Technical Field

[0001] This utility model belongs to the field of power transmission and transformation engineering technology, specifically, it relates to a line adjustment and fixing device for power transmission and transformation engineering. Background Technology

[0002] In power transmission and transformation projects, cables need to be fixed and adjusted to ensure the stability and safety of the lines. Existing cable fixing devices mainly suffer from problems such as inconvenient installation, poor adjustment flexibility, and insufficient cable protection. For example, commonly used cable fixing clips use a rigid clamping structure, which not only easily damages the cable surface but also cannot adapt to cables of different diameters. Other devices have complex structures; for instance, CN120237559A discloses a cable fixing device for power engineering, whose complex structure makes cable disassembly and adjustment difficult, increasing maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to provide a line adjustment and fixing device for power transmission and transformation projects to solve the technical problems existing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A line adjustment and fixing device for power transmission and transformation projects includes two parallel and symmetrically arranged frame plates, multiple crossbeams arranged between the two frame plates, and a movable clamping mechanism for securing cables. The movable clamping mechanism includes a top plate, wing plates symmetrically arranged on both sides of the top plate, and the lower end of the wing plates is detachably connected to the crossbeams. The top plate and the wing plates together form a space for limiting the cable. Fastening bolts are provided on the top plate, the lower end of the fastening bolts passing through the top plate and the end of the bolts being provided with an upper arc-shaped abutment. Horizontal arc-shaped base plates are symmetrically arranged on the inner sides of the two wing plates and connected to them by springs.

[0022] To enable those skilled in the art to have a clearer understanding of this utility model, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described below are merely illustrative of this utility model and facilitate understanding. The technical solutions provided by this utility model are not limited to those provided in the following embodiments, nor should they limit the scope of protection of this utility model.

[0023] Example like Figures 1-5 As shown, this embodiment provides a line adjustment and fixing device for power transmission and transformation projects, including two parallel and symmetrically arranged frame plates 1. Each frame plate 1 has multiple spaced through holes 11 along its length for fixing the entire device to other supporting structures using bolts or other fasteners. The length of the frame plates 1 is not particularly limited and can be selected according to the actual application scenario. Multiple crossbeams 2 are arranged between the two frame plates 1, with adjacent crossbeams 2 spaced apart to provide multiple cable fixing points.

[0024] In this embodiment, the cross frame 2 includes two parallel and symmetrically arranged single frame bodies 21. The two ends of the single frame body 21 are fixedly connected to the two frame plates 1 respectively. The connection method can be conventional fixed connection methods such as welding and bolt fastening. Preferably, the single frame body 21 is U-shaped, the open ends of the two single frame bodies 21 are arranged opposite each other, and a gap 22 is reserved between them.

[0025] The movable clamping mechanism 4 works in conjunction with the crossbeam 2 to secure the cable 3. In this embodiment, the movable clamping mechanism 4 includes a top plate 41 and wing plates 42 symmetrically arranged on both sides of the top plate 41. The upper ends of the wing plates 42 are connected to the ends of the top plate 41 via inclined connecting plates 49. The inclined connecting plates 49 are inclined inward, so that the distance between the two wing plates 42 is greater than the length of the top plate 41. The top plate 41 and the wing plates 42 enclose an approximately U-shaped space to accommodate the cable 3.

[0026] In this embodiment, the lower end of the wing plate 42 is detachably connected to the cross frame 2. Specifically, the lower end of the wing plate 42 is configured as an anchor hook 47, with notches 48 symmetrically arranged on both sides of the anchor hook 47. During assembly, the anchor hook 47 is tilted relative to the cross frame 2, so that the hook on one side engages with the single frame 21 on that side. Then, the anchor hook 47 is rotated so that the hook on the other side engages with the single frame 21 on that side. This allows the anchor hook 47 to engage with both single frames 21 of the cross frame 2, with the upper end of the single frame 21 embedded in the notches 48, thereby achieving a reliable connection between the movable locking mechanism 4 and the cross frame 2. This connection method facilitates quick installation and disassembly to accommodate cable position adjustments. In this embodiment, the top plate 41, wing plate 42, anchor hook 47, and oblique connecting plate 49 are preferably integral structures, formed by casting or stamping to improve overall strength and durability.

[0027] In this embodiment, a fastening bolt 43 is provided on the top plate 41. The lower end of the fastening bolt 43 passes through the top plate 41 and its end is fixed with an upper arc-shaped abutment plate 44. Horizontal arc-shaped base plates 45 are symmetrically arranged on the inner side of the two wing plates 42. The horizontal arc-shaped base plates 45 are connected to the wing plates 42 by springs 46. Preferably, two spaced springs 46 are provided on the inner side of each wing plate 42 to ensure the stability of the horizontal arc-shaped base plates 45 and provide elastic support.

[0028] When cable 3 is placed on the crossbar 2, tighten the fastening bolt 43, and the upper arc-shaped abutment plate 44 moves downward to press the upper part of cable 3; at the same time, the spring 46 enables the horizontal arc-shaped base plates 45 on both sides of the wing plate to adapt to the size changes of the cable, providing buffer and uniform clamping force, so that the horizontal arc-shaped base plates 45 on both sides abut against the left and right sides of cable 3, while avoiding damage to the surface of the cable.

[0029] In practical applications, the entire device is first fixed to the support structure of the power transmission and transformation project through the through holes 11 on the frame plate 1. After the cable 3 is placed, according to the cable layout requirements, the movable clamping mechanism 4 is clamped to the appropriate position of the cross frame 2 through the anchor hook 47, so that the movable clamping mechanism 4 covers the cable 3. The horizontal arc-shaped bottom plates 45 on both sides of the wing plate hold the two sides of the cable 3. Then, the fastening bolts 43 are adjusted so that the upper arc-shaped abutment plate 44 is lowered and abuts against the upper part of the cable 3, thus completing the fixation.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
