Description

Multi-level elevator system experimentation actual training device

Technical field

The utility model relates to a kind of instruments used for education, especially, relate to a kind of multi-level elevator object teaching system experimentation actual training device that is widely used in courses such as universities and colleges' " electromechanical integration technology ", " PLC technique ", " modem elevator control technology ", " Mechanical ﹠ Electrical Transmission and control ".

Background technology

Multi-level elevator is a kind of elevator device that generally adopts in the modern architecture, and its typical structure is made up of car, hoistway, body of wall, counterweight, choosing layer mechanism, sound broadcast clock, controller, frequency converter, traction machine etc.The multi-level elevator system architecture of practical application is huge, distribute extensively, visual pattern not, be not suitable for directly as experiment device for teaching, for satisfying scientific research and teaching requirement, many multi-level elevator experimental facilitiess have also appearred in the market, but performance is uneven mostly, lacks comprehensive, the integration of system.The multi-level elevator system of some manufacturer production adopts analog control circuit, on and off by various pilot lamp come the putting in place of the operation of indication motor and car, toggle switch simulation floor to put in place, so not only troublesome poeration but also not visual in image is unfavorable for the teaching use.The notion of system has been ignored by this system of too simplifying, and is a kind of simple analog control experimental provision, has lost the meaning of elevator control.

The beneficial effects of the utility model are: the utility model is with respect to prior art, has that system architecture is complete, advanced technology, visual pattern and wide characteristics of covering universities and colleges specialty.

Embodiment

The utility model provides a kind of experimental real-training apparatus of simulating the multi-level elevator system fully, form simulation elevator running structure by base, car, hoistway, body of wall, counterweight, sound broadcast clock, Internal call button, external call button, floor indicator, frequency converter, traction machine and control system (manually control, control automatically).

Manual and the automatic two kinds of control modes of control system employing, under the self-actuated controller invalid state, manual control system can guarantee the reliability service of system, before system's input is moved automatically, the operating mode of manual control test power line and power-equipment.

Describe the specific embodiment of the utility model multi-level elevator system experimentation actual training device with reference to the accompanying drawings in detail.

As shown in Figure 1.Fig. 1 is the front elevation of the utility model multi-level elevator system experimentation actual training device, and this multi-level elevator system experimentation actual training device comprises base 9, be installed in the mobile pulley 10 under the base, be installed in hoistway 14 and body of wall 17 on the base, be installed in counterweight 23 and car 24 in the hoistway 14, be installed in the top cover 1 on hoistway 14 and body of wall 17 tops, be installed in traction machine 19 and rotary encoder 20 in the top cover 1, be installed in the external call button 16 at body of wall middle part, floor indicator 3, be installed in the frequency converter 2 of body of wall upper right quarter, be installed in the Internal call button 5 on body of wall right side, floor indicator 3 and sound broadcast clock 4, be installed in body of wall right lower quadrant Programmable Logic Controller 6 and controller power source switch 7, be installed in the service chamber 8 of body of wall right lower quadrant.

As shown in Figure 2.Fig. 2 is the left view of the utility model multi-level elevator system experimentation actual training device, and traction machine 19 links by shaft coupling and rotary encoder 20, and traction rope 21 is walked around counterweight 23, fixed pulley 18, rotary encoder 20, car 24 successively.Traction machine 20 drives car 24 and counterweight 23 vertical reverse direction operations by 20 rotations of driven rotary scrambler.
