Abstract
Description
Technical Field
[0001] The present invention relates to the field of power system safety equipment, and in particular to an artificial climbing and anti-falling protection device. Background Art
[0002] Transmission line towers require regular maintenance, requiring workers to climb the towers for high-altitude work. These workers are required to wear fall arrest gear. Suspended fall arrest gear is typically temporarily installed by the first worker climbing the tower and then removed by the last worker descending after work is complete. This means neither the first climber nor the last climber is protected by a fall arrest device during their ascent, making it impossible to guarantee the safety of any individual worker and increasing the overall risk of tower climbing.
[0003] Later, the anti-fall device was used in conjunction with the drone. The anti-fall device generally consists of two parts: a hook mechanism and a hook mechanism. The hook mechanism and the hook mechanism are detachably connected. After the hook mechanism and the hook mechanism are connected, the drone will hang the hook mechanism on the cross arm of the tower or the support rod on the tower.
[0004] There is still some room for improvement in the existing anti-fall device. On the one hand, the hook mechanism has a certain impact on the drone during the lifting, landing, hanging and disassembly process.

The boom portion 113 includes boom 1 b1, the upper end of which is hinged to the lower end of the flange rod a3 via a cross connector b2, that is, connected to the cross connector via a pin. The pin can be a common general-purpose pin commonly found on the market. The lower end of boom 1 b1 is hinged to boom 2 b3, the lower end of boom 2 b3 is hinged to boom 3 b4, and the lower end of boom 3 b4 is hinged to a boom connector b5. The number of booms can also be increased or decreased according to actual conditions. The cross connector b2 and boom 1 b1, boom 1 b1 and boom 2 b3, boom 2 b3 and boom 3 b4, and boom 3 b4 and boom connector b5 are all hinged and can rotate freely. Among them, boom 1 b1, boom 2 b3, and boom 3 b4 are all hinged and rotated on the same horizontal plane.
[0052] The lower end of the boom assembly 11 is connected to the sling assembly 12. The sling assembly 12 comprises two hooks 121 arranged in a figure-eight configuration. The upper ends of the two hooks 121 gradually approach and extend upward to form a single unit. Each hook 121 comprises a hook front plate c1 and a hook rear plate c2, spaced apart from each other. One hook houses a control box 125, while the other houses a battery box 126. The control box 125 and battery box 126 are secured via bolts secured to corresponding holes in the hook rear plate c2 and hook front plate c1.
[0053] A hook fixing block 122 is located above the connection between the two hooks 121. Specifically, the hook front plate c1 and hook rear plate c2 of the two hooks 121 extend upward from the middle connection. The hook fixing block 122 is located at the middle connection. Multiple hook fixing bolts c3 are provided on the two hooks 121, securing the hook fixing block 122, hook rear plate c2, and hook front plate c1. A boom fixing bolt c4 is located above the hook fixing block 122. The boom fixing bolt c4 passes through the hook front plate c1 and hook rear plate c2 at the middle connection. A boom connector b5 is connected to the boom fixing bolt c4.
[0054] A square slot e1 is provided at the bottom of the hook fixing block 122. A pin 123 is slidably provided within the hook fixing block 122, which can move left and right. The pin 123 is driven by a transmission mechanism 124 to be pulled out of or pushed into the hook fixing block 122 and the square hole 241. The transmission mechanism 124 includes a rotatable rotating block d1, one side of which is fixedly connected to a flange d4. The flange d4 is driven to rotate by the motor shaft d5. The motor is mounted within the motor fixing block d6, which is fixedly mounted on the hook rear plate c2. The motor is electrically connected to the control box 125. The upper portion of the rotating block d1 is fixedly connected to a rear arm d2. The end of the rear arm d2 away from the rotating block is hingedly connected to a front arm d3. The end of the front arm d3 away from the rear arm d2 is hingedly connected to a pin 123. Pin 123 passes through a hole in the hook fixing block 122. The hole diameter is slightly larger than the diameter of pin 123. The specifications of the square hole 241 are much larger than those of pin 123. Pin 123 can slide in the hole in the hook fixing block 122 and the square hole 241. The lower portion of the rotating block d1 is fixedly connected to a limit plate d7. A limit sensor d8 for detecting the limit plate d7 is also provided in the hook. Limit sensor d7 is electrically connected to the control box 125.
[0055] When the motor shaft d5 rotates, the flange d4 rotates, which in turn rotates the rotating block d1. The rotation of the rotating block d1 then rotates the rear arm d2 and the limit plate d7. Since the front arm d3 and the rear arm d2 are hinged, the rotation of the rear arm d2 drives the front arm d3 to swing. Simultaneously, since the front arm d3 is also hinged to the pin 123, the swing of the front arm d3 drives the pin 123 to move. Since the pin 123 passes through the hole of the hook fixing block 122, the swing of the front arm d3 can pull the pin 122 out of or push it into the hole of the hook fixing block 122 and the square hole 241, thereby achieving a detachable connection between the hook mechanism 1 and the hook mechanism 2.
[0056] An upper camera 127 is installed on the hook fixing block 122 to observe the extension and retraction of the pin.

[0067] The second is the middle state of the snap-fit claw, refer to Figure 13 When the lifting rod 232 is pulled upward by an external force, when the pulling force is greater than the suction force of the magnet 235, the lifting rod 232 will move upward and drive the lifting rod pin 233 and the iron block 234 passing through the pin to move upward, but at this time due to the action of gravity, the locking claw 22 still remains in a closed state.
[0068] The third is the state where the snap-on claw is open. Figure 14 Based on the second state, when the lifting rod 232 is further pulled upward by an external force, the lifting rod pin 233 will press against the top of the slide groove 1 221, lifting the locking claw 22. The locking claw 22 rotates around the locking claw pin 222, and the locking claw 22 enters the open state, opening the front hook 211 and the rear hook 212. The above describes the process of the locking claw from the closed and locked state to the fully open state. Similarly, the process from opening to the closed and locked state is the reverse process of the above process.
[0069] Reference Figure 18-19 , which illustrates the docking and separation of hook mechanism 1 and hook mechanism 2. The rotation of motor shaft d5 drives the rotation of flange d4 mounted on motor shaft d5, which in turn drives the rotation of rear arm d2 mounted on flange d4. Rear arm d2 is hinged to front arm d3 via a pin, and front arm d3 is hinged to pin 123 via a pin. When motor shaft d5 rotates counterclockwise, pin 123 passes through square hole 241 at the lower end of guide rail 24 and inserts into the left opening of hook fixing block 122, successfully docking hook mechanism 2 with hook mechanism 1.
[0070] When docking is successful, limit sensor d8 detects one edge of limit plate d7. Control box 125 receives a signal from limit sensor d8 and stops the motor to prevent it from stalling and burning out. When motor shaft d5 rotates clockwise, pin 122 retracts into the hole on the right side of hook fixing block 122, successfully separating hook mechanism 2 and hook mechanism 1. When separation is complete, limit sensor d8 detects the other edge of limit plate d7. The control panel of control box 125 receives a signal from limit sensor d8 and stops the motor to prevent pin 123 from being dislodged from the hole in hook fixing block 122.
[0071] The operating process of the present invention is as follows: before the climber ascends, the docked hook mechanism 1 and hook mechanism 2 are installed under the drone, and the drone is controlled to suspend the climbing anti-fall protection device and install it on the cross arm at the top of the transmission line tower. The hook mechanism 1 and hook mechanism 2 are controlled to separate, and the drone returns to the ground with the hook mechanism 1, and the hook mechanism 2 is hung on the tower cross arm 3. On the ground, the climber installs the anti-fall self-locking device 253 on the protection rope 252, connects his or her own safety belt to the ring of the anti-fall self-locking device 253, and begins to climb. Even if the climber accidentally falls during the climbing process, the anti-fall self-locking device 253 will automatically lock the protection rope 252 to prevent the climber from falling to the ground, thereby protecting the climber. After the climber completes the operation, the hook mechanism 1 is docked with the hook mechanism 2 by the drone, and the hook mechanism 2 is brought back to the ground.
[0072] The specific implementation is as follows:
[0073] Before workers start working at height, they should first install the anti-fall protection device. The boom fixing base 111 is fixed to the lower center of the drone with bolts or clips. The boom connector b5 is passed through the boom fixing bolt c4. The control panel inside the control box 125 controls the motor to rotate clockwise. The motor shaft d5 drives the rear support arm d2 and the front support arm d3 to rotate, and the pin 123 is pulled out from the circular hole of the hook fixing block 122 (see Figure 19 ), at this time, the limit sensor d8 detects the edge of the limit plate d7 and transmits the signal to the control board in the control box 125, which controls the motor to stop rotating to prevent the pin shaft 123 from falling out of the hole of the hook fixing block 122. After the hook mechanism 1 and the hook mechanism 2 are docked, the control board in the control box 125 controls the motor to rotate counterclockwise, and the motor shaft d5 drives the rear support arm d2 and the front support arm d3 to rotate, so that the pin shaft 123 is inserted into the circular hole of the hook fixing block 122. Figure 18 The hook mechanism 1 and hook mechanism 2 are locked. At this time, the limit sensor d8 detects the edge of the limit plate d7 and transmits a signal to the control board, which stops the motor to prevent it from stalling and burning. The docking of the hook mechanism 1 and hook mechanism 2 is complete.
[0074] Start the drone to take off. As the drone gradually flies off the ground, the boom 1 b1, boom 2 b3, and boom 3 b4 gradually straighten due to the hinged connection. When the hook mechanism 2 leaves the ground, the flange rod a3 moves down due to the heavy weight of the hook mechanism 2 and the protection rope 252, and the spring a2 in the buffer chamber a1 is compressed. Figure 14 As the pin shaft 123 drives the guide rail 241 of the hook mechanism 2 to move upward, and then drives the lifting rod 232 to move upward, the pulling force is greater than the attraction between the iron block 234 and the magnet 235, and the iron block 234 and the magnet 235 are separated. When the lifting rod 232 continues to be pulled upward by the external force, the lifting rod pin 233 will press against the top of the slide groove 221, and lift the engaging claw 22. The engaging claw 22 rotates around the engaging claw pin 222, and the engaging claw 22 is in an open state. The openings of the front hook 211 and the rear hook 212 are opened. At this time, the lifting rod 232 is in a fully extended state.
[0075] The drone arrives at the tower crossarm 3. Using camera 1 128, located below the control box 125, and camera 2 129, located below the battery box 126, the drone adjusts its position to ensure it is directly below the hook mechanism 2. The drone then slowly descends until the hook mechanism engages the tower crossarm 3. As the drone continues to descend, the spring a2 within the buffer chamber a1 begins to expand, and the flange a3 begins to move upward. As the drone continues to descend, the lifting rod 232 begins to descend. As the lifting rod pin 233 moves downward, the engaging claw 22 begins to close. When the lifting rod pin 233 slides to the bottom of the chute 1 221, the engaging claw 22 closes and locks. Simultaneously, the iron block 234 connected to the lifting rod pin 233 contacts the magnet 235 and engages. The drone then continues to descend for a distance and hovers. At this time, since the first boom b1, the second boom b3, and the third boom b4 are all hingedly connected, they automatically adapt to the folding posture according to the hovering position of the drone.
[0076] The ground operator uses a wireless remote control to operate the control panel inside the control box 125 to control the motor to rotate clockwise. The motor shaft d5 drives the rear support arm d2 and the front support arm d3 to rotate, and the pin shaft 123 is pulled out from the circular hole of the hook fixing block 122. The upper camera 127 is used to observe that the pin shaft 123 has been pulled out.
[0077] The drone is then maneuvered upward, lifting off with hook mechanism 1 and landing on the ground. Hook mechanism 2 remains attached to the tower crossarm 3. The climber then uses the hooked safety rope 252 to install the anti-fall self-locking device 253, connects the safety belt to the anti-fall self-locking device 253, and then proceeds with the ascent.
[0078] After the worker completes the elevated work and returns to the ground, they need to remove hook mechanism 2. The drone then launches, driving hook mechanism 1. After reaching directly above hook mechanism 2, the drone uses camera 1 127, located below control box 125, and camera 2 129, located below battery box 126, to observe the hook position and adjust the drone's orientation. The upper camera 127 observes the position of guide rail 24 below, aligning the two and gradually lowering the drone. When hook 121 and guide rail 24 make contact, the hook 121 forms an "eight" shape, while the guide rail 24 forms an inverted "eight" shape. Even if there is a slight deviation, the docking can still be corrected. The ground operator uses a wireless remote control to operate the control panel inside control box 125, controlling the motor to rotate counterclockwise. The motor shaft d5 rotates the rear arm d2 and the front arm d3, inserting the pin 123 inward through the circular hole in the hook fixing block 122, locking hook mechanism 1 and hook mechanism 2. The upper camera 127 confirms that the pin 123 is in place.
[0079] During the movement of the pin 123, the drone always hovers above the hook and keeps the boom 1 b1, boom 2 b3, and boom 3 b4 in a folded state. At this time, even if the wind causes the drone to drift, since the boom 1 b1, boom 2 b3, and boom 3 b4 are hingedly connected and in a folded state, it will not affect the docking stability of the hook mechanism 1 and the hook mechanism 2.
[0080] After the docking is completed, the drone is pulled up. At this time, the boom 1 b1, boom 2 b3, and boom 3 b4 gradually straighten. When the drone continues to pull up, the suction force of the magnet 235 and the iron block 234 is not enough to resist the upward pulling force, and the lifting rod 232 begins to rise. When the lifting rod pin 233 rises, it drives the locking claw 22 to open. When the lifting rod pin 233 moves up and slides to the top of the slide slot 1 221, the locking claw 22 is fully opened.
[0081] As the drone continues to rise, gravity forces the flange rod a3 inside the buffer chamber a1 downward, compressing the spring a2. When the spring a2 reaches its limit, the drone begins to maneuver the hook mechanism 2 away from the tower crossarm 3 and returns to the ground. This completes all steps of the device's operation.
