Abstract

The invention discloses a compensating device for an elevator driven by double main engines. The compensating device comprises at least one car platform pulley, a pulley block and a connecting mechanism; the car platform pulley is fixedly arranged at the bottom of an elevator lift car; the pulley block comprises a first pulley block body and a second pulley block body which are arranged in a liftway pit; and one end of the connecting mechanism is fixedly connected with a first counter-weight bottom of the elevator, and the other end of the connecting mechanism vertically bypasses the first pulley block body, the car platform pulley and the second pulley block body sequentially and finally is fixedly connected to a second counter-weight bottom of the elevator. By means of the compensating device, the problem that the compensating device is prone to being damaged when the double main engines of the elevator operate asynchronously is solved, and the problem that the single main engine of the elevator cannot be compensated is also solved.

Description

technical field [0001] The invention relates to a compensating device for an elevator. More specifically, the present invention relates to a compensating device for an elevator driven by two main engines. Background technique [0002] Traditional elevators are generally driven by a single main engine. When the running speed is high or the load is large, the volume of the main engine will become very large, and the cost of the main engine will increase exponentially, and it will also cause It is difficult to install and cannot meet the requirements of high speed and large load capacity at the same time. The related patent CN104760870A discloses a dual-host drive elevator, which uses two traction machines as drives, and is correspondingly equipped with two counterweights, which are respectively located on both sides or the same side of the elevator car. The double-host synchronously driven elevator has the advantages of large load capacity, high speed, simple structure and r...
