AI Technical Summary
Technical Problem
The buffer pads of existing power aerial working elevators are single in form and will easily fall off shortly after use, resulting in uneven bottom of the elevator and inability to contact the workbench in synchronization, posing safety hazards.
Method used
A buffer base is designed, adopting a downwardly protruding U-shaped structure and fitting bolts. The buffer pad is embedded in the bottom of the fixed square tube, and is fixedly connected by bolts to reduce the number of connectors, enhance structural strength, and avoid falling off.
Benefits of technology
It effectively improves the reliability and safety factor of the power aerial operation lifting device, reduces deformation risk, and extends service life.

Abstract
The present invention discloses a buffer base and an electric aerial work lifting device, comprising a mounting plate, a U-shaped structure is arranged on the mounting plate, a buffer pad is arranged at the bottom of the U-shaped structure, a connecting portion is arranged at the top of the buffer pad, fixed square tubes are arranged on both sides of the U-shaped structure, the fixed square tube cooperates with the U-shaped structure to form a slot structure adapted to the buffer pad, the buffer pad protrudes from the bottom of the fixed square tube, and the fixed square tube, the U-shaped structure and the connecting portion are fixedly connected by a first bolt assembly. The present invention adopts a novel structure and assembly method, which greatly reduces the number of connectors in the entire buffer base, facilitates production and assembly, and ensures the overall structural strength, and is not prone to deformation. In particular, the buffer pad is fixed by an embedded matching bolt fixation method to avoid falling off, which greatly improves the reliability of the entire electric aerial work lifting device and improves the safety factor.
