Description

Technical Field

[0001] This utility model relates to the field of steel pipe technology, and in particular to a durable welded steel pipe. Background Technology

[0002] Welded steel pipes, as a common type of metal pipe, have been widely used and occupy a key position in many industries due to their numerous advantages in production and processing. Their forming process is highly flexible, allowing them to be processed into different diameters, lengths, and shapes according to actual needs, adapting to various complex engineering environments. Furthermore, compared to seamless steel pipes and other types of pipes, the production process of welded steel pipes is relatively simple, and the utilization rate of raw materials is higher, resulting in lower overall costs and significant economic advantages in large-scale engineering construction.

[0003] In traditional welded steel pipe installation, gaps often appear between the pipe and the installation location due to construction errors in the installation position and dimensional deviations of the pipe itself. Traditional installation methods lack effective adjustment mechanisms and often resort to methods such as inserting hard objects or forcibly fixing the pipe to address the gap problem. This not only fails to guarantee installation stability but also easily leads to excessive local stress on the pipe, causing pipe deformation, weld cracking, and other damage, seriously affecting the service life and safety of the steel pipe.

[0004] Accordingly, this application proposes a durable welded steel pipe. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a durable welded steel pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A durable welded steel pipe includes a pipe body, on which an mounting plate is mounted. A double-threaded rod is rotatably connected inside the mounting plate. A sliding block is threaded onto the double-threaded rod. A connecting rod is hinged to the sliding block. A hinge block is hinged to the end of the connecting rod away from the sliding block. A support plate is fixedly connected to the end of the hinge block away from the connecting rod. A rotating shaft is rotatably connected to the side wall of the mounting plate.

[0008] Preferably, the rotating shaft is fixedly connected to the double-ended screw, and a rotating handle is fixedly connected to the rotating shaft, with an anti-slip strip provided on the rotating handle.

[0009] Preferably, the tube body has an inner cavity, and a spiral steel bar is provided in the inner cavity.

[0010] Preferably, the mounting plate is provided in two sets, and the mounting plate is arranged in a ring on the pipe body.

[0011] Preferably, the top of the mounting plate is provided with a groove that cooperates with the sliding of the connecting rod.

[0012] Preferably, the top of the support plate is arc-shaped.

[0013] This utility model has the following beneficial effects:

[0014] 1. The adjustment structure, consisting of a handle, shaft, double-threaded rod, sliding block, connecting rod, and other components, can adjust the support height and contact range of the support plate according to the gap between the pipe body and the installation position. This effectively eliminates the instability caused by the gap and ensures that the pipe body can be firmly fixed in various installation environments. At the same time, the support plate protects the outside of the pipe body, thereby reducing scratches and wear on the pipe body surface.

[0015] 2. The spiral steel bars inside the tube cavity utilize the continuity and torsional resistance of the spiral structure to evenly distribute external stress throughout the tube, enhancing the tube's resistance to pressure and deformation, reducing the risk of deformation and cracking, and extending its service life.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1 to 3A durable welded steel pipe includes a pipe body 1, on which an mounting plate 2 is installed. The mounting plate 2 is provided in two sets and is arranged in a ring on the pipe body 1. A double-threaded rod 21 is rotatably connected inside the mounting plate 2. A sliding block 22 is threadedly connected to the double-threaded rod 21. A connecting rod 23 is hinged to the sliding block 22. A hinge block 24 is hinged to the end of the connecting rod 23 away from the sliding block 22. A support plate 25 is fixedly connected to the end of the hinge block 24 away from the connecting rod 23. The top of the support plate 25 is arc-shaped, and the curvature of the arc matches the curvature of the outer wall of the pipe body 1, so as to achieve a tight fit with the surface of the pipe body 1. This bonding method changes the point or line stress state that may occur in traditional planar contact, and turns it into a larger area of ​​arc-shaped surface contact. This evenly distributes the pressure borne by the support plate 25 to the surface of the tube 1, avoiding excessive local pressure that could cause deformation or damage to the outer wall of the tube 1. At the same time, the support plate 25 can effectively protect the tube 1. When the tube 1 is subjected to external collision or compression, the support plate 25 can bear part of the external force in advance, reducing the risk of deformation or breakage caused by the external force acting directly on the tube 1. Moreover, this stable support state can reduce the shaking and friction of the tube 1 during use, and reduce scratches and wear on the surface of the tube 1.

[0022] A rotating shaft 26 is rotatably connected to the side wall of the mounting plate. The rotating shaft 26 is fixedly connected to a double-ended screw. A rotating handle 27 is fixedly connected to the rotating shaft 26. Anti-slip strips are provided on the rotating handle 27 to increase friction and enable the operator to hold the rotating handle 27 stably under various working conditions, avoiding operational errors caused by slippage.

[0023] The pipe body 1 has an internal cavity 11 containing a spiral reinforcing bar 12. The spiral reinforcing bar 12 is made of HRB500 grade threaded steel, and by adding alloying elements such as vanadium, niobium, and titanium, it ensures high yield strength (400MPa and above) and tensile strength while possessing excellent plasticity and toughness. When subjected to radial / axial forces, the spiral structure can uniformly disperse stress, preventing localized brittle fracture. Simultaneously, the continuity and torsional resistance of the spiral structure significantly enhance the overall compressive and deformation resistance of the pipe body 1. When the pipe body 1 is subjected to external radial or axial forces, the spiral reinforcing bar can evenly distribute the stress throughout the entire pipe body 1, preventing excessive localized stress that could lead to weld cracking or deformation of the pipe body 1. This significantly improves the service life of the steel pipe and the safety of its applicable scenarios.

[0024] The top of the mounting plate 2 is provided with a sliding groove that cooperates with the sliding of the connecting rod 23. This ensures that the connecting rod 23 can slide smoothly along the groove and also limits the connecting rod 23 laterally through the groove wall, preventing the connecting rod 23 from deviating or getting stuck during the adjustment process.

[0025] In this utility model, when the pipe body 1 is installed, if there is a gap between the pipe body 1 and the installation position, the rotating handle 27 can be rotated to drive the fixedly connected rotating shaft 26 to rotate synchronously, thereby driving the double-ended threaded rod 21 to rotate accordingly. The double-ended threaded rod 21 and the sliding block 22 are threadedly engaged, and the sliding groove at the top of the mounting plate 2 forms a rigid limit on the connecting rod 23. The rotational motion of the threaded rod is converted into the two sliding blocks 22 moving synchronously in opposite directions along the axial direction of the double-ended threaded rod or moving away from each other.

[0026] The displacement of the sliding block 22 is transmitted to the hinge block 24 through the hinged connecting rod 23, so that the support plate 25 can be raised and lowered. This adjustment process can change the support height and contact range of the support plate 25 according to the actual installation gap, thereby eliminating the instability caused by the installation gap.

[0027] The above description is only a preferred 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 technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
