Abstract

The invention relates to a milling head adjustment frame for a tunnel excavator, comprising a cutter head frame (1), at least one adjustment box (2) is connected to the cutter head frame (1) through guide rails (3), each The adjustment boxes (2) are all driven to move on the guide rail (3) by at least one transverse transmission device (4), and a rotating motor (8) is also connected in each adjustment box (2), and the rotating motor (8) rotates and connects to the rotating arm (10), at least one cutter head driving device (11) is connected to each rotary arm (10), and each cutter head driving device (11) drives and connects one milling head (12). The invention has the advantages of simple structure, low cost, large excavation area, high efficiency, convenient excavation of the platform, high excavation speed, suitable for use in various tunnels, and suitable for popularization and application.

Description

technical field [0001] The invention relates to a tunnel excavation device, in particular to a milling head adjusting frame for a tunnel excavation machine. Background technique [0002] A tunnel is a building built underground, underwater or in a mountain, laying railways or building roads for motor vehicles to pass. 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 slopes, it is called a mountain tunnel to pass under a mountain or hill; to pass under a river or a strait, it is called an underwater tunnel; to meet the needs of railways passing through big cities, it is called an underwater tunnel. The underground passages are called urban tunnels. [0003] Tunnel excavation methods are divided into open-cut method and under-cut method. The open-cut method is mostly used for shallow buried tunnels or urban railway tunnels, while the under-cut method is...
