Description

Technical Field

[0001] The present application relates to the technical field of clamps, and in particular to a clamp for fixing and repairing a converter air bag. Background Art

[0002] The converter is a rotating cylindrical steelmaking blast furnace, which can be used for blowing steel or blowing matte. The converter body is made of steel plates, cylindrical, lined with refractory materials, and heated by chemical reaction heat during blowing, without external heat source. It is the most important steelmaking equipment and can also be used for copper and nickel smelting. Converter steelmaking is mainly a steelmaking method using liquid pig iron as raw material. Its main characteristics are: relying on the physical heat of liquid pig iron in the converter and the heat generated by the chemical reaction of various components in the pig iron (such as carbon, manganese, silicon, phosphorus, etc.) with the oxygen fed into the furnace, the metal reaches the composition and temperature required for steelmaking. The charge is mainly molten iron and slag (such as lime, quartz, fluorite, etc.). To adjust the temperature, scrap steel and a small amount of cold pig iron and ore can be added. In the converter steelmaking process, the carbon in the molten iron reacts with the blown oxygen at high temperature to generate a mixed gas of carbon monoxide and a small amount of carbon dioxide, namely converter gas.

[0003] The converter gas is usually discharged from the furnace through the converter wind bag. Since the gas is corrosive to a certain extent, it will cause corrosion damage to the wind bag, so the wind bag needs to be disassembled and repaired regularly.

[0004] During the maintenance process, a bench vise is usually used to apply force to both sides of the converter air bag to clamp and fix its position, so that maintenance personnel can easily check its internal conditions. However, due to the irregular shape of the converter air bag, it is difficult for traditional bench vises to fix the position of the air bag, causing the air bag to move up and down, resulting in unstable clamping.

[0032] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0033] Embodiment 1:

[0034] See also Figure 1 , Figure 2 and Figure 3 A fixture for fixing and repairing a converter air bag comprises a vertical plate 1, and the fixture for fixing and repairing a converter air bag further comprises:

[0035] A first clamping plate 2 is arranged at the bottom of the vertical plate 1, a second clamping plate 3 is arranged above the first clamping plate 2, and an adjusting bolt 4 is detachably connected to the first clamping plate 2;

[0036] The first clamping plate 2 , the second clamping plate 3 and the vertical plate 1 form a clamping space.

[0037] Specifically, the vertical plate 1, the first clamping plate 2, and the second clamping plate 3 are all made of steel. The first clamping plate 2 and the vertical plate 1 are fixed by welding, and can also be formed by bending a whole steel plate; the second clamping plate 3 and the vertical plate 1 are fixed by welding; the distance between the first clamping plate 2 and the second clamping plate 3 should be greater than the height of the converter air bag. In other words, the clamping space formed by the first clamping plate 2, the second clamping plate 3 and the vertical plate 1 can allow the converter air bag to move in and out freely from the side; according to the distance between the first clamping plate 2 and the second clamping plate 3, a suitable adjusting bolt 4 is selected. When the converter air bag is fixed, the lower end of the screw of the adjusting bolt 4 needs to be able to abut against the upper surface of the converter air bag;

[0038] The working process is as follows: place the converter wind bag flat on the first clamping plate 2, turn the adjusting bolt 4 to make its screw move downward and gradually approach the converter wind bag until it abuts against the converter wind bag, and manually apply force to the wind bag to detect whether the wind bag is clamped stably. If it is not stable, continue to turn the adjusting bolt 4 to increase the squeezing force of the adjusting bolt 4 on the converter wind bag until the wind bag is completely fixed. At this time, the inspection personnel begin to inspect and repair the inside of the wind bag. After the inspection or maintenance is completed, turn the adjusting bolt 4 in the opposite direction to make its screw move upward and gradually move away from the converter wind bag. When the squeezing force applied by the adjusting bolt 4 to the converter wind bag disappears, the wind bag can be removed.

[0039] In the present embodiment, a first clamping plate 2 and a second clamping plate 3 are provided to form a clamping space with the vertical plate 1 to facilitate the placement of the converter air bag, and an adjusting bolt 4 is provided to abut against the upper surface of the converter air bag so that the converter air bag is fixed due to the extrusion force. Since the extrusion force comes from the vertical direction, the freedom of the converter air bag in the vertical direction is restricted, thereby avoiding the up and down movement of the air bag, and by rotating the adjusting bolt 4, the extrusion force can be increased, further enhancing the stability of the clamping, thereby avoiding the problem of unstable clamping.

[0040] Embodiment 2:

[0041] See also Figures 1 to 3 Based on the first embodiment, further and optionally, a slide plate 5 is fixedly connected to the bottom of the first clamping plate 2 .

[0042] Specifically, the slide plate 5 and the first clamp plate 2 can be fixed by welding or by bolts; such an arrangement enables the slide plate 5 to drive the vertical plate 1, the first clamp plate 2, the second clamp plate 3 and the adjusting bolt 4 to move synchronously when it moves, so as to facilitate the movement of the clamp.

[0043] Further and optionally, slide grooves 6 are provided on both sides of the slide plate 5;

[0044] The slide groove 6 is fixed on the ground or the operating table, and the opening of the slide groove 6 faces the slide plate 5 .

[0045] Both ends of the slide plate 5 extend into the slide groove 6 through the opening and are slidably connected with the slide groove 6 .

[0046] Specifically, in order to facilitate the inspection of the wind bag, the slide 6 can be fixed on an operating table at a certain height from the ground, and the slide plate 5 can slide into or out of the slide 6 from the opening side of the slide 6; in this way, when the clamp is old or damaged, the old or damaged clamp can be removed by sliding out of the slide 6, and then the new clamp can be installed by sliding it into the slide 6.

[0047] Further and optionally, a first reinforcing rib 7 is provided between the vertical plate 1 and the sliding plate 5 .

[0048] The addition of the first reinforcing rib 7 can increase the structural strength and stability between the vertical plate 1 and the sliding plate 5 and improve the service life of the clamp.

[0049] Further and optionally, a second reinforcing rib 8 is provided between the vertical plate 1 and the second clamping plate 3 .

[0050] The second reinforcing rib 8 is added to increase the structural strength and stability between the vertical plate 1 and the second clamping plate 3 , thereby increasing the service life of the clamp.

[0051] Further and optionally, the adjusting bolt 4 includes at least one.

[0052] A plurality of adjusting bolts 4 can be provided to increase the amount of squeezing force, thereby further enhancing the stability of clamping.

[0053] Further and optionally, the surface of the clamp is subjected to rust-proof treatment.

[0054] The anti-rust treatment can be: paint is applied on the surface of the fixture to form a protective film to effectively isolate air and moisture to achieve the purpose of rust prevention; anti-rust oil can be applied on the surface of the fixture to form a dense protective film to prevent oxidation; a layer of corrosion-resistant metal, such as zinc, chromium, etc., can be plated on the surface of the fixture through electroplating technology to improve the corrosion resistance of the metal; a stable oxide film or sulfide film can be formed on the surface of the fixture through chemical reaction to play a rust-proof role; the fixture material can also be heated to a certain temperature and then quickly cooled to form a dense oxide film on its surface to play a rust-proof role; and a vapor phase corrosion inhibitor protective film can be formed on the surface of the fixture to inhibit the corrosion reaction on the fixture surface.

[0055] In this embodiment, by performing rust-proof treatment on the surface of the clamp, the performance of the clamp is guaranteed and the service life of the clamp is increased.

[0056] The working process of the present application is as follows: slide the clamp into the slide groove 6 from the open side of the slide groove 6 to install the clamp. After the clamp is installed, place the converter air bag flat on the first clamp plate 2, turn the adjusting bolt 4 to fix the converter air bag, and after the inspection or maintenance of the air bag is completed, turn the adjusting bolt 4 in the opposite direction to remove the converter air bag.

[0057] In summary, the present application sets the first clamping plate 2 and the second clamping plate 3 to form a clamping space with the vertical plate 1 for placing the converter air bag, and sets the adjusting bolt 4 to abut the upper surface of the converter air bag so that it is fixed due to the extrusion force. Since the extrusion force comes from the vertical direction, the freedom of the converter air bag in the vertical direction is limited, thereby avoiding the up and down movement of the air bag, and by rotating the adjusting bolt 4, the extrusion force can be increased, and the stability of the clamping can be further enhanced, thereby avoiding the problem of unstable clamping. When the clamp of the present application is old or damaged, the old or damaged clamp can be removed by sliding out the slide groove 6, and then the new clamp can be installed by sliding the new clamp into the slide groove 6. The present application increases the structural strength and stability between the vertical plate 1 and the slide plate 5 and the second clamp 3 by adding the first reinforcing rib 7 and the second reinforcing rib 8, thereby improving the service life of the clamp. The present application ensures the performance of the clamp and improves the service life of the clamp by performing rust-proof treatment on the surface of the clamp.

[0058] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
