DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The embodiment of the present application discloses a mechanical three-dimensional parking device of a vertically lifting large car type.

[0041] Example

[0042] according to Figures 1 to 10 As shown, a vertical lifting large car type mechanical three-dimensional parking equipment includes a frame 1, which is formed by a steel structure frame. The frame 1 is provided with a machine room 2, a lifting car 3, a lateral movement trolley, an intelligent transporter, an entrance and exit platform 39 and a control system. The machine room 2 is used to drive the lifting car 3 to move up and down. The lifting car 3 is used to lift and transport the lateral movement trolley, the intelligent transporter, and the vehicle. The control system is used to control the start or shut down of the machine room 2.

[0043] The parking personnel needs to park the vehicle at the entrance and exit platform 39, and then the machine room 2 operates to lift the lift car 3 to the entrance and exit layer (the lateral movement trolley can be moved horizontally and rotated during the lifting process). After the lift car 3 is in place, the intelligent transporter moves longitudinally or horizontally, and the intelligent transporter moves to the bottom of the vehicle to lift the vehicle and put it back on the lateral movement trolley. The machine room 2 operates again to lift the vehicle to the parking layer (the lateral movement trolley can be moved horizontally and rotated during the lifting process). After it is in place, the intelligent transporter transports the vehicle to the parking space, and the parking is completed. The lateral movement trolley, intelligent transporter, entrance and exit platform 39 and control system are all prior art and will not be described in detail here.

[0044] The lateral trolley transmission system is a dual-motor transmission, and the drive shaft connection position is connected by a coupling, which makes the lateral trolley highly synchronized. The flat-layer flipping mechanism aligns the lateral trolley guide surface with the steel structure track surface. The carrier transports the vehicle to the steel structure parking rack, which can effectively accurately locate the vehicle each time it is stored and retrieved, and play a role in preventing it from falling. The specific structure of the lateral trolley belongs to the prior art, see the patent document with application number CN202123296247.7 for details.

[0045] The entrance and exit parking platform is equipped with a vehicle anti-fall device, a car blocker device, biological monitoring, wheel detection, vehicle length, width, height, chassis, weight and other safety detections. The entrance and exit parking platform has a built-in anti-fall device that can effectively prevent the vehicle from falling. The car blocker device locates the wheels and detects whether the vehicle is parked in place. The chassis detection device can monitor the height of the vehicle chassis in real time. The settings and functions of the above-mentioned entrance and exit parking platforms belong to the prior art and will not be repeated here.

[0046] The machine room 2 includes a base frame 5, a double-output shaft motor 6 and a rotating shaft 7. The base frame 5 is installed on the top of the frame body 1. A double-output shaft motor 6 is installed in the middle of the top of the base frame 5. The two output shaft ends of the double-output shaft motor 6 are respectively connected to the rotating shaft 7 through couplings. Two driving gear sets are installed at intervals on the top of the base frame 5. The two driving gear sets are symmetrically connected to the ends of the two rotating shafts 7. The driving gear set includes a mounting seat A9. The two mounting seats A9 are symmetrically located at the ends of the two rotating shafts 7. Two rotating shafts A10 are arranged in parallel and at intervals in the mounting seat A9. The rotating shaft A10 is rotatably connected to the mounting seat A9 through a bearing. The two rotating shafts A10 have the same height. One end of the rotating shaft A10 is connected to the end of the rotating shaft 7 through a coupling. A synchronous gear 11 and a transmission gear A12 are fixed on the outer side of the rotating shaft A10. The two synchronous gears 11 are meshed, and the two transmission gears A12 are arranged at intervals.

[0047] A driven gear set is installed at the top four corners of the bottom frame 5. The driven gear set includes a mounting seat B13. A rotating shaft B14 and a rotating shaft C15 are arranged in parallel and spaced apart in the mounting seat B13. The heights of the rotating shaft B14 and the rotating shaft C15 are different. The height of the rotating shaft B14 is greater than the height of the rotating shaft C15. Both ends of the rotating shaft B14 and both ends of the rotating shaft C15 are fixedly connected to the mounting seat B13. The outer side of the rotating shaft B14 is rotatably connected to a transmission gear B16 through a bearing. The outer side of the rotating shaft C15 is rotatably connected to a transmission gear C17 through a bearing. The transmission gear B16 and the transmission gear C17 are arranged at intervals. Both ends of the rotating shaft B14 and both ends of the rotating shaft C15 are sleeved with U-shaped hooks 18. The two ends of the U-shaped hooks 18 are respectively inserted into the corresponding positioning holes opened in the mounting seat B13.

[0048] The lift car 3 is symmetrically provided with counterweights 4 on both sides, and the lift car 3 is equipped with various safety detection devices such as lifting laser safety detection, photoelectric switch, limit switch, and electrical control system. The counterweight 4 is a balancing device during the lifting and running of the lift car 3, the traverse trolley, the carrier, and the vehicle. The role of the lifting laser safety detection is to detect the height distance of the lift car 3 in real time. When the equipment is running to store and retrieve the vehicle, the lifting laser detection controls the layered positioning of the lift car 3. The photoelectric switch includes a strong deceleration photoelectric switch and a layer positioning photoelectric switch. Among them, the role of the strong deceleration photoelectric switch is to decelerate in advance when the lift car 3 is lifted to the top or bottom layer, so that the lift car 3 has a lifting buffer zone, and the role of the layer positioning photoelectric switch is a secondary protection for the layered positioning. The limit switch can detect the total travel distance of the equipment, control the upper and lower limits of the lift car 3, and prevent the lift car 3 from exceeding the predetermined travel. The lifting laser safety detection, the strong deceleration photoelectric switch, the layer positioning photoelectric switch, the limit switch, and the electrical control system are all prior art and will not be described here.

[0049] The lifting car 3 includes a car frame welded body 35, which is located inside the frame 1. The side of the car frame welded body 35 is slidably connected to the inner wall of the frame 1 up and down. The car frame welded body 35 is located below the frame 5. Counterweight bodies 4 are symmetrically arranged on both sides of the car frame welded body 35. The side of the counterweight body 4 is slidably connected to the inner wall of the frame 1 up and down.

[0050] The top four corners and the bottom four corners of the car frame welded body 35 are respectively installed with guide wheel groups, and the guide wheel group includes a fixed seat 19, one side of the fixed seat 19 is detachably connected to the side wall of the lifting car 3 by bolts, and the other side of the fixed seat 19 is fixedly connected to two vertical plates 20, the sides of the two vertical plates 20 intersect, and the angle between the two vertical plates 20 is a right angle. A long hole 37 is opened in the center of the vertical plate 20, and a rotating shaft D36 is inserted and fixed in the long hole 37. One end of the rotating shaft D36 is rotatably connected to the guide wheel 21 through a bearing, and the other end of the rotating shaft D36 is threadedly connected to the fixing nut 22, and the side of the vertical plate 20 away from the guide wheel 21 is fixedly connected. A connecting plate 23 is connected, and a washer A28 is arranged between the connecting plate 23 and the fixing nut 22. The end of the vertical plate 20 away from each other is fixedly connected to the support plate 24. A U-shaped opening 25 is horizontally opened at one end of the support plate 24. An adjusting rod 26 is inserted in the U-shaped opening 25. One end of the adjusting rod 26 points to the outside of the fixing nut 22. The two ends of the adjusting rod 26 are respectively threadedly connected to the limiting nuts 27. The two limiting nuts 27 are respectively located on both sides of the support plate 24. The adjusting rod 26 is sleeved with two washers B29 at intervals. The two washers B29 are located between the two limiting nuts 27. The two washers B29 are respectively located on both sides of the support plate 24. The car frame welded body 35 slides relative to the lifting guide rail 38 of the inner side wall of the frame body 1 through the guide wheel 21, thereby improving the stability of the car frame welded body 35 during the lifting process.

[0051] A chain 8 is wound and meshed between two adjacent transmission gears A12 and B16, one end of the chain 8 passes through the transmission gear A12 and the transmission gear C17 downward in sequence and extends downward to be fixedly connected to the top of the car frame welded body 35 in the lift car 3, and the other end of the chain 8 passes through the transmission gear B16 downward to be fixedly connected to the upper end of the counterweight body 4. The four chains 8 establish a balanced relationship between the car frame welded body 35 and the counterweight body 4 for upward and downward movement.

[0052] The four corners of the top of the car frame welded body 35 are equipped with chain 8 hanging point devices, which include a connecting seat 30, which is fixedly connected to the top of the car frame welded body 35, and a connecting rod 31 is vertically inserted and fixed on the top of the connecting seat 30, and a connecting block 32 is fixedly connected to the top of the connecting rod 31, and two clamping plates 33 are arranged at intervals in parallel on the top of the connecting block 32, and the two clamping plates 33 are symmetrically provided with connecting holes 34, which are used to accommodate the end of the chain 8, and the connecting hole 34 is fixed to the end of the chain 8 by inserting screws.

[0053] The machine room 2 provides power for the lift car 3 to move up and down. A double-output shaft motor 6 is used in the machine room 2 to synchronously drive the two rotating shafts 7 to rotate, and the transmission gear A12 and the chain 8 in the two mounting seats A9 are linked and synchronized to the four lifting points of the lift car 3. The chain 8 establishes a lifting and balanced connection between the lift car 3 and the counterweight 4. The gear linkage is safe and stable, with high precision, good synchronization, low cost, and easy maintenance.

[0054] The guide wheel group installed at the four corners of the lift car 3 adopts a double-wheel design, which can improve the stability and reliability of the four corners of the lift car 3, effectively increase the stability of the car during the lifting process, and reduce the generation of noise. The guide wheel group is designed with an adjustment rod 26, which can adjust the position of the rotating shaft D36 in the long hole 37 according to the installation error, and then adjust the position of the guide wheel 21.

[0055] The double-axle motor 6 rotates by driving the rotating shaft 7, and the rotating shaft 7 rotates synchronously to drive the two active gear sets to rotate. The active gear set cooperates with the driven gear set through the chain 8 to achieve the lifting balance between the lift car 3 and the counterweight 4. Only one double-axle motor 6 is needed to drive the two rotating shafts 7 to rotate at the same time, so that the lift car 3 and the counterweight 4 can be lifted and lowered synchronously in opposite directions. The structure is simple, the cost is low, the operation is convenient and fast, the synchronization is good, the stability is high, and it is easy to maintain. The four chains 8 can evenly transmit power to the lift car 3 and the counterweight 4, so that the top four corners of the lift car 3 and the top two ends of the counterweight 4 are evenly stressed, thereby improving the stability of the lift car 3 and the counterweight 4 during the lifting process.

[0056] The meshing of the two synchronous gears 11 can ensure that the rotating shaft A10 connected to the rotating shaft 7 can transmit power to the other rotating shaft A10, ensuring that the two rotating shafts A10 can rotate synchronously, and then ensuring that the two transmission gears A12 rotate synchronously, so that the four corners of the machine room 2 can be synchronously driven by the chains 8, so that the four chains 8 can synchronously pull the lift car 3 to move up and down. The height of the rotating shaft B14 is different from the height of the rotating shaft C15, which is conducive to providing space for the winding of the chain 8, so that both ends of the same chain 8 can extend downward to connect with the lift car 3 and the counterweight 4 respectively, so that the four corners of the lift car 3 can be evenly stressed, improving the stability and safety of the lift car 3 during the lifting process. The U-shaped hook 18 can improve the stability of the rotating shaft B14 and the rotating shaft C15.

[0057] The design of the two guide wheels 21 in the guide wheel group enables the top and bottom of the lift car 3 to maintain smooth sliding with the side wall of the frame 1, thereby improving the stability and safety of the lift car 3 during the lifting process. The washer A28 can improve the firmness of the connection between the connecting plate 23 and the fixing nut 22, and the washer B29 can improve the tightness and firmness of the connection between the limit nut 27 and the support plate 24.

[0058] The ends of the chain 8 can be accommodated between the two clamping plates 33 and the connecting hole 34 in the chain 8 hanging point device. With the help of screws, the flexibility of the connection between the chain 8 and the lift car 3 can be achieved, which facilitates the installation and disassembly of the chain 8 and the lift car 3.

[0059] Working principle:

[0060] The double-output shaft motor 6 is started to work, and the output shaft of the double-output shaft motor 6 rotates, driving the two rotating shafts 7 to rotate synchronously. The two ends of the rotating shaft 7 rotate by driving the synchronous gear 11, so that the transmission gear A12 rotates synchronously. The transmission gear A12 drives the transmission gear B16 and the transmission gear C17 to rotate through the chain 8 during the rotation process. The transmission gear B16 drives the lift car 3 to move upward through the chain 8 during the rotation process. The transmission gear C17 drives the counterweight body 4 to move downward through the chain 8 during the rotation process. The lift car 3 and the counterweight body 4 achieve balance during the lifting process. Similarly, when the output shaft of the double-output shaft motor 6 rotates in the opposite direction, the lift car 3 moves downward and the counterweight body 4 moves upward.
