Abstract

The utility model discloses a portable multifunctional climbing ladder which comprises a plurality of ladder column units with same structures and sleeved with each other in a telescoping manner. Each column unit is formed by two side longitudinal beams and a plurality of crossbeams. The climbing ladder is characterized in that hanging hooks capable of being folded inwards or unfolded outwards are connected on two sides of the first crossbeam of the lowest column unit of the climbing ladder close to the longitudinal beams respectively; and the unfolded hanging hook is vertical to the longitudinal beams. The utility model expands the single function of the climbing ladder to multiple functions of climbing, bullet prevention, stretcher and blindage, uniquely realizes the climbing mode of vertical climbing, expands practical range, particularly can make surprise in the defeat of enemies under complicated battle environment.

Description

Portable multifunctional is climbed ladder

Technical field

The utility model relates to a kind of climbing equipment, particularly relates to a kind of portable climbing ladder of realizing two kinds of climbing forms and possessing a plurality of functions.

Background technology

Portable climbing ladder has now obtained in dual-use various fields using widely, and will progressively develop into a kind of climbing equipment that plays a significant role with himself quality advantage little, easy to carry.

Existing portable climbing ladder mainly contains telescopic and collapsible two classes both at home and abroad at present, they are respectively will climb the length elongation of terraced main body or dwindle by scalable in the structure design and folding characteristics, make it can bring into play the effect of climbing in use, simultaneously again can be when depositing or carry volume-diminished, flexible.Though it is different on form of structure that this two class is climbed ladder, but they have a common deficiency is exactly function singleness, only possess unique climbing function, can not satisfy the instructions for use under the complex environment, especially can not satisfy the war fighting requirements of department under particular surroundings such as People's Armed Police, public security.Therefore the climbing form of existing portable climbing ladder and the function that is possessed also had further perfect space.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, easy to carry, function is many, integrate climbing, shellproof, stretcher, a plurality of functions of blindage, and is specially adapted to the climbing ladder of the complicated operational environments of departments such as People's Armed Police and public security.

For reaching above purpose, the utility model takes following technical scheme to be achieved:

A kind of portable multifunctional is climbed ladder, comprise the identical cleat stanchion unit of multi-section structure that telescopic suit is formed, every joint cleat stanchion unit is connected and composed by two side girders and some crossbeams, it is characterized in that, connect respectively near the longeron both sides at first crossbeam climbing the bed ladder pole unit of ladder and have the hook that selectivity is inwardly folding and outwards open.

In the such scheme, being connected to of described hook and crossbeam: have the through hole that connects the crossbeam top and bottom near the longeron both sides at first crossbeam, the upper and lower brace that has installing hole is established in the hook rear end, the free end of brace is semicircle, to be linked up with crossbeam with installing hole by described through hole by a bolt and nut and be connected, bolt is realized that as axis of rotation hook is inwardly folding again or is outwards opened simultaneously.Described hook upside is the taper serration shape.

It is shellproof fluffy on a plane climbing ladder one deck to be set, and the mode by double buckle or belt fastener is fixed on the longeron of climbing the terraced left and right sides.

First crossbeam one side of joint and time fly pole unit is respectively arranged with the connected mode bracing frame identical with hook under the climbing echelon, can have shellproof fluffy climbing ladder diagonal brace on the ground.

The utility model will have the simple function of climbing ladder now and expand to climbing, shellproof, stretcher and four functions of blindage, and realized the scaling mode of vertical climbing uniquely, enlarge usage range more, especially in the antagonism operational environment of complexity, can bring into play the effect of defeating by a surprise move.

Fig. 4 is another kind of user mode figure of the present utility model.

Among Fig. 1 to Fig. 4: 1, crossbeam; 2, longeron suit joint; 3, longeron; 4, bolt; 5, hook; 6, hook brace; 7, hook installing hole; 8, nut; 9, bracing frame; 10, shellproof fluffy; 11, balcony; 12, the vertical exterior wall of building.

The specific embodiment

Shown in Figure 2 as Fig. 1, this terraced main body adopts telescopic structure design, form by the nine joint cleat stanchion unit suits that structure is identical, size is ascending, every joint cleat stanchion unit is made up of two side girders 3 and some crossbeams, and save 2 inside at the longeron suit and be provided with spacing lockable mechanism, thereby the stretching and the contraction that realize climbing ladder.Have the through hole that connects the crossbeam top and bottom in first crossbeam 1 both sides climbing the bed ladder pole unit of ladder, be used for the hook 5 of the oblique sawtooth of connecting band.Link up with 5 rear ends and establish the upper and lower brace 6 that has installing hole 7, the free end of brace 6 is semicircle, to link up with 5 by bolt 4 is connected with crossbeam 1, bolt 4 can be used as an axle and realizes that hook 5 inwardly folds and outwards opens simultaneously, when hook 5 is outwards opened, itself and longeron 3, crossbeam 1 all meet at right angles, and climb ladder and can hang upside down on the vertical object such as limb in trees, balcony thereby make, and realize vertical scaling mode (Fig. 4).The utility model is climbed terraced material of main part can select light weight, intensity height, high temperature resistant, rust-preventing aluminum alloy that corrosion resistance is good for use.

As shown in Figure 3, Figure 4, be provided with on a plane climbing ladder that one deck can mount and dismount flexibly shellproof fluffy 10, shellproof fluffy can making by the bullet resistant material aramid fiber, or high-tenacity polyethylene fibre (Di Nima that produces as Dutch DSM company) is made, mode by double buckle or belt fastener is fixed on the longeron 3 of climbing the terraced left and right sides, for operation provides bulletproof function.Simultaneously, save at the 3rd joint and the 7th of climbing ladder respectively bracing frame 9 (with linking up with 5 identical connected modes) is set on the crossbeam 1, will have shellproof fluffy 10 climbing ladder diagonal brace on the ground, can be used for as blast shelter.In addition, utilize bullet resistant material that fixes and the stretching of climbing terraced main body joint can realize the stretcher function, provide easy equipment for shifting the wounded.
