The working principle of the utility model is as follows:

according to the research, the shaking of the shore bridge spreader is periodic, and swings like a sine function, and if the swinging period of the spreader is destroyed, the amplitude of the swinging can be rapidly attenuated to zero. The sling anti-swing system reduces the swing amplitude of the sling in a mode of destroying the swing cycle of the sling, thereby realizing the anti-swing function of the sling.

The anti-swing system 5 on the double-vehicle anti-swing crossing type shore bridge convenient for box alignment consists of a first anti-swing device 29, a second anti-swing device 30 and a third anti-swing device 31. The first anti-swing device 29 is used for preventing the sling from swinging in the direction of the shore bridge cart, and the second anti-swing device 30 and the third anti-swing device 31 are simultaneously used for preventing the sling from swinging in the direction of the shore bridge cart.

In the first anti-sway device 29, the first rope segment from the steel wire rope wound on the first reel 32 is turned by the first turning pulley block 33 and then connected to one side of the sling 35, the tail rope segment is turned by the first turning pulley block 33 and then connected to the other side of the sling 35, and the first rope segment and the tail rope segment of the steel wire rope wound on the first reel 32 are turned and then connected to the sling 35 in a cross structure. When hoist 35 takes place to rock in the cart direction, second motor 34 rotates towards corresponding direction, drives the first reel 32 that is connected with second motor 34 to the wire rope of winding on first reel 32 then can drag hoist 35, and then destroys the period of swaying of hoist 35, realizes the purpose of anti-rolling. In the second anti-roll apparatus 30, the third motor 36 drives the second winding drum 38 and the third winding drum 39, so as to adjust the tension of the wire rope 14 wound on the second winding drum 38 and the third winding drum 39, and the third motor 36 controls the pitch angle of the rocker arm apparatus 41, so as to control the opening angle between the wire rope 14 wound on the second winding drum 38 and the third winding drum 39, so as to adjust the horizontal component force. In the third anti-sway device 31, two fourth motors 36 are symmetrically distributed on two sides of the shore bridge trolley, and the two fourth motors 36 are connected through a coupler 42, so as to ensure synchronous operation between the two fourth motors 36. The first segment of the steel wire rope wound on the fourth drum 43 is turned by the third turning pulley block 45 and the C pulley 49 at one end of the first rocker arm 50, and then is connected with the lifting appliance 35, and the tail segment of the steel wire rope wound on the fourth drum 43 is turned by the third turning pulley block 45 and the C pulley 27 at the tail end of the second rocker arm 51, and then is connected with the lifting appliance 31. The rocker arm means 41 and the third rocker prevention means 31 co-operate so as to achieve a roll reduction of the spreader 35 in the direction of movement of the trolley.

The container of the utility model is operated by the following steps: when the quay crane lifts the container from the ship to load and unload the container onto and from the container truck, the container truck comes to a specified lane, the aligning device 4 also moves above the lane on which the container truck is parked, and the hollow aligning area is placed above the container truck. When the spreader 35 hangs a container and approaches the container aligning device 4, the container first collides with the guide position limiting device 14, most of the impact energy of the container is absorbed by the cushion layer 23 arranged on the guide plate 22, then the container enters the hollow aligning area 21 along with the inclination angle of the guide plate 22, so that the container is aligned with the position of the container truck, the spreader 35 continues to descend with the container, finally, the spreader 35 also descends through the hollow aligning area 21, when the spreader 35 descends until the end parts of the two sides of the spreader 35 contact with the baffle plates 26 of the telescopic device 15, and as the spreader 35 continues to descend, the telescopic frame body 25 of the telescopic device 15 is carried out to extend along with the spreader 35. Because of the telescopic device 15, the container is restricted in the running direction of the box device 4, no shaking occurs, and the shaking in the running direction of the cart is greatly reduced because of the friction generated by the contact between the spreader 35 and the baffle 26. Therefore, the container and the container truck can be aligned quickly and accurately, and the efficiency of aligning the containers is greatly improved. After the completion of the pair of boxes, the spreader 35 is retracted, the first electrode 13 controls the telescopic device 15, and the telescopic frame body 25 is retracted.
