Specifically:

[0024] The walking mechanism includes walking wheels 4 installed on the bottom beam 1 and a walking drive mechanism 5 for driving the walking wheels 4 to rotate. The number of the walking mechanisms is two sets, and two groups of walking wheels 4 are provided in any one set of walking mechanisms. The two sets of walking mechanisms are respectively arranged at the front and rear ends of the bottom beam 1, that is, a set of walking mechanisms is respectively arranged at the front and rear ends of the bottom beam 1, and the two groups of walking wheels 4 of the same set of walking mechanisms are respectively arranged on the left and right sides of the bottom beam 1, that is, a group of walking wheels is respectively arranged on the left and right sides of the front and rear ends of the bottom beam 1, and a total of four groups of walking wheels are provided. Each group of walking wheels 4 is provided with 5 walking wheels 4, of which 2 walking wheels 4 are set as driving wheels, 2 walking wheels 4 are set as passive wheels, and the remaining 1 walking wheel 4 is set as a follower wheel;

[0025] The travel drive mechanism 5 includes a travel drive motor, which is connected to the travel wheel 4 through a sprocket chain transmission structure. Specifically, a sprocket is mounted on the wheel axle of the travel drive motor and the travel wheel 4 as the driving wheel. The sprocket is driven by the chain, so that the travel drive motor drives the travel wheel 4 as the driving wheel to rotate, thereby realizing the walking action of the bottom beam 1;

[0026] The lifting mechanism includes a lifting trolley 6, vertical guide rails 7 mounted on the columns 2, and a lifting power mechanism 8 for driving the lifting trolley 6 to move back and forth along the vertical guide rails 7. There are four vertical guide rails 7, each mounted on one of the four columns 2. The lifting trolley 6 includes a trolley base plate and trolley side plates mounted on the trolley base plate. Four guide shoes are mounted on the trolley side plates, which are respectively rolled onto the four vertical guide rails 7. The trolley base plate is welded from steel plates to support the weight of the dual telescopic mechanism and cargo. The trolley side plates are also welded from steel plates, with four guide shoes installed at the four corners of the trolley side plates, enabling the lifting trolley 6 to move up and down along the four guide rails.

[0027] The lifting mechanism 8 includes a lifting drive motor, which is connected to the lifting trolley 6 via a sprocket and chain transmission structure. The lifting drive motor 8 is fixedly mounted on the column 2. A sprocket is mounted on the motor shaft of the lifting drive motor. Two sets of sprockets are mounted on the upper beam 3 and driven by a chain. The lifting trolley 6 is fixedly connected to the chain, facilitating up and down movement under the drive of the lifting drive motor.

[0028] The double telescopic mechanism includes a base 9 mounted on the lifting pulley 6, and a double telescopic fork 10 is mounted on the base 9 via a double telescopic drive mechanism 11. The movement direction of the double telescopic fork 10 is perpendicular to the length direction of the column 2 and the length direction of the bottom beam 1. The base 9 can be mounted on the pulley bottom plate of the lifting pulley 6, and the double telescopic drive mechanism 11 can be mounted on the base 9 or the pulley side plate. The double telescopic drive mechanism 11 includes a double telescopic drive motor, which is connected to the double telescopic fork 10 through a gear rack transmission structure. The double telescopic fork 10 can be slidably mounted on the base 9 via a slider rail transmission structure. A rack is mounted on the double telescopic fork 10, and a gear that cooperates with the rack is mounted on the motor shaft of the double telescopic drive motor. This facilitates the use of the double telescopic drive motor to operate. Through the coordination of the gear rack, the double telescopic fork 10 can be telescopically moved left and right to meet the needs of loading and unloading.

[0029] The stacker also includes an upper guide rail 15 and a lower guide rail 16. The lower guide rail 16 is provided with two. An upper lateral wheel 13 rollingly arranged on the upper guide rail 15 is installed on the upper beam 3, and a lower lateral wheel 12 rollingly arranged on the lower guide rail 16 is installed on the bottom beam 1. The upper guide rail is composed of an 80×80mm square steel and is fixed to the upper beam of the ship at intervals of 1200mm. The lower rail is composed of two 80×60mm rectangular steels and is fixed to the ship deck at intervals of 1200mm.

[0030] The upper beam 3 is welded from 16mm thick steel plates into an I-shaped double-beam structure, with a pair of upper lateral pressure wheels 13 installed at each end. A rolling gap is left between the two upper lateral pressure wheels 13 at the same end of the upper beam 3 to cooperate with the upper guide rail 15, so that the upper part of the stacker can run along the track of the upper guide rail 15; the bottom beam 1 is welded from 16mm thick steel plates into a rectangular frame structure, with two lower lateral wheels 12 installed on both sides of the bottom beam 1, for a total of four lower lateral wheels 12. The two lower lateral wheels 12 on one side of the bottom beam 1 are rolled on one of the lower guide rails 16, and the two lower lateral wheels 12 on the other side of the bottom beam 1 are rolled on the other lower guide rail 16, ensuring that the stacker runs along the direction of the lower guide rail 16 and does not deviate from the side.

[0031] The main body of column 2 is made of 6mm thick cold-rolled steel plate cold-bent into an inner curled channel steel shape. Two connecting plates are welded at both ends of column 2 (which can be connected to upper beam 3 and bottom beam 1 respectively). Six frame guide rail base plate connecting frames are welded on the outer side of the web of column 2, and M12 threads are drilled and tapped. A lifting mechanism sprocket and axle seat plate are welded to the outside of the flange on one side of the lower part of column 2, and the guide rail base plate is connected and fixed to the connecting frame with hexagon socket bolts, and then the roller heavy-load linear guide is fixed to the connecting frame with bolts.

[0032] In actual use, the stacker also includes an anti-tilting safety protection device, which includes a lower hook plate 14 provided on the bottom beam 1 at the wheel axle of the running wheel 4. The lower part of the lower hook plate 14 extends below the upper plane of the lower guide rail 16. In the event that the running wheel 4 generates negative pressure, the lower hook plate 14 can hook the lower guide rail 16 to ensure that the running wheel 4 does not tilt, so that the stacker can withstand tilting and swaying environments.

[0033] The stacker also includes an anti-self-movement safety protection device, which includes locking pins inserted into the four corners of the bottom beam 1. When the stacker is not in operation, the locking pins are inserted to prevent the stacker from moving on its own so as to withstand the wind and wave environment of the ocean.

[0034] When in use, first assemble the stacker, specifically:

[0035] 1. Use bolts to connect the four columns 2 to the upper beam 3 and the bottom beam 1 respectively;

[0036] 2. Assemble two sets of walking mechanisms;

[0037] 3. Assemble the lifting mechanism;

[0040] 6. Install the double telescopic fork 10 on the bottom plate of the lifting pulley 6;

[0041] 7. Connect and install the double telescopic mechanism;

[0042] In this way, an improved double-extended marine stacker is formed;

[0043] Then carry out the operation, specifically as follows:

[0044] 1. Start the stacker;

[0045] 2. Travel operation:

[0046] According to the need, control the travel direction (forward or backward) of the stacker;

[0047] Use the travel mechanism to drive the stacker to move in the cargo hold or warehouse of the ship until it reaches the position of the target shelf;

[0048] 3. Lifting operation:

[0049] When the stacker reaches the position of the target shelf, adjust the height of the lifting mechanism, and use the lifting mechanism to lift or lower the lifting trolley 6 and the double telescopic fork 10 thereon to the layer of the target shelf;

[0050] When the lifting trolley 6 reaches the target layer, start the double telescopic mechanism. The double telescopic fork 10 first extends outwards until it reaches within the width range of the goods on the shelf, and then lifts upwards until it can lift the goods;

[0051] 4. Carry goods:

[0052] Use the lifting mechanism and the travel mechanism to carry the goods to the designated position;

[0053] After reaching the designated position, release the goods by adjusting the position of the double telescopic fork 10;

[0054] After confirming that the goods are placed stably, retract the double telescopic fork 10;

[0055] 5. Return to the original position:
