Abstract
The utility model discloses a dumper power takeoff module safety control device. The dumper power takeoff module safety control device comprises a central control unit, a power takeoff and a power takeoff solenoid valve, and further comprises a self-reset power takeoff rocker switch, an electronic module and a hand valve micro switch. The electronic module outputs an on/ off signal and the power takeoff solenoid valve is controlled. An input end of the electronic module is connected with the self-reset power takeoff micro switch. An output end of the electronic module is connected with an input end of the central control unit. An output end of the central control unit is connected with the power takeoff solenoid valve. The hand valve micro switch is connected with the electronic module. The hand valve micro switch senses descending of a wagon body and automatically switches on, and the electronic module outputs the off signal. According to the dumper power takeoff module safety control device, the self-reset power takeoff micro switch is used and an initial state of the micro switch is kept. Due to the fact that the power takeoff micro switch is triggered in an instant, factitious false operation is effectively avoided.
Description
Technical field
The utility model belongs to the shipment vehicle unloading control device with self-unloading device, is specifically related to a kind of dumper power takeoff module safety control.
Background technology
Automobile is in the situation that run at high speed, if power takeoff is not thrown off, oil pump will cause carriage lifting with the hydraulic oil pressure inlet hydraulic cylinder of certain pressure, and compartment " automatically " lifting meeting causes safety misadventure, cause most evil bad social influence, more can bring misfortune for many families; At present, two domestic class self-dumping undercarriage for automobile great majority all are that the power takeoff on-off controlling system has been installed on the chassis, if chaufeur is thrown off power take-off valve danger that will potential generation this " automatically " lifting when driving.
Summary of the invention
The defects that exists in order to overcome the prior art field, the purpose of this utility model is, a kind of dumper power takeoff module safety control is provided, and prevents that compartment " automatically " lifting from causing safety misadventure, guarantees traffic safety.
The dumper power takeoff module safety control that the utility model provides, comprise Central Processing Unit (CPU), power takeoff and power takeoff electromagnetic valve, it also comprises Self-resetting power takeoff rocker switch, electronic module and hand valve micro-switch, electronic module output is logical, break signal control power takeoff electromagnetic valve, the input end of electronic module connects Self-resetting power takeoff rocker switch, the mouth of electronic module connects the input end of Central Processing Unit (CPU), the mouth of Central Processing Unit (CPU) connects the power takeoff electromagnetic valve, described hand valve micro-switch connecting electronic module, hand valve micro-switch induction compartment descends and automatically connects, electronic module output cut-off signal, described Central Processing Unit (CPU) is installed on the car chassis.
The dumper power takeoff module safety control that the utility model provides, its beneficial effect are, use Self-resetting power takeoff rocker switch, keep the virgin state of rocker switch, and the power takeoff rocker switch is instantaneous trigger, has effectively avoided artificial misoperation; Control to the power takeoff electromagnetic valve realizes by electronic module, guarantees traffic safety.
Description of drawings
Fig. 1 is the electrical schematic of an embodiment of the utility model.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the dumper power takeoff module safety control that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1, the dumper power takeoff module safety control of the present embodiment comprises Central Processing Unit (CPU) CBCU, power takeoff and power takeoff electromagnetic valve Y1, it also comprises Self-resetting power takeoff rocker switch SA1, electronic module and hand valve micro-switch SA2, electronic module output is logical, break signal control power takeoff electromagnetic valve Y1, the input end of electronic module connects Self-resetting power takeoff rocker switch SA1, the mouth of electronic module connects the input end of Central Processing Unit (CPU) CBCU, the mouth of Central Processing Unit (CPU) CBCU connects power takeoff electromagnetic valve Y1, described hand valve micro-switch SA2 connecting electronic module, hand valve micro-switch SA2 induction compartment descends and automatically connects, electronic module output cut-off signal, described Central Processing Unit (CPU) CBCU is installed on the car chassis.
The control principle of dumper power takeoff module safety control is as follows: before the Tipper Lifting, press first Self-resetting power takeoff rocker switch SA1, electronic module output connection signal, to one of the Central Processing Unit (CPU) CBCU input end on the car chassis " " signal, 24V positive potential of CBCU output is to power takeoff electromagnetic valve Y1, power takeoff electromagnetic valve Y1 work, the power takeoff combination, the operation hand control valve (HCV) makes carriage lifting; When body of tipper carriage descended, the pressed gas in the hand control valve (HCV) decline chamber was connected micro-switch SA2, and electronic module output cut-off signal makes the Central Processing Unit (CPU) CBCU input end on the car chassis unsettled, power takeoff electromagnetic valve Y1 dead electricity, and power takeoff is thrown off.If after connecting power takeoff electromagnetic valve Y1, do not have unloading to need again to continue driving, only need to click again Self-resetting power takeoff rocker switch SA1, electronic module will be exported cut-off signal, makes power takeoff electromagnetic valve Y1 dead electricity, and power takeoff is thrown off, and guarantees the driving peace
Dumper power takeoff module safety control uses Self-resetting power takeoff rocker switch, keeps the virgin state of rocker switch, and the power takeoff rocker switch is instantaneous trigger, has effectively avoided artificial misoperation.
