摘　　要：目前国内生产的气动绞车相比与国外性能较差,进行煤炭开发作业过程中经常会出现事故。因此设计了一种新型的塔架式绞车性能实验台以测试绞车性能,并详细设计了一种基于霍尔传感原理的绳速测试机构,对其进行了测试精度和受力的实验分析。该测试机构的测试误差在7%以内,且误差在绳速较低时较高,随着绳速的增大逐渐减小,当绳速稳定时,误差值也基本稳定不变;测试机构进行10 t气动绞车性能测试时,测试机构所受的最大应力远小于其屈服应力,因此当进行10 t以下气动绞车性能测试时,不需要对测试机构进行受力分析;而当其进行10 t及以上气动绞车性能实验时,由于钢丝绳的加速度很小,且选取的安全系数较大,可以忽略动载拉力对测试机构进行受力分析。At present, the performance of domestic air winch is poor compared with foreign ones, and breakdown often occurs on the domestic ones during the operation. Therefore, this paper designed a new tower type air winch performance test platform and rope speed test mechanism to proceeds winch performance test. The rope speed test mechanism is based on hall sensor was detailed designed. Test accuracy and its stress of the mechanism was analyzed by conducting test. The mechanism＇s test error is less than 7% which would be high when the speed of the rope is low, and with the speed grows up the error becomes smaller. The error would be stable when the speed of rope is stable. The max stress on the mechanism when it is conducting test for 10 t air winch is far below its yield strength, thus when the test air winch is below 10 t we do not need to calculate the stress on the mechanism;and when the test air winch is above 10 t, because the acceleration of the wire rope is very small and the safety factor selected is large, thus the dynamic load emerged due to the acceleration can be ignored.
