Technical Field

[0001] This utility model belongs to the field of flange transfer, specifically a transfer device for flange processing. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts to each other. It is used for connecting pipe ends, and also for connecting two pieces of equipment at the inlet and outlet. Flanges are key components for connecting pipelines and equipment, enabling stable connections and sealing, and ensuring the normal operation of the system.

[0003] During the flange processing, for short-distance flange transfer, the existing technology often uses a trolley to transfer the flanges. The trolley is vertically equipped with a column, the flanges are passed through the column and stacked on the trolley, and then the trolley is manually pushed to transfer the flanges to be processed.

[0004] However, the column is difficult to fit flanges of different sizes, resulting in poor versatility and an inability to effectively prevent flange shifting and shaking, thus increasing the risk of damage.

[0005] In summary, this utility model provides a transfer device for flange processing to solve the above problems. Utility Model Content

[0016] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0017] Example 1 like Figure 1-6 As shown, this is the first embodiment of the present invention. This embodiment provides a transfer device for flange processing, including a trolley 1. A storage box 2 is fixed on the top of the trolley 1. A limiting mechanism 3 is provided in the inner cavity of the storage box 2. The limiting mechanism 3 includes a first support plate 301, which is fixed in the inner cavity of the storage box 2. Cylinders 302 are fixed at the four corners of the top of the first support plate 301. The telescopic ends of the cylinders 302 are fixedly connected to a second support plate 303. Three sets of air expansion shafts 304 are provided on the top of the first support plate 301.

[0018] like Figure 1-6 As shown, the trolley 1 carries the storage box 2, and the storage box 2 is fixed with the first support plate 301. When the flange needs to be transferred, the second support plate 303 can be driven to rise to the appropriate position by the cylinder 302. The second support plate 303 supports the flange. The flange is sleeved on the air expansion shaft 304. As the flange is gradually placed, the cylinder 302 drives the second support plate 303 to slowly descend until the flange is placed. At this time, the air expansion shaft 304 expands to limit and fix the flange, preventing the flange position from shifting due to shaking during the transfer process.

[0019] Example 2 Reference Figure 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0020] In this embodiment, the bottom end of the air shaft 304 is fixedly connected to an air pipe 305, the top of the trolley 1 is fixedly connected to an air compressor 4, the air outlet of the air compressor 4 is connected to the air inlet of the air pipe 305, the air outlet of the air pipe 305 is connected to the bottom of the air shaft 304, the surface of the first support plate 301 is provided with a fixing hole 306, the bottom of the air shaft 304 is fixedly installed in the inner cavity of the fixing hole 306, the surface of the second support plate 303 is provided with a first placement hole 307, the upper end of the air shaft 304 passes through the first placement hole 307, the key strip of the air shaft 304 is fixedly fixed with an anti-slip pad 308 along the axial direction, the inner cavity of the first placement hole 307 is provided with a second placement hole 309, the second placement hole 309 is provided with a second sliding groove 310, and the inner cavity of the first placement hole 307 is movably installed with a washer 311.

[0021] like Figure 2-5 As shown, when the flange needs to be transferred, the fixing hole 306 is responsible for fixing the air expansion shaft 304. The air compressor 4 supplies air to the air pipe 305, thereby causing the key strip of the air expansion shaft 304 to expand. The key strip of the air expansion shaft 304 pushes the anti-slip pad 308 to expand. The anti-slip pad 308 ensures that the flange can be fixed more securely. The design of the first placement hole 307, the second placement hole 309 and the second slide groove 310 facilitates the placement of flanges of different models. If the flange model is too small and cannot be placed on the surface of the second placement hole 309, the gasket 311 is placed on the surface of the second placement hole 309, and the flange can be placed on the surface of the gasket 311. The degree of expansion of the air expansion shaft 304 can be adaptively adjusted according to the size and specifications of the flange, ensuring that the flange surface is not squeezed and damaged while being limited and fixed, effectively improving the adaptability of the device to flanges of different specifications.

[0022] Example 3 Reference Figure 1 , Figure 5 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0023] In this embodiment, a push handle 5 is fixed to the top of the trolley 1, and universal wheels 6 are fixedly connected to the four corners of the bottom surface of the trolley 1. A hook 7 is fixedly connected to one side of the storage box 2. The hook 7 is used to hang the washer 311. A first sliding groove 8 is opened on both sides of the inner cavity of the storage box 2. A slider 312 is opened at each of the four corners of the second support plate 303. The slider 312 extends into the inner cavity of the first sliding groove 8 and is slidably connected to it. A hole 9 adapted to the air pipe 305 is opened at the bottom of the storage box 2 near the air compressor 4. The air pipe 305 passes through the hole 9 into the inner cavity of the storage box 2.

[0024] like Figure 1 , Figure 5 and Figure 6As shown, hook 7 is responsible for suspending washer 311. Through the coordinated cooperation of slider 312 and first slide groove 8, the lifting and lowering of second support plate 303 is limited. After the flange is placed, air pipe 305 passes through the inner cavity of hole 9 to connect air expansion shaft 304 and air compressor 4, thereby supplying air and causing air expansion shaft 304 to expand, effectively limiting the flange. Then, the flange is transferred with the help of push handle 5 and caster wheel 6, realizing a smooth transition of the flange from placement to transfer, further reducing the risk of damage, and laying a good foundation for the precise positioning of subsequent processing procedures.

[0025] In use, when the flange needs to be moved, the second support plate 303 is driven by the cylinder 302 to rise to the appropriate position. The flange is then fitted onto the air expansion shaft 304 and placed on the surface of the second placement hole 309. After the flange is placed, air is supplied by the air compressor 4 to the air pipe 305 passing through the inner cavity of the hole 9, causing the key strip of the air expansion shaft 304 to expand. The key strip of the air expansion shaft 304 pushes the anti-slip pad 308 to expand, thereby effectively limiting the flange. If the inner diameter of the flange is too large, the key strip of the air expansion shaft 304 can be further... The expansion pushes the anti-slip pad 308 into the inner cavity of the second slide groove 310 to limit and fix the large flange. If the inner diameter of the flange is too small to be placed on the surface of the second storage hole 309, the washer 311 is removed from the hook 7 and installed on the surface of the second storage hole 309. The small flange can then be placed on the surface of the washer 311. Subsequently, the small flange is limited and fixed by the key strip of the air shaft 304 and the anti-slip pad 308. After the limiting and fixing is completed, the push handle 5 is pushed, and the flange is transferred by the universal wheel 6.
