How to control the assembly accuracy of the vertical and horizontal spirals of the track moving spiral unloader to ensure smooth operation and reduce wear?

When discussing the assembly accuracy control strategy of vertical and horizontal spirals in our company's track mobile spiral unloader (taking the ATXL-B series as an example), it is necessary to first mention our company's deep foundation of 20 years in the research and manufacturing of environmentally friendly and efficient equipment. Over the past 20 years, we have not only accumulated rich technical experience, but also achieved significant achievements in the innovation and design of spiral unloaders and transfer station series equipment, becoming the drafting unit of the industry standard JC/T 2575 "Bulk Cement Spiral Unloader". This honor is not only a recognition of our technical strength, but also an important driving force for promoting industry progress.
The Importance of Assembly Accuracy Control
For rail mobile spiral unloaders, the assembly accuracy of vertical and horizontal spirals directly affects the operational stability, efficiency, and service life of the equipment. High precision assembly can ensure uniform force distribution during the rotation of the spiral body, reduce unnecessary vibration and wear, thereby improving overall unloading efficiency and reducing maintenance costs. Therefore, our company has adopted multiple advanced technologies and strict quality control measures in this process.
Assembly accuracy control of vertical spiral
Precision machining and testing: The manufacturing of vertical spirals begins with high-precision CNC machining equipment, ensuring that key parameters such as geometric dimensions, pitch, and helix angle of the spiral blades meet design requirements, and strict testing is carried out through precision testing equipment such as coordinate measuring machines to ensure machining accuracy reaches the micrometer level.
Dynamic balance correction: When the spiral body rotates at high speed, if there is an imbalance phenomenon, it will cause severe vibration and affect the stability of the equipment. Therefore, before assembly, we will perform dynamic balance correction on the spiral body by adding counterweights or adjusting the blade distribution to achieve the best balance state during rotation.
High precision bearings and seals: High quality and high load-bearing capacity bearings are selected, combined with precision sealing devices, to ensure that the spiral shaft is stable and sealed during rotation, preventing material leakage and bearing wear.
Installation positioning technology: Advanced laser positioning technology and precise installation fixtures are used to ensure the accurate installation position of the vertical spiral in the equipment, and the clearance between the driving device, support structure and other components meets the design requirements.
Assembly accuracy control of horizontal spiral
Modular design: The horizontal spiral part adopts modular design, which is convenient for assembly and maintenance. Each module undergoes rigorous testing before leaving the factory to ensure stable and reliable performance. During the assembly process, precise docking devices and positioning pins are used to ensure tight connections and accurate positioning between each module.
Flexible connection technology: In order to reduce the impact of vibration and shock on the horizontal spiral, we use flexible connection technology such as elastic couplings, shock absorbers, etc. to effectively absorb and isolate vibration, protect the spiral body and transmission system.
Synchronous drive control: The horizontal spiral drive system adopts advanced synchronous control technology to ensure that multiple spiral bodies can maintain consistent speed and phase when working simultaneously, avoiding vibration and wear caused by speed differences.
Intelligent monitoring and adjustment: Integrated intelligent monitoring system, real-time monitoring of the operating status of the spiral body, including parameters such as speed, temperature, vibration, etc. Once an abnormality is detected, the system can automatically sound an alarm and prompt adjustment plans to ensure that the equipment is always in optimal working condition.
