<p>Disclosed is an elevating system (1), the elevating system (1) comprising: a carriage elevating device (11) fixedly arranged at the upper end of a main body (A); a counterweight elevating device (12) arranged at the upper end of the main body (A) and corresponding to the carriage elevating device (11); a speed-changing mechanism (13) for changing the relative rotational speed between the carriage elevating device (11) and the counterweight elevating device (12); a load-carrying carriage (14) suspended below the carriage elevating device (11) via one end of a first steel cable (15) for carrying a load, with the load-carrying carriage (14) being elevated by means of the operation of the carriage elevating device (11) via the first steel cable (15); a second counterweight (18) suspended below the carriage elevating device (11) via the other end of the first steel cable (15), with the second counterweight (18) and the load-carrying carriage (14) being able to be balanced in terms of potential energy; and a first counterweight (16) suspended below the counterweight elevating device (12) via a second steel cable (17), with the first counterweight (16) being elevated by means of the operation of the counterweight elevating device (12) via the second steel cable (17). The speed-changing mechanism (13) changes the rotational speed between the carriage elevating device (11) and the counterweight elevating device (12) such that the potential energy between the load to be carried by the load-carrying carriage (14) and the first counterweight (16) is balanced. The elevating system is able to greatly reduce mechanical energy.</p> |
