Description

Technical Field

[0001] The utility model belongs to the technical field of sintering machines, and in particular relates to an auxiliary device for installation and disassembly based on a sintering machine trolley. Background Art

[0002] Sintering is an important production process for sintered ore required for blast furnace ironmaking. The sintering machine is an annular rotary device composed of a trolley, bellows, tracks, head and tail transmission star wheels, etc., with supporting distribution, ignition, exhaust, and sintered ore crushing systems to complete the entire sintering process.

[0003] The head and tail transmission star wheels in the sintering machine are divided into active star wheels and driven star wheels. The track consists of an upper track and a lower track, and the two ends are respectively connected to the apex and bottom points of the active star wheel and the driven star wheel. The rotation track of the upper track, active star wheel, lower track and driven star wheel is full of trolley bodies, and two adjacent trolley bodies fit together. In normal use, the upper track, lower track and driven star wheel are not driven, and the trolley body is driven by the active star wheel and the thrust provided by the active star wheel realizes the transmission of all trolley bodies along the rotation track.

[0004] After the sintering machine trolley body and tracks have been used for a certain number of years, a large number of trolleys need to be taken offline for repair and track replacement. However, when the trolley is reinstalled, the trolley will fall rapidly due to its own gravity when entering the star wheel, causing the trolley and the star wheel to be subjected to severe impact loads, causing great damage to the equipment and the risk of trolley derailment. The assembling and disassembling is difficult and the stability is insufficient, which is not conducive to the operation of the staff and affects the disassembling and assembly efficiency.
