A blast furnace top flange alignment device and method

Abstract

A blast furnace top flange alignment device and method, the device comprises: a flange connection component for connecting with a furnace top flange; the flange connection component is connected with the furnace top flange; a target plate is fixed an assembly for carrying a target plate; the target plate fixing assembly is connected with the flange connection assembly; an observation assembly is used to observe the target plate; the observation assembly is arranged on the flange connection assembly and is located in the directly above the target plate. The device and method for aligning the top flange of a blast furnace provided by the present application can display the deviation value of the flange center in real time through external electronic equipment, which is convenient for adjusting the flange position, and the adjustment accuracy is greatly improved; it avoids the traditional method. Using the fixed frame and operating platform for hanging steel wires, the investment in measures is less and the safety is improved; the final value of alignment can be stored as a picture, which is highly intuitive and easy to view.

Description

technical field [0001] The invention belongs to the technical field of metallurgical engineering construction, and particularly relates to a blast furnace top flange alignment device and method. Background technique [0002] In the prior art, the metallurgical industry often adopts the method of "checking the deviation between the center line of the furnace top flange and the furnace bottom center line with a steel ruler for pulling wires and hanging wire drop". The height difference is between 30 meters and 50 meters. The weight of ordinary line sinks is small and cannot be measured. Usually, special line sinks are made before flange installation. The height difference to the center of the flange is 30-50 meters, and a steel wire pendant is used. Every time the position is adjusted, the wire pendant will oscillate. It takes a long time to stabilize, the measurement speed is slow, and the accuracy is low; (3) The steel wire hanging method In the Lan center, an operating pla...

Problems solved by technology

[0002] In the prior art, the metallurgical industry often adopts the method of "checking the deviation between the center line of the furnace roof flange and the center line of the furnace bottom" by "checking the center line of the furnace roof flange and the furnace bottom with a steel ruler for drawing and hanging wires". The height difference is between 30m and 50m. It is impossible to measure with the ordinary wire pendant due to its small weight. Usually, a special wire pendant is made before the flange is installed. The special wire pendant is a non-standard part, and the processing accuracy is not easy to guarantee; The height difference to the center of the flange is 30-50 meters, and the steel wire pendant is used. Every time the position is adjusted, the pendant will swing, and it will take a long time to stabilize, the measurement speed is slow, and the accuracy is low; (3) the steel wire hangs on the French In the Lan Center, an operating platform needs to be set up before the steel wire is hung, which increases the cost and is not easy to guarantee the safety
