技术领域technical field
本发明涉及一种采掘装备领域，特别是一种截割煤岩工作机构。The invention relates to the field of mining equipment, in particular to a working mechanism for cutting coal and rock.
背景技术Background technique
在煤炭行业纲领性文件《关于促进煤炭工业健康发展的若干意见》中，在全国煤炭工业科学技术大会上以及国家发改委出台的煤炭行业结构调整政策中，都涉及到发展大型煤炭井下综合采煤设备等内容。煤矿巷道的快速掘进是煤矿保证矿井高产稳产的关键技术措施。高效机械化掘进是保证矿井实现高产高效的必要条件之一，也是巷道掘进技术的发展方向。我国煤巷高效掘进方式中最主要的掘进机械为悬臂式掘进机。悬臂式掘进机是集截割、装运、行走、操作等功能于一体，主要用于截割任意形状断面的井下岩石、煤或半煤岩巷道。现在国内的掘进机设计基本能满足国内的需求，但离国际先进技术还有一定距离。且国内目前岩巷施工仍以钻爆法为主，重型悬臂式掘进机用于大断面岩巷的掘进在我国处于试验阶段。炮掘技术存在安全性低、巷道二次破坏、粉尘大、掘进速度慢、服务年限短、维修费用高等问题。因此，能够胜任截割硬岩的悬臂式掘进机急需技术创新。截割头是掘进机的执行部件，其性能优劣，直接决定了煤炭开采的经济效益。为了加快高效掘进装备的国产化进程，提高煤岩截割效率，对截割头进行结构设计势在必行。In the coal industry programmatic document "Several Opinions on Promoting the Healthy Development of the Coal Industry", in the National Coal Industry Science and Technology Conference and in the coal industry structural adjustment policy issued by the National Development and Reform Commission, the development of large-scale coal underground comprehensive coal mining equipment is involved and so on. Rapid excavation of coal mine roadway is a key technical measure for coal mines to ensure high and stable mine production. High-efficiency mechanized excavation is one of the necessary conditions to ensure high production and high efficiency in mines, and it is also the development direction of roadway excavation technology. The most important tunneling machine in the high-efficiency tunneling method of coal roadways in my country is the cantilever type roadheader. The cantilever roadheader integrates the functions of cutting, loading, walking, and operation, and is mainly used for cutting underground rock, coal or semi-coal roadways with arbitrary cross-sections. At present, the design of domestic roadheaders can basically meet the domestic needs, but there is still a certain distance from the international advanced technology. Moreover, the current domestic rock roadway construction is still dominated by the drill and blast method, and the use of heavy-duty cantilever roadheaders for large-section rock roadway excavation is in the experimental stage in my country. The blasting technology has problems such as low safety, secondary damage to the roadway, large dust, slow excavation speed, short service life, and high maintenance costs. Therefore, the cantilever roadheader capable of cutting hard rock is in urgent need of technological innovation. The cutting head is the executive part of the roadheader, and its performance directly determines the economic benefits of coal mining. In order to speed up the localization process of high-efficiency tunneling equipment and improve the efficiency of coal and rock cutting, it is imperative to design the structure of the cutting head.
悬臂式部分断面掘进机主要用于煤巷及半煤岩巷道掘进，前悬臂式部分断面掘进机的工作机构采用多截齿配置的截割头，从截割性能上，难以很好地满足截割f>8以上的全岩巷，不仅刀具磨损十分严重，粉尘量大能耗明显增高，因此，研制适用于全岩巷道的悬臂式部分断面掘进机工作机构，十分迫切。The cantilever type partial-section roadheader is mainly used for coal roadway and semi-coal-rock roadway excavation. The working mechanism of the front cantilever type partial-section roadheader adopts a cutting head configured with multiple picks. From the perspective of cutting performance, it is difficult to meet the cutting requirements Cutting a whole-rock roadway with f >8 or more not only causes severe tool wear, but also significantly increases energy consumption due to the large amount of dust. Therefore, it is very urgent to develop a cantilever-type partial-section roadheader working mechanism suitable for whole-rock roadways.
