Description

Technical Field

[0001] The present application relates to the technical field of railway maintenance machinery, and in particular to a double-sleeper tamping device. Background Art

[0002] Tamping operation is one of the main tasks of ballasted railway track bed maintenance. Tamping can effectively improve the stability of the railway track bed and ensure the safety of train running. In order to improve the efficiency of tamping operation and ensure that the tamping device can adapt to the railway track bed with different sleeper spacing, double-sleeper tamping operation or three-sleeper tamping operation is widely used in mainline tamping operation. Compared with the single-sleeper tamping device, the double-sleeper tamping device or the three-sleeper tamping device improves the tamping efficiency and can effectively adapt to different sleeper spacings compared to the multi-sleeper tamping device. The currently widely used double-sleeper and three-sleeper tamping devices adopt the eccentric shaft connecting rod swing vibration principle, in which each tamping arm is connected to the eccentric shaft to transmit the excitation generated by the eccentric shaft to the tamping pick.

[0003] However, in the existing double-sleeper tamping device or three-sleeper tamping device, all clamping cylinders are directly connected to the eccentric shaft. Affected by the spatial layout and the change of the clamping angle of the outer pick arm, the inner clamping cylinder is subjected to torque when the outer pick arm is clamped, thereby affecting the service life of the inner clamping cylinder and even causing oil leakage. Therefore, it is necessary to develop a tamping device structure so that the clamping cylinders are subjected to force along the cylinder rod instead of torque, thereby increasing the service life of the clamping cylinders and reducing the maintenance cost of the tamping device.
