Description

[Detailed description of the invention] (Industrial application field) This invention consists of an endless chain stretched between upper and lower sprockets arranged vertically at an appropriate distance, and a large number of vehicles mounted on this endless chain suspended from the upper and lower sprockets. Parking devices that allow parking cages to circulate vertically are arranged in multiple rows, and an entrance is provided above the ground in front of the frontmost parking row, and a communication entrance through which vehicles can enter and exit is formed at the bottom of the bulkhead of the adjacent parking row. This invention relates to a multi-parallel vertical circulation parking facility.

(Prior Art) The following two systems are generally known for the above-mentioned parking equipment. One of them is called the "empty cage passing method", in which when entering or exiting a parking device other than the first row, all parking devices leading to that parking device stop the empty cage at the lowest entry position. Then, the vehicle passes through the empty cage and gets into the target cage, or exits from the target cage through the entrance.

The other method is called the ``cage cutout passage method,'' and as disclosed in Publication of Utility Model Publication No. 46-26054, the parking device in the last row is equipped with all the cages that can be installed. Other parking devices are formed with a cage cutout that can remove one cage, and when entering or exiting a parking device other than the front row, all parking devices leading to that parking device have a cage cutout. The vehicle is stopped at the lowest entry position, and the vehicle passes through the cage cutout to enter the target cage or exit from the target cage to the entrance.

(Problem to be solved by the invention) In the case of the above-mentioned "empty cage passing method," the vehicle must pass between the inverted U-shaped cage frames, which are limited to the minimum necessary width, so it is especially difficult to drive in reverse. Requires fairly advanced driving skills. In addition, in order to enable entry and exit from the parking device in the last row, at least one cage must always be left empty in the other parking devices, which can be said to substantially reduce parking efficiency. .

On the other hand, in the above-mentioned "cage cutout passage method", since there is one less cage, it is obvious that the parking efficiency is lowered.

Furthermore, in either system, an empty cage or a cage missing portion must be placed at the bottom of the front parking device each time the parking device is entered or exited from the rear parking device. When the removal section is located at the top, the waiting time for entering and exiting the warehouse becomes significantly longer.

(Means for solving the problem) In the multi-parallel vertical circulation type parking facility of the present invention, each parking device is arranged so that the lowest cage is successively lowered in a step-like manner, and the floor surface is also located at the entry area except for the parking device in the last row. The steps are formed in a step-wise manner so as to become lower, and except for the last row, the step bed is provided with a deck that can swing up and down with the lower step side as a pivot point,
The deck rises and connects to the elevated side floor when the parking devices other than the last row are stopped with the lowest cage at a position shifted laterally from directly below the center of rotation (i.e., the center of the lower sprocket), and connects to the lowermost floor. The present invention is characterized in that a vehicle can pass through a space formed between the cage and the cage located at the upper side of the cage.

(Function) When entering or exiting a parking device other than the front row, the desired cage of the destination parking device is stopped in line with the path of the vehicle, and the front row parking device moves the lowest cage from directly below the center of the lower sprocket opposite to the path. By shifting the position laterally and raising the deck as necessary to connect the high and low floors, the vehicle passes through the deck and the high and low floors to enter the desired cage or exit from the entrance. Exit. Therefore, all parking devices can be equipped with the entire number of cages that can be installed, and the parking devices on the front row side of the target parking device only need to move the cage group about half a pitch to form a space for vehicles to pass. There is no risk of unnecessary extension of loading/unloading time.

Embodiments Hereinafter, the embodiments will be described in detail based on the embodiments shown in the drawings. For convenience of explanation, left and right in Figures 1 and 2 are referred to as "left" and "left".
``Right'', and the right and left in FIG. 3 are referred to as ``front'' and ``rear''.

In Figures 1 to 3, 1a and 1b are the front column and the rear column, and in this example, the rear column is located slightly to the right from the front column, and the partition wall 1 of both columns 1a and 1b is
In the above-ground part of the front tower 1a, there is a communication port _1c1 which is large enough for vehicles W to pass through, and is located on the right side of the front tower _1a . The entrance/exit _1a11 is open over the entire width in the direction.
The entrance/exit 1a ₁₁ and the communication opening 1c ₁ can be closed by left and right entrance doors 2a, 2b and a partition door 3 which are vertically movably incorporated into the front wall 1a ₁ and the partition 1c, respectively. Further, vertical circulation type front and rear row parking devices 4a and 4b are built into the front and rear towers 1a and 1b.

Each of the parking devices 4a and 4b is a rear parking device 4b.
Sprockets 5a ₁ , 5a ₂ , 5 are arranged in a stepped manner with the sides getting lower, and one pair each for the upper and lower sprockets.
A pair of front and back endless chains 6a, 6 wrapped between b ₁ , 5b ₂
A total number of vehicle tower cages 7a and 7b that can be hung at equal intervals are suspended from the vehicle tower b.

8 is the ground floor at entrance 1a ₁₁ , 9 is the front tower 1
A pit for inserting the chassis 7a ₁ of the cage 7a in a, and the pit floor 9a of the pit 9 extends slightly into the rear tower 1b beyond the communication opening 1c ₁ to connect the rear parking device 4b.
It also serves as a boarding floor. Reference numeral 10 designates a pit for inserting the chassis _7b1 of the cage 7b, which is dug in the pit floor 9a in the rear tower 1b.

The front row parking device 4a is configured to stop when the center position _M1 of the cage 7a reaches a position appropriately shifted to the left from the rotation center P of the lower sprocket _5a2 , as shown in FIGS. At this stop position, the entry surface of the chassis _7a1 is flush with the ground floor 8, and the cage 7a faces the left entrance door 2a. By shifting the predetermined stopping position of the lowest cage 7a to the side, the cage 7a on the upper right side is slightly lowered, and the chassis 7a of the cage 7a is lowered slightly.
Although the distance between a ₁ and the ground floor 8 is also slightly reduced, the distance between the cage 7a in the middle of the rotation of the lower sprocket 5a ₂ and the cage 7a directly above it is originally wider than the distance at the vertical portion, so the maximum distance is reduced. A space S formed below the cage 7a (indicated by the shaded needle lines in FIGS. 1 and 2) located on the side of the lower cage 7a and at the upper side of the lowest cage 7a is a space for vehicles W and people to pass through. It will be large enough.

Further, the rear row parking device 4b determines a stopping position such that the center of the lowest cage 7b substantially coincides with the center of the space S in the left-right direction, and the chassis 7 of the cage 7b located at this stopping position.
_b1 The dimensions of each part are set so that the entry surface is exactly flush with the pit floor 9a.

Reference numeral 11 denotes a movable deck device installed at the front of the right side of the pit 9, in which a rectangular wave-shaped deck 11a large enough to allow the vehicle W to pass through has a shallow rectangular hole 9a ₁ whose rear end is formed in the pit floor 9a. Two actuating cylinders 11b are installed in the recesses _9a2 , which are pivotally mounted to the rear part so as to be swingable up and down, and the lower part of the cylindrical body is supported swingably in the recesses _9a2 dug to the left and right of the center of the rectangular hole 9a1. The ends of the upwardly extending rods _11b1 of the cylinder 11b are pivotally connected to the left and right center portions of the lower surface of the deck 11a.

Therefore, the deck 11a normally fits in the rectangular hole _9a1 in a horizontal state due to the shortening of the rod _11b1 of the operating cylinder 11b, and does not interfere with the circulation movement of the group of cages 7a. And the lowest cage 7a
When the deck 1 stops at the predetermined stop position, the deck 1
The rod 11a is swung upward by the extension of the rod _11b1 of the operating cylinder 11b, so that the front edge of the deck 11a approaches the ground floor 8 flush with it, forming a slope from the ground floor 8 to the pit floor 9a. .

Reference numeral 12 denotes a control device installed outside the entrance 1a ₁₁ , which has an operation panel 12a equipped with a cage call button, an entry status display lamp, a group of manual switches, an automatic/manual changeover switch, an emergency stop button, etc., and controls the entire parking facility. It is a comprehensive control system.

Next, the effect will be explained.

In the initial state of the parking equipment, the deck 11a is lowered and horizontally inserted into the rectangular hole 9a ₁ , and the left and right entrance doors 2a, 2b and bulkhead door 3 are lowered to close the entrance 1a ₁₁ and the communication opening 1c ₁ , respectively. are doing.

First, when entering and leaving the front row parking device 4a,
The group of cages 7a moves in a circular manner by the cage call operation on the operation panel 12a, and the desired cage 7a reaches the predetermined lowermost stop position and stops. The chassis _7a1 of the desired cage 7a is now flush with the ground floor 8 and faces the left entrance door 2a. Next, the left entrance door 2a rises and the left half of the entrance 1a ₁₁ opens.
The vehicle W enters the cage 7a (enters the garage) through the left half opening of the entrance 1a ₁₁ , or the vehicle W exits the cage 7a to the outside of the entrance 1a ₁₁ (exit).

When entering or exiting the rear parking device 4b, the desired cage 7b is placed at the lowermost predetermined stop position by the same operation as described above. The chassis _7b1 of the desired cage 7b is now flush with the pit floor 9a. Furthermore, the movable deck device 11 is connected to the rod 1 of the operating cylinder 11b.
The deck 11a is tilted upward by the _1b1 extension operation, and the front edge of the deck 11a approaches the ground floor 8 flush with it to form a ramp. Next, right entrance door 2b
The bulkhead door 3 rises to open the right half of the entrance/exit 1a ₁₁ and the communication port 1c ₁ , respectively.

Therefore, when warehousing, the vehicle W passes through the space S through the right half opening of the entrance 1a ₁₁ down the ramp of the deck 11a, passes over the pit floor 9a, and then passes through the communication opening 1c ₁ to the rear tower 1b. Go inside and get into the desired cage 7b. In the case of leaving the garage, it is the opposite of entering the warehouse, and the vehicle W passes from the cage 7b to the communication port 1c ₁ , passes through the pit floor 9a, ascends the deck 11a, and enters the entrance 1.
a ₁₁ Exit outside through the right half opening. When these loading/unloading operations are completed, the right entrance warehouse 2b and bulkhead door 3 are closed, and the rod 11b ₁ of the operating cylinder 11b is closed.
Due to the shortening, the deck 11a swings downward and returns to its initial state.

In addition to the embodiments described above, the present invention can also be modified as described below.

() In the above embodiment, the vehicle W enters and exits the front and _{rear parking devices 4a and 4b using the left half and right half of the entrance 1a 11 ,} respectively. Can be implemented. That is, as shown in FIG. 4, the entrance 100a ₁₁ is only on the right half, and the cage 107a of the front row parking device 104a normally stops at a position directly above the movable deck device 111 (double-dashed line in FIG. 4). Carry in and out of the warehouse at this position. Then, only when entering or leaving the rear parking device 104b, the cages 107a are retracted to a position slightly shifted to the left side (solid line in FIG. 4) to form a space above the movable deck device 111 that allows the vehicle W to pass. do. According to the law, an entrance/exit for vehicle W cannot be established within 5 meters from the intersection corner Q, but this example, in which the entrance/exit is pushed to one side, is particularly useful when installing parking facilities at such an intersection corner. It is valid.

() In the first embodiment described above, an example was shown in which the front tower and the rear tower were shifted to the left and right, but it is of course possible to implement the invention even in a case where the center coincides with the vehicle entry direction as shown in FIG.

() As shown in Figure 5, the parking device 2 in the last row
04, the lowermost cage 207 may be stopped directly below the center of rotation _M10 , which is a common usage pattern. Of course, in this case, the turning center M ₁₀ is aligned with the central axis M ₁₁ of the path of the vehicle W.

() If you want to have a little more room in the height direction of the space S, move the ground floor 8 located on the right half of the entrance 1a ₁₁ to the sloped floor 108a slightly downward to the rear, as shown by the two-dot chain line in Figure 3. Just form it.

(Effect of the invention) As explained above, when using the parking equipment of the invention, a movable deck is provided on the pit floor for inserting the lowest cage of each parking equipment except the last row, and the height difference between the stepped floors due to the rise of the deck is provided. At least for each parking device other than the last row, the stop position of the bottom cage is set at an appropriate distance laterally from the center of rotation, either at all times or only when the rear parking device enters and exits. A space is provided below the cage, which is located at the upper side of the lowest cage on the side, to allow vehicles to pass through, making it possible for vehicles to pass inside the cage or creating a cage cutout, unlike in the past. This system has great effects, such as being able to maximize the use of all the cages that can be installed, and functioning as a parallel parking facility without reducing parking efficiency or prolonging the waiting time for entry and exit. It is.
