Description

Technical Field

[0001] This utility model relates to the technical field of pipeline welding auxiliary devices, and in particular to a simple pipeline welding fixing bracket. Background Technology

[0002] Pipeline welding is a common and critical operation during industrial pipeline installation and maintenance. To ensure welding quality, the pipe sections to be welded must be accurately aligned and securely fixed to prevent pipe displacement due to operational vibrations or external forces during welding, which could affect welding accuracy and connection strength.

[0003] Currently, the most common fixing methods in practice are manual clamping or the use of simple mechanical clamps. However, these traditional methods have many shortcomings. First, manual clamping has poor stability, is prone to fatigue during prolonged operation, and makes it difficult to ensure stability during the welding process. Second, existing clamps are usually structurally fixed and cannot adapt to pipes of different diameters, resulting in poor versatility and increased equipment procurement and management costs. Third, most clamps are inconvenient to adjust and cumbersome to operate, affecting work efficiency. Finally, some devices are large in size, making them difficult to store and transport, occupying on-site construction space, and reducing flexibility.

[0004] Therefore, there is an urgent need to design a new type of pipe welding fixing bracket to solve the above problems, achieve rapid and stable clamping of pipes of different specifications, and have good adjustability and portability, thereby improving the safety and efficiency of welding operations. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a simple pipe welding fixing bracket to improve the stability of pipe fixing during the welding process and avoid displacement caused by vibration or external force.

[0006] The technical solution adopted in this utility model is as follows: A simple pipe welding and fixing bracket includes a workbench and support leg assemblies installed on both sides of the bottom of the workbench. The workbench has a U-shaped cross-section, with a mating plate fixed on one side of its upper surface and a positioning plate that can slide horizontally on the workbench on the other side. The positioning plate can slide towards the positioning plate and cooperate with the mating plate to clamp the side walls of the pipe on both sides. The workbench is also equipped with several top limiting components that can limit the top of the fixed pipe.

[0007] Furthermore, the support leg assembly includes a symmetrically arranged left support leg and a right support leg, the tops of the left support leg and the right support leg are welded and fixed to the bottom of the workbench, and a cross brace is welded between the left support leg and the right support leg.

[0008] Furthermore, the top surface of the workbench is symmetrically provided with a sliding groove; the bottom of the mating plate is provided with a slider, and the mating plate is slidably mounted on the top surface of the workbench via the slider; the sliding groove is also provided with a sliding control component that controls the opening and closing gap between the positioning plate and the mating plate with the slider.

[0009] Furthermore, the sliding control component includes a bolt rotatably mounted in the slide groove via a bearing. The bolt's threaded section passes through the slider at the bottom of the mating plate and is threadedly connected to the slider. Its bolt cap protrudes from the outside of one side of the worktable and is fixedly mounted with a rotating handle.

[0010] Furthermore, the top limiting assembly includes a support frame, a connecting seat, a screw, a rotating handle, and a rubber clamp; the support frame is fixedly installed on one side wall of the workbench, and the support frame is inverted L-shape, with one end extending between the mating plate and the positioning plate, and the connecting seat is fixedly welded thereto; the screw extends through between the mating plate and the positioning plate, and the screw is threadedly connected to the connecting seat; the rotating handle is fixedly installed on the top of the screw, and the rubber clamp that can fix the top of the pipeline is fixedly installed on the bottom.

[0011] Compared with the prior art, this utility model provides a simple pipeline welding and fixing bracket with reasonable structural design and easy operation, and has the following significant advantages: 1. Stable clamping and improved welding quality: The pipe sidewall is clamped by a mating plate and a sliding positioning plate, and the top of the pipe is pressed by a rubber clamp in the top limiting component, so as to achieve three-way limiting and fixing of the pipe. This effectively prevents the pipe from shifting due to vibration or external force during the welding process, thereby improving welding accuracy and connection strength.

[0012] 2. High adaptability and versatility: The mating plate can slide in the groove on the top surface of the worktable, and the distance between it and the positioning plate can be adjusted by the sliding control component to accommodate pipes of different diameters. The screw in the top limiting component can be adjusted up and down, further enhancing the adaptability to pipes of different specifications and improving the versatility of the device.

[0013] 3. Convenient operation and improved efficiency: The sliding control component uses a bolt and slider combination, and the clamping distance can be quickly adjusted by turning the handle; the top limit component adjusts the downward pressure by turning the handle, making the operation intuitive, time-saving and labor-saving, and greatly improving the efficiency of pre-welding preparation.

[0014] 4. Compact structure, easy to store and transport: The support leg assembly is fixed to the workbench by welding, and the overall structure is stable and reliable. At the same time, there are cross braces between the support legs to enhance the support stability. The workbench has a U-shaped design, which saves materials and reduces weight, making it easy to handle and set up on site.

[0015] 5. Safety protection and extended service life: The top limit component is equipped with rubber clamps at the bottom, which clamp the pipeline while avoiding damage to the pipeline wall, thus playing a good protective role. At the same time, it also reduces the wear of the clamp itself and extends the service life of the equipment.

[0016] In summary, this simple pipe welding fixing bracket not only solves the problems of poor stability, low versatility, and inconvenient adjustment of traditional manual clamping and ordinary clamps, but also has the advantages of simple structure, convenient operation, reliable clamping, and wide applicability. It is suitable for welding operations of various pipe diameters and has good promotion and application value. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Traditional pipeline welding fixing methods suffer from poor stability, low versatility, inconvenient adjustment, and large space occupation, making it difficult to meet the needs of efficient and flexible construction. This embodiment provides a simple pipeline welding fixing bracket, such as... Figure 1 As shown, the simple pipeline welding and fixing bracket includes a workbench 1 and support leg assemblies installed on both sides of the bottom of the workbench 1; the workbench 1 has a mating plate 2 and a positioning plate 3 on its cross-section, and the mating plate 2 and the positioning plate 3 form a side wall clamping structure that can clamp the side walls on both sides of the pipeline; the workbench 1 is also equipped with one or more sets of top limiting components that can limit the top of the fixed pipeline; the simple pipeline welding and fixing bracket has a simple and reliable overall structure and is easy to operate and maintain.

[0020] like Figure 1As shown, in this embodiment, the workbench 1 is a long strip plate with a U-shaped cross-section. A mating plate 2 is fixedly welded to one side of the upper surface of the workbench 1, and a positioning plate 3 that can slide horizontally on the workbench 1 is provided on the other side. Both work together to clamp the two side walls of the pipeline. Figure 2 As shown, two sliders 8 are fixedly installed at the bottom of the mating plate 2; two sliding grooves 7 are symmetrically provided on the top surface of the worktable 1 to guide the sliders 8 installed at the bottom of the mating plate 2 to slide in the sliding grooves 7, thereby adjusting the clamping width to accommodate pipes of different diameters.

[0021] Furthermore, such as Figure 2 As shown, in this embodiment, sliding control components are installed in two sliding grooves 7 respectively. Each sliding control component includes a bolt 9 rotatably mounted in the sliding groove 7 via a bearing. The bolt 9's threaded shaft 13 passes through a slider 8 at the bottom of the mating plate 2, and the bolt 9 is threadedly connected to the slider 8. Its bolt cap protrudes from the outside of one side of the worktable 1, and a rotating handle 10 is fixedly installed thereon. When the rotating handle 10 is rotated, because the slider 8 is threadedly connected to the bolt 9, and the slider 8 is limited by the inner wall of the sliding groove 7, the slider 8 can drive the mating plate 2 to move back and forth, thereby adjusting the clamping gap between the positioning plate 3 and the mating plate 2, achieving rapid and precise clamping.

[0022] like Figure 1 As shown, the top limiting component in this embodiment includes an inverted L-shaped support frame 11, one end of which extends above the clamping area and a connecting seat 12 is welded to the end. A screw 13 extends through the mating plate 2 and the positioning plate 3, and is threadedly connected to the connecting seat 12. A rotating handle 14 is fixedly mounted on the top of the screw 13, and a rubber clamp 15 is fixedly mounted on the bottom of the screw 13. The height of the rubber clamp 15 can be adjusted by rotating the handle to press it firmly against the top of the pipeline, preventing displacement during welding. The design of the rubber clamp 15 also provides cushioning protection, preventing damage to the pipe wall.

[0023] like Figure 1 As shown, the support leg assembly in this embodiment consists of a symmetrically arranged left support leg 4 and a right support leg 5. The tops of the left support leg 4 and the right support leg 5 are welded and fixed to the bottom of the workbench 1. A cross brace 6 is welded between the two support legs to enhance the overall structural stability and load-bearing capacity.

[0024] The working principle of this simple pipeline welding and fixing bracket is as follows: In use, place the pipe to be welded on the workbench 1, positioning it between the mating plate 2 and the positioning plate 3. Then, the operator simultaneously rotates the handles 10 of both sets of sliding control components with both hands, bringing the mating plate 2 closer to the positioning plate 3 until the mating plate 2 and positioning plate 3 clamp the two side walls of the pipe. Next, rotate the handle of the top limiting component to press down and press the rubber clamp 15 tightly against the top of the pipe, achieving three-way fixation of the pipe. After three-way fixation, one end of the pipe extends to the outside of the simple pipe welding fixing bracket, allowing it to be butt-welded to another pipe.

[0025] Because the mating plate 2 can slide on the top surface of the workbench 1, the distance between the mating plate 2 and the positioning plate 3 is adjustable, thus flexibly adapting to the clamping of pipes of different diameters and improving versatility. This simple pipe welding fixing bracket significantly improves clamping stability through a dual fixing method of clamping the pipe sidewall and pressing the top, effectively preventing displacement during the welding process and solving the problem of poor stability of traditional manual clamping or fixed clamps. At the same time, the sliding control component and the top limiting component are easy to operate, improving the efficiency of pipe fixing and subsequent welding. The overall structure of this simple pipe welding fixing bracket is compact, easy to store and transport, and meets the diverse needs of on-site construction.

[0026] The basic principles, main features, and advantages of this utility model are shown and described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
