Description

Technical Field

[0001] The present invention relates to a lifting device for a three-dimensional garage, specifically a one-machine multi-board lifting device for a three-dimensional garage. 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 planning and construction speed of parking spaces far lags behind the growth rate of the number of automobiles. Therefore, the problem of parking difficulty in large and medium-sized cities is still intensifying year by year. To alleviate the problem of parking difficulty, technicians in this field have designed a lifting and traversing parking device that can store vehicles on two floors. Both the first floor and the second floor of this two-story three-dimensional parking device can store vehicles. When the second-floor car carrier board needs to descend, the first-floor car carrier board at the corresponding position of the car carrier board is moved away, so that the entry and exit of the two floors of vehicles do not need to avoid each other. This two-story parking device can effectively increase the number of parking spaces in the parking lot. All the existing lifting and traversing two-story parking devices on the market are equipped with independent lifting drive devices on each second-floor lifting car carrier board to drive the lifting of each car carrier board, and the equipment cost is relatively high. Summary of the Invention

[0003] The purpose of the present invention is to provide a one-machine multi-board lifting device for a three-dimensional garage, which can make multiple second-floor car carrier boards in a lifting and traversing garage share a set of lifting drive devices, significantly reducing the equipment cost of the garage itself.

[0004] To achieve the above object, the present invention is realized through the following technical solutions: It includes a parking frame. Multiple upper parking spaces are arranged side by side at the upper part of the parking frame. An elevating bracket capable of lifting is provided in each upper parking space. An anti-falling device is provided between each elevating bracket and the parking frame. The anti-falling device can fix each elevating bracket in the lifting position. At least two groups of fixed pulleys are provided on the parking frame on both sides of each elevating bracket. A reel is provided on the parking frame at one end of each upper parking space. At least two groups of lifting steel wires are provided on both sides of each elevating bracket. Each lifting steel wire bypasses a fixed pulley at its corresponding position and then is connected to the reel. When the reel rotates, it can synchronously wind and unwind each lifting steel wire. A transverse guide rail is arranged along the width direction of each upper parking space at the top of the parking frame. A transverse moving trolley is installed on the transverse guide rail. A traveling wheel is provided on the transverse moving trolley. The traveling wheel is connected to the output shaft of the traveling motor. The traveling motor can drive the transverse moving trolley to move along the transverse guide rail through the traveling wheel. An elevating drive motor is provided on the transverse moving trolley. The output shaft of the elevating drive motor is connected to the middle part of the rotating lever. The elevating drive motor can drive the rotating lever to rotate. Two convex columns are provided on one end face of the reel of each upper parking space. 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 reel. When the rotating lever rotates between the two convex columns of any one reel, it can drive the reel to rotate. The anti-falling device includes vertical shafts provided on the parking frames on both sides of each upper parking space. At least two groups of vertical shafts are provided on the parking frames on both sides of each upper 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 provided 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 drive steel wire. An anti-falling device reel driven by a motor is installed on the parking frame. Both ends of the anti-falling drive steel wire are connected to the anti-falling device reel. When the anti-falling device reel rotates, it winds in the anti-falling drive steel wire on one side and releases the anti-falling drive steel wire on the other side. The anti-falling device reel can drive each driving rack to move synchronously through the anti-falling drive steel wire, 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 parking space and protruding into the upper parking space. The two convex columns on the reel are both cylinders, and both ends of the rotating lever are arc-shaped. A first gear is installed on the output shaft of the elevating drive motor inside the transverse moving trolley. A second gear is provided on one side of the first gear. The second gear is installed on the screw rod. External threads are provided on the outer periphery of the screw rod. The second gear is matched with the screw rod through internal threads. A screw hole is opened on the bottom plate of the transverse moving trolley. The lower part of the screw rod is threadedly matched with the screw hole on the bottom plate of the transverse moving trolley. The lower end of the screw rod is connected to the middle part of the rotating lever. When the screw rod rotates relative to the second gear, it can move up and down relative to the second gear. A stop block is provided at the upper end of the screw rod. When the screw rod moves down relative to the second gear, the stop block can contact the second gear and prevent the screw rod from continuing to rotate relative to the second gear.One end of the drum is installed with a connecting plate, and two convex columns of the drum are both installed on the connecting plate. Four positioning screw holes are opened around the axis of the drum, and the positioning screw holes are evenly distributed with the axis of the drum as the center. Positioning bolts are inserted into the positions of the connecting plate corresponding to the positioning screw holes, and the cooperation between each positioning bolt and the positioning screw hole realizes the fixation of the connecting plate and the drum.

[0005] The advantages of the present invention are as follows: A set of lifting drive devices can be shared by multiple second-layer car carriers in the lifting and traversing garage, significantly reducing the equipment cost of the garage itself, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The multi-board lifting device of a three-dimensional garage according to the present invention includes a parking frame 1. Multiple upper parking spaces are arranged side by side at the upper part of the parking frame 1. Lifting brackets 4 capable of lifting are arranged in each upper parking space. Anti-falling devices are arranged between each lifting bracket 4 and the parking frame 1. The anti-falling devices can fix each lifting bracket 4 at the lifting position. At least two groups of fixed pulleys 3 are arranged on the parking frame 1 on both sides of each lifting bracket 4. A winding drum 6 is arranged on the parking frame 1 at one end of each upper parking space. At least two groups of lifting steel wires 5 are arranged on both sides of each 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. A transverse guide rail 8 is arranged 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. A walking wheel 10 is arranged on the transverse moving trolley 9. The walking wheel 10 is connected to the output shaft of a walking motor 11. The walking motor 11 can drive the transverse moving trolley 9 to move along the transverse guide rail 8 through the walking wheel 10. A lifting drive motor 12 is arranged 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. The lifting drive motor 12 can drive the rotating lever 13 to rotate. Two convex columns 14 are arranged on one end face of the winding drum 6 of each upper parking space. 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 one winding drum 6. When the rotating lever 13 rotates between the two convex columns 14 of any one winding drum 6, it can drive the winding drum 6 to rotate. The two convex columns 8 are located on the same diameter of the end face of the winding drum 6 and are symmetric about 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 one winding drum 6. When the rotating lever 13 rotates between the two convex columns 14 of any one winding drum 6, it can drive the winding drum 6 to rotate. The above structure can realize 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.

[0008] The anti-falling device of the present invention can adopt various structures. For example, a bolt driven by an electric push rod is provided on the parking frames 1 on both sides of each upper parking space. Among them, the preferred structure is as follows: The anti-falling device includes vertical shafts 101 provided on the parking frames 1 on both sides of each upper parking space. At least two groups of vertical shafts 101 are provided on the parking frames 1 on both sides of each upper 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 provided 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, the anti-falling driving steel wire rope 105 is wound inwards on one side and released outwards 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 parking space and protruding into the upper 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 commonly uses a double-connected drum 106 for driving. The anti-falling and unlocking actions of each horizontal support plate 103 are completed synchronously, having the advantages of convenient control and rapid response.

[0009] In order to prevent the rotating lever 13 from failing to smoothly enter between the two protruding columns 14 on the drum 6 when the rotating lever 13 coincides with the two protruding columns 14 on the drum 6, the two protruding columns 14 on the drum 6 can be made into cylinders, and both ends of the rotating lever 13 can be made into arcs. When the arc-shaped end of the rotating lever 13 contacts the cylindrical protruding column 14, the rotating lever 13 can deflect to one side by itself to prevent the protruding column 14 from blocking the rotating lever 13.

[0010] In order to prevent the rotary lever 13 from being blocked by the convex posts 14 when it moves out between the two convex posts 14 on a certain reel 6 and thus unable to move normally, the rotary lever 13 can be driven to reverse by the lifting drive motor 12 before the rotary lever 13 moves, so that the rotary lever 13 rotates to an angle coinciding with the moving direction, avoiding the rotary lever 13 being blocked by the convex posts 14. However, judging the angle of the rotary lever 13 requires precise sensing equipment and relatively precise control of the rotation angle of the lifting drive motor 12, and the cost of the control equipment is relatively high. To prevent the rotary lever 13 from being blocked by the convex posts 14, the following structure can also be adopted in this application: A first gear 2 is installed on the output shaft of the lifting drive motor 12 inside the transverse movement trolley 9. A second gear 15 is arranged on one side of the first gear 2. The second gear 15 is installed on a screw rod 16. The outer circumference of the screw rod 16 is provided with an external thread, and the second gear 15 is matched with the screw rod 16 through an internal thread. A screw hole 17 is opened on the bottom plate of the transverse movement trolley 9. The lower part of the screw rod 16 is in threaded cooperation with the screw hole 17 on the bottom plate of the transverse movement trolley 9. The lower end of the screw rod 16 is connected to the middle part of the rotary lever 13. When the screw rod 16 rotates relative to the second gear 15, it can move up and down relative to the second gear 15. A stop block 18 is arranged at the upper end of the screw rod 16. When the screw rod 16 moves down relative to the second gear 15, the stop block 18 can contact the second gear 15 and prevent the screw rod 16 from continuing to rotate relative to the second gear 15. When the rotary lever 13 needs to drive the reel 6 to rotate, the output shaft of the lifting drive motor 12 drives the second gear 15 to rotate forward through the first gear 2. After the rotary lever 13 contacts the convex posts 14, it remains stationary under the block of the convex posts 14. As the second gear 15 rotates forward, the screw rod 16 moves down relative to the second gear 15 until the stop block 18 at the upper end of the screw rod 16 contacts the second gear 15. At this time, there is no relative movement and rotation between the screw rod 16 and the second gear 15. The second gear 15 will drive the rotary lever 13 to push the convex posts 14 through the screw rod 16, thereby driving the reel 6 to rotate and driving the lifting bracket 4 to lift and lower. When the rotary lever 13 needs to move out between the two convex posts 14 on a certain reel 6, during the transverse movement of the rotary lever 13, it contacts the convex posts 14. The screw rod 16 can reverse and rise relative to the second gear 15, and the second gear 15 does not restrict the rotation of the screw rod 16. Therefore, the rotary lever 13 can smoothly rotate to an angle not affected by the convex posts 14 and move out. This structure does not require a complex electric control sensing device, nor does it require precise control of the rotation angle of the lifting drive motor 12. The cost is relatively low, and the operation is stable and reliable.

[0011] To avoid the situation where the two convex columns 14 are exactly in the position blocking the rotary lever 13 after the reel 6 is installed, the following structure can be adopted: A connecting plate 19 is installed at one end of the reel 6, and the two convex columns 14 of the reel 6 are both installed on the connecting plate 19. Four positioning screw holes 20 are opened around the axis of the reel 6, and the positioning screw holes 20 are evenly distributed with the axis of the reel 6 as the center. Positioning bolts 21 penetrate through the positions of the connecting plate 19 corresponding to the positioning screw holes 20, and the cooperation between each positioning bolt 21 and the positioning screw hole 20 realizes the fixation of the connecting plate 19 and the reel 6. In this structure, there are multiple matching angles between the connecting plate 19 and the reel 6. The connecting plate 19 can be fixed on the reel 6 by the positioning bolts 21 every time it rotates 90°. When installing the connecting plate 19 and the convex columns 14 on the reel 6, the positions of the convex columns 14 can be adjusted according to the actual situation to avoid exactly blocking the position of the rotary lever 13.
