Description
Technical Field
The utility model relates to an operation panel structure of coke oven machine, burnt side especially relates to a slip operation panel in coke oven.
Background
The machine and coke side operation platform of the large-capacity coke oven generally adopts reinforced concrete structures in the coke oven end platform, the middle platform and the coal tower section, and adopts a metal structure in the beam column of the coke oven section. The table top of the machine side operating table can adopt a prefabricated reinforced concrete plate, and the coke side operating table generates vibration due to the periodic operation of the coke guide, so the table top is usually cast with the reinforced concrete plate on site. The top surface of the machine coke side operation table of the coke oven body section is paved with a cast iron plate, and the elevation of the cast iron plate is preferably not influenced by the replacement of the oven door frame in production.
The machine side console and the coke side console of a coke oven typically take one of three types: an outer slide type, an inner slide type, and a cantilever type. Because the transverse expansion of the coke oven masonry has certain influence on the machine and the coke side operating platform, an expansion joint must be arranged between the top end of the operating platform support and the operating platform beam. If the expansion gap width does not fully consider the transverse expansion of the furnace body, the expansion stress is slowly and directly acted on the operation platform, and finally the operation platform is overturned.
For the internal sliding type operating platform, in order to adapt to the transverse expansion of the coke oven body, firstly, a sliding measure is adopted at the lower end of a cross beam on the inner side of the operating platform, namely two round bars are placed on the bracket of the oven column, and calcium-based lubricating grease (yellow dry oil) is coated to reduce the friction resistance. This solution has two significant drawbacks: firstly, the gap between the cross beam of the operating table and the bracket of the oven column can accumulate dust, coke particles and tar in the production process, and the dust, the coke particles and the tar are mixed with lubricating grease coated on the gap to form hardened dirt which is difficult to clean, so that the sliding of round steel arranged on the gap is prevented. Secondly, the gap between the cross beam of the operating platform and the bracket of the oven column is usually between 50 and 100mm according to different oven types, and the size is gradually increased in the whole service life of the coke oven. After the coke oven finishes baking and is shifted to normal production, because the expansion of the coke oven masonry in the vertical direction, the gap between the cross beam of the operating platform and the bracket of the oven column can be gradually enlarged, so that the diameter of the round steel arranged at the position needs to be adjusted frequently, and the method is time-consuming, labor-consuming and high in cost.
