Tunneling, anchoring and supporting all-in-one machine

Abstract

The invention provides a tunneling, anchoring and supporting all-in-one machine and belongs to the technical field of coal mining equipment. On account of the defects that existing tunneling, anchoring and supporting all-in-one machines are low in working efficiency, high in labor intensity and high in danger level, structural improvement is conducted. The tunneling, anchoring and supporting all-in-one machine structurally comprises a cantilever tunneling machine, drilling and anchoring systems and a temporary supporting mechanism. The cantilever tunneling machine comprises a body part, a cutting part located at the front end of the body part, and a caterpillar band traveling part located under the body part. The number of the drilling and anchoring systems is two, and the two drilling and anchoring systems are symmetrically arranged on the left side and the right side of the body part of the cantilever tunneling machine. Each drilling and anchoring system comprises a top anchor mechanism and a side anchor mechanism arranged front and back, and the top anchor mechanism and the side anchor mechanism of each drilling and anchoring system are fixedly installed on the body part of the cantilever tunneling machine through a longitudinal moving mechanism. Furthermore, each top anchor mechanism is installed on the corresponding longitudinal moving mechanism through a cantilever overturn mechanism. Structural improvement is conducted on the top anchor mechanisms, the side anchor mechanisms and the temporary supporting mechanism, and the application range of the tunneling, anchoring and supporting all-in-one machine is widened.

Description

technical field [0001] The invention relates to coal mine equipment, in particular to an integrated machine for digging, anchoring and protecting. Background technique [0002] The all-in-one machine for excavating, anchoring and protecting is a comprehensive equipment that integrates excavation, temporary support, and drilling and anchoring operations. question. [0003] In recent years, my country's coal industry has developed rapidly. With the increasing coal production, mining technology and mechanization have also been greatly developed. The longwall coal mining method commonly used now has basically realized the comprehensive mechanized mining consisting of hydraulic supports, scraper conveyors and shearers, with high production efficiency, low labor intensity and production safety can be guaranteed. However, in the process of roadway excavation, in addition to the improvement of the quality of the roadheader itself, the overall technological level still maintains th...

Problems solved by technology

It can be seen from this that in the entire operation cycle, only the cutting time is in the footage, which can only account for 30% of the entire working time. The rest of the time is carrying out support operations, and they are all done manually, which has the advantages of low work efficiency, Defects with high labor intensity and high risk
