Rapid heading machine

Abstract

The invention discloses a rapid heading machine. The rapid heading machine comprises a propelling crawler wheel (7), a heading cutter disc (2), a spiral gravel drainage device (3), a winch gravel shovel (5) and a gravel conveying belt (6), wherein the heading cutter disc (2) is a hollow conical shell body, an opening is formed in the top, and a plurality of longitudinally-arranged digging tooth claws (4) are symmetrically arranged on the side wall; and the spiral gravel drainage device (3) is coaxially installed in the conical shell body, and a heading cone (9) at the top end extends out fromthe top end of the conical shell body. In the using process, the heading cone (9) drills out a positioning hole in the rock wall, the digging tooth claws (4) on the heading cutter disc (2) gradually expand the hole, and the spiral gravel drainage device (3) further discharges the gravel crushed material out of the conical shell body of the heading cutter disc (2); and the winch gravel shovel (5) and the gravel conveying belt (6) convey the discharged gravel out, and rapid heading of the tunnel is realized. The rapid heading machine has the advantages of being strong in adaptability, fast in driving speed, high in working efficiency, safe in construction and convenient for equipment movement.

Description

technical field [0001] The present invention relates to a tunnel boring machine, in particular to a fast tunnel boring machine that can carry out closed, open, semi-open tunnel tunneling operations and full-section tunneling. It can quickly excavate rivers and ditches. Comprehensive operations such as rapid sand extraction, canal digging, and island building on the bottom of rivers and seas. Background technique [0002] Tunnelboring machine is a comprehensive equipment that uses mechanical crushing of rocks, slugging and support to implement continuous operations. According to the cutting process of the roadheader on the working face, it is divided into full-section roadheaders and partial-section roadheaders for open and semi-open tunnel excavation operations. According to different principles of rock crushing, it can be divided into rolling type (disc hob) roadheader and milling type roadheader. The traditional rolling type full-face roadheader is mostly suitable for me...

AI Technical Summary

Problems solved by technology

[0005] At present, under the harsh working conditions of strong extrusion, high wear and strong impact, the working efficiency of the full-face rock boring machine is low, and the situation of the rock formation in front is unknown. Therefore, the adaptability to various construction operations is not strong and flexible. The performance is not satisfactory, which affects the safety of the tunnel operation and the progress of the project; at the same time, the cutter head of the full-section construction is advanced in parallel with the construction section, and the traveling resistance is large, resulting in low excavation efficiency.
