Description
Technical field
The utility model relates to a kind of molten iron pourer, and is specifically, relevant with roller and metal liquid ingot casting conveyer chain.
Background technology
In the field of molten iron casting, the conveyer chain that transports ingot casting is generally the portable conveyer chain structure of roller.As shown in Figure 1, each chain link has roller 11, pin link plate 12, inner plate 13, bearing pin 14, packing ring 15 and spring cotter 16.A plurality of chain links are formed metal liquid ingot casting conveyer chain, and each chain link top has pig mold 17.Pin link plate 12 alternately is connected in twos with inner plate 13, and roller 11 is positioned between two inner plates 13 by bearing pin 14 in the junction of interior pin link plate, and is fixing by packing ring 15 and spring cotter 16 in the outside of pin link plate 12.The both ends that are positioned at conveyer chain are provided with sprocket wheel, when sprocket rotation, and the tooth mesh roller on the sprocket wheel, thus drive the motion of whole conveyer chain and turn to.Do not participate in the ingear roller by track support and rolling in orbit, so conveyer chain can transport pig mold and molten iron moves.In this structure, roller can play the supporting loading with the tooth mesh on the sprocket wheel again.Because of in real-world operation, the molten iron of fusion is housed in the pig mold of conveyer chain top, in the process of in mould, injecting molten iron and transporting molten iron, molten iron is splashed between roller both sides and the carrier bar slit easily, locate between roller and the bearing pin etc., appearance is stuck with roller, the situation that roller can not be rotated causes the damage of roller and track.Simultaneously, when clearing up molten iron, foreign material and replacing roller, need the interior pin link plate of at least two joints is pulled down and can be realized, the situation of operation and maintenance inconvenience therefore also occurred.
The CN2381417Y utility model discloses a kind of roller cantilevered metal liquid ingot casting conveyer chain, as shown in Figure 2, each chain link has roller 21, pin link plate 22, inner plate 23, major axis 24, minor axis 25, homalocephalus 26, packing ring 27, nut 28, wheel cover 29, meshing wheel 210 and spring cotter 211, above conveyer chain, has pig mold 212, pin link plate 22 alternately is connected by the homalocephalus 26 on major axis 24, the minor axis 25 in twos with inner plate 23, and have wheel cover 29 in the junction of interior pin link plate, meshing wheel 210 is arranged in the arranged outside of taking turns cover 29.The conveyer chain of this structure adopts the form that roller 21 is placed the outside of pin link plate 22,21 effects of bearing bearing load of roller, and and the gear teeth of sprocket wheel to carry out ingear be the meshing wheel 210 that wheel between inner plate 23 overlaps 29 outsides.Because roller 21 away from the pig mold on it 212, therefore can stop a part of molten iron to enter roller inside, but can not stop fully.And in the conveyer chain of this form, roller is not arranged on the junction of each pin link plate and inner plate, but adopt the mode that is provided with at interval, in this mode, major axis is a solid axis body, weight is big and can not make minor axis and major axis reach exchange, commonality difference nor utilize the mass production of minor axis.
In the above-mentioned existing molten iron pourer, when roller rolled in orbit, owing to have the gap between mandrel and the wheel body, so molten iron entered easily and makes wheel body not rotate wheel body relative to mandrel; And because wheel body and mandrel friction, wheel body needs overcome friction bigger, causes the energy consumption of conveyer chain running to increase, and reduced the service life of conveyer chain.

Owing between the wheel body and first sleeve, be provided with bearing, can greatly reduce the friction force of wheel body and mandrel; And because capping partially enclosed with between the mandrel hole inwall and first sleeve outer surface also can stop molten iron to enter roller inside fully,
Alternative plan of the present utility model, it is a plurality of further being limited to the bearing that is provided with in the described mandrel hole on the basis of first scheme, is provided with second sleeve between per two bearings.
Because be provided with a plurality of bearings and sleeve be set between bearing, so can further improve the smoothness that roller rolls.
Third party's case of the present utility model, it is a plurality of further being limited to the bearing that is provided with in the described mandrel hole on the basis of first scheme, and described mandrel hole inwall is provided with annular lip, and annular lip is between per two bearings.
Because do not need to make in addition second sleeve, so on the basis of reducing manufacturing cost and cost of installation, this programme can reach the technique effect identical with alternative plan.
Cubic case of the present utility model provides a kind of metal liquid ingot casting conveyer chain, is engaged from beginning to end by a plurality of chain links and forms; Each chain link is symmetrical structure, has two groups of inner plate assemblies, pin link plate, mandrel and rollers, is arranged at intervals with major axis therebetween; The inner plate assembly has inner plate, second sleeve and is sleeved on roller on second sleeve; Described mandrel passes second sleeve pin link plate is linked to each other with the inner plate assembly, and stretches out to the chain link outside; On described inner plate and pin link plate, be provided with the pig mold support; Described roller has wheel body, and the wheel body middle part axially has the mandrel hole along it; Be provided with first sleeve in described mandrel hole, be provided with bearing between the mandrel hole and first sleeve, first jacket casing is connected on an end of described mandrel, thereby roller is connected with mandrel; Also be provided with capping at both ends, described mandrel hole, capping is by bolted connection partially enclosed to wheel body and with between the mandrel hole inwall and first sleeve outer surface; Described major axis is a sleeve pipe, and its two ends connect the other end away from roller of described mandrel respectively.
The friction force that the metal liquid ingot casting conveyer chain that this programme provides can greatly reduce wheel body and mandrel when cutting down the consumption of energy also by mandrel and mandrel with being connected of telescopic major axis this mode reduce axis body weight, minor axis and major axis can be exchanged, improve the commonality of product component and the mass production of minor axis, also make the productive costs of equipment reduce and prolonged the service life of conveyer chain.
The 6th scheme on the basis of above-mentioned the 5th scheme, is set up a way roller inclination and is tiltedly extended to cover the backplate of roller on the pig mold support.This backplate can be with coverings such as roller, mandrel, pin link plate and inner plate assemblies, and actv. has stoped being splashed into of molten iron.
