Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgical processing equipment, in particular to a lifting support rail used for a steel billet elevator. Background Art
[0002] In the high-speed wire rod production process, billet charging methods are generally divided into two modes: cold charging and hot charging. For cold-charged billets (bill temperatures below 400°C), the processing process usually involves the billets being stacked on the ground and directly charged into the furnace for rolling. In contrast, hot-charged billets (temperatures of 400°C and above) adopt a more efficient process path, that is, after being produced by the steel plant's continuous casting machine, they are directly transported to the billet elevator via billet hot delivery rollers. The temperature of such hot-charged billets is often as high as 650°C, and the heat carried by the billets is used for subsequent heating furnace charging operations, significantly reducing the use of gas for heating in the heating furnace, thereby significantly saving energy consumption and becoming an effective strategy for reducing the production cost of rolled products.
[0003] However, the billet elevator, a critical piece of equipment used to transport hot-charged billets to a 5-meter-high platform (the standard height of a wire rod production line) for loading into the furnace, directly impacts the temperature maintenance of the hot-charged billets and the efficient operation of the entire production line. Currently, elevators generally utilize a chain drive, but this transmission method is strictly restricted by the chain's bite angle. When the chain's bite angle fluctuates due to external factors such as billet quality and length, it can easily cause jamming between the chain and sprocket. In severe cases, it can even lead to chain breakage, preventing the billets from being lifted smoothly and forcing them to pile up, causing production interruptions and increased maintenance costs. It also causes the temperature of the hot-charged billets to drop, impacting hot charging efficiency and product quality.
[0004] In summary, the chain drive system of the existing billet elevator is not adaptable enough when faced with changes in billet parameters, and is prone to failures such as jamming or chain breakage. This not only affects the equipment's operating efficiency and increases the maintenance burden, but can also disrupt the temperature management of hot-charged billets, thereby negatively impacting the energy-saving and consumption-reduction goals of the entire high-speed wire production process. Therefore, there is an urgent need to develop a new structure that can effectively control the chain's operating trajectory and ensure that the chain drive's bite angle varies within a reasonable range, thereby improving the elevator's operating stability and reducing the equipment's failure rate. This will ensure smooth lifting and temperature maintenance of hot-charged billets, thereby effectively controlling production costs. Utility Model Content
[0005] In order to make up for the above-mentioned shortcomings, the utility model provides a lifting support rail for a billet elevator, which effectively solves the problem of chain and sprocket jamming caused by changes in the chain running trajectory (bite angle) of traditional elevators under the influence of factors such as billet quality and length, ensures the smooth operation of the elevator and reduces the equipment failure rate.
[0006] The utility model is realized through the following technical scheme: a lifting rail for a steel billet elevator, comprising a support rail arranged on an elevator unit and a lifting chain cooperating with the support rail, and its technical points are: a lifting rail base for fixing the support rail is provided at the lower part of the support rail, the lifting rail base comprises a fixed base arranged parallel to the support rail and a rail base support foot for supporting the fixed base; a guide plate assembly for the running stability of the lifting chain is provided on the lifting rail base, the guide plate assembly comprises guide plates symmetrically arranged on the right sides of the fixed base and a U-shaped reinforcement plate connected to the guide plate and the fixed base.
[0007] Furthermore, there are multiple guide plate assemblies, which are arranged at intervals on the lifting rail base.
[0008] Furthermore, the front and rear ends of the guide plates on both sides are combined into a dovetail shape.
[0009] Beneficial effects and features of the utility model:
[0010] Improve operational stability: By adding guide plates on both sides of the lifting rail base, precise control of the lifting chain's running trajectory is achieved, ensuring that the chain drive bite angle is always within a controllable range, effectively avoiding transmission jams caused by abnormal bite angles, significantly improving the overall operational stability of the elevator unit, reducing equipment failure rates, and ensuring continuous and efficient operation of the production line.
[0011] Extending equipment life: The dovetail-shaped guide plate inlet and outlet effectively prevents the chain from scraping against the guide plate during operation, reducing wear on the chain and guide plate, extending the service life of key components, reducing equipment maintenance costs and replacement frequency, and improving the overall economic efficiency of the equipment.
[0012] Easy Installation and Maintenance: The guide plate is innovatively divided into two sections for full-weld installation, which not only solves the difficulty of welding long guide plates, but also evenly distributes the front, middle, and rear sections of the lifting rail base, enhancing the rationality of the equipment structure and the ease of assembly. Furthermore, the reinforcement plate enhances the guide plate's ability to resist lateral forces, preventing deformation during operation, ensuring long-term stable operation of the equipment and simplifying subsequent maintenance.
[0013] Energy saving and emission reduction: By improving the operating stability of the elevator, the forced stacking and reheating of steel billets due to equipment failures are reduced, unnecessary energy waste is avoided, and it helps enterprises achieve green production.
[0014] Stable hoist operation is conducive to maintaining the high temperature state of hot-charged steel billets, avoiding the temperature drop of steel billets due to equipment failure, ensuring the smooth progress of the hot charging process, maximizing the use of the thermal energy of the steel billets themselves, greatly reducing the consumption of gas in the heating furnace, further enhancing the energy-saving effect of the hot charging process, and strongly supporting the goal of reducing costs and increasing efficiency in rolled product production.
