Description

Technical Field

[0001] This utility model relates to the field of soil and rock compaction technology, and in particular to a specimen compaction device. Background Technology

[0002] Soil and rock compaction refers to the engineering process of rearranging soil or rock fragments by applying external force to reduce pore volume, thereby improving their density and mechanical properties.

[0003] Before compaction, the soil and rock specimens are crushed by a crushing device. The crushed soil and rock are then placed in a compaction mold and compacted by a compaction plate. However, different types of soil and rock require different sizes of compaction molds. When compacting different types of soil and rock, different compaction molds and compaction plates need to be changed manually. This is not only cumbersome, requiring manual tightening of multiple bolts to change the compaction plate, but also wastes too much time and is not convenient for high-efficiency use. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A specimen compaction device includes a base plate 1, on which four equidistant fixed columns 2 are fixedly installed. A top plate 3 is fixedly installed on the upper end of the four fixed columns 2. A hydraulic rod 4 is fixedly installed at the bottom end of the top plate 3. By extending and retracting the hydraulic rod 4, a compaction plate 8 is driven to compact the soil and rock inside the compaction mold 17. A limiting sleeve 6 is sleeved on the outer wall of the hydraulic rod 4. The compaction plate 8 is fixedly installed at the bottom end of the limiting sleeve 6. Four first limiting holes 5 are correspondingly opened on the hydraulic rod 4 and the limiting sleeve 6, which are evenly spaced around the circumference. A first fixing pin 7 is provided in each of the four first limiting holes 5. By placing the first fixing pin 7 in the first limiting hole 5, the limiting sleeve 6 is fixed on the outer wall of the hydraulic rod 4, which facilitates the replacement and disassembly of the compaction plate 8.

[0023] Four equidistant support legs 9 are fixedly installed on the base plate 1, and an operating frame 11 is fixedly installed on the four support legs 9. A through groove is opened at the bottom of the operating frame 11, and a placement platform 18 is movably arranged in the through groove. An electric telescopic rod 10 is fixedly installed at the bottom of the placement platform 18. Four corresponding limit blocks 19 are fixedly installed on both the operating frame 11 and the placement platform 18, and a second limit hole is opened on the limit block 19. A second fixing pin 20 is movably arranged in the second limit hole. The second fixing pin 20 is placed into the second limit hole to fix the placement platform 18 on the operating frame 11. When the rock and soil are compacted, the placement platform 18 moves down, and the bottom of the electric telescopic rod 10 is fixedly installed on the base plate 1.

[0024] A compaction mold 17 is fixedly installed on the placement platform 18. Four sets of telescopic guide rods 21 are fixedly installed inside the operation frame 11, and each of the four sets of telescopic guide rods 21 has a limiting plate 15 fixedly installed at its end to limit the compaction mold 17.

[0025] Four equally spaced lead screws 12 are rotatably mounted on the operating frame 11, and threaded sleeves 14 are threadedly fitted onto the outer walls of the four lead screws 12. The other end of the threaded sleeves 14 is fixedly installed on the outer wall of the limiting plate 15.

[0026] A rotating handle 13 is fixedly installed at the end of the lead screw 12. A telescopic hose 16 is fixedly installed between the limit plate 15 and the operating frame 11. The lead screw 12 is set inside the telescopic hose 16 to prevent rock and soil debris in the compaction mold 17 from falling onto the outer wall of the lead screw 12 and to prevent it from affecting the fit between the lead screw 12 and the threaded sleeve 14.

[0027] It should be noted that the specific model and specifications of the electric telescopic pole 10 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0028] The functional principle of this utility model can be explained through the following operation methods:

[0029] In use, the hydraulic rod 4 extends and retracts to move the compaction plate 8 toward the compaction mold 17 to compact the soil and rock inside the compaction mold 17. When it is necessary to replace the compaction plate 8 with a different size, the four first fixing pins 7 are removed from the four first limiting holes 5 respectively to release the limitation of the limiting sleeve 6, which facilitates the quick replacement and installation of the compaction plate 8.

[0030] By extending and retracting the electric telescopic rod 10, the placement platform 18 moves the compaction mold 17 downward, facilitating the replacement of compaction molds 17 of different sizes. After the compaction mold 17 is replaced, the electric telescopic rod 10 extends and retracts, causing the compaction mold 17 to move back into the operating frame 11. The second fixing pin 20 slides the mold into the two limit blocks 19, limiting and fixing the placement platform 18. With the rotation of the rotating handle 13, the threaded sleeve 14 moves axially toward the compaction mold 17 along the screw 12. The position of the compaction mold 17 is adjusted by the limit plate 15, placing the compaction mold 17 directly below the compaction plate 8 and limiting and fixing the compaction mold 17.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
