Description

Technical Field

[0001] The invention relates to the field of stereo garages, and in particular to a circulating lifting type stereo garage. Background Art

[0002] With the development of vehicle parking garages, in order to facilitate the transportation of vehicles to different levels for storage and retrieval, special lifting equipment for vehicles is often needed, which can not only replace the ramps for vehicles to enter and exit the garage, but also greatly save space and improve the utilization rate of the garage. Parking difficulties and traffic congestion are also one of the concerns affecting the development of the automobile industry. The construction of a small-footprint, highly intelligent three-dimensional garage is also 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 bearing frame, a lifting chain and a guide rail; the driving frame and the guide frame are frame structures welded by 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 constitutes a load-bearing main body; a closed guide rail is respectively arranged in the vertical frame of the driving frame and the guide frame, a lifting chain is arranged on the closed guide rail, 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 plates are evenly distributed on the lifting chain, a plurality of bearing frames are arranged in parallel and horizontally between the corresponding two lifting chains, and the hinge shafts on the crossbeams on both sides of each bearing frame are hinged with the corresponding lifting chain plates; although the stereoscopic parking garage can effectively reduce the ground occupied area and improve the parking efficiency; the following problems still exist: 1. The lifting device of the existing three-dimensional parking garage adopts a sprocket formed by a combination of a paddle wheel and a gear to mesh with the chain for transmission. However, most of the paddle wheels and gears are solid structures with high production costs. In addition, due to the heavy weight of the solid sprocket, it not only increases the burden of 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, which accelerates the aging and damage of these components and affects the response speed and control accuracy of the equipment.

[0004] 2. The guide devices of existing stereo garages all use guide rails that surround the frame. When the number of parking spaces needs to be increased or the parking space layout needs to be adjusted, the disassembly and assembly of the original guide rails greatly affects work efficiency; and the vehicle loading plate is subjected to large lateral forces during vertical circulation motion, especially when the vehicle loading plate moves up and down. If there is an uneven load or the center of gravity of the vehicle is offset, it is easy to cause the vehicle loading plate to tilt, increasing the risk of system instability. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a circulating lifting type three-dimensional parking garage, which improves the safety, stability and space utilization of the garage operation by adopting hollow sprockets, limit devices and arc guide rails, while reducing energy consumption and maintenance costs.

[0006] The technical solution adopted by the present invention to solve its technical problem is: Provided is a circulating lifting type stereoscopic car park, comprising: two symmetrically arranged door frames, a vehicle loading platform, a driving device, a hollow sprocket, a chain, a transmission device, an arc guide rail and a limit device; The hollow sprockets are respectively arranged at the upper and lower ends of the two door frames, and are connected to the driving device through a transmission device. The chain is meshed on the corresponding hollow sprocket. The arc guide rails are respectively arranged at the corners of the upper and lower ends of the door frames on one side. The two ends of the vehicle loading platform are hinged on the suspension plates corresponding to the chains through rotating shafts, and a guide column is provided on the cross beam close to one end of the arc guide rail corresponding to the arc guide rail. The guide column guides the vehicle loading platform by cooperating with the arc guide rail. The limit device includes a limit push rod and a limit groove. The limit push rod and the limit groove are respectively arranged on the upper and lower sides of the vehicle loading platform and are located on the same vertical axis line, and the limit push rod can be embedded in the corresponding limit groove when the vehicle loading platform is vertically lifted or lowered.

[0007] It should be noted that the hollow sprocket reduces the weight of the entire lifting system and reduces energy consumption. Since the hollow sprocket is lighter, the inertia during starting and stopping is reduced, and the pressure on the motor and other transmission components is reduced, thereby extending the life of the equipment and improving the response speed and control accuracy. The coordination of the arc guide rail and the limit device optimizes the guiding mechanism of the vehicle loading platform during vertical cyclic motion, reduces the influence of lateral force, especially in the case of uneven load or vehicle center of gravity offset, can better maintain the stability of the vehicle loading platform and reduce the risk of tilting; the limit groove can be a groove body opened on the vehicle loading mechanism (can be rectangular, circular or other suitable shapes, but it is necessary to ensure that the limit push rod can be smoothly inserted and clamped), or it can be a groove body enclosed by parts, ensuring that the vehicle loading platform can remain stable without the use of guide rails during the up and down movement, preventing accidental tilting or deviation from the track, and at the same time, when it is necessary to increase the number of parking spaces or adjust the parking space layout, it can be operated more simply to improve work efficiency.

[0008] Preferably, the hollow sprocket is arranged on the portal frame through at least four supporting wheels, the supporting wheels are evenly distributed in a circle at the upper and lower ends of the corresponding portal frame, and the hollow sprocket support sleeve is arranged on the outside of all the supporting wheels distributed in a circle.

[0009] It should be noted that the uniform distribution of the supporting rollers can ensure that the force exerted on the hollow sprocket is evenly dispersed to each supporting roller, avoiding the situation where a single supporting roller is subjected to excessive pressure and causes premature damage, thereby improving the stability and durability of the entire system. In addition, due to the existence of the supporting rollers, there is no direct contact between the hollow sprocket and the portal frame, but power is transmitted through the rolling of the supporting rollers, which reduces the friction between the two, not only reduces the wear rate, but also helps to reduce energy loss and reduce energy consumption.

[0010] Preferably, the door frame includes a door-shaped base, a lifting frame, a fixed frame and an adjusting frame. The lifting frame is coaxially arranged on the door-shaped base, the fixed frame is coaxially fixedly arranged at the lower end of the lifting frame, the adjusting frame is coaxially arranged at the upper end of the lifting frame and can be adjusted by an adjusting device, and the distance between the adjusting frame and the fixed frame can be adjusted by the adjusting device, and the supporting wheels are respectively and correspondingly arranged on the fixed frame and the adjusting frame.

[0011] It should be noted that the door-type base serves as the basic supporting structure of the entire multi-story garage, ensuring the overall stability and load-bearing capacity. The lifting frame is coaxially arranged on the door-type base, and is the main supporting part for the vertical movement of the vehicle-carrying platform. It provides a fixed installation position for the supporting wheel, ensuring the stability of the lower hollow sprocket. The adjusting frame: The adjusting device is coaxially arranged on the upper end of the lifting frame, and the distance between the lifting frame and the fixed frame can be adjusted by the adjusting device, so as to realize the tensioning of the chain and ensure that the chain maintains appropriate tension during operation.

[0012] Preferably, wheel grooves are opened at the upper and lower ends of the lifting frame corresponding to the sprockets, the fixed frame and the adjusting frame are correspondingly arranged in the middle of the wheel grooves, and chain grooves are opened on the vertical support rod in the middle corresponding to the chains. The chain grooves are connected to the wheel grooves and can guide the chains through the chain grooves.

[0013] It should be noted that wheel grooves are opened at the upper and lower ends of the lifting frame, and the fixed frame and the adjusting frame are located in the middle of the wheel grooves. They provide support for the supporting wheels so that the sprocket can be placed firmly and operate normally. The design of the chain groove enables the chain to move smoothly between the lifting frame, the fixed frame and the adjusting frame, reducing the lateral displacement of the chain and improving the stability and reliability of the entire system. The wheel groove and chain groove design not only optimizes the guidance and protection of the chain, but also enhances the structural stability and transmission efficiency of the entire multi-story parking garage.

[0014] Preferably, the adjusting device is an adjusting screw, one end of which passes through the upper cross beam of the adjusting frame and is connected to the adjusting frame, and the other end passes through the upper cross beam of the lifting frame and is arranged on the lifting frame, and the distance between the upper cross beam of the adjusting frame and the upper cross beam of the lifting frame can be controlled by rotating the adjusting screw.

[0015] It should be noted that adjustment by adjusting screw is a common mechanical adjustment method, which has a simple structure and is easy to manufacture and install. By rotating the adjusting screw, the distance between the adjusting frame and the lifting frame can be fine-tuned, thereby achieving the purpose of accurately controlling the chain tension. When the chain tension needs to be adjusted, only the adjusting screw needs to be rotated without disassembling other parts, which simplifies the maintenance process.

[0016] Preferably, the arc guide rail comprises an upper guide rail and a lower guide rail symmetrically arranged along the center line of the door frame width direction, and the upper guide rail is fixedly arranged at the upper end corner of the lifting frame through a guide rail frame; the lower guide rails are respectively arranged at the corners of the upper end of the door-shaped base.

[0017] It should be noted that the upper guide rail and the lower guide rail are symmetrically arranged along the center line of the portal frame width direction, ensuring that the vehicle loading platform can maintain balance when moving up and down, reducing the risk of deviation and tilting. The upper guide rail and the lower guide rail are arranged at the end corners of the lifting frame, so that the vehicle loading platform can smoothly transition during the conversion process from horizontal to vertical or from vertical to horizontal, reducing impact and vibration.

[0018] Preferably, the guide column includes a fixed plate, a sliding column and a limit column. The fixed plate is symmetrically and vertically arranged on the cross beam on one side above the vehicle loading platform, and the sliding column and the limit column are respectively arranged thereon. The upper guide rail and the lower guide rail both include an inner arc plate and an outer arc plate coaxially arranged on the door frame. The inner arc plate and the outer arc plate form a guide groove for the sliding column to slide therebetween, and the sliding column can be inserted into the corresponding guide groove and slide along the guide groove.

[0019] It should be noted that the fixed plate provides a stable installation foundation for the sliding column and the limit column, ensuring that their positions on the vehicle loading platform remain fixed. The sliding column can be inserted into the guide groove between the upper guide rail and the lower guide rail and slide along the guide groove. This can ensure that the vehicle loading platform maintains the correct path during vertical cyclic motion and reduce deviation and shaking; the limit column is used to prevent the vehicle loading platform from exceeding the predetermined range during movement, and plays a role of safety limit. When the vehicle loading platform reaches the limit position, the limit column will contact the corresponding guide groove, so that the vehicle loading platform continues to move along the correct path.

[0020] Preferably, the chain includes a plurality of inner chain plates, a plurality of outer chain plates and rollers, and adjacent inner chain plates and outer chain plates are connected by rollers. The suspension plates are evenly distributed on the outer chain plates and are integrally formed with the outer chain plates, and the pitch of the chain is at least twice the pitch of the hollow sprocket.

[0021] It should be noted that the suspension plates are evenly distributed on the outer link plates of the chain and are integrally formed with the outer link plates, which enhances the integrity of the structure, reduces the number of connection points, ensures that the vehicle-carrying platform can be firmly connected to the chain, and improves the stability and reliability of the system; the pitch of the chain is at least twice the pitch of the hollow sprocket, which means that the distance between each link point on the chain (i.e., the connection point between the link plates) is twice or more integer multiples of the pitch of the hollow sprocket. The larger pitch not only ensures a more stable engagement between the chain and the hollow sprocket, reduces the risk of tooth jumping and sliding, and improves transmission efficiency and control accuracy, but also reduces the vibration and noise of the chain during operation, thereby improving the user experience.

[0022] Preferably, the vehicle loading platform includes a base frame, a vehicle loading plate and a rotating shaft. The base frame is horizontally fixed and suspended on the rotating shaft by a suspension rod. The vehicle loading plate is symmetrically arranged on the base frame corresponding to the width between the wheels. Side guard plates are arranged on both sides of the base frame. A rear guard bar is arranged above one end of the base frame and across the base frame.

[0023] It should be noted that the chassis provides a solid foundation that can bear the weight of the vehicle and ensure that the vehicle-carrying platform remains level during vertical movement. The vehicle-carrying plate directly carries the vehicle, and its symmetrical setting ensures the balance of the vehicle when parked, reducing the risk of instability caused by center of gravity shift. The pivot is a key component connecting the vehicle-carrying platform and the chain. Through the pivot, the vehicle-carrying platform can be vertically lifted and lowered with the movement of the chain. At the same time, the design of the pivot enables the vehicle-carrying platform to smoothly enter or exit the parking space in a horizontal state; the side guard prevents the vehicle from sliding sideways during the lifting process, increasing the safety of the vehicle-carrying platform; the rear guard bar is used to prevent the vehicle from sliding on the vehicle-carrying platform, especially providing additional blocking when parking, to ensure that the vehicle does not move due to inertia during the lifting process.

[0024] Preferably, the transmission device includes a transmission shaft and a transmission gear, and the two ends of the transmission shaft are respectively arranged on the two door frames through bearing seats. The driving device is connected to the transmission shaft through a transmission chain, and the transmission gears are correspondingly arranged at the two ends of the transmission shaft and can be respectively connected to the hollow sprockets on the two door frames.

[0025] It should be noted that the drive shaft is the main component of power transmission, which evenly distributes the power of the drive motor to the hollow sprockets on the two gantries; the bearing seat provides stable support and reduces the friction and wear of the drive shaft; the transmission gear engages with the hollow sprocket to convert the rotational motion of the drive shaft into the linear motion of the chain, thereby driving the vehicle carrier platform to rise and fall vertically. The design of the transmission gear ensures the smoothness and precision of the transmission process.

[0026] Beneficial effects of the present invention: The present invention provides a circulating lifting type three-dimensional parking garage, which not only reduces the weight and energy consumption of the lifting system, but also improves the safety and stability of the garage operation by adopting designs such as hollow sprockets, arc-shaped guide rails and limit devices. By optimizing the guiding structure of the vehicle loading platform, a good balance state can be maintained even in the face of uneven loads or vehicle center of gravity offset, thereby reducing the risk of system failure. In addition, it helps to simplify the installation process and improve work efficiency, while reducing maintenance costs, providing users with a more efficient, reliable and economical parking solution.

[0043] The vehicle loading platform 2 includes a base frame 22, a vehicle loading plate 23 and a rotating shaft 21. The base frame 22 is horizontally fixed and suspended on the rotating shaft 21 through a suspension rod 24. The vehicle loading plate 23 is symmetrically arranged on the base frame 22 corresponding to the width between the wheels. Side guard plates are arranged on both sides of the base frame 22. A rear guard bar 25 is arranged above one end of the base frame 22 and across the base frame 22.

[0044] The transmission device 3 includes a transmission shaft 31 and a transmission gear 32. The two ends of the transmission shaft 31 are respectively arranged on the two door frames 1 through bearing seats. The driving device 4 is connected to the transmission shaft 31 through a transmission chain. The transmission gear 32 is correspondingly arranged at the two ends of the transmission shaft 31 and can be connected to the hollow sprockets 5 on the two door frames 1 respectively.

[0045] The working principle and use method of a circulating lifting type stereo garage of this embodiment: The embodiment provides a circulating lifting type three-dimensional parking garage, in which the driving motor is the power source of the entire system, and the power is transmitted to the transmission shaft 31 through the transmission chain. The transmission gear 32 is arranged at both ends of the transmission shaft 31 and meshes with the hollow sprocket 5. The hollow sprocket 5 is arranged at the upper and lower ends of the two door frames 1, and the chain 6 is meshed on the hollow sprocket 5. When the transmission shaft 31 rotates, the transmission gear 32 drives the hollow sprocket 5 to rotate, thereby driving the chain 6 to move; the suspension plates 64 are evenly distributed on the outer chain plates 62 of the chain 6 and are integrally formed with the outer chain plates 62. The vehicle loading platform 2 is hinged on the suspension plates 64 corresponding to the chain 6 through the rotating shaft 21, so that the vehicle loading platform 2 can move with the movement of the chain 6. The vehicle loading platform 2 is vertically lifted and lowered. The arc guide rails 7 are arranged at the upper and lower corners of the door frame 1 on one side to guide the vehicle loading platform 2 to move along the correct path. The guide column 9 is arranged on the cross beam of the vehicle loading platform 2 close to one end of the arc guide rail 7. The sliding column 92 on the guide column 9 is inserted into the guide groove 73 in the arc guide rail 7 to ensure that the vehicle loading platform 2 moves smoothly along the arc guide rail 7; the limiting device 8 includes a limiting top rod 81 and a limiting groove 82, which are respectively located on the upper and lower sides of the vehicle loading platform 2. When the vehicle loading platform 2 is vertically lifted and lowered, since there is no guide rail for guiding, the limiting top rod 81 is embedded in the corresponding limiting groove 82 to prevent the vehicle loading platform 2 from exceeding the predetermined range to ensure safety.

[0046] When in use, the user or the control system issues an instruction to store or retrieve the vehicle; the drive motor is started, and the power is transmitted to the hollow sprocket 5 through the transmission chain, the transmission shaft 31 and the transmission gear 32. The hollow sprocket 5 rotates, driving the chain 6 to move, and the hanging plate 64 on the chain 6 drags the vehicle loading platform 2 to move to the ground layer. After the vehicle enters the vehicle loading platform 2 and stops, the drive motor is started again, and the vehicle loading platform 2 and the vehicle are lifted upward through the chain 6. During the process of the vehicle loading platform 2 turning from the ground layer to the vertical lifting process, the guide column 9 cooperates with the arc guide rail 7 to ensure that the vehicle loading platform 2 moves stably along the specified path. When the vehicle loading platform 2 starts to lift vertically, the limiting top rod 81 of the limiting device 8 is embedded in the limiting groove 82 of the next vehicle loading platform 2 to prevent the vehicle loading platform 2 from shifting; similarly, when the user or the control system issues a vehicle retrieval instruction, the drive motor is started, and the vehicle loading platform 2 and the vehicle are lowered to the ground layer. After the vehicle leaves the vehicle loading platform 2, the system confirms that it is correct and then performs the next operation.
