[0033] The top of the tamping hammer 22 is connected to the floating plate 25 via a connecting rod 24. The top of the floating plate 25 is connected to the lifting plate 27 via a spring A26. The bottom of the lifting plate 27 is connected to a slide rod 31. The slide rod 31 slides through the floating plate 25 and connects to a limit block 33. A spring B32 is provided between the limit block 33 and the floating plate 25 and is sleeved on the slide rod 31.

[0034] The protective cover 11 is provided with a toggle member for adjusting the reciprocating lifting of the lifting plate 27, and the protective cover 11 is provided with a guide member for the stable lifting of the lifting plate 27 and the floating plate 25;

[0035] In this embodiment, when the device moves, the moving wheel 16 can be used to move on the ground, or the rail roller 18 can be used to roll on the rail. When in use, the tamping disk 19 is aligned with the tamping position, and the toggle member adjusts the lifting disk 27 to lift and lower back and forth. The lifting disk 27 drives the floating disk 25 to lift and lower through the spring A26. At the same time, when the slide bar 31 is lifted and lowered, the squeezing or pulling of the spring B32 will also drive the floating disk 25 to move. The floating disk 25 drives the tamping hammer 22 to move through the connecting rod 24. The tamping disk 19 vibrates back and forth to tamp the target position. Due to the drive of the spring A26 and the spring B32, the lifting disk 27 will drive the slide bar 31 to rise when it rises, and the spring A26 and the spring B32 will drive the tamping hammer 22 to float, so that the tamping hammer 22 continues to float, and the tamping disk 19 performs the tamping operation.

[0036] In another embodiment, the mounting part includes a docking post 20, which is connected to the top of the tamping disk 19. The bottom of the tamping hammer 22 is provided with a docking hole 23 for docking with the docking post 20. One side of the tamping hammer 22 is threadedly connected to a fixing bolt 21, and the docking post 20 is provided with a mounting hole that cooperates with the fixing bolt 21. When the tamping disk 19 is installed, the docking post 20 is docked into the docking hole 23 and is fixed using the fixing bolt 21. In actual use, the tamping disk 19 of corresponding size and model can be replaced according to needs.

[0037] like Figure 3 As shown, in another embodiment, the springs A26 are symmetrically arranged in two groups, and the slide rods 31 are symmetrically arranged in two groups, so that the floating plate 25 can be lifted and lowered stably.

[0038] In another embodiment, the toggle member includes a motor 14 and a connecting rod 28. The motor 14 is installed on one side of the protective cover 11. A control box corresponding to the motor 14 is installed at the bottom of the frame 12, and the control box selects existing control components according to actual needs; a drive disk 29 is installed on the motor shaft of the motor 14, and one end of the connecting rod 28 is rotatably connected to the top of the lifting disk 27, and the end of the connecting rod 28 away from the lifting disk 27 is rotatably connected to the eccentric point of the drive disk 29 away from the motor 14; when the motor 14 is working, it can drive the drive disk 29 to rotate, and the lifting disk 27 is driven by the connecting rod 28 to perform reciprocating lifting motion.

[0039] like Figure 3 As shown, in another embodiment, the guide member includes a support plate 35 and two groups of guide rods 30 connected to the top of the support plate 35, two groups of support rods 34 are connected to the support plate 35, and the support rods 34 are connected to the inner wall of the protective cover 11 on the side away from the support plate 35. The floating plate 25 and the lifting plate 27 are both provided with through holes for the guide rods 30 to slide through, and the guide rods 30 are connected to the frame 12 on the end away from the support plate 35;

[0040] The arrangement of the support plate 35 , the support rods 34 and the guide rods 30 enables the floating plate 25 and the lifting plate 27 to be lifted and lowered stably.

[0041] like Figure 1 and Figure 6 As shown, in another embodiment, the axis of the rail roller 18 is perpendicular to the axis of the moving wheel 16, and the axis of the rail roller 18 is parallel to the axis of the lifting plate 27; the rail roller 18 can roll along the rail, making it convenient to move the device to the target position for use.

[0042] In another embodiment, a handle 13 is connected to one side of the frame 12 to facilitate the use of the operating device.

[0043] The working principle of the present utility model is: when the device moves, the moving wheel 16 can be used to move on the ground, or the rail roller 18 can be used to roll on the rail. When in use, the tamping disk 19 is aligned with the tamping position, and when the motor 14 is working, it can drive the driving disk 29 to rotate, and the lifting disk 27 is driven by the connecting rod 28 to perform reciprocating lifting and lowering motion. The lifting disk 27 drives the floating disk 25 to lift and lower through the spring A26. At the same time, when the slide bar 31 is lifted and lowered, the floating disk 25 is also driven to move by the squeezing or pulling of the spring B32. The floating disk 25 drives the tamping hammer 22 to move through the connecting rod 24, and the tamping disk 19 vibrates reciprocatingly to tamp the target position. Due to the drive of the spring A26 and the spring B32, the lifting disk 27 will drive the slide bar 31 to rise when it is lifted, and the spring A26 and the spring B32 will drive the tamping hammer 22 to float, so that the tamping hammer 22 continues to float, and the tamping disk 19 performs the tamping operation.
