Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of loading and unloading equipment, in particular to a shore crane loading and unloading system. BACKGROUND

[0002] As the most important container loading and unloading equipment in the port, the shore crane undertakes the loading and unloading work of most container ships in the port, so the working efficiency of the shore crane directly affects the loading and unloading efficiency of the container ships in the port.

[0003] In the operation process of the shore crane, the trolley of the shore crane moves along the girder, the spreader is pulled on the trolley of the shore crane by the wire rope, the lifting of the spreader is controlled by the lengthening or shortening of the wire rope, so as to lift or drop the container, and then the container is transported between the container truck and the container ship by moving the trolley of the shore crane. Since the stacking height of the containers on the sea side of the container ship is often much higher than that of the container truck on the road side, the distance of the wire rope needs to be lengthened or shortened during the container transportation operation, which consumes a lot of time for the container lifting operation; and the spreader often shakes easily, and the load platform on the container truck is comparable in width to the container, which makes it difficult for the spreader to quickly align the container with the load platform on the container truck, so a lot of time is consumed for the container aligning operation, which ultimately leads to low efficiency of the shore crane in loading and unloading containers.

Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall into the protection scope of the present application.

[0036] The embodiments of the present application are described below with reference to the drawings. Figures 1-3

[0037] According to the embodiments of the present application, a shore crane loading and unloading system is provided, as shown in Figure 1 Fig. 1, which comprises a container shore crane 1, a transfer platform 2 and a lifting mechanism 3.

[0038] The container shore crane 1 has a girder 101 and a shore crane trolley 102 adapted to move along the girder 101, and the shore crane trolley 102 is provided with a first lifting appliance 103 which can be raised or lowered and is adapted to hoist a container 100; the transfer platform 2 is located below the girder 101 and is adapted to transfer the container 100; the lifting mechanism 3 is arranged on at least one side of the transfer platform 2 and comprises a second lifting appliance 301 which can be raised or lowered and is adapted to hoist the container 100; wherein the first lifting appliance 103 is adapted to hoist the container 100 on a transport ship on the sea side and drop it to the transfer platform 2 for transfer, and the second lifting appliance 301 is adapted to hoist the container 100 on the transport vehicle 4 on the land side and drop it to the transfer platform 2 for transfer, and the first lifting appliance 103 is adapted to hoist the container 100 lifted to the transfer platform 2 and drop it to the transport ship on the sea side; and the second lifting appliance 301 is adapted to hoist the container 100 on the transport vehicle 4 on the land side and lift it to the transfer platform 2 for transfer, and the first lifting appliance 103 is adapted to hoist the container 100 lifted to the transport ship on the sea side.

[0039] ​In the above embodiment, by setting the transfer platform 2 and the lifting mechanism 3, the first hoist 103 of the container shore crane 1 hoists the container 100 between the sea side transport ship and the transfer platform 2 located below the girder 101, the transfer platform 2 transfers the container 100, and the second hoist 301 of the lifting mechanism 3 hoists the container 100 between the transfer platform 2 and the land side transport vehicle 4; the two groups of hoists can operate respectively, reducing the time consumption of the container hoisting operation; the distance of the second hoist 301 lowered to the land side transport vehicle 4 is much smaller than the distance of the first hoist 103 directly lowered to the land side transport vehicle 4, which can effectively reduce the shaking of the second hoist 301 and reduce the time consumption of the container handling operation between the second hoist 301 and the land side transport vehicle 4; the time consumption is reduced in container hoisting and container handling, thereby improving the efficiency of the shore crane in loading and unloading containers.

[0040] Specifically, the container shore crane 1 and the lifting mechanism 3 can independently operate, and after the first hoist 103 hoists the container 100 to the transfer platform 2, it can leave for the next operation, and similarly, after the second hoist 301 hoists the container 100 to the transfer platform 2, it can leave for the next operation, the two hoisting and transferring modes do not affect each other and reasonably divide the work, which helps to improve the efficiency of the shore crane in loading and unloading containers.

[0048] Specifically, as shown in Figure 1 The two turnover platforms 202 are rotationally connected with the main platform 201 on two sides thereof by two rotation shafts 203 respectively, and can be rotationally controlled by a controller.

[0049] In some embodiments, asFigure 1 As shown, as a preferred embodiment, the main platform 201 and the turnover platform 202 are respectively provided with a conveyor belt, which is suitable for transferring the container 100.

[0050] In the above embodiment, the conveyor belt is arranged on the main platform 201 and the turnover platform 202 respectively, so that the transfer operation of the container 100 is realized by the conveyor belt, which is simple in structure and efficient.

[0051] Specifically, as shown in the drawings, Figure 1 The width of the main platform 201 and the width of the turnover platform 202 are both equivalent to the length of the container 100, and the main platform 201 is respectively provided with an independently operated conveyor belt on each turnover platform 202, and the three groups of conveyor belts are operated according to the instructions of the scheduling system, so as to transfer the container 100 on the main platform 201 to the appropriate turnover platform 202, and then cooperate with the first hoist 103 or the second hoist 301 to perform the next hoisting operation.

[0054] In the above embodiment, the driving device 302 outputs power to drive the traction rope 303 to move up and down, and drives the second hoist 301 to move up and down, so as to realize the hoisting operation of the second hoist 301 on the container 100.

[0055] Specifically, as shown in the drawings, Figure 1 The driving device 302 is set as a winch, and the traction rope 303 is set as a steel wire rope or a steel cable.

[0059] In the above embodiment, the traction rope 303 is connected with the second lifting appliance 301 through the mounting bracket 305, and the mounting bracket 305 is guided in the vertical direction by the guide rail 304, so as to ensure the stability of the second lifting appliance 301 running in the vertical direction; since the guide rail 304 guides the mounting bracket 305 and also guides the second lifting appliance 301, the shaking of the traction rope 303 driving the second lifting appliance 301 is limited, so as to effectively avoid the shaking of the second lifting appliance 301; at this time, the second lifting appliance 301 and the transport vehicle 4 are fixed structure to fixed structure, and the difficulty of the box operation between the two is greatly reduced, the time consumption of the box operation between the second lifting appliance 301 and the transport vehicle 4 is reduced, and the efficiency of the shore crane loading and unloading the container is further improved.

[0060] Specifically, as shown in Figure 1 , the guide rail 304 is arranged on both sides of the transfer platform 2 and is guided and connected with the mounting bracket 305 on the lifting mechanism 3 on both sides of the transfer platform 2.

[0073] In the above embodiment, the main structure 104 of the container quay crane 1 is used as the installation base of the transfer platform 2 and the lifting mechanism 3, which improves the integrity of the quay crane loading and unloading system.

[0074] Specifically, as shown in Figure 1 The main structure 104 of the container quay crane 1 provides an installation position for the transfer platform 2 and the lifting mechanism 3, so that the main platform 201 on the transfer platform 2 and the guide rail 304 in the lifting mechanism 3 are directly fixedly connected to the main structure 104 of the container quay crane 1.

[0075] Further, as shown in Figure 1 The second spreader 301 is vertically slidably arranged on the guide rail 304 through the several frames of the lifting mechanism 3, and since the guide rail 304 is relatively fixed relative to the door leg of the main structure 104 of the container quay crane 1, the sliding of the second spreader 301 in the vertical direction is relatively fixed, which can prevent the container 100 from shaking during the container handling process.

[0076] Further, as shown in Figure 1 The driving device 302 in the lifting mechanism 3 is directly fixedly connected to the girder 101 of the container quay crane 1.

[0077] The working mode of the quay crane loading and unloading system provided in the embodiment is as follows:

[0078] When the container 100 is loaded from the sea side container ship to the road side transport vehicle 4, the first spreader 103 of the container quay crane 1 lifts the container 100 on the sea side container ship, and through the wire rope zooming and the quay crane trolley moving, the container 100 is lifted and placed on the main platform 201 of the transfer platform 2. After the container 100 is transferred to the turnover platform 202 on one side of the main platform 201 by the conveyor belt, the second spreader 301 of the lifting mechanism 3 lifts the container 100, the turnover platform 202 is turned to a position perpendicular to the main platform 201 to avoid the second spreader 301 and the container 100 lifted thereby, so that the second spreader 301 can continue to fall along the guide rail 304 to approach the land side transport vehicle 4. The position of the second spreader 301 and the container 100 lifted thereby is fine adjusted by using the movable frame 3053 of the installation bracket 305 in the lifting mechanism 3, and after adjustment, the second spreader 301 lowers the container 100, so that the container 100 is loaded on the road side transport vehicle 4.

[0079] When the container 100 is loaded from the road side transport vehicle 4 to the sea side container ship, the transport vehicle 4 carrying the container 100 drives to the side of the guide rail 304 of the lifting mechanism 3, i.e. below the second spreader 301, the position of the second spreader 301 is finely adjusted by the movable frame body 3053 of the support 305 in the lifting mechanism 3, after adjustment, the second spreader 301 hoists the container 100, the turnover platform 202 is turned over to the vertical position of the main platform 201 to avoid the second spreader 301 and the container 100 hoisted by the second spreader 301, when the second spreader 301 and the container 100 hoisted by the second spreader 301 are lifted to the relative height of the main platform 201 of the transfer platform 2, the turnover platform 202 is reset, the second spreader 301 drops the container 100 to the turnover platform 202 and transfers the container 100 to the main platform 201 by the turnover platform 202, the first spreader 103 of the container quay crane 1 hoists the container 100, and the container 100 is loaded into the sea side container ship by the steel wire rope retraction and the movement of the quay crane trolley.

[0080] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
