Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline support equipment, specifically relating to an energy-saving and heat-insulating pipeline support suitable for high-temperature working conditions. Background Technology

[0002] Pipe supports, as key connecting components between pipelines and supporting structures, play a vital role in pipeline systems in industries such as petrochemicals, power generation, heating, and metallurgy. However, the traditional pipe supports currently in widespread use still have several shortcomings in practical applications: their thermal insulation performance is generally poor, resulting in significant heat loss during pipeline transportation and low energy utilization efficiency; they are insufficiently adaptable to thermal expansion and contraction caused by temperature changes, easily leading to localized stress concentrations in the pipe body or supporting structure; and the fastening methods between pipe supports and pipelines have design flaws, potentially restricting normal pipeline displacement due to excessive tightness or causing unexpected slippage between the pipe and support due to loose connections.

[0003] Although some improved pipe support designs have emerged in existing technologies, most suffer from problems such as complex structures, difficult installation and maintenance, and unsatisfactory actual insulation effects. Especially in high-temperature pipeline applications, how to ensure structural strength while simultaneously considering insulation performance and thermal displacement adaptability remains a technical challenge that needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of energy-saving and heat-insulating pipe support with reasonable structure, excellent heat insulation performance and effective adaptability to pipeline thermal displacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel energy-saving and heat-insulating pipe support includes an upper arc-shaped clamp, a lower arc-shaped clamp, a clamp stabilizing frame, a sliding plate assembly, and a base. The upper and lower arc-shaped clamps are combined by a connecting mechanism to form a cavity for accommodating the pipe. The inner wall of this cavity is provided with a soft heat insulation layer, a hard heat insulation layer, and a friction-enhancing heat insulation coating from the inside to the outside.

[0006] The soft insulation layer uses nano-aerogel material, which is directly wrapped around the outer surface of the pipe to reduce heat transfer by utilizing its excellent thermal insulation performance; the hard insulation layer uses microporous calcium silicate material, which provides both structural support and enhances the thermal insulation effect; the friction-enhancing thermal insulation coating is formed on the surface of the hard insulation layer through a thermal spraying process. This friction-enhancing thermal insulation coating is a ceramic coating doped with silicon carbide particles, which can increase the surface friction coefficient to prevent pipe slippage and provide additional thermal insulation protection.

[0007] The clamping plate stabilizing frame is designed with a U-shaped structure, featuring an open end and a closed end. The open end of the clamping plate stabilizing frame is welded to the outer surfaces of the upper and lower arc-shaped clamping plates, combining the two arc-shaped clamping plates into a single structure, thus improving the load-bearing capacity and deformation resistance of the pipe support. The closed end of the clamping plate stabilizing frame is connected to the sliding plate assembly, forming a complete force transmission path. The closed end of the clamping plate stabilizing frame and the sliding plate are fixedly connected by an interlocking connection structure, which can be a tongue-and-groove or toothed interlocking structure, enabling positioning, force transmission, and detachable assembly between the closed end of the clamping plate stabilizing frame and the sliding plate.

[0008] The sliding plate assembly includes a sliding plate and limiting blocks. The sliding plate is made of 304 stainless steel, and the surface of the sliding plate that contacts the closed end of the clamping plate stabilizer is mirror-polished to reduce sliding friction resistance. The sliding plate is connected to the bottom of the clamping plate stabilizer via an interlocking structure, and the bottom of the sliding plate is connected to the base base via two support bases. A limiting block is provided at each of the two lateral ends of the sliding plate assembly to limit the displacement range of the pipe support.

[0009] The connecting mechanism consists of high-strength bolts, nuts, and disc springs. The disc springs are installed between the nuts and the arc-shaped clamping plate, providing continuous clamping force when the temperature changes, automatically compensating for dimensional changes caused by thermal expansion and contraction, and preventing the connection from loosening.

[0010] Furthermore, the thickness of the soft insulation layer is designed to be 25-40mm, the thickness of the hard insulation layer is 30-50mm, and the thickness of the friction-enhancing insulation coating is 0.5-2mm. This thickness configuration ensures the insulation effect while also taking into account the structural compactness.

[0011] Furthermore, a 10-20mm movable gap is provided between the limiting block and the side wall of the sliding plate. This gap is designed to provide room for normal thermal displacement of the pipeline caused by temperature changes, while preventing the displacement from exceeding the limit.

[0012] Furthermore, the support base is symmetrically arranged at the bottom of the sliding plate, with its upper end welded and fixed to the sliding plate, and its lower end connected to the foundation base by high-strength bolts. This connection method not only ensures structural stability but also facilitates installation and maintenance.

[0013] Furthermore, a high-temperature resistant sealing strip is provided at the joint of the upper and lower arc-shaped clamps. The sealing strip is made of fluororubber or silicone rubber, which can effectively prevent moisture and dust from entering the heat insulation layer, and at the same time play a role in vibration reduction and noise reduction.

[0014] The beneficial effects of this utility model are as follows: By combining a soft insulation layer, a hard insulation layer, and a friction-enhancing insulation coating, a gradient insulation system is constructed, which significantly improves the overall insulation performance of the pipe support and effectively reduces heat loss during pipeline transportation. The integrated disc spring connection mechanism gives the pipe support the ability to adapt to the thermal expansion and contraction of the pipe, and can maintain a suitable clamping force continuously, avoiding the loosening or overtightening problems caused by temperature changes in traditional bolt connections, thus improving operational reliability. The coordinated design of the sliding plate assembly and the limit stop provides a smooth release path for pipeline thermal displacement, and the set movable gap enables bidirectional control of the displacement range, ensuring the long-term safe and stable operation of the pipeline system.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, the novel energy-saving and heat-insulating pipe support of this utility model includes an upper arc-shaped clamping plate 1, a lower arc-shaped clamping plate 2, a clamping plate stabilizing frame 7, a sliding plate assembly, and a base 10.

[0018] The upper arc-shaped clamp 1 and the lower arc-shaped clamp 2 are made of high-strength steel. The upper and lower arc-shaped clamps close together to form a cavity to accommodate the pipe 3. The inner wall of this cavity is sequentially lined with a soft insulation layer 4, a hard insulation layer 5, and a friction-enhancing insulation coating 6 from the inside out. The soft insulation layer 4 is made of nano-aerogel material and directly wraps around the outer surface of the pipe 3, exhibiting good flexibility and extremely low thermal conductivity. The hard insulation layer 5 uses high-strength insulation material, providing both good insulation and the ability to withstand the load of the pipe. The friction-enhancing insulation coating 6 is a ceramic coating doped with silicon carbide particles, formulated from silicon carbide and other materials, and formed through a thermal spraying process. It enhances friction to prevent pipe slippage and provides an additional thermal barrier.

[0019] The upper arc-shaped clamping plate 1 and the lower arc-shaped clamping plate 2 are closed by a connecting mechanism, which includes a high-strength bolt 11, a nut 12, and a disc spring 13. The disc spring 13 is fitted onto the bolt 11 and provides continuous clamping force during temperature changes, preventing loosening of the connection due to thermal expansion and contraction. A high-temperature resistant sealing strip 15 is provided at the joint between the upper arc-shaped clamping plate 1 and the lower arc-shaped clamping plate 2. The sealing strip is made of fluororubber or silicone rubber; this effectively prevents external moisture and dust from entering, while also reducing vibration and noise transmission.

[0020] The clamping plate stabilizer 7 has a U-shaped structure with an open end and a closed end. The open end of the clamping plate stabilizer 7 is fixedly connected to the outer surfaces of the upper arc-shaped clamping plate 1 and the lower arc-shaped clamping plate 2 by welding, connecting the upper and lower arc-shaped clamping plates into a whole, evenly transferring the pipe load, and enhancing the bending resistance. The closed end of the clamping plate stabilizer 7 is connected to the sliding plate assembly through an interlocking connection structure.

[0021] The sliding plate assembly includes a sliding plate 8 and limit stops 9. The sliding plate 8 is made of 304 stainless steel, and the surfaces of the sliding plate 8 and the closed end of the clamping plate stabilizer are mirror-polished. The sliding plate 8 is fixedly connected to the clamping plate stabilizer 7, and the bottom of the sliding plate is connected to the base base 10 via two support bases 14 to ensure smooth sliding during pipeline thermal displacement. Limit stops 9 are provided at both ends of the sliding plate assembly, maintaining a 15mm gap with the upper sliding plate 8, which allows normal thermal displacement while preventing excessive displacement.

[0022] The support base 14 is symmetrically arranged at the bottom of the sliding plate 8 and is connected to the bottom of the sliding plate 8 by welding. It is also connected to the base base 10 by high-strength bolts, which facilitates installation and maintenance.

[0023] During installation, the lower arc-shaped clamp 2 is first placed below the pipe, and then the upper arc-shaped clamp 1 is installed and secured using a connecting mechanism. Next, the clamp stabilizing bracket 7 and the sliding plate assembly are installed, and finally, the entire pipe support is fixed to the supporting structure via the base 10.

[0024] When the pipe expands due to heat, the thermal stress is released by the relative sliding of the sliding plate assembly. At the same time, the three-layer insulation structure effectively reduces heat loss, and the disc spring maintains a constant clamping force to ensure the safe and stable operation of the system.
