[0023] A drum transportation device equipped with a lifting mechanism, comprising a support frame 1, at least two protective frames 2, several sprocket drums 3, a drum drive assembly 4, a mounting frame 5, and a lifting mechanism 6. The lifting mechanism 6 includes a first driver 61, at least four guide rods 62, a fixing plate 63, and at least two lifting components 64;

[0024] The two protective frames 2 are arranged in parallel at the top of the support frame 1. The two ends of the sprocket drum 3 are respectively rotatably installed on their respective protective frames 2. Several sprocket drums 3 are arranged side by side in sequence from front to back. The drum drive assembly 4 and the mounting frame 5 are both installed on the support frame 1. The mounting frame 5 is located at the rear end of the support frame 1. The drum drive assembly 4 is used to drive the sprocket drum 3 to rotate. The first driver 61 and the four guide rods 62 are both installed on the mounting frame 5. The four guide rods 62 are all arranged in the up and down direction. The fixing plate 63 is movably inserted through the four guide rods 62 in the up and down direction. The driving end of the first driver 61 is connected to the middle of the fixing plate 63. The two lifting components 64 are both arranged on the fixing plate 63. The two lifting components 64 are both located between the two sprocket drums 3. The lifting component 64 is used to lift the tooling plate 7.

[0025] A drum transportation device equipped with a lifting mechanism in this solution is applied to a nitrogen storage bin. In this embodiment, as Figures 1-4 shown, the first driver 61 is a cylinder, there are four guide rods 62, and there are two lifting components 64. This drum transportation device is arranged at the entrance and exit of the nitrogen storage bin. When it is necessary to transport goods into the nitrogen storage bin, first place the tooling plate 7 on the sprocket drum 3 at the front end of the support frame 1, and then place the goods on the tooling plate 7. Through the driving action of the drum drive assembly 4, drive all the sprocket drums 3 to rotate, thereby driving the goods to move backward, so that the goods enter the nitrogen storage bin through the entrance of the nitrogen storage bin. When the goods are transported to the sprocket drum 3 at the rear end of the support frame 1, start the first driver 61. The first driver 61 drives the fixing plate 63 to move upward, thereby driving the two lifting components 64 to move upward. Since the two lifting components 64 are both located between the two sprocket drums 3, the two lifting components 64 can lift the tooling plate 7 to realize the lifting of the goods, which is convenient for the subsequent stacking and transportation device in the nitrogen storage bin to pick up the goods and store them on the storage rack. Further explanation, the setting of the four guide rods 62 can make the movement of the fixing plate 63 more stable, and the setting of the two lifting components 64 can make the lifting of the tooling plate 7 more stable.

[0026] Through the mutual cooperation of the first driver 61, the four vertically arranged guide rods 62, the fixing plate 63 and the two lifting components 64, this solution realizes the lifting of goods in the vertical direction. Compared with the traditional lifting mechanism that lifts goods at a certain inclination angle, this solution can improve the stability of goods during the lifting process, thereby reducing the risk of goods slipping.

[0027] Preferably, the lifting component 64 includes three cylindrical pads 641 and a strip-shaped support block 642. The three cylindrical pads 641 are arranged side by side in sequence from left to right. The strip-shaped support block 642 is installed on the three cylindrical pads 641, and the strip-shaped support block 642 is arranged in the left-right direction. In this embodiment, as Figures 1-2 shown, the setting of the three cylindrical pads 641 can not only support the strip-shaped support block 642 more stably, but also disperse the pressure of the goods during the process of lifting the goods. The setting of the strip-shaped support block 642 serves to lift and support the tooling plate 7.

[0028] Preferably, the roller drive assembly 4 includes a mounting plate 41, a second driver 42, a sprocket 43 and a plurality of chains 44. The mounting plate 41 is installed on the support frame 1. The second driver 42 is installed on the mounting plate 41. The sprocket 43 is installed on the driving end of the second driver 42. The sprocket 43 is connected to two adjacent sprocket rollers 3 through the chain 44, and each of the remaining sprocket rollers 3 is connected to its adjacent sprocket roller 3 through the chain 44. In this embodiment, the second driver 42 is a motor. As Figure 1 shown, the setting of the mounting plate 41 plays a supporting role for the second driver 42. When transporting goods, start the second driver 42, and the second driver 42 drives the sprocket 43 to rotate. The rotation of the sprocket 43 can drive the transmission of a plurality of chains 44 and the rotation of a plurality of sprocket rollers 3 to realize the transportation of goods.

[0029] Preferably, it further includes four connecting plates 8, and the mounting frame 5 is installed on the support frame 1 through the four connecting plates 8. In this embodiment, as Figure 3 shown, since the mounting frame 5 is installed on the support frame 1 through the four connecting plates 8, the mounting frame 5 and the support frame 1 can be effectively and firmly connected, increasing the overall stability of the mounting frame 5.

[0030] Preferably, it further includes a plurality of foot cups 9, and the plurality of foot cups 9 are all installed at the bottom end of the support frame 1. In this embodiment, as Figure 3 shown, since the plurality of foot cups 9 are all installed at the bottom end of the support frame 1, the support of the support frame 1 can be made more stable, preventing the support frame 1 from shaking and tipping over.

[0031] Preferably, the material of the bar support block 642 is an aluminum profile. In this embodiment, the aluminum profile has the characteristics of light weight and high strength, which enables the bar support block 642 made of aluminum profile to significantly reduce the overall weight when lifting goods, while maintaining sufficient strength and rigidity to ensure the safe loading of goods, so that it can lift heavier goods.

[0032] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
