| [摘要]矿用钢丝绳摩擦衬垫实验平台，其中主要包括四个部分，主要为支撑台架、加载系统、动力系统和测量系统。支撑台架包括底梁，支撑立柱在底梁两端，滑轮支架和调节支架安装在支撑立柱上。滑轮支架上安装着定滑轮，调节支架上安装着固定挂钩，底梁中部设有轴承座。摆动杆中部通过轴承铰接在轴承座上，同时摆动杆上端装有摩擦衬垫，摩擦衬垫上开设一道弧形凹槽；加载系统包括通过摩擦衬垫弧形凹槽的钢丝绳，钢丝绳一端与固定挂钩相连接，其中钢丝绳另一端则绕过定滑轮后与液压缸活塞杆相连接；激振器是动力系统的一部分，激振器通过连杆与摆动杆下端实现铰接；拉力传感器和应变片则属于测量系统。搭建起来的实验平台可以用来模拟摩擦式提升机实际工况，可实现变频率、变幅值、变载荷及变弧度摩擦试验。26163 [毕业论文关键词]测量系统、摩擦衬垫、液压缸 Wire rope friction pad test platform measurement system design [Abstract]Hoist friction pad of micro slip test platform, which includes a support gantry loading systems, power systems and measuring systems. Support carriage includes a bottom beam, a support column in the bottom ends of the beam, pulley bracket and adjust the bracket mounted on the support post. Pulley bracket on the fixed pulley, fixed hooks with adjustable mounting bracket, bottom beam has a central bearing. By the middle of the swing lever hinged bearing in the bearing housing, while oscillating rod end mounted friction pad, set up a curved recess friction pad; loading system includes a friction pad curved groove rope, wire rope at one end and fixed hook connected to the other end of which bypasses the fixed rope pulley connected to the rear cylinder piston rod; exciter is part of the power system, the exciter achieve articulated by the lower end of the connecting rod and the swing rod; tension and strain gauge sensors are belonging to the measuring system. The present invention can simulate friction hoist the actual working conditions, enabling variable frequency, variable amplitude, variable load and variable curvature of the micro-slip friction test.
