[0028] Here, it should also be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less relevant to the present utility model are omitted.
[0029] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
[0030] Please refer to Figures 1 to 3 As shown, the present utility model provides a device for drawing the bus of a core in a directional drilling, which includes a bracket 1, a floating fixing part, a marker pen 5 and a slide rail 6.
[0031] Among them, the bracket 1 is an arc-shaped structure, including connecting ends (not marked in the figure) symmetrically arranged at both radial ends of the bracket 1, a scale 7 arranged along the arc length path of the bracket 1, and a hollow chute 8 arranged along the arc length path of the bracket 1.
[0032] In some implementation modes, the distance between the symmetrically arranged connecting ends is set to the diameter length of the core 10. Thus, the connecting ends can be enclosed (fitted) and connected with the ends at both ends of the semi-circular core extraction sleeve 9.
[0033] Please refer to FIG. 2. The hollow chute 8 is arranged in the middle of the bracket 1 and is an overall hollow arc-shaped structure for enabling the floating fixing part to slide to a predetermined scale 7 position.
[0034] The scale 7 is arranged at both axial ends of the bracket 1.
[0035] The floating fixing part is slidably connected with the bracket 1 along the arc length path of the bracket 1. Specifically, the floating marking part is slidably connected with the hollow chute 8 and slides to reach a predetermined scale 7 position.
[0036] The movable fixing part includes a fixing tray 2 abutting against the inner wall of the bracket 1, a fixing nut 3 arranged on one side of the outer wall of the bracket 1 and connected to the fixing tray 2, and a clamping bolt 4.
[0037] Please refer to Figure 2 and Figure 3 As shown, the fixing tray 2 includes an arc tray (not marked in the figure) and a hollow clamping part 11 arranged at the center of the arc tray.
[0038] The hollow clamping part 11 is a hollow concave structure, and the marker pen 5 is sleeved through the hollow clamping part 11.
[0039] A screw hole is arranged on the hollow clamping part 11; the screw hole is threadedly connected to the clamping bolt 4.
[0040] External threads are arranged on the outer wall of the hollow clamping part 11, and internal threads are arranged on the fixing nut 3 that are mutually matched with the external threads of the hollow clamping part 11. Thus, the fixing tray 2 is threadedly connected to the fixing nut 3.
[0041] The inner diameter of the hollow clamping part 11 is larger than the outer diameter of the marker pen 5.
[0042] By rotating the clamping bolt 4 inward, it abuts against the marker pen 5 to clamp and limit the marker pen 5. External thread structures are arranged on the clamping bolt 4 for threaded connection with the screw hole.
[0043] Based on the hollow concave structure of the hollow clamping part 11, the hollow clamping part 11 passes through the hollow sliding groove 8 and is mutually matched and connected with the internal threads of the fixing nut 3, thereby realizing the movable fixing of the movable fixing part and the marker pen 5 to the predetermined scale 7 position.
[0044] Please refer to Figure 2 and Figure 3 As shown, the slide rail 6 is arranged on the outer walls of the connecting ends at both ends of the bracket 1.
[0045] In some specific embodiments, the slide rail 6 is a vertically extending structure; when the connecting ends are mutually enclosed and connected to both ends of the core-taking casing 9, the slide rail 6 is tangent to the outer walls of both ends of the core-taking casing 9 to realize the limiting sliding of the bracket 1 along the core-taking casing 9.
[0046] In the working state, the connecting ends are mutually enclosed and connected to both ends of the semi-circular core-taking casing 9, and through the sliding of the slide rail 6, the bracket 1 axially slides along both ends of the core-taking casing 9, driving the marker pen 5 fixed on the bracket 1 to draw along the generatrix of the core 10.
[0047] The working principle of the device for drawing the bus line of the directional drilling core provided by the present utility model is as follows:
[0048] After the core 10 is cored by using three-layer casing, the orientation of the drilling hole is determined by an instrument, and a mark is drawn at the end of the core 10 to facilitate the later drawing of the bus line. After the core 10 is taken out, the innermost coring casing 9 is composed of two semi-circular parts, and only one piece of the coring casing 9 needs to be opened.
[0049] Place the device for drawing the bus line of the directional drilling core on both ends of the other piece of the coring casing 9, so that the connecting ends are enclosed and connected with both ends of the coring casing 9. Based on the limiting and sliding action of the slide rail 6, the connecting ends at both ends of the coring casing 9 and the connecting ends at both ends of the bracket 1 will not shift. Adjust the fixing nut 3 to make the floating fixing part slide along the hollow chute 8. After the tip of the marker pen 5 corresponds to the mark at the end of the core 10, adjust the fixing nut 3 again for limiting and fixing. Then rotate the clamping bolt 4 to fix the marker pen 5, so that the device for drawing the bus line of the directional drilling core will not shift during the movement (sliding) process. Move the slide rail 6 to make the bracket 1 slide axially along the coring casing 9, driving the marker pen 5 fixed on the bracket 1 to draw the bus line along the core 10.
[0050] In summary, the present utility model provides a device for drawing the bus line of the directional drilling core, which relates to the technical field of geological surveying and mapping. The device includes a bracket, a marker pen and a floating fixing part; the bracket is of an arc-shaped structure, and connecting ends are symmetrically arranged at both ends of the bracket; the marker pen is connected with the floating fixing part; the floating fixing part is slidably connected with the bracket along the arc length path of the bracket; in the working state, the connecting ends are enclosed and connected with both ends of the semi-circular coring casing and slide axially along the coring casing, driving the marker pen installed on the bracket to draw the bus line along the core. Under the action of the slide rail, the drawing of the bus line of one round trip of the core can be completed quickly and efficiently. Moreover, under the action of the slide rail, the fixing nut and the clamping bolt, the drawing of the bus line is more accurate, avoiding the deviation in the drawing process, and effectively overcoming the technical problems of easy deviation and low efficiency existing in the manual drawing in the prior art.
[0051] The above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model.
