Beschreibung
Zusammenfassung:	The invention discloses an intelligent protective excavating trolley, comprising an excavating trolley body and a temporary supporting body. The temporary supporting body comprises a steel moulding plate and hydraulic jacks A. The steel moulding plate comprises multiple pieces of arc-shaped square steel and reinforced meshes. The multiple pieces of arc-shaped square steel are attached closely to the surrounding rock surface of a primary support line of a tunnel, and the hydraulic jacks A are correspondingly arranged on the left side and the right side of each piece of arc-shaped square steel.The reinforced meshes are hung between the pieces of arc-shaped square steel, and the bending arc angle of the reinforced meshes is consistent with that of the arc-shaped square steel. The multiple reinforced meshes are arranged, and every two adjacent reinforced meshes are connected with each other in an overlapping mode. The tops of the hydraulic jacks A are rotatably connected with the arc-shaped square steel through r
