Coke oven door turning device and turning method

Abstract

The invention discloses a coke oven door overturning device. The coke oven door overturning device comprises a base, a lifting device and a rotary device, wherein the lifting device is fixed on the base, the driving end of the lifting device is connected with the moving base, the upper portion of the moving base is connected with the rotary device, the driving end of the rotary device is connected with one end of a connecting sleeve, and the rotary device can drive the connecting sleeve to rotate. The other end of the connecting sleeve is connected with the oven door. The lifting device comprises a jack, the jack is provided with a lifting rod used for operating, and the driving end of the jack is fixedly connected with the moving base. The invention further discloses a coke oven door overturning method. The coke oven door overturning device has the advantages that the overturning device overturns the oven door through the connecting sleeve and is stable and controllable, the defects of conventional methods are overcome, secondary damage of the coke oven door edges is avoided, quality of the oven door is guaranteed, and the foundation is laid for normal operation of a coke oven.

Description

technical field [0001] The invention relates to the technical field of coke oven door construction, in particular to a coke oven door turning device and a turning method. Background technique [0002] The inner side of the coke oven door is facing the inside of the furnace body, and the outer side is facing the outside. Various other mechanisms are usually installed on the outer side of the furnace door. When loading, in order to avoid damage to the structure on the outer side of the furnace door and the car plate, the inner side of the furnace door faces down and the outer side of the furnace door faces up. In actual production, the inner surface of the furnace door needs to be inlaid with refractory bricks. Since the inner surface of the coke oven door is facing downward during transportation and loading, it needs to be turned over for construction at this time. The door of the coke oven is large in size and high in quality. At present, cranes and wire ropes are often us...

AI Technical Summary

Problems solved by technology

The door of the coke oven is large in size and high in quality. At present, cranes and wire ropes are often used for turning over construction. The construction process is cumbersome. During the door turning process, it is easy to appear that the edge of the furnace door is squeezed and deformed by the steel wire rope, resulting in the stagnation of the construction process; it takes a long time for the crane to turn over a single furnace door, and the number of furnace doors in a coke oven is about 100 pieces , high labor intensity and very low construction efficiency

In addition, the use of hoisting and flipping has high professional requirements for the operators, and the construction quality is difficult to guarantee, and there are certain safety hazards
