1摘 要矿车在煤矿井下运输中占有十分重要的地位，煤矸粘结矿车车底是煤矿生产运输过程中存在的一个普遍问题。经常而及使地清扫矿车车箱式提高矿井轨道运输效率的重要因素。不论煤质，粒度组成及含水量如何，由于煤矿生产环境的恶劣，加之在运输的过程中的振动等原因，卸车之后总会有少量的煤炭，煤矸等易粘结的物料粘结在矿车车箱底部及邻帮若不将这些残留煤，岩粉及时清除干净，则会越积越厚，越积越结识，增加了矿车自重，使矿车的有效容积减少，它不仅直接影响着矿车的运输能力，造成了运输系统的紧张状况，而且增加了电力资源的浪费，甚至使电机车运输是空列起动发生困难，所以清理车底的问题，在煤矿就显得尤为重要。本设计在传统机械矿车清车机的基础上加入了液压系统，由摩擦离合器控制行走部该为液压控制，安装了多路电磁换向阀，分别控制清车机前后，左右的移动以及摇臂的运动，克服了摩擦离合控制因打滑无法清理矿车车底粘结物的弊端。关键词：关键词： 清车机；液压；矿车 2ABSTRACTMine car plays an important part in the coal mine underground haulage. The gaugue felt on the bottom of the coal car is one of the common problems on the process of coal production and transportation. To clean the compartment of mine car frequently and promptly is a significant way of raising the efficiency of mine pit rail haulage. No matter the quality of coal, the size composition and water content as well, due to the bad environment of coal production and the vibration in the process of transportation, there always has some coal and other materials left which was very easy to cake on the bottom of the mine car after unloading. If we do not clean these remaining coal and rock meal soonly, they would be heavier and solider, which would increase the weight of mine car so that decrease the effective volume of it. Then it would not only affect the transportation ability of mine car directly and make the intense condition of the transportation system, but also increase the waste of electric power, and even make substantial difficulty in starting the spacial vehicle while transporting the electrical machinery truck. So cleaning the bottom of the mine car become espectially important. This design add the hydraulic system on the basis of traditional cleaning machine for mechanical mine car. It changes clutch control into the hydraulic control, and is added the multi-channel electromagnetism cross valves which controlled the all round migration of cleaning machine and the movement of the rocking shaft. It also overcomes the shortcoming that the friction control cannot clean the remainings on the bottom of mine car due to its splitting.Keyword: Pure car machine; Hydraulic pattern; Mineral car3目录目录1 1 绪论绪论.5 5 1.11.1 国内几种矿用清车机简介国内几种矿用清车机简介.5 5 1.21.2 液压矿车清车机的特点液压矿车清车机的特点.9 9 1.31.3 液压式双圆盘截齿矿车清车机简介液压式双圆盘截齿矿车清车机简介.1010 1.41.4 与原机械式矿车清车机的比较与原机械式矿车清车机的比较.1212 1.51.5 矿车清车机设计的目的矿车清车机设计的目的.1313 2 2 总体设计的方案确定总体设计的方案确定.1414 2.12.1 方案的制定原则方案的制定原则.1414 2.22.2 本设计方案的规划本设计方案的规划.1515 2.2.12.2.1 清车机各部分的设计清车机各部分的设计.1515 2.2.22.2.2 结构设计结构设计.1717 2.2.32.2.3 可行性和必要性分析可行性和必要性分析.1818 2.32.3 设计方案的内容总结设计方案的内容总结.1919 3 3 截割部设计截割部设计.2020 3.13.1 截割头的设计要求截割头的设计要求 .2020 3.23.2 截割头的设计截割头的设计.2121 3.2.13.2.1 截齿截齿 .2121 3.2.23.2.2 螺旋滚筒螺旋滚筒 .2121 3.33.3 主要参数的设计主要参数的设计.2323 3.3.13.3.1 螺旋机构的回转直径的确定螺旋机构的回转直径的确定 .2323 3.3.23.3.2 合理确定螺旋切削机构的转速和进给速度合理确定螺旋切削机构的转速和进给速度 .2424 3.3.33.3.3 螺旋切削机构驱动功率估算螺旋切削机构驱动功率估算 .2525 3.43.4 截割臂的设计截割臂的设计.2525 3.4.13.4.1 截割臂的基本要求截割臂的基本要求.2626 3.4.23.4.2 截割臂的设计计算截割臂的设计计算.2626 3.53.5 仰俯液压缸的设计仰俯液压缸的设计.2828 3.5.13.5.1 液压缸工作压力及主要结构尺寸的计算液压缸工作压力及主要结构尺寸的计算 .2828 3.5.23.5.2 液压缸壁厚和外径的计算液压缸壁厚和外径的计算.3131 3.5.33.5.3 液压缸缸盖厚度的确定液压缸缸盖厚度的确定.3434 3.5.43.5.4 液压缸缸体长度的确定液压缸缸体长度的确定.
