Abstract
The utility model discloses a device preventing road surface paving vertical eduction, comprising an adjustment panel (5) arranged beneath a spiral striker plate of paving machine (1) and whose height is adjustable up and down, and an elastic rubber plate (6) arranged below the adjustment panel by a pressure bar (4) through bolts (7). The utility model has the advantages of simple structure, safe and reliable operation, and convenient to assembly and disassembly. Because the adjustment panel is arranged beneath the spiral striker plate of paving machine and the elastic rubber plate is connected with an adjustment panel, the utility model makes the distance between striker plate and ground adjustable, thereby efficiently preventing vertical eduction when making pavement with great depth and ensuring the quality of paving.
Description
Technical field
The utility model belongs to the road building machinery technical field, is specifically related to a kind of device that prevents the vertical segregation of pavement spread in big width, big thickness paving operation.
Background technology
Pavement quality is the general designation of durability, safety and the comfortableness of road surface use.In the last few years, although study and put into practice from many-sides such as highway design, construction technology, operation managements, yet the early stage damage phenomenon on road surface was still very serious, mainly showed as: the subgrade strength deficiency, cause structural destruction, as cracking, sinking; The road surface damage by water is bad, causes hole groove, loosely organized, segregation; Rut, cracking, bellding under the overweight car effect; And the local lesion of special road section etc., and road surface repair difficulty is big, the high The coast is clear that influences of cost.
Damage in the phenomenon on above-mentioned road surface, because the damage that the material segregation causes when paving, it is bad mainly to show as subgrade strength deficiency and road surface damage by water.When the material segregation betides roadbed material, because the local material grating changes, roll unreal in addition, the void content height, the whole physical and mechanical property of base layer structure is reduced and inhomogeneous, the uneven and local modification of modification increases under the heavy load effect, and the road surface will form crackle and destruction because of this modification reflection, simultaneously, bad and local the sinking of the damage by water of roadbed easily takes place in big void content.Asphalt pavement material segregation divides gather materials segregation and demixing temperature, and gathering materials segregation causes local grating to change, the many and middle small pellets of Coarse Aggregate after a little while, roll unreal, in conjunction with not tight, the void content height, when heavy load impacted, big pellet dislocation formed the road surface and cheats groove; In addition, porosity is big, and flowing pressure punctures surface layer, can directly cause bleeding, and basic unit's end face is come to nothing; The middle much pellets of small pellets can form rut in default of the support strength of big aggregate after a little while easily, and this has become a difficult problem in the asphalt pavement construction.Given this, " highway road surface construction technique normalizing " and " asphalt highway construction technique normalizing " all the construction technology to paver proposed suggestion, mainly control from paving width and thickness aspect, attempt to prevent wide cut, the big thickness generation mixture segregation that paves, and suggestion uses two-shipper and machine operation layering to pave.Practice shows that this technology suggestion also fails fundamentally to solve the segregation problem, and has produced other problem, as integral smoothness reduction, productivity ratio reduction, parallel operation seam crossing segregation and vertical segregation etc.
Material is how to be transferred, how to produce segregation again? the power transmission shaft that has helical blade rotates in the hopper that is surrounded by spiral striker plate and screed, termination with the mass transport screed in the hopper, the material that is transferred in hopper is because the effect of gravity, blade rubbing power and hopper frictional force, do not rotate together with spiral, but migrate to throughput direction along hopper, and blanking below spiral ceaselessly, simultaneously to screed forward position plug material.Spiral striker plate lower edge is liftoff should a gap, passes through performance demands to adapt to.From considering general this road clearance by performance more than 180mm, this is considered to suitable gap, for the defeated material of spiral, seems excessive, and existing paver mostly is to be nonadjustable by such parameter designing and road clearance.Spiral is when defeated material, and material is extruded from this excessive gap, and big pellet very easily tumbles, the shop is dispersed in the basic unit, forms the big pellet of one deck, and Here it is vertically emanates, be a kind of in several segregations, refer at the many and few segregation phenomenon up and down of the big pellet in top of the big pellet in top and the bottom, cross section that paves.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, safe and reliable, the device that prevents the vertical segregation of pavement spread of easy installation and removal.This device makes the ground clearance of paver spiral striker plate adjustable, has effectively prevented vertical segregation when big thickness paving operation, has guaranteed spreading quality.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of device that prevents the vertical segregation of pavement spread, it is characterized in that: it comprises and is installed in paver spiral striker plate 1 below and its height adjustable adjustable plate 5 up and down that press strip 4 is fixedly mounted on adjustable plate 5 bottoms by bolt 7 with elastic rubber slab 6.
The utility model compared with prior art has the following advantages: the utility model is simple in structure, safe and reliable, easy installation and removal, because adjustable plate and the elastic rubber slab of fixedlying connected with adjustable plate are installed below paver spiral striker plate, make the ground clearance of paver spiral striker plate adjustable, when big thickness paving operation, effectively prevent vertical segregation, guaranteed spreading quality.

Fig. 1 is installed in structural representation on the paver spiral striker plate 1 for the utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the front view of the utility model press strip 4.
Fig. 4 is the front view of the utility model adjustable plate 5.
Fig. 5 is the front view of the utility model elastic rubber slab 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As depicted in figs. 1 and 2, the utility model comprises by bolt 8 and is installed in paver spiral striker plate 1 below and its height adjustable adjustable plate 5 up and down, according to different suitably 1 road clearances of adjustable screw striker plate of paving thickness with material, press strip 4 is fixedly mounted on adjustable plate 5 bottoms by bolt 7 with elastic rubber slab 6,1 road clearance of spiral striker plate can be adjusted to minimum, and the outer Zhang Xiaoguo that utilizes elastic rubber slab 6 reduces the defeated material resistance of defeated material spiral 2, prevent that simultaneously big pellet from tumbling, guaranteed the spreading quality of screed 3.
As Fig. 3, Fig. 4 and shown in Figure 5, described adjustable plate 5 tops have the bar shaped bolt hole 5-1 that is used to regulate 6 road clearances of elastic rubber slab, bolt 8 can be fixedly mounted on adjustable plate 5 paver spiral striker plate 1 below by bar shaped bolt hole 5-1, adjustable plate 5 bottoms have and are used for the circular bolt holes 5-2 of fixedlying connected with elastic rubber slab 6 with press strip 4, have on described press strip 4 and the elastic rubber slab 6 and adjustable plate 5 circular bolt holes 5-2 corresponding press strip bolt hole 4-1 and rubber tile bolt hole 6-1.
