The hook inclination alarm device can accurately reflect the inclination condition of the hook in real time when a travelling crane lifts an object, thereby avoiding the violation phenomenon of skew pulling and suspending, meanwhile timely instructing the travelling crane driver to control and adjust the shaking of the hook so as to ensure the production safety.
Description
Technical field
The utility model relates to a kind of warning device, particularly a kind of suspension hook inclination alarming device that is used to prevent the suspension hook run-off the straight of elevator machinery.
Background technology
All need use elevator machinery in the every profession and trade at home and abroad, with the handling various items.When the lifting object,, perhaps lift by crane according to the visual judgement of oneself by the driving chaufeur generally according to commander's lifting.Lift by crane object howsoever, because the actual tilt of suspension hook is lacked with reference to foundation, can only be according to the experience that accumulates separately, so can not guarantee the vertical lifting of object.
In addition, often since when long work cause asthenopia easily, add that fog in the operating environment, dirt ash are excessive; Factor such as personal experience, current mood all can cause the phenomenon of " askew skewing hung "." inaccurate askew skewing hung " is exactly that ten of crane does not hang one of ban." in case askew skewing hung ", the lifting object is in the moment of built on stilts, because there is certain angle in steel rope with ground, the pulling force that steel rope bears object weight can produce horizontal component.Generation is rocked by the effect of transverse force when causing weight to be sling, rock size and change with " askew skewing hung " degree.Like this, if the lifting object produces very big rocking, light damage equipment then is heavy then will cause great personal injury accident.
Summary of the invention
For addressing the above problem, the utility model provides a kind of suspension hook inclination alarming device, and whether suspension hook has tilted to have a clear and definite caution during to lifting, thereby the handling object that rocks is adjusted, and avoids taking place unnecessary safety misadventure.
For achieving the above object, suspension hook inclination alarming device of the present utility model, receive warning device by light launcher and light and constitute, described light launcher comprises a vertical light-emitting source and an adjustable support, and described vertical light-emitting source is fixed on an end of described adjustable support; Described light receives warning device and comprises and receive warning box and light control alarm unit, and described light control alarm unit is installed in and receives in the warning box, and the top of described reception warning box is provided with a receiver hole, described receiver hole be positioned at described vertical light-emitting source under; Described light control alarm unit comprises a light receiver, described light receiver be positioned at described receiver hole under.
The below of described reception warning box is provided with a plurality of magnet, and described magnet passes through bolted connection with the bottom that receives warning box.On the bolt of described connection reception warning box and magnet spring is arranged.
Described light receiver is a photodiode.
Suspension hook inclination alarming device of the present utility model, the inclination situation of suspension hook can reflect accurately and real-time during to driving lifting object, thereby avoids the violation phenomenon of " askew skewing hung ", in time instructs the driving chaufeur that rocking of suspension hook handled adjustment simultaneously.Thereby guaranteed the safety of producing.
Description of drawings
Fig. 1 is the scheme drawing of suspension hook inclination alarming device of the present utility model;
Fig. 2 is that suspension hook inclination alarming device of the present utility model is installed in the scheme drawing on the suspension hook;
Fig. 3 is the circuit diagram of the light control alarm unit of suspension hook inclination alarming device of the present utility model.
The specific embodiment
Fig. 1 is the scheme drawing of suspension hook inclination alarming device of the present utility model, as shown in the figure, suspension hook inclination alarming device of the present utility model receives warning device 2 by light launcher 1 and light and constitutes, described light launcher 1 comprises a vertical light-emitting source 11 and adjustable support 12, and described vertical light-emitting source 11 is fixed on an end of described adjustable support 12; Described light receives warning device 2 and comprises reception warning box 21 and light control alarm unit 22, described light control alarm unit 22 is installed in and receives in the warning box 21, the top of described reception warning box 21 is provided with a receiver hole 210, described receiver hole 210 be positioned at described vertical light-emitting source 11 under; Described light control alarm unit 22 comprises a light receiver 220; Described light receiver 220 be positioned at receiver hole 210 under.
Vertical light-emitting source 11 is used for launching the light beam of vertical direction downwards, and the aperture size of being launched is adjustable.Adjustable support 12 is fixed on the dolly body of driving, the left and right deviation direction and the front and back offset direction in adjustable support 12 scalable vertical light-emitting sources 11, guarantee that vertical light-emitting source 11, receiver hole 210, light receiver 220 are positioned on the straight line, the light that send in vertical light-emitting source 11 is transmitted on the light receiver 220 by behind the receiver hole 210.
The below that light receives the reception warning box 21 of warning device 2 is provided with a plurality of magnet 25, and described magnet 25 is connected by bolt 23 with the bottom that receives warning box 21.Magnet 25 is to be used for the fixed installation that light receives warning device 2.Light receives warning device 2 and is installed on lifting hook pulley 3 cases top, and suspension hook inclination alarming device of the present utility model as shown in Figure 2 is installed in the scheme drawing on the suspension hook.Magnet 25 can be pull-in on lifting hook pulley 3 cases of circular arc easily, and can not destroy original structure, and easy installation and removal.
On the bolt 23 that connects reception warning box 21 and magnet 25, spring 24 is arranged, can avoid strong vibrations, play buffer action.
Arrive photodiode DU when the illumination that send in vertical light-emitting source 11, photodiode DU is the low-resistance conducting, and the base stage of VT1 is added with positive bias voltage and conducting, VT2 is conducting also, relay J is inhaled, and the normally closed contact J1 of relay J disconnects, and power supply V can't be added on the warning circuit 400.As the unglazed photodiode DU that shines when going up, be high resistance in the photodiode DU, VT1 does not have positive bias voltage and ends, VT2 also ends, and VT3 does not have positive bias voltage yet and ends, and relay J is not inhaled, its normally closed contact J1 energized V, VT4, VT5 alternate conduction and end.When VT5 Qi Ji earth polar above earth potential near 0V, the base potential of VT6 is also near 0V, VT6, VT7 end, alarm lamp RL does not work.Along with the concussion of multi resonant oscillator 300, alarm lamp RL sends warning light in continuous flicker.
Suspension hook inclination alarming device of the present utility model, under normal condition, when promptly suspension hook did not have run-off the straight, light was vertically downward sent in vertical light-emitting source 11, behind receiver hole 210, was transmitted into light receiver 220 and was on the photodiode DU among Fig. 3.When " askew skewing hung " phenomenon occurring when the suspension hook run-off the straight, light receiver 220 does not receive the light that send in vertical light-emitting source 11, and the light control alarm unit 22 that light receives warning device 2 sends the light of flicker, to show warning.
The suspension hook slant range that needs to report to the police can be set as required, can come setting range by the beam size in adjusting vertical light-emitting source 11 and the size of receiver hole 210.
