Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 3 and Figure 4, a kind of container handling crane, comprise door frame, crossbeam, machine house 2, traveling mechanism of the larger traveller 3, door frame is mainly used in supporting container handling crane, comprise the first doorframe 11, the second doorframe 12, ladder frame 16, first crossbeam 15 and second cross beam 17, first crossbeam 15 is arranged at the upside of the first doorframe 11, and second cross beam 17 is arranged at the upside of the second doorframe 12; Crossbeam is mainly used in dynamical element, wheeling mechanism and the suspender etc. of bearing container hoisting crane, comprises the first crossbeam 13 and the second crossbeam 14; Traveling mechanism of the larger traveller 3 is arranged at the bottom of this door frame, is specifically arranged on the bottom of the first doorframe 11 and the second doorframe 12.In the time of the operation of container handling crane bank, the first doorframe 11 is near extra large side, and the second doorframe 12 is near land side.This machine house 2 is arranged on the second crossbeam 14, and near second cross beam 17, machine house 2 is supported jointly by the second crossbeam 14 and second cross beam 17.Container handling crane also comprises the oil cylinder 1 that drives the first crossbeam 13 to do luffing, and oil cylinder 1 is arranged at the outside of machine house 2, has significantly reduced the area of machine house 2, and this oil cylinder 1 one end is connected with the first crossbeam 13.As shown in Figure 3 and Figure 4, ladder frame 16 is located at the two ends of plane on first crossbeam 15, and first crossbeam 15 is fixedly connected with this ladder frame 16.
It should be noted that, above-mentioned oil cylinder 1 can substitute with cylinder, but in view of the working pressure of cylinder is generally at 0.2-1.0Mpa, cylinder generally can not do high-performance dynamical element, so the utility model preferably adopts oil cylinder 1 to drive the first crossbeam 13 to do luffing.
As shown in Figure 5, be provided with lifting mechanism 5 in machine house 2, it should be noted that, compared to existing technology, luffing mechanism is no longer arranged in machine house 2, reduces for the regulator cubicle that drives this luffing mechanism, and machine house takes up an area space also to be reduced.
As shown in Figure 3 and Figure 4,1 one kinds of embodiment of oil cylinder can be arranged on ladder frame 16, and another kind of embodiment can be arranged on first crossbeam 15.As shown in Figure 3, be oil cylinder 1 and be arranged at the embodiment of ladder frame 16.Now, oil cylinder 1 one end is connected with ladder frame 16, and the other end is connected with the first crossbeam 13.As shown in Figure 4, be oil cylinder 1 and be arranged at another embodiment of first crossbeam 15.Now, oil cylinder 1 one end is connected with first crossbeam 15, and the other end is connected with the first crossbeam 13.
As shown in Figures 3 to 8, container handling crane is provided with dolly 6, and dolly 6 is arranged on above-mentioned crossbeam, and can on this crossbeam, move.In the embodiment shown in Fig. 3 and Fig. 4, dolly 6 does not need external force to drive, and can on above-mentioned crossbeam, move voluntarily.In embodiment as shown in Figure 6 and Figure 7, dolly 6 moves under external force drives on crossbeam, and as shown in Figure 8, outer force driving device is trailer coupling 7, and this trailer coupling 7 is arranged in machine house 2.In above-mentioned two kinds of embodiment, compare prior art, the equipment in machine house 2 reduces, complete machine weight saving, and wheel load also reduces.It should be noted that the specifically operation on the first crossbeam 13 and the second crossbeam 14 of above-mentioned dolly 6.
As shown in Fig. 3, Fig. 4 and Fig. 6, the first crossbeam 13 is provided with pull bar 10, and these pull bar 10 one end are connected with the first crossbeam 13, and its other end is connected with ladder frame 16.In the time of container crane job, for ensureing that pull bar 10 can draw high the first crossbeam 13 better, the connection mode of pull bar 10 and the first crossbeam 13 and ladder frame 16 is preferably hinged.According to front lift difference, the quantity of pull bar 10 is not limited to one, can be many.As shown in Figure 8, in the situation that front lift is less, available above-mentioned oil cylinder 1 replaces the effect of pull bar 10, thereby cancels the pull bar 10 of traditional form.
Set forth in the utility model the principle of work of container handling crane below:
Oil cylinder 1 is placed on ladder frame 16 or first crossbeam 15, in oil cylinder 1, be provided with piston rod, when container handling crane work, the first crossbeam 13 is horizontal, piston rod is in the time stretching out state, the first crossbeam 13 is produced to pulling force upwards, and with respect to traditional bank bridge of same specification, it has increased front lift; When container handling crane is during in off working state, oil cylinder 1 moves, and piston rod shrinks the first crossbeam 13 is steeved.Realize the luffing (being luffing) of the first crossbeam 13 by hydraulically powered mode, thereby substituted traditional pitching motor driver train and pitching winding system, the corresponding minimizing of electrical equipment, corresponding the reducing of machine house 2 areas.Because a whole set of hydraulics weight and pitching winding system weight approach, in the situation that reducing pitching motor driver train, complete machine weight saving, wheel load reduces.Due on the first crossbeam 13 without pitching pulley, corresponding maintenance crane also can omit, the first crossbeam 13 weight savings reduce near the wheel load of extra large side, complete machine stability strengthens.For the less container handling crane of front lift, as previously mentioned, can replace with oil cylinder 1 effect of pull bar 10.
The disclosed a kind of container handling crane of the utility model, replace traditional motor to drive for driving the first crossbeam 13 to carry out luffing with oil cylinder 1 or cylinder, reduced equipment cost on the one hand, reduced on the other hand the space of machine house, complete machine weight is reduced, and wheel load reduces.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
