Description

A marker pole for a spirit level

technical field

The utility model belongs to the field of measurement, in particular to a signpost used for a spirit level.

Background technique

In the shipbuilding process, levelness measurement is an important inspection item for hull construction accuracy. The equipment usually used for levelness measurement is a level, which usually includes two parts: a level body and a ruler. When measuring, first place the level on the tripod, then level the level, place the ruler vertically on the first measurement point, rotate the level so that the laser emitted is aligned with the ruler, and read the coordinates of the laser point on the ruler , then place the ruler vertically at another measuring point, rotate the level so that the laser emitted by it aligns with the ruler, read the coordinates of the laser point on the ruler, and subtract the two coordinate values to get the level difference between the two measuring points.

There is a deficiency in the use of this level, that is, although the levelness of the level can be adjusted, it is difficult to control the verticality of the scale when the scale is set up, and the scale can only be controlled vertically to the measurement plane by the measurer's vision. Due to the inability to effectively control the verticality of the ruler, a certain deviation occurs during the horizontality measurement, which affects the accuracy of the measurement. Taking the commonly used measuring scale with a height of 1.5m as an example, when the scale rod is tilted by 5°, there will be a deviation of 6mm when the laser projection reads the coordinates on the scale, and the deviation of 6mm is unacceptable in the levelness measurement of the hull structure.

Contents of the invention

Aiming at the problems existing in the prior art, the utility model provides a marker pole used for a spirit level, which can ensure the vertical erection of the scale and improve the accuracy of levelness measurement.

In order to achieve the above object, the utility model adopts the following technical solutions:

A marking pole for a spirit level, the marking pole comprises a pole body, a scale line is arranged on the pole body along the length direction of the pole body, a bracket is arranged on the side wall of the pole body, and one end of the bracket is fixed on the pole body 1. The other end is provided with a support frame, and a bubble level is embedded in the support frame, the support frame is set horizontally, and the panel surface of the bubble level instrument panel and the scale line are set parallel to each other.

The supporting frame is a circular hollow frame.

The bubble level is a circular bubble level.

The accuracy range of the circular bubble level is ±2°.

The inner diameter of the circular hollow frame is equal to the outer diameter of the circular bubble level.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model is simple in structure and easy to use. The dial surface of the bubble level instrument panel and the scale line are arranged parallel to each other. The bubbles in the circular bubble level are used to indicate the level. By observing the position of the bubbles in the circular bubble level, the circular bubble can be adjusted. The level of the spirit level, so as to adjust the level of the scale line on the rod body, so as to ensure that the laser position emitted by the level gauge can be accurately determined by reading the scale line, which can overcome the lack of verticality of the existing level gauge scale, and can effectively distinguish the scale during use The angle of inclination can be easily adjusted, which is conducive to ensuring the vertical establishment of the scale and improving the accuracy of levelness measurement.
