Description

Technical Field

[0001] This utility model belongs to the technical field of material testing devices, and in particular relates to a cement block pressure testing machine. Background Technology

[0002] Cement test blocks are standardized tools, typically cubes or cylinders made from cement raw materials. They are poured, compacted, and then statically cured under specific temperature and humidity conditions. Finally, their strength and quality are tested to evaluate the performance and reliability of the cement.

[0003] Currently, cement test blocks are subjected to various physical and mechanical property tests using a pressure testing machine. However, after the cement test blocks are tested, they become small fragments. Existing pressure testing machines can only test the performance of cement test blocks and cannot crush these fragments. The storage of these fragments requires more space, resulting in an increase in the number of times they need to be handled.

[0004] To address these issues, we provide a cement block pressure testing machine. Utility Model Content

[0005] The purpose of this invention is to provide a cement block pressure testing machine, which solves the problem that existing pressure testing machines can only test the performance of cement blocks, but cannot crush these blocks, and the storage of the blocks requires more space, resulting in more handling.

[0026] For a specific implementation example, please refer to Implementation Example 1. Figure 1-5This utility model is a cement test block pressure testing machine, including a crushing chamber 1; an L-shaped connecting frame 2 is fixed on the surface of the crushing chamber 1; an installation groove 3 is opened on the inner top surface of the L-shaped connecting frame 2; the installation groove 3 extends to the side of the crushing chamber 1 and penetrates the bottom surface of the crushing chamber 1; a lead screw 4 is rotatably installed on the inner top surface of the installation groove 3; a test component 5 is rotatably installed on the side of the lead screw 4; the test component 5 is located above the crushing chamber 1; a linkage component 6 is installed at the bottom end of the lead screw 4; a crushing component 7 is installed on the inner bottom surface of the crushing chamber 1; the crushing component 7 is connected to the linkage component 6.

[0027] Specifically, two fixing plates 8 are symmetrically fixed near the surface of the inner wall of the crushing box 1; a placement plate 9 is fixed between the two fixing plates 8; the placement plate 9 is coaxial with the inner bottom surface of the crushing box 1; a cement test block is placed on the surface of the placement plate 9; and a feeding chute 10 is opened through the surface of the crushing box 1.

[0028] The operation process of this embodiment is as follows: First, the cement test block is placed on the surface of the placement tray 9. Then, the screw 4 is rotated to drive the test component 5 to move downward. Finally, a pressure test is performed on the cement test block on the surface of the placement tray 9. While the screw 4 is rotating, the linkage component 6 is driven to work. The linkage component 6 drives the crushing component 7 to work. The crushing component 7 crushes the small pieces in the crushing box 1 into powder, which is beneficial for storage and saves storage space.

[0029] For a specific embodiment two, please refer to Figure 1-5 Based on the first specific embodiment, the test component 5 includes a slide plate 11 that is threadedly rotated with the lead screw 4; the slide plate 11 is slidably engaged with the inner wall of the mounting groove 3; a slide frame 12 is fixed on the side of the slide plate 11; a limit frame 13 is fixed on the bottom surface of the slide frame 12; a slider 14 is slidably disposed on the inner wall of the slide frame 12; a limit plate 15 is fixed on the bottom surface of the slider 14 that is slidably engaged with the inner wall of the limit frame 13.

[0030] Specifically, a protective cover 16 is fixed to the bottom surface of the limiting plate 15; the inner diameter of the protective cover 16 is larger than the outer diameter of the placement plate 9; the inner wall of the feeding groove 10 is adapted to the circumferential side of the protective cover 16; a number of connecting shafts 17 are evenly distributed in a circular array on the inner top surface of the protective cover 16; a pressure plate 18 is provided between the bottom ends of each connecting shaft 17.

[0031] The operation process of this embodiment is as follows: First, slide the slider 14 upward to move the protective cover 16 upward, so that the protective cover 16 leaves the feeding trough 10. Then, place the cement test block on the surface of the placement tray 9. Then, put the protective cover 16 back into the feeding trough 10 so that the pressure plate 18 is attached to the surface of the cement test block. Then, rotate the screw 4 to move the slide plate 11 downward along the inner wall of the mounting groove 3, and then move the sliding frame 12 downward. The outer surface of the protective cover 16 is made of rubber. First, the sliding frame 12 contacts the periphery of the protective cover 16. Then, the sliding frame 12 begins to squeeze the protective cover 16, which in turn causes the pressure plate 18 to squeeze the cement test block until the cement test block becomes small fragments. A pressure sensor is provided on the pressure plate 18. The pressure sensor is connected to an external controller to send the test pressure value to the controller. The protective cover 16 can block the small fragments and prevent them from splashing out of the feeding trough 10.

[0033] Specifically, a mounting frame 22 is fixed to the bottom surface of the crushing box 1; a servo motor 23 is fixed to the surface of the mounting frame 22; the output end of the servo motor 23 is fixedly connected to the second pulley 20; and several support legs 24 are evenly distributed in a circular array on the bottom surface of the crushing box 1.

[0034] Furthermore, the crushing assembly 7 includes a rotating shaft 25 rotatably disposed on the bottom surface of the crushing box 1; the bottom end of the rotating shaft 25 is fixedly connected to the second pulley 20; and several L-shaped scrapers 26 are evenly fixed in a circular array on the circumferential side of the rotating shaft 25.

[0035] Furthermore, the L-shaped scraper 26 is attached to the inner wall of the crushing box 1; several crushing shafts 27 are evenly fixed in a linear array on the inner wall of the L-shaped scraper 26; several crushing blades 28 are evenly fixed in a circular array on the circumferential side of the crushing shafts 27.

[0036] The operation process of this embodiment is as follows: First, the servo motor 23 is started to drive the second pulley 20 to rotate, and then the belt 21 drives the first pulley 19 to rotate, which in turn drives the lead screw 4 to rotate, which in turn drives the slide plate 11 to move downward along the inner wall of the mounting groove 3, and then drives the sliding frame 12 to slide downward to perform a pressure test on the cement test block. After the pressure test is completed, the cement test block becomes small fragments and is stored inside the crushing box 1.

[0037] The second pulley 20 simultaneously drives the rotating shaft 25 to rotate, which in turn drives the L-shaped scraper 26 on it to rotate, which in turn drives the crushing shaft 27 and the crushing blade 28 on it to crush small pieces. The small pieces are crushed into powder. The bottom of the crushing box 1 is equipped with a feeding pipe. After crushing, the feeding pipe is opened and the crushed powder is collected in a container.
