Description

Technical Field

[0001] This utility model belongs to the field of petrochemicals and relates to a spring support technology, specifically, a multi-directional anti-skew device for spring supports. Background Technology

[0002] Pipe supports are an important component of piping systems, serving functions such as bearing pipe loads, limiting pipe displacement, and controlling pipe vibration. Spring supports are a crucial type of load-bearing pipe support, widely used in petrochemical plants. Due to thermal expansion and contraction, the pipe support and structural support components may experience relative thermal displacement in the vertical direction. In such cases, spring supports are required to bear the pipe load. Spring supports utilize the load-deformation characteristics of elastic support elements such as cylindrical helical springs and disc springs to support pipes experiencing vertical relative thermal displacement, preventing pipe slippage or overload, controlling the stress on pipes and equipment within a reasonable range, and ensuring the safe operation of pipelines, equipment, and installations.

[0003] In practical applications, when the pipeline and spring supports undergo horizontal relative movement, the load column is subjected to both vertical pipeline load and horizontal frictional force. This frictional force generates a rotational torque on the load column, causing it to skew. The greater the pipeline load and the greater the horizontal displacement, the lower the skew capacity of the spring supports, and the greater the likelihood of load column skew. Load column skew is a common problem. Skew can cause displacement, torsional deformation, and wear of the elastic element; jamming or even failure of the spring supports; deviation of the spring support's output load from the design value; and unpredictable changes in the pipeline stress state, affecting the safe operation of pipelines and equipment. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides an anti-skew device for spring supports and hangers, which overcomes the defects of the prior art, prevents the load column of the spring supports and hangers from skewing, and improves the stability of the spring supports and hangers.

[0005] This utility model provides an anti-skew device for a spring support, which is symmetrically arranged on both sides of the load column of the spring support. It includes a roller bearing assembly and a support assembly. The roller bearing assembly is in close contact with the load column, and the support assembly is connected to the bottom of the top plate of the spring support housing. The roller bearing assembly includes an arc-shaped roller, a bearing, and a central shaft. The concave structure of the arc-shaped roller matches the convex structure of the load column. The bearing is located inside the arc-shaped roller. Two sets of bearings are symmetrically arranged on the center line of the arc-shaped roller. The arc-shaped roller and the bearing are connected to the central shaft, and the two ends of the central shaft are fixed to the support plate.

[0006] The support components include a support plate, a vertical plate, a base plate, and a reinforcing plate.

[0007] The radius of curvature of the concave surface structure of the arc-shaped roller is equal to the radius of curvature of the load column plus the guide gap.

[0008] The bearing types include rolling bearings and sliding bearings. The main structural types of rolling bearings include tapered roller bearings, deep groove ball bearings, angular contact bearings, thrust ball bearings, cylindrical roller bearings, self-aligning ball bearings, self-aligning roller bearings, and thrust cylindrical roller bearings. The main structural types of sliding bearings include radial sliding bearings, thrust sliding bearings, and self-aligning sliding bearings.

[0009] The two ends of the central shaft of the roller bearing assembly are fixedly connected to the support plate of the support assembly. The roller bearing assembly can rotate around the central shaft axis, but cannot move along the central shaft axis.

[0010] When the working displacement of the spring support is upward, the height difference H between the multi-directional anti-skew device and the load base plate of the spring support should not be less than the design value of the working displacement of the spring support.

[0011] This utility model has the following beneficial effects:

[0012] 1) This spring support uses a multi-directional anti-skew device, which can effectively limit the horizontal displacement of the load column of the spring support, prevent the load column from skewing, and improve the stability of the spring support.

[0013] 2) The multi-directional anti-skew device has a strong bearing capacity for forces in all horizontal directions, and is particularly suitable for scenarios with large pipeline loads and large horizontal thermal displacements.

[0014] 3) This spring support uses a multi-directional anti-skew device. Taking advantage of the low coefficient of friction of the bearing rotation, the anti-skew component has a small additional frictional force on the vertical direction of the load column, and does not restrict the vertical free displacement of the load column and the working load output of the spring support.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] The implementation of the technical solution of this utility model patent will be further described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the multi-directional anti-skew device includes a roller bearing assembly and a support assembly. The multi-directional anti-skew device is symmetrically installed on both sides of the load column 2 of the spring support. The support assembly is welded to the bottom of the top plate 3 of the spring support housing. The arc-shaped rollers 5 of the roller bearing assembly are in close contact with the load column 2, preventing skewness and improving the stability of the spring support. The anti-skew device can withstand forces in multiple horizontal directions and has a strong load-bearing capacity. Therefore, it can effectively limit the horizontal displacement of the load column of the spring support, making it particularly suitable for scenarios with large pipeline loads and large horizontal thermal displacements.

[0023] The roller bearing assembly includes an arc-shaped curved roller 5, a bearing 6, and a central shaft 7; the support assembly includes a support plate 8, a vertical plate 9, a base plate 10, and a reinforcing plate 11. The bearing 6 is located inside the arc-shaped curved roller 5, and two sets of bearings 6 are symmetrically arranged on the center line of the arc-shaped curved roller 5. The arc-shaped curved roller 5 and the bearing 6 are connected to the central shaft 7, and both ends of the central shaft are fixed to the support plate 8.

[0024] The radius of curvature R1 of the concave structure of the arc-shaped roller 5 is equal to the radius of curvature R2 of the load column 2 plus the guide gap d. The shape of the concave structure of the arc-shaped roller 5 matches the shape of the convex structure of the load column 2, and the two can make good contact to ensure smooth rolling of the arc-shaped roller 5.

[0025] Bearing type 6 includes rolling bearings and sliding bearings. Specifically, you can choose tapered roller bearings, deep groove ball bearings, angular contact bearings, thrust ball bearings, cylindrical roller bearings, self-aligning ball bearings, self-aligning roller bearings, thrust cylindrical roller bearings, radial sliding bearings, thrust sliding bearings, and self-aligning sliding bearings, etc.

[0026] The two ends of the central shaft 7 of the roller bearing assembly are fixedly connected to the support plate 6 of the support assembly. The roller bearing assembly can rotate around the axis of the central shaft 7, but cannot move along the axis of the central shaft 7. Due to the small coefficient of friction of the bearing rotation, the additional friction force of the anti-skew assembly on the load column in the vertical direction is small, and it does not restrict the free vertical displacement of the load column and the working load output of the spring support.

[0027] When the working displacement of the spring support is upward, the height difference H between the multi-directional anti-skew device and the load base plate 4 of the spring support should not be less than the design value of the working displacement of the spring support, so as to ensure that the load column can freely move in the vertical direction.

[0028] The above description is merely a typical embodiment of this utility model and does not impose any limitations on this utility model. 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. Any equivalent changes made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
