Description

An Automatic Vertical Laser Altimeter Leveling Ruler

technical field

The utility model relates to a measuring tool, in particular to an automatic vertical laser level gauge.

Background technique

Leveling, also known as "geometric leveling", is a method of measuring the height difference between two points on the ground with a level and a leveling rod. Place a level between two points on the ground, observe the leveling rod erected on the two points, and calculate the height difference between the two points according to the reading on the ruler. Usually starting from the leveling origin or any known elevation point, the elevation of each point is measured station by station along the selected leveling route. Because the level planes at different elevations are not parallel, the height difference between two points measured along different routes will be different. Therefore, when sorting out the national leveling results, necessary corrections must be made according to the normal height system adopted to obtain the correctness. the elevation.

The leveling rod is a ruler used in leveling measurement, and its quality directly affects the accuracy of leveling measurement. Therefore, the standard ruler must not only be made of high-quality wood, but also require a stable ruler length and accurate division; the commonly used leveling rulers include tower rulers and double-sided leveling rulers. Observations introduce errors of a systematic nature. During precision leveling work, the leveling standard should be erected on a special foot pad and pile with a certain weight to keep the leveling staff in a vertical position. Adjust the angle, more can not adapt to various environments such as slopes.

detailed description

As shown in Figure 1-4, an automatic vertical laser altimetry leveling rod is used in conjunction with a laser rangefinder to ensure measurement accuracy. The automatic vertical laser altimeter leveling rod includes a retractable tripod 1 and a retractable tripod 1 is installed with a rotating disk 2, the rotating disk 2 is a hollow ring structure, and a slide rail 3 is connected inside. The slide rail 3 is provided with a sliding mechanism 4 that can be adjusted horizontally and vertically. The rotating ball 5 of rotation is provided with a level gauge 6, and the lower end is connected with a vertical adjustment weight 7 at the upper end of the rotating ball 5.

The outriggers of the telescopic tripod 1 are conical, and each outrigger is formed by socketing two upper and lower joints and connecting them by locking bolts. This ensures stability in non-flat environments such as slopes.

The rotating disk 2 has a fixed disk 8 and a movable disk 9, wherein the fixed disk 8 is provided with a steel ball installation groove 10 and a positioning groove 11, and the movable disk 9 is rollingly connected with the fixed disk 8 by steel balls and is positioned and locked by a positioning ring 12. tight. Therefore, it can be conveniently rotated freely and adjusted to an angle convenient for people to observe.

The sliding mechanism 4 includes a horizontal carriage 13 on which a longitudinal sliding seat 14 is arranged. Both the horizontal slide frame 13 and the longitudinal slide seat 14 are provided with threaded rods, the rotation of the horizontal knob drives the horizontal threaded rod to rotate, the rotation of the horizontal threaded rod drives the horizontal slide frame 13 to move horizontally, and the rotation of the vertical knob drives the rotation of the vertical threaded rod , the longitudinal threaded rod rotates to drive the longitudinal sliding seat 14 to move longitudinally, so that the leveling rod can be adjusted conveniently to align with the ruler pad, the zeroing speed of the instrument measurement can be accelerated, and the measurement accuracy can be improved.

A level ruler 15 is also installed on the rotating disk 2 . Thereby, the horizontal installation accuracy of the leveling rod can be adjusted, which not only ensures the stability during measurement, but also improves the measurement accuracy.

The rotating ball 5 is installed in the ball pair of the longitudinal sliding seat 14 through a steel ball. Thus, 360° rotation can be realized, and the automatic vertical adjustment can be adapted to environments such as flat land, grassland, muddy land, and slopes, which is convenient for field measurement and investigation.

A laser range finder is installed at the lower end of the vertical adjustment weight 7, and the laser range finder is used to measure the distance to the ground ruler pad 16. In this way, gravity can be used to realize automatic adjustment, and at the same time, the distance can be directly measured, which reduces the labor intensity of measurement and improves work efficiency.

Working principle and process:

The first step: the staff first puts the level gauge 6 into the level gauge fixing frame, fixes the level gauge 6 by fixing the level gauge fixing nut, and adjusts the level gauge 6 through the horizontal carriage 13 and the longitudinal sliding seat 14, so that the level gauge 6 Align the ruler pad 16.

Second step: the staff regulates the telescopic tripod 1 by observing the horizontal air bubble in the spirit level 15, and can adjust the rotating disc 2 to adjust the level simultaneously, as long as it is adjusted to the horizontal position, the fixing nut for the telescopic tripod is fixed.

Step 3: The worker makes the leveling rod 6 align with the observer by rotating the rotary disk 2, and fixes the leveling rod fixing nut at the same time.

Step 4: Install a vertical adjustment weight 7 under the leveling rod fixed frame. After the leveling rod fixed frame is installed, the vertical adjustment weight will automatically adjust the vertical to achieve the purpose of aligning the laser rangefinder with the ruler pad 16.

Step 5: At this time, the staff can observe the data L1 of the leveling rod and the fixed distance of the instrument, and then according to the data L2 of the laser range finder, the data L required for measurement is equal to the data L1 plus the data L2 plus the fixed distance of the instrument.
