A kind of driving oscillating is pressed the road rammer compacter
One, technical field
The utility model belongs to technical field of engineering machinery.Relate in particular to a kind of vibratory roller tool.
Two, background technology
The vibratory roller that uses in civil engineering and road construction is well received with two good consolidation effects of mechanical pudding because of having pressure road (slow-witted weight is real).And the small vibrating road roller because of there not being the so huge volume body weight of road roller less, should produce dither, can produce good tamping effect and receive much attention sandy soil, rubble.
At present, vibratory roller mainly contains two kinds of forms: a kind of is fluid pressure type, as " series and parallel switch all-hydraulic full driving vibratory roller " (ZL02223227.3) and the Mikasa road roller made of Japanese three large bamboo hat with a conical crown and broad brim industry commercial firms, though tangible advantage is arranged, but complex structure, cost an arm and a leg maintenance difficult.Another kind is a mechanical type, and as " a kind of hand held vibratory roller " (ZL99233848.4), structure is also comparatively complicated, cost is high, volume is big; And for example " the road rammer compacter is pressed in the vibration of a kind of reversible " (ZL200420076062.2), though it is simple in structure, cost is low, easy to maintenance, volume is less, but, make application life, the energy-saving effect of vibrating motor be subjected to certain influence because of vibrating motor is installed in the central axis place of vibration roller by the output shaft two ends.
Three, summary of the invention
The purpose of this utility model provide a kind of not only simple in structure, cost is low, volume is less, easy to maintenance, consolidation effect good, and the driving oscillating of the long service life of rational in infrastructure, vibrating motor, energy conservation is pressed the road rammer compacter.
For achieving the above object, the technical scheme that the utility model adopted is: the front end in frame is equipped with vibration roller, the rear end of frame is equipped with driving wheel, the front and back end of frame connects with vibration damper plate by corresponding shock-absorbing spring, the rear end of vibration damper plate is hinged with the operation handrail, and the end of operation handrail is equipped with operating grip and junction box.Vibrating motor is installed in vibration roller, eccentric son is installed in the output shaft two ends of vibrating motor, vibrating motor is installed in the bottom of machine seat board, machine seat board is fixed on the inner end of the central axis of vibration roller, the central axis outer end of vibration roller is fixedly connected by rolling bearing and fixed bearing block, and the front end of fixed bearing block and frame is fixedly connected.The middle part of frame is equipped with drive motors, and drive motors is connected with driving wheel by transmission system, and driving wheel is through chain and the sprocket wheel link that is installed in vibration roller one end.
Above-mentioned machine seat board is a grooved, and grooved top is fixed on the inner end of the central axis of vibration roller.The power line of vibrating motor passes vibration roller by the centre bore of the central axis of vibration roller, is connected to junction box by frame, operation handrail again.The equal diameters of driving wheel and vibration roller.
Owing to adopt technique scheme, the utility model is not only simple in structure, cost is low, volume is less, easy to maintenance, consolidation effect good, and has rational in infrastructure, the long service life of vibrating motor, the characteristics of energy conservation.

Five, the specific embodiment
The utility model will be further described below in conjunction with embodiment:
A kind of driving oscillating is pressed the road rammer compacter, as shown in Figure 1 and Figure 2, at the front end of frame [3] vibration roller [5] is installed, and the rear end of frame [3] is equipped with driving wheel [12].Vibrating motor [17] is installed in vibration roller [5], eccentric son [19] is installed in the output shaft two ends of vibrating motor [17], vibrating motor [17] is installed in the bottom of machine seat board [18], and machine seat board [18] is a grooved, and the top of grooved is fixed on the inner end of the central axis [8] of vibration roller [5].Central axis [8] outer end of vibration roller [5] is fixedly connected by rolling bearing [24] and fixed bearing block [23].Fixed bearing block [23] is fixedly connected with the front end of frame [3], the front and back end of frame [3] connects with vibration damper plate [1] by corresponding shock-absorbing spring [2], the rear end of vibration damper plate [1] is hinged with operation handrail [16], and operation handrail [16] end is equipped with operating grip [15] and junction box [14].
The driving wheel [12] that install the rear end of frame [3] and the equal diameters of vibration roller [5].At the middle part of frame [3] drive motors [10] is installed, drive motors [10] is connected with driving wheel [12] by transmission system [13], driving wheel [12] is through chain [11] and be installed in sprocket wheel [6] link on the quill [7] of vibration roller [5] one ends, make vibration roller [5] realize two the driving, i.e. vibration roller [5] performance that has not only vibration but also roll.
The power line [22] of vibrating motor [17] passes vibration roller [5] by the centre bore of the central axis [8] of vibration roller [5], is connected to junction box [14] by frame [3], operation handrail [16] again.On near the frame [3] vibration roller [5] and the driving wheel [12], also be provided with cleaning shoe [4], [9].
The vibration roller of this device [5] is only done vibration and is pressed the road special use, and driving wheel [12] can be done to advance, retreat, but the usefulness on double as roll extrusion ground also; When stopping operation, driving wheel [12] can be used as wheel, the usefulness of cutting to.
When the vibrating motor [17] of this device rotated, the centrifugal force that eccentric son [19] produces was to the ground vibration tamping, and the component that advances that utilization produces makes vibration roller [5] rolling compacting forward; When centrifugal force produces the component retreat and since the rear end of the frame [3] of vibratory roller set transmission system [13], can not move the unidirectional operation of can only advancing backward because of its brake force.。
This specific embodiment is not only simple in structure, cost is low, volume is less, easy to maintenance, and have the long service life, energy conservation of rational in infrastructure, vibrating motor, the characteristics that consolidation effect is good.
