[0016] In order to make the purpose, technical solution and advantages of the utility model more clear and understandable, the following preferred embodiments are cited with reference to the drawings for further detailed description of the utility model. However, it should be noted that many details listed in the specification are only for enabling the reader to have a thorough understanding of one or more aspects of the utility model, and these aspects of the utility model can be realized even without these specific details.

[0017] As Figure 1-2 shown, a movable and portable welding protection device includes a plurality of protective plates. The plurality of protective plates are arranged in parallel at the bottom of the connection of two steel beams. The plurality of protective plates are arranged across and are suction-joined to the bottom of the steel beam. The plurality of protective plates collect the welding spatter at the connection of the two steel beams. The number of protective plates is determined according to the width of the steel beam. For example, when the welding position is not wide, the required number is small. Two adjacent protective plates are in contact with each other to avoid the situation that welding spatter drops to the ground through a gap. The thickness of the color steel is 0.8 mm.

[0018] In the embodiment of the utility model, the protective plate includes a color steel plate 1, a double-layer asbestos cloth 2 and a magnetic suction device. The double-layer asbestos cloth 2 is arranged on the upper end surface of the color steel plate 1 and is attached thereto. The magnetic suction device is arranged at both ends of the color steel plate 1 and is fixedly arranged with the color steel plate 1. The magnetic suction device is suction-joined to the bottom of the steel beam. There are multiple pull rivets on the color steel for fixing the asbestos cloth and the color steel to be attached. The diameter of the iron wire or steel pipe is 5 mm.

[0019] In the embodiment of the present utility model, the magnetic attraction device includes a magnet fixing rod and a magnet. The magnet is arranged at the upper end of the double-layer asbestos cloth 2. The magnet fixing rod passes through the color steel plate 1 and the double-layer asbestos cloth 2 and is fixedly arranged with the magnet. The color steel and the asbestos cloth are closely attached to each other, and the two are fixed by a plurality of rivets. The first magnetic attraction device includes a first magnet fixing rod 3 and a first magnet 9. The first magnet fixing rod 3 fixes the first magnet 9 on the color steel plate 1. The second magnetic attraction device includes a second magnet fixing rod 4 and a second magnet 8. The second magnet fixing rod 4 fixes the second magnet 8 on the color steel plate 1.

[0020] In the embodiment of the present utility model, both sides of the color steel plate 1 are bent, and a steel wire 5 is arranged inside the bent part.

[0021] In the embodiment of the present utility model, the middle of the color steel plate 1 is provided with a groove 6. The double-layer asbestos cloth 2 is attached to the groove 6, and two iron sheets 7 are pressed on the upper end of the double-layer asbestos cloth 2 to ensure that the double-layer asbestos cloth 2 is attached. The middle part of the groove is clamped by two iron sheets to hold the asbestos cloth, and the iron sheets, asbestos cloth, and color steel are firmly fixed together by rivets to prevent the asbestos cloth in the middle part from falling down due to excessive weight. The groove 6 is set as a square groove structure.

[0022] In the embodiment of the present utility model, a number of rivets are arranged on the color steel plate 1 for fixing the double-layer asbestos cloth 2 and the color steel plate 1 to be attached to each other.

[0023] During use, this surface is adsorbed by the annular perforated strong magnet under the sides of two adjacent bottom plates to be welded. Check whether the adsorption is firm. After the check is completed, welding can be carried out. The flying welding slag during welding will be effectively blocked by the asbestos cloth.

[0024] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
