Description
Technical Field
[0001] This utility model relates to the field of metallurgy, and in particular to a metallurgical container tilting assembly with good stability. Background Technology
[0002] Metallurgical slag containers are mainly used to hold metallurgical slag produced during metallurgical production. They are also used to hold other high-temperature metallurgical substances, such as liquid copper matte in copper smelters.
[0003] There are two main methods for tipping and dumping metallurgical slag pots. One method is to use a trolley to transport the slag pot to a designated location and then use a tipping device to dump it. The other method is to use a gantry crane to lift the slag pot to a certain location and then use a tipping device to dump it. Regardless of the method used, a tipping device or tipping assembly is required.
[0004] Tilting components are generally installed at the slag dumping point or directly on the trolley. Generally speaking, the working principle of the tilting component is to pull the bottom of the slag pot, so that the entire slag pot rotates around its trunnion, thereby achieving tilting. Tilting components are also divided into linkage type, screw type and rope type in terms of structure. Although they are different in structure, their ultimate purpose is to make the slag pot rotate around its trunnion to achieve tilting.
[0005] The aforementioned tilting components typically require a transmission connection with the slag pot. In particular, some existing tilting components have a locking structure, and the connection process is relatively time-consuming, requiring the use of multiple components to fix the trunnion position. However, since the slag pot contains high-temperature metallurgical slag, manually performing the locking connection operation is relatively risky. Summary of the Invention
[0006] To overcome the shortcomings of the prior art, this utility model aims to provide a tilting assembly that can quickly connect trunnions while having better operational stability.
[0007] The technical solution adopted in this utility model is as follows: a metallurgical container tilting assembly with good stability, including an outer support structure, a tilting drive structure, and a trunnion linkage assembly. The outer support structure is a frame-type support structure used to support the slag pot. The slag pot is hoisted into the inner side of the outer support structure using a hoisting device. The outer support structure has a support part for supporting the trunnion of the slag pot. This support part is equipped with a trunnion linkage assembly that is linked with the trunnion of the slag pot. The trunnion linkage assembly includes a ratchet and a pawl. The ratchet moves with the trunnion of the slag pot, and the pawl locks the ratchet to prevent reverse rotation. The tilting drive structure is used to drive the slag pot to rotate around its trunnion. The outer support structure includes... The system comprises a base, columns, trunnion supports, and a crossbeam. The base is fixedly mounted on a rigid surface to prevent localized settlement under the weight of the slag pot and to provide a mounting surface for other structural components. The columns are fixed to the base, and their tops are connected by a crossbeam. Two trunnion supports are spaced apart between the columns, with their bottoms fixed to the base. The slag pot is suspended between the two trunnion supports, which support the two trunnions of the pot. The upper surface of each trunnion support has a trunnion insertion groove extending from top to bottom, and the trunnion insertion grooves of the two trunnion supports are coaxially aligned.
[0008] As a further embodiment of this utility model: the tilting drive structure includes a steel rope, a pulley, and a winch. The winch and the pulley are respectively fixed on the base and the crossbeam. One end of the steel rope is wound around the drum of the winch, and the other end of the steel rope passes through the pulley and is tied to a hook. A lifting lug is provided on the outer surface of the slag pot near the bottom. The winch is used to wind the steel rope by hooking the hook to the lifting lug, thereby pulling the slag pot to tilt. At the same time, the tilting of the slag pot is a rotation around its trunnion.
[0009] As a further embodiment of this utility model: the trunnion linkage assembly includes a ratchet, a pawl, a ratchet back plate, a trunnion semi-encased tube 11, a hanging plate, and an insert strip 13. The trunnion semi-encased tube is a semi-circular tube obtained by dividing a complete circular tube along its axis into equal parts. The trunnion semi-encased tube is embedded in the corresponding trunnion embedding groove, and there is a sliding contact between the trunnion semi-encased tube and the trunnion embedding groove. One end of the trunnion semi-encased tube is fixedly connected to the ratchet via the ratchet back plate, and the other end is connected to the hanging plate 12. The ratchet back plate and the hanging plate are respectively slidably fitted against the two sides of the trunnion bracket. At the same time, the central axis of the trunnion semi-encased tube coincides with the central axis of the ratchet. When the trunnion... When the trunnion semi-encased tube rotates along the groove wall of the trunnion insertion slot, its two ends simultaneously drive the hanging plate and ratchet to rotate. The inserting strip is set axially on the inner surface of the trunnion semi-encased tube. The inserting strip is used to fit the insertion slot opened on the bottom surface of the trunnion. The trunnion of the slag pot is lowered into the trunnion semi-encased tube by hoisting, and at the same time the inserting strip is inserted into the corresponding insertion slot. When the slag pot rotates and tilts, the slag pot trunnion drives the trunnion semi-encased tube to rotate. The pawl is set below the ratchet. One end of the pawl is hinged to the trunnion bracket by a spring pin with a torsion spring. The trunnion bracket has a pin hole for the spring pin to extend into. The other end of the pawl locks the teeth of the ratchet to prevent the ratchet from reversing.
[0010] The beneficial effects of this utility model are as follows: The ratchet and pawl structure in the trunnion linkage assembly of this application prevents the slag pot from tipping over during tilting, thus improving operational safety. At the same time, the entire protective structure is simple, requiring no human intervention, reducing operational risks. The semi-enclosed trunnion design allows for quick adaptation to corresponding slag pot trunnions, demonstrating strong adaptability.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-4 In this embodiment of the present invention, a metallurgical container tilting assembly with good stability includes an outer support structure, a tilting drive structure, and a trunnion linkage assembly. The outer support structure is a frame-type support structure used to support the slag pot. The slag pot is hoisted into the inner side of the outer support structure by a hoisting device. The outer support structure is provided with a support part for supporting the trunnion of the slag pot. The trunnion linkage assembly is also provided at the support part. The trunnion linkage assembly is linked with the trunnion of the slag pot, so that the trunnion of the slag pot can drive the trunnion linkage assembly when rotating. The tilting drive structure is used to drive the slag pot to rotate around its trunnion.
[0019] The external support structure includes a base 1, columns 2, trunnion brackets 3, and a crossbeam 4. The base 1 is a rigid structure, which is fixedly installed on a rigid mounting surface. The purpose of the base 1 is to prevent local settlement when subjected to heavy pressure from the slag pot and to provide an installation base for other structural components. The columns 2 are fixed to the base 1, and the tops of the columns 2 are connected by the crossbeam 4. Two trunnion brackets 3 are provided at intervals between the columns 2, and the bottom of the trunnion brackets 3 is fixed to the base 1. By suspending the slag pot between the two trunnion brackets 3, the trunnion brackets 3 support the two trunnions of the slag pot respectively. The upper surface of the trunnion bracket 3 is provided with a trunnion insertion groove extending from top to bottom. The trunnion insertion grooves of the two trunnion brackets 3 are coaxially arranged. After the trunnion of the slag pot is inserted into the trunnion insertion groove, the trunnion bracket 3 provides support and limit for the slag pot.
[0020] The tilting drive structure includes a steel rope 5, a pulley 6, and a winch 7. The winch 7 and the pulley 6 are fixed on the base 1 and the crossbeam 4, respectively. One end of the steel rope 5 is wound around the drum of the winch 7, and the other end of the steel rope 5 passes through the pulley 6 and is fixedly tied with a hook. Since there are lifting lugs on the outer surface of the slag pot near the bottom, the hooks can be quickly hooked to the lifting lugs. The winch 7 is used to wind up the steel rope 5, which can then pull the slag pot to tilt. At the same time, the tilting of the slag pot is a rotation around its trunnion.
[0021] The trunnion linkage assembly includes a ratchet 8, a pawl 9, a ratchet back plate 10, a trunnion semi-enclosed tube 11, a hanging plate 12, and an insert strip 13. The trunnion semi-enclosed tube 11 is a semi-circular tube obtained by dividing a complete circular tube along its axis. The trunnion semi-enclosed tube 11 is embedded in the corresponding trunnion insertion groove, and there is a sliding contact structure between the trunnion semi-enclosed tube 11 and the trunnion insertion groove. One end of the trunnion semi-enclosed tube 11 is fixedly connected to the ratchet 8 through the ratchet back plate 10, and the other end of the trunnion semi-enclosed tube 11 is fixedly connected to the hanging plate 12. The ratchet back plate 10 and the hanging plate 12 are respectively slidably fitted against the two sides of the trunnion bracket 3. At the same time, the axis corresponding to the trunnion semi-enclosed tube 11 is coaxial with the ratchet 8. Therefore, it can be seen from the structure that when the trunnion semi-enclosed tube 11 rotates against the groove wall of the trunnion insertion groove, both ends of it simultaneously drive the hanging plate 12 and the ratchet 8 to rotate. A protrusion is provided on the inner surface of the trunnion semi-enclosed tube 11. An insert strip 13, parallel to the axis of the trunnion, is used to fit into an insert groove on the bottom surface of the trunnion. The trunnion is lowered into the semi-encasing tube 11 by hoisting, allowing the insert strip 13 to be inserted into the corresponding insert groove. When the entire slag pot rotates around its trunnion, the trunnion drives the semi-encasing tube 11 to rotate. A pawl 9 is located below the ratchet 8. One end of the pawl 9 is hinged to the trunnion bracket 3 via a spring pin with a torsion spring. The corresponding trunnion bracket 3 has a pin hole for the spring pin to rotate and insert. The other end of the pawl 9 engages with the ratchet 8. When the slag pot is overturned, the reverse locking structure between the ratchet 8 and the pawl 9 can prevent the slag pot from overturning, thus achieving the corresponding protection. The entire protection structure is simple and can be connected to the trunnion linkage component by hoisting, without the need for manual operation, thus providing higher safety.
[0022] Regarding the unlocking between ratchet 8 and pawl 9, that is, the reset of the slag pot after the overturning and dumping of slag, in this embodiment, a pull rope is attached to the end of the pawl 9 that contacts the ratchet 8. The pawl 9 is pulled down by the pull rope to disengage it from the ratchet 8. The pull-down drive of the pull rope needs to be implemented by installing a small winch device.
[0023] The working principle of this invention is as follows: An external support structure supports the slag pot, and a tilting drive structure drives the slag pot to tilt. When tilting is required, the tilting drive structure is operated to rotate the slag pot around its trunnion. Simultaneously, the trunnion linkage assembly is linked to the slag pot trunnion to ensure stable tilting, and the ratchet 8 and pawl 9 prevent the slag pot from overturning. The entire operation is simple and safe, requiring no manual intervention, thus improving work efficiency and safety.
[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
