[0002] Flanges are a common connecting component in industrial production and piping systems, widely used in connecting various pipes, valves, and equipment. During transportation, storage, and installation, the surface of flanges is susceptible to damage from impacts and friction.

[0003] For example, CN221186492U discloses a flange placement rack, which includes a support frame. Each support frame has a partition on its opposite sides, and each partition has a fixing anti-tipping mechanism at its bottom. The fixing anti-tipping mechanism includes a reciprocating screw, and the outer surface of the reciprocating screw is threaded with a clamping plate for fixing the flange and preventing it from tipping over after being impacted by external forces. By fixing and securing the flange assembly with the fixing anti-tipping mechanism, the flange assembly can be effectively prevented from moving or shaking, reducing the risk of damage.

[0004] The above-mentioned device is used by storing multiple sets of flanges in contact with each other. During transportation and storage, the flanges are prone to damage from collisions and friction, resulting in wear, scratches and other defects on the flange surface. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flange protection device that is easy to disassemble and assemble, so as to solve the problem that the flange surface is easily subjected to collisions, friction, damage and scratches during transportation and storage.

Multiple sets of movable arc plates are threadedly connected to the screw rod, each movable arc plate is located between two adjacent fixed arc plates, so that the multiple sets of movable arc plates correspond one-to-one with the multiple sets of fixed arc plates. The screw rod is used to drive each movable arc plate to move closer to or away from the corresponding fixed arc plate.

[0007] Compared with the prior art, this utility model has the following advantages: by evenly distributing multiple placement slots on the placement rack, each placement slot is equipped with an independent limiting unit. The movable arc plate and the fixed arc plate in the limiting unit are arranged in a one-to-one correspondence. One movable arc plate and one fixed arc plate clamp and fix one flange, which can keep the flange stable during placement and transportation, and reduce wear caused by shaking and collision. At the same time, the movable arc plate driven by the screw can not only clamp and fix the flange, but also clamp flanges of different specifications, improving practicality.

[0008] Preferably, each placement slot is provided with multiple sets of placement strips, with gaps formed between adjacent placement strips, and each movable arc plate and each fixed arc plate are located on the upper side of the corresponding placement strip.

[0009] Preferably, each placement strip is provided with a rubber strip.

[0010] Preferably, a sliding groove is provided on the side of each placement slot away from the multiple sets of fixed arc plates, and the end of the screw and the corresponding movable arc plate away from the fixed arc plate are both located in the sliding groove.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a flange protection device that is easy to assemble and disassemble. It includes a placement rack 1 with multiple placement slots 2 evenly distributed on it for placing flanges; multiple limiting units are respectively set in the corresponding placement slots 2, each limiting unit includes a screw 3 rotatably set in the corresponding placement slot 2, and multiple fixed arc plates 202 evenly distributed in the placement slot 2 away from the screw 3. Multiple movable arc plates 302 are threadedly connected to the screw 3, and each movable arc plate 302 is located between two adjacent fixed arc plates 202, so that the multiple movable arc plates 302 correspond one-to-one with the multiple fixed arc plates 202. The screw 3 is used to drive each movable arc plate 302 to move closer to or away from the corresponding fixed arc plate 202.

[0022] The detailed working process of this embodiment is as follows: Multiple placement slots 2 are evenly distributed on the placement rack 1, and each placement slot 2 is equipped with an independent limiting unit. The movable arc plate 302 and the fixed arc plate 202 in the limiting unit are arranged in a one-to-one correspondence. One movable arc plate 302 and one fixed arc plate 202 clamp and fix a flange, which can keep the flange stable during placement and transportation, and reduce wear caused by shaking and collision. At the same time, the movable arc plate 302 driven by the screw 3 can not only clamp and fix the flange, but also clamp flanges of different specifications.

[0023] The curved design of the movable arc plate 302 and the fixed arc plate 202 matches the circumference of the flange, allowing for better contact with the flange surface and even pressure distribution around the flange circumference, thus improving stability. The screw 3 allows the operator to precisely control the proximity of the movable arc plate 302 to the fixed arc plate 202 based on the flange's size and material, thereby adjusting the clamping force. This ensures the flange is securely fixed without damaging the flange surface due to excessive clamping force.

[0024] like Figure 2 As shown, each placement slot 2 is provided with multiple sets of placement strips 201, and a gap is formed between two adjacent placement strips 201. Each movable arc plate 302 and each fixed arc plate 202 are located on the upper side of the corresponding placement strip 201.

[0025] The detailed working process of this embodiment is as follows: Multiple sets of placement strips 201 provide stable support for the flange, and the placement strips 201 reduce the contact area between the flange and the placement groove 2. When placing the flange, only the placement strips 201 contact the bottom of the flange, which helps to reduce friction and wear caused by contact. The movable arc plate 302 and the fixed arc plate 202 are located on the upper side of the placement strips 201, that is, when the screw 3 drives the movable arc plate 302 to move closer to or away from the fixed arc plate 202, it will not be interfered with by the placement strips 201. The movable arc plate 302 and the fixed arc plate 202 can smoothly clamp or release the flange, ensuring the normal realization of the limiting function.

[0026] The presence of gaps makes cleaning the placement slot 2 easier. When cleaning the placement slot 2, debris and dust can be discharged through the gaps, or tools can be used to more easily reach into the interior of the placement slot 2 for cleaning, keeping the placement slot 2 clean and providing a good placement environment for the flange.

[0027] like Figure 4 As shown, each placement strip 201 is provided with a rubber strip 203.

[0028] The detailed working process of this embodiment is as follows: The rubber strip 203 is elastic, which can effectively prevent the flange from directly and rigidly contacting the placement strip 201. When the flange is placed on the placement strip 201, the rubber strip 203 can buffer the impact force, reducing the possibility of scratches and wear on the flange surface caused by collision. At the same time, during transportation or handling, the device will inevitably be subjected to vibration and impact. The elasticity of the rubber strip 203 can absorb this energy, further reducing the impact on the flange and ensuring the integrity of the flange surface.

[0029] like Figure 4 As shown, a sliding groove 204 is provided on the side of each placement slot 2 away from the multiple sets of fixed arc plates 202, and the screw 3 and the end of the corresponding movable arc plate 302 away from the fixed arc plate 202 are both located in the sliding groove 204.

[0030] The detailed working process of this embodiment is as follows: the end of the movable arc plate 302 away from the fixed arc plate 202 is located in the slide groove 204, which allows the movable arc plate 302 to move linearly along the direction of the slide groove 204 under the drive of the screw 3. This linear movement ensures that the movable arc plate 302 can accurately approach or move away from the fixed arc plate 202, realizing reliable clamping and loosening operations on the flange, and avoiding the situation of the movable arc plate 302 tilting or getting stuck during the movement.

[0031] like Figure 3 As shown, each fixed arc plate 202 and each movable arc plate 302 have a rubber pad 303 on their inner arc surface.

[0032] The detailed working process of this embodiment is as follows: With the rubber pad 303 in place, when the fixed arc plate 202 and the movable arc plate 302 clamp the flange, direct rigid contact between the metal arc plate and the flange surface is avoided. This effectively prevents the flange surface from being scratched, indented, or deformed. When the screw 3 drives the movable arc plate 302 to approach the fixed arc plate 202 to clamp the flange, the rubber pad 303 can act as a buffer. It can disperse the clamping force, making the flange surface more evenly stressed, avoiding damage due to excessive local stress, and ensuring the safety of the flange during the clamping process.

[0033] like Figure 2 As shown, each placement slot 2 has a support leg 101 at the four corners of the bottom side and a slot 103 at the four corners of the top side, with each support leg 101 corresponding to a slot 103.

[0034] The detailed working process of this embodiment is as follows: With the support leg 101 and the slot 103, the placement rack 1 can be stacked tightly together, and more placement racks 1 can be stacked in a limited space, which improves the space utilization rate in the storage and transportation process. At the same time, during the handling process, since the support leg 101 and the slot 103 have accurately connected the placement rack 1 together, the staff can more easily carry the stacked placement rack 1 as a whole, which improves the handling efficiency.

[0035] like Figure 2 As shown, the ratio of the depth of each slot 103 to the length of each support leg 101 is 1:2.

[0036] The detailed working process of this embodiment is as follows: Under the 1:2 ratio setting, a gap is formed between two adjacent placement racks 1, which facilitates stacking.

[0037] like Figure 3 As shown, each screw 3 has a butterfly cap 301 at its end, and each butterfly cap 301 is located outside the corresponding placement frame 1.

[0038] The detailed working process of this embodiment is as follows: With the butterfly cap 301 set, it is convenient to control the screw 3.

[0039] The implementation principle of this application embodiment is as follows: First, the flange is placed on the placement strip 201 between the corresponding movable arc plate 302 and the fixed arc plate 202. After placement, the screw 3 is turned to drive the movable arc plate 302 to approach the corresponding fixed arc plate 202 to clamp the flange. Then, the placement rack 1 is stacked together in sequence. By rotating the screw 3, the corresponding movable arc plates 302 can be adjusted synchronously, so that the flanges in the whole row can be fixed or unfixed in batches, thereby realizing rapid storage and transportation before transportation, or retrieval after transportation.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
