Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking device, and more particularly to a traverse device for a mechanical parking device.

[0002]

2. Description of the Related Art With the development of motorization, the shortage of parking lots has been greatly highlighted, and in particular, there is a demand for the maintenance of large-scale parking lots in urban areas, and various mechanical parking devices have been proposed and manufactured in the past. . FIG. 4 is a partial plan view of a mechanical parking device called a horizontal circulation parking device, in which a plurality of pallets 1 on which a vehicle is placed are arranged horizontally, and along a rail 2 a horizontal direction (X direction in the drawing) and a vertical direction. The vehicle moves in the direction (Y direction in the figure) so that the vehicle can be loaded and unloaded from a predetermined position. On the lower surface of the pallet 1, traveling wheels 3 corresponding to the horizontal direction and the vertical direction and a moving fitting 4 extending in the X direction are provided.

The register mark mechanism 5 shown in FIG. 4 is a kind of lateral feed device and is widely used in mechanical parking devices. The register mark mechanism 5 includes a long arm 6 having rollers 6a at both ends.
The rollers 6a at both ends are sandwiched between the moving metal fittings 4 (comprising parallel plates spaced apart) of the adjacent pallets 1. When the register mark arm 6 is rotated, one roller 6a is disengaged from the moving metal fitting 4 of the front pallet, and the other roller 6a pushes the moving metal fitting 4 of the rear pallet forward (moving direction) to laterally move the pallet. The other pallets are connected by an appropriate engaging metal fitting 1a and integrally move laterally. Further, in FIG. 4, the vertical feeding device comprises a plurality of pairs of friction rollers 7. By sandwiching and moving the moving metal fittings 4 with the friction rollers 7, the pallets 1 at both ends can be vertically moved one by one. .

Such a horizontal circulation type parking apparatus is usually installed in the basement in a stack of 2 to 3 layers, and the horizontal movement and the vertical movement are sequentially repeated to circulate the pallet horizontally, and the vehicle is moved from a predetermined position by an emelerator or the like. It is designed to be loaded and unloaded on the ground.

[0005]

However, in the register mark mechanism described above, the pallet is made to traverse by half-rotating the long register mark arm corresponding to the lateral width of the pallet.
There is a problem that a large horizontal force for traversing a plurality of pallets acts on the tip of the dragonfly arm, so that the required torque of the dragonfly arm is large, and a large horizontal force acts on the shaft for rotating the dragonfly arm.

Therefore, as illustrated in FIG. 5, the deceleration rate for turning the registration mark arm 6 is high (for example, 1 /
280) and the output shaft has a large allowable load (large capacity)
The speed reducer 8 supported by bearings is indispensable, and due to the size of the speed reducer 8, the distance H between the pallet upper surface 1b and the mounting surface 8a of the speed reducer 8 cannot be reduced (for example, at least about 660 mm or more). there were. This interval H
In the case of a two- to three-tiered parking device, the total height of the parking device is directly affected, and particularly in an underground parking device, the civil engineering cost is greatly affected.

The present invention was created to solve the above problems. That is, the object of the present invention is to significantly reduce the distance H between the mounting surface of the traversing device and the upper surface of the pallet as compared with the conventional one, and thereby to reduce the overall height of the parking device. To provide.

[0011]

According to the above-mentioned structure of the present invention, the swing arm (dragonfly arm) is horizontally fixed to the large gear, and the large gear is supported by the large diameter ring horizontally fixed to the lower mounting surface so as to be horizontally swingable. Has been done. A combination of such a large gear and a large diameter ring is a slewing ring used in a slewing seat of a crane, etc., and a large number of balls (or Roller) makes it possible to smoothly turn.

Further, since the force acting on the revolving arm is supported by the combination of the large gear and the large diameter ring (that is, the revolving ring), a large bending force does not act on the output shaft of the reduction gear, and Since a large reduction ratio can be obtained by meshing with the small gear, the reduction ratio of the reduction gear itself can be made smaller than before, so the reduction gear can be made significantly smaller, which allows the mounting surface of the traverse device and the top surface of the pallet to be reduced. The distance H between and can be reduced significantly compared to the conventional case.

The combination of the large diameter ring 12 and the large gear 14 is
A swivel ring used for a swivel seat of a crane, etc., capable of smoothly swiveling by a large number of balls (or rollers) interposed therebetween while supporting a relatively large horizontal force acting on the action portion 15 of the swivel arm 16. You can do it. It is preferable that the gear ratio between the large gear 14 and the small gear 17 is as large as possible. For example, the reduction ratio is 1/8 to 1/1.
It is preferable that the tooth number ratio be about 0, that is, about 122: 14. Further, although the large gear 14 and the small gear 17 are spur gears in FIGS. 1 and 2, the present invention is not limited to this and may be a bevel gear or another type of gear.

To fix the large-diameter ring 12 to the mounting surface 11, it is preferable to mount the large-diameter ring 12 to the floor surface (mounting surface 11) such as the basement of the building via an appropriate mount 12a as shown in FIG. 1 (B). . The turning arm 16 is attached to the large gear 14 with bolts 14a, for example.
