Description

  The present invention relates to an elevator apparatus that can automatically adjust the mass of a counterweight or a car.

  FIG. 13 is a system diagram of a conventional counterweight and car. In an elevator in which the counterweight 101 and the car 102 are connected by the main rope 103 or the like, the main sheave 105 is rotated by the hoisting machine 104 and the main rope 103 is moved up and down to move the counterweight 101 or the rider. The car 102 moves up and down. The main rope 103 applied to the hoisting machine 104 is pulled by both the counterweight 101 side and the car 102 side. Conventionally, the mass of the counterweight 101 after installation is always constant, but the mass on the side of the car 102 varies depending on the number and amount of passengers and cargo. Therefore, the load of the hoisting machine 104 that moves the main rope 103 to the heavier side of the counterweight 101 and the car 102 is larger than the load when moving to the opposite side of the counterweight 101 and the car 102. It increases in proportion to the mass difference.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an elevator apparatus capable of automatically adjusting the weight of the counterweight or the car in the elevator after installation.

  According to the elevator apparatus of the present invention, the rope to which the car and the counterweight are connected, the sheave around which the rope is wound, the electric motor that drives the sheave, and the car or the counterweight are provided. A weight installation frame having an open-and-close type hard ball insertion rod and a discharge port; a stock yard for storing the hard ball; and a first transport unit for transporting the hard ball discharged from the discharge port to the stock yard; A second transport unit that carries the hard balls from the stock yard to the insertion port, a first counter that measures the number of hard balls discharged from the discharge port, and the number of hard balls inserted from the insertion port The second counter is provided.

  According to the elevator apparatus of the present invention, it is possible to provide an elevator apparatus that can automatically adjust the counterweight mass or the car mass after installation.

  The elevator apparatus according to the present embodiment includes a slidable elevator apparatus and an automatic weight adjusting apparatus.

  As shown in FIG. 1, the lift type elevator apparatus of the present embodiment includes a counterweight 1, a car 2, suspension vehicles 3 a and 3 b attached to the upper parts of the counterweight 1 and the car 2, respectively. A driving sheave 5 provided in the hoisting machine 4, a main rope 6, and a hoistway 7 are included. One end of the main rope 6 is fixed to the upper part of the hoistway 7, the suspension wheel 3 a of the car 2, the driving sheave 5, and the suspension wheel 3 b of the counterweight 1 are routed in this order, and the other end is again connected to the hoistway 7. It is fixed at the top. As a result, the difference between the tension on the side of the car 2 of the main rope 6 and the tension on the side of the counterweight 1 and the frictional force generated between the drive sheave 5 and the main rope 6 are balanced. The car 2 is driven in a slidable manner.

  Next, the automatic weight adjusting apparatus will be described in detail with reference to FIGS.

  FIG. 2 shows a schematic diagram of the automatic weight adjusting apparatus of the first embodiment of the present invention.

  In FIG. 2, a frame 9 for inserting a hard ball 8 for adjusting the weight is attached to the counterweight 1, and the frame 9 is provided with an openable / closable insertion port 10 and a discharge port 11 for inserting and removing the hard ball 8. It has been. A counter 12b for measuring the number of hard balls 8 entering the frame 9 is attached to the insertion port 10, and a counter 12a for measuring the number of hard balls 8 discharged from the frame 9 is attached to the discharge port 11. ing. Below the discharge port 11, a belt conveyor 14 a is provided as a first transport unit that transports the hard balls 8 to the stock yard 13 that stores the hard balls 8. In addition, a belt conveyor 14b with a plurality of rake dishes provided at regular intervals is provided as a second transport unit for transporting the hard ball 8 from the stock yard 13 to the insertion port 10. As the hard ball 8, for example, a commercially available ball can be used.

  Such an automatic weight adjusting device stores the hard ball 8 in the frame 9 and automatically adjusts the weight by adding and extracting the hard ball through the following route.

  The hard ball 8 stored in the frame 9 is discharged from the discharge port 11. The hard ball 8 discharged from the discharge port 11 is conveyed to the stock yard 13 by the belt conveyor 14a. After that, the belt is conveyed from the stock yard 13 to the insertion port 10 of the frame 9 by the belt conveyor 14 b and enters the frame 9.

  In the conventional counterweight 1, a plurality of detachable weights are attached. When adjusting the mass after installing the elevator, the weight of the counterweight 1 is adjusted by manually attaching and detaching the weight. However, in this embodiment, by adding / pulling out the number of hard balls in the frame, it is possible to adjust the mass without manually removing the weight of the counterweight 1.
