Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to an improvement in a ballast compactor that compacts ballast on the track bed near both ends of sleepers in the longitudinal direction while running on the rails of a railway track. It is.

``Conventional technology'' In general, after track maintenance work on railway tracks, such as track bed tamping work using multiple tie tampers after correcting the track, track bed resistance (which occurs when the sleepers in the ballast track bed move horizontally) In order to restore this reduced bed resistance, a ballast compactor is used to compact the ballast near both ends of the sleeper in the longitudinal direction.

As shown in FIG. 2, the conventional ballast compactor 1 includes a truck 3 that can run on rails 2, and a compaction plate 4 equipped with a hydraulic motor, pneumatic motor, electric motor, etc. A compacting device 8 is constructed by attaching the vibration device 5 used above, and applies vertical vibration to the compaction plate 4 by the vibration device 5 to compact the ballast 7 of the trackbed near both longitudinal ends of the sleepers 6. and one end is rotatably connected to this compacting device 8 via a pin 9,
The other end is rotatably attached to one link 11 on the truck 3 via a pin 10, the rod side is rotatably connected to this link 11, and the cylinder side is rotatable on the truck 3. A setting storage hydraulic pressure is attached to the unit and is attached to the link 11 to lower the compacting device 8 onto the ballast 7 during work and set it to the working state, and to raise it from above the ballast 7 and maintain it within the vehicle limit when driving. It consisted of a cylinder 12, a power unit 13 and an operation panel 14, which were provided on the truck 3 and operated the compacting device 8, the setting storage hydraulic cylinder 12, and the like.

Then, during work, the power unit 13 is started, and the hydraulic cylinder 1 for storage is set using the operation panel 14.
2 to lower the compacting device 8 via the links 11 onto the ballast 7 on the track bed near both longitudinal ends of the sleepers 6, and then operate the vibration device 5 using the operating panel 14 to compact the compacting device 8. While vibrating the solid plate 4 in the vertical direction, the ballast compactor 1
by yourself or by other track maintenance vehicles such as multiple tie tampers or motor cars.
The ballast 7 was compacted by traveling along the top in the direction of the arrow 15 together with a compacting device 8.

"Problems to be Solved by the Invention" However, such a conventional ballast compactor 1 has a structure in which the compacting device 8 can be moved down to follow the surface of the ballast that is being compacted and settled. One end of the link 11 is rotatably mounted on the trolley 3 via a pin 10 and the other end of the link 11 is attached via a pin 9 to allow movement from the lower surface of the uncompacted ballast to the higher surface of the uncompacted ballast. Since they are rotatably connected, there is no problem when the level difference between the compacted and uncompacted ballast surfaces is small, but if the level difference is large, the compacting device 8 may become compacted. As a result, the tip of the compaction plate 4 plunges into the uncompacted ballast, as shown by the two-dot chain line in FIG. When the compacting device 8 moves in the direction shown in FIG. 1, the rear end of the compacting device 8 is lifted up while the tip end is pushed into the ballast, resulting in a problem that the ballast cannot be compacted.

In addition, if extra ballast is piled up near the ends of the sleepers in order to replenish and compact the ballast near the longitudinal ends of the sleepers, the compaction plate 4 of the compacting device 8 is I was unable to climb up to the top of the ballast mountain. The ballast for extra heap is compacted from the middle of the pile by the compaction plate 4, and the ballast for extra heap that protrudes from the compaction plate 4 cannot be compacted, so the ballast for extra heap is moved to the sleeper. There was a problem in that it was not possible to sufficiently supply and compact the area near the longitudinal ends of the concrete.

"Means for Solving the Problems" The present invention has been made to solve the above-mentioned problems, and the details thereof will be explained below using FIG. 1 corresponding to an embodiment.

As shown in FIG. 1, a parallel link mechanism 20 is provided, consisting of two parallel links 18 and 19, each of which is rotatably mounted on the trolley 3 at its upper end.
When the compacting device 17 having the compacting plate 4 and the vibration device 5 is rotatably attached to the lower ends of the links 18 and 19, the compacting plate 4 is used to perform the work of the cart 3 as indicated by the arrow 24. Make it tilt upward with respect to the direction of time. Then, the rod 22 side of the setting storage hydraulic cylinder 23, which is rotatably mounted on the trolley 3 on the cylinder 21 side, is connected to one of the links 18 and 19, for example, the link 18.
The setting storage hydraulic cylinder 23 lowers the compacting device 17 via the parallel link mechanism 20 onto the ballast of the track bed near both ends of the sleepers in the longitudinal direction during work. When transporting the vehicle, it is raised above the ballast and kept within the limits of the vehicle. In this case, the level difference between the ballast surface compacted by the compacting device 17 and the ballast surface that has not yet been compacted is small, and the compacting plate 4 of the compacting device 17 is When using the ballast compactor 16 on a trackbed where the compacting device 17 can easily ride from a compacted ballast surface to an uncompacted ballast surface without having to tilt the compacting device 17 upward, Compacting plate 4
The parallel link mechanism 20 may be configured so that the angle is horizontal.

"Operation" Therefore, when the ballast compactor 16 is working, the compacting device 17 moves in the direction of the arrow 24 together with the trolley 3 while compacting the ballast on the roadbed near both longitudinal ends of the sleepers. Even if the device 17 descends to follow the surface of the compacted and sinking ballast and creates a large step between the surface of the compacted ballast and the surface of the uncompacted ballast, the compaction continues. Even if extra ballast is piled up on a track bed that is not covered, the compaction plate 4 of the compacting device 17 is inclined upward with respect to the direction of movement of the trolley 3 during work, so it cannot be used as in the conventional method. The tip of the compaction plate 4 easily climbs onto the surface of the uncompacted ballast or extra ballast without protruding into the uncompacted ballast or extra ballast, and the tip ends of the compaction plate 4 easily ride on the surface of the uncompacted ballast or extra ballast, and the tip ends of the compaction plate 4 do not penetrate into the uncompacted ballast or extra ballast. Compaction can be achieved by sufficiently supplying ballast for extra heap near the ends of the concrete.

"Embodiment" An embodiment of the present invention will be described below in detail based on the drawings.

It has a power unit 13 that operates a setting storage hydraulic cylinder 23, etc., and an operation panel 14.

Note that the parallel link mechanism 20 shown in FIG.
The lower ends of the links 18 and 19 are arranged such that the mounting position of the upper end of the front link 18 on the trolley 3 is located above the mounting position of the upper end of the rear link 19 on the trolley 3 by a predetermined amount e. is connected to the compacting device 17, and its compaction plate 4 is inclined upward with respect to the direction of movement of the trolley 3 during operation, but this is not limited to this embodiment. . That is, the mounting positions of the upper ends of the equal-length links 18 and 19 on the trolley 3 are on the same horizontal line, and the mounting position of the compacting device 17 to the lower end of the link 18 is adjusted to the lower end of the link 19. The links 18 and 19 may be positioned above the mounting position on the trolley 3, or the link 18 may be made shorter than the link 19 so that the mounting positions on the trolley 3 at the upper ends of the links 18 and 19 are on the same horizontal line. , link 1
It is obvious that the same purpose can be achieved by attaching the compacting device 17 to the lower end portions of the parts 8 and 19.

Further, in the embodiment shown in FIG. 1, a power device 13 for operating the compacting device 17 and the setting storage hydraulic cylinder 23 is provided on the trolley 3,
The running of the bogie 3 is shown as being pulled by other track maintenance work vehicles such as multiple tie tampers and motor power, but this is also not limited to this embodiment, and a running device is provided to drive the bogie 3. The device 13 may allow the ballast compactor 16 to run on its own, or the power device 13 may be removed and power may be supplied from another track maintenance vehicle towing the ballast compactor 16.

Therefore, when working on the ballast compactor 16, the power unit 13 is operated, and the setting storage hydraulic cylinder 23 is operated using the operation panel 14.
Via the parallel link mechanism 20, the compacting device 17 is lowered onto the ballast 7 of the trackbed near both ends of the sleeper 6 in the longitudinal direction, and then the operation panel 14

When traveling on the rail 2 in the direction of the arrow 24, the compacting device 17 moves together with the truck 3 on the ballast 7 in the direction of the arrow 24 while compacting the ballast. And the compacting device 17
If the surface of the ballast follows the surface of the compacted and settled ballast and descends, creating a large step between the surface of the compacted ballast and the surface of the uncompacted ballast, Even if extra ballast is piled up on the track bed, the compaction plate 4 of the compacting device 17 is inclined upward with respect to the direction of movement of the ballast compactor 16 during operation, so compaction cannot be performed as in the conventional method. The compacting device prevents the tip of the solid plate 4 from penetrating into uncompacted ballast or extra ballast and interrupting the compaction work, or compacting without sufficiently replenishing extra ballast. 17 can easily climb onto the surface of uncompacted ballast or extra ballast, and can continue the compaction work of the ballast near both ends of the sleeper in the longitudinal direction. It is possible to compact the sleepers by sufficiently supplying them near the longitudinal ends of the sleepers.

"Effects of the Invention" As described above, the ballast compactor of the present invention rotates the upper end of each link of a parallel link mechanism consisting of two parallel links on a bogie that can run on the rails of a railway track. The compacting device is rotatably attached to the lower end of each link, and the compacting device is attached so that the compacting plate is inclined upward with respect to the direction of movement of the trolley during operation.
Even if there is a large step difference between the surface of the ballast compacted by the compacting equipment and the surface of the uncompacted ballast during operation, or near the longitudinal ends of the sleepers on the uncompacted track bed. Even if the overfill ballast is heaped on top of the ballast, the compacting equipment can easily climb onto the surface of the uncompacted or overfill ballast and remove the ballast near the longitudinal ends of the sleepers. It is possible to continue the compaction work, and it also has effects such as being able to sufficiently supply ballast for extra heap near the ends of the sleepers in the longitudinal direction and compacting them.
