Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope gripping mechanism in an elevator governor for detecting an excess of traveling speed of an elevator car or counterweight.

[0002]

2. Description of the Related Art In elevators, as a safety device, an emergency stop is automatically stopped when the car speed exceeds a specified value according to Article 129-10 of the Building Standard Act Enforcement Ordinance. Provision of a device is specified.

FIG. 11 shows a schematic structure of a general elevator provided with an emergency stop device. An elevator car 1 is hung by a main rope 2 and is lifted and lowered in a hoistway by a hoist (not shown). At the same time, the guide rail 3 provided in the hoistway guides the hoisting and lowering.

An emergency stop device 4 is attached to the car 1. The emergency stop device 4 cuts the main rope 2 or the rotation speed of the hoisting machine becomes abnormal, and the speed of the elevator car 1 is rated. When the speed is exceeded, the guide rail 3 is gripped and the car 1 is mechanically stopped.

That is, when the speed governor 5 provided in the machine room detects the overspeed of the elevator, the speed governor rope grip 6 incorporated in the speed governor 5 is activated, and the speed governor 5 is integrated with the car 1. The traveling speed governor rope 7 is gripped.

The governor rope 7 has an endless shape, the upper part is wound around the sheave 5a of the governor 5, and the lower part is provided with a weight 7b via a pulley 7a. When the car 1 is moved up and down, it travels in the same direction as the car 1 at the same speed and between the sheave 5a and the pulley 7a of the governor 5.

When the speed governor 5 detects the overspeed of the car 1, the speed governor rope 7 is gripped by the speed governor rope grip 6 and its traveling is stopped, and in response to this stop, the car 1
The safety device 4 is operated via the safety link 8 attached to the car 1, and the car 1 is stopped.

FIG. 12 shows the structure of a general governor 5 used for a high speed elevator. Generally, the speed governor 5 includes a rotary weight 9 that generates a centrifugal force by rotating in association with a sheave 5a around which a speed governor rope 7 is wound,
An upper speed governor link 10a that is connected to the rotary weight 9 and moves according to a change in centrifugal force, and a speed adjusting spring that controls the motion of the upper speed governor link 10a and adjusts the motion speed of the speed governor 5. 11 and a speed governor rope grip 6 that operates by the lower speed governor link 10b and grips the speed governor rope 7.
It is composed of a fixed-side rope grip 12 that faces the speed governor rope grip 6 and grips the speed governor rope 7, and a grip spring 13 that applies a predetermined gripping force to the speed governor rope grip 6.

The speed governor rope grip 6 is shown in FIGS.
As shown in FIG. 4, the arm member 14 is connected to one end of the arm member 14 by a connecting portion 15 made of a pin, and is supported rotatably in the vertical direction around the pin as the connecting portion 15.

The other end portion of the arm member 14 slidably penetrates a rotary shaft 16 as a fulcrum portion rotatably attached to the bracket 16a, and rotates in the vertical direction integrally with the rotary shaft 16. It is possible to move. The grip spring 13 is incorporated on the outer periphery of the arm member 14. The grip spring 13 is interposed between a receiving member 14a provided on the end portion on one end side of the arm member 14 and a receiving member 16b provided on the rotary shaft 16. It should be noted that the arm member 14 is prevented from coming off from the rotary shaft 16 by a nut 14b.

When the speed governor 5 operates, that is, the speed governor rope 7 travels at an excessive speed integrally with the car 1, the rotational speed of the sheave 5a increases, and the rotary weight 9 is caused by centrifugal force. When the lower speed governor link 10b is opened and the lower speed governor link 10b is operated, the speed governor rope grip 6 together with the arm member 14 is rotated by the operation.
, And the speed governor rope grip 6 contacts the speed governor rope 7 via the shoe member.

With this contact, the speed governor rope grip 6 is further pulled downward by the speed governor rope 7 due to the frictional force between the speed governor rope grip 6 and the speed governor rope 7. 7 is the governor rope grip 6 and the fixed-side rope grip 1
It is gripped with 2.

The speed governor rope grip 6 is pulled downward,
When gripping the speed governor rope 7 with the fixed-side rope grip 12, the speed governor rope grip 6 moves to the rotary shaft 16 side together with the arm member 14 and presses the grip spring 13, and at this time, the grip spring The reaction force of the pressing force of 13 is transmitted to the governor rope grip 6 as a gripping force via the connection portion 15.

When the governor rope grip 6 is pulled downward by a predetermined amount of movement, the governor rope grip 6 is attached to the substrate 1
7, the descending motion stops and the gripping spring 1 at this time
The pressure reaction force of 3 causes the speed governor rope grip 6 to grip the speed governor rope 7 with a predetermined gripping force.

Through this series of operations, the speed governor rope grip 6 grips the speed governor rope 7 with a predetermined force, operates the safety device 4 via the safety link 8, and stops the car 1.

[0016]

However, the operating speed is
In the case of an ultra-high speed elevator exceeding 600 m / min, the traveling speed of the governor rope 7 also becomes high, so the friction coefficient between the governor rope grip 6 and the governor rope 7 decreases. The performance of the speed governor rope grip 6 entering the fixed-side rope grip 12 side deteriorates, and it becomes difficult to reliably grip the speed governor rope 7.

The following conditions can be considered in order to improve the entry performance of the speed governor rope grip 6.

1. Increase the friction coefficient between the governor rope grip and the governor rope.

2. Reduce the angle of the arm member when the governor rope grips contact the governor rope.

As described above, when the speed governor rope grip 6 contacts the speed governor rope 7, the speed governor rope grip 6 is generated by the frictional force f between the speed governor rope 7 and the speed governor rope grip 6. Is drawn downwards. At this time, the governor rope grip 6 presses the grip spring 13, so that the rope gripping force P acts on the governor rope grip 6 via the connecting portion 15. When the frictional force f at this time is larger than the reaction force due to the rope gripping spring force P, the governor rope grip 6 is pulled downward.

Assuming that the friction coefficient is μ and the angle formed with the horizontal plane of the arm member 14 is θ, the frictional force f is expressed as f> Psin θ f = μP cos θ by the balance of forces, so that the speed governor rope gripping is performed. The condition that 6 enters is μPcos θ> Psin θ μ> sin θ / cos θ = tan θ.

That is, the penetration performance can be improved by increasing the friction coefficient or decreasing the angle of the arm member 14 when the speed governor rope contacts. Table 1 below shows specific values of the friction coefficient μ and the angle θ of the arm member 14.
It becomes the street.

[0023]

[Table 1]

From this table, the minimum friction coefficient required for the speed governor rope 7 to pull the speed governor rope grip 6 downward is about 2 when the angle θ of the arm member 14 is changed from 12 ° to 8 °. It can be seen that the angle becomes / 3, and the entry performance of the governor rope grip 6 is improved by reducing the angle θ of the arm member 14.

On the other hand, it is extremely difficult to obtain a high friction coefficient in the ultra-high speed range, and as the friction coefficient increases, the aggression to the speed governor rope 7 increases, so there is a limit to increasing the friction coefficient. .

Since the rope gripping mechanism must be arranged within the parallel pitch H of the speed governor ropes 7, the arm member 1
The radius of gyration of 4 cannot be arbitrarily large. For this reason, when the angle θ of the arm member 14 when contacting the speed governor rope 7 is reduced, the stroke of the grip spring 13 is also reduced, and the shoe material of the speed governor rope grip 6 is worn or machined, and there is an error in assembly or the like. Is strongly affected, and it becomes difficult to continuously generate a stable gripping force.

On the other hand, in the super high speed elevator as described above, it takes about 50 m until the governor rope grip 6 operates and the car 1 is stopped by the safety gear 4. 7 slides on the rope gripping portion at a high speed, and there is a problem that the amount of wear of the shoe material of the speed governor rope gripping 6 increases.

When the amount of wear of the shoe material becomes large, the grip spring 13 cannot be compressed in a predetermined stroke,
It becomes difficult to continuously generate a stable gripping force, which may cause a problem such as inoperability of the safety device 4. For this reason, it is necessary to make the stroke of the grip spring 13 particularly large in an ultra-high speed elevator.

From the above, the speed governor rope grip 6
When an attempt is made to construct a rope gripping mechanism in which the angle of the arm member 14 is small and the stroke of the gripping spring 13 is large when the speed governor rope 7 comes into contact with the speed governor rope 7, the overall structure of the rope gripping mechanism becomes large, and as a result Machine 5 gets bigger.

For this reason, it becomes difficult to dispose the speed governor 5 in the determined machine room space, and the manufacturability and handleability deteriorate.

The present invention has been made paying attention to such a point, and an object thereof is to determine the angle of the arm member when the rope grip and the governor rope contact each other without increasing the size of the structure. It is an object of the present invention to provide a rope gripping mechanism for an elevator speed governor that can be made small and can have a large stroke of the gripping spring, and can always generate a stable gripping force accurately.

[0032]

According to a first aspect of the present invention, a speed governor rope grip is rotatably attached to a distal end portion of an arm member rotatable about a fulcrum portion via a connecting portion. ,
During operation of the speed governor of the elevator, the speed governor rope grip contacts the speed governor rope, and the arm member rotates about the fulcrum portion, and the arm member is provided on the arm member along with the rotation. In the rope gripping mechanism of an elevator speed governor, the gripping spring is pressed by the speed governor rope grip and the speed governor rope grips grips the speed governor rope by the reaction force of the pressing. It is characterized in that the connecting portion for connecting with the member is located on the opposite side of the fulcrum portion of the arm member with the governor rope as a boundary.

The invention according to claim 2 is characterized in that the speed governor rope grip is U-shaped, and an inspection hole is formed on a side surface of the U-shaped speed governor rope grip.

It is characterized in that an elastic body is provided which gives a rotational movement in the direction.

[0037]

1 and 2 show the first embodiment. The difference between the rope gripping mechanism in this embodiment and the conventional one is that the connecting portion 15 between the arm member 14 and the speed governor rope grip 6 is different. Is located on the front side of the governor rope 7, that is, on the opposite side of the rotating shaft 16 which is the fulcrum of the arm member 14 with the governor rope 7 as a boundary.

To explain further, the arm member 14 has a bracket 21 having a U-shape in plan view at the end portion on the opposite side of the rotary shaft 16 as shown in FIG. A speed governor rope grip 6 having a U-shaped view is provided.

The connecting parts 15 are coaxially connected to each other, and the speed governor rope grip 6 is supported via the connecting parts 15 so as to be rotatable in the vertical direction with respect to the bracket 21.

A speed governor rope 7 and a fixed-side rope grip 12 are arranged inside the U-shaped speed governor rope grip 6, and the speed governor rope grip 6 attaches the shoe member 22 to the speed governor rope 7. Through contact. The position of the connecting portion 15 is located on the opposite side of the rotation shaft 16 which is the rotation center of the arm member 14 with respect to the speed governor rope 7.

With this configuration, the arm member 14 can be maintained without changing the position of the rotary shaft 16 or the parallel pitch H of the speed governor ropes 7.
The turning radius of can be increased.

As shown in FIG. 3 (A), the radius of gyration of the arm member 14 is R, and the angle between the governor rope grip 6 and the horizontal surface of the arm member 14 when the governor rope 7 comes into contact with the governor rope 7. Assuming θ, the width of the stroke δ pressing the grip spring 13 is δ = R (1−cos θ).

FIG. 3B shows the structure of the conventional case, in which the radius of gyration of the arm member 14 is R ', and the arm member 14 when the governor rope grip 6 contacts the governor rope 7. The angle of the stroke δ ′ pressing the gripping spring 13 is δ ′ = R ′ (1-cos θ), where θ is the angle formed with the horizontal plane.

Here, R> R ', and therefore δ>
δ ′, and in this embodiment, the width of the stroke δ that presses the grip spring 13 can be sufficiently secured,
This makes it possible to reduce the angle θ of the arm member 14 when the speed governor rope grip 6 comes into contact with the speed governor rope 7, enhances the entry performance of the speed governor rope grip 6, and provides a stable gripping force. The rope gripping mechanism that occurs can be configured.

Connection part 1 between speed rope grip 6 and arm member 14
The position 5 can be easily arranged in front of the governor rope 7.

Further, since the governor rope grip 6 is U-shaped, its planar area is large, and therefore, the collision stress when the governor rope grip 6 collides with the substrate 17 can be relieved. Therefore, it is possible to prevent generation of indentations on the speed governor rope grip 6 and the substrate 17.

As a result, even if the operation of the speed governor rope grip 6 is repeated, the rotational momentum of the arm member 14 can be maintained at a predetermined value, and the durability of the speed governor rope grip 6 can be improved. it can.

Further, since the speed governor rope grip 6 is U-shaped, the speed governor rope grip 6 covers the part that grips the speed governor rope 7, and occurs when the speed governor rope 7 is gripped. It is possible to prevent the abrasion powder of the shoe material 22 and the oil etc. of the speed governor rope 7 from scattering, the cleaning after the rope gripping operation is reduced, and the malfunction of the speed governor mechanism portion due to these scattered objects is prevented. It can be prevented. Especially in the super high speed elevator, the speed governor rope 7 during the rope gripping operation
The speed is also very high, and the speed governor rope grip 6 and the board 17
The impact speed becomes even higher, and the amount of scattered matter at the time of gripping the speed governor rope also increases, so that the effect becomes more effective.

FIG. 4 shows a second embodiment. In this embodiment, an inspection hole 24 is formed on the side surface of the speed governor rope grip 6 having a U shape.

If the speed governor rope grip 6 is U-shaped, the speed governor rope grip 6 covers the grip portion of the speed governor rope 7, so that the speed governor rope 7 during gripping operation of the speed governor rope 7 is covered. Although it becomes difficult to confirm the gripped state, the worn state of the shoe member 22, and the like, according to the present embodiment, the gripped state of the speed governor rope 7 and the shoe material are checked through the inspection hole 24 on the side surface of the speed governor rope grip 6. The wear state of 22 and the like can be easily confirmed, and an abnormality in the rope gripping operation can be easily found visually.

Further, it is possible to confirm the worn state of the shoe member 22 and to clean the shoe member 22 without removing the speed governor rope grip 6 and the shoe member 22. Therefore, adjustment of the rope grip portion, maintenance work, and the like can be easily performed, and maintenance work can be reduced.

Furthermore, by forming the inspection hole 24, it is possible to reduce the weight of the speed governor rope grip 6,
The collision stress when the governor rope grip 6 collides with the board 17 can be reduced, and the governor rope grip 6 and the board 1 can be reduced.
It is possible to more reliably prevent the generation of indentations due to the collision of the gear 7, and it is possible to further enhance the durability of the speed governor rope grip 6.

FIG. 5 shows a third embodiment. In this embodiment, a flange 25 is formed on the lower portion of the side surface of the U-shaped governor rope grip 6 and the flange 25 is formed.
A screw 26 is screwed in as a rope grip releasing means. Then, the speed governor rope grip 6 grips the speed governor rope 7, and the screw 26 is screwed in while the flange 25 abuts against the upper surface of the substrate 17, thereby lifting the speed governor rope grip 6 upward. The grip of the governor rope grip 6 with respect to the governor rope 7 can be released.

Conventionally, in order to release the grip of the governor rope grip 6, a clearance for inserting a releasing tool is secured in advance between the governor rope grip 6 and the board 17, or the governor rope grip 6 is held. 6 is provided with a hanging portion, and these portions are used to lift the speed governor rope grip 6 with a releasing tool such as a burl to release the grip.

However, it is necessary to handle a long tool, a crowbar, within a defined space in the machine room, and other equipment or beams in the machine room may interfere with the work, thereby controlling the speed. It often becomes difficult to release the grip of the machine rope grip 6.

However, in the present embodiment, the screw 26 can be formed by using a general small tool such as a spanner or a socket wrench without requiring a special releasing tool such as a burl.
By operating, the grip of the governor rope grip 6 can be easily and efficiently released.

Since the grip of the governor rope grip 6 can be released without disturbing other devices or beams in the machine room, rescue work for passengers and restoration work for the elevator after the rope grip operation is performed. It is possible to quickly perform the above.

FIG. 6 shows a fourth embodiment. In this embodiment, a balance weight 27 is attached to the side surface of the speed governor rope grip 6, and the speed is adjusted by the balance weight 27. The position of the center of gravity G of the machine rope grip 6 is deviated to the front side of the arm member 14 from the support portion 15.

In the conventional speed governor rope grip 6, as shown in FIG. 7 (A), the speed governor rope grip 6 and the arm member 1 are provided.
4 from the position of the speed governor rope 7
It is on the inside of the 6 side, and therefore the speed governor rope grip 6
Tries to rotate in a direction in which the upper side of the speed governor rope grip 6 approaches the speed governor rope 7 and the lower side moves away from the speed governor rope 7, that is, counterclockwise around the connecting portion 15. A stopper 28 is attached to the lower portion of the arm member 14 for restricting the rotational movement and supporting the governor rope grip 6. The speed governor rope grip 6 is in a stable state at a position where it contacts the stopper 28, and is held at a predetermined initial position.

Further, as shown in FIG. 7B, when the speed governor rope grip 6 operates and the arm member 14 makes a rotational motion and the speed governor rope grip 6 contacts the speed governor rope 7, The speed rope grip 6 rotates in the direction away from the stopper 28,
Grasp the governor rope 7.

However, in the rope gripping mechanism according to the first embodiment, as shown in FIG. 8, the position of the connecting portion 15 between the speed governor rope grip 6 and the arm member 14 is located in front of the speed governor rope 7. The position of the center of gravity G of the speed governor rope grip 6 is on the rear side of the connection portion 15, and therefore the speed governor rope grip 6 tends to rotate clockwise around the connection portion 15.

Here, as in the conventional case, the speed governor rope grip 6
When the rotational movement of the above is attempted to be restricted by the stopper, the stopper 28 is attached to the upper portion of the arm member 14 as shown in FIG.

However, with this configuration, when the rope gripping mechanism operates and the arm member 14 and the governor rope grip 6 rotate to cause the governor rope grip 6 to grip the governor rope 7. Moreover, the rotational movement of the speed governor rope grip 6 is restricted by the stopper 28, and the speed governor rope 7 cannot be gripped.

On the other hand, in the fourth embodiment shown in FIG. 6, the position of the center of gravity G of the speed governor rope grip 6 is ahead of the connecting portion 15 by the balance weight 27, so that the speed governor rope grip is held. 6 tries to make a rotational movement in the counterclockwise direction as in the case of FIG.
A stopper 28 is provided at the lower part of the speed governor rope 7 so that the speed governor rope grip 6 can be appropriately rotated when gripping the speed governor rope 7.

FIG. 9 shows a fifth embodiment. In this embodiment, the position of the center of gravity G of the speed governor rope grip 6 is on the front side of the arm member 14 with respect to the support portion 15, and the adjustment is performed. A plurality of screw holes 30 are formed on the side surface of the speed rope grip 6 on the front side of the connecting portion 15, and the weight 3 for balancing is provided in any screw hole 30 via a screw 31.
2 is detachably attached, and further, a stopper 28 that restricts the rotational movement of the governor rope grip 6 in the counterclockwise direction is attached to the lower portion of the arm member 14.

The shoe member provided inside the speed governor rope grip 6 may need to be changed in material and shape depending on the application speed of the speed governor. In this case, the change also changes the position of the center of gravity of the governor rope grip 6. In order to deal with this, a plurality of governor rope grips 6 having a center of gravity at a position corresponding to each applied speed must be manufactured and prepared in advance.

However, in the fifth embodiment, it is only necessary to select a plurality of screw holes 30 formed on the side surface of the speed governor rope grip 6 and change the mounting position of the balance weight 32. The center of gravity of the speed governor rope grip 6 can be adjusted, and the weight 32 for balancing with different masses is provided.
It is also possible to adjust the position of the center of gravity of the speed governor rope grips 6 by attaching the speed governor rope grips 6, and thus it is not necessary to manufacture and prepare a plurality of speed governor rope grips 6 having different positions of the center of gravity in advance. A kind of governor rope grip 6
It is possible to deal with the change of the applied speed of the governor by using only the common.

Even if the position of the center of gravity of the governor rope grip 6 fluctuates due to manufacturing errors or the like, it can be dealt with by simply adjusting the mounting position of the weight 32 for balancing. Therefore, the governor rope grip 6 It is possible to obtain a relatively large tolerance and the like at the time of manufacturing, so that the manufacturability can be improved and the cost can be reduced.

FIG. 10 shows a sixth embodiment.
In this embodiment, an elastic body 33 such as a tension spring is used.
The speed governor rope grip 6 is elastically urged in the counterclockwise direction by using, and its rotational movement is restricted by a stopper 28 provided at a lower portion of the arm member 14.

In this case, the speed governor rope grip 6 can be held at a proper initial position without providing a balancing weight or the like on the speed governor rope grip 6. Since no weight or the like is required, the structure is simple and the manufacturability can be improved. A compression spring may be used as the elastic body 33.

[0073]

As described above, according to the present invention, the angle of the arm member when the rope grip and the governor rope contact each other can be reduced and the stroke of the grip spring can be increased without increasing the size of the structure. Therefore, a stable gripping force is always generated accurately and high reliability is obtained.
