Description

Technical Field

[0001] The invention relates to the field of electric power construction, in particular to a limiting ring installation device for adapting an anti-falling rope for tower operations. Background Art

[0002] During routine maintenance work on power transmission and transformation line towers, it is necessary to climb up to inspect the distribution lines. Before performing these operations, protective measures must be installed in advance. A common protective measure is to fix a fall prevention rope to the angle steel of the tower. The fall prevention rope is an important component that connects the safety belt and the anchor point. It is usually made of high-strength materials. In the event of a fall accident, the fall prevention rope can quickly take effect, absorb the impact force, and reduce the damage caused by the fall to the height worker. The current installation device for the fall prevention rope is shown in patent number "CN220842989U". A hanging ring is provided on the inner ring of the landing gear. The hook of the tower fall prevention device is hung in the hanging ring. The hook is set at the top of the hook. The bottom of the hook is fixedly connected to the top of the speed differential automatic controller. The fall prevention rope is set on the speed differential automatic controller. The drone hangs the hook of the fall prevention device on the angle steel of the tower, thereby completing the installation of the fall prevention rope.

[0003] After the anti-fall rope is installed, due to its long length, it is easily affected by the weather in strong winds and easily swayed, posing a safety hazard. To prevent the anti-fall rope from swaying, the current solution is to install limit rings at intervals on the foot spikes at different heights on the angle steel tower. The limit rings allow the anti-fall rope to pass through the limit rings, thereby limiting the swaying of the rope. As the length of the anti-fall rope increases, the number of limit rings required to be installed also increases. Manual installation of the limit rings requires manual climbing along the angle steel tower, which is time-consuming, labor-intensive, and extremely inefficient, and therefore needs to be solved urgently.

[0012] As a further solution of the present invention: a magnetic block is provided in the opening of the angle steel clamp away from the side of the angle steel to be clamped. When the slide is located in the opening cavity of the angle steel clamp, the positioning section of the angle steel lock tongue is magnetically attracted by the magnetic block and enters the opening cavity of the angle steel clamp, so that the angle between the angle steel lock tongue and the angle steel clamp is not less than ninety degrees; after the slide passes through the opening of the angle steel clamp and pushes the angle steel lock tongue to flip over, the angle between the angle steel lock tongue and the angle steel clamp is less than ninety degrees.

[0013] As a further solution of the present invention: the linear power source includes a pull rod arranged to slide vertically in the vertical section of the anti-fall seat, the pull rod is pulled by the lifting mechanism to produce a vertical lifting action, and a bent connecting rod is provided in the anti-fall seat, one end of the connecting rod is hingedly matched with the angle steel clamp, and the other end of the connecting rod is hingedly matched with the pull rod, and each hinge axis is parallel to the hinge axis of the angle steel lock tongue; while the pull rod moves vertically, the angle steel clamp is driven to slide along the slide seat through the connecting rod.

[0014] As a further solution of the present invention: the lifting mechanism includes a tension spring that applies a downward pulling force to the pull rod along the vertical direction in the vertical section, and a drone that applies a vertical upward pulling force to the pull rod, and the gravity of the anti-fall mechanism is greater than the elastic force of the tension spring.

[0015] As a further solution of the present invention: a pin seat located above the anti-fall seat is provided on the pull rod, and at least two groups of elastic pins are provided at intervals along the direction parallel to the axis of the angle steel clamp block at the bottom of the pin seat, and the elastic pins can float along the plumb direction; a guide hole corresponding to the plumb position of the elastic pin is opened on the anti-fall seat for the elastic pin to pass through; at least two rows of pin holes are evenly arranged along the length direction on the angle steel clamp block to correspond to the position of each elastic pin, and the pin holes in the two adjacent rows are staggered front and back, and the diameter of the elastic pin is smaller than the diameter of the pin hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention first passes the anti-fall rope through the upper guide cover, the limiting ring, the climbing rope seat and the lower guide cover on the ground, and drives the carrier cabin to climb along the anti-fall rope through the climbing rope seat. During the climbing process, when encountering the foot nails, the conical surface of the upper guide cover slides across the foot nails. After climbing to the set height, extend the telescopic guide fork to clamp and position the angle steel tower. Then rotate the swivel seat to make the limiting ring correspond to the foot nail position on the angle steel tower. Open the upper guide cover and the cabin body, so that the clamping seat of the limiting ring is clamped and fixed on the foot nail. At this time, the limiting ring is separated from the carrier cabin. After the carrier cabin moves down, close the cabin body and the upper guide cover, and return to the ground to complete the automatic installation of the limiting ring.

[0018] 2. The drone of the present invention first drives the anti-fall mechanism to rise. At this time, the extension of the tension spring reaches its maximum, the connecting rod swings upward with the rotating shaft, and drives the angle steel clamp to slide in a direction away from the pull rod. At this time, the end of the slide is located in the opening of the angle steel clamp, and the angle between the angle steel lock tongue and the angle steel clamp is a right angle or an obtuse angle. After reaching the set working height, the drone drives the anti-fall mechanism to buckle onto the angle steel from top to bottom and drives the pull rod downward. Under the action of the tension spring, the connecting rod drives the angle steel clamp to slide along the slide toward the pull rod until the end of the slide passes through the opening of the angle steel clamp. The slide pushes the angle steel lock tongue, so that the angle between it and the angle steel clamp is an acute angle. The drone drives the anti-fall mechanism downward until it is finally unlocked from the anti-fall mechanism. Under the action of the tension spring, the angle steel clamp continues to slide in the direction of the pull rod until the angle steel lock tongue abuts against the angle steel to be clamped, completing the clamping and positioning of the angle steel, thereby realizing adaptive clamping and fixing of angle steels of different sizes.

[0019] 3. The two rows of pin holes of the present invention are staggered front to back, so at least one group of elastic pins can be inserted into one of the groups of pin holes to complete the pin positioning and limit the relative sliding between the angle steel clamping block and the slide seat; through the magnetic effect of the magnetic block, the angle steel lock tongue is in the open state in the flying state, which is convenient for subsequent clamping of the angle steel from top to bottom.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] See also Figures 1 to 10 In an embodiment of the present invention, a limiting ring installation device for an anti-fall rope adapter for tower operations specifically includes the following structure:

[0043] Drone 1

[0044] The drone 1 includes a lifting base 11 arranged vertically at its base. Guide forks are arranged radially on the lifting base 11 in a cross-shaped pattern. A telescopic channel is vertically disposed within the lifting base 11. The channel is open at the bottom, and two sets of locking blocks 112 are hingedly mounted at the opening. The two sets of locking blocks 112 are arranged symmetrically, and the outer surfaces of the locking blocks 112 are provided with stepped surfaces for positioning. Locking block springs 113 are radially disposed within the telescopic channel, applying an elastic force to the locking blocks 112 to keep the stepped surfaces of the locking blocks 112 within the channel.

[0045] The drone 1 docks with the guide base 23 of the anti-fall mechanism 2 via the lifting base 11. A docking channel 231 is defined vertically within the guide base 23. A V-shaped guide fork is located at the top of the docking channel 231, allowing the lifting base 11 to be inserted into the docking channel 231. A positioning groove 232 is defined vertically on the inner wall of the docking channel 231, which serves to position the locking block 112.

[0046] A telescopic rod 111 is axially arranged in the telescopic channel. The diameter of the telescopic rod 111 is smaller than the diameter of the telescopic channel. The top surface of the locking block 112 and the bottom surface of the telescopic rod 111 are conical.

[0047] When it is necessary to complete the locking of the drone 1 and the anti-fall mechanism 2, the drone 1 first drives the lifting seat 11 downward so that the lifting seat 11 is inserted into the docking channel 231. The telescopic rod 111 is driven to extend and retract outside the telescopic channel. When the telescopic rod 111 moves downward, it pushes the locking block 112 radially outward, causing the step surface of the locking block 112 to move outward into the positioning groove 232. The drone 1 then flies upward, and the step surface of the locking block 112 abuts and positions against the positioning groove 232. At this time, the locking of the drone 1 and the anti-fall mechanism 2 is completed, and the drone 1 drives the anti-fall mechanism 2 to fly synchronously. When it is necessary to unlock the anti-fall mechanism 2 and the drone 1, the telescopic rod 111 is retracted into the telescopic channel, and the telescopic rod 111 is now out of contact with the locking block 112. Under the elastic force of the locking block spring 113, the locking block 112 resets and retracts, and disengages from the positioning groove 232. At this time, the locking block 112 is located within the projection range of the telescopic channel along the vertical direction. When the drone 1 flies upward, the lifting seat 11 disengages from the docking channel 231, completing the unlocking process.

[0048] Anti-fall mechanism 2

[0049] The anti-fall mechanism 2 includes an anti-fall seat 24, which is bent at a right angle to match the shape of the angle steel. There is a right-angled cavity inside the anti-fall seat 24. The anti-fall seat 24 includes a vertical section and a horizontal section, which form a right-angled abutment positioning for the clamped angle steel. A pull rod 21 is provided in the vertical section of the anti-fall seat 24, which passes through the anti-fall seat 24 and slides with the anti-fall seat 24. A guide seat 23 is fixed to the top of the pull rod 21 for docking and locking with the drone 1.

[0050] The pull rods 21 are symmetrically arranged in two groups, and a rotating shaft 27 is provided between the bottoms of the two pull rods 21. The rotating shaft 27 and the two pull rods 21 are rotatably matched, and the axis of rotation is arranged parallel to the angle steel to be clamped. A tension spring 26 is provided in the vertical section of the anti-fall seat 24. The tension spring 26 is arranged in the vertical direction, and its end is hung on the rotating shaft 27, thereby applying a vertical downward elastic tension to the rotating shaft 27 and the pull rods 21. The number of the tension springs 26 is preferably two groups. The overall gravity of the anti-fall seat 24 is greater than the maximum elastic tension of the tension spring 26. When the drone 1 drives the anti-fall mechanism 2 to fly upward, the tension spring 26 is in a maximum tension state, and the extension length of the pull rod 21 outside the anti-fall seat 24 is at its maximum state.

[0051] A slide 25 is horizontally arranged in the horizontal section of the anti-fall seat 24, and an angle steel clamp 244 is provided on the outer sleeve of the slide 25. The angle steel clamp 244 extends downward away from the opening at one end of the pull rod 21 and is provided with a hinged joint. The angle steel clamp 244 is hingedly provided with an angle steel locking tongue 245 through the hinged joint. The angle steel locking tongue 245 and the angle steel clamp 244 are hinged and flipped to cooperate with each other, thereby clamping the angle steel.

[0052] The bottom of the horizontal section of the anti-fall seat 24 is open, thus forming a U-shaped structure with the opening facing downward, and the opening is used as an escape channel for the action path of the angle steel lock tongue 245. A connecting rod 241 is provided on the rotation axis 27 of the pull rod 21, and the connecting rod 241 is arranged in a multi-section bent shape.

[0053] In this embodiment, the connecting rod 241 is arranged in a three-section bending shape, and the angle between adjacent bending sections is an obtuse angle. The bending sections on both sides are respectively located in the horizontal section and the vertical section of the anti-fall seat 24, and the bending section in the middle corresponds to the right-angle bending position of the anti-fall seat 24. One end of the connecting rod 241 away from the rotating shaft 27 is hingedly matched with the angle steel clamp 244. When the pull rod 21 is raised or lowered, the anti-fall seat 24 is driven to slide along the slide 25 by the connecting rod 241. A guide groove 242 is provided on the surface of the anti-fall seat 24 for the connecting rod 241 to pass through when it swings.

[0054] The hinge point of the angle steel lock tongue 245 is used as the boundary. On one side of the hinge point is the positioning section of the angle steel lock tongue 245, and on the other side of the hinge point is the clamping section of the angle steel lock tongue 245. The clamping section is used to cooperate with the angle steel clamp 244 to clamp the angle steel. The positioning section of the angle steel lock tongue 245 is shorter than the clamping section. A magnetic block 2451 is provided at the opening of the angle steel clamp 244 away from the side of the angle steel to be clamped. When the angle steel is not clamped, the magnetic block 2451 magnetically cooperates with the positioning section of the angle steel lock tongue 245, thereby rotating the positioning section of the angle steel lock tongue 245 into the opening of the angle steel clamp 244. Under the magnetic attraction, the angle between the angle steel lock tongue 245 and the angle steel clamp 244 is a right angle or an obtuse angle. When the end of the slide 25 passes through the opening of the angle steel clamp 244, the angle steel locking tongue 245 rotates under the pushing action of the slide 25. At this time, the angle steel locking tongue 245 and the angle steel clamp 244 form an acute angle. In this embodiment, when the slide 25 is located in the opening of the angle steel clamp 244, the contact surface between the angle steel locking tongue 245 and the slide 25 is in a vertical state. After the slide 25 passes through the opening of the angle steel clamp 244 and contacts the angle steel locking tongue 245, the contact surface between the angle steel locking tongue 245 and the slide 25 is in a horizontal state.

[0055] During the actual working process, the drone 1 first drives the anti-fall mechanism 2 to rise. At this time, the elongation of the tension spring 26 reaches the maximum, the connecting rod 241 swings upward with the rotating shaft 27, and drives the angle steel clamp 244 to slide in the direction away from the pull rod 21. At this time, the end of the slide 25 is located in the open cavity of the angle steel clamp 244, and the angle between the angle steel lock tongue 245 and the angle steel clamp 244 is a right angle or an obtuse angle. After reaching the set working height, the drone 1 drives the anti-fall mechanism 2 to buckle onto the angle steel from top to bottom, and drives the pull rod 21 downward. Under the action of the tension spring 26, the connecting rod 241 drives the angle steel clamp 244 to slide along the slide 25 toward the pull rod 241 until the end of the slide 25 passes through the opening of the angle steel clamp 244, and pushes the angle steel lock tongue 245 through the slide 25, so that the angle between it and the angle steel clamp 244 is acute. The drone 1 drives the anti-fall mechanism 2 to move downward until it is finally unlocked from the anti-fall mechanism 2. Under the action of the tension spring 26, the angle steel clamp 244 continues to slide toward the pull rod 21 until the angle steel lock tongue 245 abuts against the angle steel to be clamped, completing the clamping and positioning of the angle steel.

[0056] To improve clamping stability, the pull rod 21 is connected to the guide base 23 via the latch base 22. The bottom of the latch base 22 is equipped with two sets of elastic latches 221 that can elastically float up and down in the vertical direction. The line connecting the two elastic latches 221 is arranged parallel to the rotation axis 27. The angle steel clamp 244 is evenly distributed along the length of the two rows of latch holes 2441, and the two rows of latch holes 2441 are staggered front and back. The anti-fall base 24 is provided with guide holes 243 corresponding to the vertical position of the elastic latches 221 for the elastic latches 221 to pass through. After the angle steel is clamped and positioned, the latch seat 22 abuts against the anti-fall seat 24. At this time, the elastic latch 221 passes through the guide hole 243 and is inserted into the elastic latch 221. Since the two rows of latch holes 2441 are staggered front and back, at least one group of elastic latches 221 can be inserted into one group of latch holes 2441 to complete the latch positioning and limit the relative sliding between the angle steel clamp 244 and the slide seat 25.

[0057] Anti-fall rope 3

[0058] The anti-fall rope 3 is directly hung on the bottom of the anti-fall seat 24 through a hook or other locking parts, so that it is transported to the set working height by the drone 1 together with the anti-fall mechanism 2.

[0059] Carrier 4

[0060] The carrier cabin 4 includes a swivel base 42, which consists of a rotating end and a non-rotating end. A lower guide hood 422 is provided at the bottom of the non-rotating end of the swivel base 42. The lower guide hood 422 has a conical structure with the tip arranged downward. Telescopic guide forks 421 are evenly arranged radially along the non-rotating end of the swivel base 42. Preferably, four sets of telescopic guide forks 421 are provided, capable of performing telescopic movements radially along the swivel base 42. When the telescopic guide forks 421 are not in operation, they are fully retracted into the interior of the swivel base 42. When the carrier cabin 4 needs to be positioned, the telescopic guide forks 421 are extended. Two sets of telescopic guide forks 421 clamp and position themselves with the angle steel tower, thereby limiting the rotational movement of the non-rotating end of the carrier cabin 4.

[0061] Two sets of rocker arms 44 are symmetrically arranged on the rotating end of the swivel seat 42, and the hinge axes of the rocker arms 44 are arranged horizontally. Each rocker arm 44 is provided with a set of split cabins, which form a columnar cabin body when the split cabins on the two rocker arms 44 are closed, and the limit ring 5 is arranged inside the cabin body.

[0062] The two separate compartments of the carrier compartment 4 are each topped with a separate guide hood. When the compartments are closed, the two separate guide hoods also close to form an upper guide hood 41, symmetrically arranged above and below the lower guide hood 422. When the swing arm 44 is driven by a motor or gear, it rotates, driving the compartments to open and close from top to bottom, revealing the retaining ring 5 within the compartment. A power source can be added to the separate guide hoods to independently open and close the upper guide hood 41.

[0063] A rope climbing seat 43 is also fixed within the carrier cabin 4. This seat uses an existing rope climbing mechanism, which allows for climbing along the anti-fall rope using friction or an inchworm-like climbing mechanism. Its structure is omitted for clarity. The anti-fall rope 3 passes axially through the upper guide cover 41, the rope climbing seat 43, and the lower guide cover 422.

[0064] During operation, first pass the anti-fall rope through the upper guide cover 41, the limiting ring 5, the climbing rope seat 43 and the lower guide cover 422 on the ground, and drive the carrier cabin 4 to climb along the anti-fall rope 3 through the climbing rope seat 43. During the climbing process, when encountering the foot nails, slide through the conical surface of the upper guide cover 41 and the foot nails. After climbing to the set height, extend the telescopic guide fork 421 to clamp and position the angle steel tower. Then rotate the swivel seat to make the limiting ring 5 correspond to the position of the foot nails on the angle steel tower. Open the upper guide cover 41 and the cabin body so that the clamping seat 54 of the limiting ring 5 is clamped and fixed on the foot nail. At this time, the limiting ring 5 is separated from the carrier cabin 4. After the carrier cabin 4 moves down, close the cabin body and the upper guide cover 41, and return to the ground to complete the installation of the limiting ring 5.

[0065] Limiting ring 5

[0066] The retaining ring 5 comprises a vertically arranged connecting rod 51, to which are fixed coaxially an upper retaining ring 52 and a lower retaining ring 53. Both the upper and lower retaining rings 52 and 53 have notches for the passage of the rope, with the notches facing in opposite directions. These two sets of notches allow the safety rope 3 to be smoothly inserted into the retaining rings while on the ground, while the opposite notches prevent the rope 3 from escaping from the retaining rings 5.

[0067] The connecting rod 51 is also provided with a clamping seat 54 for clamping the foot spike, and the clamping seat 54 is vertically offset from the upper limit ring 52 and the lower limit ring 53. The clamping seat 54 clamps and fixes the foot spike by opening and closing.

[0074] S6. Close the carrying cabin 4 and allow the user to climb down along the anti-fall rope 3. After the carrying cabin 4 is recovered, the installation is completed.

[0075] According to the different heights of the angle steel tower, steps S4 to S6 are repeated to install the limiting rings 5 ​​at different height intervals to ensure the stability of the anti-fall rope 3.
