Next, fig. 11 is a front view showing a diverting sheave beam device of an elevator according to embodiment 2 of the present invention. Fig. 12 is a front view showing a state in the middle of installation of the diverting sheave beam device of fig. 11.
In embodiment 2, the 1 st connecting portion 22 and the 1 st supporting portion 24 are formed of different members. The 2 nd connecting portion 23 and the 2 nd supporting portion 25 are also formed of different members.
The 1 st support portion 24 is coupled to the 1 st link portion 22 so as to be rotatable about a 1 st fulcrum 24 a. Thereby, the 1 st support portion 24 can be displaced relative to the 1 st connecting portion 22 between the 1 st position shown in fig. 11 and the 2 nd position shown in fig. 12.
The 1 st position is a position where the 1 st support portion 24 is caught on the 1 st support beam 16. The 2 nd position is a position where the 1 st support portion 24 projects from the 1 st link 22 to the opposite side of the 2 nd link 23 by a smaller amount than in the 1 st position.
In this example, the 1 st support portion 24 protrudes perpendicularly from the 1 st connecting portion 22 when it is located at the 1 st position. Further, the 1 st support portion 24 does not protrude horizontally from the 1 st connecting portion 22 when it is located at the 2 nd position.
A 1 st support locking member 51 is provided between the 1 st connecting portion 22 and the 1 st support 24. As the 1 st support portion locking member 51, for example, a locking bolt is used.
The 1 st connecting portion 22 is provided with a 1 st through hole 22 a. The 1 st support portion 24 is provided with a 1 st screw hole 24b and a 2 nd screw hole 24 c. The distance from the 1 st fulcrum 24a to the 1 st screw hole 24b is equal to the distance from the 1 st fulcrum 24a to the 2 nd screw hole 24 c.
Further, a straight line connecting the 1 st fulcrum 24a and the 1 st screw hole 24b is perpendicular to a straight line connecting the 1 st fulcrum 24a and the 2 nd screw hole 24 c.
The 1 st support locking member 51 passes through the 1 st through hole 22 a. The 1 st support portion 24 is fixed at the 1 st position by screwing the 1 st support portion locking member 51 into the 1 st screw hole 24 b. Further, by screwing the 1 st support portion locking member 51 into the 2 nd screw hole 24c, the 1 st support portion 24 is fixed at the 2 nd position.
Thus, the 1 st support locking member 51 is selectively screwed into the 1 st or 2 nd threaded hole 24b or 24c, and the 1 st support 24 is restricted from rotating relative to the 1 st joint 22. Further, the 1 st support portion 24 is integrated with the 1 st connecting portion 22 by the 1 st fulcrum 24a and the 1 st support portion locking member 51.
The 2 nd support portion 25 is coupled to the 2 nd link portion 23 so as to be rotatable about the 2 nd fulcrum 25 a. Thereby, the 2 nd support portion 25 can be displaced with respect to the 2 nd connecting portion 23 between the 3 rd position shown in fig. 11 and the 4 th position shown in fig. 12.
The 3 rd position is a position where the 2 nd support part 25 is caught on the 2 nd support beam 17. The 4 th position is a position where the 2 nd support portion 25 projects from the 2 nd link portion 23 to the opposite side of the 1 st link portion 22 by a smaller amount than in the 3 rd position.
In this example, the 2 nd support portion 25 protrudes perpendicularly from the 2 nd connecting portion 22 when it is located at the 3 rd position. When the 2 nd support portion 25 is located at the 4 th position, it does not protrude horizontally from the 2 nd connecting portion 23.
A 2 nd support locking member 52 is provided between the 2 nd connecting portion 23 and the 2 nd support 25. As the 2 nd support portion locking member 52, for example, a locking bolt is used.
The 2 nd connecting portion 23 is provided with a 2 nd through hole 23 a. The 2 nd support portion 25 is provided with a 3 rd screw hole 25b and a 4 th screw hole 25 c. The distance from the 2 nd fulcrum 25a to the 3 rd screw hole 25b is equal to the distance from the 2 nd fulcrum 25a to the 4 th screw hole 25 c.
Further, a straight line connecting the 2 nd fulcrum 25a and the 3 rd screw hole 25b is perpendicular to a straight line connecting the 2 nd fulcrum 25a and the 4 th screw hole 25 c.
The 2 nd support locking member 52 passes through the 2 nd through hole 23 a. The 2 nd bearing portion 25 is fixed at the 3 rd position by screwing the 2 nd bearing portion locking member 52 into the 3 rd screw hole 25 b. Further, by screwing the 2 nd bearing portion locking member 52 into the 4 th screw hole 25c, the 2 nd bearing portion 25 is fixed at the 4 th position.
Thus, the 2 nd support locking member 52 is selectively screwed into the 3 rd or 4 th screw hole 25b or 25c, and the 2 nd support 25 is restricted from rotating relative to the 2 nd connecting portion 23. Further, the 2 nd support portion 25 is integrated with the 1 st connecting portion 23 by the 2 nd fulcrum 25a and the 2 nd support portion locking member 52.
The 1 st support part 24 is provided with a 1 st support part suspending hole 24 d. When the 1 st support part 24 is located at the 2 nd position, the 1 st support part suspending hole 24d is located at a lower end of the 1 st support part 24.
The 2 nd support part 25 is provided with a 2 nd support part suspending hole 25 d. When the 2 nd support part 25 is located at the 4 th position, the 2 nd support part suspending hole 25d is located at a lower end of the 2 nd support part 25. The other structure is the same as embodiment 1.
With such a configuration, the same effects as those of embodiment 1 can be obtained.
Furthermore, the 1 st support portion 24 is displaceable between the 1 st position and the 2 nd position with respect to the 1 st connecting portion 22. Therefore, when the diverting pulley beam device is mounted, interference with the 1 st support beam 16 and the 2 nd support beam 17 can be suppressed without securing a space for rotating the diverting pulley beam device.
Furthermore, the 2 nd support portion 25 is also displaceable between the 3 rd position and the 4 th position with respect to the 2 nd connecting portion 23. Therefore, when the diverting pulley beam device is installed, interference with the 1 st support beam 16 and the 2 nd support beam 17 can be more reliably suppressed.
The 1 st support portion 24 is provided with a 1 st support portion suspending hole 24d, and the 2 nd support portion 25 is provided with a 2 nd support portion suspending hole 25 d. Therefore, the diverting sheave beam device can be lifted by the chain block. Further, it is not necessary to open holes for the chain blocks in the 1 st and 2 nd body rails 26 and 27, which are difficult to handle.
In addition, the 2 nd support portion 25 may not be rotatable with respect to the 2 nd connecting portion 23 as in embodiment 1.
Furthermore, the 1 st support portion 24 may also slide between the 1 st position and the 2 nd position with respect to the 1 st connecting portion 22.
Further, the 2 nd support portion 25 may also slide between the 3 rd position and the 4 th position with respect to the 2 nd connecting portion 23.
Further, as in embodiment 1, the beam device main body 21 of embodiment 2 can be variously modified.
Next, fig. 13 is a front view showing a diverting sheave beam device of an elevator according to embodiment 3 of the present invention. Fig. 14 is a front view showing a state in the middle of installation of the diverting sheave beam device of fig. 13.
In embodiment 3, the 1 st link 22 is coupled to the beam device main body 21 so as to be rotatable about the 1 st fulcrum 22 b. Thereby, the 1 st connecting portion 22 can be displaced relative to the beam device main body 21 between the 1 st position shown in fig. 13 and the 2 nd position shown in fig. 14.
The 1 st position is a position of the 1 st connecting portion 22 when the 1 st supporting portion 24 is attached to the 1 st supporting beam 16. The 2 nd position is a position where the 1 st support portion 24 projects from the beam device main body 21 to the side opposite to the 2 nd connecting portion 23 by a smaller amount than in the 1 st position.
A 1 st link locking member 53 is provided between the beam device main body 21 and the 1 st link 22. As the 1 st connecting part locking member 53, for example, a locking bolt is used.
The beam device main body 21 is provided with a 1 st through hole 21 a. The 1 st connection portion 22 is provided with a 1 st screw hole 22c and a 2 nd screw hole 22 d. The distance from the 1 st fulcrum 22b to the 1 st screw hole 22c is equal to the distance from the 1 st fulcrum 22b to the 2 nd screw hole 22 d.
The 1 st connecting portion locking member 53 passes through the 1 st through hole 21 a. The 1 st connecting part 22 is fixed at the 1 st position by screwing the 1 st connecting part locking member 53 into the 1 st screw hole 22 c. Further, the 1 st connecting part 22 is fixed at the 2 nd position by screwing the 1 st connecting part locking member 53 into the 2 nd screw hole 22 d.
Thus, the 1 st link locking member 53 is selectively screwed into the 1 st screw hole 22c or the 2 nd screw hole 22d, and the 1 st link 22 is restricted from rotating with respect to the beam device main body 21. Further, the 1 st link 22 is integrated with the beam device main body 21 by the 1 st fulcrum 22b and the 1 st link locking member 53.
The 2 nd connecting portion 23 is coupled to the beam device main body 21 so as to be rotatable about the 2 nd fulcrum 23 b. Thereby, the 2 nd connecting portion 23 can be displaced relative to the beam device main body 21 between the 3 rd position shown in fig. 13 and the 4 th position shown in fig. 14.
The 3 rd position is a position of the 2 nd connecting portion 23 when the 2 nd supporting portion 25 is lapped on the 2 nd supporting beam 17. The 4 th position is a position where the 2 nd support portion 25 protrudes from the beam device main body 21 to the side opposite to the 1 st connecting portion 22 by a smaller amount than that at the 3 rd position.
A 2 nd link locking member 54 is provided between the beam device main body 21 and the 2 nd link 23. As the 2 nd connecting part locking member 54, for example, a locking bolt is used.
The beam device main body 21 is provided with a 2 nd through hole 21 b. The 2 nd connection portion 23 is provided with a 3 rd screw hole 23c and a 4 th screw hole 23 d. The distance from the 2 nd fulcrum 23b to the 3 rd screw hole 23c is equal to the distance from the 2 nd fulcrum 23b to the 4 th screw hole 23 d.
The 2 nd connecting part locking member 54 passes through the 2 nd through hole 21 b. The 2 nd connecting part 23 is fixed at the 3 rd position by screwing the 2 nd connecting part locking member 54 into the 3 rd screw hole 23 c. Further, the 2 nd connecting part 23 is fixed at the 4 th position by screwing the 2 nd connecting part locking member 54 into the 4 th screw hole 23 d.
Thus, the 2 nd connecting portion locking member 54 is selectively screwed into the 3 rd screw hole 23c or the 4 th screw hole 23d, and the rotation of the 2 nd connecting portion 23 with respect to the beam device main body 21 is restricted. Further, the 2 nd connecting portion 23 is integrated with the beam device main body 21 by the 2 nd fulcrum 23b and the 2 nd connecting portion locking member 54.
A 1 st connection part suspending hole 22e is provided at a lower end of the 1 st connection part 22. A 2 nd connecting part suspending hole 23e is provided at a lower end of the 2 nd connecting part 23. The other structure is the same as embodiment 1.
With such a configuration, the same effects as those of embodiment 1 can be obtained.
Further, the 1 st connecting portion 22 is displaceable between the 1 st position and the 2 nd position with respect to the beam device main body 21. Therefore, when the diverting pulley beam device is mounted, interference with the 1 st support beam 16 and the 2 nd support beam 17 can be suppressed without securing a space for rotating the diverting pulley beam device.
Further, the 2 nd connecting portion 23 is also displaceable between the 3 rd position and the 4 th position with respect to the beam device main body 21. Therefore, when the diverting pulley beam device is installed, interference with the 1 st support beam 16 and the 2 nd support beam 17 can be more reliably suppressed.
Further, a 1 st connection part suspending hole 22e is provided in the 1 st connection part 22, and a 2 nd connection part suspending hole 23e is provided in the 2 nd connection part 23. Therefore, the diverting sheave beam device can be lifted by the chain block. Further, it is not necessary to open holes for the chain blocks in the 1 st and 2 nd body rails 26 and 27, which are difficult to handle.
Further, the 2 nd connecting part 23 may not be rotatable with respect to the beam device main body 21 as in embodiment 1.
In addition, at least one of the 1 st and 2 nd support portions 24 and 25 may be displaceable as in embodiment 2.
Further, the 1 st connecting portion 22 is slidable between the 1 st position and the 2 nd position with respect to the beam device main body 21.
Further, the 2 nd connecting portion 23 may slide between the 3 rd position and the 4 th position with respect to the beam device main body 21.
Further, as in embodiment 1, the beam device main body 21 of embodiment 3 can be variously modified.
Further, in fig. 1, 4: 1 roping elevator, but the invention can also be applied to other roping methods, such as 2: 1 roping elevator.
The number of the return sheaves supported by the return sheave beam device may be one, or may be three or more.
The diverting pulleys supported by the diverting pulley beam device may also be counterweight diverting pulleys.
