Rock cracking type tunneling machine

Abstract

A rock cracking type tunneling machine comprises a crawler base, a cantilever crane system, a vibration rocker cracker, a supporting system, a slag output system, a control system and a hydraulic system, and is characterized in that the cantilever crane system comprises a pitching base installed at the front end of the crawler base through a hinge shaft and a pitching oil cylinder, a deflection base combined with the pitching base through a rotating base, a big cantilever crane combined with the deflection base through a left deflection oil cylinder, a right deflection oil cylinder and a hingepiece, a small cantilever crane installed at the front end of the big cantilever crane through a hydraulic oil cylinder and a hinge piece, the vibration rock cracker installed at the front end of thesmall cantilever crane through a hydraulic oil cylinder and a hinge piece, and a visual monitoring device arranged at the front end of the small cantilever crane, the supporting system comprises leftand telescopic type tunnel wall supporting frames located on the two sides of the middle of the crawler base, and amplitude-variable supporting legs located on the left side and the right side of therear portion of the crawler base, and the slag output system comprises a digging shovel located at the lower front end of the crawler base, and a slag conveying device located at the rear portion ofthe digging shovel and extending to the upper side of the rear portion of the crawler base from front to back.

Description

technical field [0001] The invention relates to a rock-cracking tunnel boring machine, in particular to a tunneling equipment used for non-blasting excavation of tunnels. Background technique [0002] In recent years, a large number of railways and highways have been built, and tunnels under various conditions have appeared. At the same time, the impact on production and life during the construction process has also increased day by day. As a result, the traditional tunnel construction technology (blasting method) cannot meet the special construction requirements of tunnels. In traditional construction, the blasting method is often used in the construction of tunnels with relatively hard surrounding rocks. If the surrounding environment is complex, especially when passing through urban areas, it is often close to densely populated areas with dense buildings. It is necessary to strictly control the vibration during the construction process to prevent nuisance. Impacts such as...

AI Technical Summary

Problems solved by technology

The cantilever tunnel boring machine has a lot of construction dust, low work efficiency, and uninterrupted water spraying operation; after the expansion cracking method, an excavator is used, and additional drilling equipment is required for the expansion cracking hole, and due to the lack of freedom of the boom of the excavator , the local position of the tunnel section cannot be reached; the excavator is equipped with a breaker (ripper). Since the main function of the excavator is to excavate the ground, the excavation of the plumb surface cannot be realized.
