The specific embodiment
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Below in conjunction with Fig. 2 to Fig. 5, preferred embodiment of the present utility model is described in further detail.As shown in Figure 2, a kind of paver comprises: frame (not shown), screed 100, lift cylinder 6, levelling oil cylinder (not shown), governor motion 7, large arm.Large arm comprises rear large arm 1 and front large arm 2, and rear large arm 1 and front large arm 2 are fixing by bolt 20.Bearing pin 9 is fixed on screed 100 through the pin shaft hole 10 of rear large arm 1, makes rear large arm 1 and screed 100 form hinged, and hold-down bolt 8 is fixed on screed 100 through the mounting hole 11 of rear large arm 1.
Governor motion 7 also is the mechanical tilt adjuster, for regulating screed 100 mechanical tilts, it is comprised of two spherical plain bearing rod ends, one or two and cap, a connected body, one end spherical plain bearing rod end of governor motion 7 is contained on the adjuster installing hole 12 of rear large arm 1 by a bearing pin, and other end spherical plain bearing rod end is contained on screed 100 by a bearing pin.Governor motion 7 is for adjusting the mechanical tilt of screed 100.When adjusting the elevation angle, first unscrew and cap and rear large arm 1 on hold-down bolt 8, then rotate connected body, make rear large arm 1 swing around bearing pin 9, thereby change the elevation angle of screed 100, after having adjusted, more also cap, hold-down bolt 8 are tightened.
Be provided with lift cylinder installing hole and levelling oil cylinder installing hole (not shown) on front large arm 2, an end of lift cylinder 6 is connected with frame, and the other end of lift cylinder 6 is connected with the lift cylinder installing hole of front large arm 2; One end of levelling oil cylinder is connected (not shown) with frame, and the other end of levelling oil cylinder is connected (not shown) with levelling oil cylinder installing hole.Lift cylinder 6 and levelling oil cylinder couple together frame and screed 100 by large arm, and whole screed 100 forms a set of suspension arrangement.During work, screed 100 is installed on laying and is quick condition.By stretching of levelling oil cylinder, make large arm swing, can change the work elevation angle of screed 100, thereby reach the purpose of levelling.By stretching of lift cylinder 6, can be so that screed 100 oscilaltions reach the purpose of regulating paving thickness.
As shown in Figure 4 and Figure 5, rear large arm 1 for the large arm of the utility model, be provided with junction plate 13 on one end of rear large arm 1, be provided with the bolt hole 130 be connected with rear large arm 1 on junction plate 13, bolt hole 130 can be screwed hole or through hole, the other end of rear large arm 1 is provided with adjuster installing hole 12, is provided with pin shaft hole 10 and mounting hole 11 between adjuster installing hole 12 and junction plate 13, and mounting hole 11 is between adjuster installing hole 12 and pin shaft hole 10.The center line of pin shaft hole 10 departs from the symmetrical central plane A of junction plate 13 upper bolt holes 130.
As shown in Figure 3, after the anti-dress of rear large arm 1, the expanded reach of 6 pairs of screeds 100 of lift cylinder will change, thereby has increased screed 100 paving thickness scopes.Because the center line of pin shaft hole 10 departs from junction plate 13 central plane A, pin shaft hole 10 is hinged with screed 100.If rear large arm 1 instead fills, perhaps the rear large arm 1 on the right exchanges with the rear large arm 1 on the left side, make the increase of screed 100 maximum depth of spread, the increase height of screed 100 is determined by center line and the junction plate 13 central plane A deviation distances of pin shaft hole 10, if deviation distance is larger, screed 100 paving thickness excursions are just larger.This technical scheme is due to only to anti-dress of rear large arm 1, perhaps the rear large arm 1 on the right exchanges with the rear large arm 1 on the left side, and rear large arm 1 does not change, therefore can not cause the variation of rear large arm 1 angle, that is to say, do not need again to adjust by governor motion 7 mechanical tilt of screed.
After preventing the anti-dress of rear large arm 1, or, after rear large arm 1 exchange on the rear large arm 1 on the right and the left side, cause screed 100 mechanical tilts variations and screed 100 elevation angle adjustable ranges to change.As shown in Figure 4 and Figure 5, the utility model is positioned at the center line of adjuster installing hole 12 and pin shaft hole 10 and mounting hole 11 in same plane B, and plane B is vertical with junction plate 13 installed surfaces on rear large arm 1, after making the anti-dress of rear large arm 1, after perhaps right back large arm and left back large arm exchange, can not cause screed 100 mechanical tilts to change, that is to say, not need to readjust screed 100 mechanical tilts.Can not affect screed 100 elevation angle adjustable ranges simultaneously yet.This utility model has increased screed 100 expanded reaches of paver, and the function that makes to pave realizes large thickness paving operation, in regulating the expanded reach process, has saved adjusting time and manpower in addition, has improved adjusting efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
