Description

Technical Field

[0001] The present invention relates to the technical field of construction site safety management and control, and in particular to a high-altitude operation unhooking alarm safety belt management and control system. Background Art

[0002] During power construction, various environmental factors require workers to perform high-altitude operations. Power construction safety belts are essential for workers working at heights to prevent falls and injuries. These belts, composed of belts, ropes, and metal fittings, are widely used in power maintenance, infrastructure construction, and wiring installations. Traditional safety belts are used voluntarily and in accordance with regulations through employee safety awareness. However, some workers working at heights detach their safety belt hooks for convenience, a serious violation that persists despite repeated bans. Furthermore, accidents can sometimes occur due to lack of consideration or carelessness due to environmental factors. Failure to wear safety belts in a field setting, where inspection is impossible and subsequent tracing is impossible, results in significant safety costs.

[0003] In contrast, the Chinese patent application with publication number CN118506517A proposes an intelligent detection system for safety belt hooks on aerial work platforms. The system can remind aerial workers through a voice alarm module, thereby reducing safety hazards in aerial work.

[0004] Based on the above-mentioned comparative documents and existing technologies, in order to reduce safety hazards, researchers have developed various high-altitude work alarm safety belts, including safety belts with wired alarm circuits, safety belts with sensor-induced alarms, etc. This type of safety belt has a blind spot in supervision. Even if equipped with separate ground supervisors, since most of these safety belt equipment are single-machine operated, although ground supervisors can receive alarm text messages in time, it is difficult to centrally manage and flexibly deploy for situations that require large-scale operations and a relatively large operating range. The labor cost required is relatively high and management is difficult. Summary of the Invention

[0032] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0033] According to one embodiment of the present invention, Figure 1-Figure 5 A high-altitude work unhooking alarm safety belt management and control system includes a backend management system and a unhooking detection system, which are communicatively connected. The unhooking detection system is installed on the safety belt and includes a trigger mechanism 2 located on the safety hook 11. When the lock tongue 12 is unhooked, the main control box 25 in the trigger mechanism 2 sounds an alarm.

[0034] The backend management system includes an alarm receiving module, an electronic map module, a cluster scheduling module, a circle selection alarm module, a terminal speaking module and a storage analysis module.

[0035] The control method of the above-mentioned high-altitude work unhooking alarm safety belt control system includes the following steps:

[0036] Step S1: Perform a signal check of the regional environment before construction to ensure that the system's electronic map module can provide coverage and achieve positioning;

[0037] Step S2: Bind the operator information with the safety belt device number and enter it into the background management system, then establish a communication connection between the background management system and the main control box 25 of the decoupling detection system and check the communication signal;

[0038] Step S3: The terminal manager uses the electronic map module and the cluster scheduling module to divide the work groups according to the regional work range. Each group is equipped with a ground monitoring personnel. The ground monitoring personnel monitor the alarm status of the group through the alarm receiving module. If an alarm signal is received, the terminal shouting module will issue a voice reminder, requiring the operator to use the double hook backup rope and the fence belt alternately to move;

[0039] Step S4: When the operation is completed, the decoupling frequency and safety algorithm storage module performs statistics on the number of alarms and the duration of alarms for each group, and uploads and stores the statistical results that exceed the preset values.

[0040] The specific operation of the control method based on the above-mentioned high-altitude work unhooking alarm safety belt control system is as follows:

[0041] This management and control system is designed in the form of a WeChat public account or mini-program. Ground monitoring personnel bind and enter the equipment into the equipment they manage before operation. When the high-altitude personnel unfasten their safety belts, the ground monitoring personnel will receive an alarm prompt at the same time and remind them through voice calls to use double-hook backup ropes and fence belts alternately to move.

[0042] The system is adaptable to a variety of network combinations, including local area networks, 4G mobile networks, and Wi-Fi networks. Designed using IoT technology, the system features comprehensive perception, network transmission, and intelligent analysis and processing. The data acquisition unit is directly deployed at the front end of the device, eliminating human interference, ensuring data authenticity and validity, and improving the system's resistance to external interference.

[0043] The safety hook 11 of the safety belt is equipped with a trigger box 23. When the safety hook 11 is unhooked, the main control box 25 detects that the trigger box 23 is disconnected and generates an audible and visual alarm. The trigger box 23 and the main control box 25 are connected by a first connecting wire 24 and a second connecting wire 26, or a wireless connection. The trigger box 23 on the lock tongue 12 is provided with a trigger plate 27. When the safety hook 11 and the lock tongue 12 are fully in contact, it is equivalent to an open switch and the alarm circuit is not triggered. When the safety hook 11 and the lock tongue 12 are separated, it is equivalent to a closed switch and the alarm circuit in the main control box 25 is triggered. The alarm signal is transmitted to the terminal system of the ground supervisor and the back-end management personnel, and the system performs alarm reminders and statistical processing.

[0044] The electronic map module is equipped with a map engine to locate and monitor the area where the seat belt equipment is located and the presence of personnel in real time; the cluster dispatch module uses map information to circle and group the closest distances, and the terminal speaking module is used to issue alarms or speak between ground monitoring personnel, back-end management personnel and staff.

[0045] The storage module stores construction personnel information, equipment information, the frequency of unhooking of a single device within a certain period of time, the alarm duration, and the number of unhandled alarms. It analyzes the behavior of the operators, classifies those who have unhandled alarms for more than a certain number of times and those who have worn safety belts for more than a certain cumulative alarm duration, and filters, sorts, and stores the results.

[0046] According to one embodiment of the present invention, Figure 2-Figure 11 A high-altitude work unhooking alarm safety belt control system includes a safety hook 11, a lock tongue 12 and an unlocking buckle 13. The lock tongue 12 and the unlocking buckle 13 are connected to the safety hook 11 through a hinge. A hanging rope ring 14 is provided at the bottom end of the safety hook 11. The hanging rope ring 14 is used to connect the safety belt. A trigger mechanism 2 is embedded in the interior of the safety hook 11. The trigger mechanism 2 includes a main control box 25. The main control box 25 is embedded in the interior of the safety hook 11. One end of the main control box 25 is electrically connected to a first connecting wire 24. The side of the first connecting wire 24 away from the main control box 25 is connected to a trigger box 23. The top of the trigger box 23 is connected to a trigger piece 27. The top of the control box 25 is connected to the feedback plate 21, and the feedback plate 21 is electrically connected to the second connecting wire 26. The top of the second connecting wire 26 is connected to the trigger paddle 28. A reserved groove 22 is defined inside the safety hook 11, and a threading groove 29 is defined inside the lock tongue 12. The main control box 25 and the trigger box 23 are both embedded in the interior of the safety hook 11. The first connecting wire 24 is embedded in the reserved groove 22. The trigger paddle 28 is embedded in the interior of the lock tongue 12. The second connecting wire 26 is embedded in the threading groove 29. The top of the trigger box 23 extends to the outer surface of the safety hook 11 and is linked to the trigger paddle 28 in the lock tongue 12.

[0047] In high-altitude operation scenarios, the safety hook 11 is the core component that connects the safety rope to the fixed hanging point, and its reliability is directly related to the life safety of the operators. However, after long-term use, the contact part between the safety hook 11 and the lock tongue 12 is prone to loose fit due to factors such as wear and corrosion, resulting in a gap between the two. If not inspected or maintained in time, the safety rope may slip out of the gap, causing a fall or object falling accident; therefore, in order to avoid this problem; a main control box 25 and a trigger box 23 are set inside the safety hook 11 and the lock tongue 12. When the trigger paddle 28 set inside the lock tongue 12 and the trigger piece 27 set inside the safety hook 11 are disengaged, an alarm will be issued through the main control box 25. At this time, the alarm device can be used to remind the staff to inspect the hook body to ensure the safety of high-altitude operations;

[0048] The unlocking buckle 13 is provided with a movable groove 34, and the interior of the unlocking buckle 13 is penetrated by a releasing assembly 3, which includes a connecting pin 31, which simultaneously penetrates the movable groove 34 and the interior of the lock tongue 12, and the lock tongue 12 and the unlocking buckle 13 are connected by the connecting pin 31, and the movable groove 34 and the connecting pin 31 maintain a sliding connection. The interior of the unlocking buckle 13 is also provided with an adjusting groove 35, and an adjusting rod 33 is embedded in the adjusting groove 35. The bottom end of the adjusting rod 33 is connected to a supporting spring 32 to further ensure the connection reliability between the safety hook 11 and the lock tongue 12. After a period of time, by adjusting the position of the adjusting rod 33, the distance between the real-time adjusting rod 33 and the connecting pin 31 is farther, so that the pulling force of the supporting spring 32 on the connecting pin 31 is also greater, which makes the safety hook 11 and the lock tongue 12 fit more closely, compensating for the wear gap after long-term use.

[0049] In addition, in order to prevent the rope from escaping from the gap, the locking assembly 4 can be provided to further constrain the position of the lock tongue 12 so that the lock tongue 12 and the safety hook 11 fit more closely. The specific operation is as follows:

[0050] The safety hook 11 is connected to the locking assembly 4 on both sides. The locking assembly 4 includes a locking block 41, which is welded to both sides of the safety hook 11. A guide groove 42 is provided inside the locking block 41. The inner wall of the guide groove 42 is connected to an anti-retraction block 44. A locking rod 46 is embedded in the guide groove 42. The locking rod 46 and the guide groove 42 are slidably connected. A locking opening 45 is provided at the top of the lock tongue 12. The locking opening 45 is adapted to the locking rod 46. The interior of the locking block 41 is provided with an arched portion 48 and a bent portion 49. The arched portion 48 and the bent portion 49 form a 7-shaped guide structure. The upper surface of the arched portion 48 is covered with an auxiliary sheet 47.

[0051] When the rope is inserted between the safety hook 11 and the locking tongue 12, the tight fit between the safety hook 11 and the locking tongue 12 forms a closed loop, which is used to secure the safety rope. A small gap will appear at the contact interface between the safety hook 11 and the locking tongue 12. When the safety rope is subjected to dynamic loads, such as the impact of a fall or horizontal drag, plastic deformation or fiber slippage will occur in a part of the rope, causing the diameter of that part to decrease. At this time, if the width of the gap exceeds the minimum diameter of the rope after deformation, it will cause the rope to escape.

[0052] In contrast, after the safety hook 11 and the lock tongue 12 are fitted together, the locking rod 46 is slid. After the locking rod 46 slides inside the guide groove 42, the locking rod 46 is slid to the bottom end of the guide groove 42. At this time, the locking rod 46 is embedded in the locking opening 45. The interlocking between the locking rod 46 and the locking opening 45 solves the problem of gaps at the connection, thus preventing the rope from escaping from the gap. When the locking rod 46 is embedded in the locking opening 45, the inner side of the locking rod 46 is also tightly fitted to the two side surfaces of the lock tongue 12. The locking rod 46 increases the restriction on the lock tongue 12 and prevents the lock tongue 12 from twisting in the left and right directions.

[0053] When the locking rod 46 slides inside the guide groove 42, the locking rod 46 slides against the surface of the auxiliary piece 47, wherein the movement trajectory of the locking rod 46 inside the guide groove 42 is similar to a 7-shape. When passing the corner of the guide groove 42, the locking rod 46 presses the arched portion 48, causing the arched portion 48 to deform. At this time, the arched portion 48 will be concave downward. When the arched portion 48 is concave, the locking rod 46 can also be pushed through the corner. Finally, the locking rod 46 is pushed along the bent portion 49 to the end of the guide groove 42. This locking rod 46 can also be embedded in the interior of the locking opening 45. During the period when the locking rod 46 is pushed along the bent portion 49, the locking rod 46 is vertically inserted into the locking opening 45 along the bent portion 49.

[0054] Considering that the staff may detach the rope from the gap of the hook body to facilitate their work, however, the small gap is not a completely detached state. Due to the long-term use of the safety hook 11, the surface will be worn to varying degrees, resulting in the fitting surface not being completely fitted. However, the alarm system can only sound an alarm when the safety hook 11 and the lock tongue 12 are completely detached, that is, when the trigger piece 27 and the trigger paddle 28 are completely detached;

[0055] Such illegal operation cannot trigger the alarm device. To avoid such an incident, after the locking opening 45 and the locking rod 46 are buckled, they cannot be disengaged. When the staff wants to release the locking relationship between the locking opening 45 and the locking rod 46, they need to disengage the locking rod 46 from the locking opening 45. Only then will the rope have a chance to escape from the gap between the safety hook 11 and the lock tongue 12. In order to prevent the staff from having such an idea, the anti-return block 44 is provided to change the movement trajectory of the locking rod 46, so that the locking rod 46 cannot move along the path when locked. The specific operation is as follows:

[0056] The locking rod 46 slides to the bottom end along the guide groove 42 and engages with the locking mouth 45. When the locking rod 46 wants to move in the opposite direction, it will be blocked by the anti-return block 44. At this time, the movement of the locking rod 46 causes the bent portion 49 to bend, that is, when the locking rod 46 initially moves, it is in a lateral movement. Once the locking rod 46 moves laterally, it will push the lock tongue 12. At this time, the gap between the lock tongue 12 and the safety hook 11 will become larger. When the gap between the safety hook 11 and the lock tongue 12 becomes larger, once the safety hook 11 and the lock tongue 12 detect the lateral movement, the safety hook 11 and the lock tongue 12 will be completely disengaged, so that the contact surfaces of the trigger piece 27 and the trigger paddle 28 of the two are completely disengaged. At this time, the main control box 25 detects this situation, it will sound an alarm, immediately trigger the sound and light alarm and upload data to the background, forcibly terminating the illegal operation.

[0057] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
