Description
Technical Field
The utility model relates to a transportation is equipped, specifically is applied to a chain of conveyer belt type dumper and complex conveyer belt with it.
Background
The utility model discloses a people has disclosed "a bulk cargo bicycle tipper without bottom plate" with publication number CN108944617A, as shown in fig. 1, adopt heterotypic chain 1 outer support connection end to end's conveyer belt 2, sprocket 3 pulls heterotypic chain 1 and then drives conveyer belt 2 and form closed loop continuous motion transported substance material. When the special-shaped chain 1 winds around the chain wheel 3, the track of the special-shaped chain 1 is not a standard semicircle but a half regular polygon, and the conveying belt 2 can also fit the track of the half regular polygon to form a half regular polygon with an approximate shape and larger side length. Since the conveyor belt 2 is fixed on the profiled chain 1 in sections, and the distance between two pins of the profiled chain 1 is rigid as the distance between a and b in fig. 1, when the profiled chain 1 drives the conveyor belt 2 to the right of the sprocket 3, the distance between the points a1 and b1 of the inner surface of the conveyor belt 2 corresponding to the two pins of each profiled chain is necessarily greater than the distance between a and b, and the distance between the points a2 and b2 of the outer surface of the conveyor belt 2 corresponding to the two pins of each profiled chain is necessarily greater than the distance between the inner surfaces a1 and b2 and is further greater than the distance between a and b, that is, the conveyor belt 2 must be properly stretched to turn over 180 degrees around the sprocket along with the chain, but because the conveyor belt 2 needs to carry tens of tons of goods, it needs great tensile strength, so that tensile deformation is not easy to occur, and serious wear and seizing phenomena of the chain and sprocket are caused, so that the operation is limited. In addition, even if the conveyer belt 2 can be stretched and deformed, the conveyer belt 2 is rapidly loosened due to the irreversible stretching and deformation, and the conveyer belt is rapidly loosened again after being tensioned, so that a vicious circle is formed, and the normal operation cannot be realized.
SUMMERY OF THE UTILITY MODEL
For overcoming the above-mentioned technical problem of prior art, the utility model discloses a new construction of chain and complex conveyer belt with it is in order to stop it, and the technical scheme who takes is:
this kind of chain and complex conveyer belt with it, including two end to end chains that wait the link number, the chain includes inner plate, outer plate, round pin axle and roller, is different with prior art: the rollers are matched with a guide rail fixedly arranged on the frame in a rolling way, the inner sides of the two chains opposite to the inner sides of the two outer chain plates are fixedly connected with two ends of a connecting plate respectively, and the connecting plate is fixedly connected with a conveying belt in an end-to-end way; the central axis of the pin shaft is positioned on the central plane at one half of the inner surface and the outer surface of the conveying belt; or, the central axis is located inside or outside the central plane, but the vertical distance between the central axis and the central plane is less than 2 mm.
When the axis of round pin axle is located when the central plane of conveyer belt internal surface and surface half department, the conveyer belt is in the state of the ideal along with the 180 degrees in-process of chain around the sprocket upset, and can not stretched and produce deformation, and the upper surface department of conveyer belt can only produce slight reversible tensile deformation, and the lower surface can only produce slight reversible compression deformation, and the effort that produces tensile deformation and compression deformation offsets each other, can not cause the card of chain and sprocket not do not, reduces wearing and tearing, and the conveyer belt long-time operation can not become the pine yet.
However, since the manufacturing process is not ideal, it is acceptable that the center axis is located inside or outside the center plane but at a vertical distance of less than 2mm, the chain and sprocket are slightly jammed and worn, and the belt loosening period is extended.
The other scheme is that the chain further comprises additional chain plates, the additional chain plates are arranged on the outer sides of the outer chain plates, and the connecting plates are fixedly connected to the additional chain plates but not to the outer chain plates. The pin shaft of course needs to be correspondingly lengthened. In this way, when a problem occurs in a link or a link plate of the chain, the damaged part can be replaced individually without replacing the whole chain.
In another scheme, two ends of the connecting plate extend upwards to form plate lugs, pin holes corresponding to the pin holes in the outer chain plates are formed in the plate lugs, and the connecting plate is inserted into the pin shafts through the pin holes in the plate lugs. The connecting plate with the plate lugs can be formed by punching, so that not only are additional chain plates not needed, but also the additional chain plates are not needed to be welded and fixedly connected with the two ends of the connecting plate one by one, and the production efficiency is improved. Meanwhile, a certain chain link or a certain connecting plate can be independently replaced.
Further, the cross section of the connecting plate is in the shape of a groove with an inward opening. This can greatly increase the bending strength of the connecting plate.
Furthermore, more than one bearing or universal ball is uniformly arranged below the connecting plate; the rotating shaft direction of the bearing is consistent with the length direction of the connecting plate, and the bearing or the universal ball is matched with a track fixedly arranged on the frame in a rolling manner. The supporting force of the chain roller to the conveying belt can be shared, so that the conveying belt can bear more goods, and the rotation is more labor-saving.
The utility model discloses still disclose the dumper that contains any above-mentioned chain and complex conveyer belt with it.
