Description

Technical Field

[0001] This utility model relates to the field of transfer device design technology, and in particular to a shell lifting device. Background Technology

[0002] A pneumatic rod, also known as a cylinder piston rod, is a component used in pneumatic equipment to convert pneumatic force into mechanical motion. During the production of the cylindrical housing of a pneumatic rod, the housing needs to be transferred between various production machines.

[0003] In existing shell lifting equipment, a combination of parallel rotating shafts and conveyor belts or chains is typically used to achieve vertical transport of objects. However, these traditional structures are mostly simple in layout, with rotating shafts often arranged in a simple symmetrical or linear pattern, resulting in an inefficient transport path. This can easily lead to problems such as unstable center of gravity and discontinuous operation during the lifting process. Furthermore, the underutilization of rotating shaft space results in a loose overall structure, occupying excessive installation space and limiting further improvements in transport efficiency and stability, making it difficult to meet the demands of efficient and compact production processes. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a shell lifting device to solve the problems of unstable transportation, low space utilization and large space occupation of the existing shell transportation device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A shell lifting device includes two mounting plates arranged parallel to each other. A first rotating shaft and a second rotating shaft are rotatably arranged between the two mounting plates. The first and second rotating shafts are horizontally arranged. A third rotating shaft and a fourth rotating shaft are arranged between the two mounting plates. The third rotating shaft is located above the first and second rotating shafts. The fourth rotating shaft is located above the side of the second rotating shaft opposite to the first rotating shaft and is lower than the third rotating shaft. Transfer components are provided on the first, second, third, and fourth rotating shafts.

[0007] The present invention is further configured such that: the transfer assembly includes a plurality of sprockets, a chain and a plurality of transfer blocks, the plurality of sprockets are respectively fixed on a first rotating shaft, a second rotating shaft, a third rotating shaft and a fourth rotating shaft, the chain is sleeved on the plurality of sprockets, and the plurality of transfer blocks are uniformly fixed on the chain.

[0008] The present invention is further configured such that several of the transfer blocks are L-shaped on the side.

[0009] The present invention is further configured such that: an anti-slip layer is fixed on the side of the transfer block used to support the shell, and a buffer layer is provided on the side of the transfer block opposite to the anti-slip layer.

[0010] The present invention is further configured such that: a fifth rotating shaft is adjustable between the two mounting plates, and an adjusting sprocket for cooperating with the chain is fixed on the fifth rotating shaft.

[0011] The present invention is further configured such that: two mounting plates are provided with elongated adjustment holes facing each other, and adjustment rods are slidably inserted into the two adjustment holes; the fifth rotating shaft is rotatably sleeved on the adjustment rods; a screw is rotatably provided on one of the mounting plates, and one end of the adjustment rod is threaded onto the screw; a sliding rod is fixed on the other mounting plate at the same level as the screw, and the other end of the adjustment rod is slidably sleeved on the sliding rod.

[0012] Compared to the beneficial effects achieved by existing technologies:

[0013] This application employs a specific spatial layout design of a first, second, third, and fourth rotating shaft between mounting plates—the third rotating shaft is positioned above and between the first and second rotating shafts, and the fourth rotating shaft is located above the second rotating shaft on the side opposite to the first rotating shaft and at a lower height than the third rotating shaft. Combined with transfer components mounted on each rotating shaft, this constructs an asymmetrical multi-axis linkage conveying path. This structure effectively optimizes the center of gravity transfer trajectory of the outer casing during lifting, enhancing the continuity and synchronization of equipment operation. It not only significantly improves conveying efficiency and stability but also reduces the overall footprint of the equipment through more compact three-dimensional space utilization.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] Reference Figures 1-3 This application discloses a shell lifting device, mainly used for transporting shells with a cylindrical shape. It includes two mounting plates 1, arranged parallel to each other. A first rotating shaft 2 and a second rotating shaft 3 are rotatably mounted between the two mounting plates 1. The first rotating shaft 2 and the second rotating shaft 3 are horizontally arranged. A third rotating shaft 4 and a fourth rotating shaft 5 are located between the two mounting plates 1. The third rotating shaft 4 is positioned above the first rotating shaft 2 and the second rotating shaft 3. The fourth rotating shaft 5 is located above the side of the second rotating shaft 3 facing away from the first rotating shaft 2, and is lower than the third rotating shaft 4. Transfer components are provided on the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4, and the fourth rotating shaft 5. Figure 1 and Figure 2 As shown, the transfer assembly includes several sprockets 6, a chain 7, and several transfer blocks 8. The sprockets 6 are respectively fixed on a first rotating shaft 2, a second rotating shaft 3, a third rotating shaft 4, and a fourth rotating shaft 5. The chain 7 is sleeved on the sprockets 6. The transfer blocks 8 are evenly fixed on the chain 7, and the transfer blocks 8 are L-shaped from the side. This arrangement, by driving the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4, or the fourth rotating shaft 5, and through the cooperation of the sprockets 6 and the chain 7 and the layout of the multiple rotating shafts, enables the housing to be lifted and unloaded on the transfer blocks 8.

[0021] like Figure 2 As shown, an anti-slip layer 9 is fixed on the side of the transfer block 8 that receives the housing, and a buffer layer 10 is provided on the side of the transfer block 8 opposite to the anti-slip layer 9. The anti-slip layer 9 can effectively prevent the housing from slipping when lifting it, and the buffer layer 10 is designed to support and protect the housing when it is transported between the third rotating shaft 4 and the fourth rotating shaft 5, and when the housing moves from one transfer block 8 to another. Both the anti-slip layer 9 and the buffer layer 10 are made of rubber.

[0022] like Figure 1 and Figure 3 As shown, a fifth rotating shaft 11 is adjustable between the two mounting plates 1, and an adjusting sprocket 12 for cooperating with the chain 7 is fixed on the fifth rotating shaft 11. Elongated adjusting holes 13 are opened opposite each other on the two mounting plates 1, and adjusting rods 14 slide through the two adjusting holes 13. The fifth rotating shaft 11 is rotatably sleeved on the adjusting rods 14. A screw 15 is rotatably mounted on one of the mounting plates 1, and one end of the adjusting rod 14 is threaded onto the screw 15. A sliding rod 16, horizontal with the screw 15, is fixed on the other mounting plate 1, and the other end of the adjusting rod 14 is slidably sleeved on the sliding rod 16. This arrangement allows the adjusting rod 14 and the fifth rotating shaft 11 to move between the two mounting plates 1 by rotating the screw 15, thereby adjusting the tension of the chain 7 and slightly adjusting the distance between the transfer block 8 and the external feeding device.

[0023] Working principle:

[0024] When the equipment starts, it drives any one of the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4, or the fourth rotating shaft 5, which drives the sprocket 6 fixed on it to rotate, thereby driving the chain 7 sleeved on all the sprockets 6 to rotate in a cycle. Multiple transfer blocks 8, which are evenly fixed on the chain 7, then move along the preset path with the chain 7. When the shell is placed on the low transfer block 8, its "L"-shaped structure can effectively support the cylindrical shell, and the rubber anti-slip layer 9 set on the bearing surface of the transfer block 8 can significantly increase the friction and prevent the shell from slipping during the lifting process. The chain 7 drives the transfer block 8 to run from the first rotating shaft 2 to the third rotating shaft 4. After the initial lifting is completed, the shell in the high area between the third rotating shaft 4 and the fourth rotating shaft 5 needs to be transferred from one transfer block 8 to the next transfer block 8. At this time, the rubber buffer layer 10 set on the back of the transfer block 8 can effectively support and buffer the shell during this critical transition stage, avoiding damage to the shell caused by hard impact. Finally, the shell is continuously transported to the high position of the equipment and the unloading is completed. In addition, by rotating the screw 15, the equipment can drive the adjusting rod 14 and the adjusting sprocket 12 on the fifth rotating shaft 11 to move horizontally along the adjusting hole 13 on the mounting plate 1, so as to accurately adjust the tension of the chain 7 and finely adjust the relative distance between the transfer block 8 and the external feeding device, thereby ensuring that the entire conveying and lifting process is continuous, stable, reliable and efficient.
