[0001] The utility model belongs to the technical field of direct-buried steam insulation pipe installation, in particular to a high-temperature steam pipeline insulation guide bracket. Background Art

[0002] When installing the steam direct buried pipeline, sliding brackets, guide brackets and fixed brackets are installed in sequence on both sides of the pipeline expansion area towards the far end. The guide bracket is located between the sliding bracket and the fixed bracket. In the middle section away from the pipeline expansion area, the pipeline is supported and limited along the axial direction.

[0003] In the existing guide bracket, the clamping part or supporting part of the bracket is in sliding contact with the pipeline. After the pipeline expands, it compresses the clamping or supporting working surface, and the friction coefficient increases. When deforming along the axial direction, it causes greater wear on the pipeline and the bracket, and greater axial resistance, which affects the overall stability of the bracket.

[0006] Furthermore, the guide clamp slides along the slide rail on the base through the sliding seat at the bottom, the guide clamp is installed on the sliding seat through bolts, the fixed clamp is installed on the support plate through the fixed seat, and the fixed clamp is installed on the fixed seat through bolts.

[0007] Furthermore, the limit support assembly includes a limit rod and a support spring wound around the limit rod, one end of the limit rod is fixed to the side of the sliding seat, and the other end movably passes through the fixed seat, and the support spring is located between the fixed seat and the sliding seat.

[0009] Furthermore, a fixed support plate is fixedly installed at one end of the support plate near the pipe deformation position, and the upper end of the fixed support plate is arc-shaped and concave to form a supporting groove for supporting the pipe, and the slide rail is located between the fixed support plate and the fixed base.

[0010] After adopting the above structure, the beneficial effects of the utility model are as follows: the utility model proposes a high-temperature steam pipe insulation guide bracket, which slides along the slide rail in a direction as the pipe is deformed through the set guide clamp when the pipe is axially deformed, thereby avoiding friction damage between the deformed pipe and the clamping member, and utilizing the fixed seat and the fixed support plate to limit the deformation sliding stroke while utilizing the limit support assembly to perform a certain buffering unloading force, and further utilizing the annular through hole formed by the fixed clamp to clamp and position away from the pipe expansion area, and utilizing the fixed support plate to guide near the supporting area, so as to cope with the compressive force and axial displacement generated by the pipe expansion, and reduce the friction damage between the pipe and the bracket, that is, while protecting the pipe, limiting the axial deformation of the pipe, maintaining the overall stability of the bracket, and ensuring the normal operation of the pipe.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0018] like Figure 1-3 As shown, a high-temperature steam pipe insulation guide bracket includes a base 1, a guide clamp 2, a fixing clamp 3 and a limit support assembly; the base 1 has a corresponding supporting force, and a support plate 4 is arranged at the top, and the support plate 4 is connected to the base 1 by a damping rotation through a turntable 5; here, preferably, the base 1 can be an I-shaped, and the pipeline is supported overhead, and the turntable 5 is connected to the top of the base 1 by a damping rotation, and a certain damping value is set. In the expansion area of ​​the pipeline, the upper end component of the base 1 can be radially displaced with the pipeline, thereby reducing the resistance of the bracket to the pipeline when the pipeline is deformed, and ensuring the stability of the support of the base 1.

[0019] In this embodiment, the clamping working surfaces formed by the guide clamp 2 and the fixed clamp 3 are both equipped with an insulation ring 11. The insulation ring 11 is made of polystyrene resin as raw material and has a certain compressive resistance and a low thermal conductivity coefficient.

[0020] In some preferred embodiments, the guide clamp 2 is slidably installed on the support plate 4 along the central axis direction of the pipeline, and is a multi-type structure, which can perform corresponding splicing and splitting operations, and an annular through hole is provided at a predetermined position of the working surface; the fixed clamp 3 is located at one end of the support plate 4 away from the deformation position of the pipeline, and is a multi-type structure, which can perform corresponding splicing and splitting operations, and an annular through hole is provided at a predetermined position of the working surface; wherein, the guide clamp 2 slides along the slide rail 7 on the base 1 through the sliding seat 6 at the bottom, the guide clamp 2 is installed on the sliding seat 6 by bolts, and the fixed clamp 3 is installed on the support plate 4 through the fixing seat 8, The fixing clamp 3 is installed on the fixing seat 8 by bolts; specifically, the splicing piece of the guide clamp 2 and the fixing clamp 3 forms a through hole at the top along the splicing direction for the screw to pass through, and nuts are provided at both ends of the screw to fix the screw, and the splicing distance of the splicing pieces is adjusted to form annular through holes of different sizes. In addition, fixing ears are provided at the lower part of the splicing part of the splicing piece, and the guide clamp 2 and the fixing clamp 3 are respectively fixed to the installation working surfaces of the sliding seat 6 and the fixing seat 8 by bolts. Correspondingly, strip holes are formed on the installation working surfaces of the sliding seat 6 and the fixing seat 8, which can facilitate the splicing pieces of the clamps to clamp the pipeline at different distances.

[0021] It should be noted that the support plate 4 is fixedly mounted with a fixed support plate 12 at one end near the deformation position of the pipeline, and the upper end of the fixed support plate 12 is arc-shaped and concave to form a supporting groove 13 for supporting the pipeline, and the slide rail 7 is located between the fixed support plate 12 and the fixed base. Here, preferably, the supporting groove 13 supports the working surface to be equipped with a heat insulation ring 11 of the same material as the working surface clamped by the guide clamp 2 and the fixed clamp 3.

[0022] In some preferred embodiments, based on the above embodiments, the limit support assembly is located between the guide clamp 2 and the fixed clamp 3, and deforms accordingly as the guide clamp 2 moves. Specifically, the limit support assembly includes a limit rod 9 and a support spring 10 wound around the limit rod 9, one end of the limit rod 9 is fixed to the side of the sliding seat 6, and the other end movably passes through the fixed seat 8, and the support spring 10 is located between the fixed seat 8 and the sliding seat 6.

[0023] During specific use, the guide bracket of the present application is installed between the fixed bracket and the sliding bracket of the high-temperature steam pipe. In the expansion area of ​​the pipe, multiple axial positioning of the pipe is performed. The pipe passes through the annular through hole formed by the fixed clamp 3, the annular through hole formed by the guide clamp 2, and the supporting groove 13 above the fixed support plate 12 along the axial direction from the far end to the proximal end of the expansion area.

[0024] After the pipeline expands due to heat, the guide support part of the guide bracket limits the axial displacement of the pipeline. The axial thrust of the pipeline causes the sliding seat 6 to carry the guide clamp 2 to slide stably along the slide rail 7, and at the same time, squeeze the support spring 10, which applies a directional force to the sliding seat 6 to unload and dampen the axial displacement of the pipeline. The guide clamp 2 and the pipeline move with the sliding seat 6, reducing the loss caused by the relative displacement of the pipeline and the guide clamp 2. The fixed seat 8 and the fixed support plate 12 limit the axial displacement stroke of the guide clamp 2, limit the axial displacement direction within a certain stroke unit, buffer the thrust formed by the axial displacement, effectively protect the clamp and the pipeline, and ensure the stability of the base 1.

[0025] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the scope of protection of the utility model.
