Abstract
The utility model belongs to the technical field of belt conveyor, a arc bearing roller turns over tape unit to be constructed is related to, organize the arc bearing roller including many, each is organized including a convex arc bearing roller group and a concave arc bearing roller group the arc bearing roller, protruding / concave arc bearing roller group including a plurality of protruding / concave arc bearing roller and protruding / concave arc bearing roller axle, a plurality of protruding / the concave arc bearing roller constitutes the revolute pair with protruding / concave arc bearing roller axle respectively, a plurality of protruding / the outline group of concave arc bearing roller becomes a protruding / concave arc line, the convex arc line and the same centre of a circle of concave arc line, distance equal the thickness of conveyer belt, and conveyer belt return stroke limit clamp is between convex arc bearing roller group organizes with a concave arc bearing roller, the many group the arc bearing roller is arranged along the traffic direction of conveyer belt, and adjacent two pairs are twistd reverse certain contained angle each other, and many the group the arc bearing roller makes conveyer belt return stroke limit twist reverse 180 degrees. The utility model discloses make the conveyer belt move course in equilibrium in the switching process, the tensile force tends to equal, avoids stress concentration, avoids the edge fracture, increase of service life.
Description
Technical field
The utility model belongs to belt conveyer technical field, relates to a kind of belt-turning mechanism, is specifically related to a kind of Curved roller belt-turning mechanism.
Background technology
The material that load-transfer device is stained with can return along with reverse-running section, to make dirty in this process carrying roller and scatter dung along conveyer line, also can cause belt deflection, in order to prevent this from occurring, through being everlasting, reverse-running section turns over belting close to one end setting of head drum.Traditional belting that turns over uses multipair parallel roll, parallel roll is clipped in the middle load-transfer device, every a pair carrying roller makes load-transfer device reverse certain angle, and multipair carrying roller gradually transition makes conveyor belt turn-over 180 degree, and the center of twist line of load-transfer device and the line of centers of load-transfer device overlap.
This method has certain shortcoming, the route that belt edges place walks around is longer, the route of belt centerline place walking is shorter, cause load-transfer device tensile force everywhere uneven, edge often stress concentrates serious, edge easily ruptures, and institute is imperfect in this way, needs to design a kind of new scheme.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provides a kind of load-transfer device uniform Curved roller belt-turning mechanism of tensile force everywhere.
The utility model is achieved through the following technical solutions:
A kind of Curved roller belt-turning mechanism, comprise multipair Curved roller group, every a pair Curved roller group comprises a convex arc idler machining and a concave arc idler machining; Convex arc idler machining comprises multiple convex arc carrying roller and convex arc roller carrier shaft, and multiple convex arc carrying roller forms revolute pair with convex arc roller carrier shaft respectively, and the outer contour of multiple convex arc carrying roller forms a convex arc line; Concave arc idler machining comprises multiple concave arc carrying roller and concave arc roller carrier shaft, and multiple concave arc carrying roller forms revolute pair with concave arc roller carrier shaft respectively, and the outer contour of multiple concave arc carrying roller forms a concave arc line; Convex arc line and concave arc line concentric, distance equals the thickness of load-transfer device, load-transfer device backhaul limit is clipped between convex arc idler machining and a concave arc idler machining, and the operational centre line of load-transfer device the line of centers of load-transfer device of getting along well itself overlap, but are partial to convex arc line or direction, the concave arc line center of circle; Multipair Curved roller group arranges along the service direction of load-transfer device, and adjacent two to mutually reversing certain angle, and multipair Curved roller group makes load-transfer device backhaul limit turn round turnback, reaches the object of turning over band.
The beneficial effects of the utility model: load-transfer device running route in switching process can be made to trend towards equilibrium, make tensile force everywhere be tending towards equal, avoid transition of stress to concentrate, effectively avoid edge to rupture, extend the service life of load-transfer device.
