Anti-blocking device for KR process stirring desulfurization lifting trolley

Abstract

The invention relates to an anti-blocking device for a KR process stirring desulfurization lifting trolley. The anti-blocking device comprises a fixed bracket, a movable bracket, transmission wheels,bearings with vertical seats, supporting seats and adjusting bolts. The transmission wheels are suspended in the fixed bracket through the movable bracket, the two ends of each supporting seat are supported by the bearings with vertical seats, the upper ends of the adjusting bolts pass through the supporting seats and are connected with weighing sensors, and the lower ends of the adjusting bolts are hinged to ear seats on the movable bracket. A steel wire rope drawn out from a steel wire rope reel successively bypasses a first crown block, a second crown block and a movable pulley in a first lifting trolley transmission mechanism, passes through the two transmission wheels, then bypasses a movable pulley, a second crown block and a first crown block in a second lifting trolley transmissionmechanism and then returns to the steel wire rope reel. According to the anti-blocking device, the original two groups of independent transmission systems of the lifting trolley are integrated into an integral transmission system through the transmission wheels, so that the portions, on the two sides of the lifting trolley, of the steel wire rope are ensured to be stressed uniformly, and the blocking of the lifting trolley in a stirring frame is avoided.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to an anti-jamming device for a stirring desulfurization lifting trolley in the KR process. Background technique [0002] In the KR molten iron pretreatment process, the lifting trolley used to drive the stirring desulfurization device is an important operating equipment. The lifting trolley is often driven by a steel wire rope, and whether the transmission steel rope driving the lifting trolley can be evenly stressed and run smoothly will directly affect production. The overall cycle of operation affects the production and operation costs of the entire steel plant. [0003] Such as figure 1 As shown, the conventional lifting trolley transmission system is composed of 2 sets of relatively independent transmission mechanisms, and each set of transmission mechanisms is composed of a lifting motor 2, a wire rope reel 3, a pulley block and a steel wire rope 4, and the w...
