Detailed implementation manners

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Please refer to Figure 1 and Figure 2 , and now the core clamping device provided by the present invention will be described. The core clamping device includes a base 10 and a sliding clamping assembly. Among them, the top of the base 10 has a horizontally arranged slide rail. There are at least two sliding clamping assemblies, and each sliding clamping assembly is arranged at intervals along the length direction of the slide rail. Each sliding clamping assembly includes a sliding seat 21, a first roller 22, a second roller 23 and a power structure 24. The sliding seat 21 is slidably arranged on the slide rail. There are two first rollers 22, and both of the two first rollers 22 are rotatably arranged on the sliding seat 21 and are arranged at intervals in a horizontal direction perpendicular to the length direction of the slide rail, and a mounting space for the core sample 30 to be placed is formed between the two first rollers 22. The second roller 23 is located above the two first rollers 22. The power structure 24 is arranged on the sliding seat 21 and can drive the first roller 22 to move and abut against the core sample 30 located in the mounting space, so that the second roller 23 and the two first rollers 22 jointly clamp and fix the core sample 30.

[0022] Compared with the prior art, the core clamping device provided in this embodiment has multiple sliding clamping components that can slide on the slide rail, and the spacing distance can be adjusted, so as to adapt to core samples 30 of different lengths, with strong adaptability. The two first rollers 22 provided on each sliding clamping component can ensure the loading of the core sample 30, and the power structure 24 can drive the second roller 23 to move, so that the second roller 23 and the two first rollers 22 jointly clamp and fix the core sample 30. The clamping work is convenient, which can improve the working efficiency of fixing the core sample 30, and further improve the working efficiency of testing the core sample 30, with strong practicability.

[0023] In some embodiments, the above-mentioned slide seat 21 can adopt a structure as Figures 1 to 2 shown. Refer to Figures 1 to 2 , the slide seat 21 includes a horizontal portion 211 and a vertical portion 212. The horizontal portion 211 is slidably arranged on the slide rail, and each first roller 22 is rotatably arranged on the horizontal portion 211. The vertical portion 212 is arranged at one end of the horizontal portion 211 along the horizontal direction perpendicular to the length direction of the slide rail, and the bottom end of the vertical portion 212 is fixedly connected to the horizontal portion 211. The horizontal portion 211 can ensure the installation of the first roller 22. The vertical portion 212 is connected to the horizontal portion 211, which can ensure that the vertical portion 212 can move synchronously with the horizontal portion 211, so as to ensure adaptation to core samples 30 of different lengths, with strong practicability.

[0024] The horizontal portion 211 can be in the shape of a rectangular plate body. Preferably, a shaft seat for the first roller 22 to be rotatably connected can be provided on the horizontal portion 211

[0025] In some embodiments, the above-mentioned slide seat 21 can adopt a structure as Figures 1 to 2 shown. Refer to Figures 1 to 2 , the rotation axis of each first roller 22 is arranged along the horizontal direction perpendicular to the length direction of the slide rail. The axis of the first roller 22 is perpendicular to the length direction of the slide rail, which can ensure that the first roller 22 makes rolling contact with the core sample 30, that is, it can move and adjust the core sample 30 along the axis direction of the core sample 30 in the state of clamping and fixing the core sample 30, so as to ensure adaptation to the testing equipment and prevent the clamping and fixing assembly 20 from interfering with the testing equipment, with strong practicability.

[0026] In some embodiments, the above-mentioned slide seat 21 can adopt a structure as Figures 1 to 2 shown. Refer to Figures 1 to 2 , the slide rail includes at least two guide rods, and the guide rods are parallel and spaced apart. The multiple guide rods can ensure the stable sliding of the horizontal portion 211. Among them, the horizontal portion 211 is provided with slide holes for the guide rods to pass through.

[0027] In some embodiments, the above-mentioned slide seat 21 can adopt a structure as Figures 1 to 2 shown. Refer toFigures 1 to 2 The power structure 24 includes a flipping rod 241 and a telescopic structure 242. The flipping rod 241 is hinged to the top end of the vertical part 212, and the hinge axis is arranged along the length direction of the slide rail. The flipping rod 241 has a first end and a second end of the flipping rod 241. The hinge point between the flipping rod 241 and the vertical part 212 is located between the first end and the second end of the flipping rod 241. The first end of the flipping rod 241 is for the second roller 23 to be rotatably connected. The telescopic structure 242 has a fixed end and a telescopic end. The fixed end of the telescopic structure 242 is hinged to the vertical part 212, and the telescopic end of the telescopic structure 242 is hinged to the second end of the flipping rod 241. The telescopic structure 242 can drive the flipping rod 241 to pitch and rotate. By the telescoping of the telescopic structure 242, the pitching rotation of the flipping rod 241 is realized, which can ensure the contact or separation of the second roller 23 from the core sample 30. Its structure is simple, the clamping process is time-saving and labor-saving, and it has strong practicability.

[0028] In this embodiment, the telescopic structure 242 can be a cylinder, which is connected to an external air pump.

[0029] A fixed shaft 2411 for the second roller 23 to be rotatably connected is provided at the first end of the flipping rod 241. In some embodiments, reference can be made to Figure 3 , when the core sample 30 is clamped by the first roller 22 and the second roller 23, the stability of the core sample in its axial direction is poor. Therefore, each power structure 24 further includes a locking member 243 capable of locking the second roller 23. The locking member 243 includes a screw 2431 threadedly connected to a threaded hole provided on the fixed shaft 2411. A turntable 2432 is provided at one end of the screw 2431 located outside the threaded hole. A wear-resistant ring 2433 is provided on the side of the turntable 2432 close to the threaded hole, and a gripping portion 2434 that is convenient for hand gripping, such as a prism block, is provided on the side of the turntable 2432 away from the threaded hole.

[0030] After the core is clamped, in order to avoid the circumferential movement of the core 30, the turntable 2432 can be driven to rotate through the gripping portion 2434, so that the wear-resistant ring 2433 approaches and abuts against the second roller 23 to prevent the second roller 23 from rotating, thereby ensuring the stability of the core 30. Conversely, the rotational locking of the second roller 23 can be released.

[0031] In some embodiments, the above-mentioned slide seat 21 can adopt the structure as Figures 1 to 2 shown. Refer to Figures 1 to 2, the rotation axis of the second roller 23 is arranged along the length direction of the flipping rod 241, and the axis of the second roller 23 is perpendicular to the length direction of the slide rail, which can ensure that the second roller 23 is in rolling contact with the core sample 30. That is, when the core sample 30 is clamped and fixed, the core sample 30 can be moved and adjusted along the axis direction of the core sample 30 to adapt to the test equipment and prevent the clamping and fixing assembly 20 from interfering with the test equipment, which has strong practicability.

[0032] It should be noted that the structure of the second roller 23 can be the same as that of the first roller 22, and the outer peripheral surfaces of the second roller 23 and the first roller 22 can be covered with rubber layers.

[0033] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
