Abstract

The invention provides a cable-free elevator. An electric motor, a battery, a wireless sensing power receiving coil are arranged in an elevator lift car, and a rail and a radio frequency charging coil are arranged on a lift car operation passage, so the elevator breaks the tether of steel ropes, and the cable-free elevator operates on the rail by the self motive power. The cable-free elevator has the advantages that the functions of multi-life-car simultaneous passing, horizontal moving, unidirectional moving and the like can be realized, the passenger carrying efficiency of the elevator is improved, the energy consumption is reduced, and accidents are reduced.

Description

Without cable elevator

Technical field

In building, be widely used the passenger-goods lift of power delivery, be mainly the wirerope vertical lift, bel-drivenn rotating ladder, the hydraulic lifting elevator that drag car, have cable to tow power lift car elevator etc., belong to technical innovation without cable elevator, do not retrieve identical or close technology and realize and apply.

Background technology

Elevator is widely used in modern architecture, in skyscraper, the main tool of people or goods delivery is elevator, the elevator of perpendicular movement mainly comprises electrical motor and drive part, signal control part, car door and car, wirerope and counterweight etc. at present, owing to there being wirerope constraint, electrical motor only draws a car, can only have a car in operation in whole like this elevator hoistways, and vertically one-way movement, the carrying capacity of elevator is restricted, and traffic efficiency declines; For avoiding elevator to block up, most of building is used multi-section elevator, takies a large amount of spaces; Because car is pind down by wirerope, often there is the problems such as wirerope skids, wearing and tearing, cause dangerous situation and increase accident; Due to the power driven of needs power supply, prior art elevator electric power fault or the emergency state cannot be used, can not emergency evacuation, for these problems, adopt current up-to-date technology to redesign elevator, can finely overcome the above problems, use wireless charging technology, allows lift car break away from cable and wirerope becomes possibility.

Summary of the invention

Be made up of track and car without cable elevator, orbit distribution is in transit passage, and car power wheel orbits, and radio frequency charge coil is installed near elevator parking station, is the charging of stoppage type elevator battery, wireless induction is set in car and is subject to electric coil, battery pack, electrical motor, gear unit, control unit, communication system etc., by radio-frequency electromagnetic radiation, bus stop radio frequency charge coil is that in car, wireless induction is subject to electric coil to carry alternate electromagnetic radiation, wireless induction is subject to electric coil to induce electric current to batteries charging, battery pack drags gear unit by control unit drive motor, car is moved, car just can rely on power to turn round in orbit like this, while relying on gravity descending, conventional elements dragging motor, slow down and generate electricity with electrical motor reluctance force, for batteries charging, can save like this electric energy.

The specific embodiment

Utilize without cable elevator technology, can manufacture building inner circulation structure passenger-goods lift, realization is up or descending continuously continuously, also can manufacture helical structure elevator or incline structure elevator.Can also realize and improve traffic efficiency, energy-saving and cost-reducing by transformation traditional elevator.

Make people's freedom of motion in building without cable elevator, current convenient, in building or between groups of building, can freely connect charging elevator rail, change the operational mode of traditional elevator, can opposing traffic, laterally current, circulation is current, elevator traffic efficiency improves like this, owing to changing carriage lift amount has been increased without the current mode of cable elevator, four times of the carrying capacities of traditional elevator, space hold amount is 25% of traditional elevator, save space more than 75%, due to the employing design that has free passage, can rely on gravity descending, in descending process, not only do not need power, slow down and generate electricity with electrical motor reluctance force, can save a lot of power consumption, use battery energy storage, under power failure and the emergency state, car can be continued a journey, emergency evacuation or escape can be used charging elevator, multi-section car can turn round on charging elevator rail simultaneously, it can be so just each user personality customization different stage car, even each user can have the car of oneself, meet people's individual demand, change architectural design scheme, promote safer, more environmental protection, more healthy building is born, when improving traffic efficiency, realize energy-saving and cost-reducing.

Claims

1. without a cable elevator, electrical motor, battery, wireless induction are installed in lift car and are subject to electric coil; Attachment rail, radio frequency charge coil on car running passage, make elevator break away from wirerope constraint, rely on that self power turns round in orbit without cable elevator, can realize the functions such as the serial of many cars, parallel motion, one-way movement, improve elevator carrying efficiency, reduce energy consumption, minimizing accident.
