Abstract
The utility model relates to a blast furnace chute inclination angle detection system, which comprises a laser distance measuring instrument, a horizontal instrument and a tripod, wherein the tripod is arranged in a blast furnace maintenance manhole position, the laser distance measuring instrument is connected with the horizontal instrument, the horizontal state of light rays sent out by the laser distance measuring instrument is ensured, the tripod is connected with the horizontal instrument, and the upward and downward movement of the laser distance measuring instrument along the parallel line of the center line of a blast furnace is ensured.
Description
Technical field
The utility model relates to a kind of detection system of utilizing the trigonometrical function principle to measure the blast furnace chute inclination angle.
Background technology
In blast furnace was produced, the accuracy that the distributor chute inclination angle is adjusted was not only relevant with the levels of precision of tilting mechanism in the airtight box, and relevant with the geometrical shape of chute itself.Chute in use is subjected to the continuous impact and the friction of furnace charge, and chute can be out of shape by thermogenesis when producing in the rugged environment in addition, thereby causes the angle of chute cloth to change, and then influences blast furnace operating.Though master control room can reflect the angle of inclination of chute in real time, chute deforms and can cause the cloth angle deviation to occur in process of production.Therefore, need to proofread and correct the value at chute inclination angle in process of production, but, directly measure comparatively difficulty, usually adopt indirect method to measure aborning because chute is suspended on the blast furnace furnace roof.
At present, the chute measurement of dip angle mode that generally adopts on the blast furnace is to be a weight on a protractor, and protractor vertically is placed on blast furnace maintenance manhole place, and the square edge of protractor adjusted to the direction that is parallel to chute, read the value at chute inclination angle according to the weight position.Because the throat diameter of blast furnace is bigger, especially for large blast furnace, adopt this method to measure, the one, square edge that can't the ensuring amount hornwork is parallel to chute, the 2nd, field condition can influence the direction of weight during operation, and human factor and extraneous factor all can influence measuring result.Find that by on-the-spot test use this method to measure the chute inclination angle and exist than mistake, its deviation is usually between 1.5-2.5 °.
Summary of the invention
In order to overcome existing measuring method operational difficulty, affected by environment easily, problems such as measuring result out of true, it is little to the utility model proposes a kind of volume, easy and simple to handle, the chute measurement of dip angle system that adaptive capacity to environment is strong.This detection system is measured convenient, can be installed in the extremely narrow and small blast furnace maintenance manhole front space in space, solve measure blast furnace chute inclination angle installation space and position must strict restriction problem.
The utility model provides a kind of blast furnace chute inclination angle detection system, it comprises water level gauge, tripod, and laser ranger, tripod places blast furnace maintenance people hole site, laser ranger links to each other with water level gauge, guarantee the light level that laser ranger sends, tripod links to each other with water level gauge, guarantees that laser ranger moves up and down along the parallel lines of blast furnace medullary ray.
The utility model also provides a kind of blast furnace chute inclination angle detection system, comprise water level gauge, tripod, and laser ranger, wherein tripod places blast furnace maintenance people hole site, laser ranger links to each other with water level gauge, guarantee the light level that laser ranger sends, tripod links to each other with water level gauge, guarantee that laser ranger moves up and down along the parallel lines of blast furnace medullary ray, the inclination angle detection system can further include linear displacement transducer, is used to obtain the distance that laser ranger moves up and down.
The utility model provides a kind of blast furnace chute inclination angle detection system, it comprises water level gauge, tripod, and two laser rangers, wherein tripod places blast furnace maintenance people hole site, two laser rangers all are fixed on the tripod, and the vertical range that is maintained fixed, laser ranger links to each other with water level gauge, guarantees the light level that laser ranger sends.
The laser ranger of above-mentioned any one blast furnace chute detection system can further include the nitrogen cooling apparatus, and the nitrogen refrigerating unit inserts the laser ranger rear portion, is used for laser ranger is cooled off.

Fig. 2 is that embodiment 3 chute inclination angle detection systems use synoptic diagram.
In the drawings, 1. laser ranger, 1 '. laser ranger, 2. tripod, 3. water level gauge, 4. blast furnace maintenance manhole, 5. blast furnace chute.
Embodiment
Need measure respectively when using chute inclination angle detection system laser ranger different positions and blast furnace chute apart from a and b, and the vertical range c between two measuring positions, according to the trigonometrical function principle:
Calculate the angle between the parallel lines of chute and blast furnace medullary ray.
The beneficial effects of the utility model are, can measure easily the blast furnace chute inclination angle, the use laser range finder can reduce the error in the operating process, improve measuring accuracy, simultaneously, this detection system conveniently moving can change for the actual conditions of production scene the position of measuring instrument, further guarantees the reliability of measurement result.
