Description

Roller type spreading and leveling machine

Technical Field

The utility model relates to a roller type paving and leveling machine, and belongs to the technical field of road and bridge construction machinery.

Background

The dry and hard concrete refers to concrete with low cement or mortar content, more coarse aggregates, low water-cement ratio and 20-11 s of Ubber consistency. During construction, strong vibration is needed to be adopted for compaction, otherwise, more pores are easily generated to influence the quality of concrete. The workability of the mixture can be expressed by a Weibo consistency index, the segregation and bleeding phenomena are avoided, the hardening is fast, the strength is high, and the concrete is commonly used for concrete products and members with high prefabricated strength requirements.

At present, some pavement constructions use hard and dry concrete. The construction of the hard concrete pavement also needs to be paved and leveled. However, there are not well suited paving levelers for dry hard concrete; most of the traditional paving levelers use a leveling vibrating plate or a vibrating rod to vibrate, lift and level concrete. However, in use, it was found that the impact effect of using a vibrating plate or a vibrating rod for hard concrete is not good, and the quality of the road surface after construction is not good.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model relates to a roller type paving and leveling machine, which is used for paving and leveling concrete pavements, and is particularly suitable for paving dry and hard concrete pavements.

The roll shaft type paving and leveling machine comprises a frame 1, and a pulp lifting roller 2, a leveling roller 3 and a walking roller 4 which are sequentially hinged to the lower end face of the frame 1. The pulp lifting roller 2, the leveling roller 3 and the walking roller 4 are driven by a motor to rotate. The slurry lifting roller 2 spreads the concrete and simultaneously strikes the slurry lifting roller. The leveling roller 3 is used for leveling the concrete pavement after slurry extraction, and the leveling of the pavement is ensured. The walking roller 4 is arranged on the top surface of the template 6 and is used for driving the whole machine to walk.

As shown in the figure, the paving and leveling machine is forward in the machine traveling direction, the pulp lifting roller 2 is positioned at the forefront, the leveling roller 3 is positioned behind the pulp lifting roller 2, and the traveling roller 4 is positioned behind the leveling roller 3.

The slurry lifting roller 2 of the utility model performs beating vibration on the concrete pavement in the working process, and the slurry lifting roller 2 is generally directly arranged as an eccentric roller.

The utility model arranges a control box 5 on a frame 1, and controls the rotating speed of a pulp lifting roller 2, a leveling roller 3 and a walking roller 4 through the control box 5. In a specific implementation, the pulp lifting roller 2, the leveling roller 3 and the walking roller 4 are driven to rotate by motors respectively. Wherein, the pulp extracting roller 2 and the leveling roller 3 are driven by a high-speed motor to rotate; the pulp extracting roller 2 rotates at a high speed and is responsible for spreading and extracting pulp; the leveling cylinder 3 levels its rear pressing surface. The traveling roller 4 is driven to rotate by a low-speed motor, and drives the whole machine to slowly move along the longitudinal direction of the paved road surface.

The rack 1 of the utility model is of a truss structure and has the characteristic of stable structure.

In the utility model, the walking roller 4 plays a role in driving and supporting the whole machine to move. The traveling roller 4 travels on the top surface of the formwork 6, and the traveling roller 4 actually functions as a traveling wheel. The slurry lifting roller 2 is an eccentric roller which rotates under the drive of a motor, the slurry lifting roller 2 is in contact with a concrete surface, and the eccentric roller has an eccentric vibration effect, so that the slurry lifting effect is achieved. The machine works behind a material distributing machine, and the material distributing machine can ensure the primary smoothness of a concrete surface after material distribution. The working surface part of the pulp lifting roller 2 is in contact with the concrete surface. The lower end surface of the leveling roller 3 also works on the concrete plane, and the leveling roller 3 plays a role of accurate leveling. The leveling thickness is controlled according to the set height of the template, and the top surface of the template is the paving surface. The leveling roller 3 performs surface pressing leveling.

The paving and leveling machine mainly depends on the high-speed rotation of the roller shaft for paving, so that the concrete is more uniform, the compactness of the surface layer of the pavement is enhanced, the cement concrete is compacted by the high-speed rotating and striking of the slurry lifting roller of the front shaft instead of vibration, the striking effect is far better than vibration, and the segregation phenomenon cannot be generated.
