The middle is filled with sealing materials. The outer surface is close to the inner side of the furnace column. It is pressed firmly to the side of the furnace body by the top screw on the furnace column and cannot move freely. The protection plate transmits the spring protection force on the furnace column to the furnace body, protecting the furnace body from cracks when it expands due to heat; the protection plate has high temperature wear resistance and corrosion resistance, and can also extend the life of the masonry; at the same time, it also plays a role in energy saving and high efficiency in coking production.

[0003] In view of the above functions of the protection plate, it will move with the furnace body under the action of expansion force during the coke oven baking process. Because the furnace door frame is installed on the protection plate, and the furnace door is installed on the furnace door frame, the position must be accurate, so the relative displacement between the protection plate and the furnace body is not allowed.

[0004] The existing protection plate limiting technology is to symmetrically set screw top screw components on the outer wing plate of the furnace column to limit the protection plate from the upper end of the protection plate and remove it after the furnace is finished. This component has a thin structure and a single function, and is fixed to the furnace column by welding. The position is also high, and it needs to be removed by hot work, which is inconvenient to construct. Utility Model Content

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-5 As shown, a coke oven protection plate installation and positioning device comprises a first fixing frame and a second fixing frame.

[0023] The first fixing frame includes two brackets 11; the two brackets 11 are symmetrically arranged on both sides of the coke oven column, and the two brackets 11 are fixed to the flange of the protection plate 4 by fasteners; the first extension part 12 is provided on the opposite side of the two brackets 11; the first extension part 12 extends to the interior of the oven column, wherein the coke oven oven column is H-shaped, and the interior of the oven column refers to the space between the two flange plates 31 at the front and rear of the oven column; the two first extension parts 12 are both threadedly connected with a first top screw 13; the first top screw 13 passes through the first extension part 12 and presses on the inner surface of the flange plate 31 of the oven column close to the protection plate 4, and the bracket 11 is kept stable and the protection plate 4 is fixed to the oven column by the support of the first top screw 13, before the protection plate 4 is installed on the furnace head, the first fixing frame first fixes the protection plate 4 firmly on the oven column, and the first fixing frame is removed when the furnace door frame is installed, wherein the first fixing frame is preferably 3 groups, and the protection plate 4 is fixed to the oven column by 3 groups of first fixing frames, and the 3 groups of first fixing frames are all above the second fixing frame;

[0024] The second fixing frame is located below the first fixing frame; the second fixing frame includes two furnace column angle steel supports 21 and two protection plate supports 22, the two furnace column angle steel supports 21 are symmetrically fixed on both sides of the furnace column web 32; the two protection plate supports 22 are symmetrically arranged on both sides of the furnace column web 32, and the two protection plate supports 22 are fixed to the protection plate 4 by fasteners; the two protection plate supports 22 are provided with a second extension portion 23 on the opposite side; the two second extension portions 23 extend horizontally to the opposite side; the two second extension portions 23 are vertically threaded with a second top screw 24; the second top screw 24 passes through the second extension portion 23 and presses on the furnace column angle steel support 21 to install and position the protection plate 4, wherein the furnace column angle steel support 21 is in two installation states, and the inner and outer surfaces of the horizontal limb of the angle steel are used as support surfaces 211 and 212 for supporting the second top screw 24 respectively;

[0025] like Figure 2As shown, a pressure plate 33 is fixed on both sides of the web 32 of the furnace column, wherein the pressure plate 33 corresponds to the position of the large spring of the furnace column, and the pressure plate 33 is parallel to the flange plate 31 of the furnace column; the pressure plate 33 is located above or below the bracket 11, wherein a pressure plate 33 is provided above or below each group of brackets 11; both ends of the two pressure plates 33 extend to the outside of the furnace column; the two pressure plates 33 on the outside of the furnace column are threadedly connected with a third top screw 141; the two third top screws 141 pass through the pressure plate 33 and press on the protective plate 4 , because one side of the two brackets 11 is tightly connected to the edge of the protection plate 4 through fasteners, and the other side is in contact with the furnace column flange plate 31 through the first extension part 12 and the first top screw 13, the protection plate 4 and the furnace column 3 fit naturally. When the third top screw 141 is stretched toward the furnace column flange plate 31 and tightened, additional tension will be added between the furnace column 3 and the protection plate 4, so that the first top screw 13 is pressed tightly against the furnace column flange plate 31. The third top screw 141 is located further outward than the first top screw 13, and the thread is also larger, which is easier to operate when fixing and sliding down the protection plate 4. The first fixing frame and the third top screw 141 are used to fix the protection plate 4 together, which increases the fixing degree of the protection plate 4;

[0026] The third top screw 141 is sleeved with a nut 142; the nut 142 is located on the side of the pressure plate 33 close to the protection plate 4, and the third top screw 141 is locked by the nut 142 to prevent the third top screw 141 from loosening during the installation and movement process.

[0027] As the protective plate 4 moves inwards with the furnace column and approaches the furnace head, the height of the protective plate 4 needs to be adjusted, so that the protective plate 4 needs to be slid downwards to a suitable position. Figure 4 As shown, the second fixing frame is installed so that the second top screw 24 is above the supporting surface 211, the distance that the protective plate 4 needs to be adjusted is calculated and measured, and then the second top screw 24 is rotated so that the distance from the second top screw 24 to the supporting surface 211 is the distance that the protective plate 4 needs to be adjusted; at the same time, the first top screw 13 and the third top screw 141 on both sides of the furnace column are loosened to make the protective plate 4 slowly slide downward along the furnace column, so that the second top screw 24 moves downward with the protective plate 4 until the second top screw 24 presses on the supporting surface 211, and the protective plate 4 is prevented from moving downward through the supporting surface 211, so that the protective plate 4 is adjusted to a suitable position, and the protective plate 4 will not be damaged by collision due to shaking during the installation process, thereby reducing the difficulty of installation;

[0028] After the protection plate 4 is installed against the furnace head, the first fixing frame, the third top screw 141 and the locking nut 142 are removed; the two protection plate supports 22 are removed and the two protection plate supports 22 are turned over and installed, as shown in FIG. Figure 5As shown, the second extension portion 23 is located below the support surface 212. As the coke oven body moves upward under the action of the expansion force during the baking process, the two second top screws 24 are rotated so that the distance between the second top screws 24 and the bottom of the support surface 212 is the distance of the expansion upward movement of the lower section of the furnace body below the top screw of the second top screw 24. After the furnace body expands and moves upward, the second top screw 24 presses against the bottom of the support surface 212 to prevent the protective plate 4 from continuing to move upward under the action of the friction force. After the protective plate support 22 is reversed and the installation direction is flipped, the adjustable section length of the second top screw 24 needs to be greater than the thermal expansion length of the lower section of the furnace body.

[0029] The utility model is installed and used in the following manner: before the furnace column and the protection plate 4 are installed on the furnace head, multiple sets of brackets 11 are installed vertically on the protection plate 4, and the first top screw 13 is pressed against one end of the furnace column close to the protection plate 4 to firmly fix the protection plate 4 on the furnace column, and the third top screw 141 is passed through the pressing plate 33, and the third top screw 141 is tightened;

[0030] When the furnace column and the protection plate 4 are installed close to the furnace head, the two furnace column angle steel supports 21 and the two protection plate supports 22 are respectively installed on both sides of the furnace column web 32 and the protection plates 4 on both sides of the furnace column, so that the second top screw 24 is above the support surface 211, and the distance that the protection plate 4 needs to be adjusted is measured, and then the second top screw 24 is rotated so that the distance from the second top screw 24 to the support surface 211 is the distance that the protection plate 4 needs to be adjusted, and the third top screw 141 is loosened to make the protection plate 4 slowly slide downward along the furnace column, so that the second top screw 24 also moves downward with the protection plate 4 until the second top screw 24 is against the support surface 211, and the positioning of the protection plate 4 is completed;

[0031] After the protection plate 4 is installed against the furnace head, the first fixing frame, the third top screw 141 and the nut 142 are removed; the two protection plate supports 22 are removed and turned over. Figure 5 As shown, the second extension portion 23 is placed below the support surface 212, and then two protection plate supports 22 are installed. The two second top screws 24 are rotated so that the distance between the second top screws 24 and the support surface 212 is the distance that the furnace body moves upward due to expansion. After the furnace is baked, the furnace column angle steel supports 21 and the protection plate supports 22 are removed.
