Online rapid changing method for coke pushing rods of coke pusher

Abstract

The invention discloses an online rapid changing method for coke pushing rods of a coke pusher. The coke pushing rod comprises a coke pushing head, a front coke pushing rod and a rear coke pushing rod, wherein the front coke pushing rod and the rear coke pushing rod are connected through two hinge pins, and a triangular carriage is arranged at the lower ends of the coke pushing rods. The method is characterized by comprising the following steps of: step 1, erecting a first test run platform used for placement of new coke pushing rods, a first rod body shelf, a second test run platform used for placement of disassembled old coke pushing rods and a second rod body shelf on a coke pushing rod repair station; step 2, hanging the new coke pushing rods to the first test run platform and the first rod shelf; and step 4, assembling the new coke pushing rods on the coke pusher. According to the invention, the online rapid changing method for the coke pushing rods of the coke pusher saves the time of disassembling the old coke pushing rods and assembling the new coke pushing rods; and meanwhile, in the process of changing the coke pushing rods, the new and old coke pushing rods are moved through power of the coke pusher itself, and a crane is not needed to match up with the coke pusher essentially, so that the shift cost of the crane is greatly saved.

Description

technical field [0001] The invention relates to an online rapid replacement method for a coke pusher of a coke pusher. Background technique [0002] The coke push rod is mainly used to push the mature coke in the carbonization chamber into the coke quenching car compartment or coke tank, where it is roasted at a high temperature of about 1 000 ℃ in the carbonization chamber, while it is at room temperature outdoors and is repeatedly exposed to high and low temperature environments. , especially once the power is cut off, the coke pushing rod is burned in the furnace for more than 30 minutes, it is very easy to be burned, deformed, bent, and some welds burst. If it is too large, it cannot enter the carbonization chamber, and the coke pusher cannot be used, which will affect production. Since the coke ovens in the Chongqing Iron and Steel New Area were put into production in September 2009, there have been many accidents where the coke pusher rods were burned, and three of th...

Problems solved by technology

[0004] The pin shaft at the connection is a conical tensioning sleeve structure. During use, after repeated thermal expansion, it is very difficult to remove, and the removal time is more than ten hours. In addition, there is a box-shaped connection short inside the connection, which is closely connected with the front and rear sections of the focus pusher. It is not easy to disassemble. The front and rear parts are separated after cutting off the webs on both sides; It is very difficult to move the front focus push lever (about 10t), and it is also very difficult to lift the front focus push lever when reassembling.

From the beginning of dismantling to the completion of the replacement of the coke pusher rod, it took a total of 82 hours online. The 80t crane was used continuously for 60 hours, which took about 260 man-hours. It also has a big impact on production
