Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-altitude operation safety protection equipment, in particular to an intelligent double-insurance tower climbing anti-falling protection device. BACKGROUND

[0002] At present, during the maintenance of overhead transmission lines with a voltage level of 500 kV or below, safety protection devices are generally needed for high-altitude workers to assist in climbing towers and protect their safety. The current safety protection devices include several types such as anti-falling double extension ropes, foot nail anti-falling devices, anti-falling safety rings, power-off installed anti-falling ladders / rails, unmanned aerial vehicle mounted tower climbing anti-falling devices, and unmanned aerial vehicle + small flying man devices. Based on the comprehensive consideration of factors such as cost, construction period, maintenance difficulty, safety performance, and compatibility, the anti-falling double extension ropes are generally used.

[0003] When climbing with the anti-falling double extension ropes, the high-altitude worker alternately uses two anti-falling extension ropes to hold the tower main material to climb up and down the tower. At least one anti-falling extension rope reliably holds the tower main material during the up-and-down tower process. However, when climbing with the anti-falling double extension ropes, the worker needs to frequently perform steps such as continuously untying, hanging the waist rope hook, and winding the waist rope out of the tower material, which is relatively cumbersome.

[0004] In summary, how to simplify the operation of climbing the tower is a problem that needs to be solved by the technical personnel in the field at present. SUMMARY

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] The core of this invention is to provide an intelligent double-insurance tower climbing fall protection device, which effectively simplifies the operation of climbing towers. Another core aspect of this invention is to provide a tower climbing operation method applicable to the aforementioned intelligent double-insurance tower climbing fall protection device.

[0064] Please refer to Figure 1The present invention provides an intelligent double-insurance tower climbing fall protection device, including a support component 1, two sets of protective components 2, two fall arrest belts 3, two sets of locking components 4, and mounting components 5. Both sets of protective components 2 include a rotating shaft 201, which is rotatably mounted on the support component 1. The first ends of the two fall arrest belts 3 are fixed to the corresponding rotating shafts 201, and the second ends of the two fall arrest belts 3 are provided with corresponding buckles 301. Both sets of locking components 4 include a switch 401, an actuating component 402, and a tensioning component. The actuating component 402 is rotatably mounted inside the support component 1, and the buckle 301 can be inserted into the support component 1. The actuating component 402 can be inserted into or removed from the buckle 301 to lock or unlock the buckle 301. The tensioning component has its first end connected to the actuating component 402 and its other end connected to the support component 1 to push the actuating component 402 to rotate forward and lock the buckle 301. The switch 401 is slidably mounted on the support component 1 to push the actuating component 402 to rotate backward and unlock the buckle 301. The mounting component 5 is used to fix the support component 1 to the fall arrest connecting seat.

[0065] like Figure 1 As shown, the support component 1 is used to install and support the locking component 4 and the protective component 2, etc. The support component 1 can be a housing or a base, etc.; and is equipped with two sets of protective components 2. In each set of protective components 2, the rotating shaft 201 is rotatably set in the support component 1. One end of the two fall arrest belts 3 is fixedly connected to the corresponding rotating shaft 201, so that the fall arrest belts 3 connected to them can be contracted or expanded by rotating the rotating shaft 201. At the other end of each fall arrest belt 3, a corresponding buckle 301 is provided by means of a locking pin, etc.

[0066] In conjunction with, such as Figure 1 , Figures 2 to 4 As shown, two sets of locking components 4 are provided on the support component 1, and the periphery of the support component 1 is reserved with a socket for the buckle 301 to be inserted into it. The actuating member 402 is rotatably disposed inside the socket of the support component 1, and the switching member 401 is slidably disposed at the socket of the support component 1. The end of the switching member 401 located inside the socket can abut against the left end of the actuating member 402 to drive the actuating member 402 to rotate counterclockwise. A tensioning member is provided between the actuating member 402 and the support component 1 to drive the actuating member 402 to always have a tendency to move toward the position of the locking buckle 301, that is, the tensioning member can drive the actuating member 402 to rotate clockwise.

[0067] It should be noted that there are no restrictions on the type of tensioning element, as long as it can achieve the above function. For example, a spring can be used, or two electromagnets can be included, and the electromagnets can be charged to control whether they apply a thrust to the actuator 402.

[0068] When it is necessary to lock the buckle 301, push the buckle 301 downward into the interior of the support component 1, forcing the actuating element 402 to deflect counterclockwise. After the buckle 301 is inserted to a certain depth, the actuating element 402 will deflect clockwise under the push of the tensioning element, so that the upper end of the actuating element 402 extends into the through hole in the middle position of the buckle 301, thereby locking the buckle 301. Conversely, when it is necessary to unlock the buckle 301, push the switch element 401 downward to drive the left end of the actuating element 402 to deflect counterclockwise, so that the upper end of the actuating element 402 can be withdrawn from the buckle 301.

[0069] Furthermore, the support component 1 is provided with an installation part 5, such as a strap and a buckle structure, so that the fall protection device can be fixedly connected to the fall protection connection seat of the high-altitude work personnel's wear equipment.

[0070] In use, pull the fall arrest belt 3 in a set of protective components 2 to unfold it, and insert the buckle 301 set therein into a socket in a set of support components 1 so that a set of locking components 4 locks the buckle 301. Then, you can press the switch 401 in another set of locking components 4 to unlock the buckle 301 set in the fall arrest belt 3 of another set of protective components 2. With this setting, on the one hand, the fall protection device can effectively protect workers at heights, and on the other hand, the fall protection device has a simple structure, is easy to use, and effectively simplifies the operation of climbing poles and towers.

[0071] Based on the above embodiments, the protective component 2 also includes a retractor 202, one end of which is fixed to the support component 1 and the other end is fixed to the rotating shaft 201. The retractor 202 can rotate around the rotation center line of the rotating shaft 201 to tighten or loosen the rotating shaft 201.

[0072] like Figure 4 As shown, the retractor 202 adopts a coil spring structure, and one end of the retractor 202 is fixedly connected to the rotating shaft 201 by welding or bolt connection, while the other end is installed on the support assembly 1 by a clamp or plug rod, so that the retractor 202 can tighten or loosen with the rotation of the rotating shaft 201.

[0073] In use, pull the free end of the fall arrestor 3 to unfold it. At the same time, the retractor 202 tightens as the shaft 201 rotates. After pressing the corresponding switch 401, the corresponding buckle 301 can be unlocked. Under the tension of the retractor 202, the shaft 201 can be rotated to automatically roll up the fall arrestor 3. This design helps to further simplify the operation of climbing the tower and reduce the difficulty of climbing.

[0074] Based on the above embodiments, both sets of protective components 2 further include a rotating wheel 203, a pawl 204, a ratchet 205, and a reset member 206; the ratchet 205 is fixed to the support component 1, and the inner wall of the ratchet 205 has ratchet teeth; the rotating wheel 203 is coaxially fixed to the corresponding rotating shaft 201, and two ratchet wheels 205 are coaxially sleeved inside the corresponding ratchet wheel 205; a plurality of pawls 204 are rotatably disposed on the outer periphery of the corresponding rotating wheel 203, and the rotating shaft 201 of the plurality of pawls 204 is parallel to the rotating shaft 201 of the corresponding rotating wheel 203; the plurality of pawls 204 are connected to the corresponding rotating wheel 203 through the reset member 206, and the reset member 206 is used to drive the free end of the pawl 204 to approach the rotating wheel 203, so as to drive the pawl 204 to reset.

[0075] like Figure 5 As shown, the ratchet 205 is a hollow structure with ratchet teeth machined on its inner wall. The rotating wheel 203 is fitted inside the corresponding ratchet 205 and is coaxially and fixedly connected to the corresponding rotating shaft 201. The tail end of the pawl 204 is rotatably disposed on the circumference of the corresponding ratchet 205, and the rotation center line of the pawl 204 is parallel to the rotation center line of the corresponding rotating wheel 203. During the rotation of the rotating wheel 203, under the action of centrifugal force, the free ends of the pawls 204 connected to the rotating wheel 203 can open and deflect towards the side away from the rotation center line of the rotating wheel 203, so that the free ends of the pawls 204 engage with the corresponding ratchet teeth. Furthermore, a reset member 206 is provided between the pawl 204 and the corresponding rotating wheel 203 to apply a pulling force to the pawl 204, thereby driving the opened pawl 204 to reset.

[0076] When in use, if a worker falls at high speed from a height, the fall arrest belt 3 is pulled out at high speed, so that the rotating component and the pawl 204 connected to the rotating component are driven to rotate at high speed through the rotating shaft 201. Under the action of centrifugal force, the pawl 204 engages with the corresponding ratchet tooth to prevent the fall arrest belt 3 from being continuously pulled out, thereby preventing the worker from falling from the tower.

[0077] It should be noted that the type of reset component 206 is not limited, as long as it can achieve the above function. For example, a spring can be used, or the same or opposite magnetic poles can be used.

[0078] Based on the above embodiments, the two sets of locking components 4 are connected by a linkage component, which is used to lock or unlock the corresponding action element 402 to further improve the safety of high-altitude workers using the fall arrest device.

[0079] It should be noted that the type of linkage component is not limited, as long as it can achieve the above functions. For example, in some specific embodiments, the linkage component includes a connecting rod and a rotating seat. The rotating seat is mounted on the support component 1, and the middle segment of the connecting rod is rotatably connected to the rotating seat. (Refer to...) Figure 2As shown, one end of the linkage is connected to the lower end of the switch element 401 in one set of latching assemblies 4, and the other end is connected to the lower end of the switch element 401 in another set of latching assemblies 4. This allows the switch element 401 in the other set of latching assemblies 4 to spring upwards when pressed downwards, thus unlocking the corresponding latch 301 when the switch element 401 in the other set of latching assemblies 4 is pressed downwards. Alternatively, in some other embodiments, the linkage assembly includes two drive elements and a sub-controller, with the sub-controller signal-connected to the two drive elements. The output end of one drive unit is connected to the switch 401 in a set of latching assemblies 4, and the output end of another drive unit is connected to the switch 401 in another set of latching assemblies 4, so as to drive the switch 401 to move. The output end of one drive unit is controlled by a sub-controller to move forward to press the switch 401 connected to it, so that the switch 401 in this set of latching assemblies 4 unlocks the corresponding buckle 301. The output end of the other drive unit is controlled to move in the opposite direction to pull the switch 401 connected to it to pop up, so that the switch 401 in this set of latching assemblies 4 pops up.

[0080] Based on the above embodiments, the support component 1 is further provided with a power supply 6, a controller 7 and an encoder switch 8; the controller 7 is signal-connected to the linkage component, and the encoder switch 8 is electrically connected to the power supply 6 and the controller 7 to control the on / off state of the controller 7, so as to control the working mode of the intelligent double-insurance tower fall protection device.

[0081] like Figure 6 As shown, a power supply 6, a controller 7, and an encoder switch 8 are installed on the support component 1. The power supply 6 supplies power to the controller 7, and the encoder switch 8 is set on the power supply circuit of the controller 7 to control the on and off of the controller 7, thereby allowing the fall protection device to switch back and forth between automatic and manual modes. In automatic mode, the controller 7 controls the linkage component to automatically control whether the two sets of locking components 4 are switched to the unlocked state. In manual mode, the controller 7 stops controlling and the two sets of locking components 4 are manually switched to the unlocked state by pressing the switch 401.

[0082] This setup not only meets the needs of different scenarios such as testing and climbing, but also simplifies the operation of climbing poles.

[0083] Based on the above embodiment, the support component 1 is further provided with an early warning device 9 and two detectors 10; the early warning device 9 and the two detectors 10 are all electrically connected to the power supply 6; the two detectors 10 are used to detect the position of the switch 401 in the corresponding latch component 4, and the two detectors 10 are signal connected to the early warning device 9 so as to provide a status reminder when both latch components 4 are in the unlocked state.

[0084] like Figure 6As shown, two detectors 10 and an early warning device 9 are installed on the support assembly 1. The power supply 6 is electrically connected to the two detectors 10 and the early warning device 9 to supply power to them. The two detectors 10 are used to detect the working status of the corresponding locking assembly 4. The early warning device 9 is signal connected to the two detectors 10 to receive the detection results of the two detectors 10. When the two detectors 10 detect that both sets of locking assemblies 4 are in the unlocked state, an alarm signal is issued to remind the high-altitude workers to check the position of the buckles 301 set on the two fall arrest belts 3.

[0085] It should be noted that the type of warning device 9 is not limited, as long as it can achieve the above functions. For example, the warning device 9 can use a buzzer or other sound signal indicator to provide an audible warning, and / or the warning device 9 can also use an indicator light or other light signal indicator to provide an audible warning.

[0086] It should also be noted that the types of the two detectors 10 are not limited, as long as they can achieve the above functions. For example, Figure 8 As shown, in some specific embodiments, both detectors 10 are switches, the power supply 6, the alarm and the two detectors 10 are connected in series, and when the switch 401 in the two sets of latching assemblies 4 moves away from the actuating member 402, it can push the corresponding detector 10 to close. When both sets of latching assemblies 4 are in the unlocked state, both detectors 10 will close to supply power to the warning device 9, so that the warning device 9 can provide a status reminder to remind the high-altitude workers. Alternatively, in other specific embodiments, both detectors 10 are position sensors. The two detectors 10 are used to detect the position of the corresponding switch 401, and both detectors 10 are signal connected to the warning device 9 so that when both sets of latching assemblies 4 are in the unlocked state, the detection result of the position sensor can be used to control the warning device 9 to provide a status reminder.

[0087] Based on the above embodiments, the support component 1 is further provided with a communicator 11, a speaker and a microphone 12; the power supply 6 is electrically connected to the communicator 11, the speaker and the microphone 12, the controller 7, the microphone 12 and the speaker are all signal connected to the communicator 11, and the communicator 11 is used for wireless signal connection to external communication devices.

[0088] like Figure 1 , Figure 6 and Figure 7As shown, the communicator 11 has a wireless signal transmission structure such as an antenna, enabling it to wirelessly connect with external communication devices such as walkie-talkies. The communicator 11 is also electrically connected to a microphone 12, allowing it to receive the voice emitted by the high-altitude workers through the microphone 12 and transmit it to the external communication devices through the communicator 11. Ground staff can then use the external communication devices to communicate simply with the high-altitude workers. The support assembly 1 also has a speaker, which is also connected to the communicator 11. In use, the communicator 11 receives the signal from the external communication devices and transmits it to the speaker for broadcast, enabling ground staff and high-altitude workers to communicate interactively.

[0089] Furthermore, the controller 7 is signal-connected to the communicator 11 so that the status of the controller 7 can be transmitted to external devices through the communicator 11. This allows ground personnel to know whether the current mode is automatic or manual. In some embodiments, during use, in automatic mode, when the latch 301 in one set of locking components 4 is locked, but the latch 301 in another set of locking components 4 does not automatically pop out, the high-altitude worker can use the microphone 12 and speaker to communicate with the ground personnel to adjust to manual mode with the consent of the ground personnel. At the same time, the external device outputs status reminders, such as "automatic mode", "manual mode", or "automatic status", "manual status", etc.

[0090] Furthermore, the support component 1 is also equipped with a PTT button 14, which is electrically connected to the microphone 12 and the controller 7. When in use, pressing the PTT button 14 will switch the microphone 12 to the communication mode, and conversely, releasing the PTT button will switch the microphone 12 to the non-communication mode, so as to facilitate communication when needed and to remain silent when not needed, thus meeting the communication needs. Furthermore, the support component 1 is also equipped with a volume switch 13 to control the speaker volume, so as to adjust the volume of the speaker output sound.

[0091] Based on the above embodiments, a monitoring wristband for monitoring the physiological parameters of high-altitude workers is also included. The wristband signal is connected to the communicator 11 to transmit the physiological parameters of high-altitude workers to ground staff in real time, so that ground staff can predict and intervene in a timely manner based on real-time monitoring data, such as blood pressure and heart rate, thereby improving the efficiency of responding to emergencies.

[0092] Based on the above embodiments, the support component 1 is a hollow shell, the protective component 2 is disposed inside the support component 1, and the peripheral wall of the support component 1 has two movable through holes for the corresponding fall arrestor belt 3 to extend to the outside of the support component 1.

[0093] like Figure 6As shown, the support component 1 adopts a hollow shell structure in the shape of a cuboid or cylinder to accommodate the protective component 2 inside. Correspondingly, rectangular or long strip-shaped movable through holes are opened on the peripheral wall of the support component 1, so that the fall protection belt 3, which is connected to the rotating shaft 201 at one end, passes through the corresponding movable through hole and extends to the outside of the support component 1 to connect to the buckle 301. This simplifies the structure of the fall protection device and helps to ensure the smooth operation of the fall protection device.

[0094] Based on the above embodiments, the middle section of the fall arrest belt 3 is provided with a positioning member 302, which can abut against the outer surface of the support component 1 to position the length of the fall arrest belt 3 located on the outer section of the support component 1.

[0095] like Figure 1 , Figure 6 and Figure 7 As shown, the positioning element 302 can be a structure such as a rivet or a pin, and the positioning element 302 is inserted on the section of the fall arrest belt 3 located outside the support assembly 1. In order to limit the length of the section of the fall arrest belt 3 located outside the support assembly 1 by abutting against the outer wall of the support assembly 1 during the process of the fall arrest belt 3 shrinking and winding to the outer circumference of the rotating shaft 201, so as to meet the operational needs.

[0096] Furthermore, the fall arrestor belt 3 has several scale lines evenly arranged along its own length to facilitate the determination of the position of the positioning member 302, so as to ensure the length of the belt segment reserved on the outer side of the support assembly 1 during use.

[0097] Based on the above embodiments, the support component 1 includes a rectangular shell 101 and a baffle 102; the inner cavity of the rectangular shell 101 is divided by the baffle 102 into a first accommodating cavity 103, a second accommodating cavity 104, a third accommodating cavity 105 and a fourth accommodating cavity 106 arranged sequentially along the length direction of the rectangular shell 101, and the two first accommodating cavities 103, the two second accommodating cavities 104, the two third accommodating cavities 105 and the two fourth accommodating cavities 106 are all arranged along the width direction of the rectangular shell 101; two sets of protective components 2 are disposed in the corresponding first accommodating cavity 103, two sets of locking components 4 are disposed in the corresponding fourth accommodating cavity 106, the controller 7 and the warning device 9 are disposed in the corresponding second accommodating cavity 104, and the communicator 11 and the power supply 6 are disposed in the corresponding third accommodating cavity 105.

[0098] like Figure 6 and Figure 7As shown, in the support assembly 1, a rectangular shell 101 is located on the outer periphery, and a baffle 102 is located on the inner side. The baffle 102 is set in the inner cavity of the rectangular shell 101 by means of integral molding or screw connection, so as to divide the inner cavity of the rectangular shell 101 into eight accommodating cavities arranged in a matrix, namely, the first accommodating cavity 103, the second accommodating cavity 104, the third accommodating cavity 105 and the fourth accommodating cavity 106 arranged from left to right. The two first accommodating cavities 103 are arranged along the width direction of the rectangular shell 101, the two second accommodating cavities 104 are arranged along the width direction of the rectangular shell 101, the two third accommodating cavities 105 are arranged along the width direction of the rectangular shell 101, and the two fourth accommodating cavities 106 are arranged along the width direction of the rectangular shell 101.

[0099] Correspondingly, two first accommodating cavities 103 arranged side-by-side on the left end of the support assembly 1 are respectively provided with corresponding protective assemblies 2, and two movable through holes connected to the corresponding first accommodating cavities 103 are opened on the left wall of the rectangular housing 101 so that the left ends of the fall arrest belts 3 in the two sets of protective assemblies 2 can extend to the outside of the support assembly 1; two fourth accommodating cavities 106 arranged side-by-side on the right end of the support assembly 1 are respectively provided with corresponding locking assemblies 4 and detectors 10, and two insertion ports connected to the corresponding fourth accommodating cavities 106 are opened on the right wall of the rectangular housing 101 so that the buckles 301 can be inserted; a warning device 9 and a controller 7 are respectively provided in the two second accommodating cavities 104 arranged side-by-side, and a power supply 6 and a communicator 11 are respectively provided in the two third accommodating cavities 105 arranged side-by-side. With this arrangement, the fall arrest protection device has a simple structure, reasonable layout, is conducive to miniaturization design, and is easy to wire.

[0100] It should be noted that there are no restrictions on the type and number of baffles 102, as long as they meet the requirements of separating the inner cavity of the support assembly 1. For example, in some specific embodiments, the baffles 102 adopt a flat plate structure, and the baffles 102 include a first baffle 102 and a second baffle 102. The first baffle 102 extends along the width direction of the rectangular shell 101, and the second baffle 102 extends along the length direction of the rectangular shell 101, and the second baffle 102 is inserted into the middle position of the first baffle 102; or, in other specific embodiments, the baffles 102 are an integral structure, such as a grid-shaped structure.

[0101] Based on the above embodiments, the support component 1 further includes a first mounting base 107, which is mounted on the rectangular housing 101. The rotating shaft 201 is mounted on the first mounting base 107. The first mounting base 107 may be a U-shaped plate or a Y-shaped plate, etc.

[0102] Based on the above embodiments, the support assembly 1 further includes a second mounting base 108, which is a housing structure. The side wall of the second mounting base 108 has a second movable through hole. One end of the switch member 401 is slidably inserted into the interior of the second mounting base 108, and the other end is slidably passed through the second movable through hole and extends to the outside of the second mounting base 108. The actuating member 402 is rotatably disposed inside the second mounting base 108, and the head end of the buckle 301 can be inserted into or pulled out of the second mounting base 108 through the second movable through hole.

[0103] In addition to the aforementioned intelligent double-insurance tower climbing fall protection device, the present invention also provides a control method applicable to the intelligent double-insurance tower climbing fall protection device disclosed in the above embodiments, the control method comprising the following steps:

[0104] Step S11: Obtain the working mode of the intelligent dual-insurance tower fall protection device; it can be understood that the working mode of the fall protection device is detected and obtained in order to prepare for the next step.

[0105] Step S12: If the intelligent double-insurance tower fall protection device is in automatic mode, obtain the position of the switch 401 in the two sets of locking assemblies 4; it can be understood that when it is determined that the fall protection device is in automatic mode, the position of the switch 401 in the two sets of locking assemblies 4 is detected in real time, so that the working position of the action 402 in the two sets of locking assemblies 4 can be controlled by the detection result in the next step.

[0106] Step S23: When the switch 401 in the first locking assembly 4 slides to the unlock position, it is determined whether the switch 401 in the second locking assembly 4 is in the locked position. If yes, the actuator 402 in the first locking assembly 4 is unlocked; otherwise, the actuator 402 in the first locking assembly 4 remains locked. It can be understood that when the switch 401 in the first locking assembly 4 is detected to be pressed and slide towards the actuator 402, the position of the switch 401 in the second locking assembly 4 is detected to determine whether it is in the locked position. That is, it is determined whether the switch 401 in the second set of locking components 4 has slid to a state that allows the corresponding action 402 to lock the corresponding buckle 301. If the switch 401 in the second set of locking components 4 is indeed in the locked position, then the second set of locking components 4 is locking the buckle 301 that it is plugged into, thereby controlling the unlocking of the action 402 in the first set of locking components 4, so that when the switch 401 in the first set of locking components 4 is pressed, the action 402 in the first set of locking components 4 can be pushed to unlock the buckle 301 that it is plugged into.

[0107] To ensure the safety of workers at height, based on the above embodiment, the method further includes acquiring a work cycle T0, where T0 is a time interval, and acquiring the time difference T1 between the self-locking state and the unlocking state of the switch 401 in the first or second set of locking components 4. The time difference T1 is then compared with the work cycle T0. When the time difference T1 is not within the work cycle T0, a status information prompt for the worker at height is transmitted to an external communication device. It is understood that the work cycle T0 can be set according to different workers at height, and the first set of locking components can be detected in real time during the worker's climb of the tower. The time difference T1 between the sliding of the switch 401 in component 4 from the locked position to the unlocked position is the time taken for the corresponding buckle 301 to be inserted into the first set of locking components 4 and then pulled out. Similarly, the time difference T1 between the sliding of the switch 401 in the second set of locking components 4 from the locked position to the unlocked position can also be detected in real time. It should be noted that the method of obtaining the time difference T1 is not limited. For example, the working position of the switch 401 in the locking components 4 after sliding can be recorded one by one, and the position change time can be recorded, and then it can be calculated to obtain the time difference T1.

[0108] Furthermore, when a worker is climbing at height in a normal state, if the time difference T1 obtained through real-time detection is within the work cycle T0 (i.e., T1 is greater than or equal to the minimum limit of the work cycle T0, and less than or equal to the maximum limit of the work cycle T0), then there is no need to transmit a signal to the external communication device for a reminder. However, if a worker is cheating, and the time difference T1 obtained through real-time detection falls outside the work cycle T0 (i.e., T1 is greater than the maximum limit of the work cycle T0, or less than the minimum limit of the work cycle T0), then it is necessary to transmit a signal to the external communication device for a status reminder. For example, if a worker is slacking off and their average climbing speed is slow, a signal to control their vibration can be sent to the external communication device. Or, if a worker is resting, a text message can be sent to the external communication device to inform ground staff that the worker is currently resting. Of course, this is not limited to the examples mentioned above. This setup can promptly inform ground staff of the worker's status, allowing them to pay attention to the status of the worker on the tower.

[0109] Similarly, to ensure the personal safety of workers at height, based on the above embodiment, the method also includes obtaining the position change cycle S0, which is the displacement range of the worker climbing the tower. During the position change cycle S0, the method checks whether the switch 401 in the first and / or second group of locking components 4 changes state. If not, it transmits an abnormal status information prompt to the external communication device. It can be understood that the position change cycle S0 can be set according to different workers at height, and during the worker's climbing of the tower, the method detects in real time in each position change cycle S0 whether the first and / or second group of switch 401 changes its working position, i.e. whether the buckle 301 has been inserted into the corresponding group of locking components 4 and the switch 401 has been pushed to unlock the buckle 301. If not, the worker at height is likely to have engaged in non-standard work behavior, and a vibration signal or text signal is transmitted to the external communication device to remind the ground workers to pay attention to the status of the worker at height on the tower.

[0110] In addition to the aforementioned intelligent double-insurance tower climbing fall protection device and control method, the present invention also provides a tower climbing operation method applicable to the intelligent double-insurance tower climbing fall protection device disclosed in the above embodiments, the tower climbing operation method comprising the following steps:

[0111] Step S21: Wrap the first fall protection belt 3 over the main material above the tower node at chest height of the worker, then insert the buckle 301 connected to the first fall protection belt 3 into the support assembly 1, and lock the buckle 301 connected to the first fall protection belt 3 through the first locking assembly, and then switch the fall protection device to automatic mode; it can be understood that before climbing begins, the first fall protection belt 3 is hung on the main material near the bottom node of the tower, and the buckle 301 connected to the first fall protection belt 3 is locked to provide safety protection through the first fall protection belt 3, and then the fall protection device is adjusted to automatic mode to prepare for subsequent climbing operations.

[0112] Step S22: After climbing upwards until another tower node is encountered, attach the first fall arrestor 3 to the foot spikes around the main structure of the current tower node, and then loop the second fall arrestor 3 over the main structure above the node at chest height of the worker's current position. Then, insert the buckle 301 connected to the second fall arrestor 3 into the support assembly 1 to lock the buckle 301 connected to the second fall arrestor 3 through the second locking assembly. It can be understood that after climbing upwards to another tower node, the second fall arrestor 3 is replaced for safety protection.

[0113] Step S23: Press the switch 401 of the first set of locking components 4 so that the buckle 301 connected to the first fall arrest belt 3 pops out of the support component 1, and then continue to climb upwards; it is understood that after ensuring the safety protection performance of the second fall arrest belt 3, the first fall arrest belt 3 is unlocked so as to continue to climb upwards.

[0114] Step S24: After climbing upwards until another tower node is encountered, attach the second fall protection strap 3 to the foot spikes around the main structure of the current tower node, and then loop the first fall protection strap 3 over the main structure above the chest height node of the worker's current position. Then, insert the buckle 301 connected to the first fall protection strap 3 into the support assembly 1 to lock the buckle 301 connected to the first fall protection strap 3 through the first locking assembly. It is understood that after climbing to another tower node, the first fall protection strap 3 will be replaced for safety protection.

[0115] Step S25: Press the switch 401 of the second set of locking components 4 so that the buckle 301 connected to the second fall arrest belt 3 pops out of the support component 1, and then continue to climb upwards; it is understood that after ensuring the safety protection performance of the first fall arrest belt 3, the second fall arrest belt 3 is unlocked so as to continue climbing upwards.

[0116] Step S26: Repeat steps S22, S23, S24 and S25 in sequence until you reach the target position.
