Description

A kind of portable air-inflating type pontoon bridge

Technical field

The utility model is related to pontoon bridge technical fields, in particular relate to a kind of portable air-inflating type pontoon bridge.

Background technology

Pontoon bridge is actual life, production and construction, facility or equipment needed for floods rescue and military operation, institute at present The pontoon bridge of use probably has following type：Floating box type, buoyancy tank have the buoyancy tank of metal buoyancy tank, plastics buoyancy tank and other materials again；It is floating Body material formula, such as plastic foam, other light materials；Inflatable, air bag is done above floating body plus bridge floor of steel plate.Current practice Floating box type pontoon bridge the shortcomings that be larger volume, weight and it is heavier be not easy to storage, transport and installation.Floods are rescued to the mankind For, it always is a problem.Though nowadays science and technology is flourishing, various rescue run equipment emerge one after another, and most cost is high It is expensive so that can not promote or not Portable belt, be not suitable for masses.People are still to be helped stranded using simple rope or straight-bar Personnel are out of danger, but when the stranded time is longer, and trapped person loses consciousness or cannot save oneself, it is necessary to which rescue personnel is close Trapped person implements rescue.Current problem is：Lack an escape way between safety area to accident point, so that Rescue personnel is unable to fast approaching trapped person, or even rescue personnel and trapped person trapped situation once again together occurs.This When, there is an escape way that can quickly spread just, it appears particularly important.

Utility model content

The purpose of this utility model is to provide a kind of simple in structure, can Fast Installation, build rapidly, length-flexible can Become, dismounting combination is convenient, uses simple and safe portable aerating pontoon bridge.

The technical solution of the utility model is a kind of portable air-inflating type pontoon bridge, including air bag, gas tube, fixed chain component, Folded flat is provided on the air bag, the folded flat can fold from centre and be accommodated in the air bag wherein, described to fill For air supporting bridge by being formed by connecting by quick coupling between several air bags, the air bag end is provided with hose, the hose it Between can be connected by quick coupling, be located at air bag center through setting gas tube, the gas tube among the air bag and be equipped with Check valve a, tail portion are equipped with check valve b, sequence valve are arranged between the check valve a and check valve b.

Further, the air bag bottom is provided with safety valve and vent valve.

Further, hinge is set among the folded flat, is provided at both ends with padlock component, is folded by the hinge Later, the folded flat can form a box body, and the padlock component can lock box body.

Further, after the folded flat expansion, the protrusion in folded flat is fixed with tablet fixing sleeve.

Compared with prior art, the beneficial effects of the utility model are：

1, entire pontoon bridge is junior unit form, can increase and decrease unit as needed, more meet actual demand.Because inside is arranged A variety of valves, it is not necessary to worry replace unit process in pontoon bridge gas leakage because check valve can only one-way flow, each unit Gas storage be all an independent space.

2, because of the sequence valve being arranged in each unit, so in use, it will not be because of the destruction gas leakage of some unit The discouraged paralysis for causing entire pontoon bridge replaces damaged unit.

3, its intensity of the pontoon bridge of Conventional pneumatic formula is generally inadequate, when people walks above, because air bag is more soft and by Concentrfated load can be formed and more significantly be collapsed, and pedestrian's walking is unstable.The utility model is by folded flat and air bag upper surface Fitting is fixed completely, and concentrated force when pedestrian being made to walk is converted to uniform load, and pontoon bridge stress is steady, solves the problems, such as to collapse. In addition to this, tablet is foldable to box body, by fold, floor space smaller when tablet being made to store, be more convenient for storage, carry, It carries.Simultaneously as ingenious property when design, folding can make it is internal form a storage space, in can place deflation after Other external modules of air bag and the unit.

Specific implementation mode

As shown in figures 1 and 3, the utility model is a kind of portable air-inflating type pontoon bridge, including air bag 1, gas tube 2, fixation Chain component 3, folded flat 14 is provided on the air bag 1, and the folded flat 14 can fold from centre and store the air bag 1 In wherein, 1 end set of the air bag has hose 4, can be connected by quick coupling 5 between the hose 4, in the air bag 1 Between through setting gas tube 2.

As shown in Figure 2 and Figure 4, the gas tube 2 is located at air bag center equipped with check valve a6, and tail portion is equipped with check valve B7,1 bottom of the air bag are provided with safety valve 8 and vent valve 9, sequence valve are arranged between the check valve a6 and check valve b7 13。

As shown in Figure 5 and Figure 6, hinge 10 is set among the folded flat 14, is provided at both ends with padlock component 11, passes through After the hinge 10 folds, the folded flat 14 can form a box body, and the padlock component 11 can carry out box body Locking.After the folded flat 14 is unfolded, the protrusion in folded flat 14 is fixed with tablet fixing sleeve 12.

The specific work process of the utility model is as follows：Fig. 5 is the initial storage configuration of the utility model, the air bag 1 It is stored in the folded flat 14 to fold in the box body formed, box body can be locked with padlock component 11.1 upper table of air bag The folded flat 14 in face can carry out overturning folding by hinge 10, and after overturning, state is as described in Figure 1, can fold at this time Tablet fixing sleeve 12 is loaded onto in the prominence of tablet 14, ensures that folded flat 2 keeps flat state.After folded flat 14 is fixed, lead to Quick connection between two air bags can be realized by crossing the quick coupling 5 of 4 end of hose, be gone to determine that pontoon bridge is long according to specific requirements Degree.After connection, pontoon bridge is fixed by fixed chain component 3, ensures that pontoon bridge uses the stationarity of process.Chain length not shadow Ring the leap of user.Later, it is inflated in pontoon bridge left end using air pump.When gas just flows into the first length of tubing, because Middle and back is provided with sequence valve 13, and there are a pressure values to trigger for the sequence valve 13, when pressure value is inadequate, during air-flow passes through The check valve a in portion enters air bag 1.After air bag 1 is filled with certain gas, the pressure value in entire gas tube 2 gradually increases, and continues Inflation, when 2 internal pressure of gas tube reaches certain value, reaches certain pressure value constantly, and sequence valve 13 is opened, under gas enters One check valve b7 is hence into next air bag 1.Meanwhile it to ensure the safety of gas replenishment process, being equipped in 1 bottom of each air bag Safety valve 8 prevents air bag excessive and burst by pressure.It can be by putting after use equipped with vent valve 9 beside safety valve Gas is discharged in air valve.After the destruction of air bag 1, previous air bag 1 is since there are sequence valve 13, itself pressure of air bag 1 not enough touches Sequence valve 13 is sent out, so gas will not flow out in air bag.The latter air bag is since there are check valve b7 for preceding one end, so next The gas of air bag will not be flow backwards back.

Specific embodiment of the utility model is described in detail above, but it is intended only as one such implementation Example, the utility model are not restricted to particular embodiments described above.To those skilled in the art, any to this reality With the novel equivalent modifications carried out and substitute also all among the scope of the utility model.Therefore, the utility model is not being departed from Spirit and scope under made by impartial conversion and modification, should all cover in the scope of the utility model.
