されている。2. Description of the Related Art As a conventional elevator, for example, FIG.
There is something like. In the figure, reference numeral 101 is an elevator car that moves up and down in a hoistway of a building. One end of a rope 102 is fixed to the top surface of the car 101, and the other end of the rope 102 is a drive sheave 103,
It is fixed to the counterweight 105 via the deflecting sheave 104. The balance weight 105 is for balancing the car 101 in a slipping manner, and is set to a total weight of the weight of the car 101 and half of the rated load.

う問題点があった。The conventional counterbalance weight 105 of such an elevator is set to the total weight of the weight of the car 101 and half of the rated load (for example, the weight of a passenger who gets in). Therefore, at the time when many passengers use the elevator (for example, work time and leaving time), the counterweight 105 balances the car 101 with many passengers. However, since there are few passengers who use the elevator during the off hours other than the above time, the counterweight 105 side becomes heavier and unbalanced, and the load on the hoisting machine increases. For this reason, when the car 101 is moved up and down by the hoisting machine during a quiet period, the output of the hoisting machine becomes large, and the energy used becomes large, which is uneconomical.
【０００５】本発明は、閑散時にも釣り合い重りの重量

とを目的とする。It is an object of the present invention to provide an elevator counterweight device which balances the weight of the counterweight with the weight of the car even when the vehicle is in a quiet state and reduces the load on the hoisting machine.

したりするようにした構成とする。In order to achieve such an object, according to the present invention, a counterweight, which is arranged in a hoistway in such a manner as to balance a cage, and which comprises a main body portion and an additional portion, A hook member that is movably attached to the main body of the counterweight and that can suspend the additional portion; and a moving unit that moves the hook member. The moving unit moves the hook member, and The configuration is such that the additional portion is suspended from the main body portion in the front or is removed from the suspended state.

小さくなり、かごとバランスよく釣り合う。In the off-season, the number of passengers boarding is reduced, and the weight of the car to which the passengers are added is reduced. For this reason, it is necessary to balance the basket and the weight of the counterweight so that a large load is not applied to the hoisting machine. Therefore, the hook member is moved by the moving means at the time of the quiet time, and the additional portion of the counterweight is removed from the state suspended from the main body portion. This will reduce the weight of the counterweight and balance the basket and balance.

4, 25 move so as to project from the drive shafts 22, 23. When the movable shafts 24 and 25 project and move, the hook members 30 and 31 are disengaged from the engaged members 36 and 37, the additional portion 3 is no longer suspended from the main body portion 2, and the weight of the counterweight 1 is reduced. Get smaller. Then,
The weight of the balance weight 1 is balanced with the weight of the reduced car in a well-balanced manner, and the load applied to the drive means such as a hoist for moving the car up and down is reduced.

Since the hook member is moved by the moving means so that the additional part of the counterweight is hung on this main body part or removed from this hung state, the balance weight can be balanced well with the cage even in the case of off-season. You can
The load on the drive means for moving the car up and down is reduced. Therefore, the output of the driving means may be small,
As a result, this energy consumption can be saved and it is economical.
