Rail tamping machine with adjustable vibration parameters
The invention relates to a rail tamping machine with adjustable vibration parameters, and belongs to the technical field of railway engineering equipment. The rail tamping machine comprises a bottom beam, guide rods, a machine frame, a hydraulic power unit, a top beam, a clamping oil cylinder, a lifting oil cylinder, a motor, a frequency converter, a big belt wheel, pick arms, tamping picks, shaft sleeves, an eccentric shaft, a small belt wheel, screw rods and nut shafts. When hand shanks of the screw rods are rotated, the nut shafts are driven to slide up and down in guide grooves in the pick arms, so that the lengths of upper pick arms can be changed, and the amplitude of the acmes of pick palms of the tamping picks can be regulated; the variable-frequency coefficient of the frequency converter is regulated, and the actual output rotating speed of the motor is changed, so that the vibration frequency of the acmes of pick palms of the tamping picks can be regulated. When the rail tamping machine is adopted to tamp ballasted track beds, the amplitude and the vibration frequency of the pick palms of the tamping picks can be regulated in an infinite manner, so that the pertinence and the sensitivity of the tamping operation are enhanced, the tamping effects and the tamping efficiency are improved, and besides, the rail tamping machine is simple in structure and convenient to use.
