AI Technical Summary

Technical Problem

Existing highway excavation engineering support devices are inadequate in terms of adjustment flexibility, protection integrity, positioning reliability, and construction efficiency, making it difficult to meet the slope protection needs under complex working conditions.

Method used

The support frame structure is adopted, and the length and width of the support frame can be adjusted by the cooperation of the fixing ring, the transverse limiting groove, the motor-driven transverse tie rod and the threaded groove. The protective belt can be unfolded and stored by combining the storage box, the lifting motor and the winding motor. The positioning and fixing are carried out according to the slope and angle by using the adjusting motor and the positioning bucket.

Benefits of technology

It improves the adjustment flexibility and stability of the support device, reduces the workload of construction workers, enhances the protective integrity and positioning reliability, improves construction efficiency, and avoids safety hazards.

Abstract

This invention belongs to the technical field of road engineering. It discloses a protective device for highway construction excavation projects, including a support frame. The support frame has symmetrically arranged fixing rings on both sides of its middle end. A crossbar is fixedly connected inside each fixing ring. A transverse limiting groove is symmetrically formed inside each crossbar, and a transverse tie rod is fitted inside each transverse limiting groove. This invention uses fixing rings to install the crossbar, center block, thick vertical bar, and thin vertical bar inside the support frame. The transverse limiting groove and transverse tie rod limit one end of the center block, keeping it in the middle of the support frame during adjustment. This prevents insufficient internal support from causing instability when the support frame is expanded. The length of the support frame can be adjusted for highway excavation projects, increasing its usability. The width of the support frame can be limited during adjustment, maintaining its original shape.
