Description

Technical Field

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

[0002] With the acceleration of urbanization and the continuous increase in car ownership, the parking problem has become increasingly prominent. Multi-level parking garages, as an efficient parking solution for utilizing space resources, have been widely used in commercial centers, residential communities, hospitals, and other locations. They achieve multi-level parking by employing various methods such as lifting and lateral movement, significantly increasing the number of parking spaces per unit area.

[0003] Traditional automated parking garages typically employ simple fall prevention measures. However, the lifting and lowering of the vehicle platform during operation presents numerous safety risks. Due to the involvement of complex mechanical systems such as motor drives, chain or wire rope transmissions, a malfunction in any component—such as a sudden motor failure, chain breakage, or wire rope slack—can cause the vehicle platform to lose normal lifting control and fall. Such falls not only severely damage vehicles parked on the platform but also endanger the lives of people inside the garage and the integrity of surrounding facilities. Therefore, we propose a fall prevention safety device for automated parking garages to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a fall prevention safety device for a multi-level parking garage to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fall arrestor for a multi-level parking garage includes: a mounting plate; a movable seat slidably mounted on the bottom of the mounting plate; a fixed plate, a frame, and a support plate fixedly mounted on the bottom of the mounting plate; a lead screw threadedly connected to the movable seat; a worm gear fixedly mounted on the outer side of the lead screw; the lead screw rotatably mounted inside the fixed plate and on one side of the support plate; a rotating rod rotatably mounted inside the frame; a worm gear fixedly mounted on the outer side of the rotating rod; a connecting plate hinged to the bottom of the movable seat; pin one and pin two slidably mounted inside the two ends of the connecting plate; a hook hinged to the bottom of the connecting plate; a rotating shaft, a limiting shaft, and a rotating shaft fixedly mounted on one side of the fixed plate; the hook rotatably mounted on the outer side of the rotating shaft; and the connecting plate rotatably mounted on the outer side of the rotating shaft.

[0007] Preferably, the first pin is fixedly installed at the bottom of the movable seat, the second pin is fixedly installed at the top of the hook, and both ends of the connecting plate are provided with sliding grooves, and the first pin and the second pin are slidably installed in the corresponding sliding grooves.

[0008] Preferably, the bottom of the mounting plate is provided with a slide rail, and the movable seat is slidably installed in the slide rail.

[0009] Preferably, a drive motor is fixedly installed on one side of the frame, and the rotating shaft is fixedly installed on the output end of the drive motor.

[0010] Preferably, the hook has a limiting groove inside, and the limiting groove is adapted to the limiting shaft.

[0011] Preferably, the worm gear and the worm are meshed, the worm gear and the worm are installed in the frame, and rotating holes are opened on both sides of the frame. The rotating rod and the lead screw are rotatably installed in the corresponding rotating holes.

[0012] In this utility model, a fall arrestor for a three-dimensional parking garage is described, which locks the hook to the vehicle platform. By setting a limiting groove and a limiting shaft, the displacement of the hook is limited to prevent the hook from deviating too much, which would slow down the entire braking process, avoid unnecessary jamming and delay, improve braking efficiency, and enable the fall arrestor to respond and prevent the vehicle platform from falling in the shortest possible time.

[0013] This utility model has a reasonable structural design. The drive motor, rotating rod, and worm gear rotate within the frame. The worm wheel meshes with the worm, driving the lead screw to rotate within the frame. Through the threaded connection between the moving seat and the lead screw, the moving seat moves horizontally under the constraint of the slide rail, causing the first pin to slide in the groove located above the connecting plate. When the first pin is at the top of the corresponding groove, the connecting plate rotates under the constraint of the drive shaft. The rotation of the connecting plate itself, through the cooperation between the second pin and the groove at the bottom of the connecting plate, drives the hook to rotate under the constraint of the rotating shaft. The threaded connection converts the rotational motion of the lead screw into the linear motion of the moving seat. This connection method has self-locking properties, so even after the motor stops rotating, the moving seat can remain in its current position, enhancing the reliability of the braking process. This progressive action design makes the hook lock more smoothly, avoiding damage to the vehicle platform or other components caused by sudden impacts. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A fall arrestor for a multi-level parking garage includes: a mounting plate 1, a movable seat 6 slidably mounted on the bottom of the mounting plate 1, a fixed plate 11, a frame 2, and a support plate 5 fixedly mounted on the bottom of the mounting plate 1, a lead screw 4 threadedly connected inside the movable seat 6, a worm gear 18 fixedly mounted on the outside of the lead screw 4, the lead screw 4 rotatably mounted inside the fixed plate 11 and on one side of the support plate 5, a rotating rod 16 rotatably mounted inside the frame 2, a worm gear 17 fixedly mounted on the outside of the rotating rod 16, a connecting plate 7 hinged to the bottom of the movable seat 6, a first pin 12 and a second pin 13 slidably mounted inside the two ends of the connecting plate 7 respectively, a hook 8 hinged to the bottom of the connecting plate 7, a rotating shaft 9, a limiting shaft 10, and a rotating shaft 20 fixedly mounted on one side of the fixed plate 11, the hook 8 rotatably mounted on the outside of the rotating shaft 9, and the connecting plate 7 rotatably mounted on the outside of the rotating shaft 20.

[0021] In this embodiment, pin 12 is fixedly installed at the bottom of the movable seat 6, and pin 23 is fixedly installed at the top of the hook 8. Slide grooves 19 are provided inside both ends of the connecting plate 7. Pin 12 and pin 23 are slidably installed in the corresponding slide grooves 19 to ensure that the power can be accurately transmitted from the movable seat 6 to the connecting plate 7, thereby driving the subsequent hook 8 to move.

[0022] In this embodiment, a slide rail 15 is provided at the bottom of the mounting plate 1, and the movable seat 6 is slidably installed in the slide rail 15. The guiding function is based on the shape and size accuracy of the slide rail 15, and the cooperation between the slide rail 15 and the movable seat 6 can ensure that the movement path of the movable seat 6 is accurate and predictable.

[0023] In this embodiment, a drive motor 3 is fixedly installed on one side of the frame 2, and a rotating shaft 9 is fixedly installed on the output end of the drive motor 3, which can quickly convert the power of the drive motor 3 into the mechanical motion required for braking, ensuring the timeliness of the braking action.

[0024] In this embodiment, a limiting groove 14 is provided inside the hook 8. The limiting groove 14 is adapted to the limiting shaft 10 to improve the accuracy and reliability of braking.

[0025] In this embodiment, the worm gear 18 and the worm 17 mesh with each other. The worm gear 18 and the worm 17 are installed inside the frame 2. Rotary holes are opened on both sides of the frame 2. The rotating rod 16 and the lead screw 4 are rotatably installed in the corresponding rotating holes, thereby ensuring that the power can be continuously and stably transmitted between the two.

[0026] In this embodiment, when the vehicle platform of the automated parking garage is normally stationary, the fall arrestor is also in standby mode. When the lifting system of the vehicle platform malfunctions, causing the descent speed of the vehicle platform to exceed the preset safety threshold, the drive motor 3 automatically starts, thereby driving the rotating rod 16 and the worm gear 17 to rotate within the frame 2. The worm wheel 18 meshes with the worm gear 17, driving the lead screw 4 to rotate within the frame 2. Through the threaded connection between the movable seat 6 and the lead screw 4, the movable seat 6 moves horizontally under the constraint of the slide rail 15, thereby driving the pin shaft 12 to slide within the slide groove 19 located above the connecting plate 7. When the pin shaft 12 is at the top of the corresponding slide groove 19, the connecting plate 7 is driven to move under the constraint of the drive shaft. The rotation of the connecting plate 7, through the cooperation between the sliding groove 19 at the bottom of the connecting plate 7 and the pin 13, drives the hook 8 to rotate under the restriction of the rotating shaft 9, thereby locking the hook 8 onto the vehicle platform. By setting the limiting groove 14 and the limiting shaft 10, the displacement of the hook 8 is limited to prevent the hook 8 from deviating too much and slowing down the entire braking process. The threaded connection can convert the rotational motion of the lead screw 4 into the linear motion of the moving seat 6. Moreover, this connection method has self-locking properties. Even after the motor stops rotating, the moving seat 6 can remain in the current position, which enhances the reliability of the braking process. This progressive action design makes the hook 8 more stable during the locking process, avoiding sudden impacts that could damage the vehicle platform or other components.

[0027] The above provides a detailed description of a fall arrestor for a multi-level parking garage provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are only intended to aid in understanding the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
