Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor rollers, in particular to a heavy-duty self-adaptive self-aligning roller. Background Art

[0002] At present, belt conveyors have been widely used in the transportation of materials in mining, metallurgy and other industries. To prevent the belt from deviating, belt conveyors are equipped with self-aligning rollers, which are composed of rollers, roller brackets and roller bases. When the belt conveyor is running, the existing self-aligning rollers are limited by the center shaft only because the deflection angle of the roller bracket and the roller base is limited only by the center shaft. When the belt conveyor is running, the rollers on both sides are subjected to different forces during deviation correction. After long-term use, the shaft of the roller bracket will gradually deflect, causing the belt to deviate again. At the same time, the roller bracket and the roller base are only supported by the center shaft. During the deviation correction process, the center shaft will be subjected to a large bending moment force. After long-term load operation, the center shaft is also easily deformed. Therefore, a heavy-duty adaptive self-aligning roller is designed to solve the above problems. Utility Model Content

The rollers are rotatably connected between the fine-tuning support plates and the mounting plates on both sides. The bottom plate is rotatably connected to the middle part of the roller base through a rotating shaft. The positions of the arc support plates on both sides of the roller base are provided with load-bearing guide wheels, and the load-bearing guide wheels are in contact with the arc support plates.
