Description

ROTARY PARKING APPARATUS HAVING TURNTABLE

Technical Field The present invention relates to a rotary parking apparatus having a turntable, and more particularly, to a rotary parking apparatus having a turntable which is installed in the lower portion thereof, and rises by a plurality of hydraulic cylinders in which a plurality of carriers are rotated by 180 degrees by a hydraulic motor to thereby park a number of vehicles in the parking apparatus and take the same out therefrom conveniently, prevent the parking apparatus from vibrating and shaking and to thus heighten safety, and save an installation space.

Background Art

In general, when houses or buildings are newly constructed, predetermined parking spaces should be provided for according to the architectural code regulation. Thus, when houses or buildings are newly constructed, adeguate spaces are assigned into parking spaces. Usually, the underground spaces of houses or buildings, the whole first floor thereof, or the lateral spaces thereof are used as parking spaces. However, since a space utilization rate of the spaces which can be used in the houses or buildings falls, a parking facility may be provided in a separate space. There are various kinds and forms of the separate parking facility. Among them, the rotary parking apparatus is formed of a structure with a frame in which a plurality of carriers for individually parking vehicles are provided. Here, the carriers are circulated in an elliptical form so that a number of vehicles can be parked. The rotary parking apparatus is installed at a predetermined area of a site in the form of a parking tower, and can be continuously heightened in order to increase the number of vehicles which can be parked. As a result, since the space is saved, and the operation is simple, the rotary parking apparatuses are widely being used.

In the case of a general rotary parking apparatus, a vehicle is forwardly parked in and backwardly parked out, to accordingly cause lots of inconveniences. In order to solve the inconveniences y a turntable is installed at the outside of the rotary parking apparatus, for changing the location of the vehicle which is placed on the turntable by 180°. After the location of the vehicle has been changed, the vehicle should be backwardly parked. That is, the vehicle should be backwardly driven by a driver so as to be parked in place. According to Korean Utility Model Registration No. 0329557 entitled "Rotary parking apparatus having a built-in turntable, " the turntable is formed below carriers in the rotary parking apparatus. Here, the turntable is circular and includes a sawtooth portion formed along the inner diametric portion and rotation hydraulic cylinders installed along the circumference of the inner diametric portion. Accordingly,the turntable is rotated by the subsequently installed rotation hydraulic cylinders. As a result, since a number of the rotation hydraulic cylinders should be installed and the rotation hydraulic cylinders should be sequentially operated in sequence, a hydraulic circuit becomes complicated, and a counter-rotation may occur. In addition, since each carrier is lifted up and rotated out of the center of gravity in the turntable, a number of vibrations and much noise may occur and a problem in stability of the rotary parking apparatus may be caused.

Moreover, an electronic locking device is positioned on the upper portions of the respective carriers. Thus, the electronic locking device includes the axis of rotation in which a locking pin is inserted into a fixing groove in order to avoid any movement and rotation except when the carriers rotate. Here, since only a single locking pin is used, the carriers are not effectively prevented from the slight movement and rotation. In addition, when a vehicle is parked in the rotary parking apparatus, a parking location has to be determined as the eye measure. Accordingly, the weight of the vehicle is not accurately distributed in the carriers . As a result, when the carriers rotate in the rotary parking apparatus, they may be easy to shake.

Disclosure of the Invention To solve the above problems, it is an object of the present invention to provide a rotary parking apparatus having a turntable which is installed in the lower portion thereof, and rises by a plurality of hydraulic cylinders in which a plurality of carriers are circulated along an elliptic guide rail and rotated by 180 degrees, to thereby park a number of vehicles in the parking apparatus and take the same out therefrom conveniently, and save an installation space which is needed to install the rotary parking apparatus .

Hereinbelow, a rotary parking apparatus according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The present invention provides a rotary parking apparatus having a turntable which is installed in the lower portion thereof, and rises by a plurality of hydraulic cylinders in which a plurality of carriers are rotated by 180 degrees by a hydraulic motor to thereby park a number of vehicles in the parking apparatus and take the same out therefrom conveniently, prevent the parking apparatus from vibrating and shaking and to thus heighten safety, and save an installation space.

In more detail, referring to FIGS. 1 through 3, the present invention provides rotary parking apparatus including: a number of carriers 20 for parking respective vehicles, each of the carriers 20 having a pallet 21, a number of hangers 28 which are fixed to the pallet 21, and a supporter 25 supporting the hangers 28; an outer body 10 formed of main frames 11 in which connection plates 14 are connected with main chains 13 which rotate by a driving motor 12 at a certain interval and the number of the carriers 20 are fixed on the respective connection plates 14; and a turntable 50 which includes a ring-shaped inner ring 53 which is coupled along the inner circumference of the outer ring 52 by means of bearings 52b, in which a number of hydraulic cylinders 51a operating up and down are fixed on the inner ring 53, and a gear-box 53b' which is engaged with the outer ring 52 and a hydraulic motor 53b which drives the gear-box 53b' are installed in turn in the inner ring 53. Here, the turntable 50 is installed on the bottom of the outer body 10. When a vehicle 1 is parked on a standby empty carrier 20, the turntable 50 rises up and rotates to thus make the vehicle rotate by 180 degrees. Then, the carrier 20 moves by the driving motor 12 to thus allow a next standby empty carrier 20 to be ready to park a vehicle thereon.

That is, the rotary parking apparatus according to the present invention includes a number of the carriers 20 for parking respective vehicles, the outer body 10 which makes the carriers 20 rotate along a guide rail 15, and the turntable 50 which is installed on the bottom of the outer body 10 to then lift the carrier 20 and make the carrier 20 rotate by 180 degrees. Each component of the rotary parking apparatus will be described below in more detail with reference to the accompanying drawings.

Referring to FIGS. 1 to 3, main chains 13 rotating up and down by the driving motor 12 are provided in the inner sides of a structure formed of the main frames 11. A number of plate-shaped connection plates 14 are fixed along the main chains 13 at a certain interval, more particularly accurately, as many as a number of the carriers to be installed, in which the respective carriers 20 are fixed on the connection plates 14.

Moreover, guide rails 15 each having a C-shaped cross-section are fixed on one side of the main frames 11 in the form of a substantial arc. The guide rails 15 play a role of guiding roller 22b fixed to the carriers 20 to be described later, and are formed along the trail point according to the number and location of the rollers 22b. The guide rails 15 are generally located at the back side of the rotary parking apparatus.

Then, the carriers 20 for supporting and accommodating individual vehicles 1, respectively, will be described with reference to FIG. 1. As shown in FIG. 1, a carrier 20 includes a palette 21 accommodating a vehicle 1, a supporter 25 supporting the palette 21 and hangers 28 connecting the supporter 25 and the palette 21. Here, the pallet 21 is formed to have a certain area on which a vehicle is parked, in which a protruding portion 21' protrudes along an intermediate portion of the lengthy direction of the pallet 21 and a portion excluding the protruding portion 21' is sloped at both ends of the lengthy direction of the pallet 21, to thereby allow a vehicle to easily come in and out from the pallet 21.

Referring to FIGS .5, 16 and 17, two plate-shaped damper boards 21a of FIG. 17 are formed on the bottom of the protrusion 21', in the longitudinal direction thereof. The guide 21b is installed inwards from the two damper boards 21a. The guide 21b is made of a shape steel of an angle of a certain angle or a triangle section, in which the lower side of the guide 21b is pointed, that is, the cross-section of the guide 21b becomes narrow as it goes to the lower side. One or more rollers 21c are installed at appropriate places on the bottom of the pallet 21, as many as the number of the hangers 28 to be described afterward. The hangers 28 prevent collision between the adjacent carrier 20 and the hanger 28 when the carrier 20 moves along the guide rail 15, in consideration of a proper trail point of the carrier 20. Referring to FIGS. 4 and 5, the supporter 25 includes a lengthy supporting frame 22, a catching piece 23 of a ^--shaped cross-section where a penetrated catching hole 23a is formed, an assistant plate 24 on both ends of which a concave catching groove 24a is formed, respectively; and locking pins 25a and 25 ' of a certain shape. Both sides of the supporting frame 22 are fixedly connected with the connection plate 14. A guide frame 22a of a U-shape or linear form is fixed on one side of the supporting frame 22. The rollers 22b are fixed in the respective corners of the guide frame 22a. The rollers 22b roll and move along the guide rails 15, respectively. Moreover, as shown in FIG. 7, catching pieces 23 each of a ^--shaped cross-section are opposingly fixed in the longitudinal direction. The assistant plates 24 are formed of a certain area and is assembled with the catching pieces 23 with the assistant plate hung on the catching piece. The supporting frame 22 and the assistant plate 24 are fixed to the central rotating axis 25a. Accordingly, the assistant plate 24 can rotate with respect to the supporting frame 22.

Since the assistant plate 24 can rotate with respect to the supporting frame 22, the rotary parking apparatus has a locked state except when a vehicle is parked in and out. Referring to FIGS. 5 to 9, concave catching grooves 24a are formed at both ends of the assistant plate 24, and penetrated catching holes 23a are formed in the respective catching pieces 23. The locking pins 25a and 25a ' are provided in which the locking pins 25a and 25a' are fitted into the catching hole 23a and the catching groove 24a to thus make the position of the assistant plate 24 fixed. If the locking pins 25a and 25a' are disassembled and the assistant plate 24 is lifted in-between the catching pieces 23, the turntable 50 rotates based on the rotational axis 25 again. In addition, a method of locking and unlocking the locking pins 25a and 25a' will be described below. A link 25c and a wire 25c ' are connected with the locking pins 25a and 25a ' , respectively, in which a pulley 25d is installed at the side where the wire 25' is installed, to thereby wind the wire 25c' connected to the locking pin 25a' around the pulley 25d to thus change direction of the wire 25c' by 180 degrees so as to be connected to the link 25c connected with the other locking pin 25a. Thus, when the link 25c is pulled to thus pull the two locking pins 25a and 25a' simultaneously, and unlock of the locking pins 25a and 25a'. It is preferable that a spring 25e is formed between the link 25c and the wire 25c' , in order to mitigate impact which may occur in the rotary parking apparatus.

The rotary parking apparatus further includes an electronic locking and unlocking apparatus 30 for locking and unlocking the locking pins 25a and 25a', in order to pull the locking pins 25a and 25a'. Referring to FIGS. 9 to 11, the electronic locking and unlocking apparatus 30 includes a touch board 25f of a good electric conductivity certain area which is integrally formed at the end of the link 25c. The electronic locking and unlocking apparatus 30 is fixedly installed in the main frames 11. Inmore detail, the electronic locking and unlocking apparatus 30 includes a fixing portion 31 and a movable portion 33. The fixing portion 31 has a U-shaped lateral cross-section which is fixed to a main frame 11 opposing the touch board 25f in which the hydraulic cylinder 32 is fixed on the outer side of the fixing portion 31. The movable portion 33 moving to the hydraulic cylinder 32 is fixed by the fixing portion 31 in order to fix an electromagnet 36 on the movable portion 33, and forms an upper bracket 33a of plate material in the upper portion thereof, and a fixing bracket 33b and a lower bracket 33c which are integrally formed at a certain position and an intermediate portion of the lower portion thereof. Accordingly, the movable portion 33 has a modified τ-+n-shaped lateral cross-section. The electronic locking and unlocking apparatus 30 includes a touch pin 37 which is fitted into the electromagnet 36 so that the touch pin 37 protrudes from both ends of the electromagnet 36, and a contact limit switch 38 and an arrival limit switch 39 which are fixed on the movable portion 33 in sequenpe in addition to the touch pin 37.

A number of guide pins 35 are fitted with the lower bracket 33c in the movable portion 33. Both ends of each guide pin 35 are hung on and fixed to the fixing portion 31, respectively. A return spring 34 is fitted around the hydraulic cylinder 32 which is fixed to the fixing bracket 33b. A rod 32a is fixed to the fixing portion 31. A hydraulic hose 32b is connected to the rod 32a to supply the fluid. Accordingly, the hydraulic cylinder 32 moves and is returned to an original position by the return spring 34. The electromagnet 36 is fixed on the outer surface of the upper bracket 33a, and the touch pins 37 are protruded to the other sides of the electromagnet 36 and the upper bracket 33a via the penetrated holes. In addition to the touch pins 37, the contact limit switch 38 is fixed and an arrival limit switch 39 is fixed at a distance from the contact limit switch 38.

The function of the electronic locking and unlocking apparatus 30 will be described below. When the movable portion 33 moves according to the operation of the hydraulic cylinder 32. The touch board 25f is adhered to the powered-on electromagnet 36. In this case, the protruded touch pin 37 is pushed by the touch board 25f, to then operate the contact limit switch 38 and to thus stop the advance. Then, the touch pin 37 is returned to the original position by the elastic force of the return spring 34. Here, the locking pins 25a and 25a' are unlocked by the link 25c and the wire 25c' which are tensioned together with the touch board 25f . The arrival limit switch 39 recognizes the movable portion 33, to thus send a control signal for the next control.

Moreover, as shown in FIGS. 6 and 9, the limit switch 26 for the height recognition is installed near the axis of rotation 25a of the supporting frame 22, to thereby recognize a critical height when the assistant plate 24 rises up between the catching pieces 23. The limit switch 27 for recognizing the locked state is fixed in the periphery of the link 23, to thereby detect whether or not the link 25c is again restored and to recognize whether or not the locking pins 25a and 25a' are locked.

In the meantime, the limit switch 26 for the height recognition and the limit switch 27 for the locked state recognition unlock the locking pins 25a and 25a' and make the assistant plate 24 rotate. In this case, a collector 40 which supplies the electricity to the limit switches 26 and 27 is provided. The carriers 20 rotate along the guide rails 15. When one carrier 20 is at a standby state in the lowermost portion of the carriers, conductive bodies 44 and 44a contact each other to supply electricity. As shown in FIGS. 10 and 12, a bracket 41 is formed at a portion receiving the electricity, that is, on the supporting frame 22. Thus, a metal plate 42 like a steel plate and an insulator plate 43 like an acryl plate are fixed in turn in the form of a concave arc of a certain area. Then, two conductive bodies 44 like copper plates are fixed at a certain interval thereon to receive the electricity.

Moreover, a bracket 41a is formed in the main frame 11 which is in opposition to the conductive bodies 44, in more detail, below the electronic locking and unlocking apparatus 30, to thereby rotatably fix the pivot shaft 45. The metal plate 42a and the insulator plate 43a are fixed in sequence on the end of the pin shaft 45 in the oblique direction. Subsequently, the conductive bodies 44a whose ends have the rounded shapes are fixed at a certain interval, respectively. A bracket 46 is fixed to the pivot shaft

45, in parallel with the floor of the rotary parking apparatus. A spring 47 is fixed to the end of and perpendicularly with the bracket

46. As a result, the conductive bodies 44 and 44a contact closely each other due to the nature of rotation of the pin shaft 45 by the compressive force of the spring 47.

As described above, the palette 21 and the supporter 25 are connected by a plurality of hangers 28, in parallel with each other and at a certain altitude difference, to thereby form a carrier 20. A guide plate 28a of a plate material having a width wider than that of the hanger 28, that is, the diameter or thickness of the hanger 28 is fixed by a certain length. A roller 21c formed on the bottom of the pallet 21 of the adjacent carrier 20 is rolled and moved. The palette 21, the hanger 28, and the supporter 25 are combined to form a single carrier 20.

In the following, the turntable 50 will be illustrated with reference to FIGS. 13 to 16. In the turntable 50, a plate-shaped base 51 is fixed on the floor by means of a fixing unit like anchor bolts. The inner ring 53 of the ring shape is assembled with the inner circumference of the outer ring 52 of the ring shape having a certain height from the floor by means of bearings 52b. The upper portion of the outer ring 52 is covered with an upper plate 56. The outer ring 52 protrudes partially along the inner circumference thereof, to thereby form a gear 52a at the end thereof and assemble the bearing 52b and the inner ring 53 at the protruded edges in sequence and to thus enable the outer ring 52 and the inner ring 53 to rotate each other. A number of hydraulic cylinders 51a are installed in the base 51, to thereby enable the rod 51a' to lift the inner ring 53. The gear-box 53b' is installed in the inner ring 53 so that the final gear of the gear-box 53b' is engaged with the gear 53a of the outer ring 53. A hydraulic motor 53b is installed as a driving source of the gear 53a.

In the meantime, as shown in the enlarged view of FIG. 15, the inner ring 53 is combined with the hydraulic cylinder 51a. The inner circumference of the inner ring 53 is formed to have a C-shaped cross-section. The inner ring 53 protrudes along the upper portion of the inner circumference top of the inner ring 53, and a number of cylinder brackets 53a protruding by a certain area are formed on the lower portion of the inner circumference of the inner ring 53. A penetrated hole is formed on each cylinder bracket 53a. The outer diameter portion of the hydraulic cylinder 51a is fitted into and coupled with the penetrated hole. The rod 51a' is hung on the upper portion of the cylinder bracket 53a. The rod 51a' can lift the inner ring 53 and the turntable 50 by operation of the hydraulic cylinder 51a. Here, the inner ring 53 ascends along the hole of the cylinder bracket 53a based on the hydraulic cylinder 51a, and minimizes the movement of the cylinder bracket 53a. It is preferable that a guide like a bushing is formed in the penetrated hole of the cylinder bracket 53a, to thus make a slide facilitated.

The guide rails 51c each forming a certain space are formed on the inner circumference of the inner ring 53 in the crossways, respectively. Housings 51b in which bearings 51b¹ are assembled are fixed to the base 51 at a position spaced from the guide rails 51c, respectively. An L-shaped link 53e and a link bar 51e where a concave catching portion 53e' is formed at a certain position, are provided. A slide 53f is fitted into one end of each link 53d and fitted with each guide 53c. The two link bars 51e are fitted with and fixed to the bearings 51b' of the housing 51b and the link 53b, respectively, so as to be crossed at each catching portion 53e' . The catching portion 5Ie¹ which is positioned at the lower portion is concave downwards, and the catching portion 53e^! located above the lower catching portion 51e ' is convex upwards . The cross-linked point deviates from the center of the inner ring 53.

Moreover, the outer ring 52 is formed higher than the inner ring 53 and a rectangularly shaped frame 54 is fixed in the outside of the outer ring 52. A pin 55a is fixed to the frame 54, and a roller 55 having a V-shaped cross-section is fixed to the pin 55a. The position of the roller 55 is in accord with the guide 21b which is installed on the bottom of the pallet 21. The roller 55 only performs a rotational movement, or can move by a certain width along the pin 55a as well as perform the rotational movement. The upper portion of the outer ring 52 and the frame 54 are covered with the upper plate 56 such as an emboss plate so as to be connected with each other.

Moreover, the structures of ascending and rotating the turntable 50 will be described below. Firstly, the inner ring 53 is lifted up by operation of the hydraulic cylinder 51a, and thus the outer ring 52, the frame 54 and the upper plate 56 are altogether ascendent except for the base 51 and the housing 51b which is fixed to the base 51. Simultaneously, the link 53d and the roller 55 move along the guide 53c at the state where the link bar 53e is fixed, to thus ascend stably. The outer ring 52 and the frame 54 and the upper plate 56 which are fixed to the outer ring 52 are engaged with the gear-box 53b' and the gear 52a of the outer ring 52 connected with the gear-box 53b' and rotate together by driving of the hydraulic motor 53b.

In addition, an impact buffer 60 and a stopper 70 are additionally installed on the floor of the rotary parking apparatus. The impact buffer 60 and the stopper 70 will be described below. As shown in FIG.17, a link 62 of a certain length is rotatably fixed to a bracket 61. The central axis 63 with which a spring 63a is fitted is fixed at a certain position of the link 62, and a roller 64 is fixed to the upper portion of the end of the link 62. The impact buffer 60 is fixedly installed so that the bracket 61 and the central axis 63 are fixed on the floor and the roller 64 is fixedly installed in the lower portion of the damper board 21a of the pallet 21. The roller 64 has an H-shaped cross-section to thereby enable the damper board 21a to be easily accommodated. When the roller 64 is pressed, the link 62 moves like a lever due to the fixing of the bracket 61 and the central axis 63. Here, the spring 63a on the central axis absorbs vibrations .

Then, the stopper 70 will be described with reference to the FIG. 18. The stopper 70 includes: pillars 71 each of a certain height; rotating bodies 72 each formed of a pipe of a certain length and to the end of which an L-shaped link 72a is fixed and a bracket 72b which is fixed at a certain position of the L-shaped link 72a; a rotatable damper (73) which can rotate with the roller in which the rotating bodies 72 each playing a role of a fitting link are fitted between the two pillars 71 which are fixed at a certain interval on the floor of the rear side of the outer body 11 and the damper 73 which is installed between the ends of the respective links 72a; a fixing pin 74 which is installed at a position perpendicular with the center between the two pillars 71; and a spring 75 which is connected between the fixing pin 74 and the respective brackets 72b. The rotary parking apparatus having the above-described configuration according to the present invention will be described below with reference to FIGS. 1 to 4. The carriers 20 are respectively assembled with each connection plate 14 of the outer body part 11. The turntable 50, the impact buffer 60 and the stopper 70 are installed on the floor of the rotary parking apparatus. Each guide 21b of the carriers 20 is in accord with each roller 55 of the turntable 50 in the vertical direction of the rotary parking apparatus. Each damper board 21a of the carriers 20 is in accord with each roller 64 of the impact buffer 60 in the vertical direction of the rotary parking apparatus. The damper 73 of the stopper 70 is positioned at a place where the front tires 2 of a vehicle 1 are positioned when the vehicle 1 is parked.

For example, the turntable 50 and the buffer 60 can be immediately installed on the flat land. However, as shown in FIGS. 2 and 3, the flat land can be dug by a certain depth and a certain area. Then, the turntable 50 can be installed in the inside of the dug land, and the impact buffer 60 is installed at the lateral and inner sides of the turntable 50. Accordingly, a standby carrier 20 can be level with the surface of the land. Thus, a stepboard (not shown) needs not be installed. It is preferable that a waterway should be necessarily installed to prevent rainwater from staying in the case that the surface of the land has been dug so that the turntable 50 can be installed in the inside of the dug land.

Α method of using the rotary parking apparatus of the above-described structure according to the present invention will be described with reference to the state diagram of FIG. 19 and the flowchart of FIG.20. When a vehicle 1 advances into a standby empty carrier 20, tires 2 contact the stoppers 70 of FIG. 3, so that the vehicle 1 is parked at a proper position. Then, the electronic locking and unlocking apparatus 30 is operated to unlock the locking pins 25a and 25a' . The turntable 50 rises up due to the action of the hydraulic cylinder 51a, and the roller 55 of the turntable 50 is fitted into the guide 21b of the lower portion of the pallet 21, to thus hold the position of the roller 55 and prevent the roller 55 from freely moving. Simultaneously, the limit switch 26 for the height recognition recognizes the height of the carrier 20 to make the hydraulic cylinder 51a stopped, and the outer ring 52 rotate by the operation of the hydraulic motor 53b. Thus, the palette 20, the hanger 28, and the assistant plate 24 as well as the fixed frame 54 and the upper plate 56, are rotated around the axis of rotation 25a, to thereby change the direction of the vehicle 1.

Therefore, after the vehicle 1 has been rotated by 180 degrees, the turntable 50 descends again by the operation of the hydraulic cylinder 51a, and the electronic locking and unlocking apparatus 30 is unlocked. Accordingly, the locking pins 25a and 25a ' are again locked, to then maintain the locked state. The carrier 20 in which the vehicle is loaded ascends along the guide rail 15 by the operation of the drive motor 12. Subsequently, an empty carrier 20 descends and is at a standby state. Here, the damper 73 contacting the tires 2 while the carrier 20 rises up gets twisted a little. However, an impact is absorbed into the rotating bodies 72 and the link 72a. Although the damper 73 gets twisted, it is again restored by the spring 75. The roller 21c of the lower portion of the carrier 20 rolls along the guide plate 28a attached to the adjacent hanger 28 at an arc section where the carrier 20 moves, to thereby prevent the carriers 20 from colliding with each other and minimize rubbing and scratching.

For example, the rollers 21c, 22b, 55, and 64 and the damper 73 are a rotating object which is formed of a substantially cylindrical form, respectively, and plays a role of converting a sliding friction into a rolling friction to reduce resistance of movements. In addition, the rollers are made of synthetic resin or the rubber materials with an excellent durability. Accordingly, the rotary parking apparatus rotates with the scratches minimized and the vibrations absorbed.

The present invention provides the following effects. The present invention provides a rotary parking apparatus having a turntable which is installed in the lower portion thereof, and rises by a plurality of hydraulic cylinders in which a plurality of carriers are circulated along an elliptic guide rail and rotated by 180 degrees, to thereby park a number of vehicles in the parking apparatus and take the same out therefrom conveniently, and save an installation space which is needed to install the rotary parking apparatus . The present invention provides a rotary parking apparatus which includes: a damper which moves by a linkage in the periphery of the turntable and a stopper formed of a spring for restoring the position to thus make a parking location identified when parking; a number of rollers attached below a respective carrier to form an impact buffer functioning as a leverage, in such a manner that a damper plate below the carrier contacts the rollers to remove vibration; and a guide plate of a certain area which is fixed to a hanger of the carrier and the number of the rollers which are fixed to the lower portion of the carrier, in such a manner that when the carrier moves to another place, the rollers move along a guide plate of the hanger between the adjacent rollers to thus prevent any collision therebetween.
