Metallurgical bridge crane

Abstract

The invention discloses a metallurgical bridge crane. The metallurgical bridge crane comprises a cross beam, movable pulley blocks, lifting forks, lifting hooks and a plurality of pin shafts used for hinging two parts. The two parts comprise the first part and the second part which is at least partially located inside the first part so as to be hinged to the first part through the pin shafts. The two ends of each pin shaft extend out of the first part. Grooves are formed in the positions, close to the two ends, of each pin shaft. Baffles used for preventing the pin shafts from being disengaged from the two parts are inserted in the grooves, and the baffles are fixed to the first part. Indicating rods are fixedly arranged at the ends of the pin shafts. By the adoption of the metallurgical bridge crane, the parts can be prevented from being disengaged, and safety accidents are avoided.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular, the invention relates to a metallurgical bridge crane. Background technique [0002] Metallurgical bridge cranes are mainly responsible for the hoisting, feeding, and casting of ladles or ladles in the steelmaking process. The working environment is extremely harsh, with high temperature and dust. As mentioned above, metallurgical bridge cranes are exposed to open flames and subjected to impact loads for a long time during work, which is prone to failure. At the same time, due to the presence of dust in the working environment, it is difficult to find faults even if they exist. [0003] Such as figure 1 , figure 2 As shown, in the prior art, the metallurgical bridge crane includes a beam 1, a movable pulley block 2, a suspension fork 3, a hook 4 and a pin shaft 6, and the number of pin shafts 6 is multiple, such as the first pin mentioned below The shaft 601 , the second ...

AI Technical Summary

Problems solved by technology

Since there is a certain distance between the pin shaft and the ground, it is not easy to observe even if the pin shaft rotates

And once the pin shaft slips out from the assembly hole, the ladle or ladle will fall off, resulting in a safety accident

[0006] (2) Beams and suspension forks are usually manufactured by welding steel plates. Long-term exposure to high-temperature baking and impact loads will cause fatigue damage to the steel plates. For example, cracks will occur on the lower side of the beams, which will also cause the ladle or ladle to fall off.
