Abstract
The invention relates to a counterweight free lift system, which includes a car lifted in a shaft, a drive device, a hoisting rope and a hoisting rope wheel, and a plurality of pulleys, and is characterized in that: the car is a split-typed structure and uses body weight and load weight of the car as the counterweight to realize up-and-down motion of the car by the hoisting rope, a plurality of pulley rooms and one of the winding modes, wherein, at least two pulleys are arranged fixedly at two sides and the middle part on the upper part of the car frame, at least one pulley is fixed on the upper part of the body, the pulleys and the hoisting rope wheel are reciprocally vertical and correspondingly arranged on the upper part or the lower part of the shaft, one end of the hoisting rope is fixed at the fixing position on the upper part of the shaft, after winding the pulleys fixed on the car frame and the body in sequence, the terminal of the hoisting rope is fixed at the fixing positionon the lower part of the shaft. The invention does not require counterweight, which is an ideal lift product with economy, energy saving and novel and unique design.
Description
technical field [0001] The invention relates to a non-counterweight elevator system, specifically a kind of elevator car that does not need counterweight or counterweight, uses the weight of the elevator car itself and the weight carried by it as the counterweight, and realizes the lifting of the elevator car by surrounding the pulley with steel cables. up and down. Background technique [0002] The elevator system usually consists of a car system and a counterweight system that move up and down in the hoistway (hoist room). figure 1 is a schematic diagram of the prior art structure, figure 1 Indicates that the usual car is an integrated structure composed of two parts, the car frame 1 and the box body 2, where the box body 2 is supported by the car frame 1; the usual elevator system includes an elevator car, a driving device (traction machine) , traction rope (wire rope) and counterweight (counterweight); wherein the traction rope or other load-bearing parts move along pu...
