Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, the intelligent hydraulic drive control system is made up of hydraulic constant velocity valve and velocity sensor, control unit etc..Hydraulic constant velocity valve is connected with hydraulic variable displacement pump (plunger displacement pump), and velocity sensor is connected with motor, and the data wire of sensor and constant speed valve connects eight to control unit.Its operation principle is：When the rotating speed of automobile engine changes during transport, the hydraulic variable flow revolution speed being connected with it also changes therewith, now driving the motor rotary speed of tank body rotation will also change, velocity sensor on motor is connected to by velocity variations signal transmission to control unit, control is arranged on the constant speed valve events on hydraulic variable displacement pump to control unit immediately again, hydraulic pump swash plate angle is automatically adjusted, its output flow is kept constant, so that the rotating speed of mixing drum and driving power keep constant.
Hydraulic control system uses bussing technique, by way of master ＆ slave control, using CAN fieldbus as communication bus.The control system of hydraulic support receives the parameter information at scene by many level sensors, and the supporting state of support is monitored in real time, controls the position of piston rod so that support can control that completion is tried to stop people from fighting each other and automatic pushing and sliding etc. are operated by command adapted thereto.The controller of support is the core of whole control system, is mainly made up of microprocessor, data acquisition unit, operation device etc., according to the programmed instruction of setting, each work condition state of analysis and control support.
In order to ensure the quality of concrete in conveying way, the mixing drum of the fully loaded ready-mixed concrete of concrete mixing and transporting car must all be rotated in whole transportation, when agitator truck is with economy cruising, the need for the rotating speed of engine conforms exactly to mixing drum, but engine speed is improved in upward slope or starting, oil pump then scales up fuel delivery, thus can consume extra power.This can bring about the problem of several aspects：One driving performance for being reduction of agitator truck；Two are the increase in fuel consumption, cause certain economic loss, so as to increased operating cost；Three discharges for being the increase in carbon, also just increase the pollution to environment.When agitator truck is in charging, discharging, the engine long time is with idle running, the rotating speed of mixing drum is well below normal speed of agitator, thin cement slurry is easily separated out from bottom in concrete mix, and concrete also because losing slurry and aggregate exposure, segregation phenomenon occurs, then its cohesiveness declines, the mixing quality of concrete will be directly affected, the quality of engineering will be so influenceed, quality accident is easily caused.
In order to solve this problem, it is accomplished by hydraulic system and ensure that the speed of agitator of mixing drum must keep constant, do not influenceed by the change of automobile engine working speed, i.e. speed of agitator is unrelated with the speed of travel of vehicle, to avoid transportation ox from occurring making the frequent change of car speed cause the speed of agitator of mixing drum fluctuated because road conditions change, cylinder inner concrete flowing is uneven, produces serious isolation and slump is become big, destroys the problem of concrete quality.
Concrete mixing and transporting car realizes that the operation principle of stirring is to take out the power of automobile chassis by power transmission shaft, and the hydraulic variable displacement pump of drive hydraulic system principle, mechanical energy is converted into hydraulic energy and passes to fixed displacement motor, motor drives reductor again, agitating device is driven to rotate by reductor, so as to realize being stirred the concrete in agitating device.
