Abstract
A high-voltage preventing alarm device for a crane comprises a high-voltage inductor, a circuit board and an alarm lamp. The alarm device is characterized in that the high-voltage inductor (2) is mounted at the front top end of a lifting arm (1) of the crane, and the circuit board (4) is arranged in an operation platform (3) in an operation room of the crane. The alarm device overcomes the shortcomings of an existing high-voltage preventing alarm device for a crane, can stimulate visual sense and auditory sense of operators by the aid of the alarm lamp and squealing alarm sound, and has the advantages of remarkable alarm effect, simplicity and convenience in production process and the like.
Description
Technical field
The utility model relates to the weight-lifting equipment field, a kind of more precisely warning device that utilizes sensor to prevent to touch in the crane construction high tension cord.
Background technology
The employed crane manoevreability in present various camp site is stronger, the uncertainty of job location, and near the probability that crane is constructed electric power circuit and equipment is more; Therefore suspension arm of crane touching electric power circuit takes place and cause accidents such as electric power circuit tripping operation, broken string, person electric shock; Because such accident often takes place not have the alarming in short range of electric power device on the crane again suddenly, crane operation personnel generally are difficult to discover; In case take place, cause incalculable damage for electric power enterprise and unit in charge of construction.Though the safety instruction of existing crane and warning device occur at present; But extensively adopt LED light and chimes of doom to point out, well-known, the engineering time all by day; The brightness of LED light can't cause crane operation personnel's attention; Add that the camp site noise is all bigger, often covered chimes of doom, the out of reach purpose of warning.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides that a kind of production technology is easy, the anti-alarm for high voltage device of warning obvious results crane.
The purpose of the utility model adopts following technical measures to realize: a kind of crane is prevented the alarm for high voltage device; Form by high voltage induction device, circuit card, warning lamp; It is characterized in that: on the preceding top of suspension arm of crane the high voltage induction device is housed, in crane operation in-house operation platform, circuit card is arranged, be equipped with on the circuit card: amplifying circuit, power circuit, driving circuit; The high-decibel voice frequency circuit is equipped with warning lamp and loud speaker on the operator's station.
The remarkable result of the utility model: owing to adopt warning lamp and high-decibel chimes of doom, can produce operating personal look, the stimulation of the sense of hearing, the warning effect is remarkable, production technology is easy.
Description of drawings
Accompanying drawing 1 is the constructional drawing of the utility model arm;
Accompanying drawing 2 is the constructional drawing of the utility model operator's station;
Accompanying drawing 3 is the electric functional block diagram of the utility model.
Below in conjunction with accompanying drawing the utility model is done further to set forth.
The specific embodiment
Referring to figure, on suspension arm of crane 1 preceding top high voltage induction device 2 is housed, in crane operation in-house operation platform 3, circuit card 4 is arranged, be equipped with on the circuit card: amplifying circuit, power circuit, driving circuit, the high-decibel voice frequency circuit is equipped with warning lamp 5 and loud speaker 6 on the operator's station.
Claims (3)
1. the anti-alarm for high voltage device of crane is made up of high voltage induction device, circuit card, warning lamp, it is characterized in that: on the preceding top of suspension arm of crane (1) high voltage induction device (2) is housed, circuit card (4) is arranged in crane operation in-house operation platform (3).
2. by the anti-alarm for high voltage device of the described crane of claim 1, it is characterized in that: circuit card is equipped with on (4): amplifying circuit, power circuit, driving circuit, high-decibel voice frequency circuit.
3. by the anti-alarm for high voltage device of the described crane of claim 1, it is characterized in that: warning lamp (5) and loud speaker (6) are housed on the operator's station (3).
