1. Definition and Principle
The rigid chain lifting platform is a mechanical device that achieves vertical lifting through rigid chain transmission. Its core is the rigid chain transmission mechanism, which consists of a series of high-strength metal chain links. The motor drives the chain to rotate and mesh to form a rigid support column, which drives the platform to rise and fall smoothly.
Working Principle:
The motor drives the rigid chain to rotate, and the chain links form a rigid column through precise meshing.
The chain stretches or contracts in the guide device, driving the platform up or down.
Similar to "screw transmission", but the rigid characteristics of the chain make it less likely to bend under high loads and more stable.
2. Core Components
Drive unit: The motor (servo/stepper) provides power, and the reducer controls speed and torque.
Rigid chain: High-strength alloy chain links with self-locking function to ensure safe load-bearing.
Guide mechanism: Accurately guide the chain movement to prevent deviation.
Control module: PLC or microcontroller achieves precise positioning and supports automated operation.
Safety devices: overload protection, emergency brake, anti-fall lock, etc. to ensure safe operation.
3. Features and advantages
High load capacity: The rigid chain structure can carry several tons to tens of tons (such as 10-30 tons for stage equipment).
Compact design: Small footprint, suitable for narrow environments (such as underground garages or factory workshops).
Smooth operation: Low noise (usually <60 dB), no hydraulic fluctuations, suitable for precision operations.
Easy maintenance: No risk of hydraulic oil leakage, long chain life (usually 5-10 years without replacement).
Precise positioning: Repeated positioning accuracy can reach ±0.1mm, suitable for high-precision scenarios such as semiconductor manufacturing.
4. Typical application scenarios
Stage and theater: lifting stage, lighting rack (such as Broadway theater can lift multiple platforms simultaneously).
Industrial automation: Production line material transfer, automobile assembly line (such as battery pack lifting in Tesla factory).
Logistics warehousing: High-density shelf storage and retrieval (cooperating with AGV to achieve fully automated warehousing).
Special fields: aircraft maintenance platform (bearing fuselage weight), medical operating table (stepless precision adjustment).
Intelligent parking: vertical lifting stereo garage (saving space and increasing capacity).
5. Selection considerations
Load requirements: select chain specifications (such as single chain/double chain structure) according to actual load.
Lifting height: The chain length determines the stroke, and a safety margin needs to be reserved.
Environmental adaptation: dust-proof and explosion-proof design (such as stainless steel materials are required in chemical workshops).
Control integration: whether to connect to the Internet of Things system (such as remote monitoring or automatic scheduling).
6. Future development trends
Intelligence: Combined with AI predictive maintenance, real-time monitoring of chain wear status.
Lightweight: Use carbon fiber composite materials to increase strength and reduce weight.
Modular design: Quick disassembly and assembly to meet flexible production needs.
