When vehicle is worked under driving mode, the two poles of the earth speed-regulating mode work of driving engine to match with it, driving engine can be responded apace according to the instruction of line conditions and chaufeur, sufficient power is provided, and the consumption of having saved fuel oil, make concreting machinery under driving cycle, be in best mode of operation; When vehicle was worked under the pumping pattern, the full distance speed regulating pattern work of driving engine to match with it had improved the speed of response of driving engine and the stability of engine speed, has prolonged the service life of driving engine, has saved fuel simultaneously.
Please refer to Fig. 2, Fig. 2 is the schematic diagram of concreting machinery mode of operation control system shown in Figure 1.
As shown in Figure 2, particularly, the vehicle mode control setup comprise armored pump send pattern control change-over switch 1, on adorn driving mode control change-over switch 2, driving engine full distance speed regulating transfer relay 4 and driving engine the two poles of the earth speed governing transfer relay 3; When last dress driving mode is controlled change-over switch 2 closures, described driving engine the two poles of the earth speed governing transfer relay 3 is connected, driving engine is switched to the two poles of the earth speed-regulating mode, when last armored pump send pattern control change-over switch 1 closure, described driving engine full distance speed regulating transfer relay 4 is connected, driving engine is switched to the full distance speed regulating pattern, and the existence of driving engine full distance speed regulating transfer relay 4 and driving engine the two poles of the earth speed governing transfer relay 3 makes that the conversion of engine governed speed pattern can very succinct, realization easily.Certainly, can realize that engine mode follows the device that vehicle mode automaticallyes switch and be not limited to above-described relay, other can realize that engine mode follows the device that vehicle mode automaticallyes switch and all be fine.
Please refer to Fig. 3, Fig. 3 is second kind of the utility model concreting machinery mode of operation control system control process scheme drawing that the specific embodiment provided.
Concreting machinery mode of operation control system provided by the utility model further comprises and is used to detect the detecting device whether concreting machinery is in motoring condition.When concreting machinery was in non-motoring condition, described engine mode shifter switched the pattern of described driving engine according to the action of described vehicle mode shifter; When concreting machinery was in motoring condition, described engine mode shifter kept the original pattern of described driving engine.
In a kind of specific embodiment, concreting machinery mode of operation control system control process provided by the utility model specifically can may further comprise the steps:
Step S1: the switching command that sends vehicle mode.
Chaufeur sends the vehicle mode switching command according to the requirement of work operating mode.In the actual use, the vehicle mode switching command is by the opening and close and send of vehicle ' switch and vehicle pumping switch, and generally being chaufeur switches vehicle ' switch and vehicle pumping switch according to the needs of work operating mode.
Step S2: judge whether concreting machinery is in motoring condition.
After the switching command of vehicle mode sends, be used to detect the state whether concreting machinery is in the detecting device detection vehicle travel switch of motoring condition, when the vehicle ' switch is in closure state, show that vehicle is in motoring condition, turn to step S31; When the vehicle ' switch is in open mode, show that vehicle is in non-motoring condition, turns to step S32.
Step S31: keep vehicle mode constant.
Described vehicle mode shifter is ignored the vehicle mode switching command, keeps vehicle mode constant, and execution in step S41.
Step S41: keep engine mode constant.
Because vehicle mode is constant, therefore, engine mode also remains unchanged, and keeps the pattern of driving engine and the coupling of vehicle mode.
Step S32: carry out the vehicle mode switching command.
When vehicle was not in motoring condition, described vehicle mode shifter carried out the switching of vehicle mode according to the switching command of vehicle mode, and execution in step S42.
Step S42: carry out engine mode and switch.
Carry out the switching of engine mode according to the switching command of vehicle mode, keep the pattern of driving engine and the coupling of vehicle mode.
Therefore, the existence of detecting device has guaranteed that vehicle only just carries out vehicle mode and switch name under the inoperative driving mode, has avoided the operational mode of vehicle under motoring condition to change the danger that brings, and has guaranteed the safety of vehicle operating.Further, realize that the measure of detection vehicle running state is not limited to the state of above-described detection vehicle travel switch, other methods that can realize this function all are fine.
Except above-mentioned concreting machinery mode of operation control system, the utility model also provides a kind of single-shot walking concreting machinery that comprises above-mentioned concreting machinery mode of operation control system, the structure of described other each several parts of single-shot walking concreting machinery please refer to prior art, and this paper repeats no more.
Particularly, above-mentioned single-shot walking concreting machinery can be a concrete pump truck.
More than concreting machinery mode of operation control system provided by the utility model and single-shot walking concreting machinery are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
