Technical Field

[0001] This application relates to the field of tamping equipment technology, specifically to a support mechanism for a tamping frame and a tamping vehicle. Background Technology

[0002] Tamping is one of the main tasks in the maintenance of ballast railway tracks. It can effectively restore the geometric parameters of the track, improve the stability of the track bed, and ensure the safety of train operation. Existing tamping machines have a small tamping frame that can extend out of the car body and a narrow coverage area. Therefore, the support device of the tamping frame can also extend out of a small range. However, this makes it impossible to tamp all the long sleepers in the turnout area when tamping.

[0051] Example 1

[0052] See Figures 1 to 8 As shown, this application provides a support mechanism for a tamping frame, including a central support device 1, two movable support devices 2, a first drive component 3, and a second drive component 4. Both movable support devices 2 are slidably disposed on the central support device 1, forming a support space 5 between the movable support devices 2 and the central support device 1 for the through-hole of the main arm 72 of the tamping frame 71. The first drive component 3 is drivenly connected to both movable support devices 2 to drive them to slide along the central support device 1, thereby adjusting the distance between the two movable support devices 2. The second drive component 4 is connected to the central support device 1 and drives it to move along the frame 6. The tamping frame support mechanism provided in this application, comprising a central support device 1 and two movable support devices 2, achieves dual-stage telescopic movement, significantly increasing the telescopic range. Simultaneously, the retracted state meets locomotive clearance requirements, satisfying the needs of turnout tamping machines for full coverage of long turnout sleepers in the turnout area, thus expanding the tamping operation range.

[0053] When the support mechanism of the tamping frame 71 of this application is used, such as Figure 7 As shown, the tamping frame support mechanism is installed between the upper and lower beams of the tamping machine frame 6. The tamping frame 71 and the boom 72 end of the boom 72 pass through the support space 5 of the tamping frame support mechanism, which supports them. Figure 8 As shown in the top view, a set of movable support devices 2 corresponds to a set of tamping frames 71 and boom 72. When the tamping frame 71 and boom 72 on one side need to be extended, the second drive component 4 drives the middle support device 1 to move to that side. At the same time, the telescopic component 31 of the first drive component 3 drives the movable support device 2 on that side to continue to extend and change its posture, thereby achieving effective support for the tamping frame 71 and boom 72.

[0054] In some possible implementations, the central support device 1 includes a central body 11 and two side bodies 12, which are respectively disposed on both sides of the central body 11 and extend in opposite directions. Two movable support devices 2 are slidably connected to their respective side bodies 12. The two side bodies 12 extend in the direction of the extension and retraction of the support mechanism, providing a support carrier for the movable support devices 2. The central body 11 connects the two side bodies 12, ensuring overall stability and sturdiness.

[0055] In some possible implementations, the side body 12 includes two guide beams 121 arranged at intervals and in parallel, both of which are connected to the central body 11. The movable support device 2 has two guide sleeves 21, each slidably fitted onto a corresponding guide beam 121. The two guide sleeves 21 are connected, forming the support space 5 between the two guide sleeves 21 and the central body 11. By configuring the side body 12 with two spaced guide beams 121 and the movable support device 2 with two spaced guide sleeves 21, a rectangular support space 5 can be formed, which can effectively support the tamping frame 71 and the boom 72, and also constrain the tamping frame 71 and the boom 72 in the height direction, ensuring that the tamping frame 71 and the boom 72 perform their actions accurately.

[0056] In some possible implementations, the movable support device 2 includes an end connector 22 located on the side of the guide sleeve 21 opposite to the central body 11. The end connector 22 connects to two guide sleeves 21 respectively. The end connector 22 connects to the ends of the two guide sleeves 21 located on the same side, forming a "U" shape, which increases the overall stability and overall connection strength. At the same time, the end connector 22 forms a closed support space 5, preventing the boom 72 from detaching from the tamping frame support mechanism, thus improving safety and the reliability of the mechanism.

[0057] In some possible implementations, a first sliding plate 13 is provided on the surface of the guide beam 121, and a second sliding plate 213 is provided on the inner wall of the guide sleeve 21. At least one of the first sliding plate 13 and the second sliding plate 213 has a lubrication groove 2131 on its surface. When the guide sleeve 21 is fitted onto the guide beam 121, the second sliding plate 213 and the first sliding plate 13 are in contact. The sliding plate reduces the friction between the guide beam 121 and the guide sleeve 21, which not only makes the support mechanism of the tamping frame 71 operate more smoothly, but also extends the service life and maintenance cycle of the first drive component 3, the guide beam 121, and the guide sleeve 21. The lubrication groove 2131 can hold lubricating oil, which further reduces friction, reduces wear, and extends service life.

[0058] In some possible implementations, the first sliding plate is a metal plate, and the second sliding plate is a non-metallic plate. The first sliding plate 13 is welded and fixed to the guide beam 121, and the second sliding plate 213 is detachably connected to the guide sleeve 21. The first sliding plate 13 on the I-beam is made of metal and is welded to the perimeter of the guide beam 121. The second sliding plate 213 inside the guide sleeve 21 is made of non-metallic material, such as nylon, and is detachably installed inside the guide sleeve 21. The second sliding plate 213 is made of a relatively soft material. If wear occurs due to the relative sliding between the guide beam 121 and the guide sleeve 21, it will primarily appear on the second sliding plate 213. The second sliding plate 213 is detachably connected to the guide sleeve 21. If it wears to a certain extent, the second sliding plate 213 can be replaced for continued use.

[0059] In some possible implementations, the guide sleeve 21 includes a base frame 211 and a cover plate 212. The base frame 211 includes a base plate 2111 and side plates 2112 disposed on both sides of the base plate 2111 along its width. The cover plate 212 covers the two side plates 2112, and the cover plate 212 and the side plates 2112 are detachably connected. When the second slide plate 213 needs to be replaced, the cover plate 212 can be removed, and after the second slide plate 213 is replaced, the cover plate 212 is installed back onto the base frame 211. The base plate 2111 is longer than the cover plate 212, resulting in a larger overlap area between the guide sleeve 21 and the central support device 1, while also providing installation space for the cylinder assembly lugs.

[0060] In some possible implementations, the first driving component 3 includes two telescopic components 31, each with one end connected to the central body 11 and the other end connected to the guide sleeve 21 of a corresponding movable support device 2. By controlling the guide sleeves 21 on both sides with the two telescopic components 31 respectively, the sides can be extended or shortened to different degrees as needed. Preferably, the ends of the two telescopic components 31 connected to the central support device 1 share a common connecting seat to save space.

[0061] Example 2

[0062] See Figures 1 to 8 As shown, this application provides a tamping machine, including a frame 6, a support mechanism 100 for the tamping frame as described in Embodiment 1, and a tamping assembly. The support mechanism 100 for the tamping frame is disposed on the frame 6. The tamping assembly includes a tamping frame 71 and a boom 72. The boom 72 is connected to the frame 6 and passes through the support space 5 of the support mechanism 100 for the tamping frame. The boom 72 is supported by the central support device 1 or the movable support device 2. The tamping frame 71 is connected to the boom 72. Figure 7As shown, the tamping frame support mechanism is installed between the upper and lower beams of the tamping machine frame 6. The tamping frame 71 and the boom 72 end of the boom 72 pass through the support space 5 of the tamping frame support mechanism, which supports them. Figure 8 As shown in the top view, a set of movable support devices 2 corresponds to a set of tamping frames 71 and boom 72. When the tamping frames 71 and boom 72 on one side need to extend, the second drive component 4 drives the middle support device 1 to move to that side. At the same time, the first drive component 3 drives the movable support device 2 on that side to extend and change its posture, thereby achieving effective support for the tamping frames 71 and boom 72.
