Description

[Technical field]

[0001] The present invention relates to a two-level vehicle parking facility, and in particular to a two-level vehicle parking facility with which vehicles can be parked in two levels, upper and lower, in a narrow space, and in which when parking a vehicle in the upper position, the frame body is transported forward and a support plate is lowered to make it easier for even a driver who is not accustomed to parking to park, so that the vehicle can be parked in the direction of travel of the vehicle; when the support plate is raised and lowered vertically using first and second lifting chains, the height displacement of the support plate can be variably adjusted by a compensation device, so that the overall volume of the frame body can be reduced to a compact size; and when the frame body moves forward and backward using a traveling means, the linear movement of the frame body is guided by guide protrusions and traveling rollers to prevent it from straying from the direction of movement. [Background technology]

[0002] In general, as income levels rise, the number of passenger cars increases exponentially, and the problem of parking cars has become a major concern, especially in densely populated urban areas. Therefore, in order to solve this problem, parking devices that can make the most of small spaces are required.

[0003] As solutions to these parking problems, a multi-level circular parking system, a multi-level parking system, a two-level parking system, and the like are known.

[0004] However, in the case of multi-level parking systems and multi-level parking systems in parking buildings, although they can maximize the use of space, they are expensive to install and maintain, and take a long time to enter and leave the parking lot, which is inconvenient. For these reasons, the installation of these types of parking systems is avoided, and users are reluctant to use them.

[0005] For this reason, two-level parking systems have been proposed and implemented that can efficiently utilize small spaces while, unlike multi-level parking systems, allowing vehicles to easily enter and exit each parking level.

[0006] Such a conventional two-level or three-level parking device is disclosed in Korean Patent Publication No. 91-17040. The parking device is a two-level parking device, and a pallet that can be raised and lowered by a driving means is installed inside a frame material including a support pillar, and after a vehicle is parked on the pallet, the pallet with the vehicle mounted thereon is raised by the driving means, and another vehicle is parked under the raised pallet. However, this requires a large amount of power to raise and lower the pallet and the vehicle mounted on the pallet, which increases management costs.

[0007] Conventional two-level or multi-level parking systems mainly consist of simple lifting devices.

[0008] As a conventional prior art related to a conventional two-level parking device, as disclosed in Korean Patent Publication No. 1996-2342 "Non-powered Two-level Parking Device" (Registration date: February 16, 1996), a lower frame is arranged on the floor, front and rear vertical pillars are arranged vertically to form a parking space in front of the lower frame, front and rear vertical frames are arranged vertically behind the rear vertical pillars, a horizontal pillar connecting the upper ends of the front and rear vertical pillars from front to rear, plate members connecting the upper ends of the front and rear vertical frames from front to rear, and a cross bar connecting the upper ends of the plate members from side to side is provided inside the framework structure, and a mounting platform and lifting means for raising and lowering the mounting platform are provided. The two-level parking device mounted on a vehicle is configured as follows: the mounting platform is composed of a mounting platform frame and an inclined plate that is elastically mounted on the upper part of the mounting platform frame by a spring so as to rotate around a hinge; the lifting means is composed of a lower plate weight that rises via a first traction means provided on both sides when the inclined plate descends, a reference plate weight for raising and lowering the mounting platform via second and third traction means provided on both sides, respectively, an upper plate weight that is supported and raised and lowered via a fourth traction means, and a plurality of intermediate plate weights provided between the reference plate weight and the upper plate weight; and the mounting platform is configured to rise and lower via the traction means by connecting and disconnecting these plate weights.

[0009] In the prior art described above, an inclined plate rotates around a hinge at the top of the mounting frame to allow a vehicle to enter the parking lot. However, in this case, the inclined plate interferes with the vehicle on the lower level, so there is an inconvenience that the vehicle can only enter the parking lot after the vehicle parked on the lower level has left the parking lot.

[0010] In addition, conventional two-tier parking systems not only had the inconvenience of requiring a vehicle parked on the upper level to be removed after a vehicle parked on the lower level has been removed, but also had the troublesome problem of requiring a vehicle parked on the lower level to be moved when parking on the upper level.

[0011] To solve this problem, there is a so-called puzzle-type parking machine in which the lower plate is moved left and right, an empty space is created on the lower level, and the upper plate is lowered. However, this method also has the disadvantage that it is inconvenient to have to move the vehicle on the lower level, and additional space is required to move the vehicle parked on the lower level.

[0012] Another prior art of a two-level parking device to overcome this problem is disclosed in Korean Patent Publication No. 10-1288702 "Multi-level Parking System" (registration date: July 16, 2013), which includes a double rail that is parallel to the parking direction on the floor of the parking system and is located on the left or right side of the parking position; a control box located on the double rail, the control box being located between the double rail and the control box so as to be able to move along the double rail, and having two upper rollers and a lower roller respectively installed on the upper and lower parts of the double rail; a pillar that is vertically erected on top of the control box and connected to the control box, the pillar being rotatable independently of the control box around the vertical axis of the pillar as a rotation axis; a chain located within the pillar, configured to be wound in the vertical direction of the pillar; a plate on which a vehicle is parked and which guides the vehicle up and down; and a plate holder that supports the plate and is fastened to the chain, the plate holder moving up and down as the chain is wound in the vertical direction.

[0013] The control box further includes a clamping member that is clamped between the rails of the double rail and between the outer surface of the double rail and the side surface of the ground.

[0014] In this case, the plate on which the vehicle is placed rotates around the vertical axis of the pillar, which has the advantage of avoiding interference with the vehicle positioned on the lower level. However, because the plate is supported on the pillar in a cantilever-like manner, the load of the plate on which the vehicle is placed is concentrated at the rotating connection part of the pillar, which may cause warping deformation or cracks.

[0015] This can reduce the durability of the parts and, in severe cases, can lead to the vehicle crashing and sustaining damage or causing a safety hazard.

[0016] In addition, while conventional two-level parking systems are applicable to tall buildings and underground parking lots, they have the disadvantage that they cannot be applied to private homes where the space in the width direction is limited.

[0017] In particular, conventional two-level and multi-level parking systems require floor construction work such as pouring concrete in order to erect the frame on the ground or install a support structure to support the frame, which not only takes a long time for construction work but also has the disadvantage that the floor may be damaged, resulting in economic and time losses, and in some cases, restoration costs may be incurred if the system is restored to its original state.

[0018] Meanwhile, conventional prior art related to a lifting device that lifts the above-mentioned vehicle to the two-stage position is disclosed in Korean Patent No. 10-2074670, "Vertical Lift Mechanism" (registration date: February 3, 2020), which includes a frame, a drive unit installed on the frame, a linear actuator that moves linearly with power provided by the drive unit, a scissor link whose one end is connected to the linear actuator and expands and contracts vertically, a lifting module connected to the other end of the scissor link and rises and lowers in accordance with the expansion and contraction of the scissor link, and a support plate connected to the lifting module and raises and lowers an object as the lifting module rises and lowers.

[0019] Conventional lifting devices are designed to lift and lower a lifting module using an extendable scissor link. However, this not only takes up a lot of installation space due to the volume of the scissor link, but also requires that the lifting module be raised and lowered with the same lifting force and to the same height on both sides when the scissor links on both sides of the frame extend and retract. If synchronization is not performed properly, there is a risk of the vehicle placed on the lifting module falling.

[0020] Conventional parking equipment uses a scissor link system to raise and lower a lifting module relative to a frame, but this system may not be able to lift and lower a heavy vehicle smoothly, and there is a risk of the vehicle falling during the lifting operation.

[0021] Therefore, in order to make up for the shortcomings of the conventional parking equipment, it is necessary to make the frame move forward and backward along the rails in a straight line, and a parking equipment technology is required that can ensure safety by smoothly operating the lifting means that raises and lowers the vehicle to the upper and lower positions, and by ensuring that the lowering operation of the support plate on which the vehicle is placed is performed only when the support plate rotates at an angle of 90 degrees. The following present invention describes the technology related to this. [Prior art documents] [Patent documents]

[0058] The tension bracket 172 further includes a handle 174 on the rear side for easy gripping by an operator.

[0059] The guide means changes the direction of the first and second lift chains 332, 334 so as to connect the other ends of the first and second lift chains 332, 334 to the second fixed member 350 side, and the guide means is configured as follows, as shown in Figs. 2, 3, 7 and 8: a first guide sprocket 710 that guides the first lift chain 332 transmitted from the first and second lift sprockets 322, 324 of the lift shaft 320 to the second fixed member 350 side and guides the movement of the first lift chain 332 when the connecting shaft 225 moves up and down; a second guide sprocket 720 that changes the direction of the second lift chain 334 transmitted from the first and second lift sprockets 322, 324 of the lift shaft 320 downward; The frame includes a third guide sprocket 730 disposed within the first and second lower frames 21 and 22 and configured to redirect the second lifting chain 334 descending from the second guide sprocket 720 forward; a fourth guide sprocket 740 disposed on the first and second lower frames 21 and 22 spaced forward from the third guide sprocket 730 and configured to redirect the second lifting chain 334 upward; and a fifth guide sprocket 750 disposed on the upper parts of the third and fourth vertical frames 25 and 26 and configured to guide the second lifting chain 334 redirected upward by the fourth guide sprocket 740 toward the second fixed member 350 provided on the upper parts of the third and fourth vertical frames 25 and 26.

[0060] The compensation device 600 includes a first redirecting sprocket 610 that redirects the direction of the first and second lifting chains 332 and 334 that are directed upward from the lifting block 620 downward, and second and third redirecting sprockets on both sides of the first and second lifting chains 332 and 334, one end of which is fixed to the first fixing member 340, so that the first and second lifting chains 332 and 334 are vertically arranged in a zigzag shape with respect to the first redirecting sprocket 610. 630、640 and a lift block 620 that moves up and down according to the rotation direction of the lift shaft 320, and a third changeover sprocket that connects the first and second lift chains 332 and 334 to the third changeover sprocket. 640 and a guide sprocket 650 that guides the lift shaft 320 from the first lift sprocket 322, 324 side.

[0061] The compensation device 600 is connected to the first and second lower frames 21 and 22 in the vertical direction so as to penetrate the lift block 620. First and second vertical frames 23, 24 and a vertical guide rod 660 for guiding the lifting block 620 so as to suppress free movement of the lifting block 620 when the lifting block 620 is raised or lowered in the vertical direction.

[0062] In addition, the compensation device 600 is connected so that one ends of the first and second lifting chains 332, 334 are fixed to the first fixed member 340, and the other ends of the first and second lifting chains 332, 334 are fixed to the second fixed member 350 on the lifting rails 800 of the first, second, third and fourth vertical frames 23, 24, 25 and 26, and compensates for the height displacement generated when the lifting block 620 is lifted up and down to compensate for the displacement of the first and second lifting chains 332, 334 due to the change in height of the connecting shaft 225, which moves up and down according to the rotation direction of the lifting shaft 320.

[0063] That is, in the compensation device 600, when the connecting shaft 225 provided at the edge portion of the lower plate 220 is at the upper side, the lift block 620 is located at the lower position. However, when the connecting shaft 225 is moved downward to move the receiving plate 200 downward, the lift motor 310 is driven in the reverse direction to rotate the lift shaft 320 in the reverse direction, so that one end and the other end of the first and second lift chains 332 and 334 are fixed to the first and second fixing members 332 and 334 as shown in FIG. 2 and FIG. 7. 340,350 As the other ends of the first and second lift chains 332, 334 are unwound by the first and second lift sprockets 322, 324 of the lift shaft 320, the connecting shaft 225 placed on the upper side of the other ends of the first and second lift chains 332, 334 slowly moves down to assist the lowering of the connecting shaft 225. As the other ends of the first and second lift chains 332, 334 are unwound, the second and third switching sprockets 620, 630 of the lift block 620 are pulled toward the first fixing member 340 to which one ends of the first and second lift chains 332, 334 are fixed, and rise upward while being suspended by the first and second lift chains 332, 334.

[0064] On the other hand, when it is desired to raise the receiving plate 200, the lifting motor 310 is driven in the forward direction to rotate the lifting shaft 320 in the forward direction. As a result, as shown in Figures 3 and 7, one ends of the first and second lifting chains 332, 334 are moved in a direction in which they are pulled toward the first and second lifting sprockets 322, 324 by the first and second lifting sprockets 322, 324 of the lifting shaft 320, and one ends of the first and second lifting chains 332, 334 are unwound in a direction in which the lifting block 620 is lowered. At the same time, the lifting shaft 320 is lowered while placed on the other end side of the first and second lifting chains 332, 334, thereby lifting the receiving plate 200 upward.

[0065] As shown in FIGS. 9 and 10, the rotating means 400 has a structure in which the upper plate 210 rotates with respect to the lower plate 220 only after the frame body 20 has been moved forward by the traveling means 100.

[0066] The rotating means 400 is disposed on the upper surface of the lower plate 220, and is driven to rotate when an external power source is applied. The rotating means 400 includes a rotating motor 410 having a rotating gear 415 that rotates when driven to rotate, and being driven to rotate in forward and reverse directions, a first rotating shaft 420 that is connected to the rotating gear 415 of the rotating motor 410 at its upper portion and has a first rotating sprocket 422 connected to its lower portion, and stands vertically on the lower plate 220, and a rotating chain 440 that is connected to the first rotating shaft 420 at a position spaced apart from the first rotating shaft 420. In the embodiment, the upper plate 220 includes a second rotating sprocket 432 connected to the first rotating sprocket 422, a second rotating shaft 430 having a rotating member 435 at its upper part for interlocking and rotating a rotating plate 450 connected to the upper plate 210, a rotating plate 450 having a ring gear 455 connected to the lower part of the upper plate 210 and meshing with the rotating member 435, and a first rolling roller 460 spaced apart from each other and installed on the upper side of the lower plate 220 to rotatably support the rotating plate 450.

[0067] As shown in Figures 9 and 10, the rotation means 400 further includes an annular support plate 470 disposed outside the first rolling roller 460 and coupled to the lower part of the upper plate 210, and a second rolling roller 480 provided on the lower plate 220 and supporting the rotation of the support plate 470 from below.

[0068] The first rotating shaft 420 includes an interlocking gear 425 interlocked with the rotating gear 415 of the rotating motor 410 at an upper portion thereof, and the rotating gear 415 and the interlocking gear 425 may be bevel gears.

[0069] As shown in FIG. 10 , the rotating member 435 has a plurality of rotating rods around its outer periphery, which are spaced apart at intervals corresponding to the gear pitch of the ring gear 455 of the rotating plate 450. The plurality of rotating rods are engaged with the ring gear 455, and thus rotate the rotating plate 450 while being rotary rotated by the rotational force of the second rotating shaft 430.

[0070] In addition, as shown in FIG. 9, the rotation means 400 further includes a brake roller 495 rotatably disposed on the upper side of the lower plate 220 with a support shaft (not shown), which transmits a braking force to the upper plate 210 side when the rotation means 400 comes into contact with the lower surface of the upper plate 210 and rotates in conjunction with the upper plate 210 to transmit a braking force thereto, and a disk brake 490 axially coupled to the support shaft, which transmits a braking force to the brake roller 495 side via the support shaft when a control signal is applied from a control unit (not shown) in accordance with the rotation angle of the upper plate 210.

[0071] As shown in Figures 10 and 12, the rotation means 400 is disposed in the space between the upper plate 210 and the lower plate 220, and when an external power source is applied to the rotation motor 410, the rotation motor 410 is rotated in a forward or reverse direction. When the rotation motor 410 is rotated in the forward direction, the upper plate 210 and the lower plate 220 rotate in a forward direction so as to intersect at an angle of 90° so as not to interfere with each other when they move up and down, or the upper plate 210 rotates in a reverse direction at an angle of 0° to return to its original position.

[0072] On the contrary, when the rotation motor 410 is driven in the reverse direction, the upper plate 210 returns to the rotation angle of 0° (360°) where both ends of the upper plate 210 interfere with the lower plate 220.

[0073] When the rotation motor 410 is driven in the forward direction, the rotation means 400 rotates the first rotating shaft 420 by engaging the rotating gear 415 of the motor shaft with the interlocking gear 425 of the first rotating shaft 420 in a bevel gear type, and transmits a rotational force to the second rotating sprocket 432 side via the first rotating sprocket 422 and the rotating chain 440 provided at the lower part of the first rotating shaft 420 to rotate the second rotating shaft 430, and rotates the rotating member 435 provided at the upper part of the second rotating shaft 430 to interlock and rotate the rotating plate 450 and the upper plate 210 via the ring gear 455 as described above.

[0074] At this time, in the rotating means 400, the first rolling rollers 460 contact the underside of the rotating plate 450 and support the underside of the rotating plate 450 while rolling, so that the rotating operation can be performed smoothly when the rotating plate 450 rotates, thereby assisting the rotation of the rotating plate 450.

[0075] The rotating means 400 further includes a rotation detecting sensor (not shown) for detecting a rotation angle of 90° or 0° of the upper plate 210 and outputting the detected angle information to a control unit.

[0076] In addition, in order to support the rotation of the rotating plate 450, the rotation means 400 has a plurality of second rolling rollers 480 that support the underside of the support plate 470 connected to the upper plate 210, and rolls in conjunction with the underside of the support plate 470 when the upper plate 210 and the support plate 470 rotate, thereby helping to ensure that the rotation of the support plate 470 connected to the upper plate 210 is performed smoothly.

[0077] Meanwhile, the rotation means 400 operates the disc brake 490 to stop the rotation of the upper plate 210 after the upper plate 210 is positioned at a fixed position (0° or 90°), and transmits a braking friction force to the upper plate 210 through the brake roller 495 to limit the rotation of the upper plate 210, thereby preventing malfunction of the product.

[0078] The above 1st, 2nd, 3rd, 4th vertical frames As shown in FIG. 1, 23, 24, 25, and 26 are each formed with a lifting rail 800 on the inner side facing each other to guide the lifting and lowering movement of the connecting shaft 225 respectively provided at the edge portion of the lower plate 220 of the receiving plate 200, and the lifting rail 800 is formed with flange portions 810 on both the left and right sides of the inlet side facing each other to prevent the inclination of each connecting shaft 225 when the first and second lifting chains 332 and 334 are broken.

[0079] The receiving plate 200 further includes a stopper means 500 which is rotatably mounted on a hinge shaft on both the left and right sides of the upper plate 210, and which has a stopper plate 510 for guiding the entry of a vehicle entering the upper side of the upper plate 210 when the receiving plate 200 is lowered, and for preventing a vehicle placed on the upper plate 210 from falling.

[0080] 5 and 6, the stopper means 500 includes a stopper bracket 530, one end of which is rotatably connected to a first rotating shaft 520 disposed under the upper plate 210, and the other end of which contacts the first and second lower frames 21 and 22 when the upper plate 210 moves downward, and which rotates by contacting the first and second lower frames 21 and 22, a spring member 540 interposed between the stopper bracket 530 and the upper plate 210 and elastically supporting the other end of the stopper bracket 530 in a downward direction, a first stopper sprocket 525 coupled to the first rotating shaft 520 and rotates in conjunction with the first rotating shaft 520, and a second stopper sprocket 565 connected to the connecting chain 550 in conjunction with the rotation of the first stopper sprocket 525. are combined The stopper plate 510 includes a second rotating shaft 560 and a connecting member 570 that is connected to the second rotating shaft 560 so as to move in conjunction with the second rotating shaft 560 and is linked to support the rotation of the stopper plate 510.

[0081] The stopper bracket 530 has the other end formed in a cup shape with an upward opening so that the lower end of the spring member 540 can be accommodated therein, and has a structure in which the lower part of the other end contacts the upper surfaces of the first and second lower frames 21 and 22 when the receiving plate 200 descends, thereby rotating the first rotating shaft 520 and the first stopper sprocket 525.

[0082] The first and second rotating shafts 520 and 560 are structured to rotate in conjunction with each other through the first and second stopper sprockets 525 and 565 and a connecting chain 550, and the second rotating shaft 560 is connected to the link member 570 to rotate the stopper plate 510.

[0083] The link member 570 has the function of transmitting the rotational motion of the second rotating shaft 560 to the stopper plate 510 at an expanded rotation angle, and for that purpose, is composed of a first link member 572 connected to the second rotating shaft 560, and a second link member 574 rotatably pin-connected to the end of the first link member 572 and connected to interlock with the stopper plate 510.

[0084] The connecting chain 550 is connected in a track shape to rotate the first and second stopper sprockets 525, 565 in an interlocking manner.

[0085] In the present invention, with the receiving plate 200 positioned at the top of the first, second, third and fourth vertical frames 23, 24, 25 and 26, the frame body 20 is moved forward along the rail member 10 by the traveling means 100, and then the upper plate 210 of the receiving plate 200 is rotated at an angle of 90° relative to the lower plate 220 by the rotating means 400, and the receiving plate 200 is lowered by the lifting means 300.

[0086] When the receiving plate 200 is lowered, the end of the stopper plate 510 is rotated toward the ground by the stopper means 500 so that the vehicle can be guided to be placed on the upper side of the upper plate 210 of the receiving plate 200.

[0087] Therefore, when parking in the upper two-tier position, the driver can lower the support plate 200 in the same direction as the vehicle's travel to a position close to the road surface, which has the advantage that even drivers who are not accustomed to parking can park easily, as the vehicle can run in the same direction as the vehicle's travel to the upper side of the support plate 200, rather than using the ``T'' shaped method which is difficult to use when parking in two tiers.

[0088] At this time, after the upper plate 210 of the receiving plate 200 is raised upward, the vehicle 1st, 2nd, 3rd, 4th vertical frames 23, 24, 25, 26 It rises to the upper two-stage position.

[0089] After that, after the vehicle is placed on the upper side of the upper plate 210, the receiving plate 200 is raised upward again by the lifting means 300, and the upper plate 210 on which the vehicle is placed is rotated by the rotation means 400 so that it has a rotation angle of 0°, which is its original position, relative to the lower plate 220.

[0090] Next, by using the travelling means 100 to move the frame body 20 backward along the rail member 10, a vehicle can be parked in a single tier position below the receiving plate 200, making it possible to park vehicles in two tiers, one above the other, thereby improving the parking efficiency of vehicles in a narrow space.

[0091] As described above, in the traveling means 100, when the traveling motor 110 is driven in the forward direction, the traveling shaft 120 is driven to rotate in the forward direction, and the first and second traveling chains 132, 134 rotate in the forward direction due to the forward rotation of the traveling shaft 120, and the plurality of traveling rollers 140 roll on the rail member 10 due to the forward driving of the first and second traveling chains 132, 134, thereby moving the frame body 20 forward.

[0092] At this time, the first and second running chains 132 and 134 maintain an appropriate tension during orbital rotation by a plurality of auxiliary sprockets 150 and tensioners 170.

[0093] In the traveling means 100, when the traveling motor 110 is driven in the reverse direction, the traveling shaft 120 is driven to rotate in the reverse direction, and the first and second traveling chains 132 and 134 rotate in the opposite direction due to the reverse rotation of the traveling shaft 120. The first and second traveling chains 132 and 134 are driven in the opposite direction, and a plurality of traveling rollers 140 roll on the rail member 10 to move the frame body 20 backward.

[0094] When the lifting motor 310 is driven in the forward direction, the lifting means 300 rotates the lifting shaft 320 in the forward direction, and when the lifting shaft 320 is driven in the forward direction, the first and second lifting chains 332, 334 are wound around the first and second lifting chains 332, 334 so that one end of the first and second lifting chains 332, 334 connected to the first fixed member 340 is unwound to lower the lifting block 620, thereby acting as a pulling force on the other end of the first and second lifting chains 332, 334 connected to the second fixed member 350, thereby lifting the connecting shaft 225 upward and raising the receiving plate 200.

[0095] Meanwhile, when the lifting motor 310 is driven in the reverse direction, the lifting means 300 rotates and drives the lifting shaft 320 in the reverse direction, and when the lifting shaft 320 is driven in the reverse direction, the other ends of the first and second lifting chains 332 and 334 connected to the second fixed member 350 are unwound to lower the connecting shaft 225 downward.

[0096] At this time, when the lift motor 310 is driven in the forward and reverse directions, the lift block 620 of the compensation device 600 moves up and down to compensate for the change in height displacement of each part of the first and second lift chains 332 and 334.

[0097] When the rotation motor 410 is driven in one direction, the rotation means 400 rotates the first rotation shaft 420 in the forward direction by the rotation gear 415 and the interlocking gear 425 rotating in conjunction with each other, rotates the second rotation shaft 430 in conjunction with each other via the second rotation sprocket 432 connected to the first rotation sprocket 422 of the first rotation shaft 420 by a rotation chain 440, rotates the rotation plate 450 formed with a ring gear 455 using the rotation member 435 of the second rotation shaft 430, and rotates the upper plate 210 connected to the rotation plate 450 at a rotation angle of 90° relative to the lower plate 220.

[0098] At this time, the rotating means 400 can perform a brake function by using a rotation detection sensor to stop the rotation of the rotating motor 410 after the upper plate 210 has rotated at a rotation angle of 90°, and transmitting the braking force of the disc brake 490 to the brake roller 495 in contact with the upper plate 210 to suppress the movement of the upper plate 210.

[0099] In addition, when the rotation motor 410 is driven in the other direction, the rotating gear 415 and the interlocking gear 425 rotate in an interlocking manner to rotate the first rotating shaft 420 in the reverse direction, the second rotating shaft 430 is rotated in an interlocking manner via the second rotating sprocket 432 connected to the first rotating sprocket 422 of the first rotating shaft 420 by a rotating chain 440, the rotating member 435 of the second rotating shaft 430 is used to rotate the rotating plate 450 on which a ring gear 455 is formed, and the upper plate 210 connected to the rotating plate 450 is rotated in the reverse direction relative to the lower plate 220 to return to the rotation angle of 0°.

[0100] The rotating means 400 includes a rotating plate 450, first and second rolling rollers 460, 480 and a support plate 470 to assist the rotation of the upper plate 210 when the upper plate 210 rotates, and thus has the advantage that the rotation of the upper plate 210 can be smoothly performed and the lifting means 300 operates only when the upper plate 210 rotates at a rotation angle of 90° so that the vehicle can be mounted in the longitudinal direction of the frame body 20.

[0101] The present invention has the advantage that the frame body 20 can be made to run smoothly while maintaining straightness using the guide protrusions 15 and multiple running rollers 140 in the process of running in the forward and backward directions on the rail member 10 by using the running shaft 110 of the running means 100 and the first and second running chains 132, 134 to rotate on the left and right sides of the first and second vertical frames 23, 24, and that the tension of the first and second running chains 132, 134 can be maintained using multiple auxiliary sprockets 150 and tensioners 170.

[0102] In addition, the present invention has the advantage that the connecting shafts 225 respectively installed at the edge portions of the lower plate 220 of the receiving plate 200 can be smoothly raised and lowered up and down within the lifting rail 800 using the first and second lifting chains 332, 334 of the lifting means 300, and that the height changes at different portions of the first and second lifting chains 332, 334 due to the height displacement of the connecting shafts 225 can be compensated for using the compensation device 600, thereby reducing the overall volume of the frame body 20.

[0103] In the present invention, the upper plate 210 of the receiving plate 200 can be smoothly rotated in the process of rotating and returning the upper plate 210 at a rotation angle of 90° relative to the lower plate 220 using the rotation motor 410 of the rotation means 400, the first and second rotation shafts 420, 430, and the rotation member 435, and the lifting means 300 is operated only when the upper plate 210 rotates at a rotation angle of 90° so that the vehicle is mounted in the longitudinal direction of the frame body 20, thereby enabling a safe parking operation.

[0104] Thus, although the detailed description of the present invention has been given of specific embodiments, it goes without saying that various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined not only by the claims to be described below, but also by equivalents to the claims.
