1. Equipment overview

The transparent escalator tr--ning equipment is suitable for vocational colleges and secondary vocational colleges. The simulation escalator model adopts the transparent escalator step pedal system, handr--l belt system, traction machine system, device stand, safety detection system, electrical control control system, etc. Through the escalator teaching model, students can familiarize the working principles, structure composition, and low -voltage control electrical structures of the common escalator. Students can master the safety protection and working status of the elevator by analyzing the electrical schematic diagram. Point where the point is located, master the operating principle of the elevator and d--ly m--ntenance knowledge.

2. Technical parameters

2. The working environment: the environmental temperature range is -5 ℃ ～+40 ℃, and the relative humidity is <85%(25 ℃);

3. The capacity of the whole machine: ≤1.5kva

4. Architecture size: 3400mm (long) × 850mm (width) × 1800mm (height)

5. Improve height: 700mm

6. Control method: PLC or microcomputer control+frequency conversion start.

9. Safety protection: It has the function of protecting ground, overload, overcurrent, leakage current, and safely meets national standards.

3. M--n components

1. The escalator is composed of truss, driving reducer, driving device, tension device, guide r--l system, steps, step ch--ns, handr--l armrests and various safety devices.

(1) Torch: It is the infrastructure of the escalator. All parts of the escalator are assembled in the truss of this metal structure. It is welded with corner steel and type steel. The truss consists of 3 parts, namely the upper platform, the middle truss and the lower platform. In order to ensure that the escalator is in a good working state, the truss's rigidity is high. At the same time, the escalator truss has an intermediate branch to support the support, and it can be adjusted with the swelling and shrinking of the truss.

(2) Driver (take ch--n type as an example): The driver is m--nly composed of motor, worm worm sn--l reducer, sprocket, brake (sliding gate), etc. The installation position of the motor is a vertical drive. Its advantages are: compact structure, small land, light weight, easy m--ntenance; low noise and small vibration.
