Abstract

The utility model relates to an improved construction machine. The road roller utilizing static function in the prior art has low compacting efficiency, and the road roller is not suitable for compacting roads made of cement. The utility model changes a front wheel utilizing the prior art into a vibrating wheel, and simultaneously the utility model has static line pressure and movable line pressure. The capability of compaction is increased by two times. A rigid machine frame is added with a two-stage device for damping vibration. A small box body is added between a gearbox and a side driving device, and a double-gear is arranged in the small box body. An engaged inner gear and a speed reduction gear are arranged to cause the driving device to adapt different rolling speed requirements of the roads made of bitumen and cement.

Description

Vibration road roller

The utility model relates to a kind of building machinery, is applicable to the road compacting.

6-8 ton and 8-10 ton tandem type road rollers and 12-15 ton three-roll road roller are the road compacting machinaries that the fifties Global Access is used, former quiet action type road roller, the weight of 60-70% concentrates on trailing wheel and plays compaction, 30-40% weight concentrates on front-wheel and plays guiding and transmit the effect of dead line pressure, efficient only is with 1/3 of tonnage vibrating roller, during work, have only 2,4 kilometer/hour two retaining speed, be only applicable to compacting asphalt, three-roll road roller is by the trailing wheel compacting, and ground is high between two trailing wheels after pressing rises into convex shape, lean on trailing wheel to stagger repeatedly and roll and could flatten.

The purpose of this utility model is to improve above-mentioned weak point in the prior art and a kind of improvement product is provided, change the prior art front-wheel into vibrating wheels, realize transmitting simultaneously the compacting functions of dead line pressure and moving-wire pressure, significantly improve compaction capacity, improve transmission device and make it to adapt to the friction speed requirement that pitch and cement pavement roll.

The utility model compared with prior art, has following advantage: 40 kilograms centimetres of moving-wire pressure that increased front-wheel, compaction capacity improves more than two times, improved transmission device, can be used for rolling cement pavement, recondition expense 5000-8000 unit, it only is below 1/3 of prior art manufacturing cost, for three-roll road roller, the utility model reaches the front and back wheel linear pressure and equates, large tracts of land flattens the road surface but just only need back and forth roll.

Task of the present utility model is finished by following approach, transform front-wheel as vibrating wheels, has increased the two-stage vibration absorber on rigid mounting, improves transmission system, has increased by two low travel speeds.

The utility model has following accompanying drawing:

Fig. 1 is the utility model 6-8 ton and 8-10 ton type sketch, (1) vibrating wheels wherein, (2) reducer, (3) fuselage, (4) fork foot, (5) driving wheel;

Fig. 2 is the utility model 12-15 ton type sketch, (1) vibrating wheels wherein, (3) fuselage, (4) fork foot, (5) driving wheel;

Fig. 3 is the partial sectional view of the utility model vibrating wheels, (8) one-level damping block wherein, (9) secondary damping block, (10) three grades of damping blocks;

Fig. 4 plays vibrating system for the utility model hydraulic pressure, (11) fuel tank wherein, and (12) oil pump, (13) hand control valve, (14) oil motor, (15) eccentric shaft, double dot dash line is depicted as eccentric block (removing);

Fig. 5 is the utility model speed reduction gearing, and wherein (16) band meshes internal gear, (17) duplicate gear, (18) reduction gearing;

Fig. 6 is the utility model oil pump installation drawing, (19) camshaft wherein, (20) injection pump, (21) driving gear, (22) oil pump.

The utility model will be described in further detail in conjunction with the embodiment in the above accompanying drawing, change the prior art front-wheel into vibrating wheels, as Fig. 4, drive oil pump (12) with motor, drive oil motor (14) by hand control valve (13), and make eccentric shaft (15) drive the eccentric wheel high-speed rotation, produce big centrifugal force and cause full wheel vibration, installation site such as Fig. 6 of oil pump (12), increase an output shaft that drives by bent axle in the delivery outlet position of motor band water pump, oil pump (12) is installed, the utility model vibration absorber such as Fig. 3, because it is very high that the utility model adopts the rigid connection vibration damping to require, so adorned on deceleration jerks (8) basis in prior art, between fork foot (4) and framework, increase second level damping block (9), on the vertical shaft between fork foot and the frame, increased third level damping block (10) again, former like this rigid mounting structure is constant, effectiveness in vibration suppression is still very good, the utility model speed reduction gearing such as Fig. 5, between prior art gearbox and side transmission, increased a small box, when duplicate gear (17) during at shown position road roller be in neutral gear, as handle shift fork and duplicate gear (17) is turned left stir, make it and be with engagement internal gear (16) engagement, the speed of travel of the present utility model keeps 2 of prior art, 4 kilometers/hour, be applicable to the rolled asphalt road surface, turned right when duplicate gear (17) and stir and reduction gearing (18) when engagement that the speed of travel of the present utility model can obtain 0.7,1.4 kilometer/hour, be applicable to and roll cement pavement.

The also available above technical scheme transformation of the quiet action type road roller of three-wheel, principle, structure are in full accord.

The utility model is applicable to the quiet action type road roller of the different model technological transformation that each factory of the whole nation produces.
