を支持するローラである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an emergency stop device for an elevator, particularly a clamping structure compatible with high-speed, large-sized elevators [Prior Art] Figs. For example, this is a conventional elevator emergency stop device similar to the one described in Japanese Patent Application Laid-Open No. 59-43782. In Figure 2, (1) is a guide rail installed apart from each other in the hoistway, and (2) is an emergency stop device for an elevator. (2a) is the upper frame that forms the upper part of car (2); (2b) is the lower frame that forms the lower part of car (2); (3) is the car that is placed between the guide rails (1); guide tools provided on the upper frame (2a) and the lower frame (2b) and movably engaged with the guide rail (1);
(4) Governor rope stretched near (2) basket, (
5) are shafts pivotally supported near the guide rail (1) of the lower frame (2b). (6) is an interlocking mechanism, consisting of a lever (6a) whose base is fixed to one shaft (5) and whose tip is held by the governor rope (4), and one end of which is attached to the base of the lever (6a) and the other end. is a transmission lever (6) fixed to the other shaft (5).
(7) constituted by rods (6c) pivotally mounted on the shaft (5) are respectively provided on the shaft (5) and have their bases connected to the shaft (5).
), the tip (7a) of which is located closer to the guide rail (1), is an operating lever (8) that is U-shaped and attached to the lower frame (
2b), a guide rail (1) is arranged in the U-shaped recess, and pressure springs (9) are provided corresponding to the guide rails (1) on both sides, respectively. A suppressor (10) is a distal end portion (7a) of an actuating lever (7), which is provided at each end of the opening portion, faces the guide rail (1), and has a slope whose lower end recedes from the guide rail (1).
A brake piece consisting of a wedge-shaped body supported by the guide rail (1) and the pressing body (9), (U) is the pressing body (9)
This roller is provided between the brake piece (10) and the brake piece (10) and supports the linear displacement of both.

い)が駆動される。The emergency stop device for a conventional elevator is constructed as described above.9 Under normal conditions, the operating lever (7) is held in the lowered position and there is a gap between the brake piece (10) and the guide rail (1) surface as shown in Fig. 4. As shown, voids are formed. Then, the car (2) moves up and down in the state shown in Figure 4, and the governor lobe (4) connected to the lever (6a) goes up and down together with the car (2), causing the governor lobe (4) to wind. A speed governor (not shown) is driven.

(1)と摩擦によってかご(2)の下降が制動される。Now, if the car (2) descends at a high speed exceeding a predetermined value, the regulator operates to restrict the descending movement of the governor rope (4). In this state, the car (2) is still descending, so the lever (6a) rotates counterclockwise in FIG.
). Then, when the brake piece (10) is inserted, the pressing spring (8) is pushed out and the brake piece (10) is pressed against the guide rail (1), and the car ( 2) the descent is braked.
L記のような従来のエレベータの非常止め装置において
2次に述べる問題点があった。すなわち非常止め装置の
摩擦力は制動片(10)の押圧力と。The conventional elevator emergency stop device such as the one described in L has the following problems. In other words, the frictional force of the emergency stop device is the pressing force of the brake piece (10).

のため押圧ばね(8)、押圧体(9)、制動片(10)
等の部材が大形化して、大きい設置スペースが必要とな
りエレベータにおける実装設計が困難になる。It is determined by the product of the friction coefficients of the brake piece (10) and the guide rail (1). As elevators become faster and larger,
Since the required braking force also increases, the pressing force also becomes a large value. For this purpose, the pressing spring (8), the pressing body (9), and the brake piece (10)
These members become larger and require a larger installation space, making it difficult to design their implementation in an elevator.

When the car descends too quickly, both the first clamping mechanism and the second clamping mechanism operate to clamp the guide rail. Further, both of the above-mentioned brake pieces slide on guide surfaces of different guide rails in a horizontal projection plane.

なる。In the emergency stop device for the elevator configured as described above, when the elevating body (2) descends at an excessive speed, the governor lobe (4)
When the downward movement of the lever (6a) of the first clamping mechanism (12) is rotated, the brake piece (13) is displaced upwardly. Furthermore, the rotation of the lever (6a) of the first clamping mechanism (12) is transmitted to the second clamping mechanism (14) via the connecting mechanism (16), causing the brake piece (15) to move upward. Both the first clamping mechanism (12) and the second clamping mechanism (14) operate together, and the guide rail (1) is clamped by the respective brake pieces (f3) and (15), and the elevating body (2) is In this way, the frictional force necessary for braking the elevating body (2) is dispersed between the two, so that the pressure springs (
The members such as 8) can be small, and both of the above members are arranged separately above and below the elevating body (2). Therefore, it can be easily mounted in the space shown in FIGS. 4 and 5 on the horizontal projection plane, and a space-efficient mounting design is possible.

装置を得ることができる。Further, the braking stop distance of the elevating body (2) by the emergency stop device is longer than the height of the elevating body (2), and is, for example, 3 to 8 m when the operating speed of the speed governor is 450 m/min. However, since both of the above-mentioned brake pieces (13x15) are arranged facing different guide rails (1) and guide surfaces (1b) in the horizontal projection plane, one of the brake pieces (13) and (15) may rub against each other. The other side will not rub against the guide surface (1b) again. Therefore, it is possible to obtain an emergency stop device for an elevator that provides stable braking force without fluctuations in the coefficient of friction and has high operational reliability.
この発明は以上説明したとおり、昇降体に上下に離れて
設けられて共に動作する第1挟圧機構。As described above, the present invention includes a first clamping mechanism that is provided vertically apart from each other on an elevating body and operates together.

られ制動信頼度を向上させる効果がある。A second clamping mechanism is provided, and both brake pieces are arranged to face different guide rail guide surfaces in a horizontal projection plane. As a result, the frictional force necessary for braking the elevating body is shared between the two, and members such as the 7 pressing springs can be downsized, resulting in good space efficiency and ease of mounting design. Furthermore, the two braking pieces mentioned above have the effect of improving braking reliability because the other brake piece does not rub again the guide surface that has been rubbed by one piece, thereby providing a stable braking action.
