Abstract

PROBLEM TO BE SOLVED: To easily adjust an inclination of a raising/lowering pallet by constituting a raising/lowering body of a raising/lowering pallet, a tension bar and a balance chain in a parking garage facility having a cantilever type raising/lowering pallet. SOLUTION: An upper rolling wheel 25 is raised and lowered by a motor driven winch 34 by using a column 21 as a guide. A raising/lowering pallet 27 having a lower rolling wheel 26 and a tension bar 29 having the upper rolling wheel 25 are rotatably connected to each other by a pin 36, and the upper rolling wheel 25 and the lower rolling wheel 26 are connected to each other by a balance chain 30, and a raising/lowering body is constituted. The balance chain 30 is tensioned since the center of gravity of the raising/lowering body exists on the column 21 side more than the pin 36 in a housing condition, and relaxes when the lower rolling wheel 26 comes into contact with a stopper 37 of a column 21 in a floor landing condition. Therefore, in an inclination adjustment of the raising/lowering pallet 27, a required process is only to adjust a length of the balance chain 30 in a housing condition and a height of the stopper 37 in a floor landing condition. An overturning preventive material 30 prevents an excessive inclination of the raising/lowering pallet 27 by restricting a reduction in an interval between the upper rolling wheel 25 and the lower rolling wheel 26.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet tilting device in a parking facility having a cantilever type lifting pallet, in which the tilt of the lifting pallet is changed between a landing state and a storage state. It is.

[0002]

2. Description of the Related Art FIG. 2 shows a conventional pallet inclining device for changing the inclination of a lifting pallet between a landing state and a storage state in a parking facility having a cantilever type lifting pallet. As described above, the column 1 erected on the floor 2 is a guide rail having a front edge 12 and a rear edge 13, and an elevating frame 4 having upper and lower rolling wheels 5 and 6 engaged with the guide rail is provided so as to be able to move up and down. The elevating pallet 7 on which the automobile 8 is placed is fixed to the lower end of the elevating frame 4 at the longitudinal end thereof to form the elevating body 3, and the position of the rolling wheel 6 below the elevating frame 4 when the elevating body 3 is stored. Below, in some cases, the trailing edge 13 is bent back to increase the distance between the leading edge 12 and the trailing edge 13 of the strut 1.

Since the lifting pallet 7 is supported by the lifting frame 4 in a cantilever manner, the rolling wheel 5 above the lifting frame 4 comes into contact with the front edge 12 by a counterclockwise moment in the drawing.
The lower rolling wheel 6 abuts on the trailing edge 13. While the lifting body 3 rises from the landing state to the retracted state, the lower wheel 6 rises along the trailing edge 13 and moves forward, so that the inclination of the lifting pallet 7 is the inclination in the landing state. changes from the corner theta ₂ to the inclination angle theta ₁ in a retracted state.

However, in such a structure of the pallet inclining device, a part of the channel steel or the H-shaped steel used as the support member is cut in order to bend the rear edge 13 at the lower portion of the support 1. In addition, bending and welding work such as welding of reinforcing materials are required, which increases the man-hours and costs, and also tends to cause variations in the accuracy of the finished dimensions. There is a problem that processing is not preferable in terms of strength.

Therefore, as shown in FIG. 3, the column 1 erected on the floor 2 is a guide rail having a front edge 12 and a rear edge 13 and is engaged with the front edge 12 and the rear edge 13 of the column 1 respectively. Frame 4 having upper and lower rolling wheels 5 and 6 is provided so as to be able to move up and down, and the longitudinal rear end of an elevator pallet 7 on which a car 8 is mounted is fixed to the elevator frame 4. In a parking facility in which a tension bar 9 is connected to an intermediate portion of the support member 1 to form the elevating body 3, a front edge 12 and a rear edge 13
The distance between the rolling pallets 5 and 6 is larger than the
A pallet inclining device has been proposed in which the support column 1 is provided with a taper block 17 for displacing the upper wheel 5 backward and a taper block 18 for displacing the lower wheel 6 forward at the storage position. (See Utility Model Registration No. 3013632).

[0006] Since the lifting pallet 7 is cantilevered by the lifting frame 4, the rolling wheel 5 above the lifting frame 4 abuts on the front edge 12 of the column 1, and the lower rolling wheel 6 contacts the rear edge 6. Abut The lifting body 3 is lifted by the chain 15 of the electric winch 14 and the pallet 7
When the vehicle is raised from the landing position, the upper rolling wheel 5
Along, the lower wheel 6 rises along the trailing edge 13, and the upper wheel 5 is displaced rearward by the tapered block 17 until the storage position is reached, and the lower wheel 6 is displaced forward. Runode, lift pallet 7 slope changes from the inclined angle theta ₂ in the landing state to the inclined angle theta ₁ in a retracted state.

In this pallet inclining device, it is not necessary to process the rear edge 13 of the column 1 which is troublesome. However, pillar 1
It is necessary to attach the taper blocks 17 and 18 to the tape.
Further, in order to change the inclination of the elevating pallet 7, it is necessary to change the thickness C of the tapered blocks 17, 18, so that it is inevitable due to the processing accuracy of the elevating pallet 7, the elevating frame 4, and the tension bar 9. It is extremely difficult to adjust the resulting difference in height of the tip of the lifting pallet 7.

[0008]

SUMMARY OF THE INVENTION The present invention solves such a problem in a pallet tilting apparatus,
Provides a pallet tilting device that does not require complicated processing of the trailing edge of the column or mounting of a tapered block on the column, which is inexpensive, and easy to change the inclination of the lifting pallet and adjust the height of the tip. The purpose is to do.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a parking facility provided with a cantilever type lifting pallet, wherein a column standing on the floor is a guide rail having a front edge and a rear edge, and the column is provided at the front edge of the column. An upper rolling wheel support that supports an upper rolling wheel that rolls along, an elevating pallet provided with a lower rolling wheel that rolls along the rear edge of the column at the rear end, an elevating pallet and an upper rolling wheel support, The lifting bar is formed by a tension bar that connects the rear end of the lifting pallet and the upper wheel support to the balance chain, and a stopper is provided at the lower part of the support to stop the lowering wheel from descending. By configuring the pallet tilting device, the tilt of the lifting pallet is changed between the landing state and the storage state.

In the retracted state, the balance chain is tensioned by the load, and the upper roller contacts the front edge of the column and the lower roller contacts the rear edge of the column. Is maintained at an inclination angle determined by the length ratio.

When the lifting frame is lowered, the lifting pallet is lowered while maintaining the same inclination angle as that in the retracted state, and when the lower rolling wheel comes into contact with the stopper of the column, the lower rolling wheel thereafter stops lowering. When the lifting frame is further lowered, the balance chain relaxes and the upper rolling wheel descends along the front edge of the support, so that the lifting pallet rotates downward around the lower rolling wheel and the front end of the lifting pallet touches the ground. By the way, it is in a landing state. The inclination angle of the lifting pallet in the landing state is determined by the height of the stopper.

Therefore, the inclination of the lifting pallet in the stored state can be adjusted by adjusting the length of the balance chain.
Further, the inclination of the lifting pallet in the landing state can be easily changed by adjusting the height of the stopper.

When the vehicle is stored, the vehicle is not in a predetermined position on the elevating pallet and the center of gravity of the total weight of the vehicle and the elevating pallet is located forward of the connection point between the elevating pallet and the tension bar. Regardless, when the lifting frame is raised, the lifting pallet may be excessively inclined downward.

If an overturn prevention member is provided at the rear end of the lifting pallet or at the lifting frame, it is possible to prevent the lifting pallet from being excessively inclined downward.

FIG. 1 is a side view of a pallet tilting device of a parking facility according to an embodiment of the present invention.

The column 21 is fixedly erected on the foundation of the floor 22 with anchor bolts 31. This pillar 2
Reference numeral 1 denotes a guide rail having a front edge 32 and a rear edge 33 made of a channel steel, and is rolled along one end of the suspension chain 35 of the electric winch 34 provided on the column 21 along the front edge 32. The upper wheel support 25 is connected to the upper wheel support 25 so as to be movable up and down.

At the rear end of the lifting pallet 27, there is provided a lower rolling wheel 26 which rolls along the rear edge 33 of the column 21. The diameter of the upper rolling wheel 25 and the lower rolling wheel 26 is
It is smaller than the distance between 2 and the trailing edge 33.

The lifting pallet 27 and the upper wheel support 24 are connected by a tension bar 29, and the rear end of the lifting pallet 27 and the upper wheel support 24 are connected by a balance chain 30. The elevating body 23 is formed. The tension bar 29 is rotatably mounted on the elevating pallet 27 with a pin 36. The length of the balance chain 30 is adjusted, and the angle of intersection between the elevating pallet 27 and the tension bar 29 is changed to store the elevating pallet 27. The inclination in the state can be set arbitrarily.

The inclination of the lifting pallet 27 in the retracted state is set so as to have a forward rising inclination angle θ ₁ when no vehicle is loaded. The lower rolling wheel 2 is provided at the lower part of the column 21.
6 is provided with a stopper 37 for stopping the downward movement. On the floor surface 22, a support base 38 for supporting the front end of the elevating pallet 27 when the elevating pallet 27 is on the floor is provided.

The height of the stopper 37 is the
Inclination is set such that the inclination angle theta ₂ of the front edge in a landing state of. The raising and lowering pallet 27 is lowered forward because it is necessary to provide a water gradient for draining the water on the raising and lowering pallet 27, and in a traversing vertical parking system, the pallet of the adjacent traversing truck is driven by the traversing mechanism. This is because, when the vehicle is inclined in terms of structure, the inclination is made uniform to facilitate the entry of the automobile.

A fall prevention member 39 is provided upright at the rear end of the lifting pallet 27. The overturn prevention member 39 has a length that stops the lowering of the upper rolling wheel 25 by contacting the lower end of the upper rolling wheel support 24 when the lifting frame 24 is lowered and the lifting pallet 27 is in a landing state.

First, the front side of the elevating pallet 27 is raised, the inclination angle is changed, and the balance chain 30 is tensioned, and then the elevating body 23 is raised as a whole and returns to the stored state. At this time,
Since the support 21 and the lifting pallet 27 are bent by the weight of the automobile, the lifting pallet 27 is substantially horizontal.

When the vehicle is retracted, the vehicle is not in a predetermined position on the elevating pallet 27, and the center of gravity of the total weight of the vehicle and the elevating pallet 27 is determined by the pin at the connection point between the elevating pallet 27 and the tension bar 29. In the case where the upper wheel support 24 is raised in spite of being in front of the upper wheel 36, a moment for rotating the lifting pallet 27 counterclockwise about the pin 36 acts on the lifting pallet 27. Since the overturn prevention member 39 has a length in contact with the lower end of the upper wheel support 24, the lifting pallet 27 has an inclination angle θ _2.
It does not incline too far downwards beyond.

The overturn prevention member 39 is provided on the lifting pallet 2
It may be provided on the upper wheel support 24 side instead of the 7 side. Also,
As the overturn preventing means, it is also possible to detect the position of the vehicle and lock the winding of the electric winch 34 when the vehicle has not entered the predetermined position on the lifting pallet 27.

[0028]

As described above, the pallet inclining device of the present invention does not require any troublesome processing of the trailing edge of the column or mounting of the tapered block on the column, and the cost is low.
In addition, it is easy to change the inclination of the lifting pallet and adjust the height of the tip. If an overturn prevention material is provided on the rear end of the lifting pallet or on the lifting frame, an excessive downward inclination of the lifting pallet can be prevented.
