[0016] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] As shown in the accompanying drawings, the utility model is a palletized transport device for cutting materials from marine modules, including a movable base 5. The movable base 5 can be the chassis of the entire device. A front support 4 and a rear support 6 are relatively connected to the front and rear sides of the movable base 5, and a movable limiting column 7 and a limiting column 1 are relatively arranged on the left and right sides of the movable base 5. A lifting structure 3 is fixed on the movable base 5 between the movable limiting column 7 and the limiting column 1. The front support 4 and the limiting column 1 are respectively fixedly connected to the movable base 5, and the rear support 6 is connected to the movable base 5 in a front-to-back sliding manner via a sliding structure, and the movable limiting column 7 is connected to the movable base 5 in a left-to-right sliding manner via a sliding structure. The front support 4 and the rear support 6 are respectively located on the front and rear sides between the limiting column 1 and the movable limiting column 7.

[0018] The sliding structure includes screw guide rail mounting grooves (left and right screw guide rail mounting grooves 5-1 corresponding to the position of the movable limiting column 7 and the rear support 6 in the figure) respectively, and the screw guide rail mounting grooves are installed in the screw guide rail mounting grooves. The screw guide rail is connected to the rotating shaft of the screw guide rail motor 5-3 (5-5) and is driven to rotate by the screw guide rail motor 5-3 (5-5). The screw guide rail motor 5-3 (5-5) is fixed to the movable base 5. Nuts are respectively installed at the bottom of the movable limiting column 7 and the rear support 6. The nuts and the screw are connected by a screw nut pair. The movable limiting column 7 can be driven by the driving motor to move left and right, thereby completing the limiting process of pallets of different sizes. The rear support 6 is driven by the driving motor to move forward and backward, thereby completing the advancement process and limiting process of the pallet. The sliding structure may also be a linear motor structure, or a propulsion structure such as a cylinder.

[0019] The limiting column 1 and movable limiting column 7 each include limiting column base plates 1-3 spaced horizontally in an upper and lower arrangement and tray supports 1-5, which provide support for the tray's advancement. The limiting column base plates 1-3 are fixed to the movable base 5, while the movable limiting column base plate 7 is slidably connected to the movable base via the sliding structure. The bottom plate and tray support of the limiting column near the right side of the front support 4 and the bottom plate and tray support of the movable limiting column are respectively fixedly connected to the lower part of the limiting column outer frame 1-1. The limiting column outer frame 1-1 is a ladder-shaped structure, and the limiting buckle 1-2 is rotatably connected to the limiting column outer frame 1-1 located above the tray support 1-5, and the limiting structure 1-4 is connected to the limiting column outer frame 1-1. The limiting buckle 1-2 can be rotated upward from a horizontal position under the action of the limiting structure until it is rotated into the inside of the limiting column outer frame to ensure that the pallet can pass upward. The limiting structure 1-4 can prevent the limiting buckle 1-2 from rotating downward. After the pallet passes a certain distance upward, the limiting buckle 1-2 rotates downward under the action of gravity until it contacts the limiting structure 1-4 and remains in a horizontal position and can be used to support the bottom surface of the stackable pallet, thereby realizing the unidirectional upward movement of the stackable pallet 2.

[0020] The stackable tray 2 includes a tray base 2-3, on which a positioning connection structure is provided. Among the stackable trays stacked up and down, the stackable tray located at the bottom can be connected up and down with the stackable tray located at the top through the positioning connection structure.

[0021] As an embodiment of the present invention, the positioning and connecting structure includes connecting columns 2-1 respectively arranged at the four corners of the tray base 2-3 in the vertical direction, and a cylindrical protrusion is provided on the top wall of each connecting column 2-1. A connecting hole is respectively opened at a position corresponding to the connecting column on the bottom surface of each tray base. The cylindrical protrusion on the lower stackable tray in the stackable trays stacked up and down can be inserted into the connecting hole setting on the upper stackable tray to realize the upper and lower connection of the trays.

[0022] Preferably, a pallet guardrail 2-2 is welded between two adjacent connecting columns 2-1, which can increase the loading capacity of the pallet and realize the loading of special materials such as pipelines.

[0023] The left and right ends of the bottom wall of the stackable tray 2 are respectively supported on the tray support 1-5 of the limiting column 1 and the tray support 1-5 of the movable limiting column 7, and can move along the tray support 1-5 under the push of the rear support 6 until it contacts the front support 4 for limitation.

[0024] The rear support 6 and front support 4 can include a base plate connected to a movable base 5. Two right-angled triangular supports are fixed to the base plate at intervals on the left and right sides. A connecting pillar is connected between the two right-angled triangular supports, which mainly provide position limiting and support functions. The base plate of the rear support 6 is connected to the movable base 5 via a sliding structure, and the base plate of the front support 4 is fixedly connected to the movable base 5.

[0025] The vertical motion output end of the lifting structure 3 is fixedly connected to a support plate arranged in the horizontal direction. Driven by the lifting structure, the support plate can be supported on the bottom surface of the stackable tray 2 at the lower end, thereby realizing the lifting process of the stackable tray 2. The lifting structure preferably adopts a linear electric push rod, but of course, a cylinder or other structure can also be used.

[0026] The working process of this device is as follows:

[0027] First, according to the actual size of the pallet, the distance between the limiting column 1 and the movable limiting column 7 is adjusted by the left and right screw guide rails 5-1 on the movable base 5 so that it can just accommodate the stackable pallet 2. Then, the stackable pallet 2 is placed behind the pallet support 1-5 between the limiting column 1 and the movable limiting column 7. Then, the front and rear screw guide motors 5-5 are activated to drive the rear support 6 to move forward and backward, thereby pushing the stackable pallet 2 to move. When the stackable pallet 2 contacts the front support 4, the rear support 6 is controlled to stop moving by the front and rear screw guide motors 5-5. Then, the lifting structure 3 is activated to lift the stackable pallet 2 to a certain height. At the same time, it is aligned with the other stackable pallets 2 through the structural connecting column 2-1 through the limiting buckle 1-2. Then, the lifting structure 3 is retracted, and the stacked stackable pallets 2 move downward as a whole. Due to the obstruction of the limiting structure 1-4, the limiting buckle 1-2 is in a horizontal position and can accommodate the stackable pallet 2 moving downward as a whole. The rear support 6 is then controlled by the forward and backward guide motor 5-5 to move in the opposite direction, completing one stacking task. When the last stacking task is completed, the rear support 6 is controlled by the forward and backward guide motor 5-5 to clamp the stacked pallets, maintaining the support state of the stackable pallet 2. The movable base 5 can then transport the stacked pallets 2 to the destination, and then release the clamping state to remove the stacked pallets from the left and right gaps of the front support 4 of the front section of the device using a forklift or other tool.
