Description
Technical field
The utility model relates to the crane equipment technical field.
Background technology
Present most of crane has that suspension hook is spacing, weight overload auto-stop, the uneven warning function of car load, and these functions are finished by micro controller system, but for station people and bar head range finding or blank under the arm.In high-altitude application in the past, run into the objects such as body of the tower, cross-arm and wire in order to prevent crane arm, need at least 3 people observe from different perspectives commander, crane operation person should operate crane arm and note again all angles commanding, particularly during Proximity operation point, the operator is nervous especially, can only bit by bit operate, speed is slow especially, so not only impact lifting operating speed, and the long-time operation operating personal can because of the dispersion of fatigue energy, bring safety hazard.Such situation is also often arranged when lifting operation, for a long time lifting operation, field man is generally paid much attention to lifting object, does not often note the erect-position of oneself, sometimes may stand in unconsciously the below of large arm, has so just brought potential safety hazard.Simultaneously, mostly the lifting working environment is that in the open air it is large that car rings noise, and car loudspeaker voice prompt is dull, and the people outside operating personal is propagandaed directed to communicate in operator's compartment does not hear that again the necessary often turnover of operator operator's compartment brings inconvenience to work like this.
The utility model content
The technical problems to be solved in the utility model provides a kind of crane operation safety early warning device, has simple in structurely, and good to arm servant, the expressivity of thing safe police, operation accuracy and safety are good, saving of work and time, the advantage such as can increase work efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: comprise the micro controller system with load module and output module, load module is connected with human body sensor under bar head distance measuring sensor and the crane arm in addition, output module is connected with voice module, and voice module is connected with loud speaker.
The utility model further improves and is: load module also is connected with lifting operation voice prompt button;
The preferred ultrasonic transduter of bar head distance measuring sensor; Output module also is connected with flash warning lamp.
The beneficial effect that adopts technique scheme to produce is: have simple in structurely, good to arm servant, the expressivity of thing safe police, operation accuracy and safety are good, saving of work and time, good reliability, the advantage such as can increase work efficiency.Load module is connected with human body sensor under bar head distance measuring sensor and the crane arm, and output module is connected with voice module, and voice module is connected with loud speaker.Bar head distance measuring sensor can be surveyed the object distance such as body of the tower, cross-arm and wire of crane arm sense of motion, and carry out voice suggestion by voice module, to prevent the generation of collision accident, change automatic detection into by before artificial supervision, the lifting commanding is kept to 1 people by at least three original people, reduced cost of labor, improved work efficiency, human body sensor can be to whether the someone monitors under the crane arm under the crane arm, and carry out voice suggestion by voice module, guarantee site operation personnel's personal safety; Load module also is connected with lifting operation voice prompt button, in the time will carrying out lifting operation, presses this action button, and voice module namely carries out corresponding voice suggestion, reminds the related personnel to take care; Output module also is connected with flash warning lamp, and when night, sight line was bad, if under the crane arm people is arranged, voice suggestion and red flash warning lamp will start simultaneously, and alert is noted speeding away, and eliminates safe hidden trouble.The utility model plays the safety control effect to crane operation, and can reduce the signalman personnel, increases work efficiency.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Description of drawings
Fig. 1 is frame principle figure of the present utility model.
The specific embodiment
By embodiment shown in Figure 1 as can be known, it comprises the micro controller system with load module and output module, load module is connected with human body sensor under bar head distance measuring sensor and the crane arm in addition, output module is connected with voice module, and voice module is connected with outdoor loudspeaker and indoor monitoring loudspeaker.Utilize the original load module of micro controller system and output module interface, the sensor is connected with voice module, improved the degree of utilization of equipment, reduced cost of installation, human body sensor adopts infradred sensor under the crane arm, be installed on crane the place ahead crane arm lower position, in order to increase its directivity, pilot hole is installed in inductive probe the place ahead, the main frame voice module adopts FY-07 chip, multiwave voice dialogue can be set, can in time change the voice broadcast content by the computer conv, in real work, can both adjust timely the voice broadcast content in the different job specification of different working environments.
Load module also is connected with lifting operation voice prompt button.Press this button and can carry out scene beginning operation notice voice broadcast.
Bar head distance measuring sensor adopts ultrasonic transduter.Be installed on nose, ultrasonic transduter has reliable operation, the characteristics that cost is low.
Output module also is connected with flash warning lamp.Night work there is good safe warning function.
Principle of work of the present utility model is as follows: when super sonic bar head distance measuring sensor detects nose obstacle is arranged, can produce on-off signal, load module detects this on-off signal and processes through CPU, trigger the corresponding voice content of voice module by output module, can carry out the audio alert prompting; When the infrared ray human body sensor is sensed the infrared ray that human body sends, can produce on-off signal, load module detects this on-off signal and processes through CPU, trigger the corresponding voice content of voice module by output module, can carry out the audio alert prompting, also the trigger flashing Warning light carries out flashing light alarm simultaneously; In the time will carrying out lifting operation, press lifting operation voice prompt button, can produce on-off signal, load module detects this on-off signal and processes through CPU, trigger the corresponding voice content of voice module by output module, voice module namely carries out corresponding voice suggestion, takes care to remind the related personnel.But the safety of the utility model Effective Raise crane operation.
