Description

Technical Field

[0001] The present invention relates to a clip - type guiding support and its working method, and particularly to a clip - type guiding support with a universal ball head and its working method. Background Art

[0002] In the fields of electric power, petrochemical industry, etc., due to additional displacement and thermal expansion, thermal displacement will occur at some equipment support points, and clip - type guiding supports are usually used to support pipelines and equipment. Referring to the figure, a clip - type guiding support is a functional structural component. Firstly, it relies on the polytetrafluoroethylene plate on the bottom surface of the clip - type guiding support to increase smoothness and reduce friction. When the pipeline undergoes axial displacement, its frictional force increases with the increase in the displacement of the clip - type sliding support. Secondly, the radial displacement of the pipeline is restricted by the guiding plates on both sides.

[0003] Publication No. CN114704689A discloses a limit sliding device that can always maintain uniform force, including a limit pipe clamp, a pipeline, a limit sliding plate, a limit steel structure, and a number of universal ball heads; the limit pipe clamp is buckled on the pipeline, and the limit sliding plate is located between the limit pipe clamp and the limit steel structure. Among them, the limit sliding plate and the limit steel structure are connected by a number of suspension bolts, each universal ball head is fixed on the limit sliding plate, and each universal ball head is in contact with the limit pipe clamp; a spherical tile is arranged on the side surface of the limit sliding plate, a fixed block is arranged on the side surface of the limit steel structure, a groove matching with the spherical tile is arranged on the fixed block, the spherical tile is located in the groove, and a through - hole for the suspension bolt to pass through is arranged on the limit sliding plate. Among them, the diameter of the through - hole is larger than the diameter of the suspension bolt. By using the low - friction performance of the universal ball head, the sliding friction between steels is changed into bearing rolling friction to reduce the additional force of the pipeline. In addition, when the pipeline thermally expands, since the diameter of the through - hole on the limit sliding plate is larger than the diameter of the suspension bolt, the limit sliding plate can move unobstructed on the suspension bolt within a certain inclination angle range, so that the limit sliding plate cooperates with the spherical tile to ensure that the universal ball heads on the limit sliding plate are all in close contact with the limit pipe clamp, ensuring that the limit device is uniformly stressed when the pipeline thermally expands, with simple structure, convenient operation, and extremely strong practicability.

[0004] Due to installation problems, or wear, detachment caused by long - term operation, and the characteristics that the polytetrafluoroethylene material cannot withstand high temperatures, etc., the clip - type sliding support is damaged, resulting in an increase in the surface frictional force of the clip - type sliding support, hindering the normal axial horizontal thermal displacement of the pipeline. It may also be because the bolts of the clip - type sliding support become loose, and the radial load of the pipeline causes the clip - type guiding support to twist radially, resulting in the failure of the clip - type guiding support, causing the pipeline to be unloaded and the stress to increase. Summary of the Invention

[0005] The object of the present invention is to overcome the above-mentioned disadvantages of the prior art, and provides a clamping type guiding support with a universal ball head and its working method. The support and its working method can effectively avoid the phenomenon of hindering the normal axial horizontal thermal displacement of the pipeline, and at the same time avoid the problem of the support failure caused by the radial load of the pipeline.

[0006] To achieve the above object, the present invention discloses a clamping type guiding support with a universal ball head, which includes a pipe clamp and a sliding bottom plate. A support is arranged at the lower end of the pipe clamp, and limiting blocks are arranged on both sides of the support. Two guiding grooves are arranged on the sliding bottom plate. Among them, one guiding groove corresponds to one limiting block, and each limiting block is located in the guiding groove. A plurality of universal ball heads are arranged on the sliding bottom plate, and each universal ball head is located between the two guiding grooves. A sliding plate is arranged at the bottom of the support, and the sliding plate is located on each universal ball head.

[0007] Further, the pipe clamp includes an upper fixing member and a lower fixing member, and the upper fixing member is buckled with the lower fixing member.

[0008] Further, the upper fixing member and the lower fixing member are connected by hexagon head bolts.

[0009] Further, the limiting block includes a vertical plate and a horizontal plate. Among them, one end of the horizontal plate is connected to the side surface of the bottom of the support, and the other end of the horizontal plate is connected to the side surface of the vertical plate. The vertical plate is located in the guiding groove.

[0010] Further, the guiding groove is of a portal structure.

[0011] Further, a hole groove for the horizontal plate to pass through is arranged on the side surface of the guiding groove, and the vertical plate is located inside the portal structure.

[0012] Further, each universal ball head is distributed in a matrix.

[0013] Further, the sliding plate is a mirror surface steel plate.

[0014] The present invention discloses a working method of a clamping type guiding support with a universal ball head, which includes the following steps:

[0015] When the pipeline or equipment has an axial thermal displacement, it drives the limiting block to move in the guiding groove. At the same time, the sliding bottom plate slides on the universal ball heads, converting the sliding friction into the bearing rolling friction of the universal ball heads, which is convenient for the axial thermal displacement of the pipeline or equipment.

[0016] Further, the limiting block includes a vertical plate and a horizontal plate. Among them, one end of the horizontal plate is connected to the side surface of the bottom of the support, and the other end of the horizontal plate is connected to the side surface of the vertical plate. The vertical plate is located in the guiding groove;

[0017] The guiding groove has a U-shaped structure;

[0018] A hole groove for the transverse plate to pass through is arranged on the side surface of the guiding groove, and the vertical plate is located inside the U-shaped structure.

[0019] The present invention has the following beneficial effects:

[0020] When the pipe or equipment has an axial thermal displacement during the specific operation of the clip-type guiding support with a universal ball head and its working method according to the present invention, the sliding bottom plate slides on the universal ball head, converting the sliding chute into the bearing rolling friction of the universal ball head, facilitating the horizontal thermal displacement of the pipe or equipment. Even if the pipe clip bolts become loose and fall off, the limiting groove can, due to its own structural characteristics, prevent the pipe clip from twisting radially and the pipe from being unloaded.

Metallurgy, Petroleum, and Chemical Industries: In these industries, guide supports are used for the support of pipes or equipment, especially in places where pipe vibration and displacement need to be controlled. Bridges and Buildings: In large building structures, guide supports are used for vibration damping or sliding support to ensure the stability and safety of the structure. Pipe Systems: Guide supports are suitable for pipe supports that transmit various media (such as steam, water, gas, and oil), especially those pipes that require thermal displacement design. Automated Equipment: In automated equipment, guide shaft supports are used to fix and guide shafts, ensuring the accuracy of the transmission system.
