[0002] Elevated steam pipelines are supported by auxiliary tower brackets that run along the side of the tower, with the brackets fixed to the tower's crossbars. Traditionally, those skilled in the art have used extensively welded pipe supports to support steam pipelines, with bolts used only for localized reinforcement. However, traditional steam pipeline support assemblies have strict dimensional requirements for their guide and limiting components, making on-site construction quality difficult to guarantee, resulting in significant installation deviations, large amounts of welding at height, high-altitude work difficulty, high labor costs, and difficulty in disassembly during maintenance. To address these issues, a new type of detachable pipe support has been developed, increasing the reliability of the support structure, reducing the difficulty of high-altitude work, improving the standardization of design and operation, and possessing a detachable function.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] like Figure 1-4 As shown, this utility model provides two arc-shaped pads 2, the inner curvature of which is completely consistent with the radius of curvature of the outer edge of the supporting crossbar 1, ensuring that the arc-shaped pads 2 can fit tightly against the supporting crossbar 1. In the actual welding process, a full welding method is adopted to weld the arc-shaped pads 2 to the preset position of the supporting crossbar 1. The welding height is not less than the thickness of the arc-shaped pads 2, and the welding length covers the entire edge of the arc-shaped pads 2 in contact with the supporting crossbar 1, so as to ensure the firmness and stability of the connection between the two, and effectively bear the weight of subsequent components and steam pipes. H-beams 3 are welded onto two curved pads 2, with the lower flange of the H-beam 3 completely flush with the upper surface of the curved pads 2. During welding, the H-beams 3 are first precisely positioned to ensure they are symmetrically distributed along the axis of the supporting crossbar 1, and that the centerline of the H-beam 3 coincides with the centerline of the curved pads 2. After positioning, double-sided welding is performed. The weld must be uniform, continuous, and free of slag inclusions, porosity, or other welding defects. The weld strength must meet the load-bearing requirements, ensuring that the H-beams 3 and the curved pads 2 form a stable overall structure, providing a reliable support foundation for the subsequent installation of the lower base plate 4. The lower base plate 4 is welded to the middle of the H-beam steel plate 3, with its lower surface tightly fitted to the upper surface of the upper flange of the H-beam steel plate 3. Before welding, the specific position of the lower base plate 4 on the H-beam steel plate 3 needs to be determined according to the actual installation requirements, ensuring that the centerline of the lower base plate 4 coincides with the centerline of the H-beam steel plate 3 to ensure balanced stress distribution throughout the pipe support structure. During welding, a perimeter welding method is used to weld and fix the lower base plate 4 to the upper flange of the H-beam steel plate 3. The height and length of the weld seam need to be reasonably designed according to the thickness and dimensions of the lower base plate 4 to ensure the connection strength between the two, which can withstand the load transmitted by components such as the sliding member 6, the support plate 7, the pipe clamp 9, and the steam pipe. The sliding member 6 is slidably installed in the sliding groove 5, and the sliding member 6 and the sliding groove 5 are in clearance fit as described in claim 2. The sliding groove 5 has a U-shaped structure, with its opening facing the axis of the supporting crossbar 1. The bottom of the sliding groove 5 is fixedly connected to the lower base plate 4 by welding. During welding, the verticality of the sliding groove 5 must be ensured to avoid the sliding component 6 from sliding poorly due to tilting. The external dimensions of the sliding component 6 match the internal cavity dimensions of the sliding groove 5, and the fit clearance between them is controlled within the range of 0.5-1.5mm. This clearance size can ensure that the sliding component 6 slides smoothly in the sliding groove 5 to accommodate the displacement caused by the thermal expansion and contraction of the steam pipe, and can also effectively limit the displacement of the sliding component 6 in the direction perpendicular to the sliding direction to prevent the sliding component 6 from deviating or shaking, thus ensuring the guiding accuracy of the pipe support. Furthermore, to reduce the frictional resistance between the sliding component 6 and the sliding groove 5, wear-resistant grease can be applied to the contact surfaces of the sliding component 6 and the sliding groove 5. The type of wear-resistant grease can be selected according to the operating temperature and load conditions of the pipe support. Generally, high-temperature resistant and wear-resistant grease, such as lithium molybdenum disulfide grease, is selected to improve the sliding performance and service life of the sliding component 6. At the same time, buffer blocks are provided at both ends of the sliding groove 5. The buffer blocks are made of elastic materials, such as rubber or polyurethane. When the sliding component 6 slides to the end of the sliding groove 5 due to the thermal expansion and contraction of the pipe, the buffer blocks can play a role in buffering and shock absorption, preventing the sliding component 6 from directly colliding with the sliding groove 5 and causing damage. A support plate 7 is installed on the upper end of the sliding member 6, and the lower end of the support plate 7 is fixedly connected to the upper end face of the sliding member 6 by welding. Before welding, the position of the support plate 7 needs to be accurately positioned to ensure that the support plate 7 is perpendicular to the upper end face of the sliding member 6, and that the two support plates 7 are vertically and symmetrically welded to both sides of the center line of the pipe clamp 9 as described in claim 7. During welding, a bevel welding method is used. The angle and depth of the weld bevel are designed according to the thickness of the support plate 7. Generally, the bevel angle is 30°-60°, and the depth is 1 / 2-2 / 3 of the thickness of the support plate 7 to ensure the strength of the weld joint. After welding, the weld joint needs to be subjected to non-destructive testing, such as ultrasonic testing, to ensure that the welding quality is defect-free, so that a firm connection is formed between the support plate 7 and the sliding member 6, which can reliably support the weight of the pipe clamp 9 and the steam pipe. Furthermore, the support plate 7 is a trapezoidal or rectangular plate with a thickness of not less than 14mm, as described in claim 7. When a trapezoidal plate is used, the length of the upper base of the trapezoidal plate matches the width of the lower surface of the pipe clamp 9, and the length of the lower base matches the width of the upper end face of the sliding member 6. The waist height of the trapezoidal plate is determined according to the actual support height requirements. When a rectangular plate is used, the length and width of the rectangular plate are adapted to the upper end face dimensions of the sliding member 6 and the lower surface dimensions of the pipe clamp 9, respectively, to ensure sufficient contact area between the support plate 7, the pipe clamp 9, and the sliding member 6, thereby improving the stability of the support. A pipe clamp 9 is installed on the upper end of the support plate 7, with its lower surface tightly fitted against the upper surface of the support plate 7. The pipe clamp 9 and the support plate 7 are fixedly connected by welding. During welding, spot welding is first performed at the contact point between the lower surface of the pipe clamp 9 and the upper surface of the support plate 7 to ensure that the centerline of the pipe clamp 9 coincides with the centerline of the support plate 7, and that the axial direction of the pipe clamp 9 is consistent with the axial direction of the steam pipe. After positioning, continuous welding is used to weld the pipe clamp 9 and the support plate 7 together. The weld seam must be evenly distributed around the upper surface of the support plate 7, and the weld strength must meet the requirements for the pipe clamp 9 to hold the steam pipe, preventing the pipe clamp 9 from loosening or falling off during use. The pipe clamp 9 has a split upper and lower structure, and the left and right sections of the two split pipe clamps 9 are fixed by bolts 10 as described in claim 3. The split upper and lower structure design facilitates the clamping and disassembly of the working steel pipe 11 by the pipe clamp 9. When installing the working steel pipe 11, first fix the lower pipe clamp on the support plate 7, then place the working steel pipe 11 in the arc-shaped groove of the lower pipe clamp, then cover it with the upper pipe clamp, and finally fix the left and right sections of the upper and lower pipe clamps together by bolts 10. The inner curvature of the arc-shaped groove of the upper and lower pipe clamps matches the outer edge curvature radius of the working steel pipe 11, ensuring that the pipe clamp 9 can fit tightly with the working steel pipe 11 and improving the stability of clamping. As described in claim 4, heat-insulating tiles 8 are installed inside the two pipe clamps 9. The external dimensions of the heat-insulating tiles 8 are adapted to the internal cavity dimensions of the pipe clamps 9, ensuring that the heat-insulating tiles 8 can tightly fill the gap between the pipe clamps 9 and the working steel pipe 11. When installing the heat-insulating tiles 8, first place the heat-insulating tiles 8 in the lower pipe clamp into position, then place the working steel pipe 11 on the heat-insulating tiles 8, then cover the upper surface of the working steel pipe 11 with the heat-insulating tiles 8 in the upper pipe clamp, and finally cover the upper pipe clamp and fix it with bolts 10. The installation of heat-insulating tiles 8 can effectively block the heat of high-temperature steam in the working steel pipe 11 from being transferred to the support structure through the pipe clamps 9, reducing heat loss, while protecting the support structure from high temperature and extending its service life. Furthermore, a soft insulation layer 13 is provided on the inner wall of the heat insulation tile 8 as described in claim 4. The soft insulation layer 13 is made of a high-temperature resistant soft insulation material, such as ceramic fiber cotton or glass fiber cotton, and its thickness is generally 5-10 mm. The soft insulation layer 13 is adhered to the inner wall of the heat insulation tile 8 with a high-temperature adhesive. The adhesive must be applied evenly to ensure a firm bond between the soft insulation layer 13 and the heat insulation tile 8, without any detachment. The soft insulation layer 13 not only further improves the heat insulation effect but also acts as a buffer, preventing damage caused by rigid contact between the working steel pipe 11 and the heat insulation tile 8, while also accommodating slight vibrations of the working steel pipe 11 during operation. At least two sets of reinforcing ribs 12 are evenly arranged inside the heat insulation tile 8. Each set of reinforcing ribs 12 consists of four threaded steel bars, which are centrally symmetrically distributed inside the heat insulation tile 8. Both ends of the threaded steel bars are welded and fixed to the inner wall of the pipe clamp 9 as described in claim 5. The setting of the reinforcing ribs 12 can effectively improve the structural strength and compressive strength of the heat insulation tile 8, and prevent the heat insulation tile 8 from cracking or being damaged due to stress during long-term use. When manufacturing the heat insulation tile 8, the threaded steel bars are first fixed according to the designed position and distribution. Then, heat insulation materials, such as high-temperature resistant ceramic heat insulation materials or composite silicate heat insulation materials, are poured around the threaded steel bars. After the heat insulation material has cured and formed, a heat insulation tile 8 with reinforcing ribs 12 is formed. The two ends of the threaded steel bars extend beyond the end face of the heat insulation tile 8, with an extension length of generally 10-15mm, to facilitate welding to the inner wall of the pipe clamp 9. During welding, the extended ends of the threaded steel bars are fixed to the inner wall of the pipe clamp 9 by spot welding. The welding points must be firm and reliable to ensure that the reinforcing ribs 12 can effectively connect the heat insulation tile 8 and the pipe clamp 9 into a whole, further improving the connection stability between the pipe clamp 9 and the heat insulation tile 8. Furthermore, the diameter of the threaded steel bar is φ4-φ12mm, and the vertical distance between the center of the threaded steel bar and the edge of the pipe clamp 9 is 20-30mm. The pipe clamp 9 is made of thickened steel plate with a thickness of 6-14mm, as described in claim 6. The selection of the diameter of the threaded steel bar needs to be determined according to the size and load-bearing requirements of the heat insulation tile 8. Generally, for heat insulation tiles 8 with larger size or heavier load, a larger diameter threaded steel bar is selected; conversely, a smaller diameter threaded steel bar is selected. The vertical distance between the center of the threaded steel bar and the edge of the pipe clamp 9 is set within the range of 20-30mm, which can ensure the supporting effect of the reinforcing bar 12 on the heat insulation tile 8, and also avoid the threaded steel bar being too close to the edge of the pipe clamp 9, thus affecting the structural strength of the pipe clamp 9. The pipe clamp 9 is made of thickened steel plate with a thickness of 6-14mm, which can improve the load-bearing capacity and service life of the pipe clamp 9, and ensure that it can reliably clamp the working steel pipe 11. A circular groove 101 is formed at the bottom end of the bolt body 10, and a bolt shank 103 is installed at the bottom end of the circular groove 101 as described in claim 8. The inner diameter of the circular groove 101 matches the outer diameter of the bolt shank 103. The upper end of the bolt shank 103 is installed at the bottom end of the circular groove 101 by a threaded connection. The thread profile is a triangular thread with a thread accuracy grade of 6H / 6g to ensure the reliability and sealing of the connection between the bolt shank 103 and the bolt body 10. During installation, thread sealant needs to be applied to the threaded connection to prevent the bolt shank 103 from loosening due to vibration during use, and also to provide a sealing effect to prevent external impurities from entering the threaded connection. A rubber pad 109 is installed at the end of the bolt shank 103 as described in claim 8. The rubber pad 109 is made of high-temperature resistant and aging-resistant rubber material, such as silicone rubber or fluororubber, and its thickness is generally 3-5 mm, with a diameter slightly larger than that of the bolt shank 103. The rubber pad 109 is adhered to the end of the bolt shank 103 by an adhesive. The adhesive must have good high-temperature resistance and bonding strength to ensure a firm bond between the rubber pad 109 and the bolt shank 103. The rubber pad 109 prevents the end of the bolt shank 103 from directly contacting the pipe clamp 9 or the working steel pipe 11 during the tightening of the bolt 10, thus providing a buffering and protective function. It also improves the sealing of the bolt 10 connection, preventing external dust, moisture, and other impurities from entering the pipe clamp 9. A retaining ring 106 is installed on the upper outer end of the bolt rod 103. An annular pressure plate 105, a spring 107, and an annular rubber sheet 102 are fitted onto the circumferential surface of the bolt rod 103. A compression block 104 is installed at the upper edge of the annular rubber sheet 102, as described in claim 9. The retaining ring 106 is fixed to the upper outer end of the bolt rod 103 by welding. Its function is to axially position the annular pressure plate 105, spring 107, and annular rubber sheet 102, preventing axial movement of these components during bolt 10's use. The annular pressure plate 105 is made of a metal material, such as stainless steel. Its inner diameter matches the outer diameter of the bolt rod 103, and its outer diameter is slightly smaller than the outer diameter of the annular rubber sheet 102, enabling it to evenly transmit the elastic force of the spring 107 to the annular rubber sheet 102. Spring 107 is a cylindrical helical compression spring with an inner diameter slightly larger than the outer diameter of bolt rod 103 and an outer diameter smaller than the outer diameter of annular pressure plate 105. The free length and stiffness of spring 107 are designed according to the preload requirements of bolt 10 to ensure that after bolt 10 is tightened, spring 107 can generate sufficient preload to make annular rubber plate 102 fit tightly against the surface of pipe clamp 9, thereby improving the sealing and anti-loosening performance of bolt 10 connection. The annular rubber sheet 102 is made of oil-resistant and aging-resistant rubber materials, such as nitrile rubber and EPDM rubber. Its thickness is generally 4-6 mm, and its inner diameter matches the outer diameter of the bolt shank 103, while the outer diameter is slightly larger than the diameter of the bolt hole on the pipe clamp 9. An extrusion block 104 is installed at the upper edge of the annular rubber sheet 102. The extrusion block 104 is made of metal materials, such as aluminum alloy or brass, and is annular in shape. Its inner diameter and outer diameter are the same as those of the annular rubber sheet 102, and its thickness is 2-3 mm. The extrusion block 104 is fixedly connected to the annular rubber sheet 102 by an adhesive. During the tightening of the bolt 10, the extrusion block 104 can evenly transmit the tightening force of the bolt 10 to the annular rubber sheet 102, causing the annular rubber sheet 102 to deform uniformly, thereby further improving the sealing effect. The outer wall of the bolt body 10 is provided with an arc surface 108, and the surface of the arc surface 108 is provided with anti-slip texture as claimed in claim 10. The design of the arc surface 108 can avoid sharp edges on the outer wall of the bolt body 10, preventing scratches to operators during installation and use, and also reducing collision damage to the bolt body 10 during transportation and storage. The anti-slip texture can increase the friction between the outer wall of the bolt body 10 and the operator's hand or tools, making it easier for operators to tighten or loosen the bolt 10 using tools such as wrenches, preventing tools from slipping during operation, and improving the safety and convenience of operation. The shape of the anti-slip texture can be twill, mesh, or diamond, etc. The depth of the anti-slip texture is generally 0.5-1mm, and the spacing is 1-2mm. When processing the anti-slip texture, it is necessary to ensure that the surface roughness of the anti-slip texture is uniform, without burrs, flash, or other defects, to ensure the anti-slip effect and the feel of operation. Material selection for each component: Support crossbar 1: Made of Q235B or Q355B carbon structural steel, it has high strength and toughness and can withstand the weight of the steam pipeline and the load during operation. Arc-shaped pad 2, H-shaped steel plate 3, bottom plate 4, sliding groove 5, support plate 7, and pipe clamp 9: are all made of Q355B carbon structural steel. This material has good welding performance and mechanical properties, and can meet the welding connection requirements and load-bearing requirements between various components. Sliding component 6: Made of 45 steel, it undergoes quenching and tempering treatment followed by high-temperature tempering, giving it high hardness and wear resistance, with a hardness of HRC28-32, thus improving its service life. Insulation tile 8: Made of high-temperature resistant ceramic insulation material or composite silicate insulation material, with a maximum operating temperature of not less than 600℃ and a thermal conductivity of not more than 0.1W / (m・K), it has excellent insulation performance and high temperature resistance. Reinforcing bar 12: Made of HRB400 threaded steel bar, which has high tensile strength and yield strength, effectively improving the structural strength of the heat insulation tile 8. Bolt body 10, bolt rod 103, fixing ring 106, annular pressure plate 105, and extrusion block 104 are all made of 304 stainless steel, which has good corrosion resistance and oxidation resistance, and can adapt to the outdoor environment in the case of elevated tower, preventing the components from being damaged by corrosion. Spring 107: Made of 60Si2Mn spring steel, isothermally hardened, possessing high elastic limit and fatigue strength, ensuring no permanent deformation during long-term use. Rubber Pad 109 and Annular Rubber Sheet 102: Rubber Pad 109 is made of silicone rubber, and the annular rubber sheet 102 is made of nitrile rubber. Silicone rubber has excellent high-temperature resistance and aging resistance, while nitrile rubber has good oil resistance and aging resistance, meeting the requirements of different applications. Soft Insulation Layer 13: Made of ceramic fiber cotton, with a maximum operating temperature of not less than 1000℃ and a thermal conductivity of not more than 0.03W / (m・K), possessing good insulation performance and flexibility. Installation method: Preliminary preparations 1. Based on the actual installation location and dimensions of the elevated steam pipeline, determine the installation position of the support crossbar 1, and pre-treat the support crossbar 1, such as removing rust and grinding, to remove the oxide scale and impurities on the surface and ensure welding quality. 2. Inspect each component to ensure that its dimensions and shape meet the design requirements, that there are no cracks, deformations or other defects on the surface, and that all fasteners such as bolts and nuts are present to ensure that each component can be installed and used normally. 3.

After the measurement is qualified, the arc-shaped pad 2 is welded to the support crossbar 1 using a full welding method. After the welding is completed, the weld is ground to remove the slag and burrs on the surface of the weld, so that the surface of the weld is flat and smooth. Installation of H-beams and bottom plate 1. Place the H-beam steel plate 3 on the upper surface of the arc-shaped pad 2, adjust the position of the H-beam steel plate 3 so that the lower flange of the H-beam steel plate 3 is in close contact with the upper surface of the arc-shaped pad 2, and the center line of the H-beam steel plate 3 coincides with the center line of the arc-shaped pad 2. Then, temporarily fix the H-beam steel plate 3 to the arc-shaped pad 2 by spot welding. 2. Use a level to measure the levelness of the H-beam steel plate 3 to ensure that the H-beam steel plate 3 is in a horizontal state. If there is any tilt, it needs to be adjusted in time. 3. After the measurement is qualified, the H-shaped steel plate 3 is welded to the arc-shaped backing plate 2 using double-sided welding.

Use a right-angle ruler to measure the verticality of the sliding groove 5 to ensure that the sliding groove 5 is perpendicular to the bottom plate 4. If there is any deviation, it needs to be adjusted in time. 3. After the measurement is qualified, the sliding groove 5 is welded to the bottom plate 4 by welding. After the welding is completed, the weld is inspected and ground. 4.

Regularly inspect and tighten bolt 10, generally every 6-12 months. If bolt 10 is found to be loose, tighten it with a wrench in time. The tightening torque shall be determined according to the requirements at the time of installation. 3. If any damage or detachment is found in the insulation tile 8 or the soft insulation layer 13, the insulation tile 8 and the soft insulation layer 13 should be replaced in a timely manner. When replacing, the relevant steps in the installation method should be followed to ensure that the insulation performance after replacement meets the requirements. 4. If cracks or detachment of the weld are found in the welded area, repair welding should be carried out in time. The same welding method and welding materials as the original weld should be used for repair welding. After the repair welding is completed, the repair weld should be inspected and ground. 5. Clean the surface of the guide tube support regularly to remove dust, dirt and other impurities. Use tools such as cloths and brushes for cleaning. Avoid using strong corrosive cleaning agents to prevent corrosion of the surface of the guide tube support.
