Description

Technical Field

[0001] The utility model belongs to auxiliary equipment for a steel slag processing procedure, in particular to a slag pot tilting device. Background Art

[0002] In the steel production process, every ton of steel smelted in the converter will produce 125kg-140kg of slag. After smelting, the molten slag needs to be dumped into a liquid slag pot and transported to the slag treatment process by a slag truck. During this process, the temperature of the slag in the slag pot is relatively high, generally 900°~1100°C. The heat conduction will burn the bottom of the slag pot red, causing the slag pot's tipping mechanism to deform under force during the tipping process when the slag pot is used to dump the slag into the slag truck (mainly the deformation of the ear seat, connecting rod, and triangular boom) and the bottom of the pot to crack, resulting in failure of the ear seat connection and the need to frequently replace the tipping mechanism components.

[0003] The tilting mechanism is processed externally, and the purchase cost of a single set is high. On average, one set is replaced every month, and the spare parts cost is high. It also affects production and consumes labor. Therefore, a slag pot tilting device is needed to solve the problem that the existing tilting mechanism is often damaged and needs to be replaced, which wastes costs and labor. Summary of the invention

[0004] The utility model aims at the defects in the prior art and provides a slag pot tilting device, which can greatly reduce the cost of spare parts and achieve cost saving and efficiency improvement.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme, including a swing arm for dumping the slag pot; the first end of the swing arm is rotatably connected to the U-shaped ear seat through a rotating shaft, and the U-shaped ear seat is welded to the slag pot body.

[0006] The second end of the swing arm is provided with a hook slot extending inward, and a first axial hole is provided at the second end of the swing arm and on both sides of the hook slot. The first axial hole is used to cooperate with the hanging shaft, and the hanging shaft passes through the first axial hole and the hook slot, and the axial fixation of the hanging shaft is achieved by a baffle.

[0007] Furthermore, the hanging shaft passes through the second end of the swing arm, and the side wall of the passing end is connected to the baffle, and the baffle is perpendicular to the axis of the hanging shaft.

[0008] Furthermore, a circular stopper is provided at one end of the hanging shaft away from the stopper, and the diameter of the circular stopper is larger than the diameter of the first shaft hole, thereby realizing axial limitation of the hanging shaft.

[0009] Furthermore, the swing arm adopts a block structure, and a second shaft hole is opened at the first end of the block structure for cooperating with the rotating shaft to realize rotational connection; the second end of the block structure is rotationally connected to the hanging shaft.

[0010] Furthermore, the U-shaped ear seat adopts a U-shaped structure, the opening of the U-shaped structure is arranged downward, and the bottom surface of the U-shaped structure is flat; one side surface of the U-shaped structure is welded to the slag pot body, and the other side surface of the U-shaped structure is an arc surface.

[0011] Furthermore, the U-shaped structure is provided with a hole which runs through the thickness direction thereof and cooperates with the rotating shaft, so as to enable the rotating shaft to penetrate therein.

[0012] Furthermore, an angle A between the bottom surface of the U-shaped structure and the corresponding side wall of the slag pot body is an obtuse angle.

[0013] Furthermore, a top piece is provided at the position where the bottom of the U-shaped mouth of the U-shaped ear seat contacts the swing arm, and the top piece is detachably connected to the bottom of the U-shaped mouth.

[0014] Compared with the prior art, the utility model has beneficial effects.

[0015] The utility model adopts a method of setting an ear seat on the side of the existing slag pot and setting a movable swing arm on the ear seat, so as to realize the side tipping of the slag pot by lifting the swing arm during operation. The setting of the swing arm can increase the force arm length when the slag pot tips over, which is conducive to dumping steel slag from the slag pot.

[0016] In addition, the swing arm is configured in a movable manner. During non-working hours, the swing arm is in a drooping state, which can reduce the overall dimensions of the slag pot and facilitate the transportation and storage of the slag pot. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to better understand the technical solution of the present utility model, a specific implementation plan is provided as follows; and the following scheme is only for illustration.

[0025] like Figure 1-5 As shown, the utility model designs an improved slag pot dumping device, the core part of which includes a swing arm 8 for dumping the slag pot body 1. The first end of the swing arm 8 is rotatably connected with a U-shaped ear seat 7 through a rotating shaft 11, wherein the U-shaped ear seat 7 is fixed to the slag pot body by welding, thereby ensuring that the swing arm 8 can perform a stable rotation relative to the slag pot body. A special structure is designed at the second end of the swing arm 8, that is, a hook notch 13 extending inward. In order to further enhance the reliability of the connection, two first axial holes are provided at the second end of the swing arm 8 and on both sides of the hook notch 13, and the main function of the two first axial holes is to cooperate with the hanging shaft 9. Specifically, the hanging shaft 9 will pass through the first axial hole and the hook notch 13, and in order to prevent the hanging shaft 9 from sliding and falling off in the axial direction, a baffle 10 is designed to realize the axial fixation of the hanging shaft 9, and the baffle 10 is installed on the side wall of one end of the hanging shaft 9 after passing through the swing arm 8, and is kept perpendicular to the axial direction of the hanging shaft 9.

[0026] Preferably, in order to increase the safety and reliability of the entire device, a circular stopper is further provided at the end of the hanging shaft 9 away from the stopper 10. The diameter of the circular stopper is specially designed to be larger than the diameter of the first shaft hole, so that an effective limit structure can be formed at the other end of the hanging shaft 9 to prevent the hanging shaft 9 from axial movement when subjected to external force, thereby ensuring that the connection between the swing arm 8 and the slag pot is more firm and stable during the entire slag pot dumping process. This design not only simplifies the operation process, but also improves the safety and efficiency of the slag pot dumping operation.

[0027] Preferably, the swing arm 8 adopts a block structure, and a second shaft hole is provided at the first end of the block structure, and the shaft hole is designed to be matched with the rotating shaft 11, so as to allow the swing arm 8 to rotate around the rotating shaft 11. At the same time, the second end of the block structure forms a rotation connection with the hanging shaft 9, ensuring the flexibility of the swing arm 8 during operation.

[0028] In addition, the design of the U-shaped ear seat 7 has also been optimized, which adopts a U-shaped structure, and the opening direction of the U-shaped structure is set downward. Such a design not only reduces the footprint of the overall device, but also the bottom surface 16 of the U-shaped structure is a plane, which helps to improve stability. More importantly, one side surface 14 of the U-shaped structure is welded to the slag pot body, while the other side surface is designed as a curved surface 15. This arc transition design reduces the existence of sharp angles, thereby reducing the risk of operators being injured by collision during use.

[0029] More preferably, in order to ensure that the rotating shaft 11 can be smoothly inserted and used in conjunction with the U-shaped ear seat 7, a hole is specially opened on the U-shaped structure in the thickness direction. The design of this hole is crucial to the correct installation of the rotating shaft 11, and also ensures that the swing arm 8 can be stably and reliably connected to the slag pot body, thereby improving the convenience and safety of the operation of the entire slag pot dumping system.

[0030] More preferably, the bottom surface 16 of the U-shaped structure and the corresponding side wall of the slag pot body have an obtuse angle A. This is conducive to increasing the contact area between the U-shaped ear seat 7 and the side of the slag pot, and is conducive to increasing the force-bearing area of ​​the U-shaped ear seat 7, thereby reducing the force pressure per unit area.

[0031] Preferably, a header piece 12 is provided at the position where the bottom of the U-shaped mouth 6 of the U-shaped ear seat 7 contacts the swing arm 8, and the header piece 12 is detachably connected to the bottom of the U-shaped mouth 6. By selecting header pieces 12 of different thicknesses, the dumping degree of the slag pot can be adjusted.

[0032] Description of the connection relationship.

[0033] 1. The U-shaped ear seat 7 is arranged at the lower part of the outer side wall of the slag pot.

[0034] 2. The U-shaped ear seat 7 and the swing arm 8 are connected via a rotating shaft 11 to achieve a rotational connection between the swing arm 8 and the U-shaped ear seat 7 .

[0035] 3. A hanging shaft 9 is provided at the other end of the swing arm 8, and the hanging shaft 9 is axially fixed by a baffle 10.

[0036] Working process.

[0037] Step 1: When the slag in the slag pot needs to be poured into the slag car, the main hook of the overhead crane is manually connected to the main lifting lug of the slag pot, and then the auxiliary hook of the overhead crane is connected to the hanging shaft through the hook slot.

[0038] Step 2: Use the overhead crane to lift the slag pot to the corresponding position on the slag car, and then drive the auxiliary hook to pull the hanging shaft (to realize the tipping process of the slag pot) so that the slag in the slag pot can be poured into the slag car one by one.

[0039] Step 3: After the slag is dumped, drive the auxiliary hook to restore the slag pot to the state before lifting (the slag pot mouth is facing upwards). Then transfer it to a suitable location by the overhead crane.

[0040] Step 4: Manually detach the main hook from the main lifting lug, and detach the auxiliary hook from the hanging shaft. At this time, the hanging shaft will automatically sag due to its own weight.

[0041] Step 5: When the swing arm is in working state, the upper end of the swing arm contacts with the ram, and the ram serves to limit the swing arm.

[0042] The tilting mechanism of the utility model adopts a fixed type, and the installation position of the U-shaped ear seat and the swing arm avoids the position of the tank bottom that is burned red by high temperature, which can greatly reduce the risk of cracking of the tank bottom. At the same time, it ensures the normal operation of the equipment and reduces the cost of spare parts.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. Therefore, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope defined by the claims of the present invention.
