Jacking and sliding equipment special for blast furnace

Abstract

The invention provides jacking and sliding equipment special for a blast furnace. The equipment comprises a plurality of sliding grooves, sliding shoes, push-pull devices, transverse moving assembliesand jacking assemblies; wherein the plurality of sliding grooves are arranged side by side at intervals, the plurality of sliding shoes are arranged in each sliding groove, and the sliding shoes arearranged in the sliding grooves in a sliding mode; at least one sides of the sliding shoes in the sliding grooves are provided with the push-and-pull devices, the push-and-pull devices are selectivelyclamped on the sliding grooves, and the push-and-pull devices are connected with the sliding grooves in a sliding mode; the sliding shoes are provided with the plurality of transverse moving assemblies. and the sliding shoes are further provided with the jacking assemblies. According to the jacking and sliding equipment, the push-pull devices are selectively clamped on the sliding grooves, the sliding shoes are intermittently pushed to move in the longitudinal direction of the sliding grooves so that intermittent long-distance movement of the sliding shoes can be achieved; the transverse moving assemblies is used for supporting a blast furnace shell and driving the blast furnace shell to transversely move so as to adjust the transverse position of the blast furnace shell; and the blast furnace shell is jacked up through the jacking assembly so that the height position of the blast furnace shell can be adjusted.

Description

technical field [0001] The invention relates to the technical field of metallurgical engineering, in particular to a special jacking and sliding equipment for blast furnaces. Background technique [0002] At present, there are 23 blast furnaces with an area of ​​more than 4000m3 in my country. According to the calculation of the first-generation furnace age of 15-20 years, about 50% of the blast furnaces with an area of ​​more than 4000m3 will be overhauled in the next five years. The traditional blast furnace overhaul construction technology is dismantling and installation in parts , The amount of engineering demolition or installation reached tens of thousands of tons. This method has relatively large defects, mainly including: large amount of online construction work, many high-altitude operations, difficulty in connecting various processes, large interaction of cross-operations, many uncertain factors, long online construction time, and occupation of large lifting equipme...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention proposes a special jacking and sliding equipment for blast furnaces, aiming to solve the problems that the existing sliding shoes have relatively slow push-pull speed during use, and the hydraulic system is too hot to work continuously.
