Fig. 4 is a flowchart of an elevator installation method according to embodiment 1 of the present invention. An elevator installation method according to embodiment 1 of the present invention is an elevator installation method including steps 1 to 8 shown as S1 to S8 in fig. 4.
Fig. 5 is a schematic view showing a step 1 (S1 in fig. 4) of the elevator installation method as viewed in the direction of the arrow denoted by C-C in fig. 3. Before the step 1, the support beam 6 and the scaffold 51 are attached to the upper portion of the hoistway 1, and the chain block 52 is attached to the hoistway ceiling 1 a. The scaffold 51 is provided in a horizontal projection plane of the car 2 shown in fig. 3 so as not to hinder lifting when lifting the constituent devices of the elevator to the upper part of the hoistway 1.
In the step 1, the car return sheave 8 and the counterweight return sheave 9 are suspended by the chain block 52, and the car return sheave 8 and the counterweight return sheave 9 are mounted on the upper surface of the support beam 6 as shown in fig. 1 to 3.
Fig. 6 is a schematic view showing a 2 nd step (S2 in fig. 4) of the elevator mounting method as viewed in the direction of the arrow denoted by C-C in fig. 3. Further, the 2 nd step of embodiment 1 of the present invention corresponds to the winding step of claim 1.
In step 2, the main ropes 12 are wound around the pulleys in the order of the counterweight end 12b side to the car end 12a side of the main ropes 12, the hoisting machine 7, and the car return sheave 8, and the portions of the main ropes 12 closer to the counterweight end 12b side than the hoisting machine 7 are fixed to the support beam 6.

The rope fixing members 54 temporarily fix the main ropes 12 to the support beam 6 at the counterweight end 12b side of the hoisting machine 7. The rope fixture 54 can be easily attached to and detached from the support beam 6 and the main rope 12, and the rope fixture 54 holds the main rope 12 in a sandwiched manner to fix the main rope 12 to the support beam 6. The support beam 6 in embodiment 1 of the present invention corresponds to the support body according to claim 1.
Fig. 7 is a schematic view showing a 3 rd step (S3 in fig. 4) of the elevator mounting method as viewed in the direction of the arrow denoted by C-C in fig. 3. Further, step 3 of embodiment 1 of the present invention corresponds to the hoisting machine hoisting step of claim 1.
In the 3 rd step, the hoisting machine 7 is hoisted by pulling the portion of the main ropes 12 on the car end 12a side of the car return sheave 8. The 3 rd step is performed as follows.
A winch 53 is provided below the car return sheave 8, and a portion of the main rope 12 on the car end 12a side of the car return sheave 8 is connected to the winch 53 by a traction rope 53 a. The pull-in rope 53a is a rope that is thinner, lighter, and more flexible than the main rope 12, and the pull-in rope 53a can be wound by the winch 53.
By winding the traction rope 53a with the winch 53, the portion of the main rope 12 on the car end 12a side of the car return sheave 8 is pulled downward. Since the portions of the main ropes 12 on the counterweight end 12b side of the hoisting machine 7 are fixed to the support beam 6 by the rope fixtures 54, the portions of the main ropes 12 on the rope fixtures 54 side of the car return sheave 8 move to the car end 12a side, and the length between the car return sheave 8 and the rope fixtures 54 of the main ropes 12 is shortened, so that the hoisting machine 7 is hoisted. Thereby, the hoisting machine 7 is lifted up to the lower surface of the support beam 6.
Fig. 8 is a schematic view showing a 4 th step (S4 in fig. 4) of the elevator mounting method as viewed in the direction of the arrow denoted by C-C in fig. 3.
In the 4 th step, as shown in fig. 1 to 3, the hoisting machine 7 is attached to the lower surface of the support beam 6. Further, the rope holder 54 is detached from the main rope 12 and the support beam 6, and the traction rope 53a is detached from the main rope 12.
Fig. 9 is a schematic view showing a step 5 (S5 in fig. 4) of the elevator mounting method as viewed in the direction of the arrow denoted by C-C in fig. 3. The 5 th step in embodiment 1 of the present invention corresponds to the winding step in claim 2.
In the 5 th step, the main ropes 12 are wound around the respective sheaves in the order of the counterweight suspending sheave 11 and the counterweight return sheave 9 from the counterweight end 12b side to the car end 12a side of the main ropes 12, and the portions of the main ropes 12 on the counterweight end 12b side of the counterweight suspending sheave 11 are fixed to the support beam 6 above the counterweight suspending sheave 11. The suspending sheave 11 for the counterweight according to embodiment 1 of the present invention corresponds to the suspending sheave according to claim 2, and the counterweight 3 according to embodiment 1 of the present invention corresponds to the vertically movable body according to claim 2. The 5 th step is performed as follows.
The counterweight 3 on which the counterweight suspending wheel 11 is mounted is placed at a position below the upper end of the counterweight elevating area.
In the 3 rd step, the main ropes 12 are wound around the counterweight return sheave 9. In the 5 th step, the portion of the main rope 12 on the counterweight end 12b side of the counterweight return sheave 9 is wound around the pulley of the counterweight suspending sheave 11, the counterweight end 12b of the main rope 12 is lifted up to the upper portion of the hoistway 1 by the chain block 52, the counterweight end 12b of the main rope 12 is connected to the counterweight rope end fixing member 14, and the counterweight end fixing member 14 is attached to the support beam 6 as shown in fig. 1 to 3, whereby the counterweight end 12b of the main rope 12 is fixed to the support beam 6. The support beam 6 in embodiment 1 of the present invention corresponds to the support body according to claim 2.
In the 4 th step, since the rope fixture 54 and the traction rope 53a are removed from the main rope 12, even when the length of the main rope 12 from the counterweight return sheave 9 to the counterweight end 12b is short and the counterweight end 12b does not reach the support beam 6, the main rope 12 is moved by pulling the portion of the main rope 12 closer to the counterweight end 12b than the counterweight return sheave 9, whereby the length of the portion of the main rope 12 closer to the counterweight end 12b than the counterweight return sheave 9 can be adjusted.
Fig. 10 is a schematic view showing a step 6 (S6 in fig. 4) of the elevator mounting method as viewed in the direction of the arrow denoted by C-C in fig. 3. The 6 th step in embodiment 1 of the present invention corresponds to the ascending/descending body hoisting step in claim 2.
In the 6 th step, the portion of the main ropes 12 on the car end 12a side of the car return sheave 8 is pulled, and the counterweight 3 is lifted. The 6 th step is performed as follows.
The hoist 53 is connected to a portion of the main rope 12 on the car end 12a side of the car return sheave 8 via a traction rope 53 a.
By winding the traction rope 53a with the winch 53, the portion of the main rope 12 on the car end 12a side of the car return sheave 8 is pulled downward. Since the counterweight end 12b of the main rope 12 is fixed to the support beam 6 by the counterweight rope end fixing member 14, the portion of the main rope 12 closer to the counterweight end 12b than the counterweight return sheave 9 moves toward the car end 12a, the length between the counterweight return sheave 9 and the counterweight rope end fixing member 14 of the main rope 12 is shortened, and the counterweight 3 is lifted. Then, the counterweight 3 is hoisted to the upper part of the hoistway 1.
Fig. 11 is a schematic view showing a step 7 (S7 in fig. 4) of the elevator installation method as viewed in the direction of the arrow denoted by C-C in fig. 3.
In the 7 th step, the portion of the main rope 12 closer to the car end 12a than the counterweight suspending sheave 11 is temporarily fixed to the support beam 6 by the rope fixing member 54, and the counterweight 3 is held in the upper portion of the hoistway 1. In addition, the haul line 53a is detached from the main line 12, and the winch 53 and the haul line 53a are removed.
Fig. 12 is a schematic view showing the 8 th step (S8 in fig. 4) of the elevator mounting method as viewed in the direction of the arrow denoted by C-C in fig. 3.
In step 8, the main ropes 12 are wound around the car return sheave 8 and the car suspending sheave 10 in this order from the counterweight end 12b side to the car end 12a side of the main ropes 12, and the portions of the main ropes 12 closer to the car end 12a side than the car suspending sheave 10 are fixed to the support beam 6 at positions above the car suspending sheave 10. The 8 th step is performed as follows.
The car 2 to which the car suspending sheave 10 is attached is placed below the upper end of the car lifting area.
In step 3, the main ropes 12 are wound around the car return sheave 8. In the 8 th step, the portions of the main ropes 12 on the car end 12a side of the car return sheave 8 are wound around the pulleys of the car suspension sheave 10, the car end 12a of the main ropes 12 is suspended to the upper portion of the hoistway 1 by the chain block 52, the car end 12a of the main ropes 12 is connected to the car rope end fixing member 13, and the car rope end fixing member 13 is attached to the support beam 6 as shown in fig. 1 to 3, whereby the car end 12a of the main ropes 12 is fixed to the support beam 6 by the car rope end fixing member 13.
The rope fixing 54 is detached from the main rope 12 and the support beam 6, and the scaffold 51 is removed from the hoistway 1.
As described above, the elevator is installed through the 1 st step to the 8 th step.
According to the elevator installation method of embodiment 1 of the present invention, since the hoisting machine 7 is hoisted using the support beam 6, the car return sheave 8, and the heavy use return sheave 9 after the main ropes 12 are wound around the pulleys of the hoisting machine 7, the main ropes 12 can be easily wound around the pulleys of the hoisting machine 7.
The chain block 52 attached to the hoistway top 1a hoists the car return sheave 8, the counterweight return sheave 9, and the main ropes 12. The car return sheave 8, the counterweight return sheave 9, and the main ropes 12 are lighter than the hoisting machine 7. Therefore, while the chain block having a rated load equal to or greater than the weight of the hoisting machine has been used in the related art when the hoisting machine is hoisted using the chain block, in embodiment 1 of the present invention, since the hoisting machine 7 is not hoisted using the chain block 52, the chain block 52 having a rated load smaller than the weight of the hoisting machine 7 can be used, and the chain block 52 having a small size and a light weight can be used as compared with the related art.
In embodiment 1 of the present invention, the support beam 6, the car return sheave 8, and the reuse return sheave 9 are devices used for running of an elevator installed by the elevator installation method according to embodiment 1 of the present invention. In hoisting of a conventional hoisting machine, a sheave support frame is necessary as a device used only for hoisting of the hoisting machine, but in embodiment 1 of the present invention, the sheave support frame is not necessary, and the increase in the installation cost and the installation process can be suppressed.
Further, since the hoisting machine 7 can be hoisted not only but also the car 2 to which the car suspending sheave 10 is assembled and the counterweight 3 to which the counterweight suspending sheave 11 is assembled can be hoisted in the same manner as the hoisting machine 7, the main ropes 12 can be easily hung on the sheave of the car suspending sheave 10 and the sheave of the counterweight suspending sheave 11.
In addition, when the hoisting machine 7 is hoisted by the main ropes 12, the main ropes 12 are wound around the pulleys of the car return sheave 8, so that the winch 53 can be installed in the lower part of the hoistway 1, and it is not necessary to install hoisting equipment such as a winch in the hoistway ceiling part 1a in order to hoist the hoisting machine 7, and therefore, the installation work is easy.
Further, since the main rope 12 is wound around the sheave of the hoisting machine 7, the counterweight end portion 12b side of the main rope 12 is fixed, and the hoisting machine 7 is hoisted by pulling the car end portion 12a side, the winch 53 having a small rated load, a small profile, and a light weight can be used as compared with a winch in which a bead wire is fixed to the hoisting machine 7 and hoisted.
When the main rope 12 is pulled by the winch 53, the winch 53 which is smaller than the winch 53 can be used by connecting the main rope 12 with the pull rope 53a which is thinner, lighter, and more flexible than the main rope 12 and winding the pull rope 53a by the winch 53.
In addition, when the main ropes 12 are temporarily fixed, the end portions of the main ropes 12 are not fixed like the car rope end fixing member 13 and the counterweight rope end fixing member 14, but the rope fixing members 54 are used to fix arbitrary positions of the intermediate portions of the main ropes 12, so the main ropes 12 can be easily fixed.
In embodiment 1 of the present invention, the car end 12a and the counterweight end 12b of the main ropes 12 are fixed to the support beam 6, but the present invention is not limited thereto. For example, the car suspension sheave 10 and the counterweight suspension sheave 11 are not provided, and the car end 12a of the main rope 12 may be connected to the car 2, and the counterweight end 12b of the main rope 12 may be connected to the counterweight 3. In this case as well, since the counterweight end portion 12b of the main rope 12 moves upward by winding the haul rope 53a with the winch 53 in the 6 th step, the counterweight 3 connected to the counterweight end portion 12b also moves upward.
Further, in embodiment 1 of the present invention, the counterweight end portion 12b side of the main rope 12 corresponds to one end side of claim 1 and claim 2 of the present invention, and the car end portion 12a side corresponds to the other end side of claim 1 and claim 2 of the present invention, but the counterweight end portion 12b side may correspond to the other end side of claim 1 and claim 2 of the present invention, and the car end portion 12a side may correspond to one end side of claim 1 and claim 2 of the present invention. For example, in the 2 nd step, the part of the main rope 12 closer to the car end 12a than the hoisting machine 7 may be fixed to the support beam 6 by the rope fixing member 54, and in the 3 rd step, the counterweight end 12b of the main rope 12 may be connected to the winch 53 by the traction rope 53a, and the traction rope 53a may be wound by the winch 53, whereby the part of the main rope 12 closer to the counterweight end 12b than the counterweight return sheave 9 may be pulled downward. In this case as well, the length between the counterweight return sheave 9 and the rope fixing member 54 of the main rope 12 is shortened, and the hoisting machine 7 can be lifted.
In fig. 6 showing the 2 nd step of embodiment 1 of the present invention, the part of the main rope 12 on the counterweight end 12b side of the main rope sheave 9 for comparison is fixed to the support beam 6 by the rope fixing member 54, but the part of the main rope 12 between the hoisting machine 7 and the counterweight sheave 9 may be fixed to the support beam 6 by the rope fixing member 54. In this case, since the counterweight return sheave 9 does not need to be used for hoisting the hoisting machine 7, the counterweight return sheave 9 may be installed after hoisting the hoisting machine 7.
Further, a support member fixed to the hoistway may be provided between the hoisting machine 7 and the support beam 6, and the portion of the main rope 12 between the hoisting machine 7 and the counterweight return sheave 9 may be fixed to the support member by a rope fixing member 54. After the hoisting machine 7 is hoisted to the support member, the rope fixing members 54 are detached from the support member, and then the portions of the main ropes 12 between the hoisting machine 7 and the counterweight return sheave 9 are fixed to the support beam 6 by the rope fixing members 54, and the hoisting machine 7 is hoisted to the lower surface of the support beam 6. In this case, since the length between the hoisting machine 7 of the main rope 12 and the rope fixing member 54 can be shortened to suppress the swing of the hoisting machine 7, the hoisting machine 7 can be stably hoisted easily.
In embodiment 1 of the present invention, the support beam 6 corresponds to the support body of the present invention, but is not limited thereto. The support body may be any member fixed to the hoistway, such as a car guide rail.
In embodiment 1 of the present invention, the main ropes 12 are wound around the pulleys of the hoisting machine 7 to hoist the hoisting machine 7, and the main ropes 12 are wound around the pulleys of the counterweight suspending sheave 11 to hoist the counterweight 3, but the present invention is not limited thereto, and the main ropes 12 may be wound around only one of the pulleys of the hoisting machine 7 and the counterweight 3 to hoist.
