Description

Technical Field

[0001] The invention relates to the technical field of routing operations for extra-high voltage and ultra-high voltage transmission conductors, and in particular to a routing operation auxiliary device for multi-split transmission lines. Background Art

[0002] At present, the routing operations of ultra-high voltage and UHV transmission lines are of irreplaceable importance in the field of power transmission, especially in special environments such as line acceptance and live operations. They can effectively make up for the blind spots and visual blind spots of machine patrol cameras and accurately detect subtle defects in transmission lines.

[0003] Existing line-walking operations lack professional tools, and workers' hands are often injured by wire barbs, which poses a high risk of personal injury. In order to solve this problem, a walking assistance device for multi-split transmission line conductors represented by ultra-high voltage and UHV transmission lines has been developed in this field. A long shaft is used with rollers added at both ends of the long shaft. When walking, the rollers roll forward along the transmission wire, and the worker pushes forward by holding the long shaft, which effectively avoids damage caused by hand contact with the wire and improves the stability of travel.

[0004] The existing safety tools for walking on power transmission lines are mainly safety belts, but safety belts can only prevent people from falling from high altitudes. After a worker falls, he or she can hardly save himself or herself and can only hang in the air and wait for rescue. When a worker falls, due to the effect of gravity, the physical impact of the safety belt on the worker is almost unbearable for ordinary people. This situation is also very likely to cause the risk of collision between the worker and the tower in the steep slope section of the line. While waiting for rescue, the worker is often suspended in the air, which often causes ischemia in his or her legs. When facing extreme working environments such as high temperature or severe cold, his or her life safety is seriously threatened.

[0005] In addition, most of the existing power transmission line walking tools are large equipment such as routing robots and routing bicycles. The root pain points such as large size, heavy weight, and difficult operation make such innovative results almost unacceptable to front-line personnel. At the same time, there are many devices and operation processes that need to be carried during high-altitude operations, and frequent searches for tools make the routing operations extremely busy and inefficient. Various scattered instruments need to be carried by operators themselves, which increases the burden on staff and is also very inconvenient to take. Summary of the invention

[0018] Furthermore, the brake assembly includes a second clamping component and a bracket, the second clamping component is L-shaped, the top of the second clamping component is rotatably connected to one end of the push rod through the cooperation of a rotating shaft and an elongated circular hole, the middle part of the second clamping component is rotatably connected to the bottom of the bracket through the rotating shaft, and the top of the bracket is fixed to the bottom of the long shaft by bolts.

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings. The following embodiments are only specific embodiments exemplified in this application, which are used to illustrate the technical solution of the present application, rather than to limit it, and the scope of protection of the present application is not limited thereto. In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] The present invention provides a multi-split transmission line routing operation auxiliary device, comprising a long shaft 1, a roller module 2, a limit module 3, a brake module 4 and a safety rope, see Figure 1-3 shown.

[0042] In order to facilitate the smooth passage of the spacer bar, save manpower and improve efficiency, the roller module 2 includes climbing wheels arranged on both sides of the long axis 1. Specifically, the climbing wheel 2 includes a triangular plate 21 and three rollers 22. The triangular plate 21 is rotatably connected to the long axis 1 through a bearing, and the three rollers 22 are respectively installed at the three corners of the triangular plate 21. The three rollers act alternately, which facilitates the smooth passage of the spacer bar, saves manpower and improves efficiency. The roller 22 is circumferentially formed with a slide groove 23 for accommodating the transmission wire, and the transmission wire can be embedded in the slide groove 23, so that the device can walk stably on the ultra-high voltage and ultra-high voltage transmission wires. In a preferred embodiment, in order to improve durability, the roller 22 is connected to the triangular plate 21 through a deep groove ball bearing 24 with sealing rings on both sides. Roller 1 can also use damping to further ensure walking stability.

[0043] In order to realize the dual braking functions of active braking and passive braking, active braking can ensure the safe movement of workers on a sloping line, and passive braking can assist people who fall and slip to brake on the spot, avoiding secondary injuries caused by people sliding along the slope of the line and colliding with the tower when people fall and slip, the limiting module 3 and the braking module 4 are respectively arranged in two groups, one limiting module 3 and one braking module 4 are a group, and are respectively arranged on both sides of the climbing wheel; the limiting module 3 limits the transmission wire in the slide groove 23 of the climbing wheel through the first clamping component 31 and the roller 34 at its end to prevent the transmission wire from falling out.

[0044] Specifically, the limiting module 3 includes a first holding component 31, a bracket 32, a slide bar 33, a second roller 34 and a torsion spring 35 (such as Figure 4 The top of the bracket 32 ​​is fixed to the bottom of the long shaft 1 by bolts, and the top of the first clamping member 31 has a slot 36 (as shown in FIG. Figure 5 The middle part of the first clamping part 31 is rotatably connected to the bottom of the bracket 32 ​​through a rotating shaft; the torsion spring 35 is wound on the rotating shaft, one free end of the torsion spring 35 abuts against the bracket 32, and the other free end of the torsion spring 35 abuts against the first clamping part 31, and the spring 35 applies elastic force in the direction away from the roller 22; the two ends of the slide rod 33 move up and down in the long round hole of the bracket 32; the rod body of the slide rod 33 can be downwardly embedded in the card slot at the top of the first clamping part 31, thereby realizing The first clamping component 31 limits the transmission wire in the slide groove 23 of roller one 22, and at the same time realizes the rolling friction between the limiting module and the transmission wire through roller two 34 of the first clamping component 31, thereby reducing the friction force while limiting and ensuring the smooth passage of the transmission wire; after the rod body of the slide rod 33 is lifted up and leaves the slot, the first clamping component 31 can be rotated along the rotating shaft on the bracket 32 ​​under the action of the torsion spring 35 and then opened, so that the three rollers can act alternately and then pass the spacer rod smoothly.

[0045] The brake module 4 includes a second clamping component 41, a bracket 42, a pressure plate 43, a brake shoe 44, a push rod 45, a connecting rod 46, a wrench 47, a safety rope hanging ring 48 and a safety rope lifting ring 49. The brake module 4 clamps the power transmission wire and the roller 22 through the wrench 47, the push rod 45 and the second clamping component 41; a safety rope hanging ring 48 is formed at the end of the wrench 47 away from the connecting rod 46, and two safety rope lifting rings 49 are fixed to the middle part of the long axis 1; the safety rope hanging ring 48 and the safety rope lifting ring 49 are respectively located on the front and rear sides of the long axis 1.

[0046] The safety rope includes two short ropes with a length of 50-60 cm, each of which is passed through a safety rope hanging ring 48 and a safety rope hanging ring 49 in turn and is respectively connected to two hanging points of the safety belt waist on the human body; when the staff walks normally, active braking is achieved by manually pulling the wrench 47 to drive the second clamping component 41; when the staff loses their footing and falls, the safety rope is tightened by the body's own gravity and then the wrench 47 is pulled to achieve passive braking.

[0047] Specifically, the rod body of the push rod 45 slides in the limit groove 11 on the upper surface of the long shaft 1; one end of the push rod 45 is connected to the wrench 47 through the connecting rod 46, and the other end of the push rod 45 is connected to the second clamping component 41; the push rod 45 and the connecting rod 46 are connected by a rotating shaft and an elongated circular hole. The second clamping component 41 is L-shaped, and the top of the second clamping component 41 is rotatably connected to one end of the push rod 45 through the cooperation of the rotating shaft and the elongated circular hole, and the middle part of the second clamping component 41 is rotatably connected to the bottom of the bracket 42 through the rotating shaft, and the top of the bracket 42 is fixed to the bottom of the long shaft 1 by bolts.

[0048] The second holding part 41 is L-shaped, the top of the second holding part 41 is rotatably connected to one end of the push rod 45 through the cooperation of the rotating shaft and the long round hole, the middle of the second holding part 41 is rotatably connected to the bottom of the bracket 42 through the rotating shaft, and the top of the bracket 42 is fixed to the bottom of the long shaft 1 through bolts. The bottom of the second holding part 41 is installed with a pressing plate 43 and a brake shoe 44 through bolts.

[0049] When the staff is moving forward on a line with a slope (e.g., downhill), they can achieve active braking by tightening the wrench 47, which can ensure that the staff can move forward safely on the sloped wire. Specifically, the wrench 47 drives the push rod 45 to slide toward the end of the long axis 1 through the connecting rod 46, and the second clamping component 41 connected to the other end of the push rod 45 rotates, and the bottom brake shoe 44 of the second clamping component 41 clamps the transmission wire, achieving active braking and ensuring the braking effect.

[0050] When a person slips and falls, the two safety ropes that pass through the safety rope hanging ring 48 and the safety rope hanging ring 49 in sequence are tightened as the person falls, and then the wrench 47 is pulled to achieve passive braking. Passive braking can assist the person who slips and falls to achieve on-site braking, avoiding secondary injuries caused by the person sliding along the slope of the line and colliding with the tower when the person slips and falls.

[0051] In addition, the present invention adopts a five-point fixed connection mode for the first time, which improves the safety performance and can realize the self-rescue on the spot after the staff slips and falls. Specifically, the safety rope includes two short ropes with a length of 50-60cm and a long rope with a length of 5-8m, wherein the two short ropes are connected to the two sides of the five-point safety belt of the staff after bypassing the safety rope hanging ring 48 and the safety rope hanging ring 49 in turn, and the long rope embraces the whole group of phase conductors (4 sub-conductors are one phase). Since the two short ropes are connected to the two sides of the human waist after bypassing the safety rope hanging ring 48 and the safety rope hanging ring 49 in turn, the double brake assembly quickly holds the transmission wire and the climbing wheel after the staff slips and falls, and the multi-split transmission line routing operation auxiliary device stops moving forward. Since the length of the short rope is almost equal to the single arm extension distance of an adult, the staff can hold the transmission wire with both hands, and push up with both feet to return to the safe operation position again, completing the self-rescue on the spot.

[0052] In a preferred embodiment, the end of the long shaft 1 is equipped with a self-locking tool hook with a hoop, which can be used to hang a backpack with tools, reduce the weight of the staff, save physical energy consumption, and facilitate the removal of tools. The self-locking tool hook with a hoop can be a commercially available product or can be prepared by yourself.

[0053] In other preferred embodiments, an electronic detection device bracket with a clamp is movably installed on the long axis 1 (a commercially available product may be used), such as a bracket for installing a tablet computer and a bracket for other electronic detection devices, which can be used to install some electronic equipment, such as a laser rangefinder, an odometer, a micro-weather station, a camera, a mobile terminal, etc., which can automatically collect operation information and connect the situation at the operation site with the unified video platform of the State Grid, breaking down spatial barriers. The sharing of high-altitude perspectives makes operation monitoring more intuitive and efficient, opens up a new mode of smart management, and improves the intelligence, efficiency and convenience of ultra-high voltage and ultra-high voltage transmission line routing operations.
