Abstract

The invention relates to the technical field of dry quenching of coke, specifically to a special trolley used as a mobile coke pot maintenance station for maintenance of a rotary coke pot. The specialtrolley is composed of trolley wheel sets, a trolley frame, guiding fixed supports, coke pot bases and coke pot spreader bases, and becomes a coke pot maintenance station which utilizes a dry-quenched coke lifting machine to take and deliver the rotary coke pot and can move on the rails of a transfer platform and a lifting machine headframe. The trolley frame steel frame structure resembling a shoe-shaped silver ingot; the central part of the trolley frame is concave; two ends of the trolley frame respectively have a platform structure. The trolley wheel sets are respectively arranged on thelower parts of the platforms located at two ends of the trolley frame. The guiding fixed supports, the coke pot spreader bases and the coke pot bases are successively and symmetrically arranged on theupper parts of the platforms located at two ends of the trolley frame from exterior to interior. The special trolley provided by the invention realizes safe, convenient and rapid coke pot maintenanceoperation, can greatly reduce the labor intensity of maintenance personnel, successfully solves the current embarrassing situation that a ground coke pot maintenance station needs a large-tonnage crane with 300 tons or above for coke pot maintenance operation, and saves a large amount of coke pot maintenance cost.

Description

technical field

[0001] The invention relates to the technical field of coke dry quenching, in particular to a special trolley for rotating coke tank maintenance as a mobile coke tank maintenance station. Background technique

[0002] The rotating coke tank is used to transport the 1000±50℃ red coke pushed out from the coke oven carbonization chamber, cooperate with the electric locomotive, CDQ hoist and other equipment, and put the red coke into the CDQ furnace to complete the coke quenching process. Each CDQ device is equipped with 3 sets of rotating coke tanks (cars), which operate in the mode of 2 open and 1 standby, and the spare coke tanks are parked on the track of the car moving platform. During the production process, the coke tank is always operated at high temperature, and the coke tank liner and the steel structure of the main body are frequently damaged, so it is necessary to go offline frequently for liner replacement, structural reinforcement and other maintena...
