Description

Technical Field

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

[0002] Currently, fall protection devices in automated parking systems can be broadly categorized into two types: fall arrest hooks and fall arrest frames. While both fall arrest methods provide protection, they only address the end of the equipment. This means that a fall has already occurred, and the protection is a remedy rather than a preventative measure against the root cause. For example, broken steel cables, slippage in the power transmission, or disengagement of the power transmission gears can all lead to a fall. How to prevent falls from the source has always been a challenging problem for those skilled in the art.

[0003] Therefore, in the field of automated parking system technology, there is still a need for research and improvement of anti-fall devices for automated parking systems. This is a current research hotspot and focus in the field of automated parking system technology, and it is also the starting point for the completion of this utility model. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide a fall prevention device for a three-dimensional parking garage, so as to solve the technical problem of the elevator falling due to the disengagement of the power transmission gear pair.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a three-dimensional parking garage anti-fall device, including a gear pair installed on a steel structure frame, the driving gear of the gear pair being connected to a power device, the driven gear of the gear pair being rotatably installed on the steel structure frame, the driven gear being fixedly installed with a transmission shaft, a stop plate being fixedly installed on the transmission shaft, the stop plate having an oblong groove coaxial with the transmission shaft, and a sliding pin adapted to the oblong groove being slidably installed on the steel structure frame, the sliding pin being connected to a linear drive mechanism.

[0006] As an improvement, a slide block is fixedly installed on the steel structure frame, and the sliding pin is slidably installed on the slide block.

[0007] As a further improvement, the linear drive mechanism includes a drive motor fixedly mounted on the steel structure frame, a connecting plate fixedly mounted on the power output shaft of the drive motor, a sliding shaft provided on the connecting plate, the sliding shaft being eccentrically arranged with the power output shaft of the drive motor, a fixing plate fixedly mounted on the end of the sliding pin, a sliding groove extending radially along the sliding pin being opened on the fixing plate, and the sliding shaft being constrained and installed in the sliding groove.

[0008] As another improvement, the stop plate is disc-shaped, and the stop plate has a plurality of waist-shaped grooves arranged in a ring.

[0009] After adopting the above technical solution, the beneficial effects of this utility model are:

[0010] This utility model embodiment achieves the locking or releasing of the driven gear by driving the sliding pin to insert into or disengage from the waist-shaped groove, thus effectively preventing the driven component from falling. Furthermore, this structure achieves fall prevention from the power source, further improving the safety performance of the automated parking system.

[0011] Because the sliding pin is slidably mounted on the slide block, it improves both the smoothness of the sliding pin's movement and its stability under force, enabling it to withstand greater forces.

[0012] Because the stop plate has several waist-shaped grooves in a ring array, it can lock the stop plate at multiple positions, thus improving the accuracy of the locking position. Attached Figure Description

[0022] Example 1:

[0023] like Figure 1 As shown, this utility model provides a fall prevention device for a multi-level parking garage, including a gear pair installed on a steel structure frame 1. The driving gear 3 of the gear pair is connected to a power unit 2, which is typically a combination of a motor and a reducer. The motor and reducer are fixedly installed on the steel structure frame 1. The driving gear 3 of the gear pair is installed on the power output shaft of the motor and reducer. The driven gear 4 of the gear pair is rotatably installed on the steel structure frame 1. A transmission shaft 5 is fixedly installed on the driven gear 4, and a stop plate is fixedly installed on the transmission shaft 5. Here, for ease of installation and use, the transmission... The shaft 5 is rotatably mounted on the steel frame 1 via a bearing seat. The driven gear 4 and the stop plate 6 are fixed at both ends of the shaft 5, respectively. The stop plate 6 has a waist-shaped groove 13 coaxial with the shaft 5. A sliding pin 8 that matches the waist-shaped groove 13 is slidably mounted on the steel frame 1. The sliding pin 8 is connected to the linear drive mechanism. A slide block 7 is fixedly mounted on the steel frame 1. The sliding pin 8 is slidably mounted on the slide block 7. On the one hand, this improves the sliding smoothness of the sliding pin 8. On the other hand, it improves the stress stability of the sliding pin 8 and enables it to withstand greater forces.

[0024] The linear drive mechanism includes a drive motor fixedly mounted on a steel frame 1. A connecting plate 9 is fixedly mounted on the power output shaft of the drive motor. A sliding shaft 11 is provided on the connecting plate 9. The sliding shaft 11 is eccentrically positioned with respect to the power output shaft of the drive motor. A fixing plate 10 is fixedly mounted on the end of a sliding pin 8. A groove 12 extending radially along the sliding pin 8 is formed on the fixing plate 10. The sliding shaft 11 is constrained and installed within the groove 12. The diameter of the sliding shaft 11 is adapted to the width of the groove 12. The length of the groove 12 is greater than the stroke of the sliding shaft 11. Figure 2 and Figure 3 As shown, the drive motor rotates to drive the connecting plate 9 to rotate, thereby driving the sliding shaft 11 to reciprocate within the sliding groove 12, which in turn drives the sliding pin 8 to reciprocate linearly. This allows the sliding pin 8 to be inserted into or removed from the waist-shaped groove 13, forming an anti-fall state and a release state.

[0025] When the gear pair is not working, such as Figure 2 As shown, the drive motor drives the sliding pin 8 to insert into the oblong groove 13, locking the transmission shaft 5, thereby locking the driven gear 4 and preventing the gear pair from disengaging and causing the driven gear 4 to continue rotating under external force, thus preventing the driven component from falling off; when the gear pair is working, as Figure 3 As shown, the drive motor drives the sliding pin 8 to disengage from the waist-shaped groove 13, releasing the transmission shaft 5, thereby releasing the driven gear 4 and ensuring the normal operation of the gear pair.

[0026] This invention prevents falls from the power source, further improving the safety performance of multi-level parking garages.

[0027] Example 2:

[0028] like Figure 4 As shown, this utility model provides a three-dimensional parking garage anti-fall device, whose structure is basically the same as that of Embodiment 1. The difference is that the stop plate 6 is disc-shaped, and there are several waist-shaped grooves 13 arranged in a ring on the stop plate 6, which can realize the locking of the stop plate 6 at multiple positions and improve the accuracy of the locking position.

[0029] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
