Problems solved by technology

Due to the narrow structural space inside the shield tunneling machine, it brings certain difficulties to the installation of the advanced drilling machine
In some shield tunneling machines, the drilling rig is installed on the assembly head of the segment assembly machine, which often causes damage to the assembly head of the segment assembly machine, resulting in greater losses

Abstract

A multi-degree-of-freedom switching device for an advance drilling machine of a shield heading machine comprises an advance drilling machine installation part, an advancing beam assembly, a joist, a bracket, a switching frame, a bottom bracket and a drilling machine port. The advance drilling machine installation part is connected with the advancing beam assembly. The joist is located below the advancing beam assembly and is in sliding connection with the advancing beam assembly. The middle portion of the bracket is hinged to the switching frame. The switching frame is hinged to the bottom bracket, and a pitching oil cylinder is arranged between the tail portion of the bracket and the bottom bracket. The drilling machine port is in rotating connection with the bottom bracket. The drilling machine port is arranged at the position which forms a 180-degree angle with the head portion of a segment erector so that the advance drilling machine can be installed on a moving ring beam of the segment erector and the advance drilling machine can drill slanting holes on the periphery of the shield heading machine whether the shield heading machine is at a linear heading position or curved heading position. The multi-degree-of-freedom switching device controls each degree of freedom, and enables the advance drilling machine to take its place accurately for drilling of advance holes.

Description

technical field [0001] The invention relates to an underground tunnel shield boring machine, in particular to a drilling device in the shield boring machine, in particular to provide a reliable multi-degree-of-freedom switching device for an advanced drilling machine. Background technique [0002] In the construction of underground tunnels using shield tunneling machines, since the underground geology in front is invisible, it is necessary to install drilling rigs for advanced drilling, or to perform grouting reinforcement on the weak geology ahead. The position of the advance hole of the shield boring machine is located on the periphery of the shield casing and slopes outward from the tunnel. Due to the narrow structural space inside the shield boring machine, it brings certain difficulties to the installation of the advanced drilling machine. In some shield tunneling machines, the drilling rig is installed on the assembly head of the segment assembly machine, which often ...
