Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing:

[0009] A push-pull rotary opening and closing device for opening and closing holes, comprising an opening cylinder body 1, a main shaft seat 4, and an outer plate 5, characterized in that: the outer plate 5 is fixed with a main shaft seat 4, and the main shaft seat 4 is provided with a main shaft 3, so that The main shaft seat 4 is supported and fixed by the rib plate and the open cylinder body 1, and the lower end of the main shaft 3 is provided with an opening hole cover 2, and the outer ring of the opening hole cover 2 matches the corresponding section of the inner ring of the opening cylinder body 1.

[0010] During specific implementation, the main shaft 3 receives power from mechanical or hydraulic transmission, the main shaft 3 can slide and rotate in the main shaft seat 4, and when the opening hole cover 2 is opened, the main shaft 3 moves outwards earlier, pus...

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

technical field [0001] The invention relates to the field of ships, in particular to a push-pull rotary opening and closing device for an opening hole cover. Background technique [0002] At present, some special-purpose holes or hole openings are often designed on some ships. In order to prevent the intrusion of seawater, these openings are equipped with doors and covers, which are generally installed and connected in the form of hinges to realize the flipping and opening of the doors and covers. . However, these types of doors and covers are difficult to maintain, occupy a large space, and have a certain negative impact on the normal use of the ship after being opened. Contents of the invention [0003] The purpose of the present invention is to provide a push-pull rotary opening and closing device for the opening and closing of the hole cover, which takes up little space, has a simple structure, high reliability, and can withstand relatively large external pre...
