The invention discloses a cable winding-unwinding tensioning roller. The cable winding-unwinding tensioning roller comprises an outer roller body and an inner roller body, the outer roller body and the inner roller body are connected through a left supporting disc and a right supporting disc, slide grooves are formed between the outer roller body and the inner roller body, and supporting blocks are slidably arranged in the slide grooves; a bidirectional lead screw is rotationally connected between the left supporting disc and the right supporting disc and is provided with a left adjusting block and a right adjusting block, and the left adjusting block and the right adjusting block are hinged to the supporting blocks through connection rods; the left supporting disc is provided with a controller; and the inner side of the left supporting disc and the inner side of the right supporting disc are provided with laser displacement sensors connected with the controller. According to the cablewinding-unwinding tensioning roller, the left adjusting block and the right adjusting block are driven to do opposite or reverse linear motion through rotation of the bidirectional lead screw, accordingly, the supporting blocks are driven to slide, the outer diameter of the roller is adjusted, and meanwhile, the outer diameter of the roller is precisely adjusted through the laser displacement sensors.
Description
technical field [0001] The invention relates to the technical field of electric power construction equipment, in particular to a tensioning drum for retracting and unwinding cables. Background technique [0002] In the laying process of the cable production machine, it is often necessary to use a tensioning roller to quickly wind and release the cable, but the size of the tensioning roller in the prior art cannot be adjusted, and it is necessary to prepare different specifications for cables of different specifications. Tensioning the drum not only reduces work efficiency, but also seriously wastes resources. [0003] The Chinese invention patent with the publication number CN107142788A disclosed on September 8, 2017 an elastic extrusion tensioning mechanism for a special paper coating machine. The upper ends of the two guide rods are connected by a horizontal plate, and the horizontal plate is located On the upper side of the connecting rod, the middle part of the upper en...
