Structure and working principle of rigid chain elevator
Main structure: The rigid chain elevator is mainly composed of one or more rigid chains, driving devices, guiding devices, and load-bearing platforms. Among them, the rigid chain is the core component, with a special connection and gravity located at the center of the geometric body, ensuring the stability of operation. The driving device is usually composed of a motor and gears, providing power for the movement of the chain. The guiding device is used to guide the direction of movement of the chain and the load platform, ensuring a smooth lifting process.
Mechanical rigid chain elevator
Working principle: By rotating the driving device, the connecting rods on the rigid chain undergo relative motion, thereby changing the height of the load-bearing platform. Taking the Jinli elevator as an example, when the motor drives the gear to rotate, the rigid chain meshing with the gear will make linear motion in the vertical direction. The vertical guide located in the drive box provides support and optimization for the entire chain queue, and locks the link to achieve smooth lifting and lowering of the load platform.
feature
Safe and reliable: It has the characteristic of strong self-locking during shutdown, avoiding the static sinking hazard of hydraulic lifting platform. For example, in the event of a sudden power outage or equipment failure, a rigid chain elevator can immediately lock the chain to prevent the load platform from accidentally descending, ensuring the safety of personnel and goods.
Smooth operation: Multiple sets of rigid chains can achieve synchronous operation, avoiding the differences in hydraulic system multi cylinder operation and having good synchronization. On some large industrial production lines, multiple rigid chain elevators can work together with high synchronization accuracy, ensuring smooth production processes.
High precision: Adopting a rigid chain transmission device ensures repeated positioning accuracy, which can reach millimeter level or even higher precision. In semiconductor cleanrooms, fully enclosed rigid chain elevators can transport wafer boxes in Class 10 dust-free environments with high positioning accuracy, meeting the needs of the precision manufacturing industry.
Fast speed: Each rigid chain can achieve a running speed of 200mm/s-600mm/s, and some high-speed models can reach speeds of 19m/min or even higher, greatly improving work efficiency.
Load bearing and travel advantages: The rigid chain lifting platform has the characteristics of large load capacity, high travel, and shallow foundation pit. The load range can range from 100kg-10t, covering all scenarios from light assembly to heavy equipment handling, and can meet the needs of different industries.
Energy saving and environmentally friendly: It does not use hydraulic or pneumatic transmission, making it more energy-efficient compared to hydraulic elevators. For example, Chunben's 1T model (including regeneration unit) saves 53% of electricity compared to hydraulic elevators.
Easy to maintain: compact structure, easy and fast installation, and low maintenance workload in the later stage. The key components such as chains have a long service life and are easy to replace, with annual maintenance costs only one-third of traditional equipment.
