Embodiment Construction

[0022] In order to make the present invention clearer, the device will be described in detail below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0023] Such as figure 1 with figure 2 As shown, the present invention provides a digging device for tunnel excavators, including a vehicle frame 1 composed of a base 1a and a housing 1b, the base 1a is a rectangular parallelepiped annular plate, and the housing 1b is a U-shaped structure , the U-shaped mouth of the housing 1b is correspondingly matched with the base 1a.

[0024] The longitudinal support 3 is connected to the longitudinal support 3 through four lifting devices 2 in the housing 1b, and the four lifting devices 2 are symmetrically arranged on both sides of the housing 1b respectively. The longitudinal support 3 is a square cylindrical structure. A support frame 3a is provided...

Abstract

The invention relates to a soil planing device for a tunnel underground excavation machine. The soil planing device comprises a frame (1) formed by a base (1a) and a shell (1b). A longitudinal support (3) is connected in the shell (1b) through a set of lifting devices (2). The front side of the longitudinal support (3) is connected with a transverse support (9). At least one adjusting device (13) is connected in the transverse support (9), each adjusting device (13) is rotationally connected with a rotary arm (14), each rotary arm (14) is at least connected with a tool bit driving device (15), and each tool bit driving device (15) is in driving connection with a mill-planing head (16). The soil planing device has the advantages that the structure is simple, high safety is achieved, upper-layer excavation and lower-layer excavation can be carried out, soil digging within a full-section range of a tunnel is achieved, full-mechanical work of underground excavation tunnel construction is achieved, the work speed is high, the application range is wide, and the device is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to a tunnel concealed excavation device, in particular to a digging device 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 bu...
