【摘要】：鉴于我国煤矿成套采掘装备研发设计没有试验验证平台的现状,针对煤矿井下实际工作环境,在地面上建立1∶1的高端综采成套装备试验平台,重点研究探讨了采煤机和刨煤机成套装备关键力学参数测试平台建设方案,并对其理论与关键技术进行研究。该平台可实现液压拉杆拉力、摇臂关键截面应力应变、滚筒转矩、链轮振动特性、刮板输送机力学参数、刨煤机效率、刨煤机工作功率等参数的测试。通过以采煤机截割部振动特性测试结果为例,对其与截割特性间关系进行研究;并以26号液压支架测试结果为例,对其工况特性进行评价。结果表明,高端综采成套装备试验平台测试结果可靠,可实时处理综采成套装备性能参数和结构参数,以提高综采装备工作性能,并为综采成套设备提供设计、制造、检验技术支撑。
[Abstract]:In view of the fact that there is no test and verification platform for the R & D design of complete sets of mining equipment in coal mines in China, in view of the actual working environment in coal mines, a 1:1 high-end fully mechanized mining equipment test platform is established on the ground. The construction scheme of key mechanical parameters test platform for shearer and planer equipment is studied and discussed, and its theory and key technology are studied. The platform can test the tension of hydraulic pull rod, the stress and strain of the key section of rocker arm, the torque of drum, the vibration characteristics of sprocket, the mechanical parameters of scraper conveyor, the efficiency of planer, the working power of planer and so on. The relationship between vibration characteristics and cutting characteristics of shearer is studied by taking the test results of vibration characteristics of cutting part of shearer as an example, and the working conditions are evaluated by taking the test results of No. 26 hydraulic support as an example. The results show that the test results of the test platform for high-end fully mechanized mining equipment are reliable, and the performance parameters and structural parameters of fully mechanized mining equipment can be processed in real time in order to improve the working performance of fully mechanized mining equipment and to provide design and manufacture for fully mechanized mining equipment. Test technical support.
