[0058] To ensure the smooth and precise vertical movement of the roller conveyor mounting bracket 10 and to guarantee its safety, multiple auxiliary and safety devices are also installed in the mechanism:

[0059] Guiding and limiting devices: Vertically distributed guide rails 13 are installed on the columns 4, and the sliders 14 installed on the roller conveyor mounting frame 10 cooperate with the guide rails 13 (T-shaped guide rails) to provide guidance. At the same time, at least one upper limit post 11 is installed at the bottom of the top frame 7, and at least one lower limit post 12 is installed on the lowest crossbeam 6 between two adjacent columns 4 to mechanically limit the upper and lower limit positions of the roller conveyor mounting frame 10, respectively.

[0060] Fall protection and precise positioning device: A guide rack 15 distributed vertically is installed on the column 4. A guide gear 16 installed on the roller conveyor mounting frame 10 meshes with the guide rack 15 to form a fall protection mechanism.

[0061] Transmission installation: The top and bottom of the secondary transmission belt 29 are respectively installed on the column 4 via the upper lifting fixed wheel and the lower lifting fixed wheel, forming a complete lifting transmission circuit.

[0062] This invention utilizes a dual transmission system of primary and secondary transmission belts to evenly distribute the motor's power to the lifting belts on both sides via the drive wheel and transmission shaft. This effectively avoids the uneven load and torsional problems that may occur with single-point transmission, allowing for the smooth lifting and lowering of objects weighing thousands of kilograms. The automatic roller conveyor mechanism is integrated into the lifting roller conveyor mounting frame, achieving both vertical lifting and horizontal conveying functions in one unit. Once materials are in place, they can be directly conveyed through the roller conveyor, seamlessly connecting to the next process, greatly improving the automation and efficiency of material flow. A rigid frame composed of multiple columns and beams ensures overall stability under heavy loads. Safety positioning components provide mechanical hard positioning, combined with guide rails and other guiding structures, providing anti-fall functionality and greatly enhancing safety. The use of roller conveyors for material handling ensures smooth transport, avoiding damage to materials caused by traditional bucket elevators. The entire process is motor-driven, simple to operate manually, and easily integrated into automated production lines.
