Abstract
The utility model discloses a safe control system for a power takeoff of a self-dumping truck. The safe control system comprises a pneumatic control valve and a duplex rocker control switch, wherein the pneumatic control valve is connected with the duplex rocker control switch through an external wire; the other end of the duplex rocker control switch is connected with a central control unit and a 30 normally-open fire wire of a self-dumping truck chassis; the pneumatic control valve comprises a pneumatic control valve body, a microswitch, a gear-breaking valve core, a descending chamber and an operation handle; the operation handle is arranged at the upper end of the pneumatic control valve body; the lower end of the operation handle is in threaded connection with a cam; the descending chamber is arranged below the cam; a through hole is formed between a chamber body where the gear-breaking valve core is positioned and the descending chamber; and the microswitch is arranged at the top of the pneumatic control valve body and corresponds to the gear-breaking valve core. The problem that accidents are easily caused due to the fact that the power takeoff of the self-dumping truck is out of control is effectively solved.
Description
Technical field
The utility model belongs to vehicle safety control system, is specifically related to a kind of dumping car power takeoff safety control system.
Background technology
At present; Two types of domestic dumping car chassis great majority all are that the power takeoff on-off controlling system has been installed on the chassis, and according to operating instruction, power take-off valve should be closed when lifting/step-down operation finishes; If chaufeur is forgotten when driving or former thereby power take-off valve is not thrown off for " saving trouble " etc.; Automobile is under the situation of running at high speed, and oil pump causes compartment " automatically " lifting with the hydraulic oil pressure feed liquor cylinder pressure of certain pressure, and there is very big potential safety hazard in it.Dumping car compartment in the process of moving is prone to " automatically " lifting, and accidents caused easily, social influence is abominable, and more many families have brought misfortune.
Summary of the invention
In order to overcome the problems referred to above that the prior art field exists, the purpose of the utility model is, a kind of dumping car power takeoff safety control system is provided, and it is out of control to solve the dumping car power take-off valve, easily accidents caused problem.
The dumping car power takeoff safety control system that the utility model provides; It comprises Pneumatic valve, duplex seesaw master cock; Said Pneumatic valve is connected the Central Processing Unit (CPU) on the duplex seesaw master cock other end and dumping car chassis through external cord with duplex seesaw master cock.
Said Pneumatic valve comprises gas control valve body, micro-switch, disconnected retaining spool, decline chamber, operating handle; Operating handle is arranged on gas control valve body upper end; Its lower end is threaded with cam, and the decline chamber is arranged on below the cam, is provided with through hole between the cavity at disconnected retaining spool place and decline chamber; Micro-switch is arranged on gas control valve body top, and is corresponding with disconnected retaining spool; Said decline chamber also comprises decline chamber air extractor duct, decline chamber piston, and decline chamber air extractor duct is arranged on the bottom of gas control valve body; It also comprises rubber gasket, and its lower end is provided with support spring, is arranged on gas control valve body bottom, and is corresponding with the decline chamber.
The dumping car power takeoff safety control system that the utility model provides; Its beneficial effect is; This control system utilization decline gas circuit automatic guidance power takeoff breaks off and overcurrent control duplex rocker switch automatically resets and locking; Actv. has solved the power take-off valve that compartment " automatically " lifting and artificial origin cause does not throw off, and guarantees the safety of driving, the possibility that the reduction accident takes place.

The specific embodiment
With reference to the accompanying drawings, in conjunction with embodiment, the dumping car power takeoff safety control system to the utility model provides carries out detailed explanation.
Embodiment
With reference to Fig. 1-Fig. 3; The dumping car power takeoff safety control system of present embodiment; It comprises Pneumatic valve 14, duplex seesaw master cock 10; Said Pneumatic valve 14 is connected with duplex seesaw master cock 10 through external cord 2, and duplex seesaw master cock 10 other ends are connected with Central Processing Unit (CPU) 11, the 30 normal open live wires 12 on dumping car chassis; Said Pneumatic valve comprises gas control valve body 8, micro-switch 4, disconnected retaining spool 1, decline chamber, operating handle 5; Operating handle 5 is arranged on gas control valve body 8 upper ends; Its lower end is threaded with cam 3, and the decline chamber is arranged on below the cam 3, is provided with through hole 13 between the cavity at disconnected retaining spool 1 place and decline chamber; Micro-switch 4 is arranged on gas control valve body 8 tops, and is corresponding with disconnected retaining spool 1; Said decline chamber also comprises decline chamber air extractor duct 9, decline chamber piston 6, and decline chamber air extractor duct 9 is arranged on the bottom of gas control valve body 8; It also comprises rubber gasket 7, and its lower end is provided with support spring, is arranged on gas control valve body 8 bottoms, and is corresponding with the decline chamber.
Dumping car rotates through operating handle 5 when descending, and drives the cam 3 that links into an integrated entity with it and rotates; Depress decline chamber piston 6; Decline chamber piston 6 presses down rubber gasket 7 and pushes open, and the gas that gas control valve body 8 lower ends are inserted will get into the decline chamber, and gets into the decline chamber of dumping car lifting valve through decline chamber air extractor duct 9; The switching-over of control lifting valve, body of tipper carriage descends; The pressed gas that descends simultaneously in the chamber gets into the vestibule at disconnected retaining spool 1 place through through hole 13, and it is up to promote disconnected retaining spool 1, and disconnected retaining spool 1 is connected micro-switch 4 contact disks, forms turning circuits through external cord 2.
