Description

Technical Field

[0001] This utility model relates to the field of rotary kiln support structure technology, specifically to a roller support device. Background Technology

[0002] A rotary kiln is an industrial device used for high-temperature processing, such as calcining, roasting, or sintering various materials, including cement, lime, and metallurgical ores. The rollers of a rotary kiln are one of its key components, often called support rollers or idler rollers, responsible for supporting the kiln body and ensuring its smooth rotation. Currently, the spacing between the rollers supporting the kiln body is adjusted by bolts. However, bolt adjustment requires manual operation, which not only increases the intensity of manual labor but also easily leads to unstable bolt adjustments, affecting subsequent support of the kiln body. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a roller support device that is simple in structure, reasonably designed, and easy to use. The device uses a gear and tooth block meshing drive structure to make the left and right support wheels move synchronously, which not only makes operation simple but also allows for more precise control of the movement of the support wheels.

[0053] The pad 6-3 is fixedly installed inside the U-shaped seat 6-2, and a drive motor 6-4 is installed on the outside of the pad 6-3. The output shaft of the drive motor 6-4 passes through the pad 6-3 and is equipped with a lead screw 6-5.
