Abstract
The utility model provides a trolley for changing tuyeres. The lower ends of two support plates are respectively provided with a wheel, the upper ends thereof are respectively provided with a beam, and a support pole is arranged on the back ends of the beams; and two connecting plates are arranged in tandem on the inner side of the upper parts of the support plates, the centre of the two connecting plates is fixed with a tappet extending forward, transverse braces are arranged between the beams, and diagonal braces are arranged between the support plates and the beams. The utility model has simple structure and low cost, is convenient to use, can shorten the time for changing the tuyeres by over half, improves the work efficiency, reduces the labour intensity, obviously lessens the number of cooperating staff for changing the tuyeres, and can double the number of continuous tuyeres changing at one step by workers. Particularly, the trolley can help to keep an enough distance between operators and carbon coke in front of a blast-furnace tuyere, and thereby preventing safe accidents.
Description
Technical field
The utility model belongs to ironmaking auxiliary facility field, changes the used dolly in air port during particularly a kind of blast furnace staying.
Background technology
Need change the air port during blast furnace staying.At present, what domestic most ironmaking manufacturer all taked all the time is the mode that manually hand-held crowbar changes the air port, its tool construction is simple, also use and very require great effort, therefore the time of changing an air port is longer, labour intensity is very big, and needs 6-10 people's while coordinating operation to finish.Especially along with the continuous progress of blast furnace maximization, the also corresponding increase along with improving constantly of heat size of the air port weight of blast furnace makes the operator change 2-3 air port continuously and has just exhausted muscle power basically.If run into bad many of blast-furnace tuyere, in blast furnace, leak when serious, not only waste time and energy, cause operator's muscle power overdraw; And because the outside flame seedling in air port brings very big difficulty, the careless slightly security incident that very easily takes place for the replacing air port.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple in structure, and is easy to use, can change the air port fast, increases work efficiency, and reduces labor intensity, and that avoids security incident changes the air port dolly.Concrete scheme is:
A kind of air port dolly that changes is by back up pad, wheel, tappet, Che Liang and hold up bar to form; Two back up pad lower ends wide at the top and narrow at the bottom respectively are equipped with wheel, and the upper end connects a car beam respectively, and the Che Liang back is provided with holds up bar; One in front and one in back be provided with two web plates in the inboard on back up pad top, two web plate centres are fixed with a tappet that stretches out forward.
Have bearing on the described wheel.
Be provided with transverse brace between described two car beams; Be provided with brace between back up pad and the car beam.
Described tappet height is identical to the distance between the blast-furnace tuyere medullary ray with the tuyere platform upper surface.
Positively effect of the present utility model is:
The utility model is simple in structure, and is cheap, but self manufacture; And easy to use, accelerate replacing speed, shorten that to change the air port time over half, increase work efficiency, reduce working strength of workers, make and collaboratively change the air port personnel and obviously reduce, workman's one-time continuous is changed inlet number and is doubled.Especially adopt the car beam of lengthening, and utilize lever principle, make the preceding coke of operator and blast-furnace tuyere keep enough distances, thereby stopped to occur the possibility of security incident.
Description of drawings
Accompanying drawing is for changing air port vehicle structure stereographic map.
Among the figure: wheel 1, back up pad 2, tappet 3, web plate 4, transverse brace 5, brace 6, car beam 7, hold up bar 8.
Embodiment
By accompanying drawing as seen, the utility model changes the air port dolly mainly by wheel 1, back up pad 2, tappet 3, web plate 4, car beam 7 with hold up bar 8 to be constituted.Wheel 1 is a solid rubber wheel, and is inlaid with bearing on the wheel 1.Every back up pad 2 all is to be welded by 2 steel plates wide at the top and narrow at the bottom, leaves spacing between 2 steel plates.Tappet 3 is that employing Φ 80mm, length are the steel pipe manufacturing of 2.5m.Car beam 7 length are * * m.
Two wheels 1 that bearing is housed are installed in two back up pad 2 lower ends respectively and leave in the middle of 2 steel plates of spacing, and with bolt tight.One in front and one in back weld two round-meshed web plates 4 in the inboard on back up pad 2 tops, the afterbody that is inserted in the tappet 3 in the circular hole is welded on respectively on the web plate 4 of front and back.According to the tuyere platform upper surface to the distance between the blast-furnace tuyere medullary ray, the height of tappet 3 is defined as * * m.A car beam 7 is respectively welded in the upper end of back up pad 2, and car beam 7 back arranged transverselys one are held up bar 8.For gaining in strength, between two car beams 7, be welded with transverse brace 5; Between back up pad 2 and car beam 7, also weld simultaneously a brace 6.
Claims (4)
1. one kind is changed the air port dolly, it is characterized in that, by back up pad, wheel, tappet, Che Liang and hold up bar to form; Two back up pad lower ends wide at the top and narrow at the bottom respectively are equipped with wheel, and the upper end connects a car beam respectively, and the Che Liang back is provided with holds up bar; One in front and one in back be provided with two web plates in the inboard on back up pad top, two web plate centres are fixed with a tappet that stretches out forward.
2. the air port dolly that changes according to claim 1 is characterized in that, has bearing on the described wheel.
3. the air port dolly that changes according to claim 1 is characterized in that, is provided with transverse brace between described two car beams; Be provided with brace between back up pad and the car beam.
4. the air port dolly that changes according to claim 1 is characterized in that, described tappet height is identical to the distance between the blast-furnace tuyere medullary ray with the tuyere platform upper surface.
