Description

Safe-typed combined climbing pole

Technical field

The present invention relates to the combination pole-climbing that a kind of fire-fighting is used.

Background technology

What enforcement high-altitude rescue at first will solve is exactly the personnel's of speedily carrying out rescue work the problem of ascending a height, can climb up fast the danger in high-altitude and send out the position, directly determining the success or not of rescue, therefore how to realize ascending a height fast is important research topic of rescue operation for a long time always, and the most important thing that ascending tool is studied beyond doubt.

The research of the current equipment of ascending a height of speedily carrying out rescue work is to motorization, high-endization development.With motor ladder, platform lift truck is the equipment of ascending a height in the various modern times of representative, mobility strong, easy to operate not only, and also accessible height is also more and more higher, and its advantage is by vast firefighters height approval.But the high price that its moving rut is up to a million, still underdeveloped concerning economy is a white elephant most local, and the equipment that has limited fire brigade uses, and especially this class equipment bodily form is huge, deadweight is huge, very harsh to the using area requirement, greatly restricted its combat performance.Take current domestic the most small-sized fire-fighting ascending platform car (22 meters) as example, require 10 meters of operation field radiuses, spaciousness is smooth, ground is solid, and the space does not have obstruction, and horizontal direction is not more than 6 meters apart from the rescue target, and this equipment of no person can only be an ornament.

The ascend a height research of equipment but stays cool for many years to traditional manpower, various attic ladders, short extension ladder are traditional ascending tool of representative, its form of structure and material recent decades are almost without any improvement, these instruments all exist fatal deficiency, carry easy to operate climbing highly too low (below 5 meters); Climb highly slightly high (9 meters are drawn ladder can arrive 7.5 meters) structure heavy, carry operation inconvenience; Behind Luoyang 12.25 fire in 2000,15 metals draw ladder equipment fire brigade, highly extend to 12 meters although can climb, to carry unhandy problem more outstanding but nearly 200 kilograms weight and huge volume make, and very high request has been proposed usage space, need to operate and to use by 8 people at the spacious smooth location that is not less than 8*12 square metre, and the complete operation time long (uncart in the situation of normal operating to holding up fully approximately and need 10 minutes to 20 minutes), the effect that promotes fighting capacity is very undesirable.In addition fire brigade has also been equipped rope ladder, although solved problem easy to carry, can only be from eminence to downward-extension, and climbing effort very.

In the last few years along with the continuous quickening of socioeconomic fast development and urbanization process, huge variation is occuring in urban architecture, in small and medium-sized cities (town) although take rancher or two-story house room as the local-style dwelling houses of primary structure form by the multi-storey building of 5-7 layer replace, tens meters, up to a hundred meters highrise building is in continuous increase in the metropolis, the multi-storey building of 5-7 layer remains the primary structure form of industry and civilian construction.Because the requirement that China's fire prevention standard is built the face of suing and labouring of ascending a height to this class is not strict, unreasonable and the execution of urban planning is ineffective in addition, the novel ascending tool of ladder truck and so on often can't use because of the place restriction in the suing and labouring of this class Building disaster, even 15 meters metals draw ladder, also many narrow and small local lack scope for their abilities, vehicle is expensive because ascend a height, the basic outfit of the Small Urban of financial strain does not rise, when the above breaking out of fire in the 4th buildings or plate indicates nature of danger, the fire fighter also feels simply helpless.During the situation particularly urgent, have to sue and labour by the free-hand climbing of building structure, physical demands is huge, dangerous high, feasible highly reluctantly below ten meters, higherly more not only be full of peril, rescue personnel's muscle power can not propped up yet, even climbing puts in place, also flabbiness has been finished the task of suing and labouring again.

Implement the responsibility that new " People's Republic of China's fire control law " revised given again public security fire-fighting army rescue in May, 2009, speedily carry out rescue work in the high-altitude or the actual combat number of times of high-altitude relief increases greatly, the high-altitude rescue more and more becomes the day-to-day work task of public security fire-fighting army, vehicle or the vehicle of ascending a height can't use in the situation that do not ascend a height, how could ascend a height fast simultaneously can maintain again enough rescue muscle power and become an extremely important and very urgent research topic, makes especially the extremely urgent significant problem that solves of needing of fire-fighting iron army.
