A coke oven mainly consists of three parts: the oven body, an openable and closable bottom gate, and a vertically movable mechanism. Additionally, it has a sealing skirt to prevent the leakage of high-temperature flue gas during coke unloading.

[0003] The description of a rotating coke oven maintenance device in the prior art (publication number CN204198656U) mentions that "the maintenance platform is provided with a platform supported by columns, the platform is close to the top edge of the coke oven, a hoisting mechanism is set above the maintenance platform to hoist and replace cast iron liners, and a lifting device is set at the bottom of the coke oven to lift the coke oven so that the bottom gate of the coke oven can be opened for maintenance and replacement of the bottom gate liner." However, the coke oven maintenance device in the prior art cannot stably clamp the upper part of the coke oven at the same time, which may cause it to shake during maintenance, posing certain safety hazards. Moreover, the maintenance platform is inconvenient to assemble flexibly and is not flexible, stable and practical. Utility Model Content
