Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete block hardness detection device. Background Art

[0002] Concrete blocks are widely used in construction projects, and the hardness of concrete is particularly important. Only by ensuring the hardness of concrete can the firmness of the building structure be guaranteed, thereby extending the service life of the building structure. Therefore, the hardness of concrete needs to be tested before use.

[0003] Publication No. CN218349967U discloses a safety detection device for the hardness of a concrete block for construction. After the detection of the concrete block is completed, the cylinder drives the protective shell and the tooth plate to reset and causes the gear to drive the screw to rotate, thereby causing the slider to drive the placement plate to move to the outside of the device. Therefore, the operator does not need to put his arm into the device when cleaning the concrete block, thereby increasing the safety of the operator when using the device; the cylinder pushes the protective shell and the tooth plate to move downward, and the tooth plate and the gear are engaged to cause the screw to rotate and cause the slider to drive the placement plate to move to the lower side of the protective shell, and then the hardness of the concrete block is detected by the pressure head, and the splashing concrete block is blocked by the protective shell, thereby reducing the possibility of concrete blocks causing harm to the operator. However, the patent still has the following problems in actual use:

[0004] After the device has completed the concrete block inspection, the cylinder drives the protective shell and the tooth plate to reset and causes the gear to drive the screw to rotate, thereby causing the slider to drive the placement plate to move to the outside of the device. Therefore, the operator does not need to put his arm into the device when cleaning the concrete block, thereby increasing the safety of the operator when using the device. Since the pressure head is in rigid contact with the concrete block for a long time, the staff needs to check and repair the pressure head regularly, but the device does not have the function of quick installation and disassembly of the pressure head, which causes inconvenience to the staff when using it.

[0005] A concrete block hardness testing device is proposed to solve the above problems. Utility Model Content
