Abstract
The utility model discloses a kind of excavator safety device for proventing electrical shock, comprise power supply, high voltage induction device, controller, and alarm lamp, power supply connects and is that controller and alarm lamp are powered; The input of the output connection control device of high voltage induction device, the output of controller connects alarm lamp; Described high voltage induction device is located at the bucket front end of digging machine.The utility model structure is simple, provide a kind of excavator safety device for proventing electrical shock, when forceful electric power cable appears in digging operation safe range, safety device can remind operating personnel that excavator is quit work by automatic alarm, greatly improve the safety of excavator when operation, guarantee the safety of the person and equipment.
Description
Technical field
The utility model relates to engineering construction protection field, especially a kind of digging machine Antistatic alarm.
Background technology
Excavator is a kind of conventional engineering machinery, is widely used in earthwork construction, urban construction, the occasions such as construction of water conservancy works.In recent years, excavator is when urban construction and municipal construction, and the security incident that disconnected underground cable occurs in operation process to get an electric shock or dig often has generation, mainly contains two reasons, and one is that driver is negligent of when constructing observing; Two is that in avenue, underground cable moves towards complicated, cannot be accurately directed; The height of land cable is on the low side, is substantially in the normal range of operation of excavator, brings great difficulty like this to the strick precaution of accident.
Utility model content
Easily there is the security incident of getting an electric shock or digging disconnected underground cable when being the work of existing excavator in the technical problems to be solved in the utility model, produces huge hidden danger to the personal safety of operator.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of excavator safety device for proventing electrical shock, comprises power supply, high voltage induction device, controller, and alarm lamp, and power supply connects and is that controller and alarm lamp are powered; The input of the output connection control device of high voltage induction device, the output of controller connects alarm lamp; Described high voltage induction device is located at the bucket front end of digging machine.
When bucket closes on power cable, high voltage induction device will sense the existence of electric field, and trigger controller, alarm lamp on digging machine arm is also triggered, and by the flicker of alarm lamp, gives the alarm to site operation personnel and digging machine operator, allow its attention dodge, to avoid personal injury accident.
For strengthening alarming effect further, be also provided with phonetic alarm device, described phonetic alarm device is also by Power supply, and the output of controller connects the input of phonetic alarm device, and described phonetic alarm device comprises audio alert player and light-emitting diode display.When after high voltage induction device trigger controller, controller signals to audio alert player in control room and LED display, informs that digging machine operating personnel bucket is close to power cable, should take measures to keep clear immediately from sound and image two aspect.
For ensureing the remarkable of prompting effect, the outer digging machine arm stage casing of car is located at by alarm lamp.The outer digging machine arm stage casing of car is located at by alarm lamp, can and locate in digging machine operating personnel sight line, and not only the outside employee of excavator is visual, and built-in function person is also convenient to observe.
As a kind of improvement project of the present utility model, the output of described high voltage induction device is connected with wireless signal transmitting device, the input of controller be connected with above-mentioned wireless signal transmitting device with the use of wireless signal receiver.Adopt wireless signaling mechanisms transmission of information, decrease line and connect, avoid the failure problems of the aging generation of line.
The utility model has the advantages that: structure is simple, provide a kind of excavator safety device for proventing electrical shock, when forceful electric power cable appears in digging operation safe range, safety device can remind operating personnel that excavator is quit work by automatic alarm, greatly improve the safety of excavator when operation, guarantee the safety of the person and equipment.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation; Fig. 2 is circuit diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1-2, the utility model comprises power supply, high voltage induction device 1, controller 5, alarm lamp 2 and phonetic alarm device, and power supply is connected with alarm lamp 2 and phonetic alarm device with controller 5; The input of the output connection control device 5 of high voltage induction device 1, the output of controller 5 connects alarm lamp 2 and phonetic alarm device; Described high voltage induction device 1 is located at digging machine bucket front end; Described alarm lamp 2 is arranged at digging machine arm operating personnel sight line and can and locates; Described warning device comprises audio alert player 4, LED display 3. audio alert player 4 and LED display 3 and is located in control room.
Power supply gets crane DC12V power supply, and high voltage induction device adopts existing matured product, and optional model is many, exceeds explanation at this.Under duty, close a switch K, once there be the signal of high voltage induction device 1, then and triggering voice warning player 4, LED display 3 and alarm lamp 2.
In this example, the output of high voltage induction device 1 is provided with wireless signal transmitting device, and the input of controller 5 is provided with wireless signal receiver, and the output of high voltage induction device 1 is by the input of wireless signal connection control device 5.Wireless signal transmitting device in this example and wireless signal receiver are matured products of the prior art, and optional kind is more, does not make too many restrictions at this.
