Description

Technical Field

[0001] This application relates to the field of pipeline damage repair technology, and in particular to a clamp for repairing damage points in the anti-corrosion coating of chemical pipelines. Background Technology

[0002] In the chemical production field, chemical pipelines are prone to damage to their surface anti-corrosion layer due to long-term contact with corrosive media and external environmental erosion. If not repaired in time, this can lead to corrosion of the pipeline body, affecting production safety and pipeline service life. The commonly used repair method is to first apply a viscoelastic anti-corrosion layer to the damaged point of the pipeline to achieve initial sealing. Then, the viscoelastic anti-corrosion layer needs to be rolled with tools to remove air between layers and enhance its tightness of adhesion to the pipeline surface, thereby ensuring the anti-corrosion effect after repair.

[0003] When using viscoelastic anti-corrosion layers to repair damaged chemical pipelines by pasting and rolling them, workers usually manually roll the viscoelastic anti-corrosion layers with a roller. Without tools to limit the roller, the viscoelastic anti-corrosion layers are rolled unevenly, resulting in poor adhesion. Furthermore, if too much force is applied during the rolling process, the suspended parts of the chemical pipeline may deform.

[0004] Therefore, those skilled in the art have provided a repair fixture for damaged points in the anti-corrosion coating of chemical pipelines to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a repair fixture for damaged points of the anti-corrosion coating on chemical pipelines. The support block drives the rolling cylinder to roll back and forth on the surface of the viscoelastic anti-corrosion coating along the arc-shaped sliding groove, which can uniformly compact and adhere the viscoelastic anti-corrosion coating to the damaged point of the chemical pipeline, ensuring that the repair material is tightly bonded to the pipeline and guaranteeing the repair quality.

[0006] This application provides a technical solution for a repair fixture for damaged points in the anti-corrosion coating of chemical pipelines:

[0007] A clamp for repairing damaged points in the anti-corrosion coating of a chemical pipeline includes a fixed rod, support rings fixedly connected to both sides of the fixed rod, and a first retaining ring and a second retaining ring respectively detachable from their upper ends. The first retaining ring has an arc-shaped groove on its inner side. A support block with one side inserted into the groove is slidably connected between the upper ends of the first retaining ring and the second retaining ring. A fixed seat is fixedly fixed through the support blocks. A support rod is slidably connected to the fixed seat. A support frame is fixedly connected to the bottom end of the support rod. A rolling cylinder is rotatably connected to the inner side of the support frame. An adjusting rod is fixedly connected to the bottom end of the fixed rod.

[0008] Preferably, a screw is rotatably connected to one side of the fixed base, and the screw is threadedly connected to one side of the support rod.

[0009] In this invention, rotating the upper end of the screw allows for forward and reverse adjustment, which in turn moves the support rod up and down, thereby driving the support frame and the rolling cylinder to move synchronously. After the first retaining ring, the second retaining ring, and the support ring clamp the chemical pipeline, the above adjustment enables the rolling cylinder to accurately contact the viscoelastic anti-corrosion layer at the damaged point, thus achieving the rolling and pasting operation of the viscoelastic anti-corrosion layer.

[0010] Preferably, the lower end of the adjusting rod is threadedly connected to a sleeve, and the bottom end of the sleeve is rotatably connected to a base.

[0011] Preferably, a rotating wheel is fixed to the upper outer wall of the sleeve, and a handle is fixedly connected to the upper end of the support rod.

[0012] Preferably, another groove is provided on one side of the support ring, and the inner diameter of the left side of the first retaining ring is smaller than the inner diameter of the right side.

[0013] Preferably, the two ends of the first retaining ring are connected to the two ends of the support ring by bolts, and the two ends of the second retaining ring are connected to the two ends of the other support ring by another bolt.

[0014] In this invention, the first retaining ring, the second retaining ring, and the support ring are semi-ring structures designed to clamp chemical pipelines.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. This application uses a support block to drive a rolling cylinder to roll back and forth on the surface of the viscoelastic anti-corrosion layer along an arc-shaped groove. This can evenly compact and adhere the viscoelastic anti-corrosion layer to the damaged point of the chemical pipeline, ensuring that the repair material is tightly bonded to the pipeline and guaranteeing the repair quality.

[0017] 2. With the help of the support structure composed of the chassis, sleeve, adjusting rod and two support rings, the chemical pipeline can be stably supported during the rolling process, avoiding deformation of the pipeline when the rolling cylinder applies force, providing a stable environment for the repair of damaged points and reducing secondary damage during the repair process.

[0018] 3. The first and second retaining rings can be separated and disassembled from the support ring. During repair, the viscoelastic anti-corrosion layer can be pasted and positioned on the support ring first, and then the retaining rings can be connected and the bolts tightened to quickly complete the clamping and fixing. The operation process is simple and flexible, and it is suitable for the actual operation needs of repairing damaged points in chemical pipelines. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown, this application discloses a repair fixture for damaged points of the anti-corrosion coating of a chemical pipeline, including a fixed rod 17, support rings 10 fixedly connected to both sides of the fixed rod 17, and a first retaining ring 1 and a second retaining ring 9 whose upper ends are respectively detachable. The inner side of the first retaining ring 1 has an arc-shaped groove 2. A support block 4 with one side inserted into the groove 2 is slidably connected between the upper ends of the first retaining ring 1 and the second retaining ring 9. A fixed seat 5 is fixedly fixed through the support blocks 4. A support rod 8 is slidably connected to the fixed seat 5. A support frame 16 is fixedly connected to the bottom end of the support rod 8. A rolling cylinder 3 is rotatably connected to the inner side of the support frame 16. An adjusting rod 14 is fixedly connected to the bottom end of the fixed rod 17. A sleeve 12 is threadedly connected to the lower end of the adjusting rod 14. A base plate 13 is rotatably connected to the bottom end of the sleeve 12.

[0025] By adopting the above technical solution, the first retaining ring 1 and the second retaining ring 9 can be disassembled and separated from the support ring 10. When it is necessary to repair the damaged point of the chemical pipeline, the viscoelastic anti-corrosion layer is first attached to the damaged point of the chemical pipeline, and then the two support rings 10 are placed below the damaged point of the chemical pipeline. The sleeve 12 is rotated and moved down until the chassis 13 contacts the ground.

[0026] Then, the first retaining ring 1 and the second retaining ring 9 are placed on the upper surface of the chemical pipeline until the first retaining ring 1 and the second retaining ring 9 are respectively connected to the two support rings 10. The first retaining ring 1 and the support ring 10, the second retaining ring 9 and the other support ring 10 are fastened with bolts 15 to clamp the chemical pipeline.

[0027] At this point, the support rod 8 can be lowered until the rolling cylinder 3 contacts the viscoelastic anti-corrosion layer. The support block 4 rotates back and forth along the arc-shaped sliding groove 2, driving the rolling cylinder 3 to roll back and forth on the upper surface of the viscoelastic anti-corrosion layer until the viscoelastic anti-corrosion layer is evenly adhered to the damaged point of the chemical pipeline for repair.

[0028] During the rolling process of the rolling cylinder 3, the chemical pipeline is supported by the chassis 13, sleeve 12, adjusting rod 14 and two support rings 10, which prevents the chemical pipeline from deforming during the rolling process of the rolling cylinder 3 applying force to roll the viscoelastic anti-corrosion layer, and is beneficial to the protection of the chemical pipeline during the repair process of damaged points.

[0029] To adjust the position of the rolling cylinder 3, a screw 7 is rotatably connected to one side of the fixed base 5, and the screw 7 is threadedly connected to one side of the support rod 8. By manually rotating the upper end of the screw 7 in both directions, the support rod 8 is moved up and down, which in turn moves the support frame 16 and the rolling cylinder 3. When the chemical pipeline is clamped by the first retaining ring 1, the second retaining ring 9, and the support ring 10, the rolling cylinder 3 is adjusted until it can contact the viscoelastic anti-corrosion layer at the damaged point for rolling and bonding of the viscoelastic anti-corrosion layer.

[0030] To facilitate the rotation of the sleeve 12, a rotating wheel 11 is fixed to the upper outer wall of the sleeve 12, and a handle 6 is fixedly connected to the upper end of the support rod 8. By holding the handle 6, the support block 4 can be rotated back and forth, so that the rolling cylinder 3 can move back and forth to roll the viscoelastic anti-corrosion layer.

[0031] In order to allow the support block 4 to rotate back and forth between the first retaining ring 1 and the support ring 10, another groove 2 is provided on one side of the support ring 10, and the inner diameter of the left side of the first retaining ring 1 is smaller than the inner diameter of the right side.

[0032] To facilitate the separation and fixation of the first retaining ring 1, the second retaining ring 9 and the support ring 10, bolts 15 are connected between the two ends of the first retaining ring 1 and the two ends of the support ring 10, and another bolt 15 is connected between the two ends of the second retaining ring 9 and the two ends of the other support ring 10.

[0033] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Working principle: First, the viscoelastic anti-corrosion layer is adhered to the damaged point of the chemical pipeline. Then, two support rings 10 are placed below the damaged point of the chemical pipeline. The sleeve 12 is rotated and moved down until the base 13 contacts the ground. Then, the first retaining ring 1 and the second retaining ring 9 are placed on the upper surface of the chemical pipeline until the first retaining ring 1 and the second retaining ring 9 are respectively connected to the two support rings 10. The bolts 15 are used to tighten the first retaining ring 1 and the support ring 10, and the second retaining ring 9 and the other support ring 10, clamping the chemical pipeline. At this time, the support rod 8 can be moved down until the rolling cylinder 3 contacts the viscoelastic anti-corrosion layer. The support block 4 rotates back and forth along the arc-shaped sliding groove 2, driving the rolling cylinder 3 to roll back and forth on the upper surface of the viscoelastic anti-corrosion layer until the viscoelastic anti-corrosion layer is evenly adhered to the damaged point of the chemical pipeline for repair.
