Description

Technical Field

[0001] This invention relates to the field of container loading and unloading technology, specifically a bidirectional pallet trolley container loading and unloading platform with anti-fork tilting features. Background Technology

[0002] A shipping container is a modular tool used to transport packaged or unpackaged goods, facilitating loading and unloading by mechanical equipment. The greatest success of the container lies in its standardization and the resulting comprehensive transportation system. The ability to standardize a massive container weighing tens of tons, and to gradually build a global logistics system integrating ships, ports, shipping routes, highways, transit stations, bridges, tunnels, and multimodal transport, is truly one of the greatest miracles of human history.

[0003] Currently, container loading and unloading operations require the use of lifting structures. However, in some indoor environments where it is inconvenient to use lifting structures, trailers are needed for transport. When encountering steps, a lifting structure is required to lift the container. However, single-arm support lifting structures cause the top surface to move during lifting, resulting in instability and deviation. Furthermore, the lack of an angle adjustment structure makes it unsuitable for current loading and unloading needs. Summary of the Invention

[0004] The purpose of this invention is to provide a bidirectional pallet trolley container loading and unloading platform with anti-fork tilting features, to solve the problems mentioned in the background art. Currently, container loading and unloading operations require the use of lifting structures. However, in some indoor environments where it is inconvenient to use lifting structures, trolleys are needed for transporting the containers. When encountering steps, a lifting structure is required for the vehicle body to be lifted. In single-arm support lifting structures, the top surface moves with the lifting, resulting in instability and deviation. Furthermore, the lack of an angle adjustment structure fails to meet the current loading and unloading requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A sleeve block is symmetrically sleeved on the outer side of the connecting rod. A lifting cylinder is connected to one end of the sleeve block. A fixing rod is inserted into the end of the lifting connecting rod away from the connecting shaft. Rotary cylinders are symmetrically bolted to both sides of the lifting middle plate. Cross connecting plates are joined to the sides of the lifting connecting rod. A fixing base block is symmetrically welded to the side of the supporting base plate away from the fixing side plate. A tilting cylinder is connected to one end of the fixing base block. A fixing block is symmetrically welded to the bottom surface of the tilting guide plate. An adjusting motor is bolted to the inner side of the lifting middle plate.

[0007] In a preferred embodiment of the present invention, the supporting base plate is frame-shaped, and there are multiple supporting side strips arranged in parallel with each other. The sides of the multiple supporting side strips are symmetrically provided with through holes near both ends.

[0008] In a preferred embodiment of the present invention, the pallet truck track consists of multiple tracks arranged in parallel to each other, and all tracks are horizontally positioned on the side between multiple support side strips. The side plates of the multiple pallet truck tracks have through holes near both ends.

[0009] In a preferred embodiment of the present invention: one side of the flipping guide plate is connected to one end of multiple pallet truck tracks by a hinge, and the top surface of the flipping guide plate and the top surface of the pallet truck tracks are kept at the same horizontal plane. There are two transmission shafts, which are arranged in parallel to each other. The two transmission shafts are horizontally inserted into the inner side of the through holes near both ends of the pallet truck tracks and the support side strips.

[0010] In a preferred embodiment of the present invention: there are multiple transmission chains, which are arranged in parallel with each other. Each of the multiple transmission chains is horizontally positioned near the side of the pallet truck track. The two ends of the multiple transmission chains are horizontally sleeved on the outer side of the transmission gear. There are two power motors, which are symmetrically fixed on one side of the fixed side plate near both ends.

[0011] In a preferred embodiment of the present invention: the top ends of the power chains all extend upward and are sleeved on the outer side of the corresponding transmission gears; the stabilizing base plate and the supporting base plate are arranged in parallel and superimposed arrangement; the lifting middle plate is horizontally arranged between the stabilizing base plate and the supporting base plate; and the three are arranged in parallel and superimposed arrangement. The fixed side plate is horizontally fixedly arranged on the bottom surface of the supporting base plate on the side away from the flipping guide plate.

[0012] In a preferred embodiment of the present invention: multiple sets of transmission gears are fixedly sleeved and parallel to each other on the outer side of the transmission shaft. The middle locking gear is horizontally locked in a ring shape at the center of the top surface of the lifting plate, and the top surface of the middle locking gear is fixedly connected to the bottom surface of the center connecting plate of the support base plate by bolts. The adjusting gear is horizontally positioned on the outer side of the middle locking gear, and the sides of the gears are toothed together. The center position of the adjusting gear is fixedly sleeved at the output end of the adjusting motor.

[0013] In a preferred embodiment of the present invention: there are four lifting links, and the four lifting links are symmetrically arranged in pairs on the inner side of the stable base plate. One end of the insert shaft is inserted into the inner side wall of the stable base plate near the center. There are two connecting rods, and the two connecting rods are arranged parallel and symmetrically on the inner side of the stable base plate. The output end of the lifting cylinder extends and is connected to the outer side wall of the shaft at one end of the cross connecting plate. The rotary cylinder is vertically fixed at the corners of both sides of the lifting middle plate, and its output end is connected to the outer side of the fixed insert rod.

[0014] In a preferred embodiment of the present invention: the number of the cross connecting plates is set to be consistent with the number of the lifting connecting rods, and they are connected by the rods to form an X-shaped cross arrangement. The fixed base block is fixedly set on the bottom surface of the support base plate near the two corners. The output end of the flipping cylinder is connected to the bottom end of the fixed block by the insertion rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention involves placing a container on top of a pallet truck after a stable base plate is horizontally fixed in a designated position. One end of the pallet truck's bottom is engaged with the side groove of the pallet truck track. The extension or retraction of a tilting cylinder causes a fixed block to move, thereby causing the top tilting guide plate to tilt to a designated angle at one end of the pallet truck track, providing support and lifting for the pallet truck. After the container is loaded onto the pallet truck, the upward tilting of the tilting guide plate is controlled while the power motor rotates, causing the main gear to drive the transmission chain. This, in turn, causes the transmission gear to drive the transmission shaft to rotate, and the horizontal transmission of multiple transmission chains pulls the pallet truck towards the top of the pallet truck track. With the assistance of the tilting guide plate, the pallet truck can be moved more quickly to the top of the pallet truck track and placed horizontally.

[0017] 2. This invention, through the controlled extension operation of the rotary cylinder and the lifting cylinder, enables the output end to connect to the cross plate and lifting rod for cross-lifting processing, raising the lifting plate connected at the top to a specified height. Simultaneously, the control operation of the adjusting motor causes the rotation of the adjusting gear, which in turn causes the middle locking gear to rotate to a specified angle on the top surface of the lifting plate. This, in turn, causes the top support plate to rotate together with the pallet cart to a specified angle to meet the loading and unloading operation. The cross-lifting structure makes lifting faster and more efficient, and the cross-connection lifting structure makes lifting more stable and prevents deviation. Furthermore, the combination of pallet cart and track structure for loading and unloading materials greatly accelerates the loading and unloading efficiency. Attached Figure Description

[0031] All components are general standard parts or components known to those skilled in the art, and their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0032] The working principle of this invention is:

[0033] After the stable base plate 10 is horizontally fixed in the designated position, the container is placed on top of the pallet truck. One end of the pallet truck's bottom is engaged with the side groove of the pallet truck track 3.

Under the control of the extension operation of the rotary cylinder 22 and the lifting cylinder 20, the output end is connected to the cross plate 23 and the lifting rod 16 for cross lifting. The lifting plate 11 connected at the top is raised to the specified height. At the same time, under the control of the adjusting motor 27, the rotation drives the adjusting gear 15 to rotate. The rotation of the adjusting gear 15 drives the middle locking gear 14 to rotate to the specified angle on the top surface of the lifting plate 11. The top support plate 1 drives the pallet truck to rotate to the specified angle to meet the loading and unloading operation.
