Description
Technical field
The utility model belongs to pavement engineering compacting machinary technical field, relates to a kind of oscillatory roller.
Background technology
In asphalt concrete pavement construction, degree of compaction is one of the key technical indexes of estimating construction quality of pavement.Usually the degree of compaction of asphalt concrete pavement mainly by double-steel wheeled vibratory roller and rubber-tyred roller alternately roll realize.From compaction theory, vibratory roller utilizes self gravitation to add exciting force and vertically acts on the pressurized ground surface material, the self gravitation that the rubber-tyred roller utilization is larger, the distortion of tire play the rubbing effect to the pressurized ground surface material, the two is used alternatingly vibratory roller and rubber-tyred roller, the mutual embedding of bituminous concrete aggregate is squeezed, be full of bituminous cements between the aggregate, just can reach the pavement compaction effect of expection.Oscillatory roller has appearred in the compacting along with the change of construction technology, particularly bridge, culvert tunnel asphalt concrete laying.Oscillatory roller is realized by the oscillating movement of synthesizing at fore-and-aft direction ovalize state of oscillation wheel circumference and axle core two directions, under the acting in conjunction of two kinds of modes of oscillation, aggregate is driven plain after rubbing, is full of bituminous cements between the aggregate, has strengthened texture density and the planarization of road table.Oscillatory roller has been taken into account the effect of double-steel wheeled vibratory roller and rubber-tyred roller.Particularly bridge and Around Buildings etc. can not use the place of vibratory roller, more outstanding its purposes and importance.But also there is the shallow defective of compacting depth in oscillatory roller, and traditional forward and backward steel wheel of oscillatory roller is oscillation wheel simultaneously, only is adapted to the compacting on bridge, culvert tunnel and thin-layer bituminous road surface, and equipment efficiency of usage is low.
The utility model content
The purpose of this utility model is to be to solve the defective that exists in the background technology, and the combined structure of a kind of oscillation wheel that provides and vibrating wheels and the oscillatory roller of applied range.
For realizing above purpose, the technical solution adopted in the utility model: a kind of oscillatory roller, it comprises front frame, rear vehicle frame, body cradle, hydraulic pressure and control system, it is characterized in that: be provided with motor, vibrating wheels and the drive disk assembly that is connected with motor in the front frame, the front frame top is provided with driver's cabin; Be provided with oscillation wheel in the rear vehicle frame; Front frame is connected by body cradle with rear vehicle frame.
In the present invention, described vibrating wheels involving vibrations wheel body, vibration exciter and vibrating motor; Described vibration exciter is that seven grades of width-adjustable are regulated major and minor eccentric block structure, and the axis of its major and minor eccentric shaft overlaps with the vibration wheel body centre of gyration; Vibrating motor is connected with the main eccentric shaft of vibration exciter by yielding coupling.
In the present invention, described oscillation wheel comprises vibration wheel body, vibration vibrator and vibration motor; Described vibration vibrator arranges four vibration eccentric shaft structures around the central axis equal angles, and the axis of central axis overlaps with the vibration wheel body centre of gyration; The central axis of vibration vibrator is connected with the vibration motor by yielding coupling.
In the present invention, described hydraulic pressure and control system are electric-hydraulic proportion control element and system.
The structure that the utility model employing oscillation wheel and vibrating wheels are combined, use oscillation wheel, vibrating wheels can be excited at the same time or oscillation wheel, the single control form of taking turns exciting of vibrating wheels, widened the scope of application of product, the improving product service behaviour, improved the utilization rate of equipment, reduced use cost, economic benefit is obvious.

Fig. 2 is the utility model vibrating wheels structural representation;
Fig. 3 is the utility model oscillation wheel structural representation.
In the drawings, 1, front frame; 2, body cradle; 3, rear vehicle frame; 4, oscillation wheel; 5, vibrating wheels; 6, driver's cabin; 7, vibration wheel body; 8, vibration exciter; 9, vibrating motor; 10, vibration wheel body; 11, vibration vibrator; 12 vibration motors; 13, central axis.
The specific embodiment
As shown in Figure 1, assembly relation of the present utility model is: be provided with motor, vibrating wheels 5 and the drive disk assembly that is connected with motor in the front frame 1, front frame 1 top is provided with driver's cabin 6; Be provided with oscillation wheel 4 in the rear vehicle frame 3; Front frame 1 is connected by body cradle 2 with rear vehicle frame 3; Hydraulic pressure and control system are electric-hydraulic proportion control element and system.
As shown in Figure 2, in the present invention, vibrating wheels 5 involving vibrations wheel bodys 7, the vibrating motor 9 that vibrating wheels 5 vibrative vibration exciters 8 and driving vibration exciter 8 are moved; Described vibration exciter 8 is that seven grades of width-adjustable are regulated major and minor eccentric block structure, and the axis of its major and minor eccentric shaft overlaps with vibration wheel body 7 centres of gyration; The main eccentric shaft of vibration exciter 8 is connected with vibrating motor 9 by yielding coupling.
As shown in Figure 3, in the present invention, oscillation wheel 4 comprises vibration wheel body 10, makes oscillation wheel 4 produce the vibration vibrator 11 of vibration and the vibration motor 12 of driving vibration vibrator 11 motions; Described vibration vibrator 11 arranges four vibration eccentric shaft structures around central axis 13 equal angles, central axis 13 is the power input shaft of vibration vibrator 11, the axis of central axis 13 overlaps with vibration wheel body 10 centres of gyration, transmits rotating torque by synchronous belt between central axis 13 and four vibration eccentric shafts; The central axis 13 of vibration vibrator 11 is connected with vibration motor 12 by yielding coupling.Four vibration eccentric shaft synchronous rotaries produce the eccentric force formation alternate torque that is parallel to each other makes vibration wheel body 10 produce oscillating movements.
The hydraulic pump of motor driven hydraulic system produces hydraulic oil, and pressure oil drives respectively vibration motor 12, vibrating motor 9, driving motors and steering gear.
Control system is by to the control of hydraulic system, realizes that oscillation wheel 4, vibrating wheels 5 are excited at the same time that compacting work or oscillation wheel 4, vibrating wheels 5 are single takes turns Excitation Compaction work, and the work that realizes road roller is travelled and turned to.
In the oscillation wheel of tradition oscillatory roller, only have two vibration eccentric block rotating Vortexes, therefore the steel wheel axle is produced a moment; Four eccentric blocks are arranged in the oscillation wheel of oscillatory roller of the present utility model.Whenever rotate a circle, moment changes the direct action direction, thereby causes the level vibration of steel wheel, and horizontal force passes to the road surface from steel wheel.Under less compacting counting, can obtain better consolidation effect like this, the vibration effect of driver and surrounding environment is also reduced greatly.
More than a kind of oscillatory roller provided by the utility model is described in detail, herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
