Description

Technical Field

[0001] The present invention relates to the technical field of asphalt concrete paving, and more specifically, to an asphalt concrete paving device with horizontal detection and anti-tilting function. Background Art

[0002] An asphalt concrete pavement refers to a pavement with an asphalt concrete surface layer; a mixture prepared by artificially selecting mineral materials with a certain gradation composition and a certain proportion of road asphalt materials under strict control conditions, and using an asphalt concrete paving device to spread the asphalt mixture on the road base and perform preliminary compaction and leveling. However, the existing asphalt concrete paving devices have the following deficiencies when spreading the asphalt mixture on the road base: the asphalt concrete paving device is supported by four moving wheels at the four corners of the bottom, which easily causes the overall instability of the asphalt concrete paving device and tilting, resulting in uneven spreading of the asphalt mixture on the road base, making the asphalt mixture uneven in height, causing trouble in the compaction and leveling process, increasing the workload of later leveling and reducing the paving flatness. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: an asphalt concrete paving device with horizontal detection and anti-tilting function, the structure of which includes a vehicle plate, moving wheels, a controller, height detectors, and electric cylinders. There are four moving wheels, and the four moving wheels are located at the four corners of the bottom of the vehicle plate. There are two controllers, which are respectively fixedly installed on the left and right sides of the upper end surface of the vehicle plate. There are four height detectors, and the four height detectors penetrate and are fixed inside the left and right sides of the vehicle plate. One controller is electrically connected to two height detectors respectively. There are four electric cylinders, and the four electric cylinders are respectively fixed at the four corners of the upper end surface of the vehicle plate. One controller controls the operation of two electric cylinders on the same side respectively. The output end of the electric cylinder is welded with a lifting elastic rod, and the lifting elastic rod is in clearance fit and penetrates through the inside of the limiting plate. The upper end of the spring arranged outside the lower end of the lifting elastic rod is traction-fixed by the limiting plate. The limiting plate is fixedly installed inside the vehicle plate. The bottom of the lifting elastic rod is provided with a hinge plate. The moving wheel is installed inside the hinge plate and is axially connected. The four height detectors arranged at the left and right ends of the vehicle plate perform height detection synchronously, and transmit the detected height data to the two controllers. The two controllers control the corresponding four electric cylinders to expand and contract at the four corners of the vehicle plate. When a single electric cylinder expands and contracts independently, it drives the lifting elastic rod to rise and fall.

[0004] As a further improvement of the present invention, a fabric box is provided on the upper surface of the left end of the vehicle board, and a filler hopper is fixedly installed on the upper end of the fabric box. A guide plate is fixedly installed inside the fabric box, and a motor is fixedly installed outside the fabric box. The output end of the motor is welded with a screw rod to rotate synchronously. The screw rod penetrates into the fabric box and a bearing is provided at the connection. The screw rod is located below the guide plate. A base is provided at the bottom of the fabric box, and a diversion plate is installed on the upper end of the base. The diversion plate is located inside the lower end of the fabric box to divert the asphalt mixture downward. The screw rod is horizontally arranged inside the fabric box. When the asphalt mixture enters the fabric box, under the diversion of the guide plate, all the asphalt mixture passes through the screw rod for screw conveying and spreading.

[0005] As a further improvement of the present invention, a pulley is also provided at the right end of the screw rod. There are two pulleys, and the two pulleys are transmitted through a belt. The other pulley is fixed at the end of the roller shaft inside the vehicle board. The roller is located directly below the screw rod. While the screw rod performs screw conveying and spreading on the asphalt mixture, under the transmission of the two pulleys and the belt, the roller rotates synchronously inside the blanking port of the vehicle board.

[0006] As a further improvement of the present invention, a screed is fixedly installed in the middle of the vehicle board. A knob is installed on the upper end of the screed, and a worm is welded in the middle of the bottom surface of the knob. The worm penetrates through the slider by means of clearance fit, and a guide post penetrates through the side end of the slider by means of clearance fit. The upper end of the guide post is fixedly welded to the upper surface inside the screed. A lower push plate is also provided at the lower end of the slider, and a hinged long plate is connected to the middle of the bottom of the lower push plate. A screed plate is provided at the lower end of the hinged long plate and is axially connected. There are two knobs, worms, and sliders, and they are installed on both sides of the upper end of the push plate. By rotating the two knobs, the heights on both sides of the push plate can be adjusted.

[0007] As a further improvement of the present invention, an elastic traction plate is also provided at the connection between the screed plate and the rear end of the hinged long plate. An elastic traction is applied to the screed plate through the elastic traction plate to ensure that the front and rear of the screed plate are in an inclined state to level the asphalt mixture.

[0008] As a further improvement of the present invention, a leveling device is also provided at the right end of the vehicle board. An air pump is fixedly installed on the upper end of the leveling device, and the air pump is connected in communication with an adapter provided in the middle of the upper end of the leveling device. The adapter is connected in communication with a pneumatic vibrator provided inside the leveling device. A vibration plate is fixedly installed at the bottom of the pneumatic vibrator. A connecting column is welded to the lower end of the vibration plate, and a leveling plate is welded to the lower end of the connecting column. There are two connecting columns, and they are symmetrically installed on the left and right between the vibration plate and the leveling plate. By sending air pressure into the pneumatic vibrator through the air pump, the pneumatic vibrator generates vibration.

[0009] As a further improvement of the present invention, a screed plate is further provided at the bottom of the screed, and the screed plate is electrically connected to a heating box installed at the upper end of the leveling device. While the screed plate is driven by the screed to vibrate, the heating box transfers heat to the screed plate, thereby vibrating and compacting the asphalt by ironing.

[0010] The beneficial effects of the present invention are as follows: 1. Four height detectors perform height detection synchronously, and transmit the detected height data to the interiors of two controllers. The two controllers control the corresponding four electric cylinders to expand and contract at the four corners of the vehicle board. When a single electric cylinder expands and contracts independently, it drives the lifting elastic rod to lift and lower. At this time, the hinge plate at the bottom can adjust the lifting of the moving wheels. By adjusting the lifting of the four moving wheels at the four corners of the bottom of the vehicle board, the entire vehicle board is automatically leveled to be parallel to the paved road surface, avoiding tilting during the paving process. 2. The asphalt mixture is put into the cloth box from the filler hopper and under the diversion of the guide plate, so that the asphalt mixture all passes through the screw rod for threaded conveying and cloth laying, and is guided downward and discharged through the two guide plates at the bottom. While the screw rod rotates, under the transmission of two belt pulleys and a belt, the rollers rotate synchronously inside the discharge opening of the vehicle board, and can roll the asphalt mixture again during the discharging process to ensure that the asphalt mixture can be stably and horizontally evenly laid on the road surface, avoiding the situation of uneven height on the left and right sides of the paved asphalt mixture on the road surface. 3. Elastic traction is applied to the scraping plate through the elastic traction plate to ensure that the front and rear of the scraping plate are inclined to scrape the asphalt mixture. After scraping, the vibration plate is driven to vibrate by the pneumatic vibrator at the rear end, and the vibration is transmitted to the screed plate through the connecting column. At the same time, the screed plate is heated. The asphalt is vibrated and heated by the screed plate to vibrate and iron the asphalt to be compacted, so that the asphalt achieves a better leveling effect. Description of the Drawings

Specific embodiments

[0019] The following further describes the present invention with reference to the accompanying drawings: Embodiment

[0020] As shown in Figure 1 to Figure 5 shown: An asphalt concrete paving device with horizontal detection and anti - tilt of the present invention, its structure includes a vehicle board 1, moving wheels 2, a controller 3, height detectors 4, and electric cylinders 5. Four moving wheels 2 are provided, and the four moving wheels 2 are located at the four corners of the bottom of the vehicle board 1. Two controllers 3 are provided and are respectively fixedly installed on the left and right sides of the upper end surface of the vehicle board 1. Four height detectors 4 are provided and the four height detectors 4 penetrate and are fixed inside the left and right sides of the vehicle board 1. One controller 3 is electrically connected to two height detectors 4 respectively. Four electric cylinders 5 are provided and the four electric cylinders 5 are respectively fixed at the four corners of the upper end surface of the vehicle board 1. One controller 3 controls the operation of two electric cylinders 5 on the same side respectively. The output end of the electric cylinder 5 is welded with a lifting elastic rod 51, and the lifting elastic rod 51 is in clearance fit and penetrates through the inside of the limiting plate 52. The upper end of the spring arranged outside the lower end of the lifting elastic rod 51 is traction - fixed by the limiting plate 52. The limiting plate 52 is fixedly installed inside the vehicle board 1. The bottom of the lifting elastic rod 51 is provided with a hinged plate 53. The moving wheel 2 is installed inside the hinged plate 53 and is axially connected.

[0021] As a further improvement of the present invention, a cloth box 6 is provided on the upper surface of the left end of the vehicle board 1, and a filling hopper 61 is fixedly installed on the upper end of the cloth box 6. A guiding plate 62 is fixedly installed inside the cloth box 6, and a motor 63 is fixedly installed outside the cloth box 6. The output end of the motor 63 is welded with a screw rod 64 to rotate synchronously. The screw rod 64 penetrates inside the cloth box 6 and a bearing 641 is provided at the connection. The screw rod 64 is located below the guiding plate 62. A base 65 is provided at the bottom of the cloth box 6, and a diversion plate 66 is installed on the upper end of the base 65. The diversion plate 66 is located inside the lower end of the cloth box 6 to divert the asphalt mixture downward.

[0022] As a further improvement of the present invention, a pulley 642 is further provided at the right end of the screw rod 64. There are two pulleys 642, and the two pulleys 642 are transmitted through a belt 643. The other pulley 642 is fixed to the shaft end of a roller 644 inside the vehicle board 1; In the present invention, the vehicle board 1 is placed on the paved road surface. At this time, the four height detectors 4 work synchronously to detect the heights of the four corners of the vehicle board 1 on the paved road surface. The detected data is transmitted to the inside of the controller 3. The height detection data obtained by the four height detectors 4 can clearly understand the height difference at which angle the vehicle board 1 is placed on the paved road surface. Thus, the controller 3 controls the electric cylinder 5 at the corresponding lower position to start, driving the lifting elastic rod 51 to extend. At this time, the hinged plate 53 drives the moving wheel 2 to descend, thereby adjusting the height of one corner of the vehicle board 1 at the lower position. After adjusting to the same height detected by the four height detectors 4, the vehicle board 1 is in a parallel state with the paved road surface, avoiding tilting during the paving process. Then, the asphalt mixture is put into the cloth box 6 from the filling hopper 61. Under the diversion of the guiding plate 62, all the asphalt mixture passes through the screw rod 64 for screw conveying and cloth laying, and is guided downward and discharged through the two diversion plates 66 at the bottom. While the screw rod 64 rotates, under the transmission of the two pulleys 642 and the belt 643, the roller 644 rotates synchronously inside the discharge port of the vehicle board 1, and can roll the asphalt mixture again during the discharging process, ensuring that the asphalt mixture can be stably and horizontally evenly laid on the road surface, avoiding the situation of uneven height on the left and right sides of the paved asphalt mixture on the road surface.

[0023] In a preferred technical solution, four height detectors 4 provided at the left and right ends of the vehicle board 1 perform height detection synchronously, and transmit the detected height data to the inside of two controllers 3. The two controllers 3 control the corresponding four electric cylinders 5 to expand and contract at the four corners of the vehicle board 1. When a single electric cylinder 5 expands and contracts independently, it drives the lifting elastic rod 51 to rise and fall. At this time, the hinge plate 53 at the bottom can adjust the height of the moving wheel 2. By adjusting the height of the four moving wheels 2 at the four corners of the bottom of the vehicle board 1, the whole vehicle board 1 can be automatically leveled to be parallel to the paved road surface, avoiding the situation of inclination during the paving process; In a preferred technical solution, the screw rod 64 is horizontally arranged inside the cloth box 6. When the asphalt mixture enters the inside of the cloth box 6, under the diversion of the guide plate 62, all the asphalt mixture passes through the screw rod 64 for screw conveying and cloth laying, and is guided downward and discharged through the two diversion plates 66 at the bottom, so that the transverse cloth laying of the asphalt mixture is more uniform and can be evenly discharged onto the paved road surface; In a preferred technical solution, the roller 644 is located directly below the screw rod 64. While the screw rod 64 performs screw conveying and cloth laying on the asphalt mixture, under the transmission of two belt wheels 642 and a belt 643, the roller 644 rotates synchronously inside the discharge port of the vehicle board 1, and can roll the asphalt mixture again during the discharging process to ensure that the asphalt mixture can be stably and horizontally evenly laid on the road surface, avoiding the situation of uneven height on the left and right sides of the paved asphalt mixture on the road surface. Embodiment 2: On the basis of Embodiment 1, as shown in the attached Figure 6 to the attached Figure 7 figure: A leveling device 7 is also fixedly installed in the middle of the vehicle board 1. A knob 71 is installed at the upper end of the leveling device 7, and a worm 72 is welded in the middle of the bottom surface of the knob 71. The worm 72 passes through the inside of the slider 73 by means of clearance fit, and a guide post 731 passes through the side end inside of the slider 73 by means of clearance fit. The upper end of the guide post 731 is fixedly welded on the inner upper surface of the leveling device 7. A lower pushing plate 74 is also provided at the lower end of the slider 73, and a hinged long plate 75 is connected to the middle end of the bottom of the lower pushing plate 74. A scraping plate 76 is provided at the lower end of the hinged long plate 75 and is axially connected.

[0024] As a further improvement of the present invention, an elastic traction plate 77 is also provided at the connection between the scraping plate 76 and the rear end of the hinged long plate 75. By applying elastic traction to the scraping plate 76 through the elastic traction plate 77, it is ensured that the front and rear of the scraping plate 76 are in an inclined state to scrape the asphalt mixture flat.

[0025] As a further improvement of the present invention, a leveling device 8 is further provided at the right end of the vehicle board 1. An air pump 81 is fixedly installed at the upper end of the leveling device 8, and the air pump 81 is connected in through connection with a connection head 82 provided in the middle of the upper end of the leveling device 8. The connection head 82 is connected in through connection with a pneumatic vibrator 83 provided inside the leveling device 8. A vibrating plate 84 is fixedly installed at the bottom of the pneumatic vibrator 83. A connecting column 85 is welded to the lower end of the vibrating plate 84, and a leveling plate 86 is welded to the lower end of the connecting column 85.

[0026] As a further improvement of the present invention, an ironing plate 861 is further provided at the bottom of the leveling plate 86, and the ironing plate 861 is electrically connected to a heating box 862 installed at the upper end of the leveling device 8. While the leveling plate 86 drives the ironing plate 861 to vibrate, the heating box 862 transfers heat to the ironing plate 861, thereby vibrating and ironing and compacting the asphalt, so that the asphalt achieves a better leveling effect. In the present invention, before laying the asphalt mixture, it is also necessary to drive the worm 72 to rotate by rotating two knobs 71, so that the slider 73 is adjusted up and down on the worm 72. The heights on both sides of the push plate 74 are adjusted by the sliders 73 on both sides, so as to adjust the heights of both ends of the articulated long plate 75 and the scraping plate 76, ensuring that the scraping plate 76 can be kept parallel to the paved road surface. After the asphalt mixture is laid on the road surface, the movement of the vehicle board 1 drives the scraping plate 76 to move. At this time, the scraping plate 76 initially scrapes the asphalt mixture laid on the road surface. And during the scraping process, an elastic traction is applied to the scraping plate 76 through the elastic traction plate 77, ensuring that the front and back of the scraping plate 76 are in an inclined state to scrape the asphalt mixture. After scraping, the pneumatic vibrator 83 at the rear end continues to drive the vibrating plate 84 to vibrate, and the vibration is transmitted to the leveling plate 86 through the connecting column 85. At the same time, the ironing plate 861 is heated, and the asphalt is vibrated and heated through the ironing plate 861, vibrating and ironing and compacting the asphalt, so that the asphalt achieves a better leveling effect.

[0027] In a preferred technical solution, there are two knobs 71, worms 72, and sliders 73, and they are installed on both sides of the upper end of the push plate 74. By rotating the two knobs 71, the heights on both sides of the push plate 74 can be adjusted, so as to adjust the heights of both ends of the articulated long plate 75 and the scraping plate 76, ensuring that the scraping plate 76 can be kept parallel to the paved road surface, so that the asphalt mixture laid on the road surface later can be scraped flat. In a preferred technical solution, there are two connecting columns 85, and they are symmetrically installed on the left and right between the vibrating plate 84 and the leveling plate 86. The air pressure is conveyed into the pneumatic vibrator 83 through the air pump 81, so that the pneumatic vibrator 83 generates vibration. At this time, the vibrating plate 84 drives the leveling plate 86 to vibrate, so that the leveling plate 86 vibrates and levels the asphalt mixture on the road surface. Any technical solution using the technical solution of the present invention or designed by those skilled in the art inspired by the technical solution of the present invention and achieving the above technical effects shall fall within the protection scope of the present invention.
