Further, as shown in fig. 1, the second lifting appliance 301 is vertically slidably disposed on the guide rail 304 through a plurality of frames of the lifting mechanism 3, and since the guide rail 304 is relatively fixed with respect to the door leg of the main structure 104 in the container shore bridge 1, the sliding of the second lifting appliance 301 in the vertical direction is relatively fixed, so that the container 100 in the process of shaking can be prevented.
Further, as shown in fig. 1, the driving device 302 in the lifting mechanism 3 is directly fixedly connected to the girder 101 of the container shore bridge 1.
The operation mode of the quay crane loading and unloading system provided by the embodiment is as follows:
When the container 100 is loaded on the transport vehicle 4 on the road side from the container ship on the sea side, the first lifting appliance 103 of the container shore bridge 1 lifts the container 100 on the container ship on the sea side, the container 100 is lifted to the main platform 201 of the transfer platform 2 and placed by the length-enlarging of the steel wire rope and the movement of the shore bridge trolley, the conveying belt transfers the container 100 to the overturning platform 202 on the side of the main platform 201, the second lifting appliance 301 of the lifting mechanism 3 lifts the container 100, the overturning platform 202 is overturned to the position vertical to the main platform 201 so as to avoid the second lifting appliance 301 and the lifted container 100, the second lifting appliance 301 can continuously fall down the transport vehicle 4 near the land side along the guide rail 304, the second lifting appliance 301 and the position of the lifted container 100 are finely adjusted by the movable frame 3053 of the mounting bracket 305 in the lifting mechanism 3, and the second lifting appliance 301 drops the container 100 after being adjusted in place, so that the container 100 is loaded on the transport vehicle 4 on the road side.
When the container 100 is loaded into a sea-side container ship from the road-side transport vehicle 4, the transport vehicle 4 loads the container 100, the container 100 runs to one side of the guide rail 304 of the lifting mechanism 3, namely, the lower part of the second lifting tool 301, the position of the second lifting tool 301 is finely adjusted by utilizing the movable frame 3053 of the mounting bracket 305 in the lifting mechanism 3, the container 100 is lifted by the second lifting tool 301 after the adjustment is in place, the overturning platform 202 is overturned to a position perpendicular to the main platform 201 so as to avoid the second lifting tool 301 and the container 100 lifted by the second lifting tool 301, when the second lifting tool 301 and the container 100 lifted by the overturning platform 202 are lifted to be above the relative height of the main platform 201 of the transit platform 2, the second lifting tool 301 drops the container 100 to the overturning platform 202 and is transferred to the main platform 201 by the overturning platform 202, the container 100 is lifted by the first lifting tool 103 of the container shore bridge 1, and the container 100 is loaded into the sea-side container ship by retracting a steel wire rope and the shore bridge trolley.
Although embodiments of the present invention have been described in connection with the accompanying drawings, various modifications and variations may be made by those skilled in the art without departing from the spirit and scope of the invention, and such modifications and variations fall within the scope of the invention as defined by the appended claims.
