[0022] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0023] A tamping machine, such as Figure 1 — Figure 5 As shown, the device includes an excavator 1, with a set of liftable track wheel sets 2 at both the front and rear. Each track wheel set 2 includes a wheel frame 4 and track wheels 5 connected to both ends of the wheel frame 4. This device can travel on railway lines. To reduce costs, this device is designed and assembled using the mature excavator 1, and all required power sources come from the engine of the excavator 1.

[0024] Furthermore, such as Figure 3 As shown, to enable this device to travel on both railway lines and conventional roads, the wheel frame 4 is equipped with a connecting frame 7 that is hinged to the first connecting hole 6 of the excavator 1 chassis. A first hydraulic cylinder 8 is located between the connecting frame 7 and the excavator 1 chassis. One end of the first hydraulic cylinder 8 is connected to the third connecting hole 9 located in the middle of the connecting frame 7, and the other end is connected to the second connecting hole 10 located on the excavator 1 chassis. In this embodiment, to increase the connection strength, there are two sets of connecting frames 7. The track wheel assembly 2 can be angularly displaced around the center of the first connecting hole 6 by being driven by the first hydraulic cylinder 8. When traveling on the railway line, the cylinder rod of the first hydraulic cylinder 8 extends, and the track wheel assembly 2 rotates downward around the center of the first connecting hole 6 until the tracks of the excavator 1 are no longer in contact with the railway track; when traveling on a conventional road, the cylinder rod of the first hydraulic cylinder 8 retracts, and the track wheel assembly 2 rotates upward around the center of the first connecting hole 6 until the track wheel 5 is no longer in contact with the road surface. During the displacement of the track wheel assembly 2, the tamping component 3 moves with it until the track wheel assembly 2 is in place.

[0025] The front part of the excavator 1 is further provided with a set of liftable tamping assemblies 3. The tamping assembly 3 comprises a base frame 11, a lifting frame 12, a tamping frame 13 and a tamping head group 14 mounted on the tamping frame 13, the base frame 11 is connected above the front wheel frame 4, the base frame 11 and the lifting frame 12 are provided with a second oil cylinder 15 capable of driving the lifting frame 12 to displace in the height direction, and the tamping frame 13 and the lifting frame 12 are detachably connected through bolts or pins.
