3 results about "Leveler" patented technology

The utility model discloses an underwater disc leveler which comprises a pull rod, a first cutting disc group, a second cutting disc group, a protective telescopic connecting rod assembly and a leveling roller group, the rear end of the pull rod is hinged with the first cutting disc group, and the first cutting disc group is connected with the second cutting disc group through the protective telescopic connecting rod assembly. The second cutting disc group is fixedly connected with the leveling roller group; each cutting disc group comprises a plurality of discs mounted on a transverse sleeve rod of the cutting disc group; the protection telescopic connecting rod assembly is located between the first cutting disc set and the second cutting disc set, and the first cutting disc set is controlled to steer within a certain range after being stressed through stretching out and drawing back. Longitudinal shear stress can be generated on a soil body to loosen a shallow-point soil layer, horsepower generated when a ship drags is reduced, energy is saved, and the shallow-sweeping working quality and working efficiency are enhanced by being matched with a rear roller set to work in a combined mode. And the risk of deformation and damage of the leveler is effectively avoided.

This invention discloses a method and system for determining the proper position of a grounding switch, belonging to the field of power system operation and maintenance technology. The method involves: acquiring a grounding switch operating torque dataset, the model of the field cabinet, and operating sound data; if the operating sound data meets preset sound triggering conditions and the field cabinet model does not belong to a preset cabinet database, then several first slopes are acquired based on the aforementioned dataset; if any of the first slopes is less than a preset threshold, then dynamic trough values ​​and real-time grounding switch operating torque datasets are acquired; if any of the real-time grounding switch operating torque data is less than the dynamic trough value, then the grounding switch operating torque data after rotation and the torque difference are acquired and verified; if both conditions are met, then the status of the grounding switch indicator light and the image of the grounding switch mechanical position are acquired; if both conditions are met, then the grounding switch operation is confirmed to be in place. This invention provides a method for determining the proper position of a grounding switch through the linkage of multi-dimensional information, enabling accurate judgment of the grounding switch's position status.

To dispense with exchange of a workpiece and a cleaning member.SOLUTION: In a cleaning method of a roll leveler 1, in the state where a belt-like cleaning member 91U is sandwiched between a row of upper work rolls 12 and a first upper pad 21U on its upper side, the upper work rolls 12 are wiped with the cleaning member 91U by sending the cleaning member 91U in the row direction of the upper work rolls 12, or by rotating the upper work rolls 12.SELECTED DRAWING: Figure 1
