Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cover plate handling, in particular to an automatic cable trench cover plate handling device. BACKGROUND

[0002] The cable trench cover plate of a transformer substation is a plate-shaped structural member covering the cable trench in the transformer substation. Its main function is to protect the cable, ensure safety, and maintain a clean environment. The traditional cable trench cover plate of a transformer substation is made of reinforced concrete. The cover plate is large in size and heavy in weight. With the development of science and technology, composite cover plates have been used. They have the advantages of light weight, high strength, corrosion resistance, good insulation, and difficulty in being stolen. They are becoming more and more commonly used in modern transformer substations. When laying the cover plate, it is strictly sealed. Although it is not easy to be stolen, it is difficult to handle the cable trench cover plate during maintenance.

[0003] In the existing patent CN115285906A, a transformer substation cable trench cover plate lifting device and its use method are disclosed. The transformer substation cable trench cover plate lifting device is used for lifting and handling the cable trench cover plate. It includes a lever, the lower end of which is connected to an angle steel. The middle section of the lever is connected to a handling rod. The end of the handling rod is provided with a lifting piece. The angle between the handling rod and the lever is obtuse. The bottom of the lever is provided with a roller. The transformer substation cable trench cover plate lifting device and its use method use the principle of leverage in combination with an angle steel and a handling rod to effectively correspond to the small gap of the cable trench cover plate. It solves the problem that the work personnel have few points of application when lifting the cover plate, and there is a risk of injuring the work personnel due to unstable application. It greatly improves work efficiency.

[0004] In the above structure, the handling function of the cable trench cover plate can be realized. However, when laying, the cover plate is strictly sealed with the cable trench to prevent theft, and there is almost no gap. When picking up the cover plate, static friction occurs between the cover plate and the inner wall of the cable trench. When the first cover plate is lifted, a closed space is formed inside, and air cannot enter in time, resulting in the generation of instantaneous negative pressure, which causes the cover plate to be sucked and cannot be smoothly lifted. Generally, the work personnel need to use tools to repeatedly flip the cover plate to allow air to enter the edge to eliminate friction and negative pressure. This not only increases the labor intensity of the work personnel and improves the risk, but also easily damages the cover plate, reduces the service life of the cover plate, and greatly reduces the work efficiency.
