AI Technical Summary
Technical Problem
During the bending process, the outer arc wall thickness of the suspension pipe is thinned, resulting in concentrated stress and prone to deformation and cracking.
Method used
A ear plate structure is designed, located between the suspension tube and the boom. The lower end of the ear plate is welded to the vertical pipe without being connected to the curved arc tube. The suspension tube is carried through the vertical pipe to avoid stress concentration.
Benefits of technology
The vertical pipe carries the suspension pipe, which avoids the wall thickness reduction and stress concentration during bending, reduces the deformation and cracking of the suspension pipe, and improves the stress of the suspension pipe.

Abstract
The utility model discloses a lug plate structure suitable for a suspension pipe, which is positioned between the suspension pipe and a suspension rod, the suspension pipe comprises a vertical pipe and an arc-shaped pipe connected with the upper end of the vertical pipe, the lug plate structure suitable for the suspension pipe comprises a lug plate, the lower end of the lug plate is welded on the vertical pipe, and the upper end of the lug plate is connected with the suspension rod; a groove is formed in the lower end of the lug plate, and the two side walls of the groove are welded to the two sides of the vertical pipe correspondingly. According to the utility model, the lug plate is welded with the vertical pipe, namely, the lug plate is not connected with the bent arc-shaped pipe, namely, the suspension pipe is borne by the vertical pipe, the wall thickness of the vertical pipe is not reduced due to bending, stress concentration is not generated at a welding seam of the vertical pipe welded with the lug plate, and the suspension pipe is not cracked due to tension; therefore, the stress condition of the suspension pipe is improved.
