[0029] The forklift unit 100 includes a forklift body 101, the top of which is fixedly connected to a connecting portion 102. When transporting cylindrical objects such as gasoline barrels at a port, an operator drives the forklift body 101 to a designated location of the goods, and transports the goods through the connecting portion 102 and the frame unit 200. The frame unit 200 includes a lifting assembly 201 on the connecting portion 102, a driving assembly 202 disposed on the lifting assembly 201, a linkage assembly 203 disposed on the driving assembly 202, a stop block 204 disposed on the lifting assembly 201, and a stop slot 205 disposed on the lifting assembly 201, wherein the stop slot 205 is slidably connected to the stop block 204. The clamping unit 300 includes a clamping assembly 301 disposed on the linkage assembly 203.

[0030] When transporting cylindrical or special-shaped goods at the port, the operator drives the forklift body 101 to the designated cargo position, and then uses the clamping assembly 301 to insert the cargo. After the clamping preparation is completed, 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, and at the same time as the driving assembly 202 moves upward, the linkage assembly 203 also moves upward with the clamping assembly 301, so that the clamping assembly 301 on the linkage assembly 203 starts to move from both sides to the middle of the cargo, thereby clamping and fixing the cargo, and at the same time, the clamping assembly As the linkage assembly 203 is driven closer, the clamping assembly 301 wraps and fixes the cylindrical cargo, so that the cargo 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 cargo 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 cargo can be rotated and the angle can be adjusted to adapt to the stacking and storage of the cargo at different angles and positions; the safety, stability and flexibility of cargo transportation are significantly improved.

At the same time, the driving component 202 can realize 360-degree rotation of the goods, which is convenient for adjusting the placement position and angle of the goods according to needs during unloading, significantly improving the applicability and operational convenience of forklifts in warehousing, logistics and other scenarios.

[0031] The lifting assembly 201 includes a main frame 2011 disposed on the connecting portion 102, a horizontal plate 2012 fixedly connected to the bottom of the main frame 2011, a hydraulic rod 2013 fixedly connected to the top of the horizontal plate 2012, a driving plate 2014 fixedly connected to the output end of the hydraulic rod 2013, a toothed belt 2015 fixedly connected to the top of the driving plate 2014, a moving shaft 2018 fixedly connected to the other end of the toothed belt 2015, a lifting plate 2019 fixedly connected to the bottom of the moving shaft 2018, and the lifting plate 2019 penetrates and is rotatably connected to the driving assembly 202. A connecting column 2016 is fixedly connected between the main frame 2011, and a rotating gear 2017 is rotatably provided on the outer side of the connecting column 2016, and the rotating gear 2017 is meshed and connected to 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 assembly 301 into the cargo, and starts to extend and retract the hydraulic rod 2013 downward to make the driving plate 2014 and the toothed belt 2015 move the lifting plate 2019 upward along with the rotation of the rotating gear 2017, and in the process of the lifting plate 2019 moving upward, the driving assembly 202 and the L-shaped connecting rod 2031 move upward together, and the lifting rod 2031 moves upward along with the toothed belt 2015. 032 and the three-way rotating shaft 2033 are also adjusted in angle, so that the linkage part 2034 brings the clamping assembly 301 and starts to approach each other along the limit part 2024 on the moving plate 2023 to clamp and fix the goods. After the goods are clamped and fixed, they are transported by the forklift body 101, and during the transportation process, the goods clamped on the clamping assembly 301 can be rotated in a balanced manner through the cooperation of the moving shaft 2018 and the lifting plate 2019 to ensure the overall balance of the goods, thereby ensuring that the safety, stability and flexibility of the goods transportation are improved during the goods transportation process.

[0033] The linkage assembly 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 three-way rotating shaft 2033 is rotatably connected at the bottom of the lifting rod 2032, a linkage member 2034 is rotatably connected inside the three-way rotating shaft 2033, and the linkage member 2034 is fixedly connected to the clamping assembly 301. After the clamping assembly 301 transports the clamped and fixed goods to the designated position through the cooperation of the lifting assembly 201 and the linkage assembly 203, the servo motor 2021 can be driven according to the angle of the goods, so that the rotating part 2022 rotates with the moving plate 2023 and the linkage assembly 203 at the front end of the moving plate 2023 and the clamping assembly 301, and can cooperate with the lifting assembly 201, so that the goods can be rotated and the angle can be adjusted to adapt to the stacking storage of goods at different angles and different positions, which significantly improves the safety, stability and flexibility of goods transportation.

[0034] The clamping assembly 301 includes a clamping rod 3011 disposed on the linkage member 2034, the clamping rod 3011 is rotatably connected to a pulley 3012, the front end of the clamping rod 3011 is fixedly connected to a fork 3014, the outer wall of the clamping rod 3011 is fixedly connected to a friction pad 3013, and the friction pad 3013 cooperates with the pulley 3012. The clamping rod 3011 is rotatably connected to a coil spring 3015, and the outer side of the coil spring 3015 is fixedly connected to a push rod 3016.

[0035] During use, after the forklift body 101 is driven to the position of cylindrical goods such as gasoline barrels, the fork head 3014 is inserted into the two sides of the goods and then the clamping rods 3011 on both sides begin to approach each other with the cooperation of the lifting component 201 and the linkage component 203, and the goods begin to be clamped, and the goods are clamped and transported to the surface of the clamping rod 3011 with the cooperation of the pulley 3012, and the clamping rods 3011 on both sides continue to approach the lower push rod 3016 and begin to squeeze each other, so that the coil spring part 3015 at the other end of the push rod 3016 rotates, and the rotating rod 3017 rotates at the same time as the coil spring part 3015 rotates, so that the fixing part 3018 on the rotating rod 3017 is flipped and buckled, and engaged with the goods on the surface of the clamping rod 3011, so as to clamp and limit 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 clamp 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 location, the lifting component 201 and the linkage component 203 are operated in reverse, so that the clamp rods 3011 on both sides begin to disperse, causing the push rod 3016 to lose its squeezing force, and the coil spring component 3015 at the other end of the push rod 3016 also loses its squeezing force, thereby automatically flipping, so that the rotating rod 3017 flips back to its original position with the fixing component 3018, 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 for adjusting the placement position and angle of the goods according to needs during unloading, significantly improving the applicability and operational convenience of the forklift in warehousing, logistics and other scenarios, and reducing the workload of manually adjusting the position of the goods.
