Fig. 5 and 6 schematically illustrates the moving with pylon crane hanging component container of the embodiment of the invention Make process. For explaining conveniently,

several winches

106 and 108 are shown, but in fact as previously mentioned, One that settles is that 106, one in bank winch is seashore winch 108.

Fig. 5 represents to arrive the crane 102 under the bank winch 106 and ties the behaviour of hanging cable hanging beam 104 Make process. Above-mentioned those identical identical parts of reference number indication.

With reference to figure 5, crane 102 and bundle hanging cable hanging beam 104 edges that are coupled to crane 102 lower surfaces When moving along the direction shown in the arrow b, be maintained at bank winch 106 below. As previously mentioned, The protuberance 124 of crane 102 inserts and is coupled to formed the hanging of bundle hanging cable hanging beam 104 upper surfaces In the car hole 126, like this, even the movement velocity of crane 102 changes, bundle hanging cable hanging beam 104 also Can be not safe being positioned under the crane 102 unsteadily.

Bank winch 106 is by pre-aligned, and waits straight above container 150. At this moment, Suspension hook 116 is attached to the lower surface of winch 106, and remains on eminence as far as possible. Pass through the operator Direct control be arranged on each

winch

106 and 108 in independent control room (not shown), the bank and

Seashore winch

106 and 108 namely is moveable to certain position. Perhaps in another way, by far Process control makes

winch

106 and 108 move to certain position.

Bank winch 106 waits straight above container 150, and the seashore winch 108 of Fig. 6 Wait straight above certain position on the ship 130 of Fig. 6, container there is to prepare to be hung Dress. Therefore, preferably should be according to the position of the container that is loaded by container carrier in advance The position of control bank winch 106, and wait below crane arm; Should make the seashore winch equally 108 are located in the top, position that container will be lifted.

When crane 102 arrive the bank winch 106 waited in certain position below the time, as far as possible The suspension hook 116 that is attached on the winch 106 begins to descend. Suspension hook 116 is by 100 of crane arms The crane 102 of supporting descends along vertical, and arrives bundle hanging cable hanging beam 104. When suspension hook 116 arrives During bundle hanging cable hanging beam 104, as previously mentioned, the formed protuberance 125 of suspension hook 116 lower surfaces is inserted Enter to tie the formed hook on hole 128 of hanging cable hanging beam 104 upper surfaces. Like this, suspension hook 116 is coupled To bundle hanging cable hanging beam 104.

Meanwhile, along with suspension hook 116 is incorporated in to bundle hanging cable hanging beam 104, by crane 102 On the separating of protuberance 124 and bundle hanging cable hanging beam 104 upper surfaces formed crane hole 126, Bundle hanging cable hanging beam 104 from crane 102 separately. Therefore, along with the decline of suspension hook 116, bundle is hung The holding power that rope hanging beam 104 is draped is transferred to suspension hook 116 from crane 102. At this moment, bundle hanging cable Hanging beam 104 is maintained at sustained height.

By top said various known effective ways, can realize turning to of described holding power Move. For example, signal transmssion line is not (arbitrarily to install one between crane hole 126 and hook on hole 128 Illustrate). When protuberance 124 was inserted into and is locked in the crane hole 126, a signal was sent out To hook on hole 128, the protuberance 125 that control had been inserted into and had been locked in hook on hole 128 therefrom Be unlocked. On the contrary, when protuberance 125 is inserted into and is locked in the hook on hole 128, with above-mentioned Same method, be inserted into and be locked in the crane hole 126 protuberance 124 will be therefrom by Discharge.

Protuberance

124 and 125 comprises several known door bolt bolts.

As mentioned above, descend and be coupled to bundle hanging cable hanging beam 104 at suspension hook 116, tie simultaneously hanging cable Hanging beam 104 is by under the state of release from crane 102, by winch motor 110 and winch flywheel 112 continuous operation, suspension hook 116 descends towards container 150, accompanies by bundle hanging cable hanging beam 104 Lifting. Pulley 132 is installed in the upper surface of suspension hook 116, and is twined by steel cable 114, hangs Hook 116 is therefore supported. By the driving of winch motor 110, steel cable 114 is from pulley 132 On be released, therefore suspension hook 116 descends.

Lower surface at bundle hanging cable hanging beam 104 forms container suspension hook 120, at container 150 Upper surface forms known conjugate foramen 122, is used to engage with container suspension hook 120.

When bundle hanging cable hanging beam 104 descends and arrives container 150, the collection of bundle hanging cable hanging beam 104 Vanning suspension hook 120 is inserted into and is locked in the formed conjugate foramen 122 of container 150 upper surfaces. At this moment, suspension hook 116 straight lines land downwards, so it can not wave on both sides. In this state, When suspension hook 116 rose, bundle hanging cable hanging beam 104 rose container because being attached to suspension hook 116 150 are raised thereupon.

When suspension hook 116 rises continuously, when bundle hanging cable hanging beam 104 arrives the lower surface of cranes 102, Protuberance 124 on crane 102 lower surfaces is inserted in the crane hole 126 of bundle hanging cable hanging beam 104, Therefore

crane

102 and 104 combinations of bundle hanging cable hanging beam. At this moment, suspension hook 116 is from bundle hanging cable hanging beam 104 Throw off, continue to rise to the lower surface of bank winch 106, and the lower surface place there waits. At last, bundle hanging cable hanging beam 104 and container 150 are coupled to by crane arm 100 supports and move Crane 102 lower surfaces, thereby make the container 150 can be to container 150 with the place that is loaded Motion is indicated this direction of motion with the arrow C that represents crane 102 motions.

Fig. 6 represents to arrive crane below the winch of seashore and the course of action of bundle hanging cable hanging beam. Ginseng Examine Fig. 6, container 150 is transported to seashore winch 108 by the arrow C indicated direction from the bank Following standby, and seashore winch 108 is pre-aligned on the position that container will be loaded The side. Can be by being included in the control of the operator in the operation room (not shown) in the winch 108, Make seashore winch 108 in advance passive movement to the loading point. Thereby it can install to container the suitable of it Work as the place, and irrelevant with the zone of loading point. Seashore winch 108 also can be by separately operation Between Long-distance Control, this is similar to the situation of bank winch 106.

When crane 102 arrive seashore winches 108 below the time, bundle hanging cable hanging beam 104 and container 150 just be positioned in seashore winch 108 below, be in the suspension hook 116 of wait state by strand Vehicle and horse reach 110 operation and descend, and are coupled to bundle hanging cable hanging beam 104. As top with reference to figure 5 Said like that, when suspension hook 116 is coupled to bundle hanging cable hanging beam 104, bundle hanging cable hanging beam 104 from Crane 102 is thrown off. Therefore, when suspension hook 116 continues to descend under this state, bundle hanging cable hanging beam 104 from crane 102 disengagements, and container 150 drops to the loading point, and for example ship 130.

The container 150 that arrives the loading point takes off from bundle hanging cable hanging beam 104 by known method Open, and be loaded on the ship 130, bundle hanging cable hanging beam 104 vertically rises again, and coupling Be coupled to crane 102. Simultaneously, suspension hook 116 separates from bundle hanging cable hanging beam 104, towards winch 108 Rise, and wait under winch 108 lower surfaces by the sea. The suspension hook 116 crane 102 theres Through throwing off, bundle hanging cable hanging beam 104 is coupled to crane 102, and crane 102 is from seashore winch 108 times The three unities of face moves by the arrow d indicated direction along crane arm 100, and is positioned in Initial position. Simultaneously, seashore winch 108 moves to next container along crane arm 100 and wants The place that is loaded, and that local wait.

Fig. 7 is that plane of giving an example of pylon crane that explanation the present invention has a circulating crane shows Intention. As shown in Figure 7, crane arm circularizes, so that crane 102 is along this crane arm shuttling movement. Because crane 102 circulates along crane arm in a direction, thus carry out continuously the loading of container, The pylon crane has very fast disposal ability.

But the crane arm of pylon crane of the present invention can have various shape, as long as its tool The structure that crane is circulated is therein arranged. Therefore, except annular crane arm, various shapes Crane arm can both be applied to the vertical circulation formula pylon crane shown in Fig. 2 and Fig. 3.

In the pylon crane that contains above-mentioned crane arm according to the present invention, a plurality of cranes are along rising Loading container in the time of the weighing arm shuttling movement, so loading/unloading speed is very fast, treatment effeciency also very High. In addition, during trolley movement be the bundle hanging cable hanging beam that combines with it, rather than Overhanging the bundle hanging cable hanging beam under the crane, so, can not take place because the trolley movement velocity variations is drawn Play the situation that bundle hanging cable hanging beam waves, thereby can make bundle hanging cable hanging beam be positioned fast accurate place. Even bundle hanging cable hanging beam moves when picking up container, and container can not wave yet, and has therefore improved The movement velocity of crane. Therefore, can realize fast and stably the loading/unloading of container.

Although described the present invention with reference to specific embodiment, clearly, common for this area The technical staff can do multiple remodeling to described embodiment, and unlikelyly departs from essence of the present invention God and scope.
