Abstract

The invention discloses a novel double-counterweight elevator. The novel double-counterweight elevator comprises a vertically-arranged hoistway, a car moving up and down in the hoistway, a counterweight device, a driving device and a control device, wherein the driving device comprises a first driving device and a second driving device; the first driving device comprises a first steel wire rope, and a first motor, a first speed reduction box and a first dragging wheel which are in driving connection with one another in sequence; the second driving device comprises a second steel wire rope, and a second motor, a second speed reduction box and a second dragging wheel which are in driving connection with one another in sequence; the counterweight device comprises a first counterweight device and a second counterweight device; the first steel wire rope is wound on the first dragging wheel; two ends of the first steel wire rope are connected with the first counterweight device and the top of the car respectively; the second steel wire rope is wound on the second dragging wheel; two ends of the second steel wire rope are connected with the second counterweight device and the top of the car respectively; the first counterweight device and the second counterweight device are symmetrically arranged on the outer side opposite to the car; the first dragging wheel and the second dragging wheel are same in rotation speed and opposite in rotation direction.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a new type elevator with double distribution. Background technique [0002] Elevators are an essential means of transportation for high-rise buildings, but the existing elevators often have safety problems, and even become murderers. How to realize the safety of elevators is a key point in elevator design. [0003] The existing elevator hangs the car and a counterweight through both ends of the wire rope, and then drives the wire rope through the traction sheave, so as to realize the rise or fall of the car. This design is only connected to the top of the car through one end of the wire rope. It is difficult to control in an emergency, and elevator accidents are prone to occur, resulting in casualties of passengers, so a new type of safe elevator needs to be designed now. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a new...
