Description

TECHNICAL FIELD The present invention relates to a gauge straightener for railway rails, and more particularly to a gauge straightener suitable for a turnout.

Each part of the rail is frequently subject to distortion and deformation due to repeated train loads as the train runs, and various rail displacements such as gauge displacement, level displacement, elevation displacement, etc. can occur in the rails. When these rail displacements increase, the oscillation of the train running on the rails increases, which not only deteriorates ride comfort but also impairs running stability. In order to avoid this situation, we must constantly monitor the status of rail displacement through daily patrol inspections and periodic inspections using inspection vehicles, and promptly and appropriately correct defective areas to ensure that they are always in good condition. need to be kept in condition.

Therefore, a small and lightweight gauge adjuster has been proposed that adjusts the distance between the left and right rails by placing it over the left and right rails and rotating a jack-like mechanism (for example, see Patent Documents 1 and 2). .

<How to use the gauge adjuster 1 according to the embodiment of the present invention>
Next, a method of using the gauge corrector 1 according to the embodiment of the present invention configured as described above will be explained with reference to the drawings.

(When performing gauge adjustment of crossing section Rs of turnout)
When performing gauge adjustment at the crossing portion Rs of a turnout, the reference side gauge adjustment body 11 side is usually a basic rail (stock rail), so as shown in Fig. 1 etc., the reference side gauge adjustment body 11 side is Catch the head of the rail R using the rail catch part 11b.

On the other hand, the slide side gauge straightening body 12 side becomes the crossing part Rs of the turnout as shown in FIGS. Since the rail catch attachment part 14b cannot be used, two first sub-rail catch bodies 13 are used for the sliding gauge straightening body 12 to straighten the gauge at the crossing part Rs of the turnout, as shown in FIG. Attach it according to the area where correction is to be performed.

Specifically, the three through holes 13b21 of the pair of upright mounting plates 13b2, 13b2 of the first sub-rail catch mounting portions 13b of the two first sub-rail catch bodies 13 are connected to the slide-side gauge straightening body 12. Align the through-holes 12c1 of a plurality of mounting plates 14b2, 14b2 (for example, 17 as shown in FIG. Fit the width of the crossing portion Rs of the turnout through a fixing member such as a bolt.

Therefore, depending on the location of the crossing point Rs of the turnout, the intersecting rails R are close to each other, making it difficult to catch the rails. However, in this embodiment, the two first secondary Using the rail catch bodies 13, 13, 17 through holes 12c1 of the slide side gauge straightening body 12 are arbitrarily selected, and the rail head side contact portions 13a1, 13a1 of the first sub-rail catch bodies 13, 13, respectively. This can be done by changing the spacing between the two.

Then, when the fixation of the two first sub-rail catch bodies 13, 13 is completed according to the width of the crossing portion Rs of the turnout, the worker grasps the handle portion 11d2 of the reference side gauge straightening body 11 and rotates it. Then, the threaded rod 11c is rotated in one direction, and the slide side gauge adjustment body 12 is moved closer to or away from the reference side gauge adjustment body 11 by the rotation of the threaded rod 11c, thereby performing gauge adjustment.

(When performing gauge adjustment at a location other than the crossing section Rs of the turnout)
When performing gauge adjustment at a location other than the crossing portion Rs of the turnout, the reference side gauge adjustment body 11 side is usually the basic rail (stock rail), so as shown in Fig. 1, etc., the gauge adjustment body 11 side is Catch the head of the rail R using the rail catch part 11b.

On the other hand, even if it is a turnout, the slide side gauge straightener 12 side is the same as the normal rail R like the reference side gauge straightener 11 side, as shown in FIGS. 1 and 2. The second auxiliary rail catch body 14 is attached to the side gauge straightening body 12.

Specifically, out of the ten through holes 13b21 of the pair of upright mounting plates 14b2, 14b2 of the second sub-rail catch body 14, all through holes 13b21 or, for example, three or four through holes 13b21 are used. Then, from among the 17 through-holes 12c1 provided on the left and right side surfaces 12c, 12c of the slide-side gauge adjustment body 12, align the positions of 10 through-holes 12c1 that match the portion where gauge adjustment is to be performed, and press the pin. Alternatively, the second auxiliary rail catch body 14 is fixed at an arbitrary position with respect to the slide side gauge straightening body 12 by passing bolts or the like and fastening them with nuts if necessary.

When the attachment of the second sub-rail catch body 14 to the slide side gauge straightening body 12 is completed, the worker grips and rotates the handle portion 11d2 of the reference side gauge straightening body 11 to move the threaded rod 11c in one direction. Gauge adjustment is performed by moving the slide side gauge adjustment body 12 closer to or away from the reference side gauge adjustment body 11 by rotating the threaded rod 11c.
