The invention relates to the technical field of pantograph rising detection, and discloses pantograph rising mechanism rechecking equipment for pantograph air spring expansive force, which comprises a shell, an air spring is movably connected in the shell, an air flow channel is movably connected in the air spring, the surface of the air flow channel is sleeved with an inflation sleeve, a detection box is fixedly connected to the surface of the shell, a hollow channel is fixedly connected to the interior of the detection box, and an airflow rod is movably connected to the right end of the hollow channel. If the steel wire rope is rusty or dislocated at the moment, the motion trail of the lower connecting rod can be influenced, and the speed of airflow flowing out of the surface of the pressure ball can be reduced when the lower connecting rod cannot stretch normally, so that the airflow pressure value on the surface of the pressure ball is increased, the pressure of the pressure ball is reduced, and the airflow flowing into the hollow channel is increased; and the pushing force to the lower connecting rod and the steel wire rope is increased, so that the effects of detecting the steel wire rope part and not influencing the normal proceeding of the pantograph lifting motion are achieved.
本发明涉及受电弓升弓检测技术领域,且公开了一种受电弓空气弹簧膨胀力的升弓机构复查设备,包括壳体,所述壳体的内部活动连接有空气弹簧,空气弹簧的内部活动连接有气流通道,气流通道的表面套接有充气套,壳体的表面固定连接有检测箱,所述检测箱的内部固定连接有中空通道,中空通道的右端活动连接有气流杆。若此时钢丝绳出现锈迹或者错位现象时,均会影响下连杆的运动轨迹,下连杆无法正常伸展便会减慢气流从压力球表面流出的速度,因而压力球表面的气流压力值变大,压力球受压变小,从中空通道涌入的气流变大,加大对下连杆和钢丝绳的推动力,从而达到了既能检测出钢丝绳部位又能不影响升弓运动正常进行的效果。
