In addition, the up-down direction said here is a direction where each floor | bed overlaps, and is parallel to the direction where gravity acts. The direction in which gravity acts is the downward direction, and the opposite direction of the downward direction is the upward direction.

  The elevator apparatus 10 includes a pair of posts 20, a post support 40, a plurality of transporters, and a partition device 60.

  FIG. 2 shows a pair of posts 20. As shown in FIG. 1, the pair of posts 20 is accommodated in the opening 7 of the building 5. As shown in FIG. 2, the pair of posts 20 have the same structure. The post 20 includes a post body 22 configured by connecting a plurality of post units 21, a base 23, and a rack gear 24.

  The post unit 21 includes four rail members 25, a frame member 26, and a reinforcing member 27. Each of the four rail members 25 is arranged in a posture parallel to each other at a position that becomes a corner of the virtual rectangle. The frame member 26 is accommodated inside the four rail members 25 and is fixed to the four rail members 25. The reinforcing member 27 is connected to a pair of adjacent frame members 26 and extends in a direction crossing the extending direction of the rail member 25.

  The post main body 22 is configured by connecting the post units 21 configured as described above in the direction in which the rail member 25 extends and fixing them together. The direction in which the post body 22 extends is a linear direction. The rail members 25 are connected to each other to form a single rail 28 extending linearly. The rail 28 is an example of a guide portion referred to in the present invention.

  The direction in which the post body 22 extends and the direction in which the rail 28 extends are parallel to each other. A direction in which the post 20 extends and a direction in which the rail 28 extends are defined as a first direction A. The post 20 is installed in the opening 7 so that the first direction A is parallel to the vertical direction.

  The base 23 includes a base body 29, a base connecting member 30, and a base column portion 31. The base body 29 is fixed to one end of each post body 22. The base connecting member 30 connects the base main bodies 29 to each other. As a result, the one post 20 and the other post 20 are connected via the base body 29 and the base connecting member 30.

  The base column portion 31 is fixed to the side of the post body 22 opposite to the side facing the other post 20, and extends in the first direction A. Here, a direction in which the pair of posts 20 are arranged is a second direction B. The second direction B is a direction perpendicular to the first direction A.

  As shown in FIG. 1, the rack gear 24 is fixed to the side of the post body 22 that faces the other post 20. The rack gear 24 extends in the first direction A.

  In the present embodiment, as shown in FIG. 1, the base body 29 abuts the ground 1 on the pair of posts 20 configured as described above. Thus, the post 20 is supported by the ground 1 in the first direction A. In the opening 7, one post 20 is disposed at one end of the first and second edge portions 7a and 7b, and the other post 20 is disposed at the other end of the second and third edge portions 7a and 7b.

  The post support 40 supports the post 20 in a direction perpendicular to the first direction A. The post support 40 is provided on the third and fourth edges 7c and 7d of the opening 7 in the floor 6 of each floor. In this embodiment, since two posts 20 are used, two post supports 40 are provided on each floor. Each post support 40 has the same structure. FIG. 3 is a cross-sectional view of the elevator apparatus 10 shown along the line F3-F3 shown in FIG. FIG. 3 shows a cross section of the post 20 and the post support 40 as viewed from above.

  As shown in FIG. 3, the post support 40 includes, as an example, a support frame 41 having a C-shaped planar shape that opens toward the post 20, and a support guide roller 42 that supports the rail 28 of the post 20. ing.

  The support frame 41 is fixed to the floor 6 of each floor and has a size that accommodates a part of the post 20 inside. The support frame 41 includes a pair of arm portions 43 that protrude inside the opening 7. The post 20 is accommodated between the arm portions 43. The distal end portion 44 of each arm portion 43 faces the rail 28 of the post 20.

  Three guide rollers 42 are provided at the distal end portion 44 of each arm portion 43. FIG. 4 shows an enlarged view of F4 shown in FIG. FIG. 4 shows the post support 40 as viewed from the side. As shown in FIGS. 3 and 4, the three guide rollers 42 sandwich the rail 28 from three directions parallel to a direction perpendicular to the first direction A. More specifically, the two guide rollers 42 sandwich the rail 28 in the second direction. The remaining one guide roller 42 supports the rail 28 from the outside of the opening 7 along a direction perpendicular to the second direction B.

  Each guide roller 42 is rotatable around a rotation axis perpendicular to the first direction A. Each guide roller 42 has a shape in which the inner side is recessed in accordance with the rail 28. Thus, the post support 40 supports the rail 28 in a direction perpendicular to the first direction A. In addition, the recess 28 makes it difficult for the rail 28 to come off between the three guide rollers 42.

  The plurality of transporters can move independently of each other along the post 20, and can accommodate people, luggage, and the like. Each transporter has the same structure. Alternatively, the cages described later may have different cage structures. In short, the transporter only needs to be movable along the post 20 and have a function of transporting people and luggage. In the present embodiment, as an example, an upper carrier 50 and a lower carrier 51 are used. Since the upper carrier 50 and the lower carrier 51 have the same structure, the upper carrier 50 will be described as a representative. In addition, the lower carrier 51 is an example of the carrier located below the direction in which the gravity acts in the present invention.

  As shown in FIG. 1, the upper transporter 50 includes a connection frame 52, a cage 53 provided on the connection frame 52, a transporter operation device 54, and a transporter control unit 55. The connection frame 52 includes a connection frame main body 56 and a pair of portable motors 57 as a drive unit that moves the connection frame main body 56 up and down along the rails 28.

  Both end portions of the connecting frame main body 56 face two rails 28 arranged inside the opening 7 among the four rails 28 of the post 20. Guide rollers 58 that guide the movement of the connection frame 52 relative to the rail 28 are provided at both ends of the connection frame main body 56. As an example, two guide rollers 58 are provided for one rail 28. The two guide rollers 58 are rotatable around a rotation axis parallel to a direction perpendicular to the first direction A. In this embodiment, the two guide rollers 58 are rails in the second direction B. 28 is sandwiched in between. FIG. 3 shows a structure of two guide rollers 58 for one rail 28 by a two-dot chain line. Similarly to the above, two guide rollers 58 are provided for the other rails 28. Each guide roller 58 has a shape in which the inner side is recessed according to the rail 28. As a result, the rail 28 is prevented from coming off between the two guide rollers 58.

  The transporter motors 57 are fixed one by one at a position near the post 20 in the connection frame main body 56. A pinion gear 59 is provided on a rotating shaft (not shown) of the transporter motor 57. The pinion gear 59 meshes with the rack gear 24 of the post 20. In FIG. 3, a state in which the pinion gear 59 is engaged with the rack gear 24 is indicated by a two-dot chain line. The pinion gear 59 moves up and down on the rack gear 24 by the rotation of the transport motor 57, that is, the rotation shaft, and therefore the connection frame 52 moves up and down. The rotation direction of the transporter motor 57, that is, the rotation direction of the pinion gear 59 is controlled in accordance with the elevation of the upper transporter 50.

  The carrying device operating device 54 is provided in a cage 53 provided on the connection frame main body 56. The carrying device operating device 54 is operated by a worker or the like when the upper carrying device 50 is moved up and down.

  The transporter control unit 55 controls the operation of the transporter motor 57. The transporter control unit 55 is connected to the transporter operation device 54 and drives the transporter motor 57 in accordance with an operation input to the transporter operation device 54. For example, when the worker performs an operation for raising the upper carrying device 50, the carrying device controller 55 controls the rotation of the carrying motor 57 so that the upper carrying device 50 is raised.

  The transporter control unit 55 detects the number of teeth of the rack gear 24 using the sensor 200, and detects the moving speed of the upper transporter 50 based on the detection result. When the transporter control unit 55 determines that the moving speed of the upper transporter 50 exceeds the preset safe speed, the transporter motor 57 stops the operation of the transporter motor 57.

  Specifically, the supply of power to the transporter motor 57 is stopped. Then, the transporter control unit 55 operates the automatic fall prevention device 201 for stopping the movement of the upper transporter 50. As an example, the automatic fall prevention device 201 includes a connecting shaft 202 that connects the rotation shafts of the electric motors 57 for both transporters and rotates integrally with the rotation shaft, and a brake unit 203. When actuated, the brake unit 203 sandwiches the connection shaft 202 and stops the rotation of the connection shaft 202 by friction. Since the rotation of the connecting shaft 202 stops, the rotation of the rotating shaft of the transporter motor 57 stops, so that the upper transporter 50 stops moving. The transporter control unit 55 stops the movement of the upper transporter 50 by operating the brake unit 203.

  The automatic fall prevention device 201 may have a structure other than the above structure. The automatic fall prevention device 201 only needs to have a function of stopping the movement of the upper carrier 50.

  Further, the transporter control unit 55 detects the position of the upper transporter 50 relative to the rail 28 by detecting the number of teeth of the rack gear 24. Then, the transporter control unit 55 detects on which floor of the building 5 the upper transporter 50 is located based on the position of the upper transporter 50 with respect to the rail 28.

  Since the structure of the lower carrier 51 is the same as that of the upper carrier 50, the same components are denoted by the same reference numerals. Then, the contents described with reference to the upper carrier 50 are replaced with those based on the lower carrier 51. The transporter control unit 55 of the upper transporter 50 and the transporter control unit 55 of the lower transporter 51 can communicate with each other. Then, the transporter control unit 55 transmits the position information of the transporter to the counterpart transporter control unit 55. Similarly to the upper carrier 50, the carrier controller 55 of the lower carrier 51 can detect on which floor of the building 5 the lower carrier 51 is located.

  As shown in FIG. 1, the partition device 60 is provided between a pair of carriers that are adjacent to each other along the rail 28 among the plurality of carriers. In the present embodiment, the upper and lower transporters 50 and 51 are used as an example, and therefore, one partition device 60 is provided between the upper and lower transporters 50 and 51.

  FIG. 5 is a perspective view showing the partition device 60. As shown in FIGS. 1 and 5, the partition device 60 includes a partition plate 61, a partition device guide portion 62, and a pair of partition device motors as a drive unit that allows the partition device 60 to move up and down along the rails 28. 63, a shock absorber 64, and a partition device controller 65.

  As shown in FIG. 1, the partition plate 61 has a size that covers the entire lower transporter 51 in the first direction A. The surface of the partition plate 61 is a protective surface that receives a fallen object from the upper carrier 50. The partition plate 61 is an example of a partition portion referred to in the present invention. Both ends of the partition plate 61 in the second direction B are opposed to the two rails 28 located inside the opening 7.

  One partition device guide 62 is provided at each end of the partition plate 61. The structure of the partition device guide 62 is the same. The partition device guide portion 62 includes a guide roller support bracket 66 and a guide roller 67.

  The guide roller support bracket 66 extends on both sides in the first direction A across the partition plate 61. The guide roller support bracket 66 includes two arm portions 68 that are separated in the first direction A with respect to one rail 28. Since the guide roller support bracket 66 faces the two rails 28, the guide roller support bracket 66 includes a total of four arm portions 68. The arm portion 68 extends in the second direction B and accommodates the rail 28 inside. In FIG. 5, the rail 28 is indicated by a two-dot chain line.

  Each arm portion 68 is provided with two guide rollers 67. The two guide rollers 67 sandwich the rail 28 in the second direction B. The rotation shaft of each guide roller 67 extends in a direction perpendicular to the first and second directions A and B. Each guide roller 67 is recessed on the inside to match the rail 28.

  In FIG. 3, the guide roller 67 that sandwiches the rail 28 is indicated by a two-dot chain line. In addition, the sandwiching structure of the rail 28 by the guide roller 67 of the guide unit 62 for the partition device is the same as the sandwiching structure of the rail 28 by the guide roller 58 provided in the connecting frame 52 of the upper and lower transporters 50 and 51. . For this reason, the guide roller shown in FIG. 3 shows the two guide rollers 58 and 57, and therefore, is given two reference numerals.

  The partition device motors 63 are fixed one by one to the end of the partition plate 61 facing the post 20. A pinion gear 69 that meshes with the rack gear 24 of the post 20 is provided on the rotating shaft of the partition device motor 63. FIG. 3 shows a state where the pinion gear 69 meshes with the rack gear 24.

  The meshing structure of the pinion gear 59 and the rack gear 24 provided in the transporter motor 57 is the same as the meshing structure of the pinion gear 69 and the rack gear 24 provided in the partition motor 63. For this reason, the two reference numerals 59 and 69 are given to the pinion gear shown in FIG. The pinion gear 69 moves on the rack gear 24 as the rotating shaft of the transporter motor 57 rotates. As a result, the partition device 60 moves up and down along the rail 28. The electric motor 63 for partition devices is an example of the drive part for partition parts said by this invention.

  As shown in FIG. 5, the shock absorbers 64 are provided at both ends of the guide roller support bracket 66 with the partition plate 61 interposed therebetween. The shock absorber 64 is configured by, for example, a spring or the like, and absorbs the shock by contracting when the shock is input along the first direction A in which the rail 28 extends.

  The partition device controller 65 controls the operation of the partition device motor 63. The controller for partition device 65 detects the number of teeth of the rack gear 24 using the sensor 300, and detects the moving speed of the partition plate 61 based on the detection result. When determining that the moving speed of the partition plate 61 exceeds the preset safe speed, the partition device controller 65 stops the operation of the partition device motor 63.

  Specifically, the supply of power to the partition device motor 63 is stopped. Then, the partition device controller 65 operates the automatic fall prevention device 301 that stops the movement of the partition plate 61. As an example, the automatic fall prevention device 301 includes a connecting shaft 302 that connects the rotating shafts of the electric motor 63 for both partition devices and rotates integrally with the rotating shaft, and a brake unit 303. When actuated, the brake unit 303 sandwiches the connection shaft 302 and stops the rotation of the connection shaft 302 by friction. Since the rotation of the connecting shaft 302 stops, the rotation of the rotating shaft of the partition device motor 65 stops, and thus the movement of the partition plate 61 stops. The partition device control unit 65 stops the movement of the partition plate 61 by operating the brake unit 303.

  The automatic fall prevention device 301 may have a structure other than the above structure. The automatic fall prevention device 301 may have a function of stopping the movement of the partition plate 61.

  Further, the partition device controller 65 detects the position of the partition plate 61 relative to the rail 28 based on the detection result of the number of teeth of the rack gear 24. Further, the partition device controller 65 detects on which floor of the building 5 the partition plate 61 is located based on the position of the partition plate 61 with respect to the rail 28.

  The partition device controller 65 can communicate with each transporter controller 55. For this reason, the partition device controller 65 can detect the positions of the upper and lower transporters 50 and 51. The transporter control unit 55 of the upper transporter 50 can detect the position of the partition plate 61 and the position of the lower transporter 51. The transporter control unit 55 of the lower transporter 51 can detect the position of the partition plate 61 and the position of the upper transporter 50.

  Next, the operation of the elevator apparatus 10 will be described together with the operation of the transporter control unit 55 and the operation of the partition device control unit 65. In the present embodiment, the upper carrier 50 moves up and down the reference floor n and the upper floor. The lower carrier 51 moves up and down the reference floor n and its lower floor. In the present embodiment, the reference floor n is the first floor. The upper and lower carriers 50 and 51 can be landed on the reference floor n.

  The carrying device operating device 54 includes, for example, an ascending operation button and a descending operation button. When the ascending operation button is pressed, the transporter performs ascending operation. When the descending operation button is pressed, the transporter descends.

  The upper carrier 50 and the lower carrier 51 can be moved up and down independently up to the floor immediately before the reference floor n based on the operation input to the carrier operating device 54. When reaching the floor immediately before the reference floor n in the operation state approaching the reference floor n, specifically, when the upper carrier 50 reaches the floor immediately before the reference floor n during the descending operation, the lower carrier In 51, when the vehicle reaches the floor immediately before the reference floor n during the ascending operation, the elevator controller 55 stops the ascending and descending operation. After being stopped, when the transporter operating device 54 is operated to operate in a direction away from the reference floor n, the transporter control unit 55 drives the transporter motor 57.

  When it is desired to land on the reference floor n, after stopping at the floor immediately before the reference floor n, the carrier operating device 54 is operated to set the target landing floor to the reference floor n. In this embodiment, the carrier operating device 54 includes a reference floor landing button, and the reference floor n is set as the target landing floor by pressing the reference floor landing button.

  In the upper carrier 50 or the lower carrier 51, when the reference floor n is set as the destination floor by the carrier operating device 54, the information is obtained from the carrier controller 55 and the partition device controller of the other carrier. 65 is transmitted.

  The partition device control unit 65 controls the partition device motor 63 to move to a position where the carrier with the reference floor n set can be landed on the reference floor n with the partition plate 61 as the target floor. The transporter control unit 55 of the other transporter with respect to the transporter for which the reference floor is set as the target floor does not land on the reference floor n until the counterpart transporter leaves the reference floor n, and the partition device 60 The operation of the transporter motor 57 is controlled so as not to contact the shock absorber 64. In addition, when the other-side transporter is landing on the reference floor n and during the landing operation, the transporter operating device 54 of the transporter that is not landing on the reference floor n is operated to serve as the reference floor. Even if the floor n is set, this operation is not executed. It is executed after the other-side transporter leaves the reference floor n.

  As an example of this operation, an operation in the case where the upper carrier 50 is landed on the reference floor n will be described. First, an operator who is on the upper carrier 50 operates the carrier operating device 54 to set the reference floor n as the target landing floor.

  The transporter control unit 55 of the upper transporter 50 sets the reference floor n as the target landing floor of the upper transporter 50 in the transporter control unit 55 of the lower transporter 51 and the partitioning device control unit 65 of the partitioning device 60. Send that.

  First, the partition plate 61 moves to the position P <b> 1 where the shock absorber 64 of the partition device 60 does not come into contact with the upper carrier 50 even when the upper carrier 50 reaches the reference floor n. The position P1 is determined in advance. The partition control unit 65 and the transporter control units 55 of the upper and lower transporters 50 and 51 include information on the position P1.

  Further, the movement range of the lower carrier 51 is limited so as not to go beyond the position where it does not contact the shock absorber 64 of the partition device 60. In the present embodiment, the movement is limited only to the first basement floor, which is the floor immediately before the reference floor n, and the movement below this floor.

  When the partition plate 61 moves to the position P1, the partition device control unit 65 transmits the fact that the partition plate 61 has moved to the position P1 to the transporter control unit 55 of the upper transporter 50. When the transporter controller 55 of the upper transporter 50 confirms that the partition device 60 has moved to the position P1, that is, when the above signal is received, the transporter motor 57 is controlled to attach the upper transporter 50 to the reference floor n. To floor.

  When the work such as loading or unloading of the luggage to / from the upper carrier 50 is completed and the carrier operating device 54 of the upper carrier 50 is operated to leave the upper carrier 50 reference floor n, the carrier controller 55 of the upper carrier 50 Then, the fact that the upper carrier 50 leaves the reference floor n is transmitted to the partition device controller 65 and the carrier controller 55 of the lower carrier 51. When the upper carrier 50 is separated from the reference floor n, the lower carrier 51 can land on the reference floor n.

  The same applies to the case where the lower carrier 51 reaches the reference floor n. In this case, the partition device 60 moves to a position P2 indicated by a two-dot chain line in FIG. The position P <b> 2 is a position where the lower transporter 51 does not contact the shock absorber 64 of the partition device 60 when the lower transporter 51 reaches the reference floor n. Then, the movement of the upper carrier 50 is limited only to the second floor, which is the floor immediately before the reference floor n, and the floor above the floor. In this way, the partition plate 61 moves between the first and second positions P1, P2. The partition device control unit 65 and the transporter control units 55 of the upper and lower transporters 50 and 51 include information on the position P2.

  The partition device control unit 65 of the partition device 60, the transport device control unit 55 of the upper transport device 50, and the transport device control unit 55 of the lower transport device 51 exchange position information with each other. For this reason, each position is grasped. Specifically, the partition device controller 65 grasps the position of the upper carrier 50 and the position of the lower carrier 51. The transporter controller 55 of the upper transporter 50 grasps the position of the partition device 60 and the position of the lower transporter 51.

  In FIG. 13, the post 20 is supported in the first direction A by the base 23, and the pins 133 and 144 of the first and second coupling devices 130 and 140 are the post 20 and the frame 81, and the post 20 and the slide. FIG. 10 is a front view showing the first portion 101 in a state where the portion 103 is not connected to the first direction A.

  FIG. 14 is a schematic view showing the post side pin hole 136, the slide part side pin hole 145, and the frame side pin hole 139. FIG. 14A shows the post side pin hole 136, the slide part side pin hole 145, and the frame side pin hole 139 in the state shown in FIG. In the state shown in FIG. 14A, as an example, the slide part side pin hole 145 overlaps the center of the post side pin hole 136. The frame side pin hole 139 overlaps the lower part of the post side pin hole 136.

  When reverse climbing is performed, first, the post unit 21 is connected to the upper end of the post 20 as shown in FIG. Next, the cylinder driving motor 113 is operated by operating the climbing device operating device 120 to raise the slide portion 103. Then, as shown in FIG. 14B, the slide portion 103 is aligned with the position where the slide portion side pin hole 145 overlaps the center of the post side pin hole 136 in the vicinity of the uppermost end position. The reason why the slide part side pin hole 145 is aligned with the position overlapping the center of the post side pin hole 136 is to insert the pin 144 into the slide part side pin hole 145 smoothly. As long as the pin 144 can be smoothly inserted into the slide part side pin hole 145, the slide part side pin hole 145 may not overlap the center of the post side pin hole 136 in the first direction A.

  Next, as shown in FIG. 14C, the pin 144 is inserted into the slide portion side pin hole 145 and the post side pin hole 136. Next, the operating device 120 is operated to raise the slide portion 103 to a position where the load of the post 20 is applied to the edge of the slide portion side pin hole 145 via the pin 144 as shown in FIG. Next, the base outrigger 32 is shrunk so that the base outrigger 32 does not rest on the floor 6. As a result, the support of the post 20 by the outrigger 32 is released, so that the post 20 is supported only by the slide portion 103.

  Next, the operating device 120 is controlled to lower the slide portion 103. As the slide part 103 is lowered, the post 20 is lowered. FIG. 15 shows a state where the slide portion 103 is lowered.

  FIG. 14E shows a state in which the slide portion 103 is lowered to a position where the slide portion 103 is near the lowermost position of the slide portion 103 and the frame side pin hole 139 overlaps the center of the post side pin hole 136. Yes. When the slide unit 103 is lowered to this position, the operation device 120 is operated and the movement of the slide unit 103 is stopped. The frame side pin hole 139 is aligned with the position overlapping the center of the post side pin hole 136 in order to smoothly insert the pin 133 into the frame side pin hole 139. If the pins 133 can be smoothly inserted into the frame side pin holes 139, the frame side pin holes 139 do not have to be overlapped with the center of the post side pin holes 136.

  Next, as shown in FIG. 14 (f), the operation lever 135 of the first coupling device 130 is operated to insert the pin 133 into the frame side pin hole 139 and the post side pin hole 136. FIG. 16 shows the first portion 101 corresponding to FIG.

  Next, as shown in FIG. 14G, the operating device 120 is controlled so that the slide portion 103 is slightly lowered so that the load of the post 20 is applied to the edge of the frame side pin hole 139 via the pin 133. In this embodiment, the slide part 103 is lowered to the lowest end position. Next, the operating device 120 is operated so that the slide portion side pin hole 145 overlaps the center of the post side pin hole 136. In the present embodiment, when the slide part 103 is lowered to the lowermost position, the slide part side pin hole 145 overlaps the center of the post side pin hole 136, so that the slide part side pin hole 145 overlaps the center of the post side pin hole 136. Thus, the operation of moving the slide portion 103 is unnecessary.

  Next, as shown in FIG. 14 (h), the pin 144 is pulled out. Thus, the post 20 is supported by the frame 81 at the lowered position. Next, as shown in FIG. 14 (i), the slide portion 103 is raised to a position where the slide portion side pin hole 145 overlaps the center of the post side pin hole 136 in the vicinity of the uppermost end. Next, the pin 144 is inserted.

  Next, as shown in FIG. 14J, in order to receive the load of the post 20 at the edge of the slide part side pin hole 145 via the pin 144, the operating device 120 is operated to slightly raise the slide part 103. At this time, since the post-side pin hole 136 has a long hole shape in the first direction A, the load of the post 20 applied to the frame 81 via the pin 133 is released.

  Next, as shown in FIG. 14 (k), the post unit 21 is connected to the upper end of the post 20. Next, as shown in FIG. 14D, the pin 133 is pulled out. Thereafter, the post 20 descends by repeating the operations of FIGS. 14D to 14K.

  In the climbing operation for raising the post 20, the load of the post 20 is alternately applied to the frame 81 and the slide portion 103 by the insertion and extraction of the pins 133 and 145 and the movement of the slide portion 103, as in the reverse climbing operation described above. In addition, the post 20 is moved up by moving the slide portion 103.

  In the elevator apparatus 10a configured as described above, the same effects as those of the first embodiment can be obtained. Further, since the partition device 80 includes the frame 81, the partition plate 82 contacts the first and second contact portions 83 and 84. Thus, even if the partition device 80 contacts the upper carrier 50 and is urged downward by a load input from the upper carrier 50, it does not fall below the second position P2. Furthermore, when it falls to the 2nd position P2, the urging | biasing force input from the upper side carrying device 50 is transmitted to the building 5 via the flame | frame 81. FIG. In other words, the urging force input from the upper carrier 50 can be supported by the building 5 by using the frame 81.

  Further, since the climbing device 100 has a structure using the frame 81 of the partition device 80, the number of components of the climbing device 100 can be reduced.

  When the post 20 is reverse-climbed, the load of the post 20 is supported by the building 5 through the frame 81 by the first connecting device 130 or the second connecting device 140.

  For this reason, since the load of the post 20 is not received on the ground 1, the post 20 can be reverse-climbed immediately even after the lower floor is formed. This point will be specifically described.

  When the frame 81 is not present, when the post 20 is reverse-climbed, the post 20 is temporarily lowered until it contacts the ground 1 so that the load of the post 20 is supported by the ground 1, and then the base outrigger 32 is It is necessary to adjust so as to be placed on the floor portion 6 so that the load of the post 20 is supported by any of the floor portions 6.

  The ground 1 needs to be maintained so that the load of the post 20 can be supported, and time for maintaining the ground 1 is required. For this reason, the post 20 cannot be lowered until the maintenance of the ground 1 is completed.

  However, in the present embodiment, when the post 20 is reverse-climbed, the load of the post 20 is supported by the building 5 via the frame 81, so it is not necessary to support the post 20 by the ground 1. In other words, since it is not necessary to maintain the ground 1, the post 20 can be lowered immediately.

  In the present embodiment, since the post 20 is lengthened when climbing or reverse climbing, the length of the rail 28 changes accordingly. For this reason, the position of the partition plate 82 with respect to the rail 28 and the positions of the upper and lower carriers 50 and 51 change. The partition device control unit 65 and the transport device control unit 55 of the upper and lower transporters 50 and 51 update the length of the rail 28, whereby the partition plate 82 for the rail 28 and the upper and lower transport devices 50. , 51 position information is updated. Thus, the partition device controller 65 can accurately detect the position of the partition plate 82 even if the length of the rail 28 changes. The transporter control unit 55 of the upper transporter 50 can detect on which floor of the building 5 the upper transporter 50 is located. The transporter control unit 55 of the lower transporter 51 can detect on which floor of the building 5 the lower transporter 51 is located.

  In the first and second embodiments, two posts 20 are used. However, the number of posts 20 is not limited. For example, the number of posts 20 may be one.

  In the first and second embodiments, the upper carrier 50 and the lower carrier 51 are used as an example of a plurality of carriers. However, it is not limited to using two carriers. For example, you may use other multiple, such as three or four carriers. In this case, the partition device 60 described in the first embodiment or the partition device 80 described in the second embodiment is provided between a pair of adjacent carriers along the rail, whereby the first The same effect as that of the embodiment or the same effect as that of the second embodiment can be obtained.

  In the first embodiment, the partition plate 61 of the partition device 60 covers the entire lower carrier 51 in the first direction A. In the second embodiment, the partition plate 82 of the partition device 80 covers the entire lower carrier 51 in the first direction A. However, it is not limited to covering the whole. The same effect can be obtained by covering at least a part. More preferably, if the whole is covered as described in the first and second embodiments, it is possible to further suppress the fallen object from the upper transporter 50 from hitting the lower transporter 51.

  Further, the post-side pin hole 136 is a long hole in the present embodiment. However, the post-side pin hole 136 is, as in the case of the frame-side pin hole 139 and the slide part-side pin hole 145, a clearance that allows the pins 133 and 145 to be inserted into and extracted from the cross-sectional shape of the pins 133 and 145. It may be a large circle.

Further, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, you may delete some components from all the components shown by embodiment mentioned above. Furthermore, you may combine the component covering different embodiment suitably.
