Abstract
The utility model discloses a special lifting appliance for changing seals of COREX ironmaking furnace spiral cooling water devices, which comprises a rectangular bottom plate, an H-shaped beam rail, two vertical rods, a transverse beam and four self-locking caster wheels, the middle portion of one side of the rectangular bottom plate is equipped with a rectangular gap, the four self-locking caster wheels are arranged at four angles of the bottom plate, the two vertical rods are perpendicularly arranged at the middle portion of two sides which are adjacent to the side of the rectangular bottom plate equipped with the gap, two ends of the transverse beam are arranged on the top portions of the two vertical rods, and the H-shaped beam rail and the transverse beam are in cross connection under the middle portion of the transverse beam. The lifting appliance does not need setting up scaffolds and lifting derrick masts, can realize fast and reliably mounting, dismounting and changing seal parts of DRI spiral conveyor cooling water devices, increases lifting safety and lifting efficiency of the cooling water devices, largely shortens changing time of the seal parts, improves operation environment of maintainers, increases work efficiency and reduces labor intensity.
Description
Technical field
The utility model relates to the special hanger that a kind of COREX iron-smelting furnace spiral chilled water unit sealing is changed.
Background technology
The COREX stove is state-of-the-art in the world at present smelting equipment, and the DRI conveyor screw is that the iron ore (sponge iron DRI) after the reduction in the shaft furnace is delivered in the melting gasification furnace, and it is the core mechanical equipment in the whole C OREX stove production process.Being sealed in the operational process of conveyor screw chilled water unit because wearing and tearing often need the scene to change.Because the about 2000mm of DRI conveyor screw front end is deep among 700 ℃-900 ℃ the high temperature furnace charge.The dismounting chilled water unit will certainly cause the DRI conveyor screw to cut off the water supply, and therefore requires to finish the chilled water unit leak free in the shortest time and more changes jobs.The DRI conveyor screw all adopted the form of scaffolding erecting at the replacing chilled water unit in the past, considered can not use suspender on the scaffold from security standpoint, and therefore also needing to build the handling gin pole comes handling appliance.So not only influence construction speed, also had potential safety hazard simultaneously.
Since COREX-the 3000th, the most advanced world iron-smelting process, maintenance at COREX stove nucleus equipment, be domestic trial first, the sealing of not changing the DRI conveyor screw under the shaft furnace emptying situation is to attempt for the first time, there is not this precedent abroad yet, because temperature height in the stove, the sealing of conveyor screw backwater cavity just is in the state of cutting off the water supply in case open cavity, and this will find the solution the terminal backwater lid of body conveyor screw and change tightening seal washer and need shorten repair time after cutting off the water supply as far as possible.
And in this process the lifting backwater to cover this maintenance process the most key, how rationally the fast speed hoisting process is the technical barrier of maintenance under the on-the-spot limited space environment of COREX stove.Also be to change spiral backwater lid leak free core service technique.
Summary of the invention
Technical problem to be solved in the utility model provides the special hanger that a kind of COREX iron-smelting furnace spiral chilled water unit sealing is changed, utilize this suspender to scaffold erecting and the handling gin pole, can realize quick, the failure-free dismounting of DRI conveyor screw chilled water unit sealing, the safety and the efficient of chilled water unit lifting have been improved, shorten the replacing time greatly, improve the operating environment of service personnel, increased work efficiency, reduced labour intensity.
For solving the problems of the technologies described above, the special hanger that the sealing of the utility model COREX iron-smelting furnace spiral chilled water unit is changed comprises rectangular base plate, H-girder track, two vertical rods, crossbeam and four band self-locking castors, described rectangular base plate one middle side part has a rectangular indentation, described four band self-locking castors are located at four jiaos of described base plates, described two vertical rods are vertical at the middle part that described rectangular base plate has the adjacent both sides of breach, the top of described two vertical rods is located at described crossbeam two ends, and described H-girder track and described crossbeam are the below that cross is connected in the crossbeam middle part.
For making the H-girder orbitally stable, this suspender also comprises two struts, and described two struts are located at respectively between the end of the two ends of described crossbeam and described H-girder track.
For guaranteeing the stability of whole suspender, the junction of above-mentioned vertical rod and described base plate and crossbeam is provided with reinforced rib.
Above-mentioned rectangular base plate can be made up of square steel rectangular frame of making and the rectangular plate of being located on the rectangular frame.
Because the special hanger that the sealing of the utility model COREX iron-smelting furnace spiral chilled water unit is changed has adopted technique scheme, promptly make a rectangular base plate as workplatform, rectangular base plate is provided with two vertical rods and crossbeam constitutes a goal frame, crossbeam is provided with the H-girder track, and rectangular base plate one side has a rectangular indentation; During the work of this suspender, at first make this suspender in place in rectangular base plate notch alignment conveyor screw chilled water unit pipeline, on the H-girder track hanging wheel is set, dismantle the cooling water pipe of chilled water unit then, and the cooling water pipe of pulling down is fixed in the vertical rod of suspender, dismantle the chilled water unit bolt then, chilled water unit is shifted out along the H-girder track cross level by hanging wheel, carry out the replacing of sealing member after chilled water unit moves on the rectangular base plate.Utilize this suspender to scaffold erecting and the handling gin pole, can realize quick, the failure-free disassembling, assembling and replacing of DRI conveyor screw chilled water unit sealing member, the safety and the efficient of chilled water unit lifting have been improved, shortened the replacing time of sealing member greatly, improved the operating environment of service personnel, increase work efficiency, reduce labour intensity.
