　　As an important supporting facility for cable laying in power, communication and other systems, the daily maintenance of cable trays directly affects the safety, stability and service life of cable operation. I will provide you with reference for the daily maintenance work after installing cable trays, including inspection, cleaning, protection, recording, and other aspects

　　一、定期巡檢與外觀檢查

　　1、 Regular inspection and visual inspection

　　定期巡檢是能否及時發現問題的關鍵所在，建議根據電纜橋架的使用環境制定巡檢周期，一般情況下每月少一次，惡劣環境下需縮短每周一次。檢查涵蓋的內容如下：

　　Regular inspections are the key to discovering problems in a timely manner. It is recommended to develop inspection cycles based on the usage environment of cable trays, generally at least once a month, and in harsh environments, it should be shortened to once a week. The inspection covers the following contents:

　　結構完整性檢查：

　　Structural integrity check:

　　1、支架與連接件——檢查橋架支架是否松動、變形或銹蝕，連接件（螺栓、螺母、卡扣等）是否齊全、緊固，有無缺失或脫落情況。若發現松動需及時用扳手擰緊；對于銹蝕嚴重的連接件，應及時更換為防腐性能更強的配件。

　　1. Bracket and connecting components - Check whether the bridge bracket is loose, deformed, or corroded, whether the connecting components (bolts, nuts, buckles, etc.) are complete, tightened, and whether there are any missing or detached situations. If looseness is found, it should be tightened with a wrench in a timely manner; For severely corroded connectors, they should be replaced with accessories with stronger anti-corrosion performance in a timely manner.

　　2、橋架本體——觀察橋架是否存在變形、凹陷、裂縫等物理損傷，特別是在跨越通道、重物可能碰撞的區域，需檢查是否有外力導致的結構損壞。

　　2. Bridge body - observe whether the bridge has physical damage such as deformation, indentation, cracks, etc., especially in areas where crossing channels or heavy objects may collide. It is necessary to focus on checking whether there is structural damage caused by external forces.

　　3、蓋板與隔板——檢查蓋板是否蓋嚴、固定牢固，避免灰塵、雜物進入或小動物鉆入；對于有防火、分隔要求的橋架，需檢查隔板是否完好、無位移或破損。

　　3. Cover plate and partition - check whether the cover plate is tightly closed, firmly fixed, and prevent dust, debris, or small animals from entering; For cable trays with fire prevention and separation requirements, it is necessary to check whether the partitions are intact, without displacement or damage.

　　表面狀況檢查：

　　Surface condition inspection:

　　1、銹蝕情況——查看橋架表面涂層（如鍍鋅層、噴漆層等）是否脫落、鼓包，金屬表面有無銹蝕斑點。在潮濕、多塵或腐蝕性環境中，需檢查銹蝕程度，若涂層破損應及時修補。

　　1. Corrosion condition - Check whether the surface coating of the bridge (such as galvanized layer, spray paint layer, etc.) has peeled off or bulged, and whether there are rust spots on the metal surface. In humid, dusty, or corrosive environments, it is important to focus on checking the degree of corrosion. If the coating is damaged, it should be repaired in a timely manner.

　　2、積污與異物——檢查橋架內部及表面是否堆積灰塵、油污、雜物（如紙張、塑料、金屬碎屑等），若存在應及時清理，避免積污過多影響散熱或引發火災隱患。

　　2. Accumulation of dirt and foreign objects - Check whether dust, oil stains, and debris (such as paper, plastic, metal shavings, etc.) have accumulated inside and on the surface of the bridge. If there are any, they should be cleaned up in a timely manner to avoid excessive accumulation of dirt affecting heat dissipation or causing fire hazards.

　　二、功能性能維護

　　2、 Functional performance maintenance

　　散熱性能維護 ：

　　Maintenance of heat dissipation performance:

　　對于敷設動力電纜、高功率電纜的橋架，需檢查周圍是否存在遮擋物（如板材、布料等），確保橋架通風良好，散熱順暢。 高溫環境下，可定期用紅外測溫儀檢測橋架表面及電纜溫度，若溫度異常升高（超過電纜允許工作溫度），需排查原因（如電纜過載、通風不良等）并及時處理。

　　For cable trays used for laying power cables and high-power cables, it is necessary to check for any obstructions (such as boards, fabrics, etc.) around the tray to ensure good ventilation and smooth heat dissipation. In high temperature environments, infrared thermometers can be used regularly to detect the surface temperature of cable trays and cables. If the temperature rises abnormally (exceeding the allowable working temperature of cables), the cause should be investigated (such as cable overload, poor ventilation, etc.) and dealt with in a timely manner.

　　防火與防護性能維護：

　　Fire prevention and protection performance maintenance:

　　1、 防火橋架——檢查防火涂層是否完好，有無開裂、脫落現象；防火封堵材料（如防火泥、防火包）是否完整，無松動或缺失，確保火災時能有效阻隔火勢蔓延。

　　1. Fireproof bridge - check whether the fireproof coating is intact, whether there are cracks or peeling phenomena; Whether the fireproof sealing materials (such as fireproof mud and fireproof bags) are complete, without looseness or missing, ensuring that they can effectively block the spread of fire in case of fire.

　　2、防鼠防蟲——在戶外、地下室等易受小動物侵擾的區域，檢查橋架入口、縫隙處是否安裝防鼠網、防蟲裝置，若裝置損壞應及時更換，避免小動物啃咬電纜。

　　2. Rat and insect prevention - In outdoor areas, basements, and other areas that are susceptible to small animal infestation, check whether rat nets and insect prevention devices are installed at the entrance and gaps of the bridge. If the devices are damaged, they should be replaced in a timely manner to avoid small animals biting the cables.

　　電纜敷設狀態檢查：

　　Cable laying status inspection:

　　檢查橋架內電纜是否排列整齊，有無過度彎曲、擠壓、拖拽現象，避免電纜絕緣層受損。 查看電纜標識是否清晰完整，若標識模糊或脫落，需及時補做，方便后續檢修識別。 對于有伸縮要求的橋架（如跨建筑物沉降縫、溫度伸縮縫處），檢查伸縮節是否靈活，有無卡滯現象，確保橋架能隨環境變化自由伸縮，避免拉扯電纜。

　　Check whether the cables in the cable tray are arranged neatly, whether there is excessive bending, squeezing, or dragging, and avoid damaging the insulation layer of the cables. Check if the cable markings are clear and complete. If the markings are blurry or detached, they should be promptly repaired to facilitate subsequent maintenance and identification. For cable trays with expansion requirements (such as cross building settlement joints and temperature expansion joints), check whether the expansion joints are flexible and whether there is any jamming phenomenon, to ensure that the cable tray can freely expand and contract with environmental changes, and avoid pulling and pulling the cables.

　　三、環境適應性維護

　　3、 Environmental adaptability maintenance

　　根據環境的不同進行針對性的維護

　　Targeted maintenance based on different environments

　　1、潮濕 / 多塵環境——增加巡檢頻率，定期清理橋架表面及內部積塵、凝水，對金屬部件進行防腐處理（如涂刷防銹漆、涂抹潤滑脂）；檢查橋架接地是否良好，避免電化學腐蝕。

　　1. Damp/dusty environment - increase inspection frequency, regularly clean the surface and interior of the bridge frame of dust and condensation, and carry out anti-corrosion treatment on metal components (such as painting with anti rust paint and applying lubricating grease); Check if the bridge grounding is good to avoid electrochemical corrosion.

　　2、腐蝕性環境（如化工車間、海邊）——選用耐腐蝕材質橋架（如玻璃鋼橋架、鋁合金橋架），定期檢查表面防腐層完好性，若發現腐蝕點應及時打磨并涂刷專用防腐涂料；避免橋架與腐蝕性液體、氣體直接接觸。

　　2. Corrosive environments (such as chemical workshops, beaches) - Choose corrosion-resistant material bridge frames (such as fiberglass bridge frames, aluminum alloy bridge frames), regularly check the integrity of the surface anti-corrosion layer, and if corrosion points are found, polish and apply special anti-corrosion coatings in a timely manner; Avoid direct contact between the bridge and corrosive liquids or gases.

　　3、戶外環境——檢查橋架是否有積水現象（特別是槽式橋架），若存在排水不暢需疏通排水孔；冬季需清理橋架上的積雪、結冰，避免積雪過重導致橋架變形。

　　3. Outdoor environment - check if there is water accumulation on the bridge frame (especially the trough bridge frame), and if there is poor drainage, clear the drainage holes; In winter, it is necessary to clean the snow and ice on the bridge to avoid deformation caused by excessive snow accumulation.

　　4、接地系統維護——檢查橋架接地裝置是否連接牢固，接地電阻是否符合規范要求（一般≤4Ω），可定期用接地電阻測試儀進行檢測。 若橋架與接地干線連接點出現松動、銹蝕，需及時處理，確保接地可靠，防止靜電積累或漏電引發事故。

　　4. Grounding system maintenance - check whether the bridge grounding device is firmly connected and whether the grounding resistance meets the specification requirements (generally ≤ 4 Ω), and regularly use a grounding resistance tester for testing. If the connection point between the bridge and the grounding main line becomes loose or corroded, it should be dealt with in a timely manner to ensure reliable grounding and prevent static electricity accumulation or leakage from causing safety accidents.

　　四、問題處理與記錄

　　4、 Problem Handling and Recording

　　1、故障與隱患處理——發現橋架松動、變形、銹蝕等輕微問題時，應及時修復；對于嚴重損壞（如結構斷裂、大面積銹蝕無法修復）的橋架，需制定更換計劃，避免發生事故。 若巡檢中發現電纜破損、發熱等與橋架相關的問題，需協同電氣人員共同處理，明確責任并及時整改。

　　1. Troubleshooting and Hidden Danger Handling - When minor issues such as loose, deformed, or corroded bridge frames are discovered, they should be promptly repaired; For bridge frames that are severely damaged (such as structural fractures or extensive rusting that cannot be repaired), a replacement plan should be developed to avoid safety accidents. If cable damage, heating, or other issues related to cable trays are found during inspections, it is necessary to collaborate with electrical professionals to jointly handle them, clarify responsibilities, and promptly rectify them.

　　2、維護記錄與檔案管理——建立電纜橋架維護臺賬，記錄每次巡檢時間、檢查內容、發現的問題、處理措施及處理結果。 存檔橋架的設計圖紙、安裝資料、產品合格證等文件，方便后續維護時查閱參數（如橋架規格、承重能力、防腐等級等）。 根據維護記錄分析橋架運行狀態，總結易出現問題的部位和原因，優化維護周期和措施。

　　2. Maintain records and archive management - Establish a cable tray maintenance ledger, recording the inspection time, inspection content, problems found, handling measures, and results of each inspection. Archive the design drawings, installation materials, product certification and other documents of the cable tray for easy reference of parameters (such as cable tray specifications, load-bearing capacity, anti-corrosion level, etc.) during subsequent maintenance. Analyze the operation status of the bridge frame based on maintenance records, summarize the parts and reasons that are prone to problems, optimize maintenance cycles and measures.

　　五、維護注意事項

　　5、 Maintenance safety precautions

　　進行維護作業前，需確認作業區域是否停電（涉及電纜帶電部分時），并設置警示標識，避免觸電事故。 高空作業（如橋架安裝在天花板、高空支架上）時，需使用合格的登高工具（如梯子、腳手架），系好帶，確保作業。 清理橋架內部時，避免使用金屬工具用力刮擦，防止損壞電纜絕緣層；使用清潔劑時，選擇不腐蝕橋架材質和電纜絕緣的型清潔劑。

　　Before carrying out maintenance work, it is necessary to confirm whether the work area has a power outage (when involving live parts of cables), and set up safety warning signs to avoid electric shock accidents. When working at heights (such as installing cable trays on ceilings or high-altitude supports), qualified climbing tools (such as ladders and scaffolding) must be used, and safety belts must be fastened to ensure the safety of the operation. When cleaning the interior of the cable tray, avoid using metal tools to scrape forcefully to prevent damage to the cable insulation layer; When using cleaning agents, choose environmentally friendly cleaning agents that do not corrode bridge materials and cable insulation.

　　通過以上的日常維護工作，可有效保障電纜橋架的結構穩定和功能正常，延長其使用壽命，同時為電纜系統的運行提供可靠支撐。在維護過程中，需結合實際使用環境和橋架類型，制定個性化的維護方案，做到預防為主、及時處理。

　　Through the above daily maintenance work, the structural stability and normal function of the cable tray can be effectively guaranteed, extending its service life, and providing reliable support for the safe operation of the cable system. During the maintenance process, it is necessary to develop personalized maintenance plans based on the actual usage environment and bridge type, with a focus on prevention and timely handling.
