Description

Technical Field

[0001] The invention relates to the field of cable trench covers, and in particular to a cable trench cover, a cover moving device and a moving method thereof. Background Art

[0002] After the existing cable trench has completed the cable laying, it is usually necessary to customize multiple cover plates that are compatible with the cable trench and evenly lay them on the cable trench along the direction of the cable trench. This is mainly to make the ground flat, facilitate the movement of equipment and personnel, and protect the cables in the cable trench. After the cover plates are covered, if relevant personnel need to inspect or replace the cables in the cable trench, they generally need to open the cover plates before performing the corresponding operations.

[0003] At present, the devices on the market for moving and laying cable trench covers are mainly divided into two types: clamping type and suction cup type. The clamping type uses a gripper to clamp the side wall of the cover, and cooperates with a lifting device, a moving device, etc. to lift and move the cover. The suction cup type uses a vacuum suction cup to adsorb on the surface of the cover, and cooperates with a lifting device, a moving device, etc. to lift and move the cover.

[0004] The above two types of cover moving devices can well realize the operations of lifting, moving and laying the cover, but there are also some problems. For example, when the clamping type cover moving device clamps the cover for lifting and laying, the clamping claws need to clamp the side of the cover, and a gap needs to be reserved between the cover and the cable groove during lifting. The size of the gap is determined by the thickness of the clamping claws. First, it is not convenient to calculate the size of the cover, and it is easy to be affected by stones and other debris during clamping, which can easily affect the clamping strength and cause the cover to fall off, which poses certain hidden dangers. When the suction cup type cover moving device is in use, it has high requirements on the flatness of the cover surface. If there are slots, protrusions, etc. on the surface of the cover, the suction cup type cover moving device is difficult to play a role, and there are problems such as a small scope of application, and there are certain shortcomings. Summary of the invention

[0005] The purpose of the present invention is to solve the problems that the clamping type cover plate moving device is inconvenient to calculate the cover plate size, is easily disturbed by foreign objects during clamping, and easily causes the cover plate to fall off; the suction cup type cover plate moving device has high requirements on the flatness of the cover plate surface.
