Toothed chain type method and apparatus for cutting stone

Abstract

The invention discloses a toothed chain stone cutting machine, which consists of a drill, a toothed chain saw and an in-depth saw. The drill is a machine for vertically feeding into rocks through rotation; the toothed chain saw is a machine for expanding based on holes made by the drill; the in-depth saw is a machine for expanding and cutting five rock edges of upper, down, left, right and inside according to the cruciform slot made by the toothed chain saw, which is applicable to both the excavation of mining marble, granite and other stones and the cutting and excavation of road, railway and rock tunnels under river and sea without damaging the working surface and producing any vibration to the mountain or tunnel of the working surface, thus ensuring the construction safety.

Description

technical field [0001] The invention relates to engineering mechanical equipment, in particular to a cutting and digging method and mechanical equipment for mining marble, granite and other stone materials in mines and rock tunnels such as roads, railways, river bottoms, and seabeds. Background technique [0002] At present, for the mining of marble and granite in mines, rock drills or drilling rigs are generally used to drill holes, split them with expansion agents, put explosives into the rocks, and then use a gold wire saw machine to perform partial cutting. The method has the disadvantages of large stone consumption, serious environmental pollution, and it is difficult to mine shaped stones; for the excavation of rock tunnels such as roads, railways, river bottoms, and seabeds, blasting stone crushing methods are generally used at present. The work efficiency is low, and the hidden dangers of the load are serious, such as loose rocks, which are more dangerous. Although ...

AI Technical Summary

Problems solved by technology

The deficiency of this method is: the one, for precious marble, granite, not only is difficult to extract the shaped stone material, and can cause great resource waste again, the 2nd, for road, railway, river bottom, seabed etc. rock tunnel excavation Low quality, serious environmental pollution

[0003] The stone cutting and excavation methods and equipment reported in the above-mentioned public literatures have complex structures, and are limited to cutting large rocks that have been blown out of the mountain, and cannot directly cut the stones from the mountain in a neat hollow, especially in the mountains. In general, if the surrounding rocks are not destroyed, it is impossible to cut on the back of the stone, and for the construction of rock tunnels such as roads, railways, river bottoms, and seabeds that require high excavation conditions, if the back of the stone cannot be cut For cutting, digging is difficult to speed up
