The invention relates to a split line moving platform. A power transmission lead is used as a working path in the platform, various barriers (a vibration damper, a crimping pipe, a spacing bar, a suspension line clamp, an insulator string and the like) are spanned and avoided, the platform is provided with a camera which can observe the condition of the running line and timely discover the defects of the line and hardware tools, and other working mechanical arms can be expanded to finish clearing line barriers and the like. A robot has flexible action and large working range, has the effect of protecting devices during jumping the barriers, and has high safety and reliability. The platform mainly consists of a traveling device, a driving arm device, an anti-tilting device and a power supply control box; and the traveling device is arranged on an electric cable and connected with the driving arm device, and the anti-tilting device is arranged at the tail end of the traveling device.

The invention is an imaging method and device for visual inspection of the surface quality of a hot cylindrical long material. The imaging device includes a plurality of imaging units, a control system and a synchronous adjustment mechanism. Through the synchronous adjustment mechanism, the outer diameter of the cylindrical long material is controlled by the size of the outer diameter of the cylindrical long material. The system calculates the position parameters that the imaging unit needs to adjust, and the synchronous adjustment mechanism realizes the automatic adjustment of the imaging unit. The invention can detect the surface quality of different types of cylindrical long products for the same unit, and the visual inspection system can adjust the position of the imaging unit according to the outer diameter of the cylindrical long products, so that the distance between the image sensor and the surface of the cylindrical long products can be kept constant, so as to obtain Stable high-quality images, so as to achieve stable online inspection of the surface quality of hot cylindrical long products, timely detection of surface defects of cylindrical long products, reduce the occurrence of batch defects, and improve the yield.

The invention discloses an automobile chute locking device, which comprises a base frame, a rotating piece and a trigger frame; it is characterized in that a number of fixing holes are opened on the body of the base frame, and a folded part connected with the body is formed, and the rotating piece is connected by An open rivet is movably riveted under the folding part, and the open rivet is covered with a torsion spring; the rotating piece is fixedly riveted with a long axis and a zipper rivet, and the riveted part of the long axis protrudes from the rotating piece; the trigger frame is also movably riveted on the aforementioned folding part On the trigger frame, there is a buckle groove, and the riveted part of the aforementioned long axis is pressed into the buckle groove. It is directly fixed on the sliding core and moves synchronously with the sliding core, and cooperates with the stopper in the chute to stop the sliding core, so there is no coordination error between the sliding core and the sliding core can be stopped conveniently and quickly at any time. And it has two braking mechanisms, which improves the practicability of this type of automobile chute locking device, and also overcomes the shortcoming that the failure of one braking structure leads to the failure of the entire automobile chute locking device.

The invention discloses a method and system for automatically identifying roll eccentricity based on the rolling force of hot-rolled strip steel. The method includes: acquiring rolling force fluctuation data of the rolling mill along the length direction of the strip steel; calculating the circumference of each roll according to the roll diameter Interval rolling force fluctuation data; calculate the similarity of the rolling force fluctuation data in the adjacent two roll circumference intervals; score the calculated similarity according to the standard threshold to obtain the roll eccentricity state score, by combining the roll eccentricity state score with The preset threshold value is relatively large to determine whether there is roll eccentricity. The invention can calculate the similarity information of the rolling force fluctuation in the strip length direction in real time, automatically judge whether there is roll eccentricity in the rolling mill according to the recognition algorithm, and provide a data basis for the timely discovery of the rolling mill roll defects on the production site.
