Description

Technical Field

[0001] This utility model belongs to the field of steel pipe conveying and processing technology, and more specifically, relates to a moving mechanism for pushing steel pipes. Background Technology

[0002] On a steel pipe processing production line, conveyor equipment is typically used to transfer steel pipes from one workstation to another and accurately position them for subsequent processing (such as cutting, drilling, welding, etc.). Conveying equipment significantly reduces the labor intensity of workers and greatly improves work efficiency.

[0003] However, existing technologies often employ fixed push rods or hydraulic cylinders for direct pushing during steel pipe processing. As steel pipes vary in length, the pushing mechanism often fails to accurately push them to the next workstation, leading to deviations and affecting processing accuracy. Furthermore, the pushing mechanism typically has limited conveying distance, lacks effective movement and positioning control, and existing equipment is complex, making maintenance and repair inconvenient.

A first mounting box 130 is connected to the top of the vehicle frame 80. A drive assembly 140 is connected to the first mounting box 130. The bottom end of the drive assembly 140 is connected to the vehicle body 90, which drives the vehicle body 90 to lift or lower. A pushing mechanism 150 is connected to the vehicle body 90. The pushing mechanism 150 is used to push... The steel pipe is delivered to the next workstation. A second mounting box 160 is connected to the top of the frame 80.

Under the action of the conveying roller 20, the steel pipe moves to the feeding end of the next station. When the steel pipe has completely passed under the pushing mechanism 150, the drive assembly 140 drives the carriage 90 to fall, which in turn drives the pushing mechanism 150 to fall. The first hydraulic cylinder 1503 drives the push plate 1502 to abut against the end of the steel pipe and pushes the steel pipe to move completely to the next station for processing until the processing is completed.
