Belt transporter that can automatic deviation correction
Technical field
The utility model belongs to a kind of material transport system framing member, is applicable to the transporting system for raw materials such as blast furnace sinter ore deposit and coke, is specifically related to a kind of belt transporter that can automatic deviation correction.
Background technology
Belt feeder lining wheel weight box is the take-up device in belt composition, and it provides enough tension force to belt transporter, belt transporter can normally be moved in the time starting and avoid skidding.The vertical running orbit of lining wheel weight box must keep highly consistent with belt operational centre line, otherwise the just easy sideslip of belt.Belt feeder lining wheel weight box and row frame column should, on same parallel lines, slide up and down, light freely without swipe, effectively regulate the elasticity of belt transporter.In daily production, normal appearance, due to the capable frame column distortion of belt transporter, causes lining wheel weight box to tilt, and makes belt generation deviation phenomenon.
In the time that row frame column deforms, lining wheel weight box, in heeling condition, just has certain angle between lining wheel weight box and column, makes the line of centers of lining wheel and leather belt head tail wheel not on same straight line, and belt starts sideslip.In the time that the distortion of row frame column increases, belt deviation is just more serious.If process not in time, to bring harm to production facilities: standing in the breach is harm lining wheel, in the time that lining wheel weight box tilts, belt lining wheel both sides unbalance stress, it is bad that stressed large belt will serve as a contrast wheel one side grinding very soon, in addition, in the time of belt deviation spreading, a material part of spreading is brought into lining wheel, for a long time lining wheel is rubbed, and shortened the service life of lining wheel greatly; Next is to endanger support roller and belt: belt can make the support roller of sideslip one side and the contact surface of belt increase to a direction sideslip for a long time, and friction force strengthens, and makes support roller impaired serious, has shortened the operating cycles of support roller; Lining wheel, the support roller of having ground away, will tear not in time and draw belt if change, and when serious, can cause belt to be scrapped in advance; Also likely make the joint perk of belt, belt is in operation and is likely pulled off suddenly, cause industrial accident, to blast furnace, production brings and has a strong impact on.
The repair process method of the row frame column distortion of prior art to girder steel formula generally has two kinds, cold school and hot school, and cold school is deformed bar stretching method, and hot school is flame correction method; These two kinds of methods all need to drop into a large amount of machinery, as pushing or drop into a large amount of thermals source, toast the equipment such as jack, the row frame column of distortion is resetted, although this method can be put things right once and for all, but the lining that is used in small deformation is taken turns on the capable frame column of weight box and is exhausted the people and drained the treasury a little, loses more than gain, and the reasons are as follows: the one, drop into a large amount of mechanical equipment or thermal source, make productive costs suddenly increase, unrealistic under the existing cost pressure of factory; The 2nd, repairing to proofread and correct needs a large amount of time, belt not to turn to mean that downstream production line stops production, and has reduced output.
Summary of the invention
The purpose of this utility model is exactly to overcome the defect that above-mentioned prior art exists, provide a kind of and do not need additionally to increase machinery and equipment, in the situation that not stopping production to belt transporter rectify a deviation, simple possible, cost-saving belt transporter that can automatic deviation correction.
For achieving the above object, what the utility model was designed can automatic deviation correction belt transporter, comprise two girder steel formula row frame columns, described two row frame columns inner side is respectively equipped with guidepost, the top of described two guideposts is provided with bearing base, lining wheel is installed on described bearing base, described lining wheel top is provided with lining wheel cover plate, on described lining wheel, be provided with belt, the bottom of described two guideposts is provided with weight box, described weight box is provided with weight box cover plate, the bottom surface of described weight box both sides is fixedly connected with respectively rotary corner plate, on the vertical plane of described rotary corner plate, be fixed with adjusting bolt.
Further, described rotary corner plate is provided with two vertical planes.
Again further, between the top of described two row frame columns, be connected with an angle bar or steel tank.
The utility model regulates the distance between weight box and row frame by adjusting bolt, belt lining wheel weight box is locked in a normal hunting range all the time, lining wheel weight box width centreline and belt center line (being as the criterion with bend wheel center) overlap ratio are no more than 2mm, ensure its shaft centre line level, eliminate the hidden danger of belt equipment, solve the problem of being out of shape the serious sideslip of belt producing because of row frame column, both extended the service life of belt and drive apparatus, save cost, also ensure the safe and efficient running of band conveyor, feed is unimpeded, for the direct motion high yield of blast furnace is laid a good foundation
Because adjusting bolt is adjustable, in the time of belt overhaul of the equipments and belt replacing, need only back loose a few circle adjusting bolt, lining wheel weight box just can be mentioned freely, and the maintenance of belt and replacing just can have been carried out, very convenient.
Brief description of the drawings
Fig. 1 is a kind of structural representation of belt transporter that can automatic deviation correction.
In figure, row frame column 1, guidepost 2, bearing base 3, lining wheel 4, lining wheel cover plate 5, belt 6, weight box 7, weight box cover plate 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Shown in figure can automatic deviation correction belt conveyor, comprise two girder steel formula row frame columns 1, two row frame column 1 inner sides are respectively equipped with guidepost 2, the top of two guideposts 2 is provided with bearing base 3, lining wheel 4 is installed on bearing base 3, lining wheel 4 tops are provided with lining wheel cover plate 5, on lining wheel 4, be provided with belt 6, the bottom of two guideposts 2 is provided with weight box 7, weight box 7 is provided with weight box cover plate 8, the bottom surface of weight box 7 both sides is fixedly connected with respectively rotary corner plate 9, rotary corner plate 9 is provided with on the vertical plane 9.1 of two vertical plane 9.1 rotary corner plates 9 and is fixed with adjusting bolt 10, the adjustable side of two adjusting bolts 10 arranges in opposite directions.Frame column 1 top of being expert at, is welded with an angle bar or channel-section steel 11, and the two ends of angle bar or channel-section steel 11 are connected with the top of two row frame columns 1 respectively, can stop row frame column to deform.
Regulate the distance between weight box 7 and row frame column 1 by adjusting bolt 10, weight box 7 is locked in a normal hunting range all the time, center line (being as the criterion with the bend wheel center) overlap ratio that is weight box 7 width centrelines and belt 6 is no more than 2mm, ensures that the line of centers of lining wheel 4 axles is all the time in level.The utility model is simple in structure, not needing additionally to increase machinery and equipment, do not stop production in the situation that, belt transporter is rectified a deviation, and has not only saved cost, has also ensured the safe and efficient steady running of band conveyor.
