The gantry can drag the furnace covers 1 of multiple pit furnaces to open and close. The water, gas, electricity and other connecting pipelines 2 of each pit furnace are connected to the furnace cover 1 of each pit furnace through the drag chain 3 from the pit. During the opening and translation process of the furnace cover 1, a long hole 4 of the pit cover needs to be opened at the place where the drag chain 3 passes, and a fence 5 is placed around the long hole 4 of the pit cover. Therefore, there are some problems in actual work. A. Affected by the height of the drag chain and the furnace cover, the fence cannot meet the height requirements specified in the national standard; B.
