Description

Technical Field

[0001] This utility model relates to the field of shale ceramsite testing technology, specifically a device for testing the compressive strength of shale ceramsite. Background Technology

[0002] Shale ceramsite, as an important lightweight aggregate, has wide applications in various fields such as construction and oil extraction. Its compressive strength is one of the key indicators for evaluating its quality and performance, and is of great significance for ensuring the safety and stability of related engineering structures. In practical engineering applications, the compressive strength of shale ceramsite directly affects its performance in materials such as concrete.

[0003] Currently, testing the compressive strength of shale ceramsite typically requires sending samples to specialized testing institutions for testing using large hydraulic presses. These institutions are usually equipped with advanced testing equipment and skilled technicians, enabling them to provide relatively accurate test results. However, this method has some significant drawbacks. First, sending samples to specialized institutions consumes considerable time and effort, and for situations requiring rapid test results, this delay can impact project progress and decision-making. Second, specialized institutions usually charge fees for their testing services, increasing the testing costs for companies. Furthermore, large hydraulic presses are not only expensive but also bulky, requiring significant floor space, and their maintenance and operation require specialized technicians, resulting in high purchase and operating costs for most companies or laboratories.

[0004] The irregular elliptical shape of shale ceramsite presents additional challenges for compressive strength testing. When using a hydraulic press, its irregular shape leads to uneven stress distribution when placed directly on the press. Under the pressure of the hydraulic press, the irregularly shaped shale ceramsite may roll or shift, preventing the pressure from being applied accurately to its intended location, thus causing errors in the test results. This error not only affects the accurate assessment of the compressive strength of shale ceramsite but may also mislead subsequent engineering applications and quality control.

[0005] Therefore, a device for testing the compressive strength of shale ceramsite is needed to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for testing the compressive strength of shale ceramsite.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shale ceramsite compressive strength testing device, comprising a mounting plate, an L-shaped plate fixedly connected to the upper surface of the mounting plate, a hydraulic cylinder fixedly mounted on the side of the L-shaped plate near the mounting plate, a pressure sensor fixedly mounted at the bottom end of the hydraulic cylinder, a placement box fixedly connected to the upper surface of the mounting plate, a clamping mechanism provided on the placement box, the clamping mechanism comprising two sets of clamping unit assemblies, each clamping unit assembly comprising a lead screw threadedly connected inside the placement box, one end of the lead screw rotatably connected to a square tube, and an arc-shaped clamping plate mounted on one side of the square tube.

[0008] Preferably, in the above-mentioned shale ceramsite compressive strength testing device, the inner wall of the square cylinder is slidably connected to a slider, and one side of the slider is fixedly connected to an arc-shaped clamping plate.

[0009] Preferably, in the above-mentioned shale ceramsite compressive strength testing device, the side of the arc-shaped clamping plate away from the slider is fixedly equipped with an anti-slip rubber strip.

[0010] Preferably, in the above-mentioned shale ceramsite compressive strength testing device, the inner wall of the square cylinder is fixedly connected to a sliding rod, and the sliding rod is slidably connected to the inside of the slider.

[0011] Preferably, in the above-mentioned shale ceramsite compressive strength testing device, the bottom surface of the slider is fixedly connected to a spring, and the bottom end of the spring is fixedly connected to the inner bottom wall of the square tube.

[0012] Preferably, in the above-mentioned shale ceramsite compressive strength testing device, the other end of the lead screw is fixedly connected to a rotating wheel, and one side of the square tube is fixedly connected to a stabilizing rod, which slides through the placement box.

[0013] Preferably, in the above-mentioned shale ceramsite compressive strength testing device, the mounting plate is internally threaded with a threaded rod, and the bottom end of the threaded rod is fixedly connected with a foot.

[0014] Preferably, in the above-mentioned shale ceramsite compressive strength testing device, a handle and a display screen are fixedly installed on the upper surface of the mounting plate.

[0015] The beneficial effects of this invention are as follows: the arc-shaped clamping plate and anti-slip rubber pad in the clamping mechanism can firmly clamp the shale ceramsite, preventing it from sliding during testing, thus ensuring that pressure is accurately applied to the ceramsite. This invention eliminates the need to send shale ceramsite samples to professional testing institutions for testing with large hydraulic presses, avoiding the time and effort spent on sample delivery. Furthermore, the device has a compact overall structure, is easy to transport, and can be easily moved and its testing position adjusted via the handle on the mounting plate. This allows for rapid testing of the compressive strength of shale ceramsite in various settings, meeting the need for quick test results. Attached Figure Description

Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] like Figures 1-3 As shown, a shale ceramsite compressive strength testing device includes a mounting plate 1. The mounting plate 1 has threaded rods 8 internally connected to it, and base feet 9 are fixedly connected to the bottom ends of the threaded rods 8. Four threaded rods 8 and four base feet 9 are provided, positioned at the four corners of the mounting plate 1. The mounting plate 1 serves as the basic support component of the entire device, used to fix and support other components, ensuring the structural stability of the device. The horizontal state can be adjusted by the support of the four threaded rods 8 and base feet 9. Two handles 10 and a display screen 5 are fixedly connected to the upper surface of the mounting plate 1. The handles 10 facilitate the operator's movement of the device and adjustment of its position. An L-shaped plate 2 is fixedly connected to the upper surface of the mounting plate 1 for mounting a hydraulic cylinder 3, providing the mounting position and support for the hydraulic cylinder 3. The hydraulic cylinder 3 is fixedly mounted on the side of the L-shaped plate 2 closest to the mounting plate 1, and a pressure sensor 4 is fixedly mounted at the bottom end of the hydraulic cylinder 3. After the hydraulic cylinder 3 is activated under control, it can extend downwards to provide downward pressure to the pressure sensor 4 for pressure testing of the shale ceramsite. Pressure sensor 4 is installed at the bottom of hydraulic cylinder 3 and can convert the pressure it receives into an electrical signal and transmit it to display screen 5.

[0023] A placement box 6 is fixedly connected to the upper surface of the mounting plate 1, and a clamping mechanism 7 is provided on the placement box 6. The clamping mechanism 7 includes two sets of clamping unit assemblies. Each clamping unit assembly includes a lead screw 701 threadedly connected to the inside of the placement box 6. A square tube 702 is rotatably connected to the left end of the lead screw 701. A slider 703 is slidably connected to the inner wall of the square tube 702. An arc-shaped clamping plate 704 is fixedly connected to the left side of the slider 703. An anti-slip rubber strip 705 is fixedly installed on the side of the arc-shaped clamping plate 704 away from the slider 703. The anti-slip rubber strip 705 increases friction and prevents the ceramsite from sliding.

[0024] A sliding rod 706 is fixedly connected to the inner wall of the square tube 702, and the sliding rod 706 is slidably connected to the inside of the slider 703. A spring 707 is fixedly connected to the bottom surface of the slider 703, and the bottom end of the spring 707 is fixedly connected to the inner bottom wall of the square tube 702. A rotating wheel 708 is fixedly connected to the right end of the lead screw 701, and a stabilizing rod 709 is fixedly connected to the right side of the square tube 702, which slides through the placement box 6. The slider 703 can slide downward along the sliding rod 706 along the inner wall of the square tube 702, preventing the clamping mechanism 7 from completely fixing the shale ceramsite, ensuring that the bottom of the shale ceramsite always maintains effective contact with the placement box 6 under pressure, and will not detach from the bottom foundation due to excessive tightness. At the same time, the spring 707 connected between the bottom surface of the slider 703 and the inner bottom wall of the square tube 702 initially holds the slider 703 at the top of the square tube 702, allowing the slider 703 to slide smoothly down the sliding rod 706 when needed.

[0025] Working Principle: When testing the compressive strength of shale ceramsite, the shale ceramsite is placed in the placement box 6. Rotating the rotating wheel 708 causes the lead screw 701 to rotate synchronously. Since the lead screw 701 is threadedly connected to the placement box 6, it moves axially as it rotates, thus pushing the square cylinder 702 to move horizontally within the placement box 6. During this process, the stabilizing rod 709 slides within the placement box 6, acting as a guide to ensure smooth operation. As the square cylinder 702 moves, it brings the arc-shaped clamping plate 704 closer to the shale ceramsite. The arc-shaped clamping plates 704 on both sides firmly clamp the shale ceramsite within the placement box 6. The anti-slip rubber pads 705 on the arc-shaped clamping plates 704 increase the friction between the shale ceramsite and the plate, effectively preventing the ceramsite from slipping during the test.

[0026] Once the shale ceramsite is securely clamped, hydraulic cylinder 3 is activated. Hydraulic cylinder 3 extends downwards, causing pressure sensor 4 to gradually approach and contact the shale ceramsite. As hydraulic cylinder 3 continues to apply pressure, slider 703 slides downwards along slide rod 706 on the inner wall of square cylinder 702, reducing the relative vertical friction between the shale ceramsite and anti-slip rubber pad 705, which could affect test accuracy. Initially, spring 707 holds slider 703 at the top of square cylinder 702. At this time, the arc-shaped clamping plate 704 maintains a certain distance from the bottom surface of placement box 6, while the bottom of the shale ceramsite contacts the bottom surface of placement box 6. During the pressure application process of hydraulic cylinder 3 on the shale ceramsite, pressure sensor 4 converts the applied pressure into an electrical signal and transmits it to display screen 5.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
