Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, specifically relating to a protective device for climbing power transmission towers. Background Technology

[0002] High-altitude operations, as a crucial aspect of ensuring the normal power supply of the power system, have long been a key focus of power supply companies' operation and maintenance. Currently, the safety protection measures for power grid unit transmission line maintenance personnel climbing power towers mainly rely on carrying related tools such as double hooks, double safety ropes, and safety rings. This not only increases the load on the workers and the difficulty of the operation, but also means that when the first worker climbs the tower, they are almost entirely dependent on their own safety measures to complete the ascent. Given the influence of various factors such as the natural environment, the condition of the tower, and the worker's own physical condition, there is a high possibility of accidental falls, making the climbing extremely risky.

[0003] With the development of drone technology, research has emerged on using drones to carry safety ropes and their fixing devices to climb towers. For example, CN2022112178758 discloses a fall protection device and its mounting device. However, the relevant device requires the drone to take off with the device and safety rope. For power towers with a height of more than 50 meters, the total weight of the safety rope and device exceeds 8 kg. In practical applications, the requirements for the take-off load and power supply of the drone are high, resulting in high usage costs. Utility Model Content

[0004] The purpose of this invention is to provide a protective device for climbing power transmission towers. An anchor fixing device and a traction rope are hoisted to the top of the tower using a drone. The traction rope and safety rope are connected by a safety ball.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] like Figure 1 As shown, the present invention provides a climbing protection device for power transmission towers, comprising an outer support 1, an inner support 2, a rotating pressure plate 3, a rope clamping mechanism 4, a hinge baffle mechanism 5, a protective shell 6, a safety ball 7, a traction rope 8, a safety rope 9, and a hanging ring 10.

[0033] See Figure 2 The outer shell 1 is a symmetrical gate-shaped structure, consisting of a connected top plate 11, a left side shell 12, and a right side shell 13. The top plate 11, left side shell 12, and right side shell 13 have bends on their front and rear sides. The left side shell 12 and right side shell 13 each have four symmetrical sliding grooves 14 to limit the direction and distance of relative sliding between the outer shell 1 and the inner support 2. The bottom of the right side shell 13 has a rectangular hole 15 for the passage of the rotating pressure plate 3. At the connection between the top plate 11 and the left side shell 12 and right side shell 13, there is a symmetrical L-shaped raised structure A 16 with a connecting hole A 17 for connecting the outer shell 1 to the lifting ring 10. The bottom of the right side shell 13 has a raised structure B 18 with a connecting hole B 19 for installing the rope clamping mechanism 4 and the protective shell 6.

[0034] See Figure 3 The inner support 2 is a rectangular metal frame structure in top view. Its thickness is the same as that of the outer shell 1, and its width is slightly smaller than that of the outer shell 1 to ensure smooth installation inside the outer shell 1. The left side plate 21 and the right side plate 22 of the inner support each have four connecting holes C 23 for connecting the inner support 2 to the outer shell 1. The right side plate 22 has a rectangular hole 24 in the middle, the size of which allows the short side plate 33 of the rotating pressure plate 3 to pass through smoothly. The front plate 25 and the rear plate 26 of the inner support are lower than the height of the left side plate 21 and the right side plate 22, forming a groove at the bottom of the inner support 2. At the corner of the top side of the groove, there is a pair of equal and symmetrical arc-shaped protrusions 27, with a pair of equal and symmetrical shaft holes A 28 on them for connecting the inner support 2 to the rotating pressure plate 3.

[0035] See Figure 4The rotating pressure plate 3 is an integrated structure composed of a shaft hole B 31, a bent pressure plate 32, a short-side pressure plate 33, a long-side pressure plate 34, and a connecting plate 35. The thickness of the rotating pressure plate 3 is slightly less than the thickness of the inner support 2, and its dimensions ensure smooth rotation into the inner support 2. The shaft hole B 31 is used for connection with the inner support 2. The front end of the bent pressure plate 32 is bent and has a raised structure 36 to increase the weight of the rotating pressure plate, achieving gravity-based rotation and self-locking. The length of the short-side pressure plate 33 is slightly less than the height of the rectangular hole 24 in the inner support, and its dimensions ensure smooth passage through the rectangular hole 24 in the inner support. The angle between the short-side pressure plate 33 and the long-side pressure plate 34 is 90 degrees, and the angle between the bent pressure plate 32 and the long-side pressure plate 34 is approximately 30 degrees. The connecting plate 35 is located between the short-side pressure plate 33 and the long-side pressure plate 34 to reinforce the mechanical properties of the overall structure.

[0036] See Figure 5 The rope clamping mechanism 4 has an L-shaped structure, consisting of a long plate 41 and a short plate 42. The top of the long plate 41 has a rope clamping mechanism through hole A 43, which is used to connect with the connecting hole B 19 at the bottom of the outer casing 1. The bottom of the short plate 42 has a rope clamping mechanism through hole B44, the diameter of which is larger than the diameter of the safety ball 7, ensuring that the safety ball 7 can pass through smoothly.

[0037] See Figure 6 The hinge baffle mechanism 5 consists of a U-shaped baffle 51 and a hinge 52. The outer contour dimension of the U-shaped baffle 51 is slightly smaller than the cross-sectional dimension of the short plate 42 of the rope clamping mechanism 4. One side of the hinge 52 is installed on one side of the bottom short plate 42 of the rope clamping mechanism 4, and the other side is installed on one side of the top of the U-shaped baffle 51. When the safety ball 7 passes from bottom to top through the rope clamping mechanism 4 under the drive of the traction rope 8, the hinge 52 ensures that the safety ball 7 smoothly lifts the U-shaped baffle 51 and passes through.

[0038] See Figure 7 The protective shell 6 consists of a top plate 61, a front plate 62, a rear plate 63, and side plates 64. The top plate 61 is square, while the front, rear, and side plates 64 are rectangular. The lower right corner of the front plate 62 has a rectangular hole A 65, leaving space for the installation of the hinge 52. The upper right corner of the rear plate 63 has a rectangular hole B 66 for the passage of the safety ball 7, the traction rope 8, and the safety rope 9. The top of the front and rear plates 62 and 63 have a pair of shaft holes B 67 for shaft connection with the connecting hole B19 of the outer shell 1.

[0039] See Figure 8 The safety ball 7 has a spherical structure. The safety ball has a countersunk threaded hole 71 in the horizontal direction for installing the double-rope connecting bolt 72. The safety ball has a through keyway hole 73 in the vertical direction.

[0040] The working principle of this utility model is as follows:

[0041] See Figure 1 When deploying the climbing protection device, the traction rope 8 is passed through the through hole B 44 on the short plate of the rope clamping mechanism and the rectangular hole B 66 on the rear plate of the protective shell. The drone carries the climbing protection device and traction rope 8 to the top of the tower via the lifting ring. As the drone rises, the middle position of the traction rope 8 is raised, and both ends of the traction rope 8 hang down to the ground. The operator controls the drone so that the angle iron at the edge of the tower is positioned between the left side plate 12 and the right side plate 13 of the climbing protection device shell, and slowly lowers the drone's altitude.

[0042] The drone lowers the climbing protection device. When the curved pressure plate 32 in the rotating pressure plate 3 first contacts the top of the angle iron, as the drone continues to descend, the curved pressure plate 32 encounters resistance from the angle iron, and the moving short side pressure plate 33 and the long side pressure plate 34 of the rotating pressure plate 3 begin to rotate. The short side pressure plate 33 passes sequentially through the rectangular hole 24 of the inner support and the rectangular hole 15 of the outer shell. The drone continues to descend, and when the proximal end of the curved pressure plate 32 rotates to near horizontal, the short side pressure plate 33 completely enters the interior of the inner support 2, and the long side pressure plate 34 rotates to contact the bottom surface of the angle iron and remains horizontal. The drone continues to descend, and the inner support 2 stops moving downward under the support of the angle iron. The outer shell 1 continues to descend under the constraint of the sliding groove 14. The top of the inner support 2 coincides with the lower surface of the top plate 11 of the outer shell, realizing the automatic locking of the climbing protection device with the angle iron at the top of the tower.

[0043] After the climbing protection device automatically locks, pass one end of the safety rope 9 through the lower half of the safety ball keyway 73 and fix it to the connecting bolt 72; pass one end of the traction rope 8 through the safety ball keyway.

However, as previously stated, it should be understood that the utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the utility model concept described herein through the foregoing teachings or the technology or knowledge in related fields.
