The spark - splash - proof device 1 includes a three - sided baffle 1 - 1, an upper cover plate 1 - 2, a connecting strip 1 - 3, a connecting hook 1 - 4, a handle 1 - 5, a cutting torch hook 1 - 6 and a lifting lug storage hopper 1 - 7.

[0030] As Figure 2As shown in the figure, three-sided baffle 1-1 is vertically arranged around the lug 3 to be cut off. The three-sided baffle 1-1 includes a first baffle 1-11, a second baffle 1-12 and a third baffle 1-13. Among them, the first baffle 1-11 and the third baffle 1-13 are arranged parallel to each other, and the second baffle 1-12 is vertically arranged between the first baffle 1-11 and the third baffle 1-13. The open side of the three-sided baffle 1-1 is convenient for the operator to use the cutting torch 5 to cut off the lug 3.

[0031] During the process of using the cutting torch 5 to cut off the lug 3, sparks will fly in all directions, and the three-sided baffle 1-1 can block the main lateral splashes. The anti-spark splash device provided by the present utility model is also provided with an upper cover plate 1-2. The upper cover plate 1-2 is fixed between the tops of the first baffle 1-11 and the third baffle 1-13, which can avoid the sparks flying out from the upper part driven by the air flow while not affecting the flame cutting operation.

[0032] In this embodiment, the three-sided baffle 1-1 is formed by bending a thin steel plate to form the first baffle 1-11, the second baffle 1-12 and the third baffle 1-13 that are perpendicular to each other. Of course, those skilled in the art can also choose to weld three thin steel plates into a whole according to the actual situation. In this embodiment, the upper cover plate 1-2 is also a thin steel plate, and both ends of the upper cover plate 1-2 are fixed to the tops of the first baffle 1-11 and the third baffle 1-13 by rivet connection. Of course, both ends of the upper cover plate 1-2 can also be directly fixed to the tops of the first baffle 1-11 and the third baffle 1-13 by welding. The width of the upper cover plate can be selected according to the actual situation.

[0033] In order to improve the overall stiffness of the anti-spark splash device 1, the present utility model is provided with a connecting strip 1-3 on the open side of the three-sided baffle 1-1. The connecting strip 1-3 can be made of thin steel plate, and both ends of the connecting strip 1-3 are fixedly connected to the bottom inner walls of the first baffle 1-11 and the third baffle 1-13 respectively, and can be connected by rivets or welding.

[0034] The anti-spark splash device 1 provided by the present utility model is fixed on the upper surface of the steel beam 2 where the lug 3 to be cut off is located through the connecting hook 1-4. As Figure 3 shown, the connecting hook 1-4 provided in this embodiment includes a horizontal part and a hook part.
