Abstract
The utility model relates to a lifter of a snow removing shovel, which comprises a fixed support connected with a girder at the front end of an automobile chassis, a lifting oil cylinder, a lifting rack, a pull rod and a triangular bracket, wherein an upper supporting ear of the fixed support is connected with the middle part of the fixed support, both ends of the fixed support are connected with a lower supporting ear of the fixed support, a supporting ear at the rear end of the lifting rack is hinged with the lower supporting ear of the fixed support, and a supporting ear at the front end of the lifting rack is hinged with a central hole of the triangular bracket; one end of the pull rod is hinged with the upper supporting ear of the fixed support, and the other end of the pull rod is hinged with an upper supporting ear of the triangular bracket; a supporting ear at the tail of a cylinder of the lifting oil cylinder is hinged with a middle supporting ear of the lifting rack, and a supporting ear of a piston rod of the lifting oil cylinder is hinged with a lower supporting ear of the triangular bracket. The utility model has the advantages of simple and compact structure, small size and light weight; moreover, the lifting oil cylinder works in a positive cavity, and the travel range is short, which ensures the safe lift of a snow removing shovel.
Description
Affiliated technical field
The utility model relates to a kind of snow removing shovel lifting device that is installed in multiple vehicle front end.
Background technology
Lifting device is one of chief component of snow removing shovel, and its function is that the snow removing shovel lifting is broken away from ground, prevents that the hard bossing of snow removing shovel head and ground interferes when vehicle ', causes the unnecessary damage of equipment; The contraction that present existing lifting device is a parallel-crank mechanism by an oil cylinder is with snow removing shovel lifting built on stilts, and not only bulky on the whole, weight increases, and oil cylinder is the work of anti-chamber, and system pressure is higher during lifting.
The utility model content
Technology of the present utility model is dealt with problems and is: overcome the deficiencies in the prior art, provide a kind of simple in structure, volume is little, and is in light weight, can realize the device of snow removing shovel lifting.The snow removing shovel lifting device
Technical solution of the present utility model is: a kind of snow removing shovel lifting device, comprise: the fixed bearing, elevating ram, the lifting frame that are connected with automobile chassis front end crossbeam, it is characterized in that: also comprise pull bar, triangle support plate, the centre of fixed bearing is connected to the fixed bearing upper journal, the two ends of fixed bearing are connected to the fixed bearing down journal, lifting frame rear end journal stirrup is connected with fixed bearing down journal hinge, and lifting frame front end journal stirrup is connected with the interstitial hole hinge of triangle support plate; Pull bar one end is connected with fixed bearing upper journal hinge, and the other end is connected with the upper journal hinge of triangle support plate; The cylinder barrel afterbody journal stirrup of elevating ram is connected with journal stirrup hinge in the middle of the lifting frame, and the piston rod journal stirrup of elevating ram is connected with the down journal hinge of triangle support plate.
Operating principle of the present utility model is: when the piston rod of elevating ram begins to extend, the down journal that promotes the triangle support plate earlier rotates around the intermediate support that is connected with the lifting frame front journal, because the upper journal and the pull bar of triangle support plate are hinged, and the other end of pull bar and fixed bearing upper journal are hinged, so the intermediate support of triangle support plate rotates around the fulcrum that is connected with pull bar, journal stirrup rotates around the fixed bearing down journal after driving lifting frame simultaneously, and snow removing shovel is lifted to the position of requirement the most at last; Otherwise piston rod shrinks and then falls to ground.
The beneficial effect that the utility model compared with prior art has is: simple and compact for structure, volume is little, and is in light weight, elevating ram positive chamber work, and stroke is short, has guaranteed the safe lifting of snow removing shovel.

Fig. 3 is the structure vertical view of Fig. 1;
Fig. 4 is the lifting frame structure vertical view in the utility model.
The specific embodiment
As Fig. 1,2,3, shown in 4, present embodiment is by the fixed bearing 1 that is connected with automobile chassis front end crossbeam, elevating ram 5, lifting frame 2, pull bar 3, triangle support plate 4, fixed bearing upper journal 6, fixed bearing down journal 7 is formed, fixed bearing 1 is connected and fixed with the inspection of automobile chassis crossbeam spiral shell and is one, lifting frame 2 rear end journal stirrups 21 and fixed bearing down journal 7 are connected by pin hinge, journal stirrup 22 is connected by pin hinge in the middle of the afterbody journal stirrup of elevating ram 5 cylinder barrels and the lifting frame 2, the piston rod journal stirrup of elevating ram 5 and the down journal of triangle support plate 4 41 are connected by pin hinge, the middle journal stirrup of triangle support plate 4 is connected by pin hinge with the front journal 23 of lifting frame 2 and an end of pull bar 3 respectively with upper journal, and the other end of pull bar 3 and fixed bearing upper journal 6 are connected by pin hinge.When elevating ram 5 stretches out, drive triangle support plate 4 and rotate around middle journal stirrup, drive lifting frame 2 simultaneously and rotate around fixed bearing down journal 7, make snow removing shovel lifting built on stilts meet the requirements of distance; When elevating ram 5 shrank, lifting frame 2 counter-rotation fell to ground.
As shown in Figure 4, lifting frame 2 is " A " glyph framework structure, uses section bars such as channel-section steel or rectangular steel pipe to be welded, pull bar 3 is " one " type structure, is welded by section bar and steel plate, and two ends are provided with hinged point, triangle support plate 4 is " L " type mechanism, at two ends and corner have three hinged points.
