Description

[Detailed Description of the Invention] The present invention relates to an improvement of a three-level parking facility that aims to reduce equipment costs by reducing the required parking space.

Conventionally, for example, as shown in Fig. 1, a three-level parking space is formed in the above-ground part 1a of a building 1, and a two-level parking space is formed in the underground pit part 1b.・Middle/lower three-tier palette 3・
4 and 5 are integrally connected and raised and lowered as appropriate by the lifting device 6, the desired pallet is placed at the entrance 2, and the vehicle W is entered and exited. There is a three-level parking facility that serves as an evacuation space for pallets.

By the way, in the case of mechanical parking equipment that requires a person to enter the parking equipment and get onto the vehicle mounting cage or pallet when entering and exiting the parking lot, the distance between pallets at the entrance and exit (from the top surface of the pallet to the bottom surface of the pallet directly above it) The distance (distance) is stipulated by law to be 1.8 m or more so that a tall person M can enter and exit the desired pallet without bending down. However, based on this regulation, in the aforementioned three-tier parking facility, the spacing between upper, middle, and lower pallets 3, 4, and 5 is fixedly set at 1.8 m.

However, if the target is a regular passenger car, it is known that a pallet spacing of about 1.6 m is sufficient for accommodating the vehicle. Taking this into account, fixing the interval between each pallet to 1.8 m as described above would result in the height of the above-ground part 1a and the depth of the underground pit part 1b becoming larger than necessary, especially in cities with high land prices. In some areas, equipment costs are relatively high, and when installing parking equipment into an existing building, it may not be possible to install it if the height above ground or the depth underground is slightly small.

In view of the above-mentioned circumstances, the present invention suspends the upper pallet by a lifting chain linked to the lifting device, and the upper ends of the middle pallets are respectively engaged near the front and rear sides of both sides of the upper pallet, and are separated slightly from the engagement parts. Guide pulleys are provided at the front and rear sides of both sides of the upper pallet so that their upper surfaces are approximately on the same level as the engaging portions, and at least four pulleys are connected from the engaging point through the guide pulleys and whose lower ends are engaged with the middle pallet. The lower pallet is suspended by the first rope, and the lower pallet is suspended by at least three second ropes whose ends are attached to the middle and lower pallets, respectively, so that in normal hanging conditions, the pallets are at intervals that allow vehicles to enter and exit the warehouse. Then, a fixed pulley was provided protruding from the fixed part of the fourth parking space onto the lifting path of the first rope between the engaging part and the guide pulley so as to be above the first rope, and the intermediate pallet was lowered. At the time of engagement, an appropriate number of stoppers are provided in the underground pit so that the interval between the middle pallet and the upper pallet at the ground floor position when engaged is such that a vehicle can be accommodated. The distance between a certain middle pallet and the lower pallet that has landed on the floor is set to a pit depth that is sufficient to accommodate vehicles, and the vertical spacing of the pallets is changed between loading and unloading and storage to make effective use of the storage space. This is the purpose.

The above is a detailed description based on the embodiments shown in the drawings. For convenience of explanation, the left and right in Figures 2, 4, and 5 are referred to as "front" and "rear," and the left and right in Figure 3 are referred to as "left."
It is called "right".

10 is a building, 11 is an underground pit dug in the ground floor 12 of the building 10, and inside the underground pit 11, first and second parking spaces 13 and 14 are formed from the bottom,
Third, fourth, and fifth tier parking spaces 15, 16, and 17 from the bottom are formed in the above-ground part of the building 10, and an entrance/exit 18 is provided in front of the third tier parking space 15.

Then, the thickness of the vehicle tower pallet, which will be described later, is d, and the minimum pallet spacing required to accommodate the maximum loaded vehicle W (hereinafter referred to as vehicle accommodating spacing)
When is L ₁ and the pallet interval required for the vehicle W to enter and exit the warehouse at the entrance 18 stipulated by law (hereinafter referred to as the possible entry/exit interval) is L ₂ (>L ₁ ),
Ground height H inside the building 10 and underground pit 11
Depth D is H=2L ₁ +L ₂ +2d, D=2L ₁ +
It's set to 3D.

19, 20, and 21 are the upper, middle, and lower pallets for loading the vehicle W, and 22 is the front of the pallets 19 to 21.
At the rear, on the left and right sides, a pair of vertical guide rails with the lower end fixed to the pit floor 11a and the upper end fixed to the ceiling 10a of the building 10 with the recessed part facing the pallet side are used to attach the upper, middle and lower tiers to the recessed part. Palette 1
Guide roller 2 pivoted on the side of 9, 20, 21
3, 24, and 25 are rotatably engaged to guide the pallet when it is raised or lowered.

26 is a chain installed at the upper rear of building 10.
A lifting device consisting of a sprocket mechanism that lifts the ceiling 10
A total of four lifting chains 27, two on the left and one on the right, are led horizontally forward along the ceiling 10a.
The upper pallet 19 is suspended horizontally by being suspended from the front and rear suspension sprockets 28 and engaged with the front, rear, left and right upper surfaces of the upper pallet 19.

29 is the first rope that suspends the middle pallet 20 from the upper pallet 19 by changing the vertical interval;
Four right, front, and rear rods are used, and one end of each is attached to the vicinity of each of the vertical guide rails 22 at the front and rear of the left and right sides of the upper pallet 19, and the rods are connected in the front and rear horizontal directions away from the vertical guide rails 22. extension (hereinafter,
This part is called the horizontal path part 29a), and is hung around a guide pulley 30 that is pivotally supported on the front and rear of the left and right sides of the upper pallet 19, and the other end is connected to the middle pallet 20.
It is attached to the front and rear of the left and right sides.

31 is the middle pallet 20 to the lower pallet 21
Four second ropes, left and right, front and rear, are stretched between the two pallets to horizontally suspend the pallets.

and the first rope 29 and the second rope 31
In this case, the lifting chain 27 is connected to the upper, middle and lower pallets 1.
In the normal state where 9, 20, and 21 are hung,
The lengths of the upper and middle pallets 19 and 20 and the middle and lower pallets 20 and 21 are both set to the above-mentioned loading/unloading interval _L2 .

A fixed pulley 32 is pivotally supported on each vertical guide rail 22 in the fourth-stage parking space 16 via appropriate brackets, and is disposed in the vertical path of the horizontal path section 29a as the upper-stage pallet 19 moves up and down. Therefore, the fixed pulley 32 is moved to the horizontal path portion 29a while the upper pallet 19 is rising.
By engaging with and forming a loop of the first rope 29 in this part, the upper pallet 19 pulls up the middle pallet 20 and lifts the upper and middle pallets 19 and 2.
0 is shortened to the vehicle accommodating interval _L1 .

Reference numeral 33 denotes four engaging pieces protruding from the front and rear ends of the left and right sides of the middle pallet 20, which engage the front and rear parts at the middle depth position of the underground pit 11 during the pallet lowering operation.
Four stoppers 3 protruding from the rear walls 11b and 11c
4 to stop the middle pallet 20 at a predetermined position in the second parking space 14.

The LC is a safety lock device fixed at appropriate locations on the front and rear walls 10b and 10c of the building 10 and the front and rear walls 11b and 11c of the underground pit 11, and locks the front and rear surfaces of each pallet 19 to 21 by extending the rod at appropriate times. It fits loosely into the drilled recess to prevent a pallet from falling due to chain rope breakage.

When in use, when loading and unloading the upper pallet 19, as shown in Fig. 5, the upper, middle and lower pallets 19, 20 and 21 are lowered together, so that the lower pallet 21 first lands on the pit floor 11a and then 2 ropes 31 become slack, and then the middle pallet 20 contacts the snapper 34 via the engagement piece 33 to reduce the distance between it and the lower pallet 21 to the vehicle accommodating distance.
It stops in the state where it is shortened to L ₁ , and then the first rope 2
9 is also loosened, and finally the upper pallet 19 is attached to the ground floor 12.
Stop when they are even. At this time,
The interval between the upper and middle pallets 19 and 20 is also naturally reduced to the vehicle accommodating interval L ₁ due to the dimensional relationship of the depth D of the underground pit 11 = 2L ₁ +3d. This allows loading and unloading to and from the upper pallet 19.

As a result, when loading and unloading the middle pallet 20, as shown in FIG.
Raise 9, 20, and 21 in sequence, and move to middle pallet 2.
0 is flush with the ground floor 12, the interval between the upper and middle pallets 19 and 20 has widened to the original possible loading/unloading distance _L2 , so loading and unloading to the middle pallet 20 is possible. becomes.

Furthermore, as shown in FIG. 2, when loading and unloading the lower pallet 21, the upper, middle, and lower pallets 19, 20, and 21 are raised integrally.
If the lower pallet 21 is stopped when it is flush with the ground floor 12, the middle and lower pallets 20 and 2
Since the interval 1 remains the above-mentioned loading/unloading interval _L2 , loading/unloading to/from the lower pallet 21 is possible. At the final stage of this pallet lifting operation,
The horizontal path portion 29a engages with the fixed pulley 32, and the first rope 29 in this portion is forcibly formed into a loop, and this loop amount reaches a predetermined amount (L ₂ −L ₁ ) when the ascent is stopped. The interval between the upper and middle pallets 19 and 20 is reduced to the above-mentioned vehicle accommodating interval L ₁ , and the interval between the ceiling 10a and the upper pallet 19 is also reduced to the vehicle accommodating interval L ₁ due to the dimensional relationship of ground height H = 2L ₁ + L ₂ + 2d. It is shrinking to

As detailed above, when using the three-level parking system of the present invention, the interval between the desired pallet placed at the entrance/exit and the pallet above it is kept wide enough to allow entry/exit. Although it is possible,
When loading and unloading the lower pallet and upper pallet, the upper and lower pallets evacuate to the parking space above the ground respectively.
The spacing between the middle pallets and the spacing between the upper, middle and lower pallets retracted into the underground pit are determined by the cooperation between the first rope and the fixed pulley and the engagement between the stopper in the underground pit and the middle pallet engaging piece. Because the spacing has been shortened to accommodate vehicles, the ground height inside the building can be lowered and the depth of the underground pit shallower than with conventional equipment, and no special external power is required to shorten the pallet spacing, making it easier to use parking equipment. This makes it possible to significantly reduce the overall equipment cost.
