Description
Technical Field
The utility model belongs to the technical field of steel pipe production is relevant, more specifically says, relates to a steel pipe production measurement alarm device.
Background
The steel tube has a hollow cross section with a length much greater than the diameter. The steel pipe is divided into round, square, rectangular and special-shaped steel pipes according to the shape of the cross section; the steel pipe is divided into a carbon structural steel pipe, a low-alloy structural steel pipe, an alloy steel pipe and a composite steel pipe according to the material quality; the steel pipes are divided into steel pipes for conveying pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment and the like according to the application; the production process includes seamless steel pipe and welded steel pipe, the seamless steel pipe includes hot rolling and cold rolling (drawing), and the welded steel pipe includes straight seam welded steel pipe and spiral seam welded steel pipe.
Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, but also are economical steels. The steel pipe is used for manufacturing the building structure net rack, the supporting column and the mechanical support, so that the weight can be reduced, the metal can be saved by 20-40%, and the industrialized mechanized construction can be realized. The steel pipe is used for manufacturing the highway bridge, so that steel can be saved, the construction is simplified, the area of a coating protective layer can be greatly reduced, and the investment and the maintenance cost are saved.
In an automatic steel pipe or steel plate processing production line, detection and confirmation of the conveying position and the length of a steel pipe are necessary means for automatic production, and particularly, sensors of front and rear processing equipment of a large-sized steel pipe such as a large straight seam steel pipe forming machine need to accurately detect the length of the steel pipe so as to determine the moving position of the steel pipe and provide input signals for the automatic equipment. In the prior art, when the length of the steel pipe is detected, the passing time of two end faces of the steel pipe is detected through two sensors, and the length of the steel pipe is calculated by multiplying the passing time by the moving speed of the steel pipe, but the steel pipe does not always advance at a constant speed in the moving process, so that the measured length of the steel pipe is wrong.
A new way for measuring the length of a steel pipe is explained in the journal of the measurement of the steel pipe, and a steel pipe length measuring system has various length measuring ways and has various characteristics. (1) And measuring the length by a grating ruler. The basic principle is as follows: two grating rulers with fixed lengths are respectively arranged on the outer sides of two ends of the steel pipe, a rodless cylinder is utilized to drive the grating rulers to be close to the two ends of the steel pipe, and the measurement of the length of the steel pipe is realized by utilizing the interference phenomenon of light. Its advantages are high measuring accuracy. However, the grating ruler is expensive and difficult to maintain, and is sensitive to the influence of dust and field vibration, and under the working condition of workshop fields, the influence of dust in the air, vibration generated in the process of conveying the steel pipe and the like is difficult to avoid, and the grating ruler has large measurement error and even cannot be used in serious conditions. (2) And measuring the length by a camera. The camera length measuring method is to utilize image processing to realize the length measurement of steel pipe and has the principle that one section of the steel pipe conveying roller way is provided with a series of equidistant photoelectric switches, and the other section is provided with a light source and a camera. When the steel pipe passes through the area, the length of the steel pipe can be determined according to the position of an image shot by a photoelectric switch at a certain position on a screen through a camera. The method is characterized in that online measurement can be realized, and length data can be obtained when the steel pipe passes through a length measurement area without interruption. The defects exist that: if the special light source is not used for irradiation, the steel pipe is interfered by external light, and after the special light source is adopted, because the brightness of the pipe end of the steel pipe is high after chamfering, the reflection of light is strong, the reflection of light is generated on a camera, the resolution ratio of the limit of the pipe end is reduced, reading errors are easily caused, and meanwhile, errors exist in the detection of the photoelectric switch, so that the actual measurement precision is also low. (3) And (5) measuring the length by an encoder. With the wide application of the encoder, the research of length measurement by using the encoder appears, namely, a hydraulic cylinder pushing length measurement method. The principle is that an encoder is arranged at an oil cylinder, the oil cylinder is used for pushing a steel pipe to move on a roller way, a series of photoelectric switches are arranged on the other side of the oil cylinder at equal intervals, and when the end of the steel pipe pushed by the oil cylinder touches the photoelectric switches, the recorded reading of the encoder is converted into the stroke of the oil cylinder, so that the length of the steel pipe can be calculated. The method is characterized in that the steel pipe needs to be lifted up during length measurement, and the mechanical part for pushing the steel pipe has a huge structure and higher manufacturing cost. In addition, a certain error also exists in the detection of the photoelectric switch; in order to realize repeated measurement, a driving roller and a control part thereof are additionally arranged, so that the manufacturing cost of the system is increased.
