2, force the control risky operation, when vehicle running (being run-off the straight) when surpassing the setting perch, the obliquity sensor output signal; Can demonstrate danger signal through the read-out on the singlechip controller; The prompting of voice display alarm is dangerous, and the singlechip controller hazard output signal stops loading space by force and continues lifting work simultaneously; And make under the loading space and roll back perch, avoid loading space to turn on one's side because of inclination and offset.
3, the rationalization of dangerous play control behind singlechip controller, by force with hydraulic cylinder piston is back to perch through Multistage Control by the inclination sensor hazard output signal, realizes forcing controlled hydraulic system to perch.
The vehicle rollover rate that sedimentation causes takes place in the road surface that 4, reduces greatly because of misoperation or tire contact, can realize the generation of prevention and control rollover accident in advance.
5, the anti-inclination autonomous cruise speed system of this automobile hydraulic lifting, have simple in structure, good reliability, comformability is strong, applied range can reduce the generation that vehicle lifting causes the rollover accident greatly.
Description of drawings
Fig. 1 is the structural representation of the anti-inclination autonomous cruise speed system of automobile hydraulic lifting;
Fig. 2 is the principle schematic of the anti-inclination autonomous cruise speed system of automobile hydraulic lifting.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done to describe in further detail.
Like Fig. 1, shown in 2, the anti-inclination autonomous cruise speed system of automobile hydraulic lifting comprises lifting valve, singlechip controller, obliquity sensor, near switch, lifting electromagnetic valve of gas circuit, exit way solenoid valve, exit way solenoid valve and voice display alarm slowly soon.Obliquity sensor is located on vehicle body or the chassis ridgepole, is located on the auxiliary girder of chassis near switch, and is corresponding with the track of loading space in lifting process near the inductive head part of switch.The lifting electromagnetic valve of gas circuit is connected with the lifting gas control port of lifting valve through tracheae, and the way solenoid valve of exitting soon is connected with the fast venting control port of lifting valve through tracheae, and the way solenoid valve of exitting slowly is connected with the control of the venting slowly port of lifting valve through tracheae.The detection signal input singlechip controller of obliquity sensor; The safety signal mouth of singlechip controller is connected with the lifting electromagnetic valve of gas circuit; The danger signal mouth of singlechip controller is connected with fast venting way solenoid valve; Normally closed contact near switch is electrically connected with fast venting way solenoid valve, is electrically connected with the way solenoid valve of exitting slowly near the normal opened contact of switch.
In the present embodiment; Obliquity sensor is two; Obliquity sensor 1 is located at the middle part of chassis ridgepole transom beam, and obliquity sensor 2 is located at the middle part (in the present embodiment, inclination sensor 2 is installed in the position of front side, compartment ceiling apart from top 100～300mm) of ceiling bottom, front side, compartment.Be located at apart from invert center axle 100～500mm behind the compartment (compartment goes downwards to apart between auxiliary girder angle 10 degree～15 degree) near switch, near switch apart from the compartment after the distance of invert center axle can select for use 100mm, 140mm, 180mm, 200mm, 250mm or 300mm all can.Singlechip controller adopts dipmeter TC-XST; This dipmeter had both had judges and confirms to be safety signal or danger signal to the signal of obliquity sensor output; The function that has light-emitting diode display again; Can the bevelled angle be shown, this dipmeter is an existing product, repeats no more at this.Dipmeter and voice display alarm are installed in the operator's compartment; The voice display alarm is connected with dipmeter; In case dipmeter is judged as danger signal, the voice display alarm just sends warning, and the navigating mate in the operator's compartment is played reminding effect.
In the position of automotive operation to unloading, at ground steadily and the no heeling condition of vehicle self, when meeting the steady lifting condition of vehicle; Open the lifting electromagnetic valve, the anti-inclination autonomous cruise speed system energising of this automobile hydraulic lifting just can be monitored inclination of vehicle at any time; Obliquity sensor (obliquity sensor 1 with obliquity sensor 2 in any one) no abnormal information (in singlechip controller, making in the safety critical point range of inclination of vehicle); Hoisting system normally moves, singlechip controller output safety signal, and the lifting electromagnetic valve of gas circuit is in open mode; Oil cylinder piston continues to rise, and is unsnatched until goods.
If the front side of loading space is in the lifting process; Obliquity sensor (obliquity sensor 1 with obliquity sensor 2 in any one) transmission abnormality information (surpassing the safety critical point range that makes in the singlechip controller); Singlechip controller receives the angle of inclination information of obliquity sensor transmission; Singlechip controller implement to be differentiated data, and hoisting system is controlled (lifting, put soon, put slowly), simultaneously with information transfer to light-emitting diode display and voice display alarm.Singlechip controller sends distress signal, and closes the lifting electromagnetic valve of gas circuit immediately, and oil cylinder piston stops up, opens fast venting way solenoid valve simultaneously, and the valve that falls soon on the lifting valve is opened, and oil cylinder piston is descending fast; Between the compartment goes downwards to apart from auxiliary girder angle 10 degree～15 degree; The side contact in compartment is near switch; Near the switch hard closing way solenoid valve of exitting soon, open slow sending down abnormally ascending way solenoid valve simultaneously, the valve that falls slowly on the lifting valve is opened; Oil cylinder piston is descending at a slow speed, makes the compartment slowly be returned to initial position (being on the chassis ridgepole).
The anti-inclination autonomous cruise speed system of this automobile hydraulic lifting can be mainly used in various dumping cars, crane, mix earth pump truck, aerial platform, bridge inspection car, special vehicle, construction machinery and equipment, petroleum machinery, ocean engineering, metallurgy industry, military industry equipment, boats and ships etc.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of present technique scheme, it all should be encompassed in the middle of the claim scope of the present invention.
