Working principle:
Excessive hoisting machinery malformation is the premise for causing hoisting machinery to topple, this instrument passes through laser reflection principle,
Emit laser beam by vertical and horizontal, after reflection point is installed at each position, receives laser position.When laser spot is beyond permission
When range, sound-light alarm is issued, operator is reminded to stop.This system does not take the mode for being automatically stopped hoisting machinery, because hanging
Unexpected arrestment operation will cause equipment and topple when transporting weight.Firstly, opening controller 22, battery 23 starts to provide dynamic
Power, at this moment, starting lifting trolley 7 allows lifting trolley 7 to be moved along slideway 6, is moved to suitable position, starts automatically controlled push away
Bar 8, automatically controlled push rod 8 eject Elastic buckle 9, by the lifting lock of trolley 7 in 6 middle position of slideway, then start the second fixed frame
Horizontal laser light transmitter 11 on 10, laser start to practice shooting, and laser passes through the refraction of reflecting mirror 13, beat in first laser receiver
On 12, starting the vertical laser emitter 15 in third fixed frame 14, laser is beaten on second laser receiver 16, so then
Undeformed for hoisting machinery structure, after the laser that horizontal laser light transmitter 11 emits, laser is not got to by reflecting mirror 13
When in 12 specified range of first laser receiver, situation is fed back to controller 22 by the starting of the first perceptron 17, and controller 22 is controlled
Loudspeaker 20 and warning light 21 processed are alarmed, and equally, vertical laser emitter 15 is beaten less than on second laser receiver 16
Specified range in when, situation will be fed back to controller 22 by the starting of the second perceptron 18, controller 22 control loudspeaker 20 with
And warning light 21 is alarmed, this system can be widely used on the various lifting equipments of various working environments, remind operation in real time
It is safe to guarantee that hoisting machinery uses for personnel equipment's deformation condition, and 12, three reflecting mirrors 13 of first laser receiver are installed in ring
5 upper surface edge of shape support plate；
Embodiment one: German SP Status Pro can be used in horizontal laser light transmitter 11 and vertical laser emitter 15
Original-pack certified products T250, T330 laser emitter；
Embodiment two: ceramic package silicon photocell sense can be used in first laser receiver 12 and second laser receiver 16
Smooth surface 10*10 sensor laser pickoff silicon photoelectric diode 2DU10；
Embodiment three: laser target shooting range is measured by undeformed hoisting machinery structure, carries out unloaded survey first
Fixed, by laser target shooting, laser is beaten at 16 center of first laser receiver 12 and second laser receiver, is then expired
Measurement is carried, hoisting machinery is fully loaded, the limit operation of each amplitude is then carried out, while carrying out real-time laser target shooting, thus
To an effective measurement range, when to hoisting machinery structure measurement, laser is got within the scope of this, then not will call the police；
Example IV: when installation, the angle of reflecting mirror 13 is 45 °, vertical laser emitter 15 and second laser receiver
16 be plumbness；
Embodiment five: such as goliath crane tool can be installed directly in the girder upper surface edge of goliath crane tool
Detection structure, in the driving indoor location alarm structure and control structure of goliath crane tool, so that driver can be timely
It was found that hoisting machinery deforms；
Embodiment six: such as bridge type hoisting machinery can install horizontal laser light hair directly on the girder of bridge type hoisting machinery
Emitter 11, first laser receiver 12, three reflecting mirrors 13, alarm structure and control structures, do not need to install vertical laser
Transmitter 15 and second laser receiver 16,12, three horizontal laser light transmitter 11, first laser receiver reflecting mirrors 13 are installed
In the girder upper surface edge of bridge type hoisting machinery, alarm structure and control structure are mounted in driver's cabin, so that driving
Member can timely have found that hoisting machinery deforms；
Embodiment seven: such as wireless control hoisting machinery can install alarm knot on wireless control hoisting machinery controller
Structure and control structure, so that operator can timely have found that hoisting machinery deforms.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
