Background technology
At present, vibratory roller is the key equipment of the constructions such as high-grade highway, dam, building operations, groove basis, pipeline backfill, and oscillating component is the key component of vibratory roller, and the mode of vibration of existing road roller all is to realize this purpose with oscillating column pump or motor mostly.And with oscillating column pump or motor not only take up room large and also cost high, but the road roller device of excitation all is upper type at present.In addition, existing vibrating device mostly utilizes the High Rotation Speed of eccentric shaft to realize vibration, has following defective: 1, starting the eccentric shaft running need to be than high pulling torque, when power section loads suddenly load large, excessive to the power section loss; 2, cut off behind the power because effect of inertia, eccentric shaft still can rotate the long period, can not realize immediately stopping vibration.
The utility model content
Technical problem to be solved in the utility model provides a kind of road roller device of excitation of electromagnetic clutch control, can be with the driving pump of the road roller power source as device of excitation, and the eccentric degree of eccentric starting of oscillation mechanism can change automatically with rotary speed, realize mild the startup, and quick failure of oscillation.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of road roller device of excitation of electromagnetic clutch control, comprise the power drive mechanism that is arranged on the road roller body and eccentric starting of oscillation mechanism, described power drive mechanism is by driving pump, power transmission shaft, electromagnetic clutch and drive pulley form, power transmission shaft is arranged in the bearing support on the body, the one end is connected with driving pump, the other end is connected with the clutch end cover of electromagnetic clutch, drive pulley is arranged on the electromagnetic clutch, and relative with clutch end cover, described eccentric starting of oscillation mechanism comprises eccentric starting of oscillation axle and driven pulley, eccentric starting of oscillation axle is arranged in the fixedly axle bed on the body, the one end is connected with driven pulley, driven pulley is connected with drive pulley by driving-belt, the axle body of described eccentric starting of oscillation axle is cylindrical, be provided with a chute with its axially parallel in the inside of axle body, the notch of chute is positioned on the side periphery of axle body, be provided with eccentric shoe in the chute, the bottom of eccentric shoe is connected with the bottom of chute by extension spring, when extension spring was in reset mode, the center of gravity of the eccentric starting of oscillation axle that eccentric shoe and axle body consist of was positioned on the axis of axle body.
The both sides of described eccentric shoe bottom are respectively equipped with projection, and the notch both sides of chute are provided with the card edge relative with projection.
The beneficial effects of the utility model are: with the driving pump of the road roller power source as device of excitation, realize conserve space, reduced the effect of cost, and simple structure, dependable performance, installation and maintenance is easy to maintenance.Electromagnetic switching clutch is closed under the general walk, power drive mechanism operation and eccentric starting of oscillation mechanism does not work, if during starting of oscillation, start then that electromagnetic switching clutch makes clutch end cover on the power drive mechanism and the drive pulley on the electromagnetic clutch through the electromagnetism adhesive and drive the operation of eccentric starting of oscillation mechanism by driving-belt, thereby realize vibration.When eccentric starting of oscillation mechanism off-duty, eccentric shoe in the eccentric starting of oscillation axle is in initial position under the effect of extension spring, this moment, the center of gravity of the eccentric starting of oscillation axle that eccentric shoe and axle body consist of was positioned on the axis of axle body, it is less to rotate the moment of torsion that needs, can under the drive of driving pump, start gently, reduce the loss of driving pump.After starting running, eccentric starting of oscillation axle rotating speed increases, eccentric shoe since centrifugal action to chute notch one Slideslip, thereby the offset of eccentric starting of oscillation axle is increased gradually, oscillation intensity also increases gradually.After eccentric starting of oscillation axle cuts off power, begin to reset gradually with the effect of Speed Reduction eccentric shoe owing to extension spring, the offset of eccentric starting of oscillation axle reduces, oscillation intensity also reduces gradually, therefore, although eccentric starting of oscillation axle of the present utility model also can continue to rotate certain hour after cutting off power, it vibrates and has eccentric shaft now obvious reduction, has realized quick failure of oscillation.

The specific embodiment
Specify by reference to the accompanying drawings embodiment of the present utility model.
A kind of road roller device of excitation of electromagnetic clutch control, comprise the power drive mechanism 2 that is arranged on the road roller body 1 and eccentric starting of oscillation mechanism 3, described power drive mechanism 2 is comprised of driving pump 4, power transmission shaft 5, electromagnetic clutch 6 and drive pulley 7, power transmission shaft 5 is arranged in the bearing support 8 on the body 1 by bearing, the one end is connected with driving pump 4 by terminal pad, and the other end is connected with the clutch end cover 9 of electromagnetic clutch 6 by locking nut.Drive pulley 7 is arranged on the electromagnetic clutch 6, and relative with clutch end cover 9, and when starting electromagnetic clutch, clutch end cover 9 can be with drive pulley 7 adhesive and rotated synchronously.Described eccentric starting of oscillation mechanism 3 comprises eccentric starting of oscillation axle 10 and driven pulley 11, and eccentric starting of oscillation axle 10 is arranged in the fixedly axle bed 12 on the body 1 by bearing, and the one end is connected with driven pulley 7, and driven pulley 7 is connected with drive pulley 7 by driving-belt 20.The axle body 13 of described eccentric starting of oscillation axle 10 is cylindrical, is provided with a chute 14 with its axially parallel in the inside of axle body 13, and the notch 15 of chute 14 is positioned on the side periphery of axle body 13.Be provided with eccentric shoe 16 in the chute 14, the under the action of the centrifugal 15 directions slip along chute to notch of this eccentric shoe.The bottom of eccentric shoe 16 is connected with the bottom of chute 14 by extension spring 17, and when extension spring 17 was in reset mode, eccentric shoe 16 was positioned on the axis of axle body 13 with the center of gravity of the eccentric starting of oscillation axle 10 that axle body 13 consists of.Therefore, under the state that eccentric starting of oscillation axle 10 stops, its center of gravity is off-axis not, and it is less to rotate the moment of torsion that needs.With the rotation of eccentric starting of oscillation axle 10, eccentric shoe 16 slides to notch 15 directions gradually, and the offset of eccentric starting of oscillation axle 10 increases gradually, and Oscillation Amplitude also increases gradually.When eccentric starting of oscillation axle 10 broke away from power source, rotating speed reduced gradually, and offset reduces gradually, and Oscillation Amplitude also reduces gradually.
