Problems solved by technology
[0003] Its disadvantages are: the furnace must be shut down when the oxygen lance elevating trolley is replaced offline, the workload of the roller or steel rope replacement is heavy, and the furnace shutdown time is long. After the oxygen lance is reinstalled, the verticality between the oxygen lance and the nitrogen seal of the converter needs to be readjusted, so that the dynamic cost of production and maintenance is high, and the operation is unsafe

Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0013] like figure 1 , figure 2 As shown, the moving track 1 is installed on the traversing trolley, the lower end of the maintenance track 3 is fixed to the supporting steel platform D, the rails on both sides of the maintenance track 3 are not equal in height, and the upper end of the high side track of the maintenance track 3 is connected to the moving track 1 and the maintenance The steel platform B1 between the tracks 3 is fixed. The upper end of the low side track of the maintenance track 3 is provided with a transition track 2, and the transition track 2 is fixed to the steel platform B2 between the moving track 1 and the maintenance track 3. There is a certain small gap between the upper end of the transition track 2 and the moving track 1, usually 5mm-10mm. There is a second gap Y2 between the lower end of the transition track 2 and the ...

The invention discloses an overhaul track of an oxygen lance lifting bogie, which comprises a movable track (1) arranged on a traversing trolley and an overhaul track (3) the lower end of which is fixed with a supporting steel platform (D) and the upper end of which is fixed with a first steel platform (B1), the tracks on the two sides of the overhaul track (3) are unequal in height, a first gap (Y1) for taking out the roller of the oxygen lance lifting bogie is arranged between the high-side track of the overhaul track (3) and the movable track (1), the upper part of the low-side track of the overhaul track (3) is provided with a transitional track (2) fixed with a second steel platform (B2), and a second gap (Y2) for taking out the roller of the oxygen lance lifting bogie is arranged between the transitional track (2) and the overhaul track (3), and the first gap (Y1) and the second gap (Y2) are arranged alternately. The invention can use the gaps staggered in height on the two sides of the overhaul track to carry out on-line lance hanging maintenance and replacement on the roller of the oxygen lance lifting bogie or the steel rope under the condition that the furnace is not stopped.
Description
technical field [0001] The invention belongs to the technical field of metallurgical equipment, and relates to an inspection track for an oxygen lance lifting trolley. Background technique [0002] At present, there is no online maintenance and replacement device for the rollers or steel ropes of the rail-wrapped oxygen lance lifting trolley in the domestic steelmaking workshop. The oxygen and water cooling pipes of the lance are separated from the connecting flange of the lifting trolley, and the oxygen lance is hoisted away from other places, and then the oxygen lance lifting trolley is disengaged from the steel rope, and the oxygen lance lifting trolley is hoisted from the moving track to the inspection position, and then carried out Oxygen lance lifting trolley rollers or steel ropes are replaced off-line. After the replacement is completed, the lifting trolley and oxygen and water pipes are finally reassembled. [0003] Its disadvantages are: the furnace must be shut d...
