Abstract
The utility model discloses a quick removing and restoring device of a hot wind hood of a low carbon sintering machine. The quick removing and restoring device consists of roller seats, rollers, pin rolls and square steel. Two steel plates provided with pin roll aperture are welded on an upper steel plate to form the n-shaped roller seat. The roller is installed in the roller seat through the pin roll. Four roller seats with the rollers are respectively welded on the front and rear ends at the lower edge on both sides of the hot wind hood and are in mirror symmetry with the vertical central line of a sintering trolley and located in a same plane. The notches of the rollers are needed to be relatively compactly contacted with the plane on the square steel in a matched manner. The square steel is welded on a central line of a beam plane formed by two channel beams on H-sectional bars of a hot wind hood installation base bracket on both sides as a guide rail for moving the hot wind hood. The quick removing and restoring device of the hot wind hood of the low carbon sintering machine provided by the utility model has the advantages that the removing and restoring overhaul quality and speed of the hot wind hood can be effectively improved, the overhaul time of the sintering machine is further shortened, and the construction cost is lowered.
Description
Technical field
The utility model belongs to technical field of metallurgical equipment, be a kind of low-carbon (LC) sintering machine air bells cap fast dismantling specifically except and recovery device, be applied to sintering pallet and sealing chute maintenance construction behind the metallurgical low-carbon (LC) Modified Sintering Technology.
Background technology
In metallurgy sintered engineering maintenance construction, often can run into through the transformed sintering pallet of low-carbon technology and sealing chute maintenance task at present.Must remove the hermetically sealed air bells cap on chassis top before the maintenance, too much because of air bells cap top hot air duct, caliber is excessive, can only spend a large amount of pipeline time of removing could remove air bells cap, also need carry out pipeline after the maintenance recovers, therefore cause the stop production to overhaul time long, a large amount of inputs of human and material resources and construction machinery cause construction cost too high in the time of also can causing maintenance.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned shortcoming that exists for prior art, provide a kind of low-carbon (LC) sintering machine air bells cap fast dismantling to remove and recovery device, effectively improve repair quality and speed that air bells cap is removed, recovered, further shorten the sintering machine repair time, reducing construction cost.
The purpose of this utility model is achieved like this: by to existing air bells cap transformation or before carrying out the transformation of sintering machine low-carbon technology, one group four low-carbon (LC) sintering machine air bells cap fast dismantlings are installed when making hermetically sealed air bells cap are removed and recovery device.This device is comprised of roller mount, roller, bearing pin and square steel.First with two Plate Weldings that have the bearing pin aperture on the steel plate of top, form " door " shape roller mount, by bearing pin roller is installed in the roller mount.The four rolling seat that roller will be housed again is welded on respectively end, bead front and back under the air bells cap both sides, and the welding position requires that the pallet longitudinal centre line is mirror image and is symmetrical arranged, and in one plane.The notch of roller require with square steel on the plane cooperate relative close contact.At last square steel is welded on the crossbeam plane centreline that the double flute steel on the air bells cap mount pad support H shaped steel of both sides forms, as the guide rail of Mobile hot air cover.
Before the use, be coated with sufficient lubricating oil at roller and square steel upper surface.When maintenance sintering pallet and sealing chute construction, first with air bells cap top warm-air pipe flange port disassembling bolts, connecting bolt between every section air bells cap is removed, from the air bells cap near lifting zone begin successively will every section air bells cap to the lifting shift of area, with driving a vehicle air bells cap is moved on to full cock position when shifting the traveling crane holding position onto.After the sintering machine maintenance is finished, the recovery erection sequence of air bells cap and opposite the carrying out of dismounting.Need two people can finish with only resuming work in the dismounting of air bells cap.If before carrying out the transformation of sintering machine low-carbon technology, then air bells cap directly is welded on the double flute steel face, during the sintering pallet maintenance, after first all pipelines of air bells cap top being removed, again welding position, air bells cap bottom is cut open.
Compared with prior art, the utility model low-carbon (LC) sintering machine air bells cap fast dismantling except the advantage with recovery device is: effectively improve repair quality and speed that air bells cap is removed, recovered, further shorten the sintering machine repair time, reducing construction cost.

The specific embodiment
For further describing the utility model, below in conjunction with accompanying drawing to the utility model low-carbon (LC) sintering machine air bells cap fast dismantling except being further described with recovery device.
As shown in the figure, low-carbon (LC) sintering machine air bells cap fast dismantling removes and recovery device, is comprised of roller mount (1), roller (2), ￠ 24mm bearing pin (3) and the solid square steel of 40*40mm (4).First with two have bearing pin (3) aperture be the Plate Welding of ￠ 24mm on the steel plate of top, form " door " shape roller mount (1), by bearing pin (3) roller (2) is installed in the roller mount (1).The four rolling seat (1) that roller (2) will be housed again is welded on respectively end, bead front and back under air bells cap (7) both sides, and the welding position requires that pallet (6) longitudinal centre line is mirror image and is symmetrical arranged, and in one plane.The notch of roller (2) requires to cooperate relative close contact with the upper plane of square steel (4), and 2mm ~ 3mm gap can be left in the notch both sides.Last square steel (4) is welded on the upper plane centreline of double flute steel (5) on air bells cap (7) the mount pad support H shaped steel of both sides, guide rail as the Mobile hot air cover, grinding process need be passed through in upper plane, and according to plane paper size on air bells cap (7) bottom surface, both sides and the support for according to adjusting, be welded with respectively roller mount (1) and the square steel (4) of roller (2).Every section air bells cap (7) welds respectively four rolling seat (1).
Before the use, be coated with lubricating oil at square steel (4) upper face first, again roller (2) and bearing pin (3) upward stamped lubricant grease with oil gun, make its sufficient lubrication.When maintenance sintering pallet (6) and sealing chute construction, first with air bells cap (7) top warm-air pipe flange (8) mouthful disassembling bolts, connecting bolt between every section air bells cap (7) is removed, from successively will every section air bells cap (7) near air bells cap (7) beginning in lifting zone to the lifting shift of area, with driving a vehicle air bells cap (7) is moved on to full cock position when shifting the traveling crane holding position onto.After the sintering machine maintenance is finished, the recovery erection sequence of air bells cap (7) and opposite the carrying out of dismounting.Need two people can finish with only resuming work in the dismounting of air bells cap (7).If before carrying out the transformation of sintering machine low-carbon technology, then air bells cap (7) directly is welded on double flute steel (5) face, during sintering board (6) vehicle overhauling, after first all pipelines of air bells cap (7) top being removed, again air bells cap (7) welding position, bottom is cut open.
