Description

Technical Field

[0001] This utility model relates to the field of automated parking system technology, and in particular to a limiting device. Background Technology

[0002] With the increasing scarcity of urban land resources, multi-level parking garages have been widely adopted due to their high space utilization. In multi-level parking garages, the precise and stable positioning of the vehicle platform or rack is crucial for the safe storage and retrieval of vehicles. After the vehicle platform or rack is transported to the target parking space via a lift, it must be effectively limited to prevent accidental movement or slippage during subsequent operations. Therefore, a limiting device is needed to prevent the vehicle platform or rack from sliding off the parking space track and falling.

[0003] In the existing technology, there are many types of limit devices used in automated parking garages. Some devices use power components such as electric push rods, electromagnets, or small hydraulic cylinders to directly drive the limit pins or blocks, but these require additional power or hydraulic power sources and corresponding control systems, resulting in complex structures, increased manufacturing costs, and maintenance difficulties. In harsh environments such as damp and dusty garages, the reliability of electrical or hydraulic components may be affected, posing potential malfunctions. On the other hand, some purely mechanical limit devices, while avoiding reliance on external power, have relatively cumbersome structures, are not convenient to operate, and have high processing costs and a high risk of jamming due to their complex mechanical structures. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a limiting device to more accurately resolve the issues of complex structure, high processing and maintenance costs, and high risk of jamming in existing multi-level parking garage limiting devices.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a limiting device, including a mounting frame with a U-shaped cross-section. The mounting frame has multiple sets of mounting holes on its surface and a limiting component is provided on the inner wall of the mounting frame. The limiting component is used to limit and fix the vehicle platform and the comb frame.

[0007] Furthermore, the limiting component includes a fixing plate and a fixing frame. The fixing plate is fixedly connected to the inner wall edge of the mounting frame, and the fixing frame is fixedly connected to the top of the mounting frame. A first bearing is installed on the side wall of the mounting frame by bolts, and a push rod is slidably installed in the first bearing and the mounting frame.

[0008] Furthermore, the cross-section of the fixing frame is Z-shaped, and the push rod is cylindrical.

[0009] Furthermore, a limiting plate is sleeved on the outside of the push rod, and a spring is sleeved on the outside of the push rod. The spring is located between the first bearing and the limiting plate, and a first limiting pin is screwed into the end of the push rod.

[0010] Furthermore, a first connecting rod is provided on the inner wall of the fixing plate, and a first sliding opening is provided on one end surface of the first connecting rod. A second connecting rod is provided on the outer wall of the fixing plate, and a second sliding opening is provided on one end surface of the second connecting rod.

[0011] Furthermore, the first connecting rod and the second connecting rod are fixedly connected together by a rotating shaft, the first sliding opening is correspondingly set with the first limiting pin, and both the first connecting rod and the second connecting rod are inclined.

[0012] Furthermore, a second bearing is bolted to the top of the fixed frame, and a limit rod is slidably installed inside the fixed frame. A second limit pin is threadedly installed at the bottom end of the limit rod.

[0013] Furthermore, the second limiting pin is correspondingly provided with the second sliding opening, and the limiting rod has a cylindrical structure.

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0024] Please refer to Figures 1-5 This utility model proposes a limiting device, including a mounting frame 1. The mounting frame 1 has a U-shaped cross-section. Multiple sets of mounting holes 2 are opened on the surface of the mounting frame 1 for mounting and fixing the mounting frame 1. A limiting component is provided on the inner wall of the mounting frame 1. The limiting component is used to limit and fix the vehicle platform and the comb frame. By using fixing bolts to pass through the mounting holes 2 and fix them, the mounting frame 1 can be connected and fixed together with the three-dimensional garage fixing frame 4.

[0025] The limiting assembly includes a fixing plate 3 and a fixing frame 4. The fixing plate 3 is fixedly connected to the inner wall edge of the mounting frame 1 by welding, and is used to limit the rotation of the first connecting rod 10 and the second connecting rod 12. The fixing frame 4 is fixedly connected to the top of the mounting frame 1. A first bearing 5 is bolted to the side wall of the mounting frame 1 to limit the push rod 6 and ensure the horizontal movement of the push rod 6. The push rod 6 is slidably installed in the first bearing 5 and the mounting frame 1 to push the rotation of the first connecting rod 10 and the second connecting rod 12. The fixing frame 4 has a Z-shaped cross-section, and the push rod 6 has a cylindrical structure. A limiting plate 7 is sleeved on the outside of the push rod 6 to limit the spring 8. An external spring 8 is installed to ensure the reset of the push rod 6 and the limiting rod 15. The spring 8 is located between the first bearing 5 and the limiting plate 7. A first limiting pin 9 is screwed into the end of the push rod 6. A first connecting rod 10 is limited on the inner wall of the fixing plate 3 to drive the second connecting rod 12 to rotate. A first sliding opening 11 is opened on one end surface of the first connecting rod 10. A second connecting rod 12 is limited on the outer wall of the fixing plate 3 to drive the limiting rod 15 to move. A second sliding opening 13 is opened on one end surface of the second connecting rod 12. The first connecting rod 10 and the second connecting rod 12 are fixedly connected together by a rotating shaft. The first sliding opening 11 is correspondingly set with the first limiting pin 9. Both the first connecting rod 10 and the second connecting rod 12 are inclined. A second bearing 14 is bolted to the top of the fixed frame 4 to limit the movement of the limiting rod 15, ensuring its vertical movement. The second bearing 14 slides through the fixed frame 4 to install the limiting rod 15, which limits the movement of the vehicle platform or comb frame. A second limiting pin 16 is threaded into the bottom end of the limiting rod 15. The second limiting pin 16 corresponds to the second sliding opening 13. The limiting rod 15 has a cylindrical structure. When the vehicle platform or comb frame is raised or lowered, and the vehicle platform or comb frame is raised or lowered to the designated parking position by the lift, the push rod 6 is pushed by the pusher device in the tray. The movement of the push rod 6 causes the limiting piece 7 and the first limiting pin 9 to move laterally. The movement of the limiting piece 7 causes the spring 8 to compress. With the cooperation of the sliding opening 11, the movement of the first limiting pin 9 causes the first connecting rod 10 and the second connecting rod 12 to rotate. Under the limitation of the second sliding opening 13 and the second bearing 14, the rotation of the second connecting rod 12 causes the second limiting pin 16 to move downward. The downward movement of the second limiting pin 16 drives the limiting rod 15 to retract, thereby opening the limiting device. At this time, the car platform or comb frame can slide out of the parking space track. After the lifting and lowering of the car platform or comb frame is completed, the thrust device removes the thrust. Under the action of the spring 8, the push rod 6 drives the first connecting rod 10 and the second connecting rod 12 to reset. The reset of the second connecting rod 12 drives the limiting rod 15 to reset. The limiting rod 15 extends to block the car platform or comb frame, preventing the car platform or comb frame from sliding out of the parking space track and falling, thus locking the car platform or comb frame.It features a simple structure, fast response, stability, reliability, and low cost.

[0026] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
