In technique scheme, the first proximity switch 1 and the 3rd proximity switch 3 are oppositely arranged, and can be arranged at respectively above and below reductor 12, and the second proximity switch 2 and the 4th proximity switch 4 are oppositely arranged, and can be arranged at respectively above and below bunker mechanism 10.
In technique scheme, relay comprises the first relay 5, second relay 6, the 3rd relay 7 and the 4th relay 8, first relay 5, second relay 6, the 3rd relay 7 and the 4th relay 8 and is electrically connected with the first proximity switch 1, second proximity switch 2, the 3rd proximity switch 3 and the 4th proximity switch 4 respectively.In addition, one end of first relay 5, second relay 6, the 3rd relay 7 and the 4th relay 8 is electrically connected formation one loop successively, specifically, the first relay 5, second relay 6, the 3rd relay 7 are electrically connected successively with one end of the 4th relay 8, form supply line.It should be noted that, relay can be contact relay, can also be the relay of other type, not do concrete restriction at this.
Induction installation is for detecting the position residing for mixing drum 11 and bunker mechanism 10, for induction installation, in one embodiment, induction installation is sensing chip, specifically, sensing chip comprises the first sensing chip and the second sensing chip, and the first sensing chip is for being arranged at the front portion of mixing drum 11, and the second sensing chip is for being arranged at the bunker mechanism 10 at mixing drum 11 rear portion.In another kind of embodiment, induction installation can also be transducer, and particularly, transducer is angular displacement sensor or obliquity sensor, when selecting angular displacement sensor, the installation site of angular displacement sensor need be on the rotation of mixing drum 11 front end or rear end; When selecting obliquity sensor, its installation site need perpendicular on the vertical line of the rotation of mixing drum 11 front end or rear end.
As shown in Figure 2, jockey 13 is also provided with between mixing drum 11 and bunker mechanism 10, jockey 13 is for connecting mixing drum 11 and bunker mechanism 10, jockey 13 is provided with latch and jack, one end of latch is provided with drive unit, specifically, drive unit can be oil cylinder, also can be cylinder, be provided with piston rod in oil cylinder or cylinder, one end of piston rod is connected with latch, when piston rod moves, latch can be promoted move in jack, thus realize the locking of mixing drum 11 and bunker mechanism 10 or be separated.In trucd mixer haul process, mixing drum 11 and bunker mechanism 10 lock, mixing drum 11 can with bunker mechanism 10 synchronous rotary.In trucd mixer charging or discharge process, mixing drum 11 is separated with bunker mechanism 10, and mixing drum 11 and bunker mechanism 10 can not synchronous rotaries.
In technique scheme, centering control system also comprises the indicator light for preventing misoperation, and indicator light is arranged at position trucd mixer being convenient to observe, its quantity can be multiple, when the proximity switch conducting of correspondence, indicator light is bright, plays suggesting effect to operating personnel.
The operation principle of centering control system is as follows:
When after proximity switch and induction installation installation, can set in advance, as when being located at mixing drum 11 front upper with the first proximity switch 1 be located at above bunker mechanism 10 and the 3rd proximity switch 3 conducting, first relay 5 and the 3rd relay 7 conducting, now, the control circuit of trucd mixer starts power supply, and the latch on jockey 13 can insert jack smoothly.When the second proximity switch 2 being located at mixing drum 11 lower front and be located at below bunker mechanism 10 and the 4th proximity switch 4 conducting, second relay 6 and the 4th relay 8 conducting, now, the control circuit of trucd mixer starts power supply, and the latch on jockey 13 can insert jack smoothly.After setting, only have after correlated condition meets, latch just accurately can enter jack, and when effectively preventing latch and jack misalignment, latch stretches out under having the effect of oil cylinder or cylinder, thus damages associated mechanisms.
The centering control system of said structure, operation principle is as follows:
When mixing drum 11 charging, need make bin gate upward and be in open mode, handle the operating grip being positioned at concrete mixing and transporting car side, rotate mixing drum 11, when mixing drum 11 rotates to precalculated position (respective markers can be made on mixing drum), unclamp operation handle, mixing drum 11 stops operating, precalculated position and the mark be arranged on empennage align, now, first sensing chip is positioned near the first proximity switch 1 or the 3rd inductive switch 3, second sensing chip is positioned near the second proximity switch 2 or the 4th proximity switch 4, corresponding relay conducting, the latch of jockey can be extracted from jack.In like manner, during discharging, or in transportation, all need mixing drum 11 and bunker mechanism 10 to align, latch can be extracted or insert.
The centering control system of said structure and concrete mixing and transporting car, tool has the following advantages:
First, the damage of associated mechanisms on trucd mixer is effectively prevented.The centering control system of said structure and concrete mixing and transporting car, only have when mixing drum 11 and bunker mechanism 10 are completely to timing, corresponding relay just can close, the propulsion plant of latch, namely oil cylinder or cylinder etc. just can promote latch in jack, effectively prevent the damage of bunker mechanism.
Secondly, solve that concrete mixing and transporting car useful load is few, center of gravity is high, easy leakages material and moisture evaporates the problems such as fast.The concrete mixing and transporting car of said structure, comprise the bunker mechanism 10 that can be tightly connected with mixing drum 11, when mixing drum 11 is set, the inclination angle of mixing drum 11 can arrange less, in haul process, also can be connected and sealed to mixing drum 11, therefore, efficiently solve that trucd mixer useful load is few, center of gravity is high, easy leakage material and the problem such as moisture evaporation is fast.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
