Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a low-stress conduction mechanism for processing torsional resistance cables used in wind turbines. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. It uses anti-torsion cables to transmit electrical energy. When processing anti-torsion cables, a conduction device is required to transport and guide them.

[0003] The existing low-stress transmission mechanism for processing torsional resistance cables for wind turbines has a simple structure and no limiting or locking structure. The cables are easily twisted during transportation, and the stress during twisting will cause deformation of the cables. Therefore, a low-stress transmission mechanism for processing torsional resistance cables for wind turbines is proposed. The cables are limited and locked by an auxiliary concave core wheel and a third concave core wheel driven by a second screw, preventing the cables from bending without affecting them, thereby reducing the chance of stress generated during cable transportation. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides a low-stress transmission mechanism for processing torsional resistance cables for wind turbines. The cable is limited and clamped by an auxiliary concave core wheel and a third concave core wheel pushed by a second screw, preventing the cable from bending without affecting it, thereby reducing the chance of stress generated during cable transportation.

[0005] The technical solution adopted by the utility model to solve its technical problem is a low-stress transmission mechanism for processing torsional resistance cables for wind turbines, comprising a frame cover, wherein a second concave core wheel is equidistantly connected to the inside of the frame cover through bearings, an inner end of the frame cover located on one side of the second concave core wheel is rotatably connected to the first concave core wheel through a bearing, a reduction motor is installed on one side of the frame cover through a mounting frame, a pressing assembly is provided on the top of the frame cover, and the pressing assembly includes an internal threaded sleeve welded to the top of the frame cover, a first screw is sleeved through the internal threaded sleeve, the bottom end of the first screw located inside the frame cover is connected to the first structural frame through a bearing, and the two ends of the first structural frame are rotatably connected to the pressing wheel through a shaft;

[0006] The bottom of the frame cover is provided with a telescopic assembly, and the telescopic assembly includes a base plate fixed to the bottom of the frame cover by bolts, and connecting rods are sleeved through both ends of the bottom plate, one end of the connecting rod is connected to the frame through a threaded groove, and the bottom of the frame is rotatably connected to an auxiliary concave core wheel through an axle rod, and clamping assemblies are provided on both sides of the frame, and the clamping assembly includes a second screw connected to both sides of the frame through a threaded groove, and one end of the second screw located inside the frame is connected to a second structural frame through a bearing, and the inside of the second structural frame is rotatably connected to a third concave core wheel through a shaft rod.

[0007] By adopting the above technical solution, the first screw is rotated to push the pressing wheel downward, pressing the cable onto the first concave core wheel. The reduction motor drives the first concave core wheel to rotate and push the cable to move and transport it. The second screw is rotated to push the third concave core wheel to clamp the cable on the auxiliary concave core wheel to limit and guide it.

[0008] Specifically, two ends of the top of the first structural frame are connected to first auxiliary rods through threaded grooves, and the first auxiliary rods pass through the frame cover.

[0009] Specifically, the output shaft on one side of the reduction motor is fixedly connected to one end of the first concave core wheel through a connecting sleeve.
