Description

  Embodiments of the present invention relate to a conveyor device used as an escalator, a moving walkway, and the like.

  A conveyor device used as an escalator or a moving sidewalk forms a moving path that circulates and moves in a predetermined direction by connecting a plurality of steps endlessly with a chain or the like. When the conveyor device is an escalator, such a moving path drive mechanism is configured by rotating a sprocket provided below the boarding board at the upper floor entrance and exit through a speed reducer by a motor arranged in the machine room. The endless moving path described above is circulated and moved.

  In this case, a separate machine room is required to accommodate the drive mechanism. Further, since a V-belt and a drive chain are interposed between the motor and the sprocket, it is difficult to make the drive mechanism compact, so that space efficiency is poor and transmission efficiency is low. In addition, there are many articles that require maintenance such as V-belts and chains, and the maintenance and management thereof are difficult.

It is a figure which shows the further another structural example of the torque transmission frame used for one Embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  First, the overall structure of the conveyor apparatus according to this embodiment will be schematically described with reference to FIG. As shown in FIG. 1, the conveyor device (referred to as an escalator) is configured in a truss 1 installed between a lower floor and an upper floor of a building. This escalator has a moving path 2 that circulates and moves by connecting a plurality of steps in an endless manner. A pair of left and right balustrades 4 are provided on both sides of the upper end of the endlessly configured moving path 2, and a moving handrail 5 is wound around the balustrade 4 to circulate in a predetermined circulation path.

  The moving path 2 is configured by connecting a plurality of steps in an endless manner with a step chain as described above. This step chain is stretched between a step sprocket 9 disposed below the boarding board at the upper floor entrance and a step sprocket 10 disposed below the board at the lower floor boarding board. Of these, the upper step sprocket 9 is rotationally driven via a speed reducer by a driving motor described later. When the step sprocket 9 is driven to rotate, the step chain circulates and the moving path 2 also circulates. Accordingly, the upper floor step sprocket 9 functions as a drive wheel of the moving path 2.

  The truss 1 described above is provided along the length direction of the moving path 2 that circulates, and the first support body 11 and the second support body 12 (shown in FIG. 2) located on both sides of the moving path 2. ). As shown in FIG. 2, the rotational drive mechanism 20 of the drive wheel 9 is compactly configured between the first support body 11 and the second support body 12.

  The rotational drive mechanism 20 is configured such that a plurality of components including a driving motor 21 are linearly arranged along the rotational axis direction of the motor 21 and are integrally connected by a connecting body 25. A plurality of components of the rotary drive mechanism 20 includes a motor 21 and a flywheel 22 integrally attached to one of the rotation shafts (the lower side in FIG. 2), and the other of the rotation shafts (the upper side in FIG. 2). The coupling brake 23 and the speed reducer 24 are provided. The plurality of components 21, 22, 23, 24 are integrally connected by a connecting body 25 penetrating them.

  The rotation driving mechanism 20 connected by the connecting body 25 is connected so that the connecting direction is orthogonal to the moving direction (X direction in the drawing) of the moving path 2 between the first support body 11 and the second support body 12. Be placed. One end (lower end in FIG. 2) 20a is fixed to and supported by the first support 11. Further, the tip of the rotation drive shaft 26 led out from the other end (upper end in FIG. 2) 20 b of the rotation drive mechanism 20 is rotatably attached to the second support 12 via a bearing 27.

  The upper floor step sprocket 9 (drive wheel) and the lower floor step sprocket 10 described above are each composed of a pair of sprockets disposed on both sides of the moving path 2. Of these, regarding the step sprocket 9 on the upper floor (hereinafter referred to as drive wheel 9), the drive wheel 9 is disposed on both sides (upper and lower sides in the drawing) of the rotary drive mechanism 20, as shown in FIG. The first drive wheel 91 and the second drive wheel 92 are also included. These first drive wheel 91 and second drive wheel 92 are wound with step chains that connect both end portions of the moving path 2 in an endless manner, and are moved by the rotation. The path 2 is circulated.

The first drive wheel 91 is attached to the rotary drive shaft 26 near the second support 12 and rotates integrally with the rotary drive shaft 26 to drive one side of the moving path 2. The second drive wheel 92 is rotatably disposed on the outer periphery of the rotation drive mechanism 20 near the first support 11 via a bearing 28 and drives the other side of the moving path 2.
The first drive wheel 91 and the second drive wheel 92 rotate integrally through the torque transmission frame 31. That is, the torque transmission frame 31 is disposed along the outer periphery of the rotary drive mechanism 20, integrally connects the first drive wheel 91 and the second drive wheel 92, and is formed on the outer surface of the rotary drive mechanism 20. At least a part of it is open to the outside.

  As the torque transmission frame 31, for example, a plurality of rod-shaped materials 311 are used as shown in FIG. Then, both end portions in the length direction of these rod-shaped members 311 are integrally coupled to corresponding ones of the first driving wheel 91 and the second driving wheel 92. Further, these rod-shaped members 311 are spaced outward from the outer peripheral surface of the rotary drive mechanism 20 and are arranged in parallel along the outer peripheral surface with a space therebetween.

  By using the plurality of rod-shaped members 311 as the torque transmission frame 31, at least a part of the outer surface of the rotation drive mechanism 20 (the outer surface facing the interval between the plurality of rod-shaped bodies 311) is open to the outside as described above. Thus, inspection and adjustment work for the rotary drive mechanism 20 from the outside is facilitated. Further, the cooling air can be taken into the rotation drive mechanism 20.

  As described above, the connecting body 25 penetrates and integrally connects the plurality of components 21, 22, 23, 24. However, the connecting body 25 does not need to be integrated. That is, the bolt-like members 251 and 252 inserted in abutting manner through the corresponding ones of the components 21, 22, 23 and 24 from both ends (upper and lower sides in FIG. 2) of the rotary drive mechanism 20 are used. That's fine. The front ends of the bolt-shaped members 251 and 252 are integrated by screwing into an intermediate portion of the rotational drive mechanism 20, for example, a collar member 32 disposed between the coupling brake 23 and the speed reducer 24 as shown in FIG. To be configured. If comprised in this way, the connection body 25 can be arbitrarily isolate | separated in the intermediate part, The check adjustment work of the rotation drive mechanism 20, etc. will become easy.

  In the above configuration, by operating the motor 21 which is a component of the rotation drive mechanism 20, the rotation is transmitted to the flywheel 22, and is also transmitted to the speed reducer 24 via the coupling brake 23, so that a predetermined rotation is achieved. The rotational drive shaft 26 is rotated at a reduced speed. Since the rotary drive shaft 26 is integrally attached with the first drive wheel 91, the first drive wheel 91 is rotated at a predetermined rotational speed. Further, since the first drive wheel 91 is integrally connected to the second drive wheel 92 by the torque transmission frame 31, the second drive wheel 92 also rotates at the same speed together with the first drive wheel 91.

  Since the first drive wheel 91 and the second drive wheel 92 are respectively wound with step chains that connect both end portions of the moving path 2 in an endless manner, the first drive wheel 91 and the second drive wheel 92 are wound around each other. As the driving wheel 92 rotates, the moving path 2 is driven to circulate in a predetermined direction.

  Here, since the rotational drive mechanism 20 is compactly configured between the first support body 11 and the second support body 12 constituting the truss 1, it is not necessary to provide a separate machine room as in the prior art. . In addition, since no V belt or chain is interposed between the driving motor 21 and the first driving wheel 91 and the second driving wheel 92, the driving mechanism can be made compact, space efficiency and transmission can be achieved. Efficiency is improved. Further, since there is no need for maintenance such as a V-belt or a chain, the maintainability is improved, and further, problems due to these slips and breaks do not occur.

  The periphery of the rotational drive mechanism 20 is surrounded by a torque transmission frame 31. The torque transmission frame 31 has a structure that opens at least a part of the outer surface of the rotational drive mechanism 20 to the outside, so that the rotational drive from the outside is performed. Inspection and adjustment operations for the mechanism 20 are easy, and cooling air can be taken into the rotary drive mechanism 20.

  In the above-described embodiment, as the torque transmission frame 31, a plurality of rod-like bodies 311 are arranged in parallel at intervals, and both ends thereof correspond to the first driving wheel 91 and the second driving wheel 92. However, the present invention is not limited to such a configuration. For example, as shown in FIG. 3, as shown in FIG. 4, a cover member 312 that surrounds the outer periphery of the rotary drive mechanism 20 except for a portion requiring inspection and a portion serving as a cooling air inlet, as shown in FIG. 4. Alternatively, a plurality of rod-shaped members 311 arranged in parallel may be attached.

  If comprised in this way, since the reduction gear 24 and the motor 21 part are covered with the cover member 312, the noise transmitted to the exterior can be reduced. Further, since the coupling brake 23 portion requiring inspection and adjustment is open to the outside, the inspection and adjustment can be easily performed, and the cooling air can be taken in. That is, the cover member 312 surrounds the rotational drive mechanism 20 except for a portion requiring inspection and a portion serving as a cooling air inlet.

  The torque transmission frame 31 may further have a shape shown in FIG. That is, a plurality of plate-like members 313 whose cross sections are arcuate are used. The plurality of plate-like members 313 are integrally coupled to the corresponding ones of the first drive wheel 91 and the second drive wheel 92 at both ends in the length direction. The plurality of plate-like members 313 are spaced outward from the outer peripheral surface of the rotation drive mechanism 20 and are arranged in parallel along the outer peripheral surface at intervals.

  Even if comprised in this way, while being able to reduce the noise transmitted to the exterior from the rotational drive mechanism 20, while being able to perform the inspection adjustment from the outside easily, taking in of the cooling air is also possible.

  Although several embodiments of the present invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
