Description

[0001]
BACKGROUND OF THE INVENTION
The present invention has a tamping unit provided with a plurality of tamping tools corresponding to the inside and outside of a track, and performs a work of fixing ballast on a track with each tamping tool (hereinafter referred to as a multy). The present invention relates to a tamping device that detects a track condition immediately before performing a tamping operation and automatically controls each tamping tool based on the information.
[0002]
[Prior art]
Multai is a track maintenance machine that lifts the sleepers to be tamped by the clamp device together with the track, and in that state, the ballast on the track is secured by the tamping tool. Usually, before and after the sleepers to be tamped, a total of twelve places, one inside each of a set of two tracks and two outside, are consolidated together.
[0003]
However, the tamping tool and the incidental equipment interfere with each other and cannot be compacted at the part where the track is branched, or at the railway crossing or where the incidental equipment such as a signal cable is provided. For this reason, a ground worker who confirms the position of the tamping tool on the left and right sides of the martai and an in-vehicle operator who individually operates the tamping tools on the left and right sides in the martai vehicle are required, and a total of four workers are tamping. I was doing the consolidation while checking the track conditions at the site. Moreover, in order to perform the work accurately, the in-vehicle operator has to operate each tamping tool as instructed by the ground operator, and the cooperation between the ground operator and the in-vehicle operator is also important.
[0004]
This method of relying on ground workers and in-vehicle operators is not only inefficient, but at night and in the rain, ground workers and in-vehicle operators are also very sensitive to safety and operational errors. Using nerves, it was very hard work. Especially on the Shinkansen, it was only night work, and physical and mental fatigue was extremely large. In addition, since the tracks crossed around the turnouts, the fastening devices for the tracks, sleepers, etc. were installed in a complicated manner, and there was a ballast, so the scaffolding was very bad and it was a dangerous place. Furthermore, the compacting work with the tamping tool has problems such as dust and noise, and is not a favorable working environment from the viewpoint of health for ground workers and in-vehicle operators. Furthermore, if there is a confirmation error or an operation error, the train operation is hindered, and there is a problem that it causes great trouble for ordinary train passengers.
[0005]
For this reason, conventionally, the track condition is investigated in advance, the data is recorded on a recording medium such as a floppy disk, and when performing the tamping work, the recording medium is taken out and the tamping tool is based on the recorded information. An automatic tamping method has been devised.
[0006]
[Problems to be solved by the invention]
However, despite the fact that the work of compacting the place where the branching device is installed is less frequent once a year, the data includes the shape of the branching device, the difference in location, Considering the number of installations, etc., there was a huge amount of data, and there was a hassle of having to consider how to manage the data. In other words, when working with different data recording media taken out, there was a problem of damaging the branching device, etc., and it was necessary to give sufficient consideration to prevent mistakes in data retrieval and storage. .
[0007]
The branching unit is also a place that receives a great impact when passing through the train, and may be partially reworked for track maintenance. In addition, track conditions, including incidental equipment related to other tracks other than turnouts, may be improved one after another by reviewing safety standards and track maintenance. In such a case, there is a problem that the original data cannot be used and automatic compaction work cannot be performed.
[0008]
[Means for Solving the Problems]
The present invention has been improved and removed in view of the conventional problems described above, and each time a tamping operation is performed, the line condition or the like is detected immediately before that, and the tamping tool is moved automatically based on the detected information.

In FIG. 2, reference numeral 16 denotes a control device of the presetting device 3. FIG. 4 shows the operation panel 17 of the presetting device 3. Furthermore, in FIG. 3, the code | symbol 23 is a distance meter. This distance meter 23 is for recording the distance data from the sleeper which starts measurement to the ID tag 10.
[0022]
On the other hand, the automatic position setting device 5 of the multi-tie 1 is disposed in the tamping tool operation room in the vehicle, and the operation panel 18 shown in FIG. 6 is operated by an operator near the tamping tool operation panel (not shown). It is attached to the place where it is easy to do. The automatic position setting device 5 receives the information written in the ID tag 10 by the receiving unit 15 of the data transmission device 6 through the receiving antenna 8, and each of the twelve tamping tools 4a to 4f according to the received information. And so on. In order to set the position of each tamping tool 4a to 4f, etc., it is necessary to know the position and movement amount of each of these tools. A wire type potentiometer (not shown) is attached to each tool. ing. Further, a measurement wheel 19 provided with a pulse transmitter for distance measurement is attached outside the vehicle in the forward direction of the tie 1 so that it can travel on the track 2.
[0023]
As shown in FIG. 7, data transmission device 6 includes a transmission unit 14 mounted on the pre-setting apparatus 3 is composed of a receiving unit 15 mounted on Marutai 1, embedded ID tag 10 Metropolitan to sleepers 9 The A signal from the transmission unit 14 is written by an electromagnetic modulation wave to the ID tag 10 embedded in the sleeper 9 via the transmission antenna 7, and then information from the ID tag 10 is received by the reception unit 15 via the reception antenna 8. It is received and output to the automatic position setting device 5. The operation principle of the data transmission device 6 is as follows .
[0024]
That is, the transmission unit 14 and the reception unit 15 have basically the same configuration, and include the transmission antenna 7 or the reception antenna 8 and the transmission / reception decoder 20. On the other hand, the ID tag 10 includes an internal antenna 21 and a special IC chip 22 and receives an electromagnetically modulated wave transmitted only for 30 ms, for example, from the antennas 7 and 8 of the transmission unit 14 or the reception unit 15. The energy for operation and response is given by and stored in the capacitor. When the transmission from the transmission unit 14 and the reception unit 15 is completed, the information written and stored in the special IC chip 21 is automatically transmitted by the electric charge accumulated in the capacitor.
[0025]
The transmission unit 14 transmits an electromagnetic modulation wave having a predetermined frequency in response to a transmission command signal, supplies energy for operation to the ID tag 10, writes predetermined information to the special IC chip 22 of the ID tag 10, and is updated each time. Information is updated and recorded. The receiving unit 15 transmits an electromagnetic modulation wave having a predetermined frequency to the ID tag 10 in response to the transmission command signal, and supplies response energy to the capacitor. When the transmission of the radio wave from the receiving unit 15 is completed, the ID tag 10 transmits the information stored in the special IC chip 22 by the electric charge accumulated in the capacitor. This is received and the content is read.
[0026]
As the ID tag 10, a commercially available transponder such as a plate type or a cylinder large type can be used. In addition, since the ID tag 10 exchanges information using electromagnetically modulated waves, even if the ID tag 10 has a bad weather such as nighttime, rain, snow, etc., which is difficult to confirm visually, or the ID tag 10 is soiled, it does not matter. Therefore, it is possible to reliably exchange information within a range where communication is possible, and it is extremely reliable. Further, the ID tag 10 is a ROM that can store, for example, 1024-bit data, and includes position data of each sleeper 9, twelve tamping tools 4a to 4f corresponding to each of the plurality of sleepers 9, and the like. It is possible to record the position data and distance data in millimeters. The storage capacity may be changed as appropriate according to the amount of data handled.
[0027]
Next, an operation mode of the automatic tamping device configured as described above will be described based on the flowcharts of FIGS. First, the preset vehicle 3 is brought into the start point of the section where the tamping work is performed, assembled, placed on the track 2, and the base 11 is moved to the position of the start sleeper 9 where the tamping work is started to prepare. As shown in FIG. 9, the start position is set by adding start information (line name, up line or down line type, line type) to the ID tag 10A embedded in the sleeper 9 just before the sleeper 9 to start tamping. The distance from the starting point of the kilometer, the tamping start point, etc.) is recorded in advance, and the information may be read. The reading may be performed by transmitting an electromagnetic modulation wave from the antenna 7 to the ID tag 10 </ b> A to supply response energy, transmitting the stored information, receiving it by the antenna 7, and reading it by the transmitter 14. Then, put the electric Minamotosu switch of the operation panel 17 shown in FIG. 4, center the mount 11 to the next center of the measured sleepers 9. This center alignment may be performed by aligning the cross laser of the laser device 13 to the center of the sleeper 9 as shown in FIG.
[0028]
After that, the line condition of the planned position where the twelve tamping tools 4a to 4f of the tie 1 are dropped is confirmed by the corresponding point lasers A1 to 6 and B1 to B6. The confirmation is performed by irradiating the light of the point laser onto the orbit and checking whether there is a line incidental facility such as a branching device that interferes with the tamping tools 4a to 4f at the irradiation point. If the found avoid interference tamping for tamping tool if set its position by moving the point laser A1~A6 and B1~B6 to X-Y axis direction, it is impossible to avoid interference applicable not Make it possible. At the same time, the distance data from the position of the sleepers 9 where the tamping is started is measured by the distance meter 23 of the presetting device 3. Thus, the position data and distance data obtained for the tamping scheduled positions of the tamping tools 4a to 4f, etc. are read by selecting the switch of the operation panel 17 for each tool and pressing the read switch.
[0029]
In this way, the pre-setting device 3 measures and reads the position data and distance data of the tamping tools 4a to 4f etc. for a predetermined number of sleepers 9, and then presses the transfer switch on the operation panel 17 to read these data. Collectively, the data is transmitted from the transmission unit 14 of the data transmission device 6 to the ID tag 10B embedded in the sleepers 9 by electromagnetic modulation waves and recorded on the special IC chip 22. Thereafter, the above-described operation is repeated, and dropping information such as the tamping tools 4a to 4f for all the sleepers 9 in the tamping work section is recorded in the ID tag 10C. FIG. 9 is a plan view when information obtained in this way is plotted on a drawing representing a trajectory. The position of X is the position where the tamping tool is dropped.
[0030]
Next, when the position data and distance data of the tamping tools 4a to 4f corresponding to the respective sleepers 9 are recorded in the ID tag 10 in this way, the multitude 1 then follows as shown in FIG. Perform tamping work automatically. This automatic tamping operation is performed based on the flowchart shown in FIG. That is, first, in order to position the reception antenna 8 of the tie 1 to the position of the start sleeper 9 in which the ID tag 10A is embedded, the tie 1 is moved and stopped, and the operation panel 18 of the automatic position setting device 5 shown in FIG. Turn on the power switch. The multi-tie 1 transmits an electromagnetic modulation wave from the receiving antenna 8 to the ID tag 10A and supplies response energy. The ID tag 10A transmits the position information of the start sleeper 9 stored by the response energy. The receiving unit 15 receives the information and confirms that it is the start position.
[0031]
After that, I will advance Multai 1 forward. The forward movement of the multi 1 can be known by the distance meter 19 with the advanced distance. When the tie 1 reaches 30 cm before the sleeper 9 in which the ID tag 10B is embedded, each of the information recorded on the ID tag 10B is exchanged by the electromagnetic modulation wave between the receiving unit 15 and the ID tag 10B. Position data and distance data of the tamping tools 4 a to 4 f and the like are read into the receiving unit 15. This information is taken into the automatic position setting device 5, and the actual tamping positions of the tamping tools 4a to 4f and the like are automatically set by computer control according to the information.
[0032]
Further, when the tie 1 moves forward and the center position of the corresponding sleeper 9 such as the centering tooling tools 4a to 4f enters within an error range of ± 10 mm, a buzzer sounds, and the operation panel 18 shown in FIG. The position lamp illuminates, followed by the set completion lamp. The operator stops the tie 1 and causes the tamping tools 4a to 4f to start the tamping operation. The operator need only command this start. Thereby, it is possible to perform an appropriate and reliable tamping work according to the track situation immediately before the start of the tamping work measured by the presetting device 3. Thereafter, an automatic tamping operation may be performed by moving to the next sleeper 9 and repeating the above-described operation.
[0035]
By the way, this invention is not limited to embodiment mentioned above, A suitable change is possible. For example, the presetting device 3 may be fixed to a cart or the like in addition to the assembly type. In addition to the branch line, the line to be subjected to the tamping work by the apparatus of the present invention includes a railroad crossing, a station premises, and a line laid with facilities that interfere with other tamping tools.
[0036]
【The invention's effect】
As described above, in the present invention, immediately before the start of the tamping work, the position data and the distance data detected by checking the line condition at the tamping planned position of each tamping tool are recorded in the ID tag. It is possible to perform tamping work by controlling each tamping tool individually and automatically based on this information, so that accurate tamping work can be performed automatically, which is the most dangerous in tamping work. Therefore, it is possible to omit a ground worker who is large and unfavorable in terms of work environment. In addition, the operator on the vehicle can reduce the mental and physical burden, and can ensure efficient and safe work.
