Abstract
The present invention relates to a kind of installation method of last furnace shell, step 1：Offline assembled outrigger platform；Step 2：Assembled integral outrigger platform is arranged on to the outside of furnace body frame using crane, outrigger platform and furnace body frame are connected firmly；Step 3：Sliding rail is laid in outrigger platform both sides；Step 4：Offline assembling sliding trolley；Step 5：By the sliding trolley assembled with crane integral hoisting to outrigger platform after the completion of sliding rail laying；Step 6：When furnace shell is installed, furnace shell is hoisted to above sliding trolley using crane, sliding trolley is then slid onto by blast furnace installation site by winding plant and installed.The present invention is quick and convenient simple by crane integral installation.
Description
Technical field
The present invention relates to the installation method of a kind of installation method, specifically last furnace shell.
Background technology
Generally conventional blast furnace overhaul, in the case where retaining furnace body frame, furnace shell is all by furnace roof driving point when installing
Block is installed, and not only efficiency is low, and the duration is also slow.
The content of the invention
It is contemplated that the defects of overcoming prior art, there is provided a kind of installation method of last furnace shell, it is overall by crane
Installation, it is quick and convenient simple.
In order to solve the above-mentioned technical problem, the present invention is realized in：
A kind of installation method of last furnace shell, it is characterised in that it comprises the following steps：
Step 1：Offline assembled outrigger platform；
Step 2：Assembled integral outrigger platform is arranged on to the outside of furnace body frame using crane, by outrigger platform and stove
Body framework is connected firmly；
Step 3：Sliding rail is laid in outrigger platform both sides；
Step 4：Offline assembling sliding trolley；
Step 5：By the sliding trolley assembled with crane integral hoisting to outrigger platform after the completion of sliding rail laying；
Step 6：When furnace shell is installed, furnace shell is hoisted to above sliding trolley using crane, then will be slid by winding plant
Dolly slides onto blast furnace installation site and installed.
The installation method of described last furnace shell, it is characterised in that outrigger platform described in step 1 includes platform, tiltedly
Support and sliding rail, the platform and furnace body frame outside are connected, and connect diagonal brace between platform and furnace body frame, on the platform
The two side positions laying sliding rail in portion.
The beneficial effects of the invention are as follows：Because the installation of conventional blast furnace overhaul furnace shell piecemeal is typically divided by furnace roof driving
Block is installed, and online installation accuracy control difficulty is big, and operating environment is poor, the quality control difficulty of furnace shell welding is larger, while online
Installation takes substantial amounts of time, long construction period.Solve problem above by this set outrigger platform and sliding trolley device, can
To realize that the whole circle of furnace shell is offline assembled, installed using outrigger platform sliding trolley in place, so as to realize Fast Installation.The device carries
High efficiency of construction, efficiently solve furnace shell piecemeal installation effectiveness it is low problem, substantially reduce the construction period.
By the method, enable the online whole circle installation of furnace shell, it is ensured that the installation accuracy and quality of furnace shell, by frame
Frame sets outrigger platform, then utilizes sliding trolley, it is possible to achieve the whole circle installation of furnace shell, can greatly improve furnace shell erector
Phase, save the duration.
Brief description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of sliding trolley.
Embodiment
As shown in Figure 1：A kind of installation method of last furnace shell, it comprises the following steps：
Step 1：Offline assembled outrigger platform；The outrigger platform includes platform 1, diagonal brace 3 and sliding rail 2, the platform and stove
The outside of body framework 4 is connected, and diagonal brace, the two side positions laying sliding rail of the platform upper are connected between platform and furnace body frame
Road；
Step 2：Assembled integral outrigger platform is arranged on to the outside of furnace body frame using crane, by outrigger platform and stove
Body framework is connected firmly；
Step 3：Sliding rail is laid in outrigger platform both sides；
Step 4：Offline assembling sliding trolley 5；As shown in Figure 2.
Step 5：By the sliding trolley assembled crane integral hoisting to outrigger platform after the completion of sliding rail laying
On；
Step 6：When furnace shell is installed, furnace shell is hoisted to above sliding trolley using crane, then will be slid by winding plant
Dolly slides onto blast furnace installation site and installed.
This method is constructed suitable for the overhaul of blast furnace routine, and can realize that furnace shell is whole by the device encloses the mesh installed online
Mark, so as to improve operating efficiency, the construction period is saved, and furnace shell installation accuracy can be controlled, improve installation quality.
This method, which makes, to be used simply, can be integral in ground processing assembling, then passes through crane integral installation, quick square
Just it is simple.
