[0033] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0034] Please refer to Figures 1 to 5 , the embodiments provided by the present utility model are:

[0035] A paver for an airport concrete runway comprises a platform assembly 1 and a travel assembly 2. The platform assembly 1 includes a standing platform 11, platform columns 12, and guardrails 13. The travel assembly 2 includes symmetrically arranged left and right travel mechanisms 21 and 22. The length of the standing platform 11 is greater than the concrete paving width, allowing the paver to pave the entire width of the airport runway in one pass. This not only improves the runway flatness but also enhances work efficiency. The lower left side of the standing platform 11 is fixedly connected to the left travel mechanism 21 via the platform column 12, and the lower right side of the standing platform 11 is fixedly connected to the right travel mechanism 22 via the platform column 12. The platform column 12 distances the standing platform 11 from the ground, facilitating the pouring of cement below the standing platform 11. The guardrails 13 are vertically arranged at the edge of the standing platform 11. During operation, a person can stand on or off the standing platform 11, and the paver can simply move forward.

[0036] In order to facilitate people to get on and off the standing platform 11, the platform assembly 1 also includes a ladder 14. There are two ladders 14, whose upper ends are respectively suspended on the left and right sides of the standing platform 11. People can get on and off from the ladder 14 on the left or right side of the standing platform 11.

[0037] In order to ensure a stable connection between the platform column 12 and the walking assembly 2, the platform assembly 1 further includes a connecting frame 15, which includes a horizontal top plate 151 and two vertical L-plates 152. The two vertical L-plates 152 are symmetrically arranged relative to each other, and the tops of the two vertical L-plates 152 are fixedly connected to the horizontal top plate 151, and the bottoms of the two vertical L-plates 152 are fixedly connected to the walking assembly 2. For details, refer to the attached Figure 1 and attached Figure 2 As shown, the bottom of the vertical L-plate 152 is fixedly connected to the side of the left walking mechanism 21 or the right walking mechanism 22, and the horizontal top plate 151 is fixedly connected to the bottom of the platform column 12, stably connecting the platform column 12 and the walking component 2.

[0038] Furthermore, the left traveling mechanism 21 and the right traveling mechanism 22 are both wheeled traveling mechanisms or crawler-type traveling mechanisms. The wheeled traveling mechanism has good flexibility, and the crawler-type traveling mechanism has good stability.

[0039] In order to facilitate the control of the paver, please refer to Figure 1 and Figure 2 As shown, the machine further includes a control assembly 5, comprising a console 51 and a generator 52. The console 51 is mounted on the standing platform 11 and electrically connected to the travel assembly 2. The console 51 is also electrically connected to the generator 52, with the generator 52 providing power to the console 51, which controls the movement of the travel assembly 2. A switch for the console 51 can be provided on the console 51, allowing a user to turn the paver on and off while standing on the standing platform 11. Alternatively, a remote control device can be connected to the console 51, allowing the console 51 to be turned on and off remotely without requiring a user to stand on the standing platform 11.

[0040] In order to provide a more stable power source for the paver, a solar module 6 is further included. The solar module 6 includes a roof, a shed frame 61, a solar panel 62, a solar controller, and a battery. The roof is fixed to the standing platform 11 via the shed frame 61. The solar panel 62 is fixed to the top surface of the roof. The solar panel 62 is electrically connected to the solar controller, which is also electrically connected to the input end of the battery. The output end of the battery is electrically connected to the console 51. By adding a roof above the standing platform 11, on the one hand, it has the function of shielding from rain and sun, and on the other hand, it is convenient to add the solar panel 62, so that the console 51 can be powered by the sun, wherein the solar controller and battery are fixed to the standing platform 11.

[0041] To enable the paver to have automatic leveling function, please refer to Figures 1 to 4As shown, the trowel assembly 3 is also included. The trowel assembly 3 includes a front mounting frame 31, a front robotic arm sliding assembly 32, a front manipulator 33, and a trowel head 34. The front mounting frame 31 is fixed to the front top surface of the standing platform 11. The fixed end of the front robotic arm sliding assembly 32 is fixed to the front side surface of the front mounting frame 31. The front manipulator 33 is fixed to the sliding end of the front robotic arm sliding assembly 32. The trowel head 34 is fixed to the front end of the front manipulator 33, and the working surface of the trowel head 34 is set downward. The front robotic arm sliding assembly 32 drives the front manipulator 33 to slide left and right in the horizontal direction, thereby achieving troweling operations within the entire paving width of the airport runway using the front manipulator 33 to drive the trowel head 34. Specifically, the number of front manipulators 33 is one or more, and is selected according to the operation conditions. If multiple front manipulators 33 are used, on-site operation efficiency can be improved.

[0042] Since the road outside the airport runway is uneven, in order to ensure the flatness of the runway after the front manipulator 33 drives the leveling head 34 to operate, the leveling component 3 further includes a left front ranging sensor 35 and a right front ranging sensor 36. The left front ranging sensor 35 is fixed to the left front position of the lower surface of the standing platform 11, and the right front ranging sensor 36 is fixed to the right front position of the lower surface of the standing platform 11. In the overhead direction, the left front ranging sensor 35 and the right front ranging sensor 36 are within the concrete paving width range. During the construction process, the walking component 2 drives the standing platform 11 to move straight forward, and the left front ranging sensor 35 and the right front ranging sensor 36 measure the distance within the cement paving width. The left front ranging sensor 35 faces downward to detect the height of the left front of the standing platform 11 of the paver from the cement surface. The right front ranging sensor 36 faces downward to detect the height of the right front of the standing platform 11 of the paver from the cement surface. The inclination angle of the standing platform 11 is calculated based on the height difference between the two, so as to adjust the height and angle of the operation of the leveling head 34 driven by the front manipulator 33 in real time, so as to realize the precise leveling operation of the airport cement runway.

[0043] Specifically, the left front distance measuring sensors 35 are ultrasonic sensors, numbering 1 to 3; the right front distance measuring sensors 36 are ultrasonic sensors, numbering 1 to 3. The height distances detected by the left and right front distance measuring sensors 35 and 36 are used to calculate the actual operating plane of the trowel head 34, allowing the front manipulator 33 to be adjusted to the appropriate height and angle for operation.

[0044] Since the airport runway needs to be leveled when the cement is initially laid, please refer to Figure 3As shown, the trowel assembly 3 further includes an initial distance measuring sensor group, which includes a plurality of initial distance measuring sensors 37 arranged side by side in the front-to-back direction. The initial distance measuring sensor group is fixed to the lower surface of the sliding end of the front manipulator sliding assembly 32. Specifically, the initial distance measuring sensor group can move left and right under the drive of the front manipulator sliding assembly 32, and the detection surface of the initial distance measuring sensors 37 faces downward. After the initial distance measuring sensor group moves once in the horizontal direction along with the front manipulator sliding assembly 32, the plurality of initial distance measuring sensors 37 return the height values ​​of a corresponding number of straight lines. Based on these height values, a suitable trowel surface, i.e., the initial leveling surface, is calculated. Then, concrete cement is poured, and the trowel head 34 is driven by the front manipulator 33 to start the troweling operation.

[0045] In order to make the paver have the automatic roughening function, please refer to Figure 5 As shown, it also includes a roughening component 4, which includes a rear mounting frame 41, a rear robotic arm sliding assembly 42, a rear manipulator 43 and a roughening head 44. The rear mounting frame 41 is fixed to the top surface of the rear side of the standing platform 11, the fixed end of the rear robotic arm sliding assembly 42 is fixed to the rear side surface of the rear mounting frame 41, the rear manipulator 43 is fixed to the sliding end of the rear robotic arm sliding assembly 42, and the roughening head 44 is fixed to the front end of the rear manipulator 43, with the working surface of the roughening head 44 facing downward. During operation, the rear robotic arm sliding assembly 42 drives the rear manipulator 43 to slide left and right in the horizontal direction, thereby achieving roughening operations within the entire paving width of the airport runway with the rear manipulator 43 driving the roughening head 44. Specifically, the number of the rear manipulators 43 is one or more, which is selected according to the operation conditions. If multiple rear manipulators 43 are used, the efficiency of on-site operations can be improved.

[0046] Since the road outside the airport runway is uneven, in order to ensure the flatness of the runway after the rear manipulator 43 drives the roughening head 44 to operate, the roughening component 4 further includes a left rear ranging sensor 45 and a right rear ranging sensor 46. The left rear ranging sensor 45 is fixed on the left rear position of the lower surface of the standing platform 11, and the right rear ranging sensor 46 is fixed on the right rear position of the lower surface of the standing platform 11. In the overhead direction, the left rear ranging sensor 45 and the right rear ranging sensor 46 are within the concrete paving width range. During the construction process, the walking component 2 drives the standing platform 11 to move straight forward, and the left rear ranging sensor 45 and the right rear ranging sensor 46 measure the distance within the cement paving width. The left rear ranging sensor 45 faces downward to detect the height of the left rear side of the standing platform 11 of the paver from the cement surface. The right rear ranging sensor 46 faces downward to detect the height of the right rear side of the standing platform 11 of the paver from the cement surface. The inclination angle of the standing platform 11 is calculated based on the height difference between the two, and thus the smoothed cement surface of the roughening head 44 in the operating area is calculated, and the height and angle of the roughening head 44 to be driven by the rear manipulator 43 are adjusted in real time to achieve precise smoothing operations on the airport cement runway.

[0047] For further details on the specific structures of the front robotic arm sliding assembly 32 and the rear robotic arm sliding assembly 42, please refer to Figure 4 As shown, the front robotic arm sliding assembly 32 and the rear robotic arm sliding assembly 42 have the same structure, including a slide rail 321, a sliding block 322, a rack 323, a gear, and a motor 324. The slide rail 321 and the sliding block 322 slide in cooperation with each other. The slide rail 321 and the rack 323 are both horizontally arranged. The gear meshes with the rack 323, and the gear is driven to rotate by the motor 324, which is fixed to the sliding block 322. During operation, the motor 324 rotates to drive the gear to rotate, and the gear rotates and moves left and right along the rack 323, thereby achieving left and right sliding of the sliding block 322 relative to the slide rail 321 in the horizontal direction, and the structure has good stability.

[0048] Specifically, the rack 323 and the slide rail 321 are the fixed ends of the front robotic arm sliding assembly 32, and the sliding block 322 is the sliding end of the front robotic arm sliding assembly 32. Similarly, the rack 323 and the slide rail 321 are the fixed ends of the rear robotic arm sliding assembly 42, and the sliding block 322 is the sliding end of the rear robotic arm sliding assembly 42.

[0049] Furthermore, the front manipulator 33 and the rear manipulator 43 have the same structure and are six-axis manipulators, which can ensure the movement and swing of the smoothing head 34 and the roughening head 44 within a spatial range.

[0050] In order to prevent dust from entering the front robotic arm sliding assembly 32 and the rear robotic arm sliding assembly 42, the front robotic arm sliding assembly 32 and the rear robotic arm sliding assembly 42 further include an accordion cover 325, and the accordion cover 325 covers the outside of the slide rail 321 and the rack 323, and the accordion cover 325 is divided into two sections, which are respectively arranged on the left and right sides of the sliding block 322, and have a good dust-proof effect.

[0051] Furthermore, the trowel assembly 3 further includes a front baffle 38, which is fixed to the top of the front mounting frame 31 and extends forward. The roughening assembly 4 further includes a rear baffle 47, which is fixed to the top of the rear mounting frame 41 and extends backward to prevent stones from damaging the trowel assembly 3 or the roughening assembly 4.

[0052] Furthermore, the console 51 is also electrically connected to the smoothing component 3 and the roughening component 4 , and the automatic operation of the smoothing component 3 and the roughening component 4 is controlled by the console 51 .

[0053] For the airport concrete runway paver mentioned above, assuming that the roughening length and smoothing length are the same each time the paver moves forward, its specific working process is as follows:

[0054] Preparatory work: Preset the paving baffles on both sides of the airport runway, start the control console 51, drive the paver to the appropriate position and angle, and stop the travel assembly 2;

[0055] Initial measurement: The front robot arm sliding assembly 32 drives the initial distance measuring sensor group to move horizontally from left to right or from right to left by one working width, and calculates the appropriate initial screed surface based on the height of the initial distance measuring sensors 37 from the current uneven ground detected by multiple initial distance measuring sensors 37;

[0056] Initial paving: pouring concrete cement, the front manipulator 33 drives the trowel head 34 to perform troweling according to the initial trowel surface until the cement in the rectangular area consisting of an operating width and a trowel length is smoothed;

[0057] Forward paving: Start the walking assembly 2 to drive the standing platform 11 to move forward a smoothing length;

[0058] At this time, the left front distance measuring sensor 35 detects the height of the sensor from the leveled position point below it, and the right front distance measuring sensor 36 detects the height of the sensor from the leveled position point below it. The current leveled surface is calculated based on the height values ​​measured by the left front distance measuring sensor 35 and the right front distance measuring sensor 36.

[0059] The front manipulator 33 drives the trowel head 34 to perform the troweling operation according to the current troweling surface until the cement in the rectangular area consisting of an operating width and a troweling length is smoothed;

[0060] Detect whether roughening operation is required. If not, turn to start the walking component 2 to drive the standing platform 11 to move forward a smoothing length to continue execution;

[0061] If yes, the roughening operation is started. At this time, the left rear distance sensor 45 detects the height of the sensor from the smoothed position point below it, and the right rear distance sensor 46 detects the height of the sensor from the smoothed position point below it. The current roughening surface is calculated based on the height values ​​measured by the left rear distance sensor 45 and the right rear distance sensor 46;

[0062] The rear manipulator 43 drives the roughening head 44 to perform roughening operation according to the current roughening surface until the cement in the rectangular area consisting of an operation width and a roughening length is roughened;

[0063] The current smoothing and roughening operations are completed, and the test is performed to see if the runway paving is completed. If not, the process starts with the walking assembly 2, driving the standing platform 11 to move forward a smoothing length.

[0064] If yes, the paver operation is ended.
