Abstract
The invention relates to a dual-section folding contraction and release boarding ladder, which comprises a first section of steel pipe and a second section of steel pipe, wherein the first section of steel pipe and the second section of steel pipe are connected with each other through a movable connection shaft; a first section of cross beam and a second section of cross beam are horizontally arranged on the two steel pipes respectively; a strip-type clamping plate is arranged on the side face of the first section of cross beam; a fixing ring with a bayonet is sleeved at the lower end of the first section of steel pipe; and an open-type buckle is in butt joint with the outer side of the fixing ring. The dual-section folding contraction and release boarding ladder has the beneficial effects that a clamping piece consisting of the fixing ring and the open-type buckle is arranged between two movably folded ship ladder steel pipes, so that the two steel pipes can be clamped in two directions; during starting, the clamping piece can be detached; by the structure, the structure of the stainless steel pipes of the boarding ladder cannot be destroyed, and sea water can be prevented from entering the steel pipes; two sections of adjacent ladders can be clamped with each other; and the dual-section folding contraction and release boarding ladder has the advantages of relatively high stability, simplicity in assembling, adjustable position and the like.
Description
Technical field
The present invention relates to a kind of boarding ladder, relate in particular to the boarding ladder of the collapsible folding and unfolding of a kind of two section.
Background technology
Boarding ladder is the ladder for naval vessel about the personnel or upper lower decks, generally used shipyard, harbour, passenger steamer and other engineering construction operating personnel, it mainly is the rectangular bar of steel structure boarding ladder that can vertically spiral up, for keeping stable floor space larger, if in the limited space of floor space, then can be because occurring highly too greatly unstability to a certain degree and rock, therefore, after using, need to pack up or fold.For example, connect by buckle between per two joints of a lot of ship's ladders, not the time spent, need folding being convenient to put; For the ship's ladder accident after folding is opened, need to use the opening buckle, the opening buckle is fixed in by screw on the stainless steel tube of ship's ladder, when shrinking ship's ladder, only needs the stainless steel tube of next joint ship's ladder is snapped in the opening that open card buckles.But this kind opening buckle needs screw to be fixed in the stainless steel tube of ship's ladder, has reduced the stainless steel tube fastness and makes easily seawater enter in the stainless steel tube, easily produces corrosion phenomenon.Therefore, for above aspect, need to reasonably improve prior art.
Summary of the invention
For above defective, the invention provides a kind of with the detachable card cuff structure, can realize that the adjacent mutual clamping of ship's ladder of two joints, stability are better, assembling easily, the boarding ladder of the collapsible folding and unfoldings of two section of position-adjustable, to solve many deficiencies of prior art.
For achieving the above object, the present invention is by the following technical solutions:
The boarding ladder of the collapsible folding and unfolding of a kind of two section, comprise first segment steel pipe and second section steel pipe, between described first segment steel pipe and the second section steel pipe by be flexibly connected that axle is connected and two joint steel pipes on respectively level installation first segment crossbeam, second section crossbeam, be positioned at first segment crossbeam side and be provided with the bar shaped clamp; Be positioned at retainer plate with bayonet socket of first segment steel pipe lower end socket, opening buckle of this retainer plate outside docking, described opening buckle arranged outside has a bayonet socket.
The beneficial effect of the boarding ladder of the collapsible folding and unfolding of two section of the present invention is: by between two sections movable folding ship's ladder steel pipes the fastener that is comprised of retainer plate and opening buckle being set, can realize the two-way clamping to two steel pipes, when opening, fastener can be dismantled, this structure can not have to the stainless steel tube of ship's ladder any structural destruction, can avoid seawater to enter steel pipe, be conducive to realize the adjacent mutual clamping of ship's ladder of two joints, have the advantages such as stability is better, assembling is easy, position-adjustable.
Description of drawings
The below is described in further detail the present invention with reference to the accompanying drawings.
Fig. 1 is the boarding ladder structural representation of the collapsible folding and unfolding of the described two section of the embodiment of the invention.
Among the figure:
1, first segment steel pipe; 2, second section steel pipe; 3, be flexibly connected axle; 4, first segment crossbeam; 5, second section crossbeam; 6, clamp; 7, retainer plate; 8, opening buckle.
The specific embodiment
As shown in Figure 1, the boarding ladder of the collapsible folding and unfolding of the described two section of the embodiment of the invention, comprise first segment steel pipe 1 and second section steel pipe 2, between described first segment steel pipe 1 and the second section steel pipe 2 by be flexibly connected that axle 3 is connected and two joint steel pipes on respectively level installation first segment crossbeam 4, second section crossbeam 5, be positioned at the clamp 6 that first segment crossbeam 4 sides are provided with bar shaped; Be positioned at retainer plate 7 with bayonet socket of first segment steel pipe 1 lower end socket, this retainer plate 7 outsides opening buckle 8 of docking and this opening buckle 8 arranged outside have a bayonet socket.
Above embodiment is the more preferably specific embodiment a kind of of the present invention, the common variation that those skilled in the art carry out in the technical program scope and replace and should be included in protection scope of the present invention.
Claims (2)
1. the boarding ladder of the collapsible folding and unfoldings of a two section, comprise first segment steel pipe (1) and second section steel pipe (2), it is characterized in that: between described first segment steel pipe (1) and the second section steel pipe (2) by be flexibly connected that axle (3) is connected and two joint steel pipes on respectively level installation first segment crossbeam (4), second section crossbeam (5), be positioned at first segment crossbeam (4) side and be provided with bar shaped clamp (6); Be positioned at first segment steel pipe (a 1) lower end socket retainer plate with bayonet socket (7), this retainer plate (7) outside docking opening buckle (8).
