Description

Technical Field

[0001] The utility model belongs to the technical field of performance detection, and particularly relates to a multifunctional asphalt pavement performance detection device. Background Art

[0002] The multifunctional asphalt pavement performance detection device integrates sampling, testing and data analysis functions. It includes a high-precision sampler for uniformly extracting samples from the pavement, a testing module that can perform performance tests such as density, compressive strength, and stripping resistance, a data recording and analysis system for real-time recording and analyzing detection data; and a user interface for providing intuitive operation and result display.

[0003] The patent with the publication number CN115753508A discloses an asphalt composition detection device for road asphalt pavement, which includes a stirring mechanism arranged inside a stirring tank. There is an opening and closing mechanism between the stirring tank and the base. A detection mechanism is arranged inside the detection tank. The invention stirs the asphalt composition in multiple directions by starting the stirring mechanism to improve the mixing efficiency of the asphalt composition. When stirring for a certain time, the solenoid valve is opened, and the asphalt mixture inside the stirring tank enters the inside of the detection tank through the connecting pipe. Then the solenoid valve is closed, and the detection mechanism is started. The detection mechanism starts to detect the viscosity parameter of the asphalt inside the detection tank. If the viscosity parameter does not meet the requirements, additional materials are added for stirring until the viscosity parameter meets the requirements. Then the opening and closing mechanism is opened to unload the asphalt mixture inside the stirring tank to the bottom of the base, which can detect the viscosity of the asphalt mixture without interruption of stirring and is convenient to use.

[0004] However, the current detection device has the following problems: After the detection of the previous asphalt is completed, it is difficult to clean the residual asphalt inside the detection device, which will cause the residual asphalt to mix with the asphalt to be detected in the next test, thus affecting the accuracy of the next asphalt sampling. Therefore, we propose a multifunctional asphalt pavement performance detection device. Summary of the Utility Model

[0013] The technical effects achieved by the present utility model are:

[0014] With the provision of the cleaning device in the present utility model, the cooperation of the scraping plate, notch 1, and dirt removal plate enables the rotation of the output end of the motor to drive the rotation of the threaded rod. Since there is no restriction on the rotation of the scraping plate on the threaded rod, the rotation of the threaded rod drives the scraping plate to rotate and move up and down, thereby scraping off the impurities remaining from the sampling on the inner wall of the protective housing, thus avoiding affecting the accuracy of the next asphalt sampling. At the same time, through the cooperation of the double-shaft motor, gear, rotating ring, L-shaped movable frame, telescopic rod, long strip connecting rod, baffle, worm, abutting block, rotating rod, and L-shaped fixing rod, the reciprocating movement of the telescopic rod will drive the reciprocating movement of the long strip connecting rod, and the reciprocating movement of the long strip connecting rod drives the reciprocating movement of the dirt removal plate.

[0015] With the provision of the fixing device in the present utility model, the cooperation of the connecting rod, fixing box, nail plate, slideway, slide rod, stop block, notch 2, sliding block, L-shaped pipe, and spring enables the stretching of the spring to move the nail plate outwards, and the nails of the nail plate are exposed outside the fixing box and penetrate into the taken asphalt to fix the sampled product, so that the sample will not come off during the sampling process. When the sample needs to fall off, when the long strip connecting rod moves outwards, it drives the L-shaped pipe to move outwards, and the L-shaped pipe moving outwards drives the stop block to move outwards. When the stop block moves outwards, the spring retracts its elastic force to retract the nail plate into the fixing box, thus enabling the sample to fall off smoothly. Description of the Drawings

[0026] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0027] As Figures 1 - 8 shown, a multifunctional asphalt pavement performance detection device includes an asphalt paving detection device 1. A plurality of first fixing strips 2 are fixedly connected to the left side of the asphalt paving detection device 1. A protective housing 3 is fixedly connected between the plurality of first fixing strips 2. The upper side of the inner wall of the protective housing 3 is fixedly connected with a water inlet pipe 4. The top of the protective housing 3 penetrates and rotates a threaded rod 5. The threaded rod 5 is driven by a motor, and the motor is fixedly connected to the top of the protective housing 3. A cleaning device 7 is arranged on the outer wall of the threaded rod 5. The cleaning device 7 includes a scraper 71. The inner wall of the scraper 71 is threadedly connected to the threaded rod 5. The left side of the scraper 71 is fixedly connected with a motor protection box 74. Both sides of the outer wall of the motor protection box 74 are fixedly connected with baffles 711. A biaxial motor 75 is fixedly connected to the inner wall of the motor protection box 74. Two output ends of the biaxial motor 75 are fixedly connected with two worms 712. One end of the two worms 712 away from the biaxial motor 75 has a block 713. Both sides of the motor protection box 74 are fixedly connected with L-shaped fixing rods 716. The bottoms of the two L-shaped fixing rods 716 are rotatably connected with a gear 76. The bottom of the gear 76 is fixedly connected with a rotating rod 714. The circumferential surface of the rotating rod 714 is fixedly connected with a swivel ring 77. The bottom of the swivel ring 77 is fixedly connected with an L-shaped movable frame 78. The bottom of the L-shaped movable frame 78 is fixedly connected with a telescopic rod 79. One end of the telescopic rod 79 away from the L-shaped movable frame 78 is fixedly connected with a long strip connecting rod 710. First notches 72 are opened on both sides of the scraper 71. One end of the long strip connecting rod 710 away from the telescopic rod 79 is fixedly connected with a decontamination plate 73;

[0028] The worm 712 meshes with the gear 76, and the baffle 711 is on the movement track of the telescopic rod 79;

[0029] Two notches one 72 are opened on both sides of the scraper 71, and two dirt removal plates 73 are both slidably connected to the inner walls of the two notches one 72;

[0030] According to the above structure, when sampling the asphalt pavement, the asphalt paving detection device 1 is pushed to the designated position, the water pipe is connected to the water inlet pipe 4, and water flows into the protective housing 3, preventing the equipment from overheating due to ground friction during sampling of the asphalt paving detection device 1, thereby playing a role in cooling and reducing friction. When the sampling is completed, the motor is started, and the rotation of the output end of the motor drives the threaded rod 5 to rotate. Since there is no restriction on the rotation of the scraper 71 on the threaded rod 5, the rotation of the threaded rod 5 drives the scraper 71 to rotate and move up and down, thereby scraping off the impurities remaining on the inner wall of the protective housing 3 during sampling, thus avoiding affecting the accuracy of the next asphalt sampling; at the same time, the double-shaft motor 75 is turned on, and the two output shafts of the double-shaft motor 75 will cause the two worms 712 to rotate. The worm 712 drives the rotating rod 714 to rotate through the gear 76. The rotation of the rotating rod 714 drives the rotation of the L-shaped movable frame 78. The rotation of the L-shaped movable frame 78 drives the telescopic rod 79 to move back and forth on the surface of the scraper 71 at the eccentric position at the bottom of the L-shaped movable frame 78. The back-and-forth movement of the telescopic rod 79 will drive the reciprocating movement of the long strip connecting rod 710. The reciprocating movement of the long strip connecting rod 710 drives the reciprocating movement of the dirt removal plate 73. The reciprocating movement of the dirt removal plate 73 will scrape off the residues on the scraper 71, thus avoiding the problem of residues accumulating on the scraper 71.

[0031] As Figures 1 - 8 shown, a fixing device 8 is arranged at the bottom of the scraper 71. The fixing device 8 includes a connecting rod 81. The top of the connecting rod 81 is fixedly connected to the bottom of the scraper 71. The bottom of the connecting rod 81 is fixedly connected with a fixing box 82. A nail plate 83 is slidably connected to the inner wall of the fixing box 82. Two sliding grooves 84 are opened at the top of the nail plate 83. A sliding rod 85 is slidably connected to the inner walls of the two sliding grooves 84. The top of the two sliding rods 85 is slidably connected with a stopper 86. A second card slot 87 is opened at the top of the stopper 86. A sliding block 88 is slidably connected to the inner wall of the second card slot 87. The top of the sliding block 88 is fixedly connected with an L-shaped pipe 89. The top of the L-shaped pipe 89 is fixedly connected to the outer wall of the long strip connecting rod 710;

[0032] The sliding block 88 is in contact with the stopper 86, and the fixing box 82 is on the movement track of the stopper 86;

[0033] The nail plate 83 is on the movement track of the stopper 86, and several springs 810 are arranged between the fixing box 82 and the nail plate 83;

[0034] According to the above structure, when sampling the asphalt pavement, the sampled sample is likely to slip from the protective housing 3 due to continuous vibration. When the long connecting rod 710 reciprocates, it will drive the sliding block 88 to slide in the second slot 87 through the L-shaped pipe 89. The sliding of the sliding block 88 drives the stopper 86 and the slideway 84 to slide inside the inner wall of the sliding rod 85, so that the stopper 86 enters the fixed box 82, and then the spring 810 is stretched. The stretching of the spring 810 will move the nail plate 83 outwards, and the nails of the nail plate 83 are exposed outside the fixed box 82. The nails are driven into the taken asphalt to fix the sampled sample, so that the sampled sample will not break away during the sampling process. When the sample needs to fall off during sampling, when the long connecting rod 710 moves outwards, it drives the L-shaped pipe 89 to move outwards. The outward movement of the L-shaped pipe 89 drives the stopper 86 to move outwards. When the stopper 86 moves outwards, the spring 810 retracts its elastic force and retracts the nail plate 83 into the fixed box 82, so that the sample can fall off smoothly.

[0035] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
