Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing and conveying technology, and more specifically, relates to a pushing mechanism for conveying 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 suffer from several drawbacks. Traditional steel pipe conveying and pushing mechanisms often employ roller conveyors in conjunction with manual labor or simple pushing devices. Furthermore, these mechanisms are often simple in structure and have limited functionality. For example: 1. While existing mechanisms can move steel pipes for processing into other parts, their inability to precisely position them leads to deviations during the pushing process, affecting processing accuracy; 2. Relying on manual intervention or segmented control, existing mechanisms cannot achieve automatic pipe pushing, and the mechanism cannot reset after pushing, impacting overall production line efficiency; 3. Some pushing mechanisms have unreasonable structural designs, making installation and maintenance inconvenient, especially in confined or high-level spaces, resulting in significant maintenance difficulties.

Above the conveyor roller 20 are a frame 80 and a body 90. Each support rail 70 has an outward-facing and concave groove 100 on the side near the body 90. A transition plate 110 is connected inside the groove 100. The bottom end of the frame 80 is connected to the transition plate 110. A first mounting box 120 is connected to the top of the frame 80.

[0030] A pushing mechanism for conveying steel pipes includes a support frame 10. A plurality of conveying rollers 20 are evenly spaced at the top of the support frame 10. The two ends of each conveying roller 20 are connected to both sides of the top of the support frame 10 via mounting bases 30. A plurality of servo motors 40 and a base 50 are provided on one side of the support frame 10. The top of the base 50 is connected to the servo motors 40. The driving end of each servo motor 40 is connected to one end of its corresponding conveying roller 20. A plurality of support columns 60 are spaced apart at the top of the support frame 10. Support rails 70 are connected to both sides of the top of each support column 60. The conveying rollers 20... The vehicle is equipped with a frame 80 and a body 90 above it. Each support rail 70 has an outward-facing and concave groove 100 on the side near the body 90. An adapter plate 110 is connected inside the groove 100. The bottom end of the frame 80 is connected to the adapter plate 110. A first mounting box 120 is connected to the top of the frame 80. A drive assembly 130 is connected to the first mounting box 120. The bottom end of the drive assembly 130 is connected to the body 90, which drives the body 90 to lift or lower. The bottom end of the body 90 has a downward-facing and concave groove 140 in the middle. The bottom end of the body 90 has two sides... The cavity contains a pusher mechanism 150 connected to the vehicle body 90. The pusher mechanism 150 includes a pusher body 1501, a pusher plate 1502, and a first hydraulic cylinder 1503. Slide rails 160 are connected to both sides of the top of the pusher body 1501. A slider 170 matching the slide rails 160 is provided on the inner wall of the groove 140. The pusher body 1501 is slidably connected to the vehicle body 90. The first hydraulic cylinder 1503 is connected inside the cavity. The drive end of the first hydraulic cylinder 1503 is connected to the pusher plate 1502, and the front end of the pusher body 1501 is connected to the pusher plate 1502. When it is necessary to adjust the steel pipe... During processing, the drive assembly 130 drives the vehicle body 90 to lift, which in turn drives the pusher mechanism 150 to lift. Under the action of the conveyor roller 20, the steel pipe moves to the feeding end of the next station. When the steel pipe has completely passed under the pusher mechanism 150, the drive assembly 130 drives the vehicle body 90 to fall, which in turn drives the pusher mechanism 150 to fall. The first hydraulic cylinder 1503 drives the pusher 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. After the processing is completed, the first hydraulic cylinder 1503 drives the pusher plate 1502 to reset.

[0033] A buffer pad 200 is provided between the second mounting plate 190 and the push plate 1502 to absorb the impact and collision between the steel pipe and the push plate 1502, thereby extending the service life of the equipment.

[0034] A fixing plate 210 is connected to the side of the vehicle body 90 near the push plate 1502. A collision block 220 is connected to the side of the fixing plate 210 near the push plate 1502. The collision block 220 is used to prevent the pusher body 1501 from moving and colliding with the vehicle frame 80 when the steel pipe collides with the push plate 1502.

[0035] Both the buffer pad 200 and the anti-collision block 220 are made of polyurethane, rubber or silicone.
