Abstract

PURPOSE:To shorten the time of taking vehicle out of parking equipment by a method in which stoppers are provided to a rotary fork base and nearby fixing frame in a fork-type automobile parking tower, the rotary fork base is exactly stopped, and an elevating fork is raised. CONSTITUTION:Left and right-handed elevating forks 1a and 1b are moved along a vertically movable guide rail 9 by means of a motor Ma, and a rotary fork base 3 is set on a boarding face E1. The base 3 is provided with a stopper 7 and fixing frames 14 and 15 are provided with stoppers 6 and 8. A car mounted on a housing truck 5 is moved from a housing room R to a vertically movable space E, the forks 1a and 1b are raised and crossed with the truck fork, and the car is received and the truck 5 is returned to the room R. The forks 1a and 1b are lowered, the car is delivered by the fork base 3, and the base 3 is turned and stopped exactly by the stoppers 6 and 8. The car is allowed to go out.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a turntable device for a Hawk type multi-level parking tower.

(Prior art) As shown in Fig. 9, in the conventional hawk-type multi-level parking tower turntable, the culm hawks la and lb, which can move up and down in the central space E, load the vehicle to be exited and descend to board the vehicle. At the same time as passing between the hoes 24 of the rotating hawk 3 installed on the surface E1, the car is delivered, stopping at the bit P, the rotating hawk stand 3 rotates 180 degrees, and the left and right elevating hawks la, lb
After making sure to stop at a position where the and Hawk 4 can intersect,
The elevating hawks la and lb slowly rose and stopped at the position where they intersected, completing the entire unloading process.

(Problems to be Solved by the Invention) Regarding the parking lot problem in modern city life, it is necessary to save even a second and shorten the time required for entry and exit in multi-story parking towers. In the unloading process, it is sufficient to increase the rotational speed of the rotary hawk stand 3, but as the speed increases, the inertia force also increases and the stop position by the limit switch is unstable, requiring confirmation and caution when raising the elevating hawks 1a and 1b. This was one of the disadvantageous factors in shortening delivery time.

(Means for solving the problem) In order to ensure that the rotating hawk stand 3 can stop accurately at a designated position without being affected by inertia, a stopper is installed on the fixed frame on the boarding surface to determine the rotation stop position. The main idea is to install it so that it can be rotated left and right.

(Function) A stopper 7 is attached to the rotating hawk stand 3, a stopper 6 is provided to the fixed frame 14 located at the front on the boarding surface, a stopper 8 is also provided to the fixed member 15 located at the rear, and the rotating hawk stand is installed. 3 comes close to the stop position, it is stopped via a roller lever type limit switch, or it comes into contact with a stopper and stops.

At that time, the elevating hawks LA and LB can rise and intersect.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. 1a is a left lifting hawk, lb is a right lifting hawk, 2 is a chain for lifting the left and right lifting hawks, and Ma is a motor that drives this chain to lift it. The left and right elevating forks la and lb always remain horizontal at the same speed and move downwards -E within the elevating space E along the elevating guide rail 9.

3 is a rotating hawk stand installed on the boarding surface E1, and a car mounted on the storage trolley 5 is moved from the storage room R to the elevating space E by the drive of a plurality of rollers 11, and the left and right elevating hawks la
, lb rises, intersects with the storage truck Hawk 10, receives the car, and stops slightly above the storage truck. The storage cart 5 moves to its original position in the storage room R, and the left and right lifting hawks la and lb descend, intersect with the hawk 4 of the rotating hawk stand 3 located on the boarding surface El, and transfer the car to the bit P. An absolute installed on the motor M detects that the rotating fork stand 3 stops on the rail 12 by a plurality of rollers 13 provided on the rail 12.

Figure 2 is a view of the rotary hawk stand 3 rotated 90 degrees, 180 degrees.
° It is stopped by limit switch A (1m not shown) at the rotated position, but to prevent overrun due to inertia difference such as difference in vehicle weight, stoppers 6 and 8 are installed at the stop position, and shock absorbing rubber is attached to the members. , rotating hawk stand 3
Similarly, a stopper 7 is installed at the stopper 7 for accurate stopping.

In addition, in the embodiment (2), as shown in FIG. 4, the car is delivered to the rotary fork stand 3 by an absolute during the car unloading process, and the rotary fork stand 3 starts rotating at 180°I.
It is stopped by a signal from a limit switch at the position where it has turned 51, and the stopper 6.8 is used to prevent overrun of inertial force, and it is stopped in a state where it overlaps the lifting hawks 1a and 1b to form a horizontal plane at the intersection. The rotary hawk stand 3 is located on the boarding surface El, allowing safe passage of people and facilitating the exit of automobiles.

In addition, the rotating hawk stand 3 can rotate clockwise 180" and counterclockwise 180".
It operates in the sequential shipping process.

Furthermore, the stopper can be attached to the rotating fork joint 3, but if it is only possible to attach it to one side of the fixed frame 14 or 15 due to electrical equipment or architectural issues, it is possible to attach the stopper to the rotating fork joint 3. There are a stopper 16 and a stopper 17 as shown in FIG. 6(b), and the stopper 1 as shown in FIG. 6(a).
7 can intersect with stopper 16, but stopper 17
It comes in contact with and acts as a stopper. Moreover, the stopper may have an uneven shape regardless of the shape cut diagonally (see FIG. 7). Therefore, the stopper 16° 17 is attached to the fixed frame 14 shown in FIG. If the stopper 16 is attached to the opposite tip and rotated clockwise, the stopper 17 and the stopper 16 will intersect and come into contact at the stopper 17 and stop. Further, when the rotary hawk base 3 is rotated to the left, the stopper 16 of the rotary hawk stand 3 crosses the stopper 17 attached to the fixed frame 14 and comes into contact with the stopper 6, so overrun can be prevented.

In addition, a fixed frame installed on the front and back of the circumference of the rotary fork stand 3 was installed on the entry surface El, and an entrance and exit was provided on the entry surface El so that the rotary fork stand 3 could be rotated 90@ to enter and exit the warehouse. case(
(path shown), stopper 6°8 or stopper 16.17
The installation can be applied to roads, buildings, etc. so that vehicles can be quickly entered and exited.

(Effect of the invention) As explained above, by providing the stopper on the rotary hawk stand 3, the position where the elevating fork intersects is reliably determined, making it easy to increase the rotational speed of the rotary fork stand, and moving the elevating fork from within the focus. Since the rising speed can also be increased, it is extremely effective in safely and easily shortening the time required for unloading.
