Abstract
The utility model discloses a mechanical widen type screed hydraulic widening device of spreader machine, which comprises a guide rail fixing component arranged at two ends of the mechanical widen type screed of spreader machine. A movable width reduction plate component is arranged in the guide rail fixing component. A cylinder head end of a hydraulic telescopic cylinder is fixedly connected with the guide rail fixing component, and the piston rod end is fixedly connected with the width reduction plate. The utility model has simple structure, easy operation and reliable performance. The device makes the deficiencies of the mechanical widen type screed can not stepless change the spreading width, and can achieve the stepless change of the spreading width, which makes the spreading machine not only has the rigidity of the large width spreading operation but also has the conveniences of telescopic screed, improves the working efficiency of the spreading machine. Meanwhile the utility mode guarantees the operational quality of the large spreading width and effectively solves the difficulty of the spreading operation in the tunnel of the high-grade highway.
Description
Technical field
The utility model belongs to the road building machinery technical field, is specifically related to the flared crossing screed hydraulic pressure Width adjusting device of a kind of paver machinery.
Background technology
The multi-functional paver that can realize that big width, big thickness, highly dense solidity pave is adopted in the construction of high-grade arterial highway more, as: the super 2500 type pavers of ABG525, Fu Gele, it is flared crossing that their screed is machinery, why adopt mechanical flared crossing screed, good rigidly during based on its width operation more than 12m, the surface evenness of build is good, compactness is high and compactness is even.Yet mechanical flared crossing screed is difficult for realizing wide variety, generally is to have a machinery of regulating by leading screw to subtract wide device in the screed two ends, and rotational lead screw subtracts wide plate side shifting inwards, realizes the not too big wide variation that subtracts.In the practical operation, rotational lead screw is difficulty not only, and thisly subtracts the wide combined width that does not change screed, and it is only applicable to hide such as well lid etc. does not need to cover the occasion of material of paving.The construction machinery that resembles bridges and culverts, ramp location subtracts wide device and just seems powerless, and the bridge pier that width is narrower and lay the road both sides on road surface, bridges and culverts place makes the screed of broad to pass through.Therefore can not realize continuous paving operation, have a strong impact on spreading quality, the road bridges and culverts of constructing when running into especially for a long time, it is bad more that situation becomes.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of paver simple in structure, easy to operate, dependable performance mechanical flared crossing screed hydraulic pressure Width adjusting device.To realize the stepless variation of paving width, make paver not only have the rigidity of big width paving operation but also convenience with telescopic ironing table freely, and improve the operating efficiency of paver, guarantee the operation quality of big paving width simultaneously.
For achieving the above object, the technical scheme that the utility model adopted is: the flared crossing screed hydraulic pressure Width adjusting device of a kind of paver machinery, it is characterized in that: it comprises the fixed guide assembly 1 that is installed on flared crossing screed 4 two ends of paver machinery, the activity that is equipped with in fixed guide assembly 1 subtracts wide plate assembly 2, the cylinder head end of hydraulically extensible oil cylinder 3 is fixedlyed connected with fixed guide assembly 1, and its piston rod 6 ends subtract wide plate assembly 2 with activity and fixedly connected.
The utility model compared with prior art has the following advantages: the utility model is simple in structure, easy to operate, dependable performance, this device has remedied the defective that mechanical flared crossing screed can not stepless variation paving width, the more convenient paving operation that broadens frequently, can realize the stepless variation of paving width, the convenience that makes paver not only have the rigidity of big width paving operation but also have a telescopic ironing table freely, improved the operating efficiency of paver, guarantee the operation quality of big paving width simultaneously, solved the difficult problem of high-grade highway bridges and culverts place paving operation effectively.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of the utility model and mechanical flared crossing screed.
Fig. 2 is the structural representation of the utility model Breadth Maximum position.
Fig. 3 is the structural representation of the utility model minimum widith position.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, the utility model comprises the fixed guide assembly 1 that is installed on flared crossing screed 4 two ends of paver machinery, the activity that is equipped with in fixed guide assembly 1 subtracts wide plate assembly 2, the cylinder head end of hydraulically extensible oil cylinder 3 is fixedlyed connected with fixed guide assembly 1 usefulness steady pin 5, and its piston rod 6 ends subtract wide plate assembly 2 usefulness connecting pins 7 with activity and fixedly connected.
As shown in Figure 2, when hydraulically extensible oil cylinder 3 contracted to the shortest position, activity subtracted wide plate assembly 2 and is positioned at maximum position, just the construction width of road; As shown in Figure 3, activity subtracts wide plate assembly 2 and is positioned at minimum position when hydraulically extensible oil cylinder 3 extends the longest position, and it is consistent with the combined width of mechanical flared crossing screed 4, just the width of roadway at bridges and culverts place.3 actions of hydraulically extensible oil cylinder can be by handling button realization on the paver console.
