[0027] Concrete pavement paver leveling machines play an important role in road construction. However, the existing paver leveling machines have obvious deficiencies in adapting to different road conditions. During the paving process of traditional equipment, it is often difficult to flexibly cope with the changes in road surface height and inclination. Especially when constructing on complex terrains or special sections, the existing technologies cannot effectively adjust the paving parameters, resulting in unstable paving quality. For example, when the road surface transitions from flat to a steep slope, the equipment is difficult to timely adjust the paving thickness and flatness, causing uneven road surfaces. Similarly, on sections with frequent bends or changing gradients, the adaptability of the existing equipment is insufficient, and it is difficult to ensure the coherence of the paving effect. These problems severely restrict the application scope of paver leveling machines and reduce the construction efficiency and road surface quality.

[0028] Refer to Figures 1 to 3 , the present application provides a concrete pavement paver leveling machine, including a mobile vehicle 100, a paving device 200, and a leveling device 300.

[0029] The paving device 200 includes a lifting platform 210, a lifting drive mechanism 220, a paving drum 230, and a height adjustment mechanism 240. The lifting platform 210 is slidably connected to the mobile vehicle 100. One end of the lifting drive mechanism 220 is connected to the mobile vehicle 100, and the other end is connected to the lifting platform 210. The lifting drive mechanism 220 is used to drive the lifting platform 210 to lift and slide relative to the mobile vehicle 100. The paving drum 230 is located below the lifting platform 210 and extends along the width direction of the lifting platform 210. The paving drum 230 is connected to the lifting platform 210 through the height adjustment mechanism 240. The height adjustment mechanism 240 is used to adjust the height of the paving drum 230 relative to the ground. The leveling device 300 is arranged at the rear side of the paving device 200. The leveling device 300 includes a mounting seat 310, a screed 320, and an inclination adjustment mechanism 330. The mounting seat 310 is connected to the lifting platform 210. The screed 320 extends along the length direction of the paving drum 230. The screed 320 is connected to the mounting seat 310 through the inclination adjustment mechanism 330. The inclination adjustment mechanism 330 is used to adjust the inclination of the screed 320 relative to the ground in the front-rear direction.

[0030] During the working process, the mobile vehicle 100 travels. When the paving drum 230 passes over the concrete pile, it will spread and flatten the concrete so that the concrete is evenly spread on the road surface. Then, the screed 320 of the leveling device 300 will perform a leveling treatment on the concrete surface, thus completing the paving and leveling treatment of the concrete road surface. When the height and inclination of the road surface change, the height of the paving drum 230 is adjusted through the height adjustment mechanism 240 so that the height of the paving drum 230 adapts to the height of the road surface. At the same time, the inclination of the screed 320 relative to the ground is adjusted through the inclination adjustment mechanism 330 so that the inclination of the screed 320 adapts to the inclination of the ground. This paving and leveling machine can realize concrete paving and leveling on road surfaces with different heights and different inclinations, and has a wider adaptation range and higher flexibility during the working process.

[0031] The lifting platform 210 is a rectangular platform. The width of the lifting platform 210 is greater than or equal to the width of the mobile vehicle 100. Sliders are installed on the lifting platform 210, and slide rails are installed on the mobile vehicle 100. The sliders on the lifting platform 210 are slidably matched with the slide rails on the mobile vehicle 100. The paving drum 230 is horizontally arranged below the lifting platform 210. The length of the paving drum 230 is longer than the width of the lifting platform 210. Both ends of the paving drum 230 extend out from both sides of the lifting platform 210. Both ends of the paving drum 230 are connected to the lifting platform 210 through the height adjustment mechanism 240. When adjusting the height of the paving drum 230, the height adjustment mechanisms 240 at both ends of the paving drum 230 work synchronously to adjust the height of the paving drum 230.

[0032] In some embodiments, the paving drum 230 is hinged to the lifting platform 210 at a first hinge point, and the height adjustment mechanism 240 drives the paving drum 230 to rotate around the first hinge point, so as to adjust the height of the paving drum 230.

[0033] Refer to Figure 2 , in some embodiments, the height adjustment mechanism 240 includes a connecting arm 241 and a first driving cylinder 242. One end of the connecting arm 241 is hinged to the lifting platform 210, and the other end is hinged to the end of the paving drum 230. The hinged position of the connecting arm 241 and the lifting platform 210 is the first hinge point. The piston rod of the first driving cylinder 242 is hinged to the middle of the connecting arm 241, and the cylinder body of the first driving cylinder 242 is hinged to the lifting platform 210.

[0034] Specifically, connecting arms 241 are arranged at both ends of the paving drum 230. One end of each connecting arm 241 is hinged to the paving drum 230, and the other end is hinged to the lifting platform 210. There are two first driving cylinders 242, and both of the two first driving cylinders 242 are located at both ends of the paving drum 230. The piston rod of the first driving cylinder 242 is hinged to the middle of the paving drum 230, and the cylinder body of the first driving cylinder 242 is hinged to the side of the lifting platform 210. During the process of lifting the paving drum 230, the first driving cylinder 242 drives the connecting arm 241 to swing through the telescopic movement of the piston rod, and further makes the connecting arm 241 drive the paving drum 230 to lift and adjust relative to the ground.

[0035] Of course, in addition to the above setting method, the height adjustment mechanism 240 can also be set as a hydraulic cylinder. The hydraulic cylinder is vertically arranged, and the piston rod of the hydraulic cylinder is hinged to the paving drum 230 to drive the lifting of the paving drum 230 through the hydraulic cylinder.

[0036] Refer to Figure 3 , in some embodiments, the inclination angle adjustment mechanism 330 includes a connecting rod 331 and a second driving cylinder 332. One end of the connecting rod 331 is fixedly connected to the mounting seat 310, and the other end is hinged to the middle of the screed 320. The second driving cylinder 332 is arranged on one side of the connecting rod 331. The piston rod of the second driving cylinder 332 is hinged to the screed 320, and the cylinder body of the second driving cylinder 332 is hinged to the mounting seat 310.

[0037] Specifically, the length of the screed 320 is the same as that of the paving drum 230. The screed 320 is arranged in parallel with the paving drum 230. The upper end of the connecting rod 331 is fixedly connected to the mounting seat 310, and the lower end of the connecting rod 331 is hinged to the middle of the screed 320 through a rotating shaft. The second driving cylinder 332 is arranged in the middle of one side of the screed 320. During the working process, the inclination angle of the screed 320 is adjusted in the front-back direction through the second driving cylinder 332.

[0038] In order to make the inclination adjustment of the screed plate 320 more stable, in some embodiments, second driving cylinders 322 are provided on both sides of the connecting rod 331. Specifically, two second driving cylinders 332 are provided at both ends of the screed plate 320, and the two second driving cylinders 332 are symmetrically distributed on both sides of the connecting rod 331. In this way, the inclination of the screed plate 320 is adjusted by a total of four second driving cylinders 332, and the adjustment process is more stable.

[0039] In some embodiments, the mounting seat 310 and the lifting platform 210 are hinged at a second hinge point. Specifically, the mounting seat 310 and the lifting platform 210 are hinged through a hinge shaft.

[0040] In this way, the entire leveling device 300 can rotate relative to the lifting platform 210 at the second hinge point. When the present application is not working, the leveling device 300 is rotated upward to be retracted. When work is required, the leveling device 300 is rotated to the horizontal position to start working. This can save the occupied space of the device.

[0041] In some embodiments, a rotation driving mechanism 400 is installed between the mounting seat 310 and the lifting platform 210. The rotation driving mechanism 400 is used to drive the mounting seat 310 to rotate at the second hinge point, thereby realizing the automatic rotation of the mounting seat 310.

[0042] In some embodiments, the rotation driving mechanism 400 includes a third driving cylinder 410, a first connecting rod 420, and a second connecting rod 430. One end of the first connecting rod 420 is hinged to the mounting seat 310, one end of the second connecting rod 430 is hinged at the second hinge point, and the other ends of the first connecting rod 420 and the second connecting rod 430 are both hinged to the piston rod of the third driving cylinder 410.

[0043] Specifically, the third driving cylinder 410 is horizontally installed in the middle of the lifting platform 210. A hinge seat is installed in the middle of the mounting seat 310. One end of the first connecting rod 420 is hinged to the hinge seat on the mounting seat 310. One end of the second connecting rod 430 is hinged to the middle of the hinge shaft between the mounting seat 310 and the lifting platform 210. The other ends of the first connecting rod 420 and the second connecting rod 430 are both hinged to the end of the piston rod of the second driving cylinder 332. During the working process, the second driving cylinder 332 drives the piston rod to horizontally extend and retract, and the piston rod drives the mounting seat 310 to rotate relative to the lifting platform 210 through the first connecting rod 420 and the second connecting rod 430.

[0044] In addition, the height of the screed plate 320 can also be adjusted by the rotation drive mechanism 400. When it is necessary to lower the height of the screed plate 320, after adjusting the mounting seat 310 to rotate downward by a certain angle through the rotation drive mechanism 400, the screed plate 320 can be adjusted to be horizontal through the inclination angle adjustment mechanism 330, and vice versa.

[0045] For the inclination angle adjustment of the screed plate 320, the coarse adjustment of the inclination angle of the screed plate 320 can be realized by rotating the mounting seat 310, and the inclination angle adjustment mechanism 330 is used for the fine adjustment of the inclination angle of the screed plate 320.

[0046] In some embodiments, the lifting drive mechanism 220 is a scissor lift mechanism.

[0047] The top of the scissor lift mechanism has a movable support leg and a fixed support leg. The fixed support leg is hinged and fixed to the fixing plate 110 extending backward from the top of the mobile vehicle 100. The movable support leg is slidably connected to the fixing plate 110. The lower end of the scissor lift mechanism is hinged to the middle of the lifting platform 210. A drive oil cylinder 221 is provided on the scissor lift mechanism. The drive oil cylinder 221 is used to drive the entire scissor mechanism to lift and lower. During the lifting and lowering process of the scissor lift mechanism, the movable support leg at its top slides relative to the fixing plate 110. The overall structure of the scissor lift mechanism is stable, and it is more stable during the process of driving the lifting platform 210 to lift and lower.

[0048] In some embodiments, the concrete pavement paver leveling machine further includes a vibrating device 500. The vibrating device 500 is arranged in front of the paving device 200. The vibrating device 500 is installed on the lifting platform 210. The vibrating device 500 includes a drive motor 510, a connecting frame 530 and a plurality of vibrating rods 520. Each vibrating rod 520 is arranged below the lifting platform 210 and is spaced along the length direction of the paving drum 230. Each vibrating rod 520 is connected to the connecting frame 530 through an elastic connecting piece. A lifting guiding device is arranged between the connecting frame 530 and the lifting platform. The connecting frame 530 is connected to the power output end of the drive motor 510. The drive motor 510 is used to drive the connecting frame 530 to lift and lower.

[0049] Specifically, a cavity is formed in the middle of the lifting platform 210. The driving motor 510 is fixed inside the cavity. Each vibrating rod 520 is connected to the connecting frame 530 through an elastic connecting piece. A nut is provided in the middle of the connecting frame 530. A screw rod is installed at the power output end of the driving motor 510. The screw rod is in threaded cooperation with the nut on the connecting frame 530. The lifting guiding device includes guiding rods 540 and guiding holes. There are two guiding rods 540, which are vertically fixed on the lower surface of the lifting platform 210. Guiding holes are provided on both sides of the connecting frame 530. The two guiding rods 540 are respectively assembled in the two guiding holes. The driving motor 510 drives the connecting frame 530 to lift along the guiding rods 540 by driving the screw rod to rotate. The distribution length of the vibrating rods 520 is the same as the length of the paving drum 230. The vibrating rods 520 are connected to the power source on the mobile vehicle 100. After the vibrating rods 520 are powered on, they can vibrate and work. Before the paving drum 230 levels the concrete, the concrete is first vibrated by the vibrating device 500 to compact the concrete. The specific vibrating process is that after the driving motor 510 drives the vibrating rods 520 to insert into the concrete through the connecting frame 530, each vibrating rod 520 is powered on to vibrate and compact the concrete.

[0050] The elastic connecting piece is a spring, which mainly plays a role in shock absorption.

[0051] In some embodiments, a cockpit 120 is provided on the mobile vehicle 100. A control panel and a driving control lever are provided in the cockpit 120. The staff directly sits in the cockpit 120 to drive the mobile vehicle 100 to move.

[0052] In some embodiments, a control box 130 is provided on the mobile vehicle 100. The control box 130 is connected to the control panel in the cockpit 120. The control box 130 is connected to the first driving cylinder 242, the second driving cylinder 332, the third driving cylinder 410 and the driving motor 510. The driver in the cockpit 120 can control the operations of the first driving cylinder 242, the second driving cylinder 332, the third driving cylinder 410 and the driving motor 510 through the control panel.

[0053] In some embodiments, a level is installed at the bottom of the mobile vehicle 100. The level is connected to the control box 130. The level is used to monitor the level condition of the ground in real time, so as to transmit the ground undulation condition to the control box 130. The control box 130 controls the tilt adjustment mechanism 330 according to the data fed back by the level, so that the tilt adjustment mechanism 330 adjusts the screed 320 to an angle the same as the ground inclination.
