Description

The present invention relates to a gauge straightener that is used when laying or repairing railway rails and adjusts the gauge displacement (including track displacement) of the rail to an appropriate state.

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). .

When the length, the mounting position of the index plate 11d on the movable rod main body 11b, the mounting position of the index indicator plate 13f on the telescopic mechanism 13, the length of the threaded rod 13b, etc. are completed, the rail R whose gauge should be adjusted, The rail catch main bodies 11b2 and 12b2 of the rail catch parts 11b and 12b at the outer ends of the movable rod part 11 and the fixed rod part 12 are placed on top of R.

At that time, if the gauge G of the rails R, R is a normal gauge G _C , the distance W1 between the rail inner abutting plate part 11b22 and the rail outer abutting plate part 11b23 of the rail catch body 11b2, 12b2 is , is formed larger than the width W2 of the head of the rail R, and as shown in FIG. If so, L1+L4+W1=G _C +W2 of the above equation (3) holds true.

Therefore, in this case, for example, as shown in FIGS. 11(a) and 11(b), the rail inner abutting plate parts 11b22, 12b22 and the rail outer abutting plate parts 11b23, 12b23 of each rail catch part 11b, 12b, respectively. Since it is possible to set and remove the rail catch body parts 11b2 and 12b2 without contacting the inside and outside of the rail R and R heads, respectively, the work efficiency of gauge adjustment can be improved. .

(When adjusting gauge by pushing rails R and R from inside to outside)
However, as the gauge adjuster 1 according to the embodiment of the present invention is rolled on the rails R, R, for example, the gauge G of the rails R, R becomes narrower than the normal gauge G _C , such as 1067 mm. For example, as shown in FIGS. 12(a) and 12(b), when the heads of the left and right rails R and R are biased toward the rail inner contact plate portions 11b22 and 12b22 of the rail catch portion bodies 11b2 and 12b2, for example, In this case, it becomes necessary to widen the rails R and R from the inside to the outside to adjust the gauge.

In FIG. 13(a), the gauge G of the rails R, R is narrower than, for example, the normal gauge G _C , and as shown in FIGS. The position indicated by the index indicating portion 13f1 at the tip of the index indicating plate 13f in the index plate body 11d1 of the index plate 11d in a state where the heads of the rails R and R are in contact with the inner surfaces of the contact plate portions 11b22 and 12b22, respectively. An example is shown. FIG. 13(a) shows a state in which the gauge G of the rails R, R is approximately 6 mm narrower than the normal gauge G _C , for example.

Therefore, the tool connecting part 13e of the telescopic mechanism part 13 is rotated to extend the space between the movable rod part 11 and the fixed rod part 12, and the rail catch part bodies 11b2, 12b2 of the left and right rail catch parts 11b, 12b are rotated. The rail inner contact plate parts 11b22, 12b22 are brought into contact with the inner sides of the rails R and R heads, respectively, so that the indicator indicator part 13f1 at the tip of the indicator indicator plate 13f indicates the 0 position or indicator of the gauge 11d2 for gauge widening. Push the rails R and R outward from the inside until they match the normal gauge indication line 11d11 for gauge widening carved on the plate body 11d1.

As shown in FIG. 13(b), the indicator indicator part 13f1 at the tip of the indicator indicator plate 13f indicates the 0 position of the gauge 11d2 for gauge widening, or the normal gauge indicator for gauge widening engraved on the indicator plate body 11d1. If it matches the line 11d11, it means that the width of the gauge G has been widened by around 6 mm, and G= _GC .

Therefore, the relationship L1+L2=G _C =G, which is the above equation (1), is established, and the gauge G at that point matches the normal gauge G _C , such as 1067 mm, and the gauge correction is completed.

As a result, according to the gauge adjuster 1 of the embodiment of the present invention, the worker can determine whether the index indicating portion 13f1 of the index indicating plate 13f is at the 0 position of the gauge 11d2 for gauge widening on the index plate 11d or when the gauge is widening. Gauge adjustment can be performed by operating the expansion/contraction mechanism section 13 so as to position the rail at the normal gauge line 11d11 and widening the distance between the pair of rail catch sections 11b and 12b.

(When adjusting gauge by pushing rails R and R from inside to outside)
When the rails R, R are rolled by the rollers 11b31, 12b3 on the outside of the rail catch parts 11b, 12b and moved to the next gauge adjustment point while traveling, the gauge G of the rails R, R is set to a predetermined gauge such as 1067 mm. If there is a part that is wider than G _C , the rail catch bodies 11b2 and 12b2 of the rail catch parts 11b and 12b are placed on the left and right rails R and R as shown in FIGS. 14(a) and 14(b). It becomes necessary to correct the gauge by pulling the rails R, R from the outside to the inside and narrowing the rails so that they are biased toward the contact plate portions 11b23 and 12b23.

The position indicated by the index indicating portion 13f1 at the tip of the index indicating plate 13f in the index plate body 11d1 of the index plate 11d in a state where the heads of the rails R and R are in contact with the inner surfaces of the contact plate portions 11b23 and 12b23, respectively. An example is shown. FIG. 15(a) shows a state in which the gauge G of the rails R, R is about 5 mm wider than the normal gauge G _C , for example.

Therefore, the tip of the power tool is fitted into the tool connecting part 13e of the telescopic mechanism part 13 and rotated, and the rail catch part main body 11b2 of the rail catch part 11b, 12b is rotated as shown in FIGS. , 12b2 are brought into contact with the outsides of the rails R and R heads, respectively, so that the index indicating portion 13f1 at the tip of the index indicating plate 13f is set to 0 of the gauge 11d3 for narrowing the gauge. The rails R, R are pulled from the outside to the inside until they match the position or the normal gauge indicator line 11d12 for gauge narrowing carved on the indicator plate body 11d1.

As shown in FIG. 15(b), the indicator indicator part 13f1 at the tip of the indicator indicator plate 13f indicates the 0 position of the gauge 11d3 for narrowing the gauge, or the normal gauge indicator for narrowing the gauge carved on the indicator plate body 11d1. If it matches the line 11d12, it means that the width of the gauge G has been narrowed by around 5 mm, and G= _GC .

Therefore, the above equation (2), L1+L3+2・W1=G _C +2・W2, is established, and the gauge G at that point matches the normal gauge G _C , such as 1067 mm, and the gauge adjustment is completed. become.

As a result, according to the gauge adjuster 1 according to the embodiment of the present invention, the worker can check the scale indicated by the index indicating portion 13f1 of the index indicating plate 13f on the index plate 11d, the normal gauge indicating line 11d12 for narrowing the gauge, etc. Gauge adjustment can be performed by operating the telescoping mechanism section 13 while referring to , and pulling the movable rod section 11 toward the stationary rod section 12 to contract the distance between the pair of rail catch sections 11b and 12b. can.

Then, when the index indicating portion 13f1 at the tip of the index indicating plate 13f matches the 0 position of the gauge 11d3 for narrowing the gauge or the normal gauge indicating line 11d12 for narrowing the gauge carved on the indicator plate body 11d1, the rail R, The gauge adjustment is completed when the distance R matches the normal gauge _GC , such as 1067 mm. Therefore, the train moves to the next gauge adjustment point.

(When gauge adjustment at a certain location is completed and moving to the next gauge adjustment location)
When gauge adjustment at a certain location is completed and the gauge adjustment device 1 is moved to the next gauge adjustment location, the gauge adjustment device 1 according to the embodiment of the present invention has rollers on the outside of the rail catch parts 11b and 12b, respectively. Since 11b31 and 12b3 are provided, it is possible to move while rolling the rails R and R.
