Occupant；Middle interlayer 30, carriage top panel 20, are provided with safety door, and safety door is usually closed, and can open when needed, carriage
Occupant can make carriage slowly nearby by the cat ladder upstream operation manual releasing band brake apparatus 19 being arranged on carriage side plate
Flat bed；Even if car slipping occurs for lifting device (such as lifting device is out of service, and just chance band-type brake failure can not brake) out of control, by
In winding star sending and receiving electric braking, very big torque will be produced under the rotating speed of very little, makes the speed of lifting device car slipping become
Very slowly, can be that rescue personnel rescues the strong help of offer in time.
Face gear train assembly, have the advantages that it is many, 1, pinion gear is when being involute cylindrical gear, the axis of pinion gear
Transmission performance is had little to no effect to displacement error；2nd, gear ratio common Bevel Gear Transmission registration in face significantly increases,
Up to 1.6~1.8, be conducive to improve the stationarity of transmission and increase bearing capacity；3rd, it is small when pinion gear is straight spur gear
Gear can simplify supporting, mitigate system weight from responsive to axial force；4th, when pinion gear is involute cylindrical gear, nibble at the same time
It is identical to close the common normal of tooth pair, is transmitted for power extremely advantageous；5th, for the gear drive of point contact face, can ensure in theory
Stable drive ratio is driven, and this point is for using a pair of of above drive gear and the symmetrical meshed gears teeth bar type up-down of drive rack
For equipment, it is very advantageous in and improves traveling comfort and reduction vibration and noise；Than common bevel gear transmission or
Either chain-wheel mechanism all weight is lighter is handed over plus electric drive system for permanent magnet direct current motor system or permanent magnetism for Worm gear mechanism
Synchronous motor system is flowed, it is compact-sized small, light-weight, and in addition cranking system need not be set, many-sided effect is folded
Add so that the significant effect of whole carriage mitigation dead weight, can significantly increase carrying capacity；Permanent magnet motor uses permanent magnetism material
Material, consumes so that motor power factor is improved, with conventional asynchronous phase without magnet exciting coil and exciting current
Than energy consumption is greatly lowered, and mitigates the significant effect of dead weight plus carriage, and many-sided effect is superimposed, and energy-saving effect is obvious；Forever
Magnetic-synchro motor transmits power using non-contacting electromagnetic force, realizes that compared with the slow-speed of revolution stable drive, have by electromagnetic method
Buffer shock-absorbing ability, noise are low, so overall noise and vibration may be significantly improvement；In permasyn morot operation,
When three-phase windings star connects, the kinetic energy and potential energy of carriage reversely drive motor can enter dynamic brake state, and produce foot
Enough big braking moments prevent car speeding, so it is avoided that carriage is rushed to summit or crouching bottom accident, when lifting device powers off suddenly,
The electromagnet dead electricity of brake, brake brake sticking brake immediately, ensure that safety；If lifting device position is not in flat bed at this time
Position, can use the manual releasing band brake apparatus on braking permanent magnet synchronous motor device, unclamp permasyn morot manually
The band brake apparatus of brake, makes carriage slowly flat bed nearby, saves occupant, (such as lifting device stops even if lifting device is out of control
Only run, but just meet band-type brake failure can not brake) occur car slipping when, due to winding star sending and receiving electric braking, under the rotating speed of very little
Very big torque will be produced, makes the speed of lifting device car slipping become very slowly, to allow carriage slowly flat bed nearby；
The electric interlock set in electric control system adds " power-off star connects " element circuit of mechanical interlocking, strengthens star sending and receiving electric braking
Security；Drive system is driven the driving force of lifting device carriage symmetrical, front and rear symmetrical, is ensured using symmetrical driving
Lifting device it is safe and reliable, it is stable；Therefore, the present invention can play and significantly improve operational efficiency and running quality,
Save material, save the energy, the beneficial effect of environmental protection.
