The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art part, provide a kind of simple in structure, light and handy, be easy to carry and safe in utilization, convenient, both can be used as fire-fighting, salvor and climbed the instrument of ascending a height of building, can be used as evacuation, the personnel of taking refuge again and withdraw the escape way of building, building is not had the backpack security against fire ladder of any transformation and destruction.

The purpose of this utility model can reach by implementing following technical proposal: the back of the body frame of bearing for personnel is provided with the telescope support that is made of plurality of sections pole fit, its top is provided with rotating tape guide, the lower end of back of the body frame is provided with down rotating tape guide, be connected with annular rope ladder by upper and lower rotating tape guide and round described back of the body frame, telescope support, be evenly distributed with 2 to 5 elastic hooks on it.Described telescope support preferably forms with the extension ladder fit, and its every section extension ladder is provided with alignment pin; Described upper and lower rotating tape guide with the roller bar type for well; Above-mentioned rope ladder is good with rope ladder then, preferably evenly is equiped with 3 elastic hooks on it.

Accompanying drawing is the structural representation of the utility model embodiment.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.The back of the body frame 2 that braces 1 is housed is provided with the telescoping shoring column 4 that is formed by three sections ladder type pole 3 fits, and the top of every section pole 3 is provided with alignment pin 5.The lower end of the top of this telescope support 4 and back of the body frame 2 is equipped with conduction band running roller 6 respectively and is reached conduction band running roller 7 down.By being wound with annular rope ladder 9 on the described upper and lower conduction band running roller 6,7 and in described back of the body frame 2, telescope support 4 external rings with 3 even distribution elastic hooks 8.When using the utility model product, only need stretch telescope support 4 and be fixed with alignment pin 5, braces 1 are carried on the back in user's back to get final product then.Upwards climb when needs and to succour, when speedily carrying out rescue work, only need the annular rope ladder 9 of pulling to make after any one elastic hook 8 hooks the balcony or windowsill of last layer building it on, along rope ladder 9 climbings on.At this moment, telescope support 4 is ascended a height with the scaler and is boosted, and rope ladder 9 slides on upper and lower conduction band running roller 6,7 and himself then keeps hanging stable state; Evacuate downwards and when pulling out of dangerous places when needs, after only needing user's elastic hook 8 at one's side hooked balcony or windowsill with the floor room, climb down step by step along rope ladder 9.At this moment, telescope support 4 is climbed down with the user and is passed downwards, and rope ladder 9 slides on upper and lower conduction band running roller 6,7 and himself then keeps hanging stable state.Because itself does not bear gravity to 4 of telescope supports as traction rope ladder 9 and the usefulness that takes hook 8, and is therefore less demanding to its structure and intensity etc.

The utility model compared with prior art, have simple in structure, light and handy, be easy to carry and use safety, Facility both can be used as the ascending tool that building is climbed in fire-fighting, salvor, can be used as again evacuation, personnel take refuge Withdraw the escape way of building, building is not had the characteristics such as any change and destruction, be suitable as and speedily carry out rescue work, rescue And the safety equipment of taking refuge.
