Description
Technical field
The utility model is related to a kind of blast furnace building construction equipment, and more specifically, the utility model is related to one kind and is used for
The hoistable platform of blast furnace building construction.
Background technology
Those skilled in the art know that the overhaul of blast furnace has the characteristics of duration is tight, the amount of building by laying bricks or stones is big, when being built by laying bricks or stones due to blast furnace
Brick amount is larger, and building construction is relatively difficult, iron mouthful when especially, air port size it is smaller, cause some prefabricated sections can not be from iron
Enter stove at mouth, air port, therefore, material, which enters stove, turns into the problem of construction.
In order to solve this problem, existing conventional method is using bosh protection canopy build by laying bricks or stones and feed in stove, then
To be hung to using hoist engine under prefabricated section more than masonry of well, bosh protects canopy to set up scaffold masonry heater in stove again after removing
Abdomen is to furnace throat weatherable materials.
It is not only cumbersome, take but this traditional method is limited more, it is necessary to repeatedly lifting is had bad luck and scaffold is set up
When, and labor intensive, machinery can not also ensure the in liberal supply of building materials in stove.
Utility model content
The purpose of this utility model is exactly to solve the problem of above prior art is present, and provides a kind of for blast furnace for this
The hoistable platform of building construction.It is no longer cumbersome time-consuming that the application of the technology can make the overhaul of blast furnace construct, and reduces artificial, machinery
Consuming, and multilayer operation can be carried out simultaneously, so as to shorten construction period, fully ensure blast furnace builds efficiency by laying bricks or stones.
Technical solutions of the utility model are：
A kind of hoistable platform for blast furnace building construction, including the crossbeam and longeron structure being crossed-over by several
Into bracket, be uniformly arranged several hangers that the bracket is connected by connecting plate on the circumference of the bracket, described hangs
It is provided with and is connected with described connecting plate and the first vertical reinforcement on ear, circle between the external diameter and blast-furnace bosh of the bracket
Several support beams of Zhou Junbu and four girders, are set respectively between two adjacent support beams or adjacent girder and support beam
There is the second reinforcement, the upper surface of the bracket is provided with supporting plate.
Crossbeam, longeron and support beam described in several make by channel-section steel.
The quantity of the support beam is at least 8.
Girder described in four constitutes stretching structure by channel-section steel and the channel bar being arranged in the channel-section steel.
The quantity of the hanger is at least 6.
The radius of lifting hole(eyelet) is 50mm on the hanger.
The beneficial effects of the utility model are：
(1) it is easy to draw materials, and makes simple, fund input is less.
(2) by the ingenious combination with lever hoist, achievable workbench moving freely in blast-furnace bosh, and by
Four girders that channel-section steel and the channel bar being arranged in the channel-section steel are constituted can manually realize telescopic variation, so as to ensure freedom
Mobile workbench diameter can change with the change in size of bosh internal diameter so that building work by laying bricks or stones becomes light, quick.
(3) position of supporting plate can be limited by the latticed bracket being welded of crossbeam and longeron, so as to ensure that work is put down
Steady status of the platform in lifting process, it is ensured that the personal safety of workmen.
(4) rational deployment of hanger, it is ensured that steady, safety of the operating platform in lifting process, it is to avoid single
The danger of platform rotation can occur for lifting rope lifting, play a part of escorting for safety in production.
(5) large scale prefabricated piece of handling disposably can be simultaneously subjected to furnace bottom simultaneously in place and bosh protects multilayer more than canopy to make
Industry, so as to solve the problem that insoluble construction period always is tight, personnel's efficiency of construction is wasted.
