Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a pressurizing device for detecting the mechanical properties of civil engineering materials. Background Art

[0002] Civil engineering is a general term for the science and technology of building various types of engineering facilities. It refers to the materials and equipment used and the technical activities such as survey, design, construction, maintenance, and repair carried out. It also refers to the objects of engineering construction, that is, various engineering facilities built on the ground or underground, on land or in water, which directly or indirectly serve human life, production, military, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, and protective projects. During the construction of civil engineering projects, it is necessary to test the mechanical properties of construction materials, which requires the use of pressurizing devices. Traditional pressurizing devices are relatively simple in function and do not have the function of protecting materials during the pressurization process. If the pressure is too high and the material is broken, it will cause material debris to fly everywhere, posing a safety hazard.

[0003] The prior art proposes a Chinese patent with publication number CN218239568U to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a pressurizing device for testing the mechanical properties of civil engineering materials, including a workbench, a concave frame fixedly connected to the top of the workbench, a drive box fixedly connected to the top of the inner cavity of the concave frame, a moving assembly provided in the inner cavity of the drive box, a push rod provided at the bottom of the moving assembly, and a push plate movably connected to the end of the push rod away from the moving assembly through a movable shaft, and a pressure block fixedly connected to the bottom of the push plate. The utility model can drive the push rod, push plate and pressure block to move downward by arranging a servo motor, a threaded rod and a threaded sleeve, so as to pressurize the material and then test its mechanical properties. At the same time, it can also drive the protective frame, the compression spring and the protective plate to move downward, so that the protective frame and the protective plate are always located around the material to protect the surrounding areas of the material and avoid the debris from flying around when the material is crushed. By arranging the above structure, the advantage of being able to protect the material during the pressurization process is achieved. However, the material is only manually overlapped on the pad before being pressurized, and the detection position where the material needs to bear the pressure cannot be accurately determined, which affects the detection accuracy. Utility Model Content

[0004] The purpose of the utility model is to provide a pressurizing device for testing the mechanical properties of civil engineering materials, so as to solve the problems raised in the above-mentioned background technology.

The laser generator is rotatably connected to the top of the electric lifting rod through a mounting seat. The mounting seat is used to adjust the irradiation angle of the laser generator. The positioning seat is slidably sleeved on the outer wall of the guide rail.

[0007] A calibration positioning point is provided on the upper surface of the pressure pad, a guide groove is provided on the upper surface of the pressure pad, a clamping slider is slidably connected to the inner wall of the guide groove, a slider bevel is provided on the top of the clamping slider, and a positioning groove is provided on the bottom of the inner wall of the slider bevel.

[0022] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] The present invention is further described in detail below with reference to the embodiments:

[0024] Example 1

[0025] like Figure 1-4As shown, the utility model provides a pressurizing device for testing the mechanical properties of civil engineering materials, including a workbench 1, a pressure block 2, a pressure pad 3 and a laser positioning assembly 4. The laser positioning assembly 4 is arranged on one side of the pressure pad 3. The laser positioning assembly 4 includes a guide rail 10, a positioning seat 13, an electric lifting rod 12 and a laser generator 11. The laser generator 11 is rotatably connected to the top of the electric lifting rod 12 through a mounting seat. The mounting seat is used to adjust the irradiation angle of the laser generator 11. The positioning seat 13 is slidably sleeved on the outer wall of the guide rail 10.

[0026] A calibration positioning point 5 is provided on the upper surface of the pressure pad 3, a guide groove 6 is opened on the upper surface of the pressure pad 3, a clamping slider 7 is slidably connected to the inner wall of the guide groove 6, a slider bevel groove 14 is opened on the top of the clamping slider 7, and a positioning groove 15 is opened on the bottom of the inner wall of the slider bevel groove 14.

[0027] The outer wall of the pressure block 2 is rotatably connected to a side branch rod 16, and the bottom end of the side branch rod 16 is rotatably connected to an insert block 17 that adapts to the positioning groove 15. When the material is placed on the pressure pad 3, the side of the material pushes the clamping slider 7 outward. During the outward movement of the clamping slider 7, the return spring 8 is compressed, causing the return spring 8 to generate a reaction force to clamp the material. After the material is positioned, it can maintain a fixed position and prevent it from shifting.

[0028] When the pressure block 2 starts to move downward, the side rod 16 moves downward accordingly. When the pressure block 2 moves downward to a suitable position, the insert block 17 is inserted into the positioning groove 15. As the pressure block 2 moves downward again, the side rod 16 will push the clamping slider 7 to move outward through the insert block 17, and release the clamping state of the material before the pressure block 2 contacts the surface of the material to avoid affecting the subsequent detection results.

[0029] The bottom end of the guide rail 10 is fixedly connected to the upper surface of the workbench 1 .

[0030] Example 2

[0031] like Figure 1-4 As shown, based on Example 1, the present invention provides a technical solution: preferably, a return spring 8 is fixedly connected to the side of the clamping slide 7 away from the pressure pad 3. The end of the return spring 8 away from the clamping slide 7 is fixedly connected to a positioning plate 9. The bottom surface of the positioning plate 9 is fixedly connected to the upper surface of the workbench 1. After the material pressure test is completed, the pressure block 2 moves upward, driving the side rod 16 and the insert block 17 upward. At this time, the clamping slide 7 is reset under the push of the return spring 8.

[0032] The bottom surface of the clamping slide 7 is slidably connected to the upper surface of the workbench 1, and a positioning bevel 18 is fixedly connected to one side of the pressure block 2. The side of the positioning bevel 18 away from the pressure block 2 overlaps one side of the side branch rod 16. The positioning bevel 18 maintains a suitable angle between the side branch rod 16 and the pressure block 2.

[0033] The pressure block 2 is located above the pressure pad 3 , and a pressure driving device for driving the pressure block 2 is provided on the top of the pressure block 2 .

[0034] The following is a detailed description of the working principle of the pressurizing device for testing the mechanical properties of civil engineering materials.

[0035] like Figure 1-4 As shown, when in use, turn on the laser generator 11 so that the laser generated by the laser generator 11 is irradiated onto the pressure pad 3, and then the laser landing point of the laser generator 11 is adjusted through the mounting seat and the positioning seat 13 so that the laser landing point is irradiated onto the calibration positioning point 5. Then, according to the thickness of the material to be tested, the electric lifting rod 12 is adjusted in advance to start, so that it pushes the laser generator 11 up a distance equal to the thickness of the material. After that, after the material is placed on the pressure pad 3, the laser landing point of the laser generator 11 is the center point of pressure applied by the pressure block 2. Subsequently, the position of the material can be adjusted so that the pressure test position is placed in the area of ​​the laser landing point.

[0036] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
