TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric power appliances, especially relates to a cable trench cover plate quick lifting device. BACKGROUND

[0002] The cable trench cover plate refers to a special plate material used for covering the cable trench, and is usually used in the electric power, communication and other industries. The cable trench cover plate is widely used in the underground cable trench of the urban electric power, communication and other industries. They not only protect the safe operation of the underground cable, can effectively prevent heavy objects or other external objects from being pressed thereon, so as to protect the cable from being damaged, but also maintain the safety and tidiness of the surrounding environment.
