Abstract
The invention discloses an energy-saving elevator without a traction motor. In the energy-saving elevator, a car traction wheel is linked with a counterweight block traction wheel through a stepless transmission; the relative speed is adjustable; the elevating power of a car is realized by changing the relative torque difference between the car traction wheel and the counterweight block traction wheel through the stepless transmission; the weight of the counterweight block is constant; the weight of the car changes between idle load and full load; after the weight of the car is determined and the car is elevated or lowered, the transmission can be adjusted through a sensor and a controller in order to change the relative torque between the car traction wheel and the counterweight block traction wheel; if the torque of the car traction wheel is smaller than the torque of the counterweight block traction wheel, the car ascends; if the torque of the car traction wheel is greater than the torque of the counterweight block traction wheel, the car descends, so that the aims of eliminating the traction motor and saving energy are fulfilled.

Background technology
Skyscraper is the most effective means of Economization on land, and therefore, in the city that soil is rare, high building stands in great numbers invariably, has high building must have elevator, otherwise people are upper just very painstaking downstairs.In adding up the electricity consumption condition survey of hotel, office building etc., elevator power consumption accounts for more than the 17%-25% of total electricity consumption, is only second to idle call electricity, and higher than the power consumption of illumination, water supply etc., current elevator has become one of civilian current consuming apparatus rich and influential family of China.Therefore, research and develop, promote the use of Novel energy-saving elevator, there is positive effect.Current elevator energy-saving adopts mature various technology to have nobody automatically turn off the light technology, actuator dormant technology, escalator variable frequency induction start-up technique, team control building intelligent management technique etc. of car all can reach good energy-saving effect.Chinese patent " energy-saving lift with adjustable counterweight power " application number 200610124012.0, notification number 1974361, change traditional traction motor retarder into variable speed type retarder, certain improvement result is played to the applying working condition of traction motor, but many weeks, laborsaving not saving of labor, saving of labor is not laborsaving, its energy-saving effect is limited, adopts variable frequency dragging motor effect more much better than it.For the traction-type bridge case elevator that current use amount is maximum, traction motor is must obligato power resources, is also consuming components maximum in elevator device.
Summary of the invention
Object of the present invention: the object of the invention is to utilize the deadweight of bridge case, clump weight deadweight and principle of moments, cancel consuming components traction motor maximum in traction-type bridge case elevator device, reach the object of elevator energy-saving.Principle of the present invention is popular is exactly that bar claims principle: pan of a steelyard is equivalent to bridge case, sliding weight of steelyard is equivalent to clump weight, and buncher is equivalent to rope, even if the scale pan and sliding weight of steelyard vary in weight, if but change the position of rope, just can make the scale pan or rising or drop or balance.
The present invention is achieved in that
Without an energy-conserving elevator for traction motor, comprise bridge case traction sheave, buncher, clump weight traction sheave, bridge case rope, clump weight rope, bridge case, clump weight; It is characterized in that: bridge case traction sheave connects clump weight traction sheave by buncher, bridge case rope one ends wound on bridge case traction sheave, the other end is connected with bridge case, clump weight rope one ends wound on clump weight traction sheave, the other end is connected with clump weight.
Described a kind of energy-conserving elevator without traction motor, is characterized in that: the relative rotation speed of bridge case traction sheave and clump weight traction sheave, regulates by buncher.
Described a kind of energy-conserving elevator without traction motor, is characterized in that: buncher, to the adjustment of bridge case traction sheave and clump weight traction sheave relative rotation speed, is regulated by controller automatically according to sensor signal and operating switch instruction.
Advantage of the present invention:
The present invention utilizes the deadweight of bridge case, clump weight deadweight and principle of moments, cancels consuming components traction motor maximum in traction-type bridge case elevator device, reaches the object of elevator energy-saving.
