Abstract

(57) [Summary] (Modified) [Problem] To enable rescue and fire extinguishing work to the upper floors, an outdoor that can perform these works promptly by a special elevator that can go up and down along the building outer wall. Provision of elevator for use. A long rack (8) and a long guide rail (3) are attached to a long support (1) substantially equal to the total height of a building, and these are vertically adhered to the outer wall of the building. The worm reducer 13 driven by the power source 17 is mounted, and the pinion 12 attached to the shaft of the worm wheel 14 is engaged with the long rack 8 and rotated in the forward or reverse direction to move the riding basket 9 in the long guide. In order to be able to move up and down along the rail 3, the removable portion 3 'of the lower end of the long guide rail is removed together with the lower end portion 8' of the long rack and the riding basket 9 so that it can be mounted and operated in use. Elevator that can withstand the outdoor open weather.

Description

[Detailed description of the invention] [Technical field to which the invention belongs] Since the invention can be used for outdoor open-air, it is suitable for rescue work and fire fighting work in the event of a disaster in a high-rise building.

[Conventional technology]

 When a fire occurs in a high-rise building and fire extinguishing work or rescue work is needed, the work is now performed by using emergency stairs or by using a riding basket attached to the tip of a ladder truck. I have. Or rescue work by helicopter.

[Problems to be solved by the invention]

 When a disaster occurs in a high-rise building, emergency stairs may not be able to be evacuated.

At this time, rescue and extinguishing work by ladder truck are necessary, but the work may be difficult due to the road conditions to the site and the density of buildings nearby. Also, it takes a considerable amount of time to start work. In addition, as buildings are becoming increasingly high-rise, the ladder tip of the ladder truck may not be able to reach. Therefore, this project is an outdoor elevator designed to enable rescue and fire extinguishing work to the upper floors and to start this work in a short time without relying on helicopters.

[Means for solving the problem]

 A basket 9 driven by an electric motor or an engine is connected to the foot of the long support 1 attached to the outer wall of the building with one touch, and the power is used to raise the basket 9 along the long support 1 to each high-rise floor. In order to enable fire fighting and rescue work, and to avoid exposure to wind and snow after use, the riding basket 9 is easily removed so that it can be stored indoors.

[Embodiments of the invention]

 As shown in Fig. 1, Fig. 2, Fig. 3, and Fig. 4, a long rack 8 and a long guide rail 3 are attached to a long column 1 approximately equal to the total height of the building. A worm reducer 13 driven by an electric source 17 such as an electric motor or an engine is mounted on a riding basket 9 and a pinion 12 attached to an axis of a worm wheel 14 is attached to a long rack. In the elevator in which the riding basket 9 is moved up and down along the long guide rail 3 by being rotated in the forward or reverse direction by meshing with the long guide rail 8, the removable portion 3 ′ at the lower end of the long guide rail is elongated. It is an elevator structure which can be removed together with the lower end portion 8 'of the shaku rack and the riding basket 9, and which can withstand outdoor open-air so that it can be mounted and operated when used.

〔Example〕

 An example of the outdoor outdoor elevator of the present invention is shown in FIG. 1, FIG. 2, FIG. 3, and FIG. The long strut 1 is a simple construction that does not significantly affect the structure of the building, only fixing it to each arm on the arm protruding from the pillar of the high-rise building. The long guide rail 3 and the long rack 8 are mounted on this long support 1 in an overlapping manner. On the other hand, a worm speed reducer 13 driven by a power source 17 such as an electric motor or an engine is mounted on the riding basket 9, and a pinion 12 attached to a shaft of the worm wheel 14 is engaged with the long rack 8 so as to be forward or reverse. The basket 9 is moved up and down along the long guide rail 3 by rotating the basket 9. Since the worm speed reducer 13 is interposed between the pinion 12 and the power source 17 for this power transmission, a reverse blocking force acts on the worm wheel 14 without applying a rotation holding force to the worm 15 with a shaft, and the elevator There is no danger of the riding basket 9 falling by its own weight. Therefore, it is safe to shut down the electric motor in the event of a power outage or in the case of an engine when the clutch is disengaged. Therefore, the driver on the riding basket 9 can safely raise and lower the elevator. This rack and pinion type elevator does not need to be installed in the building. Furthermore, in order to protect the riding basket 9 from the wind and snow, it may be necessary to remove and manage the riding basket 9 so that the elevator is not used without permission. In this case, after lowering the riding basket 9 to the position of the removable portion 3 'at the lower end of the long guide rail and placing it on the transport truck on the ground, pull out several connecting taper pins 5 and remove By pulling out the insertion projection 4 of the removable portion 3 ′ at the lower end of the guide rail from the insertion groove 2 of the long support 1, the removable portion 3 ′ at the lower end of the long guide rail is converted to the lower end 8 ′ of the long rack. And, it can be cut off from the long strut 1 by a carriage together with the riding basket 9. And it can be stored inside another room. When the elevator must be operated urgently, the basket 9 on the carrier is carried under the long column, and the removable portion 3 'at the lower end of the long guide rail is elongated by simple operation reverse to the removal. The elevator can be lifted directly by attaching it to the column 1. Therefore, fire extinguishing and rescue work can be started in a short time.

When the basket 9 is always removed, only the long strut 1 is attached to the high-rise building. Since the long strut 1 is covered with a long plastic cover and is rustproofed, There is hardly anything wrong. Therefore, the long column 1 can also be installed on the front of the building, which is convenient for fire extinguishing and rescue work.

[Effect of the invention]

 Firefighting and rescue work in high-rise buildings, which had been difficult to respond in a short time, can be performed in a short time and as safely as possible. By installing piping such as an outdoor high-pressure water supply pipe in parallel with the long strut 1, it will be an effective elevator for fire-fighting work.
