Description

Angle of error measuring instrument for transmission pylon {Apparatus for separation error using transmissiontower posts}

The present invention relates to an angle measurement error measuring device for power transmission tower, and more specifically, by measuring the angle error of the steel tower casting material more easily during the construction of the steel tower, to reduce the construction time and inspection time and provide accurate steel tower construction. It can be, and anyone who can handle the optical wave without the need of two people when measuring the angle error, and it is related to the angle error measuring instrument for the transmission tower easy to use because it can measure the angle error alone by itself.

In general, steel towers constructed for the construction of transmission towers are angle-grid structures in which high-voltage cable connecting members are installed to fasten a plurality of angles with bolts and connect high-voltage cables to the top of the steel tower. It takes a lot of time and effort.

In addition, four pillars supporting the steel tower are built into the ground at the bottom of the steel tower, which is called steel tower shell material, and the steel tower can be stably installed without any errors when the steel tower shell material is correctly placed.

That is, according to the related regulations, the angle of error of the steel tower casting material must satisfy the standard value within ± 1mm of the design value, but this standard value is unclear, and the standard error length of rotating the steel tower casting material is the center error length of the tip of the steel tower base material. Although the length of the angle varies according to the specification of the steel base material, the error rate of rotation angle per 1 mm for each steel base material standard is generated up to 2 times.

On the other hand, in the conventional measurement method of the angle error, the distance measurement is measured by measuring the distance from the instrument to the base of the iron tower every day, and the measurement of the height difference is a staff of the cross section used for level measurement and stadia survey ) Was measured.

However, the measurement method of the angle error is very cumbersome and cannot be measured alone, so the person measuring the instrument and the person measuring the tape measure and the staff should always measure the angle error in a pair of two.

And a reference point is displayed at an upper end of the center line to match the reference point with the center point of the pylon base material, thereby measuring whether the center point of the pylon base material and the center line of the measurer body coincide.

However, this method of measuring the angle of error of distance is very troublesome to measure and the error is not accurate, and only the measurement of the rotational error is possible, so the measurement of the distance from the instrument to the pylon base material has to be measured with a tape measure. There was this.
