<p>The invention provides an improving method for existing elevator and an elevator device, wherein the improving method can modifying the direction connection type hydraulic elevator device into a rope type elevator device without the need of changing the size of the elevator cage. The hydraulic jack used in the direct connection type elevator device (22) is eliminated from the jack protection pipe(6), wherein the jack protection pipe (6) includes openings on the bottom surface (5a) of the bottom pit (5) of the well hole (1); a counterweight (7) is arranged in the internal space of the jack protection pipe (6), wherein hanging wheels (14) capable of free rotation are provide on the counterweight (7). Thereafter, one end of the main rope (8) is connected to the elevator cage (2), and the middle part of the main rope (8) is wound on the hanging wheel (14) pass the lateral rear side of the elevator cage (2), and the other end of the main rope (8) is connected to the fixing body of the well hole (1).</p> |
