Abstract

The invention discloses a trolley for tunnel full-face excavation, drilling and steel arch installation. The trolley for tunnel full-face excavation, drilling and steel arch installation comprises shifting rollers, telescopic cross beams, a bottom lifting support beam, a top lifting support beam, a drilling system, support hydraulic telescopic arms, hydraulic rods, propped hydraulic telescopic arms, telescopic lazy arms, a steel arch small trolley and a hydraulic system. Compared with the prior art, the trolley for tunnel full-face excavation, drilling and steel arch installation, disclosed bythe invention, has the advantages that 1) drilling at any angle in the longitudinal and radial directions of a tunnel can be realized; 2) the positions of the bottom lifting support beam and the toplifting support beam can be adjusted, so that different tunnel construction requirements can be adapted to; 3) the moving small trolley is additionally installed, so that the hoisting, adjustment andfixation of a steel arch can be realized; 4) the hydraulic system drives and controls hydraulic parts of the whole device, and ensures stable control, concentrated control and convenient operation; and 5) a plurality of types of work can coordinate and work simultaneously, and the construction efficiency is ensured.

Description

technical field [0001] The invention relates to a large-scale electromechanical-hydraulic trolley device which can be generally used for tunnel excavation, rock drilling, drilling, anchor rod drilling and steel arch installation. The device belongs to the field of special equipment for tunnel excavation, blasting, rock drilling and preliminary support construction. Background technique [0002] The trolley is the general term used for the construction of a certain structure of the tunnel. The tunnel excavation is firstly carried out by drilling and blasting the rock on the face of the tunnel, and then drilling the anchor rods to install the steel arch shotcrete pre-support after the muck is excavated. At present, manual wind guns or multi-arm chisels (2-3 arms) are often used for rock drilling, and rock platforms must be positioned and fixed multiple times; steel arches are mostly installed with simple benches, and the manual installation speed is relatively slow. A large-sc...
