Release time：2024-06-27 01:00viewed：times

In order to cooperate with the demonstration experiments of elevator and industrial automation courses in colleges, technical schools, vocational schools, labor employment tr*ning centers, elevator m*ntenance and property management departments, so that more people can better understand and use elevators, cultivate more elevator professionals, and adapt to the development needs of the elevator industry, our company has carefully designed the LYT series of transparent simulation teaching elevators after in-depth exploration and research.
Zhongren's LYT series of transparent elevators are made of transparent organic materials based on the most common lifting elevator structure. Its structure is exactly the same as that of an actual elevator, and it has almost all the functions of an actual elevator. In fact, it can be regarded as a miniaturized real elevator.
In order to facilitate teaching, most of the parts of the elevator are made of transparent organic materials, so that the internal structure of the elevator is clear at a glance; at the same time, the operation process of the elevator and each action are very clear, and can be repeatedly operated. It enables students to intuitively and thoroughly understand and master the structure and operation principle of the elevator, achieving twice the result with half the effort. It solves the practical problems such as the unsafe teaching method of pure theory in previous elevator teaching or the inability to fully understand its internal structure and operation process when visiting the actual elevator. The electrical
control system of the elevator adopts Mitsubishi's programmable controller ( PLC ) intelligent control and AC variable frequency speed drive. The composition and function of its hardware structure are exactly the same as those of the actual elevator. It has automatic leveling, automatic door closing, forward response to elevator call signals inside and outside the car, direct driving, elevator safety operation protection, elevator emergency stop, slow up, slow down, lighting, fan and other functions. It has the characteristics of reliable performance, stable operation, simple operation, low energy consumption and convenient teaching. In addition, the software and hardware of the transparent simulation teaching elevator adopt an open structure, so colleges and universities can also use this set of devices for secondary development and research. Such as: group control elevator (unified dispatch of multiple concentrated parallel elevators); parallel control elevator (control lines of 2-3 elevators are connected in parallel for logical control and share the call button outside the floor station); collective selection control elevator; signal control elevator, etc. The inverter is used as the speed control device of the three-phase AC traction prime mover. The device adopts voltage vector control mode, and has multiple functions such as acceleration and deceleration control, forward and reverse control, inching control and control according to analog input. At the same time, it also has protection functions for the prime mover's phase f*lure, phase loss, phase sequence disorder, overvoltage, undervoltage, overcurrent, overload, stall, etc. The use of this set of equipment for supporting teaching enables teachers and students to have an intuitive and vivid understanding of the structure, key components, electrical control, and operation process of the elevator, and it is easy to deepen the understanding and mastery of elevator-related knowledge. In addition, by using FPWINGR software, ladder diagram programming can be directly performed on the PC, and actual operation and debugging can be performed on site, which is of great help to students in learning, understanding and mastering programmable controllers (PLCs) and their applications as well as industrial process automation control. The logic control of the elevator system is completed by PLC (can be connected online). The PLC uses the FX3U-64MR model of Mitsubishi Corporation of Japan, and its output mode is relay output. The communication between PLC and PC can be realized through the RS422 or RS232 interface equipped on the host. Using GX-Developer software, ladder diagram programming and debugging can be directly performed on the PC, which is intuitive and easy to learn, and easy for beginners to master; in addition, FP programmer II can be used for instruction programming and direct debugging on site. Transparent simulation teaching elevator complete set of equipment: 1. M*n elevator model - including Mitsubishi FR-D720S-0.4 inverter, Mitsubishi FX3U-64MR programmable controller (PLC); 2. PLC peripheral dedicated communication cable; 3. Mitsubishi programmer operation manual; 4. Mitsubishi PLC dedicated programming tool software; 5. Teaching elevator instruction manual. Basic structure of elevator: 1. Machine room part: including traction reducer, traction motor, brake, traction wheel, speed limiter, rotary encoder. 2. Hoistway part: including guide r*ls, counterweight mechanism , car (door machine mechanism, safety clamp, guide shoe, lighting, fan), floor door, floor call indicator controller, traction rope, guide wheel, first floor leveling sensor (counting reset), upper (lower) limit switch, upper (lower) limit switch, accompanying cable, car controller, buffer, etc. 3. Electrical control part: power *r switch (leakage release), DC12V drive power supply, PLC programmable controller, wiring port circuit board, arrival clock, etc. The elevator car position detection and electrical floor selection signal are obt*ned by the bistable magnetic switch installed on the top of the car and each floor station, thus getting rid of the complicated line system controlled by contact devices such as relays and contact switches in the past, optimizing the line, greatly improving the reliability of system operation, and facilitating m*ntenance. A. Speed limiter and safety clamp protection system When an accident occurs, the car overspeeds or slides down at high speed (such as wire rope breaking, car top pulley detachment, traction machine worm gear meshing f*lure, motor descending speed too high, etc.). At this time, the speed limiter will brake urgently, and drive the safety clamp to act through the safety steel cable and connecting rod mechanism, so that the car is stuck on the guide r*l and will not fall. B. Spring buffer device for car and counterweight The buffer is a safety device at the extreme position of the elevator. When the elevator f*ls and causes the car or counterweight to hit the bottom or top (the limit switch protection f*ls), the car or counterweight hits the spring buffer, and the buffer absorbs the energy of the elevator, so that the car or counterweight can be safely decelerated until it stops. C. Terminal limit switch safety protection system Terminal limit switches are installed on the top and bottom floors of the elevator shaft. When the elevator loses control due to a f*lure and the car hits the top or bottom, the terminal limit switch cuts off the control circuit and stops the car. D. 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, the micro switch installed on the car door is touched through the connecting rod connected to the safety touch plate, causing the door to reopen and avoid accidents. E. Door machine torque safety protection device
The door machine uses a cert*n torque to close the car door and the hall door at the same time. When an object or a person is caught in the door, the closing torque is increased, so the car door and the hall door are automatically reopened through the connected travel switch, thereby avoiding accidents.
F. Automatic closing device for hall doors
The opening and closing of the elevator floor door is achieved by the door opening blade installed on the car door. Each floor door is equipped with a door lock. After the floor door is closed, the mechanical lock hook of the door lock is engaged, and the electrical interlocking contacts of the floor door and the car door are closed, and the elevator control circuit is connected. Only then can the elevator start running.
