Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure bracket installation, in particular to a high-temperature pipeline steel structure bracket. Background Art
[0002] In the complex systems of modern industrial production, high-temperature pipelines shoulder the critical mission of transporting high-temperature media (such as steam, hot oil, and chemical raw materials), ensuring the smooth operation of various process flows. High-temperature pipeline steel structure supports are the supporting structures that maintain the stable operation of these pipelines. Currently, the widely used high-temperature pipeline steel structure supports in the industry mostly use bolts as the primary means of connection and fixing. This traditional connection method gained popularity during the initial installation phase due to its relative ease of operation, cost-effectiveness, and ease of on-site assembly and adjustment. However, with the deepening of long-term operation, many difficult-to-ignore technical issues have gradually surfaced.
[0003] Being in a vibrating environment for a long time is the primary difficulty faced by bolted brackets. In high-temperature piping systems, the medium inside the pipe flows continuously at high speed, and the resulting pulsating pressure constantly impacts the pipe wall. At the same time, the surrounding supporting pumps, compressors, fans and other operating equipment continuously transmit vibration waves to the outside. The two are intertwined, causing the bracket structure to be deeply trapped in high-frequency, long-term vibrations. Under such harsh working conditions, bolts, as rigid connecting components, are difficult to maintain the originally tightly engaged state between their threads under the action of repeated slight displacement and shear force, and loosening occurs frequently. Once the bolts are loose, the overall connection rigidity of the bracket is immediately greatly reduced, and the effective support effect on the pipeline is seriously weakened.
[0004] Furthermore, bolts are exposed to complex environmental factors for extended periods, and the protective layer on the metal surface gradually degrades under the dual pressure of corrosive media and physical wear, leading to rust and corrosion. Rusted bolts experience a sharp decline in mechanical properties and strength, making disassembly difficult, especially during the routine task of replacing insulation after extended use. Maintenance personnel are forced to use various powerful tools to remove rusted bolts, consuming considerable time and effort. Utility Model Content
[0005] The purpose of the present invention is to provide a high-temperature pipeline steel structure bracket to solve the problems raised in the above background technology.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] The support mechanism includes a main frame;

[0010] The clamping adjustment mechanism slides on the sliding mechanism to fix the high-temperature pipe and is convenient for installation and disassembly;
[0011] The limiting mechanism is fixed on the clamping adjustment mechanism and can perform limiting.
[0012] Furthermore, the sliding mechanism includes:
[0013] An arc-shaped frame fixed to the outer wall of the main frame;
[0014] There are two V-shaped frames, which are respectively fixed to the outer wall of the main frame at positions on both sides of the arc frame, and the outer wall of one end of the V-shaped frame is fixedly connected to a slide rail.
[0015] Preferably, the clamping adjustment mechanism includes:
[0016] The second slide rail is slidably plugged into the interior of the first slide rail, and a first bracket is fixedly connected between the outer walls of the two second slide rails. The inner wall of the second slide rail is provided with a square groove at the center;
[0017] The oblique block slides inside the square groove, a spring is fixedly connected between the outer wall of the oblique block and the inner wall of the square groove, and a square hole is opened on the outer wall of the oblique block.
[0018] Preferably, the clamping adjustment mechanism includes:
[0019] A square plate slides inside the second slide rail, a second bracket is fixedly connected between the outer walls of the two square plates, a toothed plate is fixedly connected to the outer wall of the square plate, and the toothed plate is plugged into and matched with the oblique block;
[0020] The spur gear rotates on the inner wall of one side of the second slide rail, and the spur gear is meshed with the tooth plate for transmission.
[0021] Preferably, the clamping adjustment mechanism includes:
[0022] The round rod slides on the second outer wall of the slide rail, the outer wall of one end of the round rod is fixedly connected with a hexagonal block, the outer wall of the round rod is fixedly connected with a cross, and the outer wall of the cross is slidably plugged with the spur gear.

[0028] Compared with the prior art, the beneficial effects of the present invention are:
[0029] 1. The clamping adjustment mechanism can fit the pipeline tightly according to the pipeline diameter, which can effectively reduce the formation of thermal bridges. By adjusting the closeness of the first and second tubes to the pipeline, the support force of the first and second tubes on the pipeline can be more evenly distributed. In a high temperature environment, the pipeline will expand thermally and the diameter will increase accordingly, and it will shrink when cooled. The appropriate closeness allows the first and second tubes to always maintain proper contact and support during the expansion and contraction of the pipeline.
[0030] 2. The clamping adjustment mechanism can move along with the pipeline, which can effectively release the thermal expansion displacement of the pipeline, allowing the pipeline to stretch and contract freely during thermal expansion and contraction, avoiding the restriction of pipeline expansion, which will generate huge thermal stress inside the pipeline. This thermal stress may cause local deformation of the pipeline, cracking of the weld, or even rupture.
[0031] 3. The tightness and stability of the second bracket can be enhanced by the limit mechanism and the inclined block. The limit of the second bracket is strengthened and the operation is simple. The components are located inside the second slide rail and have better protection, which effectively improves the service life. The limit mechanism is used to limit the bracket instead of the bolt, which effectively avoids rust that makes disassembly difficult or vibration that causes loose connection, thereby effectively improving stability.

[0042] Example 1
[0043] like Figure 1-3 As shown, in this embodiment, the clamping adjustment mechanism 300 includes the following parts: a hosting 1 310 is fixedly connected between the outer walls of the two slide rails 311, and a square groove 312 is opened at the center of the inner wall of the slide rail 311, and its inclined block 313 slides inside the square groove 312, and a spring 1 315 is fixedly connected between the outer wall of the inclined block 313 and the inner wall of the square groove 312, a square hole 314 is opened on the outer wall of the inclined block 313, and its square plate 321 slides inside the slide rail 311 and is fixed between the outer walls of the two square plates 321.

[0044] In this embodiment, personnel place the second gantry 320 on the first gantry 310, and the square plate 321 will be inserted into the inside of the second slide rail 311 along the corresponding position. Under the influence of the weight of the second gantry 320, the insulation layer of the second gantry 320 will contact the high-temperature pipe.

The components are located inside the slide rail 2 311 and have better protection, which effectively improves the service life. The limiting mechanism 400 is used to limit the positioning compared to the bolts, which effectively avoids rust that causes disassembly difficulties, or vibration that causes loose connections, and effectively improves stability.
