Traditional elevator frequency conversion (containing harmonic wave) drives towing machine and variable-frequency speed-regulating controller motion thereof, and frequency converter has high order harmonic, can make that the motor feels hot, and also can disturb electrical network at certain area, cost is high, and circuit is complicated, easy break-down.

And traditional elevator also has following problem:

1. traditional towing machine friction force easily changes, and causes traction to diminish, and out of control so that skidding accident occurs.

2. traditional elevator speed governing frequency modulation control device, its principle is 50HZ AC-DC, after become variable ratio frequency changer alternating current again, have an effect little, there is bad high order harmonic, make that the motor feels hot, output drop, and high order harmonic can disturb electrical network within the specific limits, the undercapacity when low speed ripple.

3. conventional security mechanisms: the mechanical linkage adopting physics centnifugal force, complicated, easily lack of proper care.

4. traditional elevator is huge, and installation, maintenance is inconvenient, and cost is high.

5. traditional elevator car, counterweight, track oil lubrication, have pollution, and its oil dripping mechanism also often may lose efficacy.

Gulang Island laser layer control elevator solves above-mentioned technical matters, adopts integrally car, composite material derrick three-piece to be combined into an elevator.This elevator structure normalisation, easy easy dress, safe and reliable, enter Building market in China, owing to being five nothings: inorganic oil, noiselessness, machine room, without rack, without tunnel, be especially suitable for Modern Family, have prospect widely, elevator is not dream, and every household is all enjoyed.

Detailed description of the invention

Embodiment 1

As shown in Figure 1, the utility model car operation schematic diagram, adopts towed pulling force to drive car and balanced body and safety gear photoelectricity machine.Wherein 1 integrated car, 2 is steel cable, and 3 is track adjusting wheel, and 4 is balanced body, and 5 is synchronizing wheel, and 6 is Timing Belt, and 7 is servo deceleration machine, and 8 is control system.Integration car is connected by steel cable with balanced body, centre is provided with track adjusting wheel, the up-and-down movement of integration car rotates and reverse the motion driving synchronizing wheel and Timing Belt, then integrated car 1 up-and-down movement, the 4 times upper motions of relative balanced body by servo.

As shown in Figure 3, section bar derrick belongs to composite material by pultrusion aluminum alloy and becomes gauge member section bar, is fixed into derrick by screw, corner brace.Establish two pairs of tracks in derrick, a pair guide track is optical axis 9, and leading boots is copper-base graphite composite materials, performance self-lubricating, does not need to refuel and device; Another is to being tooth bar safety tongs track 10, and for the safety tongs of the car balanced body 4 of relative motion, once hypervelocity, safety tongs engages with it, checks car 1 and balanced body 4.

Integrated car comprises envelope and control system as shown in Figure 2,3.Control setup is arranged in casing.Described control system comprises Serve Motor Control actuator 7, safety tongs, linear dc motion actuator 14,18, laser 15 (find range, test the speed), buffering blanket net 11 etc., because buffering blanket net is made up of 400 springs, therefore the buffering blanket of 2.5 centimetres high instead of single 0.5-2.5 meters high energy dispersers in traditional tunnel.So integrated car is without the need to tunnel.

The utility model laser layer control device as shown in Figure 4, layer control laser 15 is arranged on car, real-time testing height H 1 and time T, and with passenger call out (button inputs) number of plies height H 2 compared with, as H1>H2, cage descending (reversion of servomotor follow procedure), as H1< H2, car rises (rotating forward of servomotor follow procedure), as H1=H2, car is by layer (servomotor stopping), reach the object of layer control, laser velocimeter, when the speed car of measuring runs survey H1 up and down, microcomputer timing T, V=H1/T, (1) V1 microcomputer when command speed 20% exports and controls servomotor PWM(Pulse Width Modulation Control With device) proper motion, when V1 >=20% command speed, microcomputer sends instruction, make servomotor power-off, and the tooth bar that the linear dc motion actuator power supply starting safety tongs promotes safety tongs engages with rack rails, prevent car speeding hit top or disconnected rope fall, car is made to stop on rack-track, thus precisely select layer to lean on layer.Overcome traditional traction elevator and " by nearly switch ", " dry-reed tube " and so on device is installed layer by layer, install loaded down with trivial details.

Door machine as shown in Figure 5: adopt linear DC motor to promote car door and layer door, cancel traditional traction elevator governor and belt transmission mechanism, elevator door by linear dc motion actuator pushrod movement, when car reaches layer, microcomputer exports positive voltage, and DC machine is pushed the door open; When microcomputer exports negative voltage, DC machine pushes away closes door.
