DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a track bed replacement system in railway track maintenance work, and more particularly to a system for replacing a ballast laid under a sleeper supporting a rail.

[0002]

2. Description of the Related Art As a method of replacing a ballast laid under a sleeper supporting a rail, a work method using two tracks has been conventionally proposed. In this method, the first work train for scraping the old ballast and the third work train loaded with the new ballast are on standby on the same track, but the second work train for loading the scraped old ballast is used. 'S work train is waiting on another adjacent track. In this method, the old work ballast is scraped off by the first work train and is carried out from the carry-out conveyor to the second work train waiting on the adjacent track via the second carry-out conveyor. On the other hand, the third work train moves to the excavated portion after the scraping work of the old ballast by the first work train is completed, and throws the new ballast into the excavated portion. However, according to such a conventional work method, the old ballast scraped off by the first work train is loaded on the second work train waiting on the adjacent track, so that the work is performed with the two tracks closed. It may be necessary and may hinder the operation of railway vehicles. In addition, since the first to third work trains must be operated individually, the replacement work of the old ballast itself becomes large-scale, requires a large number of personnel, and poses a problem in terms of cost. Remains.

[0003] In order to solve such a drawback, there has been proposed a work system that effectively uses one line. A first work train for scraping and loading the old ballast and a second work train loaded with the new ballast are each formed as a single train and wait on the same track for ballast exchange. After scraping the old ballast and loading it with the first work train, the second work train 2 loaded with the new ballast moves to the excavated part on the track where the old ballast scraping work has been completed and replaces the new ballast A way to do that has been proposed.

However, in the conventional working method, two trains, a first working train for scraping and loading a ballast and a second working train for loading a new ballast to be replaced, are independently provided. They must be knitted, in other words, these first and second work trains must be operated individually and independently. For this reason,
Ballast replacement requires a large number of personnel, and is expensive.

Further, the second work train loaded with the new ballast moves to the excavated portion on the track after the ballast scraping work by the first work train is completed. It takes time to change trains,
There is a problem that the work time required for ballast replacement becomes long.

In order to solve such a drawback, the inventor of the present invention has integrated a first work train for scraping and loading a ballast and a second work train for loading a new ballast to be replaced. Has proposed a single ballast exchange train connected to one work vehicle. (Application No .: Japanese Patent Application No. Hei 11)
(No.-259033, unknown)

FIG. 2 schematically shows a work train 5 consisting of two trains used for exchanging ballasts according to the above-mentioned invention. A ballast work vehicle 1 to be loaded, five hopper vehicles 5a to 5e as ballast ballast loading vehicles, and two track driving vehicles 9a and 9b tow the ballast work vehicle 1 and the hopper vehicles 5a to 5e. These are all connected by connectors 11a to 11g. Further, no new ballast 10 is deposited on the frontmost hopper wheel 5e on the side of the driving wheel 9a.

[0008] Ballast work vehicle 1 connected to the rearmost part
Is a ballast scraping device 2 installed at the rear of the vehicle
And a carry-out conveyor 3 as a means for carrying out the scraped ballast. Since the ballast scraping device 2 has the same configuration as the conventional ballast scraping device, detailed description thereof will be omitted.

The ballast scraped by the ballast scraping device 2 is carried out from the upper part of the body of the ballast work vehicle 1 via the carry-out conveyor 3 to the belt conveyor 7a above the first hopper car 5a. 5b are sequentially transferred via the upper belt conveyor 7b to the hopper wheel 5e from the forefront.

On the other hand, at the same time as the old ballast is scraped, the new ballast 10 loaded on the rearmost hopper 5a passes through the second and third belt conveyors 8a, 6a provided below the hopper 5a. The new ballast 10 is transferred to the input conveyor 4 of the ballast work vehicle 1 and is excavated through the input conveyor 4 to the excavated portion where the old ballast has been scraped off. The second-stage hopper truck 5 from the rear end in parallel with the loading
b is transferred to the rearmost hopper wheel 5a via the second belt conveyor 8b and the third belt conveyor 6b, and the new ballast 10 is sequentially transferred to the second belt conveyor 8c. The hopper wheel 5d is sequentially transferred to the rearmost hopper wheel 5a via the belt conveyor 6c, and the hopper wheel 5d → the hopper wheel 5c → the hopper wheel 5b. During this time, the ballast after being scraped is deposited on the last hopper wheel 5e, but when the last hopper wheel 5e is full, the new ballast of the next hopper wheel 5d is replaced with the previous hopper wheel 5e. The entire hopper car 5d is empty after being transferred to the car 5c.

The full ballast deposited on the forefront hopper wheel 5e is sent to the next hopper wheel 5d via the second belt conveyor 8e and the third belt conveyor 6e. In the following, similarly, the operation is completed when the old ballast is transferred to the intermediate hopper wheels 5d to 5b sequentially from the last hopper wheel 5e to the hopper wheel 5b and becomes full. On the other hand, similarly, the new ballast 10 is similarly transferred to the intermediate hopper cars 5c to 5b sequentially from the next hopper car 5d, transferred to the hopper car 5a, and put into the excavation portion via the loading conveyor 58 of the ballast work vehicle 1. The work is completed at the stage where it is completed. Therefore, as ballast replacement progresses, the hopper 5
As new ballasts are sent out from the loading platforms a to 5d, the scraped ballasts 10 are loaded onto the loading platforms of the hopper trucks 5e to 5b, and are loaded in one train train 51. Since the replacement of the new ballast 10 with the scraped ballast is performed, the scraped ballasts are evenly placed on the hopper cars 5b to 5e without overflowing of the hopper cars 5a to 5e. Be loaded.

[0012]

In such a roadbed replacement system, the ballast scraping device for the ballast work vehicle 1 is pulled by the track drive vehicles 9a and 9b while pulling the ballast work vehicle 1 and the hopper vehicles 5a to 5e at a constant low speed. In this method, the old ballast and the new ballast 10 are exchanged by scraping the ballast in step 2. The track driving vehicle 9, the ballast work vehicle 1, and the hopper vehicles 5a to 5e have a connected knitting structure connected by connecting machines 11a to 11g, respectively. However, the speed at which the ballast work vehicle 1 scrapes up at the scraping device 2 varies depending on the state of the roadbed. Therefore, if the track driving vehicle 9 constantly pulls at a constant low speed, a large load is generated on the scraping device 2 and the excavating capacity is reduced. In the worst case, the scraper 2 may be damaged. In order to avoid this, the operator of the track driving vehicle 9 checks the operation status of the ballast work vehicle 1 using a monitoring monitor such as a camera separately, wireless communication with a worker near the ballast work vehicle, or the like. However, since the speed of the track driving vehicle 9 must be controlled, it is very difficult and requires skill.

An object of the present invention is to provide a ballast replacement vehicle system which can be operated smoothly and without requiring skill even if a load variation of a scraping device on a ballast work vehicle occurs in view of the above problem. Is to do.

And a sensor for detecting a relative speed between the two trains, wherein the running speed of at least one train is controlled based on a signal from the sensor. The sensor is a speed sensor or a distance sensor that measures the inter-vehicle distance of both trains in time series. For example, as described in claim 2, a distance sensor for detecting an inter-vehicle distance between the first train and the second train is provided, and at least one train is formed based on a signal from the distance sensor. You may comprise so that the driving speed of a vehicle can be controlled.

This invention separates the ballast worker whose load fluctuates, as in the prior application, and controls the speed or distance so that the ballast loading vehicle is within a predetermined inter-vehicle distance range. The speed of the track driven vehicle can be automatically controlled in accordance with the excavation speed of the scraping device of the car, so that no unnecessary load is applied to the scraping device and the operator of the track driven vehicle is skilled in speed control. It is no longer necessary to have Of course, as set forth in claim 3, the travel speed of at least one train can be controlled by combining the distance displacement and the relative speed displacement between the first train and the second train. This allows more precise control.

According to a fourth aspect of the present invention, there is provided a ballast collection conveyor and a replacement ballast provided respectively on the second train on the ballast work vehicle side and the first train on the ballast loading vehicle side separated from the second train. At each of the transfer conveyors, the carry-in end and the carry-out end are superimposed in a non-contact state with each other, and the inter-vehicle distance is maintained between the two trains so that the superimposed portions are not completely separated from each other. It is characterized in that the running speed of the train is controllable. According to this invention, even if the first train and the second train are separated from each other, the ballast can be collected and put in smoothly without falling on the track.

According to a fifth aspect of the present invention, the collection conveyor group for collecting the ballast working vehicle is formed in the backward movement direction toward a ballast loading vehicle located farthest from the work vehicle, and is formed on the other hand.

A second train is formed sequentially in the forward movement direction,
It is characterized in that the carry-in end and the carry-out end of the ballast collection conveyor and the ballast transfer conveyor facing the formation car separated from this are overlapped in a non-contact state.

Even if the second train on the work vehicle side and the first train on the ballast loading vehicle side are separated from each other, the carry-in end and the carry-out end of the ballast collection conveyor and the ballast transfer conveyor between them are not separated from each other. Because it is superposed in the state of contact, the ballast can be continuously performed from scraping of the ballast to loading and loading of new ballast without the ballast accidentally falling on the track. This also contributes to shortening the working time and does not hinder the operation of railway vehicles.

The ballast work vehicle has self-propelled means together with unloading means for unloading the scraped ballast to the ballast loading vehicle and input means for inputting a new ballast from the ballast loading vehicle side to the ballast excavation part. It is characterized by things.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. However, unless otherwise specified, dimensions, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the invention, but are merely illustrative examples. FIG. 1 is a schematic diagram showing a roadbed change-forming vehicle according to an embodiment of the present invention. Since the configuration of each vehicle of the present invention is basically the same as the prior application technology, the description will be focused on the differences from the prior application technology. This train 50 is a self-propelled ballast work vehicle 12 for scraping and injecting ballast, an intermediate bogie 2
2 and 5 hopper cars 19a to 5 as ballast loading cars
Two track driven vehicles 20a, 20b towing only 19e
And these are all connected by connectors 27a to 27f. Further, no new ballast 10 is deposited on the frontmost hopper wheel 19e on the side of the driving wheel 20a.

Ballast work vehicle 1 connected to the rear end
Is a ballast scraping device 1 installed at the rear of the vehicle body
3 and an unloading conveyor 14 as an unloading means for scraping the ballast. The ballast scraping device 13
Since it has the same configuration as the conventional ballast scraping device, its detailed description is omitted. The ballast work vehicle 12 and the intermediate carriage 22 are connected by a connection device 23, and are driven by the ballast work vehicle. The track driving vehicles 20a and 20b and the hopper vehicles 19a to 19e are connected by connecting devices 27a to 27f, respectively. Scraping device 1 for ballast work vehicle 12
3 and is sent to the upper belt conveyor 25 of the intermediate carriage 22 through the unloading conveyor 14 and further successively by the upper belt conveyor 17a of the succeeding hopper car 19a.
are sequentially transferred to the hopper wheel 19e from the foremost part through b.

On the other hand, at the same time as the old ballast is scraped, the new ballast 10 loaded on the rearmost hopper 5a passes through the second and third belt conveyors 18a and 16a provided below the hopper 19a. The ballast is transferred to the intermediate carriage 22, transferred to the loading conveyor 15 of the ballast working vehicle 1 via the lower belt conveyor 24 in the carriage 22, and a new ballast is formed on the excavated portion where the old ballast is scraped off via the loading conveyor 15. 10 is input. In parallel with the loading, the new ballast 10 loaded on the second-stage hopper wheel 19b from the rearmost position is moved to the rearmost hopper wheel 19a via the second belt conveyor 18b and the third belt conveyor 16b.
, And then sequentially transferred via the second belt conveyor 18c and the third belt conveyor 16c to the hopper wheel 19a, the hopper wheel 19c, and the hopper wheel 19b to the last hopper wheel 19a. During this time, the ballast after the scraping is deposited on the last hopper wheel 19e, but when the last hopper wheel 19e becomes full, the new ballast of the next hopper wheel 19d is replaced with the previous hopper wheel 19e. Car 19
c, and the next hopper 19d is empty.

The full ballast accumulated on the forefront hopper wheel 19e is sent to the next hopper wheel 19d via the second belt conveyor 18e and the third belt conveyor 16e. In the same manner, the operation is completed when the old ballast is transferred to the last hopper wheel 19a and becomes full by being sequentially transferred from the last hopper wheel 19e to the hopper wheels 19d to 19a.

This configuration is the same as that of the prior application except that the vehicle has an intermediate bogie. However, since the rearmost hopper wheel 19a and the intermediate bogie 22 are not connected by a coupler, some of the two The discharge end of the upper belt conveyor of the intermediate carriage 22 and the carry-in end of the belt conveyor 17a of the rearmost hopper car 5a are also superimposed even by the separation, so that the ballast being carried out is prevented from dropping onto the track by mistake. Also, the unloading end of the lower belt conveyor 17a of the rearmost hopper truck 5a and the loading end of the lower belt conveyor 24 of the intermediate bogie 22 are overlapped,
Make settings so that ballasts during loading do not accidentally fall on the track.

The present invention relates to a rear hopper wheel 19a.
Is mounted with a distance sensor 26 for measuring a distance from the intermediate carriage 22. The distance between the hopper car 19a and the intermediate bogie 22 measured by the distance sensor 26 is fed back to the track drive vehicle 20, and the vehicle speed of the track drive vehicle 20 is controlled so that the inter-vehicle distance becomes constant.

Next, a method of controlling the vehicle speed of the train 50 with the change of roadbed will be described with reference to a control flowchart of FIG. In the control flow, first, a speed difference region between the track driving vehicle 20 and the ballast work vehicle 12 and an inter-vehicle region between the intermediate bogie 22 and the last hopper vehicle 19a are set. (S1) The relative speed between the track driving vehicle 20 and the ballast work vehicle 12 is calculated based on the distance from the intermediate bogie 22 sent from the distance sensor 26 of the last hopper vehicle 19a. The relative speed may be obtained by differentiating the distance signal obtained by the distance sensor in time series, and the vehicle speed V detected based on the speedometer provided on the track driving vehicle 20 and the speedometer of the ballast work vehicle 12 may be obtained. Based on the difference from the excavation speed V ′ detected based on the relative speed (V−
V ′) may be obtained. (S2)

Next, the output signal is determined under the following conditions. When the inter-vehicle distance is smaller than the minimum inter-vehicle area (set in advance) between the intermediate bogie 22 and the last hopper car 19a (too close) (S3), the relative speed is positive (vehicle speed of track-driven vehicle> vehicle speed of ballast work vehicle) ), The speed is maintained as it is in the direction away from the minimum inter-vehicle area. (S4) If the relative speed is 0 or less (vehicle speed of the track-driven vehicle ≦ vehicle speed of the ballast work vehicle), the vehicle is approaching the minimum inter-vehicle region, and the speed increase amount of the track-driven vehicle is calculated to increase the speed. Move to the inter-vehicle area. (S5)

When the inter-vehicle distance is in the proper inter-vehicle region between the maximum inter-vehicle region and the minimum inter-vehicle region, the relative speed (V-V ') is smaller than the minimum speed difference region. Calculate the amount of speed increase to increase the speed, and maintain an appropriate inter-vehicle area. (S5) If the relative speed (V-V ') is larger than the maximum speed difference region even in the appropriate inter-vehicle region, the deceleration amount of the track-driven vehicle is calculated and decelerated to maintain the appropriate inter-vehicle region. (S7) If the relative speed (V-V ') is within the speed difference region in the proper inter-vehicle region, the speed is maintained. (S6)

If the inter-vehicle distance is larger than the maximum inter-vehicle area (too far away) (S9) If the relative speed is 0 or more (vehicle speed of the track driving vehicle ≧ vehicle speed of the ballast work vehicle), the vehicle is in a direction away from the maximum inter-vehicle area, The deceleration is performed by calculating the deceleration amount of the driving vehicle, and the process shifts to the appropriate headway range. (S7) If the relative speed is negative (the vehicle speed of the track-driven vehicle <the vehicle speed of the ballast work vehicle), the vehicle is approaching the maximum inter-vehicle region and is transitioning to the appropriate inter-vehicle region, so that the speed is maintained as it is. (S8) The distance detection by the distance sensor (S10) and the speed control of the track-driven vehicle are performed for each cycle time, and the track-driven vehicle is automatically controlled.

[0031]

As described above, according to the present invention, the speed of the track driving vehicle is automatically controlled in accordance with the excavation (scraping) speed of the scraping device of the ballast work vehicle. It does not apply an unnecessarily large load, and the operator of the track-driven vehicle does not need to be skilled in speed control.
