Sleeper ballast bed stepless vibration reduction gain device based on angle amplification principle
The invention relates to the technical field of sleeper ballast beds, in particular to a sleeper ballast bed stepless vibration reduction gain device based on the angle amplification principle. The sleeper ballast bed stepless vibration reduction gain device based on the angle amplification principle specifically comprises a sleeper base body, a transmission mechanism, a balance weight trolley and an energy absorption mechanism. The upper rotating shaft is rotationally connected with the upper movable circular groove, and the lower rotating shaft is rotationally connected with the lower movable circular groove; the included angle between the longitudinal axis and the horizontal center line is an amplification angle alpha; when the upper rotating shaft is located in the lowermost upper movable circular groove and the lower rotating shaft is located in the uppermost lower movable circular groove, the amplification angle alpha is the minimum amplification angle alpha min, and when the upper rotating shaft is located in the uppermost upper movable circular groove and the lower rotating shaft is located in the lowermost lower movable circular groove, the amplification angle alpha is the maximum amplification angle alpha max; the amplification angle alpha comprises a combination mode of the group number of the upper movable circular grooves and the group number of the lower movable circular grooves, and the amplification angle alpha varies steplessly between 45 degrees < = alpha min < = alpha < = alpha max < = 90 degrees. The stepless vibration reduction device has the advantage of realizing stepless vibration reduction.
