Description

Crane alarming in short range of electric power safety device
Technical field
The utility model relates to engineering construction protection field, especially a kind of crane alarming in short range of electric power safety device.
Background technology
The employed crane manoevreability in present various camp site is stronger, when crane is constructed near electric power circuit and equipment, the arm touching easily takes place or close on electric power circuit and cause accidents such as electric power circuit tripping operation, broken string, person electric shock, because such accident often takes place suddenly, there is not nearly electric alarm device on the crane again, crane operation personnel generally are difficult to discover, and cause incalculable damage for electric power enterprise and unit in charge of construction.Outer in recent years broken accident frequently takes place, wherein the outer broken very big ratio that accounts for of crane short initiation.
Summary of the invention
Problem to be solved in the utility model is, avoids the touching of gib arm arm or closes on electric power circuit and cause the generation of accidents such as electric power circuit tripping operation, broken string, person electric shock.
The utility model uses the high voltage induction device, makes gib arm when closing on electric power circuit, can feel the existence of the electric field of electric power circuit, thus the alerting signal of sending, and concrete technical scheme is as follows:
A kind of crane alarming in short range of electric power safety device comprises power supply, high voltage induction device, controller and warning device, and power supply links to each other with warning device with controller; The output of high voltage induction device connects the input end of controller, and the mouth of controller connects warning device; Described high voltage induction device is located at the gib arm front end.
Described warning device comprises phonetic alarm device, LED display and stand by lamp.Described phonetic alarm device and LED display are located in the control cabin, and stand by lamp is located at the car body outside.
As a kind of improvement, the output of high voltage induction device is by the input end of wire connection controller.
Improve as another kind, the mouth of described high voltage induction device is provided with wireless signal transmitting device, and the input end of controller is provided with the wireless signal receiving device, and the output of high voltage induction device connects the input end of controller by wireless signal.
When arm closes on electric power circuit, the high voltage induction device will be sensed the existence of electric field, and triggers controller, signals to phonetic alarm device and LED display in the control cabin, inform the crane operation personnel: arm should be taked the measure of dodging immediately near electric power circuit.Meanwhile, the stand by lamp on the vehicle body also is triggered, and by the flicker of stand by lamp, personnel give the alarm to site operation, allows its attention dodge, and to avoid personal injury accident.
Compared with prior art, the utlity model has failure-free closing electricity prevention warning function, the time close on or touch electric power circuit in construction but actv. prevents crane, and accidents such as the electric power circuit that takes place tripping operation, broken string, personal electric shock.This device is applicable to relevant industries such as building, traffic, electric power, can effectively reduce the electric shock accidents incidence of unit in charge of construction, guarantees the safety of the person and equipment.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
A kind of crane alarming in short range of electric power safety device comprises power supply, high voltage induction device 1, controller 4 and warning device, and power supply links to each other with warning device with controller; The mouth of high voltage induction device 1 connects the input end of controller 4, and the mouth of controller 4 connects warning device; Described high voltage induction device 1 is located at the gib arm front end.Described warning device comprises phonetic alarm device 3, LED display and stand by lamp 2.Phonetic alarm device 3 and LED display are located in the control cabin, and stand by lamp 2 is located at the car body outside.
Power supply is got crane DC12V power supply, and the high voltage induction device adopts existing matured product, and optional model is many, exceeds explanation at this.Under the mode of operation, the K that closes a switch in case the signal of high voltage induction device is arranged, then triggers phonetic alarm device, LED display and stand by lamp.
Example 1, reference view 2, in this example, the mouth of high voltage induction device 1 connects the input end of controller 4 by lead 5.
Example 2, reference view 3, in this example, the mouth of high voltage induction device 1 is provided with wireless signal transmitting device, and the input end of controller 4 is provided with the wireless signal receiving device, and the output of high voltage induction device 1 connects the input end of controller 4 by wireless signal.Wireless signal transmitting device in this example and wireless signal receiving device are matured products of the prior art, and optional kind is more, does not make too many restrictions at this.
