AI Technical Summary

Technical Problem

The existing excavators rely on the operator's operating level during the composite foundation base leveling process, which makes it difficult to control the leveling depth and low efficiency.

Method used

A base surface leveling and positioning device suitable for composite foundations is designed, which includes a support plate and a support frame. The distance between the support frame and the base surface is adjusted by a height adjustment mechanism. The positioning frame is plugged in and cooperated with the bucket teeth to achieve leveling by moving the bucket along the length direction of the support frame.

Benefits of technology

It reduces the difficulty of leveling construction, improves leveling efficiency, and ensures the accuracy and consistency of base surface leveling.

Abstract

The present invention discloses a positioning device and a method for leveling a base surface adapted for composite foundations, and belongs to the technical field of composite foundation construction. The positioning device includes a pair of support plates in contact with the base surface, a support frame is provided above the support plates, the support frame includes a height adjustment mechanism for adjusting the height of the support frame and the base surface, a plug-in positioning frame is clamped between the pair of support frames, and the plug-in positioning frame and the shovel teeth of the bucket form a plug-in or separate fit. The height of the support frame and the base surface is adjusted by the height adjustment mechanism, and the excavator is started so that the shovel teeth of the bucket extend into the plug-in positioning frame, and the shovel teeth are plugged into the base surface below. The bucket drags the plug-in positioning frame back and forth along the length direction of the support frame to implement leveling of the base surface. The leveling and positioning device only requires the excavator operator to match the bucket with the plug-in positioning frame to achieve accurate leveling of the base surface, thereby reducing the difficulty of leveling construction and improving leveling efficiency.
