Both sets of extension assemblies 400 are arranged between the pre-leveling roll 200 and the finishing leveling roll 300, and both sets of extension assemblies 400 are slidably connected to the spreading frame 100 in directions approaching or departing from each other. The two sets of spreader assemblies 400 are arranged co-linearly and the line on which the two sets of spreader assemblies 400 are common is arranged parallel to the pre-leveling roll 200.

Referring to fig. 1, each set of extension assemblies 400 includes a sliding plate 410 and an extension roller 420, the extension roller 420 is rotatably connected to the sliding plate 410, and the extension roller 420 is arranged parallel to the pre-leveling roller 200. Referring to fig. 1 and 2, a chute 110 is formed in the paving frame 100, an opening direction of the chute 110 is parallel to a length direction of the pre-leveling roller 200, and a cross section of the chute 110 perpendicular to the opening direction thereof is T-shaped. Referring to fig. 2 and 3, the two sliding plates 410 are each fixedly connected with a sliding block 411 corresponding to the sliding slot 110, and when the sliding plates 410 slide relative to the paving frame 100, the sliding blocks 411 are matched with the sliding slots 110 and slide relative to each other, and the sliding direction of the sliding blocks is the opening direction of the sliding slots 110.

Referring to fig. 1, the paving frame 100 is provided with two sets of support assemblies 500, one set of support assemblies 500 is used for supporting one sliding plate 410, and the support assemblies 500 are arranged on the side of the sliding plate 410 away from the extension roller 420. Each set of support members 500 includes a plurality of support bars 510, each support bar 510 being arranged parallel to the extension roller 420. The plurality of support rods 510 in the two sets of support assemblies 500 are disposed in a one-to-one correspondence, and the two corresponding support rods 510 are coaxially sleeved. The end parts of the two sliding plates 410 far away from each other are vertically and fixedly connected with a connecting plate 412, and each supporting rod 510 is vertically and fixedly connected with the corresponding connecting plate 412. One end of each support rod 510, which is far away from the connecting plate 412, penetrates through the paving frame 100.

When the sliding plate 410 moves, the sliding plate 410 drives the connecting plate 412 to move, and the connecting plate 412 drives the supporting rods 510 to move, so that the two coaxially sleeved supporting rods 510 slide relatively, and meanwhile, the supporting rods 510 slide relatively with the paving frame 100. When extension roller 420 paves cement concrete, bracing piece 510 supports sliding plate 410, reduces sliding plate 410 and takes place because of lacking the condition that the holding power inclines towards keeping away from cement concrete direction, increases the effect of paving of levelling device to cement concrete.

Referring to fig. 1, a driving assembly 600 is further disposed on the paving frame 100, and the driving assembly 600 includes a driving pipe 610 and two driving rods 620. The driving pipe 610 and the two driving rods 620 are coaxially disposed, and one driving rod 620, the driving pipe 610 and the other driving rod 620 are sequentially disposed along the length direction of the extension roller 420. The circumferential side surface of one end, close to each other, of the two driving rods 620 is provided with reverse threads, and the other ends, close to each other, of the two driving rods 620 are all inserted into the driving pipe 610 in a threaded manner. One end of each driving rod 620, which is far away from the driving pipe 610, penetrates through the paving frame 100 and is vertically and fixedly connected with the corresponding connecting plate 412. When the driving pipe 610 is rotated, the driving pipe 610 and the two driving rods 620 rotate relatively, and then the two driving rods 620 move toward a direction approaching or separating from each other, so that the sliding plates 410 move toward a direction approaching or separating from each other, thereby realizing synchronous adjustment of the two sliding plates 410.

Referring to fig. 2 and 3, in order to increase the stability of the driving pipe 610 during rotation and further increase the paving effect of the leveling device on the cement concrete, both ends of the driving pipe 610 are coaxially and fixedly connected with a limiting ring 611.

When the driving tube 610 is rotated, the driving tube 610 drives the limiting ring 611 to rotate, and the limiting ring 611 and the engaging groove 121 rotate relatively. The cooperation of spacing ring 611 and draw-in groove 121 can reduce the ascending motion of driving tube 610 at self axial to stability when increasing driving tube 610 and rotating, and then increase the effect of paving of leveling device to cement concrete.

The implementation principle of the leveling device for the trackless intelligent paver of the embodiment of the application is as follows: when the leveling device is used, the leveling device is installed on the spreading machine, then the spreading machine is started, and the spreading machine drives the leveling device to spread cement concrete. When the roadbed has a wider width, the driving pipe 610 is rotated, the driving pipe 610 and the two driving rods 620 rotate relatively, and then the two driving rods 620 move towards the direction away from each other. The driving rod 620 moves and drives the connecting plate 412, and the connecting plate 412 drives the sliding plate 410 to move towards the outside of the spreading frame 100, so that the flattening device is widened. When the two driving rods 620 drive the connecting plate 412, the connecting plate 412 drives the supporting rods 510 to move, the two corresponding supporting rods 510 slide relatively, and the supporting rods 510 slide relatively with the spreading frame 100. When the extension roller 420 rolls relative to the cement concrete, the support rod 510 supports the sliding plate 410, thereby increasing the stability of the extension roller 420 in paving the cement concrete.
