Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 2 and Figure 3, wind-proof device of the present utility model includes the stopper that two nested structures are identical, and often set stopper all includes: pedestal 5, countercheck rod 6, the first hydraulic cylinder 7, tilting bar 8, second hydraulic cylinder 9, buffer stopper 10, infrared holes probe 11, buzzer 12, plc single board computer 13, two motor contactor 14, motor 15, hydraulic pump 16, framework 17；nullPlc single board computer 13，Two motor contactor 14、Motor 15 and hydraulic pump 16 are all contained in the framework 17 on pedestal 5 top，First hydraulic cylinder 7 and the second hydraulic cylinder 9 are separately mounted to the both sides of framework 17 upper surface，One end of first hydraulic cylinder 7 and the second hydraulic cylinder 9 is hinged with framework 17 upper surface respectively，Buffer stopper 10 is installed in the lower surface stretching out countercheck rod 6 end points outside the first hydraulic cylinder 7，The countercheck rod 6 stretching out tilting bar 8 end points outside the second hydraulic cylinder 9 and the first hydraulic cylinder 7 is hinged，Stretching of tilting bar 8 outside second hydraulic cylinder 9，The countercheck rod 6 that can make the first hydraulic cylinder 7 rotates around the first hydraulic cylinder 7 pin joint，Buzzer 12 is arranged on framework 17 upper surface，Infrared holes probe 11 is arranged on framework 17 side，Infrared holes probe 11 and the second hydraulic cylinder 9 are positioned at homonymy；Plc single board computer 13 electrically connects with buzzer 12, infrared holes probe 11 and two motor contactor 14 respectively, and motor 15 drives described first hydraulic cylinder 7 and the second hydraulic cylinder 9 to work through hydraulic pump 16.
The countercheck rod 6 of the first hydraulic cylinder 7 is 0 °～75 ° around the angle that the first hydraulic cylinder 7 pin joint rotates.
The pedestal 5 of the stopper that two nested structures are identical is arranged on after two pieces of stop blocks 3, and the countercheck rod 6 of two the first hydraulic cylinders 7 is respectively aligned at crane two supporting leg 1 dead ahead, and two infrared holes probes 11 are respectively facing crane two supporting leg 1 dead ahead.
Working depth when buffer stopper 10 works is necessarily located at the position of centre of gravity of large-sized gantry and port gantry crane.
Operation principle of the present utility model:
When large-sized gantry and port gantry crane run into the huge wind of more than typhoon (32.7-36.9m/s), under the effect of the wind load load forces that the bigger front face area of cause is subject to, overcome the frictional resistance that the load corresponding with the frictional force that transmission efficiency does not considers of the brake load in drive mechanism and crane cart wheel 2 roll along track to run to downwind, form kinetic energy Ev=1/2mV due to crane deadweight2, Ev crane kinetic energy (J) in formula, m total mass (kg), the V crane speed of service (m/s).
As shown in Figure 2 and Figure 3, when speed V overcoming the crane of various resistance not skid with cart wheel 2 and track is walked to two rail end, and stopper mid-infrared holes probe 11 issues a command to buzzer 12 warning respectively and stopper makes its work.
Stopper, after receiving actuating signal, makes motor 15 obtain electric by motor contactor 14 thus starts hydraulic pump 16, make the first hydraulic cylinder 7 and the second hydraulic cylinder 9 work.Countercheck rod 6 and tilting bar 8 hoist the most obliquely upward at Hydraulic Cylinder, both sides stop head 6 head equipped with buffer stopper 10 act simultaneously on two supporting legs 1 in crane, and near crane topples line.
Such as Fig. 1, shown in Fig. 2, the effect of the wind-proof device of large-sized gantry and port gantry crane is: when running into huge wind in a non-operative state, crane is under the effect of wind load, original wind-proof device and electrically, the reverse resistance that mechanical braking etc. produce is unlikely to hinder cart wheel 2 quickly to run to rail end, the wind-proof device mid-infrared holes probe 11 of monitoring measures numerical value and plc single board computer 13 setting value (after crane clashes into original end snubber 4 and backstop 3 in real time, not by the speed of stop), when overflowing, send signal and trigger catalyst 14 action of wind-proof device, actuating motor 15, hydraulic pump 16 is made to work.It is in the both sides countercheck rod 6 of level and tilting bar 8 at ordinary times under respective hydraulic cylinder 7,9 acts on, has synced up and risen to crane height of C.G..
When crane is with kinetic energy Ev=1/2mV2The buffer 4 of the original crane of speed impacts and backstop 3 after, consume big portion kinetic energy.The still crane of remaining kinetic energy, runs outside backstop with speed v, surmounts the kinetic energy Ev=1/2mv that the line that topples is formed2The potential energy Ea=mgh wherein h--constituted with crane center of gravity and backstop 3 spacing topple on line crane center of gravity with backstop 3 apart from (rice), v crane be knocked after the big vehicle speed (m/s) that formed of remaining kinetic energy.Wind-proof device effect is to have acted on crane two supporting leg height of C.G. by risen, formed by countercheck rod 6, tilting bar 8 and pedestal 5, more than kinetic energy, the moment of potential energy composition tilting moment, it is achieved wind-proof device prevents large-sized gantry and the port gantry crane huge wind of chance from tumbling.
Wind-proof device resistance to tipping moment of the present utility model according to shown in Fig. 2, the moment of antidumpingFor ensure this utility model wind-proof device formed because of moment of torsion at B point bending resistance, shearing strength, safety coefficientSuggestion takes 1.2.
In formula:
F acts laterally on the wind-force (N) on crane；
The height of C.G. (m) of h crane；
L crane centrage and the spacing (m) of backstop；
Ev crane kinetic energy (J)；
Ea crane potential energy (J)；
