping mechanism 270 can act on the protective cover 212 with a certain pressing force to prevent the drill rod 100 from being exposed due to road bumps during transportation.

[0033] In a further optional embodiment, the clamping mechanism 270 includes a second driving source 271 and a clamping member 272, the clamping member 272 is connected to the box body 211 and the protective cover 212 respectively, and the clamping member 272 can rotate relative to the box body 211, that is, the clamping member 272 is rotatably connected to the box body 211, the second driving source 271 is arranged on the box body 211, the output shaft of the second driving source 271 is rotatably connected to the clamping member 272, and the second driving source 271 can drive the protective cover 212 to rotate relative to the box body 211 through the clamping member 272, so that the protective cover 212 is opened or covered on the box body 211. In this scheme, the clamping member 272 is driven to rotate relative to the box body 211 by the second driving source 271, so that the protective cover 212 is opened or covered on the box body 211, so that no manual operation is required, so as to improve the automation performance of the drill rod storage tooling 200, thereby saving manpower. Of course, the clamping member 272 can also be rotatably connected to the box body 211 through a hinge mechanism.

In the process of the protective cover 212 rotating relative to the box body 211, the provision of the first connection protrusion 211a and the second connection protrusion 212a can avoid the interference between the protective cover 212 and the box body 211 and limit the rotation range of the protective cover 212.

[0035] Optionally, in the width direction of the accommodating cavity, one end of the clamping member 272 may extend to the middle area of ​​the protective cover 212, thereby increasing the connection area between the clamping member 272 and the protective cover 212 to enhance the connection firmness therebetween.
