Detailed Description
Embodiments of an adjustment jig for an emergency stop device, and an adjustment method for an elevator are described below with reference to fig. 1 to 8. In the drawings, the same components are denoted by the same reference numerals.
1. Description of the embodiments
1-1 Structural example of an Elevator
First, a structure of an elevator using an adjustment jig according to an embodiment (hereinafter, referred to as "this embodiment") will be described with reference to fig. 1. Fig. 1 is a schematic configuration diagram showing an elevator.
The elevator 1 shown in fig. 1 includes a car 10 that moves up and down in a hoistway provided in a building structure, a guide rail 12 that supports the car 10 so as to be movable, a main suspension wire 13, and the like. The car 10 has a hollow car room 2, a door 3 provided in the car room 2, an upper frame 4, a lower frame 5, a vertical frame 6, and a vibration isolation member 7. The upper frame 4 is disposed at the upper portion of the car 2, and the lower frame 5 is disposed at the lower portion of the car 2. The car room 2 is supported by the lower frame 5 via a vibration isolation member 7. The vertical frame 6 connects the upper frame 4 and the lower frame 5.
A pulley 11 is provided at the lower portion of the lower frame 5. A main rope 13 is wound around the pulley 11. The main rope 13 is wound around a hoist, not shown. The hoist is driven, and thereby the car 10 moves up and down in the hoistway.
The slide block 14 and the emergency stop device 20 are provided on both sides in the width direction orthogonal to the up-down direction of the lifting movement in the car 10 and parallel to the opening-closing direction of the door 3. The slider 14 slides on the guide rail 12 erected in the hoistway to guide the movement of the car 10. The guide rail 12 includes a slide portion 12a and a flange portion 12b (see fig. 3 and 8) for sliding the slider 14.
The emergency stop device 20 is provided at a lower portion of the car 10, and emergency stops the lifting movement of the car 10. The emergency stop device 20 is disposed opposite the guide rail 12.
1-2 Emergency stop device
Next, the structure of the emergency stop device 20 will be described with reference to fig. 2 and 3.
Fig. 2 and 3 are perspective views showing the emergency stop device 20.
As shown in fig. 2 and 3, the emergency stop device 20 includes a case 21, two stoppers 22, guide members 23, 23 for guiding the stoppers 22, and a lifting portion 24. The emergency stop device 20 includes a biasing member, not shown, for biasing the stoppers 22, 22. The stopper 22, the guide member 23, and the urging member are housed in the case 21.
The two stoppers 22, 22 are disposed on both sides of the sliding portion 12a of the guide rail 12 with a predetermined interval. Hereinafter, the direction in which the two stoppers 22, 22 face both sides of the sliding portion 12a is referred to as the sandwiching direction. The case 21 is formed with an opening 26. The opening 26 is an observation window for observing the distance between the two stoppers 22, 22 and the guide rail 12. The opening 26 is formed in a surface of the case 21 facing the guide rail 12. That is, the opening 26 is formed on one surface of the opposing direction R orthogonal to the vertical direction and also orthogonal to the sandwiching direction. The opposing direction R is parallel to the width direction, which is the opening and closing direction of the door 3 of the car 10.
In the emergency stop device 20 of the present example, the length of the opening 26 in the gripping direction is set longer than the length in the vertical direction. The size of the opening 26 is not limited to the above example.
A lifting portion 24 is connected to the upper portions of the two stoppers 22, 22. The lifting portion 24 protrudes upward in the vertical direction from the upper portion of the casing 21. In an emergency, when the lifting portion 24 is lifted upward in the up-down direction, the two stoppers 22, 22 connected to the lifting portion 24 are also lifted upward. The two stoppers 22, 22 are guided by the guide members 23, 23 to approach each other in the gripping direction. The two stoppers 22, 22 sandwich the sliding portion 12a of the guide rail 12. As a result, the lifting movement of the car 10 is braked.
In order to prevent the case 21 from interfering with the guide rail 12 or the stopper 22 from being separated from the guide rail 12 when the car 10 vibrates, the emergency stop device 20 needs to be adjusted in the position in the opposing direction R.
2. Adjusting clamp
Next, referring to fig. 4 to 8, an adjustment jig 30 for adjusting the position of the emergency stop device 20 in the opposing direction R will be described.
Fig. 4 is a perspective view showing the adjustment jig 30.
As shown in fig. 4, the adjustment jig 30 is formed by bending a flat plate-like member. The adjustment jig 30 includes: a main surface 31 formed in a substantially rectangular shape; two engaging portions 32, 32 provided at both ends in the longitudinal direction of the main surface 31; and a screw joint 33 constituted by a nut. The engaging portion 32 is formed by bending both end portions of the main surface portion 31 approximately perpendicularly twice. Therefore, the engaging portion 32 is disposed substantially parallel to the main surface portion 31. When the adjustment jig 30 is attached to the emergency stop device 20, the engagement portion 32 engages with an edge portion 26a (see fig. 7) of the opening portion 26 of the emergency stop device 20.
The lengths of the two engaging portions 32, 32 in the adjustment jig 30 are set to be shorter than the length of the opening in the gripping direction in the opening portion 26 of the emergency stop device 20 and longer than the length of the opening in the up-down direction. That is, the adjustment jig 30 is formed in a size that enables insertion of the opening 26 of the emergency stop device 20. The shape of the adjustment jig 30 is not limited to the above-described shape, and may be a shape that can be inserted into the opening 26 of the emergency stop device 20, and that can be engaged with the edge 26a of the opening 26 of the emergency stop device 20 by the engagement portion 32.
The screw-coupled portion 33 is fixed to the main surface portion 31. A through hole is formed in the main surface 31 at a portion where the screw joint portion 33 is fixed. An adjusting jack bolt 40 is screwed to the screwed portion 33. In this example, the nut is applied as the screw joint portion 33, but the present invention is not limited to this, and a female screw may be formed on the inner wall surface of the through hole provided in the main surface portion 31 as the screw joint portion.
The number of the screw-coupling portions 33 is not limited to one, and two or more screw-coupling portions 33 may be provided.
Next, a method of attaching the adjustment jig 30 having the above-described structure to the emergency stop device 20 will be described with reference to fig. 5 and 6.
Fig. 5 and 6 are front views showing the mounted state of the adjustment jig 30.
First, as shown in fig. 5, the adjustment jig 30 is inserted into the case 21 from the opening 26 of the emergency stop device 20. Next, as shown in fig. 6, the adjustment jig 30 is rotated by approximately 90 degrees, and the engagement portion 32 of the adjustment jig 30 is hung on a surface of the edge portion 26a (see fig. 7) of the opening 26 on the side facing the guide rail 12. Thereby, the adjustment jig 30 is attached to the emergency stop device 20. At this time, the main surface 31 and the screw-coupled portion 33 of the adjustment jig 30 face the flange 12b of the guide rail 12 in the facing direction R.
The example in which the opening 26 for observing the distance between the stopper 22 and the rail 12 is used as the opening for attaching the adjustment jig 30 has been described, but the present invention is not limited thereto. When the adjustment jig 30 is attached, the screw coupling portion 33 of the adjustment jig 30 may be an opening that can be opposed to the flange portion 12b of the guide rail 12.
Next, a method of adjusting the emergency stop device 20 using the adjustment jig 30 will be described with reference to fig. 7 and 8.
Fig. 7 and 8 are sectional views showing an adjustment method of the emergency stop device 20.
Here, the emergency stop device 20 is temporarily fixed to the car 10, and receives a load in a direction approaching the guide rail 12 along the opposing direction R. As shown in fig. 7 and 8, after the adjustment jig 30 is attached to the emergency stop device 20, the operator screw-engages the jack bolt 40 with the screw engagement portion 33 of the adjustment jig 30.
Then, the jack-up bolt 40 is tightened so that the tip end portion 40a of the jack-up bolt 40 abuts against the flange portion 12b of the rail 12. In consideration of the inclination of the emergency stop device 20 at the time of the position adjustment, the position where the tip portion 40a of the jack-up bolt 40 contacts the guide rail 12 is preferably the center side in the clamping direction of the guide rail 12, that is, the vicinity of the sliding portion 12 a.
Then, by tightening the jack-up bolt 40, the emergency stop device 20 is pressed by the engagement portion 32 of the adjustment jig 30 in a direction away from the guide rail 12 along the opposing direction R, and the emergency stop device 20 moves along the opposing direction R. In addition, the emergency stop device 20 receives a load in a direction approaching the guide rail 12. Therefore, when the jack-up bolt 40 is loosened, the emergency stop device 20 moves in a direction approaching the guide rail 12 in the opposing direction R. Thereby, the emergency stop device 20 can perform positional adjustment in the opposing direction R with respect to the guide rail 12.
Next, when the position adjustment of the emergency stop device 20 in the opposing direction R is completed, the emergency stop device 20 is fixed to the car 10. By these steps, the position adjustment in the opposing direction R with respect to the guide rail 12 in the emergency stop device 20 is completed. As described above, according to the adjustment method of the present embodiment, the position adjustment in the opposing direction R of the emergency stop device 20 can be easily performed by adjusting only the tightening amount of the jack bolt 40, and the time taken for the position adjustment of the emergency stop device 20 can be reduced.
When the position adjustment of the emergency stop device 20 is completed and the emergency stop device 20 is formally fixed to the car 10, the jack-up bolt 40 is detached from the adjustment jig 30. Then, the adjustment jig 30 is rotated by approximately 90 degrees, and the engagement with the edge portion 26a of the opening 26 in the engagement portion 32 is released. The adjustment jig 30 is detached from the emergency stop device 20. In this way, the adjustment jig 30 is configured to be detachable from the emergency stop device 20, and thus the adjustment jig 30 can be used for adjusting the position of the other emergency stop device in the opposing direction R of the device provided in the elevator.
In this example, the adjustment jig 30 is configured to be detachable from the emergency stop device 20, but the present invention is not limited to this, and the adjustment jig 30 may be fixed to the emergency stop device 20. Alternatively, a screw joint portion to which the jack bolt 40 is screwed may be provided at a position facing the flange portion 12b of the rail 12 in the case 21 of the emergency stop device 20.
The present invention is not limited to the embodiments 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-described embodiment, the example in which the emergency stop device 20 is applied as the device to be adjusted has been described, but the present invention is not limited thereto. For example, various other devices provided to the elevator 1, such as a door unit and a slider provided to the car 10, may be applied to position adjustment in the opposing direction R of the guide rail 12 in these devices.
In the present specification, terms such as "parallel" and "orthogonal" are used, but these terms refer not only to strictly "parallel" and "orthogonal", but also to "substantially parallel" and "substantially orthogonal" states including "parallel" and "orthogonal" and within a range where the functions thereof can be exhibited.
