Abstract

PURPOSE: To make rotation of a rotating fork table smooth by closing intermittent passages of a rotating fork table rail serving as a passage of a plurality of support rollers of the rotating fork table, with closing members to make a plurality of support rollers rotatable on the rotating fork table rail. CONSTITUTION: A rotating fork table rail 7 is provided as a passage of support rollers 6a, 6b, 6c, 6d of a rotating fork table 3 with its upper face flush with the ground surface. Intermittent passages 10 of the rotating fork table rail 7 are closed with closing members 8a, 8b fitted to lateral lifting tables 1a, 1b to make the support rollers 6a, 6b, 6c, 6d provided at the rotating fork table 3 rotatable on the rotating fork table rail 7. Load applied to the rotating fork table 3 is received by four support rollers 6a, 6b, 6c, 6d to reduce the inclination of load. Rotation of the rotating fork table when placing an automobile can therefore be made smooth and stable.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to a turntable installed on the ground surface of a parking lot where automobiles are hoisted and stored using a hawk.

(b) Problems to be solved by conventional technology and inventions.

In conventional car parking lots where cars are hoisted and stored on storage bases, turntables are used to change the direction of cars on the ground. However, in order to change the direction of the car at the position where the car has descended to the ground, the car is mounted on the rotary fork stand 3 as shown in Fig. 8, and the rotary fork stand 3 is supported by the fork stand fulcrum 9. However, due to the location of the center of gravity of the car, the load placed on the rotating hawk stand 3 caused it to tilt, which required a strong structure. Even if the rotating fork stand 3 is provided with auxiliary rollers, etc., the rotating fork stand 3 will be unstable and rotate smoothly when it passes through the intermittent passage 10 for raising and lowering the left and right lifting stands 1a and 1b. I couldn't do it.

(1) Means and operation for solving the problems In order to solve the above-mentioned problems, the present invention will be explained with reference to FIG. 2 of the embodiment.
6c and 6d are installed, and blockers 8a and 8b as shown in FIG. 6b, 6c, 6d rotate and rotate,
6c and 6d reduce the slope of the receiving load.

This solves the above-mentioned problems.

(1) Example The present invention will be explained in detail with reference to the following drawings. 1a is a left lifting stand, 1b is a right lifting stand, 2 is a left and right lifting stand 1a.
, 1b, a wire or a check 2 (hereinafter simply abbreviated as wire) Ma winds up this wire 2 and uses it as a motor for lifting the left and right lifting platforms 1a and 1b, and by driving this Ma. The left and right lifting platforms 1a and 1b are always kept at the same speed and the same height, and move up and down in the center elevator space of this parking device. 3 is a rotating hawk stand, and a hawk that intersects with both the hawks on the left and right lifting stands 1a and 1b is attached.

The upper surface of this rotary hawk stand 3 is at the same height as the ground surface. p is a bit, and Mb is a support roller 6a.

This is a motor that rotates the rotary hawk stand 3 by rotating the rotary hawk stand 3. 4
is a beam and 5 is a transverse storage cart, so that the transverse storage cart 5 of each layer can traverse the beam of each layer. Note 4
As shown in FIGS. 1 and 6, the main wire 2 is mounted on a lifting platform 1a on the outside of the front and rear beams 4.

1b is lifted, so that the rotating hawk stand 3 does not come into contact with the wire 2 and can rotate freely. Moreover, as shown in FIG. 2, the support rollers 6a, 6b, 6c, and 6d are
Left and right lifting platforms 1a and 1b on the rotating hawk platform rail 7
Since the intermittent passageway 10 cannot be crossed, the blocking materials 8a and 8b attached to the left and right lifting tables 1a and 1b are the left and right lifting tables 1a.

When the lb is lowered from the rotary hawk stand 3, the blockers 8a, 8
Install multiple guide rods below b.

A closing material 8a is placed at the position of the gap 10 of the rotary fork rail 7.
, 8b are placed on the left and right lifting platforms 1a.

A hole is made in 1b for the guide rod to pass through so that it can be moved up and down. As shown in Fig. 5, the left and right lifting platforms 1a, 1b
The blocking members 8a and 8b are installed to close the intermittent passages 10 of the rotary fork stand rail 7 so that the rotary fork stand 3 can easily move on the rotary fork stand rail 7. Moreover, the closing members 8a and 8b are attached with a plurality of guide rods, and the left and right lifting stands 1a.

When 1b rises, gravity lifts the left and right lifting platforms 1a.

A plurality of guide rods are guided to the passage provided in 1b. Moreover, the closing members 8a and 8b are the left and right lifting platforms 1a.

When 1b descends from the rotary hawk stand 3, the closing members 8a, 8
b comes out from the passage provided on the left and right lifting tables 1a, 1b with a plurality of guide rods, and is placed on the rotary hawk stand rail 7 precisely at the position where the blocking material is placed.In this embodiment, the method using its own weight is used. I took it.

Alternatively, a coiled spring (as shown) may be attached to the closing members 8a, 8b to force the closing members 8a, 8b to be housed in the left and right lifting stands 1a, 1b.

In addition, the closing materials 8a and 8b are attached to the left and right lifting platforms 1 as shown in FIG.
There is also a method of covering the sides of a and 1b. With this method, the left and right lifting platforms 1a.

There is no need to weaken the strength by drilling holes in 1b.

In the embodiment (2), the sprocket foil (as shown) attached to the bottom of the rotary hawk stand 3 supported by the hawk stand fulcrum 9 meshes with the gear of the drive shaft of the motor (as shown) and is driven by this motor. The rotating fork stand 3 has support rollers 6a, 6b, and 6c.

6d and rotates on the rotating hawk stand rail 7 to change the direction of the vehicle.

In the embodiment (2), as shown in Fig. 9, the rotary fork platform 3 is changed so that vehicles can enter and exit the door not only from the direction of arrow A but also from the direction of arrow B or C depending on the land situation. When entering and exiting in the direction of arrow C, the fixed fork stand 12 provided at the bottom of the one-turn fork stand 3 rotates seven times for the fork stand 3.
The hoes 7 of the left and right lifting stands 1a and 1b intersect with the hoes 7 of the fixed fork stand 12, thereby reducing the gap. Furthermore, when entering in the A direction, the rotary fork stand 3 and the fixed fork stand 12 overlap, and the hoes 7 of the left and right lifting stands 1a, 1b intersect with the hoes 7 of the rotary fork stand 3 to reduce the gap.

(e) As explained in detail about the invention, when a car is placed on the rotating hawk stand, it can rotate smoothly because the intermittent passages 2 are blocked;
Since the load is distributed among the wheels, it is possible to obtain smooth and stable rotation and increase the rotation speed.The rotating hawk support fulcrum does not require a complicated structure, and the bending moment is small, resulting in less strength. A significant effect can be obtained in terms of manufacturing costs.

In addition, those equipped with a fixed fork stand are very convenient as they allow vehicles to enter and exit from three directions instead of just one direction.The distance between the left and right lifting stands and the fixed fork stand is small, making it easier for car drivers to enter and exit the garage. and allow passengers to get on and off the vehicle safely and easily.

It has a great effect.
