Fig. 15 is a perspective view showing the 5 th positioning step in the mounting method according to embodiment 1. Fig. 16 is a perspective view of the elevator of fig. 15 as viewed from a direction different from that of fig. 15.
The 5 th positioning step is performed after the 4 th positioning step. In the 5 th positioning step, the car bottom 6 is first lowered to 1 floor. Then, the car frame 7 is assembled to the car platform 6, and the pair of upper guide shoes 10 is attached to the car frame 7.
At this time, the pair of upper guide shoes 10 are pressed against the pair of car guide rails 2, respectively. That is, the pair of upper guide shoes 10 are combined with the pair of car guide rails 2, respectively. Thereby, the pair of upper guide shoes 10, the pair of vertical columns 14, and the upper member 15 are positioned.
Fig. 17 is a perspective view showing the 6 th positioning step in the mounting method according to embodiment 1. Fig. 18 is a perspective view of the elevator of fig. 17 as viewed from a direction different from that of fig. 17.
The 6 th positioning step is performed after the 5 th positioning step. In the 6 th positioning step, the scaffold device 23 is first removed. Then, the car bottom 6 is raised to 2 floors.
Then, a pair of 3 rd car guide rail brackets 4c are attached to the pair of car guide rails 2. Then, each car guide rail 2 is pressed against the corresponding upper guide shoe 10. That is, the pair of car guide rails 2 are combined with the pair of upper guide shoes 10, respectively.
Thereby, the pair of 3 rd car guide rail brackets 4c are positioned. Then, the pair of 3 rd car guide rail brackets 4c after positioning is fixed to the hoistway wall.
Thereafter, a pair of 4 th car guide rail brackets 4d and a pair of 5 th car guide rail brackets 4e are provided corresponding to the positions of the pair of car guide rails 2. In addition, a pair of the 3 rd counterweight guide rail bracket 5c, the 4 th counterweight guide rail bracket 5d, and the 5 th counterweight guide rail bracket 5e is provided corresponding to the position of the pair of counterweight guide rails 3.
Then, a car room, not shown, is assembled to the car bottom 6. Further, equipment such as a counterweight, a hoisting machine, a suspension body, and a control panel not shown is provided in the hoistway 1.
In the first positioning step of the elevator installation method, the car bottom 6 is positioned with respect to the 1 st landing sill 31. In the 2 nd positioning step, the pair of car guide rails 2 are combined with the pair of lower guide shoes 9 provided on the car floor 6, respectively, to position the pair of 1 st car guide rail brackets 4 a.
In the 3 rd positioning step, the car bottom 6 is raised, and the car bottom 6 is positioned with respect to the 2 nd landing sill 32. In the 4 th positioning step, the pair of car guide rails and the pair of lower guide shoes 9 are combined, and the 2 nd car guide rail bracket 4b is positioned.
Therefore, the position of the pair of car guide rails 2 can be easily adjusted without installing a piano wire in the hoistway 1 or using a guide gauge.
Even when the landing is shifted between floors or the landing is twisted in the horizontal plane, the position of the pair of car guide rails 2 can be adjusted with the landing of each floor as a reference. Therefore, the intervals between the landings and the car bottom 6 on the respective floors can be equalized.
In particular, even in a retrofitting process in which existing landing sills 31 and 32 and existing landing door frames 33 are left, the intervals between the landings and the car bottom 6 on the respective floors can be equalized.
Further, work performed on site can be reduced by mounting the safety device 8, the pair of lower guide shoes 9, and the pair of car hanging wheels 11 to the car bottom 6 in advance. Further, the assembly accuracy of the car bottom 6, the safety device 8, the pair of lower guide shoes 9, and the pair of car hanging wheels 11 can be improved.
In the 1 st positioning step, the car bottom 6 is connected to the 1 st landing sill 31 via the car bottom coupler 27. Therefore, the car bottom 6 can be more accurately positioned with respect to the 1 st landing sill 31.
In the 1 st positioning step, the pillars 21 are interposed between the car bottom 6 and the bottom portion 1a, and the height of the pillars 21 is adjusted to level the car bottom 6. This can reduce the load applied to the 1 st landing sill 31. Further, the car bottom 6 can be stably held horizontally, and the pair of first car guide rail brackets 4a can be easily positioned.
In the 5 th positioning step, the pair of upper guide shoes 10 are combined with the pair of car guide rails 2, respectively, in a state where the car floor 6 is lowered to the 1 st landing floor, and the pair of upper guide shoes 10 are positioned. Therefore, the pair of upper guide shoes 10 can be easily positioned.
Further, by assembling the car frame 7 in accordance with the positions of the pair of upper guide shoes 10, the car frame 7 can be easily assembled.
In the 6 th positioning step, after the car bottom 6 is raised, the pair of car guide rails and the pair of upper guide shoes 10 are combined to position the pair of 3 rd car guide rail brackets 4c. Therefore, the pair of 3 rd car guide rail brackets 4c can be easily positioned.
In the 2 nd positioning step, the pair of counterweight guide rails 3 are combined with the guide rail positioning members 22, respectively, to position the pair of 1 st counterweight guide rail brackets 5 a. Therefore, the pair of 1 st counterweight guide rail brackets 5a can be easily positioned. This makes it possible to easily adjust the position of the pair of counterweight guide rails 3.
In the 4 th positioning step, the pair of counterweight guide rails 3 and the guide rail positioning member 22 are combined to position the pair of 2 nd counterweight guide rail brackets 5 b. Therefore, the pair of 2 nd counterweight guide rail brackets 5b can be easily positioned. This makes it possible to easily adjust the position of the pair of counterweight guide rails 3.
The car bottom coupling 27 according to embodiment 1 includes a hook portion 27a and a sill receiving portion 27b. Therefore, the car bottom 6 can be more accurately positioned with respect to the 1 st landing sill 31. This makes it possible to easily determine the positions of the pair of car guide rails 2 with respect to the car bottom 6. That is, the position of the pair of car guide rails 2 can be easily adjusted.
Further, since the hook portion 27a is provided with the insertion portion 27c, the car bottom 6 can be easily positioned with respect to the existing 1 st landing sill 31.
Further, since the sill receiving portion 27b receives the car sill 13, the car floor 6 and the 1 st landing sill 31 can be easily connected.
The rail spacer 22 according to embodiment 1 includes a car bottom mounting portion 22a and a pair of positioning portions 22b. Therefore, the position of the pair of counterweight guide rails 3 can be easily adjusted.
In the above example, the method of positioning and fixing the guide rail after connecting all the guide rail members is described. However, the method may be such that after 1 rail member is positioned and fixed, the next rail member is positioned and fixed in order.
The landing-side end of the car floor received by the car floor receiving portion is not limited to the car sill.
The present invention can also be applied to an elevator having a landing floor of 3 floors or more.
Further, the 1 st landing floor is not limited to the lowermost floor. The 2 nd landing floor is not limited to the floor on the floor immediately above the 1 st landing floor.
In addition, the present invention can be applied to the installation of a newly installed elevator, and can also be applied to the renovation of an existing elevator.
The present invention can be applied to various types of elevators such as an elevator having a machine room, a double-deck elevator, and a single-hoistway multi-car elevator. The one-shaft multi-car system is a system in which a plurality of cars are raised and lowered independently in a common shaft.
