HR-DT08 Duplex four-floor transparent simulation teaching elevator model

Equipment Overview

HR-DT08 Duplex four-floor transparent simulation teaching elevator model is based on the common elevator structure, made of transparent organic materials, its structure and the actual elevator is exactly the same, and almost has all the functions of the actual elevator. In order to facilitate the teaching, most of the parts of the elevator are made of transparent organic materials, making the internal structure of the elevator at a glance; at the same time, the elevator's operation process, as well as each action is very clear, and can be repeated hands-on operation. So that students can be very intuitive, thorough understanding, master the structure of the elevator and its action principle, to achieve twice the result with half the effort. Solve the previous elevator teaching purely theoretical teaching methods or visit the actual elevator brought about by the insecurity, can not fully understand its internal structure and operation process and other practical problems.

HR-DT08 Duplex four-floor transparent simulation teaching elevator model's electrical control system adopts Mitsubishi Programmable Controller (PLC) to realize logic intelligent control, Panasonic VF100 AC frequency conversion speed control drive, and its hardware structure composition and functions are exactly the same as those of the actual elevator. Its hardware composition and functions are exactly the same as those of the actual elevator. It has the functions of automatic leveling, automatic door opening and closing, responding to the call signals inside and outside the car in the right direction, driving straight, protecting the safe operation of the elevator, as well as the functions of the elevator stopping urgently, slowing up, slowing down, illumination, fan, and so on. And has a reliable performance, smooth operation, simple operation, low energy consumption and easy to teach and so on.

Basic functions of the device

1、Overspeed safety protection system

When an elevator accident occurs, the car slides down in overspeed or high speed (such as the wire rope breaks, the top pulley detaches, the worm gear of traction machine fails to work, and the motor rotates down too high). At this time, the speed limiter will be emergency braking, through the safety steel cable and linkage mechanism, drive the safety clamp action, so that the car stuck in the guide rail and will not fall.

2、Spring buffer device for car and counterweight

Buffer is the safety device at the limit position of the elevator. When the elevator fails and causes the car or the counterweight to squat or rush to the top (the limit switch protection fails), the car or the counterweight hits the spring buffer and the buffer absorbs the energy of the elevator, so as to decelerate the car or the counterweight to stop safely.

3、Door safety contact plate protection device

On the edge of the car door, there is a movable safety contact plate. When the door is closed and the safety contact plate comes into contact with passengers or obstacles, the linkage connected with the safety contact plate will touch the micro switch installed on the car door, so that the door can be opened again to avoid accidents.

4、Up and down limit switch:

In the elevator shaft of the upper and lower end of the installation of this switch, and installed in the upper and lower limit switch, the purpose is to protect the more box does not exceed the range, if beyond the upper limit or lower limit, the motor automatically stops, not in the work, with the upper and lower limit switch to distinguish between the switch will not fall off the power.

5、Lobby door automatic closing device

The opening and closing of the elevator floor door is realized by the door 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 engages, and only at this time can the elevator start running.

6、Floor door chain switch:

When the doors of all floors are closed, the elevator can be lifted and lowered. If the door of one floor is open, the elevator can not run.

7、Terminal limit switch safety protection system

There are terminal limit switches on the top and bottom floors of the elevator shaft. When the elevator is out of control due to a fault and the car goes to the top or squats at the bottom, the terminal limit switch will act, send out an alarm signal and cut off the control circuit, so that the car stops running.
