Title: SUPPORT ROLLER RACK HAVING PIVOT FRAMES AND HORIZONTAL GUIDING AND RETAINING SLITS
Abstract:
The invention relates to a support roller rack of a conveyor belt system, comprising multiple support roller racks (1) arranged in series and supporting the conveyor belt on support rollers (18, 19, 20, 30), wherein in at least one of these support roller racks (1), at least one first and one second support roller (20, 30) are arranged at a distance to one another, centrally and substantially horizontally aligned in the at least one support roller rack (1), on a pivot frame (28) which can pivot about a pivot axis (29) running in a transverse direction in relation to the longitudinal direction of the conveyor belt and which is mounted centrally in the support roller rack (1), wherein a solution is created that permits a support roller in a support roller rack to be changed with reduced effort in relation to the state of the art. This is achieved in that at least the axle ends (21) of the at least first and second support roller (20, 30) are mounted in guiding and retaining slits (11, 12, 15, 16, 26, 27) accommodating a respective axle end (21) of a support roller (18, 19, 20, 30), which slits are formed in the pivot frame (28) with the longitudinal extension thereof from the insert opening (17) oriented at least substantially in parallel to the longitudinal direction of the conveyor belt.
