DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0025] An attached lifting scaffold safety warning device includes a mounting frame 1. A connecting plate 2 is mounted on the front of the mounting frame 1. Moving wheels 3 are rotatably connected to the back of the connecting plate 2 and on both sides of the mounting frame 1. A housing 4 is fixedly mounted on the back of the connecting plate 2 and on both sides of the mounting frame 1. A fall protection component 5 is mounted on the inner side of the housing 4. A warning mechanism 6 is fixedly mounted on the outer side of one set of housings 4.

[0026] First, in this embodiment, the specific structure of the early warning mechanism 6 is as follows:

[0027] The warning mechanism 6 includes a mounting plate 601 fixedly installed on the top of the housing 4. A connecting frame 602 is fixedly connected to the top of the mounting plate 601. A speed measuring wheel 603 is rotatably connected to the inner side of the connecting frame 602, and the speed measuring wheel 603 is in contact with the surface of the mounting bracket 1. A Hall speed sensor 604 is installed on the left end of the connecting frame 602 and on the front of the speed measuring wheel 603. Multiple sets of induction magnetic sheets 605 are embedded in the side of the speed measuring wheel 603 near the Hall speed sensor 604. An audible and visual alarm 606 is fixedly installed on the front of the mounting plate 601. The mounting bracket 1 is installed on the wall, and the connecting plate 2 is connected to the foot. The scaffolding is installed and connected. When the scaffolding is raised and lowered normally, the speed measuring wheel 603 rolls against the outside of the mounting frame 1. The Hall speed sensor 604 is equipped with a microcontroller such as Arduino. When the speed measuring wheel 603 rotates, multiple sets of sensing magnetic sheets 605 rotate accordingly. When passing the Hall speed sensor 604, they receive pulse signals to calculate the real-time speed. The microcontroller sets the speed threshold through programming. When the scaffolding falls, the alarm logic is triggered when the limit is exceeded. The microcontroller controls the audible and visual alarm 606 to provide audible and visual alarms, thereby providing timely safety warnings to prevent non-working personnel from entering the danger zone.

[0028] Furthermore, both ends of the speed measuring wheel 603 are rotatably connected to the connecting frame 602 via bearings 607. Isolation sleeves 608 are fixedly connected between the outer sides of multiple sets of induction magnetic sheets 605 and the speed measuring wheel 603. The speed measuring wheel 603 rotates flexibly inside the connecting frame 602 via bearings 607, and the isolation sleeves 608 are used to prevent external magnetic field interference.

[0029] Then, recessed mounting holes 101 are provided at both the top and bottom of the mounting bracket 1, and scaffolding mounting edges 201 are fixedly connected to both the left and right ends of the front of the connecting plate 2. The mounting bracket 1 is installed on the wall through the recessed mounting holes 101, and the connecting plate 2 is installed and connected to the scaffolding through the scaffolding mounting edges 201 on the front.

[0030] Furthermore, the front ends of both sets of movable wheels 3 are rotatably connected to the connecting plate 2 via a rotating shaft 301, and both sets of movable wheels 3 are in contact with the surface of the mounting frame 1. When the scaffolding is raised or lowered, the movable wheels 3 roll against the outside of the mounting frame 1, thereby driving the connecting plate 2 to move stably.

[0031] Secondly, the fall arrestor assembly 5 includes anti-reverse wheels 501 rotatably connected inside the two sets of housings 4. A transmission gear ring 502 is fixedly mounted on the front of each of the two sets of anti-reverse wheels 501. The left and right ends of the back of the connecting plate 2 are meshed with the transmission gear ring 502 via transmission gears 503. An electric lifting rod 504 is fixedly mounted on the front of the connecting plate 2. A drive rack 505 is fixedly mounted on the drive end of the electric lifting rod 504, located on the back of the connecting plate 2, and both sets of transmission gears 503 mesh with the drive rack 505. The outer side of the anti-reverse wheels 501... Multiple sets of anti-fall grooves 506 are provided, and multiple sets of slots 507 are provided on both the left and right sides of the mounting frame 1. While the audible and visual alarm is activated, the electric lifting rod 504 is activated to lower the drive rack 505. The drive rack 505 drives the transmission gear 503 to rotate, which in turn drives the two sets of anti-fall wheels 501 to rotate under the transmission ring 502. This causes the anti-fall grooves 506 on the outer side of the anti-fall wheels 501 to fit into the multiple sets of slots 507, thereby greatly increasing the friction of the anti-fall wheels 501 to play a role in preventing falls and thus improving the safety of the scaffolding.

[0032] Finally, the bottom of the electric lifting rod 504 is fixedly connected to the connecting plate 2 via the support plate 508, and the output end of the electric lifting rod 504 is fixedly connected to the top of the drive rack 505 via the connecting rod 509. A groove 510 is provided on the front of the connecting plate 2 at the position corresponding to the connecting rod 509. The electric lifting rod 504 drives the drive rack 505 to move via the connecting rod 509, while the connecting rod 509 slides inside the groove 510 to ensure its stability.

[0033] In this embodiment, the specific implementation scenario is as follows: the mounting frame 1 is installed on the wall, and the connecting plate 2 is installed and connected to the scaffolding. When the scaffolding is raised and lowered normally, the moving wheel 3 rolls against the outside of the mounting frame 1, and the speed measuring wheel 603 rolls against the outside of the mounting frame 1. The Hall speed sensor 604 is equipped with a microcontroller such as Arduino. When the speed measuring wheel 603 rotates, multiple sets of sensing magnetic sheets 605 rotate accordingly. When passing the Hall speed sensor 604, they receive pulse signals to calculate the real-time speed. The microcontroller sets the speed threshold through programming, and when the scaffolding falls, exceeding the limit triggers the alarm logic. The microcontroller controls the audible and visual alarm 6. 06. An audible and visual alarm is activated. Simultaneously, the electric lifting rod 504 is activated, lowering the drive rack 505. The drive rack 505 drives the transmission gear 503 to rotate, which in turn drives the two sets of anti-reverse wheels 501 to rotate under the transmission ring 502. This causes the anti-reverse groove 506 on the outer side of the anti-reverse wheel 501 to engage with multiple sets of slots 507, greatly increasing the friction of the anti-reverse wheel 501 to prevent falls. The entire operation is simple and convenient. This utility model, through its design, can provide timely safety warnings to prevent non-working personnel from entering dangerous areas, and can also prevent falls when the scaffolding is falling, thereby improving the safety of the scaffolding.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
