Description

A measuring ruler for the horizontal axis of a rotary kiln

technical field

The utility model relates to a horizontal axis measuring ruler for a rotary kiln, which relates to a static measuring tool for the axis of a rotary kiln used in metallurgical and chemical processes, such as alumina, building materials, nonferrous metals, and metallurgical industries.

Background technique

The straightness of the cylinder axis of the rotary kiln is the key to the stable operation of the equipment. The static measurement of its axis is a traditional measurement method. There are manual measurement and calculation method, kiln measurement method with theodolite outside the kiln and laser kiln measurement method inside the kiln. Manual measurement of each component has large data errors, and the laser kiln measurement method in the kiln is suitable for installation and measurement of new kilns. At present, the static measurement of the axis of the rotary kiln mainly uses the kiln measurement method with theodolite outside the kiln. It calculates the horizontal and vertical deviation of the cylinder center of each support position by measuring the external coordinates of the rolling rings at each support position of the rotary kiln.

When measuring the horizontal axis, in the horizontal direction of the side of the rotary kiln, take the line of sight of the theodolite about 1 meter away from the outermost point of the horizontal direction of the rolling ring, and be close to parallel to the kiln axis. Use a ruler to read the distance between the outermost point of the rolling ring and the line of sight at each gear distance. According to the measured data such as the horizontal distance of each gear, the outer diameter of the rolling ring and the distance of each gear, and taking the center of the cylinder of gear I as the reference, the deviation of the horizontal axis of the cylinder center of each supporting gear is calculated.

Due to the large outer diameter of the rotary kiln rolling ring, the measurement of the outermost point in the horizontal direction usually adopts the method of hanging a hammer in the circumferential direction of the rolling ring, and uses a ruler to read the distance between the hanging hammer line of each gear and the line of sight. The hammer line fluctuates in the wind, and the ruler 0 is located on the hammer line to make it overlap by sight, and the ruler is horizontally skewed and other factors. cause measurement errors. In addition, it is time-consuming and labor-intensive to hang the wire hammer on the rolling ring of each gear, and there is also a deflection phenomenon.

Contents of the invention

The purpose of this utility model is to provide a measuring ruler for the horizontal axis of a rotary kiln that can effectively improve the measurement accuracy, is convenient to operate, and saves time and effort for the above-mentioned shortcomings of the prior art.

The purpose of this utility model is achieved through the following technical solutions.

A measuring ruler for the horizontal axis of a rotary kiln is characterized in that its structure includes:

A vertical ruler - the vertical ruler is a straight rod-shaped ruler, on which there is a pendulum needle whose upper end is fixed on the vertical scale; the vertical scale below the pendulum needle is engraved with a horizontal scale whose axis position is 0 degrees ;

Level ruler—one end of the level ruler has an inner ring matching with the shape of the vertical ruler, which is vertically slidingly sleeved and connected with the vertical ruler.

The utility model relates to a measuring ruler for the horizontal axis of a rotary kiln, which is characterized in that a pressing screw is arranged on the leveling ruler collar at the sliding joint of the leveling ruler and the vertical ruler.

The utility model relates to a measuring ruler for the horizontal axis of a rotary kiln. It is characterized in that the level is provided with a long cavity filled with liquid, and the long cavity is filled with a spirit level containing air bubbles in the liquid.

The utility model relates to a measuring ruler for the horizontal axis of a rotary kiln, which is characterized in that the vertical ruler is composed of two stretchable and foldable outer tube rulers and an inner tube inside the outer tube ruler.

The utility model relates to a measuring ruler for the horizontal axis of a rotary kiln. The measuring ruler is composed of a vertical ruler and a horizontal ruler. The vertical ruler is connected by two sections for the convenience of carrying. Vertical ruler. The level is set on the lower part of the vertical ruler and can slide up and down (generally, the sliding amount is not required), but the gap between the sliding sleeve and the vertical ruler is very small, there are fixing screws on the sliding sleeve, and there is a horizontal air bubble on the upper part of the level. A ruler with a scale, the scale is fixed at 500mm-1500mm according to the measurement range to ensure that the theodolite can directly read the data. The horizontal axis measuring ruler of the utility model replaces the combination of the traditional pendant hammer and the straightedge. When the vertical ruler is higher than the outermost point in the horizontal direction of the rolling ring and is close to the outer diameter of the rolling ring and is vertical, the horizontal ruler replaces the straightedge to measure Simple and convenient, with little error.

Detailed ways

A measuring ruler for the horizontal axis of a rotary kiln, the structure of which comprises:

A vertical ruler 1—the vertical ruler is a straight rod-shaped ruler, and a pendulum needle 2 whose upper end is fixed on the vertical scale is provided on the vertical ruler; horizontal scale;

Level 3—one end of the level has a ring with an inner ring matching the shape of the vertical ruler, and is connected with the vertical sliding sleeve of the vertical ruler; Compression screw 4; the level is provided with a long cavity filled with liquid, the long cavity is filled with a level 5 containing air bubbles in the liquid; It is composed of an inner tube located inside the outer tube ruler.

During operation, after the theodolite is set up, connect and fix the upper vertical ruler and the lower vertical ruler. The vertical ruler is higher than the outermost point in the horizontal direction of the rolling ring and is close to the outer diameter of the rolling ring. The lower part of the vertical ruler is supported on a stable plane, and Make the pendulum needle on the lower vertical ruler set to 0 position, that is, the vertical ruler is vertical; if necessary, adjust the height of the level ruler through the sliding sleeve so that it is within the line of sight of the theodolite (because the theodolite can adjust the line of sight up and down, the level ruler generally does not need to adjust the height), Adjust the level to make the horizontal bubble center, and fix the sliding sleeve screw. At this time, the theodolite can be used to read the distance between the outermost point of the rolling circle of this gear and the line of sight. The rotary kiln is 90 per revolution ^. Measure each gear once, measure four times in total, and calculate the average value, which is more accurate.
