Abstract

PURPOSE:To make uniform compaction of ballast possible regardless of variation in distance between sleepers by thrusting compacting heads into the ballasts, holding a sleeper in between, with adjustment made to the distance between the front and the rear compacting heads, and by making compaction with shakers operated. CONSTITUTION:For an inner compactor 30 of a compactor main body 10, an elevator bed 15, capable of ascending and descending, is provided to a fixing platform 13 placed on a bed frame 11 of the compactor main body 10, and shakers 19 and compacting heads 21 and 21 are provided through a vibration isolator 17 to the underside of the bed 15. When making compaction, a rod of a cylinder 16 for elevating motion is extended, allowing the elevator bed 15 attached to the front of the cylinder rod to descend to ballasts, and the compacting heads 21 and 21 are made thereby to thrust into the ballasts, holding a sleeper in between. The compacting heads 21 and 21 vibrate in the ballasts with vibration produced by operation of the shakers 19, and thereby the ballasts on lateral sides of the sleeper are compacted. When necessary, the work may be executed with the distance between the front and the rear compacting heads 21 and 21 extended to meet the distance between the sleepers. Thereby uniform compaction of the ballasts can be made even though the distance between the sleepers varies.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a compactor device for track maintenance work, and particularly to a compactor device for effectively compacting ballast laid on a track bed. Related to equipment.

(Prior technology) A compactor device for compacting the ballast laid on the track bed is an essential device for maintaining the well-aligned track condition, and various types have been proposed in the past. has been done. In particular, in order to simultaneously compact the ballast laid before and after the sleepers (between the sleepers) and the ballast laid on the end side of the sleepers, an inner compactor and an outer compactor are attached to the main body of the machine. Compactor equipment equipped with this is widely used due to its excellent workability.

Conventionally, such a compactor device was known to have the compactor installed against the main body of the device so that the inner and outer compactors were placed on the same sleeper, but this type of compactor was installed between the vehicle limit and the rail. It was a narrow gauge (1076 rnm) device with plenty of room for installing an external compactor. However, recently, standard gauge (14
35 mm), a compactor device equipped with an inner and outer compactor is also required. In compactor devices for standard piles like this, the inner compactor needs to be installed on the outer band of the device body in line with the rail position of the standard gauge, so the dimension between the vehicle limit and the inner compactor becomes narrower. , it becomes difficult to install the outer compactor outside the inner compactor in the same sleeper. Therefore, by installing the inner and outer compactors in the main body of the device with their front and back (in the rail length direction) shifted state, the , 2 is a sleeper that supports this, 3a and 3b are front and rear compact stands inserted on both sides of the sleeper 2, and 4 is an outer compactor that compacts the ballast at the end of the sleeper 2. In addition, in the figure, the front and rear compact stands 3
Two units a and 3b are provided with the rail 1 in between, and the inner compactor is constituted by four compact units as a whole. Further, these inner compactors and the outer compactor 4 are respectively provided on the left and right sides of the compactor device main body (not shown), corresponding to the left and right rails.

In such a compactor device, the ballast before and after the sleeper 2 is compacted by first inserting the front and rear compacting tables 3a and 3b into both sides of the first sleeper ■ for the inner compactor, as shown in ■ in the figure. , Compact the ballast between the sleepers. At the same time, regarding the outer compactor 4 installed at a position away from the inner compactor, this is connected to the sleeper
By crimping and vibrating the track bed on the outside of the end of another sleeper located at a distance from the ballast, the ballast in that area is compacted and lateral resistance against the sleeper is ensured.

Next, the main body of the apparatus is run, and at the position of the next sleeper ■ that is one sleeper ahead of the sleeper ■, the second sleeper is removed between the sleepers by the compactor I and the stands 3a and 3b of the inner compactor, sandwiching this sleeper ■. At the same time as compacting the ballast, the outer compactor 4 starts compacting the ends of the sleepers at the position marked ■, which is a distance corresponding to the distance traveled by the device (two sleepers) from the first compactor position. I do. In the same manner, the compacting work is repeated for every other sleeper.

(Problems to be Solved by the Invention) However, the conventional compactor device as described in Section 1 has the following two major problems.

The first problem is related to the inner compactor.
Since the distance b was set constant, the distance between the sleepers and the compact stands 3a, 3b may vary depending on the distance between the sleepers. That is, in FIG. 6, during the first compacting work, although the distance L1 between the sleeper ■ and the compacting tables 3a and 3b inserted on both sides thereof is equal,
The second compactor work is performed with one sleeper ■ placed between them, so the sleeper sandwiched between these sleepers ■■ is the sleeper and the compact stand 3a.

3b will be different, making it impossible to evenly compact the sides of each sleeper. In particular, when the distance between the compact stand and the railroad ties becomes large, effective compaction and consolidation become impossible. However, the spacing between the sleepers on an actual track varies depending on the section where the sleepers are arranged differently, such as a curved section, and the type of sleepers. The distance between the compact stand and the compact stand was not constant, making it difficult to perform even and effective compaction.

The second problem concerns the outer compactor. The outer compactor 4 is configured to compact the ends of multiple sleepers at once, but in that case, the first compaction position At the second compaction position (3), the end of the outer compactor 4 is oriented to the east so that effective compaction can be performed. In particular, by locating the overlapping portion of the outer compactor 4 at the end of the sleeper and compacting the ballast at the end of the sleeper twice, the lateral resistance force of the sleeper increases. However, as mentioned above, the spacing between the sleepers is not always constant, so depending on the spacing between the sleepers, it is not possible to perform compacting work with the outer compactor 4 overlapped at the ends of the sleepers, as shown in Figure 6. , it was not possible to carry out effective compaction.

The present invention was proposed in order to solve the problems of the prior art as described above, and the first purpose is to enable uniform and effective compaction of the sides of the sleepers even if the spacing between the sleepers is different. An object of the present invention is to provide a compactor device including a compactor.

A second object of the present invention is to effectively compact the ends of the sleepers by ensuring that the position where the outer compactor performs the second compaction is always at the end of the sleepers even if the spacing between the sleepers is different. An object of the present invention is to provide a compactor device equipped with an outer compactor.

Configuration 1 is characterized by providing front and rear compact stands that are inserted on both sides, and providing a compact stand moving mechanism that makes the interval between the front and rear compact stands variable along the length direction of the rail. .

Further, the invention of claim 2 provides a compactor device for track maintenance which is provided with an outer compactor for compacting the ballast at the end of the sleeper with respect to the device main body, in which the mounting position of the outer compactor with respect to the device main body is adjusted along the length direction of the rail.

A vibrating portion 43 is provided on the back surface of the device.

The compactor device of this embodiment has the above-mentioned configuration, and its effects will be explained next.

First, the inner compactor 30 will be described. By extending the rod of the lifting cylinder 16, the inner compactor 30 lowers the lifting platform 15 at the tip toward the track bed. 21.2
1 into the ballast of the trackbed, sandwiching the sleepers. Then, by driving the vibrator 19, the compact stand 21.21 is vibrated within the ballast, and the ballast is compacted against the side surface of the sleeper.

By the way, the distance between the sleepers is 21.21
If the front and rear compact stands 21.21 cannot be located on the center line between the sleepers in the initially set state, the distance between the front and rear compact stands 21, 21 will be adjusted according to the spacing between the sleepers. Adjust. That is, by driving the cylinder 26 shown in the plan view of FIG. 3 to press or pull the movable side bearing 23 against the fixed side bearing 22 in the center, the distance between the front and rear compact stands 21, 21 is adjusted. . In addition, the compact stand 21.
The movement and stopping operations of 21 are controlled by a switch 28 provided on the support base 18 detecting the cam 27 of the moving side bearing 23.

In this way, even if the spacing between the sleepers differs depending on the condition of the track such as a curved section or the type of sleepers, the spacing between the front and rear compact stands 21 can be adjusted according to the sleeper spacing, as shown in Fig. 5. As shown in the plan view, it is possible to compact the ballast by inserting a compact stand between the sleepers, so that the ballast can be compacted evenly on the sides of each sleeper. . Furthermore, since the distance between a particular sleeper and the compact stand will not be too great, there is no fear that the compacting force will be insufficient due to the sleeper.

Next, regarding the outer compactor 50, the movable table 3 is supported via the guide shaft 32 with respect to the pedestal of the apparatus main body 1.
4 is stopped at a predetermined position, lift cylinder 4

This compaction of the ballast by the outer compactor 50 is performed in synchronization with the compaction work of the inner compactor, which is performed for every other sleeper, as in the conventional type. The first compaction ■ of the outer compactor is carried out corresponding to the working position ■ of the inner compactor, and the second compaction ■ of the outer compactor is carried out corresponding to the second working position ■ of the inner compactor. . Then, during the first compaction and second compaction of the outer compactor, the ends of the compactor section 42 overlap, and the ballast in that area is compacted twice. When the overlapping part does not come to the end of the sleepers due to the spacing of the sleepers as in the conventional type, use the longitudinal movement cylinder 35 in FIG.
is driven, the entire movable table 34 is moved back and forth with respect to the frame of the apparatus main body 10, and the end of the compactor section 42 supported by the movable table is adjusted to be located at the end of the sleeper. Note that this adjustment amount is detected by a cam 37 provided on the slide bearing portion of the movable table 34 and a switch 36 provided near the rotation axis.

In this way, no matter what the position of the machine body that stops at every other sleeper during the work of the inner compactor is in relation to the sleeper spacing, the attachment position of the outer compactor to the machine body, that is, the inner compactor, can be adjusted. By doing this, it becomes possible to compact the ends of the sleepers twice using an external compactor,
It is possible to improve the lateral movement resistance of the sleepers.

[Other Embodiments] As described above, the invention of claim 1 allows the interval between the front and rear compactors constituting the inner compactor to be adjustable, but it is not necessarily limited to the above embodiments, and the outer compactor can be adjusted. It can also be used as a compactor device for a simple inner compactor without a compactor.

Furthermore, since the invention of claim 1 is characterized in that the attachment position of the outer compactor with respect to the apparatus body is variable, the apparatus does not have an inner compactor or a tamping device is provided in place of the inner compactor. It is also applicable to compactor devices.

Further, the guide and support means for the front and rear compacting tables or the guide and support means for the outer compactor may have a configuration other than that shown in the drawings, and a hydraulic cylinder or motor may be freely used as the drive means.

[Effects of the Invention] As described above, according to the present invention, the front and rear compacting tables and the outer compactor are configured to be movable along the length direction of the rail relative to the apparatus main body in accordance with the sleeper spacing. It is possible to provide a track maintenance compactor device that can evenly and effectively compact ballast even if the sleeper intervals are different.
