SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a drive sprocket having equal pitches connected to four corners of a pallet for mounting on a vehicle and rotating at equal speeds. And the chain is wound up or unwound by the driving sprockets, whereby the pallet is raised and lowered between a ground contact position and a parking position above the pallet. Equipment is installed on the slope,
The drive sprockets have different diameters so that the pallet is horizontal at the upper parking position and is inclined at the ground contact position on the inclined ground at the same inclination as the inclined ground.

[0007]

The pallet for mounting the vehicle is moved up and down between the ground contact position on the inclined ground and the parking position thereabove by the action of winding or unwinding each chain by each drive sprocket.

Here, the respective chains have the same pitch with each other, and the respective drive sprockets rotate at the same speed with each other and have the same pitch with each other. Since the driving sprockets rotate at the same speed to each other, the number of rotations per unit time is the same, but if their diameters are different,
The winding and unwinding lengths of the chain in unit time are different.

The diameter of each drive sprocket is:
The pallet suspended by the chain is configured so as to be horizontal at the upper parking position and at the ground contact position on the sloping ground so as to be inclined at the same inclination as the sloping ground.

Therefore, the pallet descends while gradually inclining along the inclination of the sloping ground in the process of descending from the horizontal upper parking position to the ground contact position. On the other hand, the pallet is gradually corrected in the course of ascending from the ground contact position on the ground surface to the upper parking position in the inclined state, and when the pallet finally reaches the upper parking position, the pallet is in the horizontal state. Become.

Therefore, according to the present invention, if there is at least one parking lot site for one vehicle, even if the parking lot site is an inclined surface, a large amount of civil engineering work is required to level the inclined site horizontally. , The vehicle can be parked in the upper parking position and the inclined ground below the upper parking position in two vertical stages.

The device of the present invention includes a pallet lifting mechanism.

Here, the pallet lifting mechanism is shown in FIG.
As shown in the figure, chains 2a, 2b, 2c, 2d at equal pitches connected to the four corners of the vehicle mounting pallet 1.
Are respectively wound around drive sprockets 3a, 3b, 3c, 3d which rotate at the same speed to each other, and the chains 2a to 2d are wound or unwound by the drive sprockets 3a to 3d, respectively. Means that the pallet 1 can be moved up and down between the ground contact position A and the parking position B thereabove.

The device of the present invention can be embodied in any parking device provided with the pallet elevating mechanism, and other detailed configurations are not related to the main part of the present invention, and therefore description thereof is omitted. .

The pallet 1 is made of a rectangular steel plate or the like large enough to mount the vehicle C on the upper surface 1a, and has, at substantially four corners, one end 4 of the chains 2a, 2b, 2c, 2d.
a, 4b, 4c, and 4d are fixed respectively. The pallet 1 is suspended from an elevating reference member 5 such as four post frames or a rectangular frame by the chains 2a to 2d.

The four chains 2a, 2b, 2c, 2
d are mutually equal pitch. Each chain 2
a, 2b, 2c, 2d are extended upward, and the elevating sprockets 6a,
6b, 6c, and 6d.

The lifting sprockets 6a to 6d are
They have the same pitch as each other, and have the same pitch as the four chains 2a to 2d. Each of the elevating sprockets 6a to 6d has a support shaft 7a,
7b, 7c and 7d are attached to the elevation reference member 5 with the pallet 1 facing left and right (in the width direction of the pallet 1).

The chains 2a to 2d are wound around the elevating sprockets 6a to 6d, respectively, and then delivered to the rear of the elevating reference member 5.

A drive shaft 8 extending in parallel with the support shafts 7a to 7d of the elevating sprockets 6a to 6d is attached to the rear portion of the elevating reference member 5 via a bearing (not shown).

A power transmission sprocket 9 is fixed to an appropriate position of the drive shaft 8, and the power transmission sprocket 9 is, for example, a forward / reverse rotatable speed reducer fixed to the elevation reference member 5. It is linked to a driving source such as a motor 10.

The drive sprockets 3a, 3b, 3c and 3d are fixed to both left and right ends of the drive shaft 8, respectively. These drive sprockets 3a to 3d have the same pitch as each other and have the same pitch as the chains 2a to 2d. Each drive sprocket 3a ~
On the 3d, the chains 3a to 3d are wound around from above and the other ends 11a, 11b, 11c and 11d are hung down.

When the motor 10 is operated, the drive shaft 8 is rotated, and the drive sprockets 3a to 3d fixed to the drive shaft 10 are driven to rotate at a constant speed, whereby the chains 2a to 2d are driven. Is unwound or unwound, and the pallet 1 moves up and down.

The pallet 1 is moved up and down between a ground contact position A on the ground surface and a parking position B above the pallet 1 by the pallet elevating mechanism. That is, the vehicle C that descends to the ground surface and travels in a direction that coincides with the longitudinal direction of the pallet 1 is received, and then rises and stops at the upper parking position B. Further, another vehicle C is allowed to run and enter the warehouse.

In the device of the present invention, the pallet lifting mechanism as described above is provided on an inclined ground G having a gentle inclination.

As shown in FIG. 2, for example, as shown in FIG. 2, the pallet 1 is placed on a slope G inclined downward from the left to the right, from the near side of FIG. Is installed vertically, that is, the drive shaft 8 extends from the upper side to the lower side of the slope G.

The pallet 1 is horizontal at the upper parking position B, and the slope G
The driving sprockets 3a to 3d are configured to have different diameters so that the driving sprockets 3a to 3d are inclined at the same level as the inclination of the inclined ground G at the ground contact position A on the ground.

That is, the driving sprockets 3a to 3
d, two drive sprockets 3a, 3 which wind up (or unwind) the two chains 2a, 2b on the inclined upper side.
b, the two drive sprockets 3c, 3 which wind up (or unwind) the two chains 2c, 2d on the inclined lower side.
d is a larger sprocket.

For example, as shown in FIG.
Is arranged, the pallet is compared with two drive sprockets 3a and 3b (two drive sprockets at the left end of the drive shaft 8) that wind up the two front and rear chains 2a and 2b on the left side of the pallet 1. The two drive sprockets 3c and 3d (the two drive sprockets at the right end of the drive shaft 8) that wind up the two front and rear chains 2c and 2d on the right side of 1 are large in diameter.

As described above, each drive sprocket 3a
3d are of equal pitch to each other, the difference in their diameters means that the two chains 2a, 2b
This means that the two sprockets 3c and 3d that wind up the two inclined lower chains 2c and 2d have more teeth than the two sprockets 3a and 3b that wind up.

Now, two chains 2a and 2b on the upper side of the pallet 1 and two chains 2 on the lower side of the pallet 1
The required winding lengths of c and 2d are L (mm) and M, respectively.
(Mm), the pitch of each of the driving sprockets 3a to 3d and the chains 2a to 2d is P (mm), the number of teeth of the small diameter driving sprockets 3a and 3b is X, and the number of teeth of the large diameter driving sprockets 3c and 3d. Is Y.

Then, the small-diameter drive sprocket 3a,
The length of the chains 2a and 2b which are wound up (or unwound) by one rotation of the chain 3b is PX (m
m), the length of the chains 2c, 2d wound up (or unwound) by one rotation of the large diameter drive sprockets 3c, 3d is represented by PY (mm).

Here, each of the small-diameter drive sprockets 3
a, 3b and the large-diameter drive sprockets 3c, 3d are fixed to the same drive shaft 8, so that the pallet 1 is lowered from the upper parking position B to the ground contact position A (or When the pallet 1 is raised from the ground contact position A to the upper parking position B)
The rotation speeds of the small-diameter drive sprockets 3a and 3b and the large-diameter drive sprockets 3c and 3d are the same.

Therefore, L / PX = M / PY.

Therefore, the relationship of X: Y = L: M is established, that is, the small-diameter drive sprocket 3
The ratio of the number of teeth of the large diameter drive sprockets 3c, 3d to the required number of hoisting lengths of the chains 2a, 2b on the upper inclined side and the chains 2c, 2d on the lower inclined side is configured to be equal. do it.

The multi-story parking device for a slope according to the present invention constructed as described above operates as follows.

When the vehicle C is placed on the pallet 1, the motor 10 is operated to lower the pallet 1 to the ground contact position A. When the pallet 1 is at the parking position B above the ground contact position A, the pallet 1 is suspended and supported by the elevating reference member 5 in a horizontal state by the chains 2a to 2d.

The rotation of the drive shaft 8 accompanying the operation of the motor 10 causes the small-diameter drive sprockets 3a, 3
When b and the large-diameter drive sprockets 3c and 3d rotate in the direction of unwinding the chains 2a, 2b, 2c and 2d, the pallet 1 descends.

Here, the small-diameter drive sprocket 3a,
3b and the large-diameter drive sprockets 3c and 3d have the same pitch. Moreover, each sprocket 3a
3d are fixed to the same drive shaft 8 and rotate at the same speed. Therefore, the unwinding lengths of the chains 2a (2b) and 2c (2d) due to one rotation of the small diameter and large diameter sprockets 3a (3b) and 3c (3d) are different. That is, the large-diameter drive sprocket 3
The chains 2c and 2d wound around c and 3d are
It is unwound longer per unit time than the chains 3c, 3d wound around the small diameter drive sprockets 3a, 3b.

For this reason, the pallet 1 descends while gradually inclining along the inclination of the slope G while descending from the horizontal upper parking position B to the ground contact position A in a horizontal state. .

The vehicle C rides on the pallet 1 (shown by a broken line in FIG. 2), which is in contact with the ground, in a direction corresponding to its length. The pallet 1 has a slope G
, The vehicle C enters the pallet 1 from the sloping ground G smoothly without using a board or the like.

As shown in FIG. 2, the pallet 1 on which the vehicle C is mounted is gradually corrected in the course of ascending from the ground contact position A in the inclined state to the upper parking position B. When the vehicle finally reaches the upper parking position B, the vehicle is in a horizontal state.

Further, another vehicle C can be parked on the slope G below the upper parking position B.

In the above description, the longitudinal direction of the pallet 1 is set so that the longitudinal direction of the pallet 1 is the inclination direction of the inclined ground G (the left-right direction in FIG. 2).
Although the case where it is installed so as to be at a right angle has been described,
The present invention can be implemented even when the pallet is installed such that the longitudinal direction of the pallet and the inclination direction of the slope G match.

[0046]

According to the present invention, it is possible to park a large number of vehicles only on the foundation work without performing civil engineering work to level the slope horizontally on the slope ground which has been difficult in the past. Yes, it is cost effective.

Further, the pallet descending to the slope is inclined so as to be along the slope when touching the slope. Therefore, when the vehicle enters the pallet, the sloping member is required to be moved. There is an advantage that it is not necessary to take special measures such as providing.
