Description

Technical Field

[0001] This utility model relates to the field of iron and steel smelting technology, specifically to a baking ladle based on high wear-resistant oxide-reinforced dispersion-strengthened steel. Background Technology

[0002] As a crucial piece of equipment in the steelmaking process, the ladle is primarily used to hold molten steel and prevent it from oxidizing and cooling during transportation. Furthermore, the ladle involves the application of refractory materials, and the refractory materials used for its lining significantly impact its service life and performance.

[0003] After the ladle is filled with molten steel, it needs to be lifted and transported using steel ropes and hoisting equipment. Currently, steel ladles on the market are equipped with two hoisting columns on the side wall for hoisting.

[0004] However, during hoisting, the hook of the hoisting equipment is heavy and its position is difficult to adjust. Therefore, the steel rope is usually fixed to the hoisting lug before the hook is hooked onto the steel rope for hoisting. However, the existing hoisting lug is prone to falling off when directly connected to the steel rope, which can lead to danger. Utility Model Content

[0005] In view of the shortcomings of the existing technology that sets lifting lugs on the side wall of the ladle, which cannot be fixed to the steel rope and are prone to falling off, this utility model provides a baking ladle based on high wear-resistant oxide reinforced dispersion steel.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A baking ladle based on high wear-resistant oxide-reinforced dispersion-strengthened steel includes a ladle made of high wear-resistant oxide-reinforced dispersion-strengthened steel. The ladle's side wall is equipped with lifting lugs. Each lifting lug has a first and a second hanging plate that rotate sequentially from the inside out and are spaced apart. The first hanging plate has a hanging shaft, and the second hanging plate has a hanging opening with a limiting structure. After the second hanging plate rotates, the hanging opening is hooked onto the hanging shaft, and the limiting structure seals the opening. This design, by using a structure where the hanging shaft and hanging plates cooperate to clamp the steel rope, and then locking the hanging opening with a locking structure, ensures that the steel rope is always positioned between the two hanging plates, preventing it from falling off and improving its safety during use.

[0008] Preferably, the side wall of the ladle is provided with two lifting lugs that are symmetrical about its center. Two lugs are provided for mounting two sets of steel cables on both sides for lifting.

[0009] Preferably, the hanging opening is an arc-shaped notch with its center located on the rotation center line of the second hanging plate. The opening of the hanging opening faces downwards, preventing it from falling off under stress.

[0010] Preferably, the width of the arc-shaped notch is the same as the diameter of the hanging shaft. This prevents excessive wobbling of the hanging shaft.

[0011] Preferably, the limiting structure includes a sliding frame horizontally slidable within the second mounting plate, a sliding pin vertically slidable within the second mounting plate, and a spring sleeved on the sliding pin. One end of the sliding frame passes through the second mounting plate and extends into the hanging opening. The other end of the sliding frame has an upper pressing slope, and the top of the sliding pin has a lower pressing slope that fits against the upper pressing slope. The bottom of the sliding pin passes through the second mounting plate and extends into the hanging opening, and the spring applies an upward elastic force to the sliding pin. To install the sliding frame and the sliding pin, the second mounting plate can be configured as a structure of two or three plates stacked together to form a cavity inside for the sliding frame and the sliding pin to slide.

[0012] Preferably, the sliding frame comprises four continuous sections, which extend horizontally to the right, vertically upward, horizontally to the left, and vertically downward, respectively. An upper pressing slope is located at the bottom of the fourth section, and when it moves to the right, the pressing sliding pin moves vertically downward. This is the specific structure of the sliding frame.

[0013] Preferably, the sliding pin sidewall is provided with a limiting platform and the second mounting plate is provided with an abutment platform, with the top and bottom ends of the spring abutting against the limiting platform and the abutment platform respectively. This structure is a specific structure in which the two ends of the spring abut against each other, used to make the spring apply an upward elastic force to the sliding pin.

[0014] Preferably, the side wall of the hanging opening is provided with a socket for inserting the sliding pin, and the socket is located directly below the sliding pin.

[0015] Preferably, the sliding pin has a plate-like structure with a beveled right side that is wider at the top and narrower at the bottom. The bevel in this structure facilitates the removal of the hanging shaft from the hanging opening.

[0016] Preferably, the hanger shaft is equipped with four limiting rings, two of which are located on both sides of the first hanger plate and the other two are located on both sides of the second hanger plate. The limiting rings are used to limit the axial movement of the hanger shaft.

[0017] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses a structure that combines a hanging shaft and a hanging plate to clamp the steel rope, and then uses a locking structure to lock the hanging opening. This ensures that the steel rope is always located between the two hanging plates and will not fall off, thus improving its safety in use. Attached Figure Description

Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] Example:

[0027] This embodiment uses a baking ladle based on high wear-resistant oxide-reinforced dispersion-strengthened steel, such as... Figure 1-5 As shown, it includes a steel ladle 10 made of high wear-resistant oxide-reinforced dispersion-strengthened steel. The side wall of the ladle 10 is provided with lifting lugs 20. Each lifting lug 20 has a first hanging plate 30 and a second hanging plate 40 that rotate sequentially from the inside out and are spaced apart. The first hanging plate 30 has a hanging shaft 50, and the second hanging plate 40 has a hanging opening 401 with a limiting structure. After the second hanging plate 40 rotates, the hanging opening 401 is hooked onto the hanging shaft 50, and the limiting structure closes the hanging opening 401. This design, by setting up a structure where the hanging shaft 50 and the hanging plates cooperate to clamp the steel rope, and then locking the hanging opening 401 with a locking structure, ensures that the steel rope is always located between the two hanging plates, preventing it from falling off and improving its safety during use.

[0028] Preferably, the side wall of the ladle 10 is provided with two lifting lugs 20 that are symmetrical about its center. Two lugs are provided for mounting two sets of steel cables on both sides for lifting.

[0029] Preferably, the hanging opening 401 is an arc-shaped notch with its center located on the rotation center line of the second hanging plate 40. The opening of the hanging opening 401 faces downwards, so it will not fall off when subjected to force.

[0030] Preferably, the width of the arc-shaped notch is the same as the diameter of the hanging shaft 50. This prevents excessive wobbling of the hanging shaft 50.

[0031] Preferably, the limiting structure includes a sliding frame 403 horizontally slidably disposed within the second hanging plate 40, a sliding pin 402 vertically slidably disposed within the second hanging plate 40, and a spring 4022 sleeved on the sliding pin 402. One end of the sliding frame 403 passes through the second hanging plate 40 and extends into the hanging opening 401. The other end of the sliding frame 403 is provided with an upper pressing slope 4031, and the top of the sliding pin 402 is provided with a lower pressing slope 4021 that fits against the upper pressing slope 4031. The bottom of the sliding pin 402 passes through the second hanging plate 40 and extends into the hanging opening 401, and the spring 4022 applies an upward elastic force to the sliding pin 402. To install the sliding frame 403 and the sliding pin 402, the second hanging plate 40 can be configured as a structure of two or three plates stacked together to form a cavity inside for the sliding frame 403 and the sliding pin 402 to slide.

[0032] Preferably, the sliding frame 403 comprises four continuous segments, extending horizontally to the right, vertically upward, horizontally to the left, and vertically downward, respectively. An upper pressing inclined surface 4031 is located at the bottom of the fourth segment, and when it moves to the right, it presses the sliding pin 402 to move vertically downward. This is the specific structure of the sliding frame 403. Preferably, the sliding pin 402 has a limiting platform on its side wall, and the second hanging plate 40 has an abutment platform inside. The top and bottom ends of the spring 4022 abut against the limiting platform and the abutment platform, respectively. This structure is a specific structure where the two ends of the spring 4022 abut against each other, allowing the spring 4022 to apply an upward elastic force to the sliding pin 402.

[0033] Preferably, the side wall of the hanging port 401 is provided with a socket for inserting the sliding pin 402, and the socket is located directly below the sliding pin 402.

[0034] Preferably, the sliding pin 402 has a plate-like structure with a beveled right side that is wider at the top and narrower at the bottom. The bevel in this structure facilitates the removal of the hanging shaft 50 from the hanging opening 401.

[0035] Preferably, the hanger shaft 50 is provided with four limiting rings, two of which are located on both sides of the first hanger plate 30, and the other two are located on both sides of the second hanger plate 40. The limiting rings are used to limit the axial movement of the hanger shaft 50.
