AI Technical Summary

Technical Problem

When existing leveling robots drive on uneven ground, the bumpy chassis causes the leveling accuracy to decrease and the surface flatness does not meet the standards, affecting the concrete curing quality.

Method used

The vibration suppression structure based on the damping buffer is adopted, including an x-axis offset anti-offset mechanism and a y-axis offset anti-offset mechanism. Through the cooperation of the hydraulic damping buffer and the rotating table, multiple degrees of freedom compensation can be achieved to suppress the impact of chassis vibration on the execution end.

Benefits of technology

It effectively suppresses chassis vibration, ensures that the leveling mechanism always maintains a horizontal attitude during dynamic movement, improves the accuracy and flatness of road surface leveling, and improves the quality of concrete curing.

Abstract

The invention discloses a vibration suppression structure based on a damping buffer and a leveling robot. The vibration suppression structure comprises an x-axis anti-deviation mechanism and a y-axis anti-deviation mechanism which are arranged in a double-layer mode. A dynamic compensation mechanism is formed through dynamic cooperation of a rotating table and a limiting hole, in the pitching direction, through the collaborative design that a fixed connecting shaft and a movable connecting shaft are combined with a y-axis damping buffer, y-axis pitching vibration, caused by chassis bumping, of an execution tail end is converted into linear displacement of the movable connecting shaft, and counter-acting force is dynamically adjusted through the y-axis damping buffer; the execution tail end horizontal posture is forcibly recovered; meanwhile, in the left-right direction, the symmetrically-arranged x-axis damping buffers form a couple balance structure to achieve symmetrical damping suppression of x-axis rotation, and interference of left-right vibration of the chassis to the horizontal state of the execution tail end is directly counteracted.
