Abstract

The invention discloses a device for opening and closing a pushing-pulling rotary type opening hole cover. The device comprises an opening drum body, a main shaft seat and an outer plate, wherein the main shaft seat is fixed on the outer plate and is internally provided with a main shaft; the main shaft seat is fixed with the opening drum body in a supporting manner by a rib plate; the lower end of the main shaft is provided with the opening hole cover; and the outer ring of the opening hole cover is coincided with the corresponding section of the inner ring of the opening drum body. The device disclosed by the invention has the advantages that the main shaft is pushed out, rotated, reversely rotated and retracted by a mechanical or hydraulic driving mode, so that the opening hole cover combined with the main shaft is driven to realize opening and closing of the opening, the occupied time when the hole cover of a ship is opened and closed is effectively reduced, the opening and closing of the hole cover are simple and labor-saving, and the repair and the maintenance are very convenient.

Description

The rotating opening port lid of a kind of push-and-pull headstock gear
Technical field
The present invention relates to ship domain, relate in particular to the rotating opening port lid of a kind of push-and-pull headstock gear.
Background technology
On some boats and ships, usually be designed with at present some special purposes the hole or wide open mouthful, in order to prevent the intrusion of seawater, these openings all are provided with door, lid, its general all installation with the hinge form connects, and realizes that the upset of door, lid opens and closes.Yet the door of these forms, lid maintenance difficulty take up room large, and opening rear normal use to boats and ships has certain negative effect.
Summary of the invention
The object of the present invention is to provide a kind ofly to take up room littlely, simple in structure, reliability is high, can bear the rotating opening port lid of the push-and-pull headstock gear of larger external pressure.
The present invention realizes like this, the rotating opening port lid of a kind of push-and-pull headstock gear, comprise opening cylindrical shell, spindle drum, outside plate, it is characterized in that: be fixed with spindle drum on the outside plate, be provided with main shaft in the spindle drum, described spindle drum is fixed by gusset and opening barrel support, and described main shaft lower end is provided with the opening port lid, and the cross section corresponding with opening cylindrical shell inner ring, described opening port lid outer ring coincide.
The present invention with machinery or hydraulically powered mode to main shaft release, rotate, reverse rotation, indentation, thereby drive the keying that the opening port lid that combines with main shaft is realized opening, effectively reduced the space that takies when the boats and ships port lid opens and closes, port lid is opened, closes simply laborsaving, and maintains very convenient.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure 1, the opening cylindrical shell, 2, the opening port lid, 3, main shaft, 4, spindle drum, 5, outside plate.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
The rotating opening port lid of a kind of push-and-pull headstock gear, comprise opening cylindrical shell 1, spindle drum 4, outside plate 5, it is characterized in that: be fixed with spindle drum 4 on the outside plate 5, be provided with main shaft 3 in the spindle drum 4, described spindle drum 4 supports fixing by gusset and opening cylindrical shell 1, described main shaft 3 lower ends are provided with opening port lid 2, and the cross section corresponding with opening cylindrical shell 1 inner ring, described opening port lid 2 outer rings coincide.
During implementation, the power that main shaft 3 is accepted from machinery or hydraulic pressure transfer, main shaft 3 can slide, rotate spindle drum 4 is interior, when opening port lid 2 is opened, main shaft 3 is outwards motion first, promotes opening port lid 2 to certain distance, opening port lid 2 is broken away from the boats and ships opening come, then main shaft 3 drive opening port lids 2 rotate to an angle, thereby opening port lid 2 is thoroughly opened; If close opening port lid 2, main shaft 3 drives opening port lid 2 reverse rotation certain angles, and then main shaft 3 inwardly drives 2 indentations of opening port lid, and opening port lid 2 is closed.
