Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power cable installation, in particular to a power installation high-altitude anti-falling device. BACKGROUND

[0002] In the construction of power systems, the laying and installation of high-altitude cables is a risky and technically complex operation. Construction personnel and cable equipment often need to move between dozens of meters or even higher towers, canyons or complex terrains, facing a high risk of falling from a great height. Traditional safety measures mainly rely on personal anti-falling devices worn by construction personnel, which have limited protection range and cannot effectively prevent high-speed falling accidents caused by accidental breakage or unhooking of heavy cables, tools or equipment during traction. Such accidents not only cause huge economic losses and delay project progress, but also seriously threaten the safety of ground personnel and facilities.

[0003] To address this challenge, the industry has developed a variety of load carriers or auxiliary traction devices that run along a pre-set wire rope. However, the existing technology still has many obvious defects in practical application:

[0004] Firstly, the mounting and dismounting of the device on the wire rope is often cumbersome, requiring multiple people to cooperate or using special tools, which is inefficient and increases the risk in high-altitude environments. Secondly, the existing devices use fixed structures for wire rope clamping and driving, which are difficult to adapt to wire ropes of different diameters, different tensions and inclined paths, leading to uneven force distribution on the wheel set, increased wear and tear, and even slipping and jamming when the slope is large, affecting the stability and reliability of movement. Thirdly, most devices have single functions and can only achieve load movement, lacking the ability to flexibly and accurately fine-tune the installation position of the cable, often requiring additional hoisting equipment to operate, which is complex. More importantly, the safety protection mechanism of the existing technology is generally passive and slow to respond, usually using pure mechanical friction braking or electromagnetic braking, which has a fixed triggering threshold and cannot sensitively identify the instantaneous high-speed sliding of the cable due to breakage. The braking has a lag and cannot effectively stop the heavy object from falling in a very short time.

[0005] In addition, the power supply and control lines of the existing device are usually external towlines, which are prone to entanglement and pulling when the device moves and changes position, affecting operation and posing safety hazards. The overall structure of the device is often designed as a whole, making it difficult to maintain and replace when damaged, increasing the use cost throughout the life cycle.

[0006] The present application aims to solve the technical problems existing in the prior art, and proposes a power installation high-altitude anti-falling device. SUMMARY

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. Easy to mount and stable and reliable to move.

[0026] The equipment can be quickly mounted on a pre-erected wire rope by being guided by the inclined guide plate and the inclined connecting plate. The drive traction wheel and the movable guide wheel work together to carry the equipment and move it along the wire rope. The position of the movable guide wheel is pre-tightened by the spring and the adjusting nut to keep each wheel in a balanced fit with the wire rope, adapting to different load and inclination conditions, reducing wear and ensuring stable operation over a long period of time.

[0027] 2. Highly adaptable and flexible.

[0028] The guide mounting plate and movable guide wheels adopt a modular design, and their quantity can be increased or decreased according to actual working conditions; the spring buffer mechanism enables the equipment to maintain good fit and force distribution when the load changes or the angle of the wire rope changes, improving the adaptability of the equipment to different installation paths and cable specifications.

[0029] 3. Precise displacement adjustment and simple power supply integration

[0030] The displacement adjustment mechanism controls the length of the traction rope by driving the winding device, so as to realize the smooth sliding of the displacement guide installation cylinder along the limit guide installation column and meet the adjustment needs of different installation positions; the power supply guide rail and the power supply guide groove achieve coupling power supply during sliding, eliminating the cumbersome external cable and improving the convenience and safety of operation.

[0031] 4. Highly effective fall protection and rapid response.

[0032] The cable fall prevention mechanism uses a combination of a load-bearing guide wheel and a limit guide wheel to press the cable. When the cable breaks accidentally or the traction becomes unbalanced, the speed of the load-bearing guide wheel increases sharply. Through centrifugal force, the arc-shaped rotating belt unfolds and the striking column hits the movable mounting block, which eventually brakes the limit guide wheel, quickly decelerates and locks the cable, effectively preventing falls from heights.

[0033] 5. Adjustable braking threshold, wide range of applications

[0034] By adjusting the pressure inside the deformation airbag with an air pump, the initial curvature of the arc-shaped rotating belt can be changed, thereby flexibly setting the cable sliding speed required to trigger braking and adapting to the safety protection needs of cables of different sizes and weights.

[0035] 6. Modular structure, easy maintenance

[0036] All major components, such as guide mounting plates, drive winding machines, and combination mounting plates, are detachable, facilitating quick replacement, repair, and maintenance, thereby reducing equipment maintenance costs and downtime.

[0037] 7. Multi-stage cascading enhances overall safety.

[0038] The equipment supports the use of multiple units in series, forming segmented protection in long-distance cable installations, further reducing the possibility of the entire cable falling, and significantly enhancing system safety. Attached Figure Description

[0057] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0058] Example 1, please refer to Figures 1-8 In this embodiment of the invention, a high-altitude fall protection device for power installation includes a steel wire rope 1, and further includes: a guiding movement mechanism, a displacement adjustment mechanism, and a cable fall protection mechanism.

[0059] The guiding and moving mechanism includes a bearing mounting plate 2 and a limiting mounting plate 3 facing each other. A hanging mounting plate 10 is vertically arranged directly below the bearing mounting plate 2 and the limiting mounting plate 3. The lower end of the bearing mounting plate 2 is connected to the hanging mounting plate 10 through an inclined connecting plate 6. An inclined guide plate 5 is provided at the lower end of the limiting mounting plate 3. The inclined guide plate 5 and the inclined connecting plate 6 are parallel.

[0060] Both ends of the bearing mounting plate 2 and the limiting mounting plate 3 are provided with rotating bearing sleeves 36 facing each other, and a drive traction wheel 4 is provided between the rotating bearing sleeves 36 facing each other through a rotating shaft.

[0061] The upper ends of the load-bearing mounting plate 2 and the limiting mounting plate 3 between the drive traction wheels 4 are provided with several guide mounting grooves 18 at equal intervals. Each guide mounting plate 12 is provided in conjunction with the guide mounting groove 18. Movable guide wheels 11 are provided between the opposite guide mounting plates 12 through a rotating shaft. The guide mounting plate 12 is provided with a rotating bearing sleeve 36 in conjunction with the rotating shaft.

[0062] U-shaped reinforcing plates 9 are connected to the upper ends of the load-bearing mounting plate 2 and the limiting mounting plate 3 between the movable guide wheels 11 and between the drive traction wheel 4 and the movable guide wheels 11;

[0063] The guide mounting plate 12 is symmetrically provided with limit sliders 46 at both ends, and the inner side of the guide mounting groove 18 is provided with limit grooves 20 to cooperate with the limit sliders 46.

[0064] The guide mounting plate 12 is symmetrically provided with guide mounting holes 50. The bottom of the guide mounting groove 18 directly opposite the guide mounting hole 50 is provided with a fixing screw hole 19. A guide stud 47 is provided in conjunction with the guide mounting hole 50. Both ends of the guide stud 47 are provided with external threads 48. The external thread 48 at one end is provided with the fixing screw hole 19, and the external thread 48 at the other end is provided with an adjusting nut 51. A spring 49 is sleeved on the outside of the guide stud 47 between the adjusting nut 51 and the guide mounting plate 12. A spring 49 is also sleeved on the outside of the guide stud 47 between the fixing screw hole 19 and the guide mounting plate 12.

[0065] According to the installation path of the power cable, the wire rope 1 is pre-erected and fixed. Then, the equipment is hung on the erected wire rope 1. Specifically, the inclined guide plate 5 and the inclined connecting plate 6 are used to allow the wire rope 1 to slide between the bearing mounting plate 2 and the limiting mounting plate 3 until the drive traction wheel 4 and the movable guide wheel 11 contact the wire rope 1, completing the mounting of the equipment. The equipment is moved by driving the traction wheel 4, and the cable on the cable anti-fall mechanism moves synchronously. The mounting and dismounting are quick and simple.

[0066] According to the load capacity of the power cable and the angle of the wire rope 1, a corresponding number of movable guide wheels 11 can be selected for installation and adjustment. Specifically, with the cooperation of the limit slider 46 and the limit groove 20, the guide mounting plate 12 is inserted into the guide mounting groove 18, and a corresponding number of guide studs 47 are inserted into the guide mounting holes 50. Springs 49 are fitted on the guide studs 47 on both sides of the guide mounting holes 50. First, the guide studs are rotated so that the external threads 48 at their ends cooperate with the fixing screw holes 19 to fix the guide studs 47. Then, the adjusting nut 51 is rotated to adjust the position of the guide mounting plate 12 in the initial state. Different initial positions of the guide mounting plate 12 correspond to different lengths of springs 49, and the deformation space is also different under different loads and different moving angles. Finally, when the equipment moves under load on the wire rope 1, the movable guide wheels 11, the drive traction wheels 4 and the wire rope 1 have good contact and balanced force, reducing the wear of the movable guide wheels 11 and the drive traction wheels 4, and ensuring the stable movement of the equipment for a long time.

[0067] Example 2, based on Example 1, please refer to... Figures 1-5 and Figures 8-13 In this embodiment of the invention, the displacement adjustment mechanism includes a limiting guide mounting column 7 horizontally arranged at the lower end of the mounting plate 10, and a displacement guide mounting cylinder 8 is provided in cooperation with the limiting guide mounting column 7;

[0068] The limiting guide mounting post 7 has symmetrically arranged combined mounting plates 37 at both ends. A combined mounting stud 38 is provided on one side of the combined mounting plate 37. Both ends of the limiting guide mounting post 7 are provided with combined mounting screw holes 16 to cooperate with the combined mounting stud 38. A drive winding device 13 is fixedly installed on the other side of the combined mounting plate 37. A traction rope 22 is provided extending from the lower end of the drive winding device 13.

[0069] The lower side of the limiting guide mounting column 7 is symmetrically provided with power supply guide grooves 17, and the inner side of the displacement guide mounting cylinder 8 is provided with power supply guide rails 21 in conjunction with the power supply guide grooves 17.

[0070] When the equipment moves to the target position, the length of the traction rope 22 is adjusted by the drive winder 13, so that the displacement guide mounting cylinder 8 and the limit guide mounting column 7 can slide and move. During the sliding and moving process, the power supply guide rail 21 and the power supply guide groove 17 slide and cooperate to achieve coupled power supply.

[0071] By combining the mounting studs 38 and the mounting screw holes 16, the mounting plate 37 can be quickly installed and removed, enabling the drive winding device 13 to be quickly replaced and maintained.

[0072] Example 3, based on Example 2, please refer to... Figure 1 , Figure 2 , Figures 9-15 In this embodiment of the invention, the cable fall prevention mechanism includes a C-shaped mounting bracket 14, one end of which is fixed to the lower end of the displacement guide mounting cylinder 8, and a bearing guide wheel 15 is rotatably provided at the lower end of the C-shaped mounting bracket 14.

[0073] The two ends of the bearing guide wheel 15 are respectively provided with a bearing limiting rotating column 33 and a synchronous rotating column 23 at the middle position. The lower end of the C-shaped mounting bracket 14 is provided with a bearing limiting rotating sleeve 34 in conjunction with the bearing limiting rotating column 33.

[0074] The upper end of the C-shaped mounting bracket 14 is vertically equipped with a drive telescopic column 24. An adjusting mounting bracket 25 is located at the end of the drive telescopic column 24. A rotating swing arm 26 is symmetrically arranged at the lower end of the adjusting mounting bracket 25. One end of the rotating swing arm 26 is mounted on the adjusting mounting bracket 25 via a reset shaft 29. The other end of the rotating swing arm 26 is equipped with a swing mounting bracket 30. Each swing mounting bracket 30 is rotatably equipped with a limit guide wheel 27. Both ends of the limit guide wheel 27 are symmetrically equipped with follow-up limit shafts 32. The follower limit rotating shaft 32 at one end is coaxially provided with a follower turntable 40. The two ends of the swing mounting frame 30 are provided with follower limit bearing sleeves 31 in cooperation with the follower limit rotating shaft 32. The follower limit bearing sleeve 31 at one end is provided with a follower mounting cylinder 28 in cooperation with the follower turntable 40. The cylinder wall of the follower mounting cylinder 28 is symmetrically provided with movable mounting holes 41. Movable mounting blocks 42 are provided in cooperation with the movable mounting holes 41. Several limit protrusions 43 are provided on the outer side of the follower turntable 40 and the inner side of the movable mounting block 42.

[0075] An arc-shaped rotating belt 45 is provided on the outer side of the synchronous rotating column 23, and a striking column 44 is provided on the outer side of the arc-shaped rotating belt 45. Several deformation airbags 39 are provided inside the arc-shaped rotating belt 45.

[0076] An air pump 35 is provided at one end of the bearing limiting rotating column 33 that extends out of the bearing limiting rotating sleeve 34. A flow guide cavity 52 is provided in the bearing limiting rotating column 33, the bearing guide wheel 15 and the synchronous rotating column 23. One end of the flow guide cavity 52 is connected to the air pump 35 and the other end of the flow guide cavity 52 is connected to the deformation airbag 39.

[0077] By retracting the telescopic column 24, the adjusting mounting frame 25 is raised, causing the rotating arm 26, the swing mounting frame 30, and the limiting guide wheel 27 on it to rise synchronously. At this time, the power cable to be installed is placed on the bearing guide wheel 15. Then, the telescopic column 24 is extended, causing the adjusting mounting frame 25 to move downward until the limiting guide wheel 27 contacts the power cable. The adjusting mounting frame 25 then descends further, causing the rotating arm 26 to rotate around the reset shaft 29 at a certain angle, so that the limiting guide wheel 27 can always be in contact with the power cable, preventing the power cable from falling off the bearing guide wheel 15 and ensuring the continuous and stable installation process of the power cable.

[0078] With the rotational cooperation of the follower limit rotating shaft 32 and the follower limit bearing sleeve 31, the continuous and stable rotation of the limit guide wheel 27 is ensured. At the same time, with the rotational cooperation of the bearing limit rotating column 33 and the bearing limit rotating sleeve 34, the continuous and stable rotation of the bearing guide wheel 15 is ensured.

[0079] When the power cable breaks abnormally, the power cable on one side of the bearing guide wheel 15 becomes unbalanced and moves rapidly from one side of the bearing guide wheel 15 to the other. At this time, the rotation speed of the bearing guide wheel 15 and its synchronous rotating column 23 increases significantly, causing the arc-shaped rotating belt 45 on the synchronous rotating column 23, along with the striking column 44, to rotate at high speed. Under the action of centrifugal force, the curvature of the arc-shaped rotating belt 45 decreases, and the rotation radius of the striking column 44 increases until it impacts the movable mounting block 42, causing the movable mounting block 42 to move along the movable mounting hole 41 toward the follower mounting cylinder 2. 8. Internal movement: When the limiting protrusion 43 on the movable mounting block 42 contacts, decelerates, and finally engages with the limiting protrusion 43 on the follower turntable 40, the limiting guide wheel 27 finally stops rotating. At this time, the power cable passes through the equipment and is subjected to the friction of the limiting guide wheel 27 and the reset pressure of the reset shaft 29, which significantly reduces the speed of the power cable until the power cable stops completely. This prevents the power cable from falling when it breaks abnormally or loses traction during the installation of high-altitude power cables, significantly improving the safety of the equipment. Multiple sets of this equipment installed in series can further improve safety.

[0080] The air pump 35 is started to adjust the pressure inside the deformation airbag 39 by adjusting the flow guide cavity 52, thereby changing the curvature of the arc rotating belt 45 in the initial state, thereby adjusting the rotation speed of the bearing guide wheel 15 when the limit guide wheel 27 is locked, so as to adapt to the installation requirements of power cables of different sizes.
