TECHNICAL SPECIFICATIONS
Presentation of the system:
- Operative Part:
- sheath made up of a metal structure of section 1080 mm х 930 mm х 3500
mm/3 levels
- cabin of dimension 700 mm х 750 mm х 700 mm and counterweight out of
sheath of 80kg approximately
- load variable cabin (cast iron weight) of 50kg with 100kg (for study of
precision of the stops)
- the rate of travel is approximately 0.5 m/s
- winch of asynchronous motor 2 speeds elevator (4 CV minis.) and brake
- limps of revision (or inspection cabin) and limps of recall
- landing button manufacture
- characterization of supplements out of anodic aluminum and transparent
polycarbonate
- access to the sheath by 3 large doors (H * l=3000 * 1000) made safe by
contacts of safety
- selector out of sheath made up of 5 roller sensors + cam
- panel equipped with the various connectors harting type for connection
on the operative part of the various sensors, electrical equipment boxes…)
Associated teaching activities:
• adjustment of the races of deceleration
• adjustment of the positions of revision
• adjustment of the race ends
• adjustment of the brake of the winch in drive of real load
• radial force cabin for taking into account in the adjustments
- Electric Box of power (RDU) integral:
- 1 disconnecting switch will tétra
- circuit breakers + differential
- Cupboard of operation integrating “Bi speed”:
- Contactors and charts of piloting (material of elevator)
- landing and gauge level button manufacture LCD
- standard fast connector harting for direct connection or on box with
variation of frequency (modernization)
- pocket of parameter setting of the cupboard
Associated teaching activities:
• Adjustment of the parameters of operation of the cupboard (a number of
levels, temporizations, distance between levels, desired mode of walk…
- Box of modernization integral “variator”:
- Chart of order (material of elevator)
- Variator of frequency (material of elevator)
- Standard fast connector harting for connection of the cupboard to the
remainder of the system
- In option: Variator Buckles closed + coder
Teaching -> activity:
• Modernization of the control device (integration of the variator box in
the loop of order of the machine/downstream from the two-speed cupboard)
• Adjustment of the parameters (acceleration, speeds fast, slow speed,
speed of revision, stages of deceleration…) on variator
- Position encoders:
- Optical position Encoder + rope + flags
- Magnetic sensors + loving
- Case of counting to band (incremental coder) + magnetic tape
Associated teaching activities:
• Positioning and adjustment of the position encoders to flags (optical
sensor)
• Positioning and adjustment of the magnets (magnetic sensors)
• Parameter setting of the case of control on incremental coder |
|
PEDAGOGIC APPLICATIONS
• Study of the dynamic and static behaviour of an elevator
• Description of the influence of technologies on the precise
details of stop and the comfort of use
• Behaviour of an installation with variable load
• Adjustment influence of brake on the precision of stop
• Adjustment of the zones of deceleration and the positions of
stop according to technologies of sensors and technologies of
cupboards.
• Adjustment of a system with 2 speeds order.
• Adjustment/parameter setting of a system with order by
variator
