Description

Technical Field

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

[0002] When installing direct buried steam pipelines, it is necessary to separate one end or install compensators at the connection between two pipelines. The square compensators are made of pipes, and smaller ones can be made with one pipe. In particular, since the top of the compensator is subjected to the greatest force when it is working, the top should be made with one pipe, and welds are not allowed.

[0003] In the prior art, during installation, fixed brackets, guide brackets and movable brackets are required to support both sides of the directional compensator connected to the direct-buried steam pipe; the two ends of the square compensator are clamped between the movable brackets, and there is generally sliding friction between the clamping parts and the base of the bracket. When the directional compensator expands due to heat, the expansion of the pipeline compresses the clamping parts (increasing the static friction between the supporting working surface and the bracket base), and a lateral (pipeline radial) thrust is generated. When the clamping parts move laterally under the action of the above thrust, the resistance becomes greater, affecting the stability of the bracket and the normal operation of the steam pipe. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a movable bracket for a directly buried steam pipeline to solve the above problem.

[0005] The technical solution adopted by the utility model is as follows: a movable support for a directly buried steam pipe, comprising a support seat, a sliding clamping assembly and an extrusion deformation assembly; the support seat has a corresponding supporting force; a support platform is formed at the upper end, and the support platform has a corresponding supporting force; the sliding clamping assembly comprises a moving block, which is driven by the pipe deformation force and performs a corresponding displacement on the support platform; a clamping piece is fixed on the moving block and performs a corresponding supporting and clamping operation; the extrusion deformation assembly is arranged at the edge of the support platform, enclosing the periphery of the sliding block, and performs a corresponding deformation when collided by the moving block.

[0006] Furthermore, the extrusion deformation component includes an enclosure, an extrusion sliding sheet and an arc-shaped member; the enclosure forms a closed space with an upper end opening along the edge of the supporting platform; the extrusion sliding sheet is respectively located at the four corners of the enclosure, has a predetermined bending curvature and a predetermined elastic deformation force, one end is fixed to the corresponding side wall of the enclosure in the direction of the central axis of the pipeline, and the other end is connected to the sliding component, and is attached to the corresponding inner walls of the enclosure on both sides of the central axis of the pipeline through the sliding component to perform corresponding sliding operations; the arc-shaped member has a predetermined bending curvature and a predetermined elastic deformation force, is assembled on the corresponding side wall of the enclosure in the direction of the central axis, and is fixed between the fixed ends of the extrusion sliding sheet.

[0007] Furthermore, the sliding assembly includes fixed blocks, which are respectively fixed to the inner walls of the enclosure on both sides of the central axis of the pipeline; a limiting rod, which passes through the fixed block and has both ends extending along the central axis of the pipeline and fixed to the corresponding inner walls of the enclosure; a sliding block, which is fixedly connected to the sliding end of the extrusion sliding sheet and slides along the limiting rod; a support spring, which is wound on the limiting rod and is located between the sliding block and the corresponding inner wall of the enclosure.

[0008] Furthermore, a groove is provided on the support platform, a support roller is installed in the groove, a central axis direction of the support roller is parallel to a central axis direction of the pipeline, and the moving block is located on the support roller.

[0009] Furthermore, cover plates are arranged on both sides of the enclosure along the central axis direction of the pipeline, a limiting channel is formed between the two cover plates, and the clamping member extends out of the limiting channel.

[0010] Furthermore, a mounting groove is provided on the sliding working surface of the sliding block, a universal ball is installed in the mounting groove, and the universal ball rolls against the corresponding inner wall of the enclosure.

[0011] After adopting the above structure, the beneficial effects of the utility model are as follows: a movable support for a directly buried steam pipe proposed by the utility model can, through the set extrusion deformation component, play an energy absorption and buffering effect in all directions when the pipe deformation causes the clamping part and the moving block to be displaced, thereby avoiding sudden and large shaking. In addition, through the set support roller, the downward pressure caused by the expansion of the pipe is reduced when the moving block is radially displaced, the sliding friction is reduced, and the energy absorption and buffering after the collision of the extrusion sliding sheet at the edge and the arc-shaped part are cooperated, thereby reducing the movement amplitude, reducing shaking, reducing the influence of radial movement on the support seat and the wear between the moving block and the support platform, thereby ensuring the normal operation of the steam pipe.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. 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. Example 1

[0020] like Figure 1-4 As shown, a movable support for a directly buried steam pipe includes a support seat 1, a sliding clamping assembly and an extrusion deformation assembly; the support seat 1 has a corresponding supporting force; a support platform 2 is formed at the upper end, and the support platform 2 has a corresponding supporting force; the sliding clamping assembly includes a moving block 3, which is driven by the pipe deformation force and performs a corresponding displacement on the support platform 2; a clamping member 4 is fixed on the moving block 3 and performs a corresponding supporting and clamping operation; the extrusion deformation assembly is arranged at the edge of the support platform 2, and is surrounded by the sliding block 10, and is deformed accordingly when collided by the moving block 3.

[0021] As a preferred embodiment of the present application, a groove is opened on the support platform 2, and a support roller 12 is installed in the groove. The central axis direction of the support roller 12 is parallel to the central axis direction of the pipeline. The moving block 3 is located on the support roller 12, which reduces the contact area with the support platform 2 and reduces friction during radial movement, thereby reducing the friction resistance between the moving block 3 and the support platform 2. Example 2

[0022] On the basis of Example 1, specifically, the extrusion deformation component includes an enclosure 5, an extrusion sliding sheet 6 and an arc-shaped member 7; the enclosure 5 forms a closed space with an upper end opening along the edge of the support platform 2; the extrusion sliding sheet 6 is respectively located at the four corners of the enclosure 5, has a predetermined bending curvature and a predetermined elastic deformation force, one end is fixed to the corresponding side wall of the enclosure 5 in the direction of the central axis of the pipeline, and the other end is connected to the sliding component, and is attached to the corresponding inner walls of the enclosure 5 on both sides of the central axis of the pipeline through the sliding component to perform corresponding sliding operations; the arc-shaped member 7 has a predetermined bending curvature and a predetermined elastic deformation force, is assembled on the corresponding side wall of the enclosure 5 in the direction of the central axis, and is fixed between the fixed ends of the extrusion sliding sheet 6. In addition, it should be noted here that cover plates 13 are arranged on both sides of the enclosure 5 along the central axis of the pipeline, and a limiting channel is formed between the two cover plates 13, and the clamping member 4 extends out of the limiting channel.

[0023] Among them, the sliding assembly includes a fixed block 8, which is respectively fixed to the inner wall of the enclosure 5 on both sides of the central axis of the pipeline; a limiting rod 9, which passes through the fixed block 8 and has both ends extending along the central axis direction of the pipeline and fixed on the corresponding inner wall of the enclosure 5; a sliding block 10, which is fixedly connected to the sliding end of the extruded sliding sheet 6 and slides along the limiting rod 9. Specifically, here, it is preferred that an installation groove is provided on the sliding working surface of the sliding block 10, and a universal ball 14 is installed in the installation groove, and the universal ball 14 rolls against the corresponding inner wall of the enclosure 5; a support spring 11 is wound on the limiting rod 9 and is located between the sliding block 10 and the corresponding inner wall of the enclosure 5.

[0024] During specific use, the clamping member 4 is a semi-wrapped clamping member 4. After the steam pipe expands and deforms, the clamping member 4 and the moving block 3 are pressed downward; when the square compensator is deformed, the top end of the square compensator deforms and pulls the two sides to tilt toward its top end, and the moving block 3 is displaced along the central axis of the pipeline, colliding with the arc-shaped members 7 on both sides, absorbing energy and limiting the axial movement; at the same time, when the directional compensator is deformed, the moving block 3 will move along the radial direction of the pipeline, reducing the moving friction during radial movement (avoiding the support seat 1 from deflecting and becoming unstable under the action of a large static friction force), reducing wear and in the path of limiting movement, colliding at the edge to squeeze the sliding sheet 6, squeezing the sliding sheet 6 to deform, and one end of the slide slides along the limit rod 9, squeezing the support spring 11, absorbing energy and reducing shock, reducing the collision force, and ensuring the normal operation of the steam pipeline.

[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.
