An online deformation trimming device and trimming method for the coke guide grid of a coke blocking vehicle

Abstract

The invention provides an online deformation repairing device for a coke guiding grid of a coke barrier vehicle. The online deformation repairing device comprises two units which are arranged on two sides of a coke guiding grid (4) and have the same structure, wherein each unit comprises two hand wheels (1), two screw rods (2), two movable top blocks (3), a stander (5) and two fixed nuts (6); one ends of the two screw rods (2) penetrate through the stander (5) and are respectively inserted into round holes of the two movable top blocks (3), and one three-claw hand wheel (1) is welded to each of the other ends of the two screw rods (2); and the two fixed nuts (6) are welded to the stander (5). The online deformation repairing device has the advantages of simple structure, convenience in operation and low investment; and the deformation recovery state of the coke guiding grid can be relatively good, the time and the force are saved, a lot of maintenance cost is saved, the repairing time is greatly shortened, the production risk caused due to long-term repairing of the coke barrier vehicle is eliminated, and the stable production of a coke oven is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coke oven equipment in the coking industry, in particular to an online deformation trimming device and a trimming method for a coke guide grid of a coke holding vehicle. Background technique [0002] The coke blocking car is the supporting equipment of the coke oven. It generally runs on the rails on the coke side of the coke oven. It is also responsible for transporting the furnace door and the furnace door frame that need to be repaired. The function of the coke guide grid is to move forward the coke guide grid to align with the carbonization chamber that opens the furnace door, so that the coke guide grid can catch the coke-side furnace frame and move the coke guide grid from the charcoal chamber. The coke at a temperature of about 1000 degrees Celsius pushed out by the coke oven machine is guided to the quenching car. After the coke guide is completed, the coke guide grid is retracted to the original ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned defects in the current method of processing the coke guide grid after deformation, and to provide an online deformation and repair device for the coke guide grid of the coke arresting vehicle, so as to ensure that the coke guide grid of the coke arresting vehicle is damaged, expanded and deformed. Finally, the goal of preventing further deterioration of the deformation and quickly repairing the deformation can be achieved without offline disassembly, which saves the repair cost of the coke guide grid, greatly shortens the maintenance time, and reduces the risk of coke oven production
