Description

Technical Field

[0001] The utility model relates to the field of stereo garages, in particular to a stereo garage lifting device and a stereo garage composed of the same. Background Art

[0002] With the development of parking garages, dedicated vehicle lifting equipment is often needed to facilitate the transportation of vehicles to different levels for storage and retrieval. This not only replaces the ramps used for vehicles to enter and exit the garage, but also significantly saves space and improves garage utilization. Difficulty parking and traffic congestion are also concerns affecting the development of the automotive industry. The construction of small, highly intelligent, and multi-story parking garages is an effective way to alleviate this problem.

[0003] The prior art CN201610489213.4 discloses a stereoscopic parking garage, comprising a driving frame, a guide frame, a fixed beam, a closed guide rail, a lifting chain, a driving shaft, a supporting frame, a lifting chain piece and a guide rail; the driving frame and the guide frame are a frame structure welded with square steel pipes, the fixed beam is fixedly connected between the driving frame and the guide frame and together with the driving frame and the guide frame constitute a load-bearing and force-bearing main body; a closed guide rail is respectively provided in the vertical frame of the driving frame and the guide frame, the closed guide rail is provided with a lifting chain, the lifting chain circulates in the closed guide rail and forms a lifting system with the closed guide rail; the guide rail is arranged on the outer side of the guide frame, a plurality of lifting chain pieces are evenly distributed on the lifting chain, a plurality of supporting frames are arranged in parallel and horizontally between the corresponding two lifting chains, and the hinge shafts on the cross beams on both sides of each supporting frame are hinged to the corresponding lifting chain piece; although this stereoscopic parking garage can effectively reduce the ground occupied area and improve parking efficiency, it still has the following problems:

[0004] 1. Most of the stereo garages use a sprocket formed by a combination of a paddle wheel and a gear to engage with the chain for transmission. However, most of the paddle wheels and gears are solid structures, which have high production costs. In addition, additional processes are required to fix the paddle wheel and the gear to ensure the rotation between the drive device and the sprocket and the sprockets on both sides, resulting in a complex transmission structure.

[0005] 2. The existing sprocket is heavy, which not only increases the burden on the entire lifting system and leads to increased energy consumption, but also places higher requirements on the motor and other transmission components due to inertia during starting and stopping, accelerates the aging and damage of these components, and affects the response speed and control accuracy of the equipment.

[0006] 3. The larger mass of the solid sprocket means that it has greater inertia during dynamic operation, which will affect the response speed and control accuracy of the lifting system. Especially in the case of rapid start and emergency stop, the inertia of the solid sprocket may cause the system to react slowly and increase safety risks. Utility Model Content

[0007] In view of this, the purpose of the present invention is to provide a three-dimensional parking garage lifting device and the three-dimensional parking garage composed thereof. By adopting a hollow sprocket instead of the traditional solid gear to combine with the paddle wheel (sprocket), it not only reduces the weight of the sprocket and reduces the material cost, but also ensures the smoothness and reliability of the lifting process.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] Provided is a three-dimensional parking garage lifting device and a three-dimensional parking garage composed thereof, including: a driving device, a transmission device, a supporting wheel, a hollow sprocket and a chain,

[0010] The supporting wheel is rotatably arranged on the garage frame, the hollow sprocket support sleeve is arranged on the outside of all the supporting wheels distributed in a circle, the chain is sleeved on the corresponding hollow sprocket, and the driving device is arranged on the corresponding garage frame; the transmission device includes a transmission shaft and a transmission gear, the two ends of the transmission shaft are arranged on the garage frame through bearing seats and are connected to the driving device for transmission, and the transmission gear is arranged at both ends of the transmission shaft and meshes with the corresponding hollow sprocket for transmission.

[0011] It should be noted that the garage frame is the basic structure of the entire stereo garage. The drive device is connected to the transmission device, which in turn drives the hollow sprocket to rotate. Belt drive, gear drive, and chain drive can be used between the transmission device and the drive device. The specific selection should be based on actual working conditions and cost considerations. For example, gear drive can be selected in situations where high precision and high efficiency are required; belt drive can be selected in situations where shock absorption and noise reduction are required. The use of a drive shaft can enable the hollow sprockets on both sides to rotate synchronously. This solution uses a hollow sprocket instead of the traditional combination sprocket of solid gears and paddle wheels. This not only reduces the weight of the sprocket and reduces material costs, but also reduces the load of the entire lifting system and energy consumption. It also reduces the inertia effect during starting and stopping, improves the system's response speed and control accuracy, thereby improving safety. By reducing the use of additional paddle wheels, the number of system components is reduced, making maintenance more convenient and quick. At the same time, the design of the support wheel helps to reduce friction, making the sprocket easier to rotate, and improving the efficiency of the entire system.

[0012] Preferably, the hollow sprocket includes a driven sprocket and a driving sprocket, and the driven sprocket and the driving sprocket are respectively arranged at the upper and lower ends of the garage frame, the chain is engaged with the corresponding driven sprocket and driving sprocket, the transmission device is arranged on the garage frame between the driven sprocket and the driving sprocket, and the transmission gear can be engaged with the driving sprocket for transmission.

[0013] It should be noted that the driving sprocket is located at the lower end of the garage frame. It not only meshes with the transmission gear, but also meshes with the chain, achieving the effect of "one wheel for multiple uses"; specifically: the driving sprocket meshes with the transmission gear, receives power from the drive device, and then the driving sprocket transmits the power to the driven sprocket through the chain to realize the lifting and lowering of the parking platform; the driven sprocket is located at the upper end of the garage frame and is connected to the driving sprocket through a chain. The main function of the driven sprocket is to support the chain and ensure that the chain remains tensioned during operation to prevent tooth jumping caused by chain relaxation.

[0014] Preferably, the pitch of the chain is N times the pitch of the driving sprocket, and N is an integer greater than or equal to 2.

[0015] It should be noted that the chain pitch refers to the distance between the centers of two adjacent chain pins, and the sprocket pitch refers to the distance between the centers of two adjacent sprocket teeth. By setting the chain pitch to an integer multiple of the sprocket pitch, the meshing of the chain and sprocket can be ensured to be smoother, wear can be reduced, and transmission efficiency can be improved. In addition, a longer chain pitch can reduce the chain's tooth skipping during operation, improving the stability and reliability of the system. For example: N = 2: If the sprocket pitch is 10mm, the chain pitch is 20mm. This design can significantly reduce the number of chain sections and reduce the total weight of the chain while maintaining good meshing performance. N = 3: If the sprocket pitch is 10mm, the chain pitch is 30mm. This design further reduces the number of chain sections and is suitable for applications requiring higher stability and lower noise.

[0016] Preferably, the tooth pitch of the driven sprocket is the same as the pitch of the chain.

[0017] It should be noted that the tooth pitch of the driven sprocket is the same as the pitch of the chain, which ensures perfect engagement between the chain and the driven sprocket, reduces impact and wear during the transmission process, and improves the operating efficiency and stability of the system.

[0018] Preferably, the supporting wheel of the driving sprocket is fixed to the lower end of the garage frame through a fixing frame, and the supporting wheel of the driven sprocket is arranged on the upper end of the garage frame through an adjusting frame, and the adjusting frame is adjustably arranged on the garage frame through an adjusting device.

[0019] It should be noted that the fixing frame and the adjusting frame are usually a solid steel structure, which is fixed to the garage frame by welding or bolts, ensuring the stability and reliability of the supporting roller, so that the hollow sprocket can stably support the chain and transmit power; and the design of the fixing frame and the adjusting frame allows the supporting roller to be replaced as a whole, simplifying the maintenance process and reducing maintenance time and cost.

[0020] Preferably, the adjusting device is an adjusting screw, which passes through the crossbeam at the top of the garage frame and is connected to the corresponding adjustment link, and the spacing between the driving sprocket and the driven sprocket can be adjusted by rotating the adjusting screw.

[0021] It should be noted that the adjusting screw is a common mechanical adjustment device. By rotating the screw, the position of the driven sprocket can be accurately adjusted. By rotating the adjusting screw, the position of the adjusting frame on the garage frame can be changed, thereby adjusting the distance between the driven sprocket and the driving sprocket. This design can ensure that the chain always maintains appropriate tension and avoids tooth jumping and wear caused by the chain being too loose or too tight.

[0022] Preferably, the fixing frame and the adjusting frame are both square frames, and the supporting wheels are evenly distributed in pairs on the four sides of the square frame.

[0023] It should be noted that the fixed frame and the adjustment frame structure can be rotated according to needs. The square frame is designed as the preferred option in this solution. This design is not only simple in structure, but also has high rigidity and stability, and can effectively support the supporting wheels and sprockets; the supporting wheels are evenly distributed in pairs on the four sides of the square frame. This arrangement can ensure that the supporting wheels are evenly distributed in all directions, reduce local uneven force, and improve the overall balance and stability of the system.

[0024] Preferably, a driven gear is provided on the transmission shaft, and the driven gear is connected to the driving device through a transmission chain, and the transmission ratio between the driven gear and the driving device is 1:2-1:5.

[0025] It should be noted that the driven gear is connected to the drive device through a transmission chain. This method can effectively transmit power and has a certain degree of flexibility, which can absorb some vibrations and reduce noise. The transmission ratio can be adjusted according to actual lifting needs. A transmission ratio of 1:2-5 means that the speed of the drive device is 2-5 times the speed of the drive shaft, that is, the drive shaft rotates one circle for every 2-5 turns of the drive device. This design can achieve the effect of deceleration and torque increase, so that the lifting device can provide greater lifting force, which is suitable for vehicle lifting under heavy load conditions. By deceleration and torque increase, the impact of the system when starting and stopping can be reduced, and the smooth operation of the system can be improved.

[0026] A three-dimensional parking garage comprising any one of the above-mentioned lifting devices, a garage frame, a parking platform and a guide device;

[0027] The lifting device is arranged on the garage frame, and the garage frame includes two symmetrically arranged vertical door frames. Suspension plates are provided at intervals on the outer chain plates of the chain. The two ends of the parking platform are hinged to the corresponding suspension plates through hinge shafts, and the parking platform can be driven to rise and fall by the rotation of the chain. The guide device is arranged on the door frame at one end of the parking platform and can guide the parking platform when it moves.

[0028] It should be noted that the garage frame is the basic structure of the entire multi-story garage, including two symmetrically vertically arranged gantries. The gantries provide support and guidance to ensure the stability and reliability of the lifting device and parking platform. The gantries can be connected by reinforcing rods to ensure the rigidity and stability of the overall structure; the lifting device is set on the garage frame and is responsible for lifting or lowering the parking platform to different positions. The parking platform is a platform for parking vehicles. Both ends are hinged to the suspension plate of the chain through a hinged shaft, and the rotation of the chain drives the lifting and lowering of the parking platform.

[0029] Preferably, the parking platform includes a load-bearing plate, a side baffle and a rear baffle, the side baffles are vertically arranged on both sides of the load-bearing plate, and the two ends of the rear baffle are arranged on the side baffles across the load-bearing plate; the guide device includes a sliding column and a guide rail, the sliding column is arranged at one end of the parking platform, the guide rail is fixedly installed on the door frame, and the parking platform can be guided by the cooperation of the sliding column and the guide rail.

[0030] It should be noted that the load-bearing plate is the main component of the parking platform, which directly bears the weight of the vehicle and is usually made of high-strength material to ensure sufficient load-bearing capacity; the side fenders are vertically arranged on both sides of the load-bearing plate, mainly used to prevent the vehicle from skidding during the movement of the parking platform and increase safety; the rear baffle is arranged across the load-bearing plate on the side fenders, and its main function is to prevent the vehicle from sliding backward when the parking platform is raised or lowered, ensuring that the vehicle is safely parked on the platform, and through the cooperation of the sliding column and the guide rail, it can ensure that the parking platform moves along the predetermined path during the lifting and lowering process, avoiding lateral deviation or tilting, and improving the positioning accuracy of the parking platform; the sliding column can be a metal column with a certain length, which can slide up and down along the guide rail. The surface of the sliding column should be smooth to reduce friction with the guide rail to ensure smooth movement of the parking platform, and the diameter of the sliding column should be slightly smaller than the inner diameter of the guide rail to ensure that the sliding column can slide freely in the guide rail but not loose.

[0032] The utility model provides a lifting device for a stereoscopic parking garage, which significantly reduces the weight of the sprocket, reduces material costs, simplifies the connection method between the sprocket and the drive device, and reduces the use of additional gears, thereby further reducing production costs and maintenance costs. The lightweight design of the hollow sprocket not only reduces the inertia during starting and stopping, but also improves the response speed and control accuracy of the system. Especially in the case of rapid start and emergency stop, the system response is more sensitive and safety is improved. At the same time, the design of the supporting wheel reduces friction, makes the sprocket easier to rotate, and improves the efficiency and stability of the entire system.

The transmission device 3 is arranged on the garage frame 1 between the driven sprocket 41 and the driving sprocket 42, and the transmission gear 32 can be engaged with the driving sprocket 42 for transmission.

[0048] The pitch of the chain 6 is twice the pitch of the driving sprocket 42 .

[0049] The tooth pitch of the driven sprocket 41 is the same as the pitch of the chain 6 .

[0050] The supporting wheel 5 of the driving sprocket 42 is fixed to the lower end of the garage frame 1 through the fixing frame 12, and the supporting wheel 5 of the driven sprocket 41 is set at the upper end of the garage frame 1 through the adjusting frame 13, and the adjusting frame 13 is adjustably set on the garage frame 1 through the adjusting device 7.

[0051] The adjusting device 7 is an adjusting screw 71 , which passes through the crossbeam at the top of the garage frame 1 and is connected to the corresponding adjusting connection. The spacing between the driving sprocket 42 and the driven sprocket 41 can be adjusted by rotating the adjusting screw 71 .

[0052] The fixing frame 12 and the adjusting frame 13 are both square frames, and there are eight supporting wheels 5 , which are evenly distributed in pairs on the four sides of the square frame.

[0053] The transmission shaft 31 is provided with a driven gear 33 , which is connected to the driving device 2 via a transmission chain, and a transmission ratio between the driven gear 33 and the driving device 2 is 1:3.

The same ensures perfect engagement between the chain 6 and the driven sprocket 41, reducing impact and wear during the transmission process; the design of the supporting wheel 5 helps to reduce the friction between the chain 6 and the garage frame 1, making the sprocket easier to rotate, and improving the efficiency of the entire system; the adjusting screw 71 passes through the crossbeam at the top of the garage frame 1 and is connected to the adjusting frame 13. By rotating the adjusting screw 71, the distance between the driven sprocket 41 and the driving sprocket 42 can be adjusted, thereby ensuring that the chain 6 always maintains appropriate tension and avoids tooth jumping and wear caused by the chain 6 being too loose or too tight.

[0056] When in use, first, fix the garage frame 1 in a suitable position to ensure the stability and verticality of the frame; install the driving device 2 and the transmission device 3, and ensure that the driving device 2 and the transmission shaft 31 of the transmission device 3 are correctly connected; assemble the supporting wheel 5 to the corresponding fixing frame 12 and the adjusting frame 13, and install the fixing frame 12 and the adjusting frame 13 on the garage frame 1, then respectively put the driving sprocket 42 and the driven sprocket 41 on the supporting wheel 5 of the fixing frame 12 and the adjusting frame 13, and make the driving sprocket 42 mesh with the transmission gear 32 of the transmission device 3 , install the adjusting device 7, ensure that the adjusting screw 71 can rotate freely and adjust the position of the driven sprocket 41; then put the chain 6 on the corresponding driving sprocket 42 and the driven sprocket 41; after the installation is completed, manually rotate the driving device 2, check whether the transmission device 3, the hollow sprocket 4 and the chain 6 are operating normally, ensure that there is no jamming or abnormal sound, adjust the adjusting screw 71 to keep the chain 6 at an appropriate tension to avoid being too loose or too tight, and finally start the driving device 2, observe the operation of the lifting device, and ensure that the lifting process is smooth and without abnormalities.

[0057] Example 2

[0058] like Figure 6 and Figure 7 As shown, a three-dimensional car park of this embodiment includes: the lifting device described in the first embodiment, a car park frame 1, a parking platform 8 and a guide device 9;

[0059] The lifting device is arranged on the garage frame 1, and the garage frame 1 includes two symmetrically vertically arranged door frames 11. Suspension plates 61 are provided at intervals on the outer link plates of the chain 6. The two ends of the parking platform 8 are hinged to the corresponding suspension plates 61 through hinge shafts, and the parking platform 8 can be driven to rise and fall by the rotation of the chain 6. The guide device 9 is arranged on the door frame 11 at one end of the parking platform 8, and can guide the parking platform 8 when it moves.

[0060] The parking platform 8 includes a load-bearing plate 81, a side baffle 82 and a rear baffle 83. The side baffle 82 is vertically arranged on both sides of the load-bearing plate 81, and the two ends of the rear baffle 83 are arranged on the side baffle 82 across the load-bearing plate 81; the guide device 9 includes a slide column 91 and a guide rail 92. The slide column 91 is arranged at one end of the parking platform 8, and the guide rail 92 is fixedly installed on the door frame 11, and the parking platform 8 can be guided by the cooperation of the slide column 91 and the guide rail 92.

[0061] The working principle and usage method of a stereo garage of this embodiment are as follows:

[0062] The present embodiment provides a three-dimensional parking garage, in which the parking platform 8 is a platform for parking vehicles, and includes a load-bearing plate 81, side baffles 82 and a rear baffle 83; the load-bearing plate 81 is the main component of the parking platform 8, directly bearing the weight of the vehicle, and is usually made of high-strength material to ensure sufficient load-bearing capacity; the side baffles 82 are vertically arranged on both sides of the load-bearing plate 81, mainly used to prevent the vehicle from sliding sideways during the movement of the parking platform 8, thereby increasing safety; the two ends of the rear baffle 83 are arranged on the side baffles 82 across the load-bearing plate 81, and their main function is to prevent the vehicle from sliding backward when the parking platform 8 is raised or lowered, thereby ensuring that the vehicle is safely parked on the platform; the guide device 9 includes a slide column 91 and Guide rail 92; the slide column 91 is set at one end of the parking platform 8, and the guide rail 92 is fixedly installed on the garage frame 1; the parking platform 8 cooperates with the guide rail 92 through the slide column 91 to ensure that it moves along the predetermined path during the lifting and lowering process, avoids lateral deviation or tilt, and improves the positioning accuracy of the parking platform 8; the slide column 91 can be a metal column with a certain length, which can slide up and down along the guide rail 92. The surface of the slide column 91 should be smooth to reduce the friction between the guide rail 92 and ensure the smooth movement of the parking platform 8, and the diameter of the slide column 91 should be slightly smaller than the inner diameter of the guide rail 92 to ensure that the slide column 91 can slide freely in the guide rail 92 but not loose.

[0063] During use, when the user needs to park the vehicle in the multi-story parking garage, first, the operator or automatic control system will start the driving device 2, and the driving device 2 will transmit power to the transmission shaft 31 through the transmission chain. The transmission gears 32 at both ends of the transmission shaft 31 are engaged with the hollow sprocket 4, driving the hollow sprocket 4 to rotate. The rotation of the hollow sprocket 4 is transmitted to the parking platform 8 through the chain 6, so that the parking platform 8 rises or falls to the ground floor following the rotation of the chain 6; when the parking platform 8 is lowered to the ground floor, the user can drive the vehicle into the parking platform 8; the load-bearing plate 81 of the parking platform 8 is designed to bear the weight of the vehicle, while the side baffles 82 and the rear baffle 83 effectively prevent the vehicle from accidentally sliding during parking, ensuring the safety of the vehicle; once the vehicle stops, the operator or the automatic control system starts the driving device 2 again, and lifts the parking platform 8 to the predetermined parking space according to the preset program. During this process, the guide device 9 (i.e., the cooperation between the slide column 91 and the guide rail 92) ensures the precise movement of the parking platform 8, avoids deviation or tilt due to external factors, and thus ensures the safety and smoothness of the lifting process; when the car needs to be picked up, the operation process is the opposite of parking, that is, the parking platform 8 is first lowered from a high position to the ground floor, and then the user drives the vehicle out. The whole process is highly automated, which greatly improves parking efficiency and user experience.
