Detailed Description of the Preferred Embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-6 , the floating dock aerial footbridge includes an upper support seat 1 and a lower support seat 2. Both the upper support seat 1 and the lower support seat 2 are connected to the side wall of the dock. The upper support seat 1 is rotatably connected with a footbridge bridge body 3. The footbridge bridge body 3 is flush with the dock top deck, and safety railings 10 are provided on both sides of the footbridge bridge body 3. A footbridge support 5 is provided under the footbridge bridge body 3. The bottom end of the footbridge support 5 is rotatably connected to the lower support seat 2. A drive motor 4 is provided under the upper support seat 1. The output end of the drive motor 4 penetrates the upper support seat 1 and is connected to the footbridge bridge body 3;

[0028] In the present utility model, an upper support base 1 and a lower support base 2 are provided. The upper support base 1 plays a role in supporting and limiting the footbridge body 3, enabling the footbridge body 3 to rotate around the upper support base 1. During use, the footbridge body 3 is rotated and docked to achieve the through - connection of the passage. When not in use, the footbridge body 3 is rotated and opened to avoid affecting the operation of the floating dock. Additionally, the lower support base 2 can stably and firmly support the footbridge body 3 by means of the footbridge support 5 rotatably connected thereto, keeping the footbridge body 3 in a horizontal state and preventing the problem of the end of the footbridge body 3 sagging due to its excessive length.

[0029] One end of the footbridge body 3 far from the upper support base 1 is provided with a receiving groove 13. A diagonal compensation component 6 is slidably connected in the receiving groove 13. The diagonal compensation component 6 is used to fill the length reduced by the footbridge body 3 avoiding the rotation diagonal.

[0030] The diagonal compensation component 6 includes a compensation plate 601, a spring 602, and a support slide bar 603. The compensation plate 601 is slidably connected in the receiving groove 13. The support slide bar 603 is arranged inside the receiving groove 13 and is slidably connected to the compensation plate 601. A spring 602 is provided on the side of the support slide bar 603. One end of the spring 602 is connected to the receiving groove 13, and the other end of the spring 602 is connected to the compensation plate 601, and the spring 602 applies an outward thrust to the compensation plate 601.

[0031] By providing the compensation plate 601 and the spring 602, since the footbridge body 3 is symmetrically arranged and the rotation and closing directions are opposite, the diagonals of the footbridge body 3 will collide with each other. To avoid collisions and ensure that the footbridge body 3 can be aligned smoothly, the footbridge body 3 will shorten a certain distance to avoid the diagonals. This will result in a certain gap remaining after the footbridge body 3 is aligned. When workers pass through the footbridge body 3 at night or when they are inattentive, there is a risk of getting stuck in the gap. The compensation plate 601 and the spring 602 can automatically fill the gap. When the diagonals of the footbridge body 3 come into contact, the compensation plate 601 will be squeezed and contract into the receiving groove 13 to avoid the diagonals. When the footbridge body 3 is aligned, the compensation plate 601 will be pushed out by the spring 602 and fit with the compensation plate 601 on the other side to achieve the purpose of filling the diagonal gap and avoid potential risks.

[0032] The footbridge body 3 is provided with an anti - slip cushion plate 7. The anti - slip cushion plate 7 is detachably connected to the footbridge body 3, and the anti - slip cushion plate 7 is used to increase the friction between the footbridge body 3 and the sole of the shoe.

[0033] By setting the anti-slip pad 7, the anti-slip pad 7 can increase the friction between the sole of the shoe and the bridge body 3 of the footbridge, making the worker walk more steadily and avoiding the problem of slipping. At the same time, the anti-slip pad 7 can also protect the bridge body 3 of the footbridge, avoiding the problem of wear on the bridge body 3 of the footbridge caused by long-term walking. And after the anti-slip pad 7 is worn, it can be quickly disassembled and replaced.

[0034] A pressure sensor 12 is provided at the position of the bridge body 3 of the footbridge corresponding to the anti-slip pad 7. The pressure sensor 12 is used to detect the stress state of the anti-slip pad 7, and the pressure sensor 12 is electrically connected to the drive motor 4;

[0035] By setting the pressure sensor 12, the pressure sensor 12 can judge whether there is a worker on the bridge body 3 of the footbridge by sensing the stress condition of the anti-slip pad 7. When there is a worker on the bridge body 3 of the footbridge, the pressure sensor 12 will be triggered and send a signal to the drive motor 4 to make the drive motor 4 in a locked state, preventing the drive motor 4 from driving the bridge body 3 of the footbridge to rotate when there is a worker on the bridge body 3 of the footbridge, effectively ensuring the safety of the worker.

[0036] A number of buzzer warning lights 11 are provided on the guardrail 10. The buzzer warning lights 11 are arranged at equal distances, and the buzzer warning lights 11 are electrically connected to the pressure sensor 12;

[0037] By setting the buzzer warning lights 11, the buzzer warning lights 11 can emit warning lights at night or in low visibility conditions, facilitating the worker to judge the boundary of the bridge body 3 of the footbridge and the position of the guardrail 10, so as to achieve the purpose of warning the worker. In addition, the buzzer warning lights 11 are connected to the pressure sensor 12, so that it can receive the information of the pressure sensor 12. When the pressure sensor 12 senses that the bridge body 3 of the footbridge is overloaded due to excessive force, it will send a signal to the buzzer warning lights 11, and use the buzzer warning lights 11 to emit warning lights and buzzer alarms to prompt the worker that the bridge body 3 of the footbridge is overloaded at this time.

[0038] A lifting ring 9 is provided on the footbridge body. The lifting ring 9 is located at the lifting balance point of the bridge body 3 of the footbridge and the footbridge support 5. The lifting ring 9 is used to maintain the balance of the bridge body 3 of the footbridge and the footbridge support 5 during lifting;

[0039] By setting the lifting ring 9, the lifting ring 9 can be quickly connected to the lifting equipment to achieve the purpose of quickly lifting the bridge body 3 of the footbridge. In addition, the setting position of the lifting ring 9 is at the balance point of the bridge body 3 of the footbridge and the footbridge support 5, so that when the bridge body 3 of the footbridge is lifted, it can be kept in a horizontal state, facilitating the installation or disassembly work.

[0040] A limiting stop bar 8 is rotatably connected to the position near the front end of the guardrail 10. The other end of the limiting stop bar 8 is aligned with the guardrail 10 on the other side, and an electric buckle 15 is provided at the position of the guardrail 10 on the other side corresponding to the limiting stop bar 8;

[0041] By setting the limit stop rod 8 and the electric buckle 15, the limit stop rod 8 can block the front end of the footbridge body 3 and connect the guardrails 10 on both sides, so that the front end of the footbridge body 3 is closed. At the same time, the electric buckle 15 is used to lock the limit stop rod 8. In this way, it can be avoided that the front end of the footbridge body 3 is opened randomly, resulting in the risk that workers are prone to fall.

[0042] A laser rangefinder 14 is provided at the front end of the footbridge body 3. The laser rangefinder 14 is used to detect whether there is an object at the front end of the footbridge body 3, and the laser rangefinder 14 is electrically connected to the electric buckle 15.

[0043] By setting the laser rangefinder 14, the laser rangefinder 14 can detect whether there is an object at the front end. When the alignment ports of the footbridge bodies 3 on both sides are aligned, the laser rangefinder will sense the object at the front end and send a signal to the electric buckle 15. After receiving the signal, the electric buckle 15 will unlock the limit stop rod 8, so that the limit stop rod 8 can be opened. Similarly, when the laser rangefinder cannot sense the object in front, it will judge that the footbridge bodies 3 are not aligned, and will send a signal to lock the limit stop rod 8 to the electric buckle 15, so that the limit stop rod 8 cannot be opened when the footbridge bodies 3 are not aligned, avoiding the problem of accidental opening of the limit stop rod 8.

[0044] Working principle:

[0045] During use, the driving motor 4 drives the footbridge body 3 to rotate 90 degrees through the upper support seat 1. At the same time, the footbridge support 5 rotates synchronously with the lower support seat 2 as the center. When the diagonals of the footbridge bodies 3 on both sides are fitted, the compensation plate 601 will be compressed and retracted into the storage groove 13. When the footbridge bodies 3 are aligned, the compensation plate 601 will protrude under the push of the spring 602 to fill the gap. At the same time, the laser rangefinder 14 detects the object in front and sends an unlocking signal to the electric buckle 15, so that the limit stop rod 8 can be opened to realize the through passage.

[0046] As described above, the utility model sets the footbridge body and the footbridge support. During use, the driving motor drives the footbridge body to rotate 90 degrees through the upper support seat, so that the footbridge bodies on both sides are aligned. At the same time, the footbridge support under the footbridge body also rotates 90 degrees with the lower support seat as the center. The footbridge body is stably and firmly supported by the footbridge support, avoiding the problem that the footbridge body sags due to its too long length. And by docking the footbridge bodies on both sides, the purpose of connecting the side walls of the two floating docks is realized, solving the problem that the traditional method requires going up and down the dock through stairs, greatly improving the traffic efficiency, and avoiding the problem that the passage is slippery due to contact with seawater, effectively ensuring the safety of workers.

[0047] Meanwhile, by setting the anti-slip pad and the pressure sensor, the anti-slip pad can increase the friction between the bridge body and the sole of the shoe, making the workers more stable when passing, avoiding the problem of workers slipping, and further ensuring the safety of the workers. At the same time, when the workers step on the anti-slip pad, it will be detected by the pressure sensor, causing the pressure sensor to send a signal to the drive motor. When the drive motor receives the signal from the pressure sensor, it will be in a locked state. At this time, the drive motor cannot work and cannot drive the bridge body, avoiding the problem of the bridge body rotating and shaking when the drive motor works while the workers are on the bridge body, and further ensuring the safety of the workers.

[0048] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
