Description
Technical Field
The invention relates to a coke oven machine and a coke side operating table structure, in particular to a sliding operating table in a coke oven.
Background
The machine and the coke side operation table of the large-volume coke oven generally adopt reinforced concrete structures at end tables, intermediate tables and coal tower sections of the coke oven, and beam columns of the coke oven sections adopt metal structures. The table top of the machine side operation table can adopt precast reinforced concrete plates, and the coke side operation table generates vibration due to the periodical operation of the coke guide, so that the table top is often cast in situ by adopting reinforced concrete plates. And (3) paving an iron plate on the top surface of a machine coke side operation table of the coke oven body section, wherein the elevation of the iron plate is suitable for replacing a oven door frame in production.
The side operating table and the coke side operating table of the coke oven generally adopt one of the following three types: external sliding type, internal sliding type and cantilever type. Since the lateral expansion of the oven brickwork has a certain effect on the machine and the coke side operating table, an expansion gap must be provided between the top end of the operating table support column and the operating table cross beam. If the width of the expansion joint does not fully consider the transverse expansion of the furnace body, the expansion stress is slow and directly acted on the operation table, and finally the operation table is overturned.
For the inner sliding type operation table, in order to adapt to the transverse expansion of the coke oven body, sliding measures are firstly adopted at the lower end of a beam at the inner side of the operation table, namely two round steels are placed on bracket of a furnace column, and calcium-based lubricating grease (yellow grease) is smeared to reduce friction resistance. This solution has two significant drawbacks: firstly, gaps between the operation table cross beam and the furnace column bracket can accumulate dust, coke particles and tar in the production process, and the gaps are mixed with lubricating grease smeared on the gaps to form hard dirt which is difficult to clean, so that round steel mounted on the gaps is prevented from sliding. Secondly, the size of the gap between the operation table beam and the furnace column bracket is generally 50-100mm according to the furnace type, and the size of the gap gradually increases in the whole life of the coke furnace. After the coke oven is transferred into normal production, the gap between the cross beam of the operation table and the bracket of the furnace column gradually becomes larger due to the expansion of the coke oven masonry in the vertical direction, so that the diameter of round steel arranged at the position needs to be frequently adjusted, and the time and the labor are wasted and the cost is high.
