Detailed description of the invention
Technical scheme of the present invention is explained further below in conjunction with the drawings and specific embodiments.
The invention discloses a kind of two crossbeam shore container crane.Be different from traditional container handling crane and only have a cantilever beam, this container handling crane is provided with two cantilever beams across front and back entablatrance, and the spacing of these two cantilever beams is approximately equal to the spacing of adjacent compartment.On the hoisting crane of open side type supporting, entablatrance cantilever support is on single-column, and namely, entablatrance is respectively by the cantilever-shaped supporting of former and later two single-columns, and two cantilever beams described in this invention are positioned at the outer end of front and back entablatrance; And on the hoisting crane of door case type supporting structure, two cantilever beams described in this invention are then in entablatrance and are positioned in the part of doorframe, as shown in Figure 2.What adopt in this embodiment is the container handling crane that door case type as shown in Figure 2 supports.Wherein, 1 is freight container to be loaded and unloaded, and 2 is cantilever beam, and 3 is suspender, and 4 is entablatrance, and 5 is dolly, and 6 is doorframe column, and 7 is cart walking mechanism.
In this embodiment, two cantilever beams 2 of hoisting crane adopt truss structure, the cantilever beam not only lighter weight of this structure, and rigidity is also very strong, and this cantilever beam 2 also can adopt box-structure.Cantilever beam 2 is provided with track along jib direction, and during handling, this race orthogonal is in captain direction, and dolly 5 is connected in the track of cantilever beam 2 by the roller of top, can along the orbiting motion of cantilever beam 2.Be fixedly connected with a machine room in the below of dolly 5, the below of machine room is fixedly connected with translation mechanism.Translation mechanism is connected with suspender 3, this translation mechanism can be moved with the direction that suspender 3 is being parallel to captain by the method for hydraulic way or mechanical compensation, namely can realize the left and right sides movement flexibly of suspender, its moving range is for can reach 2.5 meters to the inside, and movement laterally can reach 0.5 meter.When dolly is walked along cantilever beam 2, control dolly by translation mechanism and move to Inner side, thus the interference and collision of freight container 1 or hatchway cover and doorframe column 6 can be avoided.
This container handling crane, according to the difference of operating mode, can be made into heavy and light-duty two kinds by the installation of suspender 3.Heavy duty crane installs the suspender 3 of single 40 feet on the cantilever beam 2, and the suspender 3 of two 40 feet then installed by light hoisting gear.When only installing single box hanger, the dolly on two cantilever beams 2 works simultaneously and can realize the capacity rating of 30 ~ 50 working cycle (also known as move) per hour; If installation double-box hanger, then capacity rating can be higher.
In order to make horizontal transport tool (as superimposed trailer, small-sized straddle carrier and unmanned floor truck AGV etc.) that cart and mistake can be passed through, being convenient to the freight container of rapid collecting and distributing transport handling, under side, the land cross sill of this hoisting crane, having 10-12 rice neutral gear.The load simultaneously transmitted than side, land doorframe due to extra large side door frame is large, so needs arrange that on the cart of extra large side more wheel is to bear weight.In addition, because side, land needs to leave neutral gear, come in and go out for horizontal transport tool, extra large side does not then have the discrepancy of horizontal transport tool, so the width of extra large side and side, land cart is not etc.The maximum width about 26 ~ 28 meters of side, sea cart, be covered with wheel under it, wheel number at about 20 ~ 24, and is only equipped with 16 wheels under the cart of side, land.
Consider the factor of wind, adopt different large vehicle walking type of drive according to the area that this hoisting crane uses, to ensure to come can have enough propulsive efforts to overcome the resistance of wind at strong wind temporarily.Because drive wheel number is more, propulsive effort is larger, and therefore in the place that wind is little, adopt 1/2 mode driven, namely the wheel of half is as drive wheel; In medium wind speed area, adopt 2/3 mode driven, namely the wheel of 2/3 number is as drive wheel; Often having the area of storm wind, adopt all-wheel powered mode, namely all wheels are drive wheel.
This container handling crane is not more than the overall width of adjacent compartment along the width in captain direction, is generally less than 28 meters.This feature makes two these container handling cranes to draw close and loads and unloads each cabin successively.As cranage first cabin and the second cabin, another hoisting crane drawing close with it work then can load and unload the 3rd cabin and the 4th cabin simultaneously.If there is the hoisting crane that multiple stage is such, then can loads and unloads each cabin of full ship successively simultaneously, thus substantially increase the efficiency of handling.
This pair of crossbeam shore container crane is when operating, and complete machine high voltage supply, leaky wave communication, adopts semi-automatic control method.Whole working process, by computer controlled, is guarded by people, and whole process only needs a driver operation two dollies and monitors its work.
When this container handling crane lifts by crane the adjacent compartment freight container of ship, a working cycle can have been carried out: first hoisting crane is moved to correct position by following method, namely two arms aim at the center of two cabins, and automatic carriage moves to the position that freight container aimed at by suspender.Now transfer suspender, freight container is contained on suspender.Then lift by crane one of them suspender to certain altitude, make the position of the freight container on this suspender higher than another one freight container, ensure not interfere in next step translation.Lift by crane another suspender more afterwards, two suspenders upwards run together, until after the container height sling higher than the height of obstacle in its range of movement.Subsequently, the suspender under the effect of translation mechanism under dolly and goods along perpendicular to the inside translation in cantilever beam direction 1 meter, the then inwardly translation 2.5 meters when gondola cover plate.Finally, self-traveling trolley drives suspender and goods to move to assigned address goods putting thing at present along cantilever beam direction, completes a working cycle.
As shown in Figure 1, conventional container handling crane only has a cantilever beam, and hoisting crane itself is generally 27 ~ 30 meters along the width in captain direction, and when therefore work drawn close by two conventional container handling cranes, the distance between its cantilever beam is also 27 ~ 30 meters usually.And the spacing of the adjacent compartment of conventional ship is 13.5 ~ 14.5 meters, therefore cantilever beam spacing is that two container handling cranes of 27 ~ 30 meters cannot load and unload adjacent compartment by drawing close work simultaneously.In conventional ship a midfeather cabin two cabins between spacing be generally 25 ~ 29 meters, therefore traditional container handling crane can only load and unload at most the goods that middle ware is separated with two cabins of a cabin simultaneously.In of the present invention pair of crossbeam shore container crane, on the front and back entablatrance of container handling crane, cantilever-shaped installation two cantilever beams, these two cantilever beams are vertical with entablatrance, and spacing is depending on the spacing of adjacent compartment, be generally about 14 meters, thus the function that use one this pair crossbeam shore container crane can load and unload adjacent compartment goods simultaneously can be realized, as shown in Figure 4.
Simultaneously, because this pair of crossbeam shore container crane to be less than or equal to the overall width of adjacent compartment along the width in captain direction, thus two or this container handling crane of multiple stage can be drawn close work, realize loading and unloading the function that multiple adjacent compartment loads and unloads full hold cargo thing even simultaneously simultaneously, substantially increase handling efficiency.
Above-mentioned is can understand and apply the invention for ease of those skilled in the art to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to embodiment here, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
