Description

Technical Field

[0001] The invention relates to the technical field of asphalt concrete penetration detection, in particular to a penetration detection device for asphalt concrete test pieces. Background Art

[0002] The concrete penetration test is an important method for evaluating the concrete's ability to resist the penetration of liquids, gases, or ions, thereby determining its durability. The test simulates the intrusion of corrosive media and water in the external environment to detect the concrete's penetration resistance. The principle of the concrete penetration test is to apply a certain pressure or concentration difference to allow liquid, gas, or ions to pass through the concrete specimen, and then measure the rate or amount of penetration to evaluate the concrete's penetration resistance. The main purpose of the test is to determine the penetration performance of concrete under specific conditions;

[0003] When pouring concrete into the interior of the experimental device for penetration testing, gas can easily enter the interior of the experimental device along with the concrete. When the gas accumulates inside the experimental device, bubbles will appear in the concrete. The presence of bubbles in the concrete will reduce the compactness of the concrete, affecting the accuracy of the concrete penetration test results. Summary of the Invention

[0009] Furthermore, the end of the conical frame away from the sieve frame is inclined toward the surface of the sealing gasket, the end of the hose away from the water supply device is plugged into the inner wall of the cylindrical tube, the top of the calibrated tube is fixedly connected to the bottom of the disc, and is connected to the second detection frame through the cylindrical tube.

[0010] Furthermore, the exhaust component includes a circular groove ring, which is arranged at one end of the detection frame 1 and the detection frame 2 that are close to each other, and the end of the detection frame 1 and the detection frame 2 that are close to each other are rotatably connected to the inner wall of the circular groove ring, the end of the center frame is fixedly connected to an extrusion ring, the bottom of the extrusion ring is hinged to a tripod, the bottom of the tripod is hinged to a circular hole rod, the surface of the detection frame 2 is fixedly connected to a limiting ring, the surface of the limiting ring is fixedly connected to a sliding rod frame, the surface of the circular groove ring is fixedly connected to an engaging ring, the surface of the engaging ring is engaged with a tooth plate, the surface of the tooth plate is fixedly connected to a connecting rod, the end of the connecting rod away from the tooth plate is fixedly connected to the end of the circular hole rod, and the inner wall of the circular groove ring is fixedly connected to a mixing plate.

[0011] Furthermore, the inner wall of the round hole rod is slidably connected to the surface of the slide rod frame, the number of the connecting rods is two, the two connecting rods are arranged oppositely, and the end of the slide rod frame extends to the outer end of the round hole rod.

[0014] The present invention has the following beneficial effects:

[0015] When the present invention needs to add concrete to the interior of the detection frame 1, the electric push rod is started to push the center frame upward, and the center frame slides on the surface of the round rod. The round rod is used to limit the center frame to improve the stability of the center frame during movement. When the center frame moves, it pushes the disc in the detection frame 1 to move upward. At this time, the disc in the detection frame 2 will also move upward with the curved plate. When the disc is separated from the inner wall of the detection frame 1, concrete can be added to the interior of the detection frame 1 and the detection frame 2 for penetration testing. At this time, the disc is started to enter the interior of the detection frame 1 to seal the detection frame 1, and the water supply device is started. The device pushes the water to flow into the inside of the hose. The water flows through the hose into the inner wall of the cylindrical tube and is gathered on the surface of the concrete through the sieve frame. The water that penetrates through the concrete will pass through the cylindrical tube into the inside of the graduated tube. The staff can observe the height of the water flow entering the graduated tube to test the permeability of the concrete. When it is necessary to unload the concrete inside the detection frame 2, the center frame is started to push the bent plate downward. When the bent plate moves, it will push the disc in the detection frame 2 to move downward. At the same time, the disc in the detection frame 1 can push the concrete to move downward, thereby improving the convenience of replacing the concrete.

[0016] When the center frame of the present invention moves, the extrusion ring pushes the tripod to deform. When the tripod expands, it pushes the circular hole rod to slide on the surface of the sliding rod frame. When the circular hole rod moves, it pushes the tooth plate to move through the connecting rod. When the tooth plate moves, it pushes the circular groove ring to rotate at the bottom of the detection frame through the meshing ring. When the circular groove ring rotates, it drives the mixing plate to rotate. The mixing plate is used to stir the concrete flow, so as to avoid gas storage in the concrete to generate bubbles, which affects the detection result of concrete penetration.

[0017] When the linkage rod of the present invention moves, it pushes the spring piece to move through the connecting rod. When the spring piece moves, it drives the triangular block to move on the surface of the groove plate. The triangular block can extend into the groove of the groove plate by utilizing the elasticity of the spring piece. When the groove plate continuously contracts and extends during movement, vibration will be generated when the triangular block contacts the inner wall of the groove of the groove plate. The vibration will be transmitted to the second detection frame through the positioning ring. The gas in the concrete can be quickly discharged by the vibration, so as to prevent the gas from accumulating inside the concrete and affecting the penetration detection result.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
