Abstract

A walking mechanism is movably arranged on a main beam of the steel arch assembly splicing system, a supporting frame is arranged on the walking mechanism in a linkage mode, a rotary splicing ring is arranged on the supporting frame in the circumferential direction of the inner wall of a tunnel, and a rotary driving device is arranged on the inner side of the rotary splicing ring; a conveying device for conveying all parts of the steel arch frame assembly is arranged below the rotary assembling ring, an assembling gripper is arranged on the rotary assembling ring in a linkage mode, a pre-tightening device is arranged on the supporting frame in a linkage mode, and a fastening device is arranged on the rotary assembling ring in a linkage mode. The steel arch assembly splicing system is high in operation precision and construction efficiency, and the labor intensity and the safety risk of workers can be correspondingly reduced. The invention further discloses a control method for the steel arch assembly splicing system and tunneling equipment applying the steel arch assembly splicing system.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for tunnel excavation, in particular to a steel arch assembly assembly system. The invention also relates to a control method for the steel arch assembly assembly system and tunnel boring equipment using the steel arch assembly assembly system. Background technique [0002] The full-section tunnel boring machine is a large-scale tunnel construction equipment integrating mechanical, electrical, hydraulic, light, gas and other systems. With the advantages of high comprehensive benefits, the application in China's railway, hydropower, transportation, mining, municipal and other tunnel projects has grown rapidly. [0003] As an important part of the full-face tunnel boring machine, the steel arch assembly assembly system plays the role of initial support for the surrounding rock during excavation, realizing the assembly of each section of the steel arch assembly into a ring and supportin...
