Abstract
Description
Technical Field
[0001] This invention belongs to the field of safety net technology, and more specifically, relates to a rapid disassembly and monitoring system and method for intelligent safety nets on large-span steel structure roofs. Background Technology
[0002] Safety is paramount during construction, especially for work at heights. Safety nets, as a common protective device, effectively prevent falls and ensure the safety of construction workers and maintain order on the construction site. However, traditional safety net installation methods have several problems, such as cumbersome installation and removal processes, high labor costs, low construction efficiency, and poor adaptability. Furthermore, when safety nets are subjected to significant impact, their protective performance may be compromised, or they may even break, failing to effectively prevent further falls of objects or people.
[0003] In the prior art, Chinese patent CN202410975498.7 provides an overload buffer device and method for using a fall arrest safety net, including: a support column, a first buffer component, and a second buffer component; the support column is a cylinder with external threads, the external threads being located in the middle of the support column, and a base plate is fixed to the bottom end of the support column, the base plate being fixed to the ground with bolts; the first buffer component is sleeved on the support column and connected to the support column by threads, and is longitudinally limited on the support column by a limiting structure; one end of the second buffer component is located on the first buffer component, and the other end is connected to the fall arrest safety net; when the impact force caused by an object falling from the fall arrest safety net is about to reach its maximum impact force, the limiting structure fails, and the first buffer component rotates and slides down on the support column to offset the impact force on the fall arrest safety net. By slowly descending to offset the impact force, the fall arrest safety net is prevented from breaking and causing the falling object or worker to continue falling, thus improving the protective effect of the fall arrest safety net.
[0004] However, this technology is mainly for overload buffering and does not solve the problems of rapid installation, relocation, or track adaptation of safety nets, resulting in limited functionality; maintenance costs may be high, and complex buffer structures may require regular inspection and maintenance, increasing the cost of use.

When an AI monitoring alarm detects a person or object falling above the safety net, it intelligently identifies the person or object and issues an alarm, sending the alarm information to a backend monitoring unit. An impact value transmitter records the maximum impact weight of the falling person or object and sends it to the backend monitoring unit. The monitoring unit controls the horizontal and vertical movement mechanisms to drive the safety net to the corresponding position. This achieves an integrated upgrade of the safety net system from mechanical support and protective buffering to intelligent monitoring and data early warning, improving the inherent safety level in high-altitude work environments.

[0016] According to another aspect of the present invention, a method for rapid disassembly and monitoring of intelligent safety nets for large-span steel structure roofs is provided, implemented using the aforementioned system for rapid disassembly and monitoring of intelligent safety nets for large-span steel structure roofs, comprising: S100: Determine the installation distance and cable length between the two support platforms of the cable circulation transmission mechanism according to the size of the factory and the actual situation.

S500: The remote-controlled electric drive lifting device raises the hook to the predetermined safety net installation layer; when a person or object falls onto the safety net, the AI monitoring alarm will intelligently identify that there is a person or object on the safety net and issue an alarm, then send the alarm information to the background monitoring unit. The impact value transmitter will record the maximum impact weight of the person or object falling and also send it to the background monitoring unit. S600: The background monitoring unit can organize the data collected from the impact value transmitter and AI monitoring alarm into daily, weekly and monthly reports and synchronize them with the mobile APP in real time.

The background monitoring unit controls the horizontal and vertical movement mechanisms to drive the safety net to the corresponding position. This realizes the integrated upgrade of the safety net system from mechanical support and protective buffer to intelligent monitoring and data early warning, improving the inherent safety level in high-altitude working environments. It is suitable for complex construction scenarios such as large-span or irregularly shaped steel structure workshops.
[0018] 2. The system of this invention is equipped with a steel cable circulation transmission mechanism that is both electrically and manually driven.

[0020] 4. The system of this invention features AI monitoring and alarm devices deployed diagonally across the safety net to dynamically identify and classify falling objects (people or objects), and simultaneously upload event images and videos to the backend system.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0027] like Figure 1-8As shown, this embodiment of the invention provides a rapid disassembly and monitoring system for a large-span steel structure roof intelligent safety net, including a cable circulation transmission mechanism 13, an electric drive lifting device 8 fixed to a steel cable 9 on the cable circulation transmission mechanism 13, an impact value transmitter 11 connected to the end of the hook rope of the electric drive lifting device 8, an AI monitoring alarm 22 installed on the electric drive lifting device 8, and a background monitoring unit 27. The cable circulation transmission mechanism 13 includes two side support platforms 20 and a middle steel cable 9, which can be driven by a motor 16 to perform cyclical movement, or manually driven by two side rockers. The electric drive lifting device 8 is remotely controlled to perform up and down lifting movements. The impact value transmitter 11 is connected to the safety net 12. When a person or object falls onto the safety net 12, the AI monitoring alarm 22 intelligently identifies the person or object on the safety net 12 and issues an alarm, sending the alarm information to the background monitoring unit 27. The impact value transmitter 11 also records the maximum impact weight of the person or object falling and sends it to the background monitoring unit 27. The background monitoring unit 27 records the number of alarms and impact values in real time and generates a daily report. The system of this invention, through an AI monitoring alarm, intelligently identifies a person or object falling above the safety net, issues an alarm, and sends the alarm information to the background monitoring unit. The impact value transmitter records the maximum impact weight of the person or object falling and sends it to the background monitoring unit. The background monitoring unit controls the horizontal and vertical movement mechanisms to drive the safety net to the corresponding position. This achieves an integrated upgrade of the safety net system from mechanical support and protective buffering to intelligent monitoring and data early warning, improving the inherent safety level in high-altitude work environments. It is suitable for complex construction scenarios such as large-span or irregularly shaped steel structure workshops.
[0028] like Figure 4As shown, one side platform of the cable circulation transmission mechanism 13 includes a support platform 20, a fixed frame 19 mounted on the support platform 20, a transmission shaft 15 mounted in the fixed frame 19, a rotating disk 17 connected to one end of the transmission shaft 15, a crank 14 mounted on the rotating disk 17, a motor 16 connected to the other end of the transmission shaft 15, and a control box 18 mounted on the fixed frame 19. The control box 18 can receive remote control messages in real time and send clockwise or counterclockwise movements to the motor 16. The remote-controlled mechanical transmission structure is stable and reliable, and the operation is more convenient and faster. It can ensure that the cable 9 operates efficiently as required, providing continuous and stable power support for the lifting, positioning, and other functions of related equipment such as the safety net 12, ensuring the implementation of the core functions of the overall safety protection system. It will also receive relevant data information from the impact value transmitter 11, summarize it, and then send it to the background monitoring unit 27. This design allows the cable transmission mechanism to form an intelligent linkage with other safety equipment, enabling centralized management of the operating status and abnormal information of the entire safety system, improving the system's collaborative efficiency and intelligence level. The rotating rod at the head of motor 16 drives the transmission shaft 15 to move, thereby causing the steel cable 9 on the transmission shaft 15 to circulate. The system of this invention is equipped with an electrically driven lifting device, which can achieve vertical lifting and horizontal displacement under remote control, significantly improving the efficiency and flexibility of safety net installation and dismantling. The matching U-shaped steel cable clamp adopts an anti-slip design, effectively preventing the device from shifting or falling off under high impact forces, thus improving system stability.
[0029] like Figure 5 As shown, the other platform of the cable circulation transmission mechanism 13 includes a support platform 20, a rotating disk 17 mounted on the support platform 20, a fixed frame 19 mounted on the support platform 20, and a crank 14 mounted on the rotating disk 17. In case of motor 16 failure or power outage, the crank 14 can be manually turned, causing the rotating disk 17 to drive the transmission shaft 15 in a circular motion, thereby causing the steel cable 9 wound on the transmission shaft 15 to circulate. This allows the device to operate efficiently and stably both with and without power. This dual-mode design of "electric as the main power and manual as the auxiliary power" completely eliminates the dependence on a single power source, ensuring that the device can operate efficiently and stably under any circumstances, greatly improving the reliability and risk resistance of the system. The system of this invention is equipped with a cable circulation transmission mechanism with both electric and manual drives. By combining motor drive and manual crank operation, it ensures that the cable circulation motion can still be completed in the event of power failure or equipment failure, ensuring the continuity and reliability of the safety net system. This mechanism has good adaptability and stability and can be widely used in roof structures of different spans.
[0030] like Figure 6As shown, the electric lifting device 8 includes a motor 16, a cable clamp 21 mounted on the cable 9, a winch 24 connected to the motor 16, and a remote control module 23 mounted on the motor 16. After receiving information from the remote control module 23, the motor 16 can drive the hook rope 10 to stretch up and down with the cooperation of the motor 16 and the remote control module 23. At the same time, it can move left and right with the cyclic drive of the cable 9, allowing the device to flexibly adjust its position according to actual operation needs and adapt to different safety net 12 coverage areas or construction scenarios. The electric lifting device 8 is equipped with two steel cable clamps 21. Each steel cable clamp 21 consists of a U-shaped clamp similar to that of the steel cable 9 and a hexagonal tightening bolt. It can fix or loosen the electric lifting device 8 on the steel lock. The contact position between the U-shaped clamp and the steel cable 9 is equipped with anti-slip measures so that if construction personnel or objects accidentally fall into the safety net 12, the two electric lifting devices 8 will not collide with each other due to the large impact force, thus preventing a staged fall or damage to the electric lifting device 8. This provides a basic guarantee for the stable support of the safety net 12.
[0031] like Figure 2 and Figure 6 As shown, the AI monitoring alarm 22 is installed on the electrically driven lifting device 8 diagonally opposite the safety rope. During operation, the two diagonally opposite AI monitoring alarms 22 face the center of the safety net 12, covering the entire safety net 12 with zero viewing angle error. This avoids blind spots caused by viewing angle issues, ensuring that no fall is missed. It monitors the center of the safety net 12 in real time for any falling activity. If a person falls onto the safety net 12, it dynamically identifies the fall and triggers an alarm via loudspeaker. If an object falls onto the safety net 12, it also alerts the system. This real-time response allows on-site personnel to be aware of the danger immediately, buying valuable time for rescue or handling and reducing losses caused by accidents. Simultaneously, it transmits captured photos and dynamic videos to the backend monitoring unit 27. This allows backend management personnel to intuitively and clearly understand the details of the fall situation, facilitating accurate judgment and decision-making, and providing a reliable basis for subsequent accident analysis and liability determination. Through automated and intelligent monitoring and alarm methods, reliance on manual monitoring is reduced, lowering the risk of accidents going undetected due to human negligence. Meanwhile, its comprehensive monitoring and recording functions help strengthen the management and supervision of on-site safety conditions, promoting more standardized and efficient safety management. The system of this invention deploys AI monitoring and alarm devices diagonally across the safety net, enabling dynamic identification and classification of falling objects (people or objects), and simultaneously uploading event images and videos to the backend system. This design overcomes the limitation of traditional safety nets that lack post-event feedback, enabling real-time response capabilities for safety protection.
[0032] like Figure 7As shown, one end of the impact data transmitter 11 is connected to the hook rope 10 of the electric lifting device 8, and the other end is connected to a corner of the safety net 12. It includes an impact damping spring 25 and a data reading transmitter 26. When a person or object falls onto the safety net 12 and reaches a critical weight, the safety net 12 will compress the impact damping spring 25 to achieve a shock absorption effect. This process effectively buffers the impact force generated by the fall, reducing direct impact damage to the falling person (or object) and the safety net 12 itself, protecting personnel safety and extending the service life of the safety net 12. The presence of the impact damping spring 25 adds a layer of physical protection redundancy to the safety net 12, reducing the risk of damage to the safety net 12 and the electric lifting device 8 due to excessive instantaneous impact force, ensuring the stability of the entire safety protection system. The data reading transmitter 26 will send the recorded data to the controller in real time, and then the controller will aggregate it and send it to the background monitoring unit 27. The data transmission function allows managers to promptly detect abnormal stress conditions on the safety net 12 or the device, facilitating early maintenance and preventing secondary safety issues caused by equipment aging or overload.
[0033] like Figure 8 As shown, the backend monitoring unit 27 can organize the data collected from the impact data transmitter 11 and the AI monitoring alarm 22 into daily, weekly, and monthly reports, and synchronize them with the mobile APP in real time. The system automatically organizes the collected data into daily, weekly, and monthly reports, which not only clearly present key indicators such as the number, type, impact force, and equipment operational stability of fall events within a period, but also helps managers discover patterns of safety hazards through data trend analysis. Multi-dimensional data statistics assist in safety analysis and decision-making. This data provides a scientific basis for formulating targeted safety measures, promoting the transformation of safety management from "passive response" to "proactive prevention." Real-time synchronization of data with the mobile APP breaks the spatial limitations of backend monitoring. On-site managers, rescue personnel, or relevant responsible persons can view real-time alarm information, fall images, impact force data, etc., through their mobile phones at any time, enabling them to grasp the situation on site immediately and quickly dispatch resources.
[0034] like Figure 9 As shown, in another embodiment of the present invention, a method for rapid disassembly, assembly, and monitoring of intelligent safety nets for large-span steel structure roofs is provided, comprising the following steps: S100. Based on the size of the factory and the actual situation, determine the installation distance between the support platforms 20 on both sides of the steel cable circulation transmission mechanism 13 and the length of the steel cable 9. When installing the steel cable 9, the platforms on both sides need to tighten the steel cable 9 so that tension is generated between them. S200. Determine the appropriate size of the safety net 12 according to the length and width of the factory building. Two or more sets of safety nets 12 can be equipped according to the actual situation. When installing the safety net 12, place the safety net 12 on the ground 5. Determine the distance between the electric drive lifting devices 8 according to the width of the safety net 12. S300. Install an electric drive lifting device 8 on the steel cable 9 and fix it by tightening the steel cable clamp 21 with hexagonal bolts. Then, according to the width of the safety net 12, drive the motor to make the steel cable 9 reach the corresponding distance. Then install another electric drive lifting device 8 on the steel cable 9. This is the same for both the front and rear factory buildings, and it must be done simultaneously. S400, drive the steel cable circulation transmission mechanism 13 on both sides to make the electric drive lifting device 8 on both sides reach a certain distance from the support platform 20, then remotely control the motor drive mechanism 6 to make the hooks fall to the ground 5, connect the end of the hook to the impact value transmitter 11, and connect the impact value transmitter 11 to the safety net 12. This is the same for all four hooks. S500, remote-controlled electric drive lifting device 8 raises the hook to the predetermined safety net 12 installation layer. Each component can be combined and deployed according to the actual structure of the plant, supporting the synchronous installation of multiple sets of safety nets 12, and has good modular scalability and on-site adaptability. S600 When a person or object falls onto the safety net 12, the AI monitoring alarm 22 will intelligently identify that there is a person or object on the safety net 12 and send the alarm information to the background monitoring unit 27. The impact value transmitter 11 will also send the maximum impact weight of the person or object falling to the background monitoring unit 27. The S700 and the background monitoring unit 27 can organize the data collected from the impact value transmitter 11 and the AI monitoring alarm 22 into daily, weekly, and monthly reports and synchronize them with the mobile APP in real time. The system of this invention is equipped with a background monitoring unit that can automatically generate daily, weekly, and monthly reports based on data uploaded from field equipment, support accident tracing and safety trend analysis, and synchronize them in real time via the APP, realizing intelligent monitoring of the entire process from on-site perception to remote management. Each component can be combined and deployed according to the actual structure of the plant, supporting the simultaneous installation of multiple safety nets, and has good modular scalability and on-site adaptability.
