Description

[Detailed explanation of the invention] This invention was designed to set up a straight track that is easy to handle even for general workers without surveying experience, and has good accuracy so that work can be carried out efficiently. This relates to gauges for use.

Conventionally, when setting the trajectory, surveying equipment such as transits and levels were used by tools with sufficient surveying experience and proficiency. The current situation is that it is impossible to carry out the work, and it is difficult to secure working tools with sufficient survey experience.In addition, especially when setting high-speed tracks, the edge of the subgrade concrete 1 is A pedestal 2 is installed at each of the reference point a and the rail tread in the section (the right end in the drawing).
The surrounding concrete 5 and the elastic sleepers 6 are laid so that the bubble (not shown) of the level C of the gauge 4 on which the slider 3 is placed is located at the center (0 position). In the curved section shown in Figure 2, in order to provide a cant when laying the rail, the pedestal 2 is held perpendicular to the reference point a, while the slider 3 is placed on the rail tread to remove the air bubbles from the level C. □
” position, an error of e (in mm units) will occur on the pedestal 2 side with respect to the specified value, but this error e will be a maximum of 2 mm on an extended straight track for high-speed vehicle operation.
It is necessary to keep it within the allowable value.

However, in order to keep the error e within the allowable value (2 mm) of the lever, it is important to first improve the accuracy of the cage itself, and when handling it, it is possible to carry out the work easily and efficiently. is also requested.

Therefore, this invention aims to overcome the current situation as described above and provide a gauge that can be handled by general workers, especially a gauge for setting a straightening and straightening track, which is suitable for setting a straightening and straightening track. A guide pipe is perpendicularly fixed and fixed, and a height scale with a height scale that can be fixed at a predetermined position is passed through the guide pipe so as to be able to rise and fall, and also along a separate scale carved near the other end of the upper azure. A slider that can be fixed at a predetermined position and movable is fitted to the upper rail, rotatably supported by a support shaft below the slider, and in the middle of the roller that is to be in contact with the rail tread,
The rail head guide is tiltably held between the support shafts, and a coil spring is tensioned and interposed between the upper surface of the horizontal frame portion of the rail head guide and the lower surface of the slider.

An embodiment of this invention will be described below with reference to FIGS. 3 to 7. One end of a hollow top 11 with a substantially square cross section and a spirit level l provided in the middle (FIGS. 3 and 4) A hollow guide tube 12 with a substantially square cross section is fixed to the left side and the right side is the other end, and a height 13 is fitted into the guide tube 12 so as to be able to rise and fall. The height scale 13 can be stationary and held at a predetermined position with respect to the guide pipe 12, and a height scale i is engraved on the upper side of the height scale 13, while the lower part is made of roadbed concrete (Figs. 1 and 2). "1" of
) is attached to a seat p with an inverted U-shaped recess that can be set and held at a reference point S.

In addition, an auxiliary plate 14 is attached to orthogonally intersect the upper casing 11 and the guide pipe 12, and also for reinforcement.

A slider 15 is covered and fitted to the other end of the upper cassette 11 so as to be movable from side to side, and a window W provided at the center upper surface of the slider 15 allows the separation scale m engraved on the upper cassette 11 and the slider 15 to be connected to each other. The zero line can be visually seen, and the slider 15 can be stopped and held in a predetermined position relative to the upper slider 11 by a knob g on one side of the slider 15. The hollow connecting body 16 is integrally fixed by welding.
A support shaft d is horizontally suspended and supported below the arm pieces u, u of an inverted U-shaped support 17 that hangs down and is integrally welded to the lower end of this connecting body 16, and both ends are fixed with studs. Kimono j
The rollers 1B, 1B are rotatably fitted to the support shaft d, and the middle of the horizontal portion n of the inverted U-shaped rail head guide 19 is passed through and loosely fitted to the support shaft d. At the same time, a coil spring 21 is tensioned and interposed between the upper surface of the horizontal frame part n and the lower end surface of the slider 15 and also within the connecting body 16, so that the rail head guide 19 is always moved by the roller 18.
It is a force to be energized on the side.

The outer peripheral edge of the roller 18 is brought into line contact with the tread t of the head of the rail R, and the horizontal part n of the rail head guide 19 is sandwiched between the rollers 1B, 1B. , and is tiltably supported on a support shaft d.

Insulating materials y and z having a slippery surface such as vinyl chloride are attached to the inner wall surfaces of the transparent conduit 12 and the slider 15, respectively, so that the height 13 and the slider 15 can move smoothly.

In the figure, 7 is the upper rail of the gauge 4, 20 is the elastic sleeper, K is the vertical distance from the reference point a to the upper surface of the upper rail 7 when using the gauge 4 in a straight section, g is the reference plane V at the head of the rail R is the rail These are the legs of the head guide 19.

Since this device has the above-mentioned configuration, the catch plate P below the height/lower height 13 is engaged with and held at the reference point S, while the rail R
When placing the roller 1B in the center of the tread t,
Adjust the height 13 so that the bubble of the level l is located in the center.
is raised and lowered in the guide tube 12, and when the bubble is located at the center, the height scale 13 is fixed to the guide tube 12 with the knob f, and the height of the elastic sleeper 20 is determined by reading the height scale i. The amount of adjustment can be determined.

Further, the slider 15 is moved to the left or right with respect to the upper rim 11, the roller 18 is placed in the center of the tread t of the rail R, and the roller 18 is placed in contact with the center, and then the slider 15 is fixed to the upper rim 11 with the knob g, and then the window W The slider 15 leaves the zero line position via the scale m
By reading this, you can calculate the "deviation" of the setting position of the rail R with respect to the elastic sleeper 20, so move the rail R to the left or right by an amount equivalent to the "deviation" and adjust the rail R in the left-right direction. The correct setting position can be determined.

In this way, the rail R can be set at an appropriate position on the elastic sleeper 20 in both the vertical and horizontal directions.

In addition, when deciding to separate, the leg part v of the rail head guide 19
, one side of v (right leg in Figures 4 and 7)
is brought into contact with the reference surface g of the head of the rail R to hold the rail head guide 19 at a constant position with respect to the rail.

According to this invention, a height scale with a scale for height and a height can be fitted into a guide tube that is perpendicular to and integral with a guide tube with a separate scale so that it can be raised and lowered, and can be held in a predetermined position, and a slider can be attached to a guide tube that is integrated with the upper scale with a separate scale. Since the rails can be fitted so that they can be moved laterally and held in place, the position of the rails relative to the elastic sleepers can be adjusted using a spirit level and rollers depending on the situation in the area where the rails are to be installed, such as across straight or curved sections. In addition, the rail head guide is held between the rollers in the middle of the rollers so as to be tiltable on the support shaft of the slider so as to make contact with the rail. Since a coil spring is tensioned and interposed between the rail head guide and the rail head guide, the rail head guide is always springing and biased toward the roller side, so the setting position of the rail head guide relative to the rail head surface can be adjusted smoothly and easily. It is very convenient for workers to handle, and it also corrects the bottleneck that had previously forced reliance on surveying work by skilled surveyors, making it easier for ordinary workers who are not proficient in surveying. By visually checking the scale, you can immediately see whether the calculated value is within the tolerance range, so you can set the trajectory, especially the bullet hole trajectory, without feeling particularly complicated, and it is easy to operate. In addition to being simple, there is no danger that the overall structure will become complicated, so it has practical benefits such as being robust and inexpensive to manufacture.
