As shown in Figure 1, anchor fitting 5 is linked to each other with the bottom of equalizing bar 7.Anchor fitting 5 has bearing support 11 and stop pin 12.The upper surface of bearing support 11 is linked to each other with equalizing bar 7, stop pin 12 is contained in the bearing support 11.An example that in Fig. 5, has shown anchor fitting 5.As shown in Figure 5, stop pin 12 can move along the vertical direction, and through moving down the underlying metal spare 21 that falls into the groove shape that is arranged on the ground, thereby can be with respect to ground fixed crane main body 1.Stop pin 12 receives control signal, for example, and through lever part 16 up-and-down movements.For example, the stop pin 12 of anchor fitting 5 receives the signal of earthquake detection and moves up.
As shown in Figure 1, shock absorbing apparatus 13 is arranged between crane main body 1 and the mobile devices 2, and alleviates the seismic force of the right angle orientation of going (vertical direction of direction is set with respect to the extension of track 20) of input crane main body 1.An example that in Fig. 2, has shown shock absorbing apparatus.Shock absorbing apparatus 13 is by swivel bearing 17,18, spring members 19, damping part 23 formations such as grade.The S. A. of swivel bearing 17,18 is in vertical direction with respect to the ground basal plane.Vertical extension with respect to track 20 of spring members 19 and damping part 23 is provided with direction in the vertical direction setting.Safety pin 24 (inhibition portion) is set on shock absorbing apparatus 13,, then cuts off the safety pin 24 of shock absorbing apparatus 13 if the seismic force of the right angle orientation of going of input shock absorbing apparatus 13 reaches more than the specified value.In addition, on shock absorbing apparatus 13, though show in the drawings,, be provided with: the device (the 2nd part for releasing) that perhaps cuts off safety pin 24 is extracted in the sensor (test section) and the pressure that detect the cut-out of safety pin 24 out.At this, the seismic force that cuts off the specified value of safety pin 24 for example is the seismic force of the second grade earthquake in " Ministry of Land, Infrastructure and Transport of the technical benchmark of port facilities of formulation makes (put down on March 26th, 19 Ministry of Land, Infrastructure and Transport make No. 15) ", " bulletin of the technical benchmark detailed rules and regulations of the port facilities of formulation (the putting down into No. the 395th, Ministry of Land, Infrastructure and Transport bulletin on March 28 in 19 year) ".
Then, with reference to Fig. 6, the action during to effect seismic force on the container handling crane of this form of implementation describes.Below, to container handling crane in cargo handing or during operation stops, with respect to track 20 or ground fixedly the situation of mobile devices 2 describe.
Container handling crane is in readiness for action so that can detect earthquake (step S1) during being fixed with the mode that does not move along the bearing of trend of track 20.Under the earthquake detection readiness for action, if taking place, the seismic force of the right angle orientation of going of earthquake and input shock absorbing apparatus 13 reaches more than the specified value, then cut off the safety pin 24 of shock absorbing apparatus 13.As a result, shock absorbing apparatus 13 start working (step S2).In addition, anti-skid device (step S3) is removed in the cut-out of the safety pin 24 through sensor shock absorbing apparatus 13.
At this,, detect the cut-out of safety pin 24 in the shock absorbing apparatus 13 through being arranged near the sensor the safety pin 24.The sensor that detects the cut-out of safety pin 24 is proximity transducer that relatively moves that for example can detection part or lever sensor etc.
In addition, anti-skid device is rail folder 3 and track brake 4.Rail folder 3 is when detecting safety pin 24 cut-outs, and the hydraulic gear action is to remove the clamping of track 20.In addition, track brake 4 is removed pushing track 20 upper surfaces when detecting safety pin 24 cut-outs.In addition, for the releasing of track brake 4, can remove being connected of pin 15 between the bearing support 9 that is arranged on track brake 4 and the braking parts 10.As stated, container handling crane is removed by what anti-skid device formed and is fixed, thereby can move along track 20.
Therefore; When earthquake takes place, be provided with for extension for the seismic force of vertical direction of direction, through shock absorbing apparatus 13 actions with respect to track 20; Container handling crane obtains the shock-absorbing effect; Even be provided with for extension for the seismic force of parallel direction of direction with respect to track, the cliding friction through track 20 and the wheel 22 of mobile devices 2 or be arranged on the friction of the drg of wheel drive portion, container handling crane obtains the shock-absorbing effect.
In the past, mobile devices 2 were sailed for direction slides for following, and stoped through rail folder 3, acted on the hoisting crane travel direction until the earthquake load that reaches the safety pin degree of cutting off connecting portion 8.In addition, in the prior art, though at the safety pin that cuts off connecting portion 8 through the input of seismic force; Thereby when removing mobile devices 2 and rail and pressing from both sides 3 be connected; Can obtain the shock-absorbing effect of travel direction, still, the possibility that exists mobile devices 2 to move and conflict with rail folder 3 along track 20.
Yet according to this form of implementation, owing to removed rail folder 3 fixing for track 20, therefore, even mobile devices 2 move and conflicts with rail folder 3 along track 20, rail folder 3 also can move along track 20 while, thereby can reduce the damage to mobile devices 2.
[the 2nd form of implementation]
In the 1st form of implementation, the situation of removing anti-skid device with shock absorbing apparatus 13 with respect to the action of the seismic force of the vertical direction of the bearing of trend of track 20 as triggering has been described.In the 2nd form of implementation, then remove anti-skid device as triggering with seismic force with respect to the parallel direction of the bearing of trend of track 20.Fig. 7 is for showing the diagram of circuit of the action of hoisting crane in this form of implementation.
At first, container handling crane is in readiness for action so that can detect earthquake (step S11) during the mode that does not move with the bearing of trend along track 20 is fixed.Under the earthquake detection readiness for action, if taking place, the seismic force of the travel direction of the connecting portion 8 between earthquake and input mobile devices 2 and the rail folder 3 reaches more than the specified value, then cut off the safety pin (step S12) of connecting portion 8.As a result, mobile devices 2 can move along track 20, through the cliding friction of track 20 with the wheel 22 of mobile devices 2, obtain the shock-absorbing effect.
Afterwards, the safety pin 24 (step S13) of shock absorbing apparatus 13 is removed in the cut-out of the safety pin through sensor connecting portion 8.The result; When earthquake takes place; Even do not reach more than the specified value and do not cut off under the situation of safety pin 24 of shock absorbing apparatus 13 at the seismic force of the right angle orientation of going of input shock absorbing apparatus 13; As triggering, remove the safety pin 24 of shock absorbing apparatus 13 with the cut-out of the safety pin of connecting portion 8, shock absorbing apparatus 13 is started working.
At this, identical with the situation of safety pin 24 in the shock absorbing apparatus of the 1st form of implementation, through being arranged near the sensor the safety pin, detect the cut-out of the safety pin in the connecting portion 8.In addition, through the mechanism that forces to extract out or cut off safety pin 24 is set in shock absorbing apparatus 13, make this mechanism action, thereby can carry out the releasing of the safety pin 24 of shock absorbing apparatus 13.
Afterwards, when the cut-out of the safety pin that passes through sensor connecting portion 8, remove anti-skid device (step S14).Anti-skid device is the same with the 1st form of implementation, is rail folder 3 and track brake 4.
Therefore, when earthquake takes place, be provided with for extension for the seismic force of parallel direction of direction with respect to track 20; Remove the connection of connecting portion 8; Mobile devices 2 can move, and through the cliding friction between the wheel 22 of track 20 and mobile devices 2, container handling crane obtains the shock-absorbing effect.In addition, through the safety pin 24 of compulsory commutation shock absorbing apparatus 13, shock absorbing apparatus 13 action, thus, container handling crane is provided with for the extension with respect to track 20 for the seismic force of vertical direction of direction, also can obtain the shock-absorbing effect.
In addition,, thereby when removing being connected of mobile devices 2 and rail folder 3, obtain the shock-absorbing effect of travel direction though the safety pin of connecting portion 8 is cut off in the input of brisance in the stronghold,, exist mobile devices 2 to go and press from both sides 3 possibilities of conflicting with rail along track 20.Yet, according to this form of implementation, owing to removed rail folder 3 fixing for track 20, therefore, even mobile devices 2 move along track 20, so that conflict with rail folder 3, rail folder 2 also can move along track 20 while, thereby can reduce the damage to mobile devices 2.
[the 3rd form of implementation]
Though in above-mentioned the 1st form of implementation, the 2nd form of implementation, the rail folder 3 in the releasing anti-skid device and the situation of track brake 4 are illustrated,, should not be limited to example of the present invention.For example, when earthquake takes place, can remove anchor fitting 5.Fig. 8 is a diagram of circuit, and it has shown the action of the hoisting crane of this form of implementation.
At first, container handling crane is in readiness for action so that can detect earthquake (step S21) during being fixed with the mode that does not move along track 20.Under the earthquake detection readiness for action, if taking place, the seismic force of the right angle orientation of going of earthquake and input shock absorbing apparatus 13 reaches more than the specified value, then cut off the safety pin 24 of shock absorbing apparatus 13.As a result, shock absorbing apparatus 13 is started working.Perhaps, under the earthquake detection readiness for action, if earthquake takes place, the seismic force of the travel direction of the connecting portion 8 between input mobile devices 2 and the rail folder 3 reaches more than the specified value, then cuts off the safety pin (step S22) of connecting portion 8.
Afterwards, when the cut-out of the safety pin of safety pin through sensor shock absorbing apparatus 13 24 or connecting portion 8, remove anchor fitting 5 (step S23).As a result, mobile devices 2 can move along track 20, through the cliding friction between the wheel 22 of track 20 and mobile devices 2, obtain the shock-absorbing effect.Therefore, on the basis of rail folder 3 and track brake 4, passing through under the situation of anchor fitting 5 with respect to the ground fixed crane, when earthquake took place, hoisting crane can be provided with direction and move towards the extension of track 20.
In addition, the anti-skid device rail folder 3, track brake 4 and the anchor fitting 5 that are not limited to be arranged in 2 minutes with mobile devices.For example; Anti-skid device can be to the mechanical brake or the motor brake that are arranged on the wheel 22 on the mobile devices 2; So that when the safety pin of safety pin 24 that passes through sensor shock absorbing apparatus 13 or connecting portion 8 cuts off, can remove these anti-skid devices.
Above, according to this form of implementation, because because of the anti-skid device of having removed of earthquake, therefore, the wheel 22 of the mobile devices 2 through container handling crane and the cliding friction of track 20 etc. can absorb and alleviate vibration, thus the shock-absorbing effect of acquisition travel direction.In addition, through shock absorbing apparatus 13, the shock-absorbing effect of the right angle orientation that also can obtain to go.In the past, though owing to can obtain, not have the go shock-absorbing effect of right angle orientation of fully acquisition towards going the shock-absorbing effect of right angle orientation; Therefore; Follow under the situation of sailing direction or direction of tilt input at seismic force, on crane main body 1, can produce distortion, and produce distortion towards travel direction.Therefore; On the shock absorbing apparatus 13 that is used to obtain to the shock-absorbing effect of the right angle orientation of going, add sliding stroke in addition; Then can cause the out-of-action bad phenomenon of shock absorbing apparatus 13 self, perhaps, even given play to the situation that ability wheel 22 to greatest extent still can float.On the other hand, according to this form of implementation,, therefore, can prevent above-mentioned unfavorable condition owing in fact can tackle the earthquake of all directions.
In addition, according to the present invention,, needn't use the special device as shock absorbing apparatus 13 in order to tackle earthquake from all directions.When the device of device, compulsory commutation safety pin 24 of releasing of safety pin of the safety pin 24 that detects shock absorbing apparatus 13, connecting portion 8 was set, the control logic that only changes rail folder 3, track brake 4 and anchor fitting 5 got final product, and, can cost-cutting.In addition, even under the situation of improving the hoisting crane that has been provided with, also need not large-scale improvement, can realize improving with short time and low cost.
In above-mentioned form of implementation, as the detection of earthquake, though the situation of the safety pin of the safety pin 24 that used shock absorbing apparatus 13 or connecting portion 8 is illustrated,, also can consider other form of implementation.For example, can use the vibration detection that realizes through seismograph or weight, press from both sides the anti-skid device of 3 grades to remove rail.But, in the detection that realizes through seismograph or weight,, therefore, exist owing to erroneous detection makes the moving situation about being disengaged that prevents to expect of slipping owing to exist because of the situation that causes erroneous detection of rocking beyond the earthquake.In addition, because the essential device that uses beyond the shock absorbing apparatus such as seismograph or weight, therefore, unnecessary cost necessitates, so, caused uneconomic structure.Wind when in addition, the safety pin of the safety pin 24 of shock absorbing apparatus 13 or connecting portion 8 is not because of normal operation etc. cuts off.Therefore, the safety pin 24 through utilizing shock absorbing apparatus 13 or the safety pin of connecting portion 8 detect earthquake, the releasing of the anti-skid device that can avoid causing because of maloperation.
In addition, in the work of common container handling crane, if get into the halted state of going from motoring condition, then anti-skid device is worked automatically, so that with respect to the fixing container handling crane of track or ground.In order to realize this form of implementation, to hope in the going of container handling crane, to take place under the earthquake and the situation about stopping of going, anti-skid device is inoperative, even under the acting situation of anti-skid device, still can be through the detection releasing anti-skid device of earthquake.
