Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides a method for storing a vehicle by circularly moving a large number of vehicle-mounted cages. Lift the chassis from the ground and rotate the chassis,
The present invention relates to an improvement in a circulating mobile parking facility that allows vehicles to be always driven forward from the chassis.

(Prior Art) The present applicant previously disclosed a circulating mobile parking facility of the type described above in Japanese Patent Application Laid-Open No. 58-178760. This parking facility is equipped with a movable elevating and rotating device in the pit below the vehicle entry area, and this movable elevating and rotating device moves in the direction of circular movement of the cage (i.e., in the direction perpendicular to the vehicle entry direction). a pair of front and rear carts that can be moved up and down, an elevating frame attached to the cart so that it can be raised and lowered by an appropriate elevating device, a revolving frame that is rotatably supported on the elevating frame about a vertical axis, and the vertical axis edge is the center of the cage. A cage position detector is provided on the trolley in order to match the above-mentioned height, and a cage frame fixing device is attached to the trolley in order to fix and hold the cage frame prior to raising the elevating frame.

To explain the platform turning operation in this conventional parking equipment, the original position of the platform is well shifted to one side from the center of the vehicle entry area, and two actuating cylinders are installed for each platform on the pit floor. Due to the synchronous drive of the two carriages, the lifting frame, etc. move toward the center of the vehicle entry area.

During this movement, the limit switch of the cage position detector engages with the lower side of the cage frame of the cage stopped at the vehicle entry area, thereby stopping the movement of the cart, etc. Next, the cage frame fixing device is operated to integrate the cart and the cage frame. In this state, the elevating frame will rise,
During the ascent, the upper surface of the revolving frame comes into contact with the lower surface of the vehicle chassis, and the vehicle chassis is lifted upward from the lower part of the cage frame. Then, the direction of the chassis and the vehicle on the chassis is changed 180' by turning the revolving frame 180 degrees, and then the chassis is placed on the lower part of the cage frame by lowering the elevating frame, and then the vehicle is driven forward from the cage to the entrance/exit. The vehicle departs towards the destination and completes the delivery.

(Problems to be Solved by the Invention) The above-mentioned chassis turning operation can be summarized as: moving the chassis, detecting the cage frame, fixing the cage frame and the chassis, raising the elevating frame,
It consists of sequential operations such as rotation of the revolving frame and lowering of the elevating frame.

The large number of individual movements required for chassis turning operation not only requires many drive sources and detectors, resulting in high equipment costs and a complex structure, but also requires a lot of effort to link them together. This means that the control becomes complicated and it takes a long time to turn the vehicle platform. Furthermore, since the movement of the cart is stopped upon detection of the cage frame, in order to improve the positioning accuracy of the cart, the moving speed of the cart must be slowed down or the cart must be stopped suddenly. This sudden stop of the truck causes vibrations in the lifting frame and the rotating frame, which has an adverse effect on these structures. Furthermore, in order to improve the positioning accuracy of the cart, it is better to install a drive source such as an operating cylinder on the pit floor rather than making the cart self-propelled.
Installing the drive source on the pit floor increases the amount of on-site noise and equipment costs.

(Means for Solving Problems) The movable elevating and rotating device employed in the circulation mobile parking facility of the present invention is spaced apart from the front and rear of the vehicle entry direction, and is movable in the left and right directions perpendicular to the vehicle entry direction. It can be raised and lowered by a pair of carts installed in the pit on the ground floor, vertical fixed guide cylinders installed at the left and right ends of each cart, and a lifting screw mechanism linked between the fixed guide cylinders. an elevating cylinder fitted into the fixed guide cylinder, an elevating drive mechanism that is linked to each of the elevating screw mechanisms and raises and lowers the elevating cylinder in the same elevating direction and at the same speed, and front, rear, left and right parts. a horizontal elevating frame integrally fixed to the elevating cylinder; a circular rotating body supported at the center of the elevating frame so as to be horizontally rotatable about a vertical axis; a revolving frame that comes into contact with the lower surface of the vehicle chassis when the frame is raised and lifts the vehicle chassis upward from the bottom of the cage frame; a rotational drive mechanism linked between the circular rotating body and the elevating frame; The carriage positioning and fixing device is installed on at least one of the carriages in order to determine and fix the carriage relative to the cage frame prior to operation.

(Function) When the desired unloading cage reaches the lowest vehicle entry location and stops, first, the trolley positioning and fixing device is operated to position and fix the trolley relative to the cage frame. At this time, the cart itself has a drive source for movement, and only the cart moves left and right relative to the heavy cage during positioning. Therefore, even if the cage shakes to some extent, the cart follows, and the relative positional relationship between the cage and the cart remains unchanged. Next, by the operation of the elevating drive mechanism, the elevating cylinder body rises using the fixed guide cylinder as a guide, and accordingly, the elevating frame and the rotating frame rise together. During this upward movement, the upper surface of the abutment plate of the revolving frame collides with the lower surface of the vehicle chassis, and as the frame further rises, the vehicle chassis and the vehicle mounted on the chassis are lifted upward from the lower part of the cage frame. Then, by the 180° rotation of the rotating frame, the chassis etc. are rotated 180°, and the front part of the loaded vehicle faces the entrance/exit. In this state, the elevating frame and the rotating frame are lowered, and the vehicle platform is again placed on the lower part of the cage frame. Finally, the operation of the trolley positioning and fixing device is released, and then the driver gets into the vehicle and drives forward to exit from the cage through the entrance and exit, completing the exit.

(2) Next, the elevating drive mechanism 47 operates. Simultaneously with the release of the brake of the brake-equipped speed reducer 50, the motor 49 is driven, and the endless chain 252 circulates in one predetermined direction. As a result, the sprockets 32, 37, 38, and 39 are rotated in the same direction and at the same speed, and the elevating cylinder bodies 23, 24, 25, and 26 are rotated through the ball screw mechanisms 27 to 30, respectively.
Climb at the same speed using 20, 21, and 22 as guides. Therefore, the elevating frame 40 rises while remaining in a horizontal state. During this upward movement, the two positioning pins 46b, 46b on the rotating frame 46 fit into the two hole members 7g on the lower surface of the chassis 7d, and the rotating frame 46 is positioned relative to the chassis 7d. As the elevating frame 40 further rises, the four contact plates 46a on the rotating frame 46 move to the chassis 7d.
It collides with the lower contact plate 7f and lifts the chassis 7d. Then, when the hole member 7e2 separates upward from the positioning pin 7e1 on the cage frame 7b side and the inverted-shaped contact plate 7d2 completely separates upward from the cage frame lower part 7bl, 1jii
The rising motion of the rising motion is stopped.

(3) Subsequently, the rotational drive mechanism 54 is activated. Simultaneously with the release of the brake of the brake-equipped speed reducer 57, the motor 56 is driven, and the endless chino 59 circulates in the counterclockwise direction in FIG. At this time, one part of the endless chino 59 is fixed to the circular track 45d by the fastener 61, so that the circular rotating body 45° rotating frame 46. The chassis 7d and the mounted vehicle W rotate together in a counterclockwise direction around the vertical axis. Then, just after turning 180 degrees, the motor 56 stops driving. The front part of the loaded vehicle W is now in a state pointing rearward, that is, toward the entrance/exit 9 (see FIG. 7).

(4) Then, the elevating drive mechanism 47 operates again. As the motor 49 is driven in the opposite direction, the lifting frame 40. Swivel frame 46. The chassis 7d and the loaded vehicle W are lowered together. During this descent, the hole member 7e
z and the positioning pin 7e1 are fitted and engaged, and the chassis 7d is positioned and placed on the cage frame lower part 7bl again.

(5) Thereafter, the movable plate 70 and the driven roller 74 move forward due to the shortening operation of the Ron door 2a of the operating cylinder 72, the beating roller 74 is completely detached from the positioning member 75 forward, and the bogie positioning and fixing device 62 is activated. Release.

(6) The left and right moving decks 76 and 77 operate, and the left and right decks 78 and 78 move in left and right opposite directions, and both decks 78 and 78 are placed on surfaces close to the left and right sides of the chassis 7d. Stops in one state.

(7) Finally, the door 83 opens, the driver enters the tower through the entrance/exit 9, gets into the vehicle W through the deck 78, and, by driving the vehicle W forward, exits the entrance/exit 9 from the cage 7 via the ground floor 11. Exit outside. After the vehicle W leaves the garage, the door 83 is closed again.

Incidentally, at the time of storage, the movable elevating and rotating bag fiff12 is not operated at all, and only the movable decks 76 and 77 need be driven. Of course, the movable decks 76 and 77 may be of a vertically swinging type, or may be fixed decks 176 and 177 as shown by two-dot chain lines in FIG. . Furthermore, the aforementioned bogie positioning and fixing device 62 may also be installed on the front bogie 13.
