Description

Technical Field

[0001] This utility model belongs to the technical field of geotechnical exploration strength testing equipment, and in particular relates to a geological geotechnical exploration strength testing device. Background Technology

[0002] From an engineering and construction perspective, "rock and soil" is a general term for any type of rock and soil that makes up the Earth's crust. Rock and soil can be further subdivided into five categories: hard, medium-hard, weakly connected, loosely connected, and those with special composition, structure, state, and properties. Current geological exploration processes generally require strength testing of rock and soil. A search revealed a patent application with application number 202120835879.7, which discloses a geological rock and soil exploration strength testing device. The device includes a base, with support plates fixedly connected to both sides of the top of the base. A top plate is fixedly connected to the top of the two support plates, and a hydraulic cylinder is fixedly connected to the top of the top plate. The bottom end of the hydraulic cylinder's output shaft extends to the bottom of the top plate and is fixedly connected to a pressing plate. A placement tube is fixedly connected to the top of the base, and transparent glass is embedded in the inner wall of the front side of the placement tube. An elastic pad is magnetically fixed to the bottom of the pressing plate, and a mounting plate is adhesively fixed to the bottom of the elastic pad. A pusher block is fixedly connected to the top of the mounting plate.

[0003] However, during actual use, the applicant found that during the pressurization of soil and rock, part of the force on the mounting plate was transmitted to the pressure measuring instrument through the push block, and another part was transmitted to the elastic pad, which made the data of soil and rock strength test inaccurate. In addition, when the soil and rock inside the placement tube were tightly blocked by the spring-driven push plate to push the soil and rock out of the placement tube, the spring force was not enough to drive the push plate to push the soil and rock out of the placement tube. In view of this, we propose a geological soil and rock exploration strength test device. Summary of the Invention

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A geological and soil exploration strength testing device includes a base 1. A top seat 3 is fixedly connected to the top of the base 1 via a support column 2. A hydraulic cylinder 4 is fixedly mounted on the top of the top seat 3. A controller 5 is fixedly mounted on the top of the base 1 in front of the hydraulic cylinder 4. The controller 5 is electrically connected to an external power supply via a wire. The telescopic end of the hydraulic cylinder 4 passes through the top of the top seat 3 and is fixedly connected to a lifting plate 6. Guide columns 61 are fixedly installed on the top of the lifting plates 6 on both the front and rear sides of the hydraulic cylinder 4. The upper ends of the guide columns 61 movably pass through the top seat 3. A base body 7 is fixedly connected to the bottom of the lifting plate 6. A device is fixedly installed inside the base body 7. A pressure measuring instrument 12 is provided. A transparent observation window is provided on the base 7 on the front side of the pressure measuring instrument 12 to facilitate personnel to observe the pressure measurement reading on the pressure measuring instrument 12. The hydraulic cylinder 4 and the pressure measuring instrument 12 are electrically connected to the controller 5 through wires. A soil and rock pressure plate 8 is movably connected to the bottom of the base 7. A push block 81 is fixedly installed at the center of the top of the soil and rock pressure plate 8. The upper end of the push block 81 extends into the interior of the base 7 and is movably connected to the measuring end at the bottom of the pressure measuring instrument 12. Guide rods 82 are symmetrically fixedly installed on the top of the soil and rock pressure plate 8. The upper ends of the two guide rods 82 respectively movably pass through... The base 7 has symmetrically arranged guide ears 71 on both sides and fixed limiting parts. During the process of pressurizing the soil and rock through the soil and rock pressure plate 8, the soil and rock pressure plate 8 can drive the push block 81 to squeeze the measuring end of the pressure measuring instrument 12, so that the pressure measuring instrument 12 can realize the accurate test measurement of soil and rock strength. The top of the base 1 below the soil and rock pressure plate 8 is fixedly connected to the soil and rock placement frame 10. The interior of the base 1 is slidably connected to the U-shaped movable seat 11, and the top of the U-shaped movable seat 11 extends into the soil and rock placement frame 10. When conducting geological soil and rock strength tests, the soil and rock to be tested can be placed in the frame. The top of the convex movable seat 11 placed in the soil and rock placement frame 10 is then driven by the hydraulic cylinder 4 driven by the controller 5 to move the lifting plate 6 downward. The downward movement of the lifting plate 6 can drive the lifting plate 6 and the soil and rock pressure plate 8 to move downward together. At this time, the soil and rock inside the soil and rock placement frame 10 can be squeezed by the soil and rock pressure plate 8. During this process, the soil and rock pressure plate 8 drives the push block 81 to squeeze the measuring end of the pressure measuring instrument 12. The soil and rock strength can be measured by the pressure measuring instrument 12, and the measurement reading on the pressure measuring instrument 12 can be viewed through the transparent observation window on the seat body 7.

[0022] The top of the lifting plate 6 has symmetrically arranged hanging slots 62 on both sides. L-shaped pull rods 9 are symmetrically and movably connected to the base 1 on both sides of the soil and rock placement frame 10. The bent part at the upper end of the L-shaped pull rod 9 is located directly above the hanging slot 62. The lower end of the L-shaped pull rod 9 extends into the base 1 and is fixedly connected to the U-shaped movable seat 11. During the upward movement of the lifting plate 6, the L-shaped pull rod 9 can be pulled upward, and the L-shaped pull rod 9 can drive the U-shaped movable seat 11 upward, smoothly bringing out the pressurized and crushed soil and rock inside the soil and rock placement frame 10 without the need for manual removal of the crushed soil. The block is pried out from inside the soil and rock placement frame 10, which is more convenient. After the soil and rock strength test is completed, the hydraulic cylinder 4 can be reversed to drive the lifting plate 6 to move upward. During this process, the upper end of the L-shaped tie rod 9 can be inserted into the hanging groove 62, and the L-shaped tie rod 9 can pull the convex movable seat 11 upward, so that the soil and rock inside the soil and rock placement frame 10 can be brought out through the convex movable seat 11. When the top of the convex movable seat 11 is flush with the top of the soil and rock placement frame 10, the hydraulic cylinder 4 is stopped, and then all the soil and rock can be cleaned off the convex movable seat 11.

[0023] Working Principle: During geological and soil strength testing, the soil and rock to be tested can be placed on top of the U-shaped movable seat 11 in the soil and rock placement frame 10. Then, the controller 5 drives the hydraulic cylinder 4 in a forward direction to move the lifting plate 6 downwards. This downward movement of the lifting plate 6 and the soil and rock pressure plate 8 moves downwards together. At this time, the soil and rock inside the soil and rock placement frame 10 are compressed by the soil and rock pressure plate 8. During this process, the soil and rock pressure plate 8 drives the push block 81 to compress the measuring end of the pressure measuring instrument 12. The soil and rock strength can be measured by the pressure measuring instrument 12. The measurement reading on the pressure measuring instrument 12 can be viewed through the transparent observation window on the seat 7. After the soil and rock strength test is completed, the hydraulic cylinder 4 can be reversed to move the lifting plate 6 upward. During this process, the upper end of the L-shaped tie rod 9 can be inserted into the hanging groove 62, and the L-shaped tie rod 9 can pull the U-shaped movable seat 11 upward, so that the soil and rock inside the soil and rock placement frame 10 can be brought out through the U-shaped movable seat 11. When the top of the U-shaped movable seat 11 is flush with the top of the soil and rock placement frame 10, the hydraulic cylinder 4 is stopped, and then all the soil and rock can be cleaned off the U-shaped movable seat 11.
