Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides the following advantages:
This compactor device is used to compact the ballast near both lengthwise ends of sleepers. It is especially attached to a running vehicle body and performs continuous compaction work on the track bed. Furthermore, it is used automatically on curved sections of rails. This invention relates to a compactor device equipped with a position adjustment function for horizontally swinging the compactor.

[Prior art] Track leveling involves lifting the rails using a rail lifting device, then tamping the ballast at the bottom of the sleepers using a tamping device to adjust the height and level of the track. be. Furthermore, lining adjustment involves pushing the rail sideways with a cylinder for straightening the rail to straighten the rail. After such track leveling and lining adjustment, the ballast scattered during tamping is on the sleepers, so this is removed from the sleepers with a sweeper, and then in order to prevent the lateral movement resistance of the sleepers from decreasing. It is necessary to compact the track bed by compacting the ballast near both longitudinal ends of the sleepers using a compactor. In this case, the ballast on the sleepers may be removed using a sweeper after compaction of the track bed.

Conventionally, this work of compacting the roadbed was carried out by workers using rammers, etc., but compaction work using rammers, etc. was performed manually by operating the equipment, so a dedicated The drawback was that it required a large number of workers and was inefficient. In addition, compaction work using a rammer or the like is accompanied by intense vibration and noise, which places a heavy burden on the workers and may cause problems such as health problems.

For this reason, the applicant installed a compactor via a support frame on the rear of the body of a moving track maintenance vehicle, such as a ballast sweeper, thereby reducing the burden on the workers. We proposed a traveling compactor that can efficiently compact roadbeds. That is, when this type of compactor is used for forwarding, the compactor is pulled up to a fixed position by a hydraulic cylinder and held, lowered onto the ballast at the work point, and the vibration motor is used to vibrate the compactor, causing the compactor to vibrate on the roadbed surface. This method continuously compacts the ballast on the roadbed surface by compacting the ballast or by driving the vehicle at low speed while vibrating the compactor.

Therefore, this type of compactor is highly effective in improving work efficiency and reducing the burden on workers.

However, the compactor installed at the rear of the vehicle body as described above has caused the following problems when passing through curved sections of the rail.

That is, when the car body with the compactor attached comes to the curved part of the rail, if the compactor is fixed to the car body via a support frame, or if it can move left and right with respect to the car body, due to inertia, In the end, the longitudinal center of the car body and the center of the axis where the compactor should work were misaligned, making it impossible to effectively compact the ballast near both longitudinal ends of the sleepers, which became a major problem. was.

[Problems to be Solved by the Invention] The present invention was proposed in order to solve the problems of the prior art as described above. The system detects the deviation between the axis and the center of the axis where the work is to be performed by the compactor, and then swings the compactor horizontally by the same amount as this deviation, correcting the position so that effective track bed compaction work can be performed even on curved sections of the rail. An object of the present invention is to provide a compactor device with functions.

[Means for Solving the Problems] The compactor device of the present invention having a position adjustment function is provided with a bogie below the car body that is integral with the car body and can run on rails, and the car body and the bogie are connected to each other. By installing a displacement measuring device between them, and further installing a control device that receives the signal from this displacement measuring device, and a driving device that swings the compactor horizontally by the measured displacement amount according to the instructions of this control device. ,
This enables effective compaction work even on curved sections of the rail.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

1 and 2, a rotation shaft 2 extending vertically is attached to the rear of a vehicle body 1, and below this rotation shaft 2, a support frame 3 and a guide support frame 3' are attached.
is attached at one end so as to be rotatable up and down, and can be moved up and down by a storage/setting hydraulic cylinder 4 provided above. Further, a compactor 5 is swingably attached to the other ends of the support frame 3 and the guide support frame 3'. This compactor 5 consists of upper and lower substrates 5a, 5b and a vibration part 5c that is driven by a swing motor (not shown) provided on the lower board 5b, and vibrates the lower board 5b via the vibration part 5c. It's becoming like that. Also,
The upper and lower substrates 5a, 5b are connected via a vibration isolating member 5d. Although FIGS. 1 and 2 show only one of the pair of left and right compactors 5 provided in the longitudinal direction of the rail, the other compactor 5 having the same configuration is similarly provided. Further, the left and right compactors 5 are arranged to be located at a constant equal distance from the end of the sleeper, respectively, when the vehicle body 1 is on a straight section of the rail.

On the other hand, as shown in FIG. 3, below the vehicle body 1,
A bogie 6 that can run on rails and runs simultaneously with the car body 1 is provided, and the car body 1 and the bogie 6 include:
Levers 7 and 8 are installed in the vertical direction, respectively, and a displacement measuring device 9 is installed between these levers. Furthermore, the support frames 3 of the left and right compactors 5 are equipped with
A hydraulic cylinder 10 is provided to rotate this left and right, and the support frame 3 is provided with a measuring device 11 that detects the amount of rotation. The control device 12 inputs the signals of the displacement measuring device 9 and the measuring device 11, and controls the measuring device 1.
A hydraulic cylinder 10 serving as a drive device is operated to rotate the support frame 3 until the output of the displacement measuring device 1 becomes equal to the output of the displacement measuring device 9, and the compactor 5 attached to the tip thereof is moved.

The operation of the compactor device of the present invention having the above configuration is as follows.

That is, in the curved part of the rail, the center of the longitudinal direction of the car body 1 does not coincide with the center between the axes of the compaction work section, and since the bogie 6 is free with respect to the car body 1, there is a gap between the two. A positional shift occurs, the amount of displacement is measured by the displacement measuring device 9, and a signal is output to the control device 12. Then, the control device 12
gives an instruction to the solenoid valve (not shown) of the directional control valve to operate the hydraulic cylinder 10, and as a result, the support frame 3 rotates, the compactor 5 moves, and the amount of movement is measured by the measuring device 11, It is output to the control device 12. The control device 12 controls the compactor 5 so that the amount of displacement measured by the displacement measuring device 9 and measuring device 11 is the same.
In order to move the compactor, the compactor is moved by the amount of deviation between the longitudinal center of the car body and the center of the shaft in the curved part of the rail, so the compactor does not interfere with sleepers, etc., which was particularly difficult in the past. Effective compaction work can be performed on curved sections of rails. Further, in this embodiment, two measuring instruments, a displacement measuring instrument 9 and a measuring instrument 11, are provided. Of these, the displacement measuring device 9 detects the amount of displacement of the vehicle body 1 and the truck 6 from the amount of movement of the levers 7 and 8,
On the other hand, the measuring device 11 detects the amount of displacement of the compactor 5 from the amount of rotation of the support frame 3. These measuring instruments 9,1
1 only measures the amount of displacement of the member on which the measuring device itself is provided, so it is extremely easy to simplify its configuration.

Generally, around compact devices with large vibrations,
When a precision measuring instrument is used, there is a high risk that the measuring instrument will break down. However, since the measuring instruments 9 and 11 in this embodiment can easily be simplified in configuration, they are less likely to fail and have high reliability as measuring instruments. As a result, control device 1
2 can exhibit excellent performance, and the hydraulic cylinder 10 operated by the control device 12 can ensure high operability. the result,
The workability of compaction work using the compactor 5 has been greatly improved.

Note that the present invention is not limited to the above-mentioned embodiments; for example, a pneumatic cylinder, various motors, etc. can be used as a drive device for moving the compactor 5, and such a drive device can be directly connected to the compactor 5. A configuration in which they are connected is also possible.

[Effects of the Invention] As explained above, the present invention has a simple configuration in which the displacement between the longitudinal center of the vehicle body and the center between the shafts is measured and the compactor is moved by the same amount as the displacement. Thanks to improvements, the compactor does not interfere with sleepers even on curved sections of the rail.
It is possible to provide a compactor device with an excellent position adjustment function that enables effective compaction work, and its effects are extremely large. In addition, in the present invention, 2
Since two measuring instruments are provided, the configuration of the measuring instrument itself can be simplified, and the reliability of the measuring instrument and the workability of compaction work have been greatly improved.
