Description

  In the embodiment of the present invention, a cage and a counterweight provided in a hoistway so as to be movable up and down by guide rails are connected in a fishing bottle shape by a rope, and are mutually connected by a hoisting machine around which the rope is wound. The present invention relates to an elevator apparatus that is driven up and down.

  The elevator device is installed in the hoistway provided in the building so that the rider and the counterweight can be raised and lowered by the guide rails, and the rider and the counterweight are connected to the fishing bottle by the rope wound around the hoist. It is configured to be connected in a shape. In such an elevator apparatus, when a building is shaken by an earthquake or a strong wind, a rope that suspends a car or a counterweight may swing greatly. If you run the elevator with the rope swinging in this way, the rope swing will be transmitted to the car, causing the car to roll, giving passengers anxiety, and hindering the car from running. There are things to do.

  The rolling of the car can be reduced to some extent by taking measures such as increasing the spring multiplier of the roller guide provided between the car and the guide rail, or reducing the stroke.

It is a top view explaining the steadying mechanism used for one embodiment of the present invention. It is a front view which shows the structure in the hoistway of the elevator apparatus which concerns on other embodiment of this invention. It is a front view which shows the structure in the hoistway of the elevator apparatus which concerns on further another embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG.1 and FIG.2 is the front view and top view which show the internal structure of the hoistway 11 formed in the building. In these drawings, a guide rail 12 is provided in the hoistway 11, and a car 13 is provided by the guide rail 12 so that it can be raised and lowered. Although not shown in the figure, a counterweight is also provided in the hoistway 11 so that it can be raised and lowered by a guide rail. The car 13 and the counterweight are ropes wound around a hoisting machine (not shown). 14 is connected to the shape of a fishing bottle. That is, a connecting tool 14 a is integrally provided at the tip of the rope 14, and is connected to the upper beam 13 a constituting the outer frame of the car 13 by the connecting tool 14 a. Note that a rope on the counterweight side (not shown) is also connected to the counterweight by a similar connector. The rope 14 is driven in the length direction by a hoisting machine around which the rope 14 is wound, and the car 13 and the counterweight are driven up and down relative to each other.

  The rope 14 is provided with an anti-sway mechanism 15 that engages with the rope 14 and restrains the lateral shake. As shown in FIG. 2, the steady stop mechanism 15 has a pair of beam members 16, and a restraint block 17 that engages with the rope 14 and restrains the lateral shake at the center in the length direction. It is provided integrally. The restraint block 17 is formed in a plate shape from a relatively soft material such as a resin material, and has the same number of through holes 18 as the rope 14. The ropes 14 are inserted and engaged with these through holes 18 one by one, and the lateral deflection of the ropes 14 is restricted.

  In addition, roller guides 19 are provided at both ends in the length direction of the beam member 16, and the entire steadying mechanism 15 including the beam member 16 is attached to the guide rail 12 so as to be movable up and down. That is, as shown in FIG. 2, the roller guide 19 has three rollers 19a, 19b, and 19c, and is attached so as to be able to roll so as to sandwich the guide rail 12 therebetween, and the anti-sway mechanism 15 is supported so as to be movable along the guide rail 12.

  In addition, a guide mechanism similar to the roller guide 19 described above is also provided in a portion of the car 13 that faces the guide rail 12, and supports the car 13 movably along the guide rail 12. Illustration is omitted.

  The lateral movement of the steady rest mechanism 15 is firmly restrained by the guide rails 12 provided on the left and right via the roller guides 19 at both ends. That is, the steady stop mechanism 15 can be moved up and down along the guide rails 12 by the roller guides 19 at both ends, but is firmly fixed by the left and right guide rails 12 in the lateral direction. Therefore, even if the rope 14 engaged with the restraining block 17 touches in the lateral direction, the rope 14 functions to restrain the swing of the rope 14 so that the swing of the rope 14 is not transmitted to the car 13.

  In the embodiment shown in FIG. 1, the steadying mechanism 15 is arranged above the car 13 at a predetermined interval by a support mechanism 21 provided between the car 13 and a rope at this position. 14 is engaged. As described above, the support mechanism 21 fixes the steady stop mechanism 15 in the vertical direction above the car 13 so as to maintain a predetermined distance, but supports the slidably movable mechanism 15 in the lateral direction. In this embodiment, a total of four rods (two are also provided in the depth direction in FIG. 1) which are erected between the upper beam 13 a of the car 13 and the beam member 16 of the steady stop mechanism 15. 21a and ball joints 21b provided at the upper and lower ends thereof, and supports the steadying mechanism 15 so as to be movable in the lateral direction.

  Here, the hole diameter of the through hole 18 through which the rope 14 is inserted is set to be slightly larger than the outer diameter of the rope 14, and the steadying mechanism 15 including the restraining block 17 moves along the length direction of the rope 14. It is configured to be able to. This is to prevent an excessive force from being applied to the ball joint 21b constituting the support mechanism 21 when the rope 14 is stretched as the car 13 is accelerated. That is, the through hole 18 of the restraining block 17 may have any hole diameter that can restrain the movement of the rope 14 in the lateral direction. If the hole diameter is equal to the outer diameter of the rope 14, the through hole 18 of the restraining block 17 is integrally engaged with the rope 14, so that it is difficult to move the rope 14 in the length direction. The rope 14 slightly extends when the car 13 is accelerated. When this extension occurs, if the through hole 18 of the restraining block 17 is integrally engaged with the rope 14 as described above, the support mechanism 21 provided between the steadying mechanism 15 and the riding basket 13 is provided. A force in the extending direction is applied to the ball joint 21b as an unreasonable force to disassemble the ball joint 21b portion. For this reason, it is conceivable that the ball joint 21b is damaged. In order to prevent such a problem, as described above, the hole diameter of the through hole 18 through which the rope 14 is inserted is set slightly larger than the outer diameter of the rope 14, and the steady stop mechanism 15 including the restraining block 17. However, it is comprised so that it can move along the length direction of the rope 14. FIG.

  The support mechanism 21 is not limited to the above structure. For example, although not shown, the upper end of a rod standing on the upper beam 13a of the car 13 is swung through a spring or an elastic material. A structure in which the beam member 16 of the stopping mechanism 15 is in contact with the lower surface may be used.

  In addition, as shown in FIG. 3, a column 21c whose upper end reaches above the steady stop mechanism 15 is erected on the upper beam 13a of the car 13, and a support beam 21d is provided at the upper end thereof. Thus, the steady rest mechanism 15 may be suspended by the wire 21e. Even in such a configuration, the steady rest mechanism 15 is supported in a laterally movable state at a predetermined distance from the upper beam 13 a of the car 13.

  In each of the above-described embodiments, the steadying mechanism 15 is supported by the support mechanism 21 provided between the carriage 13 and the side of the car 13, but the penetrating block 17 provided in the steadying block 15 is provided. The rope 14 may be integrally tightened and fixed in the through hole 18 of the restraining block 17 by making the hole diameter of the hole 18 the same as or slightly smaller than the diameter of the rope 14. With this configuration, even if the support mechanism 21 is not provided between the car 13 and the car 13, the steadying mechanism 15 can be placed laterally with respect to the car 13 with a predetermined distance above the car 13. The directions are fixed so as to be movable relative to each other, and are lifted and lowered together with the car 13.

  In this way, the steady-rest mechanism 15 is engaged with the rope 14 at a position spaced from the car 13 at a predetermined distance in the length direction of the rope 14 and restrains the rope 14 in the lateral direction. Even if the building is shaken by a strong wind or the like, and the rope 14 in the hoistway 11 swings greatly in the lateral direction, the swing of the rope 14 is suppressed near the car 13 by the steady stop mechanism 15 and the guide rail 12. There is no transmission to the car 13. Therefore, it is possible to effectively prevent the car 13 from being shaken by the swing of the rope 14 to hinder the traveling of the car 13 or to give the passenger anxiety.

  In each of the above embodiments, the steadying mechanism 15 is arranged above the car 13 at a predetermined interval, but the steadying mechanism 15 is separated from the car 13 side to You may make it latch to the height direction intermediate part. That is, as shown in FIG. 4, the locking part 22 is attached to the inner wall of the intermediate part in the height direction of the hoistway 11, and the both ends of the steadying mechanism 15 are detachably mounted thereon. In this case, the diameter of the through hole 18 provided in the restraining block 17 of the steady stop mechanism 15 is made larger than the diameter of the rope 14. That is, the movement of the rope 14 in the lateral direction is restricted, but the hole diameter is set so that it can pass freely in the length direction.

  In the above configuration, when the car 13 is located on the lower floor portion in the hoistway 11, the steadying mechanism 15 placed on the locking portion 22 at the intermediate portion in the height direction in the hoistway 11 is Although it is located far above 13 but restrains the intermediate part in the longitudinal direction of the rope 14 in the lateral direction, the rope 14 itself does not shake greatly even if the building shakes, and therefore the car 13 also shakes. Can be deterred. When the car 13 is raised, the distance from the steady-rest mechanism 15 becomes closer as the car 13 is raised, and when the car 13 reaches the intermediate position in the height direction of the hoistway 11, it is installed on the upper surface of the car 13. The upper end of the support 21 thus made contacts the lower surface of the steady rest mechanism 15. When the car 13 further rises in this state, the steady rest mechanism 15 moves away from the locking portion 22 and rises together with a predetermined distance between the car 13. Therefore, when the car 13 is located at a position higher than the intermediate portion in the height direction of the hoistway 11, the steady stop mechanism 15 is always at a position that is kept at a predetermined distance from the car 13 as in the case of FIG. Therefore, it is possible to prevent the swing of the rope 14 from being transmitted to the car 13.

  When the car 13 is lowered, when the car 13 is lowered from the intermediate portion in the height direction of the hoistway 11, the steadying mechanism 15 is again placed on the locking part 22 and separated from the car 13. In this state, as described above, the intermediate portion in the longitudinal direction of the rope 14 is restrained in the lateral direction. Therefore, even if the building shakes, the rope 14 itself does not shake greatly, and the car 13 can be prevented from shaking.

  Although not shown, the steady rest mechanism 15 may be provided in the above-described configuration with respect to the compen- sion rope provided on the lower side of the car 13.

  Further, although not shown, the steady rest mechanism 15 may also be provided with the configuration described above for the rope on the counterweight side. The counterweight does not directly affect the swaying of the car 13. However, when the rope swings, a large bending force is applied between the rope end fitting and the counterweight. It adds a lot of stress. However, since the swinging of the rope is suppressed by providing the steadying mechanism 15, the bending between the connecting tool at the tip of the rope and the counterweight hardly occurs, and this portion can be effectively prevented from being damaged. Can do.

These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
