Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement paving, and more specifically to a hot joint compacting device for asphalt pavement paving. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly in the form of liquid or semi-solid petroleum. The surface is black and soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt: among them, coal tar asphalt is a by-product of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, some of which form mineral layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in industries such as coatings, plastics, rubber, and paving roads.

[0003] For example, the announcement number CN117188253A discloses a hot joint compacting device for asphalt pavement paving, which mainly includes a transmission shaft and a base for installing a compacting roller, a bearing is provided at the connection between the base and the compacting roller, the central axis of the compacting roller passes through the bearing to realize the rotation of the compacting roller around the axis of the central axis, one end of the central axis of the compacting roller is fixedly connected to a driven gear, a fixed frame is provided on the top of the base, a counterweight is installed inside the fixed frame, a stepper motor is installed on the outer wall of the fixed frame, the stepper motor is electrically connected to the control device, the output shaft of the stepper motor is fixedly connected to an output gear, and the two ends of the transmission shaft are fixedly connected to transmission gears meshing with the output gear and the driven gear respectively. The hot joint compacting device for asphalt pavement paving improves the construction efficiency, construction quality and safety, as well as the portability during use and transportation through the internal structural innovation and the handle design of the outer wall of the box shell, and plays a significant role in the construction of hot joints of asphalt pavement.

[0004] It can be seen from the above-mentioned public scheme that the height of the hot joint compacting wheel for asphalt pavement paving is currently mostly fixed, and it is not easy to adjust it up and down according to the requirements of use. The compacting wheel that is difficult to adjust is easy to collide with the road surface when encountering uneven road surfaces, and is easy to damage the road surface that does not need to be compacted, which brings a lot of inconvenience to use. At the same time, when the compacting shaft rotates, there is surface contact friction between the rotating shaft and the sleeve. The surface contact friction not only generates a large friction force that affects the rotation of the compacting shaft, but also easily causes friction damage at the contact point, thereby wasting a lot of mechanical energy.
