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 pole tower operations. Background Art

[0002] During the daily maintenance work of the power transmission and transformation line tower, it is necessary to climb up to inspect the distribution line. Before the climbing work, it is necessary to install protective measures in advance. The commonly used protective measures are to fix the anti-fall rope on the angle steel of the tower. The anti-fall rope is an important component connecting the safety belt and the anchor point. It is usually made of high-strength materials. In the event of a fall accident, the anti-fall rope can quickly play a role, absorb the impact force, and reduce the damage caused by the fall to the high-altitude workers. The current installation device of the anti-fall rope is shown in the patent number "CN220842989U". A hanging ring is set on the inner ring of the landing gear. The hook of the tower anti-fall 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 difference automatic controller. The anti-fall rope is set on the speed difference automatic controller. The drone hangs the hook of the anti-fall device on the angle steel of the tower, thereby completing the installation of the anti-fall rope.

[0003] After the anti-fall rope is installed, due to its long length, it is very easy to shake under the influence of bad weather in windy weather, which poses a safety hazard. To prevent the anti-fall rope from shaking, the current solution is to set limit rings on the foot nails at different heights on the angle steel tower, so that the anti-fall rope passes through the limit rings, and the limit rings are used to limit the shaking of the anti-fall rope. As the length of the anti-fall rope increases, the number of limit rings that need to be installed also increases. It is necessary to rely on manual climbing along the angle steel tower to manually install the limit rings, which is time-consuming, labor-intensive and extremely inefficient, so it needs to be solved urgently.

[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 through the foot nails alternately. After climbing to the set height, extend the telescopic guide fork to clamp and position the angle steel tower.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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-falling rope adapter for a pole tower operation specifically includes the following structure:

[0043] Drone 1

[0044] The drone 1 includes a lifting seat 11 arranged along a vertical direction at the bottom of the drone 1, and a cross-staggered guide fork is arranged radially on the lifting seat 11. A telescopic channel is vertically arranged in the lifting seat 11, and the bottom of the telescopic channel is open. Two groups of locking blocks 112 are hingedly arranged at the opening. The two groups of locking blocks 112 are arranged symmetrically on the left and right, and the outer side surfaces of the locking blocks 112 are provided with step surfaces for positioning. A locking block spring 113 is radially arranged in the telescopic channel, and the locking block spring 113 applies elastic force to the locking block 112 so that the step surface of the locking block 112 is located in the telescopic channel.

[0045] The drone 1 is docked with the guide seat 23 of the anti-fall mechanism 2 through the lifting seat 11. A docking channel 231 is provided in the guide seat 23 along the vertical direction. A guide fork with a V-shaped opening is provided at the top of the docking channel 231 for the lifting seat 11 to be inserted into the docking channel 231. A positioning groove 232 is provided on the inner wall of the docking channel 231 along the vertical direction. The positioning groove 232 is used 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, and 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 to move 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 outward in the radial direction, so that the step surface of the locking block 112 moves outward to the positioning groove 232. Then the drone 1 flies upward, and the step surface of the locking block 112 abuts and positions with 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 at this time, the telescopic rod 111 is out of contact with the locking block 112. Under the elastic force of the lock block spring 113, the lock block 112 resets and retracts, and disengages from the positioning groove 232. At this time, the lock 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, and there is a right-angled cavity inside the anti-fall seat 24. The anti-fall seat 24 includes a plumb section and a horizontal section to form a right-angle abutment positioning for the clamped angle steel. A pull rod 21 is provided in the plumb section of the anti-fall seat 24, which passes through the anti-fall seat 24 and slides with the anti-fall seat 24, and a guide seat 23 is fixed on the top of the pull rod 21 for docking and locking with the drone 1.

[0050] The pull rod 21 is symmetrically arranged in two groups, and a rotating shaft 27 is arranged between the bottoms of the two pull rods 21. The rotating shaft 27 is rotatably matched with the two pull rods 21, and the rotation axis is arranged in parallel with the angle steel to be clamped. A tension spring 26 is arranged 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, so as to apply a vertical downward elastic tension to the rotating shaft 27 and the pull rod 21, and the number 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 the maximum tension state, and at this time, the extension length of the pull rod 21 outside the anti-fall seat 24 is in the maximum state.

[0051] A sliding seat 25 is horizontally arranged in the horizontal section of the anti-fall seat 24, and an outer sleeve of the sliding seat 25 is provided with an angle steel clamp 244. The angle steel clamp 244 is downwardly extended 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 is hingedly flipped and matched with the angle steel clamp 244 to clamp 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 passage for the action path of the angle steel lock tongue 245. A connecting rod 241 is arranged 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 hinged 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 seat 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 swinging.

[0054] Taking the hinge point of the angle steel lock tongue 245 as the boundary, one side of the hinge point is the positioning section of the angle steel lock tongue 245, and the other side of the hinge point is the clamping section of the angle steel lock tongue 245, and the clamping section is used to cooperate with the angle steel clamp block 244 to clamp the angle steel. The length of the positioning section of the angle steel lock tongue 245 is less than the length of the clamping section, and a magnetic block 2451 is provided at the opening of the angle steel clamp block 244 away from the side of the angle steel to be clamped. In the non-clamping angle steel state, the magnetic block 2451 cooperates with the positioning section of the angle steel lock tongue 245 by magnetic attraction, so that the positioning section of the angle steel lock tongue 245 rotates into the opening of the angle steel clamp block 244, and under the magnetic attraction, the angle between the angle steel lock tongue 245 and the angle steel clamp block 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 lock tongue 245 rotates under the pushing action of the slide 25, and the angle between the angle steel lock tongue 245 and the angle steel clamp 244 is 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 lock tongue 245 and the slide 25 is in a vertical state, and after the slide 25 passes through the opening of the angle steel clamp 244 and contacts the angle steel lock tongue 245, the contact surface between the angle steel lock 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 seat 25 is located in the opening 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 the angle steel locking tongue 245 is pushed by the slide 25, so that the angle between it and the angle steel clamp 244 is acute. After the drone 1 drives the anti-fall mechanism 2 to move downward until it is finally unlocked with 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 locking tongue 245 abuts against the angle steel to be clamped, completing the clamping and positioning of the angle steel.

[0056] In order to improve the stability of clamping, the pull rod 21 is connected to the guide seat 23 through the pin seat 22. Two groups of elastic pins 221 that can float elastically up and down in the vertical direction are arranged at the bottom of the pin seat 22. The connecting line between the two elastic pins 221 is arranged parallel to the rotating shaft 27. Two rows of pin holes 2441 are evenly arranged along the length direction on the angle steel clamp block 244, and the two rows of pin holes 2441 are arranged front and back staggered. The anti-fall seat 24 is provided with a guide hole 243 corresponding to the vertical position of the elastic pin 221 for the elastic pin 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 seat 42, which is composed of a rotating end and a non-rotating end. A lower guide cover 422 is provided at the bottom of the non-rotating end of the swivel seat 42. The lower guide cover 422 is a conical structure with the tip arranged downward. Telescopic guide forks 421 are evenly arranged radially along the inner side of the non-rotating end of the swivel seat 42. The telescopic guide forks 421 are preferably arranged in four groups, which can produce telescopic movements along the radial direction of the swivel seat 42. The telescopic guide forks 421 are completely retracted into the inside of the swivel seat 42 in the non-working state. When the position of the carrier cabin 4 needs to be positioned, the telescopic guide forks 421 are extended, and two groups of telescopic guide forks 421 are clamped and positioned with the tower body of the angle steel tower, thereby limiting the rotation and shaking of the non-rotating end of the carrier cabin 4.

[0061] Two sets of swing rods 44 are symmetrically arranged on the rotating end of the swivel seat 42, and the hinge axis of the swing rods 44 is arranged horizontally. A set of split cabins are arranged on each of the two swing rods 44, and the split cabins on the two swing rods 44 are closed to form a columnar cabin body, and the limit ring 5 is arranged inside the cabin body.

[0062] A group of split guide covers are also provided on the top of the two groups of split cabins of the carrier cabin 4. When the cabins are closed, the two groups of split guide covers are also closed to form an upper guide cover 41. The upper guide cover 41 and the lower guide cover 422 are arranged symmetrically up and down. When the swing rod 44 is driven by a motor or a gear to rotate, it drives the cabin to open and close from top to bottom, and after unfolding, the limit ring 5 in the cabin is exposed. A group of power sources can be added to the split guide covers to open the upper guide cover 41 separately, so that the upper guide cover 41 can have an independent opening and closing action.

[0063] A rope climbing seat 43 is also fixed in the cabin of the carrier cabin 4. The rope climbing seat 43 uses an existing rope climbing mechanism, and can climb along the anti-fall rope by friction climbing rope or inchworm climbing mechanism. The structure is not repeated. The anti-fall rope 3 passes through the upper guide cover 41, the rope climbing seat 43 and the lower guide cover 422 in sequence along the axial direction of the carrier cabin 4.

[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, the conical surface of the upper guide cover 41 slides through the foot nails alternately. 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 foot nail position 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 limit ring 5 includes a connecting rod 51 arranged in the vertical direction, and an upper limit ring 52 and a lower limit ring 53 arranged coaxially are fixed on the connecting rod 51. The upper limit ring 52 and the lower limit ring 53 are both provided with notches for the rope to pass through, and the notches are in opposite directions. Through the two sets of notches, the anti-fall rope 3 can be smoothly placed in the limit ring when on the ground, and the opposite notches can prevent the anti-fall rope 3 from escaping from the limit ring 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 arranged with 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.
