Problems solved by technology

At present, trolleys are often used for construction, which are generally divided into two types: tracked and trackless. The tracked type needs to lay guide rails on the tunnel floor first, and the trolley moves on it. The trackless type is completely implemented by manpower or loaders. The tracked type The track laying of the trackless trolley takes a lot of time and affects the construction, and the trackless trolley has equipment and personal safety risks during the process of putting in place and evacuating

Abstract

The invention discloses a wheeled moving trolley used for tunnel excavation, and relates to tunnel excavation equipment. The wheeled moving trolley comprises a trolley main body, wherein the bottom of the trolley main body is provided with at least two groups of rotating wheels. The trolley is dragged to forwards and backwards walk through forward and backward movement of a loading machine. Simplicity and convenience are realized. Compared with the existing trolley, the wheeled moving trolley has the advantages that the rail laying time is saved, and the time and the cost are reduced for tunnel construction.

Description

technical field [0001] The invention relates to a tunnel excavation equipment, in particular to a wheeled mobile trolley used for tunnel excavation. Background technique [0002] Tunnel excavation adopts blasting construction, and construction such as blasthole drilling before blasting requires a bench or trolley as the construction foundation, on which construction personnel and pneumatic drills are used for construction. At present, trolleys are often used for construction, which are generally divided into two types: tracked and trackless. The tracked type needs to lay guide rails on the tunnel floor first, and the trolley moves on it. The trackless type is completely implemented by manpower or loaders. The track laying of the trackless trolley takes a lot of time and affects the construction, and the trackless trolley has equipment and personal safety risks in the process of putting in place and evacuating. Contents of the invention [0003] One object of the present i...
