Description
Technical field
The utility model relates to a kind of vibration control apparatus of self-propelled roller.
Background technology
The vibrational system of self-propelled roller has closed system and open system dual mode; Open system generally adopts the mode of manual operation vibrating valve to realize that the road roller height shakes and hangs down the unlatching and the conversion of shaking at present; Long, height of time that has that system's starting of oscillation overshoot is big, breath the shakes problems such as the no automatic delayed of state conversion of shaking cause the damage of hydraulic system element easily.
Fig. 1 shakes and hangs down the unlatching of shaking and the system drawing of conversion for the existing mode that adopts manual vibrating valve realizes the height of road roller.
As shown in the figure, after the road roller starting, when manually the handle of vibrating valve 1 is in the meta state, the road roller friction.Upwards promote the handle of manual vibrating valve 1; Handle is in the low position that shakes, and oscillating column pump 4 flows to the A mouth of vibrating motor 2 from the hydraulic oil of 5 li suctions of the fuel tank position, a left side through manual vibrating valve 1; B mouth through vibrating motor 2 after manually vibrating valve 1 get back to fuel tank 5 with oil filter 3, realize the low industry of bestirring oneself.When manually the handle of vibrating valve 1 was got back to the meta state, oscillating column pump 4 was directly got back to fuel tank 5 through oil filter 3, the road roller friction from the hydraulic oil of 5 li suctions of the fuel tank meta through manual vibrating valve 1.Promote the handle of manual vibrating valve 1 downwards; Handle is in the height position that shakes, and oscillating column pump 4 flows to the B mouth of vibrating motor 2 from the hydraulic oil of 5 li suctions of the fuel tank right position through manual vibrating valve 1; A mouth through vibrating motor 2 after manually vibrating valve 1 get back to fuel tank 5 with oil filter 3, realize the high industry of bestirring oneself.Handle shakes from height, and to get back to meta identical with state when meta is got back in the low position that shakes in the position.
Adopt the mode of manual vibrating valve to realize that the height of road roller shakes and hangs down the unlatching of shaking and conversion and can realize that road roller the shake conversion, Gao Zhen of industry, height of just bestirring oneself stops, hanging down the hold function of shaking, but shortcoming is: 1. road roller starting of oscillation overshoot is big; 2. it is long that road roller ceases the time of shaking; 3. height shakes and changes no delay function, and is bigger to the Hydraulic Elements infringement.
Therefore, the shake open type vibration control system of transformation energy automatic delayed of adjustable, height of time that works out that a kind of starting of oscillation overshoot is little, breath shakes is those skilled in the art's technical issues that need to address.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of road roller open type vibration control system, long, height of this system has solved that road roller open type vibrational system starting of oscillation overshoot is big, breath the shakes time no latency issue of conversion of shaking.Overshoot is little when having starting of oscillation, and the pressure loss is little, and the breath adjustable advantage of time of shaking has also effectively protected the hydraulic system element to avoid impact damage simultaneously.
The technical scheme of the utility model is: this road roller open type vibration control system; Comprise the ZDKZ012 vibrating controller; The I1 of vibrating controller, I2, Q3 pin link to each other with vibroswitch; The Q1 of vibrating controller, Q2, Q3, Q4, Q5, Q6, Q7, Q8 pin are corresponding continuous with shake portable lamp, electromagnetic valve A electromotion pilot lamp, electromagnetic valve B electromotion pilot lamp, electromagnetic valve C electromotion pilot lamp, electromagnetic valve D electromotion pilot lamp of the low portable lamp that shakes, meta indicator lamp, height respectively; Order is serially connected with electromagnetic valve D, electromagnetic valve B between the Q9 of vibrating controller and the Q12 pin; Order is serially connected with electromagnetic valve C, vibrating motor, electromagnetic valve A between the Q10 of vibrating controller and the Q11 pin, and electromagnetic valve A links to each other with fuel tank 5 through electromagnetic valve B, oscillating column pump in proper order, and electromagnetic valve C links to each other with fuel tank through electromagnetic valve D, oil filter in proper order.
Shake portable lamp, electromagnetic valve A electromotion pilot lamp, electromagnetic valve B electromotion pilot lamp, electromagnetic valve C electromotion pilot lamp, electromagnetic valve D electromotion pilot lamp of the low portable lamp that shakes, meta indicator lamp, height is installed on the surface of vibrating controller, uses light emitting diode.Vibroswitch provides input signal, and vibrating controller output control electromagnetic valve and indicator lamp are realized unlatching that road roller just shakes, stop and change, and the shake time-delay control of conversion of height, and the time is adjustable, has indicator lamp to indicate simultaneously.Vibroswitch pushes lowly when shaking the position from the height position that shakes, and electromagnetic valve A cuts off the power supply immediately, electromagnetic valve D energising outage after 4 seconds, electromagnetic valve B energising simultaneously.Vibroswitch pushes height when shaking the position from the low position that shakes, electromagnetic valve B cuts off the power supply immediately, electromagnetic valve C energising outage after 4 seconds, electromagnetic valve A energising simultaneously.
