AI Technical Summary
The existing method of fixing the lining bricks of coke oven doors cannot guarantee the coaxiality of the bolts and the fixing steel plate, resulting in inaccurate alignment between the anchor bolts and the holes in the oven door frame, which affects the fixing strength and service life of the lining bricks.
The threaded sleeve of the connecting positioning component is coaxially slidably engaged with the mating hole, and the top surface of the fixed base plate is contacted by the limiting flange to ensure the verticality of the anchor bolt. At the same time, the bottom forked part of the anchor bolt is pre-embedded in the refractory lining brick to enhance the pre-embedding stability.
Ensuring accurate alignment between the anchor bolts and the holes in the furnace door frame improves the fixing strength and service life of the lining bricks, and enhances the support and connection stability of the refractory lining bricks.

TECHNICAL FIELD
[0001] The utility model relates to the field of coke oven door lining brick installation auxiliary assembly, concretely relates to a connecting structure for coke oven door lining brick fixing bolt. BACKGROUND
[0002] The coke oven is a basic furnace for coking, which provides important coke and coal gas for the metallurgical industry, and the working temperature is 900-1100 degrees Celsius. The coke oven door refers to the coke oven auxiliary equipment that opens and closes the coke oven carbonization chamber at both ends of the oven mouth. When the door is closed, the carbonization chamber is isolated from the atmosphere, and when it is opened, the coke pushing rod can push out the coke. In order to protect the door and reduce the heat loss of the carbonization chamber, refractory lining bricks are often built on the side of the coke oven door facing the carbonization chamber or the lining bricks are directly inlaid on the door frame.
[0003] Specifically, in the operation of inlaying refractory lining bricks on the door frame, a through hole corresponding to the mounting hole position on the door frame is usually reserved on the refractory lining brick, and then the refractory lining brick is fixed on the door frame by inserting and adding bolts. However, this setting method of directly fixing the refractory lining brick on the door frame by bolts cannot effectively support the lining brick for a long time due to the limited fixing strength, and cannot withstand the frequent opening and closing of the door for a long time, thereby affecting the service life.
[0004] A Chinese patent with application number 202121505585.4 discloses a fixing piece for coke oven door lining brick and a door lining brick with the fixing piece. The specific scheme includes: the fixing piece includes a fixed steel plate matched with the lining brick body and a first Y-shaped anchor bolt. The inner side of the fixed steel plate faces the lining brick body, and the other side is the outer side. The first steel plate is symmetrically provided with first bolt holes in two columns from left to right. The first Y-shaped anchor bolt includes a first main shaft and two first bifurcated arms integrally formed. The first main shaft is provided with a first fixed nut and a movable nut. The first main shaft is arranged in the first bolt hole. The first fixed nut is located on the inner side of the fixed steel plate and connected with the fixed steel plate. The movable nut is located on the outer side of the fixed steel plate and threadedly connected with the first main shaft. Although the above-mentioned scheme enhances the support effect of the door lining brick by setting the fixing piece anchor, when the anchor bolt is inserted into the fixed steel plate, the fixed nut used to limit and constrain the anchor bolt is fixed on the bottom surface of the fixed steel plate by welding and positioned and contrasted with the bolt hole of the fixed steel plate. This causes the coaxiality of the fixed nut and the bolt hole to be unable to be guaranteed, which leads to the anchor bolt being easily not perpendicular to the top surface of the fixed steel plate when the anchor bolt is inserted, and directly causes the refractory lining brick to be unable to be fixed on the door frame.
