Abstract

PURPOSE:To miniaturize a sky parking lot device by horizontally placing a hanging shaft between endless chains, and hanging an on-vehicle cage from the hanging shaft, and mounting a chain roller and a roller bearing to the respective portions of the chains, and supporting the roller and the roller bearing using first and second support rails respectively during the horizontal shift of a vehicle. CONSTITUTION:A first combined frame and a second combined frame 14b are provided in a parallel, vertically-spaced relation to each other and a chain wheel 15 is mounted to each of the four corner portions of the inside of each combined frame. A chain roller 16b whose diameter is larger than that of the chain block 16a of an endless chain 16 is interposed in each connecting portion between the chain blocks 16a of the endless chain 16 and also a mounting shaft having a roller bearing 16c fitted therein is projected inward from the center of each block 16a. The endless chain 16 is hanged around the chain wheel 15 and also the roller 16b and the bearing 16c are supported by first and second support rails 24, 25, respectively. A hanging shaft 17 is installed between the respective opposite mounting shafts 16d of two sets of endless chains 16 and an on-vehicle cage 19 is hanged from the hanging shaft 17.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a multi-level car parking system in which chains and wheels are manufactured and assembled in a smaller size by distributing the weight burden.

<Prior art> As shown in Figure 7, in a conventional multi-level parking lot, a chain is hung between two upper and lower chain foils, and the chain is placed between the tips of cantilevered arms extending from the chains. It has been constructed in the same way as a car cage suspended from a hanging shaft.

<Problems to be Solved by the Invention> However, in such multi-story parking garages, the upper and lower chain wheels and chains must be extremely large, and therefore there is a problem that they cannot be manufactured and assembled by small or medium-sized manufacturing equipment. Ta.

<Means for Solving the Problems> The present invention provides a structure in which a first frame and a second frame, which are formed by installing two cross beams between two supports to form a square frame, are placed parallel to each other at a distance. A chain wheel is attached to the inside of the four corners of the square frames of the first and second frames, and a chain roller is interposed between the chain piece and the chain piece on the chain wheel. Two sets of endless chains with mounting shafts fitted with roller hair rings protruding inward from the middle spaced apart are mounted so as to rotate in synchrony, and a plurality of hanging shafts are installed between each of the mounting shafts. A car cage is suspended from each hanging ring, and the chain roller and part of the roller bearing are supported in contact with a support rail installed horizontally between the chain wheels. , the weight burden is square frame and 4
The present invention attempts to solve the above-mentioned problems by miniaturizing the foil and chain by dispersing them into individual foils and associated support members.

Function> The present invention allows a car to be taken in and out of a car cage that is in contact with the ground,
It is lifted off the ground using a chain that rotates along a rectangular frame for multi-level parking. When the suspension shaft of the car cage is running horizontally, the chain rollers and roller bearings located at both ends of the suspension ring are supported by support rails provided at corresponding positions, reducing the weight burden of the endless chain and preventing sagging. Furthermore, during horizontal movement, the hanging arms of the car cage are supported at three points to prevent the car cage from swinging laterally.

<Example> Examples will be described below based on the drawings.

1 to 5 show a first embodiment, in which two pillars 1
The upper cross beam 12a and the upper cross beam 12b are placed between 1a and llb to form a vertically long rectangular frame 13.The first frame 14a and the second frame 14b are installed relative to each other vertically at parallel intervals, and each square frame is A chain coil 15 is attached to the four inner corners of the frame 13, and an endless chain 16, 16 is hung around it. The two sets of endless chains 16 each have a chain roller 16b having a larger diameter than the chain piece 16a interposed at each joint between the chain pieces 16a, and a chain roller 16b having a diameter larger than that of the chain piece 16a is interposed between the chain pieces 16a. A mounting shaft 16d fitted with a roller bearing 16c is arranged to protrude. The hanging shaft 17 is connected between the opposing mounting shafts 16d of the endless chain 16 of 2a by the bolt 5.
A total of five car cages 19 are suspended from each hanging shaft 17. 19a is car cage 1
Two pairs of chevron-shaped hanging arms extending upward from both sides of the frame 9 are used to surround the horizontal part of the frame 19b, and a clamping plate 19c is vertically disposed between the two sides of the frame 19b, and is mounted on the hanging shaft 17. Further, rollers 28a and 28b are provided on one side of the surrounding plate 19b.
is installed so that it rotates.

20 is a motor for synchronously rotating the endless chains 16 and 16, and the motor 20 is connected to the second frame 14 as shown in FIG.
The chain at the lower part of each side is installed on the middle of the upper cross beam 12b of b, and is connected to the lower chain on each side via a transmission shaft 22 which is installed between the lower cross beams 12b of the first frame 14a and the second frame 14b via a reduction mechanism 21. A chain 23 is wrapped around the foil 15 so that it rotates synchronously. Therefore, as shown in FIG. 1, four vehicle cages 19 are suspended in the air along the square frame 13, and one is positioned below the square frame 13 and close to the ground surface so that the car A can enter and exit. The motor 20 is started and the endless chain 16. When J6 is rotated, the vehicle cages 19 are moved in the positional relationship shown in FIG. 1, and the automobile A accommodated in each vehicle cage is multi-level parked.

Therefore, when the vehicle cage 19 moves laterally along the upper cross beam 12a of the square frame I3, its weight is transferred to the two sets of endless chains 1.
However, in the present invention, the roller bearing 16c fitted between the chain roller 16b provided at each connection part of the chain piece 16aU and the mounting shaft 16d is used as the first roller bearing 16c. A first support rail 24 provided on the middle of the upper cross beam 12a as shown in FIG.
The second support rail 25 receives the endless chain on its contact surface to distribute the weight and prevent the endless chain from sagging. In addition, 26 is a rail support member, and 26a is the same leg plate. A structure for distributing the weight and preventing sagging is also provided under the upper cross beam 12b. In addition, in order to prevent the vehicle cage 19 from shaking when it moves laterally along the upper cross beam 12a, as shown in FIG.
An auxiliary rail 27 is horizontally mounted parallel to the top of the rail 27.
A second
Three-point support with rollers 28a and 28b centering on a roller bearing 16C that rides on the support rail 25 prevents horizontal shaking.

FIG. 6 shows a second embodiment in which four vehicle-mounted baskets 19 are hung, and all the structures are the same as in the first embodiment.

<Effects of the Invention> Since the present invention is constructed as described above, a vertically long rectangular frame is formed in each of the first frame and the second frame, and chain foils are attached to the four inner corners of both angle frames. An endless chain is hung around the endless chain, and a hanging shaft is hung horizontally between the endless chains to suspend the car cage, and chain rollers and roller bearings are attached to the endless chain to provide first and second support during horizontal movement. Since it is supported by rails, the weight of the chain is distributed and borne when the vehicle cage is moved laterally, making the chain wheel and chain smaller and easier to manufacture and assemble in small and medium-sized equipment. This produces the effect that a multi-level parking lot can be formed.
