Abstract

The invention relates to a cutter head frame for a tunnel digging machine. The cutter head frame (1) is connected with an adjusting device (3), wherein both the cutter head frame (1) and the adjusting device (3) are rotatably connected with a rotating arm (4), and a cutter head driving device (5) is connected onto the rotating arm (4) and is in driving connection with a mill-planing head (6); a main scraper (8) is fixedly hinged to the cutter head frame (1) through first hinge seats (7), first hydraulic cylinders (10) are hinged to the lower side of the cutter head frame (1), piston rods of the first hydraulic cylinders (10) are fixedly hinged to the main scraper (8), and the first hydraulic cylinders (10) drive the main scraper (8) to rotate in a vertical plane around the first hinge seats (7). The cutter head frame has the advantages that the cutter head frame is large in digging area and high in efficiency, so that the digging of station platforms is facilitated; dug soil can be subjected to centralized treatment, so that the removal is convenient, rapid, timesaving and laborsaving; fully-mechanized operation for tunnel digging construction is achieved, the operation speed is high, and the applicable range is wide, so that the cutter head frame is applicable to popularization and application.

Description

technical field [0001] The invention relates to a tunnel concealed excavation device, in particular to a cutter head frame for a tunnel concealed excavator. Background technique [0002] A tunnel is a building built underground, underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. In order to shorten the distance and avoid large ramps, it is called a mountain tunnel that passes under mountains or hills; in order to cross rivers or straits, it is called an underwater tunnel that passes under a river or under the sea; in order to meet the needs of railways passing through large cities, it is called a tunnel. Those that pass underground are called urban tunnels. [0003] Tunnel excavation methods are divided into open-cut method and underground excavation method. The open-cut method is mostly used in shallow...
