Description

Technical Field

[0001] The invention relates to the field of converter smelting, and in particular to a slag pot tilter mechanism. Background Art

[0002] Converter smelting is the process of adding scrap steel to high-temperature molten iron for smelting. When the converter has discharged the molten steel, the remaining red slag is poured into the slag pot. Then, the slag pot is lifted by a crane and placed on a tilting device to pour the red slag in the pot into a drum for processing. Depending on the process of slag, the temperature of the slag can be as high as 1200-1400℃.

[0003] The slag treatment drum is a converter slag treatment equipment. The drum slag treatment production process is to collect the high-temperature liquid slag produced by the converter in the slag pot and then pour it into the rotating drum. After being cooled by water spray and crushed by steel balls in the drum, solid steel slag with uniform particles and room temperature is formed. The entire production process realizes a clean production mode without slag falling to the ground.

[0004] When the tailings in the slag pot need to be turned over, it is lifted by the crane. In order to tilt the slag pot, the auxiliary hook of the crane must lift the slag pot tilter, and the function of tilting the slag pot is achieved by raising the auxiliary hook. In the production process, in order to prevent the tilter from falling off during normal use, a metal pin is usually inserted between the tilter and the rod seat. Before the slag pot is turned over, the crane operator must first pull out the pin, and then plug it in after turning over the red slag. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an oil tank tipper structure which is simple to operate and can be applied to unmanned driving operations.

[0006] The present invention proposes a slag pot tilter mechanism, comprising a lifting rod rotatably connected to the slag pot and a locking mechanism for locking the lifting rod; the locking mechanism comprises a fixing portion arranged on the lifting rod, a rod seat arranged on the outer side wall of the slag pot and a locking hook rotatably arranged on the outer side wall of the slag pot; the fixing portion rests on the rod seat, the locking hook comprises a hook portion, and the hook portion is provided with a limiting groove opening downward; when the locking mechanism locks the fixing portion, the locking hook rests on the top of the fixing portion, and the fixing portion is located in the limiting groove.

[0007] Preferably, the rotation point of the lifting rod is arranged on the outer side wall of the slag pot, and the rotation point of the lifting rod is close to the bottom of the slag pot.

[0008] Preferably, a rotating rod is provided at the bottom of the slag pot, one end of the rotating rod is rotatably connected to the bottom of the slag pot, and the other end of the rotating rod is rotatably connected to the lifting rod.

[0009] Preferably, the outer side wall of the slag pot is provided with a rotating column, and the rotating column is rotatably connected to the slag pot seat.

[0010] As described above, the slag pot tilting device according to the present invention has the following beneficial effects:

[0011] In the present invention, the locking mechanism includes a fixed part arranged on the lifting rod, a rod seat arranged on the outer wall of the slag pot and a locking hook rotatably arranged on the outer wall of the slag pot; when the lifting end of the lifting rod is lifted upward, the fixed part on the lifting rod moves toward the slag pot, gradually disengages from the limiting groove, and presses against the locking hook, gradually causing the hook to rotate toward the slag pot. After reaching a certain position, the locking hook completely disengages from the fixed column due to gravity, and rotates to the bottom of the rod seat, thereby realizing automatic unlocking of the locking mechanism of the slag pot tilter mechanism during the tilting process. The locking mechanism has a simple structure and effectively avoids damage to the operator during manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0019] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of the relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0020] like Figures 1 to 4 As shown, an embodiment of the present invention provides a slag pot tilter mechanism, including a lifting rod 200 rotatably connected to the slag pot 100 and a locking mechanism for locking the lifting rod 200; the locking mechanism includes a fixing portion 210 arranged on the lifting rod 200, a rod seat 220 arranged on the outer wall of the slag pot 100 and a locking hook 230 rotatably arranged on the outer wall of the slag pot 100; the fixing portion 210 rests on the rod seat 220, and the locking hook 230 includes a hook portion 231, and the hook portion 231 is provided with a limiting groove 232 with an opening facing downward; when the locking mechanism locks the fixing portion 210, the fixing portion 210 is located in the limiting groove 232.

[0021] For the sake of convenience, it can be assumed that when the slag pot 100 is in the slag receiving state, the opening of the slag pot 100 faces upward, and at this time, the length direction of the lifting rod 200 is roughly parallel to the outer wall of the slag pot 100. The fixing portion 210 is located on the rod seat 220, and the hook portion 231 substantially limits the fixing portion 210 in the limiting groove 232 along the direction from top to bottom. In this embodiment, the fixing portion 210 is a fixing column.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, when the slag pot 100 starts to be tipped, the lifting end 201 of the lifting rod 200 is connected to the assistant of the driving vehicle and is lifted upwards. At this time, the slag pot 100 tips over to one side. During the tipping process of the slag pot 100, the fixed part 210 on the lifting rod 200 moves toward the slag pot 100, gradually disengages from the limiting groove 232, and presses against the locking hook 230, gradually causing the hook part 231 to rotate toward the slag pot 100. After reaching a certain position, the locking hook 230 completely disengages from the fixed part 210 due to gravity, and rotates to the bottom of the rod seat 220, thereby realizing the automatic unlocking of the locking mechanism of the tilting mechanism of the slag pot 100 during the tipping process.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, preferably, the outer side wall of the slag pot 100 is provided with a rotating column 110, and the rotating column 110 is rotatably connected to the slag pot seat 400. In the process of tipping the slag pot 100, it is only necessary to lift the lifting rod 200 located on one side of the slag pot 100. In the process of lifting the lifting rod 200, the slag pot 100 can rotate around the rotating column 110 until the opening of the slag pot 100 rotates from upward to downward, thereby realizing the tipping of the slag pot 100.

[0024] In order to save effort during the tipping process, the rotation point of the lifting rod 200 is set on the outer wall of the slag pot 100, and the rotation point of the lifting rod 200 is close to the bottom of the slag pot 100. Preferably, a rotating rod 300 is provided at the bottom of the slag pot 100, one end of the rotating rod 300 is rotatably connected to the bottom of the slag pot 100, and the other end is rotatably connected to the lifting rod 200. In this embodiment, the connection between the rotating rod 300 and the bottom of the slag pot 100 is roughly located on the symmetric plane of the pot body. When the slag pot 100 is tipped, the lifting rod 200 is continuously lifted upward, and the slag pot 100 is first adjusted from vertically upward to the horizontal orientation of the pot mouth of the slag pot 100.

[0025] During this process, the fixed portion 210 on the lifting rod 200 moves toward the slag pot 100, gradually disengages from the limiting groove 232, and abuts against the lower end surface of the locking hook 230, gradually causing the hook portion 231 to rotate toward the slag pot 100. After reaching a certain position, the locking hook 230 completely disengages from the fixed column due to gravity and rotates to the bottom of the rod seat 220. When the mouth of the slag pot 100 is already in a horizontal orientation, the lifting rod 200 can be continuously lifted, and the rotating rod 300 follows the movement, and finally the mouth of the slag pot 100 is vertically downward. In other words, the tilting mechanism of the slag pot 100 realizes the automatic unlocking of the locking mechanism between the lifting rod 200 and the slag pot 100 during this process, and the locking mechanism has a simple structure and effectively avoids damage to the operator during manual operation.

[0026] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
