Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for detecting the compressive strength of a road surface during highway construction. Background Art

[0002] In the field of building construction, highway construction pavement compression resistance testing equipment usually refers to equipment used to evaluate the vehicle load that the pavement material can withstand after construction is completed. This equipment can help engineers ensure that the pavement can meet the design requirements, thereby ensuring the durability and safety of the road.

[0003] After searching, a highway pavement compression resistance detection device with announcement number CN217605493U includes a main unit and a heat dissipation mechanism. A display screen is provided on the front of the main unit near the upper position, a detection frame is provided on the right side of the main unit, a pressure plate is provided on the upper end of the detection frame, and a sensor is provided on the lower end of the detection frame. The utility model sets a heat dissipation mechanism, turns on the motor, and makes the fan rotate. Wind blows through the inside of the main unit and then blows out from the heat dissipation slot. The dust collection net in the heat dissipation frame absorbs dust inside and outside the main unit. At regular intervals, the pin is pulled out of the slot, the heat dissipation frame is removed for cleaning, and the dust collection net is pulled out of the card slot for cleaning. At present, most detection devices do not have air cooling and heat dissipation, and the heat dissipation slot is easy to get dust, so that the inside of the main unit is covered with dust, resulting in main unit failure. The application of this device effectively avoids the above problems and improves the practicality of the equipment.

[0004] Based on the above patent, by setting a heat dissipation mechanism, turning on the motor, making the fan rotate, the wind blows through the inside of the main unit, and then blows out from the heat dissipation slot, the dust collection net in the heat dissipation frame absorbs the dust inside and outside the main unit, and the pin is pulled out of the slot at intervals, the heat dissipation frame is removed for cleaning, and the dust collection net is pulled out from the card slot for cleaning. At present, most detection devices do not have air cooling, and the heat dissipation slot is easy to get dust, so that the inside of the main unit is covered with dust, resulting in main unit failure. The application of this device effectively avoids the above problems and improves the practicality of the equipment. By setting a cleaning mechanism, the road sampling material Place it on the sensor, then control the host to press the pressure plate down to obtain data. After completion, there will be a lot of residual debris on the surface of the sensor. Turn on the air pump, and the wind enters from the air inlet pipe, and then the wind is sprayed out from the nozzle through the booster pump to blow away the debris on the sensor. At present, most detection devices rely on manual cleaning, which is very troublesome. The application of this device effectively avoids the above problems and improves the practicality of the equipment. However, when squeezing road samples, the road samples will be broken due to the strong squeezing force, so that debris will splash out, which will cause harm to the staff, and the air pump is not effective in cleaning larger debris.
