Furnace stay fixing device used for replacing coke oven cross brace

Abstract

The invention provides a furnace stay fixing device used for replacing a coke oven cross brace. The furnace stay fixing device comprises a cross beam (2), a nut (4), a compression spring (5), a connecting piece (7) and a pull rod (8). The furnace stay fixing device is characterized in that the length of the cross beam (2) is not less than twice of the distance between two adjacent furnace stays, a through hole is formed in the middle of the cross beam (2), supporting leg parts (21) are arranged at two ends of the cross beam (2), and the distance between the supporting leg parts (21) and the through hole is equal to the distance between two adjacent furnace stays; the pull rod (8) passes through the through hole of the cross beam (2); the nut (4) is in threaded connection with one end of the pull rod (8); the connecting piece (7) is positioned at one end of the pull rod (8) far away from the nut (4) for connecting the furnace stays with the pull rod (8); and the compression spring (5) sleeves the pull rod (8), one end of the compression spring (5) is butt-jointed with the nut (4), and the other end of the compression spring (5) is butt-jointed with the cross beam (2). The furnace stay fixing device provided by the invention can reduce the impact of replacement of the cross brace on the normal production of a coke oven, shorten the replacement time, and improve the security of a replacement process.

Description

technical field [0001] The invention relates to the technical field of coke oven equipment, in particular to an oven column fixing device for replacing horizontal braces of coke ovens. Background technique [0002] A coke oven is an oven, usually constructed of refractory bricks and blocks, used to convert coal to produce coke. Furnace protection equipment should be installed on the outside of the coke oven masonry, and the potential energy of the adjustable spring can be used to continuously apply sufficient, evenly distributed and reasonable protective pressure to the masonry, so that the masonry can still maintain its self-expansion and external force. Integrity and strictness, so as to ensure the normal production of the coke oven. [0003] Furnace protection equipment includes furnace door frame and protection plate, furnace column, vertical and horizontal braces, springs and furnace door, etc. The furnace column is welded with I-beam or channel steel, or it can also ...

Problems solved by technology

Yet, because above-mentioned tool operation crosses the coal car track on furnace top, so can only be carried out under the situation that coal car stops, can influence coke oven normal production like this, and, because furnace top surface temperature is high, especially the Near the coal mouth, the steel wire rope and chain hoist components will be deformed by heat, and the fixing effect on the furnace column is not good, and there are also potential safety hazards
