Abstract
The invention relates to a road leveling machine. The road leveling machine comprises driving wheels, a driving cab, a machine frame and a grinding wheel, wherein a hydraulic device is arranged on each of two sides of the machine frame; a pressurized rolling wheel is arranged between the two hydraulic devices; each of the hydraulic devices comprises a rotating arm and a hydraulic rod; one end of each of the rotating arms is connected to the machine frame through a rotating shaft, and the other end of each of the rotating arms is connected with the front end of the corresponding hydraulic rod; the tail end of each of the hydraulic rods is connected to the machine frame through a rotating shaft to control the rotating route of the corresponding rotating arm through the corresponding hydraulic rod; a rolling shaft is arranged between the two rotating arms; and a pressurized rolling wheel is connected to the rolling shaft in a sleeving manner. According to the road leveling machine disclosed by the invention, the hydraulic devices are arranged on the two sides of the machine frame, and the pressurized rolling wheel is arranged between the hydraulic devices, so that the rising and the falling of the pressurized rolling wheel are driven by the hydraulic devices; while the road leveling machine works, the pressurized rolling wheel is driven to fall by the hydraulic devices to jack the grinding wheel and enable the pressurized rolling wheel to be in contact with the ground; and the contact area of the pressurized rolling wheel and the ground is reduced, so that the pressure intensity is substantially elevated, and the compacting effect is improved. The road leveling machine disclosed by the invention is suitable for large-scale popularization.
Description
Technical field
The present invention relates to engineering machinery field, in particular to a kind of road roller.
Background technology
Also known as packer.Road roller belongs to the category of road furniture in engineering machinery, is widely used in high-grade highway, ferrum
The embankment compacting operation of the Larger Engineering Projects such as road, airfield runway, dam, stadium, can roll sand, half viscosity and viscosity
Soil, subgrade stability soil and asphalt concrete pavement layer.With the mechanical action of gravity of itself it is adaptable to various compacting operation, make
It is rolled layer generation permanent deformation closely knit.The degree of rolling influences whether the maintaining in road surface later stage.Thus, roll effect for lifting
Really, people have carried out to the consolidation effect of quiet road roller studying it is believed that the weight increasing road roller can make the line pressure of road roller
Power increases, thus improving consolidation effect.Then, within the quite a long time, people are devoted to developing large-tonnage road roller,
Maximum rubber-tyred roller once weighed more than 200 ton.Structure bulky, with high costs, it is unfavorable for large-scale promotion.
Content of the invention
For the present situation of above-mentioned prior art, the technical problem to be solved is to provide a kind of control cost,
And the road roller that roll intensity can be substantially improved.
The present invention solves the technical scheme that adopted of above-mentioned technical problem:Road roller, including driving wheel, driver's cabin, machine
Frame and rolling wheel, described frame both sides are provided with hydraulic means, are provided with supercharging roller, described liquid between described two hydraulic means
Pressure device includes pivoted arm and hydraulic stem, and described pivoted arm one end is connected to frame by rotating shaft, the front end phase of the other end and hydraulic stem
Even, described hydraulic stem end is connected to frame by rotating shaft, with the rotating path by hydraulic stem control pivoted arm, described two turns
It is provided with roller bearing, described supercharging roller is socketed on described roller bearing between arm.
Further, it is interference fit between described supercharging roller and roller bearing.
Compared with prior art, the invention has the beneficial effects as follows:The present invention passes through to arrange hydraulic means in frame both sides,
Between hydraulic means, setting supercharging roller, drives the lifting of supercharging roller by hydraulic means;During work, driven by hydraulic means
Dynamic supercharging roller declines, and rolling wheel jack-up is contacted with ground by supercharging roller, due to reducing the contact area with ground,
Thus significantly lifting pressure, improve consolidation effect.The present invention designs, suitable large-scale promotion.
Brief description
Fig. 1 is the overall structure diagram of the present invention;
Fig. 2 is another overall structure diagram of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the skill embodiment in the embodiment of the present invention, rather than all
Embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art institute under the premise of not making creative work
The every other embodiment obtaining, broadly falls into the scope of protection of the invention.
As shown in Figure 1-2, road roller, including driving wheel 1, driver's cabin 2, frame 4 and rolling wheel 3, described frame 4 both sides set
There is hydraulic means, be provided with supercharging roller 6 between described two hydraulic means, described hydraulic means includes pivoted arm 7 and hydraulic stem
5, described pivoted arm 7 one end is connected to frame 4 by rotating shaft, and the other end is connected with the front end of hydraulic stem 5, described hydraulic stem 5 end
Frame 4 is connected to by rotating shaft, to control the rotating path of pivoted arm 7 by hydraulic stem 5, between described two pivoted arms 7, is provided with rolling
Axle, described supercharging rolling 6 wheel is socketed on described roller bearing.It is interference fit between described supercharging roller 6 and roller bearing.
During work, drive supercharging roller 6 to decline by hydraulic means, rolling wheel 3 jack-up is departed from ground, rolling wheel stops
Operation;Contacted with ground by supercharging roller 6, due to reducing the contact area with ground, according to:P=F/S, thus significantly
Lifting pressure, improves consolidation effect.The present invention designs, suitable large-scale promotion.
Off working state, the piston rod of hydraulic stem 5 is in contraction state, and supercharging roller 6 is vacantly shelved, and is now pressurized roller
6 are not involved in operation, are tentatively rolled by rolling wheel 3.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of the spirit or essential attributes of the present invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as limiting involved claim.
