Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a parking device, and particularly to a two-stage parking device.

[Conventional technology]

Conventionally, a parking device is provided with a pallet that is movable up and down and on which a car can be parked, and in which another car can be parked at a position below the pallet while the pallet is raised. The four corners of the pallet were lifted by four wires or other filaments, and each filament was wound onto a separate winding drum and raised and lowered.

[The problem that the idea attempts to solve]

The conventional technology described above has the problem that the mechanism for winding and unwinding the filament is complicated, prone to failure, and difficult to maintain.Furthermore, each filament is driven independently. Therefore, it was difficult to synchronize the pallets, and there was a risk that the pallets would tilt during vertical movement.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a parking device in which a car parked on a pallet is held in a stable position without tilting the pallet when the pallet moves up and down.

[Means to solve the problem]

In order to achieve the above object, the parking device of the present invention includes a vertically movable pallet on which a car can be parked, and when the pallet is raised, other cars can be parked at a position below the pallet. In the parking device, a pair of left and right endless chains that are interlocked by a drive motor is disposed at the top, and a pair of chains that move in opposite directions along the horizontal direction by the drive of the chains are provided. The connecting portion is provided with a connecting portion, and the connecting portion and the pallet are connected via a direction changing mechanism with a connecting member made of a linear body such as a chain or a wire, and the horizontal direction of the connecting portion by driving the chain is When moving, the pallet is moved up and down along the vertical direction. Further, the direction changing mechanism preferably includes a movable pulley or a movable chain wheel attached to the pallet.

[Effect]

When the drive motor is driven, each chain is driven and the pallet moves up and down, but in this case, all the connecting members are driven at the same time and the amount of movement of the connecting parts is the same, so the pallet When moving up and down, the pallet does not tilt.

Furthermore, if the direction changing mechanism is equipped with a movable pulley or a movable chain wheel attached to the pallet, the amount of movement of the connecting portion can be sufficiently large compared to the amount of vertical movement of the pallet, and the amount of movement of the connecting portion can be sufficiently large to drive the connecting member. The drive motor can be made smaller.

〔Example〕

Examples will be described below with reference to the drawings.

Fig. 1 and Fig. 2 show an embodiment of the parking device according to the present invention. It is equipped with a pair of left and right upper frames 2, 2, and a pallet 4 that is movable up and down between the supports 1, and a car can be parked on the pallet 4. In the elevated state, other cars can enter the lower position of the pallet 4 and park.
2), an endless chain 5 arranged in
By driving the chain 5, the pallet 4 is moved up and down via a connecting member 6 that connects the chain 5 and the pallet 4.

The left and right upper frames 2, 2 are hollow with a rectangular tube shape or a C-shaped cross section, and pivotally support rotating shafts 7, 7 disposed at the front and rear. Sprockets 8, 8 are fixed to the left and right ends of the rotating shafts 7, 7, and chains 5, 5 are attached to the sprockets 8, 8.

When rotated, the pair of connecting parts 10, 10 move in opposite directions. That is, the pair of connecting members 10, 10 are provided at point-symmetrical positions when viewed from the side.

A drive motor 13 is attached to the rear part of the left upper frame 2 via a bracket 12, and the chain 5 is rotationally driven by the drive of the motor 13. That is, a motor sprocket 15 is provided at the tip of the rotating shaft 14 of the motor 13, and a rotating shaft sprocket 16 is provided at the rear rotating shaft 7.
A chain 17 is suspended between the sprockets 15 and 16.

Therefore, when the rotating shaft 14 of the motor 13 rotates, the rear rotating shaft 7 rotates, the chain 5 rotates, and the front rotating shaft 7 rotates.

The other end 18 of each connecting member 6 is connected to the support column 1 via a direction changing mechanism 19, so that when the chain 5 is rotated, the pallet 4 moves up and down.

In addition, the direction changing mechanism 19 is provided in four pieces on the front, back, left, and right, and the rear one includes a fixed pulley 20 arranged at the rear of the upper frame 2 and a fixed pulley 20 arranged at the upper end of the rear column 1. a pulley 21; a movable pulley 22 attached to the pallet 4 and contained within the support 1;
a fixed pulley 23 disposed behind the fixed pulley 21 and at the upper end of the support column 1;

For example, the direction changing mechanism 19 may be provided without the movable pulley 22. In this case, The movable pulley 22, fixed pulleys 23, 31, and connectors 24, 24 are omitted,
The other end 18 of the connecting member 6 is directly fixed to the pallet 4. Therefore, in this case, the amount of movement X of the connecting portion 10
The amount of movement of pallet 4 is the same.

Further, if the connecting member 6 is a wire, the direction changing mechanism 19 is composed of a pulley as shown in the figure, but if the connecting member 6 is a chain, the direction changing mechanism 19
A chain wheel is used instead of a pulley.

[Effect of idea]

In the parking device of the present invention, the amount of movement of each connecting part is the same, ensuring synchronization, and when the pallet 4 moves up and down, the pallet 4 does not tilt and maintains a horizontal state smoothly. It will move up and down,
A car parked on the pallet 4 is held in a stable position. Furthermore, the structure can be made extremely simple, and it is difficult to break down.

Furthermore, if the direction changing mechanism 19 is equipped with a movable pulley 22 or a movable chain pulley attached to the pallet 4, the drive motor 13 for moving the pallet 4 up and down can be made smaller. In this case as well, the length of the upper frame 2 and the like need only be approximately equal to the length of the parked car, and the overall volume of the installation location does not increase.
