WQ-DT2001 passenger and freight elevators simulation teaching a dual transparent, transparent overview of passenger and cargo lift is in line with the simulation teaching colleges, technical schools, vocational schools, employment training centers, Special Equipment Inspection Center elevator operator training posts Experimental demonstration of professional teaching equipment related to elevators and industrial automation professional curriculum development permits, elevator maintenance and property management. Its appearance imported transparent plexiglass material, so that students will better understand the use of the elevator, the structural principle, the principle of operation, control, train more professionals in the elevator, the elevator and automation to adapt to the professional development needs, and I The company after several site visits, elevator manufacturers and elevator simulation experts to develop a teaching model for passenger (TKJ) freight elevators (THJ) which Keti 1: 1 Traction, open the door to carve Lifts 2 : 1 Traction, left open the door for the bi-fold door, allows students a good understanding and visually see each run health institutions. Elevator electrical control system adopts imported programmable controller (PLC Mitsubishi) intelligent control and frequency (VVVF Yaskawa) speed regulator FM drive, which parts of the structure, working principle functions exactly the same as the actual elevator and safe Clamp the governor overspeed protection system security. 1, the elevator using industrial aluminum frame structure, the base of the elevator hoistway integrated design, construction beautiful, durable; 2, the base is made of 1.2mm cold rolled steel refining, and shot peening, including special production base casters for easy movement of the elevator; 3, the important parts of the elevator are imported transparent plexiglass made fine, complete simulation of real lift all the features; 4, including voice-stop elevator function, can accurately report the elevator where the station level , the upper and lower bit overweight and other information 5, elevator lift by independent electrical control system to control the electrical cabinet configuration; two, the basic structure of the elevator machine room Part 1: Includes traction machine, brakes, speed limiter, traction sheave, guide wheel or rewind wheel, manual dish wheels, control cabinets, power switch, car light switch, wells and light switches. 2. Road into sections: the car, the car rails, heavy rails, heavy frames, bumpers, limit switches, limit switches, control cables, bearing line cable, the governor rope tensioner 3. car Part I: the car, safety gear, guide shoes, auto door machine, leveling devices, control boxes, command buttons inside the car, refers to a layer lights, car lighting, car maintenance inside the box and the car door combination. 4. Layer door parts: the hall door, call button box, floor displays, mechanical door locks, electrical interlocks. 5. The control section independent distribution cabinet distribution cabinet specifications: 800 × 450 × 1500 (mm) which contains the total power, control power supply, PLC programmable logic controller, inverter, wiring boards and other equipment Third, the basic function of the elevator A. When the overspeed protection system security elevator accident when the car speeding or speed the decline (eg broken wire rope, pulley off the car roof, traction machine worm combined failure, decreased motor speed is too high, etc.). At this time, the governor will be the emergency brake cable and linkage mechanism through security, driving safety gear, the car stuck in the rails without falling. B. car for reuse buffer spring buffer device is elevator safety device limit position, when the elevator breaks down, causing the car or at the bottom or hoisting heavy squats (limit switch failure protection), car or counterweight impact spring buffer, absorbing energy from the elevator buffer, so that the car or counterweight safety decelerate to a stop. C., the lower limit switch: In the elevator shaft, the lower end of the installation of the switch, and installed in the upper and lower limit switches, the play is intended to protect the more box does not exceed this range, if you exceed the upper limit or lower limit, the motor automatically stops, does not work, keep up the limit switches in this switch does not distinguish powered down. D. elevator hoistway door automatic closing device opening and closing of the door, is mounted on the car door by the door blade to achieve. Each floor is equipped with a door lock. After landing door is closed, the door of a mechanical latch hook engages, then lift to start running. E. landing door interlock switch: When the door all the layers are closed, the elevator can lift, if one layer door was open, the elevator that can not run. F. terminal limit switch security system at the top and bottom of the elevator shaft with a terminal limit switch. When the elevator is out of control due to a fault, rather than taking the car or squat bottom occurs, the terminal limit switch operation, an alarm signal and cut off the control circuit, the car stopped running. Fourth, the main technical parameters 1. Input voltage: AC 380 ± 7% 50HZ 2. Dimensions: Width 1070mm × 1550mm × height 2360mm 3. Deep landing form: Keti (four four four stations), freight (four Layer four station four). 4. Control: programmable logic controller (PLC) speed regulator FM (VVVF) assembly election. 5. Structure: four stations 6. Programmable Logic Controller (PLC): Model: Mitsubishi FXzn-64MR Input voltage: AC 220V 50HZ input and output points: 64 points (32 in, 32) Output: relay output 7. inverter: Model: TE380 3007 Input voltage: AC 220V 60HZ Rated current: 2.5A Power: 1.2KW 8. hoisting machine: Ratio: 30: 1 Modulus: 1.5 (worm gear reducer) 9. Drag motor : Model: JW5622 Voltage: AC 220V 50HZ Power: 180W speed: 2800r / min V.
