Description

Technical Field

[0001] This application belongs to the technical field of auxiliary equipment for metal smelting, and specifically relates to a tilting frame. Background Technology

[0002] In the metal smelting industry, tipping frames are used to place molten iron ladles and tip them under the action of a drive mechanism. In the current process of using tipping frames and molten iron ladles together, the molten iron ladles are affected by the high temperature of the molten iron, which increases their plasticity. During the process of working with the tipping frame, they are prone to deformation due to impacts, which leads to uneven stress on the tipping frame, increases the probability of damage to the tipping frame, and increases the probability of safety accidents. Summary of the Invention

[0003] To address the technical problem that tipping frames are prone to damage during the process of working with molten iron ladles, this application provides a tipping frame.

[0004] In a first aspect of this application, a tilting frame is provided, comprising:

[0005] A crossbeam, wherein the width at both ends of the crossbeam is greater than the thickness at the middle of the crossbeam;

[0006] A connector is disposed in the middle of the crossbeam, and the connector has a through hole, the axis of which is perpendicular to the crossbeam.

[0007] The beams are parallel in their length direction;

[0008] Tilting arms, two tilting arms are disposed opposite each other at opposite ends of the crossbeam, and a placement groove is provided in the middle of the tilting arms, wherein the connecting piece and the two tilting arms are respectively located on opposite sides of the crossbeam.

[0009] In some embodiments, a guide block is also provided at the top of the crossbeam, and the guide block has a first guide portion facing the side wall of the tilting arm.

[0010] In some embodiments, the first guide portion is an inclined surface, the lower edge of which connects with the top surface of the crossbeam toward the side edge of the tilting arm.

[0011] In some embodiments, a second guide portion is provided on the upper part of the placement slot near the side wall of the crossbeam.

[0012] In some embodiments, the second guide portion is an inclined surface that smoothly transitions to the sidewall of the placement groove.

[0013] In some embodiments, the tilting arm includes a connecting part, a receiving part, and a limiting part connected in sequence. The connecting part is connected to one end of the crossbeam, the placement groove is disposed in the receiving part, and the top end of the limiting part is higher than the top end of the crossbeam.

[0014] In some embodiments, the distance between the bottom of the placement groove and the bottom end of the receiving part is not less than the thickness of the connecting part.

[0015] In some embodiments, the sidewall of the crossbeam facing the tilting arm is arc-shaped, and the curvature of the sidewall of the crossbeam facing the tilting arm is less than π.

[0016] In some embodiments, the connection between the crossbeam and the tilting arm is smoothly transitioned.

[0017] In some embodiments, both the crossbeam and the two tilting arms are box girder structures.

[0018] According to one or more embodiments of this application, the width of the connection between the crossbeam and the tilting arm of the tilting frame is wider, the connection area between the crossbeam and the tilting arm is larger, and the strength of the connection between the crossbeam and the tilting arm is higher. When a molten steel ladle is installed on the tilting arm, the gravity of the molten steel ladle acts on the tilting arm and then on the crossbeam. Due to the different widths of the crossbeam along its length, the direction of force transmission on the crossbeam changes, the stress direction of the tilting arm on the crossbeam changes, and the stress concentration is reduced. That is, the torque of the tilting arm on the connection between the tilting arm and the crossbeam is reduced, which can reduce the probability of circumferential deformation of the tilting arm around the crossbeam, that is, reduce the probability of damage to the tilting frame, and thus achieve the effect of reducing the accident rate.

[0023] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1-3 According to a first aspect of this application, a tilting frame is provided for receiving molten iron ladles and tilting them under the action of a driving mechanism to realize the slag removal process of molten iron ladles. The tilting frame includes a crossbeam 1, a connecting member 2, and two tilting arms 3. The width at both ends of the crossbeam 1 is greater than the thickness at the middle of the crossbeam 1. The connecting member 2 is disposed at the middle of the crossbeam 1 and has a through hole 21. The axis of the through hole 21 is parallel to the length direction of the crossbeam 1. The two tilting arms 3 are disposed opposite to each other at opposite ends of the crossbeam 1. The middle of the tilting arms 3 is provided with a placement groove 31. The connecting member 2 and the two tilting arms 3 are respectively located on opposite sides of the crossbeam 1.

[0025] Two opposing tilting arms 3 are structural components used to support molten iron ladles. In use, the two lifting lugs of the molten iron ladle are placed in the placement slots 31, with the ladle positioned between the two tilting arms 3. To facilitate tilting, a through hole is provided at the end of the tilting arm 3 away from the crossbeam 1 to facilitate the installation of a rotating shaft. The connecting piece 2 is a structural component used to connect the drive mechanism. The through hole 21 on the connecting piece 2 is used to install a pin, so that the end of the tilting frame with the connecting piece 2 can be smoothly lifted by the drive mechanism and rotated around the rotating shaft that is rotatably connected to the tilting arm 3.

[0026] The width at both ends of the crossbeam 1 is greater than the thickness in the middle of the crossbeam 1. That is, the width at the connection between the crossbeam 1 and the tilting arm 3 is wider, the connection area between the crossbeam 1 and the tilting arm 3 is larger, and the strength of the connection between the crossbeam 1 and the tilting arm 3 is higher. When a molten steel tank is installed on the tilting arm 3, the weight of the molten steel tank acts on the tilting arm 3 and then on the crossbeam 1. Due to the different widths of the crossbeam 1 along its length, the direction of force transmission on the crossbeam 1 changes, the stress direction of the tilting arm 3 on the crossbeam 1 changes, and the stress concentration is reduced. That is, the torque of the tilting arm 3 on the connection between it and the crossbeam 1 is reduced, which can reduce the probability of the tilting arm 3 deforming around the crossbeam 1 in the circumferential direction, that is, reduce the probability of damage to the tilting frame, and thus reduce the accident rate.

[0027] In some embodiments, the sidewall of the crossbeam 1 facing the tilting arm 3 is arc-shaped. This means the width of the crossbeam 1 gradually increases from its middle to both ends, reducing the torque on the tilting arm 3 at its connection with the crossbeam 1. This makes the tilting frame less prone to damage, increases its service life, and reduces the accident rate. Furthermore, the arc of the sidewall of the crossbeam 1 facing the tilting arm 3 is less than π, while the circumferential arc of the molten iron ladle is 2π. This means that when the molten iron ladle is placed between the two tilting arms 3, the arc of the side of the molten iron ladle facing the crossbeam 1 is π, and the arc of the sidewall of the crossbeam 1 facing the tilting arm 3 is less than π. This results in a larger gap between the two ends of the crossbeam 1 and the molten iron ladle, reducing the probability of the bottom of the molten iron ladle hitting the crossbeam 1 during hoisting onto the tilting arm 3, thereby reducing the probability of damage to the tilting frame and increasing its service life.

[0028] The curvature of the side wall is less than π, which makes the side wall of the crossbeam 1 arc-shaped. At the same time, the side wall of the crossbeam 1 facing the tilting arm 3 is less likely to be hit by the molten iron ladle during the hoisting process, thereby reducing the probability of damage to the tilting frame. Of course, during use, reducing the probability of the molten iron ladle colliding with the tilting frame can also reduce the possibility of the molten iron in the ladle overflowing due to collision and turbulence, thus improving the safety of the operation.

[0029] In some embodiments, the connection between the crossbeam 1 and the tilting arm 3 is smoothly transitioned, further reducing stress concentration at some connection points between the crossbeam 1 and the tilting arm 3, and reducing the probability of damage to the tilting frame.

[0030] In some embodiments, a guide block 4 is also provided at the top of the crossbeam 1, and a first guide portion 41 is provided on the side wall of the guide block 4 facing the tilting arm 3. Specifically, the guide block 4 is a structural component with a certain anti-collision capability, and the guide block 4 can absorb the potential energy after the molten iron ladle collides with the guide block 4. The first guide portion 41 is used to abut against the bottom edge or side wall of the molten iron ladle to guide the bottom of the molten iron ladle, so that the bottom end of the molten iron ladle can smoothly enter between the two tilting arms 3 during the process of hoisting the molten iron ladle to the tilting arm 3, reducing the probability of the crossbeam 1 being hit by the molten iron ladle, reducing the accident rate, and increasing the service life of the tilting frame. Considering that the guide block 4 is easily damaged by the molten iron ladle, in some embodiments, the guide block 4 can be detachably set at the top of the crossbeam 1 by bolts, so as to facilitate timely replacement of damaged guide blocks 4.

[0031] In some embodiments, the first guide portion 41 is an inclined surface, the lower edge of which connects with the top surface of the crossbeam 1 facing the side edge of the tilting arm 3. That is, the inclined surface faces upwards towards the tilting arm 3, so as to guide the bottom end of the molten steel tank using the inclined surface. The processing of the inclined surface is simpler, which can reduce the manufacturing cost of the guide block 4. Of course, in some embodiments, the first guide portion 41 may also be an arc surface.

[0032] A second guide section 311 is provided on the upper part of the side wall of the placement slot 31 near the crossbeam 1. The second guide section 311 is used to abut against the edge of the lifting lug of the molten iron ladle to guide the lifting lug of the molten iron ladle, so that the lifting lug of the molten iron ladle can smoothly enter the placement slot 31 on the two tilting arms 3 during the process of lifting the molten iron ladle onto the tilting arm 3. This reduces the probability of the tilting arm 3 being hit by the lifting lug of the molten iron ladle, reduces the accident rate, and increases the service life of the tilting frame.

[0033] In some embodiments, the second guide portion 311 is an inclined surface that smoothly transitions into the side wall of the placement groove 31. The inclined surface guides the lifting lugs of the molten iron ladle, and the smooth transition between the inclined surface and the side wall of the placement groove 31 reduces the risk of impact. Of course, in some embodiments, the second guide portion 311 may also be an arc surface.

[0034] Please see Figure 1 The tilting arm 3 includes a connecting part 32, a receiving part 33, and a limiting part 34 connected in sequence. The connecting part 32 is connected to one end of the crossbeam 1. The placement groove 31 is provided in the receiving part 33. The top of the limiting part 34 is higher than the top of the crossbeam 1. When the drive structure drives the tilting frame to rotate, the relatively high height of the limiting part 34 can still limit the lifting lugs of the molten iron ladle.

[0035] In some embodiments, the distance between the bottom of the placement groove 31 and the bottom of the receiving part 33 is not less than the thickness of the connecting part 32. The receiving part 33 is the part that directly contacts the lifting lug of the molten iron ladle. That is, by increasing the thickness of the receiving part 33, the overall strength of the tilting arm 3 is increased, and the probability of deformation of the tilting arm 3 is reduced.

[0036] In some embodiments, the crossbeam 1 and the two tilting arms 3 are both box beam structures. The box beam structure has the characteristics of low weight and high strength, which can reduce the self-weight of the tilting frame and reduce the influence of the self-weight of the tilting arm 3 on the connection between the tilting arm 3 and the crossbeam 1, thereby reducing the probability of deformation between the tilting arm 3 and the crossbeam 1. At the same time, the reduction of the self-weight of the tilting frame can also reduce the driving pressure of the drive mechanism.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
