Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0020] Reference Figure 1-3A device for testing the hardness of precast concrete slabs includes a base plate 1. Support rods 2 are symmetrically installed on one end of the top outer wall of the base plate 1, and a top plate 3 is installed on the top outer wall of the support rods 2. A hydraulic push rod 4 is installed at the center of one end outer wall of the top plate 3, and a pressure block 5 is installed on the bottom outer wall of the hydraulic push rod 4. Protective components 6 are provided on the four sides of the hydraulic push rod 4 on the top outer wall of the base plate 1, and a storage component is provided on one end outer wall of the base plate 1. The hydraulic push rod 4 on the top of the base plate 1 is installed on the base plate 1 through the top plate 3 and the support rods 2, so that there is a large gap between the base plate 1 and the hydraulic push rod 4, which makes it easy to place the precast slab in it, facilitates use, and avoids interference.

[0021] The protective component 6 includes sliding grooves 8 at both ends of the top of the base plate 1, insertion grooves at both ends of the top plate 3 on the outer wall of the top of the base plate 1, and insertion plates 9 slidably connected in the insertion grooves and sliding grooves 8. Insertion plates 9 are inserted into the sliding grooves 8 and insertion grooves. Personnel can observe the inspection process of the precast slab through the protective holes 10. The insertion plates 9 cooperate with the protective holes 10 to protect the inspection process, which facilitates observation and improves safety.

[0022] The bottom outer wall of the plug plate 9 is slidably connected to the inner wall of the sliding groove 8 and the inner wall of the plug groove, and the outer wall of the plug plate 9 is provided with protective holes 10 distributed at equal intervals. The plug plate 9 is located in the sliding groove 8 and the plug groove to block the four outer walls of the hydraulic push rod 4, preventing the debris generated after the precast plate breaks from splashing, and improving the safety of the inspection.

[0023] A control panel 7 is installed on the other end of the top outer wall of the base plate 1, and a pressure sensor is installed in the pressure block 5. The pressure sensor and the hydraulic push rod 4 are connected to the input end of the control panel 7 through a signal line. The control panel 7 starts the hydraulic push rod 4, and the hydraulic push rod 4 applies pressure to the precast plate through the pressure block 5. The pressure generated by the hydraulic push rod 4 and the pressure value displayed by the pressure sensor are displayed on the control panel 7. The detected pressure is recorded twice to reduce errors.

[0024] The storage component includes a battery compartment 11 located at the center of one end of the base plate 1, a hidden groove located at the center of the battery compartment 11 on the outer wall of the base plate 1, and a battery 12 placed in the battery compartment 11. The battery 12 is confined in the battery compartment 11 by a sealing plate 13. The battery 12 provides power for the start of the hydraulic push rod 4, making it easy to move and use, and convenient for use when going out.

[0025] A cover plate 13 is installed in the hidden slot, and one outer wall of the cover plate 13 is in contact with the outer wall of the battery 12.

[0026] The hydraulic push rod 4 is connected to the control panel 7 via a wire, and the control panel 7 is connected to the battery 12 via a wire.

[0027] Working principle: During use, move the bottom plate 1 to the precast slab production site. Usually, pads are placed at the bottom of the precast slab to raise it. Insert one end of the bottom plate 1 under the bottom of the precast slab, and then raise the bottom plate 1 so that it contacts the outer wall of the bottom of the precast slab. Place the insertion plate 9 in the sliding groove 8 and the insertion groove on the observation surface of the operator. The operator observes through the protection holes 10 on the insertion plate 9. Start the hydraulic push rod 4 through the control panel 7. The hydraulic push rod 4 applies pressure to the precast slab through the pressure block 5. The pressure generated by the hydraulic push rod 4 and the pressure value displayed by the pressure sensor are shown on the control panel 7, and the detected pressure is recorded twice to reduce errors. If the precast slab does not break at the appropriate pressure value, it is considered qualified; sampling detection can also be carried out. At this time, the insertion plate 9 is located in the sliding groove 8 and the insertion groove to block the outer walls on all four sides of the hydraulic push rod 4, preventing the debris generated after the precast slab breaks from splashing everywhere and improving the safety of the detection.
