Description
Technical Field
The present invention relates to an emergency rescue tool for an elevator apparatus including a compensating cable, and an elevator apparatus.
Background
A so-called sling elevator is known in which an elevator car is suspended at one end of a main sling and a counterweight is suspended at the other end, and the elevator car and the counterweight are lifted and lowered by frictionally driving the main sling with a hoist. In such a sling elevator, when a passenger is rescued from an elevator car that has been stopped in an emergency, the passenger is generally rescued by moving the elevator car to a rescuable position by releasing the brake using an unbalanced mass between the elevator car side mass and the counterweight side mass. However, when the mass on the elevator car side and the mass on the counterweight side are in a balanced state at the time of emergency stop, the elevator car does not move even if the brake is released.
In contrast, patent document 1 discloses the following method: in an elevator device provided with a compensation chain connected between the lower part of an elevator car and the lower part of a balance weight, when the elevator device is in emergency stop, a weight is suspended on the compensation chain to move the elevator car, thereby rescuing passengers.

1-2. apparatus for emergency rescue
Fig. 2 is a schematic configuration diagram of the emergency rescue tool 20 according to the present embodiment as viewed from above. Fig. 3 is a schematic configuration diagram of the emergency rescue tool 20 according to the present embodiment when viewed from the side.
As shown in fig. 2, the emergency rescue tool 20 includes a first bracket 21a, a second bracket 21b, a fastening body 22 for fastening the first bracket 21a and the second bracket 21b to each other, and locking portions 23a and 23b for locking a weight, which will be described later. The first bracket 21a and the second bracket 21b are members fixed to the compensating cable 5 so as to sandwich the compensating cable 5.
The first bracket 21a is made of a plate-shaped steel material having a predetermined thickness dimension, and includes a clamping portion 21a1 and a bent portion 21a 2.
The clamping portion 21a1 is formed by one end portion side of a plate-like member constituting the first bracket 21a, and has a mountain-shaped bent portion 24 at its middle portion. The curved portion 24 has a concave surface 24a (corresponding to a concave portion of the present invention) having a triangular cross section on one surface. Bolt holes (not shown) through which fixing bolts 22a described later are inserted are provided on both sides of the bent portion 24 of the clamping portion 21a 1. Here, the "cross section" of the bent portion 24 refers to a surface in a direction perpendicular to the extending direction of the compensating cable 5 when the first bracket 21a is attached to the compensating cable 5.
On the other hand, the bent portion 21a2 is formed by bending the other end portion of the plate-like member constituting the first bracket 21a to the side opposite to the side of the curved portion 24 on which the concave surface 24a is formed. In the present embodiment, the bent portion 21a2 is formed by bending a plate-shaped member by, for example, 90 degrees. Further, the bent portion 21a2 is provided with a hole 23a1 serving as an engaging portion 23 a.
In this way, the sandwiching portion 21a1 and the bent portion 21a2 constituting the first bracket 21a are formed by bending one plate-shaped member and are integrated with each other.
The first bracket 21a having such a shape is disposed on one side of the side surface portion of the compensation cable 5 so that the compensation cable 5 abuts against the concave surface 24a of the bending portion 24.
The second bracket 21b is formed in the same shape as the first bracket 21a, and has a clip 21b1 and a bent portion 21b2 in the same manner as the first bracket 21a, and the clip 21b1 is provided with a bent portion 25 having a concave surface 25a with a triangular cross section. Further, the bent portion 21b2 is provided with a hole 23b1 serving as an engaging portion 23 b.
The configurations of the grasping portion 21b1, the bent portion 25, and the bent portion 21b2 in the second bracket 21b are the same as those of the grasping portion 21a1, the bent portion 24, and the bent portion 21a2 in the first bracket 21a, respectively, and therefore, a repetitive description thereof will be omitted.
The second bracket 21b is disposed on the other side of the side surface portion of the compensation cable 5 so that the compensation cable 5 abuts against the concave surface 25a of the curved portion 25. The second bracket 21b is disposed such that the engagement portion 23b thereof is in a position point-symmetrical to the engagement portion 23a of the first bracket 21a with respect to the compensation cable 5.
The fastening body 22 is composed of a fixing bolt 22a inserted through bolt holes of the first bracket 21a and the second bracket 21b arranged so as to sandwich the compensating cable 5, and a fixing nut 22b and a washer 22c attached to the tip of the fixing bolt 22 a. In the present embodiment, the first bracket 21a and the second bracket 21b are fixed to both sides of the respective bent portions 24 and 25 by the fastening body 22.
1-3 passenger rescue method in emergency
Next, a method of rescuing passengers from the elevator car 1 at the time of emergency stop of the elevator apparatus 100 will be described. Fig. 4 is a schematic perspective view showing a state in which the emergency rescue tool 20 is attached to the compensating cable 5, and fig. 5 is a structural view of the S-hook 50 used when the weight 60 is attached to the emergency rescue tool 20.
When the elevator apparatus 100 is brought into an emergency stop and the mass on the elevator car 1 side and the mass on the counterweight 2 side are in a balanced state, the emergency rescue tool 20 is attached to the compensating cable 5 so that the mass on the elevator car 1 side and the mass on the counterweight 2 side become unbalanced in order to rescue passengers from the elevator car 1. In the present embodiment, in order to move the elevator car 1 to the lower floor, an example is adopted in which the emergency rescue tool 20 is attached to the lower side of the elevator car 1 and is closer to the elevator car 1 side than the bent portion of the compensating cable 5.
In this case, first, the first bracket 21a is disposed on one side of the compensating cable 5 so that the compensating cable 5 abuts against the concave surface 24a of the curved portion 24. Next, the second bracket 21b is disposed on the other side of the compensating cable 5 so that the compensating cable 5 is in contact with the concave surface 25a of the curved portion 25, opposite to the first bracket 21 a. That is, the first bracket 21a and the second bracket 21b of the emergency rescue tool 20 are opposed to each other and the compensating cable 5 is sandwiched therebetween.
In this state, the fixing bolt 22a is inserted from the back side of the first bracket 21a and passed through the first bracket 21a and the second bracket 21b, and then the washer 22c is fitted to the tip of the fixing bolt 22a and the fixing nut 22b is screwed. By strongly fastening the fixing nut 22b, the emergency rescue tool 20 can be firmly attached to the compensating cable 5. In the present embodiment, the curved portion 24 of the first bracket 21a and the curved portion 25 of the second bracket 21b are formed in such a shape that the concave surface 24a and the concave surface 25a can press the periphery of the compensating cable 5 when the compensating cable 5 is sandwiched therebetween. This enables the emergency rescue tool 20 to be firmly fixed to the compensating cable 5.
After the emergency rescue tool 20 is attached to the compensating cable 5, the S-hook 50 shown in fig. 5 is hung on the locking portions 23a and 23b of the first bracket 21a and the second bracket 21b, respectively, and a weight 60 of a desired weight is hung on the S-hook 50. In this case, it is preferable that weights of the same weight be suspended in the locking portions 23a and 23b, respectively. Further, by attaching a string-like body 60a that can be hooked on the S-hook 50 as shown in fig. 4 to the suspended weight 60 in advance, the weight 60 can be easily suspended on the S-hook 50.
Through such steps, the emergency rescue tool 20 and the weight 60 are attached to a plurality of positions of the compensating cable 5 as necessary. In order to move the elevator car 1 by making the mass on the elevator car 1 side and the mass on the counterweight 2 side unbalanced, it is necessary to attach a certain amount of weight to the compensating cable 5. On the other hand, when all the necessary weights 60 are attached to one emergency rescue tool 20, an excessive load is applied to a predetermined portion of the compensating cable 5 due to the fastening of the emergency rescue tool 20 and the load of the weights 60, and the compensating cable 5 may be damaged. Therefore, by dispersedly attaching the emergency rescue tool 20 and the weight 60 to the compensating cable 5, the damage of the compensating cable 5 can be prevented.
After the mass on the elevator car 1 side and the mass on the counterweight 2 side are unbalanced, the brake is released, the elevator car 1 is moved to a predetermined elevator hall position at a low speed, and passengers are rescued from the elevator car 1.
According to the present embodiment, in the elevator apparatus 100 including the compensating cable 5, the mass on the elevator car 1 side and the mass on the counterweight 2 side can be unbalanced by the emergency rescue device 20 having a simple structure. In the present embodiment, the weight 60 of a desired weight can be suspended on the compensating cable 5 without performing special processing of removing the resin coating of the compensating cable 5 for suspending the weight 60 and providing the locking portion. Thus, by using the emergency rescue tool 20 according to the present embodiment, it is possible to improve the workability during emergency rescue and to reduce the work cost.
Further, according to the present embodiment, the mass on the elevator car 1 side and the mass on the counterweight 2 side can be made unbalanced by the emergency rescue tool 20 having a simple structure, and therefore, passengers can be quickly rescued at the time of emergency stop.
Further, by attaching the emergency rescue tool 20 and the weight 60 to a plurality of locations of the compensating cable 5, it is possible to prevent an excessive load from being applied to a predetermined location of the compensating cable 5, and therefore, it is possible to prevent the compensating cable 5 from being damaged.
In the present embodiment, the weight 60 is suspended from the locking portions 23a and 23b of the emergency rescue tool 20 via the cord 60a and the S-hook 50. Thus, even if the attachment position of the emergency rescue tool 20 gradually approaches the lower portion of the ascending/descending path 6 and becomes a bent portion of the compensating cable 5 when the brake is released, and the emergency rescue tool 20 is inclined, for example, the weight 60 can be rotated via the string-like body 60a and the S-hook 50. Therefore, the weight 60 can be held in a state of being suspended vertically from the respective engaging portions 23a and 23b via the S-hook 50, and the weight 60 can be engaged with the engaging portions 23a and 23b in a stable state.
In the emergency rescue tool 20 of the present embodiment, the first bracket 21a and the second bracket 21b have the same shape, and therefore, the production cost can be reduced. In the emergency rescue tool 20 according to the present embodiment, since the position at which the weight 60 is suspended is symmetrical with respect to the center of the compensating cable 5, the weight 60 can be suspended at a position that is well balanced with respect to the compensating cable 5.
In the emergency rescue tool 20 of the present embodiment, the concave surfaces 24a and 25a of the curved portions 24 and 25 of the first bracket 21a and the second bracket 21b are triangular. Therefore, even if there is a slight difference in the thickness of the compensating cable 5 depending on the elevator apparatus 100, the concave surfaces 24a and 25a can be brought into pressure contact with the periphery of the compensating cable 5, and the emergency rescue tool 20 can be firmly attached to the compensating cable 5 by the degree of fastening of the fastening body 22.
The emergency rescue tool 20 of the present embodiment is not limited to the triangular configuration of the concave surfaces 24a and 25a of the curved portions 24 and 25 of the first bracket 21a and the second bracket 21b, respectively. As long as the shape can be fixed by sandwiching the periphery of the compensation cable 5, a semicircular shape, a semielliptical shape, a quadrangular shape, or another shape may be adopted in accordance with the shape of the compensation cable 5.

In the locking portion 43a, the hook bolts 43a1, 43b1 are screwed into bolt holes provided at both ends of the first bracket 41a in a state protruding enough to suspend the weight 60. The two hook bolts 43a1, 43b1 that constitute the locking portion 43a are arranged on a substantially straight line with the compensation cable 5 interposed therebetween when the first bracket 41a and the second bracket 41b are attached to the compensation cable 5.
In the present embodiment, the emergency rescue tool 40 can be attached to the compensating cable 5 in the same manner as the emergency rescue tool 20 in the first embodiment. In the present embodiment, the locking portions 43a and 43a can hook the cord 60a of the weight 60 to the protruding portions of the hook bolts 43a1 and 54b1, thereby suspending the weight 60 from the emergency rescue tool 40.
In the present embodiment, the two hook bolts 43a1, 43b1 that constitute the locking portions 43a, 43b are arranged on a substantially straight line with the compensating cable 5 in between, and therefore, the load from the weight can be applied to the compensating cable 5 in a well-balanced manner.
When the weight 60 is hung on the protruding locking portions 43a and 43b as in the present embodiment, the string-like body 60a attached to the weight 60 may be directly hooked on the locking portions 43a and 43b, or may be hooked via the S-shaped hook 50 shown in fig. 5.
The emergency rescue tool 40 of the present embodiment also achieves the same effects as those of the first and second embodiments.
Here, in the first to third embodiments, the load is applied to the compensating cable 5 so that one weight 60 is suspended at each of the left and right ends of each emergency rescue device, but the present invention is not limited thereto. For example, two or more weights 60 can be hung on the left and right of each emergency rescue device by providing a hook bolt or a hole near the middle of each first bracket or second bracket in the emergency rescue device and hanging an S-shaped hook. This can reduce the number of emergency rescue devices attached to the compensating cable 5 and the working time, thereby reducing the cost.
Although the first to third embodiments have been described above using an elevator apparatus without a machine room as an example, the present invention can be applied to an elevator apparatus having a machine room above the hoistway 6.
The above-described embodiments are detailed for easy understanding of the present invention, and are not limited to having all of the configurations described. For example, a part of the structure of the above embodiment may be replaced with another structure, and another structure may be added to the structure of the above embodiment. In addition, as for a part of the configuration of the embodiment, addition, deletion, and replacement of other configurations can be performed.
