Description

Technical Field

[0001] This utility model relates to an adjustable steel structure support. Background Technology

[0002] Long-distance steam pipelines, as core infrastructure for energy transmission, are widely used in industrial sectors such as power, chemical, and metallurgy, as well as urban centralized heating systems. To ensure the safe and stable operation of the pipelines, they need to be supported by overhead supports to balance multiple loads, including the pipeline's own weight, the weight of the steam medium, the additional force generated by temperature deformation, and wind loads. This prevents safety accidents such as leaks at connections and fatigue fractures caused by excessive settlement, displacement, or vibration.

[0003] However, the laying routes of long-distance steam pipelines often traverse complex terrain with significant elevation changes. This necessitates adjusting the height of each steel column along the route according to the actual terrain. Traditional steel columns are fabricated as a single unit, making it difficult to precisely match the elevation requirements of each location. This not only increases processing difficulty and cost but also leads to insufficient elevation control accuracy during on-site installation. Consequently, it affects the overall slope and stress state of the pipeline, posing a potential threat to the long-term safe operation of the steam pipeline. Utility Model Content

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-6 As shown, the adjustable steel structure support provided in this embodiment includes a fixed tube 1, an adjusting tube 2 sleeved on the outside of the fixed tube 1, multiple sets of fixed holes 3 spaced apart along its height direction on the fixed tube 1, a set of adjusting holes 4 corresponding to the position of the fixed hole sets 3 on the bottom surface of the adjusting tube 2, a support plate 5 at the top of the adjusting tube 2, an internally threaded tube 6 on the support plate 5, adjusting discs 7 spaced apart above the support plate 5, and adjusting screws 8 threadedly connected to the internally threaded tube 6 on the bottom surface of the adjusting discs 7.

[0025] The bracket achieves dual height adjustment. Coarse adjustment is completed by the corresponding insertion of the fixing hole group 3 and the adjusting hole group 4, and fine adjustment is completed by the thread engagement of the adjusting screw 8 and the internal thread tube 6. The combination of dual adjustment can meet the height requirements in different scenarios and has a wide range of applications.

[0026] A reinforcing rib can be provided at the connection between the adjusting disc 7 and the adjusting screw 8 to provide connection strength.

[0027] In this embodiment, as Figure 4 and Figure 5 As shown, the inside of the fixed tube 1 is provided with an inner liner tube 9, and the inner liner tube 9 is provided with a guide hole group 10 corresponding to the position of the fixed hole group 3. The outer wall of the inner liner tube 9 is provided with a guide tube 11 between the guide hole group 10 and the fixed hole group 3.

[0028] The guide tube 11 can guide the plug-in used for fixing, ensuring that the plug-in passes through the fixing hole group 3 and the guide hole group 10 quickly and accurately, improving the installation and adjustment efficiency; the inner liner tube 9 can enhance the structural strength of the fixing tube 1, avoid deformation at the fixing hole group 3 due to repeated plugging and unplugging of the plug-in, and extend the service life of the bracket.

[0029] A base plate is provided on the bottom surface of the fixed pipe 1 and the inner lining pipe 9, and the fixed pipe 1 and the inner lining pipe 9 are fixed on the base plate for easy installation.

[0030] The length and width of the inner liner tube 9 are greater than the diameter of the internally threaded tube 6, which will not affect the normal adjustment of the regulating tube 2.

[0031] In this embodiment, as Figure 1 As shown, both the fixed tube 1 and the adjusting tube 2 are square tubes. The fixing hole group 3 includes a first-direction fixing hole 301 and a second-direction fixing hole 302 at different height positions. The first-direction fixing hole 301 passes through the front and rear sides of the fixed tube 1, and the second-direction fixing hole 302 passes through the left and right sides of the fixed tube 1. When fixing, the double-ended screw passes through the corresponding fixing hole group 3 and adjusting hole group 4 from the front and rear and left and right directions of the fixed tube 1, respectively, and is tightened with washers and nuts at both ends of the double-ended screw, so that the adjusting tube 2 can be locked from multiple directions, improving stability and flexibility.

[0032] In this embodiment, as Figure 4 As shown, each group of first-direction fixing holes 301 and second-direction fixing holes 302 are provided with two. The two first-direction fixing holes 301 and second-direction fixing holes 302 are distributed at intervals on the front and rear and left and right sides of the fixing tube 1, respectively. The double hole setting can increase the number of plug-in parts, further improve the connection strength between the adjusting tube 2 and the fixing tube 1, distribute the force, and avoid damage to a single plug-in part due to excessive load.

[0033] In this embodiment, as Figure 1 As shown, a support telescopic tube 12 is provided between the support plate 5 and the adjusting plate 7, and a support spring 13 is provided on the inner side of the support telescopic tube 12. The support spring 13 can provide upward support force, assist the adjusting screw 8 in bearing the load above, reduce the force on the adjusting screw 8, and prevent the adjusting screw 8 from deforming or breaking due to overload.

[0034] In this embodiment, as Figure 2 As shown, the support telescopic tube 12 includes a lower fixed part 1201 and an upper moving part 1202 inserted into the inner side of the lower fixed part 1201. The bottom surface of the lower fixed part 1201 is fixed to the top surface of the support plate 5, and the top surface of the upper moving part 1202 abuts against the bottom surface of the adjusting plate 7. The two ends of the support spring 13 are respectively fixed to the top surface of the support plate 5 and the inner bottom surface of the upper moving part 1202. The support telescopic tube 12 can be flexibly extended and retracted to adapt to the up and down movement of the adjusting plate 7. The upper moving part 1202 abutting against the bottom surface of the adjusting plate 7 can make the supporting force more evenly transmitted to the adjusting plate 7.

[0035] In this embodiment, as Figure 1As shown, four support telescopic tubes 12 are provided. The four support telescopic tubes 12 are evenly distributed between the support plate 5 and the adjusting plate 7 and along the circumference of the adjusting plate 7, which can make the force on the adjusting plate 7 more uniform and further improve the horizontal stability of the adjusting plate 7.

[0036] In this embodiment, as Figure 4 and Figure 6 As shown, a guide post 14 is provided on the outer wall of the fixed tube 1 along its height direction, and a guide groove 15 is provided on the inner wall of the adjusting tube 2 to cooperate with the guide post 14. This allows for precise guidance of the up-and-down movement of the adjusting tube 2, ensuring that the adjusting tube 2 remains coaxial with the fixed tube 1 during movement and preventing deviation. Simultaneously, the guiding structure further restricts the circumferential rotation of the adjusting tube 2, forming a double anti-rotation structure in conjunction with the bidirectional fixing hole group 3, thereby improving the structural stability of the support.

[0037] In summary, in this embodiment, the adjustable steel structure bracket provides a coarse height adjustment through the combination of holes in the fixing tube 1 and the adjusting tube 2, and a fine adjustment through the threaded connection between the adjusting screw 8 and the internally threaded tube 6, meeting the height requirements of different scenarios. The square tube structure, the bidirectional fixing hole group 3, and the cooperation of the guide post 14 and the guide groove 15 effectively prevent the circumferential rotation and offset of the adjusting tube 2; the inner liner tube 9 and the guide tube 11 improve the structural strength and insertion efficiency at the fixing holes; the supporting telescopic tube 12 and the built-in supporting spring 13 enhance the horizontal stability of the adjusting plate 7, resulting in a stable overall structure and a wide range of applications.

[0038] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
