Description
Technical field
The utility model belongs to the road building machinery field, relates in particular to the frame of a kind of material paver and paver.
Background technology
In recent years, Chinese highway construction project is increasing, is main with grade highway constructions such as Class I highway, speedways mainly, and these highway widths are big, and construction engineering units is high to quality requirement, requires the shaping that once paves of full width or half range.At present domesticly can't produce large-scale spreading machine voluntarily basically; Unit in charge of construction can only adopt two pavers to pave together, paves but adopt two pavers to unite, and there is seam in the road that paves; Road quality is difficult to control; And use two pavers not only purchase cost be double, the loss that when wear and tear in machines, causes also is double, makes the engineering cost of unit in charge of construction effectively to reduce.Domestic thus unit in charge of construction is strong to the increasing demand of the large-scale paver of broad way face.
The patent No. is that 00260856.1 Chinese utility model patent discloses a kind of basic unit stabilized soil paver; Comprise that the mounting bracket through belt sensor is installed in the mainframe on the crawler attachment; Be positioned at feed position that the band pushing tow before the mainframe rolls, be located at the anterior transversely movable cloth plough of mainframe, be positioned at the elementary module that paves behind the cloth plough, be rigidly connected in pave module and be positioned at the secondary sub-material spiral before the module that paves of secondary on the mainframe, this paver realizes that through the two-stage module that paves full width paves.But there is the deficiency of transition trouble in large-scale two Track Type pavers.
In order to solve the transition problem; Large-scale paver adopts the structure of four crawler belts supporting mainframe capable of free rotation usually; Like the patent No. is US6; The disclosed a kind of zero clearance of the United States Patent (USP) of 582,152 B2 variable-width concrete spreader, but comprise frame, the support frame of transversal stretching four installation columns, be loaded on crawler attachment on the frame through column is installed, be installed on feeding belt machine on the frame, by the spreader that is hinged on the draft arm traction on the frame; Spreader is through after stretching out in bracing frame after the frame and being installed in frame, and extends from the frame rear portion.When paving, material is delivered in the spreader hopper through the feeding belt machine, and is after the sub-material spiral sub-material before being located at hopper, floating by spreading plate.The spreader of this concrete spreader is positioned at the crawler attachment rear, and width can pave with the realization zero clearance greater than the width of both sides crawler belt.
The patent No. is US5, and 590,977 United States Patent (USP) also discloses a kind of four crawler belt pavers; Comprise mainframe, supporting mainframe four crawler belts, be installed in the anterior sub-material plough of mainframe and be installed in the member that paves of below, mainframe middle part; The curb girder of mainframe can be when paver paves direct of travel flexible, the back crawler belt of paver is installed in the end of telescopic curb girder, when paving; The curb girder elongation, back crawler belt is away from mainframe; When the transition transportation, in order to satisfy the dimensional requirement of highway transportation, curb girder is withdrawn, and four crawler belts just in time are positioned at four angles of mainframe, reduce the complete machine size.
Though more than several kinds of pavers can both realize paving than wide cut or zero clearance; But limited by frame dimensions; If lateral dimension is long, installs under the situation of more fixture component and unstable phenomenon can occur, and be installed in the frame tail end when the parts that pave; Because the mass transport distance is oversize, also is easy to generate segregation.
