Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission and transformation engineering, and particularly relates to a cable fixing rack for power transmission and transformation engineering. Background Art

[0002] In power transmission and transformation projects, cables are an important part connecting transmission and substations. They are responsible for transmitting high-voltage electricity from power stations to substations, and from substations to users' power points. The performance and reliability of cables are directly related to the stable operation and power supply quality of the entire power system.

[0003] Cable installation requires the support of cable clamps. Cable clamps are devices used to support and secure cables. In many cases, cables need to be installed high to prevent contact with people or other equipment, improving power transmission safety. This requires the use of cable clamps to elevate the cables.

[0004] Chinese patent CN213027338U discloses a cable fixing bracket. When using this bracket, the cable is first placed in the placement slot on the placement block, then the cable is pressed with a pressure block. Finally, the placement block and the pressure block are bolted together to secure the cable, preventing it from moving during installation. While this patented technology can solve the problem of cable movement, it still has the following technical drawbacks in actual use: because the placement slot on the placement block and the slot on the pressure block are of fixed size, this reduces the applicability of the cable fixing bracket.

[0005] Chinese patent CN216252007U discloses a wire and cable fixing bracket, which comprises a fixing cover, an inlay block, and an inlay slot. The inlay block on the left side of the fixing cover is arranged to be vertically inlaid and movable, and the inlay block and the inlay slot are arranged to be inlaid and movable. The inlay block is embedded in the inlay slot to improve the securement of the fixing cover. The inlay block is ejected from the inlay slot by pressing an opening and closing button to facilitate opening of the fixing cover. The fixing cover then covers and secures the wires and cables in the cable fixing slot, thereby improving the cable fixation of existing wire and cable fixing brackets and preventing them from falling off the bracket. However, the fixing cover does not provide any buffering capability for covering and securing the wires and cables in the cable fixing slot. During actual use, the cables inevitably sway, causing them to pull against the fixing portion. Without any buffering capability, the cables slowly slide toward one end, resulting in uneven tightness of the cables at both ends of the fixing portion, affecting their use and subsequent maintenance efficiency.

[0006] In addition, after the existing cable fixing frames used in some power transmission and transformation projects lift the cables, the contact area with the bottom of the cables is generally relatively fixed. As the cables shake due to environmental influences, the relatively narrow contact area is very likely to wear the bottom of the cables, which is quite inconvenient. Utility Model Content
