[0033] Embodiment

[0034] Referring to Figure 1 - Figure 10 , a forklift frame for port cargo transportation, this device includes: a forklift unit 100, a frame unit 200, and a clamping unit 300.

[0035] Among them, the forklift unit 100 includes a forklift body 101, and a connecting part 102 is fixedly connected to the top of the forklift body 101. When transporting cylindrical objects such as gasoline barrels at the port, the operator drives the forklift body 101 to the designated position of the goods, and carries out the cargo transportation work through the connecting part 102 and the frame unit 200;

[0036] The frame unit 200 includes a lifting assembly 201 on the connecting part 102, a driving assembly 202 arranged on the lifting assembly 201, a linkage assembly 203 arranged on the driving assembly 202, a limiting block 204 arranged on the lifting assembly 201, and a limiting groove 205 arranged on the lifting assembly 201, and the limiting groove 205 is slidably connected with the limiting block 204. The clamping unit 300 includes a clamping assembly 301 arranged on the linkage assembly 203.

[0037] When transporting cylindrical or irregular-shaped goods at the port, the operator drives the forklift body 101 to the designated goods position, then uses the clamping assembly 301 to insert into the goods. After completing the clamping preparation work, the lifting assembly 201 is driven to extend and retract, so that the lifting assembly 201 starts to move upward with the driving assembly 202. At the same time, while the driving assembly 202 moves upward, the linkage assembly 203 also drives the clamping assembly 301 to move upward together, so that the clamping assembly 301 on the linkage assembly 203 starts to move from both sides towards the middle of the goods, thereby clamping and fixing the goods. At the same time, as the clamping assembly 301 approaches driven by the linkage assembly 203, the clamping assembly 301 wraps and fixes the cylindrical goods, so that the goods can be firmly fixed on the clamping assembly 301, and the forklift body 101 starts to transport. After transporting to the designated location, the lifting assembly 201 operates in the opposite direction, so that the goods on the clamping assembly 301 can be disassembled and stored. And with the cooperation of the driving assembly 202 and the lifting assembly 201, the goods can be rotated and the angle can be adjusted to adapt to the palletizing storage of the goods at different angles and different positions; significantly improves the safety, stability and flexibility of goods transportation. The clamping assembly 301 can firmly clamp cylindrical and irregular-shaped goods, effectively solving the risk of slipping caused by the irregular shape or unstable center of gravity of traditional forklifts; the lifting assembly 201 can adjust the gravity according to the weight of the goods, optimize the balance of the goods, and avoid the forklift tipping over due to uneven center of gravity distribution, especially when operating on complex road conditions or inclined ground. At the same time, the driving assembly 202 can rotate the goods, facilitating the adjustment of the placement position and angle of the goods according to needs during unloading, significantly improving the applicability and operation convenience of the forklift in scenarios such as warehousing and logistics.

[0038] The lifting component 201 includes a main frame 2011 disposed on the connecting portion 102. A cross plate 2012 is fixedly connected to the bottom of the main frame 2011. A hydraulic rod 2013 is fixedly connected to the top of the cross plate 2012. The output end of the hydraulic rod 2013 is fixedly connected to a driving plate 2014. A toothed belt 2015 is fixedly connected to the top of the driving plate 2014. The other end of the toothed belt 2015 is fixedly connected to a moving shaft 2018. A lifting plate 2019 is fixedly connected to the bottom of the moving shaft 2018, and the lifting plate 2019 is penetrated and rotatably connected to the driving component 202. A connecting column 2016 is fixedly connected between the main frames 2011. A rotating gear 2017 is rotatably disposed on the outer side of the connecting column 2016, and the rotating gear 2017 is meshed with the toothed belt 2015. When transporting cylindrical objects such as gasoline barrels at the port, the operator drives the forklift body 101 to the designated cargo position, inserts the clamping component 301 into the cargo, and starts to extend and retract the hydraulic rod 2013 downward so that the driving plate 2014 and the toothed belt 2015 drive the lifting plate 2019 to move upward along the rotation of the rotating gear 2017. And during the upward movement of the lifting plate 2019, the driving component 202 and the L-shaped connecting rod 2031 move upward together. And while the L-shaped connecting rod 2031 moves upward along with the toothed belt 2015, the lifting rod 2032 and the three-way rotating shaft 2033 also adjust the angle, so that the linkage member 2034 drives the clamping component 301 to approach each other along the limiting member 2024 on the moving plate 2023 to clamp and fix the cargo. After the cargo is clamped and fixed, the forklift body 101 starts to transport. And during the transportation process, through the cooperation of the moving shaft 2018 and the lifting plate 2019, the cargo clamped on the clamping component 301 can be balanced and rotated to ensure the overall balance of the cargo, and improve the safety, stability and flexibility of the cargo transportation during the cargo transportation process.

[0039] Further, the driving component 202 includes a servo motor 2021 disposed on the top of the cross plate 2012. The output end of the servo motor 2021 penetrates the lifting plate 2019 and is fixedly connected to a rotating portion 2022. The other end of the rotating portion 2022 is fixedly connected to a moving plate 2023. The other end of the moving plate 2023 is fixedly connected to a limiting member 2024. A moving block 2025 is disposed on the limiting member 2024, and the moving block 2025 is connected to the linkage assembly 203.

[0040] The linkage component 203 includes an L-shaped connecting rod 2031 arranged on the toothed belt 2015. A lifting rod 2032 is rotatably connected inside the L-shaped connecting rod 2031. A tee-shaped rotating shaft 2033 is rotatably connected to the bottom of the lifting rod 2032. A linkage member 2034 is rotatably connected inside the tee-shaped rotating shaft 2033, and the linkage member 2034 is fixedly connected to the clamping component 301. Through the cooperation of the lifting component 201 and the linkage component 203, after the clamping component 301 transports the clamped and fixed goods to the designated position, the servo motor 2021 can be driven according to the angle of the goods, so that the rotating part 2022 drives the moving plate 2023 and the linkage component 203 at the front end of the moving plate 2023 to rotate with the clamping component 301, and can cooperate with the lifting component 201, so that the goods can be rotated and the angle can be adjusted to adapt to the palletizing storage of the goods at different angles and different positions, significantly improving the safety, stability and flexibility of goods transportation.

[0041] The clamping component 301 includes a clamping rod 3011 arranged on the linkage member 2034. A pulley 3012 is rotatably connected inside the clamping rod 3011. A fork head 3014 is fixedly connected to the front end of the clamping rod 3011. A friction pad 3013 is fixedly connected to the outer wall of the clamping rod 3011, and the friction pad 3013 cooperates with the pulley 3012. A spring winding member 3015 is rotatably connected inside the clamping rod 3011. A push rod 3016 is fixedly connected to the outside of the spring winding member 3015. A rotating rod 3017 is rotatably connected to the bottom of the spring winding member 3015. One end of the rotating rod 3017 is fixedly connected to a fixing member 3018, and the fixing member 3018 cooperates with the clamping rod 3011.

[0042] During use, after the forklift body 101 drives to the position of cylindrical goods such as gasoline barrels, the fork head 3014 is inserted into both sides of the goods, and then under the cooperation of the lifting component 201 and the linkage component 203, the clamping rods 3011 on both sides begin to approach each other, and at the same time, the goods start to be clamped. And with the cooperation of the pulley 3012, the goods are clamped and conveyed to the surface of the clamping rod 3011. And as the two clamping rods 3011 continue to approach, the push rods 3016 begin to squeeze each other, causing the spring member 3015 at the other end of the push rod 3016 to rotate. While the spring member 3015 rotates, the rotating rod 3017 also rotates, so that the fixing member 3018 on the rotating rod 3017 flips and buckles onto the goods on the surface of the clamping rod 3011, clamping and limiting the goods, so that the goods are fixed and limited on the surface of the clamping rod 3011. And the friction pad 3013 on the surface of the clamping rod 3011 enhances the friction force on one end of the goods to ensure that the goods will not move or shake during transportation. After the goods are transported to the designated position, through the reverse operation of the lifting component 201 and the linkage component 203, the clamping rods 3011 on both sides begin to disperse, causing the push rods 3016 to lose the extrusion force, and the spring member 3015 at the other end of the push rod 3016 also loses the extrusion, so as to automatically flip, so that the rotating rod 3017 drives the fixing member 3018 to flip back to its original position, releasing the limit fixation of the goods. And with the cooperation of the driving component 202, the goods begin to be placed at different angles, which is convenient to adjust the placement position and angle of the goods according to needs during unloading, significantly improving the applicability and operation convenience of the forklift in scenarios such as warehousing and logistics, and reducing the workload of manually adjusting the position of the goods.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
