Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a turnout passage mechanism for a portable track inspection device for detecting track deviations on railway tracks.

``Conventional Technology'' In order to operate trains safely and in a comfortable running condition, it is necessary to maintain and manage the tracks so that they are always in good condition.

For this purpose, it is necessary to inspect the track, and there are several ways to do this, such as using a high-speed track inspection vehicle, using a portable track inspection device, and manually.In particular, track inspection at turnouts is difficult. It's done manually.

High-speed track inspection vehicles are mainly used for long track sections, but for small sections such as inside yards, they are either manually inspected or a portable track inspection device is used.

The portable track inspection device is one that is driven manually and automatically performs inspection work, and has a structure as schematically shown in FIGS. 8 and 9.

In FIGS. 8 and 9, 100 indicates a standard beam. FIG. 8 is a view of the portable track inspection device viewed from the bottom side. Three running wheels 101 are disposed on the bottom surface of the street reference beam lOO and move on the tread surface of the rail to be measured 201 to make the street reference beam 100 run along the rail to be measured 201, and the gauge of the PII measurement rail 201 is provided. Surface 201A
Two reference contacts 1 for measuring misalignment that rotate in contact with
02 and the opposite rail 202 from the center of the reference beam 100
The arm 103 that protrudes toward the front, the running wheel 104 provided at the free end of the arm 103, and the spring 105 press against the track surface of the opposite rail 202, and the reaction force of this pressing force causes the misalignment measuring contact 102 to The rail to be measured 201
A spring 10 is attached to the rail surface 201A of the rail to be measured 201 at the center position of the mounting interval between the auxiliary contact 106 to be pressed against the rail surface 201A of the rail 201 and the reference contact 102 for measuring misalignment.
A misalignment detection contact 108 that is elastically pressed by the biasing force of No. 7, and a misalignment detection contact 108 that converts the amount of misalignment into an electrical signal.
and a handle 110 for moving the device.

With such a structure, by manually moving the reference beam 100 over the rail 201 to be measured,
The amount of misalignment between the reference beam 100 and the rail to be measured 201 is output from the sensor 109, and the amount of misalignment is stored in a memory every fixed travel distance based on a detection signal from a distance sensor (not particularly shown). measure.

"Problem to be Solved by the Invention" As described above, the portable track inspection device measures the track surfaces 201A of the rail to be measured 201 and the opposite rail 202.

Since the reference contact 102 for measuring misalignment, the contact 10B for detecting misalignment, and the auxiliary contact 106 run in contact with each other at 202A, there is a drawback that it cannot pass through the branch.

That is, the turnout section usually has a caustic line section M (see FIGS. 3 to 7) through which the flanges of the wheels can pass. This caustic line portion M is the reference contact 10 for measuring misalignment.
2. Misalignment detection contact 108 and auxiliary contact 106
This is a sufficiently long distance compared to the diameter of

Therefore, if you try to pass through the turnout part as it is, the contacts 102, 106, 108 will fall into the caustic line part M,
There is a drawback that it collides with the rail at the end of the caustic line part M and breaks.

Conventionally, track deviations at the turnout cannot be detected, so measurements are temporarily stopped before the turnout, the turnout is manually transported, and measurement begins again from the point where the turnout has been crossed.

In addition, as another conventional method, a contactor 102 is attached to the caustic line portion M.
, 106, 108, etc., from falling, a device may be fitted over the caustic line portion M, and by installing this crossing device, the contacts may be allowed to pass directly through the turnout portion.

Even if the inspection device is manually transported at the turnout, and even if the crossing device is fitted to the caustic line M, it is time-consuming, especially for inspection in a place with many turnouts such as a yard. There is a drawback that it is troublesome.

In addition, especially when a crossing device is fitted to a turnout, there is a drawback that if the crossing device is forgotten to be removed, it could lead to a major accident that could cause the vehicle to derail.

An object of the present invention is to provide a portable track inspection device that can freely pass through a turnout without using a crossing device or the like, and can accurately measure track deviations in the turnout. .

(Means for Solving the Problems) In this invention, a roller for passing a missing line portion is provided between each of the reference contact for measuring misalignment of the passing reference beam and the contact for detecting misalignment of the passing reference beam, and An auxiliary beam parallel to the opposite rail is provided at the free end of the arm, auxiliary rollers for passing through the missing line are provided at both ends of the auxiliary beam, and guide rollers are provided before and after the reference contact for measuring misalignment.
The guide roller is configured so that the reference contact for measuring misalignment can ride on the end of the caustic line portion.

According to the structure of the present invention, when the reference contact for measuring misalignment approaches the missing line portion of the rail to be measured, the roller for passing the missing line provided on the reference beam engages with the track surface of the rail to be measured. To prevent a reference contact for measuring misalignment from falling into the caustic line.

When the reference contact for measuring misalignment passes through the caustic line and approaches the other rail, the guide roller first contacts the track surface of the rail, and then the reference contact for measuring misalignment touches the track surface of the rail to be measured. You will be guided on board.

Therefore, the reference contact for measuring misalignment can pass through the caustic line portion without receiving any impact when passing through the caustic line portion.

A limiter is provided on the contact for detecting misalignment. This limiter prevents the misalignment detection contact from protruding significantly into the caustic line when passing through the caustic line.

As a result, the deviation detection contact can be shallowly engaged with the end of the rail and ride on the rail after passing through the arrow line portion, and can pass through the caustic line portion without receiving a large impact.

On the other hand, the auxiliary contact side is equipped with an auxiliary beam and auxiliary rollers at both ends of this auxiliary beam, and when the auxiliary contact passes through the caustic line, the auxiliary rollers connect to the track surfaces of the rails on both sides of the caustic line. . As a result, the auxiliary contact can pass through without falling into the caustic line portion, and when engaging the corner of the rail, the auxiliary contact can return to the track surface of the rail.

"Embodiment" FIG. 1 shows an embodiment of the present invention. Figure 1 shows each contact 102°106.108 when the track inspection device is viewed from the top side.
FIG.

In this invention, the passing reference beam lOO is provided with rollers 301 and 302 for passing through the missing line portion. The mounting position of the rollers 301 and 302 for passing through the missing line portion is the passing reference beam 100.
The center position is selected to be an intermediate position between the center position and the reference contact 102 for measuring misalignment.

In the illustrated example, the rollers 301 and 302 are installed a little closer to the center than the center between the center of the beam 100 and the reference contact 102 for measuring misalignment.

Reference beam 100 for rollers 301 and 302 for passing through missing line parts
The mounting position with respect to the axis of the reference contact 1 for measuring misalignment.
It is located inside the line LS connecting the contact surface with the rail of 02. The distance δ from the line LS is selected to be larger than the maximum possible value of the arrow between the string connecting the reference contact 102 for measuring misalignment and the rail 201 to be measured.

A guide roller group 303 is provided before and after the reference contact 102 for measuring misalignment. This guide roller group 303 is a line L that gradually moves away from the track surface 201A of the rail 201 to be measured, centering on the reference contact 102 for measuring misalignment.
Arrange along L and RL.

By arranging them along the lines LL and RL, when passing through the caustic line portion M, the guide roller furthest from the reference contact 102 rides on the rail at the end of the caustic line portion M for guidance. It is possible to pass through the caustic line portion M without giving an impact.

Furthermore, in the present invention, a limit means 310 is provided on the contact 108 for detecting misalignment. This limit means 310 prevents the misalignment detection contact 108 from thickening (falling) into the caustic line portion M due to the biasing force of the spring 107 when the misalignment detection contact 108 passes through the caustic line portion M. However, it is provided to prevent the contactor 10B from receiving a large impact when riding on the rail at the end of the caustic line portion M.

As the limit means 310, a protrusion 112 such as a pin is formed on the shirt l-111 that movably supports the detection contact 10, and this protrusion 112 is engaged with a metal fitting 113 that supports the shaft 111 to perform the limit operation. It can be configured to:

Furthermore, in this example, guide fittings 114 are provided with oblique surfaces before and after the detection contact 10B, and when riding on the rail from the caustic line portion M, the detection contact 108 is guided by the guide fitting 114 onto the track surface 201A of the rail to be measured. Let them guide you.

On the other hand, an auxiliary beam 304 parallel to the opposite rail 202 is provided on the free end side of the arm 103, and auxiliary rollers 305 for passing through the missing line portion are provided at both ends of the auxiliary beam 304.

This auxiliary roller 305 for passing through the missing line portion also has an auxiliary contact 106.
It is provided at a position further away from the track surface 202A of the rail 202 so as not to interfere with the measurement of misalignment.

In addition, FIG. 1 shows a case where two auxiliary contacts 106 are arranged in parallel. In addition, guide rollers 3 are provided on both sides of the auxiliary contact 106.
06 is provided, and this guide roller 306 guides the auxiliary contact 106 to the track surface of the rail when entering and exiting the caustic line portion M, thereby suppressing the occurrence of impact.

The operation of the portable track detection device according to the present invention will be explained using FIGS. 3 to 7. In FIG. 1, the rollers and contacts painted black refer to the state in which they are in contact with the rail.

Figure 3 shows the state in which the track measuring device approaches the caustic line M of the turnout (in this state, it is used to measure misalignment)! Both E semi-contactors 102A and 102B are in contact with the rail 201 to be measured.

FIG. 4 shows a state in which the preceding contact for measuring deviation 102A has entered the caustic line portion M. In this state, the roller 301 for passing through the missing line portion and the reference contact 102B for measuring misalignment are in contact with the rail 201 to be measured. When the missing line passage roller 301 comes into contact with the rail 201 to be measured, the preceding reference contact for misalignment measurement 102A moves to the caustic line portion M.
It is prevented from falling off and can pass through the caustic line portion M.

FIG. 5 shows a state H in which the misalignment measuring contact 108 passes through the caustic line M. In this state, the measuring contact 108
is apart from the rail 201 to be measured, but its protrusion amount is regulated by the limit means 310 described above.

FIG. 6 shows a state in which the rear reference contact 102B is passing through the caustic line portion M. In this case, the preceding reference contact 102A and the roller 302 for passing through the missing line are connected to the measured rail 2.
01 and prevents the reference contact 1[) 2B from falling into the caustic line portion M.

FIG. 7 shows a case where a caustic line portion M exists on the opposite side rail 202. FIG. Since one side is in contact with the opposite rail 202,
The auxiliary contactor 106 is prevented from falling into the caustic line portion M, and can return to the track surface of the rail 202.

"Effects of the Invention" As explained above, according to the present invention, the trajectory can pass through the caustic line portion M formed in the turnout, thereby making it possible to continuously measure the trajectory deviation of the turnout. An inspection device can be provided. Therefore, track deviations can be easily detected even in a yard with a large number of turnouts, the time required for inspection can be shortened, and less manpower is required, and the effect is extremely large in practical use. It is.
