Description

Technical Field

[0001] The utility model belongs to the field of pipeline support and hanger, and in particular relates to an elastic support and horizontal limit combined support and hanger and a pipeline system. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The support and hanger is an indispensable part of the pipeline system. It supports and limits the displacement of the pipeline to ensure the stability, safety and reliability of the pipeline during installation, use and maintenance. By setting the support and hanger reasonably, the pipeline vibration can be prevented and the stability of the pipeline can be increased.

[0004] In tower-type solar thermal power station projects, the molten salt pipelines in the tower have the characteristics of high drop, small layout space, and high temperature, which have high requirements for the setting of supports and hangers. The characteristics of high drop lead to a long pipe system, which requires a large number of supports and hangers, and high costs; the space inside the tower is relatively small, and the layout space of the pipelines inside the tower is limited. Therefore, the pipelines in the tower are generally arranged in parallel with multiple pipelines, and the distance between adjacent pipelines is relatively small. The roots of conventional horizontal limit and damping supports and hangers cannot be installed; the design temperature of the pipeline is as high as 575℃, and a large number of spring supports and hangers need to be set. At the same time, in order to ensure safe operation, each support and hanger needs to be insulated, which leads to a particularly high installation cost of a single support and hanger, so it is necessary to minimize the number of supports and hangers to reduce investment costs.

[0005] The horizontal space of the molten salt pipeline in the tower is relatively small. At the same time, each horizontal pipeline has vertical displacement. In the "Design Manual of Steam-Water Pipeline Supports and Hangers for Thermal Power Plants" (2010), conventional limit supports and hangers cannot meet the requirements: for example, the guide support cannot meet the vertical displacement requirements; when setting a single radial limit, the height of its root structure needs to be above the center height of the horizontal pipe, which cannot be achieved due to the influence of horizontal space; the tension rod also requires horizontal space. When the horizontal space is limited, the root structure cannot be installed. Utility Model Content

[0006] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a combined support and hanger bracket and pipeline system of elastic support and horizontal limit, in which the guide support is combined with the elastic bracket to transfer the root of the limit support hanger (i.e. the horizontal limit force point) from the center line of the pipeline to the bottom of the pipeline, and it is no longer affected by the horizontal space.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The first aspect of the utility model provides an elastic support and horizontal limit combined support and hanger bracket.

[0012] The sliding blocks are arranged on two opposite sides of the inner surface of the vertical support portion;

[0013] The sliding block is fixedly connected to the support frame;

[0014] The top of the clamp-type guide support is used to fix and support the target pipeline, and the bottom extends into the interior of the vertical support portion and contacts the bracket-type spring assembly; the two sides of the clamp-type guide support contact the sliding block.

[0015] As an implementation manner, the support frame is an axisymmetric structure.

[0016] As an implementation mode, the vertical support portion is a standard H-shaped steel; the leg portion includes two legs evenly connected to the outside of the standard H-shaped steel.

[0017] As an implementation manner, the clamping guide support is an axisymmetric structure.

[0018] As an embodiment, the bracket-type spring assembly includes an elastic element and a support column; the clamp-type guide support includes a clamping portion and a sliding portion; one end of the support column is connected to the elastic element, and the other end is in contact with the sliding portion; the upper end of the sliding portion is connected to the clamping portion, and both sides of the sliding portion are in contact with the sliding block.

[0019] As an implementation manner, the clamping portion includes a first arc-shaped hoop and a second arc-shaped hoop; the first arc-shaped hoop and the second arc-shaped hoop are wrapped around the outside of the target pipe.

[0020] As an implementation manner, both ends of the first arc-shaped hoop and the second arc-shaped hoop are fixedly connected by bolts.

[0021] As an implementation manner, the elastic element is a spring.

[0022] As an implementation mode, the sliding block is a standard steel section with a sliding plate.

[0023] A second aspect of the utility model provides a pipeline system.

[0024] A pipeline system comprises a pipeline and the elastic support and horizontal limit combined support and hanger as described above; the elastic support and horizontal limit combined support and hanger is used to support the pipeline.

[0025] The beneficial effects of the utility model are:

[0026] The utility model provides an elastic support and horizontal limit combined support and hanger and pipeline system, which combines a support spring component with a clamping guide support, utilizes the clamping guide support to clamp the target pipeline, and with the gravity of the target pipeline, causes the sliding block to move up and down along the slide groove, and finally utilizes the support spring component to support the clamping guide support, so that the root of the limit support and hanger (i.e., the horizontal limit force point) is transferred from the center line of the pipeline to the bottom of the pipeline, and is no longer affected by the horizontal space, and can have a buffering effect on the pipeline as it descends due to gravity, thereby improving the working stability of the support and hanger.
