Description
Technical field
The present invention relates to a kind of road building machinery, relate in particular to a kind of wide cut material paver of the basic unit's Stabilized Soil that is used to pave.
Background technology
As everyone knows, in road, railway, place construction and improvement project, paving of base material is a very important job.Base material typically refers to the mixture of building stones, sand, soil, flyash, industrial residue, lime, cement etc. and above-mentioned material, promptly usually said stabilizing material.The laying of base material at present adopts machineries such as bulldozer, loader and land leveller to pave usually.Adopt above-mentioned machinery to pave and have the deficiency of two aspects, the one, operating efficiency is low, and the 2nd, material easily produces segregation.The segregation of material is meant that particle diameter is bigger in the material that is paved building stones can be separated and floats over the top layer or flow to the edge from compound, thereby destroys the grating of material, weakened the supporting capacity of basic unit.
In recent years, China's highway construction project is increasing, mainly based on the standard highway construction, as Class I highway, speedway etc., these highway widths are big, and construction engineering units is to the quality requirement height, the shaping that once paves of stabilized zone requirement full width or half range paves, owing to lack large-scale Stabilized Soil paver special tool, unit in charge of construction or adopt large-scale asphalt paver to pave perhaps adopts the logical paver of two Daeporis to pave together.When adopting asphalt paver, require the asphalt paver specification many more than 13 meters, this mechanical price is comparatively expensive, and when paving more than 7 meters width, because machine power deficiency, the both sides segregation is very serious, and the planeness that both sides pave also can be significantly wavy because of housing rigidity Xiao Yi generation, reduced the credit rating of road; Simultaneously, the complex structure of asphalt paver involves great expense, and can not reduce the cost of unit in charge of construction; If unit in charge of construction adopts two pavers to unite and paves, there is seam in the road that paves, and road quality is difficult to control, can't reach construction requirement.
The patent No. is US3,636,832 U.S. Patent Publication a kind of two pass paver of the flexible pavement that is used to pave, comprise two independently pavers that are arranged side by side, connect by Z-shaped link between two independent pavers, each independently paver all have thrust unit, feeding-distribution device, control device and strike-off stick, strike-off stick can be stiff member or two kinds of forms of discerptible assembly.But each is the equal separate operaton of paver independently, and when needs paved the wide cut road surface, two pavers coupled together common operation by Z-shaped link, finish paving of wide cut road surface.Pave though the paver of this structure can carry out wide cut, structure is very complicated, and cost also is that meaning is not fairly obvious on two paver costs.
The patent No. is that 00260856.1 Chinese invention patent discloses a kind of basic unit stabilized soil paver, be provided with the car of installing by twisted axis that connects material before the frame, frame is contained on the track frame by four lifting columns, lifting column is provided with the sensor stand that sensor has been installed, framework platform is provided with the transversely movable cloth plough of height and adjustable angle, is positioned at cloth plough rear and is provided with elementary spreader and is rigidly connected in the secondary spreader on the frame and is positioned at the preceding sub-material spiral of secondary spreader.The lifting of this paver by frame makes the two-stage module that paves together regulate elevation automatically by the construction wire absolute altitude, adjusted on request and paved by the two-stage module that paves, and realizes that full width paves.But equally also there is complex structure in the paver of this structure, and the defective that involves great expense is restricted applying of its.
The patent No. is that 99115805.9 Chinese invention patent discloses a kind of bulk material spreader, the frame front end is provided with support wheel, frame postmedian below is provided with the leading V-arrangement spreading plate in tip, the frame tail end is provided with and connects the linkage that promotes machinery, frame is linked to be a rear portion by linkage and promotion machinery and relies on promotion machinery to promote to walk, the anterior long inflexible frame that paves when work at least that relies on support wheel to support walking, the V-arrangement spreading plate flexibly connects by lever and the support wheel before the frame that extends forward, the lever front end is regulated height up and down by adjusting device, and paving layer thickness and planeness are regulated and controlled to the V-arrangement spreading plate by the adjusting device between itself and frame rear portion.Material piles up on the ground by central rack when paving, and is shunted, is paved by the V-arrangement spreading plate, forms even paving layer at V-arrangement spreading plate rear portion.Paver with V-arrangement spreading plate can also be connected side by side, be linked to be integral body by connector between V-arrangement spreading plate and the frame and carry out wide cut and pave.But this mode only is that two pavers are simply connected, and when paving owing to wide cut, the intensity of the simple V-arrangement spreading plate that connects is not sufficient to form horizontal unbending rigidity, has a strong impact on spreading quality.
Summary of the invention
