Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a turntable that is installed on the ground within a parking device that hoists and stores automobiles using a hawk.

(Prior Art) A turntable for changing the direction of a car installed in a hawk-type car parking device is a rotating hawk installed at a boarding area on the ground by lowering lifting platforms 1a and 1b on which cars are mounted. The vehicle was transferred to a stand 3 as shown in FIG. 8, and the rotating fork stand 3, which was supported by a fork stand fulcrum 9 and equipped with a drive unit, was rotated to change the direction of the automobile.

However, since there is a difference in the weight applied to the front and rear wheels of an automobile, there is a risk that the rotating hawk stand 3 will receive an uneven load and tilt, so the hawk type stand fulcrum 9 must have a strong structure. Turntables had become larger and more expensive.

In addition, when rollers are rotatably installed on the rotary fork stand 3, there is an intermittent passage 10 for lifting the lifting stands 1a and 1b, and when the rotary fork stand 3 rotates, the roller falls into the intermittent passage 10. The drawback was that the impact caused vibrations and noise.

(Problems to be Solved by the Invention) The present invention is a rotary fork stand 3 in which the drive device for the conventional strong and large fork stand fulcrum 9 is made more compact and smooth rotation is possible. To achieve this, the load on the rotary fork stand 3 is reduced by replacing the device of the fork stand fulcrum 9 that supports and drives the rotary fork stand 3 with a roller on the bottom of the rotary fork stand 3 to disperse each action. Supporting roller 6
a, 6b, 6c, 6d, and support rollers 6a, 6b, which are driven and rotated by the built-in motor Mb.
The mechanism based on 6c and 6d is adopted. Support roller 6
a, 6b, 6c, and 6d support the rotary fork stand 3 and run on the rotary fork stand rail 7 to rotate the rotary fork stand 3. In order to ensure smooth rotation, the intermittent passage 10 is closed and the integrated A continuous rail must be formed, which requires the use of plugs 8 to block the intermittent passages 10 in the rotating fork rail 7.
a and 8b are provided on the lifting tables 1a and 1b, so that when the lifting tables 1a and 1b are lowered from the rotary fork rail 7, the closing members 8a and 8b act.

It is an object of the present invention to solve the above-mentioned problems with the above-described configuration, and to provide a downsized hawk stand fulcrum 9 device and a turntable that can be rotated smoothly at low cost.

(Means for solving the problem) A rotary fork stand rail 7 provided with an intermittent passage 10 for passing the lifting stands 1a and 1b at the lower part of the rotary fork stand 3, a blocking material 8a for closing the intermittent passage 10,
8b is provided on the lifting platforms 1a and 1b so as to be able to move up and down,
The turntable is provided with a rotary fork stand 3 which can intersect with lifting stands 1a and 1b and is rotatable on a rotary fork stand rail 7 around a fork stand fulcrum 9.

Further, support rollers 6a, 6b, 6c, and 6d are provided on the bottom of the rotary fork stand 3 to support the load of the automobile, and the support rollers 6a, 6b, 6c, and 6d are moved on the fork stand rail 7 by a built-in motor Mb. It is provided so that it can be driven and rotated.

Then, a lifting platform 1 is placed at the bottom of the rotating hawk platform 3.
A fixed fork stand 12 which can intersect with a and 1b is provided, and when the rotary fork stand 3 is turned in the 90° direction, the lifting stands 1a and 1b and the fixed fork stand 12 are engaged.

(Function) Support rollers 6a, 6 that support the rotating hawk stand 3
b, 6c, 6d are provided on the bottom of the rotating hawk stand 3,
Support rollers 6a, 6b, 6c, 6d under load
rotates on the rotating hawk base rail 7. The rotating hawk stand rail 7 has an intermittent passage 10 through which the lifting tables 1a and 1b pass, and the intermittent passage 10 is blocked by blocking materials 8a and 8b provided on the lifting tables 1a and 1b, thereby creating an integral seamless rotating hawk. A platform rail 7 can be formed. Furthermore, support rollers 6a, 6
b, 6c, and 6d are driven and rotated by the motor Mb built in the rotary hawk stand 3, so the hawk stand fulcrum 9
can be made into just a simple fulcrum.

In addition, when the direction of the entrance of the car needs to be 90 degrees depending on the installation location of the parking device, if the fixed fork stand 12 is provided at the bottom of the rotating fork stand 3, the fixed fork stand 12 and the lifting stand 1a , 1b can form an integrated safe passageway, allowing cars to enter from a 90° direction.
It can be used as a passageway for people.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. In Fig. 1, 1a is the left lifting platform, 1b is the right lifting platform, 2 is the wire or chain (hereinafter simply abbreviated as wire) that suspends the lifting platforms 1a and 1b, and Ma is the wire or chain that suspends the lifting platforms 1a and 1b. Lifting platform 1a, 1
The motor Ma raises and lowers the lifting platforms 1a and 1b horizontally at the same speed. 3 is a rotating hawk stand, and the lifting stand 1a,
Hawk 1 intersecting with Hawk 11 fixed to 1b
1, and is set at the same height as the ground level and serves as a boarding area for cars.

P is a pit so that the lifting tables 1a and 1b can be lowered, and in FIG. 2, Mb is a motor that rotates support rollers 6a and 6b built into the rotary fork table 3 to rotate the rotary fork table 3. Figure 1,
In Fig. 7, reference numeral 5 denotes a transverse storage trolley which is stored in each layer and equipped with a hawk 11 on which a car can be placed, and which moves transversely on the beam 4 and can intersect with the lifting platforms 1a and 1b, allowing the delivery of cars. ing. The support rollers 6a, 6b, 6c, 6d are the lifting tables 1a, 1
b descends from the rotating hawk rail 7 and enters the intermittent passage 1.
0, the blocking members 8a and 8b provided on the upper surfaces of the lifting platforms 1a and 1b as shown in FIG. 6 close the intermittent passage 10 as shown in FIG. is formed as shown in Figure 3.
The closing members 8a and 8b are iron plates that close only the cuts in the rotary hawk platform rail 7. A plurality of guide rods are attached to the bottom surface of the iron plates, and vertical movement is made through the through holes provided on the top surface of the lifting platforms 1a and 1b. Possibly inserted. After the blocking materials 8a and 8b form a continuous rotating fork rail 7, the rotating fork stand 3 is rotated about the fork stand fulcrum 9 by driving of the support rollers 6a and 6b as shown in FIG.

To explain the operation of the rotary fork stand 3 in the process of taking out a car, it moves the accommodated transverse storage cart 5 transversely to the lifting-like space in the center of FIG.
The lifting platforms 1a and 1b, which formed a path integrated with the rotary hawk platform 3 on the ground surface, rise to receive the car placed across the transverse storage trolley 5, and the transverse storage trolley 5 returns to its original position. When returning to , the lifting platforms 1a and 1b that received the car are lowered and intersect with the rotary fork stand 3, so that the car can be placed on the rotary fork stand 3. When the lifting platforms 1a and 1b are lowered to a position below the rotary fork base 7 and the intermittent passage 10 is closed with the blocking materials 8a and 8b to form an integrated rotary fork base rail 7 as shown in FIG. 5, the motor Mb stops rotating. When the rotary fork stand 3 rotates while being supported by the support rollers 6a, 6b, 6c, and 6d, the lifting stands 1a and 1b rise to a position where they are integrated with the rotary fork stand 3, forming a passageway through which people can safely pass. .
The driver can get into the car and drive it forward from within the device to easily get out of the car, and the car is ready to leave the garage.

In this embodiment, the closing members 8a and 8b are lowered by their own weight, but a method may also be adopted in which a coiled spring (not shown) is attached to forcibly accommodate the closing members 8a and 8b.

Alternatively, as shown in FIG. 9, there is also a method of supporting vertical movement along the side surfaces of the lifting tables 1a and 1b.

In the embodiment shown in FIG. 10, the rotary fork stand 3 is rotated so that vehicles can enter and exit the garage not only in the direction of arrow A but also in the directions of arrows B and C depending on the land situation. For entry and exit from the warehouse from the directions of arrows B and C, the fixed fork stand 12 provided at the bottom of the rotating fork stand 3 is located perpendicular to the rotating fork stand 3, and the fork 11 of the lifting stands 1a and 1b and the fixed fork stand 12 The hawks 11 of the two mesh with each other to form an integral passage, allowing a person to pass through the hole.

(Effect of the invention) As explained above, when the lifting tables 1a and 1b deliver the car to the rotary hawk table B, the blocking material 8
a and 8b close the intermittent passage 10 and form a continuous rotating fork rail 7, so that the support roller 6
a, 6b, 6c, and 6d can rotate smoothly. Since the load applied to the rotary fork stand 3 is distributed and supported by the support rollers 6a, 6b, 6c, and 6d, and the support rollers 6a, 6b, 6c, and 6d are driven and rotated, it is necessary to strengthen the fork stand fulcrum 9 with a complicated structure. Since the bending moment is small, it can be made compact and inexpensive, and since the rotation is smoother, the rotation speed can be increased.

In addition, since the rotary fork stand 12 is provided, it is possible to board the car from not only one direction but from three directions, which is very convenient, and the fixed fork stand 12 and the lifting stands 1a and 1b mesh to form a passage for people. So you can get on and off safely.
