Description

Technical Field

[0001] This utility model relates to the field of boiler water-cooled wall tube technology, and in particular to a wear-resistant and explosion-proof boiler water-cooled wall tube. Background Technology

[0002] In the boiler systems of thermal power plants, water-cooled wall tubes of coal-fired boilers are mostly fixed by clamps and two bolts. During use, when the water-cooled wall tubes vibrate, they are prone to continuous friction with the clamps, leading to wear and cracking. This method has the disadvantage of not being convenient for quick anti-wear fixing of water-cooled wall tubes, and the fixing and disassembly efficiency of two bolts and clamps is low. It requires personnel to use special tools for disassembly and assembly, which is time-consuming and labor-intensive. This makes it inconvenient for subsequent disassembly, renovation and replacement of water-cooled wall tubes and cannot meet the usage requirements. Therefore, an anti-wear and explosion-proof boiler water-cooled wall tube is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wear-resistant and explosion-proof boiler water-cooled wall tube, which effectively solves the deficiencies of the prior art.

[0004] To achieve the above objectives, one embodiment of this utility model provides a wear-resistant and explosion-proof boiler water-cooled wall tube, including two retainers. A pipe body is disposed in the middle of the adjacent sides of the two retainers. Each of the two retainers has a retaining groove on the side near the inner wall of the pipe body. A rubber pad is disposed inside each of the two retaining grooves. Two limiting grooves are disposed on one side of one retainer, and a first limiting post that cooperates with the two limiting grooves is disposed on one side of the other retainer. An installation groove is disposed at the top of each of the two retainers. An arc-shaped groove is disposed on the bottom wall of each of the two installation grooves. A placement groove is disposed at the end of each of the two arc-shaped grooves that are close to each other. A retaining block is slidably connected inside the two arc-shaped grooves. A limiting block that can move up and down is disposed inside the two installation grooves. The middle of the limiting block is slidably connected to the retaining block.

[0005] Preferably, the outer surfaces of the two rubber pads are stepped, which makes it easier for the outer surfaces of the two rubber pads to bulge outwards. By cooperating with the two slots, the two rubber pads can be easily positioned to prevent them from separating from the two slots due to vibration.

[0006] Preferably, the longitudinal sections of the two arc-shaped grooves are T-shaped, and the circumferential centers of the two arc-shaped grooves coincide. This design facilitates the limiting and guiding of the locking blocks, thereby allowing the two locking seats to contact each other, stabilizing their relative positions, and making it easier for the user to fix the two locking seats to the external boiler using bolts.

[0007] Preferably, in any of the above solutions, the width of both placement slots is greater than the width of the card block.

[0008] Preferably, the top surface of the card block is arc-shaped, and both ends of the card block are T-shaped. This design provides an operating position for the user to rotate the card block. At the same time, by slidingly connecting with the limiting block, the installation position of the card block is limited, thereby limiting the two card seats and clamping the pipe body.

[0009] Preferably, in any of the above solutions, limit holes are provided at both corners of the bottom walls of the two mounting slots, and second limit posts that cooperate with the limit holes are provided at the four corners of the bottom surface of the limit block. By using this solution, it is convenient to limit the installation of the limit block. At the same time, when the limit block enters the interior of the two mounting slots, it is convenient to limit the two card holders and card blocks, and stabilize the relative position of the two card holders.

[0010] Preferably, both sides of the limiting block are fixedly connected to protrusions.

[0011] This utility model has the following advantages:

[0012] 1. This wear-resistant and explosion-proof boiler water-cooled wall tube is equipped with two retaining seats, two limiting grooves, and two first limiting posts. The two first limiting posts are slidably connected to the two limiting grooves, thereby securing the two retaining seats to the outer wall of the pipe body. By setting two rubber pads, the pipe body is isolated from the two retaining seats, providing buffering and protection for the pipe body and preventing it from bursting due to wear. The two retaining seats are fixed to the external boiler by bolts. The bolts securing the two retaining seats can be removed, the limiting blocks can be pulled out to expose the retaining blocks, and the retaining blocks can be rotated to rotate into the two placement grooves and pulled out, thus facilitating the quick disassembly of the two retaining seats and effectively solving the problems existing in the prior art.

[0013] 2. This wear-resistant and explosion-proof boiler water-cooled wall tube is equipped with a locking block and a limiting block. The locking block is slidably connected to two arc-shaped grooves, and the four second limiting posts are slidably connected to four limiting holes, which facilitates the limiting of the two locking seats and prevents the locking block from rotating on its own, ensuring the safety of the overall structure. At the same time, the overall structure is simple and easy for users to install and use.

[0014] 3. This wear-resistant and explosion-proof boiler water-cooled wall tube features two rubber pads, each with a stepped outer surface. The two rubber pads engage with two slots, facilitating their positioning. Compared to traditional circular rubber pads, this design prevents the rubber pads from separating from the slots due to vibration, and also makes installation easier for the user.

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0024] like Figures 1 to 7 As shown, a wear-resistant and explosion-proof boiler water-cooled wall tube includes two mounting bases 1. A pipe body 5 is disposed in the middle of the adjacent sides of the two mounting bases 1. Each mounting base 1 has a groove 13 on the side near the inner wall of the pipe body 5. A rubber pad 4 is disposed inside the groove 13. Two limiting grooves 12 are disposed on one side of one mounting base 1. A first limiting post 6 that cooperates with the two limiting grooves 12 is disposed on one side of the other mounting base 1. An installation groove 10 is disposed at the top of each mounting base 1. An arc-shaped groove 11 is disposed on the bottom wall of each installation groove 10. A placement groove 7 is disposed at the end of each arc-shaped groove 11 that is close to each other. A locking block 9 is slidably connected inside the arc-shaped groove 11. A limiting block 2 that can move up and down is disposed inside the installation groove 10. The middle part of the limiting block 2 is slidably connected to the locking block 9.

[0025] The outer surfaces of the two rubber pads 4 are stepped. As an optional technical solution of this utility model, this makes it easy for the outer surfaces of the two rubber pads 4 to bulge outward. By cooperating with the two slots 13, it is easy to limit the two rubber pads 4 and prevent the two rubber pads 4 from separating from the two slots 1 due to vibration.

[0026] The longitudinal section of the two arc-shaped grooves 11 is T-shaped, and the circumferential centers of the two arc-shaped grooves 11 coincide. As an optional technical solution of this utility model, this facilitates the limiting and guiding of the card block 9, thereby making the two card seats 1 contact each other, stabilizing the relative position of the two card seats 1, and making it convenient for the user to fix the two card seats 1 to the external boiler with bolts.

[0027] The width of both placement slots 7 is greater than the width of the card block 9. As an optional technical solution of this utility model, this makes it easier for the card holder 9 to smoothly enter and exit the two placement slots 7, thereby facilitating the user to install and disassemble the two card holders 9.

[0028] The top surface of the card block 9 is arc-shaped, and both ends of the card block 9 are T-shaped. As an optional technical solution of this utility model, this facilitates the user to rotate the card block 9 and provides an operating position. At the same time, by slidingly connecting with the limiting block 2, the installation position of the card block 9 is limited, thereby limiting the two card seats 1 and clamping the pipe body 5.

[0029] Limiting holes 8 are provided at the two corners of the bottom wall of the two mounting slots 10, and second limiting posts 14 that cooperate with the limiting holes 8 are provided at the four corners of the bottom surface of the limiting block 2. As an optional technical solution of this utility model, this facilitates the installation of the limiting block 2 and, when the limiting block 2 enters the interior of the two mounting slots 10, it facilitates the limiting of the two card seats 1 and the card block 9, and stabilizes the relative position of the two card seats 1.

[0030] Both sides of the limiting block 2 are fixedly connected with protrusions 3. As an optional technical solution of this utility model, this makes it easy for the user to pinch the limiting block 2 through the two protrusions 3, which facilitates the initial installation and subsequent disassembly of the limiting block 2.

[0031] This type of wear-resistant and explosion-proof boiler water-cooled wall tube requires the following steps when used:

[0032] 1) During disassembly, remove the bolts that fix the two card holders 1, rotate the two card holders 1 to move the limiting block 2 away from the inner wall of the boiler;

[0033] 2) Pull the limiting block 2 outward through the two protrusions 3 to expose the locking block 9;

[0034] 3) Rotate the locking block 9 so that it rotates into the two placement slots 7 and is pulled out, thereby separating the two card holders 1 and completing the purpose of quick disassembly.

[0035] In summary, during use, the system employs two retaining seats 1, two limiting grooves 12, and two first limiting posts 6. The two first limiting posts 6 are slidably connected to the two limiting grooves 12, thereby securing the two retaining seats 1 against the outer wall of the pipe body 5. Two rubber pads 4 are provided to isolate the pipe body 5 from the two retaining seats 1, providing cushioning and protection to prevent the pipe body 5 from bursting due to wear. The two retaining seats 1 are fixed to an external boiler by bolts. Removing these bolts allows the limiting blocks 2 to be pulled outwards, exposing the retaining blocks 9. Rotating the retaining blocks 9 into the two placement grooves 7 and pulling them out facilitates quick disassembly of the two retaining seats 1, effectively solving the problems of existing technologies. To address the problems encountered during the procedure, a locking block 9 and a limiting block 2 are installed. The locking block 9 is slidably connected to two arc-shaped grooves 11, while the four second limiting posts 14 are slidably connected to four limiting holes 8. This facilitates the limiting of the two card seats 1 and prevents the locking block 9 from rotating, ensuring the safety of the overall structure. The overall structure is simple and easy for users to install and use. Finally, two rubber pads 4 are installed, with the outer circular surface of each rubber pad 4 being stepped. The two rubber pads 4 cooperate with the two card grooves 13, facilitating the limiting of the two rubber pads 4. Compared to traditional circular rubber pads, this prevents the two rubber pads 4 from separating from the two card seats 1 due to vibration, and also makes installation easier for users.
