Abstract
Description
Technical Field
[0001] This utility model relates to the field of fall prevention devices, and in particular to a garage fall prevention device with anti-sway function. Background Technology
[0002] Mechanical automated parking systems can improve parking efficiency, but they also pose safety risks due to malfunctioning fall arrestors. During the descent of the vehicle platform, some fall arrestors may not fully open on one side, causing the platform to become stuck at a corner or edge of the vehicle, potentially leading to a rollover. Accidents can also occur during the lifting phase. When some fall arrestors or those on one side are not fully open, the side beams during the ascent may mechanically interfere with the partially opened arrestors, causing overload on the lifting mechanism. This can damage critical components such as chains, wire ropes, lifting shafts, and bearing housings, ultimately leading to a vehicle falling.
[0003] Existing fall protection devices have the following main shortcomings:
[0004] 1. Most lifting equipment is equipped with anti-fall devices, and its platform side beams use a U-shaped lifting ring design. However, in actual use, these U-shaped lifting rings are easily deformed and bent due to vehicle running over them or people stepping on them, thus losing their normal function and creating a safety hazard. Some designs also use elongated holes in the side beams. This not only weakens the structural strength of the side beams but also significantly reduces the rated load-bearing capacity of the platform.
[0005] 2. In multi-level lifting and traversing parking systems, since each intermediate level is equipped with a traversing frame, an anti-sway device for the vehicle platform is required when the intermediate level's traversing frame shifts left or right. This device typically uses a positioning rod embedded in a pre-drilled hole in the side beam, or applies lateral compressive force through a guide plate to constrain the displacement of the vehicle platform, thereby effectively suppressing the swaying of the vehicle platform. The structure of the anti-sway device system installed in conjunction with this system is relatively complex. Utility Model Content
[0006] The purpose of this invention is to address the problems existing in the background technology by proposing a garage anti-fall device with anti-sway function, which can effectively prevent the vehicle platform from falling and achieve the anti-sway function through a simple structure.
[0007] The technical solution of this utility model is a garage anti-fall device with anti-sway function, including an anti-fall frame, a lifting assembly, and a limiting assembly; a second baffle is vertically installed on the anti-fall frame; the lifting assembly includes a chain, an anti-fall hook, and a vehicle platform connecting seat connected from top to bottom, and the anti-fall hook has a slot on the side away from the second baffle; the limiting assembly includes a safety card, an electromagnet, and a connecting rod, the safety card is rotatably installed on the anti-fall frame and is inclined upwards, the electromagnet is installed on the anti-fall frame, the telescopic end of the electromagnet is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the safety card, when the electromagnet is energized, the top of the safety card is pulled out from the slot through the connecting rod, and when the electromagnet is de-energized, the top of the safety card rotates to the inside of the slot.
[0008] Preferably, the center of gravity of the insurance card is located on the side of the insurance card's rotation axis facing the fall arrestor hook.
[0009] Preferably, the fall arrestor is detachably mounted on a mounting base, and the electromagnet is detachably mounted on the mounting base.
[0010] Preferably, the fall arrestor is equipped with a detection switch, which has a detection head, and the safety catch has a protrusion that pushes the detection head.
[0011] Preferably, a baffle is vertically installed on the fall arrestor, the baffle is located between the baffle and the electromagnet, the baffle has a channel for the safety card to pass through, and a lifting channel for the fall arrestor hook and chain to pass through is formed between the baffle and the baffle.

[0013] Preferably, the bottom of baffle one is inclined away from baffle two, and the bottom of baffle two is inclined away from baffle one.
[0014] Compared with existing technologies, this utility model has the following beneficial technical effects: It has a strong load-bearing capacity, effectively preventing the vehicle platform from falling, and achieves anti-sway function through a simple structure. When raising or lowering the vehicle platform, the safety latch opens, and the lifting channel between baffle one and baffle two is unobstructed. Baffle one and baffle two can also provide anti-sway limiting. After the vehicle platform rises to its position, the top of the safety latch is rotated to the inside of the anti-fall hook's slot. The anti-fall hook will be blocked by the safety latch and will not fall, providing good anti-fall performance and effectively preventing vehicle falling accidents. Furthermore, the anti-fall and anti-sway structures in this device are compactly designed and occupy little space. Attached Figure Description

[0018] Example 1
[0019] like Figure 1 and Figure 2 As shown in the figure, the garage anti-fall device with anti-sway function proposed in this embodiment includes an anti-fall frame 1, a lifting component and a limiting component.
[0020] The fall arrestor 1 is installed at the bottom of the longitudinal beam structure 2, and a first baffle 9 and a second baffle 10 are vertically installed on the fall arrestor 1. When both baffles 9 and 10 are installed simultaneously, the lifting assembly can be anti-sway limited from both sides. When only baffle 10 is installed, the lifting assembly can be anti-sway limited from one side, but the anti-sway effect is not as good as when both baffles 9 and 10 are installed simultaneously. A lifting channel is formed between baffles 9 and 10 for the fall arrestor hook 11 and chain 12 to pass through. The length of baffle 9 is greater than the length of baffle 10, and the bottom height of baffle 9 is lower than the bottom height of baffle 10. Baffle 9 has a better limiting effect on that side and can prevent the lifting assembly from swinging excessively to the right.
[0021] The lifting assembly includes a chain 12, a fall arrestor hook 11, and a vehicle platform connecting seat 8 connected sequentially from top to bottom. The fall arrestor hook 11 has a slot on the side facing away from the second baffle 10. The bottom of the first baffle 9 is inclined away from the second baffle 10, and the bottom of the second baffle 10 is also inclined away from the first baffle 9, which has a certain guiding effect on the fall arrestor hook 11, allowing the fall arrestor hook 11 to smoothly enter the inner side of the lifting channel when it moves upward.
[0022] like Figure 1 As shown, the limiting assembly includes a safety catch 3, an electromagnet 6, and a connecting rod 7. The safety catch 3 is rotatably mounted on the fall arrestor 1 and is tilted upwards. The electromagnet 6 is mounted on the fall arrestor 1. Specifically, the fall arrestor 1 has a detachable mounting base 5. The mounting position of the mounting base 5 is determined according to actual needs and is installed by bolts. The electromagnet 6 is detachably mounted on the mounting base 5 and is also connected by bolts. The position of the electromagnet 6 can be determined as needed.
[0023] The telescopic end of electromagnet 6 is rotatably connected to one end of connecting rod 7, and the other end of connecting rod 7 is rotatably connected to safety clip 3. When electromagnet 6 is energized, it retracts, pulling connecting rod 7. This pulls the top of safety clip 3 out of the slot. At this time, the garage control system's lifting motor starts to rise, driving chain 12 to pull anti-fall hook 11, thereby raising the vehicle platform connecting seat 8, and subsequently raising the vehicle platform installed on the vehicle platform connecting seat 8. Safety clip 3 does not interfere with the rising of anti-fall hook 11. The center of gravity of safety clip 3 is located on the side of the rotation axis of safety clip 3 facing anti-fall hook 11. After the vehicle platform has lifted the vehicle into position, electromagnet 6 is de-energized, and safety clip 3 rotates counterclockwise due to its own weight. The top of safety clip 3 rotates to the inside of the slot, located below the top of the slot. At this time, in the event of a fall, safety clip 3 can block anti-fall hook 11, ensuring that anti-fall hook 11 will not fall.
[0024] like Figure 1 As shown, baffle 9 is located between baffle 10 and electromagnet 6, and baffle 9 has a channel for safety card 3 to pass through. When the fall arrestor hook 11 pulls down the safety card 3 through the slot, baffle 9 and baffle 10 can limit the swing range of the fall arrestor hook 11 and chain 12 to prevent excessive swing. At the same time, the bottom end of the channel of baffle 9 can further limit the safety card 3, further enhancing the fall protection effect of the safety card 3 on the fall arrestor hook 11.
[0025] This embodiment boasts strong load-bearing capacity, effectively preventing the vehicle platform from falling and achieving anti-sway function through a simple structure. During the raising and lowering of the vehicle platform, the safety latch 3 is turned open, ensuring unobstructed access between baffle 9 and baffle 10. Baffle 9 and baffle 10 also provide anti-sway limiting. The anti-fall hook 11 and chain 12 can move smoothly up and down. After the vehicle platform reaches its designated position, the top of the safety latch 3 is rotated to the inside of the slot of the anti-fall hook 11. In the event of a vehicle falling, the anti-fall hook 11 will be blocked by the safety latch 3, preventing it from falling. This provides excellent anti-fall performance and effectively avoids vehicle falling accidents. Compared to traditional solutions that require anti-fall U-shaped lifting rings or slotted lifting seats on the side beams of the vehicle platform, along with a complete set of anti-sway rod positioning sleeves, this device achieves superior anti-sway and anti-fall performance solely through its structural characteristics. Furthermore, the anti-fall and anti-sway structures in this device are compactly designed, occupying minimal space.
[0026] Example 2
[0027] like Figure 1 and Figure 2As shown in this embodiment, a garage fall arrestor with anti-sway function is proposed. Compared to Embodiment 1, in this embodiment, a detection switch 4 is installed on the fall arrestor frame 1. The detection switch 4 has a detection head, and the safety catch 3 has a protrusion that pushes the detection head. The detection switch 4 is used to detect the position of the safety catch 3. When the electromagnet 6 is energized and retracts, it drives the connecting rod 7 to pull the safety catch 3. The safety catch 3 pushes down the detection head through the protrusion. At this time, the detection switch 4 detects that the safety catch 3 is in the open state, the lifting channel is unobstructed, the garage control system's lifting motor starts to rise, and the vehicle is raised. Similarly, the vehicle can be lowered. After the electromagnet 6 is de-energized, the top of the safety catch 3 rotates to the inside of the slot, the protrusion rotates counterclockwise, and no longer presses down on the detection head of the detection switch 4. At this time, the detection switch 4 detects that the safety catch 3 is in the fall arrestor engaged state, and the safety catch 3 can prevent the vehicle from falling.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
