Embodiment 1

[0052] Embodiment 1, the present invention is a rolling device for low-temperature modified asphalt concrete construction, including an equipment base 1, characterized in that the equipment base 1 is hollow inside, and a hydraulic cylinder is fixedly connected to the lower end surface of the equipment base 1 12. A square casing 4 is sheathed on the outside of the hydraulic cylinder 12, and the square casing 4 is fixedly connected to the bottom surface of the hydraulic cylinder 12, and a third rack is fixedly connected to the side wall of the square casing 4 35, two first sliding grooves 13 are opened on the symmetrical side walls adjacent to the third rack 35 on the square sleeve 4, and the two first sliding grooves 13 on the same side wall A first slider 21 is slidably connected inside, and two symmetrically distributed second chute 23 is opened on the first slider 21, and a roller rotating device 14 is slidably connected in the second chute 23 , the roller rotating device 14...

Embodiment 2

[0053] Embodiment 2. On the basis of Embodiment 1, the ring gear 34 is rotatably connected with a stopper 39 that is in contact with the ratchet 33, and one side of the stopper 39 is fixedly connected to the inner wall of the ring gear 34. There is a spring 40, and the other side of the block 39 is provided with a baffle plate 41 fixedly connected to the ring gear 34. When the ring gear 34 rotates clockwise, the ratchet 33 does not rotate, and now the spring 40 is compressed. When the ring gear 34 rotates counterclockwise, the block 39 clamps the ratchet 33 and drives the ratchet 33 to rotate together. When the ratchet 33 rotates, it drives the active helical gear 32 coaxially and fixedly connected with it to rotate, thereby changing the first rack 19 meshing states.

Embodiment 3

[0054] Embodiment 3, on the basis of Embodiment 1, a second helical gear 20 is meshed above the two first helical gears 16, and a roller rotating rod 24 is coaxially fixedly connected above the second helical gear 20 , both ends of the roller rod 24 are fixedly connected with a runner 42, the runner 42 is in contact with the inner bottom surface of the equipment base 1, and a fourth chute 43 is arranged on both sides of the roller rod 24, Each sliding connection in the fourth chute 43 has a rotating roller combination 3. When the two switching rack groups 18 move up and down, they will drive the left and right first rotating gears 17 to rotate in opposite directions at the same time, thereby driving the two gears. The two first helical gears 16 rotate oppositely to each other, because the second helical gear 20 meshes with the two first helical gears 16 at the same time, so the second helical gear 20 will rotate at this time, and the rotation of the second helical gear 20 will ...

Abstract

The invention relates to a rolling device for low-temperature modified asphalt concrete construction and effectively solves problems that an existing rolling device is non-adjustable in rolling rangeand poor in adaptability, and asphalt concrete is extremely prone to adhering to rollers. The rolling device is characterized in that a roller rotating device is adopted, a rolling range is adjustable, switching between a single-row wheel mode and a double-row wheel mode is performed according to actual conditions, adaptability is strong, a rack switching device is adopted so that switching between the single-row wheel mode and the double-row wheel mode is more convenient and faster, a reciprocating water spraying device is adopted so that a rolling device can spray the water to the rolling wheels while walking, the rolling wheels are cooled, and asphalt concrete is prevented from adhering to the rolling wheels. The rolling device is easy to operate, high in adaptability and adjustable inrolling range, and construction efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the field of asphalt concrete construction, in particular to a rolling device for low-temperature modified asphalt concrete construction. Background technique [0002] With the progress of the times and the convenience of transportation, every household has a car. People have higher and higher requirements for the quality of roads, and road traffic has become the lifeblood of the country's economic development. Because asphalt concrete has many good properties performance, so it is widely used to pave roads all over the world. As we all know, asphalt concrete is a three-phase system composed of gas phase (air), liquid phase (asphalt) and solid phase (aggregate), and its compaction process is mainly by means of some The rolling equipment loads the paved asphalt concrete in some form, overcomes the internal friction and cohesion of the asphalt concrete, makes the large and small aggregates move closer to each other, and reduces t...
