Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of steel pipe transfer equipment, and more specifically, relates to a limiting mechanism used in the process of steel pipe transfer. Background Technology
[0002] In the production or processing of steel pipes, it is usually necessary to move the steel pipes from one station to the next. Traditional transfer methods often use roller conveyors or chain drives. However, during high-speed or long-distance transfer, the steel pipes are prone to positional shifts, tilting, or even falling off due to inertia, center of gravity shift, or external interference. This can cause them to collide with the equipment at the next station, making it impossible to align them precisely and thus affecting the quality and efficiency of subsequent processing.
[0003] Existing technologies, although some employ fixed baffles or manually adjustable limit devices, have poor adaptability, cannot dynamically adjust according to the diameter of the steel pipe or the conveying speed, and are prone to scratching the surface of the steel pipe. In addition, existing equipment has a complex structure, high cost, and is difficult to maintain. Furthermore, it often requires manual intervention for adjustment, making operation difficult, inconvenient, time-consuming, and labor-intensive, thus affecting processing efficiency.
