AI Technical Summary
Existing spring supports cannot effectively limit the horizontal displacement of pipelines while bearing pipeline loads, leading to skewness or failure of the load column, and failing to meet the requirements of simultaneous load bearing and limiting.
A spring support was designed, comprising a housing, a spring load-bearing component, a bearing guide component, and a limiting component. The bearing guide component bears the horizontal force generated by the thermal displacement of the pipeline, and the limiting component restricts the radial and axial horizontal displacement of the pipeline. The low friction characteristics of the rolling or sliding bearings ensure that the load column does not deviate.
It effectively limits the radial and axial horizontal displacement of the pipeline while bearing the pipeline load, avoids the load column from tilting, and ensures the stability of the support and the effective output load.

[0002] There are many pipelines for conveying high-temperature medium in petrochemical plants. Because of different temperature conditions such as hot state or cold state in the operation process of the pipelines, the pipeline support parts and the structure root parts will have relative thermal displacement in the vertical direction. In this case, spring supports need to be selected to bear the load of the pipelines to prevent the problem of pipeline emptying or overloading. In many application scenarios, the pipeline support not only needs to bear the load of the pipeline in the vertical direction, but also needs to limit the radial and axial horizontal displacement of the pipeline to achieve the following purposes: reducing the stress and moment of the equipment nozzle; reducing the radial and axial horizontal displacement of the pipeline; resisting wind, earthquake and other accidental loads; and improving the stability of the pipeline system.
[0003] The existing spring support can meet the load bearing requirements of pipelines with different loads, but the ability to limit the horizontal displacement of the pipeline is poor.

[0024] The present invention will now be further described with reference to the accompanying drawings.
[0025] The implementation of the technical solution of this utility model patent will be further described below with reference to the accompanying drawings.
[0026] like Figures 1 to 8 As shown, a spring bracket that simultaneously provides load-bearing and horizontal limiting functions includes a housing, a spring load-bearing assembly, a bearing guide assembly, and a limiting assembly. The bearing guide assembly is connected to the top of the housing and symmetrically arranged on both sides of the load column (3) of the spring load-bearing assembly, with the bearing guide assembly in close contact with the load column (3). The limiting assembly is symmetrically arranged on the load plate (2) of the spring load-bearing assembly. The bearing guide assembly can withstand the horizontal force generated by the thermal displacement of the pipeline, ensuring that the load column of the spring bracket does not tilt. The bearing guide assembly and the limiting assembly work together to effectively limit the radial and axial horizontal displacement of the pipeline.
[0027] The spring load-bearing assembly includes a load plate (2), a load column (3), a spring element (4), a guide column (5), and a spring pressure plate (6). One or more sets of spring elements (4) are installed according to the magnitude of the vertical load and horizontal force on the pipeline. Each set of spring elements (4) corresponds to one load column (3). The spring elements (4) are installed inside the shell (1) of the box structure, with their upper and lower ends connected to the spring pressure plate (6) and the bottom plate of the shell, respectively. The spring elements (4) are mounted on the guide column (5), the upper end of which is connected to the spring pressure plate (6). The load column (3) passes through the shell (1), with its upper and lower ends connected to the load plate (2) and the spring pressure plate (6), respectively.
[0028] The bearing guide assembly includes an arc-shaped rotating shaft (7), bearings (8), and bearing housings (9), and is housed within a protective cover (13). Two sets of bearings (8) are housed within the bearing housings (9), fixing both ends of the arc-shaped rotating shaft (7) to the bearings (8). The arc-shaped rotating shaft (7) can rotate around its central axis but cannot move along it. The bearings (8) include rolling bearings and sliding bearings. Utilizing the low coefficient of friction of the bearings, the bearing guide assembly exerts minimal additional friction on the load column in the vertical direction, thus not limiting the output of the working load and displacement of the spring support.
[0029] The limiting assembly includes a limiting plate (10) and a reinforcing plate (11). The limiting assembly is symmetrically arranged on the load plate (2). The number of limiting assemblies is 2 or 4. By setting different numbers and different orientations of limiting assemblies, radial limiting, axial limiting, or simultaneous radial and axial limiting of the pipeline can be achieved.
[0030] The radius of curvature of the concave structure of the arc-shaped rotating shaft (7) is equal to the sum of the radius of curvature of the load column (3) and the guide gap. The shape of the concave structure of the arc-shaped rotating shaft (7) matches the shape of the convex structure of the load column (3), ensuring that the arc-shaped rotating shaft (7) rolls smoothly and has a tight limit on the load column (3).

Any changes or modifications made by those skilled in the art using the above content without departing from the scope of the technical solution of this utility model should be considered equivalent examples of equivalent changes.
