摘要提升是煤炭行业里的重中之重。
目前煤矿上大多采用多绳摩擦式提升机。
是依靠钢丝绳与摩擦轮衬垫之间的摩擦力来提升。
由于众多因素的影响，在使用一段时间后,会使各钢丝绳之间受力不均、张力不平衡，这将会造成钢丝绳的疲劳破坏和摩擦衬垫的早期报废，甚至会造成滑绳、断绳等重大事故。
因此，在线检测各钢丝绳张力的情况一致，保持钢丝绳受力一致对延长钢丝绳的寿命、减轻衬垫磨损、保证设备安全运行有着很重要的意义。
本文在参考分析其他资料的基础上，设计了摩擦提升机钢丝绳张力监测系统，该测试系统分为机械装置和信号测试两部分。
机械装置是由支架压轮底座轴轴承等主要部件组成。
并根据实际工作情况等因素，合理选择加工材料，确定支架和底座的外部尺寸，并对轴及轴承等进行强度校核和寿命计算。
以来完成用直接接触法测量各钢丝绳的张力。
测试部分依次由弹性元件放大装置滤波装置信号转换装置处理装置显示装置组成。
从而使所测得的张力一步步由力信号通过弹性元件转换成电信号再通过信号放大滤波采集进而显示出钢丝绳的张力的大小。
该测试系统将用于实践，会对安全生产起到积极的作用。

Relying on wire rope and the friction between the friction wheel liner to improve. Because many factors in the use of a period of time, bring the rope were among the Shouli Bu, tension imbalance, which will result in fatigue failure of wire rope and the friction lining of early retirement, or even cause slippery rope, broken rope and other major incidents. Therefore, online detection of the rope tension in line, keeping the same wire by the force of the rope to extend life, reduce pad wear, to ensure the safe operation of equipment has very important significance. Analysis of other information in the reference paper based on the design of friction hoist rope tension monitoring system, the test system is divided into mechanical devices and signal test two parts. Mechanical device is the base from the support roller shaft bearings and other major components. Work based on factors such as actual and reasonable material selection process, make sure the support and the base of the external dimensions, and the shaft and bearing, etc. check the strength and life prediction. Since the completion of direct contact with the wire rope tension measurement. Test parts of this device by th e e l a s t i c element to enlarge the signal conversion device Filter display device component processing device. So that the tension measured step by step from the force signals into electrical signals through the elastic element and then collected by filtering the signal amplification and thus show the size of wire rope tension. The test system will be applied in practice, it will play a positive role safety.Key word s：multi-rope friction hoist；rope；tension sensor目录摘要 (I)Abstract (II)第1章绪论 (1)1.1 课题的研究意义和内容 (1)1.2 国内外发展趋势 (2)第2章钢丝绳张力检测方案系统设计 (4)2.1 设计方案的制定 (4)2.1.1方案一（三点法） (4)2.1.2 方案二（直接接触法） (5)2.2 检测装置部分的设计 (7)2.3 信号处理部分的设计 (8)第3章钢丝绳张力检测装置的结构设计 (10)3.1 引言 (10)3.2 检测装置的结构设计 (11)3.2.1 压轮的设计 (11)3.2.2 轴的设计计算 (11)3.2.3 轴承的选择设计计算 (13)3.2.4 弹性元件的设计计算 (14)3.2.5 支架的设计 (17)3.2.6 支架的移动和固定 (17)3.3 力传感器的设计 (19)3.3.1 传感器的简述 (19)3.3.2 应变片的选择 (20)3.3.3 电阻应变片的测量电桥电路 (22)第4章钢丝绳张力检测处理系统的硬件设计 (25)4.1引言 (25)4.2传感器信号的前置放大 (25)4.3滤波电路设计与分析 (27)4.4 A/D转换电路的设计 (30)4.5 8051芯片的介绍 (32)4.6 I/O口扩展芯片8155的介绍 (33)4.7操作控制和显示器电路的设计 (35)4.7.1 操作控制的设计 (35)4.7.2 显示器接口电路设计 (36)4.8 打印机接口电路的设计 (39)4.9 张力测试系统图 (40)结论 (41)致谢 (42)参考文献 (43)DirectoryAbstract (I)Abstract (II)Chapter 1 INTRODUCTION The (1)1.1 The issue of meaning and content (1)1.2 The development trend of domestic and foreign (2)Chapter 2 Design of Wire Rope Tension Detection Scheme (2)2.1 The design of the development (4)2.1.1 Option One (three-point method) (4)2.1.2 Option II (direct contact method) (5)2.2 The detector part of the design (7)2.3 The design of signal processing (8)Chapter 3 Structural Steel Design tension detecting device (10)3.1 Introduction (10)3.2 Detection of Structure Design (11)3.2.1 Design of the roller (11)3.2.2 shaft design calculation (11)3.2.3 Design and Calculation of bearing selection (13)3.2.4 Calculation of elastic components (14)3.2.5 Design Support (17)3.2.6 Support mobile and fixed (17)3.3 Force Sensor (19)3.3.1 Sensor Description (19)3.3.2 Strain gage selection (20)3.3.3 Measurement of electrical resistance strain gauge bridge circuit (22)Chapter 4, Wire Rope Tension Measurement processing system hardware design (25)4.1 Introduction (25)4.2 Sensor signal preamplifier (25)4.3 Filter Circuit Design and Analysis (27)4.4 A / D converter circuit (30)4.5 8051 chip introduced (32)4.6 I / O port expansion introduction of chip 8155 (33)4.7 Design of operational control (35)4.7.1 Design of operational control (35)4.7.2 display interface circuit design (36)4.8 Printer Interface Circuit (39)4.9 Tension test system diagram (40)Conclusions (41)Acknowledgements (42)References (43)第1章绪论1.1 课题的研究意义和内容多绳摩擦式提升机是矿山提升物料的主要设备，它是依靠钢丝绳与摩擦轮衬垫之间的摩擦力来提升。
