Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and more specifically, to a core cutting auxiliary device. Background Technology

[0002] In geological exploration, drilling is often used to extract columnar rock cores from the strata. These cores are then cut in half using a core splitter to obtain samples for analysis. When cutting columnar rock cores with a core splitter, the core is usually held in place by hand before the machine is used. Furthermore, existing technologies also include devices that hold the core in place before cutting.

[0003] Patent document CN222450894U discloses a rock core auxiliary cutting device. This utility model includes a support platform and an auxiliary cutting component. The auxiliary cutting component is a cylindrical structure, vertically mounted on a fixed frame, meaning its height is perpendicular to the ground. An opening is provided through the auxiliary cutting component to accommodate a cutting tool. In use, the cutting tool of the cutting machine is placed in the opening beforehand. The cutting machine is started, and the rock core is inserted through the opening at the top of the cylindrical auxiliary cutting component. Under gravity, the rock core falls into the auxiliary cutting component and is cut in two during its descent. The entire process stably cuts the rock core while allowing it to fall freely after being placed in the auxiliary cutting component, eliminating the need for auxiliary tools to continuously push the rock core into the component. This reduces safety hazards and is convenient to use, requiring only the continuous insertion of rock cores into the auxiliary cutting component, thus improving work efficiency.

[0004] However, in the use of existing cutting devices, if the outer diameter of the core is smaller than the inner diameter of the auxiliary cutting element, the core is prone to deflection after contacting the cutting blade when it falls from the auxiliary cutting element. This causes the cutting surface of the core to tilt, which may result in an abnormal exposure area of ​​a certain mineral layer, affecting the accurate judgment of the mineral composition of the strata and thus affecting the subsequent analysis of the core. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a core cutting auxiliary device that can center the core as much as possible when it enters the auxiliary cutting component, thereby reducing the probability of the core cutting surface tilting.

[0006] A core cutting auxiliary device includes a frame with a vertical plate fixedly connected to it. A collar is fixedly connected to the side wall of the vertical plate, and an auxiliary cutting component is slidably and detachably mounted on the collar. A through groove is formed on the vertical plate, and a positioning mechanism is installed in the through groove. The positioning mechanism includes two movable frames that slide in the through groove. A connecting frame is fixedly connected to one end of each movable frame. The two connecting frames are arc-shaped on the side closest to each other, and positioning posts are fixedly connected to both ends. An installation ring is fixedly connected to the side wall of the vertical plate, and a screw is rotatably connected to the installation ring. The screw has two external threads with opposite patterns, and the screw passes through and is screwed to the movable frame.

[0007] Furthermore, the auxiliary cutting component is provided with a cutting groove.

[0008] Furthermore, the two movable frames are located on different external threads.

[0009] Furthermore, the center point of the rectangle formed by connecting the centers of the four positioning posts is located on the extension line of the center line of the auxiliary cutting component.

[0010] Furthermore, a handle is fixedly connected to one end of the screw.

[0011] Furthermore, a ball head is fixedly connected to the upper end of the positioning post.

[0012] Furthermore, the surfaces of both the ball head and the positioning post are smoothed.

[0013] Furthermore, a bolt is threaded through and screwed onto the collar, and the surface of the auxiliary cutting component is provided with a threaded groove adapted to the bolt.

[0014] Furthermore, a collection box is fixedly connected to one side of the vehicle frame, and rubber pads are fixedly connected to both the inner wall of the collection box and the side wall of the vehicle frame.

[0015] Furthermore, the frame is equipped with casters at the bottom and handrails are fixed to the frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, by rotating the screw, the two moving frames are brought closer or further apart, so that the four positioning posts can fit and conform to the surface of the core to be cut. Before the core enters the auxiliary cutting component, it first passes between the four positioning posts of the positioning mechanism. After the core enters the auxiliary cutting component, it can be centered as much as possible, thereby reducing the probability of the core cutting surface tilting and avoiding affecting the subsequent analysis of the core.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0026] like Figure 1-4As shown, a core cutting auxiliary device includes a frame 1, a vertical plate 2 fixedly connected to the upper end face of the frame 1, a collar 3 fixedly connected to the side wall of the vertical plate 2, an auxiliary cutting component 4 slidably and detachably mounted on the collar 3, the auxiliary cutting component 4 being a hollow cylindrical shape, a cutting machine 5 fixedly mounted on the vertical plate 2, and a cutting groove 41 for a cutting blade to pass through the auxiliary cutting component 4, the cutting groove 41 communicating with the upper end face of the auxiliary cutting component 4, thus not affecting the disassembly of the auxiliary cutting component 4; a through groove 21 is provided on the vertical plate 2, a positioning mechanism 6 is installed in the through groove 21, the positioning mechanism 6 is located directly above the auxiliary cutting component 4, and the positioning mechanism 6 includes components that slide within the through groove 21. The system includes two movable frames 61. A connecting frame 62 is fixedly connected to one end of each movable frame 61 near the auxiliary cutting component 4. The two connecting frames 62 are arc-shaped on their closest side, with positioning posts 63 fixedly connected to both ends of the arc. A mounting ring 64 is fixedly connected to the side of the upright plate 2 away from the auxiliary cutting component 4. A screw 65 is rotatably connected to the mounting ring 64. The screw 65 has symmetrically arranged external threads with opposite patterns. The screw 65 passes through and is threaded to the two movable frames 61, which are located on different external threads. The center point of the rectangle formed by the four positioning posts 63 is located on the extension line of the centerline of the auxiliary cutting component 4. By rotating the screw 65, the two movable frames 61 can move closer or further apart, allowing the four positioning posts 63 to fit snugly against the surface of the core to be cut. Before entering the auxiliary cutting component 4, the core first passes between the four positioning posts 63 of the positioning mechanism 6. After entering the auxiliary cutting component 4, the core is centered as much as possible, reducing the probability of a tilted core cutting surface and avoiding interference with subsequent core analysis.

[0027] like Figure 1-4 As shown, a handle 66 is fixedly connected to one end of the screw 65, which facilitates the rotation of the screw 65 by the operator. A ball head 67 is fixedly connected to the upper end of the positioning post 63. The surfaces of the ball head 67 and the positioning post 63 are both smooth. After one operator places the rock core to be cut above the four positioning posts 63, another operator rotates the screw 65 to move the two moving frames 61 away from each other. During this process, the periphery of the bottom of the rock core contacts the ball head 67 and descends along its surface until it can pass through the four positioning posts 63. The ball head 67 makes it easier for the operator to adjust the positioning mechanism 6 according to the outer diameter of the rock core.

[0028] like Figure 1-4 As shown, a bolt 7 is threaded through and connected to the collar 3. The outer surface of the auxiliary cutting component 4 is provided with a threaded groove 42 that is adapted to the bolt 7. The position of the auxiliary cutting component 4 can be fixed by the bolt 7 in conjunction with the collar 3 and the threaded groove 42, thereby realizing the sliding and detachable nature of the auxiliary cutting component 4, which facilitates the replacement of the auxiliary cutting component 4.

[0029] like Figure 1-4As shown, a collection box 8 is fixedly connected to one side of the frame 1. The collection box 8 is located at the bottom of the auxiliary cutting component 4 and is used to collect the rock core after cutting. Rubber pads 9 are fixedly connected to the inner wall of the collection box 8 and the side wall of the frame 1. The rubber pads 9 help to protect the rock core and prevent it from being damaged by bumps.

[0030] like Figure 1-4 As shown, a caster wheel 10 is installed at the bottom of the frame 1. In this embodiment, the caster wheel 10 is a caster wheel with a brake. A handrail 11 is also fixedly connected to the frame 1. The handrail 11 is set in conjunction with the caster wheel 10 to facilitate the use of the mobile device.

[0031] The working principle of the core-assisted cutting device in this embodiment is as follows: After one worker places the core to be cut above the four positioning posts 63, another worker rotates the screw 65 to move the two moving frames 61 away from each other. During this process, the periphery of the bottom of the core contacts the ball head 67 and descends along its surface until it can pass through the four positioning posts 63. This allows the four positioning posts 63 to fit and conform to the surface of the core to be cut. Before entering the auxiliary cutting component 4, the core first passes between the four positioning posts 63 of the positioning mechanism 6. After the core enters the auxiliary cutting component 4, it can be centered as much as possible. After the bottom of the core contacts the cutting blade, its upper end has not yet completely passed through the positioning mechanism 6, thereby reducing the probability of the core cutting surface tilting and avoiding affecting the subsequent analysis of the core.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
