Background
The coking industry mainly comprises the process of charging coal into a coking chamber for high-temperature dry distillation to form coke, and related coking vehicles mainly comprise a coal charging vehicle, a coke pushing vehicle, a coke barrier vehicle and a coke quenching vehicle. The coke pusher has the function of completing the functions of taking and closing the oven door and pushing coke on the side of the coke chamber of the coke oven, and the coke pushing process of the coke pusher utilizes the driving gear and the rack of the coke pushing rod body to drive the coke pushing rod to move back and forth, so that the coke pushing rod enters the coke chamber to push the mature coke out of the coke chamber. Therefore, the coke pushing rod is a key part of the coke pushing trolley and has high value, but the coke pushing rod is easy to bow and bend.
The coke pushing rod enters the coking chamber with the temperature of over 1000 ℃ for a long time, and is easy to deform gradually under the resistance of coke. When the pushing ram does not work, the pushing ram retracts to the supporting wheel to be placed, and the upper part of the pushing ram is easy to bow due to the fact that the pushing ram is heavy and the lower part of the pushing ram is not supported. When the coke pushing rod does not work, the coke pushing rod is retracted to the supporting wheel for placing, and the rod body is easy to bend gradually because the hot coke pushing rod is influenced by the environment (if one side is often blown).
In summary, how to solve the problem that the coke pushing rod is easy to bend is a problem to be solved urgently by those skilled in the art.
