Abstract
The utility model discloses an automatic vibrating and sprinkling system for a road roller, which is applied to the road roller with double steel wheels. The system comprises a controller, a signal processing circuit, a speed sensor, a vibration changeover switch, a sprinkling changeover switch, a vibration solenoid valve, a sprinkling pump and a storage battery. In the mode of automatic vibrating and sprinkling, the signal processing circuit transmits a signal of the speed sensor to the controller after processing and amplifying the signal; when the speed signal is calculated and processed to reach a preset parameter, the output end of the controller controls a water pump and the vibration solenoid valve to switch on. When the speed signal is smaller than the preset parameter, the output end of the controller controls the water pump and the vibration solenoid valve to switch off, so as to realize the automatic vibrating and sprinkling of the road roller. The controller can change the set value of the speed through modifying a pulse parameter, so that operating requirements of various road rollers on the automatic vibrating and sprinkling system can be met.
Description
Technical field
The utility model relates to the vibration of dual-steel wheel road roller and the control technology of watering aspect.
Background technology
Road roller belongs to the category of road furniture in engineering machinery, can be divided into several types such as static pressure type road roller, vibrating roller, impact roller according to compaction theory.Double-steel wheeled vibratory roller belongs to the vibrating roller type, mainly is flexible pavement is carried out compacting.Automatically vibration and sprinkle water function are one of its main functions, i.e. road roller vibration and watering automatically when reaching predefined speed do not need to go frequent action button and switch again, and main effect is the labour intensity that reduces the operator.Generally adopt handle contacting travel switch connection circuit to realize at present.
Please refer to Fig. 1, Fig. 1 realizes the system circuit diagram of vibration automatically and watering for the mode of existing employing handle contacting travel switch.
As shown in the figure, at first vibration changeover switch (3) and watering changeover switch (6) are chosen in the Z terminal, be under the automatic mode, after control crank (2) promotes a segment distance forward or backward, travel switch (1) closure, vibration electromagnetic valve (4) and watering pump (5) are charged, and road roller begins to realize vibration and watering.
Adopt the mode of control crank contacting travel switch can realize road roller vibration and watering automatically, but shortcoming is: 1. the distance of handle promotion is difficult to set, and needs debugging repeatedly just can find this distance, and inaccuracy.2. the distance that different types promotes is different, must set respectively, very trouble.3. the installation inconvenience of travel switch, and easy becoming flexible.So just cause with the starting of oscillation and the watering speed of a collection of road roller different, also unstable.
Therefore, work out and a kind ofly debug simple and convenient, control accurately and to satisfy automatic vibration and the sprinkler system that different type of machines uses simultaneously be those skilled in the art's technical issues that need to address.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of road roller vibration and sprinkler system automatically, is used for double-steel wheeled vibratory roller.It is characterized in that: system is made up of controller, signal processing circuit, velocity sensor, vibration changeover switch, watering changeover switch, vibration electromagnetic valve, watering pump, storage battery.The L+ terminal of controller links to each other with positive and negative poles of battery respectively with the M terminal.The input of controller links to each other with signal processing circuit, and output links to each other with vibration changeover switch and watering changeover switch.Change the speed of road roller watering unlatching and starting of oscillation by the pulse parameter that changes controller.The signal processing circuit major function is that sensor circuit is handled amplification, so that controller can be discerned and gather.Under automatic vibration and watering pattern, signal processing circuit is transferred to controller after speed sensor signal is handled amplification, and through computing, when reaching preset parameters, the output of controller just control of pump is opened with the vibration electromagnetic valve.During less than preset parameters, the output of controller just control of pump stops with the vibration electromagnetic valve, thereby realizes the automatic vibration and the watering of road roller.Controller can change speed setting value by revising pulse parameter, can control the double-steel wheeled vibratory roller of different model easily accurately and realize vibration and sprinkle water function automatically.So just can satisfy the instructions for use of many kinds road roller.

The specific embodiment
The utility model provides a kind of road roller vibration and sprinkler system automatically, is used for double-steel wheeled vibratory roller, can realize double-steel wheeled vibratory roller vibration and sprinkle water function automatically easily accurately.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2, Fig. 2 is a kind of road roller provided by the utility model vibration and sprinkler system circuit diagram automatically; System is made up of controller (8), signal processing circuit (9), velocity sensor (10), vibration changeover switch (3), watering changeover switch (6), vibration electromagnetic valve (4), watering pump (5), storage battery elements such as (7).The L+ terminal of controller (8) links to each other with the both positive and negative polarity of storage battery (7) respectively with the M terminal.The input I5 of controller (8) links to each other with signal processing circuit (9), and output Q1 terminal links to each other with vibration changeover switch (3) Z terminal, and output Q2 terminal links to each other with watering changeover switch (6) Z terminal.Change the speed of road roller watering unlatching and starting of oscillation by the pulse parameter that changes controller (8).Signal processing circuit (9) major function is that sensor circuit is handled amplification, so that controller (8) can be discerned and gather.Signal circuit (9) is made up of triode (12), resistance R 1 (11) and R2 (13), please refer to Fig. 3.
When double-steel wheeled vibratory roller is worked, at first to get to the Z terminal to vibration changeover switch (3) and watering changeover switch (6), it is the position of automatic mode, velocity sensor (10) spreads out of sinusoidal signal or square-wave pulse signal, be transferred to the input of signal processing circuit (9) through lead, be processed into the strong signal of square-wave pulse after its output is transferred to 15 ports of controller (8), controller calculates and handles according to internal processes, after reaching the preset parameters value, output Q1 and Q2 have signal output, through vibration changeover switch (3) and watering changeover switch (6) back control vibration electromagnetic valve (4) and water pump (5).After the preset parameters value, output Q1 and Q2 no signal output vibration electromagnetic valve (4) and water pump (5) are not worked.The automatic vibration and the sprinkle water function of road roller have so just been realized.
