Description

Technical Field

[0001] The present invention relates to a three-dimensional garage, in particular to a three-dimensional vehicle storage device for an underground parking lot and a method for storing and retrieving vehicles. Background Art

[0002] As an important facility to relieve the urban parking pressure, underground parking lots have been widely used in cities in recent years. However, with the continuous increase in the number of automobiles in large and medium-sized cities, the speed of planning and construction of parking spaces far lags behind the growth rate of the number of automobiles. Therefore, the problem of difficult parking in large and medium-sized cities is still intensifying year by year. To alleviate the problem of difficult parking, those skilled in the art have designed a three-dimensional vehicle storage device that can store vehicles on two floors in some underground parking lots where the floor height meets the requirements, so as to increase the number of parking spaces in the underground parking lot. However, in use, many problems have also emerged in such vehicle storage devices. The primary problem is that such vehicle storage devices require the driver to drive the vehicle into the parking space by himself / herself. Since such three-dimensional parking spaces need to be provided with brackets and lifting devices, the width and length of the parking spaces are relatively small. Some drivers have difficulty accurately parking the vehicle into the parking space. Even if the vehicle is successfully parked in the parking space, the space for the driver and passengers to open and close the doors on both sides of the vehicle is very limited. Therefore, after such vehicle storage devices are put into use, problems such as the vehicle being scratched, bumped, and the wheels being squeezed often occur.

[0003] To avoid the above problems, most of the management regulations for mechanical multi-storey parking garages in various places require the vehicle storage management personnel to guide the driver to store and retrieve the vehicle beside the parking space. However, in the actual operation of such garages, due to reasons related to labor costs, the operating unit does not have the condition to equip each parking space with a full-time management personnel. It can only provide guidance for the driver in the way that a few management personnel patrol among multiple parking spaces and immediately step forward to help when they find that a vehicle is about to enter or leave the parking space. However, for relatively large underground parking lots, such a patrol method still requires multiple management personnel to be on duty for patrol at the same time, the labor cost is still relatively high, the labor intensity of the management personnel is also relatively large, and it is difficult to ensure that the management personnel can guide each vehicle in a timely manner during the peak hours of vehicle storage and retrieval. Therefore, the phenomenon of vehicle damage still often occurs during the operation of the garage. Summary of the Invention

[0004] The object of the present invention is to provide a three-dimensional vehicle storage device for an underground parking lot and a method for accessing vehicles. It can move the vehicle carrier plate in the three-dimensional vehicle storage device arranged in the underground parking lot to a shared vehicle handover area through a servo bracket, so that the access of vehicles is completed in the vehicle handover area. The vehicle access positions in the vehicle handover area are fixed positions, and there are no brackets and lifting devices on both sides to hinder. It is more convenient for the driver and passengers to park and get on and off the vehicle. One or two managers are arranged in the vehicle handover area to guide the driver to park the vehicle. The managers do not need to conduct inspections, which greatly reduces the labor cost of the parking lot operation unit and the labor intensity of the managers, and can ensure that the storage of each vehicle is completed under the guidance of the managers, which is conducive to reducing the occurrence frequency of vehicle damage phenomena.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: The three-dimensional vehicle storage device for an underground parking lot of the present invention includes at least one set of vehicle storage frames, and each set of vehicle storage frames is arranged side by side. N upper vehicle storage positions are arranged side by side on the upper part of each set of vehicle storage frames, where N is greater than or equal to 2. Each upper vehicle storage position is provided with a lifting bracket, and a corresponding lower vehicle storage position is arranged below each upper vehicle storage position. Each lifting bracket can descend into the corresponding lower vehicle storage position below. A total of N - 1 transverse moving brackets are arranged in the lower vehicle storage positions. Each transverse moving bracket is provided with a transverse moving driving device, and each transverse moving bracket can move to an adjacent lower vehicle storage position under the drive of the transverse moving driving device. A servo bracket is arranged on one side of the vehicle storage frame, and at least one access vehicle storage position is arranged on the servo bracket. The servo bracket can move along the width direction of each upper vehicle storage position and the lower vehicle storage position. When the servo bracket moves, the access vehicle storage position on the servo bracket can be docked with any one of the transverse moving brackets and the lifting bracket that has descended into the lower vehicle storage position. A vehicle carrier plate is placed on each of the lifting brackets and the transverse moving brackets, and rollers are provided on the vehicle carrier plate. When the access vehicle storage position on the servo bracket is docked with any one of the transverse moving brackets and the lifting bracket that has descended into the lower vehicle storage position, the vehicle carrier plate can move between the servo bracket and the transverse moving bracket or the lifting bracket. A moving frame is installed in each access vehicle storage position of the servo bracket, and the moving frame can move between the end of the access vehicle storage position away from the vehicle storage frame and the end of the access vehicle storage position close to the vehicle storage frame. A connecting member that can be connected and separated is provided between the moving frame and the vehicle carrier plate. At least 2 sets of fixed pulleys are provided on the vehicle storage frames on both sides of each upper vehicle storage position. A winding drum is arranged on the vehicle storage frame at one end of each upper vehicle storage position. At least 2 sets of lifting steel wires are provided on both sides of each lifting bracket. Each lifting steel wire bypasses a fixed pulley at its corresponding position and is connected to the winding drum. When the winding drum rotates, it can synchronously wind and release each lifting steel wire. Anti-falling devices are arranged on the vehicle storage frames on both sides of each upper vehicle storage position. When the lifting bracket rises to the upper vehicle storage position, the anti-falling device can lock the height of the lifting bracket to prevent the lifting bracket from falling. A transverse guide rail is arranged along the width direction of each upper vehicle storage position at the top of the vehicle storage frame. A transverse moving trolley is installed on the transverse guide rail, and walking wheels are arranged on the transverse moving trolley. The walking wheels are connected to the output shaft of a walking motor, and the walking motor can drive the transverse moving trolley to move along the transverse guide rail through the walking wheels. A lifting driving motor is arranged on the transverse moving trolley, and the output shaft of the lifting driving motor is connected to the middle of a rotating lever. The lifting driving motor can drive the rotating lever to rotate. Two convex columns are arranged on one end face of each winding drum of each upper vehicle storage position. When the transverse moving trolley moves along the transverse guide rail, it can drive the rotating lever to enter between the two convex columns of any one of the winding drums. When the rotating lever rotates between the two convex columns of any one of the winding drums, it can drive the winding drum to rotate.The anti - falling device includes vertical shafts arranged on the parking frames on both sides of each upper - layer parking space. At least two groups of vertical shafts are arranged on the parking frames on both sides of each upper - layer parking space. A transmission gear and a horizontal support plate are installed on each vertical shaft. The transmission gear can drive the horizontal support plate to rotate horizontally through the vertical shaft. A driving rack is arranged on one side of each transmission gear. The driving rack meshes with the transmission gear. Each driving rack is connected to the same anti - falling driving steel wire rope. An anti - falling device drum driven by a motor is installed on the parking frame. Both ends of the anti - falling driving steel wire rope are connected to the anti - falling device drum. When the anti - falling device drum rotates, it winds in the anti - falling driving steel wire rope on one side and releases the anti - falling driving steel wire rope on the other side. The anti - falling device drum can drive each driving rack to move synchronously through the anti - falling driving steel wire rope, so that each transmission gear rotates synchronously under the drive of the driving rack, thereby driving each horizontal support plate to switch between the state of coinciding with the parking frames on both sides of the upper - layer parking space and protruding into the upper - layer parking space. Both of the two convex columns on the drum are cylinders, and both ends of the rotating lever are arc - shaped. The movement of the moving frame in the access parking space is driven by a motor through a steel wire rope. The connecting and detaching connector between the moving frame and the car - carrying plate includes a cross - arm arranged on the side of the moving frame close to the car - carrying plate. A groove is opened on one side of the end of the cross - arm, and a column body matching the groove is arranged in the middle of the end of the car - carrying plate close to the moving frame. Tracks are arranged in the moving area of the servo bracket. Guide wheels are arranged at the bottom of the servo bracket, and the guide wheels cooperate with the tracks. The tracks are made of angle steel, and the tip of the angle steel faces downward so that the whole track is embedded below the ground in the moving area of the servo bracket. A triangular convex rib matching the track is arranged at the bottom of the servo bracket, and an installation groove is opened on the triangular convex rib. The guide wheels are installed in the installation groove, and the guide wheels can contact both inner sides of the track simultaneously.

[0006] The method for accessing vehicles by the three - dimensional vehicle storage device for an underground parking lot according to the present invention is as follows:

[0007] A vehicle - handing - over area is arranged in the moving area of the servo bracket. The vehicle - storing steps are as follows:

[0008] ①. After the vehicle - handing - over area barrier gate senses the arrival of a vehicle, the vehicle - storing management software reads the current vehicle - storing data and judges whether the parking spaces are full. If the parking spaces are full, the vehicle is prohibited from driving into the vehicle - handing - over area through the barrier gate;

[0009] If the parking spaces are not full, it is first judged whether there are idle car - carrying plates in each lower - layer parking space;

[0010] ②. If it is found that there are idle car - carrying plates in the lower - layer parking spaces after performing step ①, the servo bracket (16) moves towards the nearest lower - layer parking space with an idle car - carrying plate from its current position until the access parking space of the servo bracket (16) is aligned with the transverse moving bracket (15) in the lower - layer parking space;

[0011] If it is found that there is no idle car carrier in the lower parking space after step ①, it is determined that there is an idle car carrier in the upper parking space. At this time, the servo bracket (16) moves to the lower parking space below the upper parking space with the idle car carrier closest to its current position. Meanwhile, the parking management software determines whether there is a lateral transfer bracket (15) in the lower parking space below the upper parking space. If there is a lateral transfer bracket (15) in the lower parking space below the upper parking space, the lateral transfer bracket (15) is moved to an adjacent lower parking space, and the lifting bracket (4) of the upper parking space is lowered into the lower parking space below; if there is no lateral transfer bracket (15) in the lower parking space below the upper parking space, the lifting bracket (4) of the upper parking space is directly lowered into the lower parking space below until the access parking space of the servo bracket (16) is aligned with the lifting bracket (4) in the lower parking space.

[0012] ③. The moving frame (26) in the access parking space moves towards the lateral transfer bracket (15) or the lifting bracket (4) aligned with the access parking space of the servo bracket (16) in step ② until the connecting piece on the moving frame (26) is connected to the car carrier on the lateral transfer bracket (15) or the lifting bracket (4) in the lower parking space. Then the moving frame (26) moves in the reverse direction to tow the car carrier into the access parking space of the servo bracket (16).

[0013] ④. The servo bracket (16) carries the car carrier described in step ③ and moves to the vehicle delivery area.

[0014] ⑤. The parking management software opens the barrier gate, allowing the driver to drive the vehicle to be parked into the vehicle delivery area and park the vehicle on the car carrier carried by the servo bracket (16) described in step ④.

[0015] ⑥. All passengers and drivers leave the vehicle to be parked described in step ⑤, and the barrier gate closes again.

[0016] ⑦. After the barrier gate closes, the servo bracket (16) carries the car carrier with the vehicle to be parked described in step ⑤ and returns to the position where the car carrier was taken out in step ③.

[0017] ⑧. When the servo bracket (16) returns to the position where the car carrier was taken out in step ③ in step ⑦ and aligns the access parking space with the lateral transfer bracket (15) or the lifting bracket (4) in the lower parking space at this position, the moving frame (26) moves towards the lower parking space direction, pushes the car carrier in the access parking space back onto the lateral transfer bracket (15) or the lifting bracket (4) in the lower parking space, and then the moving frame (26) resets.

[0018] ⑨. If the car carrier is taken out from the lateral transfer bracket (15) in step ③, the parking process is completed after the car carrier is pushed back in step ⑧.

[0019] If the vehicle carrier board is taken out from the lifting bracket (4) in step ③, after pushing the vehicle carrier board back in step ⑧, the lifting bracket (4) rises into the upper parking space, completing the parking procedure;

[0020] The vehicle retrieval procedure is as follows:

[0021] After the parking management software receives the user's vehicle retrieval instruction, the servo bracket (16) moves towards the lower parking space where the target vehicle is located or the lower parking space below the upper parking space where the target vehicle is located;

[0022] If the target vehicle is on the vehicle carrier board in the lower parking space, wait for the servo bracket (16) to reach the position where it is aligned with the transverse bracket (15) of the access parking space and this lower parking space;

[0023] If the target vehicle is on the vehicle carrier board in the upper parking space, the parking management software determines whether there is a transverse bracket (15) in the lower parking space below this upper parking space. If there is a transverse bracket (15) in the lower parking space below this upper parking space, move this transverse bracket (15) to the adjacent lower parking space, then lower the lifting bracket (4) of this upper parking space into the lower parking space below, and wait for the servo bracket (16) to reach the position where it is aligned with this lifting bracket (4); If there is no transverse bracket (15) in the lower parking space below this upper parking space, directly lower the lifting bracket (4) of this upper parking space into the lower parking space below, and wait for the servo bracket (16) to reach the position where it is aligned with this lifting bracket (4);

[0024] After the servo bracket (16) reaches the position where it is aligned with the transverse bracket (15) or the lifting bracket (4) where the target vehicle is located as described in step a in the access parking space, the moving frame (26) in the access parking space moves towards the transverse bracket (15) or the lifting bracket (4) that is aligned with the access parking space of the servo bracket (16) in step ② until the connecting piece on the moving frame (26) is connected to the vehicle carrier board with the target vehicle parked on this transverse bracket (15) or lifting bracket (4), and then the moving frame (26) moves in the reverse direction to tow the vehicle carrier board with the target vehicle parked on it into the access parking space of the servo bracket (16);

[0025] The servo bracket (16) carries the vehicle carrier board with the target vehicle parked on it as described in step b and moves to the vehicle delivery area;

[0026] The parking management software opens the barrier gate, allowing the driver to enter the vehicle delivery area and drive away the target vehicle;

[0027] After the target vehicle drives out of the vehicle delivery area, the parking management software determines whether there are other vehicles waiting to be parked. If there are other vehicles waiting to be parked, the servo bracket (16) carries the empty car carrier plate and stays in the parking area to wait for the next vehicle to drive in. Starting from step ⑤ of the parking procedure, the parking procedure is executed to park the vehicle; after the target vehicle drives out of the vehicle delivery area, the parking management software determines whether there are other vehicles waiting to be parked. If there are other vehicles waiting to be parked, the servo bracket (16) carries the empty car carrier plate and stays in the parking area to wait for the next vehicle to drive in. Starting from step ⑤ of the parking procedure, the parking procedure is executed to park the vehicle;

[0028] If there are no other vehicles waiting to be parked after the target vehicle drives out of the vehicle delivery area, the servo bracket (16) carries the empty car carrier plate and returns to the position where the car carrier plate was taken out in step b;

[0029] When in step e, the servo bracket (16) returns to the position where the car carrier plate was taken out in step b and aligns the access parking space with the lateral transfer bracket (15) or the lifting bracket (4) in the lower storage parking space at this position, the moving frame (26) moves towards the lower storage parking space direction, pushes the car carrier plate in the access parking space back onto the lateral transfer bracket (15) or the lifting bracket (4) in this lower storage parking space, and then the moving frame (26) resets;

[0030] If the car carrier plate was taken out from the lateral transfer bracket (15) in step b, the car pick-up procedure is completed after pushing the car carrier plate back in step f;

[0031] If the car carrier plate was taken out from the lifting bracket (4) in step b, after pushing the car carrier plate back in step f, the lifting bracket (4) rises to the upper storage parking space to complete the car pick-up procedure.

[0032] The advantages of the present invention are as follows: It can move the car carrier plates in the three-dimensional parking device set in the underground parking lot to the shared vehicle delivery area through the servo bracket, so that the vehicle access is completed in the vehicle delivery area. The access positions in the vehicle delivery area are fixed positions, and there are no brackets and lifting devices on both sides to hinder. It is more convenient for the driver and passengers to park and get on and off the vehicle. One or two managers can be arranged in the vehicle delivery area to guide the driver to park the vehicle. The managers do not need to conduct inspections, which greatly reduces the labor cost of the parking lot operation unit and the labor intensity of the managers, and can ensure that the storage of each vehicle is completed under the guidance of the managers, which is beneficial to reducing the occurrence frequency of vehicle damage caused by vehicle storage, etc. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0034] The three-dimensional vehicle storage device for an underground parking lot described in the present invention includes at least one group of vehicle storage frames 1, and each group of vehicle storage frames 1 is arranged side by side. N upper vehicle storage spaces are arranged side by side on the upper part of each group of vehicle storage frames 1, where N is greater than or equal to 2. Each upper vehicle storage space is provided with a lifting bracket 4. A corresponding lower vehicle storage space is arranged below each upper vehicle storage space. Each lifting bracket 4 can descend into the corresponding lower vehicle storage space below. A total of N - 1 transverse moving brackets 15 are arranged in the lower vehicle storage space. Each transverse moving bracket 15 is provided with a transverse moving driving device. Each transverse moving bracket 15 can move to an adjacent lower vehicle storage space under the drive of the transverse moving driving device. A servo bracket 16 is arranged on one side of the vehicle storage frame 1. At least one access vehicle storage space is arranged on the servo bracket 16. The servo bracket 16 can move along the width direction of each upper vehicle storage space and the lower vehicle storage space. When the servo bracket 16 moves, the access vehicle storage space on the servo bracket 16 can be docked with any one of the transverse moving brackets 15 and the lifting bracket 4 that has descended into the lower vehicle storage space. A vehicle-carrying plate 17 is placed on each of the lifting brackets 4 and the transverse moving brackets 15. The vehicle-carrying plate 17 is provided with rollers 18. When the access vehicle storage space on the servo bracket 16 is docked with any one of the transverse moving brackets 15 and the lifting bracket 4 that has descended into the lower vehicle storage space, the vehicle-carrying plate 17 can move between the servo bracket 16 and the transverse moving bracket 15 or the lifting bracket 4. A moving frame 26 is installed in each access vehicle storage space of the servo bracket 16. The moving frame 26 can move between one end of the access vehicle storage space away from the vehicle storage frame and one end of the access vehicle storage space close to the vehicle storage frame. A connecting piece that can be connected and separated is arranged between the moving frame 26 and the vehicle-carrying plate 17.

[0035] When the vehicle storage device described in the present invention is built in an underground parking lot, a vehicle handover area shared by each vehicle-carrying plate is set within the operating range of the servo bracket 16.

[0036] When accessing the vehicle, the car-carrying plates of the upper and lower parking spaces both enter and exit at ground level. The car-carrying plates are transported to and retrieved from the vehicle delivery area through the servo bracket 16, realizing the automatic picking and placing of the car-carrying plates.

[0037] When constructing a multi-level parking garage in an existing underground parking lot, a passage for the vehicle to turn and enter the car-carrying plate needs to be reserved in the vehicle entry direction, and the width of this passage should not be less than 6 meters. However, in the vehicle of the present invention, it directly enters and exits the parking space on the car-carrying plate and is driven by the servo bracket 16 to move horizontally. As long as the length of the servo bracket 16 can exceed the total length of the vehicle, it can meet the usage requirements. For storing general household vehicles, setting the total length of the servo bracket 16 to 5 meters - 5.5 meters is sufficient to meet the usage requirements. Therefore, the present invention is beneficial to improving the space utilization rate of the underground parking lot.

[0038] Since facilities such as fire pipes and ventilation ducts need to be installed on the top of the underground parking lot, in the construction of a multi-level parking garage in the existing underground parking lot, the facilities on the top of the parking lot are all installed on the top of the vehicle passage on one side of the multi-level parking space to avoid interference between the facilities on the top of the parking lot and the multi-level parking space. In the three-dimensional vehicle storage device for an underground parking lot provided by this application, the vehicle transfer process of the servo bracket 16 is completed on the ground and does not occupy the upper space. Therefore, during the construction of the present invention, the facilities on the top of the parking lot can be installed on the top of the operation passage of the servo bracket 16, and there will also be no interference with the parking space.

[0039] The present invention can move the car-carrying plate in the three-dimensional vehicle storage device arranged in the underground parking lot to the shared vehicle delivery area through the servo bracket, so that the access of the vehicle is completed in the vehicle delivery area. The access positions in the vehicle delivery area are fixed positions, and there are no brackets and lifting devices on both sides to obstruct. It is more convenient for the driver and passengers to park and get on and off the vehicle. With 1 - 2 managers arranged in the vehicle delivery area, they can guide the driver to park the vehicle, and the managers do not need to conduct inspections, greatly reducing the labor cost of the parking lot operation unit and the labor intensity of the managers, and enabling the storage of each vehicle to be completed under the guidance of the managers, which is beneficial to reducing the occurrence frequency of vehicle damage caused by vehicle storage.

[0040] The transverse movement drive device on each transverse movement bracket 15 of the present invention can adopt various drive structures such as a motor driving a traveling drive wheel 30, a gear rack, etc., and cooperate with existing sensing devices such as proximity switches and infrared sensors to realize the movement and positioning of the transverse movement bracket 15.

[0041] The movement of the servo carriage 16 described in the present invention can be achieved through various structures such as motor-driven traveling wheels, gear racks, etc. in cooperation with a guiding and positioning device. Among them, the preferred structure is as follows: A track 22 is provided within the movement area of the servo carriage 16, and guide wheels 23 are provided at the bottom of the servo carriage 16. The guide wheels 23 cooperate with the track 22. A double-shaft motor is installed on the servo carriage 16, and a reel is installed on each of the two output shafts of the double-shaft motor. The two reels rotate synchronously. The wire rope ends of the two reels are respectively fixed at both ends of the track 22 within the movement area of the servo carriage 16. When the double-shaft motor drives the two reels to rotate synchronously, one reel winds up the wire rope and the other reel releases the wire rope, driving the servo carriage 16 to move along the track 22. Compared with other driving structures, this structure is more suitable for long-distance driving, with lower failure rates and maintenance requirements.

[0042] The movement of the moving frame 26 described in the present invention within each storage and retrieval position of the servo carriage 16 can adopt various driving structures such as lead screw nuts. Among them, it is preferably to drive the movement of the moving frame 26 within the storage and retrieval position by a motor driving a wire rope.

[0043] The connecting and disconnecting connector between the moving frame 26 and the car carrier plate 17 described in the present invention includes a cross arm 19 provided on the side of the moving frame 26 close to the car carrier plate 17. A groove 20 is opened on one side of the end of the cross arm 19, and a column 21 that cooperates with the groove 20 is provided in the middle of one end of the car carrier plate 17 close to the moving frame 26. When the servo carriage 16 is about to retrieve a certain target car carrier plate, the servo carriage 16 will move towards the position where the target car carrier plate is located. When the storage and retrieval position on the servo carriage 16 is about to align with the target car carrier plate, the moving frame 26 within this storage and retrieval position moves to one end close to the car storage frame. At this time, the groove 20 on one side of the cross arm 19 aligns with the column 21 on the car carrier plate. When the storage and retrieval position on the servo carriage 16 aligns with the target car carrier plate, the column 21 is located within the groove 20 on one side of the cross arm 19. At this time, the moving frame 26 moves in the reverse direction to pull out the target car carrier plate into the storage and retrieval position on the servo carriage 16. When the servo carriage 16 is about to put back a certain target car carrier plate, the servo carriage 16 moves to the retrieval position of the target car carrier plate, and then the moving frame 26 moves towards one end close to the car storage frame. As the moving frame 26 moves, the cross arm 19 pushes the column 21 on the car carrier plate through the groove 20 to push the target car carrier plate back to the retrieval position. At this time, the servo carriage 16 moves horizontally a certain distance to separate the groove 20 of the cross arm 19 from the main body 21 of the car carrier plate, and then the moving frame 26 returns to the storage and retrieval position on the servo carriage 16. The above structure is reliably connected and conveniently driven. The retrieval and placement of the car carrier plate are both achieved through the driving devices of the moving frame 26 and the servo carriage 16 itself, without the need to set up an additional power source. In addition to the above structure, the connecting and disconnecting connector described in the present invention can also be realized by other various structures such as electric control pins.

[0044] The lifting of each lifting bracket 4 of the present invention can be achieved through various driving structures such as hydraulic cylinders, gear racks, etc. The preferred driving structure is as follows: at least two groups of fixed pulleys 3 are provided on each parking frame 1 on both sides of each upper parking space, a winding drum 6 is provided on the parking frame 1 at one end of each upper parking space, at least two groups of lifting steel wires 5 are provided on both sides of the lifting bracket 4, each lifting steel wire 5 bypasses a fixed pulley 3 at its corresponding position and then is connected to the winding drum 6. When the winding drum 6 rotates, it can synchronously wind and unwind each lifting steel wire 5. This structure has stable lifting, low failure rate, high reliability, is convenient for centralized control, and has a lower cost.

[0045] In order to further reduce the self-cost of the lifting device of the lifting bracket 4 of the present invention, the following structure can be adopted: anti-falling devices 7 are provided on the parking frames 1 on both sides of each upper parking space. When the lifting bracket 4 rises to the upper parking space, the anti-falling device 7 can lock the height of the lifting bracket 4 to prevent the lifting bracket 4 from falling. A transverse guide rail 8 is provided along the width direction of each upper parking space at the top of the parking frame 1, a transverse moving trolley 9 is installed on the transverse guide rail 8, walking wheels 10 are provided on the transverse moving trolley 9, the walking wheels 10 are connected to the output shaft of a walking motor, and the walking motor can drive the transverse moving trolley 9 to move along the transverse guide rail 8 through the walking wheels 10. A lifting drive motor 12 is provided on the transverse moving trolley 9, the output shaft of the lifting drive motor 12 is connected to the middle of a rotating lever 13, and the lifting drive motor 12 can drive the rotating lever 13 to rotate. Two convex columns 14 are provided on one end face of the winding drum 6 of each upper parking space, the two convex columns 8 are located on the same diameter of the end face of the winding drum 6 and are symmetric with respect to the center of the circle of the end face of the winding drum 6. When the transverse moving trolley 9 moves along the transverse guide rail 8, it can drive the rotating lever 13 to enter between the two convex columns 14 of any winding drum 6. When the rotating lever 13 rotates between the two convex columns 14 of any winding drum 6, it can drive the winding drum 6 to rotate. The above structure can achieve that the lifting brackets 4 of each upper parking space are all driven to lift by the same lifting drive motor 12, without setting an independent lifting motor for each lifting bracket 4, significantly reducing the self-cost of the lifting device of the lifting bracket 4.

[0046] The above anti - falling device can adopt various structures. For example, on both sides of the parking frames 1 of each upper - layer parking space, a bolt driven by an electric push rod is set, etc. The preferred structure is as follows: The anti - falling device includes vertical shafts 101 arranged on both sides of the parking frames 1 of each upper - layer parking space. At least two groups of vertical shafts 101 are arranged on both sides of the parking frames 1 of each upper - layer parking space. A transmission gear 102 and a horizontal support plate 103 are installed on each vertical shaft 101. The transmission gear 102 can drive the horizontal support plate 103 to rotate horizontally through the vertical shaft 101. A driving rack 104 is arranged on one side of each transmission gear 102. The driving rack 104 meshes with the transmission gear 102. Each driving rack 104 is connected to the same anti - falling driving steel wire rope 105. An anti - falling device drum 106 driven by a motor is installed on the parking frame 1. Both ends of the anti - falling driving steel wire rope 105 are connected to the anti - falling device drum 106. When the anti - falling device drum 106 rotates, it winds in the anti - falling driving steel wire rope 105 on one side and releases the anti - falling driving steel wire rope 105 on the other side. The anti - falling device drum 106 can drive each driving rack 104 to move synchronously through the anti - falling driving steel wire rope 105, so that each transmission gear 102 rotates synchronously under the drive of the driving rack 104, thereby driving each horizontal support plate 103 to switch between the state of coinciding with the parking frames 1 on both sides of the upper - layer parking space and protruding into the upper - layer parking space. The above structure connects the actions of each horizontal support plate 103 into one body through the same anti - falling driving steel wire rope 105 and is jointly driven by the anti - falling device drum 106. The anti - falling and unlocking actions of each horizontal support plate 103 are completed synchronously, having the advantages of convenient control and rapid response.

[0047] In order to avoid the situation that the rotary lever 13 cannot smoothly enter between the two convex columns 14 on the drum 6 when the rotary lever 13 coincides with the two convex columns 14 on the drum 6, the two convex columns 14 on the drum 6 can be made into cylinders, and both ends of the rotary lever 13 are made into arcs. When the arc - shaped end of the rotary lever 13 contacts the cylindrical convex column 14, the rotary lever 13 can deflect to one side by itself to avoid the convex column 14 blocking the rotary lever 13.

[0048] The track 22 of the present invention can adopt various structures such as channel steel, linear guide rails, etc. The preferred structure is as follows: The track 22 is made of angle steel. The tip of the angle steel faces downward so that the whole track 22 is embedded below the ground in the moving area of the servo bracket 16. A triangular convex rib 24 matching the track 22 is arranged at the bottom of the servo bracket 16. An installation groove 25 is opened on the triangular convex rib 24. The guide wheel 23 is installed in the installation groove 25. The guide wheel 23 can contact both inner sides of the track 22 at the same time. This structure can enable the servo bracket 16 to move closely to the ground, enabling the vehicle to easily drive onto the servo bracket 16. And the guide wheel 23 is pushed on both sides in the installation groove 25, and can always move in the middle of the angle steel, so that the lateral frictional resistance during the operation of the servo bracket 16 is relatively low. The guide wheel 23 preferably adopts a spherical guide wheel. When the guide wheel 23 is spherical, the frictional resistance is the lowest.

[0049] The method for accessing vehicles by the three-dimensional vehicle storage device for underground parking lots according to the present invention is as follows: A vehicle handover area is set within the moving area of the servo bracket 16, and the vehicle storage steps are as follows:

[0050] ①. After the gate in the vehicle handover area senses the arrival of a vehicle, the vehicle storage management software reads the current vehicle storage data and determines whether the vehicle storage spaces are full. If the vehicle storage spaces are full, the gate prohibits the vehicle from driving into the vehicle handover area;

[0051] If the vehicle storage spaces are not full, first determine whether there are any idle car carriers in the lower vehicle storage spaces;

[0052] ②. If it is found that there is an idle car carrier in the lower vehicle storage space after performing step ①, the servo bracket 16 moves towards the lower vehicle storage space with the nearest idle car carrier to its current position until the access position of the servo bracket 16 is aligned with the transverse moving bracket 15 in this lower vehicle storage space;

[0053] If it is found that there is no idle car carrier in the lower vehicle storage space after performing step ①, determine whether there is an idle car carrier in the upper vehicle storage space. At this time, the servo bracket 16 moves towards the lower vehicle storage space below the upper vehicle storage space with the nearest idle car carrier to its current position. Meanwhile, the vehicle storage management software determines whether there is a transverse moving bracket 15 in the lower vehicle storage space below this upper vehicle storage space. If there is a transverse moving bracket 15 in the lower vehicle storage space below this upper vehicle storage space, move this transverse moving bracket 15 to an adjacent lower vehicle storage space and lower the lifting bracket 4 of this upper vehicle storage space into the lower vehicle storage space below; if there is no transverse moving bracket 15 in the lower vehicle storage space below this upper vehicle storage space, directly lower the lifting bracket 4 of this upper vehicle storage space into the lower vehicle storage space below until the access position of the servo bracket 16 is aligned with the lifting bracket 4 in this lower vehicle storage space;

[0054] ③. The moving frame 26 in the access position moves towards the transverse moving bracket 15 or the lifting bracket 4 that is aligned with the access position of the servo bracket 16 in step ② until the connecting member on the moving frame 26 is connected to the car carrier on the transverse moving bracket 15 or the lifting bracket 4 in this lower vehicle storage space. Then, the moving frame 26 moves in the reverse direction to pull this car carrier into the access position of the servo bracket 16;

[0055] ④. The servo bracket 16 moves to the vehicle handover area with the car carrier described in step ③;

[0056] ⑤. The vehicle storage management software opens the gate, allowing the driver to drive the vehicle to be stored into the vehicle handover area and park the vehicle on the car carrier carried by the servo bracket 16 described in step ④;

[0057] ⑥. All passengers and drivers leave the vehicle to be stored described in step ⑤, and the gate closes again;

[0058] ⑦ After the barrier gate is closed, the servo bracket 16 carries the car carrier board parked with the vehicle to be stored in step ⑤ back to the position where the car carrier board was taken out in step ③;

[0059] ⑧ When the servo bracket 16 in step ⑦ returns to the position where the car carrier board was taken out in step ③ and aligns the access parking space with the transverse moving bracket 15 or the lifting bracket 4 in the lower storage parking space at this position, the moving frame 26 moves towards the lower storage parking space direction, pushes the car carrier board in the access parking space back onto the transverse moving bracket 15 or the lifting bracket 4 in this lower storage parking space, and then the moving frame 26 resets;

[0060] ⑨ If the car carrier board was taken out from the transverse moving bracket 15 in step ③, the vehicle storage step is completed after pushing the car carrier board back in step ⑧;

[0061] If the car carrier board was taken out from the lifting bracket 4 in step ③, after pushing the car carrier board back in step ⑧, the lifting bracket 4 rises to the upper storage parking space to complete the vehicle storage step;

[0062] The vehicle retrieval steps are as follows:

[0063] After the vehicle storage management software receives the user's vehicle retrieval instruction, the servo bracket 16 moves towards the lower storage parking space where the target vehicle is located or the lower storage parking space below the upper storage parking space where the target vehicle is located;

[0064] If the target vehicle is on the car carrier board in the lower storage parking space, wait for the servo bracket 16 to reach the position where it aligns with the transverse moving bracket 15 in the access parking space and this lower storage parking space;

[0065] If the target vehicle is on the car carrier board in the upper storage parking space, the vehicle storage management software determines whether there is a transverse moving bracket 15 in the lower storage parking space below this upper storage parking space. If there is a transverse moving bracket 15 in the lower storage parking space below this upper storage parking space, move this transverse moving bracket 15 to the adjacent lower storage parking space, then lower the lifting bracket 4 of this upper storage parking space to the lower storage parking space below, and wait for the servo bracket 16 to reach the position where it aligns with this lifting bracket 4 in the access parking space; if there is no transverse moving bracket 15 in the lower storage parking space below this upper storage parking space, directly lower the lifting bracket 4 of this upper storage parking space to the lower storage parking space below, and wait for the servo bracket 16 to reach the position where it aligns with this lifting bracket 4 in the access parking space;

[0066] After the servo bracket 16 reaches the position where it aligns with the transverse moving bracket 15 or the lifting bracket 4 where the target vehicle is located as described in step a in the access parking space, the moving frame 26 in the access parking space moves towards the transverse moving bracket 15 or the lifting bracket 4 that aligns with the access parking space of the servo bracket 16 in step ② until the connecting piece on the moving frame 26 is connected to the car carrier board with the target vehicle parked on this transverse moving bracket 15 or the lifting bracket 4, and then the moving frame 26 moves in the reverse direction to tow the car carrier board with the target vehicle parked on it into the access parking space of the servo bracket 16;

[0067] The servo bracket 16 carries the car carrier board with the target vehicle parked in step b and moves it to the vehicle handover area;

[0068] The parking management software opens the barrier gate, allowing the driver to enter the vehicle handover area and drive away the target vehicle;

[0069] After the target vehicle drives away from the vehicle handover area, the parking management software determines whether there are other vehicles waiting to be parked. If there are other vehicles waiting to be parked, the servo bracket 16 carries the empty car carrier board and stays in the parking area waiting for the next vehicle to drive in. Starting from step ⑤ of the parking procedure, the parking procedure is executed to park the vehicle. After the target vehicle drives away from the vehicle handover area, the parking management software determines whether there are other vehicles waiting to be parked. If there are other vehicles waiting to be parked, the servo bracket 16 carries the empty car carrier board and stays in the parking area waiting for the next vehicle to drive in. Starting from step ⑤ of the parking procedure, the parking procedure is executed to park the vehicle.

[0070] If there are no other vehicles waiting to be parked after the target vehicle drives away from the vehicle handover area, the servo bracket 16 carries the empty car carrier board and returns to the position where the car carrier board was taken out in step b;

[0071] When in step e the servo bracket 16 returns to the position where the car carrier board was taken out in step b and aligns the access parking space with the lateral transfer bracket 15 or the lifting bracket 4 in the lower-level parking space, the moving frame 26 moves towards the lower-level parking space direction, pushes the car carrier board in the access parking space back onto the lateral transfer bracket 15 or the lifting bracket 4 in this lower-level parking space, and then the moving frame 26 resets;

[0072] If the car carrier board taken out in step b is from the lateral transfer bracket 15, then after pushing back the car carrier board in step f, the vehicle retrieval procedure is completed;

[0073] If the car carrier board taken out in step b is from the lifting bracket 4, then after pushing back the car carrier board in step f, the lifting bracket 4 rises to the upper-level parking space to complete the vehicle retrieval procedure.

[0074] The above method for accessing and storing vehicles enables the access and storage of vehicles to be completed within the vehicle handover area. The access and storage positions within the vehicle handover area are fixed positions, and there are no brackets and lifting devices on both sides to obstruct. It is relatively convenient for the driver and passengers to park and get on and off the vehicle. With 1 - 2 management personnel set in the vehicle handover area, they can guide the driver to park the vehicle. The management personnel do not need to conduct inspections, greatly reducing the labor cost of the parking lot operation unit and the labor intensity of the management personnel, and can ensure that the storage of each vehicle is completed under the guidance of the management personnel, which is conducive to reducing the occurrence frequency of vehicle damage caused by vehicle storage.
