Abstract
The utility model provides a warning device for lifting a dumper truck carriage. A negative electrode of a power supply is connected with the ground. A positive electrode is connected with an ignition switch in series and is connected with one end of the switch contact of a control valve. The other end of the switch contact of the control valve is connected with a normally closed switch and an electromagnetic valve coil in series and is connected with the ground. Meanwhile, the other end of the switch contact of the control valve is respectively connected with one end of a buzzer and one end of a flasher. The other end of the buzzer is connected with the ground, and the other two ends of the flasher are respectively connected with an indicating lamp in series and are connected with the ground. Because the control valve is installed at the lower part of the existing dumper truck carriage, an electromagnetic valve is adopted to brake the dumper truck, the buzzer and the indicating lamp are adopted to carry out warning and all devices are connected with each other through circuits, a driver can be warned to avoid the occurrence of accidents. The utility model has the advantages of reasonable design, safety, reliability and simple maintenance and can warn the driver about an abnormal operating state of the dump truck carriage in time.
Description
Technical field
The utility model relates to body dump lifting caution technical field.
Background technology
Dumping truck, particularly heavy dump truck are more extensive in industrial application.But, in the middle of reality is used, the situation of loading space lifting device Control Failure or chaufeur maloperation appears in dumping truck sometimes, cause automobile automatic lifting of loading space when cruising, perhaps the loading space original position automobile that do not fall back in unloading back just is in motoring condition, the therefore generation of initiation grave accident easily.At present, on the existing dumping truck loading space lifting alarming device is not set all, whether its loading space on can't the alerting drivers dumping truck is in normal condition, and story is so hidden danger is bigger.
Summary of the invention
The utility model provides a kind of body dump lifting alarming device, and whether the loading space that it can solve that prior art exists on can't the alerting drivers dumping truck is in normal condition, and accidents caused problem easily.
The purpose of this utility model is achieved through the following technical solutions: body dump lifting alarming device, join ground connection behind control cock switch contact other end series connection normally closed switch, the electromagnetic valve coil behind power cathode ground connection, the anodal series connection ignition lock with control cock switch contact one end; Simultaneously the control cock switch contact other end joins with buzzer phone one end and Der Blink und Abblendschalter one end respectively, buzzer phone other end ground connection, the other two ends of the Der Blink und Abblendschalter ground connection behind the indicator lamp of connecting separately respectively.
The beneficial effect that the utility model can produce: because of loading space bottom installation and control valve at existing dumping truck, and employing electromagnetic valve braking vehicle, and adopt buzzer phone, indicator lamp caution, and each device is connected by circuit, the generation of accident avoided with this alerting drivers.It is reasonable in design, safe and reliable, maintenance is simple, and it can in time warn the abnormal operating state of dumping truck loading space.
Description of drawings
Accompanying drawing is schematic circuit diagram of the present utility model.
The specific embodiment
Body dump lifting alarming device of the present utility model, power supply 9 negative earths, anodal series connection ignition lock 8 backs join ground connection behind control cock 7 switch contact other ends series connection normally closed switch 10, electromagnetic valve 11 coils with control cock 7 switch contacts one end; Simultaneously the control cock 7 switch contact other ends join with buzzer phone 5 one ends and Der Blink und Abblendschalter 3 one ends respectively, buzzer phone 5 other end ground connection, Der Blink und Abblendschalter 3 other two ends indicator lamp 2,4 ground connection afterwards of connecting separately respectively.
During making, various components and parts are assembled by above-mentioned requirements, and control cock 7 is installed in the bottom of loading space 6, electromagnetic valve 11 is installed on the automobile brake, again buzzer phone 5, indicator lamp 2,4 are installed in that vehicle drive is indoor to get final product.During use, when automobile normal running, control cock 7 not conductings of switch contact, each components and parts is not all worked.When loading space 6 liftings, ignition lock 8 closures, control cock 7 switch contact conductings, electromagnetic valve 11 work are with automobile brake, and simultaneously, buzzer phone 5 and indicator lamp 2,4 are all worked, and alerting drivers is noted.This moment, automobile moved as if palpus, then pressed normally closed switch 10, and electromagnetic valve 11 is a brake off.After the normal falling of loading space put in place, control cock 7 switch contacts disconnected, and buzzer phone 5 and indicator lamp 2,4 all quit work.The normal operation of automobile gets final product.The technical division that the utility model is not described in detail is divided into known technology.
