Description

Technical Field

[0001] The utility model belongs to the technical field of core tubes, in particular to a side sampling metal core tube. Background Art

[0002] The side-sampling metal core barrel is a specialized device for rock drilling. Its characteristic is that the core barrel body is equipped with a rotating door side outlet, which facilitates direct observation and rapid core extraction. This design not only effectively prevents the breakage of long columnar cores and improves the accuracy of rock quality evaluation, but also significantly reduces labor intensity and shortens coring time, thereby enhancing drilling efficiency.

[0003] At present, in actual application of existing core tubes, it is found that due to the drilling depth, multiple sections of core tubes need to be connected into one. However, the traditional threaded connection method has threads at both ends of the core tube, which is not only cumbersome and inconvenient to use, but also causes friction between the rock wall and the gap when moving up and down, causing damage to the already weak thread structure, affecting the subsequent use effect.

[0004] In order to solve the above problems, this application proposes a side sampling metal core tube. Utility Model Content

[0005] The purpose of the utility model is to provide a side sampling metal core tube, which solves the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model discloses a side sampling metal core tube, comprising: a core tube; a transfer tube with a bidirectional structure, located between adjacent core tubes, wherein both ends of the core tube are provided with a protruding outer ring, which is slidably installed inside the outer rings at the upper and lower ends of the transfer tube, so that the coating formed ensures that the inner and outer wall surfaces are smooth, and the structure of the connection area is stable, reducing the influence of external friction; the upper and lower ends of the transfer tube are also provided with a clamping plate, which is slidably docked in the positioning groove inside the convex ring, and plugs are provided on both sides of the end of the clamping plate for docking with the concave holes on both sides of the positioning groove, so as to replace the threaded structure and avoid the characteristic of its weak connection area.

[0008] Furthermore, circumferentially distributed positioning bolts are located at the upper and lower ends of the transfer tube, and positioning screw holes are provided inside the transfer tube for installing the positioning bolts.

[0009] Furthermore, a positioning guide hole aligned with the positioning screw hole is opened at the end of the clamping plate, which is used to penetrate the tapered rod mechanism at the end of the positioning bolt.

[0010] Furthermore, side holes perpendicularly intersecting the side holes are opened on both sides of the clamping plate for installing the plug.

[0011] Furthermore, a guide slope is provided at the end of the plug for automatically forming guidance and positioning during docking operation.

[0012] Furthermore, a protruding sliding block is provided at the lower end of the plug, which is slidably mounted inside the slideways on both sides of the clamping plate, and the slideways are located below the side holes.

[0013] Furthermore, one end of the slider is provided with a telescopic elastic column connected to an inner end surface of the slideway, which is used to drive the plug to automatically reset and release the fixation of the convex ring when the positioning bolt is removed.

[0014] The utility model has the following beneficial effects:

[0015] The utility model uses a convex ring instead of a thread, and can directly place adjacent core tubes together, and connect and fix them by the transfer tube and its components. This arrangement can not only greatly reduce the production difficulty of the core tube, but also make the connection operation simpler and more convenient, facilitate outdoor assembly and use, and improve the use effect of the core tube;

[0016] The utility model can form a fixed pipe body structure at the connection of adjacent core pipes through the cooperation of the convex ring, the clamping plate and the outer ring, which not only ensures the smooth structure inside and outside the pipe body, but also avoids the weak characteristics of the threaded structure, so as to resist external friction when moving up and down, ensure the stability of the connection structure, improve the operation quality, and prevent external rock chips from entering the gap and affecting the use quality of the connection area.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] See also Figure 1-5 As shown, the utility model is a side sampling metal core tube, comprising: a core tube 1; a bidirectional structured transfer tube 2, located between adjacent core tubes 1, with protruding outer rings 4 provided at both ends of the core tube 1, which are slidably mounted inside the outer rings 4 at the upper and lower ends of the transfer tube 2. The resulting covering ensures smooth inner and outer wall surfaces, while making the structure of the connection area stable and reducing the influence of external friction.

[0029] The upper and lower ends of the transfer tube 2 are further provided with clamping plates 5, which are slidably connected to the positioning groove 6 inside the convex ring 3. Plugs 11 are provided on both sides of the end of the clamping plate 5 for connecting with the concave holes on both sides of the positioning groove 6, replacing the threaded structure to avoid the characteristic of weak connection area.

[0030] This embodiment provides a core tube that can be quickly assembled. The traditional threaded structure can be replaced by the adapter tube 2 and its internal components in conjunction with the convex ring 3. This not only avoids the situation where the connection area is weak, but also facilitates outdoor assembly operations. While improving construction efficiency, the structure of the connection area is more stable to ensure the safety of the sampling operation.

[0031] Among them, the circumferentially distributed positioning bolts 7 are located at the upper and lower ends of the adapter tube 2. Positioning screw holes 8 are opened inside the adapter tube 2 for installing the positioning bolts 7. The positioning bolts 7 are a two-end structure, with a threaded structure at the tail end and a smooth rod structure at the other end, and a conical slope structure at its end.

[0032] Among them, a positioning guide hole 9 aligned with the positioning screw hole 8 is opened at the end of the clamping plate 5, which is used to penetrate the conical rod mechanism at the end of the positioning bolt 7. The conical structure is used to support the plug 11 so that it automatically slides outward.

[0033] Among them, side holes 10 perpendicularly intersecting the side holes 10 are opened on both sides of the card plate 5 for installing plugs 11 so that they are accommodated inside the card plate 5, making it convenient for the installation and use of the card plate 5.

[0034] A guide slope 13 is provided at the end of the plug 11 for automatically guiding and positioning during the docking operation to avoid misalignment and jamming.

[0035] The lower end of the plug 11 is provided with a protruding slider 12 , which is slidably installed inside the slideways 14 on both sides of the clamping plate 5 , and the slideways 14 are located below the side holes 10 .

[0036] One end of the slider 12 is provided with a telescopic spring 15 connected to an inner end surface of the slideway 14, which is used to drive the plug 11 to automatically reset and release the fixation of the convex ring 3 when the positioning bolt 7 is removed.

[0037] It is understandable that the present invention can quickly assemble adjacent core tubes 1 into one outdoors, and avoid the weak structure of traditional threads and susceptibility to rock debris intrusion, thereby ensuring the safety and convenience of sampling operations.

[0038] A specific application of the operation process of this embodiment is as follows: when in use, the transfer tube 2 is first placed between adjacent core tubes 1, and then the clamping plate 5 is inserted into the positioning groove 6 during docking, and then the positioning bolt 7 is screwed in, and the tapered rod at its end pushes the plug 11 to both sides, so that it is engaged with the concave holes on both sides of the positioning groove 6 to form a connection and fixation. In this way, adjacent core tubes 1 can be combined. Compared with the existing threaded connection method, it can avoid structural weakness and improve connection efficiency and convenience. It is convenient for outdoor connection and improves work efficiency. At the same time, it will not be affected by the erosion of rock chips, ensuring the stability of the connection structure and improving the stability of the sampling operation.
