[0035] Specifically, in the embodiment of the utility model, the outer extension fixed pulley set 5 includes: first outer extension fixed pulley 501, second outer extension fixed pulley 502, third outer extension fixed pulley 503, fourth outer extension fixed pulley 504, the first outer extension fixed pulley 501 with the first movable pulley 401 is connected through the wire rope corresponding, the second outer extension fixed pulley 502 with the second movable pulley 402 is connected through the wire rope corresponding, the third outer extension fixed pulley 503 with the third movable pulley 403 is connected through the wire rope corresponding, the fourth outer extension fixed pulley 504 with the fourth movable pulley 404 is connected through the wire rope corresponding, wherein, the first outer extension fixed pulley 501 with the first movable pulley 401, the fourth outer extension fixed pulley 504 with the fourth movable pulley 404 are located in the same working plane, the second outer extension fixed pulley 502 with the second movable pulley 402, the third outer extension fixed pulley 503 with the third movable pulley 403 are located in the same working plane.

[0041] Specifically, in the embodiment of the utility model, the reel mechanism set 3 includes: a first reel mechanism 301, a second reel mechanism 302; the steel wire rope set 8 includes: a first steel wire rope 801, a second steel wire rope 802, a third steel wire rope 803, a fourth steel wire rope 804; the first reel mechanism 301 winds the first steel wire rope 801 and the fourth steel wire rope 804; the second reel mechanism 302 winds the second steel wire rope 802 and the third steel wire rope 803; after the first steel wire rope 801 extends from the first reel mechanism 301, it is connected to the first fixed seat 701 in turn through the first extension fixed pulley 501, the first movable pulley 401 and the first reversing fixed pulley set 601; after the second steel wire rope 802 extends from the second reel mechanism 302, it is connected to the first fixed seat 701 in turn through the second extension fixed pulley 502, the second movable pulley 402 and the second reversing fixed pulley set 602; after the third steel wire rope 803 extends from the second reel mechanism 302, it is connected to the second fixed seat 702 in turn through the third extension fixed pulley 503, the third movable pulley 403 and the third reversing fixed pulley set 603; after the fourth steel wire rope 804 extends from the first reel mechanism 301, it is connected to the second fixed seat 702 in turn through the fourth extension fixed pulley 504, the fourth movable pulley 404 and the fourth reversing fixed pulley set 604.

[0042] More specifically, it needs to be explained that during the transportation of containers, whether it is loading or loading, it needs to be lifted by a crane, and for the convenience of lifting, a special container sling is often used, but the traditional lifting mechanism is perpendicular to the angle of the wire rope and the sling, and does not form a cable-stayed in the transverse and longitudinal directions of the sling, so there is no horizontal component force to constrain the horizontal direction of the sling swing, so that the container sling is prone to sway during the operation of the crane, which makes it difficult to dock the container sling with the container, and the operator needs to move the container sling to the vicinity of the container first, then wait for the container to be lifted The sling is stationary, and then further operation of the container sling and the container is connected, which seriously affects the efficiency of lifting. Although the prior art has provided a bidirectional anti-sway lifting mechanism, the anti-sway mechanism includes a movable pulley fixed on the sling, a winding drum, a guide fixed pulley and a reversing pulley fixed on the trolley frame; the two movable pulleys in the same longitudinal direction are inward on the opposite side and outward on the opposite side, and the two movable pulleys are arranged in the same longitudinal direction. The wire rope is wound out from the winding drum, passes through the outward side of the movable pulley on the sling, is introduced from the inward side of the movable pulley on the sling, and is connected with the sling after passing through the guide fixed pulley and the reversing pulley on the other outward side, but in this technical solution, the first wire rope segment is directly wound into the movable pulley on the sling from the winding drum, so the angle of the cable-stayed in the trolley direction is relatively small, and the second wire segment is a wire rope that is wound out from the inward side of the movable pulley on the sling. The guide fixed pulley on the other outward side, so the two wire ropes in the same longitudinal side of the trolley direction will have a cross region, and the prior art arranges the two movable pulleys in the same longitudinal direction, so that the horizontal component force of the two wire ropes is not on the same straight line, which may still cause the sling to sway.

[0043] Based on the deficiencies in the prior art, the first wire segment of the steel wire rope is wound out from the winding drum, passes through the fixed pulley fixed on the trolley frame, so that the second wire segment is wound out from the fixed pulley and passes through the outward side of the movable pulley on the sling, so that the angle of the cable-stayed in the trolley direction is larger; the third wire segment is wound out from the inward side of the movable pulley on the sling and passes through the steel wire rope guide device in the same outward direction of the movable pulley, so that the two wire ropes in the same longitudinal side of the trolley direction do not have a cross region, and the two movable pulleys in the same longitudinal direction do not need to be arranged. The wire rope winding group is arranged by the fixed pulley and the steel wire rope guide device, so that the first wire segment on the steel wire rope in the wire rope winding group increases the angle of the cable-stayed, and the remaining three wire segments are all cable-stayed segments, wherein the second and third wire segments are longitudinal cable-stayed segments, and the fourth wire segment is a transverse cable-stayed segment. Further, the cooperation of the three cable-stayed segments realizes the anti-sway of the sling in the transverse or longitudinal direction. Since there is no intersection between different steel wire ropes in the longitudinal and transverse directions, the interference problem between different steel wire ropes does not need to be considered. In summary, the technical scheme related to the embodiments of the present utility model has the following technical effects:

[0044] After the steel wire rope is wound out from the reel, it firstly passes through the fixed pulley fixed on the trolley frame, and then is wound out from the outside of the movable pulley on the lifting appliance, so that the angle of the trolley direction is large, the horizontal component force is increased, and the swing of the lifting appliance in the horizontal direction is restrained.

[0045] The third rope section is wound out from the inside of the movable pulley on the lifting appliance, and then passes through the steel wire rope guide device in the same outside direction of the movable pulley, instead of passing through the guide fixed pulley on the other outside as in the prior art. Such a design can avoid the intersection area of the two steel wire ropes in the trolley direction of the same longitudinal side, simplify the structure, and reduce the interference problem.

[0046] Without staggering the movable pulleys, since the intersection of the steel wire ropes is avoided, the two movable pulleys in the same longitudinal direction also do not need to be staggered, which not only simplifies the design of the lifting appliance mechanism, but also makes the horizontal component force on the steel wire rope more easily in the same straight line, further reducing the swing of the lifting appliance.

[0047] Moreover, the steel wire rope winding group forms three inclined rope sections through the setting of the fixed pulley and the steel wire rope guide device, that is, the second and third rope sections are longitudinal inclined rope sections, and the fourth rope section is a transverse inclined rope section, so that the three inclined rope sections cooperate with each other to more effectively realize the roll damping of the lifting appliance frame in the transverse direction or the longitudinal direction.

[0048] In addition, since the swing of the lifting appliance is reduced, the operator can more easily dock the container lifting appliance with the container without waiting for the lifting appliance to be stationary, which greatly improves the lifting efficiency and shortens the operation time. Compared with the prior art, the crane bidirectional roll damping hoisting mechanism provided by the embodiment of the utility model can overcome the above technical problems, overcome the swing problem of the container lifting appliance during the crane operation, obviously improve the lifting efficiency, and has a significant technical effect.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model.
