Description

[Detailed Description of the Invention] The present invention relates to a tamping position setting device for a track straightening machine that tamps a plurality of sleepers by sequentially moving a set of tamping mechanisms for each sleeper.

Recently, in order to improve the work efficiency of a track straightening machine, a set of tamping mechanisms are moved sequentially for each sleeper to tamp a plurality of sleepers, and when the tamping of the plurality of sleepers is completed, the A mobile track straightening machine has been proposed in which the tamping mechanism is returned to the initial tamping start position, the track straightening machine is moved between a plurality of sleepers to be tamped, and the same operations as described above are repeated.

Compared to a conventional fixed track straightening machine, which has a fixed set of tamping mechanisms, this moving track straightening machine has only one sleeper.
Since there is no need to move or stop the track straightening machine for each book, it has the advantage of reducing power consumption and improving work efficiency.It also has multiple sets of fixed tamping mechanisms, so multiple tamping machines can be used at the same time. Compared to the conventional double track straightening machine that compacts sleepers, it has a simpler structure and is easier to operate.
Moreover, while the dual track straightening machine can only be used in sections where the sleeper spacing is relatively uniform, the mobile track straightening machine has the advantage of being able to be used regardless of the sleeper spacing.

In addition, in order to set the tamping position of the conventional track straightener, a thin rubber band is placed at the center of the crossbeam of the track straightener's frame, aligned with the center of the tamping mechanism, and suspended above the sleeper. Alternatively, a metal indicator board is installed, and the operator visually aligns the center of the tamping mechanism and the center of the width of the sleeper (hereinafter abbreviated as the center of the sleeper) using this indicator board as a reference. The main aircraft was moving back and forth.

However, since the indicator board cannot be brought into contact with the sleeper surface violating the construction limits, a large gap is created between the tip of the indicator board and the top surface of the sleeper, and this gap varies depending on the type of rail. It takes great skill to visually align the center of the tamping mechanism with the center of the sleeper using the board as a reference, and inexperienced people must repeat trial and error, and it takes time to set the tamping position. There was a drawback that it took a long time.

Therefore, if the tamping position is set using this method, the advantage of improving the work efficiency of the mobile track straightening machine will be diminished.

Therefore, in order to further improve the work efficiency of mobile track straightening machines, a tamping position setting device is required that can accurately, quickly, and easily align the center of the moving tamping mechanism with the center of the sleepers. becomes.

The present invention has been developed in view of the above points, and when the mobile track straightening machine moves between multiple sleepers to be tamped and stops, the first step is to set the tamping position of the first sleeper.
While the tamping position setting device and the tamping mechanism are tamping the sleepers, a second tamping position setting unit that sets the tamping position of the sleeper to be tamped next is used to accurately and quickly set the tamping position of the sleeper. The present invention also provides a tamping position setting device that can be easily set.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of a main part of a mobile track straightening machine equipped with a tamping position setting device according to an embodiment of the present invention, and FIG. 2 is a view taken in the direction of arrow A in FIG. 1.

In the figure, a mobile track straightening machine 2 that can run on a rail 1 has a set of tamping mechanisms 4 to which a tamping tool 3 is attached.

The tamping mechanism 4 is a frame 5 of the mobile track straightening machine 2.
It moves in the longitudinal direction along the guide frame 8 on the guide 6 provided horizontally in the longitudinal direction above, by the operation of the hydraulic cylinder 7 for lateral movement, and along the guide frame 10 by the operation of the hydraulic cylinder 9 for raising and lowering. It is configured to move up and down.

Therefore, the mobile track straightening machine 2 is to be tamped between the plurality of sleepers T3. T2. TI..., the mobile track straightening machine 2 is stopped at a position where the center B-B of the tamping mechanism 4 coincides with the center of the sleeper T1, and the lifting hydraulic cylinder 9 is operated. , the tamping mechanism 4 is lowered, and the vibrating tamping tool 3 is pushed into the road bed gravel 11 to compact the sleeper T1. When the compaction is finished, the lifting hydraulic cylinder 9 is operated to lower the tamping mechanism 4. and lift the tamping tool 3 from the roadbed gravel into the air.

Next, the lateral movement hydraulic cylinder 7 is operated to move the tamping mechanism 4 along the guide 6 and the guide frame 8 in the direction of the sleeper T2, so that the center B-B of the tamping mechanism 4 moves toward the sleeper T2.
Stop the tamping mechanism 4 at a position that coincides with the center of
The sleeper T2 is compacted in the same manner as the sleeper T1.

Thereafter, the sleepers T3... can be compacted in the same manner.

In this way, when the tamping of a predetermined plurality of sleepers is completed, the tamping mechanism 4 is moved to the position of the first tamped sleeper T1, and the mobile track straightening machine 2 is moved to the position of the plurality of sleepers to be further tamped. The track adjustment work is continued by moving between the sleepers, moving between the sleepers described above, and repeating the tamping work described above.

The tamping position setting device of the present invention is attached to such a mobile track straightening machine 2, and the first tamping position setting section and the second tamping position setting section are used to set a plurality of sleepers TI, T.
2. The tamping position of the tamping mechanism 4 relative to T3 is set accurately, quickly and easily, and the tamping mechanism 4 is stopped at that position.

1 and 2, a tamping position setting device 12, which is an embodiment of the present invention, includes a first tamping position setting section 13 and a second tamping position setting device 14.

The first tamping position setting unit 13 includes a first indicator 15, a first detector 16, and a first detector 17. The first indicator 15 and the first detector 16 are attached to the frame 5 of the mobile track straightening machine 2. , are attached at regular intervals in the direction of movement of the tamping mechanism 4, and the first detector 17 is attached to the tamping mechanism 4 so as to engage with the first sensing body 16, and the first detector 17 is attached to the tamping mechanism 4 so as to engage with the first sensing body 16, and the first detector 17 is attached to the tamping mechanism 4 at a constant interval in the direction of movement of the tamping mechanism 4. The center distance between and the first detector 17 is
It is equal to the center distance between the first indicator 15 and the first sensing body 16.

Moreover, when the first sensing body 16 and the first detector 17 engage,
A signal is emitted from the first detector 17, and a control device (not shown)
The damping mechanism 4 is stopped via.

The second tamping position setting section 14 is controlled by a second indicator 18, a second detector 19, a second detector 20, and a chain mechanism 21.

The chain mechanism 21 is a frame 5 of the mobile track straightening machine 2.
The tamping mechanism 4 is disposed parallel to the direction of movement and separates from the guide culm 8 and a chain 25 driven by the prime mover 22 via splot wheels 23,24.

The second indicator 18 and the second sensing body 19 are attached to the chain 25 at a constant interval, and the second sensing body 20 moves with the chain 25 while engaging with the guide culm 8.
9, and the distance between the center B-B of the tamping mechanism 4 and the second detector 20 is equal to the center distance between the second indicator 18 and the second detector 19. It is.

Further, when the second sensing body 19 and the second detector 20 engage,
A signal is generated from the second detector 20 and the tamping mechanism 4 is stopped via the control device.

The tamping position setting device 12 of the present invention has the above-described configuration, and its operation will be described below.

First, the tamping mechanism 4 is moved to the first tamping position setting section 1.
When the tamping mechanism 4 is moved to position 3, the first detector 17 engages with the first detection body 16, and the tamping mechanism 4 stops at a position where the center of the first index and the center B--B of the tamping mechanism 4 coincide.

In this state, when the track straightening machine 2 is moved between the plurality of sleepers to be installed and stopped at a position that coincides with the center of the first index 15, the center of the tamping mechanism 4 is moved. B
-B coincides with the center of the sleeper T1, and the correct tamping position of the tamping mechanism 4 with respect to the sleeper T1 is set.

Therefore, the lifting hydraulic cylinder 9 is operated to lower the tamping mechanism 4, and the tamping tool 3 is moved to the roadbed gravel 1.
1 and prepare and set sleeper T1.

In the meantime, the prime mover 22 of the chain mechanism 21 is rotated to move the second indicator 18 and the second detection body 19 of the second tamping position setting section 14 in the direction of the sleeper T2, and the second indicator 1
At the position where the center of 8 coincides with the center of sleeper T2,
, when the second indicator 18 and the second sensing body 19 are stopped, the damping position of the tamping mechanism 4 with respect to the sleeper T2 is set.

On the other hand, when the laying of the sleeper T1 is completed, the lifting hydraulic cylinder 9 is operated to raise the tamping mechanism 4, the tamping tool 3 is pulled up from the road bed gravel 11, and the lateral movement hydraulic cylinder 7 is operated. Tamping mechanism 4 to sleeper T2
When the tamping mechanism 4 is moved in the direction of Stop at tamping position.

Therefore, in the same manner as in the case of the sleeper T1, while the tamping mechanism 4 is manufacturing and setting the sleeper T2, the second indicator 18 and the second sensing body 19 of the second tamping position setting section 14 are connected to the chain mechanism. 21 is driven to move in the direction of the sleeper T3, and the second indicator 18 and the second sensing body 19 are stopped at a position where the center of the second indicator 18 coincides with the center of the sleeper T3.
The tamping position of the tamping mechanism 4 with respect to the sleeper T3 is set.

In the above manner, while the tamping mechanism 4 is preparing and placing one sleeper, the second tamping position setting section 14 repeats the operation of setting the tamping position of the next sleeper, thereby producing a plurality of sleepers. TI, T2. When the setting of T3... is completed, the tamping mechanism 4 is raised and the first sleeper T4 set by the first tamping installation part 13 is
tamping position.

Next, the track straightening machine 2 is further moved by the number of sleepers to be manufactured, and the above-mentioned plurality of sleepers TI, T2. T
By repeating the same operation as for 3..., tamping work can be performed continuously.

As an indicator of the tamping position setting device according to the embodiment of the present invention described above, a light source such as an indicator plate or a lamp and a condensing lens are built into a thin rubber or metal. An image of a light source made on the top surface of the image may also be used.

However, as described above, the indicator board causes parallax due to the distance between the tip of the indicator board and the top surface of the sleeper, and skill is required to set the tamping position.

On the other hand, the image of the light source of the projector is created directly on the upper surface of the sleeper, and therefore no parallax occurs, so the tamping position can be set accurately, quickly and easily without requiring any skill.

In particular, a lamp is used as the light source of the projector, and the second index of the first index is
By adjusting the focus of the index projector and creating different images on the upper surface of the sleeper, it is convenient to be able to distinguish between the index of the first tamping position setting section and the index of the second tamping position setting section.

Alternatively, the discrimination may be made using colored lamps of different colors.

Further, a limit switch, a phototube, a proximity switch, or the like may be used as the detector.

As the detection object, a cam is used for a limit switch, a light source such as a lamp is used for a phototube, and a detection metal fitting is used for a proximity switch.

Note that FIGS. 1 and 2, which show an embodiment of the present invention, show a case where an image of a light source of a projector is used as an index, a proximity switch is used as a detector, and a detection metal fitting is used as a detection object.

As described above, the damping position setting device of the present invention tamps the center of the first index by the first tamping position setting part when the mobile track straightening machine moves between a plurality of sleepers for tamping. The tamping position of the first sleeper is set to match the center of the first sleeper, and while the tamping mechanism is tamping one sleeper, the second tamping position setting section sets the center of the second indicator to the next The tamping position of the next sleeper can be set simply by aligning the tamping mechanism with the center of the tamping mechanism, and the tamping mechanism is automatically stopped when the detector installed in the tamping mechanism engages with the detection body.
The tamping position of the tamping mechanism can be set accurately, quickly and easily.

In addition, one set of the second tamping position setting section is provided for each sleeper excluding the first sleeper among the plurality of sleepers to be tamped, and the tamping mechanism While one sleeper is being tamped, the tamping positions of the remaining sleepers can be set at the same time.

For this reason, there are great effects such as being able to perform track adjustment work efficiently.
