Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figure 1~Figure 5 As shown, this embodiment proposes a safety device for a three-dimensional car park, including a load-bearing beam 1, a lifting mechanism, a vehicle loading tray 2 and an anti-falling mechanism, wherein the vehicle loading tray 2 is slidably arranged on the load-bearing beam 1 with the aid of the lifting mechanism, and the anti-falling mechanism is at least two groups, and the anti-falling mechanism includes a mounting frame 3, an anti-falling drum 4, a wire rope 5, a ratchet 6 and a pawl 7, the mounting frame 3 is arranged on the load-bearing beam 1, the anti-falling drum 4 is rotatably arranged on the mounting frame 3, two ends of the wire rope 5 are respectively connected to the anti-falling drum 4 and the vehicle loading tray 2, the ratchet 6 is arranged on the anti-falling drum 4, and the pawl 7 is swingably arranged on the mounting frame 3, and the pawl 7 is engaged with or unengaged with the ratchet 6 after swinging.
[0022] The cam 3 is used to hold the cam 3 in place and the cam 3 is used to hold the cam 3 in place until the cam 3 is within the range of motion of the cam 3. The cam 3 is used to hold the cam 3 in place and the cam 3 is used to hold the cam 3 in place until the cam 3 is within the range of motion of the cam 3.
[0023] Furthermore, it also includes a hook 8 and a hanging ring 9, one end of the hook 8 is arranged on the end of the steel wire rope 5, and the other end is hooked on the hanging ring 9, and the hanging ring 9 is arranged on the vehicle loading tray 2.
[0024] In this embodiment, a hook 8 is connected to the lower end of the wire rope 5, and a hanging ring 9 is provided on the vehicle loading pallet 2. The hook 8 and the hanging ring 9 are hooked together to ensure the stable bearing capacity of the vehicle loading pallet 2. The structure of the hook 8 and the hanging ring 9 facilitates disassembly and installation.
[0025] Furthermore, it also includes a spring 10 and an electromagnet 11, wherein the two ends of the spring 10 act on the pawl 7 and the mounting frame 3 respectively, for providing a force for the pawl 7 to move away from the ratchet 6, and the electromagnet 11 is arranged on the mounting frame 3, and after being energized, the electromagnet 11 is used to provide a force for the pawl 7 to move closer to the ratchet 6.
[0026] In this embodiment, the swing of the pawl 7 is controlled by the electromagnet 11 and the spring 10. Under normal conditions, the spring 10 provides a force for the pawl 7 to swing away from the ratchet 6, so that the ratchet 6 and the anti-fall drum 4 can rotate normally. When the vehicle pallet 2 falls unexpectedly, the electromagnet 11 is energized, and the magnetic force of the electromagnet 11 repels the pawl 7, thereby overcoming the elastic force of the spring 10 and causing the pawl 7 to swing in the direction of the ratchet 6, eventually causing the pawl 7 to engage with the ratchet 6, locking the ratchet 6 and preventing it from rotating, thereby achieving the effect of locking the anti-fall drum 4. At this time, the connection between the hook 8 and the hanging ring 9 provides a bearing capacity for the vehicle pallet 2, thereby playing an anti-falling role.
[0027] Furthermore, the hook 8 is provided with a gravity sensor 12 , and the gravity sensor 12 is used to detect the force carried by the hook 8 , and the gravity sensor 12 is electrically connected to the electromagnet 11 .
[0028] In this embodiment, in order to ensure that the electromagnet 11 can be automatically energized in the event of an accident, a gravity sensor 12 is provided on the hook 8 to detect the weight carried by the hook 8 in real time. In a normal state, the hook 8 and the lifting mechanism jointly carry the vehicle pallet 2. When the lifting mechanism is damaged, it can no longer provide bearing capacity. At this time, the weight of the vehicle pallet 2 is completely applied to the hook 8. The gravity sensor 12 detects the abnormal change in weight and sends a signal to the controller of the electromagnet 11. The controller controls the electromagnet 11 to be energized instantly to ensure the timeliness of anti-falling.
[0029] Furthermore, the anti-falling reel 4 , the ratchet 6 and the pawl 7 are each two in number, and a connecting rod 13 is also included, the two ends of the connecting rod 13 are respectively arranged on the two pawls 7 , and the electromagnet 11 is located at the connecting rod 13 .
[0030] In the present embodiment, on the same side of the load-bearing beam 1, there are two anti-falling drums 4, ratchet wheels 6 and pawls 7. In the event of an accident, if the anti-falling drums 4 on both sides cannot be locked at the same time, the vehicle loading tray 2 may fall to one side. In order to avoid this phenomenon, the two pawls 7 are connected as a whole by a connecting rod 13, and the electromagnet 11 is located at the connecting rod 13, so that the two pawls 7 share one electromagnet 11, realizing synchronous control of the two pawls 7, thereby ensuring the consistency of the locking of the anti-falling drums 4 on both sides.
[0031] Furthermore, it also includes a motor 14, a slide 15 and a polygonal column 16, the slide 15 is slidably arranged on the mounting frame 3, the sliding direction of the slide 15 is parallel to the axial direction of the anti-fall reel 4, the motor 14 is arranged on the slide 15, the polygonal column 16 is arranged on the output shaft of the motor 14, the anti-fall reel 4 is provided with a polygonal hole 17 along the axial direction, the polygonal column 16 has the same shape as the polygonal hole 17, and after the slide 15 slides, the polygonal column 16 enters or leaves the polygonal hole 17.
[0032] In this embodiment, after an accident occurs, the safety of the vehicle pallet 2 is ensured by the anti-fall mechanism, and then the anti-fall reel 4 can be driven by the motor 14 to reverse, so as to lift the vehicle pallet 2 for easy maintenance. For this purpose, a slide 15 and a polygonal column 16 are provided. Under normal conditions, the slide 15 is away from the anti-fall reel 4 and does not interfere with the rotation of the anti-fall reel 4. When the anti-fall mechanism is activated, the slide 15 can be controlled to slide close to the anti-fall reel 4, and the polygonal column 16 can be inserted into the polygonal hole 17 on the anti-fall reel 4 to achieve the clamping connection between the two. Then the motor 14 is started, and the transmission effect is realized through the cooperation of the polygonal column 16 and the polygonal hole 17, which drives the anti-fall reel 4 to reverse and lift the vehicle pallet 2.
[0033] Furthermore, the lifting mechanism includes a lifting drum 18 and a chain 19, the lifting drum 18 is rotatably arranged on the load-bearing beam 1, and two ends of the chain 19 are respectively connected to the lifting drum 18 and the vehicle loading tray 2.
[0034] The lifting mechanism is provided in four groups, which are respectively located at the four corners of the vehicle loading tray 2 .
[0035] In this embodiment, the lifting mechanism adopts a common lifting method in the prior art, preferably in the form of a lifting drum 18 and a chain 19. The lifting drum 18 is controlled to rotate by a driving source, and a lifting force is applied to the vehicle pallet 2 with the help of the chain 19 to control the lifting and lowering of the vehicle pallet 2. In order to ensure the lifting stability and uniformity of the pulling force, a group of lifting mechanisms are respectively arranged at the four corners of the vehicle pallet 2.
