Description

Technical Field

[0001] This utility model belongs to the field of steam pipeline technology, and more specifically, it relates to an anti-wear structure for pipeline insulation layer material. Background Technology

[0002] Traditional pipeline insulation layers are mainly made of materials such as rock wool, glass wool, and polyurethane. These materials face severe wear problems in practical applications. Due to mechanical friction and environmental erosion during daily use, the insulation layer is easily damaged, which leads to a significant decrease in insulation performance and an inability to effectively maintain the temperature stability of the medium inside the pipeline. Currently, the existing technology mainly uses thickened protective sleeves as a wear-resistant structure to address the wear problem of insulation layers.

[0003] However, most wear-resistant structures are connected and fixed using threaded fasteners. This method is extremely inconvenient to disassemble and assemble during maintenance, greatly increasing the difficulty and time cost of maintenance. At the same time, the connection strength of adjacent wear-resistant mechanisms is low, making it difficult to form a stable overall structure. The sealing, waterproofing and heat insulation capabilities are low. Under external disturbances, each wear-resistant mechanism has a large range of motion, which not only fails to effectively protect the insulation layer, but may also directly and rigidly contact the insulation layer, causing friction and further aggravating the wear of the insulation layer. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an anti-wear structure for pipe insulation layer materials, thereby solving the problem that existing anti-wear protection structures for pipe insulation layer materials are generally not easy to disassemble and have low connection strength, resulting in poor protective effects.

[0005] This utility model provides a wear-resistant structure for pipe insulation layer material, achieved through the following specific technical means:

[0006] A wear-resistant structure for pipe insulation material includes protective plates; the protective plates consist of two sets, each semi-circular, with insulating cotton wrapped inside. Each set of protective plates has connecting plates fixedly connected to both sides, and the two sets of protective plates are joined together via the connecting plates. Connecting discs, also semi-circular, are provided at both ends of the protective plates. Connecting cylinders, also semi-circular, are connected to the connecting discs. A locking protrusion is provided on the inner side of the connecting disc, locking onto the end of the connecting cylinder. An arc-shaped slide rail is provided within the connecting disc, allowing for sliding connection within the arc-shaped slide rail. The device includes an arc-shaped slider with a drive block mounted on it; a plug-in post is inserted into the connecting plate, with a flange circumferentially arranged around the plug-in post; an inner cavity is formed within the connecting plate, containing a first spring that is sleeved on the plug-in post, with both ends of the first spring contacting the inner wall of the inner cavity and the flange respectively, and the first spring being in a compressed state; one end of the plug-in post abuts against the drive block; and a plug-in hole is formed on the connecting plate, into which the plug-in post is inserted, forming a fixed connection between the connecting plate and the connecting cylinder.

[0007] Furthermore, the connecting plate is provided with clearance holes, and the clearance holes on the connecting plates on both sides of the two sets of guard plates are aligned with each other, with elastic buckles inserted into the clearance holes.

[0008] Furthermore, one set of the protective plates has positioning strips at the joints on both sides, and the other set of protective plates has positioning grooves at the joints, with the positioning strips embedded in the positioning grooves.

[0009] Furthermore, both the locking boss and the connecting cylinder are provided with receiving ring grooves. The locking boss is connected to the receiving ring groove on the connecting cylinder, and an elastic sealing ring is placed in the receiving ring groove.

[0010] Furthermore, a sleeve rod is inserted inside the arc-shaped slider, one end of which is connected to the inner wall of the arc-shaped slide. A second spring is sleeved on the sleeve rod, one end of which abuts against the arc-shaped slider and is in a compressed state. A toggle block is provided on the arc-shaped slider, one end of which protrudes outside the connecting plate.

[0011] Furthermore, the connecting plate is provided with a positioning groove, and the connecting cylinder is provided with a positioning plate, the two ends of which are engaged in the positioning groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model achieves a protective effect by setting up isolation cotton and a protective plate. The isolation cotton is wrapped around the outside of the pipe to prevent hard objects in the anti-wear structure from directly contacting the insulation layer of the pipe. The protective plate is fastened to the outside of the isolation cotton and covers the insulation layer of the pipe.

[0014] 2. This utility model, by setting an elastic buckle, can easily fix the two sets of guard plates after they are connected by snapping the elastic buckle into the clearance hole of the connecting plate. Moreover, compared with the traditional threaded fastener connection, this connection method is easier to disassemble.

[0015] 3. This utility model further enhances the sealing performance at the joint after the connecting disc and the connecting cylinder are connected by inserting the elastic sealing ring into the receiving ring groove between the locking boss and the connecting cylinder, thereby reducing the degree of heat loss from the pipeline between adjacent anti-wear structures and enhancing the heat preservation effect.

[0016] 4. This utility model, by setting plug-in posts and plug-in holes, with the plug-in posts inserted into the plug-in holes, connects and fixes the connecting plate and the connecting cylinder, thereby connecting multiple anti-wear mechanisms on the outside of the pipe into a whole, reducing its range of motion when subjected to external disturbances, avoiding direct contact between the protective plate and the pipe insulation material, and better achieving the anti-wear function.

Connecting cylinders 8 are connected to the connecting plates 7, and the connecting cylinders 8 are also semi-circular. The connecting plates 7 have locking protrusions 9 on their inner sides, and the locking protrusions 9 are locked to the ends of the connecting cylinders 8; an arc-shaped slide rail 12 is provided in the connecting plates 7, and an arc-shaped slider 1 is slidably connected in the arc-shaped slide rail 12. 3. A drive block 14 is provided on the arc-shaped slider 13; a plug-in post 15 is inserted into the connecting plate 7, and a flange 16 is provided around the plug-in post 15; an inner cavity 17 is opened in the connecting plate 7, and a first spring 18 is placed in the inner cavity 17. The first spring 18 is sleeved on the plug-in post 15, and the two ends of the first spring 18 are in contact with the inner wall of the inner cavity 17 and the flange 16 respectively, and the first spring 18 is in a compressed state; one end of the plug-in post 15 abuts against the drive block 14; a plug-in hole 22 is opened on the connecting plate 7, and the plug-in post 15 is inserted into the plug-in hole 22 to form a fixed connection between the connecting plate 7 and the connecting cylinder 8.

[0030] Among them, such as Figure 3 As shown, the connecting plate 4 has clearance holes 5. The clearance holes 5 on the connecting plates 4 on both sides of the two sets of guard plates 1 are aligned with each other, and elastic buckles 6 are inserted into the clearance holes 5. By inserting the elastic buckles 6 into the clearance holes 5 of the connecting plate 4, it is easy to fix the two sets of guard plates 1 after they are connected. Compared with traditional threaded fastener connections, this connection method is easier to disassemble.

[0031] Among them, such as Figure 3 As shown, one set of protective plates 1 has positioning strips 2 at the joint on both sides, and another set of protective plates 1 has positioning grooves 3 at the joint, with the positioning strips 2 embedded in the positioning grooves 3; through the cooperation between the positioning grooves 3 and the positioning strips 2, the sealing performance at the joint after the two sets of protective plates 1 are joined is further enhanced, so as to reduce the heat loss of the pipeline.

[0032] Among them, such as Figure 6 As shown, both the locking boss 9 and the connecting cylinder 8 are provided with receiving annular grooves 10. The locking boss 9 and the receiving annular grooves 10 on the connecting cylinder 8 are connected. An elastic sealing ring 11 is placed in the receiving annular groove 10.

[0033] Among them, such as Figure 7As shown, a sleeve rod 19 is inserted inside the arc-shaped slider 13. One end of the sleeve rod 19 is connected to the inner wall of the arc-shaped slide rail 12. A second spring 20 is sleeved on the sleeve rod 19. One end of the second spring 20 abuts against the arc-shaped slider 13 and is in a compressed state. A toggle block 21 is provided on the arc-shaped slider 13, with one end of the toggle block 21 protruding outside the connecting plate 7. The insertion post 15 is inserted into the insertion hole 22, so that the connecting plate 7 and the connecting cylinder 8 are connected and fixed, realizing the connection of multiple anti-wear mechanisms on the outside of the pipe into one. Overall, this reduces the range of motion when subjected to external disturbances, prevents the protective plate 1 from directly contacting the pipe insulation material, and better achieves the anti-wear function. If the anti-wear structure needs to be removed during pipe maintenance, the arc-shaped slider 13 can be moved within the arc-shaped slide rail 12 by the toggle block 21, so that the drive block 14 and the plug-in post 15 are separated from each other. Under the pressure of the first spring 18 on the flange 16, the plug-in post 15 pops out from the plug-in hole 22, and the connecting plate 7 and the connecting cylinder 8 can be disassembled.

[0034] Among them, such as Figure 7 As shown, the connecting plate 7 has a positioning groove 23, and the connecting cylinder 8 has a positioning plate 24. The two ends of the positioning plate 24 are inserted into the positioning groove 23.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In this invention, firstly, insulating cotton 25 is wrapped around the outside of the pipe to prevent the hard parts of the wear-resistant structure from directly contacting the insulation layer of the pipe; then, the two sets of protective plates 1 of the wear-resistant structure are fastened onto the pipe, and elastic buckles 6 are inserted into the clearance holes 5 to form a seal at the joint of the two sets of protective plates 1; then, the two sets of connecting cylinders 8 are also fastened onto the pipe, with the locking boss 9 engaging with the receiving annular groove 10 of the connecting cylinder 8, and filled with an elastic sealing ring 11; adjacent wear-resistant structures are connected by connecting cylinders 8, and the insertion post 15 is inserted into the insertion hole 22, so that the connecting plate 7 and the connecting... The cylinder 8 is fixed in place, connecting multiple anti-wear mechanisms on the outside of the pipe into a whole, reducing its range of motion when subjected to external disturbances, avoiding direct contact between the protective plate 1 and the pipe insulation material, and better achieving the anti-wear function; if the anti-wear structure needs to be removed during pipe maintenance, the arc-shaped slider 13 can be moved within the arc-shaped slide rail 12 by the toggle block 21, so that the drive block 14 and the plug-in post 15 are separated from each other.
