Double-Link Six-Storey Transparent Simulated Teaching Elevator Model 5168CSAS

I. Overview:
This transparent simulated teaching elevator is designed to facilitate experimental demonstrations in elevator and industrial automation courses at universities, technical schools, vocational schools, employment training centers, elevator maintenance and property management departments, and other institutions. This allows more people to better understand and use elevators, cultivate more elevator professionals, and meet the needs of the elevator industry. Our company has meticulously designed this model after in-depth research.
This elevator is based on the most common lift structure and is constructed of transparent organic materials. Its structure is identical to that of an actual elevator, and it possesses nearly all of its functions. To facilitate teaching, most components are constructed of transparent organic materials, making the internal structure clearly visible. Furthermore, the elevator’s operation and every movement are clearly visible, allowing for repeated hands-on practice. This allows students to intuitively and thoroughly understand and grasp the elevator’s structure and operating principles, achieving twice the result with half the effort. This model addresses the practical issues of previous elevator teaching methods, such as purely theoretical teaching methods or visits to actual elevators, which can lead to unsafe conditions and a lack of comprehensive understanding of the internal structure and operation.
The elevator’s electrical control system utilizes a Mitsubishi programmable logic controller (PLC) for intelligent logic control and a Panasonic VF100 AC variable-frequency drive. Its hardware components and functions are identical to those of an actual elevator. It features automatic leveling, automatic door opening and closing, forward response to elevator calls from inside and outside the car, direct travel, safe operation protection, emergency stop, slow ascent and descent, lighting, and a fan. It offers reliable performance, smooth operation, simple operation, low energy consumption, and ease of instruction. II. Basic Elevator Structure

III. Basic Functions of Elevator Mechanical Devices
A. Overspeed Safety Protection System
When an elevator accident occurs, the car may overspeed or descend at high speed (e.g., due to wire rope breakage, detachment of the car top pulley, malfunction of the traction machine worm gear, or excessive motor speed). At this point, the speed governor activates the emergency brake, driving the safety clamps through the safety cable and linkage mechanism, locking the car on the guide rails and preventing it from falling.
B. Spring Buffers for Car and Counterweight
The buffers are safety devices for elevator extreme positions. When an elevator malfunction causes the car or counterweight to bottom out or top out (limit switch protection fails), the car or counterweight impacts the spring buffers, which absorb the energy from the elevator, safely slowing the car or counterweight to a stop.
C. Door Safety Touch Plate Protection Device
A movable safety touch plate is installed on the edge of the car door. When the door is closing and the safety touch plate contacts a passenger or obstacle, a linkage connected to the safety touch plate triggers a microswitch on the car door, causing the door to reopen, preventing an accident. D. Upper and Lower Limit Switches:
These switches are installed at the upper and lower ends of the elevator shaft, within the upper and lower limit switches. Their purpose is to protect the elevator car from exceeding these limits. If the upper or lower limit is exceeded, the motor automatically stops and ceases operation. Unlike the upper and lower limit switches, these switches do not lose power.
E. Automatic Landing Door Closing Device:
The elevator landing doors are opened and closed by door blades installed on the car doors. Each landing door is equipped with a door lock. When the landing door is closed, the mechanical lock hook of the door lock engages, allowing the elevator to start.
F. Landing Door Interlock Switch:
When all landing doors are closed, the elevator can ascend or descend. If even one landing door is open, the elevator cannot operate.
G. Terminal Limit Switch Safety Protection System: Terminal limit switches are installed at the top and bottom floors of the elevator shaft. If the elevator loses control due to a malfunction and the car hits the top or bottom, the terminal limit switches activate, generating an alarm signal and disconnecting the control circuit, causing the car to stop.
