Description

  The present invention relates to a rail device in an elevator that engages with a rail laid along a vertical wall surface of a structure and raises and lowers an elevator car equipped with a drive device, and includes an emergency escape escape ladder About.

Japanese Patent Application Laid-Open No. 2004-133867 discloses a wind power generator provided with a lifting device. The wind power generator assembles a steel tower on the ground and attaches a wind power generator to the tip of the steel tower, while attaching a lifting ladder to the outer surface of the steel tower and attaching a lifting device to the ladder (Patent Document 1). , FIG. 1). The lifting / lowering device 1 includes a rail attached to the ladder 5 and extending in the vertical direction, and a substantially rectangular box-shaped lifting / lowering body disposed so as to be movable up and down along the rail. The rail includes a rack extended along the rail body at a substantially central portion of the surface of the rail body having an H-shaped cross section attached to the ladder. The elevator body has a traveling portion on the back side of a rectangular box-shaped casing (elevating cage), and the traveling portion engages with the rail so as to be movable up and down.

In general, in the above-described lifting device, when the elevator car stops on the way of going up and down due to some abnormality, and the vehicle becomes unable to run, the occupant removes from the emergency exit provided on the ceiling of the elevator car. You can escape to the nearest floor step using a ladder. However, in the conventional lifting device as described above, the ladder is arranged in parallel and close to the back surface of the lifting cage (see FIGS. 1 and 6 of Patent Document 1), so that it comes out from the exit of the ceiling. Passengers can climb up the ladder and evacuate upward, but the elevator can't get down and evacuate down the ladder. This may make it difficult to evacuate depending on the stop location.
Therefore, this invention provides the rail apparatus for elevators provided with the ladder which the passenger who escaped out of the cage from the emergency exit provided in the ceiling of the elevator car can evacuate upward and downward. This is the issue.

  In order to solve the above-mentioned problem, in the present invention, the rail 3 is supported by the support member 2 at a predetermined interval from the wall surface 22 so that the lifting space S is formed between the wall surface 22 of the structure and the lifting cage 21. Support. Located in the elevating space S, the ladder support member 4 supports the escape ladder 5 on the structure. The evacuation ladder 5 is arranged in a direction in which the step bar 9 is substantially perpendicular to the wall surface 22 of the structure. The raising / lowering space S formed between the wall surface 22 of the structure and the raising / lowering car 21 is set to have a sufficient width to allow a person moving up and down the escape ladder 5 to pass in the vertical direction.

  The elevator space S is formed between the wall surface 22 of the structure and the elevator car 21, and the evacuation ladder 5 is not in close contact with the elevator car 21, and is provided in a direction orthogonal to the elevator ladder 21. When evacuating, the elevator car 21 does not become an obstacle, and therefore, the evacuation ladder 5 can be used to evacuate upward or downward without difficulty.

  Embodiments of the present invention will be described with reference to the drawings. 1 is a plan view of an elevator according to the present invention, FIG. 2 is a schematic perspective view of the elevator, FIG. 3 is a side view of a rail device according to the present invention, FIG. 4 is a sectional view taken along line IV-IV in FIG. These are VV sectional drawings in FIG.

  In the figure, the elevator 21 is provided so as to move up and down along a vertical wall surface of a structure such as a side wall 22 of a cylindrical wind power generation tower. Engaging with the rail device 1 laid along the wall surface 22, the elevating car 24 mounted with the driving device 23 moves up and down. The elevator car 24 has a rectangular box shape, and is provided with a driving device 23 on the back side, an entrance / exit (not shown) on both left and right sides, and an emergency exit 25 on the ceiling.

  The rail device 1 includes a rail support member 2, a rail 3, a ladder support member 4, and an escape ladder 5. The wall surface 22 of the wind power generation tower is curved, but may be a flat surface in relation to the elevator according to the present invention, so that it is treated as a flat surface in the following description.

  The rail support member 2 includes a pair of upright pieces 6 (6a, 6b) that stands upright from the wall surface 22, and a support piece 7 that is parallel to the wall surface 22 that connects the tips of the upright pieces 6. The rail support member 2 has a predetermined distance between the rail 7 and the wall surface 22 of the building in order to form a lifting space S large enough for a person to move up and down between the wall surface 22 of the structure and the elevator car 21. Place and support.

  The evacuation ladder 5 is located in the elevating space S formed between the wall surface 22 and the elevating cage 21 and is supported by the structure by the ladder support member 4. The escape ladder 5 is formed by connecting a pair of support columns 8 and 8 with a large number of step bars 9, and the step bars 9 are arranged in a direction substantially perpendicular to the wall surface 22.

  In the illustrated embodiment, the rail 3 includes a rail main body 10 made of an H-shaped steel material and a rack 11 fixed along the rail main body 10. The rail body 10 has one flange 10a disposed substantially parallel to the wall surface 22 and is supported on the support piece 7 of the support member 2 by a fastening metal 12 and a bolt / nut 13 at predetermined intervals in the extending direction. . The rack 11 is fixed on the other flange 10 b of the rail body 10 and extends in the vertical direction along the rail body 10. The elevator car 21 includes a pinion 26 that engages with the rack 11 and is driven to rotate.

  In the illustrated embodiment, the escape ladder 5 is supported on the flange 10a of the rail body 10 via the support arm 4 which is a ladder support member. That is, the support arm 4 is fixed to one flange 10a of the rail body 10 at one end side, extends in a horizontal direction from the rail body 10 substantially parallel to the wall surface of the structure, and the center of the step bar 9 is perpendicular to the other end side. It is penetrated and fixed to the escape ladder 5. Various other changes can be made to the means for supporting the escape ladder 5 in the elevating space S.

  With the above configuration, the passenger who has escaped from the upper exit 25 of the elevator car can escape in the upper and lower arbitrary directions by the escape ladder 5 through the elevator space S.

  The present invention is used, for example, as a rail device including an escape ladder in an elevator installed in a wind power generation tower.

It is a top view of the elevator which concerns on this invention. It is a schematic perspective view of the elevator according to the present invention. It is a side view of a rail device concerning the present invention. It is IV-IV sectional drawing in FIG. It is VV sectional drawing in FIG.
