Description

Multifunctional transfer machine

Technical Field

The utility model belongs to the field of material transferring engineering equipment and construction technical methods required by road and airport construction, maintenance and repair and other pavement operations. In particular to a synchronous stone-breaking seal machine, a pavement paving transfer machine and an asphalt mixture transfer vehicle.

Technical Field

The asphalt mixture transfer is mainly used for continuously feeding the road paver in the pavement construction of the asphalt pavement, and reduces the temperature segregation and aggregate segregation of the asphalt mixture in the transportation process. The coordination service object and the function are relatively single. For example: at present, synchronous chip seal, micro-surfacing and slurry seal construction in China generally adopts an operation mode that a synchronous chip seal vehicle and slurry seal vehicle, namely vehicle-mounted equipment, carry out intermittent process. Firstly, filling raw materials such as mineral aggregate, asphalt, water and the like in a stock ground, then, running to the site for construction operation, and when one raw material is used up, obtaining the stock ground for loading again, thus repeatedly constructing. For example: the synchronous chip seal coat vehicle has limited raw material quantity when being filled with one vehicle, and limited paving area limited by different widths, mineral aggregate density and asphalt spraying quantity, and equipment must return to a stock yard for adding raw materials in long-distance large engineering construction and then go to a construction site again for next construction operation; the micro-surfacing and slurry seal coat vehicle are the same. Therefore, most of the time of the equipment is wasted on transporting raw materials, the high equipment utilization rate is low, and the construction efficiency is not ideal. In large-scale engineering, a plurality of devices are commonly adopted to work sequentially in turn, so that paving joints are easy to frequently influence the quality of the whole pavement in the long-distance construction process. The reduction ratio of the truck chassis gearbox is selected and used, and the low-speed construction speed and the high-speed transportation running speed cannot be both plagued. In addition, joints and process stub bars are necessarily generated once per operation, and if the generated joints are poorly controlled, the overall construction quality is affected.

A large number of researches at home and abroad show that the failure of pavement interlayer treatment is one of the important reasons for causing pavement quality problems, if the interlayer bonding force is insufficient, load, especially heavy load and overload, caused by pavement driving are alternately added in four seasons through natural environment, interlayer extrusion and shearing deformation are continuously accumulated, so that the pavement is subjected to diseases such as premature falling, cracking, pitting, pushing, pavement roughness and the like. At present, the road surface is pretreated by adopting a non-special cleaning device and a portable shoulder-back blower before construction. Engineering practice reflects: the technical method has very limited road surface cleaning effects on deposited ash layers, asphalt oxide layers, unstable materials and the like of the original road surface, and obviously cannot meet the requirements of construction process design; and the roughening treatment can not be carried out on the unstructured textured pavement so as to increase the bonding area and strengthen the bonding force between pavement layers. Therefore, the traditional pavement pretreatment construction process is very labor-and time-consuming, low in construction efficiency, and occupies a large amount of equipment and manpower, so that the construction cost is increased, the method is uneconomical, and the method is not suitable for carbon peak reaching and carbon neutralization.

In view of the above problems, a new solution is provided-a multifunctional transfer machine and an application method.
