Example Embodiment

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

Example Embodiment

[0053] In the second embodiment, on the basis of the first embodiment, the ring gear 34 is rotatably connected with a stopper 39 which is in contact with the ratchet gear 33, and one side of the stopper 39 is fixedly connected with the inner wall of the ring gear 34 There is a spring 40. The other side of the stop 39 is provided with a baffle 41 fixedly connected to the ring gear 34. When the ring gear 34 rotates clockwise, the ratchet 33 does not rotate, and the spring 40 is compressed at this time. When the ring gear 34 rotates counterclockwise, the stopper 39 clamps the ratchet gear 33 and drives the ratchet gear 33 to rotate together. When the ratchet gear 33 rotates, it drives the driving helical gear 32 coaxially fixedly connected to it to rotate, thereby changing the first rack 19's meshing state.

Example Embodiment

[0054] In the third embodiment, on the basis of the first embodiment, a second helical gear 20 is co-engaged above the two first helical gears 16, and a roller 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 which is in contact with the inner bottom surface of the equipment base 1, and both sides of the roller rod 24 are provided with a fourth chute 43, Each of the fourth sliding grooves 43 is slidably connected with a rotating roller assembly 3. When the two switching rack sets 18 move up and down, they will drive the two left and right first rotating gears 17 to rotate in opposite directions at the same time, thereby driving the two The first helical gears 16 rotate in opposite directions. Because the second helical gear 20 meshes with the two first helical gears 16 at the same time, the second helical gear 20 will rotate at this time, and the rotation of the second helical gear 20 w...

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...
