Problems solved by technology

If the threshold is not required, the isolation door may rub against the ground when it is opened and closed, and there will be a gap under the door. One edge is missing, and the safety of the door is also affected.
Therefore, the current isolation door frame structure of the fixed threshold brings certain inconvenience to the user during use.

Embodiment 1

[0028] Such as Figure 1-3 As shown, a detachable or hidden threshold structure for a ship includes a door frame, a threshold 1 and a lifting structure. The left end and the right end of the threshold 1 are respectively matched with the left and right door frame pillars 2. Connected by bolts, the threshold 1 is U-shaped with a horizontal bottom surface, a slider 5 is provided on the opposite side of the threshold 1 to the stop of the threshold 1, and a top-end closure is provided on the inner side of the door frame column 2 in the cabin. The chute 3 and the limiter, the limiter is a combination of two sets of limit insert rods and pin holes 4, the distance between the pin hole 4 and the top of the chute 3 is the same as that of the slider 5 and the two ends of the threshold The distance between the screw holes on the spigot is equal, and the aperture size and position of the screw holes on the sill 1 two ends of the pin hole 5 match.

Abstract

The invention discloses a detachable or hidden door sill structure for a ship. The detachable or hidden door sill structure comprises a door frame and a door sill. The left end and the right end of the door sill are matched with door frame stand columns on the left and right sides correspondingly, and the door sill is in a U shape or a long-strip shape with a horizontal bottom surface. The door sill structure further includes a lifting structure or a turnover structure or an inflatable structure. The bottom surface of the door sill is horizontal and combined with the door frame stand columns to enable the structure of the door frame to be safe and firm, and the door sill is sealed with the ground to reduce the influence of waves; the door sill has a detachable or hidden function, and the door sill can be lifted and lowered, hidden or turned over when cargo passes, so that the door sill position of an access door is located on the same plane as the ground plane, and communication without any obstacles can be achieved; and a door sill limiting fixing member is arranged to prevent the door sill from slipping off and affecting the safety of entering and exiting personnel and cargo.

Description

technical field [0001] The invention relates to the technical field of sills, in particular to a detachable or concealed sill structure for 18,600-ton chemical tankers. Background technique [0002] At present, usually two steel doors are set on the left and right sides of the front wall of the superstructure on the ship as the isolation door between the cargo hold area and the residential area of ​​the superstructure. This door can effectively reduce the impact of waves on the superstructure area during navigation. When the dock is berthing, it can also be used as an isolation door for emergency escape plans to prevent and reduce unauthorized personnel from entering and exiting the superstructure area. [0003] The door frame of the isolation door is generally closed all around, that is, there are edges on the upper, lower, left, and right sides. After installation, the lower edge is higher than the ground, which is called the threshold. Sometimes, when it is necessary to ...
