Description
Technical field
The utility model belongs to the engineering road building machinery, relates in particular to a kind of zero clearance wide cut road machine that road pavement paves that can be used for.
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 this paver adopts two crawler belt frames, and paver can't be cut to voluntarily when the needs short distance is cut to, must be by the loading vehicles transportation of cutting to; Make troubles to unit in charge of construction, and increase cost virtually.
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.But,, cause spreader distant apart from frame because spreader is installed in the rear of the crawler attachment of installing through the hinge pivoted arm; Before material is delivered to spreader from the paver front portion; Feeding belt machine distance is longer, and the feeding belt of the long distance sideslip that skids easily causes defeated material amount unstable; Fault rate is high, and material is easy to generate segregation.
Though more than two kinds of pavers can realize that wide cut paves, the shortcoming that all have complex structure, involves great expense.

The spreading plate of the utility model is an elementary spreading plate of being located at the mainframe lower front.
The spreading plate of the utility model is a secondary spreading plate of being located at the mainframe lower rear.
Walk forward track of the utility model and walk backward track are that electricity drives traveling crawler.
Swing arm before being equipped with, the both sides of the mainframe front end of the utility model is installed; Be provided with the preceding installation column that walk forward track is installed in the bottom at preceding installation swing arm front end; In the both sides of mainframe rear end the back is installed swing arm is installed, in the back swing arm rear end is installed and is provided with the back installation column that walk backward track is installed in the bottom.
The feeding-distribution device of the utility model is the sub-material spiral, and this sub-material spiral side stretches out in outside the mainframe.
The feeding-distribution device of the utility model is the sub-material plough.
The front portion of the side shield of the utility model is positioned at the walk forward track inboard.
Can know that by technique scheme the elementary spreading plate two ends of the utility model stretch out in the traveling crawler outside, when limit material sub-material first, can realize that the zero clearance paves, can accomplish Stabilized Soil etc. and spread the construction that paves of the zero clearance of shape basic unit material.And in the further scheme of the utility model, the secondary spreading plate also is the zero clearance spreading plate, the construction that paves of the zero clearance that can accomplish other mixed material.
