Abstract

An embedded type bitt comprises a body, and is characterized in that a concave cavity is formed on the body, a connecting column is arranged at the middle part of an upper end opening of the concave cavity, the two ends of the connecting column are connected with two sides of the body, and a hollow cavity is formed between the connecting column and the inner wall of the concave cavity for penetrating a cable. The body is cast to form in one step so that both the manufacture and the installation are very convenient, which solves the personnel safety problems brought forth by the shake and unsteadiness of a gangway; when the bitt is installed, only are mounting holes punched on external plates of the left and right shipboards, and then the bodies can be embedded in the holes to be welded and fixed onto the external plates; when in use, the bitt can be conveniently connected with the gangway through connecting parts such as ropes and the like so that a lower platform of the gangway can safely lean against the shipboard, which conforms to the disciplines of SOLAS (Convention on the Safety of Life at Sea) V/23 and A.889(21); and the embedded type bitt not only has a simple structure, but also is convenient in both mounting and use.

Description

The flush type cavel

Technical field

The utility model relates to a kind of accessory peculiar to vessel, specifically is a kind of flush type cavel that is applicable to that the gangway ladder that disposes on the large ocean boats and ships and pilot's gangway ladder are united use.

Background technology

The gangway ladder that disposes on the general boats and ships all is the outside that hangs over ship, like this when Ship Swaying, causing that gangway ladder and pilot's rope ladder rock causes the descending stair personnel to be in dangerous condition, now, International Convention for the Safety of Life at Sea SOLAS V/23 and A.889 (21) require ship side to be provided with to make gangway ladder lower platform safe sticker be against the device of ship side.

Though, Chinese National Standards GB and shipbuilding industry standard C B do not have to solve this problem at above-mentioned requirements formulation relevant criterion at present, but consider for personal safety, be necessary to design one, satisfy safe requirement the solid device together of gangway ladder and ship side system to the pilot.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of flush type cavel that is arranged on the ship hull plate at the above-mentioned state of the art, and is simple in structure, easy for installation, as long as just can gangway ladder and ship side system is solid together by attaching partss such as hawsers.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of flush type cavel, comprise body, it is characterized in that: form a cavity on the described body, upper port middle part at cavity is provided with a joint pin, the two ends of joint pin link to each other with the both sides of body, form the cavity that places for hawser between joint pin and cavity inwall.

Preferably, described joint pin is along the line of centers setting, and with the end face of body.

Preferably, described cavity cross section is a circular arc.

As improvement, the edge of opening of described cavity is provided with the edge of outside turnover, and the two ends of described joint pin are widened gradually with the edge and linked into an integrated entity.

As improvement, described body and joint pin are the integrative-structure of a cast molding.

Further improve, the shell of described body is hemispherical, and in the installation eyelet that described body embedding ship hull plate is offered, edge and outside plate develop and weld fixing.

At last, the internal diameter of described cavity is 180-220mm, and the diameter of described joint pin is 28-32mm, and thickness is 23-27mm between described cavity and the body housing.

Compared with prior art, advantage of the present utility model is: body adopts a cast molding to make to make and installs all easily, has solved the problem that gangway ladder rocks the personal safety that shakiness causes; During installation, need only and on the outside plate on port or the starboard, offer the installation eyelet, body is embedded in the eyelet weld fixing getting final product with outside plate; During use, can be connected with gangway ladder by attaching partss such as ropes easily, make the lower platform of gangway ladder to be posted by ship side safely, meet the International Convention for the Safety of Life at Sea SOLAS V/23 and the regulation of (21) A.889; The utility model is not only simple in structure, and installs and uses all very convenient.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in the figure, a kind of flush type cavel, comprise body 1, the shell of described body 1 is hemispherical, forming a cross section in the center is the cavity 11 of circular arc, is provided with the edge 12 of outside turnover at the edge of opening of cavity 11, is provided with a joint pin 2 in the upper port of cavity 11 along line of centers, the two ends of joint pin 2 are widened gradually with edge 11 and are linked into an integrated entity, and joint pin 2 flushes along 12 with the end surface side of body 1; Described body 1 and joint pin 2 are the integrative-structure of a cast molding, and the external diameter of body 1 is 250mm, and the internal diameter of cavity 11 is 200mm, wall thickness 25mm, and joint pin 2 diameters are 30mm.

During installation, offer the installation eyelet on the left and right sides outside plate on the quarter earlier, the body 1 of flush type cavel is embedded in the eyelet, make the edge 12 of body 1 develop, and welding is fixing, can finish installation with outside plate, during use, attaching partss such as hawser are passed joint pin 2 be connected and fixed, just gangway ladder can be posted by ship side and stablize, can use safely with gangway ladder.

Embodiment of the present utility model discloses optimum implementation, can not be interpreted as the restriction to the utility model protection domain, and every employing is equal to or the similar techniques means are replaced, all within protection domain of the present utility model.
