Description

Technical Field

[0001] This utility model relates to the field of automated parking system technology, and in particular to a mechanical anti-fall safety device for automated parking systems. Background Technology

[0002] A multi-level parking garage is a type of equipment or building that uses mechanical structures to vertically or horizontally stack parking spaces on a limited area of ​​land in order to efficiently utilize land resources and increase parking capacity.

[0003] If there are people below the vehicle (such as the owner or maintenance personnel) when it falls, it can cause fatal injuries. Fall arrest devices can significantly reduce the falling speed through mechanical locking or buffering design, giving people time to escape. Therefore, fall arrest safety devices are necessary. Currently, fall arrest safety devices use electromagnets to attract and release the fall arrest hook, which requires multiple electromagnets. However, the increase in electrical components leads to more potential failure points. Electromagnets are sensitive to environmental humidity and temperature, and are prone to corrosion or short circuits in humid or high-temperature environments. Utility Model Content

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1: Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a mechanical anti-fall safety device for a three-dimensional parking garage, including a top plate 1, a support plate 2 provided below the top plate 1, four mounting components 3 provided at the four corners of the top plate 1, a driving component 4 provided at the bottom of the top plate 1, and a stabilizing component 5 provided at the bottom of the driving component 4.

[0023] The top plate 1 serves as the top foundation of the overall device, used for installation with the suspended ceiling. The support plate 2 is used to support the vehicle. The mounting components 3 are used to fix the suspended ceiling and the top plate 1 respectively, improving the stability of the overall device. The drive component 4 drives the stabilizing component 5, which in turn limits the movement of the cross frame 8. It should be noted that when the support plate 2 moves to the surface of the ground platform, the vehicle can drive onto the support plate 2 and stop. At this time, the drive component 4 lifts the support plate 2 upwards, thereby lifting the vehicle. At the same time, the top of the support plate 2 is equipped with a limit bar, which can effectively limit the vehicle tires, prevent the vehicle from sliding, and improve parking safety. The ground platform serves as the initial parking and load-bearing foundation, with the support plate 2 located above it. Then, the drive component 4 lifts the support plate 2 and the vehicle to a specific height. The lifted platform provides new parking space for the vehicle. The two work together to make full use of vertical space and realize the three-dimensional parking of multiple vehicles on a limited ground surface.

[0024] The mounting assembly 3 includes a connecting plate 31 that is fixed to the inner wall of the top plate 1 by bolts. A crossbar 32 is fixedly connected to the inner wall of the connecting plate 31 by bolts. A fixing block 33 is fixedly connected to one end of the crossbar 32 by bolts, and the fixing block 33 is fixedly connected to the top wall by bolts.

[0025] The connecting plate 31 connects the crossbar 32 and the top plate 1, serving to fix the crossbar 32. At the same time, the connecting plate 31 is fixed to the ceiling. The crossbar 32 is used to connect the connecting plate 31 and the fixing block 33, transmitting force so that the weight of the top plate 1 can be distributed to the fixing block 33. The fixing block 33 is fixed to the top of the garage wall with bolts, firmly fixing the entire device to the top and preventing the device from loosening or falling.

[0026] The stabilizing component 5 includes a connecting rod 51 disposed on one side of the drive component 4. A mounting bracket 52 is fixedly connected to one side of the connecting rod 51 by bolts. Two plug-in blocks 53 are fixedly connected to one side of the mounting bracket 52.

[0027] The connecting rod 51 is used to connect the moving rod 42 and the mounting bracket 52, thereby driving the mounting bracket 52 to move. The mounting bracket 52 is used to install and fix the plug-in block 53, so that the plug-in block 53 can move with it. The plug-in block 53 is used to insert into the groove 14 of the cross frame 8, which can lock the cross frame 8 and prevent it from unfolding, playing a key role in preventing it from falling. It should be noted that the plug-in block 53 is inserted into the groove 14 to prevent the cross frame 8 from retracting after the hydraulic cylinder 11 fails.

[0028] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] Specifically, the drive assembly 4 includes a dual-axis cylinder 41 fixed to the bottom of the top plate 1 by a positioning plate. The piston rod of the dual-axis cylinder 41 is fixedly connected to a moving rod 42, and one side of the moving rod 42 is fixedly connected to the inner wall of the connecting rod 51.

[0030] When the dual-axis cylinder 41 is running, it can drive the moving rod 42 to move left and right, thereby controlling the movement of the moving rod 42. The moving rod 42 is used to connect the dual-axis cylinder 41 and the connecting rod 51, transmitting the power of the dual-axis cylinder 41 to the stabilizing component 5, thereby driving the connecting rod 51 to move. It should be noted that the dual-axis cylinder 41 has a cylinder body, two parallel piston rods and matching pistons, end caps, seals and internal air passage components. The cylinder body has two parallel receiving holes, and the pistons are fixed to one end of the piston rods respectively, dividing the corresponding receiving holes into independent air chambers. The end cap has inlet and outlet holes that are connected to the air passage. The seals and guide sleeves ensure airtightness and guidance. Based on air pressure drive, the piston is stationary under normal conditions. When one air inlet is open, compressed air enters the corresponding air chamber, pushing the piston and causing the piston rod to extend. At the same time, the gas in the other air chamber is discharged from the exhaust structure through the corresponding air passage. When the air inlet is switched, the gas enters the other air chamber, pushing the piston and causing the piston rod to retract, and the gas in the original air chamber is discharged.

[0031] Specifically, the top of the tray 2 is fixedly connected to two guide rails 6, and the inner wall of the guide rails 6 is slidably connected to a slide block 7.

[0032] The guide rail 6 provides a sliding track for the slide block 7, restricting the slide block 7 to move only in a straight line. The slide block 7 is used to connect the tray 2 and the cross frame 8. When the cross frame 8 moves, it will drive the slide block 7 to slide on the guide rail 6, while supporting the bottom of the cross frame 8.

[0033] Specifically, the top of the slide 7 is rotatably connected to the cross bracket 8 via a connecting seat, and the upper end of the cross bracket 8 is rotatably connected to the connecting seat 9, and the top of the connecting seat 9 is fixedly connected to the bottom of the top plate 1.

[0034] The cross rack 8 consists of two long plates, and the inner wall of the cross rack 8 rotates through a pivot. When it is folded up, the pallet 2 and the vehicle can be lowered down. When it is unfolded, the pallet 2 can be lifted up. The connecting seat 9 is fixed to the top plate 1, allowing the cross rack 8 to rotate around the connecting seat 9.

[0035] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0036] Specifically, the bottom of the top plate 1 is fixedly connected to two fixed seats 10, and each of the two fixed seats 10 is rotatably connected to a hydraulic cylinder 11 on one side. The two hydraulic cylinders 11 are designed symmetrically at the center line of the top plate 1.

[0037] The fixed seat 10 provides rotational support for the hydraulic cylinder 11. When the piston rod of the hydraulic cylinder 11 extends or retracts, it can push the cross frame 8 to unfold or retract via the cross plate 13, thereby controlling the lifting and lowering of the pallet 2. It should be noted that the two hydraulic cylinders 11 are synchronously controlled through a flow divider and combiner valve. The valve group evenly distributes the hydraulic oil to the two cylinders to ensure that the incoming flow is equal. The core of the hydraulic cylinder 11 consists of a cylinder barrel, piston, piston rod, seals, and end caps. The cylinder barrel is the main body with precision machining of the inner wall. The piston is installed inside the cylinder barrel. The seals prevent leakage and divide the cylinder barrel into a rod chamber and a rodless chamber. One end of the piston rod is connected to the piston, and the other end extends out of the cylinder to transmit force. The end cap seals the cylinder barrel and has an oil port. A guide sleeve is provided to ensure the guidance of the piston rod. Its working principle is based on the fact that when high-pressure oil enters the rodless chamber, it pushes the piston and drives the piston rod to extend. The oil in the rod chamber flows back to the oil tank. When high-pressure oil is replaced in the rod chamber, the piston drives the piston rod to retract, and the oil in the rodless chamber is discharged. The movement speed and output force can be adjusted by controlling the oil flow and pressure.

[0038] Specifically, the piston rod of the hydraulic cylinder 11 is rotatably connected to the mounting plate 12, and a horizontal plate 13 is fixedly connected to one side of the mounting plate 12.

[0039] Mounting plate 12 is used to connect the piston rod of hydraulic cylinder 11 and cross plate 13, so that the power of hydraulic cylinder 11 can be transmitted to cross plate 13. Cross plate 13 is used to connect cross frame 8, and hydraulic cylinder 11 pushes cross frame 8 to move through cross plate 13.

[0040] Specifically, the inner wall of the cross rack 8 is provided with a groove 14, and the inner wall of the groove 14 is inserted into the outer side of the plug block 53, and the number of grooves 14 is set to four.

[0041] The groove 14 and the plug block 53 cooperate. After the four plug blocks 53 are inserted into the corresponding groove 14, they can lock the cross frame 8 and prevent it from moving. It should be noted that the four plug blocks 53 are all fixed in shape. Each plug is inserted into the inner wall of the cross frame 8 and forms a square structure, thereby limiting the cross frame 8 and preventing the tray 2 from falling (i.e., the cross frame 8 from folding).

[0042] In use, the connecting plate 31 is fixed to the inner wall of the top plate 1 with bolts. The connecting plate 31 is then connected to the crossbar 32 with bolts. The fixing block 33 at the other end of the crossbar 32 is firmly locked to the top of the garage wall with bolts. The four mounting components 3 are located at the four corners of the top plate 1, distributing the weight of the device evenly to the ceiling load-bearing structure. When the device is in its initial state, the support plate 2 is on the ground, the crossbar 8 is in the retracted state, the dual-axis cylinder 41 is not activated, and the plug block 53 of the stabilizing component 5 is separated from the groove 14 of the crossbar 8, making it easy for the vehicle to drive in. The driver slowly drives the vehicle onto the support plate 2, ensuring that the vehicle's center of gravity is in the center of the support plate 2 before stopping and turning off the engine. The driver then moves to a safe area and activates the two hydraulic cylinders 11 at the bottom of the top plate 1. The fixing seat 10 provides stable support for the hydraulic cylinders 11. The piston rod of the hydraulic cylinder 11 retracts, pushing the crossbar 13 to move through the mounting plate 12. The crossbar 13 drives the crossbar 8 to rotate around the connecting seat 9. At the same time, the bottom of the crossbar 8 pushes the slide 7 to slide inward along the guide rail 6. As the cross rack 8 unfolds, the pallet 2 rises smoothly until it reaches the parking height. Once the pallet 2 reaches the designated position, the hydraulic cylinder 11 stops operating, and the dual-axis cylinder 41 of the drive assembly 4 is activated. The dual-axis cylinder 41 drives two moving rods 42 to move laterally. The moving rods 42 pull the mounting frame 52 to move synchronously via the connecting rod 51. Multiple plug-in blocks 53 on the mounting frame 52 are then inserted into the corresponding grooves 14 on the inner wall of the cross rack 8, locking the extension and retraction freedom of the cross rack 8 and forming a rigid anti-fall structure. When the vehicle needs to be retrieved, the dual-axis cylinder 41 is first activated to reverse the direction, driving the moving rods 42, connecting rods 51, and mounting frame 52 to reset. The plug-in blocks 53 are then pulled out of the grooves 14, releasing the lock on the cross rack 8. Then, the piston rod of the hydraulic cylinder 11 is extended, pulling the cross rack 8 to rotate in the opposite direction via the mounting plate 12 and the cross plate 13. The cross rack 8 gradually unfolds, and the pallet 2 slowly descends to the ground. Once the pallet 2 has completely landed, the hydraulic cylinder 11 is deactivated, and the vehicle owner can then enter the area and drive away the vehicle.
