Abstract

<P>PROBLEM TO BE SOLVED: To provide a balance rope device for an elevator, easily suppressing the lowering of a balancing wheel due to the secular elongation of a balance rope. <P>SOLUTION: The balance rope 6 is thrust at a position upper than the balancing wheel 8 by the thrust of a thrusting means 12. When the balancing wheel 8 is lowered due to the secular elongation of the balance rope 6 beyond a predetermined position from a bottom face 10 of an elevator shaft 1, a supporting frame 11 is supported by an elastic support 16. At this time, the balance rope 6 having reduced tension is thrust by a thrusting wheel 14 of the thrusting means 12 to give bending to a suspended wire and prevent the deviation due to looseness. Thus, the excess lowering of the balancing wheel 8 due to the secular elongation of the balance rope 6 is prevented, the frequency of heading the balance rope 6 as countermeasures for the excess lowering of the balancing wheel 8 is reduced and the balancing wheel 8 is held at the predetermined position with less work, resulting in saving maintenance cost. <P>COPYRIGHT: (C)2003,JPO

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator for compensating for a difference between a car side weight and a counterweight side weight of a main rope related to an elevator position of a car in a traction type elevator. The present invention relates to an unbalanced rope device. 2. Description of the Related Art FIG. 4 is a perspective view schematically showing a conventional elevator apparatus, and FIG. 4 is a perspective view conceptually showing the elevator apparatus. In the figure, 1 is a hoistway of an elevator, 2 is a hoist installed in a machine room provided above the hoistway 1, and 3 is a main rope, which is wound around the hoist 2 and A basket 4 is suspended at one end and a counterweight 5 is attached to the other end.
Are connected. Reference numeral 6 denotes a balancing rope, one end of which is connected to the car 4 and the other end of which is connected to the balancing weight 5. The hanging rope 6 is suspended from the hoistway 1 by forming a hanging curved portion 7. Numeral 8 denotes a balancing vehicle, which is arranged in a state of straddling the hanging curve 7 of the balancing rope 6 to apply tension to the balancing rope 6. Reference numeral 9 denotes a guide mechanism comprising a rail erected on the bottom surface 10 of the hoistway 1. Reference numeral 11 denotes a support frame pivotally supporting the lifting vehicle 8, which is engaged with the guide mechanism 9 and held so as to be able to move in the vertical direction. It is located at the bottom of road 1. [0004] A conventional elevator balancing rope device is a traction-type elevator constructed as described above. In the traction type elevator, the weight of the car 4 generated by the weight of the main rope 3 and the weight of the balancing weight 5 are generated in relation to the vertical position of the car 4. The difference from the weight is compensated by the weight of the balancing rope 6. The suspension wheel 8 is engaged with the guide mechanism 9 via the support frame 11 and is held so as to be movable in the vertical direction. Thus, by applying tension to the balancing rope 6, unnecessary swinging of the balancing rope 6 is prevented. [0005] In the above-described conventional rope binding device for an elevator, the position of the vehicle 8 is lowered because the main rope 3 and the rope 6 are aged. Then, the lowering of the lifting vehicle 8 continues, and the position of the lifting vehicle 8 from the bottom surface 10 of the hoistway 1 becomes lower than a predetermined position. In this case, an adjustment operation of trimming the hanging rope 6 and the like and arranging the lifting wheel 8 above a predetermined position is performed. This adjustment work has a problem that, since an elongation amount of the hanging rope 6 and the like is unexpectedly large in an elevator having a long ascending and descending stroke, a high frequency of trimming adjustment work is required, and a troublesome work is required. . SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a balancing rope device for an elevator which can reduce a descent of a balancing vehicle due to aging of a balancing rope or the like. Aim. [0007] In the lifting rope device of the elevator according to the present invention, it is connected to one end of a main rope which is wound around a hoist of the elevator and suspended from a hoistway. A balancing weight connected to the other end of the car and the main rope, one end connected to the car and the other end connected to the balancing weight, forming a hanging curved portion and hanging from the hoistway;
A suspension vehicle that is arranged in a state of being laid over the hanging curve portion of the suspension rope to apply tension to the suspension rope, and that the suspension vehicle is pivotally mounted and disposed at the bottom of the hoistway so that it can move vertically. A support frame that is held by the hoistway, an elastic support that stands upright from the bottom surface of the hoistway and elastically supports the support frame that has fallen excessively, and is displaceably mounted on the support frame and is balanced at a position higher than the suspension vehicle. A pressing wheel for pressing the rope is provided, and pressing means for bending the suspension line of the hanging rope by the pressing wheel when the support frame is supported by the elastic support is provided. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIG. 1 is a diagram showing an example of an embodiment of the present invention, and is a perspective view of a bottom portion of an elevator shaft. In addition, other than FIG. 1, the elevator is comprised like FIG. 4 mentioned above. In the figure, 1 is a hoistway of an elevator, 6 is a balancing rope, one end of which is connected to the car 4 in FIG. 4 described above and the other end is connected to a balancing weight 5 to form a hanging curved portion 7 and hang on the hoistway 1. Have been. Reference numeral 8 denotes a balancing vehicle, which is arranged in a state of straddling the hanging curve 7 of the balancing rope 6 to apply tension to the balancing rope 6. Reference numeral 9 denotes a guide mechanism comprising a rail erected on the bottom surface 10 of the hoistway 1. Reference numeral 11 denotes a support frame pivotally supporting the lifting vehicle 8, which is engaged with the guide mechanism 9 and held so as to be able to move in the vertical direction. It is located at the bottom of road 1. Reference numeral 12 denotes a pressing means, which is a rail 13 fixed to the support frame 11 and disposed horizontally, a pressing wheel 14 engaged with the rail 13 and held movably in the longitudinal direction of the rail 13, and both ends. Support frame 11 and pressing wheel 1 respectively
It is constituted by a compression coil spring 15 connected to the shaft 4. Reference numeral 16 denotes an elastic support made of a compression coil spring. The elastic support 16 stands upright from the bottom surface 10 of the hoistway 1 so as to face the support frame 11, and elastically supports the support frame 11 which is excessively lowered. In the lift rope device of the elevator constructed as described above, the difference between the weight of the car 4 side and the weight of the balance weight 5 due to the weight of the main rope 3 related to the position of the car 4 in the traction type elevator. Is compensated by the weight of the balancing rope 6. The suspension wheel 8 is engaged with the guide mechanism 9 via the support frame 11 and is held so as to be movable in the vertical direction.

It is pressed at a position higher than the balance wheel 8. Then, due to the aging of the main rope 3 and the hanging rope 6 of the elevator, the position of the hanging car 8 is lowered. When the lowering of the lifting vehicle 8 from the bottom surface 10 of the hoistway 1 is continued below the lowering of the lifting vehicle 8, the support frame 11 is supported by the elastic support 16. Since the support frame 11 is supported by the elastic support 16, the tension of the hanging rope 6 is reduced, so that the pressing wheel 14 is displaced by the pressing force of the pressing means 12, and the hanging of the hanging rope 6 is prevented. The wiring is bent as shown in FIG. Thereby, the slack of the balancing rope 6 caused by the support frame 11 being supported by the elastic support 16 is prevented, and the deviation of the balancing rope 6 from the balancing wheel 8 is prevented. In this way, it is possible to prevent a problem that occurs when the position of the balancing vehicle 8 is lowered from a predetermined position, that is, excessively lowered due to the aging of the balancing rope 6 or the like. Therefore, as a countermeasure against excessive lowering of the lifting vehicle 8, the frequency of the adjustment work of cutting the lifting rope 6 or the like and disposing the lifting vehicle 8 above a predetermined position can be reduced. Therefore, the lifting vehicle 8 can be easily held at a predetermined position where no trouble occurs by a small amount of work against the aging of the lifting rope 6, etc., and the maintenance cost of the lifting rope device can be reduced. . Embodiment 2 FIG. 2 is a view showing an example of another embodiment of the present invention, and is a perspective view of a bottom portion of an elevator shaft. Except for FIG. 2, an elevator is configured similarly to FIG. 4 described above. In the figure, FIG.
The same reference numerals denote the corresponding parts, and 17 denotes a pressing means, one end of which is a pivot arm 18 pivotally supported by the support frame 11, and the pivot arm 18 pivotally supported by the pivot end of the pivot arm 18. The push wheel 14 is disposed at a position higher than the end, and a tension coil spring 19 whose both ends are connected to the turning end of the turning arm 18 and the shaft of the pushing wheel 14, respectively. Also in the lifting rope device of the elevator constructed as described above, the difference between the weight of the car 4 side and the weight of the balancing weight 5 due to the weight of the main rope 3 related to the position of the car 4 in the traction type elevator. Is compensated by the weight of the balancing rope 6. The suspension wheel 8 is engaged with the guide mechanism 9 via the support frame 11 and is held so as to be movable in the vertical direction. Thereby, tension is applied to the balancing rope 6, and unnecessary swinging of the balancing rope 6 is prevented. The tension coil spring 1 of the pressing means 17
The suspending rope 6 is pressed at a position above the suspending wheel 8 by the pulling force 9 through the pushing wheel 14. When the main rope 3 and the hanging rope 6 of the elevator grow over time and the position of the hanging vehicle 8 becomes lower than a predetermined position, the support frame 11 is supported by the elastic support 16. When the support frame 11 is supported by the elastic support 16 and the tension of the hanging rope 6 is reduced, the suspension line of the hanging rope 6 is bent by the pressing force of the pressing means 17 as shown in FIG. I do. Therefore, although detailed description is omitted, the same operation as the embodiment of FIG. 1 can be obtained in the embodiment of FIG. Embodiment 3 FIG. 3 also shows an example of another embodiment of the present invention, and is a perspective view of a bottom portion of an elevator shaft. In addition, other than FIG. 3, an elevator is comprised like FIG. 4 mentioned above. In the figure, FIG.

Reference numeral 20 denotes a pressing means, one end of which is pivoted by the pivoting arm 21 pivotally supported by the support frame 11 and the pivoting end of the pivoting arm 21. It is constituted by a pressing wheel 14 arranged at a position above the end. In the lift rope device of the elevator constructed as described above, the difference between the weight of the car 4 on the side of the car 4 and the weight of the balance weight 5 on the basis of the weight of the main rope 3 related to the position of the car 4 in the traction type elevator. Is compensated by the weight of the balancing rope 6. The suspension wheel 8 is engaged with the guide mechanism 9 via the support frame 11 and is held so as to be movable in the vertical direction. Thereby, tension is applied to the balancing rope 6, and unnecessary swinging of the balancing rope 6 is prevented. Further, the suspension rope 6 is pressed at a position higher than the suspension wheel 8 via the pressing wheel 14 by the weight of the rotating arm 21 of the pressing means 20. Then, when the main rope 3 and the hanging rope 6 of the elevator grow over time and the position of the hanging vehicle 8 becomes lower than a predetermined position, the support frame 11 is supported by the elastic support 16. When the support frame 11 is supported by the elastic support 16 and the tension of the hanging rope 6 is reduced, the suspension line of the hanging rope 6 is bent by the pressing force of the pressing means 20 as shown in FIG. I do. Therefore, although detailed description is omitted, the same operation as the embodiment of FIG. 1 can be obtained in the embodiment of FIG. As described above, the present invention is connected to a car connected to one end of a main rope hung on a hoisting machine of an elevator and suspended from a hoistway, and connected to the other end of the main rope. A suspended weight, one end of which is connected to the car and the other end of which is connected to the suspended weight, forms a hanging curve portion and is suspended on the hoistway, and a state of being laid over the hanging curve portion of the hanging rope.

Rope is balanced by a pressing wheel when is supported by an elastic support And a pressing means for bending the suspension line. With this arrangement, the difference between the car side weight and the counterweight side weight due to the weight of the main rope related to the elevator position of the elevator car is compensated for by the own weight of the balancing rope, and the balancing rope is used for the balancing rope. The tension is applied to prevent unnecessary swinging of the balancing rope. Also, the suspension rope is pressed at a position above the suspension wheel by the pressing force of the pressing means. Then, when the hang-up ropes and the like grow over time, the hang-up vehicle position is lowered, and when the position of the hang-up vehicle from the bottom of the hoistway becomes lower than a predetermined position, the support frame is supported by the elastic support. As a result, the tension of the hanging rope is reduced, so that the hanging rope is pressed by the pressing means, and the suspension line is bent. by this,
When the support frame is supported by the elastic support, loosening of the balancing rope is prevented, and deviation of the balancing rope from the balancing vehicle is prevented. In this way, it is possible to prevent a problem that occurs when the position of the balancing vehicle due to aging of the balancing rope or the like falls below the predetermined position excessively. In addition, as a countermeasure against excessive lowering of the balance vehicle, the frequency of the adjustment work of arranging the balance vehicle above a predetermined position by cutting the balance rope or the like can be reduced. Therefore, it is possible to easily maintain the suspension vehicle at a predetermined position where no trouble occurs by performing a small operation of the suspension vehicle with respect to the aging of the suspension rope and the like, and there is an effect of reducing the maintenance cost of the suspension rope device.
