Sliding type control device of mine railway overspeed car arrester

The utility model discloses a sliding type control device of a mine railway overspeed car arrester. The sliding type control device is composed of a hanging scaffold, a small dumping tray, a hook and an oscillating bar together, wherein the hook is arranged on the small dumping tray. A sliding runway is installed at the position where the oscillating bar is hinged, and a long groove of the sliding runway is made of a steel plate with the thickness being 20 mm, wherein the opening of the long groove is downward, the vertical length of the long groove is 200 mm, the width of the long groove is larger than the diameter of the oscillating bar, and the oscillating bar is installed in the long groove of the sliding runway. According to the sliding type control device, the potential safety hazards of derail generated when the oscillating bar supports a light car, deformation generated when a loaded car supports the oscillating bar and false operation of the car arrester are fundamentally eliminated; meanwhile, frequ
