Description

Technical Field

[0001] This utility model belongs to the technical field of railway work safety belt systems, specifically relating to a fall-prevention safety belt with locking function. Background Technology

[0002] In railway electrification line maintenance, tower climbing is a high-risk operation. Workers need to complete tasks such as line inspection and equipment installation at high altitudes, and their safety protection mainly relies on safety belt equipment.

[0003] Currently, the main safety equipment used in the railway industry is the safety belt. This type of safety belt provides protection through the combination of mechanical buckles and hanging rings. Its core relies on the manual operation of the workers to ensure the alternating attachment of the main protective belt and the backup protective rope.

[0004] However, during the process of climbing railway towers, workers need to frequently change their body position and cross crossarms and other structures. Due to the increased pace of operation or distraction, they may engage in the illegal double-unlocking operation of the main safety harness and the backup safety rope at the same time. If they slip or lose their balance at this time, it will directly lead to a fall accident.

[0005] Although existing improved safety belts have added mechanical interlocking devices, they are prone to jamming and failure under the strong electromagnetic environment of railways and daily mechanical wear, which is insufficient to meet the safety protection requirements for high-altitude operations on electrified railway lines.

The locking mechanism has a cavity, and the first locking contact pad and the first locking rod are both located in the cavity. The first locking contact pad is located directly below the first locking groove. When the first locking rod slides along the first slide rail to the first locking groove, the first locking tooth abuts against the first locking contact pad.

[0016] Furthermore, the first and second electric signal transceivers have the same structure.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the coordinated action of the first intelligent latch, the second intelligent latch, and the electric signal transceiver, the magnetic induction sensor monitors the engagement status of the latch and the second D-shaped hanging ring in real time, and the electric actuator realizes the automatic locking and unlocking of the latch. Secondly, the control logic combining magnetic field induction and electric actuation avoids the problem of traditional mechanical interlocking devices being prone to jamming and failure under strong electromagnetic environment and daily mechanical wear, ensuring that status signals and control commands can still be stably transmitted in complex electromagnetic environment, and ensuring the reliable operation of the locking function.

[0018] 2. The first and second D-type hooks are symmetrically distributed on the main waist belt of the safety belt, which makes it easy for workers to connect the main safety belt and the backup safety rope to both sides of their body, avoiding imbalance of body force caused by one-sided attachment; the signal monitoring alarm receiver is located between the two hooks, which will not interfere with the connection operation of the buckle and the hook, and can make the signal receiving and transmitting sensor receive the signals of the smart buckles on both sides evenly, reducing signal transmission blind spots and improving the accuracy of status monitoring.

[0019] 3. The two ends of the protective belt body are connected to the first screw fastener and the first smart fastener through the first triangular hanging ring and the second triangular hanging ring, respectively. The structural characteristics of the triangular hanging ring can evenly distribute the force to the protective belt body, avoiding belt tearing or loosening caused by single-point force. At the same time, the first screw fastener and the first D-shaped hanging ring on the main waist belt are mechanically connected, which is tight and not easy to accidentally come off, ensuring the reliability of the connection between the main protective belt and the main waist belt.

[0020] 4. The first robotic arm and the second robotic arm, which are embedded at the top of the first push shaft, form a double-sided abutment with the inner wall of the first smart lock through the first locking pad and the second locking pad. Compared with the single-sided locking structure, it can withstand greater lateral and longitudinal impact forces and avoid the lock from loosening due to the shaking of the operator's body or accidental force.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings: See Figures 1-22 This utility model embodiment provides a fall protection safety belt with locking function, including: a main waist belt 1, a main protective belt 2, a backup protective rope 3, and a fall protection belt 4. The main protective belt 2 and the backup protective rope 3 are detachably connected to the main waist belt 1, and the fall protection belt 4 is movably connected to the main protective belt 2 and the backup protective rope 3. The main waist belt 1 is equipped with a signal monitoring alarm receiver 13 and a second D-shaped hanging ring 124. Specifically, the second D-shaped hanging ring 124 is a magnetic hanging ring.

[0030] The main safety belt 2 is equipped with a first smart buckle 23 and a first electric signal transceiver 24, and the backup safety belt rope 3 is equipped with a second smart buckle 33 and a second electric signal transceiver 34. Both the first electric signal transceiver 24 and the second electric signal transceiver 34 are communicatively connected to the signal monitoring and alarm receiver 13, and both the first electric signal transceiver 24 and the second electric signal transceiver 34 are equipped with magnetic induction sensors for sensing the magnetic field signal of the second D-type hanging ring 124. Among them, both the first smart buckle 23 and the second smart buckle 33 are equipped with electric actuators, which are electrically connected to the first electric signal transceiver 24 and the second electric signal transceiver 34. The electric actuators are used to lock or unlock the first smart buckle 23 and the second smart buckle 33 under the control of the first electric signal transceiver 24 and the second electric signal transceiver 34.

[0031] Traditional safety harnesses rely on workers manually alternating between the main safety harness 2 and the backup safety rope 3. During high-frequency movements such as changing body positions and crossing crossbeams while climbing poles, the tension and distraction can easily cause both to unlock simultaneously, creating a fatal safety vulnerability. This new safety harness, however, utilizes the coordinated operation of the first smart buckle 23, the second smart buckle 33, the first electric signal transceiver 24, and the second electric signal transceiver 34 to create a protective mechanism that prevents both from unlocking under unauthorized conditions. Specifically, when only the first smart buckle 23 is engaged with the second D-shaped hook 124, the first electric signal transceiver 24 automatically sends a locking signal, locking the first smart buckle 23 via an electric actuator to prevent accidental locking. Only when both the main and backup smart buckles are engaged are they simultaneously unlockable, ensuring that at least one protection is always effective when switching protection points. This forced interlocking design completely eliminates reliance on standardized manual operation, fundamentally preventing falls caused by human error. Furthermore, the surrounding areas of electrified railway lines are subject to complex and strong electromagnetic interference. Combined with the mechanical wear caused by frequent use of seat belts, traditional improved seat belt mechanical interlocking devices are susceptible to jamming and failure due to electromagnetic influences and mechanical wear over long-term use, leading to malfunctions and loss of protective function. This new seat belt solves the reliability problem in electromagnetic environments through an optimized combination of magnetic induction sensing and electric actuators. On one hand, the magnetic induction sensors built into the first and second electric signal transceivers 24 and 34 are specifically designed for the magnetic field signal of the second D-type hook, possessing signal recognition capabilities resistant to electromagnetic interference and accurately determining the locking status in strong electromagnetic environments. On the other hand, the electric actuator adopts a low electromagnetic sensitivity drive structure, achieving stable control through the first and second transmission buses 25 and 35, avoiding jamming problems caused by electromagnetic adsorption, component magnetization, and mechanical wear in the mechanical interlocking device. This ensures that the seat belt's protective function remains stable and effective in the special environment of electrified railway lines, breaking through the environmental adaptability bottleneck of traditional equipment. Furthermore, such as Figure 1As shown, the main lap belt 1 of the seat belt includes a lap liner 11, which includes a lap pad 111, a support and limiting strap 112, a lap belt 12, a lap belt locking pin 121, a main lap belt 122, a first D-shaped loop 123, a second D-shaped loop 124, and a signal monitoring and alarm receiver 13. The lap pad 111 has multiple support and limiting straps 112 connected to each other via the lap belt 12. The lap belt 12 includes a main lap belt 122, with a lap belt locking pin 121 connected to the end of the main lap belt 122. The first D-shaped loop 123 and the second D-shaped loop 124 are symmetrically arranged on the main lap belt 122. The signal monitoring and alarm receiver 13 is located between the first D-shaped loop 123 and the second D-shaped loop 124. In the signal monitoring and alarm receiver 13, there are a speaker 131, a power supply compartment 132, a signal receiving and transmitting sensor 133, a first smart lock status display 134, and a second smart lock status display 135. The speaker 131, the signal receiving and transmitting sensor 133, the first smart lock status display 134, and the second smart lock status display 135 are all electrically connected to the power supply compartment 132. The speaker 131 is used to announce the locking or unlocking status of the first smart lock 23 and the second smart lock 33. The first smart lock status display 134 and the second smart lock status display 135 are used to display the status of the first smart lock 23 and the second smart lock 33, respectively.

[0032] The main waist belt 1 of the safety belt effectively balances wearing comfort and structural stability through the waist pad 11: Firstly, the waist pad 111, as a component that comes into direct contact with the human body, can cushion the pressure of the main waist belt 122 on the waist; secondly, the multiple support and limiting straps 112 set on the waist pad 111 can evenly distribute the tension to both sides of the waist and the back, preventing the waist belt 12 from shifting or slipping due to changes in body position during operation; at the same time, through the connection with the waist belt 12, the overall support strength of the main waist belt 1 of the safety belt is further enhanced. The signal monitoring and alarm receiver 13 is located between the first D-type hanging ring 123 and the second D-type hanging ring 124. On the one hand, when the staff is not climbing the pole, the monitoring personnel can use the signal monitoring and alarm receiver 13 to confirm the safety status. On the other hand, it avoids collision damage to the signal monitoring and alarm receiver 13 during the hanging ring operation. At the same time, the signal monitoring and alarm receiver 13 is installed close to the upper middle part of the body, and the broadcast sound emitted by the speaker 131 on the signal monitoring and alarm receiver 13 can be transmitted to the ears of the workers more clearly, effectively overcoming the interference of wind noise and equipment operating noise at the pole operation site.

[0033] In this design, the main safety belt 2 includes a main body 21, a first threaded buckle 22, a first smart buckle 23, a first electric signal transceiver 24, and a first transmission bus 25. An extension buckle 212 is located in the middle of the main body 21, the first threaded buckle 22 is located at one end of the main body 21, and the first smart buckle 23 is located at the other end of the main body 21. The first electric signal transceiver 24 is located at the end of the main body 21 near the first smart buckle 23, and the first transmission bus 25 is connected to the first smart buckle 23. The main body 21 also includes a first triangular hanging ring 213 and a second triangular hanging ring 214. One end of the triangular hanging ring 213 is connected to one end of the protective belt body 21, and the other end is connected to the first threaded buckle 22; one end of the second triangular hanging ring 214 is connected to the other end of the protective body 21, and the other end is connected to the first smart buckle 23; the first threaded buckle 22 is engaged with the first D-shaped hanging ring 123; the first electric signal transceiver 24 includes a first battery compartment 241, a first switch button 242 and a first status indicator light 243, the first switch button 242 and the first status indicator light 243 are connected to the first battery compartment 241; the electric actuator includes a first electric actuator 26, the first electric actuator 26 is disposed in the first smart buckle 23.

[0034] The two ends of the protective belt body 21 are connected to the first threaded buckle 22 and the first smart buckle 23 respectively through the first triangular hanging ring 213 and the second triangular hanging ring 214. The structural characteristics of the first triangular hanging ring 213 and the second triangular hanging ring 214 can evenly distribute the tensile force to the three stress points of the first triangular hanging ring 213 and the second triangular hanging ring 214, avoiding the risk of breakage caused by excessive stress at a single point. Especially in the event of a sudden fall, it can withstand a greater impact load and has better tensile performance than the traditional straight hanging ring. Secondly, the first threaded buckle 22 and the first D-shaped hanging ring 123 of the main waist belt 1 of the safety belt adopt a threaded connection method, which can effectively prevent accidental loosening caused by vibration and pulling during operation, and solve the problem of loose fastening caused by wear and deformation of the traditional buckle connection. The first electric signal transceiver 24 of the main protective belt 2 is directly connected to the first electric actuator 26 inside the first smart buckle 23 via the first transmission bus 25. It has low signal transmission delay and strong anti-interference ability, and can quickly respond to the engagement status of the second D-type hanging ring 124 and drive the electric actuator to complete the locking or unlocking action of the first smart buckle 23, ensuring that the locking control response speed meets the real-time protection requirements of high-altitude operations. Secondly, the first status indicator light 243 integrated in the first electric signal transceiver 24 can intuitively reflect the working status. The operator can quickly judge whether the intelligent control function is normal by the indicator light, avoiding protection failure due to equipment failure. Thirdly, the first battery compartment 241 provides power support for the electric signal transceiver, forming a dual independent power supply with the power supply compartment 132 of the signal monitoring alarm receiver 13 on the main waist belt 1. Furthermore, such as Figure 7 As shown, the first smart latch 23 includes a first smart latch tongue 231, a first smart latch pin 232, a first smart latch safety 233, a first bus outlet 234, and a smart latch main ring 235. One end of the smart latch main ring 235 is connected to the first smart latch safety 233. The first bus outlet 234 is opened on the first smart latch safety 233. The first smart latch pin 232 is disposed in the first smart latch safety 233. The first smart latch tongue 231 is disposed at the other end of the smart latch main ring 235. The first electric actuator 26 includes a first small electric cylinder body 2301, a first push shaft 2302, and a first battery cell driver 2303. The first push shaft 230... 2. A first mechanical arm 2309 and a second mechanical arm 2310 are embedded on the top of the first push shaft 2302, and the ends of the first mechanical arm 2309 and the second mechanical arm 2310 away from the first push shaft 2302 are respectively provided with a first locking pad 2311 and a second locking pad 2312; the first intelligent locking post 232 is provided with a first limiting port 2321 and a second limiting port 2322, and the first mechanical arm 2309 and the second mechanical arm 2310 are respectively located in the first limiting port 2321 and the second limiting port 2322; the first battery cell driver 2303 is connected to the first electric signal transceiver 24 through the first transmission bus 25. The connection is used to receive instructions from the first electric signal transceiver 24 and control the reciprocating motion of the first push shaft 2302 to drive the first robotic arm 2309 and the second robotic arm 2310 to move, so that the first locking pad 2311 and the second locking pad 2312 abut against or disengage from the inner wall of the first smart lock safety 233, so that the first smart lock safety 233 is locked or unlocked.

[0035] The backup safety rope 3 includes a backup safety rope body 31, a second threaded buckle 32, a second smart buckle 33, a second electric signal transceiver 34, and a second transmission bus 35. The backup safety rope body 31 is composed of a safety rope 311, a first round rubber pad 312, and a second round rubber pad 313. The first round rubber pad 312 is located at one end of the safety rope 311, and the second round rubber pad 313 is located at the other end of the safety rope 311. The second threaded buckle 32 is connected to the first round rubber pad 312, and the second smart buckle 33 is connected to the second... A round rubber pad 313 is connected, and a second electric signal transceiver 34 is set on the protective rope 311 and close to the second smart lock 33. The second electric signal transceiver 34 is connected to the second transmission bus 35. The second threaded lock 32 is movably connected to the first D-shaped hanging ring 123. The second electric signal transceiver 34 includes a second battery compartment 341, a second switch button 342 and a second status indicator light 343. The second switch button 342 and the second status indicator light 343 are electrically connected to the second battery compartment 341.

[0036] The fall arrestor belt 4 includes a fabric belt 40, a reversing buckle 41, a third threaded buckle 42, a fourth threaded buckle 43, at least one self-retracting telescopic device, a first connecting buckle 46, a second connecting buckle 47, a third triangular hanging ring 48, and a fourth triangular hanging ring 49; the fabric belt 40 includes a first fabric belt 401, a second fabric belt 402, a third fabric belt 403, and a fourth fabric belt 404, which are connected in sequence; the reversing buckle 41 is disposed between the second fabric belt 402 and the third fabric belt to reverse the direction of the third fabric belt; the third threaded buckle 42 is disposed on the first fabric belt 401, and the fourth threaded buckle 43 is disposed on the fourth fabric belt 404; the self-retracting telescopic device is disposed on the fabric belt 40; wherein, the reversing buckle 41 is used to adjust the reversal of the third fabric belt 403.

[0037] The self-retracting telescopic device includes a first self-retracting telescopic device 44, which includes a first cam self-locking device 440, a first telescopic belt 441, and a locking mechanism. The first cam self-locking device 440 and the first telescopic belt 441... The locking mechanism includes a first locking contact pad 442, a first locking rod 443, a first locking spring 444, a first steering lock 445, a first locking slider 446, a first slide rail 447, a first locking groove 448, and a first locking tooth 449. The locking mechanism has a cavity in which the first locking contact pad 442 and the first locking rod 443 are located. The first locking contact pad 442 is located directly below the first locking groove 448. When the first locking rod 443 slides along the first slide rail 447 to the first locking groove 448, the first locking tooth 449 abuts against the first locking contact pad 442. After the first steering self-locking device 445 is pressed down, the first locking tooth 449 is firmly pressed against the first locking contact pad 442. The end of the first locking lever 443 is connected to a first locking spring 444, the top of the first locking spring 444 is connected to a first steering lock 445, and the first steering lock 445 is connected to a first locking slider 446. The first locking groove 448 is disposed on the first slide rail 447 and located above the first locking rod 443. The first locking slider 446 is slidably connected to the first slide rail 447 and located above the first locking rod 443. The first locking slider 446 is slidably connected to the first slide rail 447. The first locking tooth 449 is connected to the first locking rod 443 and located on one side of the first locking groove 448. The first cam self-locking device 440 is used to fix the first telescopic belt 441 at a preset length. The first cam self-locking device 440 includes a first coil spring 4401, a first torque connecting rod 4402, a first eccentric cam 4403, and a first clamping ring 4404. Figure 18As shown, the first eccentric cam 4403 is connected to the first coil spring 4401 via the first torsion link 4402. The first eccentric cam 4403 and the first torsion link 4402 are integrated through the first clamping ring 4404. It is noteworthy that although integrated, the connection between the first eccentric cam 4403 and the first torsion link 4402 is movable, allowing for a certain degree of freedom of movement. When the first telescopic belt 441 is slowly and uniformly pulled, it drives the first torsion link 4402 and the first coil springs 4401 and the first eccentric cam 4403 to rotate uniformly in the same direction. However... Once a rapid, forceful pull (simulating a high fall) causes the first torque link 4402 to rotate rapidly, the first eccentric cam 4403 is thrown out under the action of centrifugal force, and its teeth are locked in the groove 4405 of the outer ring cam. (It is worth noting that the activity margin described here refers to the groove 4405 of the cam, which means that the eccentric cam has a certain amount of activity space. When the torque link rotates rapidly, it will reach a certain speed under the action of centrifugal force, which is similar to being thrown out. Being thrown out just forms a meshing and locking situation with the groove 4405 of the cam.) The teeth and the groove form a meshing and locking relationship.

[0038] Specifically, the first steering lock 445 has a built-in micro-spring mechanism; when the first locking slider 446 slides to the position of the first locking groove 448, it is locked by the first steering lock 445, so that the first locking tooth 449 on the first locking rod 443 presses the first telescopic band 441 against the first locking contact pad 442. When the first smart latch 23 is attached to the second D-shaped hanging ring 124, the first electric signal transceiver 24 sends a locking signal to control the electric actuator of the first smart latch 23 to operate, thereby locking the first smart latch safety 233. When both the first smart latch 23 and the second smart latch 33 are attached to the second D-shaped hanging ring 124, the first electric signal transceiver 24 sends an unlocking signal to control the electric actuator of the first smart latch 23 to reset, thereby unlocking the first smart latch safety 233, and the second smart latch 33 is simultaneously in the unlocked state. When the first smart latch 23 is removed, the second electric signal transceiver 34 sends a locking signal to control the electric actuator of the second smart latch 33 to operate, thereby locking the second smart latch safety 333. The first electric signal transceiver 24 and the second electric signal transceiver 34 have the same structure.

[0039] In practical applications, such as Figures 1-29 As shown, the first threaded lock 22 is composed of a threaded lock main ring 221, a threaded lock tongue 222, a spring-loaded latch post 223, a threaded safety 224, a lower pin 225, and an upper pin 226; wherein, the threaded lock is an existing product, and this patent does not involve any innovative improvement to it.

[0040] When the first smart latch 23 is in the open position, a first electric actuator 26 is installed in the first smart latch post 232 on the first smart latch 23, and the main body of the first electric actuator 26 is snapped into the first smart latch post 232; the first electric actuator 26 is composed of a first small electric cylinder body 2301, a first push shaft 2302, and a first battery driver 2303; wherein, the first small electric cylinder body 2301 has the first push shaft 2302 built in, and the first push shaft 2302 can reciprocate along the diameter direction of the first small electric cylinder body 2301 under electric drive.

[0041] The top of the first push shaft 2302 is firmly fitted with a first robotic arm 2309 and a second robotic arm 2310. The first robotic arm 2309 and the second robotic arm 2310 are respectively connected to the first sleeve 2306 through a first connector 2307 and a second connector 2308. The first sleeve 2306 is fixed to the top of the first push shaft 2302. The first smart locking post 232 is provided with a first limiting port 2321 and a second limiting port 2322. The first robotic arm 2309 and the second robotic arm 2310 are respectively located in the first limiting port 2321 and the second limiting port 2322 and reciprocate according to the signal command. On the first robotic arm 2309 and the second robotic arm 2310, the ends away from the connecting pins are respectively equipped with a first locking pad 2311 and a second locking pad 2312. The first robotic arm 2309 and the second robotic arm 2310 remain suspended under the action of the first connecting pin 2307 and the second connecting pin 2308, and do not come into contact with other components in the first smart lock post 232 and the smart lock safety 233.

[0042] The first cell driver 2303 is installed at the other end of the first push shaft 2302 away from the first sleeve 2306. The first cell driver 2303 is used to control the reciprocating motion of the first push shaft 2302. The lower part of the first cell driver 2303 has a first lead terminal 2304 and a second lead terminal 2305. A first lead is installed on the first lead terminal 2304 and a second lead is installed on the second lead terminal 2305. The first lead is a power line and the second lead is a signal transmission line.

[0043] The first lead and the second lead are wrapped and wrapped to form a first conductive bus 25. The first conductive bus 25 is led from the first cell driver 2303 end through the first through hole 2323 on the first smart latch post 232, and then through the first bus outlet 234 on the first smart latch safety 233 to the first electric signal transceiver 24.

[0044] The first electric signal transceiver 24 integrates a magnetic field signal sensor. The other end of the first conductive bus 25 is connected to the first electric signal transceiver 24. The first battery compartment 241, the first switch button 242, and the first status indicator light 243 are components on the first electric signal transceiver 24. The first electric signal transceiver 24 integrates a chip board with a magnetic induction sensor. This part is existing technology and does not involve any innovation or improvement in its signal communication, sensing, or other principles.

[0045] When the first smart lock 23 is attached to the second D-shaped hanging ring 124, pressing the first switch button 242 powers it on. When the magnetic induction sensor in the first electric signal transceiver 24 receives the magnetic field signal emitted by the magnetic second D-shaped hanging ring 124, the magnetic induction sensor sends a locking signal.

[0046] The mechanisms by which the two mutually interlocking mechanisms prevent double solutions are as follows: The main components involved are signal monitoring and alarm receiver 13, first smart lock 23, first electric signal transceiver 24, first transmission bus 25, second smart lock 33, second electric signal transceiver 34, and second transmission bus 35.

[0047] The first electric signal transceiver 24 and the second electric signal transceiver 34 are equipped with chips designed to control their operating logic. During the combined use of the smart seat belt, the signal monitoring alarm receiver 13 is in operation. At this time, when the first smart buckle 23 is not yet attached to the magnetic second D-shaped hanging ring 124, the first switch button 242 on the first electric signal transceiver 24 is not activated. Similarly, the second switch button 342 on the second electric signal transceiver 34 connected to the second smart buckle 33 is also not activated.

[0048] At this point, the worker fastens the main waist belt 1 around their waist, and attaches the first buckle 22 on the main safety belt 2 and the second buckle 32 on the backup safety rope 3 to the first D-ring 123 on the main waist belt 1. (To facilitate explaining the principle of double unhooking, the third buckle 42 and the fourth buckle 43 on the fall arrestor 4 can be temporarily omitted from this part).

[0049] When climbing power poles, first open the first smart buckle safety 233 on the main protective belt 2 of the safety belt and attach it to the magnetic second D-shaped hanging ring 124. Then press the first switch button 242 on the first electric signal transceiver 24. After receiving the magnetic field signal emitted by the magnetic second D-shaped hanging ring 124, the magnetic induction sensor integrated in the first electric signal transceiver 24 sends a locking signal through the logic chip via the first conduction bus 25.

[0050] After receiving the locking signal, the first cell driver 2303 controls the first push shaft 2302 in the first electric actuator 26 to move upward. When the first robotic arm 2309 and the second robotic arm 2310 respectively abut against the upper part of the first limit port 2321 and the second limit port 2322, the first push shaft 2302 stops moving. The first locking pad 2311 and the second locking pad 2312 abut against the inner wall of the first smart lock safety 233, so that the first smart lock safety 233 is locked and cannot be twisted at will, thereby achieving the purpose of locking upon receiving the locking signal.

[0051] At this time, the signal monitoring alarm receiver 13 receives the first smart lock safety 233 locked signal from the first electric signal transceiver 24, the first status indicator light 243 lights up, and the speaker 131 broadcasts the first smart lock locked voice to remind the operator.

[0052] Subsequently, the second smart buckle 333 on the safety belt backup rope 3 is attached to the magnetic second D-shaped loop 124. This activates the second switch button 342 on the second electric signal transceiver 34 connected to the second smart buckle 33. After the magnetic induction sensor integrated in the second electric signal transceiver 34 receives the magnetic field signal emitted by the magnetic second D-shaped loop 124, the signal monitoring alarm receiver 13 receives a signal that both the first smart buckle 23 and the second smart buckle 33 are attached. The first electric signal transceiver 24 then sends an unlocking signal, which is transmitted through the logic chip... The first transmission bus 25 sends an unlocking signal. After receiving the unlocking signal, the first cell driver 2303 controls the first push shaft 2302 in the first electric actuator 26 to move downwards and reset. The first robotic arm 2309 and the second robotic arm 2310 return to their original positions from the first limit port 2321 and the second limit port 2322, respectively. The first push shaft 2302 is reset, and the first locking pad 2311 and the second locking pad 2312 are also separated from the inner wall of the first smart lock safety 233, so that the first smart lock safety 233 can be twisted at will, thereby achieving unlocking upon receiving the unlocking signal.

[0053] At this time, the signal monitoring alarm receiver 13 receives the signal that the first smart lock safety 233 has been unlocked from the first electric signal transceiver 24, the first status indicator light 243 goes out, the first smart lock status display 134 on the signal monitoring alarm receiver 13 goes out, and the speaker 131 broadcasts the voice message that the first smart lock has been unlocked to remind the operator.

[0054] At this time, the signal monitoring and alarm receiver 13, the first electric signal transceiver 24, and the second electric signal transceiver 34 are all powered on, and the signal monitoring and alarm receiver 13 is connected to the first electric signal transceiver 24 and the second electric signal transceiver 34.

[0055] When both the first smart latch 23 and the second smart latch 33 are attached to the magnetic second D-shaped hanging ring 124, the first smart latch status display 134 and the second smart latch status display 135 on the signal monitoring alarm receiver 13 are both off, the first smart latch safety 233 and the second smart latch safety 333 are both unlocked, and similarly, the first status indicator light 243 and the second status indicator light 343 are also off.

[0056] When the first smart lock safety 233 is turned, the first smart lock 23 is removed from the magnetic second D-shaped hanging ring 124. The magnetic field signal emitted by the magnetic second D-shaped hanging ring 124, received by the magnetic induction sensor integrated in the first electric signal transceiver 24, weakens. The second electric signal transceiver 34 immediately sends a locking signal through the logic chip and the second conduction bus 35. After receiving the locking signal, the second battery driver 3303 controls the second push shaft 3302 in the second electric actuator 36 to move upward. When the third robotic arm 3309 and the fourth robotic arm 3310 abut against the upper part of the third limit port 3321 and the fourth limit port 3322 respectively, the second push shaft 3302 stops moving. The third locking pad 3311 and the fourth locking pad 3312 abut against the inner wall of the second smart lock safety 333, making the second smart lock safety 333 locked and unable to be turned at will, thereby achieving the purpose of locking upon receiving the locking signal.

[0057] At this time, the signal monitoring alarm receiver 13 receives the second smart latch safety 333 locked signal from the second electric signal transceiver 34, the second status indicator 343 lights up, the second smart latch status display 135 on the signal monitoring alarm receiver 13 lights up, and the speaker 131 broadcasts the second smart latch locked voice to remind the operator.

[0058] This chip signal logic system aims to prevent the main safety belt 2 and the backup safety rope 3 from being unfastened simultaneously during operation. When both the main safety belt 2 and the backup safety rope 3 are secured, for ease of operation, both the first smart buckle safety 233 and the second smart buckle safety 333 are unlocked. The first smart buckle status display 134 and the second smart buckle status display 135 on the signal monitoring and alarm receiver 13 are both off. Similarly, the first status indicator light 243 and the second status indicator light 343 are also off.

[0059] In special circumstances, the first switch button 242 on the first electric signal transceiver 24 and the second switch button 342 on the second electric signal transceiver 34 can be manually turned off simultaneously to de-energize the electric actuator, so that the main safety belt 2 and the backup safety rope 3 of the safety belt can be used as ordinary safety belts.

[0060] Upon receiving a locking signal command, the first electric actuator 26 inside the first smart lock 23 begins to operate. After receiving the operation signal, the first battery driver 2303 drives the top of the first push shaft 2302 to extend upwards. When the first robotic arm 2309 and the second robotic arm 2310 respectively abut against the upper part of the first limit port 2321 and the second limit port 2322, the first push shaft 2302 stops operating. The first locking pad 2311 and the second locking pad 2312 abut against the inner wall of the first smart lock safety 233, making the first smart lock safety 233 locked and unable to be twisted at will, thereby achieving the purpose of locking upon receiving a signal and unlocking automatically upon losing a signal.

[0061] like Figure 13 As shown, this is a schematic diagram of the position of the first locking pad 2311 and the second locking pad 2312 when the first electric actuator 26 of the first smart lock 23 is not activated. The first robotic arm 2309 and the second robotic arm 2310 are in this position when they have not been activated. The first smart lock pin 232 and the first smart lock safety 233 are both located in the position shown in the diagram.

[0062] like Figure 14 As shown, this is a schematic diagram of the position of the first locking pad 2311 and the second locking pad 2312 after the first electric actuator 26 of the first smart lock 23 is activated. The first robotic arm 2309 and the second robotic arm 2310 are in this position after the activation. The first smart lock pin 232 and the first smart lock safety 233 are both in the position shown in the diagram and remain unchanged. After the first electric actuator 26 of the first smart lock 23 is activated, the first locking pad 2311 and the second locking pad 2312 abut against the inner wall of the first smart lock safety 233 to achieve the locking function.

[0063] like Figure 5 As shown, the signal monitoring alarm receiver 13 consists of a speaker 131, a power supply compartment 132, a signal receiving and transmitting sensor 133, a first smart lock status display 134, a second smart lock status display 135, and a USB-C charging interface 136.

[0064] like Figure 16 As shown, taking the first self-retracting telescopic device 44 as an example, it is mainly composed of a first cam self-locking device 440, a first telescopic belt 441, a first locking contact pad 442, a first locking rod 443, a first locking spring 444, a first steering lock 445, a first locking slider 446, a first slide rail 447, a first locking groove 448, and a first locking tooth 449.

[0065] Taking the first self-retracting telescopic device 44 as an example, the first telescopic belt 441 is tightly nested and wrapped around the first torsion link 4402 on the first cam self-locking device 440. During the slow pulling process of the first telescopic belt 441, the first torsion link 4402 rotates with the first telescopic belt 441, and at the same time drives the first eccentric cam 4403 and the first coil spring 4401 connected at both ends of the first torsion link 4402 to rotate in the same direction. The first eccentric cam 4403 is movably connected to one end of the first torsion link 4402 through the first clamping ring 4404, and the first coil spring 4401 is firmly embedded in the other end of the first torsion link 4402, which is different from the first eccentric cam 4403.

[0066] The first eccentric cam 4403 has irregularly shaped protruding teeth, and there is a certain space margin between the first eccentric cam 4403 and the first clamping ring 4404. The purpose is that when the first torsion link 4402 is pulled quickly, the first eccentric cam 4403 is thrown out under the action of centrifugal force and the protruding teeth are engaged in the tooth groove 4405 of the cam wheel, forming a meshing relationship. At this time, as the first eccentric cam 4403 is locked, the first torsion link 4402 and the first coil spring 4401 also stop rotating, and the first telescopic belt 441 is no longer stretched, forming a locking effect.

[0067] This locking effect is a backup safety design for unexpected emergencies, namely, the failure of the first self-retracting telescopic device 44. Under normal use, as the first telescopic belt 441 is slowly pulled out, the first torsion link 4402 rotates with the first telescopic belt 441, and at the same time drives the first torsion link 4402 and the first eccentric cam 4403 and the first coil spring 4401 connected at both ends to rotate in the same direction. At this time, the first coil spring 4401 continuously winds and tightens around the engagement point with the first torsion link 4402 during rotation, storing a certain amount of elastic potential energy.

[0068] During the retraction process of the first telescopic belt 441, the first coil spring 4401 needs to return to its original untightened state and release the stored elastic potential energy, thereby achieving the purpose of self-retraction of the first telescopic belt 441.

[0069] This utility model does not involve any change to the basic working principle. However, during normal operation, the first self-retracting telescopic device 44 without a locking mechanism will adaptively adjust itself as the operator's body position changes. This is suitable for work situations where the body position changes frequently. However, when working at heights, it is not desirable for the length of the first telescopic belt 441 on the first self-retracting telescopic device 44 to change at any time. It is necessary for the length of the first telescopic belt 441 to be maintained at a fixed state. If working in a fixed position, the operator's body needs to lean back. At this time, a stable triangular state is formed between the contact point between the safety belt and the pole, the support point of the waist after leaning back, and the foot buckle. If the telescopic belt is not fixed, there will always be a pulling force, making the person lean back incompletely and unstable.

[0070] Therefore, a locking mechanism is introduced to meet the different needs in different operating scenarios. This locking mechanism is as follows: Figure 18 As shown, it mainly consists of a first locking contact pad 442, a first locking rod 443, a first locking spring 444, a first steering lock 445, a first locking slider 446, a first slide rail 447, a first locking groove 448, and a first locking tooth 449. Its working principle is to make the first locking tooth 449 on the first locking rod 443 press the first telescopic belt 441 tightly against the first locking contact pad 442. At this time, the first telescopic belt 441 is in a relatively stable state, cannot be pulled out, and will not retract on its own.

[0071] One end of the first locking lever 443 is provided with a first locking tooth 449, and the other end is connected to the first steering lock 445 through a first locking spring 444. The first locking spring 444 is located inside the first locking lever 443. The first steering lock 445 is sleeved with a first locking slider 446. The first locking slider 446 can rotate freely outside the first steering lock 445. The working principle of the first steering lock 445 is the existing technology, with a built-in micro-spring mechanism, which aims to achieve the purpose of locking with one press and unlocking with two presses.

[0072] During use, the operator manually slides the first locking slider 446 along the first slide rail 447. During the sliding process, the first locking slider 446 drives the first steering lock 445, the first locking spring 444, the first locking rod 443, the first locking tooth 449 and other components to move synchronously. When it reaches the position of the first locking groove 448, the lower first locking tooth 449 presses the first telescopic belt 441 tightly against the first locking contact pad 442. At this time, the first telescopic belt 441 is in a relatively stable state.

[0073] When the first locking groove 448 is reached, the first locking slider 446 is rotated so that it is aligned with the first locking groove 448. Press it with your finger, and it will be locked under the action of the first locking spring 444 and the first steering lock 445, so that the first locking slider 446 is properly inserted into the reserved first locking groove 448. At this time, the design of the first locking groove 448 has an anti-accidental touch function, which will not cause the first locking slider 446 to slide arbitrarily due to accidental touch. After use, press the first locking slider 446 located in the first locking groove 448 again to unlock it, so that the first locking slider 446 is in an operable sliding state again.

[0074] like Figure 19 As shown, during the sliding of the first locking slider 446 along the first slide rail 447, when the first locking slider 446 reaches the position directly opposite the first locking groove 448, the first locking slider 446 is rotated by the first steering lock 445 so that the first locking slider 446 can be placed in the first locking groove 448, thereby achieving the function of locking and preventing accidental contact.

[0075] like Figure 21 As shown, the first locking tooth 449 presses the first telescopic belt 441 tightly against the first locking contact pad 442, at which point the first telescopic belt 441 is in a relatively stable state.

[0076] like Figure 22 As shown, this is a simplified diagram illustrating the use of the fall arrestor belt with four side posts. The reversing buckle 41 only involves contact with the third fabric belt 403, and their corresponding relationship will be described below. Specifically, the third fabric belt 403 is inserted through the reversing notch 415 of the reversing buckle 41, so that the third fabric belt 403 fits against the roller 413. The roller 413 is sleeved on the roller post 414, and the roller 413 can rotate flexibly on the roller post 414. The main function of the roller 413 is to make the third fabric belt 403 smooth when pulled and adjusted. The first reversing connection port 411 is connected to the second fabric belt 402, and the second reversing connection port 412 is connected to the third fabric belt 403.

[0077] like Figure 22 As shown, the fall arrestor belt 4 includes a fabric belt 40, which is composed of a first fabric belt 401, a second fabric belt 402, a third fabric belt 403, and a fourth fabric belt 404, all of which are made of the same material. A reversing buckle 41, a third threaded buckle 42, a fourth threaded buckle 43, a first self-retracting telescopic belt 44, a second self-retracting telescopic belt 45, a first connecting buckle 46, a second connecting buckle 47, a third triangular hanging ring 48, and a fourth triangular hanging ring 49 are all installed on the fall arrestor belt 4.

[0078] like Figure 23 and Figure 24As shown, with the ground as the reference, climbing work is carried out on the power pole. The person climbs upward by stepping on foot buckle one and foot buckle two. Foot buckles are a common tool for climbing power poles. In order to intuitively see the combined use of the four straps of the safety belt, the main safety belt 2 and the backup safety belt rope 3 are attached to the first D-shaped loop 123 of the main waist belt 1 of the safety belt, and the fall protection belt 4 is temporarily attached to the magnetic second D-shaped loop 124 of the main waist belt 1 of the safety belt.

[0079] When first climbing a power pole, after putting on the smart safety harness, the worker climbs up by stepping on the foot buckles. At this time, the smart buckle on the main safety harness 2 is removed, and after circling the pole, it is attached to the magnetic second D-type hanging ring 124. When climbing below the first crossarm, only the main safety harness 2 is needed (the longer one is the first crossarm, and the shorter one is the second crossarm).

[0080] like Figure 25 As shown, without removing the main safety belt 2, the worker removes the smart buckle of the backup safety rope 3 from the top of the crossbeam and then hooks it onto the magnetic second D-type hanging ring 124. At this time, both the main safety belt 2 and the backup safety rope 3 are put into use. This is the first step in the buckling process.

[0081] Immediately afterwards, such as Figure 26 As shown, with the safety belt backup safety rope 3 still in place, the worker removes the smart buckle of the safety belt main safety belt 2 from below the crossbeam, then circles the crossbeam once from above, and finally attaches it to the magnetic second D-type hanging ring 124. At this point, both the safety belt main safety belt 2 and the safety belt backup safety rope 3 are in use. This is the second step in the buckling process.

[0082] Subsequently, as Figure 27 As shown, when the main safety harness 2 is not removed, the worker removes the smart buckle of the backup safety rope 3 from above the crossarm and re-attaches it to the first D-shaped hanging ring 123. At this time, only the main safety harness 2 is in use. This is the third and final step in the buckling process, and the buckling process is now complete.

[0083] Next, as Figure 28As shown, with the main safety harness 2 still in place, the worker removes the threaded buckle of the fall arrestor 4, wraps it around the pole once, and then attaches it to the first D-shaped hanging ring 123. At this point, both the main safety harness 2 and the fall arrestor 4 are in use. Because the fall arrestor 4 has been wrapped around the pole once via the reversing buckle, it adheres tightly to the pole under downward force, resulting in significant friction. For newcomers to the power industry, climbing power poles is an essential basic skill. However, due to a lack of technical experience, newcomers are prone to various unexpected dangers. Taking a training scenario for newcomers climbing power poles as an example, the poles they climb are usually single, straight poles with no obstructions, so there is generally no issue of the safety harness being accidentally fastened. However, precisely because of this, the potential risks should not be ignored. During pole climbing training, if the foot buckle comes loose or the body slips due to incorrect operation, the main safety belt of the traditional safety belt, which is not equipped with a fall arrestor, will not bear the force and cannot provide effective protection for the climber. If no corresponding fall arrestor measures are taken, it is very easy to cause personal injury accidents such as skin abrasions and fractures.

[0084] like Figure 29 The diagram shows a combination of safety harness attachments when workers are working under a crossbeam 2, with both the main safety harness 2 and the fall arrestor 4 in use. The safety harness backup rope 3 is attached to the magnetic second D-ring 124 around the perimeter of the pole, or the buckle of the backup rope 3 is attached to a sturdy frame of the crossbeam 2 for protection. In this case, the main safety harness 2, the backup rope 3, and the fall arrestor 4 are all in use, providing comprehensive protection for the worker. The backup rope 3 can be omitted if the fall arrestor 4 is in use and the attachment is deemed too cumbersome.

[0085] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
