The lead screw moves through the nut seat, and the movement of the nut seat drives the first hanging ear and the shifting plate to move synchronously. A dust removal assembly is set above the shifting plate. The dust removal assembly includes a dust removal push plate. A hanging plate is fixedly connected to one inner wall of the dust removal push plate. The dust removal push plate is engaged and installed at the top of the shifting plate.

The lead screw is movably installed in one sliding groove, and the first guide rod is fixedly installed in the other sliding groove. A second hanging ear is also fixedly connected to one side of the displacement plate. A slider is fixedly connected to the bottom end of the second hanging ear. The slider and the nut seat are movably engaged in the corresponding sliding groove, and the first guide rod movably passes through the corresponding slider.
[0009] According to the aforementioned compressive strength testing device, the nut seat and the lead screw are connected by a thread. The servo motor is fixedly installed on the rear end wall of the mounting base.

[0012] According to the aforementioned compressive strength testing device, the top of the displacement plate is provided with a groove, and the bottom of the dust removal push plate is fixedly connected with a protrusion, which can be movably engaged in the groove.

[0014] This invention provides a compressive strength testing device. It has the following beneficial effects:
[0015] (1) When conducting a compressive strength test on concrete, workers usually place the concrete block under the hydraulic cylinder by hand, within the specified position range, and then conduct the compressive strength test. After the test, the debris needs to be cleaned with a brush before the next sample is tested. The whole process is time-consuming. This application sets a displacement component in the cavity of the mounting base, and the assembly base is fixedly installed on the mounting base and the base. A pushing unit is set to move the displacement plate. The displacement plate moves the concrete block under the hydraulic cylinder. A clamping block unit can place the concrete block at the center position under the hydraulic cylinder, which effectively reduces experimental errors. After the test, a dust removal component is set to engage the dust removal push plate with the displacement plate. During the movement of the displacement plate, the dust removal push plate is pushed to move and clean the debris in the cavity of the assembly base in one go, which improves the testing efficiency.

The second hanging ear is fixedly connected to the shift plate, and the slider is movably engaged in the first guide rod. The slider is fixedly connected to the second hanging ear. During operation, the servo motor drives the lead screw to rotate, and the lead screw moves through the nut seat. The nut seat is fixedly connected to the first hanging ear, so that the first hanging ear drives the shift plate to move synchronously. The second hanging ear and the first guide rod play a limiting and guiding role for the shift plate, making the movement process more stable. By setting dust baffles fixedly connected to the side of the first and second hanging ears near the servo motor, the dust baffles are arc-shaped, which effectively prevents dust from falling into the groove and avoids dust causing the nut seat to move unevenly, ensuring the stable operation of the device.
[0017] (3) By opening a groove at the top of the shift plate and fixing a protrusion to the bottom of the dust removal push plate, when cleaning debris, insert the protrusion into the groove, the shift plate moves and pushes the dust removal push plate to move, a scraper is fixedly connected to one end of the dust removal push plate, and a rubber pad is fixedly connected to the bottom of the hanging plate to ensure that the dust removal push plate moves to one side to complete the cleaning work, and the cleaning effect is better.

[0032] Specifically, by opening grooves at both ends of the U-shape of the mounting base 14, the lead screw 18 is movably installed in one groove, and the first guide rod 19 is fixedly installed in the other groove. The second lug 26 is fixedly connected to the shift plate 15, and the slider 25 is movably engaged in the first guide rod 19. The slider 25 is fixedly connected to the second lug 26. During operation, the servo motor 20 drives the lead screw 18 to rotate, and the lead screw 18 moves through the nut seat 27. The nut seat 27 is fixedly connected to the first lug 16, so that the first lug 16 drives the shift plate 15 to move synchronously. The second lug 26 and the first guide rod 19 play a limiting and guiding role for the shift plate 15, making the movement process more stable. By setting dust baffles 17 fixedly connected to the side of the first lug 16 and the second lug 26 near the servo motor 20, the dust baffles 17 are arc-shaped, which effectively prevents dust from falling into the groove and prevents dust from causing the nut seat 27 to move unevenly, ensuring the stable operation of the device.

The two clamping plates 22 are located at both ends of the rotating shaft 23, and the two clamping plates 22 are threadedly connected to the rotating shaft 23. A right-angle gear reducer motor 32 is fixedly installed on the outer wall of the front end of the shift plate 15. The shift plate 15 is hollow, and the output end of the right-angle gear reducer motor 32 is connected to the rotating shaft 23 through two sets of helical gears.
[0034] Specifically, three sets of rectangular slots are opened on the rear wall of the shift plate 15. A rotating shaft 23 is movably installed in the middle set of rectangular slots, and second guide rods 24 are fixedly installed in the rectangular slots on both sides. The rotating shaft 23 and the second guide rods 24 both movably pass through two clamping plates 22. A set of reverse threads is opened on the outer wall of the rotating shaft 23. The two clamping plates 22 are located at both ends of the rotating shaft 23, and the two clamping plates 22 are threadedly connected to the rotating shaft 23.

[0037] The working principle of the compressive strength testing device disclosed in this application is as follows: When conducting a compressive strength test on concrete, the operator usually places the concrete block under the hydraulic cylinder 12 by hand, within the specified position range, and then conducts the compressive strength test. After the test, the debris needs to be cleaned with a brush before the next sample is tested. The whole process is quite time-consuming. This application improves the device by setting a displacement component 13 in the cavity of the mounting base 11, fixing the assembly base 14 on the mounting base 11 and the base 10, setting a pushing unit to move the displacement plate 15, and moving the displacement plate 15 to move the concrete block under the hydraulic cylinder 12.
