Description

[Detailed explanation of the invention] (a) Industrial application field The present invention is a vertical circulation parking system in which a pallet on which a car is mounted is removably mounted on a cage, and the front and rear of the pallet are moved at the lowest position of the cage. The present invention relates to a parking device in which a vehicle that has been parked in the forward direction is moved out of the parking lot by moving forward again.

(b) Conventional technology Conventionally, the cage of this type of parking device is provided with a through shaft at the center of the upper part for connecting the front and rear suspension rods, and this is used as the suspension shaft. In order to change the direction of the pallet by 180 degrees, it is necessary to lift the pallet and turn it.In order to prevent the above-mentioned through shaft from touching the top of the car on which it is mounted when it is lifted, leave an extra gap for the lift. I was making a cage.

(c) Problems to be solved by the invention Providing an extra gap as described above has the disadvantage that the height of the cage increases accordingly, which inevitably reduces the number of cages that can be accommodated.

(d) Means for solving the problem In order to improve the above-mentioned drawbacks, the present invention has been developed by installing a chain that is attached to the upper and lower sprockets and is driven in the axial direction of the sprocket in a hangar that has an entry/exit entrance at the bottom. The cage is configured to be circulated vertically by suspending a suspension shaft provided at the center of the upper part of the cage from a plurality of arms protruding from each chain. In a vertical circulation type parking device, a drive means for lifting and lowering the pallet and for turning the pallet is provided on the floor surface at the lowest position of the cage. A guide for supporting the rollers is provided over the entire straight part of the chain, and a floor frame that connects the cage with gate-shaped suspension rods arranged in the front and back when viewed from the axial direction of the sprocket and the lower part of the suspension rods. It is characterized in that it consists of a pallet that engages with the floor frame, and is suspended from an arm by a hanging shaft at the center of the upper part of each hanging rod, so that the upper part of the vehicle mounting surface is open.

(E) Effect Guide rollers are provided on both sides of the chain at the protruding part of the arm that suspends the cage, and guides that support the guide rollers are provided across the entire straight part of the chain so that the chain is sandwiched between the two guides. The swing of the chain is reliably prevented, and the position of the suspension portion of the cage on the arm is firmly held, so that the cage can be easily connected to the front and rear suspension rods formed in a portal shape when viewed from the axis of the sprocket. , and a floor frame that connects the lower part thereof, and can be suspended by each hanging shaft at the center of the upper part of the hanging rod, eliminating the need for a conventional through-shaft. Therefore, the upper part of the vehicle mounting surface is open. Because of this, there is no problem with lifting when turning in the lowest position, and the gate-shaped suspension rods only need to be high enough to allow cars to enter, and the height of the cage can be lowered to increase the number of cars that can be accommodated.

(F) Example An example of the present invention will be explained with reference to the drawings.
In Figures 1 and 2, 1 is a hangar with an entry/exit entrance at the bottom, and chains 3 stretched across upper and lower sprockets 2 and 2' are arranged in parallel in the axial direction of the sprockets. A cage 5 is suspended from a plurality of arms 4 protruding from the chain (the drive device, support device, etc. for the sprocket are not included in the drawings and are omitted from the drawings).

Next, in the enlarged detailed views of Figures 3 and 4,
Guide rollers 7 are provided on both sides of the chain link 6 having the arm 4, and guides 8 that support the guide rollers 7 are provided over the entire linearly stretched portion of the chain 3, and the outer guides 8 are directly supported from the hangar 1. 9, the inner guide 8 is supported from a connecting member 10 constructed by connecting both walls of the hangar 1 in the space between the left and right chains, which is out of the movement trajectory of the cage 5 when viewed from the axial direction of the sprocket. There is. Next, the sixth
In the figures and FIG. 7, the cage 5 is removably engaged with a floor frame 12 that connects a gate-shaped suspension rod 11 arranged at the front and back when viewed from the axial direction of the sprocket, and a floor frame 12 that connects the lower part of the suspension rod. A hanging shaft 14 provided at the center of the upper part of each hanging rod 11 is rotatably fitted into the tip of the arm 4, so that the upper part of the pallet 13 is open. Reference numeral 15 denotes a pallet turning device installed on the floor below the cage at the lowest position of the cage, in which a sprocket 18 of a turning plate 17 having four lifting cylinders 16 is turned by a chain 20 from a drive machine 19. There is.

(G) Effects of the invention As mentioned above, in this invention, the upper part of the vehicle mounting surface is open, so there is no problem in lifting the pallet when turning it at the lowest position, and the gate-shaped hanging rod has a height that allows the entrance of the vehicle. This is sufficient, and the number of cages that can be accommodated can be increased by lowering the height of the cage. Previously, the maximum number of cages that could be accommodated was 30 within the building height limit of 31m, which was restricted by the Building Standards Act. However, according to the present invention, it is possible to accommodate 32 to 33 cages, and by firmly holding the suspension part of the cage by sandwiching the chain between both guides, it can replace the conventional through shaft. Because of this, no extra force is applied to the cage and no deformation occurs.
