Description

Technical Field

[0001] This utility model relates to the technical field of furnace front opening machine devices, and in particular to an opening machine track cleaning device. Background Technology

[0002] The taphole opening machine is a key piece of equipment for blast furnace tapping. Its core function is to safely and efficiently open the taphole that is blocked by special castable material during blast furnace tapping. It penetrates the hard blockage through a combination of drilling and impact, forming a channel for molten iron to flow out, thereby guiding the molten iron and slag in the furnace to flow out smoothly.

[0003] The straight and unobstructed track of the taphole opening machine ensures that the machine can quickly align with the taphole, thus smoothly completing the drilling and taphole opening operation. This not only directly improves the efficiency and stability of tapping but also effectively avoids delays or safety accidents caused by equipment positioning deviations, ensuring the continuous and smooth operation of blast furnace production.

[0004] However, in the actual working environment of the taphole machine, some molten iron and slag will splash onto the taphole machine trolley track when the taphole is about to open and during tapping. This is a very troublesome problem in the tapping operation. The high-temperature molten iron and slag will solidify rapidly upon contact with the track, forming hard slag nodules. These slag nodules will seriously hinder the smooth movement of the taphole machine trolley on the track. When the track is obstructed, the taphole machine cannot quickly and accurately align with the center of the taphole, making subsequent drilling and tapping operations extremely difficult, or even forcing them to be interrupted. Even worse, if the taphole machine trolley track is obstructed during tapping operations, the trolley will not be able to retreat smoothly to place the taphole machine at the taphole, which will be exposed to high temperatures and damage the taphole machine equipment. Prolonged inability to open the taphole will cause internal pressure buildup in the blast furnace, preventing the blast furnace from operating smoothly, and may even reduce blast, thus reducing tapping efficiency. Therefore, cleaning the slag nodules formed by molten iron splashed onto the taphole machine track is also a key step in ensuring smooth tapping. Utility Model Content

[0005] The purpose of this invention is to provide a track cleaning device for an opening machine, which can clean up iron slag that splashes onto the track of the opening machine, ensuring the smooth operation and retraction of the opening machine trolley, and improving the smoothness and stability of iron tapping.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A track cleaning device for an opening machine includes a moving track and an opening machine trolley that travels along the moving track. Moving grooves are opened on both sides of the moving track. The opening machine trolley includes side fixing plates on both sides. Moving wheels and cleaning components are connected to the inner side of the side fixing plates. The moving wheels abut against the bottom surface of the moving grooves. The cleaning components include a vertically penetrating fixing groove and several steel cables in the fixing groove. The lower ends of the steel cables abut against the bottom surface of the moving grooves.

[0007] By adopting the above technical solution, the movable troughs opened on both sides of the moving track can reduce the splashing of molten iron into the trough. The steel cable is made of multiple strands of steel wire wrapped around the steel wire rope core and twisted into a spiral shape multiple times. The multiple steel cables are attached to the bottom of the movable trough. As the opening machine trolley moves, the movable trough is cleaned, which improves the cleanliness of the movable trough, ensures that the opening machine trolley can operate and return smoothly, and improves the smoothness and stability of iron tapping.

[0008] Furthermore, the diameter of the steel cable is in the range of 16-20mm.

[0009] By adopting the above technical solution, the setting of the steel cable diameter ensures that it has a certain rigidity and internal steel wire count, thereby improving the cleaning effect.

[0010] Furthermore, the height of the steel cable is in the range of 100-130mm.

[0011] By adopting the above technical solution, the diameter of the steel cable ensures that it has a certain self-weight and length, giving it a certain flexibility or room for vertical movement, thus avoiding stubborn iron slag nodules from directly damaging or fixing the steel cable.

[0012] Furthermore, the side fixing plate is also connected to a spacer baffle, which is positioned between the steel cable and the moving wheel.

[0013] By adopting the above technical solution, a spacer baffle is placed between the steel cable and the moving wheel to reduce interference between the two.

[0014] Furthermore, the gap between the lower end of the spacer baffle and the bottom surface of the moving trough is smaller than the diameter of the steel cable.

[0015] By adopting the above technical solution, damage to the wheels of the opening machine trolley is prevented from being caused by iron slag. In extreme cases, damage to the steel cable or fixed slot can affect the movement of the moving wheels. This protects the track of the opening machine trolley, reduces damage to the wheels of the opening machine trolley, and lowers the replacement frequency and maintenance costs of the wheels of the opening machine trolley.

[0016] Furthermore, the spacer baffle has positioning holes, and a matching positioning block is connected to the side of the fixing slot near the spacer baffle.

[0017] By adopting the above technical solution, the installation position of the fixed card slot can be easily positioned by the spacer baffle, thus achieving pre-positioning and facilitating the subsequent installation and fixing of the fixed card slot.

[0018] Furthermore, the steel cables are arranged side by side and distributed along the width direction of the bottom surface of the moving trough.

[0019] By adopting the above technical solution, the bottom surface of the moving trough can be thoroughly cleaned, thus improving the cleaning effect.

[0020] Furthermore, the through hole in the fixed slot is inclined, with the inner end tilted towards the front, so that the internal steel cable is arranged in front of the external steel cable.

[0021] By adopting the above technical solution, it is easier to sweep the residue to the outside, thereby improving the cleaning effect of the moving trough; and the inclined fixed slot allows for the installation of more steel cables, and adjacent steel cables can partially overlap in the width direction, thus improving the final cleaning effect.

[0022] Furthermore, the fixing slot is U-shaped, and the steel cable is inserted or removed from the opening end of the fixing slot, which is connected to the side fixing plate.

[0023] By adopting the above technical solution, it is convenient to put the steel cable into or take it out from the opening end of the fixed slot, making it easier to replace the steel cable in the fixed slot and improving convenience.

[0024] In summary, this utility model has the following beneficial effects: The movable troughs on both sides of the moving track reduce molten iron splashing into the troughs. The cleaning component uses a fixed slot running vertically through the track and several steel cables within the slot. The steel cables work together with multiple strands of steel wire to clean the troughs. As the tapping machine trolley moves, it cleans the troughs, improving their cleanliness. This ensures the tapping machine trolley track remains smooth and unobstructed, allowing for smooth operation and retraction, thus improving the smoothness and stability of tapping. It also increases the success rate of tapping, avoids interruptions in tapping caused by blockages in the tapping machine trolley track, ensures continuous and stable blast furnace tapping, and helps save labor time and maintenance costs.

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0028] A track cleaning device for an opening machine, such as Figure 1 As shown, it includes a moving track 1 and an opening machine trolley 2. The opening machine trolley 2 travels along the moving track 1 to perform operations or return. The opening machine trolley 2 penetrates hard blockages by combining drilling and impact to form a channel for molten iron to flow out, thereby guiding the molten iron and slag in the furnace to flow out smoothly.

[0029] like Figure 1 and Figure 2 As shown, the moving track 1 has moving grooves 11 on both sides. The opening machine trolley 2 includes side fixing plates 21 on both sides. The moving wheels 22 and the cleaning components are connected to the inner side of the side fixing plates 21. The moving wheels 22 abut against the bottom surface of the moving groove 11. The cleaning components include a vertically penetrating fixing groove 3 and three or more steel cables 31 in the fixing groove 3. The lower end of the steel cables 31 abuts against the bottom surface of the moving groove 11. As the steel cables 31 contact the moving groove 11, they clean the iron slag. Through friction treatment, the iron slag on the opening machine trolley track is shortened or falls down, and it always maintains contact with the moving track 1 to carry out cleaning work for a long time. In this embodiment, the diameter of the steel cable 31 is in the range of 16-20mm, and the height is in the range of 100-130mm; the side fixing plate 21 is also connected to a spacer baffle 23, which is positioned between the steel cable 31 and the moving wheel 22, and there is a gap between the lower end of the spacer baffle 23 and the bottom surface of the moving groove 11. This gap is smaller than the diameter of the steel cable 31, and in this embodiment, it is smaller than the radius of the steel cable 31.

[0030] like Figure 1 As shown, steel cables 31 are arranged side by side and distributed along the width of the bottom surface of the moving groove 11. The steel cables 31 can be fixed in the fixing groove 3 by means of glue or screws, or they can be pressed downwards by their own weight and jump upwards when they encounter steel slag that cannot be removed (the fixed steel cables can also make some room due to their own flexibility), thereby improving the service life of the steel cables. In some embodiments, the through holes in the fixing groove 3 are inclined, with the inclination direction being that the inner end is inclined to the front side, so that the inner steel cables 31 are arranged in front of the outer steel cables 31, and the two sets of steel cables 31 on the left and right are distributed in a figure-eight shape, which facilitates the removal of iron slag nodules outwards. In this embodiment, the spacer baffle 23 has a positioning hole, and the fixing slot 3 is connected to a matching positioning block on the side near the spacer baffle 23 to insert into the spacer baffle 23 for positioning, which facilitates installation and fixing. The fixing slot 3 is U-shaped, and the steel cable 31 is inserted or removed from the opening end of the fixing slot 3. The opening end of the fixing slot 3 is connected to the side fixing plate 21 by two sets of screws. After the fixing slot 3 is pre-positioned and abutted against the spacer baffle 23 by the positioning block, the screw passes through the side fixing plate 21 and is threaded to the fixing slot 3 to achieve fixing.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
