Description

Technical Field

[0001] This utility model relates to parking equipment, specifically to a cantilevered simple lifting three-dimensional parking device. Background Technology

[0002] Mechanical automated parking systems, as a highly efficient space-utilizing parking solution, are gradually becoming an important part of urban parking facilities. Currently, the most common types of mechanical automated parking systems on the market include horizontal moving systems, vertical lifting systems, and lane-stacking systems, which alleviate parking pressure to some extent.

[0003] Vertical lift parking systems typically employ a four-column structure. While this design enables vertical lifting and parking of vehicles, it also presents several drawbacks. Firstly, the four-column structure increases overall equipment cost, requiring more materials and presenting greater processing and installation difficulties. Furthermore, the transmission and control systems of a four-column structure are more complex, increasing the failure rate and maintenance complexity, resulting in higher operating costs. However, reducing the number of columns introduces the problem of vehicle tilting. Existing technology typically uses balance chains to address this issue. Specifically, one end of each of two balance chains is fixed to the top plate of two columns, while the other end passes through a chain tube at the rear of the vehicle platform, exiting from under a pulley inside the chain tube. The two remaining ends of the balance chains engage with both ends of a balance shaft, which is then fixed to a bottom bracket. The balance shaft is fixed to the rear of the chain tube. However, balance chains have the following drawbacks: during vehicle lifting, the tension and position of the balance chains require precise adjustment to ensure the vehicle platform remains level. Improper adjustment can lead to vehicle tilting, affecting parking and retrieval.

[0004] In summary, existing four-column automated parking systems have significant shortcomings in terms of maintenance costs and structural complexity. While reducing the number of columns and using a balance chain requires high precision in the tension and position adjustment of the balance chain, making maintenance difficult and limiting its practical application, a more efficient, stable, and cost-effective automated parking system is urgently needed to address these issues.

The lifting assembly is slidably connected to the support assembly and fixedly connected to the car carrier plate. The power drive assembly drives the lifting assembly to slide along the support assembly, thereby raising and lowering the car carrier plate. The support assembly in this utility model only has a first column and a second column.

This structure effectively solves the problem of the other side of the vehicle platform tilting. When the other side of the vehicle platform tilts downwards due to excessive force, the lower guide wheels on the other side of the support plate provide counter-support force because the number of guide wheels on the lower part is greater than the number of guide wheels on the upper part.

The two fixing plates 61 are respectively fixed to the corresponding sides of the vehicle platform 10, realizing the fixed connection between the two lifting guides 6 and the vehicle platform 10.

[0060] The chain guide wheel 65 is located at the bottom of the support plate 62, and its central axis is parallel to the fixed plate 61. It is used to guide and support the chain 7.

[0061] like Figure 5 As shown, the power drive assembly 8 includes a motor 81 and a sprocket 82; the motor 81 is mounted on the top of the first column 2, and the sprocket 82 is sleeved on the output shaft of the motor 81 for meshing with the chain 7.

[0062] One end of the chain 7 is located on the outer side of the first column 2 and connected to the counterweight 66; the other end of the chain 7 passes sequentially around the top of the first column 2, the sprocket 82 of the power drive assembly 8, the corresponding chain guide wheel 65 mounted on the first column 2, then passes through the bottom surface of the vehicle platform 10, then passes around the corresponding chain guide wheel 65 mounted on the second column 3, and finally is fixedly connected to the lifting bolt 31. The lifting bolt 31 is fixedly installed on the top of the second column 3.

[0063] The fall arrestor includes an upper limit switch 91 and a lower limit switch 92 installed on the first column 2, and two fall arresters 93 installed on the first column 2 and the second column 3 respectively;

[0064] An upper limit switch 91 is located at the upper side of the first column 2, and a lower limit switch 92 is located at the lower side of the first column 2. A fall arrestor 93 located on the first column 2 is positioned between the upper limit switch 91 and the lower limit switch 92, and is close to the upper end of the first column 2. A fall arrestor 93 located on the second column 3 is positioned at the same height as another fall arrestor 93; both fall arrestors 93 are electrically connected to the upper limit switch 91 and the lower limit switch 92. Both the upper limit switch 91 and the lower limit switch 92 include a base, a shift fork, and a trigger switch; the base is connected to the first column 2; one end of the shift fork is installed inside the base, and the other end extends towards the vehicle platform 10, used to actuate the trigger switch when the vehicle platform 10 reaches its highest and lowest positions.

[0065] The fall arrestor 93 includes a housing, a hook, and a telescopic assembly; the housing is mounted on the first column 2 or the second column 3, and a fall arrestor hole is provided on the side of the housing facing the vehicle platform 10; the telescopic assembly is disposed inside the housing and connected to the hook, and is used to control the hook to extend out of the fall arrestor hole to provide a buffer force to the vehicle platform 10 when the upper limit switch 91 is triggered, or to control the hook to retract into the fall arrestor hole when the lower limit switch 92 is triggered, so as to allow the vehicle platform 10 to avoid the upward passage.

[0066] like Figure 7 As shown, the working process is as follows: The power drive component 8 is driven by a 2:1 winding method. After the motor 81 starts, it drives the chain 7 through the sprocket 82. The motor 81 drives the chain 7 to move from the first column 2 to the second column 3. The counterweight 66 moves from bottom to top along the first column 2, and the guide wheel 64 moves from top to bottom along the lifting guide rail 5. The two lifting guide components 6 drive the car platform 10 to descend. After the car platform 10 reaches the lowest position, the lower limit switch 92 is activated. The lower limit switch 92 triggers the hook in the fall arrestor 93 to retract the fall arrestor hole, so as to avoid obstructing the rise of the car platform 10. After a vehicle drives into the car carrier 10 and stops, the motor 81 drives the chain 7 from the second column 3 towards the first column 2. The counterweight 66 moves from top to bottom along the first column 2, and the guide wheel 64 moves from bottom to top along the lifting guide rail 5. The two lifting guides 6 lift the car carrier 10 to its highest position. After the car carrier 10 reaches its lowest position, the upper limit switch 91 is activated. The upper limit switch 91 triggers the hook in the fall arrestor 93 to retract into the fall arrestor hole, providing fall protection for the car carrier 10. The second vehicle drives into the space below the car carrier 10 and stops between the two parallel fixed rods 11.
