为了提高韶山1型电力机车的制造质量,准确而方便地测试受电弓的力、位移、升降弓时间等技术特性,株洲电力机车工厂设计并制成了受电弓试验台,现已投入使用。该试验台由台架、扭矩传感器,位移传感器、磁座钻、操作仪表柜几部分组成。应用电子技术将所测试出的力、位移、时间数据分别由电子数码管显示,并可与高输入阻抗记录仪配合使用,记录位移与力的变化,代替手抄特性数据。试验台的工作原理是:1.力的测量——由电动机行星摆线减速器、蜗轮蜗杆箱、铰索绳滚筒、铰索滑轮、力臂、电磁离合器、扭矩传感器等构成机械传动机构。当徐徐释放或收回绳索时,将受电弓上升、下降的力加在传感器旋轴
In order to improve the manufacturing quality of Shaoshan Type 1 electric locomotive and accurately and conveniently test the technical characteristics of the pantograph such as force, displacement and time for raising and lowering the bow, Zhuzhou Electric Locomotive Factory designed and made a pantograph test stand, which has been put into operation . The test bench by the bench, torque sensors, displacement sensors, magnetic drill, the operation of the instrument cabinet several parts. Application of electronic technology will be tested by the force, displacement, time data by the electronic digital display, and can be used in conjunction with the high input impedance recorder to record the displacement and force changes, instead of hand-copied character data. The working principle of the test stand is: 1. Force measurement - by the motor planetary cycloid reducer, worm gear box, the cable rope roller, the hinge pulley, arm, electromagnetic clutch, torque sensors constitute a mechanical transmission. When slowly release or retract the rope, will be pantograph up, down force plus sensor shaft
