Description

Technical Field

[0001] The utility model relates to the technical field of steel plate cutting, in particular to a flame cutting device for steel plates. Background Art

[0002] After searching, it was found that in the prior art, when cutting steel plates with flame cutting devices, people would install a square frame in the ground pit, such as Figure 1 As shown, a grille is installed in the square frame, and the grille includes several partitions. When cutting the steel plate, the steel plate is moved onto the grille, and the steel plate is mounted on the partition. Then a track is laid on the steel plate, and a cutting vehicle is installed on the track. There is a flame cutting head on the cutting vehicle. The cutting vehicle moves along the track, driving the flame cutting head to move, and the steel plate is cut. The waste slag produced falls into the foundation pit through the grille.

[0003] However, in actual use, we found that the waste slag generated during cutting would splash everywhere, especially along the cutting direction of the steel plate, splashing to both sides. Moreover, not only the waste slag above the grille, but also the waste slag below the grille might splash upward out of the grille, which might splash onto the workers from the side and cause injury. Therefore, it is necessary for us to improve the above-mentioned cutting device. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a flame cutting device for steel plates, which solves the problems mentioned in the background technology.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] Compared with the prior art, the main difference of the utility model is that a slag blocking structure is installed on the grid.

[0008] Specifically in the utility model, the grid includes a plurality of rollers arranged at equal intervals, both ends of the rollers are rotatably installed between two opposite side walls of the square frame, and the highest point of the rollers is flush with the highest point of the square frame.

[0009] In order to realize the rotation of the roller, a rotating shaft is rotatably installed at the center of both ends of the roller, and the free end of the rotating shaft is fixed on the side wall of the square frame.

[0010] Specifically in the utility model, the slag blocking structure comprises two baffles arranged opposite to each other, the waist of the baffles is slidably matched with the rotating roller, and the side of the waist of the baffles is provided with a round hole, which matches the rotating roller.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the grid is composed of a plurality of rotating rollers, which makes it easier to load and unload steel plates thereon, and compared with the design of a plurality of partitions in the prior art, the utility model has a longer service life, and the slag blocking structure can shield the waste slag to prevent the waste slag from splashing and injuring workers.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 2-3 As shown, the utility model provides a flame cutting device for steel plates, comprising a square frame 1 fixedly installed in a ground foundation pit M, a grid for carrying a steel plate N is installed on the inner wall of the square frame 1, a track 2 is placed on the steel plate N, a cutting vehicle 3 is movably installed on the track 2, the cutting vehicle 3 can move on the steel plate N along the track 2, a flame cutting head 4 is installed on the cutting vehicle 3, the flame cutting head 4 comprises a cutting torch and a cutting nozzle, and cuts the steel plate N by ejecting flame, the movement of the cutting vehicle 3 on the track 2 and the flame cutting head 4 are both prior arts, and their principles are not repeated in the utility model;

[0020] like Figure 4 As shown, the main difference between the present invention and the prior art is that a slag retaining structure is installed on the grille.

[0021] like Figure 4As shown, in the utility model, the grid includes a plurality of equally spaced rollers 5 , both ends of which are rotatably mounted between two opposite side walls of the square frame 1 , and the highest point of the roller 5 is flush with the highest point of the square frame 1 .

[0022] like Figure 4 As shown, in order to realize the rotation of the roller 5 , a rotating shaft 6 is rotatably installed at the center of both ends of the roller 5 , and the free end of the rotating shaft 6 is fixed on the side wall of the square frame 1 .

[0023] like Figure 4-5 As shown, in the utility model, the slag blocking structure specifically includes two relatively arranged baffles 7-1. Here, the material of the baffle 7-1 can be melamine sponge, which can be flame retardant and can also play a role of sound insulation to prevent excessive noise from affecting the environment when the steel plate N is cut. The waist of the baffle 7-1 is slidably matched with the roller 5, and a round hole is opened on the side of the waist of the baffle 7-1, which matches the roller 5.

[0024] The working principle of the utility model is described in detail below: push the steel plate N to one side of the grille, continue to push the steel plate N, and rotate the roller 5 through the friction between the steel plate N and the roller 5. Since the two are in rotational cooperation, the friction between the two is very small, and pushing the steel plate N is more labor-saving. When the steel plate N is completely placed on the grille, place the track 2 on the steel plate N, push the baffle 7-1, and cooperate with the round hole and the roller 5 until the baffle 7-1 moves to both sides of the steel plate N. Then the cutting vehicle 3 can move along the track 2, thereby driving the flame cutting head 4 to move and cut the steel plate N. The baffle 7-1 can simultaneously block the waste slag above and below the grille to protect the workers. After the cutting is completed, similarly, the rotation of the roller 5 also facilitates the unloading of the steel plate N. Finally, after the roller 5 is used for a long time, there will be notches on its surface. By rotating the roller 5, the position of its contact with the steel plate N can be changed. Compared with the setting of the partition in the prior art, the service life is extended.

[0025] Compared with the prior art, the utility model has the following beneficial effects: the grid is composed of a plurality of rollers 5, which makes it easier to load and unload the steel plate N thereon, and compared with the design of a plurality of partitions in the prior art, the service life is longer, and the slag blocking structure can shield the waste slag to prevent the waste slag from splashing and injuring the workers.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
