Embodiment Construction
[0021] The present invention will be further described below in conjunction with drawings and embodiments.
[0022] Figure 1 to Figure 7 An embodiment of the present invention is shown, and the excitation hydraulic cylinder in this embodiment is a double-rod hydraulic cylinder.
[0023] Such as figure 1 As shown, the tamping device is fixed on the frame 22 of the tamping trolley 15 . The tamping device comprises a tamping box body 23 capable of lower insertion movement, an inner tamping head and an outer tamping head installed oppositely on the two sides of the tamping box body 23 . The lower insertion movement of the tamping box 23 is realized by the lifting hydraulic cylinder 1 on the tamping trolley 15. In order to prevent twisting and deflection during the lower insertion of the tamping box 23, two vertical guides are installed on the tamping trolley frame 22. Column 2, these two guide columns have also ensured the lower insertion depth of tamping box 23.
