Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a turntable for changing the direction of an automobile attached to an entrance / exit of a vertical circulation type multi-storey car park, for example.

<< Prior Art >> For example, as disclosed in Japanese Patent Laid-Open No. 63-44083, a turntable for turning a vehicle of this type is provided with a traverse carriage that moves along a rail on the turntable. A device is known in which not only the vehicle mounted on the top is rotated by a turntable, but also a transverse carriage is driven to move the vehicle in the width direction.

<Problems to be solved by the invention> The purpose of providing a lateral shift mechanism on a turntable for direction change is to change the course of the vehicle in the width direction as in the above-mentioned prior art, and to set the vehicle on the centerline of the turntable. There may be a case where fine adjustment is performed to align the center lines of the two. For the latter purpose, the lateral shift amount may be small. However, in the conventional configuration in which a large-scale traverse cart is added on the turntable, the mechanism becomes complicated, the entire device becomes large, and the cost increases significantly.
It was not an appropriate lateral shift mechanism for the latter purpose.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to make it possible to perform operations such as slightly moving the vehicle in the width direction on the turntable to align the centers, and the like. It is to provide an inexpensive lateral shift mechanism.

<< Means for Solving the Problem >> Therefore, in this invention, the reference position on the turntable,
A large number of rollers having a diameter sufficiently smaller than the tire width are arranged in parallel at appropriate intervals in the front-rear direction of the vehicle at the portion where each tire of the vehicle arranged in the reference direction contacts the ground. Then, the rollers are configured to be retractable from the surface of the turntable, and a retracting / retracting drive mechanism for driving the rollers in and out and a drive mechanism for rotationally driving the rollers in the same direction are provided.

<< Operation >> When the vehicle is stopped on the turntable in accordance with the reference position and the reference direction on the turntable, each tire is grounded at the portion where the roller is arranged. In this state, after the roller is projected from the surface of the turntable by the retractable drive mechanism and then the roller is driven to rotate in the same direction by the rotary drive mechanism, the automobile is displaced in the width direction on the turntable according to the rotation of the roller. . After that, when the roller is retracted from the surface of the turntable by the retracting drive mechanism, each tire is grounded on the surface of the turntable, and the load of the automobile in the stopped state is not applied to the roller.

<< Embodiment >> FIGS. 1 to 3 show an embodiment of the present invention. FIG. 1 is a plan view of a turntable 1 having a shift mechanism according to the present invention. The turntable 1 is rotationally driven on a horizontal plane by a well-known turning drive mechanism. P is a centerline indicating the reference position and the reference direction of the turntable 1, and the driver of the vehicle runs the vehicle so that the centerline of the vehicle and the centerline P of the turntable 1 are aligned with each other. Place the car in. At this time, if the driver's driving skill is inadequate, the position of the vehicle cannot be correctly aligned with the center line P, but in that case, the lateral shift mechanism of the present invention displaces the vehicle in the width direction to move the vehicle position. Correctly align with the center line P.

When the vehicle is placed on the turntable 1 roughly aligned with the center line P of the turntable 1 as a reference,
The four tires of the car have left and right lateral shift mechanisms 2a and 2b
Located on top. The configurations of the lateral shift mechanisms 2a and 2b are exactly the same and are as shown in FIGS. 2 and 3.

The lateral shift mechanisms 2a and 2b include a large number of rollers 4 having a diameter sufficiently smaller than the width of the tire 3 of the automobile. Each roller 4 is arranged in the groove 5 of the turntable 1 and
It is supported in the following manner at a predetermined interval in parallel with the center line P of.

A shaft protruding from both ends of the roller 4 is supported by a bearing unit 6 arranged in the vehicle width direction. This bearing unit 6 is attached to the turntable 1 side through an elevating cylinder 7 as a retractable drive mechanism. By expanding and contracting this cylinder 7, each roller 4 moves up and down in parallel with the turntable 1 together with the bearing unit 6. To do. Cylinder 7
When the bearing unit 6 is located at the lowest position by the
As shown by the dotted line in the figure, each roller 4 is completely set in the groove 5 and is in a state of being recessed from the upper surface of the turntable 1. On the contrary, when the drive unit 6 is positioned at the uppermost position by the cylinder 7, the upper surface side of the roller 4 is located on the turntable 1 side.
Is projected from the upper surface of.

As shown in FIG. 2, a gear 8 is attached to the shaft end of each roller.
, And the gears 8 of the adjacent rollers 4 are connected by an intermediate gear 9. Further, a sprocket 10 is attached to the shaft end of a predetermined one roller 4, and a chain 13 is hung between the sprocket 12 of the output shaft of a drive motor 11 as a rotary drive mechanism mounted on the bearing unit 6. It has been passed. In this configuration, when the motor 11 is rotated in a certain direction, each roller 4 is passed through the sprocket 12, the chain 13, the sprocket 10, the gear 8 and the intermediate gear 9.
Rotate in the same direction at the same speed.

The operation of the turntable 1 including the lateral shift mechanisms 2a and 2b configured as described above will be described in detail below.

Normally, each roller 4 is lowered by the cylinder 7, and the automobile is placed on the turntable 1 in that state.
When the vehicle mounted on the turntable 1 is displaced from the reference center line P, first, the cylinder 7 is driven to move the rollers 4 upward, and the tires 3 of the vehicle are slightly lifted by the rollers 4. The state (state shown by the solid line in FIG. 3). In this state, when the motor 11 is rotated in the predetermined direction (the direction for correcting the deviation), the rollers 4 all rotate in the same direction, and the automobile on which the tire 3 is mounted moves in the width direction as a whole. However, the position can be aligned with the center line P. When the position is corrected, the roller 4 is retracted downward again by the cylinder 7.

In the above-described embodiment, the roller 4 is moved up and down on the upper surface of the turntable 1 by the elevating drive mechanism. However, the elevating drive mechanism may be omitted and the tire of the automobile may be always grounded on the roller.

<Effect of Device> As described in detail above, in the turntable according to the present invention, a large number of rollers are arranged at predetermined positions on the turntable, and the rollers are driven to rotate in the same direction, thereby making the automobile on the roller. Since it is configured to move in the width direction, the entire configuration is much simpler and smaller than the conventional device that horizontally traverses the vehicle by mounting the traverse vehicle on the turntable while keeping the vehicle on the traverse vehicle. It is possible to reduce the price as well as the price.
