Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking lot for an automobile. More specifically, the present invention relates to a pallet on which an automobile is mounted on the ground. It relates to a device for moving in a direction.

[0002]

2. Description of the Related Art Conventionally, as a mechanical parking lot of this kind, a supporting wheel of a pallet is driven, a guide rail is laid only in the parking lot, and guidance is provided by a guide wheel provided on the pallet. , A free method is known.

[0003]

In the prior art, although the device is relatively simple, since the guide is free on the road, it may meander depending on the condition of the road surface, the load on the wheels, the wear of the wheels, etc. , It becomes difficult to return to the parking lot because the moving direction is incorrect.

Further, the road surface is lower than the parking scene, that is,
If there is a step at the boundary, a slope plate is installed at the step, but when passing through this part, the pallet tilts and there is a problem that it becomes unstable especially when a car is installed. Was.

The present invention has been made in view of the above-mentioned problems of the prior art, and the object thereof is to reliably guide the vehicle on the road and to make a step between the parking scene and the road surface. Therefore, it is an object of the present invention to provide a device which can be moved horizontally even if there is such a situation and does not require a guide rail to be laid on the road.

[0006]

In order to achieve the above object, a mechanical parking lot apparatus according to the present invention has a pallet section and a truck section provided with a drive unit separated from each other, and an upper side of a chain provided before and after the truck. Each point on the chain is connected to a pallet, and each point on the underside of the chain is fixed to the ground. The chain is driven by a motor attached to the trolley via a drive shaft extending in the front-rear direction.

Wheels (8) with flanges are attached to the trolley so as to be guided by rails mounted on the ground.

Guides are attached to the front and rear of the pallet so that the pallets can be guided from the front and rear surfaces of the trolley.

Further, the wheels (3) for supporting the pallet can be supported also from the upper surface of the carriage.

[0010]

[Operation] By rotating the motor, the force in the moving direction is transmitted to the front and rear chains via the drive shaft and the like, and the bogie with the fixed point as a reference is received by the reaction force from each front and rear points of the chain fixed on the ground. Is guided evenly in the front-rear direction and is guided from the side surface of the rail via the wheels, so that it reliably moves in the lateral direction without meandering.

Further, the pallet receives a force in the lateral movement direction from the connecting portion of the front and rear chains, and reliably travels straight in the lateral direction without meandering from the front and rear surfaces of the trolley via the guide.

The amount of lateral movement of the pallet is twice as large as that of the dolly, and the dolly only half penetrates the road. As a result, the fixed point between the chain and the ground is settled in the parking lot, and the pallet can be reliably guided even on the road without laying a guide rail or the like on the road.

Further, by supporting the wheel (3) supporting the pallet from the upper surface of the trolley, when there is a step between the parking scene and the road surface, the wheel (3, 8) is independent of the step. Has already been adjusted to the road surface, so
In the pallet, the step portion can also move horizontally.

【Example】

(Embodiment 1) An embodiment will be described with reference to the drawings. In FIGS. 1 to 3, a pallet 1 is formed with slope portions at both front and rear ends and at left and right ends so that a vehicle can be self-propelled and mounted. Has a convex portion over its entire length to prevent a falling wheel. The H dimension of the tip of the pallet 1 is about 3
Although it is 0 mm, when the automobile passes through this part, only the slope part of the pallet 1 swings around the hinge 19 so that the pallet 1 does not lift up due to the lever action with the wheel 2 as the fulcrum so that it will land. There is. After passing, it returns with a spring. Further, the wheels 2 and 3 for supporting the load from the ground, the guide 4 so as to be guided from the front and rear surfaces of the carriage 6 to prevent meandering during lateral movement, and the lateral movement force are obtained from the chain 15. A connecting metal fitting 5 is attached. The guide 4 is a roller type that rotates in the horizontal direction, but may be a sliding piece.

The dolly 6 has a rectangular frame made of shaped steel,
A wheel 7 for supporting a load from the ground and a wheel 8 with a flange are mounted so as to support the load from a rail 18 mounted on the ground and be guided from the side surface of the rail 18.

The drive device comprises a carriage 6, a motor 9, and a drive shaft 1.
3 and a sprocket 16 are supported, and the motor 9 and the drive shaft 13 are connected by a chain 11 via a sprocket 10 and a sprocket 12, and the drive shaft 13 and the sprocket 1 are connected.
6 are connected by chains 15 via sprockets 14.

Further, in order to obtain the reaction force of the lateral movement from the ground, the ground and the chain 15 are fixed by the fixing fittings 17.

When moving laterally, first, the motor 9 rotates,
The drive shaft 13 rotates via the sprocket 10, the chain 11, and the sprocket 12, and the chain 15 operates via the sprocket 14. The lower side of the chain 15 is a fixture 1
Since it is fixed to the ground by 7, the dolly 6 receives the reaction force from the fixing bracket 17 and moves laterally. Since the upper side of the chain 15 is connected to the pallet 1 by the connecting fitting 5, the pallet 1 also moves laterally while being guided by the guide 4 from the front and rear surfaces of the carriage 6.

FIG. 4 and FIG. 5 show the moved state. The moving distance of the pallet 1 is that the chain 15 operates on the moving carriage 6 and receives the moving force from the chain 15.
Move twice as much as a dolly.

(Embodiment 2) In FIG. 6 and FIG. 7, the wheel 3 for supporting the load of the pallet 1 and the guide 4 guided from the front and rear surfaces of the trolley to prevent meandering are integrated and the trolley upper surface is shown. It is a wheel with a flange that travels. Also,
The wheel and the guide are not integrated, but separated as shown in FIG.
It is also possible to simply change the wheel 3 from the ground surface to the support of the bogie surface. The trolley width L is made as large as possible in order to improve the stability of the pallet 1 when the vehicle is mounted.

(Embodiment 3) Further, in FIG. 7, the case where the road surface is lower than the parking scene by about 100 mm, that is, there is a step at the boundary, the lower surfaces of the wheels 2 and 7 are attached according to the road surface. ing. As a result, only the position of the wheel 2 and the wheel 7 in the parking lot causes the stepped portion to bite into the parking lot.

[0022]

Since the present invention is constructed as described above, it has the following effects.

The lower side of the chain is fixed to the ground via the fixing metal fittings, and the trolley is moved laterally by operating the drive device.
By connecting the upper side of the chain to the pallet via the connecting fitting, the pallet can be moved laterally.

By providing the chain, the fixing metal fittings, and the connecting metal fittings in the front and rear, the front and rear of the pallet can be evenly moved laterally.

Further, the carriage can be laterally moved without meandering by being guided from the rail side surface via the flange wheel and the pallet from the carriage side surface via the guide.

Further, since the lateral movement distance of the carriage is half that of the pallet, the pallet can be guided on the road surface without laying guide rails or the like on the road surface.

Also, by supporting the pallet wheels (3) on the upper surface of the dolly and by matching the supporting surfaces of the pallet wheels (2) and the trolley wheels (7) with the road surface, there is a step between the parking scene and the road surface. In some cases, the pallet can be moved horizontally.
