Description

Technical Field

[0001] This utility model relates to the field of steelmaking equipment technology, specifically to a device for preventing molten iron ladle from tipping over. Background Technology

[0002] With the increasing size of blast furnaces and improvements in the iron and steel smelting industry in China, steel companies have implemented a new molten iron supply technology called "one ladle to the bottom." This involves a molten iron ladle being transported by train to the blast furnace to receive molten iron before being transported to the steelmaking workshop, where it is lifted by an overhead crane and directly fed into the converter for smelting. This entire process, from loading and transporting molten iron to the converter, relies heavily on the molten iron ladle. As a carrier for loading and transporting liquid molten metal, the molten iron ladle is widely used in modern steelmaking operations. Ensuring the safety of the molten iron ladle during loading and transportation is a crucial aspect that all steel companies must prioritize. The most important factor is ensuring the accurate placement of the molten iron ladle on the ladle car, preventing it from tipping over and causing serious accidents.

[0003] Currently, many steel mills are using pressure sensors and weight displays on train ladle stands to monitor whether molten iron ladles fall into the rack slots in order to eliminate this safety hazard. Although this solution can effectively solve the problem of molten iron ladles falling off-center, it is quite expensive. Given the recent downturn in the steel industry, this undoubtedly increases the burden on enterprises. Therefore, it is necessary to design a simple, effective, and low-cost solution to prevent molten iron ladles from falling off-center. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide a device to prevent molten iron ladle from tipping over.

[0005] The specific solution of this utility model is: a device for preventing molten iron ladle from falling off course, including a molten iron ladle and a transport vehicle. The lower end of the outer wall of the molten iron ladle is provided with a horizontally outward protruding support shaft. The transport vehicle is provided with a support corresponding to the position of the support shaft. The upper end of the support is provided with an arc-shaped groove that matches the support shaft. The side of the support is provided with a color mark. The outer circular surface of the support shaft is divided into an upper half and a lower half. The surface of the lower half is provided with a color mark different from that of the support. When the molten iron ladle is completely placed on the transport vehicle, the color mark of the lower half of the support shaft is completely covered by the arc-shaped groove.

[0006] Furthermore, the upper half of the outer circular surface of the support shaft is marked with the same color as the bracket.

[0007] Furthermore, the transport vehicle is equipped with lights on both sides of the support, with the lights aimed at the support and the support shaft.

[0008] Furthermore, two support shafts are provided on each side of the lower end of the outer wall of the molten iron ladle, and the two support shafts are symmetrically arranged with respect to the center line of the molten iron ladle; the support base is provided with two arc-shaped grooves, and the two arc-shaped grooves correspond one-to-one with the support shafts.

[0009] Furthermore, the surface of the support is marked with a yellow mark, and the lower half of the support shaft is marked with a red mark.

[0010] Compared with the prior art, this utility model has the following advantages: it can effectively solve the problem of preventing molten iron ladle from falling off-center, and it is low in cost and will not increase the burden on steel companies. Attached Figure Description

[0017] See Figure 1-5 This embodiment is an anti-falling device for molten iron ladles, including a molten iron ladle 1 and a transport vehicle 4. The lower end of the outer wall of the molten iron ladle 1 is provided with a horizontally outward protruding support shaft 2. The transport vehicle 4 is provided with a support seat 3 corresponding to the position of the support shaft 2. The upper end of the support seat 3 is provided with an arc-shaped groove that matches the support shaft 2. The side of the support seat 3 is provided with a color mark. The outer circular surface of the support shaft 2 is divided into an upper half and a lower half. The lower half surface is provided with a color mark different from that of the support seat 3. When the molten iron ladle 1 is completely placed on the transport vehicle 4, the color mark of the lower half of the support shaft 2 is completely covered by the arc-shaped groove.

[0018] Furthermore, the upper half of the outer circular surface of the support shaft 2 is marked with the same color as the bracket 3.

[0019] Furthermore, the transport vehicle 4 is equipped with lighting lamps 5 on both sides of the support 3, and the lighting lamps 5 are aimed at the support 3 and the support shaft 2.

[0020] Furthermore, two support shafts 2 are provided on each side of the lower end of the outer wall of the molten iron ladle 1, and the two support shafts 2 are arranged symmetrically with respect to the center line of the molten iron ladle 1; the support 3 is provided with two arc-shaped grooves, and the two arc-shaped grooves correspond one-to-one with the support shafts 2.

[0021] Furthermore, the surface of the support 3 is marked with a yellow mark 6, and the lower half of the support shaft 2 is marked with a red mark 7.

[0022] In practical application, when the molten iron ladle 1 is fully seated, as described in this utility model... Figure 2 , 3 As shown, the four support shafts 2 at the lower end of the molten iron ladle 1 are fully seated in the arc-shaped grooves of the corresponding supports 3. The red markings 7 on the lower half of the support shafts 2 are covered by the arc-shaped grooves. The supports 3 and support shafts 2 are illuminated by the lighting lamp 5 so that the workers can observe them. If the molten iron ladle 1 is not fully seated, as shown... Figure 4 , 5 As shown, the lower half of the support shaft 2 with red marking 7 is exposed. At this time, the red marking 7 and the yellow marking 6 are clearly visible to the workers, allowing them to react in time.
