的とする。This type of device consists of a torque arm connected to the tip of a rod protruding from a hydraulic cylinder, and a door body rotatably attached to the tip of the torque arm.The door body rotates due to the reciprocating movement of the rod. It is starting to occur.
However, such hydraulic equipment is often submerged in muddy water, and as a result, dirt may enter the hydraulic cylinder, especially from the tip of the cylinder, damaging the internal water-stop packing, or causing dirt to become trapped. This caused the door to become inoperable, and it was often impossible to open the door when necessary. (Summary of the Invention) The present invention has been made in view of the above circumstances, and is applicable to cases where a failure occurs in the hydraulic system for driving the door body and the condition of the door body driven by the hydraulic system becomes impossible. Another object of the present invention is to provide a device in which the door body can be adjusted by other means.
