Abstract

The utility model discloses a gangway ladder accommodation device which comprises a traction device and a gangway ladder, wherein the traction device is arranged on a gunwale deck, the gangway ladder is positioned under the gunwale deck, and the traction device consists of a pulley, a lifting frame, a support, an eye plate, a steel rope and a winch. In the gangway ladder accommodation device, one end of the gangway ladder positioned under the gunwale deck is hinged with an entrance, the gangway ladder integrally and horizontally props against the bottom surface of the gunwale deck when being accommodated, lateral pulleys are arranged at the two sides of a waist of the gangway ladder and face a reserved hole of the gunwale deck, the dual-lane synchronous lifting steel rope is arranged at a hoisting end of the traction device, the drooping steel rope passes through the reserved hole of the gunwale deck and is connected with the lateral pulleys at the two sides of the gangway ladder to form a swinging structure of the gangway ladder, the swinging structure takes a hinged connecting end as a shaft, when the traction device is lifted upward, the gangway ladder is accommodated, and when the traction device is released, the gangway ladder is moved down. With the adoption of the gangway ladder accommodation device, the gangway ladder is hidden under the gunwale deck, so that the limited position on the gunwale deck is not occupied, the gangway ladder can be reliably accommodated, and the gangway ladder accommodation device is simple and convenient to operate and can rise and fall fast; therefore, the gangway ladder accommodation device is favorable for loading and unloading operations on the deck and personnel access.

Description

The gangway ladder holding device fo

Technical field

The utility model relates to a kind of ship deck accessory machinery, and specifically, the utility model relates to a kind of gangway ladder holding device fo.

Background technology

The present age, large and medium-sized bulk carrier, box ship, oil tanker, chemical carrier, ro-ro passenger ship, and the equipped gangway ladder holding device fo in naval vessel mainly contains convertible and two kinds of structural shapes of parallel-moving type, the gangway ladder of being collected all is installed on the boats and ships side deck in the open.The gangway ladder holding device fo is simple in structure, collection is reliable although have now, can realize collection of gangway ladder fixed point and expansion.But existing gangway ladder holding device fo can only be positioned at gangway ladder on the side deck, and the gangway ladder that is in favorite places has occupied has extreme position on the side deck, reduce the side deck traffic potential greatly, and to ship loading and unloading goods and the certain obstacle of the current formation of personnel.In addition, doing the gangway ladder folding and unfolding during boats and ships inward & outward must be through upset or translation process, and this time, the sequencing action must increase gangway ladder folding and unfolding production time, directly incured loss through delay boats and ships from the time of approaching.

The utility model content

The utility model is primarily aimed at the deficiency of prior art, proposes a kind of gangway ladder holding device fo that does not take position above the side deck, and this apparatus structure is reasonable, and is swift to operate, safe in utilization, and favorite places is hidden.

The utility model is realized technical goal through following technical proposals.

The gangway ladder holding device fo, it comprises the draw gear that is installed on the side deck and is positioned at the gangway ladder under the side deck.Said draw gear is made up of pulley, suspension bracket, bearing, eye plate, cable wire and winch.Its improvements are: gangway ladder one end and the entrance that are positioned under the side deck are hinged, and integral planar leans against the bottom surface, deck during the gangway ladder collection, and the sideslip wheel that gangway ladder waist both sides are provided with is reserved the hole facing to side deck.The lifting end of said draw gear is provided with two pass synchronization lifting cable wire, and sagging cable wire passes side deck and reserves the sideslip wheel that the hole connects the gangway ladder both sides, and constituting gangway ladder is the swinging gear of axle to be hinged end.

The utility model compared with prior art has following good effect:

1, gangway ladder is collected under the side deck, does not take the position above the side deck, the current and loading and unloading operation of favourable personnel;

2, gangway ladder serves as that axle rotates to be hinged an end, last receipts or down the exhibition action single, easy and simple to handle, go up and down quick, collect reliably;

3, hidden chamber structure for use is simple, making is easy.

Description of drawings

Fig. 1 is that the utility model structure master looks scheme drawing.

Fig. 2 is Fig. 1 right elevation.

Fig. 3 is the train transmission scheme drawing in the draw gear.

The specific embodiment

According to accompanying drawing and combine embodiment, the utility model is described further below.

Gangway ladder holding device fo shown in the drawings, it comprises the draw gear that is installed on the side deck 8 and is positioned at the gangway ladder 5 under the side deck 8.Said draw gear is the pulley-type crane, and it is made up of pulley 1, suspension bracket 2, bearing 3, eye plate 4, cable wire 6 and winch 7.Symmetry is installed two groups of pulleys 1 on the top of suspension bracket 2 shown in Figure 2 and the crossbeam, and the cable wire 6 that winch 7 affects cooperates formation twice synchronization lifting train as shown in Figure 3 with each pulley 1.Gangway ladder 5 one ends and the entrance that are positioned in the utility model under the side deck 8 are hinged, and integral planar leans against side deck 8 bottom surfaces during the gangway ladder collection, and the sideslip wheel 5.1 that gangway ladder 5 waist both sides are provided with is facing to side deck 8 reservation holes.The lifting end of said draw gear is provided with two pass synchronization lifting cable wire 6, and sagging cable wire 6 passes the sideslip wheel 5.1 that side deck 8 reservation holes connect gangway ladder 5 both sides, and constituting gangway ladder 5 is the swinging gear of axle to be hinged end.During collection, draw gear promotes gangway ladder 5 through cable wire 6, till gangway ladder 5 is freely held level with both hands by 8 bottom surfaces, wales deck.The operation of putting down gangway ladder 5 is easy equally, as long as draw gear is made cable wire 6 loosen, by gravity gangway ladder 5 serves as that axle rotates with an end that is hinged with 8 entrance, wales deck, puts in place until free end decline.The utility model is hidden in gangway ladder 5 under the side deck 8, neither takies the position on the side deck, can accomplish reliable collection again, and is easy and simple to handle, and it is quick to go up and down, and loading and unloading operation and personnel that this structure helps on the deck are current.
