[0002] With the development of submarine drilling equipment, submarine sampling drilling rigs have become an indispensable technical equipment for submarine resource exploration, submarine geological surveys, and marine scientific investigations. In order to meet the sampling depth requirements of submarine drilling rigs, the drilling rigs need to be equipped with a drill pipe storage room, where a large number of drill pipes are stored, and the drill pipe handling arm is used to store and retrieve the drill pipes in the storage room.
[0003] The existing drill rod warehouse has rubber partitions on both sides of the pipe storage slot, and uses the protrusions on the rubber partitions to separate and clamp the drill rods; or multiple spring partitions connected by rotating shafts are set on both sides of the pipe storage slot, and the spring partitions and the arc-shaped wear-resistant blocks connected thereto are used to divide the pipe storage slot at equal intervals and clamp the drill rods. Although the above two drill rod warehouses have realized the function of storing drill rods, the protrusions of the partitions will wear and deform under the frequent removal of drill rods, making it impossible to separate the drill rods at equal intervals, and thus causing the manipulator to be unable to accurately clamp the drill rods; and both of the above stores each drill rod in a fixed drill rod position, and can only rely on the extension of the manipulator to clamp the drill rod inside the pipe storage slot, which requires sacrificing space to avoid the movement of the manipulator when designing the drill rod warehouse, and the storage space cannot be fully utilized.

[0036] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the present disclosure is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present disclosure, and the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.
[0038] In each embodiment, for the convenience of description and not to limit the present disclosure, the term "connection" used in the patent specification and claims of the present disclosure is not limited to physical or mechanical connection, but may include electrical connection, whether direct or indirect. "Up", "down", "below", "left", "right", etc. are only used to indicate relative position relationship. When the absolute position of the described object changes, the relative position relationship also changes accordingly.
[0039] Figure 1 The following is a schematic diagram of the structure of a drill pipe storage device that automatically replenishes drill pipes. Figure 1 As shown, the drill rod storage device for automatically replenishing drill rods includes a main shaft 10, a pair of storage tube assemblies 20 and a pair of elastic members 30. The main shaft 10 is preferably a cylindrical structure and is generally fixed at a preset position in the vertical direction. The pair of storage tube assemblies 20 are respectively connected to the upper and lower parts of the main shaft 10, and the pair of elastic members 30 are arranged in the middle of the main shaft 10 and located between the pair of storage tube assemblies 20. When working, the upper and lower parts of the drill rod 40 are embedded in the storage tube assembly 20, and the pair of elastic members 30 push the drill rod 40 in the radial direction of the main shaft 10, so that multiple drill rods 40 can be fixed and stored.
[0040] Figure 2 is a schematic diagram of the structure of the storage tube assembly 20, Figure 3 FIG. 2 is a top view of the storage tube assembly 20. Figure 2 and Figure 3As shown, the pipe storage assembly 20 includes a mounting ring 21 and a pipe storage slot block 22. The mounting ring 21 is generally annular and sleeved on the main shaft 10. A plurality of pipe storage slot blocks 22 are connected to the mounting ring 21 and are distributed along the circumferential direction of the main shaft 10, and each pipe storage slot block 22 extends outward along the radial direction of the main shaft 10. In order to maximize the use of storage space, in this embodiment, the pipe storage slot block 22 has two or more specifications. As an example, the pipe storage slot block 22 has two specifications: one type of pipe storage slot block 22 can be embedded in three drill rods 40 at the same time along the radial direction of the drill rod 40, and the other type of pipe storage slot block 22 can be embedded in two drill rods 40 at the same time along the radial direction of the drill rod 40, and the two types of pipe storage slot blocks 22 are staggered. In this way, the smaller pipe storage slot blocks 22 can be configured in the area between the larger pipe storage slot blocks 22, so that the area between the larger pipe storage slot blocks 22 can be fully utilized to increase the storage capacity of the drill rod 40 storage device.
[0041] Figure 4 yes Figure 3 A partial enlarged view of the middle A. Figure 3 and Figure 4 As shown, as an example, the depth of the pipe storage slot 221 of the pipe storage slot block 22 is different from the depth of the pipe storage slot 221 of the adjacent pipe storage slot block 22, which is used to accommodate different numbers of drill rods 40. Specifically, the pipe storage assembly 20 includes pipe storage slots 221 with a first depth and pipe storage slots 221 with a second depth that are staggered in the circumferential direction, and the first depth is different from the second depth. In this embodiment, the first depth is larger, and three drill rods 40 can be embedded at the same time; the second depth is smaller, and two drill rods 40 can be embedded at the same time. Those skilled in the art understand that the number of pipe storage slot blocks 22 with different depth specifications can be set according to actual needs and space size, and at the same time, the number of drill rods 40 embedded in the first depth and the second depth can also be set according to actual needs and space size, and the present application does not limit this.
[0042] Since the length of the pipe storage slot block 22 with the first depth is longer, the circumferential space between two adjacent pipe storage slot blocks 22 with the first depth specification is larger. In order to make more rational use of the space, a pipe storage slot block 22 with a smaller second depth specification is arranged between two adjacent pipe storage slot blocks 22 with the first depth specification, so that the space of the pipe storage assembly 20 can be fully utilized and the number of stored drill rods 40 can be increased without hindering the storage and access of the drill rods 40.
[0043] Figure 5 2 is a schematic diagram of the structure of the storage pipe tank block 22 and the stopper assembly 23. Figure 5As shown, the pipe storage slot block 22 and the stopper assembly 23 are combined together to form a storage space that can be embedded and clamped with the drill rod 40. The pipe storage slot block 22 is used to clamp the drill rod 40, and the stopper assembly 23 is used to stop the drill rod 40, which can not only meet the requirements of the drill rod 40 being able to move into or out of the pipe storage slot block 22, but also can stop the drill rod 40 from moving out of the pipe storage slot block 22 abnormally.
[0044] Figure 6 2 is a schematic diagram of the structure of the storage tank block 22. Figure 5 and Figure 6 As shown, the pipe storage tank block 22 is generally a block structure, one end of which is connected to the main shaft 10 through the mounting ring 21 along the radial direction of the main shaft 10, and the other end extends along the radial direction. The pipe storage tank block 22 includes a pipe storage tank 221 and a mounting groove 222. The pipe storage tank 221 is used to embed the pipe storage tank 221 of the drill rod 40, and the mounting groove 222 is used to install and fix the stopper assembly 23.
[0045] Specifically, the length direction of the pipe storage groove 221 generally extends along the radial direction of the main shaft 10, and the opening 223 is located at the outer end of the pipe storage groove 221 in the radial direction (the end away from the main shaft 10). Further, the width h1 of the pipe storage groove 221 corresponds to the outer diameter of the drill rod 40, and can be equivalent to the outer diameter of the drill rod 40, or slightly larger than the outer diameter of the drill rod 40, so that the drill rod 40 can be clamped. The width h2 of the opening 223 of the pipe storage groove 221 is slightly smaller than the outer diameter of the drill rod 40, so that the drill rod 40 is difficult to escape from the pipe storage groove 221 through the opening 223. The mounting groove 222 is provided on the surface of the pipe storage groove block 22, for example, it can be the upper side surface or the lower side surface, and the outer surface of the mounting groove 222 is open to facilitate the installation of the stopper assembly. In addition, the length direction of the mounting groove 222 extends along the radial direction, and the width increases in the direction away from the main shaft 10. The inner wall of the mounting groove 222 is also provided with a protrusion 2221 for abutting against the elastic sheet 231. In this embodiment, the pipe storage tank block 22 has two installation slots 222 , which are respectively disposed on both sides of the pipe storage tank 221 .
[0046] Figure 7 Schematic diagram of the structure of the block assembly 23. Figure 5 and Figure 7 As shown, the stopper assembly 23 includes an elastic sheet 231 and a stopper 232. The stopper 232 is used to stop the drill rod 40 to prevent the drill rod 40 from escaping from the pipe storage groove 221. The elastic sheet 231 is used to bend and deform to move the stopper 232 along the width direction of the opening 223.
[0047] Specifically, the elastic sheet 231 is made of elastic material, preferably carbon fiber material. One end of the elastic sheet 231 is mounted on the tube storage slot block 22, and the other end extends to the opening 223 of the tube storage slot 221 in the radial direction. In addition, the middle of the elastic sheet 231 contacts the protrusion 2221 of the inner wall of the mounting slot 222, and the outer end has a certain gap with the inner wall of the mounting slot 222 in the width direction, so that the elastic sheet 231 can swing in the mounting slot 222. The stopper 232 is connected to the end of the elastic sheet 231 and protrudes toward the middle of the tube storage slot 221. In this way, the stoppers 232 of a pair of the stopper assemblies 23 on both sides of the tube storage slot 221 extend relative to each other, so that the width of the opening 223h2 of the tube storage slot 221 is smaller than the width h1 of the tube storage slot 221. In order to facilitate the removal of the drill rod 40, in this embodiment, the stopper 232 has an arc-shaped guide surface 2321 tangent to the inner wall of the pipe storage groove 221. The guide surface 2321 is substantially tangent to the inner wall of the pipe storage groove 221, so that the drill rod 40 can be guided to push the stopper 232 away and move out of the pipe storage groove 221.
[0048] During operation, the drill rod 40 pushes the stopper 232 when passing through the opening 223 , and the elastic sheet 231 is deformed to move the stopper 232 into or out of the pipe storage tank 221 .
[0049] Figure 8 30 is a schematic diagram of the structure of the elastic member 30. Figure 8 As shown, the support sheet 32 is made of elastic material, preferably carbon fiber material. In this embodiment, the elastic member 30 is connected to the main shaft 10 and extends toward the pipe storage groove 221, and is used to abut the drill rod 40 when the drill rod 40 is embedded in the pipe storage groove 221, and push the drill rod 40 toward the opening 223 of the pipe storage groove 221. Specifically, the elastic member 30 includes a mounting member 31 and a plurality of support sheets 32. The mounting member 31 is generally annular and sleeved on the main shaft 10. The plurality of support sheets 32 are distributed around the circumferential direction of the main shaft 10, one end of which is connected to the mounting member 31, and the other end of which extends along the length direction and radial direction of the main shaft 10 at the same time, forming a tapered structure spread out along the length direction of the main shaft 10. The end of each support sheet 32 corresponds to a pipe storage groove 221, and is used to abut the drill rod 40 toward the opening 223 when the drill rod 40 is installed in the pipe storage groove 221.
[0050] During operation, the mechanical arm clamps the drill rod 40 to push the stopper 232, pushes the stopper 232 to move to both sides of the opening 223, and puts the drill rod 40 into the pipe storage slot 221 of the pipe storage slot block 22. Since the width direction of the pipe storage slot 221 is equivalent to the outer diameter of the drill rod 40, multiple drill rods 40 are arranged in the radial direction in the pipe storage slot 221, and the length direction is generally parallel to the main shaft 10. And the innermost drill rod 40 (i.e., the drill rod 40 close to the main shaft 10) pushes the drill rod 40 toward the direction of the opening 223 under the elastic force of the support sheet 32. When the drill rod 40 needs to be obtained, the mechanical arm clamps the drill rod 40, and the drill rod 40 pushes the stopper 232 to move the drill rod 40 out of the pipe storage slot 221 from the opening 223. After the outermost drill rod 40 is moved out, the inner drill rod 40 moves toward the direction of the opening 223 under the action of the support sheet 32 to fill the position of the removed drill rod 40. In this way, the robot arm can still obtain the drill rod 40 at the original position next time, without the need to control the robot arm to adjust the position for obtaining the drill rod 40 .
[0051] The drill rod storage device for automatically replenishing drill rods is provided with a pipe storage slot block 22 on the main shaft 10, and the pipe storage slot block 22 is provided with a pipe storage slot 221 with an opening 223. The drill rod 40 can be stored in the pipe storage slot 221 in a radial direction, and the drill rod 40 is pushed toward the opening 223 of the pipe storage slot 221 by the elastic member 30 abutting against the drill rod 40. After the drill rod 40 closest to the opening 223 is taken away, the elastic member 30 can sequentially push the inner drill rod 40 to the position closest to the opening 223 again, so that the subsequent mechanical arm can still access the drill rod 40 at the original position again, without adjusting the access position of the mechanical arm.
