BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet elevating device in a multi-story parking garage, and more particularly, to a pallet elevating device in a multi-story multi-story parking garage in which a plurality of rows of parking spaces are formed in each stage. The present invention relates to a pallet elevating mechanism capable of eliminating the descent of an elevating chain after raising a pallet.

[0002]

2. Description of the Related Art In recent years, multi-story parking lots having a structure in which a plurality of parking spaces are arranged vertically and a plurality of parking spaces are arranged on each side. In such a multi-stage double-row parking lot, for example, in the case of a two-stage type, a lower pallet that can be traversed left and right while a vehicle is placed in a lower parking space is provided. on the other hand,
In the upper parking space, an upper pallet that can be lowered to the lower tier is adopted. In general, an extra space is secured beside the lower parking space, and when a vehicle stored in the upper berth is to be unloaded, the lower pallet of the vehicle parked immediately below the lower pallet is sideways. It can be evacuated to. In such a parking facility, four lifting chains are hung from above the upper parking space, thereby supporting the four corners of the upper pallet. For example, a parking facility having such a structure is disclosed in
No. 753. In this type of equipment, each lifting chain is supported by a sprocket installed on a beam or the like, and the direction is changed by 180 degrees. The rotation of the sprocket raises the lifting chain and raises the pallet, or it can be extended and lowered. Has become. For example, when the lower pallet is raised, the sprocket is rotated forward, and the lifting chain lifted along with it is inverted by the sprocket and hangs down on the side of the upper pallet. In this case, in order to avoid excessive hanging of the hoisting chain, the end of the hoisting chain is fixed to a beam or the like, and the hoisting chain inverted by a sprocket is held in a U-shape so as to hang down. In order to prevent the elevating chain from getting entangled and to make the movement smooth, a weight is attached to the lower end of the hanging elevating chain.

[0003]

As described above, when the elevating chain is hung in a U-shape or the weight is suspended, the upper pallet is raised and the vehicle is stored in the upper parking space. In this case, since the lifting chain and weights that have been inverted by the sprocket and hang down extend to the side of the lower pallet, they become obstructive and significantly degrade the appearance of the parking lot. Not only that, but the lifting chains and weights may touch the clothes and body of customers getting on and off the vehicle in the lower parking space, and may even be shaken and hit the vehicle in the event of an earthquake or typhoon. There's a problem. If the parking facilities are multi-tiered, such as three-tiered or four-tiered, there is more and more opportunity for the above to occur,
Applying such a structure requires various improvements. The present invention has been made in view of the above-described problem, and its purpose is to make the upper pallet lift so that the elevating chain suspending the upper pallet does not sag even after being inverted by the sprocket. It is an object of the present invention to provide a pallet elevating / lowering device in a multi-story parking garage, which does not interfere with getting on and off the lower parking space and does not touch the body or damage the vehicle.

In this example, the left 4L, the support sprocket 10 for stretching the lifting chain 8A extending from hanging position h ₁ of the front of the pallet 2, for stretching the lifting chain 8C which extends from the lifting position h ₃ of the rear side It is arranged outside the support sprocket 12. Also on the right side 4R, the supporting sprocket 11 that stretches the long lifting chain 8B is disposed outside the supporting sprocket 13 that stretches the short lifting chain 8D.

At the intersection of the vertical girder 4a and the horizontal girder 4d at the rear of the left side 4L, a gantry 14a (see FIG. 1) fixed to the upper and inner surfaces of the horizontal girder 4d is provided.
A geared motor 14 having a built-in speed reducer for driving the four lifting chains 8, 8 and having a driving sprocket 20A on the output shaft is attached. The geared motor 1
The bearings 15a, 15b,
15a is installed, and the torque shaft 15 is supported.
On the left side of the torque shaft 15, a large-diameter deceleration sprocket 20B and two elevating chains 8A and 8C located on the left side 4L after being turned horizontally are connected by 180.
Sprockets 16 and 18 for reversing the degree are mounted. Also on the right side 4R, reversing sprockets 17, 19 for reversing the two horizontally diverted lifting chains 8B, 8D by 180 degrees are mounted. on the other hand,
A drive chain 21 (see FIG. 1) is stretched between the drive sprocket 20A of the geared motor 14 and the deceleration sprocket 20B of the torque shaft 15. When the geared motor 14 is driven, the drive chain 21 is interposed through the torque shaft 15. all of reversal sprockets 16 to 19 Te are simultaneously rotated in the same direction, in a state where the hanging position _{h 1, h 2, h 3} , h 4 is kept horizontal, the pallet 2 can be raised or lowered.

When the pallet 2 is raised as described above, as shown in FIG.
The two elevating chains 8A, 8C on the left side 4L, which are turned upside down by 8, are placed in a horizontal state with their tips toward the cross beams 4c, and the elevating chains 8B, 8D on the right side 4R, which are inverted by the inverting sprockets 17,19. Are also extended toward the cross beam 4c. For example, on the left 4L,
In the vicinity of the position where the horizontal girder 4c and the vertical girder 4a intersect, a gantry 22a (see FIG. 1) is fixed inside the vertical girder 4a, and as will be described later, one elevating chain 8A, 8C is connected. A rope reel 22A that winds and unwinds the wire rope 23 is attached. Also on the right 4R,
The gantry 22a is attached to the same position of the stringer 4b,
A rope reel 22B capable of winding one wire rope 23 is provided. These rope reels 22 need to be arranged as far as possible in the front-rear direction from the reversing sprockets 16 to 19 in order to secure a transition distance of the lifting chain 8. Hence,
In the present example, as described above, it is installed at the front of the hanging frame 4. However, in the suspension frame 4 installed in the second-stage parking space 42, the pallet 2 is moved up and down only a short distance.
May be installed at the center of the hanging frame 4 in the front-rear direction. However, in the case of the suspension frame 5 of the parking space 43 at the uppermost stage, it is generally necessary to be installed at the front part. As can be seen from this, the vertical distance of the pallet 2 is restricted by the front and rear lengths of the suspension frames 4 and 5.
Therefore, when providing the fourth stage or the fifth stage in the multi-story parking garage, the front and rear dimensions of the suspension frame need only be increased. In such a case, the pallets themselves may be made longer, and modifications may be made such as placing two front and rear vehicles on one pallet.

As shown in FIGS. 6 and 7, the rope reel 22 has a self-winding type drum 22b having a built-in mainspring spring 24, and a drum 22b mounted on a gantry 22a (see FIG. 1) via a support shaft 22c. Bearing column 22 for mounting

According to the above, the wire rope 23 is always drawn in the direction of arrow F, and even if the gear motor 14 is driven to raise the pallet 2, the reversing sprocket 1
The lifting chain 8 is not loosened between 6 and 19. On the other hand, when the geared motor 14 is driven to rotate forward, the wire rope 23 is easily extended from the rope reel 22 by the lifting chain 8 pulled by the reversing sprockets 16 to 19 against the elastic force of the mainspring spring 24. be able to. 8 and 9 show a state in which the two lifting chains 8, 8 are connected to one wire rope 23. FIG. For the connection, a connecting member 25 in which a part of a rectangle is cut off is used. This has one hole at the center of the front end and one hole at each of the left and right ends. The connection member 26 is integrated with the tip of the wire rope 23 and the connection member attached to the end of the lifting chain 8. 2
7 can be fixed using bolts and nuts. With such a connection, the left 4L
Can be simultaneously shifted by the same length. In addition, the wire rope 23, which is extremely easy to wind up and unwind from the rope reel 22, can prevent winding of the elevating chain 8 which is easily entangled.

On the other hand, in FIG. 1, since the suspension frame 4 is movable in the horizontal direction along the left and right beams 56, 56,
A geared motor 28 and a drive wheel 29A rotated by the geared motor 28 are provided at the left rear of the lower surface.
Then, the other three places also have traversing wheels 29B, 29C, 29
D is attached so as to be driven and rotatable. In addition, the traversing wheels 29C and 29D located at the front are formed in a disk shape and run on a flat rail 31B. However, the driving wheels 29A and the traversing wheels 29B located at the rear have V-shaped grooves. Angle steel rails 31 having a triangular shape
A is considered so as to run on A and prevent meandering of the suspension frame 4. Incidentally, a swing preventing member 32 for preventing the pallet 2 from swinging with respect to the hanging frame 4 when the hanging frame 4 traverses with the pallet 2 raised is provided. This is a guide cylinder 32a mounted near the supporting sprockets 10, 13 and having a lower end opened like a bosh.
And a guide rod 32b which is fixed on the pallet 2 immediately below and which is narrowed and rounded at the tip. By doing so, the guide rod 32b is easily guided by the guide cylinder 32a when the pallet 2 moves up, and when the pallet 2 rises to a predetermined height, the guide rod 32b moves.
Are fitted into the guide cylinder 32a, the suspension frame 4 and the pallet 2 are integrated, and unnecessary swinging of the pallet 2 is prevented. The pallet 3 installed in the uppermost parking space 43 has the same structure as the pallet 2 in the second parking space 42, but since the pallet 3 does not need to be traversed, the left and right beams 54, 54 are provided. Frame 5 mounted on
Does not have wheels for traversing and its driving device, as shown in FIGS. Therefore, if the upper frame 57 itself has the function of the hanging frame 5, it is not necessary to place the hanging frame 5 on purpose.

The pallet 1 which can be traversed and installed in the lowermost parking space 41 is shown in FIG.
, Are arranged in pits 41B formed on the floor surface 41A. These are the pallets 2 and 3
Although the plate members 2m and 2n are adhered similarly to the above, the lifting chain is not attached because there is no need to raise and lower. However, since it is necessary to traverse the pallet 1 itself, a traversing means 33 described later is provided. A flat rail 34B is laid at the front of the bottom surface of the pit 41B, and two triangular rails 34A, 34A formed of angle iron are laid at the rear. It is installed to be at the same level as the bottom. Therefore, the upper pallets 2, 3
Descends and enters the pit 41B, the plate materials 2m,
The upper surface of 2n is almost the same height as the floor surface 41A,
Care has been taken to ensure that there is no problem in entering and leaving the vehicle. The traversing means 33 of the pallet 1 includes a geared motor 35 mounted on the back and a V-motor mounted on the drive shaft 35a.
And two drive wheels 36A, 36A having a U-shaped groove. The right rear wheel, which is not shown in the drawing, has the same shape so that the pallet 1 does not meander.

The pallet elevating and lowering device in the multi-story parking garage thus constructed is used to move the vehicles 64 to 70
When the pallets 2 and 3 are moved up and down for loading and unloading one by one, the elevating chain 8 does not hang down from the suspension frame members 4 and 5, the appearance is good and they do not touch the customer or the vehicle. It is possible to smoothly move up and down as shown in FIG. The case where the vehicle 64 is parked on the pallet 2A in the second-stage parking space 42 shown in FIG. 4 will be described. First, irrespective of the presence or absence of the vehicle 61 on the pallet 1A, the pallet 1A is traversed from the position shown in the drawing to the space 41a, and a new lifting space is secured immediately below the pallet 2A. Then, the geared motor 35 (see FIG. 10) is driven to
The pallet 1A is moved along A, 34B. When a limit switch (not shown) operates, the geared motor 35 is activated.
Is stopped, and the pallet 1A stops.

In this state, the geared motor 14 provided on the suspension frame 4 is rotated in the reverse direction, and the torque shaft 15 is rotated in the reverse direction via the drive sprocket 20A, the drive chain 21, and the speed reduction sprocket 20B. The left and right reversing sprockets 10 to 13 are also reversed, and the elevating chains 8A, 8C and 8B, 8D move backward with the wire rope 23 against the winding force of the spring 24 of the rope reel 22, and support the reversing sprockets 16 to 19. Sprockets 10-13
It is lowered through. Each of the lifting chains 8A to 8D is extended by the same length, and four suspension positions h ₁ ,
h _2, h _3, pallets 2A, supported by h ₄ is lowered while maintaining a horizontal attitude. Palette 2A is pit 41
B, the rotation of the geared motor 14 is stopped by an operation of a limit switch (not shown) and the like.
The upper surface of pallet 2A is at the same level as floor surface 41A. In this state, the pallet 2A is
The vehicle 64 is made to enter until the vehicle hits the tire stoppers 6, 6, and the handbrake is applied. Therefore, when the geared motor 14 is rotated forward, the torque shaft 15
Rotates to rotate the left and right reversing sprockets 16 to 19 forward. The lifting chains 8A, 8C and 8B, 8D are raised by the same amount via the supporting sprockets 10-13. Elevating chain 8A inverted by reversing sprockets 16 to 19,
8C, 8B, and 8D move forward by the winding force of the spring 24 of the rope reel 22 via the wire rope 23. The rope reel 22 merely winds up the wire rope 23, and is easily entangled with the elevating chains 8A, 8A.
C, 8B, and 8D are in a stored state along the upper and lower surfaces of the hanging frame 4, and do not become loose.

When the pallet 2A rises to a certain position,
The guide rod 32b attached to the pallet 2A is
The guide tube 32a is fixed to the guide tube 32a, and the subsequent ascent is stabilized. When the pallet 2A rises to a predetermined position, the drive of the geared motor 14 is stopped by an operation of a limit switch or the like. In this manner, the vehicle 64 is smoothly parked in the second-stage parking space 42. Even if a strong wind is received during parking, the swing prevention member 32 and the suspension frame 4 are integrated, and the pallet 2A can be prevented from swinging. Note that when the vehicle 64 is lowered in the state as shown in FIG. 4, the pallet 2A may be traversed into the space 42a before descending without lowering the lowermost pallet 1A. Not even. When the pallet 2A is traversed, the geared motor 28 is driven, and the driving wheels 29A and the driven wheels 29B to 29D are used to drive the rails 31A and 31B.
(See FIG. 2). Incidentally, any pallets 2 and 3 other than the top row only traverse one pallet, and there is no need for complicated control for the movement.

[0017]

According to the present invention, the lifting chain suspending the pallet is stretched on a supporting sprocket for turning in the same horizontal direction above each hanging position, and the same chain is turned. Each of the two lifting chains located on the side
A reversing sprocket for reversing 0 degrees is rotated equally to the left and right via the torque shaft, and the tip of the two elevating chains on each reversed side is connected to one wire rope and wound up. Since the payout rope reel is installed on the hanging body remote from the reversing sprocket, the lifting chain does not drop down to the side of the pallet even when the pallet is raised. Then, only the wire rope for stably maintaining the storage state of the lifting chain is wound around the rope reel, thereby preventing the occurrence of excessive winding and entanglement that occurs when winding the lifting chain. . The lifted chain is invisible and has a good appearance, and the parking lot can be upgraded. In addition, swaying of the hoisting chain, which would occur if they were hanging down, would not damage the customer or the vehicle.
