FIG. 6 is a plan view of the hold-stopper according to the embodiment. FIG. 7 is a view taken along the line E-E in FIG. 6. FIG. 8 is a view taken along the line FF in FIG. The hold door stopper 60 used during maintenance inspection of the hold door 10 includes a hook member 61 and a flat plate 65. Among them, the hook member 61 is closed a hook portion 62 which can be hooked to another member by being bent in a hook shape. In other words, the hook member 61 is formed in a J-shape, and the hook portion 62 that is a portion bent in the J-shape is thick enough to pass through the stopper hole 33 of the low-speed hanger 32. It has become. Further, the hook portion 62 is bent at such a size that at least the second intermediate collar 26 can enter inside the bent portion.

The flat plate 65 is a plate member formed in a rectangular plate shape, and the longitudinal direction is the longitudinal direction of the flat plate 65, and a long hole 66 that is a hole penetrating in the thickness direction of the plate is formed. Has been. The flat plate 65 is connected to a straight portion 63 that is a straight portion of the hook member 61 formed in a J-shape. Specifically, in the hook member 61, two through holes 64 perpendicular to the straight part 63 in the plan view of the J shape are formed in the straight part 63, and the two through holes 64 are formed in the straight part 63. It is formed side by side on the side where the hook portion 62 is located and the tip side of the straight portion 63. Bolts 71 can be inserted through the two through holes 64 formed in the straight portion 63.

In this way, the bolt 71 passed through the hole of the hook member 61 can be fixed at an arbitrary position by screwing two nuts and using it as a lock nut. As the two nuts, for example, a nut with a flange is used as a nut positioned inside each bolt 71, and a nut for fixing the flanged nut 73 at an arbitrary position is positioned outside with each bolt 71. It is preferable to use a normal nut 72.

The flat plate 65 is inserted into the through-hole 64 positioned on the distal end side of the straight portion 63 of the hook member 61 and the long hole 66 of the flat plate 65 by inserting one bolt 71 and screwing the flanged nut 73 and the nut 72 together. By connecting, the hook member 61 is connected. That is, the bolt 71 inserted through the through hole 64 positioned on the tip end side of the linear portion 63 of the hook member 61, the flanged nut 73 and the nut 72 that are screwed into the bolt 71, the hook member 61 and the flat plate 65. It is configured as a connecting member 70 that can be connected and fixed by changing the relative angle between the hook member 61 and the flat plate 65.

  Depending on the usage pattern of the hold-a stopper 60, each part constituting the hold-a stopper 60 is fixed to the fixed side of the hold-a header 15 or to the hanger 30 by being locked to the hanger 30. It functions as a moving side locking part that restricts movement.

Specifically, the hold door stopper 60 can be fixed to the hold door header portion 15 by attaching it to both sides of the hanger 30 in the opening / closing direction of the hold door 10. . At this time, the fixed side locking portion on one end side in the opening / closing direction of the hold door 10 functions as a moving side locking portion on the other end side, and the moving side locking portion on one end side in the opening / closing direction of the hold door 10. The part can function as a fixed-side locking part on the other end side. For example, the hook member 61 functions as a fixed side locking portion on one end side in the opening and closing direction of the hold door 10 and functions as a moving side locking portion on the other end side. In this way, the hold-a stopper 60 can be used on both sides in the opening and closing direction of the hold-a 10 with the fixed-side latching portion and the moving-side latching portion being replaced by the members constituting the hold-a stopper 60. It has become.

  The hold-a stopper 60 according to this embodiment is configured as described above, and the operation thereof will be described below. When the elevator is in operation, the elevator user performs call registration and destination registration operations on the operation panels (not shown) installed in the landings and the car on each floor, thereby requesting the floor requested by the user. The car moves between the floors. The user moves between the floors by getting on and off the moving car.

  When the car reaches the landing, the interlock 56 provided in the hold door header 15 and the engagement member on the car side engage with each other, so that the hold door 10 is locked by the interlock 56. Canceled. Further, when the car reaches the landing, engagement members (not shown) provided on both the car door and the hold door 10 are engaged with each other to open and close the car door. Along with this, the hold door is also opened and closed.

  The holder 10 is opened and closed by moving the hanger 30 along the hanger rail 20 in the horizontal direction while the hanger roller 35 rolls on the hanger rail 20, so that the holder 10 also moves in the horizontal direction together with the hanger 30. . At that time, a rope 45 wound around the sheave 40 is connected to the high speed side hanger 31 by a high speed side rope stopper 46, and an operation sheave support portion 43 that supports the sheave 40 is connected to the low speed side hanger 32. Is attached. For this reason, the movement of the high speed side hanger 31 and the low speed side hanger 32 is transmitted between both via the movement of the rope 45 and the sheave 40.

  Specifically, the low-speed hanger 32 moves along the low-speed rail 22 integrally with the sheave 40 at the same speed as the sheave 40 when the operation sheave support 43 is attached. On the other hand, since the high speed side hanger 31 is connected to the rope 45 by the high speed side rope stopper 46, the high speed side hanger 31 has the same speed as that of the rope 45 in the portion where the high speed side rope stopper 46 is located. Move along 21. The portion of the rope 45 located on the side close to the low-speed hanger 32 is connected to the header case 16 by the case-side rope stopper 47, so that when the sheave 40 moves together with the operation sheave support 43, the rope 45 Rotates relative to the sheave 40.

  For this reason, when the sheave 40 moves, the portion of the rope 45 on the high speed side rope stopper 46 side moves in the same direction as the movement direction of the sheave 40 at a speed twice the moving speed of the sheave 40. For this reason, the high speed side hanger 31 moves in the same direction as the movement direction of the low speed side hanger 32 at a speed twice the moving speed of the low speed side hanger 32. As a result, when the hold door 10 is opened and closed, the high speed side door 11 opens and closes at a speed twice that of the low speed side door 12. When the door is closed, the hold door 10 is in a door-closed state because the high-speed door 11 and the low-speed door 12 are aligned in the opening and closing direction. On the other hand, when the door is opened, the high speed side door 11 and the low speed side door 12 are retracted from the communication path between the inside of the car and the landing, and are in a state of being overlapped. The door is opened by opening and closing the side door 12 at a double speed.

  Elevators that operate as described above perform maintenance work regularly or in the event of a malfunction, etc., but this maintenance work stops the operation of the elevator and performs inspection work and parts replacement work for each part. Do. In this maintenance work, the hold door 10 is also performed as necessary. Next, a case where maintenance work is performed on the hold door 10 will be described.

  When performing maintenance work on the hold door 10, the hold door 10 is in a state in which the hold door stopper 60 is attached to the hold door header 15 with the door door fully opened, and the hold door 10 is fixed by the hold door stopper 60. Do. The hold-a stopper 60 is attached to the hold-a header portion 15 from the car.

  For this reason, when the hold door 10 is fixed, in order to attach the hold door stopper 60 to the hold door header portion 15, first, the hold door stopper 60 is placed in a position where it can be attached to the hold door header portion 15 from above the car. , Move the car. That is, the car is moved to a position where the hold-a header portion 15 is exposed to the worker on the car.

  In a state where the operator has entered the car, when the car is moved to a position where the hold door header 15 is exposed with respect to the position of the worker, the hold door 10 is fully opened and the hold door stopper 60 is moved to the hold door header. Attach to part 15. The hold-a stopper 60 is mounted so as to restrict the movement of the hanger 30 from both sides in the moving direction of the hanger 30 in the open hanger 30.

FIG. 9 is a detailed plan view of the hold-a header portion on the side where the hanger is located when the door is open. When attaching the hold-a stopper 60 to the front end side in the moving direction when moving the hanger 30 in the door opening direction, first, the hook portion 62 of the hook member 61 included in the hold-a stopper 60 is attached to the stopper of the low-speed side hanger 32. Pass through the hole 33. That is, when the hold-a stopper 60 is attached to the hanger 30 in the vicinity of the first low-speed side collar 23 or the first intermediate collar 25 (both see FIG. 2), the hook portion 62 of the hook member 61 is attached to the low-speed side hanger. The high speed side hanger 31 is passed through the 32 stopper holes 33. As a result, the hook member 61 of the hold-a stopper 60 is hooked into the stopper hole 33 of the low-speed hanger 32, and the low-speed hanger 32 is locked by the hook member 61. On the distal end side of the hanger 30 in the direction in which the holder 10 is opened, the hook member 61 is engaged with the stopper hole 33 formed in the low speed side hanger 32 as described above, thereby being engaged with the low speed side hanger 32. It functions as a part.

The hold-a stopper 60 faces the hook member 61 or the flat plate 65 so as to be positioned on the moving direction when the hanger 30 is moved in the opening direction, and brings the connecting member 70 to the outside of the header case 16. In this state, the flange portion of the flanged nut 73 included in the connecting member 70 is hooked on the end portion of the outer surface of the header case 16 where the hold-a stopper 60 is located.

  Specifically, the bolt 71 of the connecting member 70 is oriented in the same direction as the bolt 28 (see FIG. 2) for attaching the hanger rail 20 to the header case 16, and the flanged nut 73 is placed on the surface of the header case 16 where the hanger rail 20 is located. The flange of the flanged nut 73 is hooked on the end of this surface. At the front end side of the hanger 30 in the direction in which the hold door 10 is opened, the connecting member 70 is brought into contact with the header case 16 by contacting the hold surface 10 on the outer surface of the header case 16 in the direction opposite to the closing direction. It functions as a fixed side locking portion to be locked.

  Accordingly, the hold-a stopper 60 restricts the movement of the hanger 30 in the moving direction of the hold-a stopper 60 that is hooked in the stopper hole 33 of the low-speed hanger 32 when the hold-a 10 is closed. The movement of the low speed hanger 32 in the closing direction is restricted.

FIG. 10 is a perspective view of the vicinity of the second intermediate collar when the door is open. When the hold door stopper 60 is attached to the opposite side of the moving direction of the hanger 30 in the door open state of the hold door 10 in the door open direction, the hold door stopper 60 is attached to the second intermediate collar 26 (see FIG. 2). Hook. That is, the hook portion 62 of the hook member 61 included in the hold-a stopper 60 is hooked on the second intermediate collar 26. On the rear end side of the hanger 30 in the direction in which the hold door 10 is opened, the hook member 61 functions as a fixed-side locking portion that locks the second intermediate collar 26 that is a member that connects the hanger rail 20 to the header case 16. .

Here, the high-speed hanger 31 is positioned closer to the first intermediate collar 25 than the position of the second intermediate collar 26 when the hold door 10 is fully opened. The hold-a-stopper 60 hooked on the second intermediate collar 26 is in a state where the high-speed hanger 31 is positioned closer to the first intermediate collar 25 than the second intermediate collar 26, and the flat plate 65 is positioned from the hook member 61 to the high-speed hanger 31. Change the angle toward the direction to fix.

That is, the nut 72 of the connecting member 70 and the nut 73 with the flange are tightened in a state where the angle of the flat plate 65 with respect to the hook member 61 is an angle from the hook member 61 toward the side where the high-speed hanger 31 is located. Thus, the flat plate 65 is fixed at the angle. Thereby, when the high speed side door 11 moves in the door opening direction and the high speed side hanger 31 moves in the same direction, the high speed side hanger 31 contacts the flat plate 65. On the rear end side of the hanger 30 in the direction in which the hold door 10 is opened, the flat plate 65 is positioned on the moving direction side of the high speed side hanger 31 when the hold door 10 is closed, and comes into contact with the high speed side hanger 31 to thereby increase the speed side. It functions as a moving side locking portion that locks on the hanger 31.

Incidentally, the flat plate 65, by adjusting the position of the bolt 71 of the connecting member 70 in the elongated hole 66, to adjust the relative position of the plate 65 relative to the hook member 61, a hook member 61 on the second intermediate color 26 It is preferable to make contact with the high-speed hanger 31 in the hooked state.

In the hold door stopper 60 having the flat plate 65, the hook member 61 is hooked on the second intermediate collar 26, and movement of the hold door 10 in the opening / closing direction is restricted. For this reason, the high-speed hanger 31 that is in contact with the flat plate 65 from the side where the first intermediate collar 25 is located also moves further in the door closing direction by the hold-a stopper 60, that is, the high-speed side collar 27 (see FIG. 2) is restricted from moving in the direction in which it is located.

  Accordingly, the movement of the low-speed hanger 32 in the door closing direction is restricted by the hold-a stopper 60 hooked in the stopper hole 33, and the high-speed hanger 31 is held by the second intermediate collar 26. The stopper 60 restricts movement in the door closing direction. Therefore, since the holder 10 suspended from the hanger 30 is restricted from moving in the door closing direction, the door opener holder 10 does not close and is fixed in the door open state.

  Next, the procedure in the case where the hold door 10 is fixed using the hold door stopper 60 and the elevator maintenance work is performed will be described. FIG. 11 is a flowchart showing a procedure in a case where an elevator maintenance work is performed using the hold-a stopper according to the embodiment. When the elevator maintenance work is performed using the hold-a stopper 60, first, the car is moved (step ST11). That is, the elevator operation is stopped and preparations are made for maintenance and inspection, and the car is moved from above the car to a position where the hold door stopper 60 can be mounted on the hold door header 15.

  Next, the hold door 10 is fixed by the hold door stopper 60 (step ST12). That is, the holder 10 is fully opened, and the holder stopper 60 is mounted so as to restrict the movement of the hanger 30 from both sides of the hanger 30 in the moving direction of the hanger 30 in this state. In this way, the hold door stopper 60 is mounted and the movement of the hanger 30 is restricted, so that the hold door 10 suspended from the hanger 30 is fixed.

  When the hold door 10 is fixed, maintenance work is started (step ST13). That is, since the hold door 10 is fixed in an open state, the operator can perform maintenance work around the hold door 10 without worrying about the sudden closing of the hold door 10.

  When the work is completed by performing the maintenance work (step ST14), the hold-a stopper 60 is then removed (step ST15). That is, by removing the hold-a stopper 60 mounted from both sides in the moving direction of the hanger 30, the hanger 30 can be moved, the holder 10 can be opened and closed, and the operation is completed.

The hold-a stopper 60 according to the above embodiment locks the hook member 61 to one of the fixed side of the hold-a header portion 15 or the hanger 30 and either one of the flat plate 65 and the connecting member 70.
