AI Technical Summary

Technical Problem

Existing pit protection devices for aerial work platforms suffer from insufficient flexibility and stability, making them prone to tipping over, especially when traveling on uneven ground. Furthermore, their fixed structure affects the vehicle's mobility.

Method used

It adopts two sets of symmetrically arranged pothole protection components. The drive arm and connecting arm are driven by hydraulic cylinders to switch the pothole guard plate between vertical and horizontal states. The hydraulic cylinder actively extends and retracts to achieve stable support and flexible retraction of the pothole guard plate. It is equipped with sensors to detect the status.

Benefits of technology

It achieves a balance between stability and flexibility when moving on uneven ground, ensuring stable support when potholes are present, thus improving the safety and usability of the aerial work platform.

Abstract

This utility model relates to the field of engineering machinery technology and discloses an active pothole protection mechanism for aerial work platforms. It includes two sets of pothole protection components symmetrically arranged on both sides of the frame. Each pothole protection component includes a pothole guard plate and a power component that actively drives the pothole guard plate to rotate in both vertical and horizontal states. One end of the pothole guard plate is rotatably connected to a first connecting plate on the frame, and the other end is rotatably connected to a second connecting plate on the frame. The power component includes a drive arm, a hydraulic cylinder, and a connecting arm. The middle part of the drive arm is rotatably connected to the first connecting plate, the upper end of the connecting arm is hinged to the lower end of the drive arm, and the lower end of the connecting arm is hinged to the pothole guard plate. One end of the hydraulic cylinder is rotatably connected to the first connecting plate via a rotating seat, and the other end of the hydraulic cylinder is hinged to the upper end of the drive arm. This utility model offers the advantages of stable support and flexible use.
