[0022] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0023] Example 1

[0024] The utility model provides an auxiliary tool for adjusting the positioning of coke oven casings. According to the length of each row of coke oven casings, each row of coke oven casings is provided with a plurality of casings arranged adjacent to each other at a specified interval, including a long angle steel and a long square tube.

[0025] Please refer to Figure 1 , Figure 1This is a schematic diagram of the positioning aid structure of an embodiment of the present invention. As shown, the long angle steel strip is a straight angle steel 1, and the long square tube is a straight square tube 2. The long angle steel strip is arranged parallel to the long square tube, and several connecting rods are disposed between the long angle steel strip and the long square tube. One end of the connecting rod is welded to the angle steel strip, and the other end is welded to the square tube. The length of the connecting rod is equal to the diameter of the sleeve. The number of connecting rods matches the number of sleeves, so that the angle steel and square tube are perpendicular to the connecting rods. During use, the sleeve is clamped in a bracket composed of the angle steel, connecting rod, and square tube, which includes a cleaning pipe 4 and a lower nozzle 5. The length of the long angle steel strip is greater than the length of each row of coke oven sleeves. The length of the long square tube is greater than the length of each row of coke oven sleeves. The connecting rod is made of square tube. The bracket is equipped with diagonal braces 6 to increase its strength.

[0026] Example 2

[0027] Method of using the positioning auxiliary tool for adjusting the coke oven casing of the utility model:

[0028] 1. At both ends of the X-axis of the coke oven, mark the position of the casing according to the drawing, and then weld straight angle steel according to the mark, with one angle steel welded for each row of casing.

[0029] 2. Use a straight square tube to weld an auxiliary tool for each of the two casings according to the distance between the two casings in the X-axis direction of the coke oven and the diameter of the casing (a total of two casings, each with a smooth and long auxiliary tool).

[0030] 3. Find the center line of the auxiliary tool and mark it.

[0031] 4. Align the centerline of the auxiliary tool with the centerline 3 of the coke oven. The square tube welded to the auxiliary tool according to the casing diameter forms a 90-degree angle with the angle steel. Then, secure the casing with the fixing fixture. After adjusting one row of casing, remove the positioning auxiliary tool and secure the next row of casing, and reuse it.

[0032] The utility model has substantial characteristics and significant technical progress. Compared with the original installation method, the positioning auxiliary tool for adjusting the coke oven casing of the utility model only requires welding two full-length auxiliary tools according to the setting requirements of the coke oven casing. The auxiliary tool is made of square tubes, is not easy to deform, and can be reused, which saves time and difficulty. It saves time and manpower, and greatly improves the accuracy of casing installation.

[0033] The above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Persons skilled in the art may make various modifications or variations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of the present invention and are defined by the claims.
