Mine tunneller

Abstract

The invention relates to a mine tunneller which is characterized in that the tunneller comprises support equipment, a rotating platform and a plurality of air drills installed on the rotating platform. The rotating platform is installed at the advancing end part of the support equipment and is driven to rotate by power. A frame is fixedly arranged on the rotating platform and a plurality of slideways are arranged on the frame. Guide rails are fixedly welded on air drill shells, and the air drills are slidingly installed in the slideways of the frames through the guide rails. Each air drill is driven to lift by a hydraulic oil cylinder which is connected with a hydraulic unit. The air drills can simulate a worker to apply force to excavate upwards, slantingly or in the horizontal direction under the driving of the hydraulic oil cylinders, and the air drills can work separately or jointly according to needs. When the excavation of one blast hole is finished, the tunneller can be operated at a new position after the rotating platform rotates for a certain angle so as to finish the excavation of dense blast holes at the top of a well step by step. The mine tunneller has the characteristics of ingenious and reasonable design, simple structure and safe production process, and the occurrence of accidents can be greatly reduced.

Description

Technical field: [0001] The invention belongs to the field of mine excavation equipment, in particular to a mine tunneling machine. Background technique: [0002] Opening shafts are blind shafts that are excavated from bottom to top or obliquely upwards. The biggest advantage is that the excavated mineral materials fall naturally, which saves transportation costs in the shaft, and is especially suitable for the excavation of non-ferrous metal mines. Existing digging through the patio generally adopts the method of building an inclined ladder, and the layers are extended upwards in a Z-shaped structure, and workers need to climb to the top along the ladders to drill and other operations. Because the open well is a blind well, the air in the well is difficult to circulate. Often after the blasting, the dust and smoke in the well are billowing, and workers cannot enter to work, which affects production efficiency; moreover, the time for the smoke and dust to disperse cannot be ...

AI Technical Summary

Problems solved by technology

Because the open well is a blind well, the air in the well is difficult to circulate. Often after the blasting, the dust and smoke in the well are billowing, and workers cannot enter to work, which affects production efficiency; moreover, the time for the smoke and dust to disperse cannot be accurately predicted, which often leads to poisoning of workers. Hypoxic fainting, falling casualties and other accidents, personal safety cannot be guaranteed
