DETAILED DESCRIPTION

[0022] Example one

[0023] As Figures 1-3 shown, the asphalt pavement construction paving structure proposed in the embodiment comprises a tractor head 1, a mounting plate 9, two groups of road roller mechanisms and four groups of lifting driving mechanisms.

[0024] The tractor head 1 is provided with a trailer plate 2, and the tractor head 1 is arranged to tow the equipment to move forward, and the trailer plate 2 is also provided with wheels.

[0025] The two groups of road roller mechanisms are arranged below the trailer plate 2, and the road roller mechanism comprises a compression roller 3 and a mounting frame 10, and the compression roller 3 is rotatably installed on the mounting frame 10; the mounting plate 9 is movably connected with the trailer plate 2 in the vertical direction, and it is necessary to supplement that a limiting plate 8 is arranged above the trailer plate 2, a plurality of movable columns 23 are connected between the limiting plate 8 and the mounting plate 9, the movable columns 23 movably penetrate the trailer plate 2, through the arrangement of the above structure, the mounting plate 9 is limited to move horizontally, so that the mounting plate 9 can only move vertically, the two mounting frames 10 are slidably installed on the mounting plate 9, and the mounting plate 9 is provided with a power assembly for driving the two mounting frames 10 to move in opposite directions, the power assembly comprises a servo motor 11 and a two-way screw 12, the servo motor 11 is arranged on the mounting plate 9, the two-way screw 12 is installed at the end of the servo motor 11, and the two mounting frames 10 are connected with the connecting sliders 13, and the two connecting sliders 13 are symmetrically arranged on the two-way screw 12 and are in threaded connection with the two-way screw 12.

[0026] The two mounting frames 10 are connected with the fixed frames 14, the bottom ends of the two fixed frames 14 are connected with the scrapers 15, and the scrapers 15 are used to scrape the residual asphalt on the surface of the compression roller 3.

[0027] The four groups of lifting driving mechanisms are respectively installed at the two ends of the two mounting frames 10, and the lifting driving mechanism comprises a hydraulic cylinder 5, a roller mounting seat 6 and a first roller 7, the hydraulic cylinder 5 is installed at the end of the corresponding mounting frame 10, the roller mounting seat 6 is installed on the output shaft of the hydraulic cylinder 5, and the first roller 7 is installed on the roller mounting seat 6.

[0028] Specifically, under the cooperation of the two groups of road rolling mechanisms and the power assembly, the road rolling range of the equipment can be adjusted, and the applicability is improved. The specific operation is as follows:

[0029] The power assembly drives the two connecting sliding blocks 13 to move closer to or away from each other, and then drives the two mounting frames 10 to move in opposite directions. When the two connecting sliding blocks 13 move closer to each other, the two mounting frames 10 move to the two sides of the trailer plate 2, respectively. The mounting frame 10 drives the movement of the compression roller 3, thereby improving the road rolling range of the equipment. The equipment should be ensured to travel in the center during operation. The length of the compression roller 3 is L, and the optional range d of the road rolling is L≤d<2L. It should be noted that when adjusting the road rolling range of the equipment, the multiple hydraulic cylinders 5 should be started simultaneously. The hydraulic cylinder 5 drives the roller mounting seat 6 to move downward until the first roller 7 contacts the ground and lifts the compression roller 3. In this way, the friction between the compression roller 3 and the ground during movement can be avoided. In addition, the compression roller 3 also needs to be lifted when not working to avoid damage to the surface of the compression roller 3 during movement of the equipment.

When the second roller 20 moves to the pit position of the road surface, the second roller 20 sinks into the pit and drives the L-shaped rod 19 to move downward. The horizontal rod part at the top end of the L-shaped rod 19 moves downward. At this time, the detection data of the distance measuring sensor 21 at the bottom end changes and feeds back the signal to the controller. The controller can be a PLC controller. After receiving the feedback signal, the controller controls the horn on the vehicle to sound an alarm, thereby playing a warning role. When the second roller 20 moves to the protruding part of the road surface, the L-shaped rod 19 moves upward, the horizontal rod part at the top end of the L-shaped rod 19 moves upward, and the detection data of the distance measuring sensor 21 installed at the top end changes and feeds back the signal to the controller. The controller plays an alarm function.
