Description
Technical Field
The invention relates to the technical field of metallurgical engineering construction, in particular to a method for correcting deviation of coke pushing equipment on a coke pusher during installation.
Background
The coke pushing equipment mainly refers to various coke pushing devices on a coke pusher. When the coke pushing equipment is installed, due to equipment manufacturing errors and installation errors, the situation that the vertical deviation between the central line of the reserved bolt of the coke pushing equipment and the central line of the track of the coke pusher exceeds an allowable value easily occurs, so that the installation of a door taking mechanism, a furnace door cleaning device, a furnace frame cleaning device, a coke pushing rod and a coal leveling rod is influenced, and the adjustment is needed.
There are generally two methods for adjusting the coke pushing equipment. The first method is to ream the hole on the frame structure, namely under the condition of ensuring the central line of the coke pushing rod to be vertical to the central line of the coke pusher track, ream the hole of the equipment installation bolt hole and then install the equipment installation bolt hole. And the second method is to totally disassemble all steel structures and equipment of the coke pusher, perform secondary installation after checking layer by layer again, and perform reaming if necessary. The second method is suitable for reaming situations where the deviation of the bore beyond the equipment bottom plate inwards is more than 20mm, and can only be installed a second time as this does not allow the cutting equipment to ream. The second method extends the installation period, which causes a significant increase in installation costs and also easily causes damage to the equipment.
