Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-held, simple and lightweight track inspection vehicle and a dividing method for facilitating the handling of the track inspection vehicle.

[0002]

2. Description of the Related Art In a track forming a railroad track, left and right rails are deviated from a reference position due to train operation or the like. This deviation is called an orbit and five items are specified.
Although each item is well-known to the people concerned, if you enumerate it for the time being, deviation: horizontal deviation from the reference position of each rail, elevation deviation: vertical deviation from the reference position of each rail, gauge deviation: both rails Deviation from the reference gauge, level deviation: height difference of both rails, flatness deviation: deviation of the plane made by both rails with respect to the plane during a certain distance. It should be noted that, in general, there are 10 cases of passing and high and low.
The standard method is to set a measurement string of m and measure the deviation (straight arrow) of the rail with respect to its midpoint. By the way, in the main line area where a large number of commercial trains operate, a large track inspection vehicle is composed of vehicles of almost the same standard as the commercial vehicles, and it is towed by electric or diesel locomotives at high speed. Each track deviation is inspected while running.
However, large inspection vehicles are not suitable for off-road areas where the number of trains is low and for side lines inside the station, so
A medium- or small-sized inspection device (inspection vehicle) has been studied or developed, and a series of patent applications have been filed.

FIG. 15 shows an example of a Japanese Patent Publication No. 4-1803, a track inspection device, which is published as a patent application, as an example of a small inspection vehicle. (However, the names and symbol numbers of each component are appropriately changed and shown, and the same applies to each patent application hereinafter). Both rails are RL1 and RL2, and they are composed of a central carriage M having wheels W1 and W2 contacting them, and two joining carriages F detachably joined to the front and rear thereof and having wheels W3. , Street detectors T1, T
2, T3, height detector E, gauge detector G, level detector H, and distance pulse generator K directly connected to the wheel W2.
And an arithmetic processing unit C mounted at the illustrated position. The detection signal of each detector is processed by the arithmetic processing unit C, and the deviation amounts of the above-mentioned 5 items are all obtained and printed on the recording paper. The length of this inspection device is about 5 m, and the deviation amount of the street and the height is measured for a 5 m measuring string. Although the total weight and running method are not shown, it is considered to be appropriate to pull by an appropriate towing vehicle because the weight of the vehicle is quite large in view of its size.

[0004] FIG. 16 discloses a simple measuring device as compared with the above-mentioned measuring device, which is disclosed in the patent application "JP-A-63-63."
-272802, simple measuring device for actual track shape "will be described. For one rail RL1, an extendable reference beam F1 having wheels W1, W2, W3 is provided at both ends and in the center,
An auxiliary beam F2 having a wheel W4 for the rail RL2 is fixed at the tip in the direction perpendicular to the central portion thereof so as to be movable on the track. The length of the reference beam F1 is about 5 m when extended. Consists of displacement sensors T1, T2, T3 arranged at the positions of the wheels W1, W2, W3, a distance pulse generator K directly connected to the wheels W2, and an arithmetic processing unit C mounted at appropriate positions. Then, each deviation sensor detects the deviation of the height and height of one rail RL1 with respect to the 5 m measuring string.
The arithmetic processing unit C converts it into a deviation amount of a 10 m string and outputs it. In this simple measuring device, the deviation amount is measured with respect to one rail RL1, and the measurement with respect to the other rail RL2 is performed by reversing the direction of the vehicle body. Further, the inspection for each deviation amount of gauge, level, and flatness is not disclosed, and it is for the purpose of simplicity.

Generally, in a simple measuring device, it may not be possible to smoothly pass through a branch point of a rail or the like because the diameter of the wheel is small. Figure 17 shows the rail bifurcation
When the movable tip rails RLT1 and RLT2 are at the positions indicated by the dotted lines,
The left rails RL1 and RL2 are shown on the right side rails RL1 and R
It is connected to L2, and when RLT1 and RLT2 are converted to the positions indicated by the solid lines, they are connected to rails RL1 'and RL2'. There is a fixed track (crossing, CR) at the intersection of both rails. In CR, the rail is open with a gap of length LK, and if the wheel diameter is small, it fits into this broken line and passes. It cannot be done. On the other hand, there is a patent application publication “Japanese Patent Application Laid-Open No. 2-171402, a branch passage mechanism in a portable track inspection device”, and the gist thereof is that in the simple measuring device of FIG. An auxiliary beam having guide rollers is provided to prevent the wheel W4 from being fitted into the broken line portion by each guide roller.

Next, FIG. 18 shows another example of a small-sized inspection device, which is disclosed in Japanese Patent Application Laid-Open No. 61-60906.
No. The inspection device passes two beams F1 and F2 at right angles to both rails RL1 and RL2, and couples them with two beams F3 and F4. Each beam F1,
Wheels W having flanges for preventing wheel loss are attached to both ends of F2 so as to be movable. To the support beams F5 and F6 fixed to the beams F3 and F4, a moving plate D that moves in the direction of the arrow B is attached, and a gauge detector S1 and a gauge detector S1 are attached at the positions shown in the figure.
A level detector S2 and a height detector S3 for the rail RL2 are provided, and a distance pulse generator S4 is attached to the wheel W at the position shown. Further, a guide shoe GS having a plurality of guide rollers is provided at the end of the moving plate D, which comes into contact with the rail RL1 to move the moving plate D left and right according to its deviation, and at the same time, the guide rollers GS1 It is prevented from fitting into the broken line portion.

Further, in this inspection device, the rail R
To get a clear measurement string for L1, rail RL1
A reference line L formed by a wire or a laser beam is set between the front and rear positions of the device by a suitable method. On the other hand, the moving plate D is provided with a detector T and a height detector E for the rail RL1, which detect the position of the reference line L to detect the amount of deviation from the height. The detection signal of each detector is processed by the arithmetic processing unit, and the deviation amount of 5 items is output to the recording paper of the printer. In this inspection device, most of the detectors are mechanically configured, and the guide shoe GS also has a plurality of guide rollers, so there is a limit to weight reduction of these. In addition, the setting of the reference line L requires stopping the inspection device (vehicle body), which cannot be continuously measured.

[0008]

Recently, in order to save labor in the inspection work of the outlying line areas and the lateral lines, it is possible to travel at a low speed by hand and to continuously inspect all five items. Measuring cars are required. In this case, when a train or vehicle approaches during inspection, it is absolutely necessary to immediately remove it from the track, and the inspection vehicle should be made as light as possible to facilitate hand-held driving and transportation. It is a necessary condition. On the other hand, like the above-mentioned inspection devices,
Needless to say, the one that requires a towing vehicle is too heavy, the inspection items are limited to some items, the continuous inspection is impossible, and the one side rail is inspected. Inappropriate to The present invention has been made in response to the above-mentioned demands, is small and lightweight, travels at a low speed by pushing manually, passes through a branch point without trouble, and continuously measures all five items of track deviation, and To provide a simple track inspection vehicle that converts the deviation amount of the street and high and low to a 10 m string and output the data of each deviation amount, and a division method for facilitating the handling of this track inspection vehicle. To aim.

[0009]

The present invention is a simplified track inspection vehicle that achieves the above-mentioned needs. A reference beam and a rotating beam, which are arranged in parallel directly on the left and right rails, and have traveling wheel portions that form a measuring string of 1.25 m at both ends, and one end is fixed to the central portion of the reference beam. , The other end of the rotating beam pivotally supports the expandable and contractable connecting beam to form the inspection vehicle body. Each of the coupling beams has a spring that presses the pivoting beam that is axially supported outward, and a stopper that limits the pivoting of the pivoting beam within a horizontal plane to a minute angle.
Further, a high / low deviation detecting section and a passing deviation detecting section arranged at the central portions of the reference beam and the rotating beam, a gauge sensor and a level sensor respectively arranged on the coupling beam, and a height measurement on the reference beam side. It consists of a distance pulse generator directly connected to the wheels, and a data processing unit and a power supply unit mounted on the inspection vehicle body. This is to continuously measure each orbital deviation.

In the above, each traveling wheel portion is composed of a traveling wheel that contacts the tread surface of each rail, a guide wheel that contacts the inner surface of the head of each rail, and a guide shoe that guides the guide wheel. The position detection unit is composed of a height measurement wheel that is pressed by a spring and moves up and down in contact with the corresponding tread surface of each rail, and a height sensor that detects the up and down movement. , A measuring wheel that moves to the left and right while contacting the inner surface of each corresponding rail, and a sensor that detects the left and right movements, and the data processing unit has each height sensor, each sensor, level sensor, and gauge sensor. Each of the detection signals is processed to calculate the amount of track deviation of the height, passing, gauge, level, and flatness of both rails, and the calculated height and passing amount of 10 are calculated. Into a chord length, with respect to calculated or transformed the deviation amount of data, distance pulses by adding the travel distance data that is being E by counting and outputs.

In the above description, each part constituting the inspection body is made of aluminum or its alloy as a main component and is lightweight, and each height sensor, each street sensor and gauge sensor are
With laser type distance sensor and aluminum reflector,
The level sensor is composed of an electronically controlled servo accelerometer, and the distance pulse generator is composed of a laser transmitter / receiver and a hole disk directly connected to the height measuring wheel. The data processing unit records all the data of the deviation and the mini-printer that immediately prints the deviation when the calculated or converted deviation exceeds the reference value. I that can be processed and output to a chart printer
And a C card, and the power supply unit is composed of a lithium storage battery.

The simple track inspection vehicle of the present invention having the above-mentioned structure can be removed from the track immediately when a train or the like approaches as described above, and in order to facilitate manual running or transportation, The aluminum has been made as lightweight as possible. However, the total total weight reaches about 50 kg, and handling is not always easy. Looking at each part, the body is about 40k including various wheels and sensors.
g, the data processing unit 7 including the power source is about 10 kg. In order to facilitate this handling, it is effective to divide the inspection vehicle 10 appropriately. Further, in order to facilitate the transportation of the divided parts, it is desirable to store them in a case, for which purpose it is necessary to make each part as compact as possible.

Therefore, in order to facilitate the handling of the simplified track inspection vehicle, the invention is directed to a method of dividing the simplified track inspection vehicle in which the connecting beam of the simple track inspection vehicle is located near the reference beam. Divide by the dividing mechanism with. The part of the divided connecting beam on the side of the rotating beam is rotated around its pivot point and temporarily fixed to the rotating beam. In addition, a bending mechanism is provided at the base of the hand-pushing handle, and the hand-pushing handle is bent around this to temporarily fix it to the reference beam, and the data processing unit and power supply unit are detachably fixed to the reference beam, and then split. It is to be removed at the time of.

The portion of the connecting beam divided by the dividing mechanism on the side of the reference beam is shorter than the portion on the side of the rotating beam, so that it is left as it is, but the longer portion on the side of the rotating beam hinders compactness. Therefore, it is rotated around the pivot point and temporarily fixed to the rotating beam. Further, since the hand-pushing handle is also an obstacle, it is bent around a bending mechanism provided at its base and temporarily fixed to the reference beam. Further, the data processing unit and the power supply unit are detachably fixed to the reference beam and are not removed when dividing. Due to the above, the vehicle body is approximately 20 kg
It is divided into two parts, and the data processing part and power supply part of about 10 kg are separated to facilitate the handling of each. Furthermore, by temporarily fixing the connecting beam and the hand-pushing handle, each divided part is made compact, and is housed in a case or the like for convenient transportation.

The above dividing mechanism divides a portion of the cylinder portion of the connecting beam near the reference beam, and divides one end portion into one of the divided end portions.
Provide a tightening ring that can be tightened with a buckle. In addition, a fitting portion having a diameter that fits into the tightening ring is formed at the other divided end portion, the fitting portion is inserted into the tightening ring, and the buckle tightens to assemble the vehicle body. When splitting the car body, loosen the buckle and pull out the fitting part to split it. Two rotation stopper plates each having a pin hole corresponding to each other and fixed to the base portion of the coupling beam pivotally supported on the above-mentioned pivot point and the side surface of the rotating beam, and a slightly thin fixing pin to be inserted into the pin hole. When the vehicle body is assembled, the fixing pin is inserted into the pin hole to limit the rotation of the coupling beam to a minute angle. When the vehicle body is divided, the fixing pin is pulled out, and the connecting beam is pivotally fixed.

[0016]

In the above simple track inspection vehicle, the traveling wheel portions provided at both ends of the reference beam and the rotating beam at intervals of 1.25 m form a measuring string of 1.25 m. Here, the significance of the 1.25 m measuring string, which is one important point of the present invention, will be described. In order to drive by hand, it is necessary to reduce the total weight of the vehicle body and its mounted items as much as possible.
For this reason, the length of the vehicle body is shortened and the mounted object is lightened.
In this case, shortening the vehicle body also shortens the measurement string, so
As shown in the above-mentioned example, it may be converted into a 10 m measurement string by arithmetic processing. However, since the conversion is limited to even multiples (odd multiples are also possible in principle), it is sufficient to use 2.5 m for 4 times, 1.25 m for 8 times, and 0.625 m for 16 times. However, as the number of multiples increases, the error also doubles, so it cannot be set to an unreasonably large multiple. on the other hand,
In the case of narrow gauge, the gauge is 1,067 mm, and if the length of the vehicle body is shorter than this, the vehicle body tends to rotate left and right and is not stable, and the front and rear guide wheels are located at the broken line at the branch point. At the same time, they cannot fit in smoothly. Therefore, in order for the car body to travel stably, its length should be about the same as the gauge gauge,
In order to pass through the broken line portion without any trouble, it is a necessary condition that the distance between the two guide wheels is at least longer than that of the broken line portion.

From the above viewpoints, the present invention provides
The measured chord length is 1.25 m. Each part of the inspection vehicle body is made mainly of aluminum or its alloy and is lightweight, and each running wheel and guide wheel of four running wheel parts are
The tread surface and the inner surface of the left and right rails are in contact with each other, and the vehicle can be stably driven at a speed of 5 to 10 km / hour by manual pushing. Next, the rotating beam, which is axially supported by the other end of the expandable joint beam, is pressed by a spring and is elastically held with respect to the reference beam. Limited to moving angle. Due to the limiting angle and the guide shoe, the guide wheel can smoothly pass without being fitted into the broken line portion of the branch point of the rail. However,
The restriction angle of the stopper and the mounting angle of the guide shoe are related to the diameter of the guide wheel and the length of the broken line portion, and the length of the broken line portion differs depending on the number of the branch device. Each angle is set.

As described above, the method in which the guide wheel passes through the broken line portion without any trouble by only limiting the turning angle of the turning beam has a simpler structure than the above-described guide shoe having a plurality of guide rollers. Is also advantageous in terms of weight.
Next, in each of the height deviation detectors arranged in the central portions of the reference beam and the rotating beam, the height measurement wheel is pressed by the spring and comes in contact with the corresponding tread surface of each rail to move up and down. . The contact point is the midpoint of the 1.25 m measurement string, and the amount of height deviation at this point is detected by each height sensor. In each of the deviation measuring units as well, the passing measurement wheel similarly contacts the inner surface of each rail and moves left and right, and the deviation amount of the passage of the midpoint of the measurement string is detected by each sensor. Further, a gauge sensor and a level sensor, which are respectively arranged on the connecting beams, detect the deviation of the gauge and the level of both rails.

The detection signals of the height sensor, the street sensor, the gauge sensor, and the level sensor are processed by the data processing unit, and the height of the rails, the street, the gauge,
The deviation amount of each of the level and the flatness is calculated, and the height difference and the deviation amount are converted into a 10 m chord length. The distance pulse of the distance pulse generator is counted with respect to each of these deviation amounts of data, and the obtained travel distance data is added and output. In the above, each sensor is constituted by a laser type distance sensor and an aluminum reflector, or an electronically controlled servo accelerometer, and the distance pulse generator is constituted by a laser transmitter / receiver and a hole disc, respectively. Since it is lighter than the mechanical type and the lithium battery of the power source is also lighter, it contributes to the weight reduction of the inspection vehicle. The data of each deviation measured by the above is not necessary immediately during the inspection running, so the data processing unit immediately prints only the deviation of data exceeding the reference value to the mini printer. On the other hand, all the deviation amount data are recorded in the IC card, and after the track inspection is completed, they are processed on the ground and output to the chart printer. The mini-printer and IC card are small and lightweight, which also contributes to weight reduction.

Further, in the dividing method of the present invention, the portion of the connecting beam divided by the dividing mechanism on the reference beam side is left as it is because it is shorter than the portion on the rotating beam side, but the longer rotating beam is used. Since the side portion interferes with the compactness, the side portion is pivoted about its pivot point and temporarily fixed to the pivot beam.
Further, since the hand-pushing handle is also an obstacle, it is bent around a bending mechanism provided at its base and temporarily fixed to the reference beam. Further, the data processing unit and the power supply unit are detachably fixed to the reference beam and are not removed when dividing. As described above, the vehicle body is divided into two parts of about 20 kg, and the data processing part and the power supply part of about 10 kg are separated, which facilitates the handling of each part. Furthermore, by temporarily fixing the connecting beam and the hand-pushing handle, each divided part is made compact, and is housed in a case or the like for convenient transportation.

In the above dividing mechanism, the cylinder portion of the coupling beam is divided at a portion close to the reference beam. When assembling the vehicle body, insert the fitting part formed at the other end into the tightening ring provided at one of the divided ends, tighten the tightening ring with the buckle, and connect the two together. There is. When the vehicle body is divided, the vehicle body can be easily divided by loosening the buckle and pulling out the fitting portion. In the above stopper mechanism, when assembling the vehicle body, a slightly thin fixed pin is inserted into the pin hole of each rotation stop plate, and the rotation of the connecting beam is limited to a minute angle, so that the inspection vehicle runs. At this time, the traveling wheels can pass smoothly without dropping into the broken line portion of the rail branch point. When the vehicle body is divided, the fixing pin is pulled out and the connecting beam is rotated to be temporarily fixed.

This is detected by the height sensor SZ1 or SZ2, and the detection signal is the height calculation circuit 712.
Is calculated, and the amount of deviation of the 1.25 measured strings is calculated for each. Also, both rails RL1, RL
If there is a difference in height between the two, this is detected by the level sensor SH, and the detection signal is processed by the level calculation circuit 714 to obtain the level deviation amount.

Since the deviation amounts obtained as described above are analog amounts, they are digitized by the A / D conversion section 72 and temporarily stored in the MEM 73. Of the stored misalignment amounts, the amounts for the street and the height are sequentially read out and transferred to the 10m string conversion unit 741 and converted into 10m string data. The principle of string length conversion is known, but for the time being,
This will be described with reference to 0. In FIG. 10, it is assumed that the rail RL now forms the illustrated curve, and that the points A, B, to E, F ... Have an interval of 1/2 of the measurement string LG. Measurement string LG
The deviation amount xc of the point C with respect to the midpoint C ′ of the line segment AB
Is measured, and then the measurement string LG is moved to measure the deviation amount xb of the point B with respect to the midpoint B ′ of the line segment CD. Similarly, the deviation amount xd of the point D with respect to the midpoint D ′ of the points B and E is measured. The line segment AE has a double string length 2LG, and its midpoint B "
The deviation amount XB of the point B with respect to is easily obtained by the graphical method, and is calculated by the following equation: XB = xc + 2xb + xd. This method is expanded to 4 times the string length 4L
The deviation amount with respect to the midpoint of G is calculated, and the chord length is 8LG
The deviation amount with respect to can be obtained. In this case, the rail curve must have the same curvature in the doubled chord length range, and the larger the chord length compared to the radius of curvature, the larger the error occurs. Also has the property of doubling. On the other hand, the measured chord length of 1.25 m is much larger than the radius of curvature of the rail, so that an error of 8 times is acceptable.

Referring again to FIG. 6, the level deviation amount stored in the MEM 73 is sequentially transferred to the plane conversion unit 742 to calculate the plane deviation amount. This flatness deviation amount, the deviation amount of the high and low as converted to the above 10 m string, and the deviation amount of the above gauge and level are added with the traveling distance data from the distance counter 716, and are written by the writing circuit 743. Sequentially recorded on the IC card 744. At the same time, each deviation amount is input to the determination unit 745 and compared with a preset reference value. If there is an deviation amount that exceeds the reference value, the data is stored together with the travel distance data in the mini printer 746. Printed on. In the above, when the inspection vehicle 10 approaches the branch point of the rail, the operation of the operation panel 74 stops the output of the inspection data for that portion.
