Description

Measurement apparatus for separation error of power transmission tower posts using laser pointer}

The present invention relates to a laser pointer angle measurement error measuring instrument for 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, while reducing the construction time and inspection time and accurate construction of the steel tower Anyone who can handle the optical wave without the need for two people when measuring the angle error can provide a laser pointer angle error measuring instrument for a transmission tower easier to use because it can measure the angle error alone.

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.

In order to solve this problem, a standard measurer for measuring the rotational error of the pylon column member is registered. Looking at the configuration, the front part is cut and has a contact surface of a certain width, and the width of the triangle is gradually increased from the rear to the front. A measurer body is provided, and a narrow measuring surface having a ruler that is symmetrical to the left and right at the rear of the measurer body is formed, and a centerline drawn vertically along the upper surface of the measurer body from the ruler zero point of the measuring surface. 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.

The present invention is to solve the problems as described above, by measuring the angle of error of the steel tower casting material more easily during the construction of the steel tower, it is possible to provide a precise construction of the steel tower while reducing the angle of construction and inspection time, angle of error Anyone who can handle the optical wave without the need of two people at the time of measurement can measure the angle error by itself from time to time, so the purpose is to provide a laser pointer angle error measuring instrument for easier transmission tower.

In order to achieve the above object, the present invention is a vertical contact line section and a horizontal contact line section having a 90 degree right angle so that the plane can be in close contact with the inner surface of the angle-type iron tower base material having a vertical plane and a horizontal plane forming a 90 degree right angle in a square shape. Are formed respectively, and a vertical cutting surface is formed at the center of the diagonal direction of the corner where the vertical contact line section and the horizontal contact line cross section are formed, and the ruler is formed in a cross shape at the left and right sides at the center of the vertical cutting plane, and the vertical contact line on the upper surface. An N-shaped operation protrusion having a sliding hole is formed on the cross-section and the horizontal contact end face. The sliding hole has an A-shaped contact ring wound on the upper and lower sides of the vertical part, and a contact curved bar having an external thread on the horizontal end part. A sliding ring is fastened to the outer thread of the end of the horizontal part, so In the inner periphery of the sliding long hole tip, there is a through hole through which the horizontal part of the close contact ball bar penetrates, and a stopper stopper which is fastened and fixed is fixedly installed.In the sliding long hole, the close contact bar has elasticity between the stopper stopper and the sliding ring. An inner surface measuring frame each having an elastic spring pulled therein;

As such, the present invention can more easily measure the angle error of the cast iron tower during the construction of the steel tower, thereby reducing the construction time and inspection time, and providing accurate steel tower construction. Anyone who can handle the light wave without it can measure the angle of error from time to time alone, making it easier to use.
