Description

Elevator device {ELEVATOR DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vibration suppression apparatus for damping the shaking of a passenger car of an elevator, and more particularly to an elevator apparatus having a vibration damper installed in a passenger car.

7 is an elevational cross-sectional view showing a conventional elevator apparatus shown in Japanese Patent Laid-Open No. 3-18577, for example. 8 is an external view of a passenger car of a conventional elevator apparatus. In the figure, the passenger car 1 and the counterweight 2 are guided to the guide rails 5, which are straight on the hoistway, through the guide shoes 4, respectively, and ascend in the hoistway omitted from the drawing. A passenger car 1 is connected to one end of the rope 3, and a counterweight 2 is connected to the other end of the rope 3. The rope 3 is wound around a drive pulley 6 provided in a machine room, not shown, provided on the upper part of the hoistway.

In operation of the elevator apparatus, the drive pulley 6 rotates, and the passenger car 1 moves up and down accordingly. Regarding the operation of such an elevator device, a traction system in which driving force is transmitted by friction between the drive pulley 6 and the rope 3 as shown in FIG. 7 and a car not shown in the figure are shown. Winding drum system (1) is only widely used on drums hanging on ropes (3). The present invention is effective in either configuration.

In Fig. 8, the passenger is allowed to enter and exit the passenger car in accordance with the opening and closing of the car door 8 suspended by the car door opening and closing device 7 installed on the upper part of the passenger car 1.

In the elevator apparatus of such a configuration, in any of the traction system or the pulsating system, if the length of the rope 3 from the passenger car 1 to the drive pulley 6 is long, the passenger car is moved by the displacement of the rope 3. The magnitude of the fluctuation due to the load fluctuation of (1) is determined. When long ropes are used, such as an elevator device installed in a high-rise building, or when a small number of ropes having a small diameter are used due to the small size and space saving, the fluctuation caused by the load variation of the passenger car 1 is greatly increased. do.

In the elevator apparatus using synthetic fiber ropes and high-strength wire ropes as the ropes 3, the relative modulus of elasticity tends to decrease as compared with the current one, so that the passenger car 1 is more likely to swing. It is predicted.

In addition, in the prior art Japanese Patent Application Laid-Open No. 3-18577, the vibration isolator provided in the passenger car 1 has a mechanism for pressing the guide rail 5 from the passenger car 1. It is proposed to reduce the displacement and the shaking of the passenger car 1 by this.

However, in order to actually implement the above conventional example, there is a case where the installation space is insufficient and cannot be installed, or the weight of the passenger car 1 is excessively increased so that it cannot be installed.

In addition, as a method of reducing the displacement or fluctuation of the passenger car 1, countermeasures for increasing the number of the ropes 3 or increasing the diameter are considered, but there are problems due to the enormous cost increase.

This invention is made | formed in order to solve the above subjects, and an object of this invention is to obtain the elevator apparatus which does not require a large space, can be light weight and low cost, and can be reduced in cost.

Example 1.

1 is an enlarged external view of a part of an elevator apparatus according to a first embodiment of the present invention. In FIG. 1, a cam 8a is attached to an end of the upper outer side of the car door 8. When the door 8 is opened, the cam 8a pushes up one end of the lever 9a of the link mechanism 9. The lever 9a is supported by the bracket 9c so that rotation is possible. When the lever 9a is pushed up one end, the vibration damping member 9e is pressed against the guide rail 5. On the surface of the guide rail 5 of the vibration damping member 9e, a rubbing member (not shown) for increasing friction is fixed.

When the door 8 is closed, the lever 9a is pulled downward by the traction spring 9b, and remains in the standby position by the stopper 9d. In the standby position, there is a gap between the guide rail 5 and the damping member 9e, so that the damping action does not work.

For example, the conventional vibration suppression apparatus disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 3-18577 reduces the fluctuation by using a special pressurization device on a passenger car. In this method, however, the desired damping action can be obtained, but the installation space is large and the weight becomes heavy, resulting in a large cost.

On the other hand, the vibration damping apparatus of the present embodiment is connected to the car door opening and closing device of the passenger car and operates in accordance with the opening and closing operation of the car door 8 to press the vibration damping member 9e to the guide rail as the hoistway to suppress the shaking of the passenger car. .

In addition, the vibration isolator is a link mechanism 9 for suppressing the shaking of the passenger car by pressing the drawing member (not shown) installed on the vibration damping member 9e provided between the car door 8 and the guide rail 5 on the guide rail 5. ).

Analyzing the pressing force of the vibration damping member 9e to the guide rail 5, it is calculated that a friction force of about 10 kg or more is required in the case of an elevator of 80 m in a lifting stroke of a general 9 seater.

For this reason, the vibration damping apparatus of the present embodiment is connected to the car door opening and closing device of the passenger car originally provided in the elevator apparatus, and operates in accordance with the opening and closing operation of the car door 8 to move the vibration damping member 9e to the hoistway. Press to suppress rocking of the car.

Therefore, it is possible to achieve an elevator apparatus that can be made light in weight and low in cost without requiring a large space, and can be reduced in cost.

Example 2.

2 is a front view of a car door opening and closing device for explaining an elevator device according to a second embodiment of the present invention. 3 is a front view of the boarding gate device. Figure 4 is an enlarged view of the coupling member for coupling the car door and the boarding door viewed from above the hoistway.

In Fig. 2, the car door opening and closing device 7 is attached to the front upper part of the passenger car. The car door 8 suspended in the suspension port 7a is opened and closed by the electric motor 7c connected through the interlocking rope 7b.

At a predetermined position of the car door 8, a car door engaging member 8b as a damping member is provided at a position corresponding to the boarding door device 10. The car door coupling member 8b has a cross-sectional shape "c" shaped along the lifting direction of the passenger car.

In FIG. 3, the boarding gate device 10 is attached to the front upper part of the boarding gate. The boarding door 10b suspended between the suspension rail 10e with the roller 10c and the roller 10d is supported so that the suspension door 10b can move left and right along the suspension rail 10e. .

In the predetermined position of the boarding door 10b, the boarding door coupling member 10a as a damping member is provided in the position corresponding to the car door opening / closing apparatus 7. As shown in FIG.

The landing door coupling member 10a has a cross-section "c" shaped to extend along the lifting direction of the car.

The car door coupling member 8b and the boarding door coupling member 10a are coupled to each other as shown in FIG. 4 when the car is located in the cage. Then, when the car door 8 is opened and closed by the car door opening and closing device 7, the landing door 10b is also opened and closed in conjunction with the operation.

In this embodiment, the driving force of the electric motor 7c is enhanced to an appropriate strength. Therefore, when both doors 8 and 10 open and close, the driving force of the car door opening / closing apparatus 7, ie, the driving force of the electric motor 7c, is transmitted to the boarding gate 10b as a hoistway via the engaging members 8b and 10a. As a result, the shaking of the passenger car is suppressed.

In this embodiment, a rubbing member 8c for increasing the frictional force is provided between the car door engaging member 8b and the landing door engaging member 10a. The rubbing member 8c is provided on the open press surface 8b1 and the closed press surface 8b2 of the cross-section " c " shape of the car door engaging member 8b. As a result, the frictional force between the coupling members 8b and 10a increases, and thus the fluctuation of the car is further attenuated, and the fluctuation of the car can be attenuated even while the door is opened or closed or deployed.

Further, the wet rubbing member 8c may be provided on any of the car door engaging member and the landing door engaging member 10a. However, since the side of the car door coupling member 8b is shorter than that of the boarding door coupling member 10a, the side of the door door coupling member 10a can be installed at the door of the car door coupling member 10a.

In addition, the vibration damping device of the elevator of the present embodiment can only expect the damping attenuation due to the friction force corresponding to the weight of the door of the car door and the boarding door during the door opening, but the pressing force when the door is unfolded is the driving force of the electric motor 7c. You can operate it freely by adjusting.

In addition, in the present embodiment, the car door and the landing door have a plurality of rollers in which the suspension rail is inserted in the vertical direction. If there is a gap in the upper or lower part of the door, if the passenger car swings while the car door coupling member 8b and the boarding door coupling member 10b are engaged, the door moves in the range of the gap, causing rattling, shaking and noise. It may also damage the life of the equipment. Therefore, the rollers are arranged on the upper and lower portions of the rails for guiding the opening and closing of the doors, and the gaps are eliminated by sandwiching the rails. In addition, in this embodiment, the upper door rail is fitted, but it is needless to say that the same effect can be ensured even when the rail is installed at the lower part or the movement of the door in the vertical direction is suppressed.

Example 3.

5 is a front view of a car opening and closing device for explaining an elevator device according to a third embodiment of the present invention. In Fig. 5, the car door 8 is provided with a fixed clamping member 8d and a movable clamping member 8e as clamping devices. The distance between the fixed clamping member 8d and the movable clamping member 8e changes in the open state of the car door 8. On the opposing surface of the fixed clamping member 8a and the movable clamping member 8e, a rubbing member (not shown) is provided. In the case where the passenger car is not in the predetermined position, the fixed clamping member 8d and the movable clamping member 8e are wide open to allow the boarding door engaging member 10f as the clamping device to pass smoothly. The landing door coupling member 10f is a roller installed in a row along the lifting direction of the passenger car as shown in FIG.

On the other hand, when the car stops at a predetermined position and the car door 8 is opened, the gap between the two clamping members 8d and 8e is wide open at the start of the door opening. Then, as the car door 8 is opened, the cam 8f presses the movable clamping member 8e to approach the fixed clamping member 8d to tightly hold the landing door coupling member 10f. The shape of the cam 8f is determined so that the holding force of the movable clamping member 8e is kept constant even when the car door 8 is completely opened. By changing the shape of the cam 8f, the change in the holding force due to the magnitude of the holding force and the door position can be set freely.

The cam 8f moves according to the opening / closing operation of the car door 8 by the configuration of the link 8h connecting the pin 7d provided to the car door opening and closing device 7 and the pin 8g provided to the door 8. And to generate an appropriate clamping force.

When the movable clamping member 8e is clamping the landing door coupling member 10f, when the passenger car attempts to displace, the clamping part tries to slip, but the car door 8 and the landing door 10b of the passenger car move up and down. The car door 8 is configured such that the suspension rail 8i is fitted by the rollers 8j and 8k, and the boarding door 10b is fitted with the suspension rail 10e by the rollers 10c and 10d. This effectively exerts the damping effect of the shaking.
