Description

Technical Field

[0001] The utility model belongs to the technical field of cast pipe production, and in particular relates to a molten iron tank cover device with adjustable height. Background Art

[0002] In the metallurgical cast pipe industry, the distance between each process is very far due to the influence of the terrain of the production area and the design of the plant. Molten iron needs to be transported by train. The molten iron and molten steel produced by smelting cast pipes need to be transported by special containers and vehicles. In order to reduce the heat loss of empty and hot ladles in transportation in the existing water collection, and the problem of easy leakage, which causes the quality of the subsequent process of molten iron to decline, in solving the above problems, the molten iron tank is wrapped to prevent its temperature from losing easily and leaking easily. However, due to the transportation problem in this process, it is inevitable that there will be rugged roads, which will cause the molten iron to be extremely unstable, produce drastic energy effects, and cause the molten iron to be ejected from the molten iron tank under high pressure, posing some safety hazards.

[0003] To this end, a high temperature resistant, foldable, movable train transport molten iron tank cover device with announcement number "CN210254218U" is disclosed, and its structure includes a molten iron tank car body, a mobile trolley, a covering hydraulic cylinder, a mobile hydraulic cylinder, a telescopic rod and a folding cover plate.

One end of the telescopic rod is connected to the covering hydraulic cylinder, and the other end is connected to a semicircular folding cover plate. The telescopic rod drives the folding cover plate to open or fold, and two opposite semicircular folding cover plates form a circular cover plate covering the tank mouth of the molten iron tank car body. The device has a reasonable structure, reduces the heat loss of molten steel or molten iron during transportation, reduces environmental pollution, and the tank cover can be folded and placed when not in use to reduce the occupied space.

[0004] However, for the above-mentioned high-temperature resistant, foldable, movable train transportation molten iron tank cover device, although the opening and closing of the cover is controlled by a hydraulic cylinder to prevent the heat loss of the molten iron or molten steel in the molten iron tank during transportation and reduce environmental pollution, there are still the following obvious defects during use: since the above-mentioned tank cover is opened and closed by the control of a hydraulic cylinder, and the tank cover has a fixed opening and closing height and angle, since there is no height adjustment component for the tank cover, the tank cover cannot be used on molten iron tanks of different heights according to the height of the molten iron tank.
