The specific embodiment
Embodiment 1
Shown in Fig. 2 and 3, a kind of chain type horizontal circulation carrying apparatus, comprise two pairs of sprocket wheels 7 that are parallel to each other and stagger and rotate synchronously, two that are separately positioned between two pairs of sprocket wheels 7 are turned round chain 5 synchronously, be respectively arranged with two suspended axles that are parallel to each other 2 on the freight house 1, freight house 1 is arranged on the chain rivet of synchronous revolution chain 5 by an end of two suspended axles 2 respectively, on the suspended axle 2 of freight house 1 both sides, be respectively arranged with double-type roller 3, the inboard that is respectively arranged with supporting rail 4, two sprocket wheels 7 below each roller 3 is respectively arranged with and suspended axle 2 ingear support teeth.
As shown in Figure 3, above-mentioned support teeth is the some groove teeth that are opened on the sheave 8, sheave 8 is arranged on the inboard of sprocket wheel 7, when reality is used, sheave 8 also can be arranged on the outside of sprocket wheel 7, perhaps be provided with sheave 8 in the inside and outside both sides of sprocket wheel 7, groove tooth on sheave 8 circumference is meshed with freight house 1 suspended axle 2 of sprocket wheel 7 sides respectively, usually, in order to reduce the setting of groove number of teeth amount on the sheave 8, the number of teeth of sprocket wheel 7 can be designed to the integral multiple t of chain number between the adjacent freight house 1, so just can t groove tooth be set at ad-hoc location.Like this, when sprocket wheel 7 drives freight houses 1 and makes circulating motion by suspended axle 2, suspended axle 2 if simultaneously with sheave 8 on the engagement of groove tooth, freight house 1 just can be when having chain to exist on bend, 2 suspended axles 2 are subjected to 4 restrictions simultaneously, can prevent that the diagonal angle from tilting.And on straight way up and down, 2 suspended axles 2 only are subjected to the traction of revolution chain 5 synchronously of two row, have only 2 stressed, this is a kind of state freely, although the friction drag of supporting rail 4 still exists, but also no longer there is the discontinuity equalization phenomenon when multiple spot draws in the background technology, significantly reduced indefinite bending stress and overbalance resistance.
As shown in Figure 3, the roller 3 run locations top, turning, last straight way two ends of above-mentioned synchronous revolution chain 5 is respectively arranged with pinch roller rail 10, between pinch roller rail 10 and the roller 3 microgap is arranged; The turning, following straight way two ends of above-mentioned synchronous revolution chain 5 is provided with curved track 11, curved track 11 and supporting rail 4 join and and roller 3 between microgap is arranged, the setting of this structure can make freight house 1 more steady during bend in turnover.For ease of observing, Fig. 3 has cutd open sprocket wheel 7, has kept sheave 8, and as can be seen, this is the device of a t=2.
Need to prove, for ease of expression directly perceived, it is coaxial with suspended axle 2 that present embodiment turns round the bearing pin of chain 5 synchronously, thereby sprocket wheel 7 is identical with the engagement object of sheave 8, in fact the two is not necessarily coaxial, in the often hinged hole of on chain and chain-plate, opening in addition of suspended axle 2, so it is strict, sprocket wheel 7 should mesh with the bearing pin of synchronous revolution chain 5, and sheave 8 just meshes with suspended axle 2, but structure is the same with transmission principle and present embodiment, as long as sheave 8 is identical with the ingear correspondence position with the engaging groove number of teeth amount of sprocket wheel 7, just can reach the identical effect of present embodiment, not draw in addition.And, for drawing for purpose of brevity, all omitted the actuating device of known technology among each figure of present embodiment, the synchronous revolution chain 5 on the straight way is represented by dotted lines, among each figure about or cooresponding up and down all be parts of the same name, repeat mark not, later similar figure is as the same.
Embodiment 2
As shown in Figure 4, a kind of chain type horizontal circulation carrying apparatus, its basic structure is substantially the same manner as Example 1, difference only is that described support teeth adopts some attached teeth 9 to be fixedly installed on a side of sprocket wheel 7, attached tooth 9 respectively with suspended axle 2 engagement of sprocket wheel 7 sides, its working process and effect and embodiment 1 are also basic identical.
