Abstract
Description
Technical Field
[0001] This application belongs to the technical field of metal smelting equipment, specifically relating to a tilting device. Background Technology
[0002] In the metal smelting industry, tilting frames are used to place molten iron ladles and drive them to tilt and pour out the molten iron. In the current process of using the tilting frame and the molten iron ladle together, the molten iron ladle is affected by the high temperature of the molten iron, which increases its plasticity. The tilting frame, which is in direct contact with the molten iron ladle, also experiences a certain degree of temperature rise. Furthermore, the tilting frame is prone to deformation due to impacts or pressure from the molten iron ladle during its rotation around the axis, which can easily lead to jamming of the tilting frame around the axis. Summary of the Invention
[0003] To address the technical problem of the tilting frame of current tilting devices becoming stuck after a period of use, this application provides a tilting device.
[0004] In a first aspect of this application, a tipping device is provided, comprising:
[0005] Tilting platform;
[0006] A tilting frame is disposed on the tilting platform. The tilting frame has a first end and a second end disposed opposite to each other. The first end of the tilting frame is rotatably connected to the tilting platform.
[0007] A limiting member is provided on the tilting platform. The limiting member can abut against the end face of the first end of the tilting frame so that the rotatable angle of the tilting frame is within a set range.
[0008] A support member is disposed at the top of the tilting platform, and the support member can abut against a predetermined position at the bottom of the first end of the tilting frame.
[0009] In some embodiments, the limiting member includes a column and a limiting plate, the column being fixedly mounted on the tilting platform, and the limiting plate being inclinedly mounted on the top of the column.
[0010] In some embodiments, the end face of the first end of the tilting frame is a plane, and the surface of the limiting plate that contacts the tilting frame is also a plane.
[0011] In some embodiments, the tilting frame includes a crossbeam and two tilting arms, the two tilting arms being disposed opposite each other at opposite ends of the crossbeam, wherein the crossbeam is located at the first end of the tilting frame; the end faces of the two tilting arms abut against the limiting member.
[0012] In some embodiments, a limit block is provided at the bottom of the first end of the tilting frame, and a limit groove that cooperates with the limit block is provided at the top of the support member.
[0013] In some embodiments, the limiting block has two inclined surfaces, which are arranged adjacent to each other, and one of the inclined surfaces faces away from the second end of the tilting frame; the limiting groove has a groove bottom and two adjacent receiving inclined surfaces, which face away from the tilting platform.
[0014] In some embodiments, the two receiving ramps smoothly transition into the bottom of the groove.
[0015] In some embodiments, the two receiving ramps transition with an arc.
[0016] In some embodiments, the bottom of the tilting platform is also provided with wheels.
[0017] In some embodiments, the tilting platform is further provided with a second drive mechanism, which can drive the traveling wheels to rotate so that the tilting platform can move.
[0018] The tilting platform provided according to one or more embodiments of this application, by setting a limiting component, allows the tilting frame to rotate only between the limiting component and the tilting platform. By limiting the rotation angle of the tilting frame, the stress of the molten iron ladle on the tilting frame can be kept within the range that the tilting frame can withstand, reducing the impact of the molten iron ladle on the tilting frame, reducing the probability of tilting frame deformation, and making it less likely for the rotatable connection between the tilting frame and the tilting platform to deform, thereby reducing the situation of the tilting frame getting stuck during rotation and improving the smoothness of the tilting operation;
[0019] By incorporating support components, the tilting frame in a horizontal position is less prone to relative displacement with the tilting platform due to collisions with the molten iron ladle. The relative position between the tilting frame and the tilting platform can closely approximate the original state of the tilting platform at the time of manufacture. Consequently, the rotatable connection between the tilting frame and the tilting platform is less prone to deformation. The tilting frame can maintain its good condition even after high-frequency use, reducing the likelihood of jamming during rotation, extending the service life of the tilting platform, and lowering the accident rate.

Detailed Implementation
[0026] 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.
[0027] Please see Figures 1-5 According to a first aspect of this application, a tilting device is provided, including a tilting platform 1, a tilting frame 2, a limiting member 3, and a supporting member 4. The tilting platform 1 is a structural member used to support the tilting frame 2 and has a strong load-bearing capacity. The tilting frame 2 is a mechanism used to support a ladle of molten iron 7. The tilting frame 2 is disposed on the tilting platform 1 and has a first end 24 and a second end 25 disposed opposite to each other. The first end 24 of the tilting frame 2 is rotatably connected to the tilting platform 1. Under normal circumstances, the tilting frame 2 is horizontally disposed on the tilting platform 1. When the tilting frame 2 rotates around the first end 24, the ladle of molten iron 7 on the tilting frame 2 tilts with the tilting frame 2 to complete the pouring operation of molten iron.
[0028] The limiting member 3 is set on the tilting platform 1. The limiting member 3 can abut against the end face of the first end 24 of the tilting frame 2 so that the rotation angle of the tilting frame 2 is within a set range. By setting the limiting member 3, the tilting frame 2 can only rotate between the limiting member 3 and the tilting platform 1. By limiting the rotation angle of the tilting frame 2, the stress of the molten iron ladle 7 on the tilting frame 2 can be kept within the range that the tilting frame 2 can withstand, reducing the impact of the molten iron ladle 7 on the tilting frame 2, reducing the probability of deformation of the tilting frame 2, and making it less likely for deformation to occur at the rotatable connection between the tilting frame 2 and the tilting platform 1. This reduces the possibility of the tilting frame 2 getting stuck during rotation and improves the smoothness of the tilting operation.
[0029] Support member 4 is located at the top of tilting platform 1. Support member 4 can abut against the bottom of the first end 24 of tilting frame 2 at a set position. That is, when tilting frame 2 is in a horizontal state, support member 4 can cooperate with the set position at the bottom of tilting frame 2 to limit the position of tilting frame 2, so that tilting frame 2 is not easy to cause relative displacement between tilting platform 1 due to collision with molten iron ladle 7. The relative position between tilting frame 2 and tilting platform 1 can approach the state of tilting platform 1 when it leaves the factory. Naturally, the rotatable connection between tilting frame 2 and tilting platform 1 is not easy to deform. Tilting frame 2 can still maintain a good state after high-frequency use, reducing the possibility of tilting frame 2 getting stuck during rotation, which can extend the service life of tilting platform 1 and reduce the accident rate.
[0030] Of course, the tilting device is also equipped with a first drive structure. The first drive mechanism is used to drive the second end 25 of the tilting frame 2 to rotate around the first section of the tilting frame 2. The first drive mechanism can be set on the tilting device, for example, the first drive mechanism is a hydraulic mechanism. The first drive mechanism can also be set outside the tilting device, for example, the first drive mechanism is a gantry hook.
[0031] In some embodiments, the limiting member 3 includes a column 31 and a limiting plate 32. The column 31 is fixedly installed on the tilting platform 1, and the limiting plate 32 is inclinedly installed on the top of the column 31.
[0032] Specifically, the column 31 is a structural component supporting the limiting plate 32. The column 31 can be a hollow rectangular column or a solid column structure. The limiting plate 32 is inclined. Therefore, in some embodiments, the upper part of the column 31 can have an arc-shaped bend 33 to better transmit force and reduce the probability of the column 31 being damaged by impact. Let the pivot 26 at the rotatable connection between the tilting frame 2 and the tilting platform 1 be the tilting pivot 26. The inclined surface 51 of the limiting plate 32 facing the tilting frame 2 is located on the path of the end face of the first end 24 of the tilting frame 2 rotating around the tilting pivot 26, so that the end face of the first end 24 of the tilting frame 2 can contact the end face of the limiting plate 32 facing the tilting frame 2. This has both a limiting effect on the tilting frame 2 and can reduce the pressure on the contact surface when the tilting frame 2 and the limiting plate 32 come into contact, reducing the possibility of deformation of the end face of the first end 24 of the tilting frame 2 or the limiting plate 32. In some embodiments, the limiting plate 32 can be detachably mounted on the top of the column 31 by means of bolts, so that operators can replace the deformed limiting plate 32 in a timely manner. Of course, in other embodiments, the limiting plate 32 can also be welded to the top of the column 31.
[0033] In some embodiments, the end face of the first end 24 of the tilting frame 2 is a plane, and the surface of the limiting plate 32 that contacts the tilting frame 2 is also a plane, so as to ensure that the end face of the first end 24 of the tilting frame 2 can contact the limiting part surface after rotation.
[0034] In some embodiments, the tilting frame 2 includes a crossbeam 21 and two tilting arms 23, which are disposed opposite to each other at opposite ends of the crossbeam 21, wherein the crossbeam 21 is located at the first end 24 of the tilting frame 2; the end faces of the two tilting arms 23 abut against the limiting member 3.
[0035] Specifically, the tilting frame 2 includes a crossbeam 21, a connector 22, and two tilting arms 23. The width at both ends of the crossbeam 21 is greater than the thickness in the middle of the crossbeam 21. The connector 22 is located in the middle of the crossbeam 21 and has a through hole 221. The axis of the through hole 221 is parallel to the length direction of the crossbeam 21. The two tilting arms 23 are located opposite to each other at opposite ends of the crossbeam 21. The middle of the tilting arm 23 has a slot for placing the lug of the molten iron ladle 7. The connector 22 and the two tilting arms 23 are located on opposite sides of the crossbeam 21.
[0036] In some embodiments, a limiting block 5 is provided at the bottom of the first end 24 of the tilting frame 2, and a limiting groove 41 that cooperates with the limiting block 5 is provided at the top of the support member 4. The cooperation between the limiting block 5 and the limiting groove 41 restricts the relative position of the tilting frame 2 and the tilting platform 1, so that when the tilting frame 2 is reset to a horizontal state, the relative position between the tilting frame 2 and the tilting platform 1 will not change due to external forces. For example, when the molten iron ladle 7 is placed on the tilting frame 2, even if the molten iron ladle 7 collides with the tilting frame 2, the first end 24 of the tilting frame 2 is restricted by the tilting platform 1, and the second end 25 of the tilting frame 2 is restricted by the limiting groove 41. The rotatable connection between the tilting frame 2 and the tilting platform 1 is not easily deformed, and the rotating shaft 26 between the tilting frame 2 and the tilting platform 1 is not easily squeezed and deformed. Naturally, the tilting frame 2 can rotate smoothly during high-frequency use, is not easily damaged, has a long service life, and reduces the accident rate.
[0037] In some embodiments, the limiting block 5 has two inclined surfaces 51, which are arranged adjacent to each other, with one inclined surface 51 facing away from the second end 25 of the tilting frame 2; the limiting groove 41 has a bottom and two adjacent receiving inclined surfaces 42, which face away from the tilting platform 1.
[0038] Understandably, one inclined surface 51 of the limiting block 5 faces away from the second end 25 of the tilting frame 2, and the two receiving inclined surfaces 42 face away from the tilting platform 1. That is, when the tilting frame 2 is set horizontally, the cross-sectional area of the limiting block 5 decreases along the direction close to the limiting groove 41, so that the end of the limiting block 5 on the rotating tilting frame 2 can smoothly cooperate with the limiting groove 41. The receiving inclined surface 42 also has a guiding function. Specifically, after the tilting frame 2 has a certain deformation, the limiting block 5 contacts the receiving inclined surface 42. Under its own weight, the limiting block 5 will fall along the receiving inclined surface 42 and eventually cooperate with the limiting groove 41. The force given to the limiting block 5 by the receiving inclined surface 42 will be transmitted to the tilting frame 2, which has a certain function of correcting minor deformation. Of course, the limiting block 5 can also provide convenience for the stirring of molten iron in the next process of metal smelting and limit the circumferential component force of the tilting frame 2.
[0039] In some embodiments, the limiting groove 41 only has a groove bottom and two receiving inclined surfaces 42, that is, the groove opening and adjacent sides of the limiting groove 41 are open, which can reduce the difficulty of the limiting block 5 cooperating with the limiting groove 41 and reduce the probability of the bottom end of the limiting block 5 directly colliding with the top end of the support member 4. Further, in some embodiments, the support member 4 has two of the above-mentioned limiting grooves 41, which are arranged opposite to each other to provide support for the opposite ends of the limiting block 5. In this case, the limiting block 5 has three inclined surfaces 51, one inclined surface 51 of the limiting block 5 faces away from the second end 25 of the tilting frame 2, and the other two inclined surfaces 51 are on its two sides, so that the limiting block 5 can cooperate with the two limiting grooves 41.
[0040] In some embodiments, the two receiving inclined surfaces 42 smoothly transition to the bottom of the groove. The arc of the transition surface guides the bottom end of the limiting block 5 and reduces impact damage. In some embodiments, the two receiving inclined surfaces 42 have an arc transition between them.
[0041] In some embodiments, the bottom of the tilting platform 1 is also provided with wheels 6. That is, the tilting platform 1 can be moved to the target position to tilt the molten iron ladle 7. Of course, the tilting platform 1 can also be used to transport the molten iron ladle 7.
[0042] In some embodiments, the tilting platform 1 is further provided with a second drive mechanism, which can drive the traveling wheels 6 to rotate so that the tilting platform 1 can move. The second drive mechanism can be a motor.
