Patent ID: 8360233

Claim:
Adjustment device for the adjustment of belts of belt conveyors, comprising a roller that is rotatable around a first axis (CR) and mounted in a cradle, which in turn is turnably mounted in a supporting stand, and, by a force generator, tiltable in relation to the stand around a second axis (CT) extending perpendicularly to the first axis (CR), wherein the adjustment device comprises a transmission actuator co-operating with the force generator, which, when the force generator generates a force having a principal first force component of a first direction, transforms into a force having a second principal force component of a second direction, which guarantees tilting of the cradle and thereby also the roller in relation to the stand, the transmission actuator being built-in into a space between the roller and a base part of the stand, the transmission actuator consisting of a carriage movable to and fro along a slide, which carriage comprises an underside and an upperside having two guide elements, which are each inclined at an acute angle (α) to the underside and which guide elements slope in different directions in relation to the underside and along which guide elements travelling members connected with the cradle and spaced apart laterally from the second axis (CT) are movable to and fro, and that the carriage is rectilinearly movable along said slide in order to—depending on the direction of motion—either raise or lower the travelling members and thereby turn or tilt the cradle in either direction around said second axis (CT).
