Description

Technical Field

[0001] The present invention relates to the technical field of coke oven door maintenance, and particularly to a connector for transferring a coke oven door. Background Art

[0002] During the production process of a coke oven, it is often necessary to repair the main parts such as the knife edge, web, lining brick, and spring of the coke oven door. The Chinese invention patent with the authorization announcement number CN 106967447 B discloses "a rotating frame for a coke oven door repair station and its use method". The rotating frame includes a main frame and a door roller stopper, a door body stopper, a door hanging rod and / or a guide ear stopper, and a door bolt stopper respectively arranged on the main frame; the middle part of the main frame is a accommodating space for the coke oven door, and the upper and lower ends of the main frame are respectively coaxially provided with rotary shafts for cooperating with the power mechanism of the coke oven door repair station to realize the lifting and rotating actions of the main frame and the coke oven door. During maintenance, the coke oven door is removed by a coke oven vehicle and sent to the door repair station, and the coke oven door is hung on the rotating frame of the coke oven door repair station. The coke oven door rotates with the rotating frame for repairing and detecting the knife edge of the door. However, its rotating frame is a quadrilateral frame structure, which seriously wraps and blocks various parts of the coke oven door. It is very difficult to repair and replace parts such as the web, door bolt, and spring. It is only possible to remove the coke oven door from the rotating frame and place it on the ground for repair and replacement.

[0003] The Chinese invention patent with the authorization announcement number CN 104388102 B discloses "a rotating lifting device for repairing a coke oven door", including a main frame, a docking mechanism, a rotating mechanism, a lifting mechanism, a traveling mechanism, and a control system. The docking mechanism and the rotating mechanism are installed on the main frame. The main frame is connected to the traveling mechanism through the lifting mechanism. The traveling mechanism can move along the ground guide rail, and the control system controls each mechanism to complete the docking and clamping, rotation, lifting, lowering actions of the coke oven door and the traveling action of the traveling trolley. The main frame with a single-sided frame structure is more convenient for repairing each part of the door, and the repair efficiency is high. The docking mechanism consists of an upper docking head, a lower docking head, and a docking driver. The upper docking head and the lower docking head are respectively fixed on the inner side of the extending arm of the main frame and can complete the docking and clamping actions on the upper and lower ends of the coke oven door body casting under the drive of the docking driver. However, it does not record how the main frame is specifically docked with the coke oven door. Summary of the Invention
