Detailed Description
Hereinafter, embodiments of an adjusting jig for an emergency stop device, and an adjusting method for an elevator will be described with reference to fig. 1 to 8. In the drawings, the same components are denoted by the same reference numerals.
1. Examples of the embodiments
1-1 structural example of elevator
First, the structure of an elevator using an adjusting jig according to an embodiment (hereinafter, referred to as "present example") will be described with reference to fig. 1. Fig. 1 is a schematic configuration diagram showing an elevator.
An elevator 1 shown in fig. 1 includes a car 10 that ascends and descends in an elevator shaft provided in a building structure, a guide rail 12 that movably supports the car 10, a main rope 13, and the like. The car 10 includes 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 isolating member 7. The upper frame 4 is disposed above the car room 2, and the lower frame 5 is disposed below the car room 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 safety device 20 is provided at a lower portion of the car 10 and stops the ascending and descending movement of the car 10 in an emergency. The safety device 20 is disposed opposite to the guide rail 12.
1-2. emergency stop device
Next, the structure of the safety 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 and 22, guide members 23 and 23 for guiding the stoppers 22 and 22, and a lift portion 24. The safety device 20 includes a biasing member, not shown, that biases the braking members 22 and 22. The stopper 22, the guide member 23, and the biasing member are housed in the case 21.
The two braking members 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 and 22 face the both sides of the sliding portion 12a is referred to as a holding direction. Further, an opening 26 is formed in the case 21. The opening 26 is an observation window for observing the distance between the two stoppers 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 in the facing direction R orthogonal to the vertical direction and also orthogonal to the clamping direction. The facing direction R is parallel to the width direction, which is the opening and closing direction of the doors 3 of the car 10.
In the emergency stop device 20 of the present example, the length of the opening 26 in the clamping direction is set to be longer than the length in the vertical direction. The size of the opening 26 is not limited to the above example.
A lift portion 24 is connected to the upper portions of the two braking members 22, 22. The lift-out portion 24 protrudes upward in the vertical direction from the upper portion of the case 21. In an emergency, when the lifting portion 24 is lifted upward in the vertical direction, the two braking members 22 and 22 connected to the lifting portion 24 are also lifted upward. In addition, the two braking members 22, 22 approach each other in the clamping direction guided by the guide members 23, 23. The two braking members 22, 22 hold the sliding portion 12a of the guide rail 12. As a result, the elevator car 10 is braked in its vertical movement.
In order to prevent the housing 21 from interfering with the guide rail 12 or the braking member 22 from being detached from the guide rail 12 when the car 10 vibrates, the emergency stop device 20 needs to be adjusted in position in the opposing direction R.
2. Adjusting clamp
Next, referring to fig. 4 to 8, the adjusting jig 30 for adjusting the position in the facing direction R in the safety device 20 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 longitudinal ends of the main surface portion 31; and a screw joint portion 33 constituted by a nut. The engaging portion 32 is formed by bending two end portions of the main surface portion 31 substantially 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 26 of the emergency stop device 20.
The length of the two engagement portions 32 and 32 in the adjustment jig 30 is set to be shorter than the length of the opening in the clamping direction in the opening portion 26 of the emergency stop device 20 and longer than the length of the opening in the vertical 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 shape, and may be any shape as long as it can be inserted into the opening 26 of the emergency stop device 20 and can be engaged with the edge 26a of the opening 26 of the emergency stop device 20 by the engaging portion 32.
The screw coupling portion 33 is fixed to the main surface portion 31. Further, a through hole is formed in the main surface portion 31 at a portion to which the screw portion 33 is fixed. A jack bolt 40 for adjustment is screwed to the screwed portion 33. In the present example, an example has been described in which a nut is applied as the threaded portion 33, but the present invention is not limited to this, and a female thread may be formed as the threaded portion on an inner wall surface of a through hole provided in the main surface portion 31.
The number of the screw-fastening portions 33 is not limited to one, and two or more screw-fastening portions 33 may be provided.
Next, a method of attaching the adjustment jig 30 having the above-described configuration 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 mounting 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 substantially 90 degrees, and the engagement portion 32 of the adjustment jig 30 is hooked on one surface of the edge portion 26a (see fig. 7) of the opening portion 26 facing the guide rail 12. Thereby, the adjustment jig 30 is attached to the emergency stop device 20. At this time, the main surface portion 31 and the screw joint portion 33 of the adjustment jig 30 face the flange portion 12b of the rail 12 along the facing direction R.
In addition, although an example in which the opening 26 for observing the distance between the stopper 22 and the guide rail 12 is used as the opening for attaching the adjustment jig 30 has been described, 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 face the flange portion 12b of the rail 12.
Next, a method of adjusting the safety 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 safety device 20 is temporarily fixed to the car 10 and receives a load in a direction approaching the guide rail 12 along the facing direction R. As shown in fig. 7 and 8, after the adjustment jig 30 is attached to the emergency stop device 20, the operator threadedly engages the jack bolt 40 with the threaded portion 33 of the adjustment jig 30.
Next, the jack bolt 40 is tightened, and the tip portion 40a of the jack bolt 40 is brought into contact with the flange portion 12b of the guide rail 12. In consideration of the inclination of the safety device 20 at the time of position adjustment, the position where the tip end portion 40a of the jack bolt 40 abuts against the guide rail 12 is preferably the center side in the clamping direction in the guide rail 12, that is, the vicinity of the sliding portion 12 a.
Then, by tightening the jack bolt 40, the emergency stop device 20 is pressed in a direction away from the guide rail 12 along the facing direction R by the engagement portion 32 of the adjustment jig 30, and the emergency stop device 20 moves along the facing direction R. In addition, the emergency stop device 20 receives a load in a direction approaching the guide rail 12. Therefore, when the jack bolt 40 is loosened, the emergency stop device 20 moves in a direction approaching the guide rail 12 in the opposing direction R. This enables the emergency stop device 20 to adjust the position in the facing direction R with respect to the guide rail 12.
Next, when the position adjustment in the opposing direction R of the safety device 20 is completed, the safety device 20 is formally fixed to the car 10. Through these steps, the position adjustment of the emergency stop device 20 with respect to the opposing direction R of the guide rail 12 is completed. As described above, according to the adjustment method of this example, the position of the safety device 20 in the opposing direction R can be easily adjusted by simply adjusting the fastening amount of the jack bolt 40, and the work time required for adjusting the position of the safety device 20 can be reduced.
When the position adjustment of the safety device 20 is completed and the safety device 20 is formally fixed to the car 10, the jack bolt 40 is detached from the adjustment jig 30. Then, the adjustment jig 30 is rotated by substantially 90 degrees to release the engagement of the edge portion 26a of the opening 26 in the engagement portion 32. And, the adjustment jig 30 is detached from the emergency stop device 20. In this way, the adjustment jig 30 is configured to be attachable to and detachable from the emergency stop device 20, and thus the adjustment jig 30 can be used for position adjustment in the opposing direction R of another emergency stop device or a device provided in the elevator.
In the present example, an example in which the adjustment jig 30 is detachably attached to the emergency stop device 20 has been described, 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-coupling portion to be screw-coupled with the jack bolt 40 may be provided at a position facing the flange portion 12b of the guide rail 12 in the case 21 of the safety device 20.
It is to be noted that 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 scope 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 to this. For example, various other devices provided in the elevator 1, such as a door unit and a slider provided in the car 10, may be applied to position adjustment of the guide rails 12 in the opposing direction R in these devices.
In the present specification, terms such as "parallel" and "orthogonal" are used, but these terms are not limited to "parallel" and "orthogonal" strictly, and may be "substantially parallel" and "substantially orthogonal" including a range in which "parallel" and "orthogonal" can function.
