Description

Technical Field

[0001] This utility model relates to the technical field of boiler protective components, and more specifically, to a wear-resistant tile that prevents boiler tubes from falling off easily. Background Technology

[0002] Wear-resistant tiles, also known as wear-resistant covers, wear-resistant plates, wear-resistant protective tiles, wear-resistant cover plates, corrosion-resistant cover plates, boiler climbing pipes, wear-resistant pressure plates, etc., are commonly used accessories for boiler tubes in power plants. They are mainly used to protect the air-receiving surface of boiler tubes, reduce pipe wear, and increase the service life of the heated surface tubes.

[0003] Currently, wear-resistant tiles are usually fixed to the air-receiving surface of boiler tubes using clips or clamps. However, during the use of boiler tubes, the temperature difference varies greatly, resulting in significant thermal expansion and contraction. This can easily cause the wear-resistant tiles, which are fixed by clamps, to loosen on the boiler tubes. Consequently, the wear-resistant tiles may rotate and shift on the boiler tubes, eventually detaching from the air-receiving surface of the boiler tubes. This results in the wear-resistant tiles losing their protective effect on the air-receiving surface of the boiler tubes. Therefore, we propose a wear-resistant tile that is less prone to detachment from boiler tubes. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a wear-resistant tile that is not easy to fall off boiler tubes, so as to solve the technical problem that wear-resistant tiles are easy to fall off from the wind-receiving surface of boiler tubes during the current use.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a wear-resistant tile for boiler tubes that is not easy to fall off, comprising a wear-resistant tile body, wherein a number of sets of hoop structures are movably installed on the open side of the wear-resistant tile body, the hoop structure includes a semi-circular ring, the two ends of the semi-circular ring are provided with fixed structures, the inner wall of the semi-circular ring is provided with a number of equidistant elastic structures, and the elastic structure is provided with a top fitting plate on the side facing the wear-resistant tile body;

[0006] The top-fitting plate includes a rectangular block, a first top-fitting block is movably arranged in the center of one side of the rectangular block, and a second top-fitting block is slidably arranged on the top and bottom of the rectangular block toward the side of the first top-fitting block, and the second top-fitting block is slidably connected to the first top-fitting block.

[0007] The hoop structure of this utility model, through a semi-circular ring, an elastic structure, and top-fitting plates, allows for efficient installation of the wear-resistant tile body. The wear-resistant tile body is secured to the air-receiving side of the boiler tube, and then the semi-circular ring is secured to the other side of the boiler tube and connected to the wear-resistant tile body. At this point, several sets of top-fitting plates inside the semi-circular ring, with the cooperation of the elastic structure, firmly press against the boiler tube, thus fixing the wear-resistant tile body. The top-fitting plates, with the cooperation of the elastic structure, provide a certain degree of cushioning. Therefore, during boiler tube use, the wear-resistant tile body and the hoop structure can better adapt to thermal expansion and contraction, ensuring that the top-fitting plates and the wear-resistant tile body are firmly fixed to the boiler tube, preventing the wear-resistant tile body from loosening. This effectively prevents the wear-resistant tile body from rotating on the boiler tube. The phenomenon of the wear-resistant tile body falling off the air-receiving surface of the boiler tube occurs. The top-fitting plate of this utility model is composed of a rectangular block, a first top-fitting block, and a second top-fitting block. Therefore, after the semicircular ring is connected to the wear-resistant tile body, the first top-fitting block will move towards the rectangular block under the push of the boiler tube. At this time, the first inclined surface of the first top-fitting block and the second inclined surface of the second top-fitting block will cooperate to push the two sets of second top-fitting blocks above and below the first top-fitting block outward until the first top-fitting block and the second top-fitting block are aligned. At this time, several sets of top-fitting plates that have been opened up inside the semicircular ring will connect with each other to form a continuous semicircular arc surface. Then the semicircular arc surface will be used to top-fit ​​the boiler tube, which can greatly increase the area of ​​top-fitting the boiler tube and further ensure the stable effect of the top-fitting plate and the elastic structure in buffering and fixing the boiler tube.

[0008] Preferably, the wear-resistant tile body has several sets of equidistant dovetail grooves inside, and rubber strips are arranged inside the dovetail grooves, with the surface of the rubber strips being corrugated.

[0009] Preferably, the fixing structure includes a fixing bolt, which is screwed onto a semi-circular ring. A mounting plate is arranged on the fixing bolt, and fixing rods are arranged at both ends of the bottom of the mounting plate, with the fixing rods penetrating the semi-circular ring.

[0010] Preferably, the top and bottom of the wear-resistant tile body are provided with mounting planes, the center of the mounting plane is provided with a fixing screw hole corresponding to the fixing bolt, and the surface of the mounting plane is provided with a fixing insertion hole corresponding to the fixing insertion rod.

[0011] Preferably, the elastic structure includes a concave frame that is arranged through the semicircular ring, with springs fitted at both ends of the concave frame, and the concave frame is connected to a rectangular block at both ends of the semicircular ring.

[0012] Preferably, the rectangular block has two sets of first T-shaped grooves symmetrically arranged on the side facing the first top block, and the second top block has two sets of second T-shaped strips symmetrically arranged on the side facing the rectangular block, with the second T-shaped strips inserted into the first T-shaped grooves.

[0013] Preferably, the rectangular block has a rectangular hole in the center, and the rectangular hole opens to the side of the first T-slot in a flared shape. The first top fitting block is divided into a top fitting part, a connecting part and a T-shaped insert. The T-shaped insert passes through the rectangular hole, and the first inclined surface matches the flared size.

[0014] Preferably, the top and bottom of the top fitting part and the connecting part are first inclined surfaces, two sets of symmetrical second T-shaped grooves are provided on the first inclined surface, and a first T-shaped strip is slidably arranged inside the second T-shaped groove. The second top fitting block faces the first top fitting block and is a second inclined surface. The second inclined surface matches and connects with the first inclined surface, and the first T-shaped strip is connected to the second inclined surface.

[0015] Preferably, the top fitting part and the second top fitting block have an arc surface facing away from the rectangular block, the arc surface matches the arc surface of the boiler tube, and the arc surface of the top fitting part and the second top fitting block is provided with anti-slip texture.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The hoop structure of this utility model, through a semi-circular ring, an elastic structure, and top-fitting plates, allows for precise installation of the wear-resistant tile body. The wear-resistant tile body is secured to the air-receiving surface of the boiler tube, and then the semi-circular ring is secured to the other side of the boiler tube and connected to the wear-resistant tile body. At this time, several sets of top-fitting plates inside the semi-circular ring are firmly fixed to the boiler tube with the cooperation of the elastic structure, thus achieving the fixation of the wear-resistant tile body. The top-fitting plates, with the cooperation of the elastic structure, possess a certain buffering performance. Therefore, during the use of the boiler tube, the wear-resistant tile body and the hoop structure can better adapt to thermal expansion and contraction, ensuring that the top-fitting plates and the wear-resistant tile body are firmly fixed to the boiler tube, preventing the wear-resistant tile body from loosening. This effectively prevents the wear-resistant tile body from rotating on the boiler tube, thus avoiding the phenomenon of the wear-resistant tile body detaching from the air-receiving surface of the boiler tube. This solves the technical problem of current wear-resistant tiles easily detaching from the air-receiving surface of the boiler tube during use. Therefore, this utility model has the advantage of providing more stable protection for the air-receiving surface of the boiler tube.

[0018] 2. The top-fitting plate of this utility model is composed of a rectangular block, a first top-fitting block, and a second top-fitting block. Therefore, after the semicircular ring is connected to the wear-resistant tile body, the first top-fitting block will move towards the rectangular block due to the push of the boiler tube. At this time, with the cooperation of the first inclined surface of the first top-fitting block and the second inclined surface of the second top-fitting block, the two sets of second top-fitting blocks above and below the first top-fitting block will be pushed outward until the first top-fitting block and the second top-fitting block are aligned. At this time, several sets of top-fitting plates that have been spread out inside the semicircular ring will connect with each other to form a continuous semicircular arc surface. Then, the semicircular arc surface will top-fit ​​the boiler tube, which can greatly increase the area of ​​top-fitting the boiler tube and further ensure the stable effect of the top-fitting plate and the elastic structure in buffering and fixing the boiler tube.

[0028] like Figures 1 to 7 As shown, the present invention relates to a wear-resistant and wear-resistant anti-wear tile for boiler tubes that is not easy to fall off, comprising an anti-wear tile body 1, several sets of hoop structures 2 are movably installed on the open side of the anti-wear tile body 1, the hoop structure 2 includes a semi-circular ring 3, the two ends of the semi-circular ring 3 are provided with fixing structures 9, several sets of equidistant elastic structures 4 are arranged on the inner wall of the semi-circular ring 3, and a top fitting plate 5 is arranged on the side of the elastic structure 4 facing the anti-wear tile body 1.

[0029] During the installation of the wear-resistant tile body 1, the wear-resistant tile body 1 is snapped onto the air-receiving side of the boiler tube, and then the semi-circular ring 3 is snapped onto the other side of the boiler tube. Then, it is connected to the wear-resistant tile body 1 through the fixing structure 9. At this time, several sets of top fitting plates 5 inside the semi-circular ring 3 are firmly fixed to the boiler tube with the cooperation of the elastic structure 4, thereby fixing the wear-resistant tile body 1. At this time, the top fitting plates 5 have a certain buffering performance with the cooperation of the elastic structure 4. Therefore, during the use of the boiler tube, the wear-resistant tile body 1 and the hoop structure 2 can better adapt to thermal expansion and contraction, ensuring that the top fitting plates 5 and the wear-resistant tile body 1 can be firmly fixed to the boiler tube, and the wear-resistant tile body 1 will not loosen. Therefore, it can effectively prevent the wear-resistant tile body 1 from rotating on the boiler tube, causing the wear-resistant tile body 1 to fall off from the air-receiving side of the boiler tube.

[0030] Specifically, the wear-resistant tile body 1 has several sets of equidistant dovetail grooves 101 inside, and rubber strips 102 are arranged inside the dovetail grooves 101. The surface of the rubber strips 102 is corrugated. When the wear-resistant tile body 1 is pressed onto the air-receiving surface of the boiler tube, the rubber strips 102 are deformed by the pressure and fill the dovetail grooves 101. Then the rubber strips 102 can be firmly fixed in the dovetail grooves 101 and will not fall off. Then the rubber strips 102, together with their corrugations, can be firmly fixed on the boiler tube and can also adapt to thermal expansion and contraction to a certain extent.

[0031] Furthermore, the fixing structure 9 includes a fixing bolt 901, which is screwed onto the semi-circular ring 3. A mounting plate 902 is arranged on the fixing bolt 901, and fixing rods 903 are arranged at both ends of the bottom of the mounting plate 902, with the fixing rods 903 penetrating the semi-circular ring 3. The top and bottom of the wear-resistant tile body 1 are provided with mounting surfaces 103. A fixing screw hole 104 corresponding to the fixing bolt 901 is opened in the center of the mounting surface 103, and a fixing rod 903 is opened on the surface of the mounting surface 103. When the semicircular ring 3 is connected and installed with the anti-wear tile body 1, the two ends of the semicircular ring 3 are overlapped on the mounting plane 103. Then, the two sets of fixing rods 903 on the mounting plate 902 are inserted into the fixing hole 105, and then the fixing bolts 901 are screwed in. The fixing bolts 901 pass through the mounting plate 902 and the semicircular ring 3 in sequence. Then, the fixing bolts 901 are screwed into the fixing screw hole 104, thereby realizing the connection and installation of the semicircular ring 3 and the anti-wear tile body 1.

[0032] Furthermore, the elastic structure 4 includes a concave frame 401, which is arranged through the semi-circular ring 3. Springs 402 are sleeved at both ends of the concave frame 401, and the concave frame 401 is connected to the rectangular block 6 through both ends of the semi-circular ring 3. The concave frame 401 is used to limit the displacement direction of the top plate 5, and the springs 402 can make the top plate 5 have extensibility. Therefore, when the top plate 5 is pressed against the boiler tube, the top plate 5 has a certain degree of extensibility, so as to adapt to the situation of thermal expansion and contraction.

[0033] In an embodiment of this utility model, the top fitting plate 5 includes a rectangular block 6, a first top fitting block 7 is movably arranged in the center of one side of the rectangular block 6, and a second top fitting block 8 is slidably arranged on the top and bottom of the rectangular block 6 facing the first top fitting block 7, and the second top fitting block 8 is slidably connected to the first top fitting block 7; the top and bottom of the top fitting part 701 and the connecting part 702 are first inclined surfaces 703, two sets of symmetrical second T-shaped grooves 705 are opened on the first inclined surface 703, and a first T-shaped strip 706 is slidably arranged inside the second T-shaped groove 705; the second top fitting block 8 is a second inclined surface 802 facing the first top fitting block 7, the second inclined surface 802 matches and connects with the first inclined surface 703, and the first T-shaped strip 706 is connected to the second inclined surface 802;

[0034] After the semicircular ring 3 is connected to the wear-resistant tile body 1, the first top-fitting block 7 will move towards the rectangular block 6 due to the push of the boiler tube. At this time, with the cooperation of the first inclined surface 703 of the first top-fitting block 7 and the second inclined surface 802 of the second top-fitting block 8, the upper and lower sets of second top-fitting blocks 8 of the first top-fitting block 7 will be pushed outward until the first top-fitting block 7 and the second top-fitting block 8 are aligned. At this time, several sets of top-fitting plates 5 that have been opened up inside the semicircular ring 3 will be connected to each other to form a continuous semicircular arc surface. Then the semicircular arc surface will be used to top-fit ​​the boiler tube, which can greatly increase the area of ​​top-fitting the boiler tube and further ensure the stable effect of the top-fitting plate 5 and the elastic structure 4 in buffering and fixing the boiler tube.

[0035] Specifically, the rectangular block 6 has two sets of first T-slots 601 symmetrically arranged on the side facing the first top block 7, and the second top block 8 has two sets of second T-slots 801 symmetrically arranged on the side facing the rectangular block 6. The second T-slots 801 are inserted into the first T-slots 601. With the cooperation of the first T-slots 601 and the second T-slots 801, the second top block 8 is slidably installed on the rectangular block 6.

[0036] Furthermore, a rectangular hole 603 is provided in the center of the rectangular block 6, and the rectangular hole 603 opens into a flared opening 602 facing the first T-shaped groove 601. The first top fitting block 7 is divided into a top fitting part 701, a connecting part 702, and a T-shaped insert 704. The T-shaped insert 704 passes through the rectangular hole 603, and the first inclined surface 703 matches the size of the flared opening 602. The T-shaped insert 704 and the connecting part 702 can move in the rectangular hole 603 and the flared opening 602, thereby realizing the sliding installation of the first top fitting block 7 on the rectangular block 6.

[0037] Furthermore, the top fitting part 701 and the second top fitting block 8 have an arc surface facing away from the rectangular block 6. The arc surface matches the arc surface of the boiler tube, and the arc surfaces of the top fitting part 701 and the second top fitting block 8 are provided with anti-slip textures. The arc surfaces of the top fitting part 701 and the second top fitting block 8 can fit and secure the arc surface of the boiler tube. The anti-slip textures are used to increase the stability of the arc surfaces of the top fitting part 701 and the second top fitting block 8 fitting on the boiler tube.

[0038] Working Principle: This embodiment provides a wear-resistant tile that is not easy to fall off boiler tubes. First, when installing the wear-resistant tile body 1, the wear-resistant tile body 1 is snapped onto the air-receiving side of the boiler tube. Then, the semi-circular ring 3 is snapped onto the other side of the boiler tube. Then, it is connected to the wear-resistant tile body 1 through the fixing structure 9. At this time, several sets of top-fitting plates 5 inside the semi-circular ring 3 are firmly fixed onto the boiler tube with the cooperation of the elastic structure 4, thereby fixing the wear-resistant tile body 1. At this time, the top-fitting plates 5 have a certain buffering performance with the cooperation of the elastic structure 4. Therefore, during the use of the boiler tube, the wear-resistant tile body 1 and the hoop structure 2 can better adapt to thermal expansion and contraction, ensuring that the top-fitting plates 5 and the wear-resistant tile body 1 can be firmly fixed on the boiler tube. The wear-resistant tile body 1 will not loosen. Therefore, it can effectively prevent the wear-resistant tile body 1 from rotating on the boiler tube, causing the wear-resistant tile body 1 to fall off from the air-receiving side of the boiler tube.

[0039] Secondly, after the semicircular ring 3 is connected to the wear-resistant tile body 1, the first top-fitting block 7 will move towards the rectangular block 6 due to the push of the boiler tube. At this time, with the cooperation of the first inclined surface 703 of the first top-fitting block 7 and the second inclined surface 802 of the second top-fitting block 8, the upper and lower sets of second top-fitting blocks 8 of the first top-fitting block 7 will be pushed outward until the first top-fitting block 7 and the second top-fitting block 8 are aligned. At this time, several sets of top-fitting plates 5 that have been opened up inside the semicircular ring 3 will be connected to each other to form a continuous semicircular arc surface. Then the semicircular arc surface will be used to top-fit ​​the boiler tube, which can greatly increase the area of ​​the boiler tube top-fitting and further ensure the stable effect of the top-fitting plate 5 and the elastic structure 4 in buffering and fixing the boiler tube.
