As shown in the figure: 3 is the female frame of suspender, the freight container that can be used for 20 feet of handlings, the sub-frame of suspender does not provide in the accompanying drawings, the difference of sub-frame and female frame is do not have cable winder 4 and pulley 5 in the sub-frame, in addition, sub-frame is used for the freight container of 40 feet of handlings, during use, sub-frame is connected under female frame, therefore sub-frame top have with 20 feet freight container on identical corner fittings, so that the latch mechanism that revolves of four jiaos on female frame inserts assembling in the corner fittings, adorn 4 equally on four jiaos on sub-frame and revolve latch mechanism, be used for being connected with 40 forty equivalent unit 40s.also have on four angles of suspension hook 30 4 with 20 forty equivalent unit 40s on identical corner fittings 29, on suspension hook 30, use wirerope 31 coupling hooks 27, as shown in Figure 7, the figure middle and upper part is female frame 3, and the bottom is that suspension hook 30,26,28 is respectively wirerope, above-mentioned corner fittings is actually one and hangs the hole, accentric revolves in tapered end 30 these holes of insertion and just can not withdraw from after rotation one angle again in revolving latch mechanism, has only when revolving and can extract when tapered end recovers to rotate to original position, thereby play interconnect function.Tell about in detail below and revolve latch mechanism and pushing mechanism.

Latch mechanism 1 is revolved in four jiaos of 4 of installations at the female frame 3 of container spreader, and install two groups respectively at the two ends of female frame and be used for the pushing mechanism that driven in synchronism is revolved latch mechanism, the guide piece 2 of being convenient to revolve the corner fittings aligned position on latch mechanism and the freight container is installed in both sides at female frame 3, cable winder 4 is arranged, also uniform 4 pulleys 5 on suspender at female frame middle part.

In pushing mechanism, the electronic cylinder 8 that is installed on female frame 3 is connected with expansion link 7, the movable end of expansion link 7 is hinged with the connecting rod 6 that is connected in shifting bar 10 middle parts, and shifting bar 10 is installed on the suspender 3 movably, and its two ends are hinged with two forks 13 that revolve in the latch mechanism 1 respectively.

In revolving latch mechanism 1, casing 11 is installed on the female frame 3 of container spreader, support 18 is arranged in the casing, on, following two ends are cover plate and base plate, the middle part of revolving lock shaft 20 utilize thrust baring 17 and on,

lower cover

14,16 connect with support 18, above the bearing upper cover 14 is fork 13, jam nut 12 is fastened on fork and thrust baring on the support, make that to revolve lock shaft rotatable but can not go up, move down, the lower end of revolving lock shaft 20 is the oblong tapered end 22 that revolves, and during use, revolving that tapered end stretches on the freight container with the decline of suspender is oblong hanging in the hole equally, driving backspin at pushing mechanism turn 90 degrees again, just can tangle freight container.

Side in casing 11 has a push rod 21 that passes support 18 and base plate respectively, flange is arranged at the bottom that is positioned at casing at push rod 21, spring 19 is arranged outside the push rod between support 18 and flange, the push rod upper end can contact with the lifting travel switch 15 that is installed in the casing side, when revolve tapered end 20 insert freight containers hang the hole time, push rod is risen, open travel switch 15, can under spring 19 effects, push rod be resetted again then.

Fig. 5 is the sub-frame-sub-mantel view after omitting post rod mechanism among Fig. 3 and lifting by crane travel switch 15.Fig. 3 is the C-C view behind the omission handling travel switch 23 among Fig. 5.Handling travel switch 23 is installed in the side of

casing

11, and 24 among Fig. 6 is block.

During work, the driver starts wheeling mechanism and traveling mechanism of the larger traveller by electric control system in the driver's cab of hoisting crane, make dolly and whole hoisting crane run to the container position that will lift, and make container spreader be positioned at the freight container top, start lifting mechanism then, suspender is dropped to above the freight container, pass through guide piece, make S. A. insert hanging in the hole of freight container, push rod makes the action of lifting travel switch simultaneously, starts pushing mechanism then, allows fork drive and revolves the lock shaft rotation, at this moment, safety catch makes the action of handling travel switch.Starting lifting mechanism immediately makes freight container rise to certain altitude.And the lifting travel switch resets under the effect of spring, starts wheeling mechanism and traveling mechanism of the larger traveller afterwards, container crane to needed position.

Then, start lifting mechanism and big wheeling mechanism, put down freight container, push rod makes the action of lifting travel switch, starts pushing mechanism immediately, fork is driven revolve the lock shaft contrarotation, afterwards, start lifting mechanism, the suspender that hoists makes it break away from freight container, simultaneously, lifting travel switch and handling travel switch reset, and so far, have finished a working cycle process of handling freight container.
