Description
Technical field
The utility model relates to blast furnace maintenance aid technical field, particularly relates to a kind of blast furnace cooling stave and changes hoisting tool special.
Background technology
Blast furnace cooling stave is the important water-cooled part of blast furnace lining, is arranged on the positions such as the shaft of blast furnace, furnace bosh, bosh, cupola well.Blast furnace can cause in long term high temperature, high pressure production process cooling wall local burn, the cooling wall of damage has a strong impact on the service life of blast furnace and the normal work of blast furnace, thus blast furnace is big or middle repair time can carry out local replacing to the cooling wall of badly broken.
At present, change blast furnace cooling stave and generally adopt hoist ceiling crane or erection winch directly to lift cooling wall, once only lift one piece of cooling wall, first pulled down by the cooling wall of damage, then install at the new cooling wall of lifting, this construction method efficiency is low, time and effort consuming, extends the blast furnace maintenance used time.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of blast furnace cooling stave and changes hoisting tool special, by arranging two cover detent mechanisms at crossbeam two ends, once can lift two pieces of cooling walls, two pieces of cooling walls can be changed simultaneously, greatly improve overhaul efficiency, shorten the maintenance used time.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of blast furnace cooling stave changes hoisting tool special, comprise crossbeam, suspension bracket and be arranged on the detent mechanism at crossbeam two ends, described suspension bracket is inverted V-arrangement framework, two ends, its underpart are fixedly connected with crossbeam end face, its upper end is provided with the connecting bore for being connected with the steel rope of winch, and described suspension bracket is positioned in the middle part of crossbeam.
Described detent mechanism for pulling carrier, described in pull carrier assembly pulley roll with crossbeam and coordinate, described in pull bottom carrier chain block installed by suspension ring.
Described crossbeam is I-beam section, described in the two pairs of assembly pulleys pulled on carrier set up separately and I-beam section both sides, and coordinate with its rolling, described I-beam section two ends are provided with arc buting iron.
The beneficial effect adopting technique scheme to produce is: pull carrier by installation two cover supporting at crossbeam two ends, and and pull the supporting installation chain block of carrier, when dismounting cooling wall, chain block realizes axial location, pull carrier and realize radial location, after winch once lifts and puts in place, use chain block and pull carrier and finely tune, raise the efficiency, and once lift two pieces of cooling walls, carry out the dismounting of two pieces of cooling walls simultaneously, shorten the blast furnace maintenance used time, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model using state schematic diagram;
In the accompanying drawings: 1, crossbeam; 2, suspension bracket; 3, buting iron; 4, carrier is pulled; 5, chain block; 6, cooling wall; 7, last furnace shell; 8, steel wire rope of windlass.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Need in blast furnace maintenance process to change cooling wall, existing replacing options uses chain block or winch to carry out dismounting, at every turn can only dismounting one piece of cooling wall, when installation, because cooling wall quality is larger, chain block or winch is needed to coordinate the position of adjustment cooling wall, frequent operation chain block or winch adjust the position of cooling wall, used time is longer, inefficiency, for this reason, the utility model provides a kind of blast furnace cooling stave as shown in Figure 1 and changes hoisting tool special, comprise crossbeam 1, suspension bracket 2 and the detent mechanism being arranged on crossbeam 1 two ends, described suspension bracket 2 is inverted V-arrangement framework, two ends, its underpart are fixedly connected with crossbeam 1 end face, its upper end is provided with the connecting bore for being connected with steel wire rope of windlass 8, described suspension bracket 2 is positioned in the middle part of crossbeam 1, described detent mechanism for pulling carrier 4, described in pull carrier 4 assembly pulley roll with crossbeam 1 and coordinate, described in pull bottom carrier 4 chain block 5 installed by suspension ring, described crossbeam 1 is I-beam section, other section forms can also be adopted, as long as the installation pulling carrier can be ensured, the described two pairs of assembly pulleys pulled on carrier 4 set up separately and I-beam section both sides, and coordinate with its rolling, and described I-beam section two ends are provided with arc buting iron 3, buting iron is set to arcuate structure, and its axis is vertically arranged, in lifting cooling wall process, effectively prevent beam-end from clashing into and damage intact cooling wall.
Lifting device described in the utility model can according to blast furnace internal diameter size self manufacture, first select crossbeam, suspension bracket according to the weight configuration of blast furnace internal diameter size and cooling wall, pull anchor head and hang and the intensity of bottle gouard moved by hands or specifications and models, the preferred I-beam section of crossbeam, suspension bracket, shelves iron are welded by general steel plate, suspension bracket, shelves iron weld with between crossbeam, suspension bracket is arranged in the middle part of crossbeam, and chain block is hung on and pulls on the lower hook of carrier, so far completes the making of lifting device.
In embody rule process, first a winch is set in blast furnace roof inspection manhole position of platform, and by the mounting hole fixed-link on steel wire rope of windlass end and suspension bracket, winch is utilized to promote lifting device, air tugger promotes traction lifting device to lifting cooling wall position, two pull anchor head dolly and bottle gouard moved by hands and coordinate and carry out radial and axial location, the lower end of chain block hook is mounted with cooling wall, use winch to sling two pieces of cooling walls 6 simultaneously, and lift cooling wall to position to be installed, use two to pull the position that cooling wall finely tuned by anchor head dolly 4 and chain block 5 simultaneously, cooling wall and last furnace shell 7 fixedly mount, complete replacing.
In a word, the utility model by crossbeam two ends, supporting installation two cover pulls carrier, and and pull the supporting installation chain block of carrier, when dismounting cooling wall, chain block realizes axial location, pulls carrier and realizes radial location, after winch once lifts and puts in place, use chain block and pull carrier and finely tune, raise the efficiency, and once lift two pieces of cooling walls, carry out the dismounting of two pieces of cooling walls simultaneously, shorten the blast furnace maintenance used time, time saving and energy saving.
