DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground multi-story parking device.

[0002]

2. Description of the Related Art A conventional underground multi-story parking device is disclosed in
As disclosed in Japanese Patent No. 11089, a ground pallet is provided so as to be able to traverse on a middle frame serving as a traversing rail,
A lifting chain is connected to both ends of the back of the basement pallet, and a balance chain is wrapped around the left and right ends of the back of the basement pallet. One end of the balance chain is connected to the rear support, and the other end is the middle stage of the loading / unloading side. The underground pallet is connected to a connection fitting protruding from the frame, and is moved up and down while horizontally holding the underground pallet by the balance chain.

[0003]

By the way, in the above structure, a downward pulling force acts on the connecting fitting due to the load of the pallet. However, since the connecting fitting is fixed to the outer side surface of the middle frame, this connecting fitting is fixed. A tensile force is applied to a fixing member such as a bolt, and there is a risk that the pallet may be tilted or dropped due to deformation or breakage of the fixing member when used for a long time.

[0004] Further, since the connecting bracket and the fixing member project a large amount toward the parking space side, notches are provided at both ends of the lower pallet, and when the lower pallet is raised, the front portion of the lower pallet is connected to the connecting bracket and the fixing member. It is necessary to avoid interference. Therefore, there is a disadvantage that the number of manufacturing steps is increased and the work is complicated. Accordingly, the present invention provides an underground type in which the fixing member for fixing the connecting fitting is prevented from being deformed and the like, and the projecting amount of the connecting fitting toward the parking space is reduced so that the lower pallet can be raised and lowered without interfering with the connecting fitting. An object of the present invention is to provide a balance chain mounting structure in a multi-story parking device.

SUMMARY OF THE INVENTION The present invention relates to a parking garage having a ground pallet which can be traversed on a frame and a basement pallet which can be raised and lowered horizontally by a lifting chain and a balance chain. An underground parking space provided, wherein the frame is provided with a connection fitting capable of connecting a balance chain to the frame.In the underground multi-story parking device, the connection fitting has a base plate and a connection portion formed in a T shape, The base plate is fixed to the inner surface of the frame, and the connecting portion is connected to an end of the balance chain by protruding from the opening of the frame toward the parking space.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a three-level underground multi-story parking device. The parking device 1 includes an upper parking space 2 and a middle parking space 3 which is a ground parking space.
And a lower parking space 4 which is an underground parking space. The parking device 1 is formed in a lattice shape with a front support 5, a rear support 6, an upper frame 7, a middle frame 8, and an auxiliary frame 9.

An upper pallet 10 is provided on the upper frame 7.
Are suspended by a lifting chain 11 connected to both front and rear ends thereof so as to be able to move up and down. The elevating chain 11 has one end connected to the rear support 6 and the other end driven by a motor 12 fixed to the upper frame 7.
And is connected to the upper pallet 10 by being wrapped around an auxiliary sprocket 14 provided on the upper frame 7 and the motor 1
By rotating the main sprocket 13 at 2, the upper pallet 10 can be moved up and down from the upper parking space 2 to the middle parking space 3.

The middle pallet 1 is placed on the middle frame 8.
5 is provided so as to be able to traverse via a roller 17 driven by a motor 16, and the middle pallet 15 is one pallet smaller to secure a space for ascending and descending the upper pallet 10 and a lower pallet 18 to be described later. I have a number.
Below the middle pallet 15, a lower pallet 18 is connected at both ends at the rear end thereof, and a lifting chain 19, and from the rear support 6 to the front support 5 through both lower ends of the lower pallet 18.
Balance chain 20 wrapped around the middle frame 8
It is suspended so as to be able to ascend and descend while keeping it horizontal.

The elevating chain 19 has one end connected to a weight 22 which moves up and down along a guide 21 provided behind the rear column 6, and the other end driven by a motor 23 fixed to the auxiliary frame 9. It is wound around a sprocket 24 and connected to the rear of the lower pallet 18. The balance chain 20 is connected to an auxiliary sprocket 25 provided at one end below the rear support column 6 and at the other end on the front and rear portions of the lower surface of the lower pallet 18 at the other end thereof. Connected at 26.

The connecting fitting 26 is formed in a T-shape by a base plate 27 and a connecting portion 28 protruding from the base plate 27, as shown in FIGS. The end of the balance chain 20 is connected to an opening 30 formed in the vertical surface 29 of the middle frame 8 by penetrating from the inside of the vertical surface 29 to the outside, that is, to the parking space side. The base plate 27 is fixed to the four corners with mounting bolts 31 and mounting nuts 32, which are fixing members, with the connecting portion 28 penetrating the opening portion 30 and abutting against the inner surface of the vertical surface 29. Reference numeral 33 denotes a support member fixed to the front support 5 and having an L-shaped cross section. The end of the middle frame 8 is placed on the upper surface of the support member 33 to support the lower surface of the middle frame 8. Reference numeral 34 denotes a fixing bolt. The fixing bolt 34 is inserted into a cylindrical member 35 fixed to the end of the middle frame 8, and a fixing nut 37 is screwed on a back surface of a plate 36 fixed to the front support 5. Thus, the middle frame 8 placed on the support member 33 is fixed to the front support 5.

When the lower pallet 18 is raised to the middle parking space 3 by this, the space is secured by traversing the middle pallet 15 above the lower pallet 18, and then the main sprocket 24 is rotated by the motor 23. Thus, the lower pallet 18 is raised and lowered from the lower parking space 4 to the middle parking space 3 while being horizontally held by the balance chain 20.

At this time, a downward tensile force acts on the connection fitting 26 due to the load of the lower pallet 18, but the entire base plate 27 of the connection fitting is attached to the vertical surface 2 of the middle frame 8.
9, the downward pulling force acting on the mounting bolt 31 can be reduced, and the connection fitting 26 can be securely fixed to the middle frame 8. Further, the base plate 27 of the connection fitting 26 is fixed in the dead space inside the middle frame 8, so that the connection
The amount of protrusion of the mounting bolt 31 toward the parking space is reduced, and the lower pallet 18 can be moved up and down without interfering with the connecting portion 28 and the bolt.

In this embodiment, a three-stage underground multi-story parking device has been described. However, the same applies to a two-stage or more underground multi-story parking device that forms a ground parking space and an underground parking space. It has a function and effect. Further, in this embodiment, the balance chain is wrapped around the lower surface of the pallet in the front-rear direction.

[0014]

As described above, according to the present invention, the connecting portion of the connecting fitting is penetrated from the opening of the frame so as to protrude toward the parking space, and the base plate of the connecting fitting is fixed to the inner surface of the frame by the fixing member. Thus, the entire base plate can be received on the inner surface of the frame by the tensile force acting on the connection fitting, and the connection fitting can be securely fixed to the frame. In addition, since the base plate is mounted using the dead space inside the frame, the amount of protrusion of the connection fittings and fixing members to the parking space side can be reduced, and the underground pallet interferes with the connection fittings and fixing members. It can be raised and lowered without any problem.
