Description

Technical Field

[0001] This utility model relates to the field of aluminum processing, and in particular to a mobile trolley for furnace purging pipes. Background Technology

[0002] Aluminum processing companies use furnaces to melt aluminum. Before and during use, the furnace chamber needs to be purged using a purge pipe inserted into the purge inlet.

[0003] Due to the high temperature in the furnace, the purging pipe used is quite long. Manually handling the purging pipe is labor-intensive. Furthermore, because of the long length of the purging pipe, the nozzle end of the purging pipe wobbles significantly, making it difficult to insert into the furnace in one go and requiring multiple attempts. In addition, there is a risk of high-temperature material being ejected during the purging process, which can easily cause serious bodily injury to the operators.

[0004] Therefore, how to design a device to assist operators in efficiently and safely inserting the purge pipe into the furnace is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] It also includes a protective structure, which includes a mounting frame in which a transparent plastic plate is embedded and fixed to the vehicle frame by a bracket.

[0008] There is a gap between the lower edge of the mounting frame and the vehicle frame.

[0009] The frame includes two parallel, spaced-apart channel steels with their openings facing outwards. The two channel steels are welded together by multiple connecting beams to form a whole. These connecting beams are evenly spaced along the length of the frame, and the connecting beam at the rear end forms a handle.

[0010] The U-shaped bracket is welded to the middle of the corresponding connecting beam.

[0014] 2. The mobile trolley further comprises a protection structure, the protection structure comprises a mounting frame, a transparent plastic plate is embedded in the mounting frame, and the mounting frame is fixed on the frame by a support, so that the observation demand of the operator can be met, and the risk of the operator being injured by high-temperature substances sprayed from the hearth is eliminated.

[0015] 3. The frame comprises two parallel and spaced channel steels, the openings of the two channel steels are outward, and the two channel steels are integrally welded by a plurality of connecting beams, the connecting beams are uniformly and spacedly distributed along the length direction of the frame, and the connecting beam at the rear end forms a handle, so that the frame has the advantages of simple structure, high structural strength, and convenient one-handed operation of the operator, and the efficiency is effectively improved.
