【摘要】：与传统输送机相比,气垫带式输送机具有运量大、成本低、持续运输、环保节能、占地面积小等技术和经济优势。在运输行业各领域,尤其是煤炭运输领域,气垫带式输送机得到了广泛地应用。调查表明,气垫带式输送机在输送物料的过程中经常发生故障,设备存在安全隐患。因此,对气垫带式输送机安全性分析有重要的意义。因此,本论文以提高气垫带式输送机的安全性为研究目的,围绕气垫带式输送机展开研究。首先,本论文阐述了气垫带式输送机的构造、工作原理；对多家企业的故障数据资料进行整理和分析,将故障分为皮带故障、驱动系统故障、钢结构故障以及气室故障四种故障模式,同时对系统故障进行了统计分析。其次,本论文对系统的故障类型和影响进行分析,具体内容包括故障描述、故障原因分析、故障影响分析、故障类型分析以及故障危险度计算；基于上述故障模式和影响分析,本文将影响气垫带式输送机系统安全性的故障因素归纳为使用寿命、操作不当、安装不当、材质不良；选取专家组,由各专家提供自己的直觉模糊认知信息,采用直觉模糊混合平均(IFHA)集成算子和直觉模糊加权平均(IFWA)集成算子进行集成运算,由得分函数计算各因素的得分值,进行重要性排序,并提出相应的改善措施和意见。最后,本文根据系统资料,采用故障树分析法对系统的基本故障进行定量分析,计算可靠度；基于马尔柯夫过程模型,以旁联可修复系统模型计算了气垫式输送机各子系统的有效度等指标,以串联可修复系统模型计算了系统的有效度等指标,寻找系统的薄弱环节。本论文对气垫带式输送机的针对性设计和改善方法可以有效提高气垫带式输送机的安全性与可靠性,对提高日常生产活动的稳定性、安全性及生产效率有一定的应用价值。
[Abstract]:Compared with the traditional conveyor, with large volume, low cost, sustainable transportation, environmental protection and energy saving of air cushion belt conveyor, small and economic advantages. In the field of transportation industry, especially in the field of coal transportation, air cushion belt conveyor is widely used. The investigation shows that the air cushion belt conveyor in conveying material of the equipment failure often occurs, there are security risks. Therefore, the air cushion belt conveyor safety has important significance.
Therefore, in order to improve the safety of the air cushion belt conveyor, the purpose of this paper is to study the air cushion belt conveyor.
First, this paper describes the structure and working principle of air cushion belt conveyor; fault data on the number of enterprises are sorted and analyzed, the fault is divided into fault belt, driving system fault, the fault of steel structure and chamber failure four kinds of failure modes of system fault are analyzed.
Secondly, analyze the fault type and the effect of the system, the specific contents include fault description, fault analysis, fault analysis, fault analysis and fault risk calculation; analysis the failure mode and effect based on the failure factors influencing air cushion belt conveyor system security into the service life and operation unsuitable, improper installation, poor quality; selected by the group of experts, experts provide intuitionistic fuzzy cognitive information, using intuitionistic fuzzy hybrid averaging (IFHA) operator and intuitionistic fuzzy integrated with Quan Pingjun (IFWA) integrated operator integrated operations, each factor score value calculated by the score function, the order of importance, and proposed the improvement the corresponding measures and suggestions.
Finally, according to the data, using fault tree analysis method for quantitative analysis of the basic fault system, calculation of reliability; Markov process model based on standby repairable system model with the effective index of air cushion conveyor subsystems were calculated with the series repairable system model index system the calculation for the weak links of the system.
The targeted design and improvement method of air cushion belt conveyor can effectively improve the safety and reliability of air cushion belt conveyor, and it has certain application value to improve the stability, safety and production efficiency of daily production activities.
