Description

Technical Field

[0001] This utility model relates to the field of pipe support technology, specifically to an internal sliding guide support for steam pipes. Background Technology

[0002] Steam pipelines are special pressure pipeline systems used in modern industry to transport high-temperature, high-pressure steam. They are widely used in many industries such as thermal power plants, petrochemicals, district heating, textiles, and food processing, and are the core arteries for energy transfer and process production.

[0003] In traditional steam piping systems, sliding guide supports are a very common component. Their core design objectives are to support weight, allow axial sliding, and restrict radial movement. A traditional sliding guide support consists of a support structure fixed to the ground, wall, or steel frame, typically welded from shaped steel (such as channel steel or I-beams) or steel plates. Pipe clamps or supports are installed within the support to directly hold or support the steam pipe. It usually consists of two semi-circular or saddle-shaped components bolted together to clamp the pipe in place. A sliding block is installed on the pipe clamp or support; this sliding block is typically made of a low-friction material, most commonly polytetrafluoroethylene (PTFE), graphite lubricant, or stainless steel.

[0004] Although traditional sliding guide supports can slide relative to the base structure, the sliding mode of traditional structures is static friction of surface contact, which has a large sliding friction force. Especially under harsh working conditions such as high temperature, humidity or dust, the sliding contact surface is prone to rust, oil stains or dust accumulation, which leads to a sharp increase in the coefficient of friction, and may even turn the sliding friction into a "jammed" state, making it difficult to ensure that the steam pipeline can slide smoothly and with low resistance. Utility Model Content

[0005] The purpose of this utility model is to provide an internal sliding guide support for steam pipelines, addressing the defects and shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an internal sliding guide bracket for steam pipes, comprising a connecting frame, a connecting hole formed on the connecting frame for the steam pipe to pass through, and two connecting seats symmetrically arranged on the connecting frame within the connecting hole, and rotating rollers rotatably arranged on the two connecting seats for the steam pipe to move radially within the connecting hole. The rotating rollers are provided with an arcuate portion for fitting against the arcuate surface of the outer surface of the steam pipe, the arcuate portion being drum-shaped on the rotating rollers. The connecting seats include two connecting frames symmetrically arranged on the left and right sides, and fixed shafts are provided at the left and right ends of the rotating rollers. The rotating rollers are rotatably arranged between the two connecting frames via the fixed shafts.

[0007] Further benefits: When the two rotating rollers with arc settings are located at the upper and lower ends of the steam pipe, they can fit against the surface of the steam pipe through the arc portion of the rotating rollers. Compared with directly setting cylindrical rotating rollers, only two rollers are needed to provide a limiting effect on the left and right directions of the steam pipe while the rotating rollers are rotating.

[0008] A further improvement is that the surface of the rotating roller is provided with a heat insulation layer.

[0009] Further benefits: The insulation layer prevents damage to the rotating rollers from high-temperature steam pipes, thus extending the service life of the rotating rollers.

[0010] A further improvement is that the heat insulation layer is a silicone rubber layer or a polyetheretherketone layer.

[0011] A further improvement is that: the upper end face of each of the connecting brackets is provided with a connecting hole for the fixed shaft to be vertically placed on the connecting bracket, the fixed shaft can rotate in the connecting hole, and each of the connecting brackets is provided with a limiting member located in the connecting hole and above the fixed shaft to prevent the fixed shaft from disengaging from the connecting hole after it is placed in the connecting hole.

[0012] A further improvement is that the limiting component includes an anti-detachment plate slidably disposed on the connecting frame, located within the connecting opening and above the fixed shaft; a guide side groove formed on the connecting frame and communicating with the connecting opening; and a guide side plate disposed on the side end face of the anti-detachment plate and in clearance fit with the guide side groove, which guides the sliding direction of the anti-detachment plate and restricts the vertical movement of the anti-detachment plate.

[0013] Further effect: When the fixed shaft is vertically inserted into the connecting openings of the left and right connecting brackets, the anti-detachment plate is pushed in by aligning it with the guide side groove through the guide side plate, so that the anti-detachment plate slides into the connecting opening above the fixed shaft. The guide side plate guides the sliding direction of the anti-detachment plate and restricts the vertical movement of the anti-detachment plate, thereby restricting the vertical movement of the fixed shaft in the connecting opening, so as to achieve the effect of restricting the fixed shaft.

[0014] A further improvement is that the connecting frame has a threaded through hole, which is connected to the connecting opening. The threaded through hole is located opposite the guide side groove. The connecting frame is threadedly connected in the threaded through hole to a push bolt for pressing the side end face of the anti-detachment plate after the anti-detachment plate slides into the connecting opening, thereby increasing the sliding resistance of the anti-detachment plate in the connecting opening.

[0015] Further benefits: After the anti-detachment plate is pushed into the connecting opening to restrict the vertical direction of the fixed shaft, the abutment bolt can be screwed into the threaded hole, so that the threaded part of the abutment bolt is pressed against the side end face of the anti-detachment plate, thereby increasing the sliding resistance of the anti-detachment plate in the connecting opening. This can prevent the anti-detachment plate from being pulled out of the connecting opening during the rotation or lateral movement of the rotating roller, thus improving the fixing effect of the anti-detachment plate in the connecting opening.

[0016] A further improvement is that the connecting hole is a hexagonal or square hole.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are as follows: The connecting frame is fixed to the ceiling or wall by means of hoisting or bolting. Multiple connecting frames can be set and several are equidistantly set along the length of the steam pipe to provide support for the steam pipe. Then, the steam pipe is inserted through the connecting hole, so that the steam pipe is located between the upper and lower rotating rollers. The arc part on the rotating roller is in contact with the outer surface of the steam pipe to increase the contact area between the rotating roller and the steam pipe and reduce the occurrence of slippage. Through the rotation of the upper and lower rotating rollers on the connecting frame, the steam pipe can move axially in the connecting hole. Compared with the traditional static friction of surface contact, the sliding friction is smaller and it is not easy to cause jamming that affects the sliding of the steam pipe in the connecting hole. This can further ensure that the steam pipe can slide smoothly and with low resistance axially. Attached Figure Description

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] See Figures 1 to 4 As shown, the technical solution adopted in this specific embodiment is: an internal sliding guide bracket for steam pipes, including a connecting frame 1, a connecting hole 2 opened on the connecting frame 1 for the steam pipe to pass through, and two connecting seats 3 symmetrically arranged on the connecting frame 1 within the connecting hole 2, and rotating rollers 4 rotatably arranged on the two connecting seats 3 for the steam pipe to move radially in the connecting hole 2. The rotating rollers 4 are provided with arc-shaped portions 5 for fitting with the arc surface of the outer surface of the steam pipe. The arc-shaped portions 5 are waist-shaped on the rotating rollers 4. The connecting seats 3 include two connecting frames 6 symmetrically arranged on the left and right. The left and right ends of the rotating rollers 4 are provided with fixed shafts 8. The rotating rollers 4 are rotatably arranged between the two connecting frames 6 through the fixed shafts 8.

[0023] The specific curvature of the arc portion 5 is preset according to the curvature of the steam pipe when placed on the rotating roller 4, ensuring that the rotating roller 4 fits the surface of the steam pipe when it is placed on the roller. The connecting frame 1 is suspended from the ceiling or fixed to the wall by bolts at its side. The connecting frame 1 can be circular or polygonal in shape.

[0024] The surface of the rotating roller 4 is provided with a heat insulation layer (not shown in the figure).

[0025] The heat insulation layer (not shown in the figure) is a silicone rubber layer or a polyetheretherketone layer.

[0026] The preferred material is silicone rubber, an insulating material with excellent high-temperature performance, maintaining good insulation properties even at extremely high temperatures. Furthermore, it possesses high tensile strength and abrasion resistance, extending its service life through these properties. Polyetheretherketone (PEEK): This is a high-temperature, high-performance polymer that not only has good insulation properties but also excellent chemical stability, enabling stable operation in high-temperature environments. The heat insulation layer (not shown in the figure) is achieved by laminating, bonding, or directly setting the material of the rotating roller 4 to silicone rubber or PEEK.

[0027] Each of the connecting brackets 6 has a connecting hole 7 on its upper end surface for vertically inserting the fixed shaft 8 into the connecting bracket 6. The fixed shaft 8 can rotate in the connecting hole 7. Each of the connecting brackets 6 has a limiting member located in the connecting hole 7 and above the fixed shaft 8 to prevent the fixed shaft 8 from disengaging from the connecting hole 7 after it is inserted into the connecting hole 7.

[0028] like Figure 4 As shown, the connecting opening 7 is opened downwards from the upper end of the connecting bracket 6. The opening width of the connecting opening 7 is 0.1m-2mm larger than the diameter of the fixed shaft 8, so that the fixed shaft 8 can rotate in the connecting opening 7 without easily moving in the front-to-back direction. The lower end of the connecting opening 7 can be square or an arc surface with the same curvature as the surface of the fixed shaft 8.

[0029] The limiting components include an anti-detachment plate 9 slidably disposed on the connecting frame 6, located within the connecting opening 7 and above the fixed shaft 8; a guide side groove 10 formed on the connecting frame 6 and communicating with the connecting opening 7; and a guide side plate 13 disposed on the side end face of the anti-detachment plate 9 and in clearance fit with the guide side groove 10, which guides the sliding direction of the anti-detachment plate 9 and restricts the vertical movement of the anti-detachment plate 9.

[0030] The guide side groove 10 is provided through the length of the connecting opening 7. When the anti-detachment plate 9 slides into the connecting opening 7, there is a gap of 0.1mm-2mm between the lower end of the anti-detachment plate 9 and the upper end of the fixed shaft 8.

[0031] The connecting frame 6 has a threaded through hole 11, which is connected to the connecting opening 7. The threaded through hole 11 is located opposite the guide side groove 10. The connecting frame 6 is threaded in the threaded through hole 11 and has a push bolt 12 for pressing the side end face of the anti-detachment plate 9 after the anti-detachment plate 9 slides into the connecting opening 7 to increase the sliding resistance of the anti-detachment plate 9 in the connecting opening 7.

[0032] The location of the threaded opening is as follows: Figure 3 and Figure 4 As shown. Without the threaded through hole 11 and the abutment bolt 12, two guide side grooves 10 and guide side plates 13 can be provided, symmetrically arranged. To improve the fixing effect of the abutment bolt 12, a connecting slot can be opened on the side end face of the anti-detachment plate 9 for the threaded portion of the abutment bolt 12 to pass through.

[0033] The connecting hole 2 is a hexagonal or square hole. By using a hexagonal or square hole, when the connecting seat 3 is set in the connecting hole 2, the installation distance between the connecting seat 3 and the rotating roller 4 and the connecting frame 1 can be increased, thereby improving the space utilization of the connecting seat 3 compared to setting a circular hole.

[0034] The working principle of this utility model is as follows: The connecting frame 1 is fixed to the ceiling or wall by means of hoisting or bolting. Multiple connecting frames 1 can be set and several are equidistantly set along the length of the steam pipe to provide support for the steam pipe. Then, the steam pipe is inserted through the connecting hole 2, so that the steam pipe is located between the two upper and lower rotating rollers 4. The arc part 5 on the rotating roller 4 fits against the outer surface of the steam pipe to increase the contact area between the rotating roller 4 and the steam pipe and reduce the occurrence of slippage. By rotating the two upper and lower rotating rollers 4 on the connecting frame 6, the steam pipe can move axially in the connecting hole 2. Compared with the traditional static friction of surface contact, the sliding friction is smaller and it is not easy to cause jamming that affects the sliding of the steam pipe in the connecting hole 2. This can further ensure that the steam pipe can slide smoothly and with low resistance axially. When the fixed shaft 8 is vertically inserted into the connecting opening 7 of the left and right connecting brackets 6, the anti-detachment plate 9 is pushed in by aligning the guide side plate 13 with the position of the guide side groove 10, so that the anti-detachment plate 9 slides into the connecting opening 7 above the fixed shaft 8. The guide side plate 13 guides the sliding direction of the anti-detachment plate 9 and restricts the vertical movement of the anti-detachment plate 9, thereby restricting the vertical movement of the fixed shaft 8 in the connecting opening 7, so that the fixed shaft 8 can only be in a rotatable state in the connecting opening 7. After the anti-detachment plate 9 is pushed into the connecting opening 7 to restrict the vertical direction of the fixed shaft 8, the abutment bolt 12 can be screwed into the threaded through hole 11, so that the threaded part of the abutment bolt 12 is pressed against the side end face of the anti-detachment plate 9, thereby increasing the sliding resistance of the anti-detachment plate 9 in the connecting opening 7. This can prevent the anti-detachment plate 9 from detaching from the connecting opening 7 during the rotation or lateral movement of the rotating roller 4, and improve the fixing effect of the anti-detachment plate 9 in the connecting opening 7.
