Fig. 2 is the structural representation of control system second embodiment of concrete mixer truck;
Fig. 3 is that the described control system of Fig. 1 is applied in the structural representation on the concrete mixer truck.
The specific embodiment
Consult Fig. 1, the control system 1 of concrete mixer truck of the present invention comprises: a control box 11, a stepper motor 12 and an oil pump 13.Control box 11 is connected by wired or wireless electric connection mode with stepper motor 12.Stepper motor 12 is installed on the fixing support 123, and it comprises an output shaft 121, and oil pump 13 comprises a fork 131, and stepper motor 12 is connected with fork 131 by transmission mechanism.Transmission mechanism comprises first belt pulley 122 that is arranged on stepper motor 12 output shafts 121, the belt 124 that is arranged on second belt pulley 132 on the fork 131 and connects first, second belt pulley 122,132.
Control system 1 in the present embodiment is when work, by control box 1 control step motor 2 realize just changeing, counter-rotating etc. rotatablely moves, driving fork 131 by stepper motor 2 by belt 124 is more just changeing, is reversing, and then the fuel-displaced direction of control oil pump 13 changes, how many fuel-displaced of oil pump 13 can handle the anglec of rotation realization that stepper motors 12 are adjusted belt pulley 122,132 by control box 11.
Hydraulic shock occurs when forward and reverse fuel-displaced switch and influence service life of oil pump 13 for fear of oil pump 13, on stepper motor 12, also be provided with the sensor of a sensing stepper motor 12 metas, when stepper motor 12 runs to meta, oil pump 13 is in zero-bit, at this moment, sensor sends sensing signal and gives control box 11, changed course rotation again after being controlled stepper motor 12 and postponed to pause when the meta by control box 11.
Fig. 2 is the structural representation of control system second embodiment of concrete mixer truck; The control system 1 ' of concrete mixer truck of the present invention is basic identical with the foregoing description, different is, transmission mechanism comprises in the present embodiment: be arranged on one first gear 122 ' and one second gear 132 ' that is arranged on the fork 131 on the output shaft 121, this first, second gear 122 ', 132 ' is meshing with each other, and preferred two gears 122 ', 132 ' are sector structure.
Control system 1 ' in the present embodiment is when work, realize that by control box 11 control step motors 12 just commentaries on classics, meta, counter-rotating etc. rotatablely move, drive 131 rotations of oil pump 13 forks by stepper motor 12 by first, second gear 122 ', 132 ' then, and then control oil pump 13 forwards are fuel-displaced or oppositely fuel-displaced, and the big I of oil pump 13 oil pump capacity handles by control box 11 that stepper motors 12 are adjusted first, second gear 122 ', 132 ' the anglec of rotation realizes.
Fig. 3 is that the control system 1 among above-mentioned first embodiment is applied in the structural representation on the concrete mixer truck 2, as described in Figure, tank body 23 is driven by driving mechanism 22 and realizes rotation, driving mechanism 22 can be hydraulic motor and reductor etc., the fuel-displaced direction of oil pump 13 directly influences the direction of rotation of hydraulic motor, and the size of oil pump oil pump capacity also directly influences the rotating speed of hydraulic motor.The oil pump 13 of control system 1 links to each other with the hydraulic motor of the driving mechanism 22 of concrete mixer truck.The operation principle of this trucd mixer 2 is: the initial position of stepper motor 12 is at meta, handling stepper motor 12 by control box 11 is just changeing, and by belt 124 transmissions drive the fork 131 of oil pump 13 equidirectional just changeing so that forward bias from zero-bit, this moment, oil pump 13 forwards were fuel-displaced, and then hydraulic motor is rotated in the forward, the final tank body 23 that drives is realized just changeing, thereby realizes the charging and the agitating function of tank body 23.Rotating speed when tank body 23 is just changeing and optional position adjustment can be handled stepper motor 12 by control box 1 and realize; When tank body 23 pre-counter-rotating dischargings are operated, handle stepper motor 2 by control box 1 and change counter-rotating into from just changeing, fork 131 reverses and deflection angle is diminished gradually, the oil pump capacity of oil pump 13 also diminishes gradually, when fork 131 was got back to zero-bit, oil pump 13 stopped fuel-displaced, rotated to reverse directions after stepper motor 12 is had a break again, to avoid oil pump 13 hydraulic shock that high pressure is changed to occur, improve the service life of oil pump 13 and hydraulic motor.Tank body 23 counter-rotating rotating speeds and optional position adjustment can be handled the oil pump capacity realization of oil pump 13 by control system 1.
