Abstract
The utility model discloses a blast furnace throat steel brick replacing apparatus. A furnace roof platform is arranged outside the throat of a blast furnace, the dry zone in the furnace shell at the lower portion of furnace throat steel bricks is fixedly connected with a furnace inside platform, a transportation through hole corresponding to the furnace roof platform is arranged on the furnace shell in the dry zone, the furnace roof platform extends into the furnace shell through the transportation through hole, the furnace roof platform positioned in the furnace shell is connected with the furnace inside platform through a support block, a track stretching into the furnace shell is arranged on the furnace inside platform, a mobile dolly is cooperatively arranged on the track, a hanging fulcrum of a furnace inside hoisting device is arranged over the furnace throat in the furnace shell, and a furnace outside hoisting device cooperated with the furnace roof platform is arranged outside the furnace. The blast furnace throat steel brick replacing apparatus has the advantages of simple structure, convenient maintenance of the blast furnace, increase of the maintenance efficiency of the blast furnace, manpower and material resource saving, and improvement of the maintenance safety.
Description
Technical field
The utility model belongs to more changing device of device, particularly a kind of blast furnace throat steel brick that the maintenance iron-smelting blast furnace changes throat armour.
Background technology
Blast furnace throat is in the location, boundary of shaft furnace charging and blast furnace gas rising blowing, and the steel brick is the important composition part of furnace throat, abominable working condition, and the wearing and tearing that make it be subjected to for a long time washing away of high-temperature coal air-flow and expect to flow, the steel brick is yielding, turns in the Yi Xianglu of bottom and sticks up.The throat armour of distortion will affect blast furnace material distribution, be unfavorable for the stable of Gas Flow, cause conditions of blast furnace not normal, reduce furnace processor.The chance of repairing or limiting the production during blast furnace must utilize is carried out blowing out and is changed throat armour.And existing more changing device is as follows: build platform inside furnace and hanging scaffold at the blast furnace throat position, to pass through hanging scaffold after the dismounting of steel brick, the air port of being placed cupola well top by furnace throat is regional, uses jack that the steel brick is transported to tuyere platform from the air port, uses lifting appliance to winch to ground and transports.The shortcoming of this device is: the hanging scaffold building amount in the stove is large, consuming time, and general hanging scaffold is built waste repair time 10-12h, the steel brick is put upside down to hanging scaffold by platform inside furnace after removing simultaneously, be transported to the place, air port by the lifting of hanging scaffold again, have bad luck loaded down with trivial details, the waste repair time.In the stove to stove, have bad luck difficulty.The dismounting of hanging scaffold will be wasted repair time 8-10h.The people stands in and can not get safely on the hanging scaffold ensureing simultaneously.
Summary of the invention
The purpose of this utility model is to provide more changing device of a kind of blast furnace throat steel brick, and it is rational in infrastructure, can make blast furnace maintenance work convenient, improves the efficient of blast furnace maintenance, saves the man power and material, improves the security of service work.
The purpose of this utility model is achieved in that more changing device of a kind of blast furnace throat steel brick, be included in the last furnace shell and be fixed wtih the steel brick by backing ring and the ribbed slab device suspension that arranges, throat platform in the blast furnace throat outer setting, affixed the platform inside furnace at place, the furnace shell Nei Gan district of throat armour bottom, and at the furnace shell of doing the place, district the transportation through hole corresponding with throat platform is being set, throat platform extends in the furnace shell by the transportation through hole, the throat platform that is positioned at furnace shell is connected with platform inside furnace by back-up block, at platform inside furnace the track that stretches in the furnace shell is being set, cooperate in orbit travelling car is installed, in furnace shell furnace throat above the suspension fulcrum that plays hanging apparatus in the stove is being set, outside stove, arranging with stove that throat platform matches outside lifting appliance.
When utilizing the utility model maintenance blast furnace, in the process that throat armour is changed, the steel brick is directly poured out from the furnace throat bottom, because furnace inner space is narrow and small, pour out consuming time from cupola well, pour out from the transportation through hole of furnace throat bottom, reduced having bad luck the time in stove, the bright spot of the technical program is, the steel brick can be transported stably and transport, depend primarily on the invention of transporting trolley and rail set thereof, because with track, dolly is provided with four-wheel, travelling speed is exceedingly fast, operate steadily, track on the throat platform connects suspension fulcrum and outer lifting place of stove in the stove, and it can make steel brick that the steel brick disassembles by being transported to easily outer lifting place of stove in the stove.Otherwise, also can make the outer steel brick of stove by outer lifting place of stove, place on the dolly, safe, reliable and convenient is transported in the stove.The suspension that the steel brick is installed is backing ring device and ribbed slab device fixedly, utilizes spirit-leveling instrument to find out end face absolute altitude on the damaged steel brick backing ring gusset at the body of heater inner platform, and marks water line and furnace throat circumference equal dividing line is crossing, determines the damaged position that goes out gusset.The outer lifting appliance of stove can use suitable suspender.
The utility model is rational in infrastructure, utilizes the utility model to change the service work of blast furnace throat steel brick, makes blast furnace maintenance work convenient, has improved the efficient of blast furnace maintenance, has saved the man power and material, has improved the security of service work.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.Fig. 1 is the structural representation of working process of the present utility model.
