Description

Technical Field

[0001] This invention belongs to the technical field of high-voltage power tower maintenance equipment, specifically relating to a safety locking device for high-voltage power tower maintenance. Background Technology

[0002] With the rapid development of science and technology, electricity has been widely used in various industries. After years of catching up and surpassing, my country's power transmission technology has reached the international leading level, and the length of its transmission lines ranks first in the world. Due to my country's vast territory and the different regions where power production and consumption are concentrated, a large number of high-voltage transmission lines are needed to transport electricity, resulting in the construction of many high-voltage power towers. To ensure the normal transmission of electricity, power maintenance personnel often need to climb the towers for maintenance work. Currently, maintenance personnel need to continuously and alternately move the safety rope clamp upwards to ensure safety when climbing the towers. However, due to the limited reach of a person's arm, the safety rope clamp can only be hung slightly above the head each time, and the suspension height is far below the safety standard, posing a significant safety hazard. With the rapid development of drone technology, using drone technology to achieve pre-suspension of the safety clamp is a better solution. Therefore, it is necessary to design a safety locking device for high-voltage tower maintenance that can be used in conjunction with drones. Summary of the Invention

[0018] Embodiments of the present invention 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 the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0020] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0021] like Figure 1 As shown, a safety locking device for high-voltage tower maintenance according to the present invention includes a first U-shaped bracket 1, a hook 3 is provided on one outer side of the first U-shaped bracket 1, a locking tongue hole is provided on the other outer side of the first U-shaped bracket 1, a locking tongue 16 is provided in the locking tongue hole and a driving mechanism is provided on the upper side of the first U-shaped bracket 1, and the driving mechanism is in transmission cooperation with the locking tongue 16.

[0022] During operation, a drone is used to lift the entire device, ensuring that the first U-shaped bracket 1 is secured to the crossbeam 19 of the power tower. Then, the drive mechanism drives the locking tongue 16 to move inward and press it firmly against the crossbeam 19 to complete the locking and fixing. During disassembly, the drive mechanism drives the locking tongue 16 to move outward, away from the crossbeam 19 to complete the disassembly.

[0023] Combination Figures 2 to 4In a safety locking device for high-voltage tower maintenance according to the present invention, the driving mechanism includes a second U-shaped frame 11 disposed on the upper side of the first U-shaped frame 1. A slide rod 7 is inserted into the top of the second U-shaped frame 11. An iron block 9 is disposed at the upper end of the slide rod 7. A limit plate 10 is disposed at the lower end of the slide rod 7. A first rack 14 is disposed on the lower side of the limit plate 10. A spring 8 is sleeved on the slide rod 7. A rotating shaft 6 is rotatably disposed inside the second U-shaped frame 11. A first gear 12 and two second gears 13 are disposed on the rotating shaft 6. Each second gear 13 meshes with a second rack 5. A third U-shaped frame 15 is connected to the lower side of the two second racks 5. The third U-shaped frame 15 is connected to the locking tongue 16.

[0024] When high-voltage power towers need maintenance, the electromagnet at the bottom of the drone attracts the iron block 9 on the device. The drone is then raised to the maintenance height, and the lower end of the first U-shaped frame 1 is placed on the crossbeam 19 of the power tower. At this time, the electromagnet on the drone is released. Under the force of the spring 8 and the gravity of the sliding rod 7 and the first rack 14, the sliding rod 7 moves downward, pushing the first gear 12 to rotate. The rotating shaft 6 drives the two second gears 13 to rotate synchronously. The two second gears 13 drive the locking tongue 16 to move inward through the two second racks 5, locking the crossbeam 19. At this time, maintenance personnel can use the safety rope on the hook 3 to climb the power tower to carry out maintenance work. After the maintenance personnel complete the maintenance, the electromagnet is activated, attracting the iron block 9. The drone moves upward, causing the sliding rod 7 to move upward, and the locking tongue 16 gradually retracts, slowly releasing the crossbeam 19 until it is completely detached from the crossbeam 19. The drone can then remove the device for future use.

[0025] Combination Figure 5 In a safety locking device for high-voltage tower maintenance according to the present invention, guide pins 17 are provided on both sides of the tail of the locking tongue 16, and a pair of ear plates 4 are provided on the other outer side of the first U-shaped frame 1. A guide groove is provided in the middle of the ear plate 4, and the two guide pins 17 are respectively locked in the corresponding guide grooves. The two guide pins 17 are connected to both sides of the third U-shaped frame 15.

[0026] This design ensures that the locking tongue 16 moves back and forth along the set trajectory based on the two guide slots without deviating.

[0027] Combination Figure 5 In a safety locking device for high-voltage tower maintenance according to the present invention, a support plate 18 is provided inside the second U-shaped frame 11, the slide rod 7 is located above the support plate 18, and the first gear 12, the second gear 13, and the second rack 5 are all located below the support plate 18. A limiting groove is provided on the support plate 18, and the first rack 14 passes through the limiting groove to ensure that the first rack 14 will not deviate.

[0028] Combination Figure 5In a safety locking device for high-voltage tower maintenance according to the present invention, both sides of the lower end of the first U-shaped frame 1 are provided with outwardly curved arc-shaped guide plates 2, which facilitates the guidance and positioning of the first U-shaped frame 1 when it is placed on the crossbeam 1, and quickly completes the assembly.

[0029] Therefore, the safety locking device for high-voltage tower maintenance of the present invention can be transported to the crossbeam of the power tower by a drone, and the locking device composed of a spring and gear rack mechanism can lock the crossbeam to achieve the safety locking. The entire safety locking device ingeniously realizes the functions of locking and automatic release through mechanical structure, and has the advantages of simple and reliable structure and convenient operation.
