EXAMPLES Examples of the present invention will be described below. FIG. 1 is a front view of a rotary parking apparatus according to the present invention,
FIG. 2 shows a side view thereof, in which 1 is a basket-shaped drum rotatably mounted on support rollers 3 and 3 provided on the machine frame 2, and four vehicle-loading gondolas 4, 4 and 4 are provided. , 4 are hung at equal intervals.

As shown in FIGS. 2 and 3, the basket-shaped drum 1 includes a roller rail 5 made by bending an H-shaped steel engaging with the supporting roller 3 and a pin rack which meshes with a drive sprocket 6. It is composed of front and rear rims 8 and 8 provided with 7, and four connecting rods 9, 9, 9, 9 which connect the rims 8 and 8, and the storage cage 4 is attached to the connecting rod 9. . In the embodiment, the connecting rod is adapted to rotate.

In order to prevent smooth rotation and deviation of the basket-shaped drum 1, holding rollers 10 engaging with the roller rails 5 are provided at four positions on the upper portion of the machine frame 2, and a reduction gear is driven by a motor 11. Device 12, Chain 1
3, driven by the chain wheel 14 and the drive sprocket 6.

The rear rim 8 is configured to be driven together with the rim 8 by transmitting the rotation of the reduction gear unit 12 through the interlocking shaft 15, the chain and a drive sprocket (not shown).

Further, the manual handle 16 is rotated to move the pin rack 7 through the chain 17 and the chain wheel 18.
The cage drum 1 can be manually rotated by rotating the drive sprocket 19 that engages with.

To stop the basket-shaped drum 1, when a stop switch (not shown) is pressed, when a dog (not shown) provided on the rim 8 operates the fixed position stop limit switch 20, the disc brake device is activated. The storage cage 4 is designed to stop when the rim 8 is restrained and moved to the right from the lowest position as shown in FIG.

(Horizontal runout preventing mechanism of storage cage) In the present embodiment, a ring-shaped steadying guide rail 22 is arranged at the rear portion of the basket drum 1, and as shown in FIG. At the lower part of each back surface, a steadying roller 23 having an outer diameter smaller than the inner width of the recess of the guide rail 22 engaging with the guide rail 22 is provided so as to project rearward.

The steadying roller 23 can be mounted vertically by using the mounting hole 24 as a long hole. Normally, as shown in FIG. 5, when the storage cage 4 is at the uppermost position,
The roller 23 is set close to the inner edge 22a of the guide rail 22. That is, the locus of the center position of the steadying roller is deviated downward from the center circle CC2 of the guide rail 22. However, it goes without saying that it may be set so as to contact the outer edge 22b.

In the embodiment, the inner width of the concave portion of the guide rail 22 is made larger than the outer diameter of the roller 23 so that the roller 23 can smoothly move in the guide rail 22. Therefore, as shown in FIG. 5, a spacer 25 is attached in the guide rail at the stop position to narrow the passage, and the lateral shake at the stop position is not felt by the human body at the stop position.

Further, when the roller 23 is set as described above, when the storage cage 4 reaches the uppermost position and the lowermost position, the position of the roller 23 is slightly lowered, and the movement may be deteriorated. . Therefore, in the embodiment, the guide rail 22 is provided with pockets 26, 26 (relief) as shown in FIG. In FIG. 1 and FIG. 2, 27 is a roller provided on the lower front surface of each storage cage 4, which engages with the recess 28a of the pedestal 28 provided at the stop position to allow the storage cage 4 to move in and out. It is designed to reduce the fluctuations before and after.

Since the procedure for entering and leaving the rotary parking system is not much different from that of the conventional rotary parking system, the description thereof will be omitted here. Instead, many features and effects of this configuration will be described.

【The invention's effect】

B) The two-stage small-scale parking system that is widely used is
Most of the cantilever type pallets are raised and lowered by chains or wire ropes, but there is a risk of cutting and dropping accidents, and in the event of a typhoon etc., there is an increased risk of falling accidents due to shaking and cutting. On the other hand, the present invention is highly safe because it is a member that should be considered for cutting and is not lifted. In the event of a typhoon, once the brakes are released and the center of gravity is automatically stabilized, you can feel secure not only when you have four cars but also when you have three or less. B) The embodiment is for outdoor use, but if the structure of the machine frame is changed, a semi-underground parking device (in this case, the car will enter and exit from the upper storage cage) and a parking device facing the slope road Can be provided. C) It is difficult to manually operate the widely-used valet-lifting type at the time of power failure or disaster, but since the present invention is a rotating drum type, it can be operated manually and can respond to disasters. . D) The recess width of the guide rail 22 is configured to be larger than the outer diameter of the steady rest roller 23, and the mounting position of the roller 23 is displaced inward or outward from the center circle CC2 of the guide rail 22. Therefore, it is possible to smoothly and cyclically move, and at the same time, it is possible to reduce swinging during movement. (E) Since the passage of the guide rail 22 at the stop position is formed to be narrow, it is possible to make it small enough not to feel any anxiety caused by swinging at the time of entering or exiting the vehicle by supporting three points at the time of stop. V) It is possible to provide a structure which is simpler in structure than other rocking prevention mechanisms and therefore easy to manufacture, and which has a reliable function and is robust. G) With the exception of the large-sized tower type, the conventional parking system requires temporary operations such as temporary evacuation or sequential feeding when the vehicle near the entrance gets in the way when entering and exiting, but the main beam is instantly and freely available. Can be loaded and unloaded. H) Because of the rim and support roller system, the tolerance of the knitting core of a large-diameter rotating device is large, which is a great advantage in terms of manufacturing and durability.
