Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to an insulated ladder for power engineering. Background Technology

[0002] In the field of power engineering, working at height is a common part of the work process. Insulated ladders are widely used as important tools for working at height. Traditional insulated ladders have a relatively simple structure, usually consisting of only a basic ladder frame and steps. When in use, their unfolding and fixing methods often rely on relatively simple mechanical connection structures, such as simple hooks or bolts.

[0003] However, in actual use, this traditional fixing method has many drawbacks. On the one hand, the operation is cumbersome, requiring a lot of time and effort to adjust the unfolded width of the ladder and ensure its stability. In emergency operation scenarios such as power engineering repairs, every second of delay may lead to a longer power supply interruption time, affecting users' normal power use and causing economic losses. On the other hand, the fixing structure of traditional insulated ladders has limited stability. In complex power construction sites, such as strong winds, uneven ground, or large shaking caused by operators, the ladder is prone to loosening, displacement, or even tipping over, seriously threatening the lives of operators.

[0004] Therefore, we propose an insulated ladder for power engineering. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: an insulated ladder for power engineering includes a top plate 1, a right ladder 2 rotatably connected to the bottom of the top plate 1, a left ladder 3 rotatably connected to the bottom of the top plate 1, and a snap-fit ​​assembly 4 provided on the right ladder 2.

[0026] In one embodiment of this utility model, the snap-fit ​​assembly 4 includes a slide groove 41. A slide groove 41 is provided on the right ladder 2, and a spring groove 42 is provided on the slide groove 41. Multiple sets of spring grooves 42 are arranged linearly at equal intervals within the slide groove 41. A telescopic rod 43 is fixedly connected within the spring groove 42. A small spring 44 is sleeved on the outside of the telescopic rod 43, and a semi-circular block 45 is fixedly connected to the small spring 44. Multiple sets of telescopic rods 43, small springs 44, and semi-circular blocks 45 are arranged linearly at equal intervals within the slide groove 41. A slider 46 is slidably connected to the top plate 1, which causes the slider 46 to slide within the groove 41, thereby compressing the semicircular block 45, which in turn compresses the small spring 44, which in turn compresses the telescopic rod 43 in the spring groove 42, thereby adjusting the slider 46 and fixing the distance between the right ladder 2 and the left ladder 3. A telescopic column 47 is rotatably connected to the slider 46, and a hollow rod 48 is slidably connected to the telescopic column 47. When the workers need the ladders to work, the right ladder 2 and the left ladder 3 are pulled apart through the top plate 1, thereby causing the hollow rod 48 to slide within the telescopic column 47.

[0027] In one embodiment of this utility model, a fixing component 5 is provided on the hollow rod 48, a cylinder 51 is fixedly connected to the hollow rod 48, a sliding column 52 is slidably connected inside the cylinder 51, a fixing block 53 is fixedly connected to the sliding column 52, a small rod 54 is fixedly connected to the sliding column 52, an L-shaped groove 55 is opened on the cylinder 51, the small rod 54 is slidably connected in the L-shaped groove 55, a small groove 56 is opened on the telescopic column 47, a limiting groove 57 is opened on the small groove 56, a limiting block 58 is slidably connected to the limiting groove 57, two sets of limiting blocks 58 are provided, and the two sets of limiting blocks 58 are mirror images of the vertical center line of the circular block 59 in the front-back direction, and are mirror images of the left and right ends of the circular block 59. A circular block 59 is fixedly connected to the limiting block 58, and the lower part of the circular block 59 is fixedly... The ladder is fixedly connected to a short spring 510. Multiple sets of slots 56, limiting slots 57, limiting blocks 58, circular blocks 59, and short springs 510 are arranged linearly at equal intervals within the telescopic column 47. The short springs 510 are fixedly connected within the slots 56. By pressing the fixing block 53, the sliding column 52 slides within the cylinder 51, causing the small rod 54 to move within the L-shaped groove 55. The sliding column 52 then contacts the slot 56, compressing the circular block 59, which in turn compresses the short springs 510. This causes the limiting block 58 to slide within the limiting slot 57, thus performing a locking action and further securing the ladder.

[0028] Working principle: When workers need the ladder for work, the right ladder 2 and left ladder 3 are pulled apart by the top plate 1, which causes the hollow rod 48 to slide in the telescopic column 47, thereby causing the slider 46 to slide in the slide groove 41, thus compressing the semi-circular block 45, which in turn compresses the small spring 44, which in turn compresses the telescopic rod 43 in the spring groove 42, thereby adjusting the slider 46 and fixing the distance between the right ladder 2 and left ladder 3. Then, by pressing the fixing block 53, the sliding column 52 is moved in the cylinder 51, which causes the small rod 54 to move in the L-shaped groove 55, so that the sliding column 52 contacts the small groove 56, thereby compressing the circular block 59, which in turn compresses the short spring 510, thereby causing the limiting block 58 to slide in the limiting groove 57, thereby locking and further fixing the ladder.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
