[0027] like Figures 1 to 3 As shown, a schematic diagram of an embodiment of a welding protection device of the present invention is used for protecting the surroundings when the first welding part 1 and the second welding part 2 are welded, and includes a smoke hood 3, which is connected to the first welding part 1 and the opening direction of the smoke hood 3 is toward the second welding part 2 to collect the smoke generated by the welding point 12 during welding, to ensure the appearance quality of the welding surroundings, such as the roof 10 or the wall, to avoid secondary maintenance work after welding, which can not only ensure construction efficiency and cost, but also avoid color difference of the surrounding roof 10 or wall due to welding or secondary maintenance, affecting the appearance quality, and reduce unnecessary high-altitude operations. The smoke hood 3 is made of flexible fire-resistant material, and the function of collecting smoke is realized through an umbrella-shaped design. The smoke hood 3 is tightly mounted on the outside of the first welding part 1 through a circular or square opening that matches the shape of the first welding part 1, which can not only ensure the smooth progress of the welding operation, but also prevent welding smoke from polluting the surrounding environment and causing abnormal appearance quality.

[0028] In this embodiment, a plurality of adjustment mechanisms are further included, each of which is rotatably connected to the first welding part 1, and the smoke hood 3 is connected to the first welding part 1 through the plurality of adjustment mechanisms. In this embodiment, the plurality of adjustment mechanisms are arranged at intervals along the periphery of the first welding part 1. For example, when the first welding part 1 is columnar, the plurality of adjustment mechanisms are arranged at intervals along the circumference of the first welding part 1; the first welding part 1 may also be a square column, etc. In this embodiment, the smoke hood 3 can adjust the opening size through the adjustment mechanism to adapt to the first welding parts 1 of different sizes, thereby ensuring the smoke collection effect during welding and reducing the risk of welding pollution.

[0029] In this embodiment, each adjustment mechanism includes a fixing rod 6 and a support rod 5 connected to the smoke hood 3, and the support rod 5 is rotatably connected to the first welding member 1 and fixed by the fixing rod 6. In this embodiment, the first welding member 1 is an embedded member arranged on the roof 10, and the smoke hood 3 opens downward and is set on a plurality of support rods 5; in other embodiments, it can also be fixed to the support rod 5 by bonding or other means, and the connection method of the smoke hood 3 and the plurality of support rods 5 can be flexibly selected based on the general technical knowledge of those skilled in the art. In this embodiment, the opening size of the smoke hood 3 is adjusted by rotating the support rod 5 with the first welding member 1, and the fixing rod 6 can be vertically arranged, one end of which is used for fixing, such as connecting to the ground, and the other end is connected to the support rod 5 to support and fix the inclination angle of the support rod 5; in this embodiment, the fixing rod 6 is tilted to support and fix the support rod 5, and its end away from the support rod 5 can be fixed to the second welding member 2 or other components, which can reduce the manufacturing length of the fixing rod 6 and reduce the manufacturing cost of the welding protection device.

[0030] In this embodiment, each adjustment mechanism further includes a first magnetic member 7, and the support rod 5 is rotatably connected to the first welding member 1 via the first magnetic member 7. Since the first welding member 1 is made of metal material, the first magnetic member 7 can be made of a magnet, and the rotatable connection method between the magnet and the support rod 5 is a prior art, which is not discussed in the present invention.

[0031] In this embodiment, each adjustment mechanism further includes a second magnetic member 8, one end of the fixing rod 6 is connected to the second welding member 2 through the second magnetic member 8, which is a movable connection in this embodiment, and the other end is movably connected to the support rod 5. Since the second welding member 2 is also made of metal material, the second magnetic member 8 can also be made of a magnet, and the connection method or movable connection method between the second magnetic member 8 and the fixing rod 6 is also a prior art, which is not discussed in the present invention.

[0032] The first magnetic part 7 and the second magnetic part 8 can ensure the stability of the installation and facilitate the operation of personnel. They can be quickly installed and disassembled, and are particularly suitable for high-altitude protection such as roofs. Not only can the secondary cleaning of the roof due to welding be avoided, but the installation and disassembly efficiency is high, the high-altitude operation time is reduced, and the safety of construction is improved.

[0033] In this embodiment, the adjustment mechanism further includes a connecting rod 4, and the two ends of the connecting rod 4 are movably connected to the support rod 5 and the fixing rod 6. In this embodiment, the connecting rod 4, the support rod 5, and the fixing rod 6 are rotatably connected to each other to form an adjustable triangular structure, which can not only adjust the opening degree of the smoke hood 3, but also ensure the stability after the opening degree is fixed. The technology and specific assembly method of the mutual rotation connection between multiple rods are existing technologies and will not be described separately in this design.

[0034] At least one of the connecting rod 4 and the fixing rod 6 is retractable to adjust the tilt angle of the support rod 5, that is, to adjust the opening size of the smoke hood 3. In this embodiment, the connecting rod 4 is retractable, and the connecting rod 4 includes a first connecting rod 41 connected to the support rod 5, a second connecting rod 42 connected to the fixing rod 6, and a connecting member 43 for connecting the first connecting rod 41 and the second connecting rod 42, and the connecting member 43 is movably connected to at least one of the first connecting rod 41 and the second connecting rod 42. In this embodiment, the first connecting rod 41 and the second connecting rod 42 are screws and have opposite rotation directions, and the connecting member 43 is a basket nut, which can be threadedly connected to the first connecting rod 41 and the second connecting rod 42 respectively.

[0035] In this embodiment, the fixed rod 6 and the support rod 5 are both rotationally connected and slidably connected. The support rod 5 is provided with a slide groove. The fixed rod 6 is rotatably provided with a ball near the end of the support rod 5. The ball is adapted to the slide groove. By adjusting the length of the connecting rod 4, the fixed rod 6 adsorbed on the second welding part 2 can be driven to rotate, and then the fixed rod 6 drives the support rod 5 to move up and down to adjust the opening size of the smoke hood 3.

[0036] On the other hand, the present invention also provides a method for using a welding protection device, comprising the following steps:

[0037] The opening size of the smoke collecting hood 3 is adjusted by the adjusting mechanism to collect smoke generated during welding, and the smoke is sucked away by the dust suction mechanism 9.

[0038] The specific working process of this embodiment is as follows:

[0039] Select a suitable smoke hood 3 according to the size of the first welding part 1. In this embodiment, the first welding part 1 is an embedded part on the preset roof;

[0040] Connect multiple support rods 5 to the smoke hood 3 and rotatably mount them on the first welding member 1 through corresponding first magnetic members 7. In this embodiment, the smoke hood 3 is made of a flexible refractory material and can be one or more mutually spliced ​​and mounted on multiple support rods 5.

[0041] Install the second welding member 2 by a lifting device or manpower. In this embodiment, the second welding member 2 is a bracket, and the height and center positioning are fixed by spot welding after the height and center positioning meet the requirements.

[0042] The fixing rod 6 is connected to the second welding member 2 through the second magnetic member 8. In this embodiment, the fixing rod 6 is adsorbed on the supporting arm through the second magnetic member 8. When the opening of the smoke collecting hood 3 needs to be adjusted, the connecting member 43 is adjusted to adjust the length of the connecting rod 4, so that the end of the fixing rod 6 close to the second welding member 2 rotates relative to the second welding member 2 and drives the supporting rod 5 to move up and down, thereby adjusting the opening of the smoke collecting hood 3 so that the opening is convenient for welding operation and can collect welding fumes;

[0043] Move the dust suction mechanism 9 to the matching position, ensure that the dust suction port is aligned with the welding port position, and turn on the dust suction mechanism 9 so that the personnel can perform welding work while removing smoke and dust. The dust suction mechanism 9 can use a movable finished equipment, such as a vacuum cleaner, to assist in the welding operation to remove smoke and dust, thereby protecting the surrounding environment and improving the working environment of the construction personnel.

[0044] After welding is completed, the welding guard can be quickly disassembled for reuse.

[0045] The present invention sets a smoke hood 3 around the embedded parts that need to be welded, collects air pollutants such as smoke generated during welding and removes them in time through the dust suction mechanism 9, so as to protect the welding surroundings such as walls or roofs, avoid smoke adsorbing the roof or walls during welding, and do not need secondary construction and cleaning, which saves time and effort. It can also avoid color difference of the roof or wall caused by secondary construction, save post-processing costs, and ensure the appearance quality. The device can be adjusted to be suitable for welding parts of different sizes to ensure the dust suction effect. The device can be quickly installed, disassembled, and reused. It has a simple structure and is made of universal materials, which can ensure the production cost. At the same time, the device is light and more convenient for high-altitude installation, such as on the roof, with high safety performance. The device can also be promoted and applied to wall or side template welding protection, and has a wide range of applicability.

[0046] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
