Description

Technical Field

[0001] This utility model relates to the field of pipe welding auxiliary devices, and more specifically, to an automatic clamping variable diameter fixing base for vertical welding. Background Technology

[0002] The existing bases used for vertical pipe welding are all single-diameter and cannot be automatically tightened and fixed. The general fixing measures are only to weld vertical steel plates for fixing. This has little effect on fixing the pipe and is not secure. In fact, it will damage the paint layer of the pipe. When welding the pipe, it is necessary to use other machinery to provide a tightening effect on the pipe.

[0003] As people's requirements for construction become higher and higher, the demand for construction efficiency is also gradually increasing. In addition to fixing the pipes, it is also necessary to provide a clamping effect for vertical pipe welding. This requires improvements to the pipe fixing method. At the same time, a lifting mechanism needs to be added to the base to achieve the clamping effect. Therefore, there is an urgent need for a special automatic clamping variable diameter fixing base for vertical pipe welding. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose an automatic clamping variable diameter fixing base for vertical welding, which can provide clamping and fixing support for vertical pipes and can be adapted to pipes of different diameters.

[0005] To achieve this objective, the present invention adopts the following technical solution: This utility model provides an automatic clamping variable diameter fixing base for vertical welding, including a base plate and multiple fixing components. The multiple fixing components are evenly arranged on the base plate. Each fixing component includes a column, an arc-shaped clamp block, and a screw. The screw passes through the column and is rotatably connected to the arc-shaped clamp block.

[0006] In a preferred embodiment of this invention, a rubber pad is fixed to the side of the arc-shaped clamp block away from the screw.

[0007] In a preferred embodiment of this invention, the base plate is connected to a steel tray by a spring, and a plurality of fixing members are arranged around the steel tray.

[0008] In a preferred embodiment of this utility model, four fasteners are provided, and the steel tray is a rectangular plate, with the four fasteners respectively located on the four sides of the steel tray.

[0009] In a preferred embodiment of this invention, a limiting plate is provided on the screw.

[0010] In a preferred embodiment of this invention, the column is made of square tubing.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an automatic clamping variable diameter fixing base for vertical welding. The base is supported by a steel pallet, and a spring located between the base plate and the pallet provides clamping force for vertical pipe welding. The columns located around the base plate are connected by screws and arc-shaped clamps to achieve a spiral clamping function, which can effectively fix the pipe and is suitable for pipes of different diameters. The arc-shaped clamps are also equipped with rubber pads, which not only better fix the pipe but also do not damage the paint layer of the pipe wall. Attached Figure Description

[0012] Figure 1 This is a structural schematic diagram of an automatic clamping variable diameter fixing base for vertical welding provided in a specific embodiment of this utility model; Figure 2 yes Figure 1 Top view; Figure 3 yes Figure 1 Exploded view.

[0013] In the picture: Detailed Implementation The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-3 As shown in the embodiment, an automatic clamping variable diameter fixing base for vertical welding is provided, including a base plate 3 and multiple fixing components. The multiple fixing components are evenly arranged on the base plate 3. The fixing components include a column 5, an arc-shaped clamp block 8 and a screw 2. The screw 2 passes through the column 5 and is rotatably connected to the arc-shaped clamp block 8.

[0015] During welding, first, place pipe 1 vertically on the base plate 3, then adjust the various fixing components to securely clamp pipe 1. Rotate screw 2, causing it to move the arc-shaped clamp 8 towards pipe 1 until the arc-shaped clamp 8 abuts against the outer wall of pipe 1. By adjusting the fixing components in this way, pipe 1 is clamped securely, preventing displacement and ensuring a good welding result.

[0016] Furthermore, a rubber pad 6 is fixed to the side of the arc-shaped clamp 8 away from the screw 2. The rubber pad 6 makes contact with the pipe 1, which can better fix the pipe 1 and at the same time prevent the paint layer on the outer wall of the pipe 1 from being damaged.

[0017] Furthermore, the base plate 3 is connected to a steel tray 4 via springs, and multiple fasteners are arranged around the steel tray 4. The steel tray 4 is connected to the base plate 3 via springs, and the steel tray 4 supports the pipe 1. The springs can provide a certain amount of buffer support for the pipe 1, avoiding damage caused by rigid collisions when the pipe 1 is placed directly.

[0018] Furthermore, four fasteners are provided. The steel tray 4 is a rectangular plate, and the four fasteners are respectively located on the four sides of the steel tray 4. The four fasteners clamp and fix the pipe 1 from four directions, improving the fixing effect.

[0019] Furthermore, a limiting plate 7 is provided on the screw 2. The limiting plate 7 can prevent the screw 2 from rotating excessively and thus damaging or deforming the pipe 1.

[0020] Furthermore, column 5 is made of square tubing.

[0021] Other techniques in this embodiment are based on existing technologies.

[0022] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
