Problems solved by technology

[0004] At present, the cantilever roadheader is mostly used in coal mine roadway excavation. The cutting range is not the whole section, and the cutting is carried out with picks. For the hard coal rock, the excavation efficiency is low; and most of the excavation and support operations are independent operations. The support work is mostly carried out by bolter drilling rigs, which have strict requirements on the empty top distance, not only the support efficiency is low, but also the danger of the operators will be increased in the case of poor geological conditions; more importantly, the coal mine roadway contains Coal dust and gas, because the commonly used roadheader includes an electrical system, if it is used in coal mine roadway operations, it is inevitable that catastrophic accidents will occur due to the generation of electric sparks

Embodiment Construction

[0027] The core of the present invention is to provide an explosion-proof TBM, which meets the requirements of the national coal mine explosion-proof standard, and can make the tunneling support work at the same time, and the roadway can be formed at one time, so as to improve the tunneling efficiency.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] It should be pointed out that the localizers such as front, back, middle and lower involved in this article are all based on Figure 1 to Figure 5 The components are located in the figure and the positions between the components are defined, and the front and rear are defined based on the driving direction of the explosion-proof TBM; the use of the orientation words is only for the clarity and clarity of the technical solution...

Abstract

The invention discloses an anti-explosion TBM (tunnel boring machine), which includes a cutter head tunneling mechanism used for crushing coal rock, a driving device mounted at a front shield of a shielding device, connected with a cutter head of the cutter head tunneling mechanism and used for driving the cutter head to rotate, and a boosting oil cylinder mounted in a middle shield of the shielding device, wherein electric equipment of the driving device and hydraulic equipment of the boosting oil cylinder are anti-explosion equipment. As the electric equipment and the hydraulic equipment of the anti-explosion TBM are anti-explosion equipment, the anti-explosion TBM avoids the hidden danger of electric spark generation, and can be used in coal mine tunnels with coal dust and gas, and improves the operating safety.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to an explosion-proof TBM. Background technique [0002] With the development of my country's economic construction, energy consumption is increasing rapidly. As the main energy source in my country, its consumption is also increasing, and my country's coal industry has also developed rapidly. [0003] Driving and mining are important links in coal mine production. Rapid excavation of coal mine roadway is a key technical measure to ensure high and stable mine production. High-efficiency mechanized tunneling and support technology has become the development direction of roadway tunneling technology. [0004] At present, the cantilever roadheader is mostly used in coal mine roadway excavation. The cutting range is not the whole section, and the cutting is carried out with picks. For the hard coal rock, the excavation efficiency is low; moreover, the excavation and support operat...
