る。The conventional linear motor drive elevator is configured as described above. For example, when lowering the elevator car (6), a multi-layer AC voltage is applied to the linear motor-secondary winding (9) to energize the primary winding (6). In 9), a magnetic field moving from bottom to top is generated. Thus, the counterweight (8) is driven upward,
As a result, the car (6) is driven down through the main rope (4). Next, when the car (6) reaches the lower vicinity of the target floor, the linear motor primary winding (9) is de-energized and the brake device (10) is operated to operate the car (6) and the counterweight (8).
Is stopped. Also, by generating a magnetic field moving from the top to the bottom in the linear motor primary winding (9), the car (6)
The car (6) is moved up by the same action as when the car is moved down.

で停止されることとなる。During the above-described driving operation, the brake device (10) is specifically operated as follows. First, the brake device (10) is engaged while the car (6) is stopped. Then the basket (6)
To start driving the vehicle, at point a in Fig. 5, select the braking device (1
At the same time that (0) is opened, the linear motor primary winding (9) is energized. After the point a, while the car (6) is traveling, the primary winding (9) of the linear motor is continuously energized and the brake device (10) is opened. When the car (6) reaches the vicinity of the destination floor, for example, at the point d, the application of the multi-layer AC voltage to the linear motor next winding (9) is interrupted and deenergized, and at the same time, the brake device (10) is engaged, thus The car (6) will be stopped at point e.

It shows the state. In this state, the pull rod (15) is pulled down, and the wedge metal (13) is kept in a predetermined gap with respect to the car rail (5). When it is detected that the speed of the car (6) is abnormally higher than the rated speed, the pull rod (15) is suddenly pulled up as shown in FIG. It is pushed into the taper of (12), the inner surface of the wedge metal (13) is strongly pressed against the car rail (5), and the car (6) suddenly stops due to the frictional force.

である。The present invention will be described below with reference to the embodiments shown in FIGS. In the drawings, the same reference numerals as those in FIGS. 4 to 7 denote the same or corresponding parts, and (16) is a braking mechanism newly provided below the car (6), which has the structure shown in FIG. There is. In the figure, (17) is a support pin fixedly provided on the bottom part (6a) of the car, and (18) has one end supported by the support pin (17) and a pulling rod ( A suction rod (20) attached to the bottom of the car (6a) by a compression rod (19) that is connected upward to a connecting rod that is coupled to the suction rod (15). ) Is attached. (21) is a suction coil installed around the suction member (20).

隙間が形成されてブレーキは開放されることとなる。In the linear motor drive elevator constructed as described above, since the suction coil (21) of FIG. 2 is deenergized when the car (6) is stopped, the compression spring (19) The connecting rod (18) is pushed upward, so that the wedge metal (13) is pressed against the car rail (5) with a force commensurate with the elastic force of the compression spring (19) to stop the car (6). Is retained. When operating the car (6), when the suction coil (21) is urged, the suction member (20) is sucked by the suction coil (21) and the connecting rod (18) is pulled down, whereby the wedge metal. A gap is formed between (13) and the car rail (5), and the brake is released.

てかご(6)を急停止させる。This operation corresponds to point a in FIG. 3, and the subsequent operation of the car (6) is performed in the same manner as the operation of the conventional linear motor. In the present invention, the operation is applied to the linear motor primary winding (9). Properly control the multi-layer AC voltage and stop the car (6) at the correct destination floor position without shifting (6 points d and e in Fig. 3) only by electrical control, and immediately after that, attach the suction coil (21). The braking mechanism (16) is urged to operate, and the stopped state of the car (6) is reliably maintained. When the car (6) becomes overspeed in the event of an abnormality such as disconnection of the main rope (4), the braking mechanism (16) shown in Fig. 2 is similarly urged to rapidly pull the pull rod (15). Forcibly pull up the wedge metal (13) to the car rail (5), and stop the car (6) suddenly.

れも本発明が適用できることは言うまでもない。In the example of FIG. 4, the linear motor primary winding (9) is installed facing the counterweight (8), but the linear motor primary winding (9) faces the car (6). In such a case, the linear motor primary winding (9) may be mounted on the car (6) or the counterweight (8), but it goes without saying that the present invention is applicable to both.

きる。In the present invention, as described above, since the conventional brake device provided coaxially with the sheave in the machine room is not used,
It is not affected by the abnormal wear phenomenon that occurs between the sheave and the main ropes, and at the time of frequent normal stoppage,
Since the car is stopped by the electric control of the linear motor until the car stops, and the braking mechanism is used only to maintain the stopped state, this braking mechanism provided at the bottom of the car moves relative to the car rail. No friction and no abnormal wear. Further, when the car operates abnormally, this braking mechanism functions as an emergency stop device as in the conventional case, and it is not necessary to separately install the brake device and the emergency stop device as in the conventional case, and an elevator having a simple structure can be realized. .
