Description

Technical Field

[0001] The utility model belongs to the technical field of ship attachment devices, in particular to a protective cover of a hydraulic cylinder of a mud barge arm. Background Art

[0002] Mud barges are barges used to transport dredged mud and sand in cooperation with chain bucket dredgers, bucket dredgers and grab dredgers. There are two types: self-propelled and non-self-propelled. Mud barges are available in open-bottom, open-side and closed-bottom types. There are movable mud doors on the bottom of the open-bottom mud barge, and movable mud doors on the bilges on both sides of the open-side mud barge. The mud can be unloaded automatically by opening the mud doors. The load capacity of the mud barge is about 50-2000 tons. In order to realize the self-unloading of mud by opening the mud doors, a lifting arm hydraulic cylinder is required to control the opening and closing of the mud doors.

[0003] The arm hydraulic cylinders that control the opening and closing of the mud gates are all set below the ship deck, that is, the ship deck is provided with grooves for installing the arm hydraulic cylinders, and the top and both ends of the arm hydraulic cylinders are exposed, without any cover, which makes it very easy for debris to fall, and may even cause workers to slip and fall. In order to facilitate the inspection and maintenance of the arm hydraulic cylinders, and to prevent debris from falling or people from stepping on empty space, they are generally covered with a baffle or an iron net, but they are not fixed or bolted to the ship deck. The shaking of the ship or strong winds may throw the baffle or iron net away from the covering position. Therefore, it is necessary to design a protective cover for the arm hydraulic cylinder of a mud barge. Summary of the invention
