Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a leveling inspection device for a track straightening machine.

In general, when aligning a track, the vertical adjustment of the top surface of the right or left rail in the longitudinal direction, that is, the height deviation, is corrected, and the height deviation of the left and right rails, that is, the level deviation is corrected. Level adjustment is performed to adjust the level to a predetermined value, and these are collectively referred to as leveling adjustment and are performed by a leveling device of a track straightening machine.

A track straightening machine automatically performs leveling adjustment using a leveling device while running on the rail.It is a leveling measuring device (hereinafter simply referred to as a leveling inspection device) that normally detects height deviations and level deviations of the left and right rails of the track. A rail lifting device (also called a lifting device) that lifts the rail to the leveling adjustment position according to commands from the measuring device, and a rail lifting device (also called a lifting device) that holds the rail at the position lifted by the rail lifting device. It is equipped with a tamping device that compacts the pallast trackbed on the underside of the sleepers using vibrations, etc. Various inspection devices for this type of track straightening machine have been proposed in the past, and a typical one is one in which reference parts are provided at the front and rear of the track straightening machine, and a reference line is formed between these reference parts. However, there is a known measuring device that measures height deviations and level deviations of a rail using a detection part that is provided between a front reference part and a rear reference part and has a reference line sensing means, and a level. .

As an example of this type of measuring device, the height deviation of the rail is measured by the displacement of a reference line sensing means with respect to the reference line, and the level deviation of the rail is measured by a spirit level installed near the tamping device. J had a problem with the response speed of the spirit level when adjusting the level.If the response speed was made faster, it would become unstable due to the vibration of the tamping device, and if the response time was made slower, it would take more time to lift the left and right rails. However, the disadvantage is that the detection level includes an error. The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional leveling inspection device for a track straightening machine.

Hereinafter, the invention will be described in detail with reference to the drawings.

FIG. 1 shows a leveling inspection device 1 for a track straightening machine of the present invention.
This shows a configuration diagram of the front reference part 2 provided at the front of the track straightener, the rear reference part 3 provided at the rear of the track straightener, and the front reference part 2 and the rear reference part. 3, and a reference line 5 formed between the front reference part 2 and the rear reference part 3 (the figure shows the right measurement rail as the reference measurement). In reality, the left measurement rail is sometimes used as the reference measurement, so reference lines are formed on both the left and right rails.) The front reference part 2 has struts 2d and 2e that are swingably attached to both ends of a cart 2c supported by measuring wheels 2a and 2b rolling on rails 20a and 20b and that extend upward. A beam 2f is swingably attached to the upper portions of 2d and 2e in parallel to the carriage 2c.

Further, one end of a reference line 5 is attached to the upper end portions of the columns 2d and 2e. The rear reference part 3 includes rails 20a and 20b.
A trolley 3 supported by measuring wheels 3a and 3b rolling on it
It has struts 3d and 3e that are swingably attached to both ends of c and extend upward, and a beam 3f is swingably attached to the upper part of these struts 3d and 3e in parallel to the trolley 3c.
A reference level 6 is installed on the cart 3c. Also beam 3
In f, the level correction amount of the reference level 6 is input, the reference bar 7 extended toward the measuring section 4 is rotated, and the horizontal rod 8 provided at the end of this reference bar 7 is moved along the track. A level correction mechanism 9 is installed which maintains the slope horizontally in straight sections and in relation to the set cant in curved sections. The inspection unit 4 is the rail 2
0a, 20b, which is supported by measuring wheels 4a, 4b that are supported by measuring wheels 4a, 4b.
A beam 4f is swingably attached to the upper part of the carriage 4c parallel to the carriage 4c.

Between this beam 4f and the horizontal pole 8, there is a leveling displacement detector 10 for measuring the inclination (cant) of the left and right rails (the figure shows a case where it is installed on the rail 20a side, but the rail 2
) is also installed on the 0b side.
Also, on the pillars 4d and 4e, a height displacement detector 12 (the figure shows a case where it is installed on the reference measurement rail 20b side, but the rail (similarly installed on the 20a side) is also installed. The feeler 11 is extended toward the reference line 5 through a feeler leveler (not shown) that maintains the horizontal position and corrects the height deviation due to the tilt of the support 4e, and is maintained in constant contact with the feeler 11. Therefore, the height from the top of the rail head to the reference line is adjusted to be the same at the front reference section, rear reference section, and inspection section before work, so the track bed will not fall in the longitudinal direction of the reference rail. If there is an inspection device at the location, the feeler 11 is separated from the reference line 5, so the rail climbing device is activated and the feeler 11 moves up the rail until it comes into contact with the reference line 5. When the feeler 11 comes into contact with the reference line 5, the lifting device stops, and then the anti-reference gauge is leveled and the tamping device compacts the ballast trackbed on the lower surface of the sleeper, completing the level adjustment of the straight section of the track. do. In the figure, the feeler 11 is brought into contact with the reference line 5 from below, but the supports 4d and 4e are provided with arms extending above the reference line 5, and the feeler 11 is brought into contact with the reference line 5 from this arm.
It may also be made to hang down and come into contact with.

Note that the struts 2d, 2e, 3d, 3e, 4d, and 4e are movable in the vertical direction and restrained in the left-right and front-rear directions by guide tubes (not shown) fixed to the vehicle body 15.

FIG. 2 shows a wiring diagram of the overflow signal generator used in the present invention.

In other words, since the rear part of the car body is in an area that has already been leveled, the reference level 6 installed here is 0 on the straight part of the rail,
A signal proportional to the set cant is output for a circular curve section, and a signal proportional to the set cant is output for a gradient changing section such as a transition curve connecting a straight line section and a curved section.

The output from the reference level device 6 is input to the terminal B of the level correction mechanism 9, which drives the servo motor SM to rotate the reference bar 9 and hold the horizontal rod 8 horizontally or at a set cant. Therefore, the leveling displacement detector 10 detects the height difference between the left and right rails. That is, the output of the potentiometer 21 that outputs a voltage proportional to the amount of rise of the anti-standard rail 20a with respect to the standard rail 20b whose height deviation has been corrected, that is, the set cant amount, and the output A of the leveling displacement detector 10. are compared by the comparator 22, and the anti-reference side rail 20a is lifted up by the lifting device so that the difference voltage becomes O.

Thereafter, the ballast trackbed on the underside of the sleepers is compacted using a tamping device, and the level adjustment of the curved section of the track is completed. In the figure, A1 to A3 are for signal level adjustment, respectively.

In the embodiments described above, a reference wire is also used as the reference line and a feeler is used as the reference line sensing means.
Instead of these, a light source is provided in the front reference section, and the light beam emitted from this light source forms a reference line, and a reference line sensing means is constructed with a light receiver provided in the rear reference section and a slitter provided in the inspection section. You can also. As is clear from the above description, according to the leveling inspection device of the present invention, the amount of lift required for track alignment is continuously calculated while running on the rail, and the amount of lift required for track alignment is calculated continuously while the rail is running, and The leveling of the anti-reference rail with respect to the reference rail can be performed at the same time.

In addition, the reference level is installed at the rear of the car body where it is not affected by the vibrations of the tamping device, and the signal from this reference level is used to control the horizontal rod via the level correction mechanism.
The effects are great, such as being able to perform more accurate straightening work quickly.
