Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to a device for hand-winding a man conveyor such as an escalator or a moving walkway, and is particularly applicable to a curved escalator, a high-height escalator, or a long moving walkway. The present invention relates to a manual winding device suitable for application to a passenger conveyor having a large running resistance.

[Prior art]

3 to 5 show conventional curved escalators. In the figures, reference numeral 1 denotes the main frame of the curved escalator, which has an arcuate shape in a horizontal projection plane and is arranged at an angle. Reference numeral 2 denotes an endless conveyance path in the main frame 1, 3 a fan-shaped plane and a large number of steps arranged in succession on the conveyance path 2, and 4 installed at an upper reversing portion position of the conveyance path 2. 5 is a motor mounting base for mounting the motor 4 on the reducer 6, and 7 is the motor 4 arranged horizontally.
8 is a V-belt pulley that is fitted onto the output shaft 7 and has a plurality of grooves formed on its circumferential surface; 9 is a hand-wound pulley attached to the outer end of the V-belt pulley 8 of the output shaft 7; a flywheel that also serves as a handle; 10 is an input shaft of the reducer 6 provided parallel to the output shaft 7;
11 is a V-belt pulley that is fitted onto the input shaft 10 and has a plurality of grooves formed on its circumferential surface; 12 is an endless V-belt pulley that is wound between the V-belt pulleys 8 and 11 to connect them; V-belt 13 is an electromagnetic brake attached to the reduction gear 6.

By starting the motor 4, the speed reducer 6 is driven, and the step 3 is driven by the output shaft (not shown) of the speed reducer 6, so that the conveyance path 2 is circulated.

By the way, when installing an escalator or performing maintenance inspection, the flywheel 9 at the end of the output shaft 7 of the motor 4 is manually rotated to perform hand-wound operation.

However, in curved escalators, high-height escalators, long moving walkways, etc., running resistance is large even when there is no passenger load. For this reason, when the flywheel 9 is directly manually rotated as in the conventional case, the required torque for manual winding operation becomes considerably large, and there are drawbacks such as that the operation is not easy.

In addition, in a drive device for a passenger conveyor having a structure in which a parallel shaft reducer and a motor are connected via a coupling, the input shaft of the reducer or the motor shaft is A manual winding device has been proposed in which a driven wheel is provided and the driven wheel is driven by the driving wheel via an endless band, but the input shaft or motor shaft does not protrude sufficiently to the side opposite to the coupling. If not, the driven wheel cannot be attached and a special structure is required.

[Summary of the idea]

This invention was made for the purpose of eliminating such drawbacks, and in a passenger conveyor in which a drive motor shaft arranged horizontally and a reduction gear input shaft parallel to this are connected via a V-belt pulley and a V-belt. A hand-wound driving shaft driven by a hand-wound handle shaft is arranged in parallel above the drive motor shaft, and a small rotary wheel is attached to this hand-wound driving shaft, and a V-belt pulley is connected to the outer flywheel at the intermediate portion thereof. A hand-wound pulley part with a larger diameter than the V-belt pulley is formed to bulge out, and an endless power transmission string is wound around this hand-wound pulley part and a small rotating ring, thereby creating a drive with a special structure. The present invention proposes a hand-winding operation device for a passenger conveyor that can perform hand-winding operation with a small force using a hand-winding handle without using a motor or a speed reducer.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIG. In the figure, the same reference numerals as those in FIGS. 3 to 5 indicate the same or corresponding parts, and 14 is a manual winding pulley part formed in a bulge at the connection part of the flywheel 9 of the V-belt pulley 8, and A groove is formed therein, and its diameter is set to be at least 1.2 times the diameter of the V-belt pulley 8. Reference numeral 15 denotes a hand-winding drive shaft which is arranged above the motor 4 and parallel to the output shaft 7 and whose one end is rotatably supported by the main frame 1; 16 is a hand-winding drive shaft facing the hand-winding pulley portion 14 of the hand-winding drive shaft 15; A small hand-winding sprocket 17 is attached to the hand-winding small sprocket 16 and has a diameter of 1/2 to 1/3 of the hand-winding pulley portion 14. An endless roller chain 18 that is wound and connects these, one end of which is horizontally connected to the other end of the manual winding drive shaft 15, and the other end of which is attached to the hand winding handle shaft 19; A handle shaft support portion 20 is horizontally fixed to the main frame 1 and rotatably supports the hand-wound handle shaft 18.

However, since the diameter ratio of the hand-winding small sprocket 16 and the hand-winding pulley part 14 is set to 1:2 to 1:3, the torque during hand-winding operation, that is, the hand-winding handle 19, can be controlled with a small force. You can expect it to turn. In addition, the manual winding pulley part 14 is a V-belt pulley 8.
Since the connecting portion of the flywheel 9 is formed with a large diameter bulge, there is no need to purposely extend the output shaft 7 of the motor 4 or the input shaft 10 of the reducer 6. There is no need for a special structure, and the downward load generated by the flywheel 9 and V-belt 12 on one side of the output shaft 7 can be absorbed by the manual winding pulley part 14 and the manual winding small sprocket 16 at the center of these 9 and 12. and roller chain 17
Since it can be supported by the output shaft 7, the load applied to the output shaft 7 can be reduced, and since the hand-wound pulley part 14 itself has a function as a flywheel, the rotation of the motor 4 can be evened out together with the flywheel 9. Furthermore, since the diameter of the hand-winding pulley portion 14 is set to be 1.2 times or more the diameter of the V-belt pulley 8, the hand-winding driving device can also be used for testing the adjuster of the speed reducer 6.

In addition, a pair of large and small V-belt pulleys or pulleys having the same diameter ratio may be used in place of the hand-winding pulley portion 14 and the hand-winding small sprocket 16, and a V-belt or timing belt may be used in place of the roller chain 17. The same effects as in the above embodiment can also be obtained.

Next, FIG. 2 shows another embodiment of the present invention, in which the same reference numerals as in FIG. They are a pair of bevel gears that are respectively fitted onto one end of a hand-wound handle shaft 18 that is vertically supported by the section 20 and mesh with each other at right angles.

However, even with this configuration, the same effects as those of the above embodiment can be expected, and since manual work can be performed from above, operability can be improved.

Note that the same effect can be obtained by using other direction changing mechanisms such as a universal joint or a flexible shaft in place of the pair of bevel gears 21a and 21b.

[Effect of idea]

As described above, the present invention provides a manual winding operation device for a passenger conveyor that can easily perform manual winding operation with a small force using a hand winding handle without using a specially structured drive motor or speed reducer. be able to.

In particular, since the hand-wound pulley part is formed with a large diameter bulge at the flywheel connection part of the V-belt pulley, there is no need to purposely extend the output shaft of the motor or the input shaft of the reducer. There is no need for the reducer to have a special structure, and the downward load generated by the flywheel and V-belt on one side of the output shaft is transferred to the manual winding pulley section in the center of these.
Since it can be supported by a small hand-winding sprocket and a roller chain, the load applied to the output shaft can be reduced, and the hand-winding pulley itself has a function as a flywheel to further equalize the rotation of the motor together with the flywheel. It has the special effect of being able to
