Detailed Description
Hereinafter, a method for installing a hoisting machine according to an embodiment will be described with reference to fig. 1 to 7. In the drawings, common members are denoted by the same reference numerals.
1. Description of the embodiments
1-1. Set position of traction machine
First, the installation position of the hoisting machine installed by the installation method of the hoisting machine according to the embodiment (hereinafter referred to as "this example") will be described with reference to fig. 1, 2, 4, and 5.
Fig. 1 is a side view of an elevator hoistway, and fig. 2 is a top view of the elevator hoistway.
As shown in fig. 1, the elevator of this example is a so-called non-machine-room elevator in which no machine room is provided on top of an elevator hoistway 50 formed in a building structure. As shown in fig. 1 and 2, a pair of car side rails 40 and 41 for guiding a car and a pair of counterweight side rails 42 and 43 for guiding a counterweight, not shown, are vertically provided in the hoistway 50.
As shown in fig. 2, a plurality of guide rail brackets 30, 31, 32 are provided in the hoistway 50. The first and second guide rail brackets 30, 31 are provided on a first inner wall 51 of the elevator hoistway 50, and the third guide rail bracket 32 is provided on a second inner wall 52 of the elevator hoistway 50. The first inner wall 51 and the second inner wall 52 are opposed in the left-right direction as viewed from the hall side where a person or baggage enters and exits the elevator shaft 50.
In addition, during the installation work of the hoisting machine unit 1, a work scaffold or a temporary work floor is provided in the space 10 where the car is installed in the elevator hoistway 50. Then, various operations are performed on the work scaffold or the temporary work floor. Therefore, it is extremely difficult to lift the traction machine unit 1 to the top of the elevator shaft using the space 10. The space 10 is disposed between the first inner wall 51 and the second inner wall 52.
The first guide rail bracket 30 and the second guide rail bracket 31 are disposed on the first inner wall 51 at intervals in the front-rear direction orthogonal to both the lifting direction and the left-right direction of the car. A first counterweight-side rail 42 is fixed to the first rail bracket 30. A second counterweight-side guide rail 43 and a first car-side guide rail 40 are fixed to the second guide rail bracket 31. The second car-side guide rail 41 is fixed to the third guide rail bracket 32. The traction machine unit 1 is lifted to the top of the elevator shaft 50 by passing between the first counterweight-side guide rail 42 and the second counterweight-side guide rail 43.
Further, by fixing the two rails, the second counterweight-side rail 43 and the first car-side rail 40, to the second rail bracket 31, the space occupied by the rail bracket in the elevator hoistway 50 can be reduced, and the elevator hoistway 50 can be miniaturized.
Fig. 4 is a front view showing an upper end portion of the guide rail.
As shown in fig. 4, a hook 55 for suspending a main hoisting machine, not shown, is provided on the ceiling of the elevator hoistway 50. Further, a first hanging hole 61a is formed in an upper end portion of the first car-side rail 40 in the up-down direction. Similarly, a second hanging hole 61b is formed in the upper end portion of the first counterweight-side rail 42 in the up-down direction.
Fig. 5 is a front view showing a state in which the elevator is lifted to a predetermined position.
As shown in fig. 5, a first hoist 62a is provided in the first suspension hole 61a of the first car-side rail 40. A second hoist 62b is provided in the second hoist hole 61b of the first counterweight-side rail 42.
Next, the structure of the hoisting machine unit 1 will be described with reference to fig. 5.
The hoisting machine unit 1 includes a hoisting machine body 2, a mechanical beam 3, and a vibration isolation member 4. The hoisting machine body 2 is provided on the upper part of the mechanical beam 3 via a vibration preventing member 4. The mechanical beam 3 is disposed between the first counterweight-side rail 42 and the second counterweight-side rail 43. In this way, by housing the machine beam 3 in the two counterweight guide rails 42, 43, the hoisting machine body 2 can be provided on the machine beam 3 in advance in the lower part of the elevator hoistway 50.
The hoisting machine main body 2 is provided with hoisting machine side hangers 60a and 60b on its side surface, that is, on its side surface facing the first counterweight side rail 42, the second counterweight side rail 43, and the first car side rail 40. The first hoist 62a is coupled to the first hoisting machine side bracket 60a, and the second hoist 62b is coupled to the second hoisting machine side bracket 60b.
1-2 mounting method of traction machine
Next, a method of installing the hoisting machine unit 1 will be described with reference to fig. 3 to 5.
Fig. 3 is a flowchart showing a method of installing the hoisting machine.
As shown in fig. 3, first, the operator carries products such as the hoisting machine body 2, the machine beam 3, the guide rails 40, 41, 42, 43, etc. into the lower part of the elevator hoistway 50 (step S11). Next, the worker attaches the guide rails 40, 41, 42, 43 to the guide rail brackets 30, 31, 32, and erects the guide rails 40, 41, 42, 43 in the elevator shaft 50 (step S12). Then, the operator positions the guide rails 40, 41, 42, 43 (step S13).
Next, the operator assembles the hoisting machine body 2 and the machine beam 3 at the lower part of the elevator hoistway 50 (step S14). That is, the hoisting machine body 2 is provided above the mechanical beam 3 via the vibration preventing member 4. Thereby, the hoisting machine unit 1 shown in fig. 3 can be assembled. In addition, by assembling the hoisting machine body 2 and the mechanical beam 3 in advance in the lower part of the elevator hoistway 50, work at a high place can be reduced, and safety can be improved.
Next, a main hoist, not shown, is suspended from the hook 55 shown in fig. 4 and 5, and the hoisting machine unit 1 is lifted to the vicinity of the top of the elevator hoistway 50 by the main hoist (step S15). At this time, a guide device for slidably engaging with the counterweight-side rails 42 and 43 while holding the hoisting machine unit 1 may be attached to the hoisting machine unit 1. This prevents the hoisting machine unit 1 from being shaken and coming into contact with the inner wall of the elevator shaft 50 or other equipment.
As shown in fig. 5, when the hoisting machine unit 1 is lifted to the vicinity of the top of the elevator shaft 50, the worker performs a replacement (replacement) operation of the hoisting machine (step S16). That is, the operator hangs the first hoist 62a from the first hanging hole 61a of the first car-side rail 40, and hangs the second hoist 62b from the second hanging hole 61b of the first counterweight-side rail 42. After the combustion, the first hoisting machine 62a is connected to the first hoisting machine side hanger 60a of the hoisting machine unit 1, and the second hoisting machine 62b is connected to the second hoisting machine side hanger 60b of the hoisting machine unit 1.
The connection between the main hoisting machine and the hoisting machine unit 1 is released, and the main hoisting machine is detached from the hook 55. As a result, the main hoisting machine disappears from above the hoisting machine unit 1, so that a sufficient space can be ensured between the hoisting machine unit 1 and the top of the elevator hoistway 50.
Next, the operator lifts the hoisting machine unit 1 to a predetermined installation position using the first and second lifts 62a and 62b attached to the guide rails 40 and 42 (step S17). Further, by using the two lifts 62a and 62b for lifting, the hoisting machine unit 1 can be lifted to a predetermined installation position in a stable state, and the work efficiency at the time of installation of the hoisting machine unit 1 can be improved.
Next, the machine beam 3 is provided on the counterweight-side rails 42, 43, and the hoisting machine unit 1 is provided on the top of the elevator hoistway 50, that is, on the counterweight-side rails 42, 43 (step S18). By performing such a process, the attachment operation of the hoisting machine unit 1 is completed.
In this way, according to the installation method of the traction machine of the present embodiment, by installing the hoisting machines 62a, 62b on the guide rails 40, 42, it is unnecessary to newly provide the hooks on the top of the elevator shaft 50. Accordingly, since the hoisting machine can be provided without processing the elevator shaft 50, the hoisting machine can be provided independently of the structure of the building structure. As a result, the working efficiency of the hoisting machine can be improved.
2. Modification examples
In the above embodiment, the example in which the hanging holes 61a and 61b are formed in the upper end portions of the first car-side guide rail 40 and the first counterweight-side guide rail 42 has been described, but the present invention is not limited thereto. Next, a modified example of the suspending method of the lifts 62a, 62b will be described with reference to fig. 6 and 7.
Fig. 6 is a front view showing an upper end portion of a guide rail according to a modification, and fig. 7 is a front view showing a state in which the hoisting machine is lifted to a predetermined position by using the guide rail shown in fig. 6.
As shown in fig. 6, a first hanger 63a is detachably provided at an upper end portion of the first car-side rail 40B in the up-down direction. Similarly, a second hanger 63B is detachably provided at an upper end portion of the first counterweight-side rail 42B in the up-down direction. As shown in fig. 7, a first hoist 62a is mounted on the first hanger 63a, and a second hoist 62b is mounted on the second hanger 63b.
Then, the traction machine unit 1 is lifted to a predetermined installation position by the first lifting machine 62a mounted on the first hanger 63a and the second lifting machine 62b mounted on the second hanger 63b.
In this way, according to the suspension method of the lifts 62a, 62B of the modification, the trouble of forming the suspension holes 61a, 61B in the guide rails 40B, 42B can be eliminated. Accordingly, the lifts 62a, 62b can be provided without designing a new guide rail. Further, since the hangers 63a and 63B are detachably attached to the guide rails 40B and 42B, they can be detached from the guide rails 40B and 42B after the attachment work of the hoisting machine. In this way, the hangers 63a and 63b can be used as temporary materials, and can be used not only in a new elevator but also in a modification work of an existing elevator.
The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the spirit of the invention described in the claims.
In the above embodiment, the example in which the main hoisting machine mounted on the hook 55 is used to hoist the hoisting machine to the vicinity of the top of the elevator shaft 50 has been described, but the present invention is not limited thereto. The hoisting machines 62a and 62b may be attached to the guide rails from a state where the hoisting machine is located at the lower part of the elevator hoistway 50, and the hoisting machines may be lifted from the lower part of the elevator hoistway 50 to a predetermined installation position by the hoisting machines 62a and 62b. This can omit the replacement work of the elevator shown in fig. 3, and further improve the work efficiency. Further, since the hook 55 does not need to be provided in the elevator shaft 50, the hoisting machine can be provided independently of the structure of the building structure.
The example in which the hoisting machine side hangers 60a and 60b are provided on the side surface of the hoisting machine body 2 has been described, but the present invention is not limited to this. For example, a hoisting machine side hanger may be provided on the upper part of the hoisting machine body 2 or the machine beam 3.
In the present specification, terms such as "parallel" and "orthogonal" are used, but these terms are not limited to "parallel" and "orthogonal" and include "parallel" and "orthogonal" as well as a state of being substantially "parallel" and "substantially" orthogonal "within a range where the functions thereof can be exhibited.
