DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] For example 1, please refer to Figures 1-4 , a road asphalt sample detection device based on an intelligent sensor, comprising: The detection chamber 100 is equipped with a detection sensor 200; The asphalt placement table 300 has its bottom mounted in the testing chamber 100 via an electric telescopic rod. A horizontally movable platform 400 is mounted inside the testing chamber 100. A rotating roller 500 driven by a servo motor is mounted on the side of the movable platform 400. The asphalt sample to be tested is placed on the asphalt placement table 300, the asphalt placement table 300 is activated, and the asphalt sample is moved to the bottom position of the rotating roller 500. The rotating roller 500, driven by the servo motor, is activated to rapidly rotate over the asphalt sample, and the detection sensor 200 is used to perform the corresponding detection operation. The side transmission of the rotating roller 500 is connected to the hydraulic chamber 1 601, and the bottom of the asphalt placing platform 300 is equipped with a force plate 612 by setting a spring 2 611. A transmission part for transmission is installed between the hydraulic chamber 1 601 and the force plate 612. The transmission part includes a hydraulic chamber 2 605 installed on the side of the movable platform 400. The inner wall of the hydraulic chamber 1 601 is slidably connected to the sliding block 603 by setting an elastic telescopic rod 602, and the side of the hydraulic chamber 1 601 is slidably connected to the arc plate 604 by setting a piston. When performing the detection operation, the rapidly rotating rotating roller 500 drives the hydraulic chamber 1 601 connected to it to rotate rapidly, so that the sliding block 603 in the hydraulic chamber 1 601 stretches the elastic telescopic rod 602 under the action of centrifugal force and moves along the inner wall of the hydraulic chamber 1 601, thereby squeezing the oil originally stored in the hydraulic chamber 1 601, causing the oil to flow to the end close to the arc plate 604, driving the arc plate 604, which is slidably connected to the hydraulic chamber 1 601 by a piston, to extend from the hydraulic chamber 1 601.

[0022] The top of hydraulic chamber 2 605 is slidably connected to a force-bearing rod 1 606 via a piston. Force-bearing rod 1 606 is located at the bottom of curved plate 604 and in contact with the curved plate 604. A spring 1 607 is mounted at the bottom of force-bearing rod 1 606. The end of spring 1 607, facing away from force-bearing rod 1 606, is mounted on the inner wall of hydraulic chamber 2 605. A hose 1 608 is mounted at the bottom of hydraulic chamber 2 605. When curved plate 604 rotates and extends, it squeezes force-bearing rod 1 606 and drives it downward. This, coupled with hydraulic chamber 2 605, which is slidably connected to force-bearing rod 1 606 via the piston, causes the oil within hydraulic chamber 2 605 to flow due to the squeezing of force-bearing rod 1 606. Some of the oil in hydraulic chamber 2 605 then flows into hose 1 608, which is connected to hydraulic chamber 2 605.

[0023] The bottom of the asphalt placement platform 300 is equipped with a hydraulic chamber 3 609, the top of which is slidably connected to a push rod 610 via a piston. When oil flows into hose 1 608, the oil originally stored in hose 1 608 flows into hydraulic chamber 3 609. The oil in hydraulic chamber 3 609 is squeezed and flows toward the end near push rod 610, driving push rod 610, which is slidably connected to hydraulic chamber 3 609 via a piston, to move upward. Push rod 610 then compresses force plate 612 and applies additional force to the asphalt placement platform 300 via spring 2 611, further increasing the pressure between the asphalt sample and the rotating roller 500. This improves the device's support for the asphalt bottom and enhances the accuracy of the test results.

[0024] After the detection operation is completed, when the rotating roller 500 stops rotating, the sliding block 603 loses the effect of centrifugal force and can be reset under the action of the elastic telescopic rod 602. Similarly, the curved plate 604 is reset. When the force-bearing rod 1 606 loses the effect of the curved plate 604, it can be reset under the action of the spring 1 607. Similarly, the push rod 610 is reset.

[0025] When in use, the asphalt sample to be tested is placed on the asphalt placing table 300, the asphalt placing table 300 is activated, the asphalt sample is moved to the bottom position of the rotating roller 500, the rotating roller 500 driven by the servo motor is activated to rotate rapidly on the asphalt sample, and the detection sensor 200 is used to perform corresponding detection operations; at this time, the rapidly rotating rotating roller 500 drives the hydraulic chamber 1 601 connected to it to rotate rapidly, so that the sliding block 603 in the hydraulic chamber 1 601 is stretched under the action of centrifugal force. The telescopic rod 602 moves along the inner wall of the hydraulic chamber 1 601, thereby squeezing the oil originally stored in the hydraulic chamber 1 601, causing the oil to flow to the end close to the curved plate 604, driving the curved plate 604, which is connected to the hydraulic chamber 1 601 by a piston sliding connection, to extend from the hydraulic chamber 1 601. The curved plate 604 extends synchronously when rotating, thereby squeezing the stress rod 1 606 and driving the stress rod 1 606 to move downward, cooperating with the hydraulic chamber 2 605, which is connected to the stress rod 1 606 by a piston sliding connection. , so that the oil in the hydraulic tank 2 605 is squeezed by the force rod 1 606 and flows, and part of the oil in the hydraulic tank 2 605 flows into the hose 1 608 connected to the hydraulic tank 2 605, so that the oil originally stored in the hose 1 608 flows into the hydraulic tank 3 609, and the oil in the hydraulic tank 3 609 is squeezed and flows toward the end close to the push rod 610, which drives the push rod 610, which is connected to the hydraulic tank 3 609 by a piston sliding connection, to move upward, and the push rod 610 then squeezes the force plate 612, And an additional force is applied to the asphalt placing table 300 through spring 2 611, thereby further increasing the pressure between the asphalt sample and the rotating roller 500; after the detection operation is completed, when the rotating roller 500 stops rotating, the sliding block 603 loses the effect of centrifugal force and can be reset under the action of the elastic telescopic rod 602. Similarly, the arc plate 604 is reset, and the force-bearing rod 1 606 loses the effect of the arc plate 604 and can be reset under the action of spring 1 607. Similarly, the top rod 610 is reset.

The side of the hydraulic chamber one 601 is connected to the cam 703 in a transmission manner. The side of the hydraulic chamber four 702 is also connected to the force rod two 704 through the setting of a piston sliding connection. The force rod two 704 is located on the side of the cam 703, and the force rod two 704 and the cam 703 are in contact with each other. When the hydraulic tank 1 601 rotates rapidly, the cam 703 connected to the hydraulic tank 1 601 rotates rapidly therewith. When the protruding part of the cam 703 rotates to the force-bearing rod 2 704, it can squeeze the force-bearing rod 2 704 and drive the force-bearing rod 2 704 to move a certain distance to the side. During the movement, the force-bearing rod 2 704 can squeeze the oil in the hydraulic tank 4 702 that is slidably connected to it by a piston. The oil originally stored in the hydraulic tank 4 702 is squeezed and flows.

[0027] The side of the force-bearing rod 2 704 is equipped with a spring 3 705, the top of the hydraulic chamber 4 702 is equipped with a hose 2 706, the side of the coolant pipe 701 is equipped with a hydraulic chamber 5 707, the side of the hydraulic chamber 5 707 is connected to the connecting rod 1 708 by setting a piston sliding, the bottom of the coolant pipe 701 is rotatably connected to the pipe joint 709, the pipe joint 709 is located on the side of the connecting rod 1 708, and is in a fixed state with the connecting rod 1 708, and the bottom of the pipe joint 709 is equipped with a nozzle 710. When the oil originally stored in the hydraulic tank four 702 is squeezed and flows, part of the oil immediately flows into the hose two 706 connected to it, so that part of the oil in the hose two 706 flows into the hydraulic tank five 707, driving the connecting rod one 708 connected to the hydraulic tank five 707 by a piston sliding connection, and when the protruding part of the cam 703 continues to rotate away from the force-bearing rod two 704, the force-bearing rod two 704 can be reset under the action of the spring three 705. Similarly, the connecting rod one 708 is reset. At this time, the connecting rod one 708 can drive the pipe joint 709 fixed to it to rotate back and forth, and the pipe joint 709 then drives the nozzle 710 installed at its bottom to rotate back and forth, and the coolant injected through the coolant pipe 701 is rotated and sprayed out, thereby increasing the coverage of the coolant for the asphalt sample, thereby improving the cooling efficiency of the device for the asphalt sample.

[0028] When in use, based on the first embodiment, when the hydraulic tank 1 601 rotates rapidly, the cam 703 connected to the hydraulic tank 1 601 rotates rapidly therewith. When the protruding part of the cam 703 rotates to the force rod 2 704, the force rod 2 704 can be squeezed and driven to move a certain distance to the side. During the movement, the force rod 2 704 can squeeze the oil in the hydraulic tank 4 702 which is connected to it by sliding the piston. The oil originally stored in the hydraulic tank 4 702 is squeezed and flows, and part of the oil flows into the hose 2 706 connected to it, so that the hose Part of the oil in the second 706 flows into the hydraulic tank five 707, driving the connecting rod one 708 that is slidably connected to the hydraulic tank five 707 through a piston to move. When the protruding part of the cam 703 continues to rotate and moves away from the force-bearing rod two 704, the force-bearing rod two 704 can be reset under the action of the spring three 705. Similarly, the connecting rod one 708 is reset. At this time, the connecting rod one 708 can drive the pipe joint 709 fixed to it to rotate back and forth, and the pipe joint 709 then drives the nozzle 710 installed at its bottom to rotate back and forth, and the coolant injected through the coolant pipe 701 is rotated and sprayed out.

[0029] For example three, please refer to Figures 1-8 Based on the first and second embodiments, an exhaust gas extraction assembly 800 is installed on the side of the inspection chamber 100. The exhaust gas extraction assembly 800 includes a hose 3 801 mounted on the side of the second hydraulic chamber 605 and an exhaust pipe 802 that runs through the inspection chamber 100 and is connected to the exhaust pump. A sixth hydraulic chamber 803 is mounted on the top of the exhaust pipe 802. The end of the hose 3 801, away from the second hydraulic chamber 605, is mounted on the side of the sixth hydraulic chamber 803. When the oil in the second hydraulic chamber 605 is squeezed and flows, some of the oil flows into the connected hose 3 801, causing the oil originally stored in the hose 3 801 to flow into the connected hydraulic chamber 6 803, squeezing the oil in the sixth hydraulic chamber 803.

Rotating rod 805 is located on the side of connecting rod 2 804 and is fixed to connecting rod 2 804. A blocking block 806 is fixedly connected to the bottom of rotating rod 805. When the oil in hydraulic chamber 6 803 is squeezed, it flows toward the side near connecting rod 2 804. Connecting rod 2 804 then drives rotating rod 805, which is fixed to it, to rotate. This causes rotating rod 805 to rotate blocking block 806, opening air extraction pipe 802, which was originally closed by blocking block 806. At this point, the irritating gas generated by the asphalt sample in the testing chamber 100 can be extracted and processed by the air extraction pump connected to the air extraction pipe 802, reducing the impact of the irritating gas on the device operator and making the device easier to use.

[0031] During use, based on Example 1 and Example 2, when the oil in the hydraulic chamber 2 605 is squeezed and flows, part of the oil immediately flows into the hose 3 801 connected thereto, causing the oil originally stored in the hose 3 801 to flow into the hydraulic chamber 6 803 connected thereto, squeezing the oil in the hydraulic chamber 6 803, causing the oil in the hydraulic chamber 6 803 to flow toward the side close to the connecting rod 2 804, and the connecting rod 2 804 then drives the rotating rod 805 fixedly connected thereto to rotate, causing the rotating rod 805 to drive the blocking block 806 fixedly connected thereto to rotate, thereby converting the exhaust pipe 802 originally closed by the blocking block 806 into an open state. At this time, the irritating gas generated by the asphalt sample in the detection chamber 100 can be extracted and processed by the exhaust pump connected to the exhaust pipe 802.
