[0026] The width limiting component 5 is used to limit the width of the paving component 4. The transverse movement component 3 includes two sliding rods 31, one in front and one behind. Both sliding rods 31 are fixedly connected to the left and right sides of the inner wall of the main support 1. A lead screw 32 is rotatably connected between the left and right sides of the inner wall of the main support 1, and the lead screw 32 is located between the two sliding rods 31.

A drive motor 33 is fixedly connected to the right side of the main support 1. The output end of the drive motor 33 is fixedly connected to one end of the lead screw 32. Two limit switches 34 are fixedly connected to the bottom of the main support 1. When the paving component 4 contacts the limit switch 34, the drive motor 33 is controlled to stop and rotate in the opposite direction.

[0027] The lifting assembly 2 includes two fixed legs 21, one at the front and one at the back. Both fixed legs 21 are fixedly connected to one side of the main support 1. Movable legs 22 are slidably connected to the inner surfaces of both fixed legs 21. Universal wheels 23 are fixedly installed at the bottom of both movable legs 22. An intermediate plate 24 is fixedly connected between the two movable legs 22. A hydraulic cylinder 25 is fixedly connected between the two fixed legs 21 through a connecting plate. The telescopic end of the hydraulic cylinder 25 is fixedly connected to the top of the intermediate plate 24.

[0028] The paving assembly 4 includes a secondary support 41. The bottom of the secondary support 41 is fixedly connected to two sets of bearing seats 42, each set of bearing seats 42 consisting of two bearing seats 42, one in front and one in back. A pressure roller 43 is rotatably connected between each set of bearing seats 42, and one end of the pressure roller 43 is fixedly connected to a first pulley 44. An input motor 45 is fixedly connected to the top of the secondary support 41, and the output end of the input motor 45 is fixedly connected to a second pulley 46. The two first pulleys 44 and the second pulley 46 are connected by belt drive.

[0029] During highway construction, the lateral movement component 3 and the paving component 4 in the device work together to achieve lateral paving of the highway surface, thereby facilitating local paving operations and improving the practicality of the device.

[0030] The width limiting component 5 includes two rotating seats 51, one at the front and one at the back. The two rotating seats 51 are fixedly connected to the bottom of the secondary bracket 41 by bolts. A bidirectional threaded rod 52 is rotatably connected between the two rotating seats 51. Two limiting plates 53 are threadedly connected to the surface of the bidirectional threaded rod 52. An adjusting motor 54 is fixedly connected to the front of the two front rotating seats 51. The output end of the adjusting motor 54 is fixedly connected to one end of the bidirectional threaded rod 52. The limiting plate 53 includes a middle frame 531 and two first arc-shaped rings 532 on the left and right. The two first arc-shaped rings 532 are fixedly connected to the two ends of the middle frame 531 respectively. A second arc-shaped ring 533 is rotatably connected to the opposite side of the two first arc-shaped rings 532. A plug 535 is fixedly connected to the other end of the two second arc-shaped rings 533. A slot 534 that mates with the plug 535 is opened at one end of the two first arc-shaped rings 532. The plug 535 is inserted into the slot 534 and fixed by an internal hex bolt 536.

[0031] When paving is carried out by the pressure roller assembly 4, the width of the construction is controlled by the width limiting component 5 set on the pressure roller assembly 4, thereby ensuring the accuracy of the paving width, and the width limiting component 5 is designed to be detachable.

[0032] In use, move the entire device to the construction area. After the asphalt is delivered into the construction area, start the lifting assembly 2, activate the hydraulic cylinder 25, and move the moving leg 22 to adjust the height of the paving assembly 4 so that the pressure roller 43 contacts the asphalt. Then, start the adjusting motor 54 to rotate the bidirectional threaded rod 52. The rotation of the bidirectional threaded rod 52 causes the two limit plates 53 to move closer or further apart, thereby controlling the width of the asphalt paving. Next, start the drive motor 33 to rotate the screw 32, thereby driving the paving assembly 4 to move laterally. After the paving assembly 4 contacts the limit switch 34, the drive motor 33 stops rotating and rotates in the opposite direction, causing the paving assembly 4 to move in the opposite direction. At the same time, the input motor... When motor 45 is in operation, it starts and drives the second pulley 46 to rotate. The rotation of the second pulley 46 transmits power to the first pulley 44 via belt. The rotation of the first pulley 44 drives the two pressure rollers 43 to rotate, thus completing the paving during the lateral movement. In addition, when the width limiting component 5 is installed, it is fixed to the bottom of the secondary support 41 by bolts, and the second arc ring 533 is rotated so that the hexagonal socket bolt 536 is inserted into the slot 534. At this time, the ring formed by the first arc ring 532 and the second arc ring 533 is fitted on the pressure roller 43, and the hexagonal socket bolt 536 is inserted from the outside of the first arc ring 532 and screwed into the hexagonal socket bolt 536.
