Description

This disclosure relates to elevator systems.

In conventional elevator systems, the car is provided with a car door locking device. When the car stops outside the door-opening area, the car door locking device mechanically prevents the car door from being moved in the opening direction by an operation from inside the car (see, for example, Patent Document 1).

Patent No. 4292207

In a conventional elevator system such as that described above, for example, when performing maintenance work on equipment installed at the top of the hoistway, a worker moves from the landing onto the car and lands the car on the top floor. The worker then fixes the car to the hoistway using a fixing device. The fixing device is, for example, hooked onto the backing of the guide rail.

After the locking device is applied to the backing, if the brake is released, the cage may move upward or downward, causing the locking device to engage with the backing and making it difficult to remove the locking device from the backing.

In such cases, workers can enter the car through the ceiling rescue exit and manually move the car door and hall door in the opening direction to escape to the hall.

On the other hand, if the car is stopped outside the door-opening area, the car door locking device prevents the car door from being manually opened. For this reason, when performing maintenance work on the car, it is necessary to keep the car stopped in the door-opening area, and if the distance from the top of the car to the equipment to be maintained is large, workability decreases.

This disclosure has been made to solve the problems described above, and aims to provide an elevator system that can improve the ease of performing maintenance work on the car.

The elevator system disclosed herein has a car that moves up and down in a hoistway, a car door attached to the car, a landing door attached to the landing, and an unlocking member, and includes an interlock device that prevents the landing door from opening, a car door locking device that is attached to the car and prevents the car door from opening when the car is outside the door-opening area and allows the car door to open by hitting the unlocking member when the car is within the door-opening area, and unlocks the interlock device, and has a movable member that is movable in a direction parallel to the opening and closing direction of the car door and a guide member that guides the movement of the movable member, and is equipped with an auxiliary unlocking device that is attached to the hoistway, and when the movable member is located in the unlocked position where it overlaps with the unlocking member when viewed from directly above, the car door locking device hits the movable member instead of the unlocking member, allowing the car door to open.

The elevator device disclosed herein can improve the ease of performing maintenance work on the car.

Hereinafter, embodiments will be described with reference to the drawings.
Embodiment 1.
Fig. 1 is a schematic diagram showing an elevator apparatus according to embodiment 1. In the figure, a support beam 2 is provided at the top of a hoistway 1. A hoisting machine 3 is supported on the support beam 2. The hoisting machine 3 has a hoisting machine main body 4 and a drive sheave 5.

The hoist main body 4 has a hoist motor (not shown) and a hoist brake (not shown). The hoist motor rotates the drive sheave 5. The hoist brake keeps the drive sheave 5 stationary. The hoist brake also brakes the rotation of the drive sheave 5.

A suspension body (not shown) is wound around the drive sheave 5. The suspension body may consist of multiple ropes or multiple belts.

A car 6 and a counterweight (not shown) are provided in the hoistway 1. The car 6 and the counterweight are suspended by a suspension body, and move up and down in the hoistway 1 by rotating the drive sheave 5.

Multiple guide rails (not shown) are installed in the elevator shaft 1. The multiple guide rails guide the elevator car 6 and the counterweight as they ascend and descend. The support beam 2 is supported by two or more of the multiple guide rails.

The car 6 is provided with a car door device. The car door device has a first car door 7a and a second car door 7b. The first car door 7a and the second car door 7b open and close the car entrance.

A landing door device is provided at each of the landings on multiple floors. Each landing door device has a first landing door 8a and a second landing door 8b. At each landing, the first landing door 8a and the second landing door 8b open and close the corresponding landing entrance/exit.

In addition, at each landing, the first landing door 8a and the second landing door 8b open and close in conjunction with the first car door 7a and the second car door 7b when the car 6 lands on the floor.

Figure 2 is a front view of the landing door device on a floor other than the top floor in Figure 1, viewed from the elevator shaft 1 side.

A landing door frame 11 is fixed to the upper part of the landing entrance. A landing door rail 12 is provided on the landing door frame 11. The landing door rail 12 is parallel to the width direction of the landing entrance and is horizontal. The width direction of the landing entrance is parallel to the opening and closing operation direction of the first landing door 8a and the second landing door 8b, and is the left-right direction in Figure 2.

A first landing door pulley 13 is provided at a first end of the landing door frame 11 in the width direction of the landing entrance. A second landing door pulley 14 is provided at a second end of the landing door frame 11 in the width direction of the landing entrance. An endless interlocking rope 15 is wound around the first landing door pulley 13 and the second landing door pulley 14.

Each of the first landing door 8a and the second landing door 8b has a landing door panel 16 and a landing door hanger 17. Each landing door hanger 17 is fixed to the upper part of the corresponding landing door panel 16.

Each landing door hanger 17 is provided with a plurality of landing door rollers 18 and a plurality of up thrust rollers (not shown). Each landing door roller 18 moves while rolling on the landing door rail 12 when the first landing door 8a and the second landing door 8b are opened or closed. The first landing door 8a and the second landing door 8b are suspended from the landing door rail 12 and open or close along the landing door rail 12.

Each up thrust roller is disposed directly below the corresponding landing door roller 18. In addition, each up thrust roller prevents the corresponding landing door roller 18 from falling off the landing door rail 12.

The first landing door 8a is connected to the lower part of the interlocking rope 15 via a first landing door connecting fitting 19. The second landing door 8b is connected to the upper part of the interlocking rope 15 via a second landing door connecting fitting 20.

When the interlocking rope 15 circulates due to the opening and closing operation of the first landing door 8a, the second landing door 8b moves in the opposite direction to the first landing door 8a.

An interlock device 21 is provided between the first landing door 8a and the landing door frame 11. The interlock device 21 prevents the first landing door 8a and the second landing door 8b from opening.

The interlock device 21 has a latch 22, an interlock latch 23, a fixed interlock roller 24, and a movable interlock roller 25 which is an unlocking member.

The latch 22 is fixed to the landing door frame 11. The interlock latch 23 is rotatably attached to the landing door hanger 17 of the first landing door 8a. When the first landing door 8a and the second landing door 8b are in the fully closed position, the tip of the interlock latch 23 gets caught on the latch 22, thereby preventing the first landing door 8a and the second landing door 8b from opening.

The fixed interlock roller 24 is arranged coaxially with the rotation axis of the interlock latch 23. The movable interlock roller 25 is attached to the interlock latch 23. The interlock latch 23 and the movable interlock roller 25 rotate around the rotation axis of the interlock latch 23.

Figure 3 is a front view of the car door device in Figure 1 as seen from the landing side. A car door frame 31 is fixed to the upper part of the car entrance. A car door rail 32 is provided on the car door frame 31. The car door rail 32 is parallel to the width direction of the car entrance and is horizontal. The width direction of the car entrance is a direction parallel to the opening and closing operation direction of the first car door 7a and the second car door 7b, and is the left-right direction in Figure 3.

A first car door pulley 33 is provided at a first end of the car door frame 31 in the width direction of the car entrance. A second car door pulley 34 is provided at a second end of the car door frame 31 in the width direction of the car entrance. An endless drive belt 35 is wound around the first car door pulley 33 and the second car door pulley 34.

Each of the first car door 7a and the second car door 7b has a car door panel 36 and a car door hanger 37. Each car door hanger 37 is fixed to the upper part of the corresponding car door panel 36. The first car door 7a and the second car door 7b are suspended from the car door rail 32 and open and close along the car door rail 32.

The first car door 7a is connected to the lower part of the drive belt 35 via a first car door connecting fitting 38. The second car door 7b is connected to the upper part of the drive belt 35 via a second car door connecting fitting 39.

A door motor 40 is fixed on the car door frame 31. Rotation of the door motor 40 is transmitted to the first car door pulley 33. When the first car door pulley 33 rotates, the drive belt 35 circulates and the second car door pulley 34 rotates. This causes the first car door 7a and the second car door 7b to open and close.

A support plate 44 is fixed to the first car door 7a. A door stopper side blade 46 having an L-shaped cross section is attached to the support plate 44 via a first parallel link mechanism 45. The door stopper side blade 46 is arranged vertically.

The first parallel link mechanism 45 has a rod-shaped first upper link 47 and an L-shaped first lower link 48.

The upper end of the first upper link 47 is attached to the support plate 44 so as to be rotatable around the rotation axis 47a. The lower end of the first upper link 47 is rotatably connected to the middle part of the door stopper side blade 46.

The middle part of the first lower link 48 is attached to the support plate 44 so as to be rotatable around the rotation axis 48a. The first end part of the first lower link 48 is rotatably connected to the lower end part of the door stopper side blade 46.

The portion from the middle to the second end of the first lower link 48 intersects with the door stop side blade 46. As a result, the second end of the first lower link 48 protrudes from the door stop side blade 46 on the side opposite the rotation axis 48a.

A hook-shaped locking portion 48b is provided at the second end of the first lower link 48. A guide roller 41 is rotatably attached between the locking portion 48b and the portion of the first lower link 48 that intersects with the doorstop side blade 46. The first lower link 48 is rotatably displaceable between the unlocked position shown in FIG. 3 and the locked position shown in FIG. 4 in conjunction with the movement of the doorstop side blade 46.

A fixed locking element 42 and a guide cam 49 are fixed to the second cage door 7b.

A horizontal guide surface is formed on the upper surface of the guide cam 49. When the first car door 7a and the second car door 7b are in a fully closed state, the guide roller 41 is positioned on the guide surface of the guide cam 49, and the locking portion 48b is positioned in the unlocked position shown in FIG. 3.

When the first car door 7a or the second car door 7b is moved in the opening direction without applying an external force to the first lower link 48, the guide roller 41 moves away from the guide cam 49, and the locking portion 48b moves to the locked position, as shown in Figure 4. In this state, the locking portion 48b gets caught on the fixed locking element 42, preventing the first car door 7a and the second car door 7b from opening.

The door stopper blade 46 can be displaced horizontally with respect to the first cage door 7a between the unlocked position shown in Fig. 3 and the locked position shown in Fig. 4 by rotating the first upper link 47 and the first lower link 48. The locked position is a position closer to the door pocket than the unlocked position.

In addition, the door stop side blade 46 is constantly subjected to a force toward the door pocket side, i.e., the locking position side, due to the action of gravity or spring force. However, when the first car door 7a and the second car door 7b are in a fully closed state, the guide roller 41 is positioned on the guide cam 49. As a result, the first lower link 48 is held in the unlocked position, and the door stop side blade 46 is held on the door stop side, i.e., the unlocking position side.

A restricting member 50 is provided on the support plate 44. The restricting member 50 restricts the range of movement of the door stop side blade 46 toward the door stop side. The restricting member 50 is also positioned so that a small gap is secured between the door stop side blade 46 and the restricting member 50 when the first car door 7a and the second car door 7b are in a fully closed state. For this reason, when the door stop side blade 46 comes into contact with the restricting member 50, a small gap is generated between the guide cam 49 and the guide roller 41.

A door pocket side blade 53 having an L-shaped cross section is attached to the support plate 44 via a second parallel link mechanism 52. The second parallel link mechanism 52 has a second upper link 54 and a second lower link 55.

The middle part of the second upper link 54 is rotatably attached to the support plate 44 around the rotation axis 54a. The first end part of the second upper link 54 is rotatably connected to the middle part of the door pocket side blade 53.

The first end of the second lower link 55 is attached to the support plate 44 so as to be rotatable around the rotation axis 55a. The second end of the second lower link 55 is rotatably connected to the lower end of the door pocket side blade 53.

The door pocket side blade 53 is arranged parallel to the door stop side blade 46, i.e., vertically. The door pocket side blade 53 can be displaced horizontally by the rotation of the second upper link 54 and the second lower link 55.

A lever 56 is provided on the top of the first car door 7a. The lever 56 is rotatable around a rotation shaft 56a. The rotation shaft 56a is disposed in the middle of the lever 56. A lever roller 57 is provided on a first end of the lever 56.

A roller guide 58 is fixed to the car door frame 31. When the first car door 7a is in the closed position, the roller guide 58 comes into contact with the lever roller 57.

A connecting rod 59 is connected between the second end of the lever 56 and the second end of the second upper link 54. The door pocket side blade 53 is constantly pushed toward the door stopper side by gravity or spring force.

When the first cage door 7a is in the closed position, the lever roller 57 contacts the roller guide 58, and the door pocket side blade 53 is separated from the fixed side interlock roller 24 and the movable side interlock roller 25.

3, the door pocket side blade 53 is displaced toward the door stop side blade 46. The gap between the door stop side blade 46 and the door pocket side blade 53 becomes smaller, and the fixed side interlock roller 24 and the movable side interlock roller 25 are gripped between the door stop side blade 46 and the door pocket side blade 53.

In addition, the configuration that allows the door pocket side blade 53 to be displaced horizontally is not essential, and the door pocket side blade 53 may be fixed to the first cage door 7a.

The cage door locking device 60 in embodiment 1 has a support plate 44, a first parallel link mechanism 45, a door stop side blade 46, a guide roller 41, a fixed locking element 42, a guide cam 49, a limiting member 50, a second parallel link mechanism 52, a door pocket side blade 53, a lever 56, a lever roller 57, a roller guide 58, and a connecting rod 59.

The car door locking device 60 is provided on the car 6 and prevents the first car door 7a and the second car door 7b from opening when the car 6 is located outside the door opening area. The door opening area is an area in which the opening of the first car door 7a and the second car door 7b is permitted when the car 6 lands on the floor during the ascent or descent process of the car 6.

In addition, when the car 6 is located within the door-opening area, the car door locking device 60 contacts the movable interlock roller 25, thereby allowing the first car door 7a and the second car door 7b to open and unlocking the interlock device 21.

Figure 5 is a front view of the landing door device on the top floor in Figure 1, seen from the elevator shaft 1 side. The configuration of the landing door device on the top floor is the same as the configuration of the landing door devices on floors other than the top floor. For this reason, the configuration of the landing door device other than the first landing door 8a, the second landing door 8b, the landing door frame 11, and the interlock device 21 is omitted in Figure 5.

An auxiliary unlocking device 61 is provided in the elevator shaft 1. In the first embodiment, the auxiliary unlocking device 61 is disposed above the interlock device 21 of the landing door device on the top floor.

The auxiliary unlocking device 61 has a guide member 62, a first fixed leg 63, a second fixed leg 64, a conveying body 65, a movable member 66, a stopper 67 as a positioning member, and an anti-misalignment spring 68.

The guide member 62 is attached to the landing door frame 11 via a first fixed leg 63 and a second fixed leg 64. The first fixed leg 63 and the second fixed leg 64 are arranged at a distance from each other in the width direction of the landing entrance. The guide member 62 is arranged parallel to and horizontally in the width direction of the landing entrance.

The conveyor 65 is supported by a guide member 62. The conveyor 65 is movable along the guide member 62 in a direction parallel to the opening and closing direction of the first car door 7a, i.e., in the width direction of the landing entrance.

The movable member 66 is provided on the conveyor 65. This allows the movable member 66 to move along the guide member 62 in a direction parallel to the opening and closing direction of the first car door 7a. That is, the guide member 62 guides the movement of the movable member 66.

In the first embodiment, the movable member 66 is the same roller as the movable interlock roller 25. Therefore, the diameter of the movable member 66 is the same as the diameter of the movable interlock roller 25.

The stopper 67 is attached to the guide member 62. The stopper 67 also positions the movable member 66 in the unlocked position. The unlocked position is a position where the movable member 66 overlaps the movable interlock roller 25 when viewed from directly above.

The anti-misalignment spring 68 is provided between the second fixed leg 64 and the conveying body 65. The anti-misalignment spring 68 applies a force to the conveying body 65 in a direction in which it contacts the stopper 67. That is, the anti-misalignment spring 68 applies a force to the movable member 66 via the conveying body 65 in a direction in which it approaches the stopper 67. The anti-misalignment spring 68 in embodiment 1 is a tension spring. The conveying body 65 contacts the stopper 67, thereby positioning the movable member 66 in the unlocked position.

When the movable member 66 is positioned in the unlocked position, the auxiliary unlocking device 61 allows the car door locking device 60 to open the first car door 7a by causing the car door locking device 60 to contact the movable member 66 instead of the movable side interlock roller 25.

Figure 6 is an enlarged front view of the auxiliary unlocking device 61 and the interlock device 21 of Figure 5, showing the auxiliary unlocking device 61 and the interlock device 21 close together. Figure 7 is a side view showing the conveying body 65 and the movable member 66 of Figure 6.

5 and 6, the movable member 66 is in the unlocked position. Therefore, the vertical line C1 passing through the center of the movable member 66 passes through the center of the movable interlock roller 25.

The conveying body 65 has a plate 71, a pair of main rollers 72, and a pair of auxiliary rollers 73. The movable member 66, the pair of main rollers 72, and the pair of auxiliary rollers 73 are provided on the plate 71. The pair of main rollers 72 and the pair of auxiliary rollers 73 are arranged on the opposite side of the plate 71 to the movable member 66.

The pair of main rollers 72 move while rolling on the guide member 62 when moving the conveying body 65. Each auxiliary roller 73 is disposed directly below the corresponding main roller 72. In addition, each auxiliary roller 73 prevents the corresponding main roller 72 from falling off the guide member 62.

The guide member 62 may be a rail member similar to the landing door rail 12. Each main roller 72 may be a roller similar to the landing door roller 18. Each auxiliary roller 73 may be a roller similar to the up thrust roller. This makes it possible to suppress an increase in the number of parts.

Figure 8 is a front view showing the movable member 66 in Figure 6 moved to the standby position. The standby position is a position away from the unlocked position and away from the unlocked position in the closing direction of the first landing door 8a. Therefore, in Figure 8, the straight line C1 is away from the movable interlock roller 25.

The stopper 67 can be selectively attached to the guide member 62 in either a first position shown in FIG. 6 or a second position shown in FIG. 8. The first position is a position for positioning the movable member 66 in the unlocking position. The second position is a position for positioning the movable member 66 in the standby position.

The stopper 67 in the first embodiment is screwed to the guide member 62. A screw hole is provided at the first position and the second position in the guide member 62.

When the movable member 66 is positioned in the standby position, even if the car door locking device 60 is positioned in the same vertical position as the movable member 66, the car door locking device 60 does not come into contact with the movable member 66, and therefore the opening operation of the first car door 7a and the second car door 7b is prevented.

When the movable member 66 is in the unlocked position, if the car door locking device 60 is positioned in the same vertical position as the movable member 66, the car door locking device 60 comes into contact with the movable member 66, allowing the first car door 7a and the second car door 7b to open. At this time, the movable member 66 and the conveying body 65 move together with the first car door 7a from the unlocked position in the opening direction of the first car door 7a, as shown in FIG.

When moving car 6 above the door-opening area on the top floor to perform maintenance work on car 6, the worker moves movable member 66 to the unlocked position before moving car 6 above the door-opening area.

If the car 6 becomes unable to move during maintenance work on the car 6, the worker moves into the car from the ceiling rescue exit and manually moves the first car door 7a and the second car door 7b in the opening direction. At this time, the car door locking device 60 hits the movable member 66, allowing the first car door 7a and the second car door 7b to open.

After moving the first car door 7a and the second car door 7b to a certain extent in the opening direction, the worker uses a door fixing jig (not shown) to prevent the first car door 7a and the second car door 7b from moving in the closing direction. After this, the worker manually unlocks the interlock device 21, manually moves the first landing door 8a and the second landing door 8b in the opening direction, and escapes to the landing.

The position of the car 6 when the car door locking device 60 allows the first car door 7a and the second car door 7b to be opened by the auxiliary unlocking device 61 is defined as the auxiliary unlocking position. When the car 6 is in the auxiliary unlocking position, the car entrance partially overlaps with the nearest landing entrance as viewed from inside the car 6. In addition, when the car 6 is in the auxiliary unlocking position, the interlock device 21 faces the car entrance.

In such an elevator system, when the movable member 66 is positioned in the unlocked position, the car door locking device 60 contacts the movable member 66 instead of the movable side interlock roller 25, thereby allowing the first car door 7a to open.

Therefore, even if outside the door-opening area, as long as the movable member 66 is in a position where the car door locking device 60 abuts, the car 6 can be stopped and maintenance work on the elevator shaft equipment can be performed from above the car 6. This allows the car 6 to be brought closer to the elevator shaft equipment for maintenance work to be performed, improving the ease of performing maintenance work on the car 6.

In addition, when the hoist 3 is arranged in a position overlapping with the cage 6 when viewed from directly above, the hoist 3 is installed above the expected position of the cage 6 when the cage 6 bounces up. Even in such a case, maintenance work on the hoist 3 can be performed near the hoist 3, improving the workability of the maintenance work.

In addition, it is possible to reduce the hassle of having to bring a stepladder or platform onto the car 6 to perform maintenance work on elevator equipment that is installed away from the car 6.

In addition, the movable member 66 is positioned in the unlocked position by a stopper 67. This makes it easy to position the movable member 66 in the unlocked position.

In addition, the anti-slip spring 68 applies a force to the movable member 66 in the direction approaching the stopper 67. This makes it easy to hold the movable member 66 in the unlocked position.

In addition, the stopper 67 can be selectively attached to either the first position or the second position with respect to the guide member 62. Therefore, during normal operation, the movable member 66 can be easily positioned in the standby position.

The guide member 62 is attached to the landing door frame 11. This allows the auxiliary unlocking device 61 to be easily installed in the elevator shaft 1. The auxiliary unlocking device 61 can also be easily positioned at an appropriate position relative to the landing entrance and the interlock device 21.

In addition, the auxiliary unlocking device 61 is located above the interlock device 21 on the top floor. This makes it easy to carry out maintenance work on the elevator equipment installed at the top of the elevator shaft 1.

The configuration of the cage door locking device 60 is not limited to the above configuration.

Furthermore, the movable member 66 is not limited to a roller.

Furthermore, the configuration of the conveying body 65 is not limited to the above configuration and may be, for example, configured to slide along the guide member 62.

In addition, the movable member 66 and the conveying body 65 may be configured as a single component.

Furthermore, the positioning member is not limited to the stopper 67.

In addition, the method of attaching the positioning member to the guide member 62 is not limited to screw fastening.

In addition, the installation location of the auxiliary unlocking device 61 is not limited to above the top floor landing, but may also be on an intermediate floor.

The auxiliary unlocking device 61 may also be attached to a structure or equipment other than the landing door frame 11. For example, the first fixed leg 63 and the second fixed leg 64 may be fixed to the elevator shaft wall.

Furthermore, the objects of maintenance work are not limited to the hoisting machine 3, but may also be the control panel, governor, return pulley, cleat, etc.

In addition, the layout of the elevator system is not limited to the layout in Figure 1. For example, the hoisting machine 3 may be installed at a location other than the top of the hoistway 1.

The elevator system may also be an elevator system with a machine room, a double-deck elevator, a one-shaft multi-car elevator, etc. The one-shaft multi-car system is a system in which an upper car and a lower car located directly below the upper car each independently ascend and descend in a common elevator shaft.
