Description

Technical Field

[0001] This utility model relates to the technical field of cable tray support devices, specifically a span support device for cable trays used in thermal power plants. Background Technology

[0002] In the power system of a thermal power plant, cable trays bear the crucial task of laying and supporting a large number of cables. Some cable trays have large spans, making it difficult for them to effectively support the cables. Therefore, span support devices are needed to support the cable trays, reducing deformation, vibration, or sagging under their own weight, loads, or external environmental influences, thereby improving overall stability and reliability. The stability and reliability of these span support devices directly affect the safe operation of the cables and the normal production of the entire thermal power plant. Thermal power plants have complex environments, characterized by high temperatures, high vibration, and high dust levels.

[0003] Existing cable tray support devices used in thermal power plants mostly employ simple rigid bracket structures with fixed connection points. Under prolonged high-temperature environments, this structure is prone to thermal expansion and contraction deformation of the support components, leading to loosening of the support structure and subsequent cable tray sagging. This affects cable laying accuracy and operational safety. Furthermore, in high-vibration environments, fixed connection points are unable to absorb vibration energy, which is gradually transmitted to the cable tray, accelerating cable wear and aging, and potentially causing cable tray breakage and power outages. In addition, existing support devices have limited adjustment capabilities, making it inconvenient to adjust the height of some components according to usage requirements, resulting in poor flexibility and applicability. Therefore, there is an urgent need for a cable tray support device that can adapt to the harsh environment of thermal power plants and possesses good stability and adjustability.
