Description
Technical field
The present invention relates to the online quick-restoring device of a kind of dehydrator gear ring, belong to blast furnace cinder treatment facility technical field.
Background technology
Blast furnace cinder is processed and is generally adopted shrend mode to process at present, and this just need to separate pulp water after slag water quenching, and to realize the safe and effective transport of slag, the water simultaneously separating can further recycle, and reduces the consumption of water. Conventionally way is to adopt dehydrator device, and dehydrator inside is covered with screen cloth, and outside one circle is gear ring, power set driving pinion, and pinion engages with gear wheel, thereby realizes the rotation of dehydrator, and then realizes pulp water separation.
Blast furnace is tending towards maximizing at present, and the unit interval slag of blast furnace output is many, and correspondingly dehydrator is also tending towards maximizing, dehydrator diameter ring gear 3-4 rice left and right. Because gear wheel processing is inconvenient, simultaneously also in order to reduce the manufacturing expense of overall gear ring, the general processing two halves backing ring that adopts, is evenly equipped with through hole on backing ring now, and through hole is put on bearing pin, by pinion and bearing pin engage engage for the tooth with original. When work, support the aperture of each bearing pin and bear larger effect alternate load, in process of production due to wearing and tearing and corrosion, bearing pin and pinion mate and bearing pin and cooperation place, aperture are prone to wearing and tearing, swinging appears in bearing pin, wearing and tearing aggravation, causes the not steady of dehydrator rotation, and whole transmission system is caused to serious impact, be mainly manifested in the cog-wheel coupling fracture of running part, aperture and bearing pin wearing and tearing aggravation. If integral replacing backing ring, site operation difficulty is large, and centering difficulty cannot ensure construction quality; Because site operation environment is severe, easily there is personal safety accident simultaneously; In addition, the construction period is long, also will affect blast furnace and normally produce. This is the deficiencies in the prior art parts.
Summary of the invention
For solving above technical deficiency, the invention provides the online quick-restoring device of a kind of dehydrator gear ring, can realize dehydrator gear ring fast, repair online, simple to operate and do not affect the normal operation of dehydrator.
Technical scheme of the present invention is as follows: the online quick-restoring device of a kind of dehydrator gear ring, comprise gear ring, described gear ring is made up of two semicircle backing rings, on described backing ring, be evenly equipped with through hole, the outside of described backing ring is fixed with arc, described arc is provided with connecting hole, and the position of described connecting hole is corresponding with the position of through hole on backing ring, in described connecting hole and through hole, bearing pin is installed.
Technical scheme of the present invention also comprises: one end of described bearing pin is provided with boss, and bearing pin has been threaded connection nut.
Technical scheme of the present invention also comprises: the inner side that is positioned at nut on described bearing pin is provided with spring washer.
Technical scheme of the present invention also comprises: described arc is weldingly fixed on the both sides of backing ring.
Technical scheme of the present invention also comprises: described arc is made up of wear-resisting, etch-proof stainless steel or manganese steel.
Technical scheme of the present invention also comprises: described bearing pin is connected with pinion drive, and the material of described bearing pin is identical with the material of described pinion.
The invention has the beneficial effects as follows: by the both sides at gear ring, arc is set, utilizes segmentation reparation to reduce the labour intensity while reparation, improved the remediation efficiency of gear ring, and can utilize online production interval to repair, do not affect the carrying out of production; Employing nut coordinates, and is convenient to the quick-replaceable of bearing pin.

In figure: 1, gear ring, 2, arc, 21, connecting hole, 3, bearing pin, 31, boss, 4, nut, 5, spring washer.
Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the invention will be further described.
As depicted in figs. 1 and 2, the online quick-restoring device of a kind of dehydrator gear ring of the present invention, comprise gear ring 1, gear ring is made up of two semicircle backing rings, on backing ring, be evenly equipped with through hole, the outside of backing ring is fixedly welded with arc 2, and arc 2 mainly plays the effect of fixed support bearing pin, specifically needs removable parts to make the size of arc according to scene. Arc 2 is provided with connecting hole 21, particularly, the position of connecting hole 21 is corresponding with the position of through hole on backing ring, bearing pin 3 is installed in connecting hole 21 and through hole, bearing pin is by coordinating to realize and being connected of backing ring with arc, and the fit clearance in bearing pin and arc aperture must be in Measurement Allowance.
One end of bearing pin 3 is provided with boss 31, and bearing pin 3 has been threaded connection nut 4, and the inner side that is positioned at nut 4 on bearing pin 3 is provided with spring washer 5, and spring washer and locking nut coordinate with the threaded one end of bearing pin, prevent the another axial float of bearing pin. Bearing pin carries out axial location by nut to it, because bearing pin contacts with pinion, when after the rotation of its effect of attrition dehydrator, can change by separating lower nut.
In embodiments of the invention, that arc 2 adopts is wear-resisting, the good stainless steel of anticorrosion or manganese steel, and bearing pin 3 should ensure consistent with the material of drive pinion.
When work, arc 2 is made connecting hole 21 in advance according to the space length on gear ring 1, and ensure that the clearance control of connecting hole 21 and bearing pin 3, in tolerance allowed band, is fixed by welding in backing ring both sides, then put on the bearing pin 3 lengthening with boss 31 and screw thread.
Gear ring prosthetic device of the present invention is under the prerequisite without integral replacing dehydrator gear ring, outside segmentation by dehydrator gear ring is repaired, in the situation that taking into full account rotational characteristic and work on the spot environment, be divided into arc 2, bearing pin 3 and locking nut 4, wherein arc 2 is fixedly welded on dehydrator both sides, when welding, to ensure concentric with original aperture, be connected with bearing pin 3, locking nut 4 is in the threaded side of bearing pin, as when dehydrator gear ring is because the aperture of fixed pin shaft affects due to wearing and tearing after the rotation of dehydrator, can eliminate by changing arc, if the binding site of bearing pin and gear due to effect of attrition rotate after, nut is screwed off, just can carry out quick-replaceable to bearing pin. it is loaded down with trivial details that this has just solved original integral replacing dehydrator gear ring maintenance, and the problem that easily impact is produced solves thereby realized the problem existing in original production, has ensured the stability of rotation of dehydrator.
The above, be only preferred embodiment of the present invention, not the present invention done to any pro forma restriction, allly makes within the spirit and principles in the present invention any amendment, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
