The vertical oscillatory type road roller is suitable for various fields with limited compacting environment conditions and solves the difficult problems that under the working conditions that a water stable layer with big thickness is paved, high embankments are intensified, and the like, the compacting force demand is big, the compacting depth is deep, the compacting degrees of the upper surface and the lower surface are even, and simultaneously the surface level degree demand after compacting is high.
Description
Technical field
The utility model relates to a kind of road construction machinery, particularly relates to a kind of vertical vibration formula road roller.
Background technology
Domestic and international employed vibratory roller can be divided into towed vibratory roller, self-propelled single vibratory road roller and double-steel wheeled vibratory roller three major types.Their common eccentricity excitation characteristics are to adopt with body concentric single shaft of vibrating wheels or multiaxis drive eccentric vibrator to move in a circle, eccentricity excitation power that produces and the vibration wheel body that causes motion all are that circumferencial direction is uniform, will produce the high frequency rubbing to the material of surface layer in the time of compacting.Towed vibratory roller, self-propelled vibratory roller are mainly used in basis compaction, are characterized in that eccentricity excitation power is big, compacted depth is big; Shortcoming is that compacting surface is destroyed greatly, so be not suitable for being used for the surface layer compacting.Double-steel wheeled vibratory roller is mainly used in the surface layer compacting, is characterized in that compacting surface is smooth; Shortcoming is that eccentricity excitation power is little, and compacting depth is little, and compacting depth in actual applications is less than 200mm.At present, at home in the highway construction, in order to improve highway intensity, accelerating construction progress, a large amount of big thickness that adopt empty shop 400-600mm technology that paves when the steady layer of water paves needs the road roller of super large eccentricity excitation power type could compacting, and the steady layer of water belongs to a surface layer and paves simultaneously, very high to the surface finish requirement, and the surface layer particle can not be destroyed.In addition, in southern china road design and construction, high embankment structure is adopted in many places, in its compaction process standard, must carry out the reinforcement compacting, the common road roller compacting degree of depth is not enough, non-round impact roller needs tractor traction work, turning radius is very big, does not fit into the reinforcement compacting of short distance, small size, and shock compaction simultaneously causes the road surface to form the dell of discontinuity, the surface is destroyed, compacting is inhomogeneous, has only zap pit part degree of compaction big, and destroys serious to the basis and the bridges and culverts of weak subgrade embankment.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, a kind of compacting depth is provided and influences the degree of depth big, and the compacted lift compactness is even, compacting surface is smooth smooth, the car load maneuverability, the compacting of can fixing a point, the vertical vibration formula road roller that not influenced by the work-yard size.
The technical solution of the utility model is: a kind of vertical vibration formula road roller, comprise vehicle frame, and it is characterized in that: be positioned at vehicle frame and rotate the vibration wheel body that is provided with by drive motor, be provided with the vibratory chamber that drives by vibrating motor in the described vibration wheel body.
The utility model compared with prior art has the following advantages: design feature of the present utility model is on the basis of vertical vibration at home and abroad, directional vibration principle and teaching material theory, by adopting huge revolving bearing, high-performance yielding coupling, simplified the exciting drive mechanism, reduce cost of production, guaranteed the vibrating mechanism quality of stability.Its work characteristics is that compacting depth can reach 500mm, influences the degree of depth greater than 2000mm, and the compacted lift compactness is even, and compacting surface is smooth smooth, the complete machine maneuverability, and the compacting of can fixing a point is not subjected to the influence of work-yard size.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the syndeton schematic diagram of the utility model vehicle frame 1, vibration wheel body 4 and vibratory chamber 3.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises vehicle frame 1, is positioned at vehicle frame 1 and rotates the vibration wheel body 4 that is provided with by CD-ROM drive motor 13 drivings, is provided with the vibratory chamber 3 that drives by vibrating motor 6 in the described vibration wheel body 4.
The right-hand member of described vibratory chamber 3 radially is connected with vibration wheel body 4 by bearing 12; The left end of vibratory chamber 3 radially is connected with vibration wheel body 4 by floating bearing 8, axially is connected with frame 1 by shock absorber 2.
One end of described vibration wheel body 4 is connected with CD-ROM drive motor 13 by shock absorber 2, and CD-ROM drive motor 13 is fixedlyed connected with vehicle frame 1.
Two groups of vibrators 11 have been horizontally disposed with in the described vibratory chamber 3, two groups of vibrators 11 are installed in respectively in the rotating shaft 14 and No. two rotating shafts 15 that be arranged in parallel, a rotating shaft 14 is connected with driving gear set 9 by the yielding coupling 10 that is installed in its end with No. two rotating shafts 15, and described driving gear set 9 is connected with vibrating motor 6 by motor shaft coupling 7.
Described driving gear set 9 comprises two gears compositions that the number of teeth is identical, direction of rotation is opposite.
The utility model operating principle is as follows:
During the utility model work, drive 4 rotations of vibration wheel body by CD-ROM drive motor 13 and realize walking.The left side of vibratory chamber 3 connects with vehicle frame 1 left side by shock absorber 2, and vibratory chamber's 3 relative vehicle frames 1 maintain static in the process of moving.Vibration wheel body 4 is connected with bearing 12 by floating bearing 8 with vibratory chamber 3, and both rotate when complete machine travels relatively.Be horizontally installed with two groups of vibrators 11 and driving gear set 9 thereof in the vibratory chamber 3 relatively, vibrating motor 6 links to each other with driving gear set 9 by motor shaft coupling 7, driving gear set 9 links by the vibrator 11 of yielding coupling 10 and two groups of symmetries again, every group of vibrator can be 1, also can be 2, the vibrator internal construction can be fixed, also can be movable to realize two grades of vibrations.The rotation of vibrating motor 6 outputs finally is converted into the anti-phase rotation of constant speed of two groups of vibrators 11 like this, because two groups of vibrator horizontal symmetrical are installed, the horizontal direction active force is offset fully, finally by vibrating wheels output vertical vibration active force.
Vibration wheel body 4 connects with the vibratory chamber big floating bearing 8 of 3 usefulness, could realize vibrating motor 6 like this and vibrate the installation of wheel body 4 large eccentricities, and vibrating motor 6 is coaxial with a gear in the driving gear set 9.
The supporting form of driving gear set 9 for each gear with two bearings symmetry mounting supports, thereby make gear meshing precision height, strength of gear is good, long service life.
Because driving gear set 9 is connected with vibrator 11 by yielding coupling 10, rotating shaft has guaranteed the accuracy of mesh and the application life of driving gear set 9 because of the high frequency radial swing that play produces can not produce any influence to driving gear set 9.
