How to design the tilting mechanism of third-generation lean pipe?

The following is a summary of the design points for the third-generation lean pipe tilting mechanism:

1、 Core structure design
Pipe selection
Adopting aluminum alloy lean pipes with a diameter of 28mm or 43mm (wall thickness 1.7-2.3mm), anti-corrosion and rust prevention are achieved through anodizing treatment, which is lightweight and has strong load-bearing capacity.
Implementation method of tilting mechanism
Hinge connection: Use aluminum alloy special 90 ° hinge joints to achieve adjustable angles (0-45 °), paired with a rotating component with locking function to fix the tilt position.
Pneumatic/counterweight control: optional cylinder or tension balancer (such as spring mechanism) for automatic angle adjustment, suitable for feeding and unloading scenarios.
2、 Selection of key components
Connectors: Priority should be given to using die cast aluminum cross joints and T-joints to ensure structural rigidity.
Base reinforcement: Add a triangular support frame or counterweight foot cup at the bottom to prevent tipping when tilting.
Anti slip treatment: Install rubber pads or smooth strips on the contact surface to prevent material sliding.
3、 Design considerations
Load verification: Calculate the torque based on the tilt angle. If the load capacity is greater than 50kg, 43mm diameter pipes or reinforced ribs should be selected.
Modular expansion: Reserve standard interfaces for easy installation of sensors or conveyor belts in the future.
Human Machine Engineering: The recommended inclination angle is 15 ° -30 °, which meets the requirements of operational comfort.
Application case: The feeding mechanism of a certain production line is built with 28mm aluminum tubes, which can be tilted at 30 ° through hinge joints. With the help of a tension balancer, the material box can automatically slide down. The measured single point bearing capacity is 40kg.
