Abstract

Provided is an elevator without a counterweight and with double cages. A cage is hung at each end of a steel wire rope hung on a traction sheave, the two cages are balance bodies mutually, a counterweight does not exist, and the two cages carry out vertical movement simultaneously in a lift shaft under dragging of the friction between the traction sheave and the steel wire rope. The elevator without the counterweight and with double cages is suitable for residential building and the central service area of blocks with consistent building story heights.

Description

The counterweightless double-car elevator
Technical field
The present invention relates to the traction vertical lift elevator, especially the counterweightless double-car elevator
Background technology
At present, in skyscraper, require the elevator traffic capacity very high, by several even tens form elevator group and come passenger-carrying, the elevator of portable and effective and reduce elevator hoistways to take building area particularly important, existing elevator be steel wire hang on traction sheave, steel rope two ends are being suspended respectively car and counterweight in midair, car rises under friction force between traction sheave and steel rope drives, and counterweight descends; Or cage descending, counterweight rises, and the weight of counterweight is car weight and about 50% elevator nominal payload sum but only play effect with the car balance, and occupies 1/4 left and right of elevator hoistways area.
Summary of the invention
Reduce in order to reduce building cost the area that elevator hoistways takies, alleviate the weight of lift facility, improve the carrying capacity of elevator, the invention provides a kind of counterweightless double-car elevator, this elevator is counterweightless not only, and transporting power is equivalent to the traffic capacity of two existing elevators.
the present invention solves technical scheme that its technical matters adopts: steel wire hang is on traction sheave, a car is respectively being suspended at the steel rope two ends in midair, two cars are balanced body each other, counterweightless, two cars are under friction force traction between traction sheave and steel rope, on doing simultaneously in hoistway, lower perpendicular movement, the contact arc length that press rope wheel increases steel rope and traction sheave has satisfied the traction condition, track adjusting wheel is used for determining the position of steel rope in car hoistway, every layer of Room peripheral hardware cage operation bearing meter and destination logger, apparatus for controlling elevator adopts the set of two car collection choosings.
The invention has the beneficial effects as follows: counterweightless double-car elevator quite with in the transporting power of two existing elevators, and saved counterweight and building area thereof, again can efficient energy-saving ground move, kill two birds with one stone.
Description of drawings
Fig. 1 is the site plan of traction sheave of the present invention, press rope wheel and track adjusting wheel.
Fig. 2 is press rope wheel axle bed inserted sheet.
1. traction sheaves in figure, 2. steel rope, 3. press rope wheel, 4. press rope wheel axle bed inserted sheet, 5. track adjusting wheel, 6. load-bearing girder steel, 7. car, 8. hoistway.
The specific embodiment
Take command speed as 2m/s, nominal payload is 1000kg below in conjunction with accompanying drawing, and the car deadweight is that the present invention is further described for example for the counterweightless double-car elevator of 1550kg.
in Fig. 1 with traction sheave Central Symmetry distribute two press rope wheels and track adjusting wheel, press rope wheel, track adjusting wheel be installed on the load-bearing girder steel and with traction sheave with in one plane, press rope wheel makes the corresponding cornerite of steel rope contact arc length on traction sheave satisfy the traction condition greater than 270 °, during the elevator operation, two cars are done simultaneously, lower perpendicular movement, both up cars, when which floor rising descending car descending which floor, in order to guarantee the accurate level of two cars, the counterweightless double-car elevator requires the building floor height consistent, and the accurate Calculation rope capacity makes two cars be parked in floor when central authorities, reach the flat bed standard, press rope wheel axle bed inserted sheet is used for adjusting steel rope and cornerite thereof.Control system adopts the set of two car collection choosings, and every layer of Room peripheral hardware cage operation bearing meter and destination logger satisfy passenger's demand like this with energy-efficient operational mode.

Claims (2)

1. counterweightless double-car elevator, steel wire hang is on traction sheave, it is characterized in that: a car is respectively being suspended at steel rope two ends in midair, two cars are balanced body each other, counterweightless, described two cars are made upper and lower perpendicular movement simultaneously in hoistway under the traction of friction force between traction sheave and steel rope.
2. counterweightless double-car elevator according to claim 1 is characterized in that: steel rope is between traction sheave and press rope wheel, and the contact arc length that press rope wheel increases steel rope and traction sheave has satisfied the traction condition.
