停车场电缆桥架的日常维护主要包括以下几个方面：

　　The daily maintenance of cable trays in parking lots mainly includes the following aspects:

　　1.定期检查结构完整性

　　1. Regularly check the structural integrity

　　· 检查桥架是否有变形、扭曲、断裂或破损的情况，尤其注意连接部位、弯头和支吊架处，发现问题及时修复或更换。

　　·Check whether the bridge is deformed, twisted, broken or damaged, especially paying attention to the connection parts, bends and support hangers. If any problems are found, repair or replace them in a timely manner.

　　· 检查桥架的连接件、螺栓、螺母等固定部件是否松动或生锈，及时进行紧固或更换，确保桥架的稳定性。

　　·Check whether the connecting parts, bolts, nuts and other fixed components of the bridge are loose or rusted, and tighten or replace them in a timely manner to ensure the stability of the bridge.

　　2.保持清洁与通风

　　2. Maintain cleanliness and ventilation

　　· 定期清理桥架表面的灰尘、油污、杂物和积水，可使用软布、吸尘器或压缩空气进行清理，避免灰尘和杂物堆积影响散热和绝缘性能。

　　·Regularly clean the surface of the bridge frame of dust, oil stains, debris, and accumulated water. Soft cloth, vacuum cleaner, or compressed air can be used for cleaning to avoid the accumulation of dust and debris affecting heat dissipation and insulation performance.

　　· 保持桥架周围环境通风良好，确保电缆有足够的散热空间，避免因散热不良导致电缆过热。

　　·Maintain good ventilation around the cable tray and ensure sufficient heat dissipation space for the cables to avoid overheating caused by poor heat dissipation.

　　3.防腐处理与防护

　　3. Anti corrosion treatment and protection

　　· 检查桥架的防腐涂层（如喷塑、镀锌层等）是否完好，如有脱落、起皮或生锈现象，应及时补涂防腐漆或采取其他防腐措施。

　　·Check whether the anti-corrosion coating of the bridge frame (such as spray coating, galvanized layer, etc.) is intact. If there is any peeling, peeling or rusting phenomenon, timely apply anti-corrosion paint or take other anti-corrosion measures.

　　· 在潮湿、腐蚀性环境或户外的桥架，需加强防腐措施，必要时可增加防护罩或定期进行防锈处理。

　　·In damp, corrosive environments or outdoor cable trays, anti-corrosion measures need to be strengthened, and if necessary, protective covers can be added or regular rust prevention treatment can be carried out.

　　4.接地系统维护

　　4. Maintenance of grounding system

　　· 定期检测桥架的接地电阻，确保接地良好，接地电阻值符合设计要求，一般不应大于4欧姆。

　　·Regularly check the grounding resistance of the bridge frame to ensure good grounding and that the grounding resistance value meets the design requirements, generally not exceeding 4 ohms.

　　· 检查桥架的接地连接是否牢固，接地线是否有破损、断裂或接触不良的情况，发现问题及时修复。

　　·Check whether the grounding connection of the bridge is firm, whether the grounding wire is damaged, broken or has poor contact, and promptly repair any problems found.

　　5.电缆状态检查

　　5. Cable status inspection

　　· 查看电缆是否有外皮破损、老化、裂纹、变色或过度弯曲的现象，发现问题及时更换或修复电缆。

　　·Check if there is any damage, aging, cracking, discoloration or excessive bending of the outer skin of the cable, and replace or repair the cable in a timely manner if any problems are found.

　　· 检查电缆的固定情况，确保电缆在桥架内固定牢固，避免电缆松动、脱落或相互摩擦，同时保持电缆敷设整齐，避免过度挤压。

　　·Check the fixing condition of the cables to ensure that they are firmly fixed inside the cable tray, avoiding cable looseness, detachment, or mutual friction. At the same time, keep the cable laying neat and avoid excessive compression.

　　6.特殊环境关注

　　6. Special environmental concerns

　　· 若停车场环境潮湿，需注意桥架接头处的密封性，防止水汽渗入，必要时可使用防水胶带或密封胶进行密封处理。

　　·If the parking lot environment is humid, attention should be paid to the sealing of the bridge joints to prevent water vapor from seeping in. If necessary, waterproof tape or sealant can be used for sealing treatment.

　　· 在高温环境下，观察桥架的散热状况，确保电缆不会因过热而影响性能，可采取增加通风设备或调整电缆布局等措施。

　　·In high temperature environments, observe the heat dissipation of the cable tray to ensure that the performance of the cable is not affected by overheating. Measures such as adding ventilation equipment or adjusting cable layout can be taken.

　　7.记录与档案管理

　　7. Record and archive management

　　· 建立桥架维护记录档案，详细记录每次维护的时间、内容、发现的问题及处理措施等，以便跟踪桥架的运行状况和维护历史，为后续维护提供参考。通过以上日常维护措施，可有效延长停车场电缆桥架的使用寿命，确保电缆系统的稳定运行。

　　·Establish a bridge maintenance record file, detailing the time, content, problems discovered, and solutions for each maintenance, in order to track the operation status and maintenance history of the bridge and provide reference for subsequent maintenance. Through the above daily maintenance measures, the service life of the parking lot cable tray can be effectively extended, ensuring the safe and stable operation of the cable system.
