Abstract
The invention provides a novel supporting wheel device of a box opening shakeout roller. The box opening shakeout roller comprises a shakeout roller body, a circular roller guide rail and four supporting wheel device bodies. An axle of each supporting wheel device body is installed in the middle of a wheel and the two ends of each axle extend out of the two sides of the wheel and then are installed on a bracket of the corresponding supporting wheel device body. The two sides of a cavity in the middle of each wheel are provided with bearings respectively and each axle penetrates through the corresponding two bearings. The portions, outside the two bearings, of each axle are provided with jacking sleeves and nuts. Sealing covers on the outer rings of every two jacking sleeves are provided with elastic sealing rings respectively. A bracket base of each bracket is sequentially provided with a middle bracket seat and a bracket gland. Two semicircular holes between each middle bracket seat and the bracket gland form a circular hole. The two ends of each axle can be installed in the corresponding two circular holes in a matched mode. Each middle bracket seat is arranged on the corresponding bracket base. Each bracket base is installed a bracket pedestal. A sealing structure of the novel supporting wheel device is not prone to being abraded and losing the effect, repair time can be shortened, the brackets are repaired conveniently in a labor-saving mode, and the service life of the shakeout roller can be prolonged.
Description
Technical field
The present invention relates to the riding wheel apparatus of a kind of novel unpacking sand roller that uses in a kind of riding wheel apparatus, particularly casting industry.
Background technology
In foundry industry, substantially all adopt clay-bonded sand moulding.When sand mold pouring molten iron, by supercooling, solidify the knockout of will unpacking, make foundry goods separated with molding sand, molding sand is processed and be can be recycled again through regeneration.At present, widely used unpacking shakeout machinery is mainly vibrating shakeout and the large class of rolling knockout two.Vibrating shakeout exists noise large, the defect of the many and bad control of lowering the temperature of airborne dust.And that rolling knockout has noise is low, smooth running, can mist cooling and the advantage of sealing dedusting.In the vertical parting flaskless molding production technology of Denmark DISA company, use the method for rolling knockout to make foundry goods separated with molding sand.
In rolling shakeout machinery, although the rotating speed of sand roller is very slow, its volume is very large, and the diameter of sand roller reaches 3m left and right, and its length surpasses 10m.As depicted in figs. 1 and 2, sand roller 16 two ends are arranged on two support rollers 17 by cylinder round guide 15 respectively.Four support rollers form by wheel body, wheel shaft and bracket.Wheel shaft is arranged on middle its two ends of wheel body and is arranged on bracket from stretch out on wheel body both sides.In the middle of each bracket, all there is bracket hole, rolling bearing is all installed in each bracket hole, in the middle of each rolling bearing, all have dead eye.Wheel shaft two ends are arranged in dead eye and with rolling bearing rotates.Rolling bearing both sides on bracket are all provided with seal cover, and seal cover adopts labyrinth seal structure to seal.Labyrinth sealing is mechanical seal, and labyrinth seal clearance is very little, control gap between 0.1-0.15mm.Labyrinth sealing requires high to axial displacement, once move axially, be greater than clearance distance, labyrinth coordinates will be because wearing and tearing damage, and during maintenance, because rolling bearing is mounted in bracket hole, must connect bracket and together dismantle outside and could from the dead eye of bracket, take out wheel shaft replacing seal.Same bracket is difficult to accurately put in place when together dismantling and installing behind outside again, and the change in location of bracket can cause sand roller axial displacement, more fragile like this labyrinth seal.
Summary of the invention
The object of the invention is to provide according to the defect of above-mentioned sand roller riding wheel apparatus a kind of riding wheel apparatus of novel unpacking sand roller.The hermetically-sealed construction of this riding wheel apparatus is not easy to wear and lost efficacy.This riding wheel apparatus can keep bracket installation site constant, needn't movable support bracket during maintenance, and convenient and strength-saving in the time of reducing maintenance time and maintaining bracket.Can extend the service life of sand roller.
Technical scheme of the present invention is: a kind of riding wheel apparatus of novel unpacking sand roller.This sand roller cylindrical shell is arranged on four riding wheel apparatus by cylinder round guide.Each riding wheel apparatus forms by wheel body, wheel shaft and bracket.Wheel shaft is arranged on middle its two ends of wheel body and is arranged on bracket from stretch out on wheel body both sides, and bracket base is contained on pallet base.Be characterized in: bearing is all equipped with on the both sides at wheel body middle cavity, and wheel shaft is installed in two bearings.In two bearings outer axle, top cover is housed, in two top cover outer axle, is all installed with nut.On two top cover outer rings, all by screw a, seal cover is installed.In space between two seal covers and two top covers, elastic seal ring is all housed.Seat in bracket is all housed above the bracket base of each bracket, and in bracket, seat bottom has screw slots, and screw c is arranged on seat in bracket on bracket base by screw slots.There is the bracket base boss raising up at bracket base two ends, and two screw d are positioned at seat in bracket on bracket base by the bracket base boss on both sides.In bracket, seat semi-circular hole in bracket is arranged at seat top, in bracket, seat top is provided with frame gland by screw b, frame gland semi-circular hole is arranged at frame gland bottom, and in bracket, seat and two semi-circular hole of frame gland form a circular port, and wheel shaft two ends can coordinate and are arranged in two circular ports.
1, it is constant that the present invention can keep the installation site of bracket on basis, needn't connect bracket and together dismantle during maintenance.As long as take off bracket upper semi-circle gland, just can take off support roller wheel body, when maintenance completes when wheel body is loaded onto.
2, sealing gland and top cover external diameter are Elastic Contact, do not produce mechanical wear, and hermetically-sealed construction is not fragile like this.After a repack with grease, because drum rotation speed is very slow, can normally use more than 2 years.
3,, due to bearing not being installed in bracket, during maintenance, do not need all to dismantle simultaneously yet.As long as take off frame gland during maintenance with regard to replaceable support roller, make minimizing maintenance time and easy to operate.
Advantage of the present invention has been to provide a kind of riding wheel apparatus of novel unpacking sand roller.The hermetically-sealed construction of this riding wheel apparatus is not easy to wear and lost efficacy.This riding wheel apparatus can keep bracket installation site constant, needn't movable support bracket during maintenance, and convenient and strength-saving in the time of reducing maintenance time and maintaining bracket.Can extend the service life of sand roller.
