Specific implementation
[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model.
[0022] Referring to Figures 1-3 An embodiment provided by the utility model: a high -level anti -line passes money ring structure of cold -rolled ribbed steel bar production, including high pay -off stand 1, high pay -off stand 1 is one of the main body support structure of whole device, high pay -off stand 1 is internally provided with multiple sliding slots 6, and the sliding slot 6 is the structural part for pulley 5 to provide sliding track, and high pay -off stand 1 side wall is provided with lifting trolley assembly, and high pay -off stand 1 bottom is provided with guide assembly, and the guide assembly is used for guiding lifting trolley,
[0023] The lifting trolley assembly includes side plates 4, which are mainly used for lateral protection and positioning of the bucket frame 7 and other components. It can prevent the bucket frame 7 from shifting or swaying in the horizontal direction, ensuring stable transmission of internal materials (such as steel bars). Multiple side plates 4 are arranged inside the high pay-off rack 1, and each side plate 4 is rotatably connected with a pulley 5 inside the sliding groove 6 of the high pay-off rack 1. The pulley 5 is one of the key components for vertical displacement of the lifting trolley assembly. The pulley 5 is slidably connected inside the sliding groove 6, and the side plate 4 is fixedly connected with an inclined support plate one 2, which plays a role in strengthening and stabilizing the connection in the structure. It connects the side plate 4 and the support platform 3, and through the inclined design, it can effectively transfer the force borne by the side plate 4 to the support platform 3. The inclined support plate one 2 is fixedly connected with the support platform 3 at the top, and the support platform 3 is an important load-bearing platform that provides stable support for the bucket frame 7 and other components. The support platform 3 is provided with the bucket frame 7 at the top. The guide assembly includes a bottom plate 8 fixedly connected to the bottom of the high pay-off rack 1. The outer wall of the bottom plate 8 is fixedly connected with multiple outer body support feet 9, which are used to support the outer structure of the high pay-off rack 1, increase the overall stability and anti-overturning ability of the equipment, and are left-right symmetrical relative to the bottom plate 8. The upper surface of the bottom plate 8 is fixedly connected with multiple inclined support plates two 10, which are fixedly connected inside the high pay-off rack 1. The upper surface of the inclined support plate two 10 is fixedly connected with a fixed table 11, and the upper surface of the fixed table 11 is fixedly connected with multiple rotating tables 12, which are left-right symmetrical relative to the inclined support plate two 10. The side wall of the rotating table 12 is fixedly connected with a standard motor 14, and the output end of the standard motor 14 is fixedly connected with a high pay-off rack lower guide wheel 13, which is one of the drive wheels of the synchronous belt 15. It rotates under the drive of the standard motor 14. The high pay-off rack lower guide wheel 13 is rotatably connected inside the rotating table 12, and the outer wall of the high pay-off rack lower guide wheel 13 is slidably connected with the synchronous belt 15. The synchronous belt 15 is a component for transmitting power and motion, which moves under the drive of the high pay-off rack lower guide wheel 13 and drives the lifting trolley assembly to vertically displace through cooperation with the pulley 5.
[0024] Specifically, in the initial state, the lifting trolley assembly is located at a specific position inside the high-rise wire-laying frame 1. When it is necessary to adjust the height of the high-rise wire-laying ring structure, the operator starts the standard motor 14. After the standard motor 14 starts running, it will drive the lower guide wheel 13 of the high-rise wire-laying frame to rotate. Since the lower guide wheel 13 of the high-rise wire-laying frame is rotatably connected inside the turntable 12, and its outer wall is slidably connected to the synchronous belt 15, when the lower guide wheel 13 of the high-rise wire-laying frame rotates, the synchronous belt 15 will start to move under its drive. The pulley 5 is slidably connected to the high-rise wire-laying frame 1. Inside the chute 6, the side plate 4 is connected to the bucket-shaped frame 7 via the inclined support plate 2 and the support platform 3. Under this structural connection, the sliding of the synchronous belt 15 generates a pulling force. This pulling force drives the lifting trolley assembly to move vertically along the chute 6. Through the vertical displacement of the lifting trolley assembly, the precise adjustment of the height of the elevated defense line's cross-ring structure is successfully achieved. This structure adopts a new cross-ring material strategy, abandoning the previous practice of overemphasizing the hardness of the cross-ring material, and instead selecting a highly tough molybdenum-cobalt-nickel-based material to resist impact. This special material, with its excellent toughness, can withstand impacts... When the steel bar swings and generates hammering force, it can effectively absorb and transform these impact forces. Its internal microstructure and chemical bonds undergo a series of changes upon impact, preventing the formation of brittle cracks due to stress concentration on the material surface or inside. This characteristic greatly enhances the impact resistance of the wire guide ring, allowing it to maintain good structural integrity and functionality even under harsh environments of frequent swinging impacts from steel bars. Its durability is significantly enhanced. Wire guide rings made of molybdenum-cobalt-nickel composite materials can achieve more than 50 times the performance of traditional materials. This significant advantage not only greatly reduces the replacement frequency of wire guide rings, reducing the consumption of manpower, material resources, and time costs caused by frequent replacements and lowering equipment maintenance costs, but also effectively ensures the stability of the equipment production process. In the production process of cold-rolled ribbed steel bars, the steel bar transmission link is crucial. Stable and reliable wire guide rings can ensure that the steel bars are transmitted efficiently along the predetermined trajectory and speed, avoiding problems such as interruption, jamming, or deviation in steel bar transmission caused by wire guide ring failure. This lays a solid foundation for the continuity and quality consistency of the entire cold-rolled ribbed steel bar production, promoting the smooth operation of the entire production process and the stable improvement of product quality.
[0025] Working principle: In the initial state, the lifting trolley assembly is located at a certain position within the high-rise wire-laying frame 1. When it is necessary to adjust the height of the high-rise defense line passing ring structure, the standard motor 14 is started. The standard motor 14 drives the lower guide wheel 13 of the high-rise frame to rotate. Since the lower guide wheel 13 of the high-rise frame is rotatably connected inside the turntable 12 and its outer wall is slidably connected to the synchronous belt 15, the synchronous belt 15 starts to move under the drive of the lower guide wheel 13 of the high-rise frame. The pulley 5 is slidably connected inside the slide groove 6 of the high-rise wire-laying frame 1. The side plate 4 is connected to the bucket-shaped frame 7 through the inclined support plate 2 and the support platform 3. Therefore, the sliding of the synchronous belt 15 will drive the lifting trolley assembly to make vertical displacement along the slide groove 6, thereby realizing the adjustment of the height of the high-rise defense line passing ring structure. This structure adopts a brand-new The material strategy for the guide ring no longer emphasizes the hardness of the guide ring material, but instead selects a molybdenum-cobalt-nickel-based material with very high toughness to resist impact. This type of material, with its excellent toughness, can effectively absorb the hammer force generated by the swing of the steel bar, avoiding the formation of brittle cracks, and greatly improving the impact resistance and durability of the guide ring. Practical verification has shown that the service life of guide rings using this material can be more than 50 times that of traditional materials. This not only significantly reduces the replacement frequency of the guide ring and lowers equipment maintenance costs, but also greatly improves the stability of equipment production, ensuring the efficient and reliable operation of the steel bar transmission link in the production of cold-rolled ribbed steel bars, and providing a strong guarantee for the continuity and quality consistency of the entire cold-rolled ribbed steel bar production.
