Abstract

The utility model discloses a step on ship's ladder safety couple belongs to the ship's ladder field of stepping on. Including couple, hydro -cylinder supporting seat, hydro -cylinder support seat pin axle, hydro -cylinder, hanger pin axle, couple seat pin axle and couple seat, hydro -cylinder supporting seat and couple seat respectively welded fastening on stand top plane, the couple articulates on the couple seat through couple seat pin axle, hydro -cylinder one end is passed through hydro -cylinder support seat pin axle and is hinged on the hydro -cylinder supporting seat, and the other end passes through the hanger pin axle and hinges on the couple. The utility model discloses can prevent the ladder danger that caused unexpected whereabouts under folded state, it can realize opening and closing through stretching out and drawing back of control hydraulic cylinder, and degree of automation is high, be convenient for operation and use.

Description

Boarding ladder safety hook

Technical field

This utility model belongs to a kind of boarding ladder equipment, specifically, particularly relates to a kind of boarding ladder safety hook.

Background technology

Boarding ladder is a kind of requisite equipment on modern harbour, go on board for crewman, need when not in use to be drawn on harbour, in order to prevent ladder unexpected whereabouts under rounding state, needs are further added by one safety hook, and in order to lock the main ladder of boarding ladder, current safety hook is manual, operator are needed to open and close, relatively inconvenient.

Utility model content

This utility model purpose is to provide the safety hook of a kind of boarding ladder, and to overcome, boarding ladder safety hook automaticity of the prior art is low, the defect of inconvenient operation.

This utility model realizes by the following technical solutions: a kind of boarding ladder safety hook, including hook, oil cylinder supporting seat, oil cylinder supporting seat bearing pin, oil cylinder, hook bearing pin, hook base bearing pin and hook base, described oil cylinder supporting seat and hook base are respectively welded and are fixed in column top planes, described hook by hook base hinge on hook base, described oil cylinder one end is by oil cylinder supporting seat hinge on oil cylinder supporting seat, and the other end is articulated with on hook by linking up with bearing pin.

Described supporting seat quantity is 1, and hook base quantity is 2.

Compared with prior art, the beneficial effects of the utility model are: this utility model is possible to prevent ladder surprisingly to fall under rounding state the danger caused, it can be opened and closed by flexible realization of control hydraulic jack, and automaticity is high, it is simple to operation and use.
