A detailed description will be given below with reference to the drawings. Overlapping description will be simplified or omitted as appropriate. In each figure, the same reference numeral indicates the same part or the corresponding part.

Embodiment 1.
FIG. 1 is a diagram showing an example of an elevator device. First, the elevator device will be described with reference to FIG. The elevator device includes a basket 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The balance weight 2 moves up and down on the hoistway 3. The basket 1 and the counterweight 2 are suspended from the hoistway 3 by the main rope 4. The balance weight 2 moves in the direction opposite to the direction in which the basket 1 moves. The basket 1 and the balance weight 2 are examples of moving bodies that move on the hoistway 3.

The main rope 4 is wound around the hoisting machine 5. The car 1 is driven by the hoist 5. The hoisting machine 5 is controlled by the control device 6. FIG. 1 shows an example in which the hoisting machine 5 and the control device 6 are installed in the machine room 7 above the hoistway 3. The hoisting machine 5 and the control device 6 may be installed in the hoistway 3. When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be installed at the top of the hoistway 3 or in the pit of the hoistway 3.

FIG. 2 is a diagram showing an example of a balanced weight 2. The balance weight 2 includes a balance weight frame 8 and an adjustment weight 9. The adjusting weight 9 is a weight for adjusting the total weight of the balanced weight 2. The balance weight 2 includes a large number of adjustment weights 9. The adjusting weight 9 is supported by the balanced weight frame 8. The balanced weight frame 8 is a square ring. The balancing weight frame 8 includes an upper frame 10, a lower frame 11, a vertical frame 12, and a vertical frame 13.

In the example shown in FIG. 2, a pair of suspension frame bands 14 are provided on the balance weight 2. The suspension frame band 14 is a reinforcing member provided to prevent the adjustment weight 9 from falling off due to the expansion of the balanced weight frame 8 due to the lateral force received during an earthquake. The suspension frame band 14 can prevent the adjusting weight 9 from coming off the weight frame 8 in the event of an earthquake. The hanging frame band 14 is provided between the vertical frame 12 and the vertical frame 13. When the balance weight 2 is viewed from above, the pair of suspension frame bands 14 are arranged so as to surround the balance weight 2.

The suspension frame band 14 is attached to the balance weight 2 of the elevator device as an earthquake countermeasure for the existing elevator device. However, the existing elevator device is not designed on the assumption that the suspension frame band 14 is attached to the balance weight 2. Therefore, when the suspension frame band 14 is attached to the balance weight 2, the elevator maintenance personnel must determine whether or not the space for attaching the suspension frame band 14 is secured before the attachment. The maintenance staff attaches the suspension frame band 14 to the balance weight 2 only when it can be confirmed that the space is secured.

FIG. 3 is a view of the balanced weight 2 as viewed from above. FIG. 3 shows a counterweight 2 before the suspension frame band 14 is attached. In the example shown in FIG. 3, the counterweight 2 is arranged between the car 1 and the wall 3a forming the hoistway 3 in a plan view.

The maintenance staff confirms that there are no obstacles in the area A shown in FIG. 3 over the range in which the balance weight 2 moves. For example, the distance L1 = 30 mm and the distance L2 = 40 mm. When an obstacle exists in the area A, most of the obstacle exists between the balanced weight 2 and the basket 1 or between the balanced weight 2 and the wall 3a. For example, the equipment and members attached to the car 1 can be obstacles. Equipment and members mounted on the wall 3a can be obstacles. In addition, the wall 3a itself can be an obstacle.

FIG. 4 is a diagram showing an example of the determination device 20 according to the first embodiment. FIG. 5 is a diagram showing a CC cross section of FIG. The maintenance staff performs the above-mentioned determination work using the determination device 20. The determination device 20 includes a main body 21 and a detection body 22.

The main body 21 is removable from the balance weight 2. The adjustment weight 9 of the balance weight 2 is superposed on the lower frame 11. It is difficult to attach the determination device 20 to the stacked adjustment weights 9. Therefore, it is preferable that the main body 21 can be attached to and detached from the balanced weight frame 8. In the example shown in FIGS. 4 and 5, the main body 21 includes a suction portion 23, a main body portion 24, a holding portion 25, and a holding portion 26.

As an example, the suction unit 23 is a magnet that can be attracted to the balanced weight frame 8. The main body 21 may be attached to and detached from the balanced weight frame 8 by means other than suction. The main body 24 is a rod-shaped member having a rectangular cross section. The suction portion 23 is provided on the surface 24a of the main body portion 24. A holding portion 25 and a holding portion 26 are provided on the surface 24b of the main body portion 24. The surface 24b faces in the direction opposite to the direction in which the surface 24a faces. A through hole 25a is formed in the holding portion 25. A through hole 26a is formed in the holding portion 26. The through hole 25a and the through hole 26a are formed so as to be parallel to the longitudinal direction of the main body portion 24. The through hole 25a and the through hole 26a are formed in a straight line.

The detection body 22 is supported by the main body 21 so as to be displaceable with respect to the main body 21. In the example shown in FIGS. 4 and 5, the detector 22 includes a detector 27, a shaft 28, and a shaft 29.

The detection unit 27 has a plate shape. The shaft 28 and the shaft 29 are provided in the detection unit 27. The shaft 28 and the shaft 29 are arranged parallel to the longitudinal direction of the detection unit 27. Further, the shaft 28 and the shaft 29 are arranged in a straight line. The shaft 28 penetrates the through hole 25a. The shaft 29 penetrates the through hole 26a. As a result, the detection body 22 is rotatably supported with respect to the main body 21.

If no external force acts on the detection body 22, the detection body 22 does not displace with respect to the main body 21. When an external force acts on the detection body 22 from a specific direction, the detection body 22 is displaced with respect to the main body 21. 4 and 5 show an example in which the above function is realized by fitting the shaft 28 and the through hole 25a and fitting the shaft 29 and the through hole 26a. As another example, the holding portion 25 may be provided with a mechanism for adjusting the force for holding the shaft 28. The holding portion 26 may be provided with a mechanism for adjusting the force for holding the shaft 29.

Next, the determination work using the determination device 20 will be described in detail. FIG. 6 is a flowchart showing an example of a determination operation using the determination device 20. The elevator maintenance staff first attaches the determination device 20 to the balance weight 2 (S101). In S101, the maintenance person first takes the determination device 20 and rides on the car 1. The maintenance personnel then move the car 1 to a specific intermediate height. The intermediate height is a height at which a maintenance worker can balance the determination device 20 from above the car 1 and attach it to the weight 2. When the maintenance staff stops the car 1 at the intermediate height, the maintenance staff attaches the determination device 20 to the balance weight 2.

FIG. 7 is a plan view showing an example of the determination device 20 attached to the balance weight 2. FIG. 8 is a view of the determination device 20 attached to the balance weight 2 as viewed from the direction D shown in FIG. 7. 7 and 8 show an example in which the determination device 20 is attached to the surface 10a of the upper frame 10. For example, the surface 10a faces the wall 3a.

In the example shown in FIGS. 7 and 8, the suction unit 23 is attracted to the surface 10a of the upper frame 10 so that the determination device 20 is fixed to the weight frame 8 in a balanced manner. In S101, the maintenance staff arranges the determination device 20 so that the tip of the detection unit 27 coincides with the boundary of the region A. That is, the maintenance staff arranges the determination device 20 so that the distance from the weight 2 in which the determination device 20 protrudes in the horizontal direction is the distance L1 in the plan view. The width W of the detection unit 27 preferably matches the width of the region A. However, the width W does not have to completely match the width of the region A as shown in FIG.

As shown in FIGS. 7 and 8, the detection body 22 is held at the detection position by the main body 21 in a state where the main body 21 is fixed to the balanced weight 2. The detection position is a position for detecting an obstacle existing in the area A. The detector 22 held at the detection position extends horizontally from the main body 21. Specifically, the detector 22 is arranged horizontally.

Next, the maintenance staff reciprocates the car 1 using an operation terminal (not shown) provided on the car 1 (S102). For example, when the maintenance staff attaches the determination device 20 to the counterweight 2 as shown in FIGS. 7 and 8, the car 1 is moved upward and the car 1 is stopped at the landing on the top floor. As a result, the balance weight 2 moves downward and stops at the lowest position of the movable range. Next, the maintenance staff moves the car 1 downward and stops the car 1 at the landing on the lowest floor. As a result, the balance weight 2 moves upward and stops at the uppermost position of the movable range. Next, the maintenance staff moves the car 1 upward and restarts the car 1 at the above intermediate height.

When the car 1 is stopped again at the intermediate height in S102, the maintenance staff confirms whether or not the detector 22 is displaced from the detection position (S103). 9 and 10 are diagrams for explaining the function of the determination device 20. 9 and 10 correspond to a view of the determination device 20 attached to the balance weight 2 as viewed from the direction D shown in FIG. 7.

FIG. 9 shows an example in which the balance weight 2 is moving upward. FIG. 9 shows an example in which a part of the obstacle 15 provided on the wall 3a exists in the region A in a plan view. In such a case, the balance weight 2 moves upward, so that the detector 22 of the determination device 20 collides with the obstacle 15 from below. The detection body 22 is held at the detection position by the main body 21 until immediately before the collision with the obstacle 15. When the detection body 22 receives a force from above while being held at the detection position, the detection body 22 rotates about the shaft 28 and the shaft 29 and is displaced downward. The detection body 22 is held by the main body 21 in a position after displacement, that is, in a state where the tip portion is lower than the detection position.

FIG. 10 shows an example in which the balance weight 2 is moving downward. Similar to FIG. 9, FIG. 10 also shows an example in which a part of the obstacle 15 exists in the region A in a plan view. In such a case, the balance weight 2 moves downward, so that the detector 22 of the determination device 20 collides with the obstacle 15 from above. The detection body 22 is held at the detection position by the main body 21 until immediately before the collision with the obstacle 15. When the detection body 22 receives a force from below while being held at the detection position, the detection body 22 rotates about the shaft 28 and the shaft 29 and is displaced upward. The detection body 22 is held by the main body 21 in a position after displacement, that is, in a state where the tip portion is raised above the detection position.

9 and 10 are examples in which the determination device 20 is attached to the surface 10a of the upper frame 10, but in reality, the determination device 20 is also attached to the surface 10b of the upper frame 10. The surface 10b is a surface facing in the direction opposite to the direction in which the surface 10a faces. That is, the surface 10b faces the direction of the car 1 in a plan view.

In this way, if the obstacle 15 comes into contact with the detection body 22 while the balance weight 2 is reciprocating in S102, the detection body 22 is displaced from the detection position. If the detector 22 remains in the detection position when the car 1 is restarted at the intermediate height, the maintenance personnel determines No in S103. In such a case, the maintenance staff determines that the space for attaching the suspension frame band 14 is secured. When the maintenance staff determines No in S103, the determination device 20 is removed from the balance weight 2, and then the suspension frame band 14 is attached to the balance weight 2 (S104).

On the other hand, if the detection body 22 is displaced from the detection position when the car 1 is stopped again at the intermediate height, the maintenance staff determines Yes in S103. In such a case, the maintenance staff determines that the space for attaching the suspension frame band 14 is not secured.

In the example shown in the present embodiment, whether or not a space for attaching the suspension frame band 14 is secured to the balance weight 2 only by confirming the position of the detector 22 after moving the balance weight 2. Can be determined. That is, by using the determination device 20, the above determination can be easily performed. Further, the determination device 20 does not use paint or the like unlike the conventional device. Therefore, it is easy to handle.

In the example shown in FIG. 6, the car 1 is reciprocated in S102, which is an example. For example, if the determination device 20 can be attached at the pit of the hoistway 3 and the determination device 20 can be removed at the top of the hoistway 3, the car 1 is moved from the landing on the top floor to the lowest floor in S102. You may move it in one direction to the landing.

Hereinafter, another example in which the determination device 20 can be adopted will be described. If possible, the determination device 20 may be adopted by combining a plurality of examples shown below.

FIG. 11 is a diagram showing another example of the determination device 20. FIG. 11 is a diagram corresponding to FIG. In the example shown in FIG. 11, the determination device 20 includes a main body 21 and a detection body 22. The main body 21 includes a suction portion 23, a main body portion 24, a positioning portion 30, a holding portion 25, and a holding portion 26. The detection body 22 includes a detection unit 27, a shaft 28, and a shaft 29.

In the example shown in FIG. 11, the suction portion 23 provided on the main body portion 24 sucks on the upper surface 10c of the upper frame 10. That is, in the example shown in FIG. 11, the main body 21 is removable from the upper surface of the balanced weight frame 8. The positioning unit 30 is provided on the main body unit 24. The positioning portion 30 extends downward from the main body portion 24 in a state where the suction portion 23 is attracted to the upper surface 10c. The positioning unit 30 is a member for positioning the detection body 22 by facing the surface 10a or the surface 10b of the upper frame 10. For example, the detection body 22 is arranged at the detection position by bringing the positioning unit 30 into contact with the surface 10a while the suction unit 23 is adsorbed on the upper surface 10c.

The holding portion 25 and the holding portion 26 are provided on the main body portion 24. The holding portion 25 and the holding portion 26 may be provided in the positioning portion 30. The holding portion 25, the holding portion 26, and the detector 22 are the same as the examples shown in FIGS. 4 and 5. The detection body 22 is rotatably supported by the main body 21 via a shaft 28 and a shaft 29 extending in the horizontal direction while the main body 21 is fixed to the upper surface 10c of the upper frame 10. Further, as in the example shown in FIGS. 9 and 10, when the detection body 22 receives a force from above or below while being held at the detection position, the detection body 22 is displaced according to the direction in which the force is received, and after the displacement, the detection body 22 is displaced. It is held in the main body 21 at the position.

FIG. 12 is a diagram showing another example of the determination device 20. FIG. 12 is a diagram corresponding to FIG. 7. In the example shown in FIG. 12, the determination device 20 includes a main body 21 and a detection body 22. The main body 21 includes a suction portion 23, a main body portion 24, a positioning portion 30, a holding portion 25, and a holding portion 26. The detection body 22 includes a detection unit 27, a shaft 28, and a shaft 29.

In the example shown in FIG. 12, the suction portion 23 provided on the main body portion 24 sucks on the surface 13a of the vertical frame 13. The surface 13a faces the guide rail 16 for guiding the movement of the balance weight 2. That is, in the example shown in FIG. 12, the main body 21 is removable from the side surface of the balanced weight frame 8.

The positioning unit 30 is provided on the main body unit 24. The positioning portion 30 extends laterally from the main body portion 24 in a state where the suction portion 23 is attracted to the surface 13a. The positioning unit 30 is a member for positioning the detection body 22 by facing the surface 13b of the surface of the vertical frame 13 facing the wall 3a side or the surface facing the car 1 side in a plan view. For example, the detection body 22 is arranged at the detection position by bringing the positioning unit 30 into contact with the surface 13b while the suction unit 23 is adsorbed on the surface 13a.

The holding portion 25 and the holding portion 26 are provided in the positioning portion 30. The holding portion 25, the holding portion 26, and the detector 22 are the same as the examples shown in FIGS. 4 and 5. The detection body 22 is rotatably supported by the main body 21 via a shaft 28 and a shaft 29 extending in the horizontal direction while the main body 21 is fixed to the surface 13a of the vertical frame 13. Further, as in the example shown in FIGS. 9 and 10, when the detection body 22 receives a force from above or below while being held at the detection position, the detection body 22 is displaced according to the direction in which the force is received, and after the displacement, the detection body 22 is displaced. It is held in the main body 21 at the position.

FIG. 13 is a diagram showing another example of the determination device 20. FIG. 13 is a diagram corresponding to FIG. 4. In the example shown in FIG. 13, the determination device 20 includes a main body 21 and a detection body 22. The main body 21 is the same as the example shown in FIGS. 4 and 5. The main body 21 may be similar to the example shown in FIG. The main body 21 may be similar to the example shown in FIG.

The example shown in FIG. 13 differs from the above-mentioned examples in that the detection body 22 can be expanded and contracted. The detector 22 includes a support 31, a detector 27, a shaft 28, a shaft 29, and a bolt 32.

The support portion 31 has a plate shape. The shaft 28 and the shaft 29 are provided on the support portion 31. The shaft 28 and the shaft 29 are arranged parallel to the longitudinal direction of the support portion 31. Further, the shaft 28 and the shaft 29 are arranged in a straight line. The shaft 28 penetrates the through hole 25a. The shaft 29 penetrates the through hole 26a. As a result, the support portion 31 is rotatably supported with respect to the main body 21.

The detection unit 27 has a plate shape. The detection unit 27 is provided on the support unit 31 so that the distance at which the detection body 22 protrudes horizontally from the main body 21 is variable while the main body 21 is balanced and fixed to the weight 2. For example, the detection unit 27 is arranged so as to overlap the support unit 31. Further, the detection unit 27 is formed with an elongated hole 27a having a length perpendicular to the axis 28 and the axis 29. The bolt 32 penetrates the elongated hole 27a and is screwed into a screw hole (not shown) formed in the support portion 31. When the bolt 32 is loosened, the detection unit 27 can be moved with respect to the support unit 31 in the direction indicated by the arrow E in FIG. By tightening the bolt 32, the detection portion 27 is fixed to the support portion 31.

For example, consider a case where two types of suspension frame bands 14 are prepared, and if there are no obstacles in both the A region and the B region shown in FIG. 3, the suspension frame band 14 can be balanced and attached to the weight 2. For example, L3 = 40 mm. In such a case, the maintenance staff performs the above-mentioned determination work using the determination device 20 shown in FIG. At this time, the maintenance staff arranges the determination device 20 so that the tip of the detection unit 27 coincides with the boundary of the region B (L3 = 40 mm). Then, if the maintenance staff can determine No in S103, the maintenance staff attaches the high-strength suspension frame band 14 to the weight 2 in S104.

On the other hand, when the maintenance staff determines Yes in S103, the maintenance staff rearranges the determination device 20 so that the tip of the detection unit 27 coincides with the boundary of the region A (L1 = 30 mm), and repeats the above determination operation. Then, if the maintenance staff can determine No in S103, the maintenance staff attaches the normal suspension frame band 14 to the weight 2 in S104.

FIG. 14 is a diagram showing another example of the determination device 20. FIG. 15 is a view of the determination device 20 as viewed from the F direction shown in FIG. FIG. 14 is a diagram corresponding to FIG. FIG. 15 is a diagram corresponding to FIG. In the example shown in FIGS. 14 and 15, the determination device 20 includes a main body 21, a detection body 22, and a coupling body 33.

The main body 21 is removable from the balance weight 2. It is preferable that the main body 21 is removable from the balanced weight frame 8. In the example shown in FIGS. 14 and 15, the main body 21 includes a suction portion 23, a main body portion 24, a holding portion 34, and a holding portion 35.

As an example, the suction unit 23 is a magnet that can be attracted to the balanced weight frame 8. The main body 21 may be attached to and detached from the balanced weight frame 8 by means other than suction. The main body 24 is a rod-shaped member having a rectangular cross section. The suction portion 23 is provided on the surface 24a of the main body portion 24. A holding portion 34 and a holding portion 35 are provided on the surface 24b of the main body portion 24.

The detector 22 is supported by the main body 21. In the example shown in FIGS. 14 and 15, the detector 22 has a plate shape. The detection body 22 is supported by the main body 21 by sandwiching one edge portion 22a between the holding portion 34 and the holding portion 35. The detection body 22 supported by the main body 21 extends from the edge portion 22a in the direction in which the surface 24b faces.

If no external force acts on the detection body 22, the detection body 22 maintains the state of being held by the main body 21. On the other hand, when an external force acts on the detection body 22 from a specific direction, the detection body 22 is separated from the main body 21. That is, the force that the holding unit 34 and the holding unit 35 sandwich the detection body 22 is preset so that the detection body 22 is released from the main body 21 when an external force acts on the detection body 22 from a specific direction.

The connecting body 33 connects the main body 21 and the detecting body 22. The connecting body 33 prevents the detecting body 22 from falling when the detecting body 22 comes off from the main body 21.

Also in the examples shown in FIGS. 14 and 15, the detection body 22 is held at the detection position by the main body 21 in a state where the main body 21 is balanced and fixed to the weight 2. The detector 22 held at the detection position extends horizontally from the main body 21. Specifically, the detector 22 is arranged horizontally. Then, when the detection body 22 receives a force from above while being held at the detection position, the detection body 22 is disengaged from the main body 21 as shown in FIG. Similarly, when the detection body 22 receives a force from below while being held at the detection position, the detection body 22 is disengaged from the main body 21 as shown in FIG. The detection body 22 detached from the main body 21 is held in a suspended state on the connecting body 33.

When the determination device 20 shown in FIGS. 14 and 15 is used, the maintenance staff determines in S103 whether or not the detector 22 is detached from the main body 21. If the detector 22 is still held by the main body 21, the maintenance staff determines No in S103. If the detector 22 is detached from the main body 21, the maintenance staff determines Yes in S103.

In each of the above examples, the maintenance staff brings the determination device 20 to the site every time the determination work is performed. Therefore, it is desirable that the determination device 20 is easy to carry. For example, in the example shown in FIG. 4, the detection unit 27 may be a separable type, a telescopic type, or a foldable type, and a main body portion 24 and a suction portion 23 may be provided for each of the holding portion 25 and the holding portion 26.

Further, in the present embodiment, an example in which the determination device 20 is attached to the balance weight 2 has been described. This is just an example. When the device or member is mounted on the car 1, it may be determined whether or not the mounting space is secured by using the same device as the determining device 20.
